技术领域technical field
本发明涉及冰箱储物领域，特别是涉及一种分路送风装置及冰箱。The invention relates to the field of refrigerator storage, in particular to a branch air supply device and a refrigerator.
背景技术Background technique
目前，风冷冰箱通过内置的蒸发器产生冷风，冷风通过风道循环流动至冰箱的各个储物间室实现制冷。对于风冷冰箱，食物的保鲜性能很大程度取决于储物间室内气流循环是否合理。如果冷风经风道随机流动，容易造成进入各储物间室内的风量过多或不足，使储物间室内的温度分布不均衡，冰箱的运行效率也会降低。因此，有必要对进入各储物间室内的冷风进行精确地流向分配和流量控制。同样地，为优化存储空间，单个储物间室一般会被搁物架或者抽屉等搁物装置分隔为多个细化的储物空间，根据存放物品的多少，每一个储物空间所需要的冷量也是不同的，因此，冷风不加控制地直接从储物间室的某处直接进入储物间室内，会造成部分储物空间过冷，部分储物空间冷量不足的问题。At present, the air-cooled refrigerator generates cold air through a built-in evaporator, and the cold air circulates through the air duct to each storage compartment of the refrigerator to achieve cooling. For air-cooled refrigerators, the freshness of food largely depends on whether the air circulation in the storage room is reasonable. If the cold air flows randomly through the air duct, it is easy to cause too much or insufficient air volume entering the storage rooms, making the temperature distribution in the storage rooms unbalanced, and the operating efficiency of the refrigerator will also be reduced. Therefore, it is necessary to accurately distribute and control the flow of cold air entering each storage compartment. Similarly, in order to optimize the storage space, a single storage room is generally divided into multiple detailed storage spaces by storage devices such as shelves or drawers. The cooling capacity is also different. Therefore, if the cold wind directly enters the storage room from somewhere in the storage room without control, it will cause the problem that some storage spaces are overcooled and some storage spaces have insufficient cooling capacity.

图1是根据本发明一个实施例的分路送风装置的示意性结构图。如图1所示，并参考图2至图11，本发明实施例提供了一种用于冰箱的分路送风装置400。该分路送风装置400可包括壳体410、多个挡板420、多个传动组件和驱动装置。Fig. 1 is a schematic structural diagram of a branch air supply device according to an embodiment of the present invention. As shown in FIG. 1 , and with reference to FIGS. 2 to 11 , an embodiment of the present invention provides a branch air supply device 400 for a refrigerator. The branch air supply device 400 may include a housing 410, a plurality of baffles 420, a plurality of transmission components and a driving device.
壳体410具有周壁部412，周壁部412上设置有多个送风口411，且多个送风口411沿壳体410的周向方向依次间隔设置。送风口411也可为具有一定长度的送风通道。进一步地，壳体410还可包括设置于周壁部412两端的结构。每个挡板420可转动地安装于一个送风口411处，以转动到不同的位置处来调整相应送风口411的出风面积，例如可打开或关闭相应送风口411，实现完全出风和零出风。则相应的每个挡板420可具有第一位置和第二位置，第一位置和第二位置之一为关闭相应送风口411，另一为打开相应送风口411。每个传动组件可安装于壳体410，配置成带动相应挡板420在第一位置和第二位置之间转动，以及使挡板420保持处于第一位置或第二位置。驱动装置可安装于壳体410，可具有驱动源450和传动机构，传动机构配置成将驱动源450输出的一个运动传递至多个转动组件。The housing 410 has a peripheral wall portion 412 , and a plurality of air outlets 411 are disposed on the peripheral wall portion 412 , and the plurality of air outlets 411 are sequentially arranged at intervals along the circumferential direction of the housing 410 . The air supply port 411 can also be an air supply channel with a certain length. Further, the casing 410 may further include structures disposed at both ends of the peripheral wall portion 412 . Each baffle plate 420 is rotatably installed at an air supply port 411, so as to adjust the air outlet area of the corresponding air supply port 411 by rotating to different positions, for example, the corresponding air supply port 411 can be opened or closed to realize complete air outlet and zero air outlet. Out of the wind. Then each corresponding baffle plate 420 may have a first position and a second position, one of the first position and the second position is to close the corresponding air supply port 411 , and the other is to open the corresponding air supply port 411 . Each transmission assembly can be mounted on the housing 410 and configured to drive the corresponding baffle 420 to rotate between the first position and the second position, and keep the baffle 420 in the first position or the second position. The driving device can be mounted on the casing 410 and can have a driving source 450 and a transmission mechanism configured to transmit a movement output by the driving source 450 to a plurality of rotating components.
进一步地，每个传动组件可具有具有转动件430、锥齿轮、离合机构和复位装置。转动件430的一侧为与锥齿轮配合的非连续锥齿轮结构。锥齿轮经由离合机构连接于相应挡板420，以在与转动件啮合时使相应挡板由第一位置转动到第二位置。离合机构配置成在相应挡板由第一位置转动地第二位置后，且在转动件与锥齿轮啮合力的作用下，使相应挡板静止时不阻止锥齿轮和转动件的转动，以使相应挡板420保持处于第二位置。复位装置安装于挡板，配置成在锥齿轮与转动件脱离啮合时，促使相应挡板回复到第一位置。传动机构可与多个转动件430配合，以使每个转动件430静止或转动。也就是说，驱动源450在输出旋转运动或直线运动等运动时，多个转动件430可在传动机构的带动下转动或保持静止。Further, each transmission assembly may have a rotating member 430, a bevel gear, a clutch mechanism and a reset device. One side of the rotating member 430 is a discontinuous bevel gear structure matched with bevel gears. The bevel gear is connected to the corresponding baffle plate 420 via the clutch mechanism, so that the corresponding baffle plate can rotate from the first position to the second position when engaging with the rotating member. The clutch mechanism is configured so that after the corresponding baffle is rotated from the first position to the second position, and under the action of the meshing force of the rotator and the bevel gear, the rotation of the bevel gear and the rotator is not prevented when the corresponding baffle is stationary, so that The corresponding baffle 420 remains in the second position. The reset device is mounted on the baffle and is configured to urge the corresponding baffle to return to the first position when the bevel gear is disengaged from the rotating member. The transmission mechanism can cooperate with a plurality of rotating parts 430, so that each rotating part 430 is stationary or rotating. That is to say, when the driving source 450 outputs rotational motion or linear motion, the plurality of rotating parts 430 can rotate or remain stationary driven by the transmission mechanism.
