本发明涉及烹饪装置领域，更具体而言，涉及一种嵌入式微波烤箱。The invention relates to the field of cooking devices, more specifically, to an embedded microwave oven.
背景技术Background technique
微波烤箱是一种带微波功能的烤箱，为实现烤箱的快速升温特点，要求腔体是封闭的，但使用微波功能时，为使腔体内部水蒸气顺利排出，确保门体透视窗清晰可见，需要对腔体进行通风，封闭与通风二者矛盾。当前嵌入式微波烤箱的风道设计为风扇后置，通过整机与橱柜之间间隙或者橱柜预留间隙吸风对电器件进行冷却，然后从门体与控制盒间隙、门体与橱柜下边缘间隙排出。当开启微波加热时，通过可控的开关打开腔体通风口，对腔体进行通风；当开启热风或者烧烤加热时，关闭腔体通风口，确保温度可较快的上升。但由于进风通道依赖橱柜，橱柜尺寸达不到设计要求时，整机与橱柜之间间隙不足，使得微波烤箱进气量得不到保证，影响产品的散热效果，导致电器件温升过高，因此容易造成产品安全性能问题。Microwave oven is an oven with microwave function. In order to realize the rapid temperature rise of the oven, the cavity is required to be closed. However, when using the microwave function, in order to discharge the water vapor inside the cavity smoothly and ensure that the perspective window of the door body is clearly visible, The cavity needs to be ventilated, and there is a contradiction between sealing and ventilation. The air duct of the current built-in microwave oven is designed with the fan behind, and the electrical components are cooled through the gap between the whole machine and the cabinet or the gap reserved for the cabinet, and then from the gap between the door body and the control box, the door body and the lower edge of the cabinet. Gap discharge. When the microwave heating is turned on, the cavity vent is opened through a controllable switch to ventilate the cavity; when the hot air or barbecue heating is turned on, the cavity vent is closed to ensure that the temperature can rise quickly. However, since the air intake channel depends on the cabinet, when the size of the cabinet does not meet the design requirements, the gap between the whole machine and the cabinet is insufficient, so that the air intake of the microwave oven cannot be guaranteed, which affects the heat dissipation effect of the product and causes the temperature rise of electrical components to be too high , so it is easy to cause product safety performance problems.

本方案中，嵌入式微波烤箱的壳体和腔体间形成冷却风道，壳体进风口和壳体出风口都开设在壳体前板上，这样设计冷却风道完全处于产品内部，进出风不受橱柜尺寸影响，散热稳定可靠，即使在橱柜尺寸达不到设计要求时，也可实现良好的散热效果，防止出现电器件温升超标的问题，从而保证产品可运行的安全性和稳定性。In this solution, a cooling air duct is formed between the shell and the cavity of the embedded microwave oven, and the air inlet and air outlet of the shell are set on the front plate of the shell. It is not affected by the size of the cabinet, and the heat dissipation is stable and reliable. Even when the size of the cabinet does not meet the design requirements, it can achieve a good heat dissipation effect and prevent the problem of excessive temperature rise of electrical components, thereby ensuring the safety and stability of the product. .
并且现有技术中的嵌入式微波烤箱依赖机身和橱柜间的间隙进风或出风，因此在使用微波加热功能时，腔体内排出的水蒸气会进入橱柜内，这样会对橱柜造成一定损害，影响橱柜的使用寿命。而本方案提供的嵌入式微波烤箱的冷却风道完全处于产品内，由壳体前板出风，以保证腔体内排出的水蒸气不会与橱柜内部接触，避免对橱柜造成损害，从而可延长橱柜的使用寿命。And the embedded microwave oven in the prior art depends on the gap between the fuselage and the cabinet to take in or out the air, so when the microwave heating function is used, the water vapor discharged from the cavity will enter the cabinet, which will cause certain damage to the cabinet , Affect the service life of the cabinet.

现有技术中的嵌入式微波烤箱通常由控制盒与门体间的间隙出风，导致控制盒位置有热风吹出，影响用户使用产品的感受。而本方案提供的嵌入式微波烤箱由控制盒与门体的间隙进风，由壳体前板的底端出风，使出风位置远离控制盒，以保证用户对控制盒进行操作时不会接触到热风，从而提升用户的使用感受。The built-in microwave oven in the prior art usually emits air from the gap between the control box and the door body, causing hot air to blow out from the position of the control box, which affects the user's experience of using the product. The built-in microwave oven provided by this solution enters the air from the gap between the control box and the door body, and the air is discharged from the bottom of the front panel of the casing, so that the air outlet position is far away from the control box, so as to ensure that the user will not operate the control box. Exposure to hot air, thereby enhancing the user experience.
在上述任一技术方案中，优选地，所述进风通道内设有隔板，所述隔板将所述进风通道分隔成前部区域和后部区域，且所述隔板上设有通风孔，所述电器件包括电脑板、滤波板、磁控管和变压器，所述电脑板和所述滤波板安装在所述前部区域内，所述磁控管和所述变压器安装在所述后部区域内。In any of the above technical solutions, preferably, a partition is provided in the air inlet passage, and the partition divides the air inlet passage into a front area and a rear area, and the partition is provided with ventilation holes, the electrical components include a computer board, a filter board, a magnetron and a transformer, the computer board and the filter board are installed in the front area, and the magnetron and the transformer are installed in the in the rear area mentioned above.
