[0068] In the description of the present embodiment, reference to terms such as "embodiment" or "implementation method" indicates that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0069] The following combination Figures 1 to 19 The refrigerator of this embodiment is described in detail. Figure 14 and Figure 15 The schematic diagram of the cooling and heat exchange components is hidden. Figure 17 、 Figure 18 and Figure 19 The blank arrows in the figure indicate the flow path and direction of the refrigeration airflow.

[0070] In the prior art, air-cooled refrigerators are equipped with a freezer drawer within the freezer compartment. This freezer drawer is used to freeze food by directing a refrigerated airflow around the drawer. This prevents the refrigerated airflow from directly contacting the food inside the drawer, effectively preventing moisture loss. However, this method of freezing slows the freezing process and cannot meet the storage needs of some foods that require rapid freezing (such as aquatic products). Consequently, it fails to meet user needs, resulting in a reduced user experience.

[0071] Reference Figure 1 、 Figure 2 and Figure 5 In this embodiment, the refrigerator includes a cabinet 100 , a freezing drawer 200 and a circulation fan 300 .

[0072] A freezing compartment 110 is provided in the housing 100 .

[0073] The freezer drawer 200 is arranged in the freezer compartment 110. A drawer cavity 210 is provided in the freezer drawer 200. An air-cooling duct 120 is provided between the top of the freezer drawer 200 and the top wall of the freezer compartment 110. The top of the drawer cavity 210 has an upward-opening access port 220.

[0074] The circulation fan 300 is arranged in the air-cooling supply duct 120, and the fan outlet of the circulation fan 300 faces the drawer cavity 210. The circulation fan 300 is used to promote the refrigerated air flow in the air-cooling supply duct 120 to flow into the drawer cavity 210 when it is in the started state.

[0075] Since the refrigerator of this embodiment is provided with a circulation fan 300 in the air-cooled cooling duct 120, and the fan outlet of the circulation fan 300 is arranged toward the drawer cavity 210 of the freezing drawer 200, the circulation fan 300 can promote the refrigerated airflow in the air-cooled cooling duct 120 to flow into the drawer cavity 210 when it is started, so that the food in the drawer cavity 210 can be quickly frozen.

[0076] Therefore, this embodiment enables the air-cooled refrigerator to quickly freeze food, meets the user's demand for quickly freezing food, and improves the user experience.

[0077] Reference Figure 2 and Figure 3 In this embodiment, a cooling air outlet 130 is provided at the rear of the freezing compartment 110 and the rear end of the cooling air duct 120 . The cooling air outlet 130 is used to provide a refrigerated air flow into the cooling air duct 120 .

[0078] Reference Figure 2 and Figure 3In this embodiment, the cooling air inlet 130 is arranged forward, and the cooling air inlet 130 is used to provide refrigerated air flow forward into the cooling air duct 120 when the circulation fan 300 is in the started and stopped states.

[0079] It can be understood that since the refrigerated air flow flows forward and the circulation fan 300 is located in front of the cooling air outlet 130, the smoothness of the air path between the cooling air outlet 130 and the circulation fan 300 can be guaranteed, so that the air-cooled refrigerator can further freeze the food quickly, further ensuring the user experience.

[0080] Furthermore, by setting the cooling air outlet 130 forward and the cooling air outlet 130 higher than the freezing drawer 200, when the circulating fan 300 is in a stopped state, the refrigerated air flow will flow at the top of the freezing drawer 200 to freeze the food in the drawer cavity 210, and a small amount or even no refrigerated air flow will flow into the drawer cavity 210, thereby better ensuring that the moisture of the food is not lost, thereby achieving moisturizing freezing of the air-cooled refrigerator.

[0081] Therefore, the refrigerator of this embodiment can realize the switching between the quick freezing function and the moisturizing freezing function on the same freezing drawer 200 by starting or stopping the circulating fan 300, so that the same freezing drawer 200 can meet the user's demand for the food to be quickly frozen, and can also take into account the user's demand for the food to be frozen without losing moisture, which greatly improves the user experience.

[0082] Reference Figure 2 and Figure 3 In this embodiment, the circulation fan 300 is provided corresponding to the cooling air outlet 130 .

[0083] It can be understood that by arranging the circulating fan 300 in correspondence with the cooling air outlet 130, the flow rate of the refrigerated air flow entering the drawer cavity 210 can be guaranteed, while the smoothness of the air path between the cooling air outlet 130 and the circulating fan 300 can be guaranteed, so that the air-cooled refrigerator can further freeze the food quickly, further ensuring the user experience.

[0084] Reference Figure 2 and Figure 3 In this embodiment, the circulation fan 300 is arranged corresponding to the middle of the bottom surface of the drawer cavity 210.

[0085] It can be understood that by setting the circulating fan 300 at a position corresponding to the middle of the bottom surface of the drawer cavity 210, the refrigerated air flow entering the drawer cavity 210 can flow through various areas of the drawer cavity 210 as much as possible, ensuring the consistency of the freezing degree of the food in the drawer cavity 210, improving the freezing quality of the food in the refrigerator, and improving the user experience.

[0086] Furthermore, in the prior art, to completely prevent the flow of refrigerated air into the drawer cavity 210 and to ensure that the refrigerated airflow only flows around the freezer drawer 200, thereby further preventing moisture loss in the food and greatly ensuring the quality of the food, the drawer cavity 210 of the refrigerator is configured to be relatively sealed relative to the refrigerated airflow. For example, a top cover 400 is provided at the access opening 220 of the freezer drawer 200; in another example, the freezer drawer 200 is configured as a cylindrical structure with a front-opening access opening 220, and the access opening 220 of the freezer drawer 200 will only open when the door of the freezer compartment 110 is opened. However, the relatively sealed setting of the drawer cavity 210 further delays the freezing process of the food, further reducing the user experience.

[0087] Reference Figure 2 and Figure 3 In this embodiment, the refrigerator includes a top cover 400 .

[0088] The top cover 400 is provided at the taking-out port 220 and is located between the drawer cavity 210 and the air-cooled cooling duct 120 . The top cover 400 is used to limit the flow of refrigerated air into the drawer cavity 210 when the circulating fan 300 is stopped.

[0089] A circulating air inlet 410 is provided on the top cover 400, and a moisturizing air outlet 500 connected to the drawer cavity 210 is provided on the top cover 400 and / or the freezer drawer 200. The circulating fan 300 is provided at the circulating air inlet 410. The circulating fan 300 is used to promote the refrigerated air flow in the air-cooled cooling duct 120 to flow into the drawer cavity 210 through the circulating air inlet 410 when the circulating fan 300 is started, and to discharge the refrigerated air flow out of the drawer cavity 210 through the moisturizing air outlet 500 when the circulating fan 300 is started.

