[0076] The refrigerator is a refrigeration equipment, which can keep the food or other articles placed inside at low temperature. The refrigerator is provided with an evaporator and a fan, and is configured to form an evaporating chamber and an air duct. The evaporator is installed in the evaporating chamber, and the fan is installed in the air duct. The fan drives the air to circulate between the evaporating chamber and the storage compartment, thereby reducing the temperature of the storage compartment.

[0077] In some refrigerators, for example, drawer type refrigerators, the freezing compartment is closed by two drawer type doors, which can provide a larger storage volume. However, a middle cross beam is necessarily arranged between the two drawers to improve the overall stability of the refrigerator and prevent the drawers from deforming due to frequent opening and closing. However, the space behind the middle cross beam is not effectively utilized.

[0078] Therefore, the present application research and development personnel set the evaporator module at the rear side of the middle cross beam, and heat exchange refrigeration is performed on the space above and below the middle cross beam, respectively. The evaporator module is configured to form an evaporating chamber, and an evaporator is installed in the evaporating chamber.

[0079] Since the space behind the middle cross beam is small in the height direction, the air duct is usually arranged at the rear side of the box body and extends in the height direction of the refrigerator to blow air to the space above and below the middle cross beam, respectively.

[0080] The present application research and development personnel found that there is a problem of air leakage between the shell forming the evaporating chamber and the air duct shell forming the air duct, which affects the refrigeration efficiency and also causes the refrigerator to increase. Moreover, since the shell is also configured to form a drainage structure to drain the defrosting water of the evaporator. Due to the poor sealing between the shell and the air duct shell, there is a water seepage condition at the bottom of the shell.

[0081] Therefore, the present application research and development personnel set a first sealing member between the shell and the air duct shell to improve the sealing between the shell and the air duct shell, and improve the sealing between the evaporating chamber and the air duct.

[0082] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0083] First of all, it should be noted that, in combination with Figure 1 , the width direction of the refrigerator corresponds to the X-axis direction in the figure, the depth direction of the refrigerator corresponds to the Y-axis direction in the figure, and the height direction of the refrigerator corresponds to the Z-axis direction in the figure.

[0084] In combination with Figure 1 , some embodiments of the present application provide a refrigerator, which includes a cabinet 10, and the cabinet 10 can be configured to form a storage compartment 101 with a front opening for storing articles. In Figure 1 , the negative side of the Y-axis direction is the front side.

[0085] The storage compartment 101 can be provided in multiple numbers to expand the storage space. According to different storage temperatures of the storage compartment 101, the storage compartment 101 can include at least one refrigeration compartment and at least one freezing compartment. The internal temperature of the refrigeration compartment can be maintained at about 0℃ to 5℃ to store articles in a refrigeration mode, and the internal temperature of the freezing compartment can be maintained at about -30℃ to 0℃ to store articles in a freezing mode.

[0086] In some possible implementations, at least one storage compartment 101 can also be provided as a vacuum chamber or a variable-temperature chamber, and the like, and the embodiments of the present application will not be described again.

[0087] Exemplarily, the storage compartment 101 can be provided in two numbers, and the two storage compartments 101 can be arranged in a vertical direction in a stacked manner or arranged in a horizontal direction in a side-by-side manner. One of the two storage compartments 101 can be provided as a refrigeration compartment, and the other one can be provided as a freezing compartment.

[0088] In some embodiments, the cabinet 10 can include a cabinet liner 11 and a cabinet shell. The cabinet liner 11 can be configured to form the storage compartment 101 with a front opening. The cabinet shell can be connected to the outside of the cabinet liner 11 to form the appearance of the refrigerator.

[0089] The cabinet 10 can further include a cabinet insulation layer, which can be arranged between the cabinet liner 11 and the cabinet shell. The cabinet insulation layer can thermally insulate the storage compartment 101 to minimize the heat exchange between the storage compartment 101 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0090] The refrigerator of the embodiments of the present application can further comprise a refrigerating system for providing cold energy to the storage compartment 101. Exemplarily, the refrigerating system can be arranged in the cabinet 10. The refrigerating system can comprise a compressor, a condenser, a throttling device and an evaporator connected in a circulation.

[0091] When the refrigerating system is running, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and delivers the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid, and delivers the refrigerant liquid to the throttling device. The throttling device depressurizes the refrigerant liquid to change the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid, and delivers the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid, and makes it boil under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, so as to reduce the temperature in the storage compartment 101.

