Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator. Background Technology

[0002] With the development of science and technology, people's living standards are constantly improving. Refrigerator technology is also constantly being iterated and updated to meet people's needs.

[0003] Currently, in existing technology, the freezer compartment of a frost-free refrigerator is equipped with a freezer drawer. Freezing airflow is forced to circulate around the freezer drawer to freeze the food inside. This way, the freezing airflow does not directly contact the food inside the drawer, and the airflow does not blow directly onto the food, thus better preventing moisture loss. However, this freezing method is slow and cannot meet the storage needs of some foods that require rapid freezing (such as seafood), thereby failing to meet user needs and resulting in a reduced user experience. Utility Model Content

[0004] One objective of this invention is to provide a refrigerator that can solve at least one of the technical defects in the prior art.

[0005] A further objective of this invention is to enable the refrigerator to freeze food quickly, thereby meeting users' needs for rapid freezing of food and improving the user experience.

[0006] Specifically, this utility model provides a refrigerator, which includes:

[0007] The cabinet contains a freezer compartment.

[0008] A freezer drawer, located within a freezer compartment, has a cooling air duct between one end of it and the side wall of the freezer compartment. The drawer contains a drawer cavity, including:

[0009] The inflated bottom plate is arranged horizontally at the bottom of the drawer cavity, with its end extending to the cooling air duct. It has a cavity flow channel filled with a heat-conducting working fluid.

It is arranged in the vertical direction, and its bottom end is connected to the left end of the first expansion plate. It is used to exchange heat with the freezing airflow in the first cooling channel and the first expansion plate.

[0018] The fourth expansion plate is located on the right side of the drawer cavity and on the left side of the second cooling channel. It is arranged in the vertical direction, and its bottom end is connected to the right end of the second expansion plate. It is used to exchange heat with the freezing airflow in the second cooling channel and the second expansion plate.

[0019] Furthermore, the freezer drawer includes:

[0020] The metal plate on the left side is fitted onto the side of the third blow-up plate facing the drawer cavity;

[0021] The metal plate on the right side is attached to the side of the fourth blow plate facing the drawer cavity;

[0022] A metal base plate, with its left end connected to the left side metal plate and its right end connected to the right side metal plate, is located at the bottom of the drawer cavity. The weight-avoiding cavity is located between the blown base plate and the metal base plate, and the lower side of the metal base plate is attached to the top surface of the heat-conducting block.

[0023] Furthermore, the first and third inflation plates are an integral structure; and,

[0024] The second and fourth inflation plates are an integral structure.

[0025] Furthermore, the refrigerator includes:

[0026] A first heat exchanger, disposed within a first cooling channel, is connected to a third blow-up plate and extends to the left; and...

[0027] The second heat exchanger is located in the second cooling channel and is connected to the fourth blow plate and extends to the right.

[0028] Furthermore, the first heat exchanger includes:

[0029] The first heat exchange fin is disposed within the first cooling channel, connected to the third blown plate and extending to the left, and also extending in the front-to-back direction within the first cooling channel; and,

[0030] The second heat exchanger includes:

[0031] The second heat exchange fin is disposed in the second cooling channel, connected to the fourth expansion plate and extending to the right, and extending in the front-to-back direction in the second cooling channel.

[0032] Furthermore, a first cold air inlet is provided at the rear of the freezer compartment and at the rear end of the first cooling aisle. The first cold air inlet extends vertically and is used to provide cooling airflow into the first cooling aisle; and,

[0033] The number of first heat exchange fins is set to multiple, and the multiple first heat exchange fins are arranged vertically within the first cooling channel; and...

[0034] A second cold air inlet is provided at the rear of the freezer compartment and at the rear end of the second cooling aisle. The second cold air inlet extends vertically and is used to provide cooling airflow into the second cooling aisle; and...

The first cooling channel is located between the left end of the freezer drawer and the left side wall of the freezer compartment, and the second cooling channel is located between the right end of the freezer drawer and the right side wall of the freezer compartment; and,

[0037] The cabinet contains an evaporator chamber for housing the refrigerator's evaporator and a return air duct connecting to the evaporator chamber; and,

[0038] The return air duct includes a return air section located in front of the freezer drawer. The front ends of the first cooling channel and the second cooling channel are both connected to the return air section to allow the refrigerant airflow in the first cooling channel and the second cooling channel to flow back into the evaporator chamber.

