[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product that keeps food or other items at a constant low temperature. The air duct cover of a refrigerator is an important component of the refrigerator's air duct. Its main purpose is to introduce cold air from the evaporator into the air duct and blow it from the air outlet of the air duct to various parts of the refrigerator's internal cavity, thereby reducing the temperature of the refrigerator's internal cavity.

An air inlet pipe is mounted on the first fixing plate, and an air outlet pipe is mounted on the second fixing plate. The anti-frost device includes an anti-frost layer, a heating layer, a heat-conducting layer, and an insulation layer. A heat-conducting layer is mounted outside the anti-frost layer, a heating layer is mounted outside the heat-conducting layer, and an insulation layer is mounted outside the heating layer. This device can prevent frost from forming in the refrigerator air duct, making it convenient for people to remove frost from the refrigerator air duct, saving time and effort, preventing refrigerator damage, and increasing the refrigerator's lifespan.

[0004] While current refrigerator air ducts facilitate the passage of cold air, their air intake volume is relatively fixed, making it difficult to adjust the intake volume according to actual needs, thus narrowing the applicable range. In addition, to ensure the quality of intake air, filter plates are usually used to filter the air, but the filter plates are cumbersome to disassemble, resulting in reduced maintenance efficiency and thus reduced practicality.

The adjustment component includes a drive shaft 21 connected to both sides inside the air duct body 11, a motor 22 fixedly connected to one end of one of the drive shafts 21, a main gear 23 fixedly connected to the outside of the drive shaft 21, and an air adjusting plate 24 fixedly connected to the outside of the drive shaft 21. The drive shaft 21 is rotatably connected to the air duct body 11, the two main gears 23 mesh, the two air adjusting plates 24 are arranged vertically, and the motor 22 is fixedly connected to the upper drive shaft 21. When the motor 22 is started, it can control the drive shaft 21 and the main gear 23 to rotate, thereby driving the other main gear 23 and the drive shaft 21 to rotate. The rotation can drive the two air regulating plates 24 to rotate, thereby controlling the air intake of the air duct body 11 according to actual needs. A protective cover 41 is fixedly connected to one side of the air duct body 11. Multiple heat dissipation vents 42 are evenly arranged on one side of the protective cover 41. The motor 22 is fixedly connected to the inner wall of the protective cover 41.

[0025] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5The impurity removal components include an air inlet 31 on the front of the mounting plate 1, a filter plate 32 inside the air inlet 31, mounting cavities 33 on both sides of the mounting plate 1, a drive plate 34 inside the mounting cavity 33, a locking rod 35 fixedly connected to one side of the drive plate 34, locking grooves 36 on both sides of the filter plate 32, a screw 37 connected to the inner wall of the mounting cavity 33, a driven bevel gear 38 fixedly connected to the outer side of the screw 37, a driving bevel gear 39 connected to the driven bevel gear 38, and a fixed component to the driving bevel gear 39. The rotating shaft 40 is rotatably connected to the mounting plate 1. The drive plate 34 is screwed to the screw 37, which is rotatably connected to the inner wall of the mounting cavity 33. The locking rod 35 is inserted into the locking slot 36. The rotating shaft 40 can drive the active bevel gear 39 to rotate, which in turn drives the driven bevel gear 38 to rotate, thereby controlling the rotation of the screw 37. The screw 37 can control the movement of the drive plate 34, which in turn causes the locking rod 35 to move. The locking rod 35 can engage or disengage from the locking slot 36, thus enabling the filter to be adjusted. Fixing or disassembling plate 32 can improve the efficiency of filter plate 32 installation and disassembly, and simplify the disassembly and assembly steps. A guide groove 51 is provided on the inner wall of the installation cavity 33. A guide block 52 is slidably connected in the guide groove 51. The guide block 52 is fixedly connected to the drive plate 34. The movement of the drive plate 34 can drive the guide block 52 to move.

Limiting holes 72 are opened on the baffles 71. Limiting rods 73 are fixedly connected to both sides of the filter plate 32. The limiting rods 73 are inserted into the limiting holes 72, which can limit the filter plate 32 and ensure that the locking rod 35 can be aligned with the locking groove 36.

[0026] Working principle: During operation, the filter plate 32 is inserted into the air inlet 31, and the limiting rod 73 is inserted into the limiting port 72. Then, the knobs 62 on both sides can be rotated. Rotating the knobs 62 drives the rotating shaft 40 to rotate, which in turn drives the driving bevel gear 39 to rotate. The driving bevel gear 39 then drives the driven bevel gear 38 to rotate, which in turn drives the screw 37 to rotate. The screw 37 then moves the drive plate 34, which in turn moves the locking rod 35. The locking rod 35 then engages with the slot 36, thus fixing the filter plate 32. The filter plate 32 can then... The air is filtered to remove impurities, and the filtered air can enter the main body of the air duct 11. When the air intake needs to be adjusted, the motor 22 starts, which drives the drive shaft 21 to rotate. The drive shaft 21 drives the main gear 23 to rotate, which in turn drives another main gear 23 to rotate, which in turn drives another drive shaft 21 to rotate. The rotation of the two drive shafts 21 drives the two air regulating plates 24 to rotate, thereby controlling the air intake in the main body of the air duct 11.