[0092] With reference to the foregoing Figure 1 The refrigerator of the embodiments of the present application can further comprise a door body 20 rotatably connected to the cabinet 10 to open or close the storage compartment 101.

[0093] Each storage compartment 101 can correspondingly be provided with one door body 20, or each storage compartment 101 can correspondingly be provided with two door bodies 20, and the two door bodies 20 can rotate in opposite directions to open or close the storage compartment 101.

[0094] Of course, in some possible implementations, a drawer is arranged in the storage compartment 101, and an outer end of the drawer is configured to form the door body 20.

[0095] In some embodiments, the door body 20 can comprise a door inner liner. When the door body 20 closes the refrigerating compartment, the door inner liner faces the refrigerating compartment.

[0096] The door body 20 can comprise a door outer shell. The door outer shell can be connected to an outer side of the door inner liner to form an appearance of the door body 20. The door outer shell can be rotatably connected to the cabinet 10 to open or close the refrigerating compartment.

[0097] The door body 20 can further comprise a door thermal insulation member arranged in a space between the door inner liner and the door outer shell. The door thermal insulation member can thermally insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator. The door thermal insulation member can be a foaming layer.

[0098] In some embodiments, a door shelf is arranged on a side of the door body 20 facing the refrigerating compartment to increase the storage position of the refrigerator. The door shelf has a storage cavity with an opening upward to store articles.

[0099] With reference to the foregoing Figure 2 and Figure 3In some embodiments of the present application, the front side of the box body 11 is fixed with a middle beam 12 to improve the structure of the box body 11 to provide support and stability, and to prevent the box 10 from deforming.

[0100] The middle beam 12 can be fixed to the box body 11 in various ways, including but not limited to screw fixing, clamping, etc.

[0101] In combination with Figure 3 and Figure 4 , the refrigerator of the embodiments of the present application further comprises an evaporator module 30 configured to reduce the temperature of the storage compartment 101.

[0102] The evaporator module 30 is fixed inside the box body 11 and located at the rear side of the middle beam 12, so that the evaporator module 30 can utilize the space at the rear side of the middle beam 12.

[0103] The evaporator module 30 is located inside the box body 11 and divides the storage compartment 101 into a first storage cavity 1011 and a second storage cavity 1012, wherein the first storage cavity 1011 is located at the top of the evaporator module 30 and the second storage cavity 1012 is located at the bottom of the evaporator module 30.

[0104] In this way, storage cavities are formed above and below the evaporator module 30, which can store different types of food and improve the flexibility of the storage cavities.

[0105] In the embodiments of the present application, the evaporator module 30 is configured to reduce the temperature of the first storage cavity 1011 and the second storage cavity 1012. The evaporator module 30 is located inside the box body 11, which can shorten the circulation path of the cold air and be beneficial to reduce the heat loss during the flow of the cold air.

[0106] In some embodiments, the evaporator module 30 is arranged in the freezer box body, and the refrigerator can be configured with an air duct 502, so that the evaporator module 30 cools the refrigeration compartment of the refrigeration box body. The refrigerator is provided with only one evaporator, which is beneficial to reduce the cost. Alternatively, the refrigerator can be additionally provided with an evaporator for cooling the refrigeration compartment of the refrigeration box body, which can improve the accuracy of temperature control of the refrigeration compartment and the freezing compartment.

[0107] Continuing to refer to Figure 4 In some embodiments, at least one first drawer 13 is arranged in the first storage cavity 1011, and the first drawer 13 is pullable in the depth direction of the refrigerator (corresponding to the Figure 4 middle Y-axis direction), which facilitates the taking and placing of articles.

[0108] In some embodiments of the present application, the first drawer 13 is spaced apart from the housing member 100 in the height direction of the refrigerator, so that a space is formed between the bottom surface of the first drawer 13 and the evaporator module 30, thereby preventing the evaporator module 30 from causing the first drawer 13 to be excessively cooled.

[0109] The second storage cavity 1012 is provided with at least one second drawer 14, which is pullable in the depth direction (corresponding to the Figure 4 Y-axis direction) of the refrigerator, facilitating the taking and placing of articles.