[0090] It is understandable that when a top cover 400 is provided at the drawer access opening 220, a circulating air inlet 410 can be provided on the top cover 400, and a moisturizing air outlet 500 can be provided on the freezing drawer 200 and / or the top cover 400, and the circulating fan 300 can be provided at the circulating air inlet 410. When the circulating fan 300 is in the activated state, the refrigerated air flow in the air-cooling supply duct 120 can be continuously flowed into the drawer cavity 210, so that the food in the drawer cavity 210 can be quickly frozen, meeting the user's demand for quick freezing of food and ensuring the user's usage experience.

[0091] Moreover, when the circulation fan 300 is not working, the refrigerated airflow in the air-cooled cooling duct 120 will not be sucked into the drawer cavity 210 by the circulation fan 300, and the top cover 400 can well limit the flow of the refrigerated airflow into the drawer cavity 210, so that the refrigerator can well ensure that the moisture of the food is not lost when freezing the food, that is, to achieve moisturizing freezing of the air-cooled refrigerator.

[0092] Therefore, the refrigerator of this embodiment can achieve rapid freezing of food, and by starting or stopping the circulating fan 300, the quick freezing function or the moisturizing freezing function can be switched on the same freezing drawer 200, so that the same freezing drawer 200 can meet the user's demand for food to be quickly frozen, and well meet the user's demand for food to be frozen without losing moisture, thereby greatly improving the user's experience.

[0093] Reference Figure 2 and Figure 4 In this embodiment, the circulation fan 300 includes a fan bracket 310 , a driving motor 320 and a circulation fan 330 .

[0094] The fan bracket 310 is disposed at the circulating air inlet 410 . The fan bracket 310 includes a fixing portion 311 located in the middle. The fixing portion 311 is located in the drawer cavity 210 .

[0095] The driving motor 320 is disposed on the fixing portion 311 .

[0096] The circulation fan 330 is connected to the driving shaft of the driving motor 320 .

[0097] It can be understood that by arranging the fixing portion 311 of the fan bracket 310 for fixing the circulation fan 330 and the drive motor 320 on the inner side of the drawer cavity 210, the flow of the refrigeration airflow in the air-cooled cooling duct 120 will not be affected, thereby ensuring the smoothness of the flow of the refrigeration airflow around (top) of the freezer drawer 200.

[0098] Furthermore, by configuring the fan bracket 310 , the drive motor 320 and the circulation fan 330 , the construction of the circulation fan 330 is realized, thereby ensuring the user experience.

[0099] Reference Figure 2 In this embodiment, the height H of the freezer drawer 200 corresponding to the position of the circulation fan 300 in the front-to-back direction is higher than the height L of the rear end of the freezer drawer 200; and the height of the top cover 400 corresponding to the position of the circulation fan 300 in the front-to-back direction is higher than the height of the rear end of the top cover 400.

[0100] It can be understood that the top of the freezer drawer 200 and the top cover 400 as a whole is tilted downward from front to back, thereby ensuring the smooth forward flow of the refrigerated airflow flowing out of the cooling air outlet 130, and ensuring the smoothness of the air path between the cooling air outlet 130 and the circulating fan 300, so as to further enable the air-cooled refrigerator to quickly freeze the food and further ensure the user experience.

[0101] Reference Figure 3 In this embodiment, the moisturizing air outlet 500 is provided on at least one of the top cover 400, the front end of the freezer drawer 200, the rear end of the freezer drawer 200, the left end of the freezer drawer 200 and the right end of the freezer drawer 200.

[0102] It is understood that the specific location of the moisturizing air outlet 500 can be set at any position of the moisturizing air outlet 500 according to the return air requirements of the refrigerated airflow, or it can be set on the top cover 400, as long as the refrigerated airflow in the drawer cavity 210 can be discharged. Furthermore, in order to ensure that the refrigerated airflow can be smoothly returned to the evaporator 141, the moisturizing air outlet 500 can be opened adjacent to the refrigerator return air duct 150.

[0103] Reference Figure 3 In this embodiment, the total air outlet area of ​​the moisturizing air outlet portion 500 is greater than the air inlet area of ​​the circulating air inlet 410 .

[0104] It can be understood that the total air outlet area of ​​the moisturizing air outlet portion 500 is larger than the air inlet area of ​​the circulating air inlet 410. Therefore, when the circulating fan 300 is started, the refrigerated air flow in the drawer cavity 210 after heat exchange with the food can be smoothly discharged to the outside of the drawer cavity 210, and the refrigerated air flow in the air-cooled cooling duct 120 can be smoothly sucked into the drawer cavity 210 by the circulating fan 300, so as to effectively ensure the quick-freezing effect of the refrigerator on the food.

[0105] Moreover, when the circulating fan 300 stops, the refrigerated air flow in the air-cooled cooling duct 120 can flow into the drawer cavity 210 through the circulating air inlet 410 as little as possible, or even not flow into the drawer cavity 210 through the circulating air inlet 410, so as to ensure the moisture content of the frozen food, that is, to ensure the moisturizing effect of the refrigerator on the food.

[0106] Reference Figure 3 In this embodiment, the ratio of the total air outlet area of ​​the moisturizing air outlet portion 500 to the air inlet area of ​​the circulating air inlet 410 is in a range of 0.4 to 0.6.

[0107] It is understood that the ratio of the total air outlet area of ​​the moisturizing air outlet portion 500 to the air inlet area of ​​the circulating air inlet 410 can be 0.4, 0.45, 0.5, 0.55, 0.6, etc., to further ensure the quick freezing effect of the food when the circulating fan 300 of the refrigerator is started, and the moisture content of the frozen food when the circulating fan 300 is stopped.

[0108] Reference Figure 3 In this embodiment, the moisturizing air outlet portion 500 includes a cover air outlet 510 .

[0109] The cover air outlet 510 is provided on the top cover 400. The refrigerated airflow after heat exchange with the food in the drawer cavity 210 can be returned to the air cooling duct 120 through the cover air outlet 510 and discharged from the drawer cavity 210.

[0110] Furthermore, the number of the cover air outlet 510 can be multiple.

[0111] Reference Figure 3 In this embodiment, the multiple cover air outlets 510 include a first cover vent 511 arranged adjacent to the left end of the top cover 400, a second cover vent 512 arranged adjacent to the right end of the top cover 400, and a third cover vent 513 arranged adjacent to the rear end of the top cover 400; and, the first cover vent 511 is located on the left side of the cooling air outlet 130, and the second cover vent 512 is located on the right side of the cooling air outlet 130.