[0039] This refrigerator's freezer drawer includes a horizontally arranged inflated bottom plate at the bottom of the drawer cavity, with one end extending to a cooling air duct. Food to be frozen can be placed inside the drawer cavity on the inflated bottom plate. The inflated bottom plate exchanges cold air with the cooling airflow through its extended end, directly transferring the cold air to the food and promoting freezing. Specifically, the inflated plate has a cavity channel, at least partially filled with a heat-conducting medium. When the liquid heat-conducting medium exchanges heat with the food placed on the inflated bottom plate, it changes phase to gas and then flows towards the portion extending to the cooling air duct. In this portion, the heat-conducting medium is cooled by the cooling airflow, changes phase to liquid, and then flows back to the bottom of the drawer cavity, continuously transporting the cold airflow to the bottom of the drawer cavity. Therefore, compared to ordinary plastic or metal freezer drawers, the inflated bottom plate has a higher thermal conductivity and faster heat transfer speed. Therefore, this invention enables refrigerators to freeze food quickly, meeting users' needs for rapid freezing and improving the user experience.

[0056] The following is combined with Figures 1 to 8 The refrigerator of this embodiment will be described in detail below. Among them, Figure 7 and Figure 8 The hollow arrows in the diagram indicate the flow path and direction of the refrigeration airflow.

[0057] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the refrigerator includes a cabinet 100 and a freezer drawer 200.

[0058] The cabinet 100 is equipped with a freezer compartment 110.

[0059] A freezer drawer 200 is installed inside the freezer compartment 110. A cooling air duct 120 is provided between one end of the freezer drawer 200 and the side wall of the freezer compartment 110. A drawer cavity 210 is provided inside the freezer drawer 200.

[0060] The freezer drawer 200 includes an inflated bottom plate 220. The inflated bottom plate 220 is arranged laterally at the bottom of the drawer cavity 210, and the end of the inflated bottom plate 220 extends to the cooling air duct 120. A cavity flow channel 221 is provided inside the inflated bottom plate 220, and the cavity flow channel 221 is filled with a heat-conducting working fluid 222. The inflated bottom plate 220 is used to exchange heat with the freezing airflow in the cooling air duct 120 to cool the food in the drawer cavity 210.

[0061] In this embodiment, the freezer drawer 200 includes an inflatable bottom plate 220 arranged laterally at the bottom of the drawer cavity 210, with one end of the inflatable bottom plate 220 extending to the cooling air duct 120. Food items to be frozen can be placed inside the drawer cavity 210 on the inflatable bottom plate 220. The inflatable bottom plate 220 can exchange cold air with the freezing airflow through the portion extending to the cooling air duct 120, directly transferring the cold air to the food items and causing them to freeze. Specifically, a cavity flow channel 221 is formed inside the inflatable plate, and at least a portion of the cavity flow channel 221 is filled with a thermally conductive working fluid 222. When the liquid heat-conducting medium 222 exchanges heat with the food placed on the inflated bottom plate 220, it changes phase to gas. Then, a portion of the medium extends from the inflated bottom plate 220 to the cooling air duct 120. In this portion, the heat-conducting medium 222 is cooled by the freezing airflow, changes phase back to liquid, and then flows back to the bottom of the drawer cavity 210, continuously transporting the cold airflow to the bottom of the drawer cavity 210. Therefore, compared to ordinary plastic freezer drawers 200 or ordinary metal drawers, the inflated bottom plate 220 has a higher thermal conductivity and a faster heat transfer speed. Thus, this embodiment enables the refrigerator to quickly freeze food, meeting the user's need for rapid freezing and improving the user experience.

[0062] Reference Figure 4 In this embodiment, at least a portion of the inflatable base plate 220 extends downward to form a weight-avoiding cavity 230 above the inflatable base plate 220.

[0063] A heat-conducting block 240 is provided inside the weight-avoiding cavity 230. The heat-conducting block 240 is located below the drawer cavity 210, and the bottom surface of the heat-conducting block 240 is attached to the upper side of the blown bottom plate 220. The top surface of the heat-conducting block 240 extends horizontally.

