The refrigerator may also be a refrigerated display cabinet, a refrigerated wine cabinet, or a refrigerator. The refrigerator includes a housing 100, a door 200 rotatably covered on the housing 100, and a refrigeration component disposed in the housing 100. The refrigeration compartment is disposed in the housing 100, and the refrigeration component is used to generate cold energy for refrigeration of the refrigerator.

[0044] A refrigeration compartment with an opening on the front side is formed in the box body 100, and food is placed in the refrigeration compartment for low temperature storage. Specifically, an inner liner 110 is provided in the box body, and a refrigeration compartment with an opening on the front side is formed in the inner liner 110, and items are placed in the refrigeration compartment for low temperature storage. The box door 200 can be opened and closed on the front side of the box body 100 to open or close the refrigeration compartment in the box body 100, and items can be taken in and out of the refrigeration compartment. In this embodiment, the box door 200 can be rotatably covered on the front side of the box body 100 to open and close the refrigeration compartment.

[0045] A press chamber 120 is also provided in the refrigeration room, and the press chamber 120 is located below the inner tank 110. The press chamber 120 is located below the refrigeration room.

[0046] An air duct assembly is provided in the box 100. The refrigeration assembly transfers cold energy to the air in the air duct assembly, and provides cold air to the refrigeration compartment, so that the refrigeration compartment can obtain cold air in the air duct assembly. The air duct assembly can selectively penetrate the refrigeration compartment to introduce the air in the air duct assembly into the refrigeration compartment, so as to cool the refrigeration compartment.

[0047] In some embodiments, the refrigeration compartment includes a refrigerator compartment and a freezer compartment, and the air duct assembly can transport cold air to the refrigerator compartment and the freezer compartment respectively, so that the air in the air duct assembly can transfer cold air to the refrigerator compartment and the freezer compartment respectively to maintain a refrigerated environment in the refrigerator compartment and the freezer compartment.

[0048] A foam layer is provided between the inner liner 110 and the box body 100 . The foam layer is filled with foam material. The foam material surrounds the upper and lower, left and right and rear side walls of the refrigeration compartment, thereby insulating the refrigeration compartment and maintaining the temperature of the refrigeration compartment.

[0049] In some embodiments, the cabinet door 200 includes a freezer door for covering the freezer compartment, and a refrigerator door for covering the refrigerator compartment. The refrigerator door can be opened and closed to cover the front side of the refrigerator compartment and the temperature-changing chamber to open and close the refrigerator compartment and the temperature-changing chamber.

The freezer door and the refrigerator door are spaced apart in the left-right direction.

[0050] The refrigeration component is used to release the heat in the refrigerator to the outside environment, and to provide coldness to the refrigeration room to maintain the low temperature environment in the refrigeration room. The refrigeration component includes components such as a compressor, a condenser, an evaporator, and a capillary. The compressor, the condenser, the capillary, and the evaporator are connected in sequence, and the outlet of the evaporator is connected to the inlet of the compressor, thereby forming a channel for the circulation of the refrigerant in the compressor, the condenser, the capillary, and the evaporator. The compressor, the condenser, the capillary, and the evaporator are connected in sequence through pipelines.

[0051] In this embodiment, the compressor and the condenser are arranged in the compressor chamber 120, and a condenser pipe is arranged at the outlet of the condenser to transport the medium in the condenser to the downstream.

[0052] The air duct assembly and the refrigeration room are connected so that air circulates between the air duct assembly and the refrigeration room, thereby transferring the cold in the air duct assembly to the refrigeration room and transferring the heat in the refrigeration room to the air duct assembly. The low-temperature and low-pressure liquid refrigerant in the evaporator is converted into a low-temperature and low-pressure gaseous refrigerant after heat exchange with the air duct assembly. The low-temperature and low-pressure gaseous refrigerant in the evaporator is transferred to the compressor and compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor.

[0053] The high-temperature and high-pressure gaseous refrigerant in the compressor is transported to the condenser, where it releases heat to the outside environment, thereby converting the high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure liquid refrigerant. The low-temperature and high-pressure liquid refrigerant is converted into a low-temperature and low-pressure liquid refrigerant through the throttling and decompression effect of the capillaries. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator and the air in the air duct assembly for heat exchange.

[0054] The specific structure and connection relationship of the refrigeration assembly refer to the refrigeration assembly in the related art, and will not be repeated here. The specific structure and position relationship of the air duct assembly refer to the structure and position relationship of the air duct assembly in the related art, and will not be repeated here.