[0112] It is understood that some of the cover air outlets 510 (the first cover vent 511 and the second cover vent 512) are arranged adjacent to the left and right ends of the top cover 400 on the left and right sides of the cooling air outlet 130, and thus some of the cover air outlets 510 are not distributed on the main flow path of the refrigerated air in the cooling air duct 120. This effectively prevents the refrigerated air in the cooling air duct 120 from entering the drawer cavity 210 through the cover air outlet 510, ensuring that the refrigerator can normally perform rapid freezing and moisturizing freezing of food.

[0113] At the same time, another part of the cover air outlet 510 (the third cover vent 513) is arranged adjacent to the rear end of the top cover 400, and since the height of the cooling air outlet 130 is higher than the rear end of the top cover 400, the refrigerated air flow flowing forward from the cooling air outlet 130 will not flow into the drawer cavity 210 through the third cover vent 513, ensuring that the refrigerator can quickly freeze the food and moisturize the food normally.

[0114] Reference Figure 3 In this embodiment, the moisturizing air outlet portion 500 includes a circulating air outlet 520 .

[0115] The circulating air outlet 520 is opened at the front end of the freezing drawer 200. Then, the refrigerated air flow after heat exchange with the food in the drawer cavity 210 can be discharged from the drawer cavity 210 to the front of the freezing drawer 200 through the circulating air outlet 520.

[0116] Reference Figure 3 In this embodiment, the number of the circulating air outlets 520 can be set to multiple, and the multiple circulating air outlets 520 are arranged in the left-right direction.

[0117] Reference Figure 2 、 Figure 17 、 Figure 18 or Figure 19 In this embodiment, an evaporation chamber 140 for placing an evaporator 141 of the refrigerator and a return air duct 150 connected to the evaporation chamber 140 are provided in the cabinet 100. The moisturizing air outlet 500 is connected to the return air duct 150.

[0118] It can be understood that, through the setting of the return air duct 150, the refrigerated air flow flowing out of the moisturizing air outlet 500 can flow back to the evaporation compartment 140 to exchange heat with the evaporator 141, and the refrigerated air flow after heat exchange with the evaporator 141 continues to be transported to the cooling air outlet 130 (and / or the cooling air supply outlet 170), realizing the circulation of the refrigerated air flow and ensuring the operation of the refrigerator.

[0119] Reference Figure 2 、 Figure 17 、 Figure 18 or Figure 19 In this embodiment, the return air duct 150 includes a return air section 151 located in front of the freezer drawer 200. The moisturizing air outlet 500 is connected to the return air section 151, allowing the refrigerated airflow that flows out of the drawer cavity 210 through the moisturizing air outlet 500 to flow back into the evaporation compartment 140. After exchanging heat with the evaporator 141, the refrigerated airflow is further transported to the cooling air outlet 130 (and / or the cooling air supply outlet 170), achieving a circulation of the refrigerated airflow and ensuring the operation of the refrigerator.

[0120] Reference Figure 1 、 Figure 2 and Figure 16 In this embodiment, an access opening 160 is opened in front of the freezer compartment 110, and the refrigerator includes a drawer door 600, which is arranged at the access opening 160 and connected to the front of the freezer drawer 200, and the return air section 151 is located between the drawer door 600 and the freezer drawer 200.

[0121] Reference Figure 2 、 Figure 3 、 Figure 17 、 Figure 18 and Figure 19In this embodiment, the circulating air outlet 520 is connected to the return air section 151 to allow the refrigerated airflow flowing out of the drawer cavity 210 through the circulating air outlet 520 to flow back into the evaporation compartment 140 .

[0122] It can be understood that the specific form of the moisturizing air outlet 500 being connected to the return air duct 150 can be that the circulating air outlet 520 located at the front end of the freezing drawer 200 is connected to the return air section 151, so as to realize the refrigerated air flow flowing out of the drawer cavity 210 through the circulating air outlet 520 and returning to the evaporation compartment 140.

[0123] Reference Figure 2 、 Figure 3 、 Figure 17 、 Figure 18 and Figure 19 In this embodiment, the cover air outlet 510 is connected to the air-cooling supply duct 120, and the front end of the air-cooling supply duct 120 is connected to the return air section 151, so as to allow the refrigerated air flow flowing out of the drawer cavity 210 through the cover air outlet 510 and the refrigerated air flow in the air-cooling supply duct 120 to flow back into the evaporation compartment 140.

[0124] It can be understood that the specific form of the moisturizing air outlet 500 being connected to the return air duct 150 can be that the cover air outlet 510 is connected to the air-cooling supply air duct 120, and the front end of the air-cooling supply air duct 120 is connected to the return air section 151, so as to realize that the refrigerated air flow flowing out of the drawer cavity 210 through the circulation air outlet 520 is returned to the evaporation compartment 140 together with the refrigerated air flow in the air-cooling supply air duct 120.

[0125] Reference Figure 3 In this embodiment, the total air outlet area of ​​the plurality of circulation air outlets 520 is the same as the total air outlet area of ​​the plurality of cover air outlets 510 .

[0126] It is understandable that the moisturizing air outlet portion 500 may include multiple cover air outlets 510 and multiple circulation air outlets 520 at the same time, and the total air outlet area of ​​the multiple circulation air outlets 520 is the same as the total air outlet area of ​​the multiple cover air outlets 510. Therefore, the amount of refrigerated air flowing out of the drawer cavity 210 through the cover air outlet 510 and the amount of refrigerated air flowing out of the drawer cavity 210 through the circulation air outlet 520 are the same, avoiding the difference in the flow rate of the refrigerated air flowing out of the drawer cavity 210 through the cover air outlet 510 and the amount of refrigerated air flowing out of the drawer cavity 210 through the circulation air outlet 520, which affects the stability of the flow of the refrigerated air in the entire circulation air path (the refrigerated air flows out of the evaporation compartment 140, flows through the cooling air outlet 130, the cooling air duct 120, the return air duct 150, and finally flows back to the evaporation compartment 140), thereby ensuring the normal operation of the refrigerator.

[0127] Reference Figure 2 、 Figure 5In this embodiment, a cold air duct 230 is provided at the bottom of the freezer drawer 200. The cold air duct 230 is located below the drawer cavity 210. The freezer drawer 200 includes a cold air conducting member 240 located between the drawer cavity 210 and the cold air duct 230. The cold air conducting member 240 is used to cool the food in the drawer cavity 210 by exchanging heat with the refrigerated air flow in the cold air duct 230.

[0128] In the refrigerator of this embodiment, since a cooling member 240 is provided at the bottom of the drawer cavity 210, when food is placed in the drawer cavity 210, it can be placed directly on the cooling member 240. Then, the cooling member 240 can directly contact the food, thereby promoting rapid freezing of the food in the drawer cavity 210. Therefore, this embodiment enables the air-cooled refrigerator to quickly freeze food, meeting the user's demand for quickly freezing food and improving the user experience.

