本发明涉及家用电器中冰箱的技术领域，尤其涉及一种风冷冰箱的风冷控制方法。The invention relates to the technical field of refrigerators in household appliances, in particular to an air-cooling control method for an air-cooled refrigerator.
背景技术Background technique
风冷冰箱制冷速度更快，并且解决了人工除霜的问题，因此市场占有量越来越大。对于常用的风冷冰箱来说，冷藏室所需要的冷量来自冷冻蒸发器的低温空气。低温空气从位于冷藏室后部的风道内流动，通过出风口进入冷藏室进行冷却。当冷藏室制冷时，冷冻风机运转，冷藏风门打开，温度较高的冷藏回风通过冷藏回风道进入蒸发器仓，经过蒸发器冷却后被输送到冷藏室中。而目前冷藏风门的打开都需要另外设置附带的电动调节装置来控制。通常是通过电机驱动门体旋转，当冷藏室的温度过高时，控制系统开启电机以驱动门体打开，形成风口，冷风通过该风口传输到冷藏室，从而对冷藏室进行降温，直到达到设定的温度为止。但该种电动控制的风门的风冷控制方法复杂，而且每次开启或关闭都需要电力驱动，从而大大提高了冰箱的能耗。Air-cooled refrigerators have faster cooling speed and solve the problem of manual defrosting, so their market share is increasing. For commonly used air-cooled refrigerators, the cooling capacity required by the refrigerator comes from the low-temperature air from the freezing evaporator. The low-temperature air flows from the air duct at the rear of the refrigerating room, and enters the refrigerating room through the air outlet for cooling. When the refrigerating room is cooling, the refrigerating fan runs, the refrigerating air door opens, and the high-temperature refrigerating return air enters the evaporator compartment through the refrigerating return air duct, and is transported to the refrigerating room after being cooled by the evaporator. At present, the opening of the refrigerating air door all needs to be controlled by an additional electric regulating device. Usually, the motor drives the door body to rotate. When the temperature of the refrigerator room is too high, the control system turns on the motor to drive the door body to open to form an air vent through which the cold air is transmitted to the refrigerator room to cool down the refrigerator room until it reaches the set temperature. up to the specified temperature. However, the air-cooling control method of the electrically controlled damper is complicated, and electric drive is needed every time it is opened or closed, thereby greatly increasing the energy consumption of the refrigerator.

具体实施方式detailed description
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
在本发明具体实施方式的描述中，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”和“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，通常以冰箱处于正常使用状态为参照，而并不是指示所指的位置或元件必须具有特定的方位。In describing specific embodiments of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" ", "inner" and "outer" are based on the orientation or positional relationship shown in the attached drawings, and usually refer to the normal use of the refrigerator, rather than indicating that the indicated position or element must have specific orientation.
如图1至图3所示，本发明一实施方式提供一种风冷冰箱，风冷冰箱包括冷藏室10、冷冻室12、蒸发器间室14和设于蒸发器间室14的蒸发器16。As shown in Figures 1 to 3, an embodiment of the present invention provides an air-cooled refrigerator, the air-cooled refrigerator includes a refrigerator compartment 10, a freezer compartment 12, an evaporator compartment 14 and an evaporator 16 located in the evaporator compartment 14 .