[0110] In some implementations, the first drawer 13 and / or the second drawer 14 can be further provided with an inner drawer 15. For example, the second drawer 14 is provided with an inner drawer 15, which is located above the second drawer 14. The inner drawer 15 is not exposed when the second drawer 14 is closed, and the inner drawer 15 can be opened along with the opening of the second drawer 14, so as to increase the storage space and facilitate the flexibility of article storage.

[0111] As Figure 4 shown, in some embodiments of the present application, the evaporator module 30 includes a housing member 100 and an evaporator 200. The housing member 100 is configured to form an evaporation chamber 301, and the evaporator 200 is fixed in the evaporation chamber 301. The front side of the evaporation chamber 301 is in communication with the first storage cavity 1011 and the second storage cavity 1012, respectively, so that the air in the first storage cavity 1011 and the second storage cavity 1012 can exchange heat with the evaporator 200 in the evaporation chamber 301.

[0112] The housing member 100 is located at the rear side of the middle cross beam 12, so that the evaporator module 30 can utilize the space at the rear side of the middle cross beam 12. The housing member 100 can be fixed to the middle cross beam 12, for example, the housing member 100 is fixed to the middle cross beam 12 by screws, which is stable and reliable; for another example, the housing member 100 is clamped to the middle cross beam 12, which facilitates the on-site assembly of the evaporator module 30.

[0113] In combination Figure 4 and Figure 5 , in some embodiments, the housing member 100 includes:

[0114] an upper cover 110 located above the evaporator 200.

[0115] a lower cover 120 located below the evaporator 200. The rear end of the lower cover 120 can be inclined downward, facilitating the collection and discharge of defrost water of the evaporator 200.

[0116] The upper cover 110 and the lower cover 120 are clamped on both sides along the width direction of the refrigerator, so that the upper cover 110 and the lower cover 120 are stably connected. At least one of the upper cover 110 and the lower cover 120 is fixedly connected with the middle beam 12, so as to realize the fixed connection of the shell piece 100 and the middle beam 12. The shell piece 100 of the embodiment of the application is clamped by the upper cover 110 and the lower cover 120, which facilitates the disassembly and assembly of the internal evaporator 200.

[0117] In some embodiments of the application, in combination Figure 4 The front side of the shell piece 100 is configured to form a first return air inlet 302, and the first return air inlet 302 is in communication with the first storage cavity 1011.

[0118] The first return air inlet 302 can include a plurality of openings arranged at intervals along the width direction of the refrigerator, forming a grating shape, which can have a larger area of the first return air inlet 302 and can also shield the structure in the evaporation chamber 301.

[0119] The front side of the shell piece 100 is also configured to form a second return air inlet 303, and the second return air inlet 303 is in communication with the second storage cavity 1012.

[0120] The second return air inlet 303 can include a plurality of openings arranged at intervals along the width direction of the refrigerator, forming a grating shape, which can have a larger area of the second return air inlet 303 and can also shield the structure in the evaporation chamber 301.

[0121] In some embodiments, there is a gap between the front end of the evaporator 200 and the first return air inlet 302 along the depth direction of the refrigerator, and there is a gap between the front end of the evaporator 200 and the second return air inlet 303 along the depth direction of the refrigerator, so that the air entering the first return air inlet 302 and the second return air inlet 303 can be buffered at the front end of the evaporator 200, so as to enter the evaporator 200 uniformly for heat exchange, which is beneficial to improve the heat exchange efficiency of the evaporator 200.

[0122] In combination Figure 6 and Figure 7 In some embodiments of the application, the air return direction of the first return air inlet 302 is different from the air return direction of the second return air inlet 303, which can reduce the influence of the air flow through the first return air inlet 302 and the second return air inlet 303 on the heat exchange efficiency of the evaporator 200, and can also reduce the influence of the opening and closing of one storage cavity on the other storage cavity.

[0123] For example, the air return direction of the first return air inlet 302 is toward the front side of the refrigerator, and the air return direction of the second return air inlet 303 is toward the lower side.

[0124] Exemplarily, the air return direction of the first air return port 302 is upward, and the air return direction of the second air return port 303 is downward.

[0125] In some embodiments, when the fan 600 in the evaporator module 30 is arranged upward relative to the middle cross beam 12, the first air return port 302 returns air in the front-rear direction of the refrigerator, and the second air return port 303 returns air in the height direction of the refrigerator. In this way, the space below the evaporator module 30 is relatively large, and the air return of the second air return port 303 is more smooth.