[0129] Furthermore, the refrigerator of this embodiment, by disposing a circulating fan 300 at the top of the drawer cavity 210 and a cooling member 240 at the bottom of the drawer cavity 210, can further reduce the time it takes for food to be frozen. Therefore, the refrigerator of this embodiment can further meet the user's need for rapid freezing of food, further improving the user experience.

[0130] In addition, the material of the cooling member 240 can be metal materials such as aluminum, copper, and cast iron.

[0131] Reference Figure 2 、 Figure 5 In this embodiment, the circulating fan 300 is also used to force the refrigerated air flow entering the drawer cavity 210 to flow through the upper surface of the cooling member 240 when in the started state.

[0132] In this embodiment of the refrigerator, the circulating fan 300, when activated, can also force the refrigerated airflow to flow over the upper surface of the cooling element 240, thereby evenly distributing the cooling capacity on the cooling element 240. Furthermore, the refrigerated airflow entering the drawer cavity 210 can also exchange heat with the cooling element 240, maintaining consistency between the refrigerated airflow and the cooling capacity on the cooling element 240. Therefore, this embodiment can further ensure the consistency of the freezing degree of the food in the drawer cavity 210, improve the freezing quality of the food, and enhance the user experience.

[0133] In this embodiment, the moisturizing air outlet 500 connected to the drawer cavity 210 is arranged around the circulating air inlet 410, and the moisturizing air outlet 500 is arranged at the end of the adjacent freezing drawer 200, and the circulating fan 300 is used to promote the refrigerated air flow flowing through the upper surface of the cooling member 240 to flow out of the drawer cavity 210 through the moisturizing air outlet 500.

[0134] It can be understood that by arranging the moisturizing air outlet 500 around the circulating air inlet 410, and setting the moisturizing air outlet 500 adjacent to the end of the freezing drawer 200, the refrigerated air flow flowing into the drawer cavity 210 through the moisturizing air outlet 500 can flow through as much area as possible on the upper surface of the cooling member 240, so as to ensure the uniform cooling effect on the cooling member 240, thereby further improving the user experience.

[0135] In this embodiment, the first cover vent 511 is located on the left side of the circulating air inlet 410 , the second cover vent 512 is located on the right side of the circulating air inlet 410 , and the third cover vent 513 is located at the rear side of the circulating air inlet 410 .

[0136] It is understandable that the moisturizing air outlet 500 is arranged around the circulating air inlet 410. Specifically, the first cover vent 511 is located on the left side of the circulating air inlet 410, the second cover vent 512 is located on the right side of the circulating air inlet 410, the third cover vent 513 is located on the rear side of the circulating air inlet 410, and the circulating air outlet 520 is opened on the front side of the circulating air inlet 410 (the front end of the freezing drawer 200). And because the circulating fan 300 is arranged in the middle of the bottom surface of the drawer cavity 210. Then, when the refrigerated air flow flowing through the upper surface of the cooling member can flow through more space in the drawer cavity 210 as much as possible, so as to ensure the consistency of the cooling amount in various places in the drawer cavity 210, in the drawer cavity 210 and on the cooling member 240 as much as possible, so as to further enhance the user experience.

[0137] Furthermore, in the embodiment described above where the cooling element 240 for cooling food is disposed at the bottom of the drawer cavity 210, factors such as the flow rate, flow rate, and contact area of ​​the refrigerated airflow affect the heat exchange between the cooling element 240 and the refrigerated airflow. Consequently, it is difficult to guarantee the amount of cold air transferred to the cooling element 240 by the refrigerated airflow. Consequently, it is difficult to guarantee the quick-freezing effect of the food by disposing the cooling element 240 at the bottom of the drawer cavity 210, thereby reducing the user experience.

[0138] Reference Figure 2 、 Figure 6 In this embodiment, the refrigerator further includes a heat exchange component 700 .

[0139] The heat exchanger 700 is connected to the bottom of the cooling element 240 and extends in the cooling air duct 230 in the vertical direction. The heat exchanger 700 is used to exchange heat with the cooling element 240 and the refrigeration air flow.

[0140] The refrigerator of this embodiment connects the heat exchange member 700 below the cooling member 240. The heat exchange member 700 is extended in the up and down directions within the cooling air duct 230. The heat exchange member 700 increases the heat exchange area between the cooling member 240 and the refrigerated air flow to ensure the amount of cold air exchanged to the cooling member 240 by the refrigerated air flow, thereby ensuring the quick freezing effect of the refrigerator on the food and improving the user experience.

[0141] In addition, the heat exchange element 700 may be made of metal materials such as aluminum, copper, and cast iron.

[0142] Reference Figure 2 、 Figure 5 and Figure 7 In this embodiment, the height K of the heat exchange element 700 extending in the vertical direction is greater than or equal to 5 mm, which can effectively ensure the heat exchange area of ​​the heat exchange element 700, the cooling element 240 and the refrigerated airflow, so as to further ensure the amount of cold air exchanged to the cooling element 240 by the refrigerated airflow, ensure the quick freezing effect of the refrigerator on the food, and improve the user experience.

[0143] Reference Figure 2 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, the heat exchange element 700 includes heat exchange fins 710 .

[0144] The heat exchange fins 710 are disposed below the cooling member 240 . The heat exchange fins 710 are arranged in the cooling air supply and conduction duct 230 along the up-down direction, and the heat exchange fins 710 extend in the front-to-back direction.

[0145] It is understandable that the heat exchange element 700 may be a heat exchange fin 710 to increase the heat exchange area between the cooling element 240 and the refrigeration airflow.

[0146] Furthermore, specifically, the height K of the heat exchange fins 710 may be greater than or equal to 5 mm to ensure the quick freezing effect of the refrigerator on food.

[0147] Reference Figure 8 In this embodiment, the thickness M of the heat exchange fin 710 is greater than or equal to 0.1 mm to ensure the speed of heat exchange to the cooling member 240, to further ensure the cooling amount of the refrigerated airflow exchanged to the cooling member 240, to ensure the quick freezing effect of the refrigerator on the food, and to improve the user experience.

[0148] In a modified embodiment, the heat exchange element 700 includes a needle-shaped or columnar heat exchange column arranged below the cooling element 240, or a raised structure arranged below the cooling element 240 to increase the heat exchange area between the cooling element 240 and the refrigerated airflow.

[0149] Reference Figure 2 and Figure 16 In this embodiment, a cold air supply port 170 is provided at the rear of the freezer compartment 110 and at the rear end of the cold air supply duct 230. The cold air supply port 170 is used to provide refrigerated airflow into the cold air supply duct 230. The cold air supply port 170 extends in the left and right directions to ensure a large air flow, thereby ensuring the refrigerator's freezing performance and quick freezing effect.