产品使用过程中，磁控管和变压器会产生较多热量，而电脑板和滤波板对温升控制要求较高，出现温升超标的问题会影响产品运行的可靠性。为此本方案通过隔板将电脑板、滤波板与磁控管、变压器等发热部件隔开，将电脑板和滤波板安装在隔板之前的前部区域内，使电脑板和滤波板的位置靠近壳体进风口，通过刚刚吸入壳体内的低温空气对电脑板和滤波板降温，而磁控管、变压器等发热部件安装在隔板后的后部区域内，处于电脑板和滤波板的下风侧，同时在隔板格挡下，可大幅减少磁控管、变压器所在的后部区域向电脑板、滤波板所在的前部区域传递热量，因此可大幅降低电脑板、滤波板的温升，从而保证产品运行的可靠性。During the use of the product, the magnetron and transformer will generate a lot of heat, while the computer board and filter board have high requirements for temperature rise control, and the problem of excessive temperature rise will affect the reliability of the product operation. For this reason, this plan separates the computer board, filter board and magnetron, transformer and other heating components through the partition board, and installs the computer board and filter board in the front area before the partition board, so that the position of the computer board and filter board Close to the air inlet of the shell, the computer board and filter board are cooled by the low-temperature air just sucked into the shell, while the magnetron, transformer and other heat-generating components are installed in the rear area behind the partition, which is downwind of the computer board and filter board At the same time, under the shield of the partition board, the heat transfer from the rear area where the magnetron and transformer are located to the front area where the computer board and filter board are located can be greatly reduced, so the temperature rise of the computer board and filter board can be greatly reduced. So as to ensure the reliability of product operation.
在上述任一技术方案中，优选地，所述腔体内安装有上发热管，所述上发热管靠近所述腔体的顶部安装，且位于所述后部区域的下方。In any of the above technical solutions, preferably, an upper heating pipe is installed in the cavity, and the upper heating pipe is installed close to the top of the cavity and located below the rear area.
这样设计拉大了电脑板、滤波板与上发热管的距离，可减小上发热管所产生的热辐射对电脑板、滤波板的影响，从而可进一步降低电脑板、滤波板的温升，提升产品运行的可靠性。This design widens the distance between the computer board, filter board and the upper heating pipe, which can reduce the impact of the heat radiation generated by the upper heating pipe on the computer board and filter board, thereby further reducing the temperature rise of the computer board and filter board. Improve the reliability of product operation.
在上述任一技术方案中，优选地，所述冷却风机安装在所述前部区域内。In any of the above technical solutions, preferably, the cooling fan is installed in the front area.
现有产品通常采用冷却风机后置的结构，这样设计冷却风机和产品进风口的距离过大，以致产品进风口位置产生的负压较低，吸入空气量少，无法对电器件进行充分冷却。本方案中，冷却风机的位置靠近壳体进风口，大幅缩短了冷却风机和进风口的距离，从而可增大壳体进风口位置负压，提高进风量，进而提升产品的散热效果。Existing products usually adopt a rear cooling fan structure, so the distance between the cooling fan and the air inlet of the product is too large, so that the negative pressure generated at the air inlet of the product is low, the amount of air sucked is small, and the electrical components cannot be fully cooled. In this solution, the position of the cooling fan is close to the air inlet of the housing, which greatly shortens the distance between the cooling fan and the air inlet, thereby increasing the negative pressure at the air inlet of the housing, increasing the air intake, and improving the heat dissipation effect of the product.
在上述任一技术方案中，优选地，所述腔体顶板上设有腔体进风口、腔体出风口和开闭控制组件，所述开闭控制组件用于控制所述腔体进风口和腔体出风口开闭。In any of the above technical solutions, preferably, the top plate of the cavity is provided with a cavity air inlet, a cavity air outlet, and an opening and closing control assembly, and the opening and closing control assembly is used to control the cavity air inlet and the opening and closing control assembly.

When the baffle is in the closed position, the baffle simultaneously closes the cavity air inlet and the cavity air outlet, and when the baffle is in the open position, the baffle simultaneously avoids the The air inlet of the cavity and the air outlet of the cavity, so that the air inlet of the cavity and the air outlet of the cavity are opened simultaneously.
本方案中，电脑板能够控制双向电机正传或反转，使双向电机可带动挡板往复运动，当产品开启微波加热时，双向电机带动挡板运动至打开位置，使腔体进风口和腔体出风口同时敞开，对腔体进行通风，以排出腔体内的水蒸气；当产品开启热风或者烧烤加热时，双向电机带动挡板运动至打开位关闭位置，使挡板将腔体进风口和腔体出风口同时封闭，确保腔体内温度可较快的上升，从而提升产品的加热效率。In this solution, the computer board can control the two-way motor to run forward or reverse, so that the two-way motor can drive the baffle to reciprocate. The air outlet of the body is opened at the same time to ventilate the cavity to discharge the water vapor in the cavity; when the product is turned on for hot air or barbecue heating, the two-way motor drives the baffle to move to the open position and the closed position, so that the baffle connects the air inlet and the cavity The air outlet of the cavity is closed at the same time to ensure that the temperature in the cavity can rise quickly, thereby improving the heating efficiency of the product.
在上述任一技术方案中，优选地，开闭控制组件还包括齿轮和齿条，所述齿轮固定安装在所述双向电机的电机轴上，所述齿条固定安装在所述挡板上，且所述齿条始终与所述齿轮啮合。In any of the above technical solutions, preferably, the opening and closing control assembly further includes a gear and a rack, the gear is fixedly mounted on the motor shaft of the bidirectional motor, the rack is fixedly mounted on the baffle, And the rack is always in mesh with the gear.

本方案通过设置第一位置开关和第二位置开关来判断挡板是否已到达关闭位置或打开位置，产品开启微波加热时，双向电机在电脑板控制下带动挡板运动向一侧运动，当挡板到达打开位置时，挡板与第二位置开关抵触，触发第二位置开关，使第二位置开关向电脑板发送触发信号，电脑板根据触发信号控制双向电机停转，从而将挡板保持在打开位置，使腔体进风口和腔体出风口同时打开。产品关闭微波加热时，双向电机在电脑板控制下带动挡板运动向反方向运动，当挡板到达关闭位置，挡板与第一位置开关抵触，触发第一位置开关，使第一位置开关向电脑板发送触发信号，电脑板根据触发信号控制双向电机停转，从而将挡板保持在关闭位置，使腔体进风口和腔体出风口同时关闭。This program judges whether the baffle has reached the closed position or the open position by setting the first position switch and the second position switch. When the product starts microwave heating, the two-way motor drives the baffle to move to one side under the control of the computer board. When the panel reaches the open position, the baffle will conflict with the second position switch, triggering the second position switch, so that the second position switch sends a trigger signal to the computer board, and the computer board controls the two-way motor to stop according to the trigger signal, thereby keeping the baffle at the In the open position, the cavity air inlet and the cavity air outlet are opened at the same time. When the microwave heating of the product is turned off, the two-way motor drives the baffle to move in the opposite direction under the control of the computer board. The computer board sends a trigger signal, and the computer board controls the two-way motor to stop rotating according to the trigger signal, thereby keeping the baffle at the closed position, so that the cavity air inlet and the cavity air outlet are simultaneously closed.