其中风冷冰箱还包括风机、将蒸发器16处的冷气传输到冷藏室10的进风风道20、将冷藏室10的热量传输回蒸发器间室14的回风风道22、活动设置于进风风道20中的阻隔挡板装置24，阻隔挡板装置24具有将进风风道20导通的开启位置和将进风风道20断开的关闭位置。当风机开启时，若风机产生的空气动力较低，将无法促使阻隔挡板装置24活动到开启位置，而当风机产生的空气动力较高以达到预定值时可足以促使阻隔挡板装置24活动到开启位置，此时进风风道20导通，蒸发器16与冷藏室10之间形成空气循环，以对冷藏室10进行制冷。而当风机关停时，风机不再产生空气动力，阻隔挡板装置24从开启位置活动到关闭位置，此时进风风道20断开，蒸发器16与冷藏室10之间不再进行空气循环。Wherein the air-cooled refrigerator also includes a blower fan, the cold air at the evaporator 16 is transmitted to the air intake duct 20 of the refrigerator compartment 10, the return air duct 22 that transmits the heat of the refrigerator compartment 10 back to the evaporator compartment 14, and is movable to be arranged on The blocking baffle device 24 in the air inlet duct 20 has an open position for conducting the air inlet duct 20 and a closed position for disconnecting the air inlet duct 20 . When the fan is turned on, if the aerodynamic force generated by the fan is low, it will not be able to impel the blocking baffle device 24 to move to the open position, but when the aerodynamic force generated by the fan is high enough to reach a predetermined value, it can be enough to promote the blocking baffle device 24 to move When it reaches the open position, the air inlet duct 20 is turned on at this time, and an air circulation is formed between the evaporator 16 and the refrigerating room 10 to cool the refrigerating room 10 . And when the fan is shut down, the fan no longer generates aerodynamic force, and the barrier baffle device 24 moves from the open position to the closed position. cycle.
本优选实施例中，不需要另外设置阻隔挡板装置24的打开控制机构，只需要风机产生的空气动力能克服阻隔挡板装置24的重量，就能使阻隔挡板装置24活动到开启位置。综上，该风冷冰箱结构非常简单、成本较低且比较节能。In this preferred embodiment, an additional opening control mechanism for the blocking baffle device 24 is not required, and only the aerodynamic force generated by the fan can overcome the weight of the blocking baffle device 24 to move the blocking baffle device 24 to the open position. In summary, the air-cooled refrigerator has a very simple structure, low cost and energy saving.
具体的，阻隔挡板装置24可转动地设置，风机为冷冻风机18，冷冻风机18可选择地与冷藏室10或冷冻室12连通，当冷冻风机18产生的空气动力达到预定值时可促使阻隔挡板装置24转动到开启位置，以使进风风道20导通，从而对冷藏室10进行制冷。当冷冻风机18关停时，阻隔挡板装置24从开启位置转动到关闭位置，以使进风风道20断开。当然，阻隔挡板装置24也可采用可滑移的设置。Specifically, the blocking baffle device 24 is rotatably arranged, and the fan is a freezing fan 18, which can be selectively communicated with the refrigerating room 10 or the freezing room 12, and when the aerodynamic force generated by the freezing fan 18 reaches a predetermined value, it can promote blocking The baffle device 24 is rotated to the open position, so that the air inlet duct 20 is conducted, so as to cool the refrigerator compartment 10 . When the refrigeration blower 18 is turned off, the blocking baffle device 24 turns from the open position to the closed position, so that the air inlet duct 20 is disconnected. Of course, the blocking baffle device 24 can also adopt a slidable arrangement.
