技术领域technical field
本实用新型涉及家电技术领域，特别涉及一种加热烹调装置。The utility model relates to the technical field of household appliances, in particular to a heating and cooking device.
背景技术Background technique
微波烤箱可通过两种模式对放置其腔体内的食物进行加热，一个是微波加热模式，微波烤箱产生的微波对腔体内的食物进行加热，一个是烘烤模式，微波烤箱内的热风组件产生热量对腔体内的食物进行烘烤。因此微波烤箱使用上十分便利，微波烤箱也属于欧美常用的家用电器，其用于加热披萨、解冻、烘烤整鸡等操作。The microwave oven can heat the food placed in its cavity through two modes, one is the microwave heating mode, the microwave generated by the microwave oven heats the food in the cavity, and the other is the baking mode, the hot air component in the microwave oven generates heat The food in the cavity is toasted. Therefore, microwave ovens are very convenient to use. Microwave ovens are also commonly used household appliances in Europe and the United States. They are used for heating pizza, thawing, and roasting whole chickens.
微波烤箱在上述的两种工作模式中，在微波加热模式时，因某些微波加热的食物会产生较多的水蒸气，需要向腔体内输入流动空气将水蒸气带走，而在烘烤模式时，微波烤箱以热风组件产生的热风对食物进行加热，因此在此模式下腔体内不适合输入过多的流动空气。In the above two working modes of the microwave oven, in the microwave heating mode, because some microwave-heated foods will generate more water vapor, it is necessary to input flowing air into the cavity to take away the water vapor, while in the baking mode In this mode, the microwave oven heats the food with the hot air generated by the hot air component, so it is not suitable to input too much flowing air into the cavity in this mode.
现有的微波烤箱因缺乏对输入腔体风量控制，使得微波烤箱在烘烤模式时，腔体内部温度提升缓慢，而在微波加热模式时，腔体内部积水较多。Due to the lack of control of the air volume input into the cavity of the existing microwave oven, the temperature inside the cavity increases slowly when the microwave oven is in the baking mode, and there is a lot of water in the cavity when the microwave oven is in the heating mode.

The second position of this embodiment corresponds to the microwave heating mode of the microwave oven. In the microwave heating mode, the motor 32 drives the wind deflector 31 to rotate to be in the second position. At this time, the first baffle 311 blocks the air outlet of the air duct 13 132, the plane where the first baffle 311 is located and the plane where the air outlet 132 is located form an acute angle, preferably 45° in this embodiment, most of the wind in the air duct 13 flows along the second baffle 312 and enters the cavity through the air inlet 211 of the cavity 20 , the mixed gas with oil fume and water vapor generated during the microwave heating process of the food in the cavity 20 is discharged from the cavity 20 . In the above two working modes of the microwave oven, the air flowing out from the air outlet 132 can dissipate the heat generated by the electronic components above the cavity 20 and reduce the temperature of some electronic components of the microwave oven.
请结合参照图4、图5及图9，第二挡板312靠近电机32的一端插接有凸块33，隔板112和罩体111之间形成有限位槽113，凸块33设于限位槽113内。Please refer to Fig. 4, Fig. 5 and Fig. 9 together, the end of the second baffle plate 312 close to the motor 32 is plugged with a protrusion 33, and a limiting groove 113 is formed between the partition plate 112 and the cover body 111, and the protrusion 33 is located at the limit Inside slot 113.
微波烤箱进行不同工作模式切换时，电机32驱动导风板31旋转过程中，通过凸块33和限位槽113的槽壁的抵接配合，使得导风板31能准确地停止于第一位置和第二位置。When the microwave oven switches between different working modes, the motor 32 drives the wind deflector 31 to rotate, and through the abutment and cooperation between the protrusion 33 and the groove wall of the limiting groove 113, the wind deflector 31 can accurately stop at the first position and second position.
该导风组件30还包括固定于所述罩体111的至少一个微动开关34(参图5和图9)，在导风板31转动过程中，凸块33抵接微动开关34。The wind deflector assembly 30 also includes at least one micro switch 34 (refer to FIG. 5 and FIG. 9 ) fixed on the cover 111 , and the protrusion 33 abuts against the micro switch 34 during the rotation of the wind deflector 31 .
本实施例微动开关34的数量为一个，导风板31通过凸块33和限位槽113的槽壁的抵接配合作用以及微动开关34对凸块33的检测的双重作用，实现导风板31能更精准的停止于第一位置和第二位置。于其他实施例中，也可在罩体111装设有两个微动开关34，其中一个对应烘烤模式的第一位置，另一个对应微波加热模式的第二位置，当凸块33触碰第一位置的微动开关34时，电机停止工作，导风板31停止于第一位置而进入烘烤模式；当凸块33触碰第二位置的微动开关34时，电机停止工作，导风板31停止于第二位置而进入微波加热模式。The number of the micro switch 34 in this embodiment is one, and the wind deflector 31 realizes the guide through the abutment and cooperation of the protrusion 33 and the groove wall of the limit groove 113 and the detection of the micro switch 34 on the protrusion 33. The wind plate 31 can stop at the first position and the second position more precisely. In other embodiments, two microswitches 34 can also be installed on the cover 111, one of which corresponds to the first position of the baking mode, and the other corresponds to the second position of the microwave heating mode, when the bump 33 touches When the microswitch 34 of the first position, the motor stops working, and the air deflector 31 stops at the first position and enters the baking mode; when the bump 33 touches the microswitch 34 of the second position, the motor stops working, and the guide The wind plate 31 stops at the second position and enters the microwave heating mode.
本实用新型微波烤箱实际工作中，微波烤箱接电后，无论导风板31初始位置在哪个角度，主控制器控制电机32进行自检，如在启动微波加热模式2秒后，因凸块33和限位槽113的配合限位作用，电机32具有转动最大角度限制，当凸块33已经抵接到限位槽113的槽壁而使电机32连续2秒不转动时，主控制器则控制电机32直接进行反转，最后导风板31在转动过程中，带动凸块33触碰到微动开关34的触点后，主控制器再命令电机32正转45°后停止，达到图4位置。在启动烘烤模式2秒后，主控制器控制电机32进行自检(电机32运动到最大角度时，因为有限位结构，当电机32连续2秒不转动时，电机32直接进行反转)，当导风板凸点触碰到微动开关34的触点后，主控制器再命令电机32停止工作，达到图1位置。所以，即使出现微波烤箱突然断电的情况，也不会使导风结构工作异常。In the actual work of the microwave oven of the present utility model, after the microwave oven is powered on, no matter which angle the initial position of the wind deflector 31 is, the main controller controls the motor 32 to perform a self-check. Cooperating with the limit groove 113, the motor 32 has a maximum rotation angle limit. When the bump 33 has abutted against the wall of the limit groove 113 and the motor 32 does not rotate for 2 seconds, the main controller controls The motor 32 is directly reversed. Finally, during the rotation of the wind deflector 31, the bump 33 is driven to touch the contact of the micro switch 34, and the main controller commands the motor 32 to rotate forward for 45° and then stop, reaching the position shown in Figure 4. Location. After starting the baking mode for 2 seconds, the main controller controls the motor 32 to perform a self-check (when the motor 32 moves to the maximum angle, because of the limited structure, when the motor 32 does not rotate for 2 seconds, the motor 32 directly reverses), After the protruding point of the wind deflector touches the contact point of the micro switch 34, the main controller orders the motor 32 to stop working, and reaches the position shown in Fig. 1 . Therefore, even if there is a sudden power failure of the microwave oven, the air guide structure will not work abnormally.