在上述任一技术方案中，优选地，所述腔体顶板包括顶板本体和支撑板，所述顶板本体与所述壳体前板、所述腔体后板、所述两个腔体侧板密封连接，所述支撑板安装在所述顶板本体的上表面上，所述支撑板和所述壳体顶板间形成所述进风通道。In any of the above technical solutions, preferably, the cavity top plate includes a top plate body and a support plate, and the top plate body is connected to the housing front plate, the cavity rear plate, and the two cavity side plates Sealed connection, the support plate is installed on the upper surface of the top plate body, and the air inlet channel is formed between the support plate and the housing top plate.
在上述任一技术方案中，优选地，所述腔体出风口包括设于所述顶板本体上的第一出风口和设于所述支撑板上并与所述第一出风口相对的第二出风口，所述腔体进风口包括设于所述顶板本体上的第一进风口和设于所述支撑板上的第二进风口，所述顶板本体和所述支撑板间设有连通所述第一进风口和所述第二进风口的腔体进风道，所述挡板能够控制所述第二进风口和所述第二出风口的开闭，其中，所述第一进风口靠近所述壳体前板，所述第二进风口和所述第二出风口位于所述后部区域内。In any of the above technical solutions, preferably, the air outlet of the cavity includes a first air outlet arranged on the top plate body and a second air outlet arranged on the support plate and opposite to the first air outlet. The air outlet, the air inlet of the cavity includes a first air inlet on the top body and a second air inlet on the support plate, and a communication station is provided between the top body and the support plate. The first air inlet and the cavity air inlet of the second air inlet, the baffle can control the opening and closing of the second air inlet and the second air outlet, wherein the first air inlet Adjacent to the housing front panel, the second air inlet and the second air outlet are located in the rear region.
产品开启微波加热时，挡板将支撑板上的第二进风口和第二出风口打开，进风通道内的部分空气由第二进风口进入支撑板和顶板本体间的腔体进风道内，然后沿腔体进风道到达第一进风口位置，接着由第一进风口进入腔体内，由于第一进风口靠近壳体前板，由第一进风口进入的空气会推动腔体的空气向腔体后端移动，最终依次穿过第一出风口和第二出风口进入冷却风道，这样可防止腔体内的水蒸气在门体内表面上凝结，从而保证门体视窗清晰可见，使用户能够看清腔体内的情况，且由于第一出风口和第二出风口位于后部区域内，因此腔体内排出的空气不会对电脑板和滤波板造成影响。When the product is turned on for microwave heating, the baffle opens the second air inlet and the second air outlet on the support plate, and part of the air in the air inlet channel enters the air inlet channel of the cavity between the support plate and the top plate body through the second air inlet. Then reach the position of the first air inlet along the air inlet channel of the cavity, and then enter the cavity from the first air inlet, because the first air inlet is close to the front plate of the housing, the air entering from the first air inlet will push the air in the cavity to The rear end of the cavity moves, and finally enters the cooling air passage through the first air outlet and the second air outlet in turn, which can prevent the water vapor in the cavity from condensing on the inner surface of the door, thereby ensuring that the window of the door body is clearly visible, so that users can The situation in the cavity can be seen clearly, and since the first air outlet and the second air outlet are located in the rear area, the air discharged from the cavity will not affect the computer board and filter board.
在上述任一技术方案中，优选地，所述后部区域内设有两个沿前后方向延伸的挡风板，所述磁控管、所述变压器和所述开闭控制组件均位于所述两个挡风板之间，且所述隔板的通气孔、所述第二进气口和所述第二出风口均对准所述两个挡风板之间的区域。In any of the above technical solutions, preferably, two windshields extending along the front and rear directions are arranged in the rear area, and the magnetron, the transformer and the switch control assembly are all located in the Between the two windshields, and the ventilation holes of the partition, the second air inlet and the second air outlet are all aligned with the area between the two windshields.
本方案在后部区域内间隔设置两个挡风板，且两个挡风板均沿前后方向延伸，这样设计减小了后部区域内的风道宽度，后部区域内的电器件均安装在两个挡风板，使空气集中流过电器件，从而可提升散热效果。In this scheme, two windshields are arranged at intervals in the rear area, and the two windshields extend along the front and rear directions. This design reduces the width of the air duct in the rear area, and the electrical components in the rear area In the two windshields, the air is concentrated to flow through the electrical components, thereby improving the heat dissipation effect.
在上述任一技术方案中，优选地，所述两个挡风板中的一个上设有向所述两挡风板之间凸出的挡风面，所述挡风面位于所述第二进风口的后方。In any of the above technical solutions, preferably, one of the two windshields is provided with a windshield protruding between the two windshields, and the windshield is located on the second behind the air intake.
通过挡风面阻挡空气流动可提升第二进风口的进风量，从而可提升腔体的通风效果，将腔体的水蒸气有效排出。Blocking the air flow through the windshield surface can increase the air intake volume of the second air inlet, thereby improving the ventilation effect of the cavity and effectively discharging the water vapor in the cavity.