[0126] In some embodiments, when the fan 600 in the evaporator module 30 is arranged downward relative to the middle cross beam 12, the first air return port 302 returns air in the height direction of the refrigerator, and the second air return port 303 returns air in the front-rear direction of the refrigerator.

[0127] In some possible implementations of the present application, the positions of the first air return port 302 and the second air return port 303 in the depth direction of the refrigerator are staggered, so that the collision of air flows of the first air return port 302 and the second air return port 303 can be reduced to affect the air return efficiency.

[0128] In combination Figure 4 The evaporator module 30 of the embodiments of the present application can further include a first heat insulation plate 300 fixed in the shell member 100. The first heat insulation plate 300 can be clamped in the shell member 100, so that there is no need to open a hole in the shell member 100 for fixation, which is beneficial to ensuring the relative sealing of the shell member 100.

[0129] Part of the first heat insulation plate 300 is in contact with the top surface of the evaporator 200, so that the air flows after heat exchange by the evaporator 200, avoiding the air flowing without heat exchange by the evaporator 200, to ensure the heat exchange efficiency of the air, thereby helping to improve the refrigeration efficiency.

[0130] The first heat insulation plate 300 extends to the front side of the evaporator 200, so that the top surface of the evaporator 200 has a larger heat insulation area, improving the heat insulation and heat preservation performance of the chamber where the evaporator 200 is located. Moreover, the first heat insulation plate 300 extending to the front side of the evaporator 200 can also guide the air entering the evaporator 200, improving the smoothness of air flow.

[0131] In the embodiments of the present application, by arranging the first heat insulation plate 300 on the top surface of the evaporator 200, the ability of the evaporator module 30 to block external heat from entering one side of the evaporator 200 is improved, and the chamber where the evaporator 200 is located also has heat preservation performance, ensuring that the evaporator 200 maintains its low temperature, i.e., improving the heat insulation and heat preservation performance of the evaporator module 30.

[0132] Exemplarily, the first heat insulation plate 300 can include a foam plate, which is low in cost and light in weight. The first heat insulation plate 300 can include a vacuum insulation panel (VIP) to improve the heat preservation performance of the first heat insulation plate 300.

[0133] In combination Figure 4 The evaporator module 30 of the embodiment of the present application can further include a second heat insulation plate 400 fixed in the shell 100 and located below the evaporator 200. In this way, the evaporator 200 is located between the second heat insulation plate 400 and the first heat insulation plate 300.

[0134] In the embodiment of the present application, by arranging the second heat insulation plate 400 on the top surface of the evaporator 200, the ability of the evaporator module 30 to block the external heat from entering the side of the evaporator 200 is improved, and the cavity in which the evaporator 200 is located can also have heat preservation performance, so as to ensure that the evaporator 200 maintains its low temperature, i.e., the heat insulation and heat preservation performance of the evaporator module 30 is improved.

[0135] Exemplarily, the second heat insulation plate 400 can include a foam plate, which is low in cost and light in weight. The second heat insulation plate 400 can include a vacuum insulation panel (VIP) to improve the heat preservation performance of the first heat insulation plate 300.

[0136] In the embodiment of the present application, the first heat insulation plate 300 is arranged above the evaporator 200, and the second heat insulation plate 400 is arranged below the evaporator 200, so as to improve the heat insulation and heat preservation performance of the evaporation cavity 301. This can reduce the heat from the external environment entering the evaporation cavity 301, thereby reducing the working load of the compressor and facilitating the reduction of energy consumption. Moreover, the arrangement of the first heat insulation plate 300 and the second heat insulation plate 400 can also reduce the influence of the defrosting heat of the evaporator 200 on the first storage cavity 1011 and the second storage cavity 1012, and can also avoid the evaporator 200 from excessively cooling the first storage cavity 1011 and the second storage cavity 1012, thereby affecting the storage quality.

[0137] Of course, the arrangement of the first heat insulation plate 300 above the evaporator 200 and the second heat insulation plate 400 below the evaporator 200 can also improve the protection of the evaporator 200 and reduce the damage of external force to the evaporator 200.

[0138] The arrangement of the first heat insulation plate 300 and the second heat insulation plate 400 can also help to absorb and isolate noise and vibration, so that the refrigerator has a quiet running environment.

