Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, preventing food or other items from spoiling by keeping them in a constant low temperature state.

[0003] In the related art, a refrigerator includes a freezer, a drawer and an evaporator, wherein the drawer and the evaporator are arranged in the freezer. The drawer is slidably connected to the housing, and the drawer is used to hold food or items to be preserved. The evaporator is used to cool the freezer. However, the evaporator is usually arranged on the top of the freezer or on the inner side of the rear wall of the freezer, which limits the height or depth of the drawer, resulting in a reduction in the volume of the drawer. Utility Model Content

[0004] The embodiment of the present application provides a refrigerator that can solve the technical problem of small volume of drawers in related refrigerators.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising an inner tank, an evaporator assembly and at least two drawers; the inner tank is formed with a refrigeration compartment; at least two drawers are slidably arranged in the refrigeration compartment in sequence along the height direction of the refrigerator; the evaporator assembly is arranged in the refrigeration compartment and is located between two adjacent drawers, the evaporator assembly comprises a shell, an evaporator and a fan; the shell is arranged between two adjacent drawers, the shell divides the refrigeration compartment into a first refrigeration compartment and a second refrigeration compartment from top to bottom, the shell is structured with a return air port and an air outlet, the first refrigeration compartment and the second refrigeration compartment are both connected to the return air port, the air outlet is arranged on a side of the shell facing the side wall of the inner tank, an air outlet gap is provided between the air outlet and the side wall of the inner tank, the first refrigeration compartment and the second refrigeration compartment are both connected to the air outlet gap; the evaporator is arranged in the shell; the fan is arranged in the shell.

[0006] The refrigerator of the embodiment of the present application reduces the space between the drawer and the rear wall of the inner container occupied by the evaporator assembly and reduces the space on the top of the inner container occupied by the evaporator assembly by arranging the evaporator assembly between two adjacent drawers, and increases the space in the inner container that can be used to arrange the drawer without changing the size of the inner container, thereby increasing the volume of the drawer and the volume of the refrigerator. In addition, by directing the air outlet of the evaporator assembly toward the side wall of the inner container and forming an air outlet gap between the air outlet and the side wall of the inner container, cold air is transported to the first refrigeration compartment and the second refrigeration compartment through the air outlet gap, so that the cold air is transported along the side wall of the inner container, and the space between the drawer and the rear wall of the inner container occupied by the cold air flow path can be reduced, thereby increasing the volume of the drawer.

[0007] In some embodiments of the present application, the inner liner has a first side wall and a second side wall arranged opposite to each other; the air outlet includes a first air outlet and a second air outlet, the air outlet direction of the first air outlet is toward the first side wall, and the air outlet direction of the second air outlet is toward the second side wall.

[0008] With such an arrangement, the cold air in the outer shell can be blown out from both the first air outlet and the second air outlet, so that the cold air can circulate at both side walls of the inner tank, thereby improving the refrigeration efficiency of the refrigeration compartment and the drawer, reducing the temperature difference at both ends of the drawer along the width direction of the refrigerator, and improving the temperature uniformity in the drawer.

[0009] In some embodiments of the present application, a heat exchange chamber and an air outlet chamber that are connected are constructed in the shell, the air outlet chamber is located on the side of the heat exchange chamber, the evaporator is arranged in the heat exchange chamber, the return air port is connected to the heat exchange chamber, and the air outlet is connected to the air outlet chamber.

[0010] In this way, the space in the shell is divided into a heat exchange chamber and an air outlet chamber, and the air from the first refrigeration compartment and the second refrigeration compartment exchanges heat with the evaporator in the heat exchange chamber. Compared with the space in the shell without division, since the volume of the heat exchange chamber is smaller than the total volume of the shell, the density of the same amount of air in the heat exchange chamber is greater than that in the shell, and the heat exchange efficiency between the air in the heat exchange chamber and the heat exchanger is greater than that between the air in the shell. Therefore, the space in the shell is divided into a heat exchange chamber and an air outlet chamber, and the evaporator is arranged in the heat exchange chamber, which can improve the refrigeration efficiency of the air from the first refrigeration compartment and the second refrigeration compartment. The air outlet chamber can be located on the side of the heat exchange chamber, that is, the air outlet chamber is located on one side of the heat exchange chamber in the horizontal direction, so as to reduce the length of the shell along the height direction of the refrigerator and reduce the height of the refrigeration compartment occupied by the shell, thereby increasing the volume of the drawer and increasing the volume of the refrigerator.

