Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a direct-cooling refrigerator that reduces frost buildup. Background Technology

[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. Inside the refrigerator is a compressor, an ice maker, a cabinet or box for freezing ice, and a storage box with a refrigeration unit. The capacity of a household refrigerator typically ranges from 20 to 500 liters.

[0003] A refrigerator is a device that uses the cooling effect of the refrigerant in the refrigeration circuit during compression, condensation, expansion and evaporation to maintain the interior of the refrigerator at a low temperature, thereby preserving food. The device is equipped with [missing information].

[0004] Direct-cooling refrigerators are essentially frost-producing refrigerators. They rely on an evaporator for cooling. The refrigerant flows within the evaporator, absorbing heat during evaporation. Since the evaporator is located behind the refrigerator's inner wall or inside the refrigerator, it absorbs heat from within, thus cooling the entire refrigerator. The evaporator in direct-cooling refrigerators typically uses a plate-tube or wire-tube design. The surface of the evaporator comes into direct contact with the warm, humid air inside the freezer compartment. Because warm air is less dense than cold air, frost forms on the inner wall of the evaporator tubes. This is especially problematic when the refrigerator is opened, as warm outside air enters the freezer compartment, causing moisture in the air to condense into frost. Therefore, minimizing the amount of outside air entering the freezer compartment when opening the refrigerator is a critical issue that needs to be addressed. Utility Model Content

[0005] In order to reduce the amount of outside air entering the refrigerator when it is opened, and to reduce the amount of moisture in the air that causes pre-cooling and frost formation, this application provides a direct-cooling refrigerator that reduces frost formation.

[0006] The direct-cooling refrigerator that reduces frost formation provided in this application adopts the following technical solution:

[0007] A direct-cooling refrigerator with reduced frost formation includes a cabinet body with a door hinged to one side. A storage cavity is located inside the cabinet body, and an empty cavity is formed on the side of the cabinet body away from the door. A connecting hole is formed near the top of the cabinet body to connect the empty cavity and the storage cavity. A spare cavity is formed on the top of the cabinet body and a side wall perpendicular to the door, and the spare cavity on the top and side wall is connected. Multiple air inlets are formed on the side wall of the cabinet body to connect the spare cavity and the storage cavity. A movable plate is slidably connected inside the cabinet body, and through holes corresponding to the air inlets are formed on the movable plate. A guide post is fixedly connected to the side of the movable plate near the door, extending out of the cabinet body near the door. A buffer spring is fixedly connected to the side of the movable plate away from the guide post, and the end of the buffer spring away from the movable plate is fixedly connected to the inner wall of the cabinet body. A conduit connecting the spare cavity and the empty cavity is fixedly connected to the side wall of the cabinet body.

[0008] By adopting the above technical solution, when the user closes the door, the guide column is pushed inward to slide, which in turn pushes the moving plate inward and squeezes the buffer spring. This causes the through hole on the moving plate to be misaligned with the air inlet on the inner wall of the refrigerator, thereby closing the storage cavity and the spare cavity. The cold air in the storage cavity is exchanged and cooled through the air guide channel and the connecting hole. When the door is opened, the pressure of the door on the guide column disappears, and the tension of the buffer spring pushes the moving plate outward to slide, connecting the through hole on the moving plate with the air inlet on the inner wall of the refrigerator. This facilitates the airflow in the spare cavity to enter the storage cavity, increasing the air pressure in the storage cavity. A large amount of cold air enters the storage cavity through the air inlet, making the air pressure in the storage cavity greater than the air pressure outside the refrigerator, thereby reducing the amount of air entering the storage cavity.

[0009] Optionally, two guide bars are fixedly connected to the inner wall of the box. The guide bars are located above and below the air inlet. The guide bars are folded inward on the opposite side to form a limiting groove, and the moving plate is slidably connected in the limiting groove.

[0010] By adopting the above technical solution, when the user pushes the guide column and the moving plate to slide horizontally, the moving plate slides in the limiting groove. The limiting strip plays a guiding and limiting role for the moving plate, making the moving plate more stable during the sliding process.

[0011] Optionally, the storage cavity is provided with a corrugated cover, and each cavity is provided with an air pump. The air pump is connected to an inflation pipe that communicates with the inside of the corrugated cover, and the air pump is connected to an exhaust pipe that communicates with the inside of the corrugated cover.

[0012] By adopting the above technical solution, when the user opens the door, the through hole on the moving plate and the air inlet on the inner wall of the box are connected, and the airflow in the spare chamber enters the storage chamber. The air pump inflates the corrugated cover, which supports the corrugated cover in the spare chamber. The corrugated cover compresses the cold air in the spare chamber, so that the air pressure in the spare chamber continuously delivers cold air to the storage chamber, further reducing the amount of air entering the storage chamber.