[0139] In some embodiments, the evaporator module 30 further comprises a lower cover plate 130 fixed to the top surface of the second heat insulation plate 400 and in contact with the bottom surface of the evaporator 200, such that there is no gap between the bottom surface of the evaporator 200 and the lower cover plate 130, so as to make the air pass through the evaporator 200 as much as possible to improve the heat exchange efficiency.

[0140] In addition, the lower cover plate 130 can improve the support of the evaporator 200 and protect the second heat insulation plate 400.

[0141] In the embodiments of the present application, the evaporator module 30 can further comprise a heater configured to heat the evaporator 200 for defrosting. The heater can be arranged between the lower cover plate 130 and the second heat insulation plate 400, which can reduce the resistance of the heater to the defrosting water; or the heater can be arranged above the lower cover plate 130 and located in the fin interval of the evaporator 200, which is conducive to improving the heating defrosting effect.

[0142] Continuing to refer to Figure 4 and Figure 5 In some embodiments of the present application, the evaporator module 30 comprises an air duct shell 500 located in the box body 11 and at the rear side of the shell member 100. The air duct shell 500 is fixedly connected with the shell member 100.

[0143] The air duct shell 500 is configured to form an air inlet 501 and at least part of an air duct 502. The air duct 502 is in communication with the air inlet 501 and the rear side of the evaporating chamber 301 through the air inlet 501.

[0144] The air duct shell 500 can be configured to form a complete air duct 502 to communicate the evaporating chamber 301 and the storage cavity, so as to facilitate the modular installation and disassembly of the evaporator module 30. Alternatively, part of the air duct shell 500 is configured to form part of the air duct 502, and another part of the air duct shell 500 is in communication with the box body 11 to form another part of the air duct 502, so as to reduce the space occupation of the evaporator module 30 in the depth direction of the refrigerator.

[0145] The evaporator module 30 of the embodiments of the present application can further comprise a fan 600 installed at one end of the air duct 502 facing the air inlet 501. The fan 600 is opposite to at least part of the air inlet 501 in the depth direction of the box body 11, which is conducive to reducing the air suction resistance of the fan 600 at the air inlet 501.

[0146] In combination with Figure 8The front side of the air duct shell 500 is protruded forward to form a protruding portion 540, and the air inlet 501 is formed on the protruding portion 540. The protruding portion 540 can provide sufficient installation space for the fan 600, and the air inlet 501 can also extend forward into the evaporation chamber 301, which is beneficial to improve the air suction efficiency.

[0147] With reference to the accompanying drawings Figure 8 The rear side of the shell member 100 is also configured to form a matching opening, so that the protruding portion 540 communicates with the evaporation chamber 301 through the matching opening.

[0148] It should be noted that, in Figure 8 , the shell member 100 is rotated for the purpose of showing the matching opening of the shell member 100, and the position of the shell member 100 and the air duct shell 500 is not shown.

[0149] In some embodiments, the axial direction of the fan 600 can be perpendicular to the vertical plane determined by the height direction and the width direction of the refrigerator, so that the fan 600 is opposite to at least part of the evaporation chamber 301 through the air inlet 501. In this way, the projection of the evaporator 200 in the vertical plane and the projection of the fan 600 in the vertical direction at least partially overlap, so that the air inlet 501 and the evaporation chamber 301 have a larger opposite area, which is beneficial to improve the air suction efficiency of the fan 600.

[0150] In combination Figure 9 , the air duct shell 500 extends to the first storage cavity 1011 and is configured to form a first air outlet 304, and the first air outlet 304 communicates the air duct 502 and the first storage cavity 1011.

[0151] The first air outlet 304 can be provided with a plurality of first air outlets 304, and the plurality of first air outlets 304 can be arranged along the width direction of the refrigerator and / or the height direction of the refrigerator. The air outlet area is increased, and the air outlet position is increased, which is beneficial to improve the uniformity of air supply.

[0152] In some embodiments, the air duct shell 500 extends to the second storage cavity 1012 and is configured to form a second air outlet 305, and the second air outlet 305 is located below the first air outlet 304. The second air outlet 305 communicates the air duct 502 and the second storage cavity 1012.

[0153] In some embodiments, the air duct shell 500 extends to the second storage cavity 1012 and is configured to form a second air outlet 305, and the second air outlet 305 is located below the first air outlet 304. The second air outlet 305 communicates the air duct 502 and the second storage cavity 1012.