[0064] Understandably, because the inflatable base plate 220 uses an inflatable process to create a cavity flow channel 221 within it, the walls of the inflatable base plate 220 above and below the cavity flow channel 221 are relatively thin, and the overall thickness of the inflatable base plate 220 is also relatively thin. Consequently, the thermal conductivity of the inflatable base plate 220 is relatively high after being filled with the thermally conductive working fluid 222. However, this reduces the load-bearing capacity of the inflatable base plate 220 / drawer cavity 210 bottom. When a user places food on the inflatable base plate 220 inside the drawer cavity 210, the weight of the food may cause the inflatable base plate 220 to bend, or cause the cavity flow channel 221 to collapse, or even render the inflatable base plate 220 unusable. Therefore, by setting up the weight-avoiding cavity 230 and the heat-conducting block 240, the inflated bottom plate 220 can be kept away from the bottom of the drawer cavity 210. When the user places food in the drawer cavity 210, the food can be placed on the heat-conducting block 240, thereby preventing the weight of the food from being directly applied to the inflated bottom plate 220. This effectively prevents the inflated bottom plate 220 from being bent and the cavity flow channel 221 from being crushed, ensuring the service life of the inflated bottom plate 220. At the same time, it ensures the load-bearing capacity of the bottom of the drawer cavity 210 and ensures the user experience of the refrigerator and freezer drawer 200.

[0065] Furthermore, the heat-conducting block 240 can exchange the cold energy on the inflated base plate 220 with the food placed on the heat-conducting block 240, so as to freeze the food and cool the drawer cavity 210.

[0066] Furthermore, the top surface of the heat-conducting block 240 extends horizontally, which ensures the stability of food placed on the top surface of the heat-conducting block 240.

[0067] In addition, the fact that at least a portion of the inflated base plate 220 extends downwards allows the heat transfer medium 222 inside it to flow back smoothly after the phase change to liquid state, thereby increasing the power of the circulation of the heat transfer medium 222 within the inflated base plate 220 and further ensuring the speed and effectiveness of the refrigerator in freezing food.

[0068] Reference Figure 4 In this embodiment, both the upper side of the blown base plate 220 and the bottom surface of the heat-conducting block 240 can be set as planes so that the bottom surface of the heat-conducting block 240 is attached to the upper side of the blown base plate 220.

[0069] In this embodiment, the upper side of the blown base plate 220 is provided with a flow channel protrusion corresponding to the cavity flow channel 221. Furthermore, the bottom surface of the heat-conducting block 240 is provided with a flow channel clearance groove corresponding to the flow channel protrusion, and the flow channel protrusion is disposed within the flow channel clearance groove. This allows the bottom surface of the heat-conducting block 240 to fit snugly against the upper side of the blown base plate 220, preventing damage to the blown plate and the cavity flow channel 221.

[0070] In this embodiment, the material of the blown base plate 220 may include at least one of aluminum and copper.

[0071] Reference Figure 2 and Figure 4 In this embodiment, the cooling air duct 120 includes a first cooling channel 121 and a second cooling channel 122 extending in the front-back direction. The first cooling channel 121 is located between the left end of the freezer drawer 200 and the left side wall of the freezer compartment 110, and the second cooling channel 122 is located between the right end of the freezer drawer 200 and the right side wall of the freezer compartment 110.

[0072] Reference Figure 2 and Figure 4 In this embodiment, the inflatable base plate 220 includes a first inflatable plate 223 and a second inflatable plate 224.

[0073] The left end of the first inflation plate 223 extends to the first cooling channel 121, and the right end of the first inflation plate 223 is inclined to the lower right.

[0074] The right end of the second blow-up plate 224 extends to the second cooling channel 122, and the left end of the second blow-up plate 224 is inclined to the lower left and connected to the right end of the first blow-up plate 223. The heat-conducting block 240 is disposed above the first blow-up plate 223 and the second blow-up plate 224.

[0075] It is understood that the inflatable base plate 220 may include a first inflatable plate 223 and a second inflatable plate 224. The right end of the first inflatable plate 223 is inclined downward to the right, and the left end of the second inflatable plate 224 is inclined downward to the left and connected to the right end of the first inflatable plate 223, so as to cause at least a portion of the inflatable base plate 220 to extend downward, and to form a weight-avoiding cavity 230.