本发明实施例中的分路送风装置400的多个挡板420能够将冷风可控地分配至多个送风口411，实现多种出风状态，可以实现控制与每个送风口411连通的出风风道的开闭和/或对每个出风风道内的出风风量进行调节，进而来满足不同储物间室的冷量需求，或者一个储物间室的不同的位置处的冷量需求，或者一个储物间室内不同的储物空间的冷量需求。具体工作时，驱动源450通过传动机构带动多个转动件430转动，每个转动件430在转动时，通过锥齿轮、离合机构和复位装置，使相应的挡板420翻转，以打开或关闭或调整相应的送风口411。进一步地，由于传动组件可使相应挡板420翻转或保持不动，进而可使多个送风口411实现多种出风状态，例如一个送风口411关闭、另一个送风口411打开，两个送风口411同时关闭等出风状态。进一步地，本发明实施例中的的分路送风装置400的多个送风口411呈圆周式或四周式排布，可实现多个(如3个)送风口411周向出风，可便于分路送风装置400的整体结构设计，可使分路送风装置400的结构简单紧凑，布局合理；便于在冰箱中安装，便于冰箱内风道的合理布置。The plurality of baffles 420 of the split air supply device 400 in the embodiment of the present invention can controllably distribute the cold air to a plurality of air supply outlets 411, realize various air outlet states, and control the outlet connected to each air supply outlet 411. The opening and closing of the air duct and/or the adjustment of the air volume in each air outlet duct to meet the cooling demand of different storage compartments, or the cooling capacity at different positions of a storage compartment demand, or the cooling demand of different storage spaces in a storage room. When working specifically, the driving source 450 drives a plurality of rotating parts 430 to rotate through the transmission mechanism. When each rotating part 430 rotates, the corresponding baffle plate 420 is turned over through the bevel gear, the clutch mechanism and the reset device to open or close or Adjust the corresponding air outlet 411. Furthermore, since the transmission assembly can make the corresponding baffle plate 420 turn over or keep still, multiple air supply ports 411 can be realized in various air outlet states, for example, one air supply port 411 is closed, the other air supply port 411 is opened, and the two air supply ports 411 are opened. The tuyere 411 is closed simultaneously and waits for the air outlet state. Further, the plurality of air supply outlets 411 of the branch air supply device 400 in the embodiment of the present invention are arranged in a circular or four-sided manner, so that multiple (such as three) air supply outlets 411 can discharge air in the circumferential direction, which can facilitate The overall structural design of the branch air supply device 400 can make the structure of the branch air supply device 400 simple and compact, and the layout is reasonable; it is convenient to install in the refrigerator and to facilitate the reasonable arrangement of the air duct in the refrigerator.
在本发明的一些实施例中，复位装置为扭簧。离合机构可为摩擦式离合机构。例如，当挡板处于第一位置时，转动件开始转动，非连续锥齿轮结构开始与锥齿轮啮合，离合机构使得锥齿轮与挡板的转轴之间的摩擦力足以使锥齿轮带动挡板转动，直至挡板转动到第二位置。当挡板转动到第二位置后，需要调整多个送风口的出风状态时，而转动第二位置的挡板可能还要处于第二位置，此时非连续锥齿轮结构与锥齿轮之间的啮合力可足够大，可克服锥齿轮与挡板的转轴之间的摩擦力以不足以阻止转动件的转动，且可使挡板保持处于第二位置。在本发明的一些实施例中，离合机构可包括设置于挡板转轴端面的多个伸缩球头，以及设置于锥齿轮端面的多个凹槽。在本发明的又一些实施例中，离合机构包括设置于挡板的转轴上的多个弹性卡扣，以及设置于锥齿轮的转孔内的与弹性卡扣配合的且沿转孔的轴线方向延伸的多个卡槽。In some embodiments of the present invention, the reset device is a torsion spring. The clutch mechanism can be a friction clutch mechanism. For example, when the baffle is in the first position, the rotating part starts to rotate, the discontinuous bevel gear structure starts to mesh with the bevel gear, and the clutch mechanism makes the friction between the bevel gear and the rotating shaft of the baffle enough to make the bevel gear drive the baffle to rotate , until the bezel rotates to the second position. When the baffle is rotated to the second position, it is necessary to adjust the air outlet status of multiple air outlets, and the baffle rotated to the second position may also be in the second position. At this time, the gap between the discontinuous bevel gear structure and the bevel gear The meshing force can be large enough to overcome the frictional force between the bevel gear and the rotating shaft of the baffle to be insufficient to stop the rotation of the rotating member and keep the baffle in the second position. In some embodiments of the present invention, the clutch mechanism may include a plurality of telescopic ball heads arranged on the end surface of the rotating shaft of the baffle, and a plurality of grooves arranged on the end surface of the bevel gear.