冷冻风机18邻近蒸发器16设置，均设置于蒸发器间室14，其中蒸发器间室14设于冷冻室12的后侧。本优选实施例还提供了一种风冷冰箱的风冷控制方法，冷冻风机18设有预定转速，风冷控制方法包括如下步骤：将冷冻风机18的转速与预定转速比较；当冷冻风机18的转速小于预定转速时，冷冻风机18所产生的第一空气压力无法克服阻隔挡板装置24的重力所产生的扭矩，阻隔挡板装置24保持于关闭位置，冷冻风机18给冷冻室12输送冷量；当冷冻风机18的转速大于预定转速时，冷冻风机18所产生的第二空气压力足以克服阻隔挡板装置24的重力所产生的扭矩，阻隔挡板装置24从关闭位置转动到开启位置，冷冻风机18将冷气输送到冷藏室10。The refrigeration fan 18 is disposed adjacent to the evaporator 16 and is disposed in the evaporator compartment 14 , wherein the evaporator compartment 14 is disposed at the rear side of the freezing compartment 12 . This preferred embodiment also provides an air-cooling control method for an air-cooled refrigerator. The refrigerating fan 18 is provided with a predetermined rotating speed. The air-cooling control method includes the following steps: comparing the rotating speed of the refrigerating fan 18 with the predetermined rotating speed; When the rotational speed is less than the predetermined rotational speed, the first air pressure produced by the freezing fan 18 cannot overcome the torque generated by the gravity of the blocking baffle device 24, and the blocking baffle device 24 remains in the closed position, and the freezing fan 18 delivers cooling capacity to the freezing chamber 12. ; when the rotating speed of freezing fan 18 was greater than the predetermined rotating speed, the second air pressure produced by freezing fan 18 was sufficient to overcome the torque generated by the gravity of blocking baffle device 24, and blocking baffle device 24 rotated from closed position to open position, freezing The fan 18 delivers cold air to the refrigerator compartment 10 .
也就是说，当冷藏室10不需要制冷、而只有冷冻室12需要制冷时，冷冻风机18以低转速运行，此时冷冻风机18运行所产生的空气压力较低，无法克服阻隔挡板装置24的重力作用下的扭矩，阻隔挡板装置24保持于关闭位置，冷冻风机18给冷冻室12输送冷量。而当冷藏室10需要制冷时，则提高冷冻风机18的转速，当冷冻风机18的转速大于预定转速时，冷冻风机18运行所产生的空气压力较高，直到高于阻隔挡板装置24的重力作用下的扭矩，从而推动阻隔挡板装置24向上转动，在阻隔挡板装置24持续向上的转动过程中，因重力产生的扭矩会不断降低，因此阻隔挡板装置24能转动到最高位置，冷冻风机18将冷气送入冷藏室10。That is to say, when the refrigerating chamber 10 does not need to be refrigerated and only the freezing chamber 12 needs to be refrigerated, the refrigerating fan 18 operates at a low speed. Torque under the action of gravity, the blocking baffle device 24 remains in the closed position, and the freezing fan 18 delivers cooling capacity to the freezing chamber 12 . And when refrigerating chamber 10 needs cooling, then increase the rotating speed of freezing fan 18, when the rotating speed of freezing fan 18 is greater than predetermined rotating speed, the air pressure that freezing fan 18 operation produces is higher, until higher than the gravity of blocking baffle plate device 24 Torque under the action, thereby pushing the blocking baffle device 24 to rotate upwards, during the continuous upward rotation of the blocking baffle device 24, the torque generated by gravity will continue to decrease, so the blocking baffle device 24 can rotate to the highest position, freezing The fan 18 sends cold air into the refrigerator compartment 10 .
另外，冷藏室10设有需要达到的预定温度，风冷控制方法还包括如下步骤：检测冷藏室10的温度，当冷藏室10的温度达到预定温度时，关停冷冻风机18，此时冷冻风机18不再产生空气压力，阻隔挡板装置24在其重力作用下从开启位置转动到关闭位置。In addition, the refrigerating room 10 is provided with a preset temperature that needs to be reached, and the air-cooling control method also includes the following steps: detecting the temperature of the refrigerating room 10, and when the temperature of the refrigerating room 10 reaches the predetermined temperature, shutting down the freezing fan 18, and the freezing fan 18 is now 18 no longer generates air pressure, and the barrier flap assembly 24 rotates from the open position to the closed position under its gravity.