嵌入式微波烤箱的腔体后方通常安装有热风组件，而现有产品的散热结构无法对热风电机进行有效散热，因此必须通过较厚的隔热材料包裹热风电机，且需要增加热风电机散热风扇，这样导致热风组件占用空间较大，为使产品满足规格，只能减小腔体的体积，以致产品容积受损。而本方案提供的嵌入式微波烤箱的冷却风道穿过腔体后板和壳体后罩的间隙，而热风电机安装在腔体后板和壳体后罩的间隙内，可有效降低转盘电机的温度，因此可减小热风电机隔热层的厚度并去除热风电机散热风扇，从而可增大腔体的体积，提升产品的容积。A hot air component is usually installed behind the cavity of the embedded microwave oven, but the heat dissipation structure of the existing products cannot effectively dissipate heat from the hot air motor, so the hot air motor must be wrapped with a thicker heat insulating material, and the cooling fan of the hot air motor needs to be added. This causes the hot air component to take up a large space. In order to make the product meet the specifications, the volume of the cavity can only be reduced, so that the volume of the product is damaged. The cooling air passage of the embedded microwave oven provided by this solution passes through the gap between the cavity rear plate and the housing rear cover, and the hot air motor is installed in the gap between the cavity rear plate and the housing rear cover, which can effectively reduce the temperature of the turntable motor. Therefore, the thickness of the thermal insulation layer of the hot air motor can be reduced and the cooling fan of the hot air motor can be removed, thereby increasing the volume of the cavity and increasing the volume of the product.

在腔体内的底部安装有下发热管时，下发热管产生的热辐射对转盘电机影响较大，现有产品无法对转盘电机进行有效散热。而本方案提供的嵌入式微波烤箱的冷却风道穿过腔体底板和壳体底板的间隙，而转盘电机安装在腔体底板和壳体底板的间隙内，因此可有效降低转盘电机的温度。When the lower heating tube is installed at the bottom of the cavity, the heat radiation generated by the lower heating tube has a greater impact on the turntable motor, and the existing products cannot effectively dissipate heat from the turntable motor. The cooling air duct of the embedded microwave oven provided by this solution passes through the gap between the bottom plate of the cavity and the bottom plate of the shell, and the turntable motor is installed in the gap between the bottom plate of the cavity and the bottom plate of the shell, so the temperature of the turntable motor can be effectively reduced.
在上述任一技术方案中，优选地，所述两个腔体侧板和所述两个壳体侧板间分别形成与所述下出风通道的侧出风通道，所述壳体出风口还包括位于所述壳体前板左右两端并与所述侧出风通道连通的侧出风口。In any of the above technical solutions, preferably, side air outlet passages with the lower air outlet passage are respectively formed between the two cavity side plates and the two housing side plates, and the air outlet of the housing It also includes side air outlets located at the left and right ends of the front panel of the housing and communicating with the side air outlet passage.
本方案在下出风的基础上，在壳体前板两侧开设侧出风口，通过壳体增加两侧在壳体前板两侧出风通道，这样设计较大了产品冷却风道的覆盖范围，同时提升了出风效果，从而可提升产品整体的散热效果。On the basis of the bottom air outlet, this solution sets up side air outlets on both sides of the front panel of the housing, and increases the air outlet channels on both sides of the front panel of the housing through the housing. This design increases the coverage of the product cooling air duct. , At the same time, the air outlet effect is improved, so as to improve the overall heat dissipation effect of the product.
在上述任一技术方案中，优选地，所述嵌入式微波烤箱还包括：三个导风板，所述三个导风板分别安装在所述壳体底板和所述两个壳体侧板的前端，且所述三个导风板均延伸至所述壳体前板前方，以使三个导风板分别处于所述下出风口和所述侧出风口的外侧。In any of the above technical solutions, preferably, the embedded microwave oven further includes: three air deflectors, and the three air deflectors are respectively installed on the bottom plate of the housing and the two side plates of the housing and the three wind deflectors all extend to the front of the housing front panel, so that the three wind deflectors are respectively located outside the lower air outlet and the side air outlet.
导风板位于腔体出风口的外侧，避免由腔体出风口排出的空气与橱柜接触，以防止排气中的水分对橱柜造成损害。The air deflector is located outside the air outlet of the cavity to prevent the air discharged from the air outlet of the cavity from contacting the cabinet, so as to prevent the moisture in the exhaust from causing damage to the cabinet.

However, the present invention can also be implemented in other ways than described here. Therefore, the protection scope of the present invention is not limited by the specific implementation disclosed below. Example limitations.

There are housing air inlets 1011 and housing air outlets communicating with the cooling air duct; the cooling fan 301 is installed in the cooling air duct. The air is sucked from the air inlet 1011 of the housing and sent to the air outlet of the housing through the cooling air duct; the electrical components are installed in the cooling air duct.
本方案中，嵌入式微波烤箱的壳体和腔体间形成冷却风道，壳体进风口1011和壳体出风口都开设在壳体前板101上，这样设计冷却风道完全处于产品内部，进出风不受橱柜尺寸影响，散热稳定可靠，即使在橱柜尺寸达不到设计要求时，也可实现良好的散热效果，防止出现电器件温升超标的问题，从而保证产品可运行的安全性和稳定性。In this solution, a cooling air passage is formed between the shell and the cavity of the embedded microwave oven, and the air inlet 1011 of the shell and the air outlet of the shell are both set on the front plate 101 of the shell, so that the cooling air duct is designed to be completely inside the product. The air in and out is not affected by the size of the cabinet, and the heat dissipation is stable and reliable. Even when the size of the cabinet does not meet the design requirements, a good heat dissipation effect can be achieved to prevent the problem of excessive temperature rise of electrical components, thereby ensuring the safety and reliability of the product. stability.