[0013] Optionally, a one-way valve is fixedly connected to the guide pipe.

[0014] By adopting the above technical solution, when the user uses it, the guide pipe is used to connect the spare chamber and the empty chamber, and the one-way valve only allows the cold air in the empty chamber to enter the spare chamber, which facilitates the cold air in the empty chamber to enter the spare chamber for storage.

[0015] Optionally, a guide block is fixedly connected to the bottom of the corrugated cover at the top of the box body. The guide block has an inclined surface one, which slopes downward from the box door side toward the cavity. The box body is horizontally slidably connected to a limiting block at the top of the corrugated cover. The limiting block has an inclined surface two that cooperates with the inclined surface one. The limiting block is fixedly connected to the corrugated cover. A top rod is fixedly connected to the side of the limiting block near the box door. The top rod extends out of the box body near the box door.

[0016] By adopting the above technical solution, when the user closes the cabinet door, the cabinet door presses against the connecting plate, and the connecting plate pushes the limiting block to press the corrugated cover into the cabinet, which facilitates the corrugated cover to contract. On the one hand, it facilitates the cold air inside the corrugated cover to quickly enter the cavity through the exhaust pipe, and on the other hand, it facilitates the cold air inside the cavity to enter the spare cavity through the guide pipe.

[0017] Optionally, a return spring is fixedly connected to the side of the limiting block away from the door, and a baffle is fixedly connected inside the box, with the end of the return spring away from the limiting block fixedly connected to the baffle.

[0018] By adopting the above technical solution, when the user opens the door, the tension of the reset spring quickly pops the limit block open, causing the bellows cover to expand quickly, which facilitates the compression of air in the spare chamber and also facilitates the exhaust pipe to exhaust into the bellows cover.

[0019] Optionally, a top block is fixedly connected to the corrugated cover of the box sidewall near the inner wall of the box. The top block has a three-sided inclined surface, which slopes downward from the side of the box door towards the cavity side. A storage block is slidably connected to the side of the corrugated cover away from the top block. The storage block has a four-sided inclined surface, which is used to cooperate with the three-sided inclined surface. A top material rod is fixedly connected to the side of the storage block near the box door. The top material rod extends out of the box body near the box door.

[0020] By adopting the above technical solution, when the user closes the box door, the box door presses the top rod, and the top rod pushes the storage block into the box to press the corrugated cover, which facilitates the shrinkage of the corrugated cover. On the one hand, it facilitates the rapid entry of the cold air in the corrugated cover into the cavity through the exhaust pipe, and on the other hand, it facilitates the entry of the cold air in the cavity into the spare cavity through the guide pipe.

[0021] Optionally, a compression spring is fixedly connected to the side of the storage block away from the box door, and a baffle plate is fixedly connected inside the box, with the end of the compression spring away from the storage block fixedly connected to the baffle plate.

[0022] By adopting the above technical solution, when the user opens the cabinet door, the tension of the compression spring quickly pops the storage block open, causing the corrugated cover to expand quickly, which facilitates the compression of air in the spare chamber and also facilitates the exhaust pipe to exhaust into the corrugated cover.

[0023] Optionally, a water vapor filter is provided at the location of the connecting hole of the housing. The water vapor filter is used to absorb moisture in the air that enters the cavity through the connecting hole.

[0024] By adopting the above technical solution, when the user uses the water vapor filter, it can absorb the moisture in the air that enters the cavity through the connecting hole, preventing moisture from entering the cavity and reducing frost formation on the evaporator tube.

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a direct-cooling refrigerator that reduces frost buildup, referring to... Figure 1 and Figure 2 The refrigerator includes a cabinet 1, with a door 11 hinged to one side of the cabinet 1. It is shown in the figure as a three-door refrigerator. A storage cavity 12 is provided inside the cabinet 1. A cavity 13 is provided on the side of the cabinet 1 away from the door 11. A freezing evaporation pipe 14 is provided in the cavity 13 near the freezer compartment. The freezing evaporation pipe 14 is used to cool the air circulating in the cavity 13.

[0034] A connecting hole 15 is provided near the top of the housing 1. The connecting hole 15 connects the cavity 13 and the storage cavity 12, allowing cold air from the cavity 13 to enter the storage cavity 12. A water vapor filter 16 is installed at the location of the connecting hole 15. The water vapor filter 16 absorbs moisture from the air entering the cavity 13 through the connecting hole 15, preventing moisture from entering the cavity 13 and reducing frost formation on the evaporator tube 14. Each storage cavity 12 has a venting channel 17 perpendicular to the side wall of the door 11. The venting channel 17 is connected to the cavity 13 and has an exhaust port 171, allowing cold air from the interlayer to enter the venting channel 17 and finally enter the storage cavity 12 through the exhaust port 171.