[0055] An evaporating dish 130 is provided in the compressor chamber 120 for receiving condensed water or defrosting water in the refrigeration room. In this embodiment, the condenser of the condenser extends into the evaporating dish 130 to cool the condenser tube through the water in the evaporator. The condenser tube in the evaporating dish 130 will cause the liquid water in the evaporating dish 130 to be vaporized into gaseous evaporation gas, and the evaporation gas will flow upward.

[0056] In this embodiment, the compressor chamber 120 can also be fixed above the compressor. When the hot air around the compressor flows upward, the liquid water in the evaporating dish 130 can also be used to cool the hot air for heat dissipation around the compressor.

[0057] A drain pipe 300 is also fixed in the housing 100, and the upper end of the drain pipe 300 is connected to the bottom of the refrigeration compartment; the lower end of the drain pipe 300 is located above the evaporation dish 130, so as to be used for the water in the drain pipe 300 to be introduced into the evaporation dish 130. The upper end of the drain pipe 300 is sealed and connected to the bottom of the refrigeration compartment. In one embodiment, the upper end of the drain pipe 300 is sealed and connected to the bottom of the refrigeration compartment. In some embodiments, the upper end of the drain pipe 300 is sealed and connected to the bottom of the freezer compartment.

[0058] Figure 4 It is a schematic diagram of the connection of the sealing structure of the utility model on the drainage pipe. Figure 5 yes Figure 4 Exploded schematic diagram of the structure shown. Figure 6 yes Figure 4 A cross-sectional view of the structure shown.

[0059] See also Figures 3 to 6 The drain pipe 300 is fixed with a sealing structure 400, which is used to form a liquid seal at the bottom of the drain pipe 300 to prevent the air in the external environment from exchanging with the gas in the refrigeration room through the drain pipe 300. The water discharged from the drain pipe 300 first enters the sealing structure 400, and forms a liquid seal structure in the sealing structure 400 to prevent heat exchange between the refrigeration room and the external environment. After the volume of the water in the sealing structure 400 reaches a preset volume, the water can overflow from the sealing structure 400 to enter the evaporation dish 130.

[0061] See also Figures 3 to 8 The lower end of the drain pipe 300 is arranged vertically, and the upper end of the drain pipe 300 is sealed and connected to the bottom of the refrigeration compartment, so that the water at the bottom of the refrigeration compartment can enter the drain pipe 300. A card groove 310 is formed on the outer periphery of the drain pipe 300.

[0062] In one embodiment, the clamping grooves 310 are arranged circumferentially. In another embodiment, a plurality of clamping grooves 310 are arranged at intervals around the axis of the drain pipe 300 .

[0063] The lower end of the drain pipe 300 is connected with a sealing structure 400, and the sealing structure 400 is detachably fixed to the lower end of the drain pipe 300. The outer periphery of the lower end of the drain pipe 300 is a circular structure, so that the sealing structure 400 can be conveniently sleeved on the drain pipe 300.

[0064] Fig. 9 It is a schematic diagram of the sealing structure of the utility model. Fig.10 It is a cross-sectional view of the sealing structure of the utility model. Fig.11It is a structural schematic diagram of the water holding tray of the utility model. Fig.12 It is a cross-sectional view of the water tray of the utility model.

[0065] See also Figures 3 to 12 The sealing structure 400 may include a water tray 410, which is fixed to the bottom end of the drain pipe 300 and faces the bottom end of the drain pipe 300, so that water in the drain pipe 300 can flow downward into the water tray 410. The water tray 410 is located directly above the evaporation dish 130, and the volume of the water tray 410 is smaller than the volume of the evaporation dish 130, so that water overflowing from the water tray 410 flows downward into the evaporation dish 130.

[0066] The water receiving tray 410 is provided with a water receiving chamber 411 with an open upper end; the lower end of the drain pipe 300 extends into the water receiving chamber 411 so that the water in the drain pipe 300 can enter the water receiving chamber 411. The lower end of the drain pipe 300 extends into the water receiving chamber 411 so that the bottom end of the drain pipe 300 is lower than the water receiving chamber 411, so that when there is a preset volume of water in the water receiving chamber 411, a liquid seal can be formed at the bottom end of the drain pipe 300.

[0067] In this embodiment, a sealing column 412 protruding upward is formed on the bottom wall of the water holding chamber 411. The sealing column 412 extends upward into the drain pipe 300. A gap for guiding water is provided between the outer peripheral side of the sealing column 412 and the inner wall of the drain pipe 300, so that the water in the drain pipe 300 can pass through the gap and the water holding chamber 411 in sequence and be discharged into the evaporation dish 130.