其中，腔体顶板上设有腔体进风口、腔体出风口和开闭控制组件，开闭控制组件用于控制腔体进风口和腔体出风口开闭。现有技术中的嵌入式微波烤箱依赖机身和橱柜间的间隙进风或出风，在使用微波加热功能时，仅能控制腔体进风口开关，不能控制腔体出风口开关，为保证腔体中心温度迅速上升，必须控制腔体出风口数量，造成腔体内水蒸气无法散发，水蒸气会通过腔体缝隙以及热风组件装配缝隙流入橱柜，对橱柜造成一定损害，影响橱柜的使用寿命。而本方案提供的嵌入式微波烤箱的冷却风道完全处于产品内，由壳体前板101出风，以保证腔体内排出的水蒸气不会与橱柜内部接触，避免对橱柜造成损害，从而可延长橱柜的使用寿命。Wherein, the air inlet of the chamber, the air outlet of the chamber and the opening and closing control assembly are arranged on the top plate of the chamber, and the opening and closing control assembly is used to control the opening and closing of the air inlet of the chamber and the air outlet of the chamber. The embedded microwave oven in the prior art relies on the gap between the fuselage and the cabinet to take in or out the air. When using the microwave heating function, it can only control the switch of the air inlet of the cavity, but not the switch of the air outlet of the cavity. The temperature of the body center rises rapidly, and the number of air outlets in the cavity must be controlled, so that the water vapor in the cavity cannot be released. The water vapor will flow into the cabinet through the gaps in the cavity and the assembly gap of the hot air component, causing certain damage to the cabinet and affecting the service life of the cabinet. However, the cooling air duct of the embedded microwave oven provided by this solution is completely inside the product, and the air is discharged from the front panel 101 of the housing to ensure that the water vapor discharged from the cavity will not contact the inside of the cabinet and avoid damage to the cabinet, so that it can Extend the life of your cabinets.
具体地，腔体顶板与壳体顶板102间形成进风通道，腔体后板203与壳体后罩103间形成导风通道，腔体底板204与壳体底板104间形成下出风通道，进风通道、导风通道和下出风通道依次连通构成冷却风道，控制盒107位于门体106的上方，且控制盒107与门体106间形成间隙，壳体进风口1011对准控制盒107和门体106间的间隙并与进风通道连通，壳体出风口包括壳体下出风口1012，壳体下出风口1012位于门体106下方并与下出风通道连通。Specifically, an air inlet channel is formed between the cavity top plate and the housing top plate 102, an air guide channel is formed between the cavity rear plate 203 and the housing rear cover 103, and a lower air outlet channel is formed between the cavity bottom plate 204 and the housing bottom plate 104. The air inlet channel, the air guide channel and the lower air outlet channel are connected in turn to form a cooling air channel. The control box 107 is located above the door body 106, and a gap is formed between the control box 107 and the door body 106. The air inlet 1011 of the housing is aligned with the control box. The gap between 107 and the door body 106 communicates with the air inlet passage, and the air outlet of the casing includes the lower air outlet 1012 of the casing. The lower air outlet 1012 of the casing is located below the door body 106 and communicates with the lower air outlet passage.
现有技术中的嵌入式微波烤箱通常由控制盒与门体间的间隙出风，导致控制盒位置有热风吹出，影响用户使用产品的感受。而本方案提供的嵌入式微波烤箱由控制盒107与门体106的间隙进风，由壳体前板101的底端出风，使出风位置远离控制盒107，以保证用户对控制盒107进行操作时不会接触到热风，从而提升用户的使用感受。The built-in microwave oven in the prior art usually emits air from the gap between the control box and the door body, causing hot air to blow out from the position of the control box, which affects the user's experience of using the product. The built-in microwave oven provided by this program enters the air from the gap between the control box 107 and the door body 106, and the air is discharged from the bottom of the front panel 101 of the housing, so that the position of the air outlet is far away from the control box 107, so as to ensure that the user has a good understanding of the control box 107. It will not be exposed to hot air during operation, thereby improving the user experience.
在上述实施例中，进风通道内设有隔板701，隔板701将进风通道分隔成前部区域和后部区域，且隔板701上设有通风孔，电器件包括电脑板402、滤波板403、磁控管404和变压器405，电脑板402和滤波板403安装在前部区域内，磁控管404和变压器405安装在后部区域内。In the above-mentioned embodiment, a partition 701 is provided in the air inlet passage, and the partition 701 divides the air inlet passage into a front area and a rear area, and the partition 701 is provided with ventilation holes, and the electrical components include a computer board 402, Filter board 403, magnetron 404 and transformer 405, computer board 402 and filter board 403 are installed in the front area, magnetron 404 and transformer 405 are installed in the rear area.
产品使用过程中，磁控管404和变压器405会产生较多热量，而电脑板402和滤波板403对温升控制要求较高，出现温升超标的问题会影响产品运行的可靠性。为此本方案通过隔板701将电脑板402、滤波板403与磁控管404、变压器405等发热部件隔开，将电脑板402和滤波板403安装在隔板701之前的前部区域内，使电脑板402和滤波板403的位置靠近壳体进风口1011，通过刚刚吸入壳体内的低温空气对电脑板402和滤波板403降温，而磁控管404、变压器405等发热部件安装在隔板701后的后部区域内，处于电脑板402和滤波板403的下风侧，同时在隔板701格挡下，可大幅减少磁控管404、变压器405所在的后部区域向电脑板402、滤波板403所在的前部区域传递热量，因此可大幅降低电脑板402、滤波板403的温升，从而保证产品运行的可靠性。During the use of the product, the magnetron 404 and the transformer 405 will generate a lot of heat, while the computer board 402 and the filter board 403 have high requirements for temperature rise control, and the problem of excessive temperature rise will affect the reliability of the product operation. For this reason, this program separates the computer board 402, the filter board 403 from heating components such as the magnetron 404 and the transformer 405 by the partition board 701, and the computer board 402 and the filter board 403 are installed in the front region before the partition board 701, The position of the computer board 402 and the filter board 403 is close to the air inlet 1011 of the housing, and the temperature of the computer board 402 and the filter board 403 is cooled by the low-temperature air just sucked into the housing, while the magnetron 404, the transformer 405 and other heating components are installed on the partition In the rear area behind 701, it is on the leeward side of the computer board 402 and the filter board 403. At the same time, under the shield of the partition plate 701, the impact of the magnetron 404 and the transformer 405 on the rear area where the magnetron 404 and transformer 405 are located can be greatly reduced. The front area where the board 403 is located transfers heat, so the temperature rise of the computer board 402 and the filter board 403 can be greatly reduced, thereby ensuring the reliability of product operation.