[0154] In some embodiments of the present application, the part of the air duct shell 500 extending to the second storage cavity 1012 can also be configured to form a third air outlet 306, which is located below the second air outlet 305. The third air outlet 306 can be provided in multiple numbers, and the multiple third air outlets 306 can be arranged at intervals along the width direction of the refrigerator and / or the height direction of the refrigerator.

[0155] For example, the second air outlet 305 is arranged at intervals along the width direction of the refrigerator, and the third air outlet 306 is located between the two second air outlets 305 along the width direction of the refrigerator.

[0156] In this way, multiple air supply positions are formed in the second storage cavity 1012, which helps to improve the air supply amount; the air outlets arranged at different heights and different widths help to improve the uniformity of air supply.

[0157] The air supply direction of the second air outlet 305 can be different from that of the third air outlet 306. The second air outlet 305 can be configured to supply air to the front side, and the third air outlet 306 can be configured to supply air downward toward the front side. In this way, air can be supplied from different directions into the second storage cavity 1012, which helps to improve the uniformity of cold air distribution in the second storage cavity 1012.

[0158] In embodiments of the present application, the rear end of the evaporator 200 is spaced apart from the air duct shell 500 along the depth direction of the refrigerator. The general air suction port 501 is circular in shape to match the shape of the fan 600, facilitating air suction by the fan 600; the cross-sectional shape of the evaporator 200 is generally rectangular. By providing a spacing between the rear end of the evaporator 200 and the air duct shell 500, the air flowing through the evaporator 200 is buffered and dispersed in the spacing, so that the cold air can enter the air duct 502 through the air suction port 501 more uniformly, improving the smoothness of the cold air flow.

[0159] Through the above arrangement, under the action of the fan 600, the air in the first storage cavity 1011 enters the evaporating chamber 301 through the first air return port 302, and the air in the second storage cavity 1012 enters the evaporating chamber 301 through the second air return port 303, and exchanges heat with the evaporator 200; then enters the air duct 502 through the air suction port 501, and then returns to the first storage cavity 1011 through the first air outlet 304, and returns to the second storage cavity 1012 through the second air outlet 305, so as to circulate to reduce the temperature in the first storage cavity 1011 and the second storage cavity 1012.

[0160] In combination Figure 8 and Figure 10 In some embodiments of the present application, the rear end of the bottom wall of the outer shell 100 is configured to form a rear side plate 121. The rear end of the lower cover 120 is configured to form the rear side plate 121.

[0161] As Figure 10 shown, the lower cover 120 can include a bottom side plate 123, which is located below the evaporator 200 and is configured to form a bottom wall of the housing 100.

[0162] The bottom side plate 123 can include a bottom plate portion 1231, a first plate portion 1232 and a second plate portion 1233. The bottom plate portion 1231 is located below the evaporator 200 and the rear end of the bottom plate portion 1231 is inclined downward to facilitate the defrosting water to gather rearward. The front end of the bottom plate portion 1231 is configured to form the second return air opening 303, and the rear end of the bottom plate portion 1231 is connected with the first plate portion 1232. The rear end of the first plate portion 1232 is inclined downward and the first plate portion 1232 is located below the bottom plate portion 1231.

[0163] The second plate portion 1233 is provided with two second plate portions 1233, which are arranged side by side along the width direction of the refrigerator. Both of the second plate portions 1233 are connected with the first plate portion 1232, and the connected end of the two second plate portions 1233 is inclined downward. In this way, the inclined arrangement of the bottom plate portion 1231, the first plate portion 1232 and the second plate portion 1233 facilitates the defrosting water of the evaporator 200 to gather rearward.

[0164] The lower cover 120 can further include a left side plate 124 and a right side plate 125, which are respectively fixed to the two sides of the bottom side plate 123 along the width direction of the refrigerator to form the side walls of the evaporating chamber 301 along the width direction of the refrigerator.

[0165] The second heat insulation plate 400 is installed above the lower cover 120 in a shape-fitting manner, and the lower cover plate 130 is installed above the second heat insulation plate 400 in a shape-fitting manner.

[0166] The rear side plate 121 is connected to the rear end of the second plate portion 1233 and is located above the second plate portion 1233. The rear side plate 121 is connected with the left side plate 124 and the right side plate 125 on both sides along the width direction of the refrigerator.

[0167] In some embodiments of the present application, the rear side plate 121 and the lower cover 120 are an integral part formed integrally, which is convenient for processing and forming, and helps to improve the relative sealing of the evaporating chamber 301.