本优选实施例，冷冻风机18的转速可调，通过控制冷冻风机18的转速来控制阻隔挡板装置24的开启和关闭，从而控制冷藏室10的进风风道20的导通和断开，以实现将冷冻风机18的冷风相应地分别送入冷藏室10或冷冻室12。具体的，当进风风道20导通时，冷冻风机18的冷风送入冷藏室10，对冷藏室10进行制冷；当进风风道20断开时，冷冻风机18的冷风进入冷冻室12，对冷冻室12进行制冷。因此，该风冷控制方法非常简单，只需要控制冷冻风机18的转速，从而对应产生不同的空气压力来实现阻隔挡板装置24的开启和关闭。In this preferred embodiment, the rotating speed of the freezing fan 18 is adjustable, and the opening and closing of the barrier baffle device 24 is controlled by controlling the rotating speed of the freezing fan 18, thereby controlling the conduction and disconnection of the air inlet duct 20 of the refrigerating room 10, To realize that the cold wind of the freezing fan 18 is sent into the refrigerator compartment 10 or the freezer compartment 12 respectively. Specifically, when the air inlet duct 20 is turned on, the cold wind of the refrigeration fan 18 is sent into the refrigerator compartment 10, and the refrigerator compartment 10 is refrigerated; , the freezer compartment 12 is refrigerated. Therefore, the air-cooling control method is very simple, and only needs to control the rotation speed of the refrigeration fan 18 to generate different air pressures correspondingly to realize the opening and closing of the blocking baffle device 24 .
另外，根据不同冰箱的进风风道20设置的不同，可设置不同的预定转速，当高于预定转速时，只要对应产生的空气压力能打开阻隔挡板装置24即可。In addition, according to the different configurations of the air inlet ducts 20 of different refrigerators, different predetermined rotational speeds can be set. When the rotational speed is higher than the predetermined rotational speed, as long as the corresponding generated air pressure can open the blocking baffle device 24 .
本发明提供的另一实施例中，阻隔挡板装置24也采用可转动地设置，而风机包括冷冻风机18和挡板控制风机（未图示），本实施例中，单独设置一挡板控制风机，挡板控制风机用于控制阻隔挡板装置24的开启和关闭，冷冻风机18用于给冷藏室10或冷冻室12提供冷量。具体的，当挡板控制风机产生的空气动力达到预定值时可促使阻隔挡板装置24转动到开启位置，以使进风风道20导通，此时冷冻风机18与冷藏室10连通，当挡板控制风机关停时，阻隔挡板装置24从开启位置转动到关闭位置，以使进风风道20断开，此时冷冻风机18不再给冷藏室10输送冷风。In another embodiment provided by the present invention, the barrier baffle device 24 is also rotatably arranged, and the fan includes a refrigeration fan 18 and a baffle control fan (not shown). In this embodiment, a baffle control fan is separately provided. The fan, the baffle control fan is used to control the opening and closing of the blocking baffle device 24 , and the refrigerating fan 18 is used to provide cooling capacity for the refrigerating chamber 10 or the freezing chamber 12 . Specifically, when the aerodynamic force generated by the baffle control fan reaches a predetermined value, the blocking baffle device 24 can be urged to rotate to the open position, so that the air inlet duct 20 is conducted. When the baffle control fan is turned off, the blocking baffle device 24 is rotated from the open position to the closed position, so that the air inlet duct 20 is disconnected, and the refrigerating fan 18 no longer delivers cold air to the refrigerating chamber 10.
其中，挡板控制风机可设置成产生空气吸力，实现阻隔挡板装置24的打开，此时挡板控制风机设置于阻隔挡板装置24的上方，当挡板控制风机打开时，挡板控制风机产生的向上方向的空气吸力克服阻隔挡板装置24的重力，以将阻隔挡板装置24开启。当挡板控制风机关停时，挡板控制风机不再产生空气吸力，此时阻隔挡板装置24在其重力作用下转动到关闭位置。Wherein, the baffle control fan can be set to generate air suction to realize the opening of the barrier baffle device 24. At this time, the baffle control fan is arranged above the barrier baffle device 24. When the baffle control fan is opened, the baffle control fan The generated upward air suction overcomes the gravity of the blocking baffle device 24 to open the blocking baffle device 24 . When the baffle control fan is shut down, the baffle control fan no longer produces air suction, and now the barrier baffle device 24 rotates to the closed position under its gravity.