在上述实施例中，腔体内安装有上发热管601，上发热管601靠近腔体的顶部安装，且位于后部区域的下方。In the above embodiment, the upper heating tube 601 is installed in the cavity, and the upper heating tube 601 is installed near the top of the cavity and is located below the rear area.
这样设计拉大了电脑板402、滤波板403与上发热管601的距离，可减小上发热管601所产生的热辐射对电脑板402、滤波板403的影响，从而可进一步降低电脑板402、滤波板403的温升，提升产品运行的可靠性。This design widens the distance between the computer board 402, the filter board 403 and the upper heat pipe 601, which can reduce the impact of the heat radiation produced by the upper heat pipe 601 on the computer board 402 and the filter board 403, thereby further reducing the temperature of the computer board 402. 1. The temperature rise of the filter board 403 improves the reliability of product operation.
在上述实施例中，冷却风机301安装在前部区域内。In the above-described embodiments, the cooling fan 301 is installed in the front area.
现有产品通常采用冷却风机后置的结构，这样设计冷却风机和产品进风口的距离过大，以致产品进风口位置产生的负压较低，吸入空气量少，无法对电器件进行充分冷却。本方案中，冷却风机301的位置靠近壳体进风口1011，大幅缩短了冷却风机301和进风口的距离，从而可增大壳体进风口1011位置负压，提高进风量，进而提升产品的散热效果。Existing products usually adopt a rear cooling fan structure, so the distance between the cooling fan and the air inlet of the product is too large, so that the negative pressure generated at the air inlet of the product is low, the amount of air sucked is small, and the electrical components cannot be fully cooled. In this solution, the position of the cooling fan 301 is close to the air inlet 1011 of the housing, which greatly shortens the distance between the cooling fan 301 and the air inlet, thereby increasing the negative pressure at the air inlet 1011 of the housing, increasing the air intake, and further improving the heat dissipation of the product Effect.
在上述实施例中，优选地，两个腔体侧壁205和两个壳体侧板105间分别形成与下出风通道的侧出风通道，壳体出风口还包括与侧出风通道连通的侧出风口1013，侧出风口1013设置在壳体前板101上且位于门体106左右两侧。In the above embodiment, preferably, the two side walls 205 of the cavity and the two side plates 105 of the housing form a side air outlet channel with the lower air outlet channel, and the air outlet of the housing also includes a channel connected to the side air outlet channel. The side air outlets 1013 are provided on the front panel 101 of the housing and located on the left and right sides of the door body 106 .
本方案在下出风的基础上，在壳体前板101两侧开设侧出风口1013，通过壳体增加两侧在壳体前板101两侧出风通道，这样设计较大了产品冷却风道的覆盖范围，同时提升了出风效果，从而可提升产品整体的散热效果。In this solution, on the basis of the lower air outlet, side air outlets 1013 are set on both sides of the front panel 101 of the housing, and the air outlet channels on both sides of the front panel 101 of the housing are increased through the housing, so that the design of the product cooling air duct is larger coverage, while improving the wind effect, which can improve the overall cooling effect of the product.
具体地，腔体顶板包括顶板本体201和支撑板202，顶板本体201与壳体前板101、腔体后板203、两个腔体侧壁205密封连接，支撑板202安装在顶板本体201的上表面上，支撑板202和壳体顶板102间形成进风通道。腔体出风口包括设于顶板本体201上的第一出风口2012和设于支撑板202上并与第一出风口2012相对的第二出风口2022，腔体进风口包括设于顶板本体201上的第一进风口2011和设于支撑板202上的第二进风口2021，且第二进风口2021与第二出风口2022并排设置，顶板本体201和支撑板202间设有连通第一进风口2011和第二进风口2021的腔体进风道2013，挡板501能够控制第二进风口2021和第二出风口2022的开闭，其中，第一进风口2011靠近壳体前板101，第二进风口2021和第二出风口2022位于后部区域内。开闭控制组件包括双向电机502、挡板501、齿轮503、齿条504、第一位置开关505和第二位置开关506，双向电机502与电脑板402电连接，齿轮503固定安装在双向电机502的电机轴上，齿条504固定安装在挡板501上，且齿条504始终与齿轮503啮合，以使双向电机502能够带动挡板501沿第二进风口2021和第二出风口2022的连线方向往复运动，挡板501大致呈矩形，且挡板501上设有与第二出风口2022适配的缺口5011，第一位置开关505和第二位置开关506分别与电脑板402电连接，挡板501相对腔体顶板具有关闭位置和打开位置，挡板501处于关闭位置时，挡板501同时将第二进风口2021和第二出风口2022封闭，且挡板501到达关闭位置时与第一位置开关505抵触，以触发第一位置开关505，挡板501处于打开位置时，挡板501错开第二进风口2021，且挡板501上的缺口5011与第二出风口2022对齐，以使腔体进风口和腔体出风口同时敞开，并且挡板501到达打开位置时与第二位置开关506抵触，以触发第二位置开关506。Specifically, the cavity top plate includes a top plate body 201 and a support plate 202, the top plate body 201 is in sealing connection with the housing front plate 101, the cavity rear plate 203, and two cavity side walls 205, and the support plate 202 is installed on the top plate body 201. On the upper surface, an air inlet channel is formed between the support plate 202 and the top plate 102 of the casing. The cavity air outlet includes a first air outlet 2012 on the top plate body 201 and a second air outlet 2022 on the support plate 202 opposite to the first air outlet 2012. The first air inlet 2011 and the second air inlet 2021 on the support plate 202, and the second air inlet 2021 and the second air outlet 2022 are arranged side by side, and the first air inlet connected between the top plate body 201 and the support plate 202 2011 and the cavity air inlet 2013 of the second air inlet 2021, the baffle 501 can control the opening and closing of the second air inlet 2021 and the second air outlet 2022, wherein the first air inlet 2011 is close to the front panel 101 of the housing, the second The second air inlet 2021 and the second air outlet 2022 are located in the rear area. The opening and closing control assembly includes a bidirectional motor 502, a baffle plate 501, a gear 503, a rack 504, a first position switch 505 and a second position switch 506, the bidirectional motor 502 is electrically connected with the computer board 402, and the gear 503 is fixedly mounted on the bidirectional motor 502. On the motor shaft, the rack 504 is fixedly installed on the baffle 501, and the rack 504 is always engaged with the gear 503, so that the bidirectional motor 502 can drive the baffle 501 along the connection between the second air inlet 2021 and the second air outlet 2022. The baffle 501 is roughly rectangular, and the baffle 501 is provided with a gap 5011 adapted to the second air outlet 2022. The first position switch 505 and the second position switch 506 are respectively electrically connected to the computer board 402. The baffle plate 501 has a closed position and an open position relative to the cavity ceiling. When the baffle plate 501 is in the closed position, the baffle plate 501 simultaneously closes the second air inlet 2021 and the second air outlet 2022, and when the baffle plate 501 reaches the closed position, it is in contact with the second air outlet 2022. A position switch 505 conflicts to trigger the first position switch 505. When the baffle 501 is in the open position, the baffle 501 is staggered away from the second air inlet 2021, and the notch 5011 on the baffle 501 is aligned with the second air outlet 2022, so that The cavity air inlet and the cavity air outlet are opened at the same time, and when the baffle 501 reaches the open position, it interferes with the second position switch 506 to trigger the second position switch 506 .