[0011] In some embodiments of the present application, the return air outlet is connected to an end of the heat exchange chamber facing away from the air outlet chamber.

[0012] This arrangement can increase the length of the air flow path from the return air port to the air outlet chamber, thereby improving the heat exchange efficiency between the evaporator and the air.

[0013] In some embodiments of the present application, the return air outlet includes a first return air outlet and a second return air outlet, the first return air outlet is arranged at the top of the shell, and the second return air outlet is arranged at the bottom of the shell.

[0014] With such arrangement, the air in the first refrigeration room can enter the housing through the first return air port, and the air in the second refrigeration room can enter the housing through the second return air port.

[0015] In some embodiments of the present application, a connecting port is configured between the heat exchange chamber and the air outlet chamber, and the heat exchange chamber and the air outlet chamber are connected through the connecting port; and the fan is arranged at the connecting port.

[0016] With this arrangement, part of the fan is located in the heat exchange chamber, and part of the fan is located in the air outlet chamber, thereby increasing the air circulation rate in the heat exchange chamber and the air outlet chamber.

[0017] In some embodiments of the present application, the fan is spaced apart from the bottom surface of the casing.

[0018] This arrangement can reduce the contact between the fan and the defrost water of the evaporator, making it difficult for the fan to be damaged by water. It can also reduce the possibility of the fan throwing water out to the air outlet and then causing water to enter the refrigeration compartment.

[0019] In some embodiments of the present application, the outer shell is inclined relative to a horizontal plane, and an end of the outer shell close to the rear wall of the inner tank is closer to the bottom of the inner tank than an end away from the rear wall of the inner tank; a water collection chamber is constructed in the outer shell, and the water collection chamber is located at an end of the outer shell close to the rear wall of the inner tank; the evaporator assembly also includes a drain member, which is connected to the outer shell and communicates with the water collection chamber.

[0020] With such arrangement, the defrost water generated when the evaporator defrosts drops to the bottom of the shell. Since the shell is inclined, the defrost water gathers in the water collecting chamber along the inclined bottom surface of the shell and is discharged to the outside of the shell through the drainage piece.

[0021] In some embodiments of the present application, the refrigerator includes a cabinet, an evaporating dish and a compressor; a press chamber is defined in the cabinet; the evaporating dish is arranged in the press chamber, and the water outlet of the drainage member extends into the evaporating dish; the compressor is arranged in the press chamber, the compressor has an air outlet pipe, and part of the air outlet pipe is arranged in the evaporating dish.

[0022] With such arrangement, the temperature of the compressor outlet pipe is relatively high, and the defrost water in the evaporating dish is evaporated by the high temperature of the outlet pipe, so that the defrost water can be processed.

[0023] In a second aspect, an embodiment of the present application provides a refrigerator, comprising an inner tank, an evaporator assembly and at least two drawers; the inner tank is formed with a refrigeration compartment; at least two drawers are slidably arranged in the refrigeration compartment in sequence along the height direction of the refrigerator; the evaporator assembly comprises an outer shell, an evaporator and a fan, the evaporator and the fan are arranged in the outer shell, the outer shell is arranged between two adjacent drawers, the outer shell is constructed with a return air port and an air outlet, the return air port is connected to the refrigeration compartment, the air outlet is arranged on a side of the outer shell facing the side wall of the inner tank, an air outlet gap is provided between the air outlet and the side wall of the inner tank, and the air outlet gap is connected to the refrigeration compartment.