[0150] Reference Figure 2 、 Figure 3 、 Figure 17 、 Figure 18 and Figure 19 In this embodiment, the refrigerator includes an air duct plate 800, which is arranged at the rear of the freezer compartment 110. An air supply duct 810 is formed between the air duct plate 800 and the rear wall of the freezer compartment 110. The cold air supply port 170 and the cold air supply port 130 are opened on the air duct plate 800, and the cold air supply port 170 and the cold air supply port 130 are connected to the air supply duct 810. The bottom of the air supply duct 810 is connected to the evaporation compartment 140, and the refrigerated air flow after heat exchange with the evaporator 141 flows out of the evaporation compartment 140 and flows to the cold air supply port 170 and the cold air supply port 130 through the air supply duct 810.

[0151] Reference Figure 2 、 Figure 6 and Figure 16 In this embodiment, the number of the heat exchange fins 710 is set to be multiple, the multiple heat exchange fins 710 are arranged in the left and right directions, and the multiple heat exchange fins 710 are set corresponding to the cooling air supply port 170.

[0152] It can be understood that by setting the number of heat exchange fins 710 to multiple, the heat exchange area between the cooling element 240 and the refrigerated airflow can be further increased, so as to further ensure the amount of cold air exchanged to the cooling element 240, further ensure the quick freezing effect of the refrigerator on the food, and improve the user experience.

[0153] Furthermore, it should be understood that multiple heat exchange fins 710 are arranged corresponding to the cooling air supply port 170 so that the multiple heat exchange fins 710 can all be exposed to the refrigerated airflow and exchange the cold energy of the refrigerated airflow to the heat conductive part, further ensuring the cold energy of the refrigerated airflow exchanged to the cooling conductive part 240.

[0154] Reference Figure 8 In this embodiment, the gap N between the heat exchange fins 710 is greater than or equal to 5 mm to ensure the speed of the refrigerated airflow flowing through the heat exchange fins 710, to further ensure the amount of cold air exchanged to the cooling element 240 by the refrigerated airflow, to ensure the quick freezing effect of the refrigerator on the food, and to improve the user experience.

[0155] Reference Figure 8 In this embodiment, the height K of the heat exchange fins 710 can be set to 10 mm, the gap N between any two heat exchange fins 710 is 10 mm, and the thickness M of the heat exchange fins 710 can be 1 mm.

[0156] It can be understood that the height of the heat exchange fins 710, the gap between any two heat exchange fins 710 and the thickness of the heat exchange fins 710 can be set according to the size of the cold supply air duct 230 and the flow rate or flow rate of the refrigerated air flow, so as to effectively ensure the cold amount exchanged by the refrigerated air flow to the cold guide part 240, and ensure the quick freezing effect of the refrigerator on the rapid freezing of food.

[0157] Specifically, the heat exchange fins 710 can be set to 10 mm to avoid a reduction in the heat exchange area between the heat exchange fins 710 and the refrigerated airflow due to the heat exchange fins 710 being too short in the vertical direction, and a reduction in the speed of heat exchange from the heat exchange fins 710 to the cold guide 240 due to the heat exchange fins 710 being too long in the vertical direction. The thickness of the heat exchange fins 710 can also be set to 1 mm to avoid a reduction in the speed of heat exchange from the heat exchange fins 710 to the cold guide 240 due to the heat exchange fins 710 being too thin, and an increase in the weight of the heat exchange element 700 due to the heat exchange fins 710 being too thick, thereby further increasing the weight of the freezer drawer 200. The gap between any two heat exchange fins 710 can be set to 10 mm to avoid slowing down the speed of the refrigeration airflow flowing through the heat exchange fins 710 due to the gap between the heat exchange fins 710 being too small, and reducing the heat exchange efficiency between the refrigeration airflow and the heat exchange fins 710 due to the gap between the heat exchange fins 710 being too large.

[0158] In this embodiment, the ratio of the height K to the thickness M of the heat exchange fin 710 may be in the range of 100-5. For example, the ratio of the height to the thickness of the heat exchange fin 710 may be in the range of 50. Specifically, the height of the heat exchange fin 710 may be 5 mm, and the thickness of the heat exchange fin 710 may be 0.1 mm; or, the height of the heat exchange fin 710 may be 50 mm, and the thickness of the heat exchange fin 710 may be 1 mm.

[0159] It is understandable that by limiting the ratio range of the height to thickness of the heat exchange fins 710 , that is, the ratio range of the height to thickness of the heat exchange fins 710 is 100-5, the heat exchange performance of the heat exchange fins 710 can be well guaranteed.

[0160] Reference Figure 8 In this embodiment, the heat exchange element 700 further includes an enhanced heat exchange plate 720 .

[0161] The enhanced heat exchange plate 720 is connected to the lower side of the heat exchange fin 710 . The enhanced heat exchange plate 720 is arranged in the left-right direction and extends in the front-back direction of the enhanced heat exchange plate 720 .

[0162] It can be understood that by enhancing the setting of the heat exchange plate 720, the heat exchange area between the cooling element 240 and the refrigerated airflow can be further increased to further ensure the amount of cold air exchanged to the cooling element 240, further ensure the quick freezing effect of the refrigerator on the food, and improve the user experience.

[0163] At the same time, the arrangement of the enhanced heat exchange plate 720 can improve the overall structural strength, horizontal stability and pressure bearing capacity of the heat exchange element 700 .

[0164] Reference Figure 5 、 Figure 6 and Figure 7 In this embodiment, the cooling member 240 includes a cooling plate 241 .

[0165] The cold conduction plate 241 is arranged between the drawer cavity 210 and the cold conduction and cooling air duct 230. The heat exchange component 700 is connected below the cold conduction plate 241. The cold conduction plate 241 is used to exchange heat with the heat exchange component 700 and the refrigeration airflow.

[0166] It can be understood that the cold conduction member 240 can be a plate-shaped cold conduction plate 241 arranged at the bottom of the drawer cavity 210 to achieve heat exchange with the refrigerated airflow and the heat exchange member 700, and exchange the exchanged cold energy to the food in contact with it to achieve cooling of the food.

[0167] Furthermore, in embodiments where a cooling element 240 for cooling food is disposed at the bottom of the drawer cavity 210, factors such as the flow rate, flow velocity, and heat exchange area of ​​the refrigerated airflow flowing through various locations below the cooling element 240 will affect the distribution of cooling capacity across the cooling element 240. Consequently, it is difficult to ensure uniformity of cooling capacity across the cooling element 240, which can lead to inconsistent freezing of food within the drawer cavity 210, further reducing the freezing quality of the food and diminishing the user experience.