[0168] In order to drain the defrosting water of the evaporator 200, the housing 100 is further configured to form a drainage structure 122, which is connected with the connection of the two second plate portions 1233, i.e. so that the drainage structure 122 is located at the lowest position of the two second plate portions 1233, facilitating the complete drainage of the defrosting water. The drainage structure 122 penetrates through the rear side plate 121 and the tank 11 to drain the defrosting water.

[0169] In combinationFigure 7 and Figure 11 In the embodiments of the present application, the rear side plate 121 is opposite to the part of the air duct shell 500 along the depth direction of the refrigerator; and the evaporator module 30 can further include a first sealing member 700 fixed between the rear side plate 121 and the air duct shell 500.

[0170] The first sealing member 700 can be an elastic rubber pad, a silica gel pad, or the like, and can also be a sealing foam, a sealing foam pad, or the like.

[0171] The embodiments of the present application set the first sealing member 700 between the rear side plate 121 and the air duct shell 500, improve the sealing performance between the first sealing member 700 and the air duct shell 500, so that the cold air in the evaporating chamber 301 can pass through the air suction port 501 into the air duct 502 as much as possible to improve the air suction efficiency, which helps to improve the refrigeration efficiency; reduces the possibility of cold air leakage between the rear side plate 121 and the air duct shell 500, and also reduces the possibility of water seepage between the rear side plate 121 and the air duct shell 500 due to cold air leakage, thereby improving the safety and reliability of the evaporator module 30.

[0172] In addition, setting the first sealing member 700 between the rear side plate 121 and the air duct shell 500 also helps to improve the heat insulation and heat preservation performance of the rear side of the evaporating chamber 301.

[0173] In combination with Figure 11 and Figure 12 In some embodiments of the present application, the side of the rear side plate 121 facing the air duct shell 500 is configured to form a receiving groove 1213, and at least part of the first sealing member 700 is located in the receiving groove 1213.

[0174] The shape of the receiving groove 1213 is consistent with the shape of the first sealing member 700, which facilitates the assembly of the first sealing member 700.

[0175] For example, the edge of the rear side plate 121 forms a flange, and the flange and the rear side plate 121 enclose the receiving groove 1213, which is open toward the rear side. In this way, the injection molding of the rear side plate 121 is facilitated.

[0176] In the embodiments of the present application, the receiving groove 1213 is formed on the side of the rear side plate 121 facing the air duct shell 500 to accommodate at least part of the first sealing member 700, which not only reduces the installation space of the first sealing member 700 along the depth direction of the refrigerator, but also limits the position of the first sealing member 700 in the plate surface of the rear side plate 121, thereby improving the reliability of the installation position of the first sealing member 700. Moreover, the setting of the receiving groove 1213 can also indicate the installation of the first sealing member 700, which helps to improve the assembly efficiency of the first sealing member 700 and the consistency of the assembly position of the first sealing member 700.

[0177] In some embodiments, the first seal 700 is bonded with at least one of the rear side plate 121 and the air duct shell 500, not only fixing the position of the first seal 700, but also stabilizing the assembly of the first seal 700, without the need to set a fixing structure on the rear side plate 121 and the air duct shell 500, which helps to simplify the structure of the rear side plate 121 and the air duct shell 500.

[0178] In other embodiments, the air duct shell 500 is clamped with the rear side plate 121, so that the first seal 700 is clamped between the air duct shell 500 and the rear side plate 121. In this way, the fixed connection of the air duct shell 500 and the rear side plate 121 makes the first seal 700 clamped and fixed, without the need to additionally set a fixing process of the first seal 700, which is conducive to improving the assembly efficiency of the evaporator module 30.

[0179] For example, in combination with Figure 8 , the air duct shell 500 is provided with a buckle 511; in combination with Figure 12 , the rear side plate 121 is provided with a buckle opening 1212; the buckle 511 is clamped with the rear side plate 121 through the buckle opening 1212, so as to clamp the first seal 700 between the air duct shell 500 and the rear side plate 121. Among them, the first seal 700 is provided with a relief gap to avoid the clamping of the rear side plate 121 and the air duct shell 500.

[0180] Continuing to refer to Figure 12 In some embodiments of the present application, the rear side plate 121 is configured to form a first gap 1211, so that the rear side plate 121 surrounds at least part of the outside of the air inlet 501. That is, the first gap 1211 is provided on the rear side plate 121 to avoid the protruding part 540 provided on the air duct shell 500, so as to avoid the rear side plate 121 from blocking the air inlet 501 and affecting the air suction efficiency.