[0024] The refrigerator of the embodiment of the present application reduces the space between the drawer and the rear wall of the inner container occupied by the evaporator assembly and reduces the space on the top of the inner container occupied by the evaporator assembly by arranging the evaporator assembly between two adjacent drawers, and increases the space in the inner container that can be used to arrange the drawer while keeping the size of the inner container unchanged, thereby increasing the volume of the drawer and the volume of the refrigerator. In addition, by directing the air outlet of the evaporator assembly toward the side wall of the inner container and forming an air outlet gap between the air outlet and the side wall of the inner container, cold air is transported to the refrigeration compartment above the outer shell and the refrigeration compartment below the outer shell through the air outlet gap, so that the cold air is transported along the side wall of the inner container, and the space between the drawer and the rear wall of the inner container occupied by the cold air flow path can be reduced, thereby increasing the volume of the drawer.

[0061] As described in the background technology, the refrigerator in the related art has the problem of small drawer volume. The inventor has found that the reason for this problem is that the evaporator of the refrigerator in the related art is arranged on the top of the freezer liner or on the inner side of the rear wall of the freezer liner. When the evaporator is arranged on the top of the freezer liner, the height of the drawer will be limited, resulting in a reduction in the volume of the drawer. When the evaporator is arranged on the inner side of the rear wall of the freezer liner, the depth of the drawer will be limited, resulting in a reduction in the volume of the drawer.

[0062] In view of this, the refrigerator of the embodiment of the present application reduces the space between the drawer and the rear wall of the inner tank occupied by the evaporator assembly and reduces the space on the top of the inner tank occupied by the evaporator assembly by arranging the evaporator assembly between two adjacent drawers, and increases the space in the inner tank that can be used to arrange the drawer while keeping the size of the inner tank unchanged, thereby increasing the volume of the drawer and the volume of the refrigerator. In addition, by directing the air outlet of the evaporator assembly toward the side wall of the inner tank and forming an air outlet gap between the air outlet and the side wall of the inner tank, cold air is transported to the refrigeration compartment above the shell and the refrigeration compartment below the shell through the air outlet gap, so that the cold air is transported along the side wall of the inner tank, and the space between the drawer and the rear wall of the inner tank occupied by the cold air flow path can be reduced, thereby increasing the volume of the drawer.

The top wall 14 and the bottom wall 15 are opposite, the top wall 14 is located at the top of the inner tank 1, and the bottom wall 15 is located at the bottom of the inner tank 1. The two side walls 17 are opposite, and the two side walls 17 are respectively located on both sides of the inner tank 1 along the width direction X of the refrigerator. The inner tank 1 is surrounded by the rear wall 13, the top wall 14, the bottom wall 15 and the two side walls 17 to form a refrigeration compartment 11.

[0074] refer to Figure 2-Figure 8 The refrigerator may further include an evaporator assembly 3. The evaporator assembly 3 includes a shell 31. The shell 31 is disposed in the inner container 1. The side of the shell 31 facing the rear wall 13 may be connected to the rear wall 13, and the side of the shell 31 facing the side wall 17 may be connected to the side wall, so as to connect the shell 31 to the inner container 1.

[0075] The housing 31 divides the refrigerating compartment 11 into a first refrigerating compartment 111 and a second refrigerating compartment 112. The first refrigerating compartment 111 may be located above the housing 31. The second refrigerating compartment 112 may be located below the housing 31.

[0076] In some possible embodiments, the housing 31 may be configured with a return air port 321 .

[0077] In some possible implementations of the present application, reference is made to Figure 4 The return air vent 321 may include a first return air vent 322 and a second return air vent 323. The first return air vent 322 may be disposed at the top of the housing 31, that is, the side of the housing 31 facing the first refrigeration compartment 111. The second return air vent 323 may be disposed at the bottom of the housing 31, that is, the side of the housing 31 facing the second refrigeration compartment 112.

[0078] The air in the first refrigeration compartment 111 can enter the housing 31 through the first return air port 322 , and the air in the second refrigeration compartment 112 can enter the housing 31 through the second return air port 323 .

[0079] In some other possible implementations of the embodiment of the present application, the return air vent 321 can be constructed on a side of the shell 31 away from the rear wall 13 of the inner tank 1, the first refrigeration chamber 111 and the second refrigeration chamber 112 are both connected to the return air vent 321, and the air in the first refrigeration chamber 111 and the second refrigeration chamber 112 can enter the shell 31 through the return air vent 321.

[0080] In some possible embodiments, reference Figure 5 The housing 31 may be configured with an air outlet 331 .