产品开启微波加热时，如图5和图6所示，双向电机502在电脑板402控制下带动挡板501运动向一侧运动，当挡板501到达打开位置时，挡板501与第二位置开关506抵触，触发第二位置开关506，使第二位置开关506向电脑板402发送触发信号，电脑板402根据触发信号控制双向电机502停转，从而将挡板501保持在打开位置，使腔体进风口和腔体出风口同时打开。在散热电机作用下，外部空气由壳体进风口1011进入进风通道，为进风通道内电器件降温，进风通道内的部分空气由第二进风口2021进入支撑板202和顶板本体201间的腔体进风道2013内，然后沿腔体进风道2013到达第一进风口2011位置，接着由第一进风口2011进入腔体内，由于第一进风口2011靠近壳体前板101，由第一进风口2011进入的空气会推动腔体的空气向腔体后端移动，最终依次穿过第一出风口2012和第二出风口2022进入冷却风道，这样可防止腔体内的水蒸气在门体106内表面上凝结，从而保证门体106视窗清晰可见，使用户能够看清腔体内的情况，且由于第一出风口2012和第二出风口2022位于后部区域内，因此腔体内排出的空气不会对电脑板402和滤波板403造成影响。而进风通道内未进入第二进风口2021那一部风空气和由第二出风口2022回到进风通道内的空气都会进入导风通道，然后再由导风通道进入下出风通道和侧出风通道，最终由壳体前板101上下出风口1012和侧出风口1013排出产品外。When the product is turned on for microwave heating, as shown in Figure 5 and Figure 6, the bidirectional motor 502 drives the baffle 501 to move to one side under the control of the computer board 402, and when the baffle 501 reaches the open position, the baffle 501 and the second position The switch 506 is in conflict, triggering the second position switch 506, so that the second position switch 506 sends a trigger signal to the computer board 402, and the computer board 402 controls the two-way motor 502 to stop according to the trigger signal, thereby keeping the baffle plate 501 in the open position and making the cavity The air inlet of the body and the air outlet of the cavity are opened at the same time. Under the action of the heat dissipation motor, the external air enters the air inlet channel from the air inlet 1011 of the casing to cool down the electrical components in the air inlet channel, and part of the air in the air inlet channel enters the space between the support plate 202 and the top plate body 201 through the second air inlet 2021 into the cavity air inlet duct 2013, then along the cavity air inlet duct 2013 to the position of the first air inlet 2011, and then enter the cavity through the first air inlet 2011, because the first air inlet 2011 is close to the front panel 101 of the housing, by The air entering the first air inlet 2011 will push the air in the cavity to move to the rear end of the cavity, and finally pass through the first air outlet 2012 and the second air outlet 2022 into the cooling air passage, which can prevent the water vapor in the cavity Condensation on the inner surface of the door body 106 ensures that the window of the door body 106 is clearly visible, so that the user can see the situation in the cavity clearly, and since the first air outlet 2012 and the second air outlet 2022 are located in the rear area, the air is discharged from the cavity The air in the air will not affect the computer board 402 and the filter board 403. And the air that does not enter the second air inlet 2021 in the air inlet channel and the air that returns to the air inlet channel by the second air outlet 2022 will enter the air guide channel, and then enter the lower air outlet channel and the air guide channel by the air guide channel. The side air outlet channel finally discharges the product from the upper and lower air outlets 1012 and side air outlets 1013 of the front panel 101 of the housing.
产品关闭微波加热时，如图7和图8所示，双向电机502在电脑板402控制下带动挡板501运动向反方向运动，当挡板501到达关闭位置，挡板501与第一位置开关505抵触，触发第一位置开关505，使第一位置开关505向电脑板402发送触发信号，电脑板402根据触发信号控制双向电机502停转，从而将挡板501保持在关闭位置，使第二进风口2021和第二出风口2022同时关闭。在散热电机作用下，外部空气由壳体进风口1011进入进风通道，为进风通道内电器件降温，接着由进风通道进入导风通道，然后再由导风通道进入下出风通道和侧出风通道，最终由壳体前板101上下出风口1012和侧出风口1013排出产品外。When the microwave heating of the product is turned off, as shown in Figure 7 and Figure 8, the two-way motor 502 drives the baffle 501 to move in the opposite direction under the control of the computer board 402. When the baffle 501 reaches the closed position, the baffle 501 and the first position switch 505 conflicts, triggering the first position switch 505, so that the first position switch 505 sends a trigger signal to the computer board 402, and the computer board 402 controls the two-way motor 502 to stop according to the trigger signal, thereby keeping the baffle plate 501 in the closed position, so that the second The air inlet 2021 and the second air outlet 2022 are closed simultaneously. Under the action of the heat dissipation motor, the external air enters the air inlet channel from the air inlet 1011 of the housing to cool down the electrical components in the air inlet channel, and then enters the air guide channel from the air inlet channel, and then enters the lower air outlet channel and the air guide channel from the air guide channel. The side air outlet channel finally discharges the product from the upper and lower air outlets 1012 and side air outlets 1013 of the front panel 101 of the housing.