[0035] Reference Figure 3 and Figure 4When the refrigerator door 11 is opened, the temperature in the refrigerator compartment is very low. Repeated opening of the refrigerator allows outside air to enter, creating a temperature difference that causes water vapor in the air to pre-cool and easily frost up. To reduce the amount of outside air entering the refrigerator, a spare cavity 2 is provided on the top of the cabinet 1 and on the side wall perpendicular to the door 11. The spare cavity 2 on the top and side wall is connected. Multiple air inlets 21 are provided on the side wall of the cabinet 1, connecting the spare cavity 2 and the storage cavity 12. The air inlets 21 are horizontally distributed along the side wall of the refrigerator. Two guide strips 22 are fixedly connected to the inner wall of the cabinet 1, located above and below the air inlets 21. The guide strips 22 are horizontally positioned, and one side of each guide strip 22 folds inward to form a limiting groove 23. A movable plate 24 is slidably connected within the limiting groove 23. The movable plate 24 has through holes 241 that correspond one-to-one with the air inlet 21. A guide post 25 is fixedly connected to the side of the movable plate 24 near the door 11. The guide post 25 extends out of the box body 1 and is fixedly connected to a connecting plate 28. Two buffer springs 26 are fixedly connected to the side of the movable plate 24 away from the guide post 25. The buffer springs 26 are horizontally set. One end of the buffer spring 26 is fixedly connected to the movable plate 24, and the other end is fixedly connected to the inner wall of the box body 1. A guide pipe 27 is fixedly connected to the side wall of the box body 1. The guide pipe 27 is used to connect the spare chamber 2 and the cavity 13. A one-way valve 271 is fixedly connected to the guide pipe 27. The one-way valve 271 only allows the cold air in the cavity 13 to enter the spare chamber 2, so that the cold air in the cavity 13 can enter the spare chamber 2 for storage.

[0036] When the door 11 is closed, the guide post 25 is pushed to slide inward, and the moving plate 24 is pushed inward and squeezed by the buffer spring 26, so that the through hole 241 on the moving plate 24 and the air inlet 21 on the inner wall of the box 1 are misaligned, thereby closing the storage cavity 12 and the spare cavity 2. The cold air in the storage cavity 12 is exchanged and cooled through the air guide channel 17 and the connecting hole 15. After the door 11 is opened, the pressure of the door 11 on the connecting plate 28 and the guide post 25 is eliminated, and the tension of the buffer spring 26 pushes the moving plate 24 to slide outward, so that the through hole 241 on the moving plate 24 and the air inlet on the inner wall of the box 1 are connected, so that the airflow in the spare cavity 2 can enter the storage cavity 12, increasing the air pressure in the storage cavity 12. A large amount of cold air enters the storage cavity 12 through the air inlet, and the air pressure in the storage cavity 12 is greater than the air pressure outside the box 1, thereby reducing the amount of air entering the storage cavity 12.

[0037] To facilitate the continuous flow of air from the spare chamber 2 into the storage chamber 12 when the door 11 is opened, a corrugated cover 3 is installed inside the storage chamber 12. The two ends of the corrugated cover 3 are closed. Inflating the corrugated cover 3 will lift it up, and deflating it will cause it to contract. Air pumps 31 are installed on the inner wall of the cavity 13 at the positions of the spare chamber 2 on the side wall and the spare chamber 2 at the top. An inflation pipe 32 is connected to the air pump 31 and communicates with the inside of the corrugated cover 3. An exhaust pipe 33 is connected to the air pump 31 and communicates with the inside of the corrugated cover 3. After the door 11 is opened, the through hole 241 on the movable plate 24 connects with the air inlet on the inner wall of the box 1, and the airflow in the spare chamber 2 enters the storage chamber 12. The air pump 31 inflates the corrugated cover 3, which supports the corrugated cover 3 in the spare chamber 2. The corrugated cover 3 compresses the cold air in the spare chamber 2, so that the air pressure in the spare chamber 2 continuously delivers cold air to the storage chamber 12, further reducing the amount of air entering the storage chamber 12. When the door 11 is closed, the airflow in the corrugated cover 3 slowly enters the cavity 13 through the exhaust pipe 33, reducing the area of ​​the spare chamber 2 occupied by the corrugated cover 3, making it easier to store more cold air in the spare chamber 2 for use when the door 11 is opened.