[0081] The air outlet 331 is disposed on a side of the shell 31 facing the side wall 17 of the inner container 1 . An air outlet gap 12 is defined between the air outlet 331 and the side wall 17 of the inner container 1 . The first refrigeration chamber 111 and the second refrigeration chamber 112 are both connected to the air outlet gap 12 .

[0082] The air in the shell 31 is blown out from the air outlet 331 to the air outlet gap 12. After the air entering the air outlet gap 12 collides with the side wall 17 of the inner liner 1, part of the air flows upward along the side wall 17 of the inner liner 1 into the first refrigeration chamber 111, and the other part of the air flows downward along the side wall 17 of the inner liner 1 into the second refrigeration chamber 112.

[0083] In some possible embodiments, reference Figure 4-Figure 6 The evaporator assembly 3 may include a fan 36 disposed in the housing 31. The fan 36 is used to allow air in the first refrigeration compartment 111 and the second refrigeration compartment 112 to flow into the housing 31 from the return air port 321 and flow out of the housing 31 from the air outlet 331.

[0084] In some possible embodiments, reference Figure 4-Figure 6 The evaporator assembly 3 may include an evaporator 35, and the evaporator 35 is disposed in the housing 31. The evaporator 35 may be disposed on the flow path of the air flowing from the return air port 321 to the air outlet 331.

[0085] refer to Figure 4-Figure 6 When the refrigerator is in cooling mode, the fan 36 works, and the air in the first refrigeration compartment 111 and the second refrigeration compartment 112 enters the housing 31 from the return air port 321, exchanges heat with the evaporator 35 when passing through the evaporator 35, so that the temperature of the air is reduced, and then is blown out from the air outlet 331 to the air outlet gap 12. After the air entering the air outlet gap 12 collides with the side wall 17 of the inner tank 1, a part of the air flows upward along the side wall 17 of the inner tank 1 to the first refrigeration compartment 111, and the other part of the air flows downward along the side wall 17 of the inner tank 1 to the second refrigeration compartment 112, and the cycle is repeated to adjust the temperature in the first refrigeration compartment 111 and the second refrigeration compartment 112.

[0086] In some possible embodiments, reference Figure 7 and Figure 8 The housing 31 may include a shell 311 and a cover plate 312. The top of the shell 311 may have an opening, and the cover plate 312 covers the shell 311 to close the shell 311. The first return air outlet 322 may be provided on the cover plate 312, and the second return air outlet 323 may be provided at the bottom of the shell 311.

[0087] The shell 311 and the cover plate 312 may be detachably connected to facilitate assembly of the fan 36 and the evaporator 35 in the housing 31 .

[0088] In some possible embodiments, the refrigerator may include at least two drawers 2, wherein at least one drawer 2 may be disposed in the first refrigeration compartment 111, and the other drawers 2 may be disposed in the second refrigeration compartment 112. A flow channel may be provided between the drawers 2 and the side walls 17 of the inner container 1 on both sides along the width direction X of the refrigerator.

[0089] refer to Figure 5 , the air in the shell 31 is blown out from the air outlet 331 to the air outlet gap 12. After the air entering the air outlet gap 12 collides with the side wall 17 of the inner liner 1, part of the air flows upward along the side wall 17 of the inner liner 1, and flows upward along the gap between the side wall 17 of the inner liner 1 and the drawer 2 to the top of the drawer 2 to adjust the temperature in the drawer 2. Another part of the air flows downward along the side wall 17 of the inner liner 1 to the second refrigeration chamber 112, and flows downward along the gap between the side wall 17 of the inner liner 1 and the drawer 2 to the bottom of the drawer 2 to cool the drawer 2 below the shell 31.

[0090] The refrigerator of the embodiment of the present application sets the evaporator assembly 3 between two adjacent drawers 2, reducing the space occupied by the evaporator assembly 3 between the drawer 2 and the rear wall 13 of the inner tank 1, and reducing the space occupied by the evaporator assembly 3 on the top of the inner tank 1. When the size of the inner tank 1 remains unchanged, the space in the inner tank 1 that can be used to set the drawer 2 is increased, thereby increasing the volume of the drawer 2 and increasing the volume of the refrigerator.