当然，挡板控制风机也可设置成产生空气压力，实现阻隔挡板装置24的打开，此时挡板控制风机设置于阻隔挡板装置24的下方，当挡板控制风机打开时，挡板控制风机产生向上方向的空气压力克服阻隔挡板装置24的重力，以将阻隔挡板装置24开启。而当挡板控制风机关停时，挡板控制风机不再产生空气压力，此时阻隔挡板装置24在其重力作用下转动到关闭位置。Of course, the baffle control fan can also be set to generate air pressure to realize the opening of the barrier baffle device 24. At this time, the baffle control fan is arranged under the barrier baffle device 24. When the baffle control fan is opened, the baffle control The blower generates upward air pressure to overcome the gravity of the blocking baffle device 24 to open the blocking baffle device 24 . And when the baffle control fan was shut down, the baffle control fan no longer produced air pressure, and now the barrier baffle device 24 rotated to the closed position under its gravity.
冷藏室10具有顶部26、与顶部26相对的底部28、连接顶部26和底部28的后部30、左侧部32和右侧部34，以构成具有开口部的收容腔，收容腔用于存放食物、饮料等。冷藏室10的后部30设有进风口36和出风口38，进风口36设置为复数个，蒸发器16处的冷气通过冷冻风机18吹入到进风风道20，进风风道20的冷气再通过进风口36输入到冷藏室10内，冷藏室10内的热量从出风口38进入到回风风道22，途径回风风道22后进入到蒸发器间室14，从而形成空气循环，对冷藏室10进行制冷。The refrigerator compartment 10 has a top 26, a bottom 28 opposite to the top 26, a rear portion 30 connecting the top 26 and the bottom 28, a left side 32 and a right side 34 to form a storage chamber with an opening, and the storage chamber is used to store food, drink etc. The rear portion 30 of the refrigerator compartment 10 is provided with an air inlet 36 and an air outlet 38, and the air inlet 36 is arranged as a plurality, and the cold air at the evaporator 16 is blown into the air inlet duct 20 by the freezing fan 18, and the air inlet duct 20 The cold air is then input into the refrigerator compartment 10 through the air inlet 36, and the heat in the refrigerator compartment 10 enters the return air duct 22 from the air outlet 38, passes through the return air duct 22, and then enters the evaporator compartment 14, thereby forming an air circulation , the refrigerator compartment 10 is refrigerated.
进一步参照图4和图5，进风风道20包括第一侧壁40和与第一侧壁40相隔一定间距且相对设置的第二侧壁42，阻隔挡板装置24包括通过第一枢轴44转动设于第一侧壁40的第一挡板46和通过第二枢轴48转动设于第二侧壁42的第二挡板50。从而降低了第一挡板46和第二挡板50的转动扭矩，使得风机产生较低的空气动力的情况下，就可开启第一挡板46和第二挡板50。Referring further to Fig. 4 and Fig. 5, the air inlet duct 20 includes a first side wall 40 and a second side wall 42 opposite to the first side wall 40 at a certain distance, and the blocking baffle device 24 includes a first pivot shaft 44 to rotate the first baffle 46 on the first side wall 40 and to rotate the second baffle 50 on the second side wall 42 through the second pivot 48 . Therefore, the rotational torque of the first baffle 46 and the second baffle 50 is reduced, so that the first baffle 46 and the second baffle 50 can be opened under the condition that the fan generates low aerodynamic force.
优选的，第一挡板46和第二挡板50均采用轻质材料制成。如塑料或轻质金属件。第一挡板46和第二挡板50可设置成薄片状，可以是刚性薄片，如金属薄片或刚性金属薄片。当然，也可以是柔性的膜片。Preferably, both the first baffle 46 and the second baffle 50 are made of lightweight materials. Such as plastic or lightweight metal parts. The first baffle plate 46 and the second baffle plate 50 can be arranged in a sheet shape, which can be a rigid sheet, such as a metal sheet or a rigid metal sheet. Of course, a flexible membrane is also possible.