[0038] Reference Figure 3 and Figure 5 A guide block 34 is fixedly connected to the bottom of the corrugated cover 3 at the top of the box body 1. The guide block 34 has an inclined surface 341, which slopes downward from the box door 11 towards the cavity 13. Two guide rails 35 are fixedly connected to the top of the corrugated cover 3 at the box body 1. A limit block 351 is horizontally slidably connected to the guide rails 35. The limit block 351 has an inclined surface 352 that cooperates with the inclined surface 341. The limit block 351 is fixedly connected to the corrugated cover 3. A top rod 355 is fixedly connected to the side of the limit block 351 near the box door 11. The top rod 355 extends out of the box body 1 and is fixedly connected to the connecting plate 28. A return spring 353 is fixedly connected to the side of the limit block 351 away from the box door 11. A baffle 354 is fixedly connected inside the housing 1, and the end of the return spring 353 away from the limiting block 351 is fixedly connected to the baffle 354. When the door 11 is closed, the door 11 presses the connecting plate 28, and the connecting plate 28 pushes the limiting block 351 to press the corrugated cover 3 into the housing 1, which facilitates the contraction of the corrugated cover 3. On the one hand, it facilitates the rapid entry of the cold air in the corrugated cover 3 into the cavity 13 through the exhaust pipe 33, and on the other hand, it facilitates the entry of the cold air in the cavity 13 into the spare cavity 2 through the guide pipe 27. When the door 11 is opened, the tension of the return spring 353 quickly pushes the limiting block 351 open, causing the corrugated cover 3 to expand rapidly, which facilitates the compression of the air in the spare cavity 2 and also facilitates the exhaust pipe to exhaust into the corrugated cover 3.

[0039] Reference Figure 3 and Figure 6A top block 36 is fixedly connected to the corrugated cover 3 on the side wall of the box 1 near the inner wall of the box 1. An inclined surface 361 is formed on the top block 36, which slopes downwards from the side of the box door 11 towards the side of the cavity 13. A storage block 371 is slidably connected to the side of the corrugated cover 3 away from the top block 36. Two limiting strips 37 are fixedly connected to the inner wall of the box 1 at the position corresponding to the storage block 371, forming a groove between the two limiting strips 37. The storage block 371 is slidably connected within the groove formed by the limiting strips 37. An inclined surface 372 is formed on the storage block 371, which is used to cooperate with the inclined surface 361. A top rod 373 is fixedly connected to the side of the limiting block 351 near the box door 11. The top rod 373 extends out of the box 1 and is fixedly connected to the connecting plate 28. A compression spring 374 is fixedly connected to the side away from the door 11, and a baffle plate 375 is fixedly connected inside the box body 1. The end of the compression spring 374 away from the storage block 371 is fixedly connected to the baffle plate 375. When the door 11 is closed, the door 11 presses the connecting plate 28, and the connecting plate 28 pushes the limiting block 351 to press the corrugated cover 3 into the box body 1, which facilitates the contraction of the corrugated cover 3. On the one hand, it facilitates the rapid entry of the cold air in the corrugated cover 3 into the cavity 13 through the exhaust pipe 33. On the other hand, it facilitates the entry of the cold air in the cavity 13 into the spare cavity 2 through the guide pipe 27. When the door 11 is opened, the tension of the compression spring 374 quickly pushes the storage block 371 open, causing the corrugated cover 3 to expand rapidly, which facilitates the compression of the air in the spare cavity 2 and also facilitates the exhaust pipe to exhaust into the corrugated cover 3.

[0040] The bottom of the corrugated cover 3 is equipped with a top block 36, a storage block 371 and a compression spring 374 with the same structure. The top material rod 373 connected to the storage block 371 extends out of the box body 1 and directly contacts the box door 11. This will not be described in detail here.

[0041] The implementation principle of a direct-cooling refrigerator that reduces frost formation according to an embodiment of this application is as follows: When the door 11 is opened, the pressure of the door 11 on the connecting plate 28 and the top material rod 373 disappears, and the pressure of the door 11 on the connecting plate 28 and the guide post 25 also disappears. The tension of the buffer spring 26 pushes the moving plate 24 to slide outward, so that the through hole 241 on the moving plate 24 connects with the air inlet hole on the inner wall of the cabinet 1, which facilitates the airflow in the spare compartment 2 to enter the storage compartment 12, thereby increasing the air pressure in the storage compartment 12. A large amount of cold air enters the storage compartment 12 through the air inlet hole, and the air pressure in the storage compartment 12 is high. The air pressure outside the refrigerator reduces the amount of air entering the storage cavity 12. At the same time, the tension of the compression spring 374 on the side wall quickly pops the storage block 371 open, causing the corrugated cover 3 to expand rapidly, which facilitates the compression of the air in the spare cavity 2. This allows the cold air in the spare cavity 2 to enter the storage cavity 12 through the through hole 241 and the air inlet, and also facilitates the exhaust pipe to exhaust into the corrugated cover 3. Meanwhile, the tension of the return spring 353 quickly pops the limiting block 351 open, causing the corrugated cover 3 to expand rapidly, which facilitates the compression of the air in the spare cavity 2, and also facilitates the exhaust pipe to exhaust into the corrugated cover 3.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