[0091] In addition, by directing the air outlet 331 of the evaporator assembly 3 toward the side wall 17 of the inner tank 1 and forming an air outlet gap 12 between the air outlet 331 and the side wall 17 of the inner tank 1, cold air is transported to the first refrigeration chamber 111 and the second refrigeration chamber 112 through the air outlet gap 12, so that the cold air is transported along the side wall 17 of the inner tank 1. Compared with the cold air being transmitted along the rear wall 13 of the inner tank 1, the space occupied by the cold air flow path between the drawer 2 and the rear wall of the inner tank 1 can be reduced, thereby increasing the volume of the drawer 2.

[0092] In some possible embodiments, reference Figure 3 and Figure 5The inner container 1 may have a first side wall 171 and a second side wall 172 that are arranged opposite to each other, and the first side wall 171 and the second side wall 172 are respectively located on both sides of the inner container 1 along the width direction X of the refrigerator.

[0093] The air outlet 331 may include a first air outlet 332, and the air outlet direction of the first air outlet 332 may be toward the first side wall 171. The cold air in the shell 31 is blown out from the first air outlet 332 to the air outlet gap 12 between the first air outlet 332 and the first side wall 171. After the air entering the air outlet gap 12 collides with the first side wall 171, part of the air flows upward along the first side wall 171 into the first refrigeration chamber 111, and the other part of the air flows downward along the first side wall 171 into the second refrigeration chamber 112.

[0094] The air outlet 331 may include a second air outlet 333, and the air outlet direction of the second air outlet 333 may be toward the second side wall 172. The cold air in the shell 31 is blown out from the second air outlet 333 to the air outlet gap 12 between the second air outlet 333 and the second side wall 172. After the air entering the air outlet gap 12 collides with the second side wall 172, part of the air flows upward along the second side wall 172 into the first refrigeration chamber 111, and the other part of the air flows downward along the second side wall 172 into the second refrigeration chamber 112.

[0095] In the implementation mode in which the air outlet 331 includes the first air outlet 332 and the second air outlet 333, the cold air in the outer shell 31 can be blown out from the first air outlet 332 and the second air outlet 333, so that cold air can flow through the two side walls 17 of the inner tank 1, thereby improving the refrigeration efficiency of the refrigeration compartment 11 and the drawer 2, reducing the temperature difference at both ends of the drawer 2 along the width direction X of the refrigerator, and improving the uniformity of the temperature in the drawer 2.

[0096] In some possible embodiments, reference Figure 4-Figure 7 A heat exchange chamber 32 and an air outlet chamber 33 may be constructed in the housing 31. The heat exchange chamber 32 and the air outlet chamber 33 are connected. The evaporator 35 is disposed in the heat exchange chamber 32. The return air port 321 is connected to the heat exchange chamber 32. The air outlet 331 is connected to the air outlet chamber 33.

[0097] The fan 36 may be disposed in the heat exchange chamber 32 or the air outlet chamber 33. Alternatively, the fan 36 may be disposed at a communication position between the heat exchange chamber 32 and the air outlet chamber 33.

[0098] When the fan 36 is working, the air in the first refrigeration chamber 111 and the second refrigeration chamber 112 flows into the heat exchange chamber 32 from the return air port 321 , exchanges heat with the evaporator 35 , flows to the air outlet chamber 33 , and returns to the first refrigeration chamber 111 and the second refrigeration chamber 112 from the air outlet 331 .

[0099] The space in the shell 31 is divided into a heat exchange chamber 32 and an air outlet chamber 33, and the air from the first refrigeration chamber 111 and the second refrigeration chamber 112 exchanges heat with the evaporator 35 in the heat exchange chamber 32. Compared with the case where the space in the shell 31 is not divided, since the volume of the heat exchange chamber 32 is smaller than the total volume of the shell 31, the density of the same amount of air in the heat exchange chamber 32 is greater than that in the shell 31, and the heat exchange efficiency between the air in the heat exchange chamber 32 and the heat exchanger is greater than that between the air in the shell 31. Therefore, the space in the shell 31 is divided into the heat exchange chamber 32 and the air outlet chamber 33, and the evaporator 35 is arranged in the heat exchange chamber 32, which can improve the cooling efficiency of the air from the first refrigeration chamber 111 and the second refrigeration chamber 112.