[0076] It is important to understand that if the inflatable base plate 220 is a single piece of board, and it is inclined downwards from left to right, then if the inclination angle of the inflatable base plate 220 is the same as that of the first inflatable plate 223 / second inflatable plate 224 in this embodiment, the vertical extension height of the inflatable base plate 220 will be greater than that of the first inflatable plate 223 / second inflatable plate 224 in this embodiment. This would result in a larger volume of the weight-avoiding cavity 230, thus reducing the effective volume of the freezer drawer 200. Therefore, by dividing the inflatable base plate 220 into a first inflatable plate 223 and a second inflatable plate 224 connected in the middle, and by extending the connection point of the first inflatable plate 223 and the second inflatable plate 224 downwards, the entire inflatable base plate 220 can be moved away from the drawer cavity 210, minimizing the volume of the weight-avoiding cavity 230, thus ensuring the effective volume of the freezer drawer 200 and guaranteeing a better user experience.

[0077] Reference Figure 2 and Figure 4In this embodiment, the freezer drawer 200 includes a third inflatable plate 250 and a fourth inflatable plate 260.

[0078] The third blow-out plate 250 is located on the left side of the drawer cavity 210 and on the right side of the first cooling channel 121. The third blow-out plate 250 is arranged in the vertical direction. The bottom end of the third blow-out plate 250 is connected to the left end of the first blow-out plate 223. The third blow-out plate 250 is used to exchange heat with the freezing airflow in the first cooling channel 121 and the first blow-out plate 223.

[0079] The fourth blow-out plate 260 is located on the right side of the drawer cavity 210 and on the left side of the second cooling channel 122. The fourth blow-out plate 260 is arranged in the vertical direction. The bottom end of the fourth blow-out plate 260 is connected to the right end of the second blow-out plate 224. The fourth blow-out plate 260 is used to exchange heat with the freezing airflow in the second cooling channel 122 and the second blow-out plate 224.

[0080] It is understood that the left and right side walls of the freezer drawer 200 can be formed by a third blow-up plate 250 and a fourth blow-up plate 260. The surface of the third blow-up plate 250 facing the first cooling channel 121 and the surface of the fourth blow-up plate 260 facing the second cooling channel 122 will be in complete contact with the freezing airflow, thus allowing the third blow-up plate 250 and the fourth blow-up plate 260 to exchange a larger amount of cold air with the freezing airflow. Furthermore, the third blow-up plate 250 and the fourth blow-up plate 260 are correspondingly connected to the first blow-up plate 223 and the second blow-up plate 224 to exchange this cold airflow onto the blow-up base plate 220. Therefore, the arrangement of the third blow-up plate 250 and the fourth blow-up plate 260 in this embodiment can effectively increase the amount of cold air exchanged onto the blow-up base plate 220, further improving the freezing speed of food in the refrigerator and further ensuring the user experience.

[0081] Specifically, the third blown plate 250 and the fourth blown plate 260 can also be blown structures, that is, both the third blown plate 250 and the fourth blown plate 260 are provided with cavity flow channels 221, and the cavity flow channels 221 are filled with heat-conducting working fluid 222. Then, when the liquid heat-conducting working fluid 222 at the bottom of the third blown plate 250 and the fourth blown plate 260 exchanges heat with the blown base plate 220 and changes to a gaseous state, it will flow upwards towards the third blown plate 250 and the fourth blown plate 260. Furthermore, after the gaseous heat-conducting working fluid 222 in the third blown plate 250 and the fourth blown plate 260 is cooled by the freezing airflow, it will change to a liquid state and flow back to the bottom of the third blown plate 250 and the fourth blown plate 260, thereby allowing the third blown plate 250 and the fourth blown plate 260 to exchange the cooling capacity of the freezing airflow onto the blown base plate 220.

[0082] Furthermore, since the left and right side walls of the drawer cavity 210 can be formed by the third expansion plate 250 and the fourth expansion plate 260, the cold energy exchanged by the third expansion plate 250 and the fourth expansion plate 260 can directly cool the drawer cavity 210 and the food inside that is in contact with the third expansion plate 250 and the fourth expansion plate 260, thereby further improving the speed of freezing food in the refrigerator and further ensuring the user experience.