[0168] Reference Figure 8 In this embodiment, a cooling channel 2411 is extendedly provided in the cooling plate 241 , and the cooling channel 2411 is filled with cooling liquid 2412 to evenly distribute the cooling capacity on the cooling plate 241 .

[0169] In the refrigerator of this embodiment, due to the provision of the cold conduction channel 2411 and the cold conduction liquid 2412, when the cold energy of the refrigerated airflow is transferred to the cold conduction plate 241 and a portion of the cold conduction liquid 2412, the portion of the cold conduction liquid 2412 undergoes a phase change and flows toward the location of the remaining cold conduction liquid 2412, while simultaneously transferring the cold energy to the remaining cold conduction liquid 2412, thereby achieving uniform cold energy distribution on the cold conduction plate 241 and uniform cold energy distribution across the cold conduction plate 241. Therefore, the refrigerator of this embodiment can effectively ensure the consistency of the freezing degree of the food in the drawer cavity 210, improve the freezing quality of the food in the refrigerator, and enhance the user experience.

[0170] Reference Figure 8 In this embodiment, a capillary groove 2413 is provided on the inner wall of the cooling channel 2411 to increase the heat exchange area between the inner wall of the cooling channel 2411 and the cooling liquid 2412 .

[0171] It can be understood that the provision of the capillary groove 2413 can improve the heat exchange rate between the cold conduction plate 241 and the cold conduction liquid 2412, thereby further ensuring the quick freezing effect of the refrigerator on the food and improving the user experience.

[0172] Reference Figure 8 In this embodiment, the capillary grooves 2413 are arranged on the top and bottom walls of the cold conduction channel 2411, thereby improving the heat exchange rate between the bottom and top of the cold conduction plate 241 and the cold conduction liquid 2412, ensuring the heat exchange rate from the cold at the bottom of the cold conduction plate 241 to the top, so as to further ensure the quick freezing effect of the refrigerator on the food and improve the user experience.

[0173] Reference Figure 9 and Figure 10 In this embodiment, the cold conduction channel 2411 is bent and coiled inside the cold conduction plate 241 to ensure that the cold conduction channel 2411 covers the entire cold conduction plate 241, thereby further evenly distributing the cold on the cold conduction plate 241, improving the freezing quality of food in the refrigerator, and enhancing the user experience.

[0174] Specifically, the cooling channel 2411 may be arranged in a multi-segment S-shape, or may be bent and wound from the center of the cooling plate 241 to the outer periphery of the cooling plate 241 .

[0175] Reference Figure 6 and Figure 7 In this embodiment, the cooling member 240 includes a cooling substrate 242 .

[0176] The cooling substrate 242 is disposed between the drawer cavity 210 and the cooling air supply duct 230 . The cooling substrate 242 is attached to the top of the cooling plate 241 . The cooling substrate 242 is used to evenly distribute the cooling energy on the cooling plate 241 .

[0177] In the refrigerator of this embodiment, since the cold conduction member 240 can also include a cold conduction substrate 242 attached to the top of the cold conduction plate 241, the cold conduction substrate 242 can evenly distribute the cold on the cold conduction plate 241 to further ensure the consistency of the freezing degree of the food in the drawer cavity 210, improve the freezing quality of the food in the refrigerator, and enhance the user experience.

[0178] Reference Figure 6 In this embodiment, the cold conduction plate 241 and the cold conduction substrate 242 can be an integrated structure, or the cold conduction plate 241 and the heat exchanger 700 can be an integrated structure, or the cold conduction plate 241, the cold conduction substrate 242 and the heat exchanger 700 can be an integrated structure. The above can avoid limiting the heat exchange between the cold conduction plate 241, the cold conduction substrate 242 and the heat exchanger 700 when other connection methods are used between them, and effectively ensure the overall thermal conductivity of the connection between the heat exchanger 700 and the cold conduction member 240.

[0179] When the cold conduction plate 241 and the cold conduction substrate 242 are an integrated structure, the thickness of the cold conduction plate 241 and the cold conduction substrate 242 in the vertical direction can range from 4 mm to 10 mm to effectively ensure the overall load-bearing capacity of the cold conduction plate 241 and the cold conduction substrate 242.

[0180] Reference Figure 6 In this embodiment, the cooling plate 241 includes a plurality of cooling bodies 2414 arranged along the left-right direction.

[0181] It should be understood that the cooling plate 241 can be formed by connecting multiple cooling bodies 2414, which is convenient for processing. The cooling bodies 2414 can also be plate-shaped.

[0182] Reference Figure 11 、 Figure 12 and Figure 13 In this embodiment, two vertical side walls of the drawer cavity 210 are oppositely arranged with support portions 221 extending in the transverse direction. The support portions 221 are located at the bottom of the drawer cavity 210 , and the cold conduction substrate 242 is mounted on the support portions 221 .

[0183] It is understood that the provision of the support portion 221 allows the heat exchange component 700, the cooling element 240, and its cooling substrate 242 to be disposed at the bottom of the drawer cavity 210, thereby achieving the installation of the heat exchange component 700, the cooling element 240, and its cooling substrate 242. Furthermore, the support portion 221 can ensure that the bottom wall of the drawer cavity 210 as a whole has a large load-bearing capacity.

[0184] Reference Figure 14 and Figure 15 In this embodiment, the freezer drawer 200 includes a front drawer partition 250 and a rear drawer partition 260 .

[0185] The front drawer partition 250 is located between the drawer cavity 210 and the cold conduction and supply air duct 230. The front drawer partition 250 is connected to the front wall of the drawer cavity 210, and the front drawer partition 250 extends backward. The front drawer partition 250 is located in front of the cold conduction plate 241 and the cold conduction substrate 242.

[0186] The rear drawer partition 260 is located between the drawer cavity 210 and the cold conduction and cooling air duct 230. The rear drawer partition 260 is connected to the rear wall of the drawer cavity 210 and extends forward. The rear drawer partition 260 is located behind the cold conduction plate 241 and the cold conduction substrate 242.

[0187] The cooling substrate 242 is connected to the rear end of the front drawer partition 250 and the front end of the rear drawer partition 260 .

[0188] It is understood that the provision of the front drawer partition 250 and the rear drawer partition 260 allows the heat exchange element 700, the cooling element 240, and its cooling substrate 242 to be disposed at the bottom of the drawer cavity 210, thereby enabling installation of the heat exchange element 700, the cooling element 240, and its cooling substrate 242. Furthermore, this ensures that the bottom wall of the drawer cavity 210 as a whole has a greater load-bearing capacity (for example, compared to a situation where the bottom wall of the drawer cavity 210 serves as the upper side of the cooling substrate 242, where the cooling substrate 242 is disposed at the bottom of the drawer cavity 210 via snaps or other means). This also facilitates assembly of the freezer drawer 200.