进一步的，第一枢轴44与第二枢轴48相平行。第一枢轴44较第二枢轴48更远离顶部26，也就是说，第二枢轴48在第一枢轴44的上方。其中，第一挡板46具有第一最大开启位置（参见图3和图5）、第一关闭位置（参见图2和图4）和位于第一最大开启位置和第一关闭位置之间的第一中间开启位置，第二挡板50具有第二最大开启位置（参见图3和图5）、第二关闭位置（参见图2和图4）和位于第二最大开启位置和第二关闭位置之间的第二中间开启位置，第一挡板46定义了一平面，当第一挡板46处于第一关闭位置且第二挡板50处于第二关闭位置时，第一挡板46在平面上的投影与第二挡板50在平面上的投影部分重叠，且第一挡板46的上表面与第二挡板50的下表面相贴合。当第一挡板46处于第一关闭位置且第二挡板50处于第二关闭位置时，第二挡板50位于第一挡板46的上方，且第二挡板50与第一挡板46相平行。这样，由于第一挡板46和第二挡板50在关闭位置有一定的搭接，从而进一步保证了较好的密封效果。进一步的，第一挡板46和第二挡板50的搭接尺寸d不小于2mm。Further, the first pivot 44 is parallel to the second pivot 48 . The first pivot 44 is farther from the top 26 than the second pivot 48 , that is, the second pivot 48 is above the first pivot 44 . Wherein, the first baffle plate 46 has a first maximum opening position (refer to FIG. 3 and FIG. 5 ), a first closing position (refer to FIG. 2 and FIG. 4 ) and a second maximum opening position between the first maximum opening position and the first closing position. An intermediate open position, the second baffle 50 has a second maximum open position (see Figure 3 and Figure 5 ), a second closed position (see Figure 2 and Figure 4 ) and is located between the second maximum open position and the second closed position The second intermediate open position between, the first baffle 46 defines a plane, when the first baffle 46 is in the first closed position and the second baffle 50 is in the second closed position, the first baffle 46 is on the plane The projection of is partially overlapped with the projection of the second baffle 50 on the plane, and the upper surface of the first baffle 46 is attached to the lower surface of the second baffle 50 . When the first baffle 46 is in the first closed position and the second baffle 50 is in the second closed position, the second baffle 50 is located above the first baffle 46 , and the second baffle 50 and the first baffle 46 parallel. In this way, since the first baffle plate 46 and the second baffle plate 50 overlap to a certain extent in the closed position, a better sealing effect is further ensured. Further, the overlapping dimension d of the first baffle 46 and the second baffle 50 is not less than 2mm.
另外，第一关闭位置时，第一挡板46处于水平状态；第二关闭位置时，第二挡板50也处于水平状态。In addition, in the first closed position, the first baffle 46 is in a horizontal state; in the second closed position, the second baffle 50 is also in a horizontal state.
第一挡板46从第一关闭位置转动角度A达到第一最大开启位置，第二挡板50从第二关闭位置转动角度B达到第二最大开启位置，角度A小于角度B。当风机产生的空气压力足以打开第一挡板46和第二挡板50时，第二挡板50先绕第二枢轴48转动，这样第二挡板50不再阻挡第一挡板46，第一挡板46接着绕第一枢轴44转动。由于角度A小于角度B，当风机关停时，第一挡板46先于第二挡板50下落，从而保证了关闭时第二挡板50搭接于第一挡板46上方。The first flap 46 rotates an angle A from the first closed position to reach a first maximum open position, and the second flap 50 rotates an angle B from a second closed position to a second maximum open position, the angle A being smaller than the angle B. When the air pressure generated by the fan is sufficient to open the first baffle 46 and the second baffle 50, the second baffle 50 rotates around the second pivot 48 first, so that the second baffle 50 no longer blocks the first baffle 46, The first flap 46 then pivots about the first pivot 44 . Since the angle A is smaller than the angle B, when the fan is shut down, the first baffle 46 falls before the second baffle 50 , thereby ensuring that the second baffle 50 overlaps the first baffle 46 when it is closed.