[0083] In addition, the materials of the third inflation plate 250 and the fourth inflation plate 260 may include at least one of aluminum and copper.

[0084] Reference Figure 4 In this embodiment, the first inflation plate 223 and the third inflation plate 250 are integral structures; and the second inflation plate 224 and the fourth inflation plate 260 are integral structures.

[0085] Understandably, by making the first expansion plate 223 and the third expansion plate 250 into a single structure, the loss of cold energy during the exchange from the third expansion plate 250 to the first expansion plate 223 can be effectively reduced, ensuring the refrigerator's rapid freezing effect on food. Similarly, by making the second expansion plate 224 and the fourth expansion plate 260 into a single structure, the refrigerator's rapid freezing effect on food can be further guaranteed.

[0086] Specifically, when the heat-conducting medium 222 in the first blown plate 223 exchanges heat with the food through the heat-conducting block 240, it changes to a gaseous state. Then, the gaseous heat-conducting medium 222 flows into the third blown plate 250 and is cooled by the freezing airflow, changing into a liquid heat-conducting medium 222. Furthermore, the liquid heat-conducting medium 222 flows back from the third blown plate 250 to the first blown plate 223, exchanging cold energy with the food through the heat-conducting block 240 to cool the drawer cavity 210 and freeze the food.

[0087] When the heat-conducting medium 222 in the second blown plate 224 exchanges heat with the food through the heat-conducting block 240, it changes to a gaseous state. Then, the gaseous heat-conducting medium 222 flows into the fourth blown plate 260 and is cooled by the freezing airflow, changing into a liquid heat-conducting medium 222. Furthermore, the liquid heat-conducting medium 222 flows back from the fourth blown plate 260 to the second blown plate 224, exchanging cold energy with the food through the heat-conducting block 240 to cool the drawer cavity 210 and freeze the food.

[0088] Reference Figure 4 In this embodiment, the freezer drawer 200 may also include a left metal plate 271, a right metal plate 272 and a metal bottom plate 273.

[0089] The left metal plate 271 is attached to the side of the third blow plate 250 facing the drawer cavity 210.

[0090] The right-side metal plate 272 is attached to the side of the fourth inflatable plate 260 facing the drawer cavity 210.

[0091] The left end of the metal base plate 273 is connected to the left side metal plate 271, and the right end of the metal base plate 273 is connected to the right side metal plate 272. The metal base plate 273 is located at the bottom of the drawer cavity 210. The weight-avoiding cavity 230 is located between the blown base plate 220 and the metal base plate 273, and the lower side of the metal base plate 273 is attached to the top surface of the heat-conducting block 240.

[0092] Understandably, the arrangement of the left metal plate 271, right metal plate 272, and metal base plate 273 further ensures the overall load-bearing capacity and deformation resistance of the freezer drawer 200, effectively guaranteeing its service life. Simultaneously, the left metal plate 271, right metal plate 272, and metal base plate 273 can exchange the cold air from the third expansion plate 250, fourth expansion plate 260, and expansion base plate 220 to the freezer cavity and the food. Furthermore, the left metal plate 271, right metal plate 272, and metal base plate 273 can evenly distribute the cold air from the third expansion plate 250, fourth expansion plate 260, and expansion base plate 220, preventing inconsistent freezing of food during freezing and ensuring the quality of the frozen food.

[0093] Reference Figure 3 and Figure 4 In this embodiment, the freezer drawer 200 may further include a front side plate 274 connected to the front of the inflated bottom plate 220, the third inflated plate 250, the fourth inflated plate 260, the left metal plate 271, the right metal plate 272 and the metal bottom plate 273, and a rear side plate 275 connected to the rear of the inflated bottom plate 220, the third inflated plate 250, the fourth inflated plate 260, the left metal plate 271, the right metal plate 272 and the metal bottom plate 273. The front side plate 274 may form the front side wall of the drawer cavity 210, and the rear side plate 275 may form the rear side wall of the drawer cavity 210.

[0094] Furthermore, the front panel 274 and the rear panel 275 can be metal parts. More specifically, the materials of both the front panel 274 and the rear panel 275 can include at least one of aluminum and copper. This further improves the refrigerator's freezing speed and ensures a better user experience.

[0095] Reference Figure 2 and Figure 3 In this embodiment, the refrigerator includes a first heat exchanger 310 and a second heat exchanger 320.