[0068] A guide channel 413 is provided on the sealing column 412, and the upper end of the sealing column 412 is higher than the bottom end of the drain pipe 300, so that a liquid seal can be formed between the inner side of the bottom end of the drain pipe 300 and the outer side of the sealing column 412 to ensure the sealing of the bottom end of the drain pipe 300.

[0069] In this embodiment, the upper end of the sealing column 412 is higher than the upper end of the water tray 410. When a liquid seal is formed between the water tray 410 and the drain pipe 300, since the upper end of the drain pipe 300 is connected to the refrigeration compartment, the refrigeration compartment is a closed structure, so that a negative pressure can be formed in the drain pipe 300, so that the liquid seal height in the drain pipe 300 is higher than the liquid level height in the water box. When the liquid seal height in the drain pipe 300 reaches the top of the sealing column 412, liquid water enters the guide channel 413 from the bottom of the sealing column 412, and is drained into the evaporation dish 130 through the guide channel 413.

[0070] The sealing ball 420 is placed and seals the upper end opening of the diversion channel 413, and the density of the sealing ball 420 is less than the density of water. When the liquid seal height in the drain pipe 300 is lower than the height of the sealing column 412, the sealing ball 420 seals the upper end of the diversion channel 413 to prevent gas from entering the drain pipe 300. When the liquid seal height in the drain pipe 300 reaches the height of the sealing column 412, the liquid water pushes the sealing ball 420 upward to allow the liquid water to enter the diversion channel 413. After the liquid water in the drain pipe 300 is lower than the seal height or is flush with the sealing column 412, the sealing ball 420 blocks and seals the upper end opening of the diversion channel 413.

[0071] In this embodiment, the guide channel 413 includes an upper channel 4131 and a lower channel 4132 from top to bottom, and the diameter of the upper channel 4131 is larger than the diameter of the lower channel 4132; the sealing ball 420 is against the top edge of the lower channel 4132, and the diameter of the sealing ball 420 is smaller than the diameter of the upper channel 4131, so that the sealing ball 420 can move up and down in the upper channel 4131, effectively preventing the sealing ball 420 from slipping out of the guide channel 413.

[0072] In some embodiments, the diameter of the flow guiding channel 413 at each position in the axial direction is the same. In other embodiments, the flow guiding channel 413 is an inverted cone structure.

[0073] In this embodiment, the edge of the lower end of the sealing column 412 extends radially to form a bottom plate 414, and the outer peripheral edge of the bottom plate 414 extends upward to form a circumferential plate 415; the circumferential plate 415 is arranged around the sealing column 412, and the outer peripheral side of the sealing column 412, the upper side of the bottom plate 414, and the inner side of the circumferential plate 415 enclose a water holding cavity 411.

[0074] The inner side surface of the circumferential plate 415 is located outside the bottom end of the drain pipe 300 , so that the projection of the bottom end of the drain pipe 300 is located in the water holding cavity 411 .

[0075] In this embodiment, the upper end of the circumferential plate 415 is lower than the upper end of the sealing column 412. In some embodiments, the upper end of the circumferential plate 415 is higher than the upper end of the sealing column 412 or is flush with the upper end of the sealing column 412.

[0076] The water tray 410 is provided with a fixing buckle 416. In this embodiment, the upper section of the circumferential plate 415 protrudes upward to form the fixing buckle 416. In one embodiment, the fixing buckle 416 protrudes upward from the bottom plate 414 to form.

[0077] The upper section of the circumferential plate 415 protrudes upward to form a fixing buckle 416 , and a plurality of fixing buckles 416 are arranged at intervals around the sealing column 412 .

[0078] Fig.13It is a schematic diagram of the blocking plug of the utility model.

[0079] See also Figures 4 to 13 The sealing ball 420 is located in the sealing column 412 and can move up and down in the sealing column 412. The sealing structure 400 also includes a blocking plug 430, which is fixed to the upper end of the sealing column 412 to limit the upward position of the sealing ball 420.

[0080] The water inlet 431 is opened on the peripheral side of the blocking plug 430 to ensure that the water in the drain pipe 300 can enter the diversion channel 413. In one embodiment, the water inlet 431 is opened at the upper end of the blocking plug 430.

[0081] In this embodiment, the lower end of the blocking plug 430 extends into and is fixed on the side wall of the guide channel 413. The blocking plug 430 is fixed on the sealing column 412 by means of threaded connection or clamping.