[0100] In some possible embodiments, the air outlet chamber 33 can be located on the side of the heat exchange chamber 32, that is, the air outlet chamber 33 is located on one side of the heat exchange chamber 32 in the horizontal direction, so as to reduce the length of the outer shell 31 along the height direction Y of the refrigerator, and reduce the height of the refrigeration chamber 11 occupied by the outer shell 31, thereby increasing the volume of the drawer 2 and increasing the volume of the refrigerator.

[0101] In some possible embodiments, the return air port 321 may be connected to one end of the heat exchange chamber 32 away from the air outlet chamber 33 to increase the length of the air flow path from the return air port 321 to the air outlet chamber 33, thereby improving the heat exchange efficiency between the evaporator 35 and the air.

[0102] In some possible embodiments, reference Figure 7 and Figure 8 A communication port 335 may be configured between the heat exchange chamber 32 and the air outlet chamber 33 . The heat exchange chamber 32 and the air outlet chamber 33 are connected through the communication port 335 .

[0103] A first partition 336 may be provided in the housing 31, and the first partition 336 divides the space in the housing 31 into a heat exchange chamber 32 and an air outlet chamber 33. A communication port 335 may be provided on the first partition 336. The heat exchange chamber 32 and the air outlet chamber 33 communicate with each other through the communication port 335.

[0104] The fan 36 can be arranged at the connecting port 335 , so that part of the fan 36 is located in the heat exchange chamber 32 and part of the fan 36 is located in the air outlet chamber 33 , thereby improving the air circulation rate in the heat exchange chamber 32 and the air outlet chamber 33 .

[0105] In some possible implementations of the embodiments of the present application, one end of the first partition 336 close to the connecting port 335 can be bent toward the air outlet chamber 33 to form a bending plate 337. The bending plate 337 can guide the air flowing from the heat exchange chamber 32 to the air outlet chamber 33 to increase the air circulation rate.

[0106] In some possible implementations of the embodiment of the present application, a second partition 324 may be provided in the heat exchange chamber 32, and the second partition 324 may extend in a direction from the heat exchange chamber 32 to the air outlet chamber 33. The second partition 324 is located at the periphery of the evaporator 35. One end of the second partition 324 facing away from the air outlet chamber 33 may be connected to the inner side of the housing 31. One end of the second partition 324 close to the air outlet chamber 33 may be connected to the first partition 336. One end of the second partition 324 close to the air outlet chamber 33 may be spaced apart from the first partition 336.

[0107] The second partition 324 reduces the space of the heat exchange chamber 32 occupied by the evaporator 35 , and increases the density of the air flowing through the evaporator 35 while the amount of air entering through the return air port 321 remains unchanged, thereby increasing the heat exchange efficiency between the air and the evaporator 35 .

[0108] In some possible embodiments, reference Figure 4 and Figure 7 The fan 36 and the bottom surface of the housing 31 can be spaced apart to reduce the contact between the fan 36 and the defrosting water of the evaporator 35, so that the fan 36 is not easily damaged by water, and the possibility of the fan 36 throwing water out to the air outlet 331 and then causing water to enter the refrigeration chamber 11 can be reduced.

[0109] In some possible implementations of the present application, a door body (not shown in the drawings) may be provided on the side of the drawer 2 facing away from the rear wall 13 of the inner tank 1. A middle crossbeam 18 may be provided in the inner tank 1, and the middle crossbeam 18 may be located at one end of the outer shell 31 facing away from the rear wall 13 of the inner tank 1, and the middle crossbeam 18 is used to cooperate with the door body of the drawer 2 to seal the refrigeration compartment 11.

[0110] The outer shell 31 is hidden behind the middle cross beam 18 to utilize the space behind the middle cross beam 18, reduce the space occupied by the evaporator assembly 3 between the drawer 2 and the rear wall 13 of the inner tank 1, and reduce the space occupied by the evaporator assembly 3 on the top of the inner tank 1. When the size of the inner tank 1 remains unchanged, the space in the inner tank 1 that can be used to set the drawer 2 is increased, thereby increasing the volume of the drawer 2 and increasing the volume of the refrigerator.