[0181] Again in combination with Figure 8 In the embodiments of the present application, the upper cover 110 is configured to form a third gap 111, and the third gap 111 and the first gap 1211 form a matching gap, so that the air inlet 501 of the air duct shell 500 communicates with the evaporation chamber 301 through the matching gap. Of course, the first heat insulation plate 300 is provided with a gap to avoid blocking the air inlet 501 of the air duct shell 500.

[0182] As Figure 12 shown, the first seal 700 is configured to form a second gap 701, so that the first seal 700 surrounds at least part of the outside of the air inlet 501. The second gap 701 penetrates the thickness direction of the first seal 700, and the second gap 701 is upwardly open.

[0183] The second gap 701 is formed in the first sealing member 700, which not only avoids the air suction port 501, but also surrounds at least part of the outer side of the air suction port 501, improves the sealing performance around the air suction port 501, and makes the cold air in the evaporation chamber 301 pass through the air suction port 501 into the air duct 502 as much as possible, and reduces the leakage between the rear side plate 121 and the air duct shell 500.

[0184] With reference to the foregoing Figure 12 , the drain structure 122 formed by the shell member 100 is located below the first gap 1211; the drain structure 122 is configured to extend to the outside of the tank 11.

[0185] The first sealing member 700 is provided with a through hole 702 to avoid the drain structure 122.

[0186] The air duct shell 500 and the tank 11 can also be provided with a through hole to enable the drain structure 122 to extend to the outside of the tank 11.

[0187] In the embodiments of the present application, the shell member 100 forms the drain structure 122 below the first gap 1211 to drain the defrosting water of the evaporator 200, and the through hole 702 is arranged on the first sealing member 700 to avoid the drain structure 122, so that the first sealing member 700 is arranged between the rear side plate 121 and the air duct shell 500 on both sides of the drain structure 122, reducing the possibility of water seepage between the drain structure 122, the rear side plate 121 and the air duct shell 500, and improving the safety and reliability of the evaporator module 30.

[0188] As shown in Figure 12 and Figure 13 , in some embodiments of the present application, the first sealing member 700 includes two sealing portions 710, which are arranged at intervals along the width direction of the tank 11, and the interval between the two sealing portions 710 forms the through hole 702.

[0189] The embodiments of the present application form the first sealing member 700 by arranging two sealing portions 710, the area of a single sealing portion 710 is small, which facilitates the assembly of the sealing portion 710 and the processing and molding of the sealing portion 710. Moreover, the two sealing portions 710 are the same, and there is no need to design an error-proof structure, which facilitates improving the assembly efficiency of the sealing portion 710.

[0190] In combination with Figure 5 and Figure 14In some embodiments of the present application, the air duct shell 500 comprises a first air duct plate 510, the first air duct plate 510 faces the evaporator 200, the first air duct plate 510 is configured to form the air suction port 501, and a first sealing member 700 is arranged between the first air duct plate 510 and the back plate 121. In addition, the first air duct plate 510 is also configured to form the second air supply port 305 and the third air supply port 306.

[0191] The air duct shell 500 can further comprise a second air duct plate 520, the second air duct plate 520 is fixed to a side of the first air duct plate 510 away from the evaporator 200, so that the second air duct plate 520 is located at the back side of the first air duct plate 510. The second air duct plate 520 is configured to form the first air duct 5021 together with the first air duct plate 510.

[0192] The air duct 502 comprises the first air duct 5021, and the fan 600 is installed in the first air duct 5021. The second air supply port 305 and the third air supply port 306 communicate with the first air duct 5021.

[0193] In the embodiments of the present application, the air duct shell 500 is configured to form the first air duct 5021 by arranging the first air duct plate 510 and the second air duct plate 520, and the fan 600 is installed in the first air duct 5021, which helps to fix and install the fan 600. The first air duct plate 510 is configured to form the air suction port 501, and the first sealing member 700 is arranged between the first air duct plate 510 and the back plate 121, which improves the sealing between the first air duct plate 510 and the back plate 121, so that the cold air in the evaporation chamber 301 can enter the first air duct 5021 through the air suction port 501 as much as possible, and the possibility of cold air leakage between the first air duct plate 510 and the back plate 121 is reduced.