在上述实施例中，后部区域内设有两个沿前后方向延伸的挡风板702，磁控管404、变压器405和开闭控制组件均位于两个挡风板702之间，且隔板701的通气孔、第二进气口和第二出风口2022均对准两个挡风板702之间的区域。In the above-mentioned embodiment, there are two windshields 702 extending in the front and rear directions in the rear area, the magnetron 404, the transformer 405 and the switch control assembly are all located between the two windshields 702, and the partition The ventilation holes of 701 , the second air inlet and the second air outlet 2022 are all aligned with the area between the two windshields 702 .
本方案在后部区域内间隔设置两个挡风板702，且两个挡风板702均沿前后方向延伸，这样设计减小了后部区域内的风道宽度，后部区域内的电器件均安装在两个挡风板702，使空气集中流过电器件，从而可提升散热效果。In this scheme, two windshields 702 are arranged at intervals in the rear area, and the two windshields 702 extend along the front and rear directions. This design reduces the width of the air duct in the rear area, and the electrical components in the rear area Both are installed on the two windshields 702, so that the air flows through the electrical components in a concentrated manner, thereby improving the heat dissipation effect.
在上述实施例中，两个挡风板702中的一个上设有向两挡风板702之间凸出的挡风面，挡风面位于第二进风口2021的后方。In the above embodiment, one of the two windshields 702 is provided with a windshield protruding between the two windshields 702 , and the windshield is located behind the second air inlet 2021 .
通过挡风面阻挡空气流动可提升第二进风口2021的进风量，从而可提升腔体的通风效果，将腔体的水蒸气有效排出。Blocking the air flow through the windshield surface can increase the air intake volume of the second air inlet 2021, thereby improving the ventilation effect of the cavity and effectively discharging the water vapor in the cavity.
在上述实施例中，电器件还包括热风电机401，热风电机401安装在导风通道内。In the above embodiment, the electrical device further includes a hot air motor 401 installed in the air guide channel.
嵌入式微波烤箱的腔体后方通常安装有热风组件，而现有产品的散热结构无法对热风电机进行有效散热，因此必须通过较厚的隔热材料包裹热风电机，且需要增加热风电机散热风扇，这样导致热风组件占用空间较大，为使产品满足规格，只能减小腔体的体积，以致产品容积受损。而本方案提供的嵌入式微波烤箱的冷却风道穿过腔体后板203和壳体后罩103的间隙，而热风电机401安装在腔体后板203和壳体后罩103的间隙内，可有效降低转盘电机406的温度，因此可减小热风电机401隔热层的厚度并去除热风电机401散热风扇，从而可增大腔体的体积，提升产品的容积。A hot air component is usually installed behind the cavity of the embedded microwave oven, but the heat dissipation structure of the existing products cannot effectively dissipate heat from the hot air motor, so the hot air motor must be wrapped with a thicker heat insulating material, and the cooling fan of the hot air motor needs to be added. This causes the hot air component to take up a large space. In order to make the product meet the specifications, the volume of the cavity can only be reduced, so that the volume of the product is damaged. However, the cooling air passage of the embedded microwave oven provided by this solution passes through the gap between the cavity rear plate 203 and the housing rear cover 103, and the hot air motor 401 is installed in the gap between the cavity rear plate 203 and the housing rear cover 103, The temperature of the turntable motor 406 can be effectively reduced, so the thickness of the heat insulation layer of the hot air motor 401 can be reduced and the cooling fan of the hot air motor 401 can be removed, thereby increasing the volume of the cavity and improving the volume of the product.
在上述实施例中，电器件还包括转盘电机406，转盘电机406安装在出风通道内。In the above embodiment, the electrical device further includes a turntable motor 406, and the turntable motor 406 is installed in the air outlet channel.
在腔体内的底部安装有下发热管时，下发热管产生的热辐射对转盘电机406影响较大，现有产品无法对转盘电机406进行有效散热。而本方案提供的嵌入式微波烤箱的冷却风道穿过腔体底板204和壳体底板104的间隙，而转盘电机406安装在腔体底板204和壳体底板104的间隙内，因此可有效降低转盘电机406的温度。When the lower heating tube is installed at the bottom of the cavity, the heat radiation generated by the lower heating tube has a greater impact on the turntable motor 406 , and the existing products cannot effectively dissipate heat from the turntable motor 406 . However, the cooling air duct of the embedded microwave oven provided by this solution passes through the gap between the cavity bottom plate 204 and the shell bottom plate 104, and the turntable motor 406 is installed in the gap between the cavity bottom plate 204 and the shell bottom plate 104, so it can effectively reduce the The temperature of the turntable motor 406.
在上述实施例中，嵌入式微波烤箱还包括：三个导风板703，三个导风板703分别安装在壳体底板104和两个壳体侧板105的前端，且三个导风板703均延伸至壳体前板101前方，以使三个导风板703分别处于下出风口1012和侧出风口1013的外侧。In the above-mentioned embodiment, the embedded microwave oven further includes: three wind deflectors 703, the three wind deflectors 703 are installed on the front end of the shell bottom plate 104 and the two shell side plates 105 respectively, and the three wind deflectors 703 all extend to the front of the front panel 101 of the casing, so that the three air deflectors 703 are located outside the lower air outlet 1012 and the side air outlet 1013 respectively.
导风板703位于腔体出风口的外侧，避免由腔体出风口排出的空气与橱柜接触，以防止排气中的水分对橱柜造成损害。The air deflector 703 is located outside the air outlet of the cavity to prevent the air discharged from the air outlet of the cavity from contacting the cabinet, so as to prevent the moisture in the exhaust from causing damage to the cabinet.