[0096] The first heat exchanger 310 is disposed in the first cooling channel 121, and the first heat exchanger 310 is connected to the third blow plate 250 and extends to the left.

[0097] The second heat exchanger 320 is disposed in the second cooling channel 122, and is connected to the fourth blow plate 260 and extends to the right.

[0098] It is understandable that by setting the first heat exchanger 310 and the second heat exchanger 320, the heat exchange area between the third blow plate 250 and the freezing airflow and the fourth blow plate 260 and the freezing airflow can be increased respectively, so as to increase the amount of cold air exchanged by the third blow plate 250 and the fourth blow plate 260, thereby further increasing the speed of freezing food in the refrigerator and further ensuring the user experience.

[0099] Reference Figure 4 In this embodiment, the first heat exchanger 310 includes a first heat exchange fin 311. The first heat exchanger 310 also includes a second heat exchange fin 321.

[0100] The first heat exchange fin 311 is disposed in the first cooling channel 121. The first heat exchange fin 311 is connected to the third blow plate 250 and extends to the left. The first heat exchange fin 311 extends in the front-to-back direction in the first cooling channel 121.

[0101] The second heat exchange fin 321 is disposed in the second cooling channel 122. The second heat exchange fin 321 is connected to the fourth blow plate 260 and extends to the right. The second heat exchange fin 321 extends in the front-to-back direction in the second cooling channel 122.

[0102] It is understood that both the first heat exchanger 310 and the second heat exchanger 320 can be heat exchange fins, thereby increasing the heat exchange area between the third blown plate 250 and the refrigeration airflow, as well as the heat exchange area between the fourth blown plate 260 and the refrigeration airflow.

[0103] In a modified embodiment, the first heat exchanger 310 may be a first heat exchange column / needle connected to the third blown plate 250 and extending to the left, and the second heat exchanger 320 may be a second heat exchange column / needle connected to the fourth blown plate 260 and extending to the right, so as to increase the heat exchange area between the third blown plate 250 and the refrigeration airflow and the heat exchange area between the fourth blown plate 260 and the refrigeration airflow.

[0104] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 In this embodiment, a first cold air supply port 130 is provided at the rear of the freezer compartment 110 and the rear end of the first cold supply channel 121. The first cold air supply port 130 extends in the vertical direction and is used to provide freezing airflow into the first cold supply channel 121.

[0105] The number of first heat exchange fins 311 is set to multiple, and the multiple first heat exchange fins 311 are arranged in the first cooling channel 121 in the vertical direction.

[0106] A second cooling air inlet 140 is provided at the rear of the freezer compartment 110 and at the rear end of the second cooling channel 122. The second cooling air inlet 140 extends in the vertical direction and is used to provide cooling airflow into the second cooling channel 122.

[0107] The number of second heat exchange fins 321 is set to multiple, and the multiple second heat exchange fins 321 are arranged in the vertical direction in the second cooling channel 122.

[0108] It is understandable that by setting the number of first heat exchange fins 311 and second heat exchange fins 321 to multiple, the amount of cooling exchanged by the third expansion plate 250 and the fourth expansion plate 260 can be further increased, thereby further ensuring the user experience.

[0109] Furthermore, the first cooling air inlet 130 and the second cooling air inlet 140 extend vertically, effectively ensuring the flow rate of the freezing air into the first cooling channel 121 and the second cooling channel 122. This further improves the speed at which the refrigerator freezes food and enhances the user experience.

[0110] In addition, multiple first heat exchange fins 311 are set to correspond to the first cold air supply port 130, and multiple second heat exchange fins 321 are set to correspond to the second cold air supply port 140, so as to ensure the heat exchange efficiency of the first heat exchange element 310, the second heat exchange element 320 and the refrigeration airflow.

[0111] Reference Figure 7 and Figure 8 In this embodiment, the cabinet 100 is provided with an evaporation chamber 150 for placing the evaporator 400 of the refrigerator and a return air duct 160 connected to the evaporation chamber 150.

[0112] The return air duct 160 includes a return air section 161 located in front of the freezer drawer 200. The front ends of the first cooling channel 121 and the second cooling channel 122 are both connected to the return air section 161 to allow the refrigerant airflow in the first cooling channel 121 and the second cooling channel 122 to flow back into the evaporator chamber 150.