[0082] Fig.14 It is a structural schematic diagram of the adapter of the utility model. Fig.15 It is a cross-sectional view of the adapter of the utility model.

[0083] See also Figures 3 to 15 The sealing structure 400 also includes an adapter 440, which is fixed to the lower end of the drain pipe 300; a fixing buckle 416 is provided on the water receiving tray 410, and the fixing buckle 416 is engaged with the adapter 440 so that the water receiving tray 410 is fixed to the lower end of the drain pipe 300.

[0084] It should be noted that, in some embodiments, the sealing structure 400 does not include the adapter 440 , and the water tray 410 is directly fixed on the drain pipe 300 .

[0085] In this embodiment, the adapter 440 includes a sleeve 441 and a fixing ring 442; the sleeve 441 is sleeved and fixed on the outer circumference of the drain pipe 300, the fixing ring 442 is arranged around the sleeve 441 and connected to the outer circumference of the sleeve 441; the fixing buckle 416 is engaged with the fixing ring 442. The fixing buckle 416 is engaged with the fixing ring 442, so that the water tray 410 can be detachably engaged with the adapter 440, which facilitates the installation of the water tray 410.

[0086] In one embodiment, the adapter 440 only includes a sleeve 441 , and the fixing buckle 416 is engaged on the outer circumference of the sleeve 441 .

[0087] In this embodiment, a plurality of protruding connecting ribs 443 are formed on the outer periphery of the sleeve 441, and the plurality of connecting ribs 443 are arranged at intervals around the axis of the sleeve 441; the two ends of the connecting ribs 443 are respectively connected to the sleeve and the fixing ring 442, so that the adapter 440 is a whole.

[0088] A slot 310 is formed on the outer circumference of the drain pipe 300 , and a limit buckle is formed on the sleeve. The limit buckle is engaged in the slot 310 to limit the adapter 440 on the drain pipe 300 .

[0089] In this embodiment, a compressor and a condenser are arranged in the compressor chamber 120, and the condenser tube on the condenser extends into the evaporating dish 130, and the water tray 410 is located above the evaporating dish 130. When the condenser heats the liquid water in the evaporating dish 130, the liquid water in the water tray 410 will not be heated, and the hot air is effectively prevented from entering the refrigeration room through the drain pipe 300. At the same time, the sealing ball 420 seals the guide channel 413 on the sealing column 412, which can also prevent steam from entering the drain pipe 300 from the sealing structure 400.

[0090] In the present invention, a water tray 410 is fixed to the bottom end of the drain pipe 300, and the water tray 410 is provided with a water chamber 411 with an open top; a sealing column 412 protruding upward is formed on the bottom wall of the water chamber 411, and the sealing column 412 extends upward into the drain pipe 300, and a gap for guiding water is provided between the outer peripheral side of the sealing column 412 and the inner wall of the drain pipe 300, so that the water in the drain pipe 300 can pass through the gap and the water chamber 411 in sequence, and drain into the evaporation dish 130. The water in the drain pipe 300 first enters the water chamber 411 in the water tray 410, and the lower end of the drain pipe 300 extends into the water chamber 411, so that a liquid seal is formed between the water chamber 411 and the bottom end of the drain pipe 300. Since the upper end of the drain pipe 300 is connected to the refrigeration compartment, which is a closed chamber, negative pressure can be formed in the drain pipe 300 to maintain the liquid seal height of the drain pipe 300. The liquid seal of the drain pipe 300 is effectively maintained, and the refrigeration effect of the refrigeration compartment is effectively guaranteed.

[0091] The sealing column 412 is provided with a flow guide channel 413 which is through from top to bottom; and the upper end of the sealing column 412 is higher than the bottom end of the drain pipe 300; the sealing ball 420 is placed and seals the upper end opening of the flow guide channel 413, and the density of the sealing ball 420 is less than the density of water. When the height of the liquid seal in the drain pipe 300 is higher than the height of the sealing column 412, the sealing ball 420 can move upward so that the liquid in the drain pipe 300 can be discharged into the evaporation dish 130 through the flow guide channel 413. When the liquid level in the drain pipe 300 decreases, the sealing ball 420 descends to seal at the upper end of the flow guide channel 413. By setting the water chamber 411 and the sealing tube, the liquid seal of the drain pipe 300 can be effectively maintained, and the refrigeration effect of the refrigeration compartment can be effectively guaranteed.