[0189] Reference Figure 14 and Figure 15 In this embodiment, the rear end of the front drawer partition 250 is provided with a concave front step structure 251, and the front end of the rear drawer partition 260 is provided with a concave rear step structure 261. The cold conduction substrate 242 is mounted on the front step structure 251 and the rear step structure 261 to realize the connection between the cold conduction substrate 242 and the front drawer partition 250 and the rear drawer partition 260, and further ensure that the overall bottom wall of the drawer cavity 210 can have a larger load-bearing capacity, making the assembly of the freezer drawer 200 easier.

[0190] Reference Figure 2 、 Figure 14 、 Figure 15 、 Figure 17 、 Figure 18 and Figure 19 In this embodiment, the freezer drawer 200 includes a drawer bottom plate 270 .

[0191] The drawer bottom plate 270 is located below the cooling member 240 , and the cooling air supply duct 230 is located between the cooling member 240 and the drawer bottom plate 270 .

[0192] A cold air outlet 280 is provided at the lower front end of the freezer drawer 200, and a cold air inlet 290 corresponding to the front of the cold air supply port 170 is provided at the lower rear end of the freezer drawer 200. The cold air supply duct 230 is connected between the cold air outlet 280 and the cold air inlet 290.

[0193] It can be understood that through the setting of the drawer bottom plate 270, the cold air outlet 280 and the cold air inlet 290, the cold air supply duct 230 can be a relatively closed channel, and the refrigerated airflow can be restricted to flow in a relatively closed space to avoid the loss of refrigerated airflow and cold capacity, thereby ensuring the freezing performance and quick-freezing effect of the refrigerator.

[0194] Reference Figure 17 、 Figure 18 and Figure 19 In this embodiment, the cooling air outlet 280 is connected to the return air section 151 to allow the refrigerated air flow in the cooling air supply duct 230 to flow back into the evaporation compartment 140 .

[0195] It can be understood that by connecting the cold air outlet 280 to the return air section 151, the refrigerated air flow that exchanges heat with the cold air component 240 and the heat exchange component 700 and flows out through the cold air outlet 280 can flow back to the evaporation compartment 140 to exchange heat with the evaporator 141, and the refrigerated air flow after heat exchange with the evaporator 141 continues to be transported to the cold air supply port 170 (and / or the cold air supply port 130), thereby realizing the circulation of the refrigerated air flow and ensuring the operation of the refrigerator.

[0196] Reference Figure 17 In this embodiment, a cooling fan 281 is provided at the cooling air outlet 280 , and the cooling fan 281 is used to guide the refrigerated air flow in the cooling air supply duct 230 to flow into the return air section 151 .

[0197] It can be understood that by setting up the cooling fan 281, the flow rate of the refrigerated air flow flowing from the cooling air supply port 170 into the cooling air supply duct 230 can be effectively guaranteed, so as to further ensure the cold amount exchanged to the cooling component 240, ensure the quick freezing effect of the refrigerator on the food, and improve the user experience.

[0198] Reference Figure 17 In the first implementation of the evaporation cabin 140 of this embodiment, a freezing chamber 180 is further provided in the box body 100. The freezing chamber 180 is used to freeze the food stored therein. The freezing chamber 180 is located below the freezing compartment 110. A freezing partition assembly 190 is provided between the freezing compartment 110 and the freezing chamber 180, so that the freezing compartment 110 and the freezing chamber 180 can be separated into two relatively independent chambers by the freezing partition assembly 190.

[0199] In addition, the return air duct 150 also includes an air supply section 152 located below the drawer bottom plate 270 and above the freezing partition assembly 190, and a return air port 111 is provided at the rear of the freezing compartment 110. The return air port 111 is provided corresponding to the air supply section 152, and the front end of the air supply section 152 is connected to the bottom end of the return air section 151, and the rear end of the air supply section 152 is connected to the return air port 111, and the return air port 111 is connected to the evaporation compartment 140.

[0200] It can be understood that the refrigerated airflow flowing out of the drawer cavity 210 through the moisturizing air outlet 500 and / or the refrigerated airflow flowing out of the cooling supply air duct 230 through the cooling air outlet 280 can flow back to the evaporation compartment 140 through the air supply section 152 and the return air outlet 111.

[0201] Moreover, since the air supply section 152 is located below the drawer bottom plate 270, the refrigerated airflow in the air supply section 152 can continue to contact the drawer bottom plate 270, and the refrigerated airflow in the air supply section 152 can continue to cool the freezer drawer 200, so as to further ensure the freezing performance of the refrigerator and the quick-freezing effect on the food.

[0202] In this embodiment, return air baffles are provided in the freezing chamber 180 and the freezer compartment 110. An air supply section of the return air duct 150 is formed between the return air baffle and the left and / or right walls of the freezing chamber 180 and the freezer compartment 110. A return air port 111 is provided on the return air baffle, with the top end of the air supply section connected to the return air port 111 and the bottom end of the air supply section connected to the evaporation compartment 140. This allows for communication between the return air port 111 and the evaporation compartment 140.

[0203] Reference Figure 18 and Figure 19 In the second embodiment of the evaporation compartment 140 of this embodiment, an evaporation partition 142 is provided at the lower portion of the freezer compartment 110 to separate the evaporation compartment 140 from the lower portion of the freezer compartment 110. A return air port 111 is provided at the front end of the evaporation partition 142, connecting to the evaporation compartment 140. The bottom end of the return air section 151 is also connected to the return air port 111. Consequently, the refrigerated airflow flowing into the return air section 151 through the moisturizing air outlet 500 and / or the refrigerated airflow flowing into the return air section 151 through the cooling air outlet 280 can flow directly downward through the return air port 111 and back to the evaporation compartment 140.

[0204] Reference Figure 18 and Figure 19In this embodiment, the cold air supply duct 230 can be located below the freezer drawer 200 and on top of the other freezer drawer 200. That is, the drawer in this embodiment does not need to be provided with a drawer bottom plate 270, a cold air outlet 280, and a cold air inlet 290. The lower side of the cold plate 241, the front drawer partition 250, and the rear drawer partition 260 is the outer bottom surface of the freezer drawer 200. Then, the refrigerated air flow flowing out of the cold air supply duct 230 flows into the return air section 151, flows downward through the return air port 111, and flows back to the evaporation compartment 140. Of course, the drawer in this embodiment can also be provided with a drawer bottom plate 270, a cold air outlet 280, and a cold air inlet 290.

[0205] Reference Figure 11 、 Figure 12 and Figure 13 In this embodiment, a drainage portion 211 is provided at the bottom of the drawer cavity 210 , and the drainage portion 211 is used to allow the water in the drawer cavity 210 to be discharged to the outside of the drawer cavity 210 .