进一步的，角度A的范围为30°≤A≤87°，角度A可以设置为30°、45°、60°、80°和87°等。Further, the range of the angle A is 30°≤A≤87°, and the angle A can be set to 30°, 45°, 60°, 80°, 87° and so on.
角度B的范围为30°≤B≤87°，同样，角度B可以设置为30°、45°、60°、80°和87°等。角度A和角度B的角度设置成不小于30°，保证了有较高的送风口面积，从而提高冷藏的制冷速度。具体的，角度B设置为87°时，角度A设置为80°。The range of the angle B is 30°≤B≤87°, similarly, the angle B can be set to 30°, 45°, 60°, 80°, 87° and so on. The angle of angle A and angle B is set to be not less than 30°, which ensures a relatively high air supply outlet area, thereby increasing the cooling speed of the refrigerator. Specifically, when the angle B is set to 87°, the angle A is set to 80°.
角度A和角度B的角度设置成不大于87°，这样使得第一挡板46在运动到第一最大开启位置和第二挡板50在运动到第二最大开启位置时，第一挡板46和第二挡板50的扭矩较低，从而冷冻风机18承受的动压力不会过高，进一步提高了冷冻风机18的送风效率。The angle of angle A and angle B is set to be no more than 87 °, so that when the first baffle plate 46 moves to the first maximum opening position and the second baffle plate 50 moves to the second maximum opening position, the first baffle plate 46 The torque of the second baffle plate 50 and the second baffle plate 50 are low, so that the dynamic pressure on the refrigeration fan 18 will not be too high, and the air supply efficiency of the refrigeration fan 18 is further improved.
本优选实施例中，第一侧壁40上设有容纳第一枢轴44的第一容置槽52，当第一挡板46处于第一最大开启位置时，第一挡板46至少部分容置于第一容置槽52。这样，进一步增大了送风口面积，更进一步提高冷藏的制冷速度。In this preferred embodiment, the first side wall 40 is provided with a first accommodating groove 52 for accommodating the first pivot 44. When the first baffle 46 is in the first maximum open position, the first baffle 46 is at least partially accommodated. Placed in the first accommodating groove 52. In this way, the area of the air supply port is further increased, and the cooling speed of the refrigerator is further improved.
进一步的，第二侧壁42上设有容纳第二枢轴48的第二容置槽54，当第二挡板50处于第二最大开启位置时，第二挡板50至少部分容置于第二容置槽54。Further, the second side wall 42 is provided with a second accommodating groove 54 for accommodating the second pivot 48. When the second baffle 50 is in the second maximum opening position, the second baffle 50 is at least partially accommodated in the first Two accommodating grooves 54 .
具体的，为使得送风口面积更大，当第一挡板46处于第一最大开启位置时，第一挡板46完全容置于第一容置槽52，当第二挡板50处于第二最大开启位置时，第二挡板50完全容置于第二容置槽54。Specifically, in order to make the area of the air supply port larger, when the first baffle 46 is at the first maximum opening position, the first baffle 46 is completely accommodated in the first accommodating groove 52, and when the second baffle 50 is at the second When the maximum opening position is reached, the second baffle 50 is completely accommodated in the second accommodating groove 54 .
另外，第一容置槽52具有将第一挡板46保持于第一关闭位置的第一止挡边56。第二容置槽54具有将第二挡板50保持于第二关闭位置的第二止挡边58。In addition, the first accommodating groove 52 has a first stop edge 56 for maintaining the first blocking plate 46 at the first closed position. The second accommodating groove 54 has a second stop edge 58 for maintaining the second blocking plate 50 at the second closed position.