[0111] In some possible implementations of the present application, reference is made to Figure 4 The outer shell 31 can be tilted relative to the horizontal plane. One end of the outer shell 31 close to the rear wall 13 of the inner container 1 is closer to the bottom wall 15 of the inner container 1 than the end away from the rear wall 13 of the inner container 1.

[0112] A water collecting chamber 34 may be constructed in the outer shell 31 . The water collecting chamber 34 may be located at one end of the outer shell 31 close to the rear wall 13 of the inner tank 1 . The water collecting chamber 34 is used to collect defrost water from the evaporator 35 .

[0113] A heat exchange chamber 32 and an air outlet chamber 33 are constructed in the outer shell 31. In the implementation method in which the air outlet 331 includes a first air outlet 332 and a second air outlet 333, the heat exchange chamber 32 can be located on the side of the air outlet chamber 33 away from the rear wall 13 of the inner tank 1, and the water collecting chamber 34 can be surrounded by two guide plates 341 arranged in the outer shell 31. The guide plates 341 can be extended from the fan 36 to the air outlet 331, and there is a gap between the ends of the two guide plates 341 that are close to each other. The two guide plates 341 and the side wall 17 of the outer shell 31 are surrounded by the water collecting chamber 34, and the water collecting chamber 34 and the air outlet chamber 33 are connected to each other through the gap between the two guide plates 341.

[0114] The return air port 321 is located at one end of the heat exchange chamber 32 away from the air outlet chamber 33 , so that the height of the return air port 321 is greater than the height of the end of the heat exchange chamber 32 close to the air outlet chamber 33 , making it difficult for defrost water of the evaporator 35 to flow from the second return air port 323 into the second refrigeration chamber 112 .

[0115] refer to Figure 7 and Figure 8 The evaporator assembly 3 further includes a drain member 37 , which is connected to the housing 31 and communicates with the water collecting chamber 34 .

[0116] The drainage component 37 may be a drainage pipe or a drainage nozzle, etc. The drainage component 37 is used to drain the water in the water collection chamber 34 .

[0117] refer to Figure 4 and Figure 5 A through hole 19 may be provided on the rear wall 13 of the inner pot 1, and a drainage member 37 is passed through the through hole so that an end of the drainage member 37 facing away from the outer shell 31 is extended to the outside of the inner pot 1, thereby facilitating the discharge of defrost water.

[0118] When the evaporator 35 defrosts, defrost water is generated, and the defrost water drips to the bottom of the shell 31. Since the shell 31 is inclined, the defrost water is collected in the water collecting chamber 34 along the inclined bottom surface of the shell 31, and is discharged to the outside of the shell 31 through the drain 37.

[0119] In some possible implementations of the embodiments of the present application, the end of the drainage member 37 can be led out of the refrigerator to facilitate the discharge of the defrost water.

[0120] In some other possible implementations of the embodiments of the present application, refer to Figure 1 , Figure 4 , Fig. 9 and Fig.10 The refrigerator may further include a box body 4. The inner tank 1 is arranged in the box body 4. A press chamber 41 is defined in the box body 4.

[0121] The refrigerator may further include an evaporating dish 5, which is disposed in the press chamber 41. The water outlet of the drainage member 37 may extend into the evaporating dish 5, and the defrost water of the evaporator 35 is guided into the evaporating dish 5 through the drainage member 37, and the evaporating dish 5 collects the defrost water.

[0122] The refrigerator may also include a compressor (not shown in the drawings), which is arranged in the compressor compartment 41. The compressor has an air outlet pipe, which is used to connect the compressor and the condenser of the refrigerator. The compressor compresses the refrigerant into high-temperature and high-pressure gas, which flows from the air outlet pipe to the condenser, so the temperature of the air outlet pipe is relatively high. Part of the air outlet pipe is arranged in the evaporating dish 5, so that the defrosting water in the evaporating dish 5 can be evaporated by the high temperature of the air outlet pipe.