[0206] In this embodiment, the refrigerator has a drain 211 at the bottom of the drawer 210, which allows water inside the drawer 210 to drain outside the drawer 210. When moisture in the air inside the drawer 210 condenses into water, the water is drained outside the drawer 210 through the drain 211, eliminating any ice buildup inside the drawer 210. Therefore, this embodiment eliminates the need for users to regularly clean ice from the drawer 210, effectively ensuring a superior user experience.

[0207] Reference Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 and Figure 13 In this embodiment, the drainage portion 211 is located between the cooling member 240 and the vertical side wall of the drawer cavity 210 , and the drainage portion 211 is used to allow water in the drawer cavity 240 to flow into the cooling air duct 230 .

[0208] It is understandable that the water in the drawer cavity 210 can be discharged into the cooling air duct 230 to discharge the water to the outside of the drawer cavity 210 through the drainage portion 211, so that no ice chips will remain in the drawer cavity 210.

[0209] Reference Figure 12 、 Figure 13 、 Figure 14 and Figure 15 In this embodiment, the drainage portion includes a drainage gap 212 .

[0210] The drainage gap 212 is located between the cooling substrate 242 and the vertical side wall of the drawer cavity 210 . The drainage gap 212 is used to allow water in the drawer cavity 210 to flow into the cooling air supply duct 230 .

[0211] It can be understood that the drainage portion 211 can be a drainage gap 212 set between the cooling substrate 242 and the vertical side wall of the drawer cavity 210, and then the drainage portion 211 can discharge the water in the drawer cavity 210 into the cooling air duct 230.

[0212] Figure 11 、 Figure 12 and Figure 13 , refer to Figure 11 、 Figure 12 and Figure 13 In this embodiment, the drainage portion 211 includes a first gap 212 and a second gap 2122 .

[0213] The first gap 2121 is located between the left side wall of the drawer cavity 210 and the left end of the cooling substrate 242 . The first gap 2121 is used to allow water in the drawer cavity 210 to flow into the cooling air supply duct 230 .

[0214] The second gap 2122 is located between the right side wall of the drawer cavity 210 and the right end of the cooling substrate 242 . The second gap 2122 is used to allow water in the drawer cavity 210 to flow into the cooling air supply duct 230 .

[0215] It can be understood that the drainage portion 211 can be a first gap 2121 and a second gap 2122 arranged between the cold conduction substrate 242 and the left and right walls of the drawer cavity 210, so that the drainage portion 211 can discharge the water in the drawer cavity 210 to the outside of the drawer cavity 210.

[0216] Reference Figure 12 、 Figure 13 、 Figure 14 and Figure 15 In this embodiment, the drainage portion 211 includes a drainage gap 213 .

[0217] The drainage gap 213 is located at the end portion of the support portion 221 extending laterally, and the drainage gap 213 is located between the vertical side wall of the drawer cavity 210 and the cold conduction plate 241. The drainage gap 213 is located below the drainage gap 212. The drainage gap 213 and the drainage gap 212 are used to allow water in the drawer cavity 210 to flow into the cold conduction and supply air duct 230.

[0218] It is understandable that since the cold-conducting substrate 242 is arranged at the bottom of the drawer cavity 210 through the support portion 221, the support portion 221 will hinder the flow of water flowing through the drainage gap 212 to the lower left and right ends of the cold-conducting substrate 242. Therefore, a drainage gap 213 can be provided on the support portion 221 or at the end of the support portion 221. Then, when the water flows to the lower part of the cold-conducting substrate 242 through the drainage gap 212, it will continue to flow out of the drawer cavity 210 through the drainage gap 213. Then, by setting the drainage gap 213 and the drainage gap 212, the drainage portion 211 can allow the water in the drawer cavity 210 to flow to the outside of the drawer cavity 210 (inside the cold-conducting cooling air duct 230).

[0219] Reference Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 In this embodiment, the support portion 221 may include a first support bar 2211 and a second support bar 2212 .

[0220] A first support bar 2211 is disposed on the left side wall of the drawer cavity 210 and extends in the front-to-back direction. A second support bar 2212 is disposed on the right side wall of the drawer cavity 210 and extends in the front-to-back direction. The cooling substrate 242 is mounted on the first and second support bars 2211 and 2212.

[0221] The front drawer partition 250 is located in front of the first support bar 2211 and the second support bar 2212 .

[0222] The drainage gap 213 includes a first gap 2131 and a second gap 2132 .

[0223] The first notch 2131 is located between the front drawer partition 250 and the first support bar 2211. The first notch 2131 is located below the first gap 2121. The first notch 2131 and the first gap 2121 are used to allow water in the drawer cavity 210 to flow into the cold air supply duct 230.

[0224] The second notch 2132 is located between the front drawer partition 250 and the second support bar 2212 , and the second notch 2132 is located below the second gap 2122 . The second notch 2132 and the second gap 2122 are used to allow water in the drawer cavity 210 to flow into the cold air supply duct 230 .

[0225] It is understood that the drainage gap 213 can be provided by providing a first gap 2131 between the rear end of the front drawer partition 250 and the first support bar 2211, and a second gap 2132 between the rear end of the front drawer partition 250 and the second support bar 2212. When water flows through the first gap 2121 to the lower left end of the cold conduction substrate 242, it will continue to flow out of the drawer cavity 210 through the first gap 2131; when water flows through the second gap 2122 to the lower right end of the cold conduction substrate 242, it will continue to flow out of the drawer cavity 210 through the second gap 2132. Furthermore, through the provision of the first gap 2121 and the first gap 2131, as well as the second gap 2122 and the second gap 2132, the drainage portion 211 can allow water in the drawer cavity 210 to flow outside the drawer cavity 210.

[0226] In other embodiments, the drawer bottom plate 270 (or the cooling air duct 230) is tilted downward from front to back, and a water supply channel is provided at the rear of the freezer compartment 110, one end of the water supply channel is connected to the rear end of the cooling air duct 230, and the other end of the water supply channel is connected to the water receiving pan provided below the evaporator 141.

[0227] Alternatively, the drawer bottom plate 270 (or the cooling air supply duct 230) is arranged to be tilted upward from front to back, and a water supply channel is provided at the front of the freezer compartment 110, one end of the water supply channel is connected to the front end of the cooling air supply duct 230, and the other end of the water supply channel is connected to the water receiving pan provided below the evaporator 141.

[0228] As described above, the water flowing from the drawer cavity into the cooling air duct 230 can flow into the water receiving tray through the cooling air outlet 280 / cooling air inlet 290 and the water supply channel, thereby preventing the water from flowing onto the indoor floor and ensuring the user experience.

[0229] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