[0113] Understandably, by setting up the return air duct 160, the refrigerant airflow flowing in the cooling air duct 120 (first cooling channel 121 and second cooling channel 122) can flow back to the evaporator chamber 150 to exchange heat with the evaporator 400. After exchanging heat with the evaporator 400, the refrigerant airflow is continued to be transported to the first cooling air outlet 130 and the second cooling air outlet 140, thereby realizing the circulation of refrigerant airflow and ensuring the operation of the refrigerator.

[0114] Reference Figure 1 and Figure 6 In this embodiment, a storage and retrieval port 111 is provided in front of the freezer compartment 110, and the refrigerator includes a drawer door 700. The drawer door 700 is located at the storage and retrieval port 111 and is connected to the front of the freezer drawer 200. The return air section 161 is located between the drawer door 700 and the freezer drawer 200.

[0115] Reference Figure 2 and Figure 6 In this embodiment, the refrigerator includes an air duct plate 500, which is disposed at the rear of the freezer compartment 110. An air supply duct 510 is formed between the air duct plate 500 and the rear wall of the freezer compartment 110. A first cold air supply port 130 and a second cold air supply port 140 are opened on the air duct plate 500 and are connected to the air supply duct 510. The bottom of the air supply duct 510 is connected to the evaporator chamber 150. After exchanging heat with the evaporator 400, the refrigerant airflow flows out of the evaporator chamber 150 and then flows through the air supply duct 510 to the first cold air supply port 130 and the second cold air supply port 140.

[0116] Reference Figure 7 and Figure 8 In this embodiment, an evaporation baffle 600 is provided in the lower part of the freezer compartment 110 to separate the evaporation chamber 150 in the lower part of the freezer compartment 110.

[0117] Reference Figure 7 In the first embodiment of the evaporation chamber 150 of this example, a freezing chamber 170 is also provided inside the box 100. The freezing chamber 170 is used to freeze the food stored inside. The freezing chamber 170 is located below the freezing compartment 110. A freezing partition assembly 180 is provided between the freezing compartment 110 and the freezing chamber 170, so that the freezing compartment 110 and the freezing chamber 170 can be separated into two relatively independent chambers by the freezing partition assembly 180.

[0118] Furthermore, the return air duct 160 also includes an air supply section 162 located below the freezer drawer 200 and above the freezer partition assembly 180, and a return air vent 190 is provided at the rear of the freezer compartment 110. The return air vent 190 is provided corresponding to the air supply section 162, and the front end of the air supply section 162 is connected to the bottom end of the return air section 161, the rear end of the air supply section 162 is connected to the return air vent 190, and the return air vent 190 is connected to the evaporator chamber 150.

[0119] It is understandable that the chilled airflow from the cooling duct 120 (first cooling channel 121 and second cooling channel 122) can be returned to the evaporator chamber 150 through the air supply section 162 and the return air port 190.

[0120] Furthermore, since the air supply section 162 is located below the freezer drawer 200, the freezing airflow in the air supply section 162 can continue to contact the inflated bottom plate 220, so that the freezing airflow in the air supply section 162 can continue to exchange heat with the inflated bottom plate 220, thereby further ensuring the refrigerator's quick-freezing effect on food.

[0121] In this embodiment, a return air baffle is provided in the freezer chamber 170 and the freezer compartment 110. An air supply section of a return air duct 160 is formed between the return air baffle and the left and / or right side walls of the freezer chamber 170 and the freezer compartment 110. A return air inlet 190 is opened on the return air baffle, and the top end of the air supply section connects to the return air inlet 190, while the bottom end of the air supply section connects to the evaporator chamber 150. This allows for communication between the return air inlet 190 and the evaporator chamber 150.

[0122] Reference Figure 8 In the second embodiment of the evaporator chamber 150 of this example, the front end of the evaporator baffle 600 is provided with a return air port 190 that connects to the evaporator chamber 150, and the bottom end of the return air section 161 is connected to the return air port 190. Therefore, the chilled airflow flowing out from the cooling duct 120 (first cooling channel 121 and second cooling channel 122) can flow directly downwards through the return air port 190 and return to the evaporator chamber 150.

[0123] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
