[0042] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0043] Reference is made below to Figures 1-11 A refrigeration device according to embodiments of the present application is described.

[0044] Reference is made below to Figure 1 The refrigeration device 1000 provided by embodiments of the present application includes a cabinet 100, a door body, and an air duct module 500.

[0045] The refrigeration device 1000 provided by embodiments of the present application can be a side cabinet, a refrigerator, a freezer, or a wine cabinet, etc., and is not specifically limited.

[0046] The cabinet 100 is provided with a refrigeration cavity 120; the air duct module 500 is installed in the cabinet 100, and the air duct module 500 includes a shell, an evaporator 530, and a fan 520. The shell is provided with a cavity, and the evaporator 530 and the fan 520 are arranged in the cavity.

[0047] The cabinet 100 includes an outer shell, and the outer shell is provided with an inner container 110. A heat preservation layer is arranged between the outer shell and the inner container 110. The outer shell can be made of metal (such as steel plate), and the surface is treated by paint spraying to prevent rust and has a certain aesthetic appearance. The heat preservation layer is located between the inner side of the outer shell and the inner container 110, can be polyurethane foam, has good heat insulation performance, can effectively prevent heat exchange between the inside and the outside, and keep the internal temperature stable. The inner container 110 is the part directly contacting the stored objects, and generally can be made of ABS plastic or stainless steel material, requires non-toxic and easy to clean, and the inside of the inner container 110 forms a refrigeration cavity 120 for accommodating the stored objects.

[0048] The door body also includes a three-layer structure of an outer shell, a heat preservation material, and an inner lining, to ensure good sealing performance and heat preservation effect. The door body can be connected with the cabinet 100 through a hinge structure, allowing the door to open and close freely. The door body can be a single door, or a double door, and the single door can also have the function of adjusting the opening direction left and right. A sealing strip can be installed at the edge of the door body, which is tightly attached to the cabinet 100, plays a role in preventing cold air leakage, and cooperates with the cabinet 100 to seal the refrigeration cavity 120.

[0049] The refrigeration cavity 120 can include a refrigeration chamber and a freezing chamber, or only one of the two, and the different chambers have different temperatures and different functions. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device arranged in or outside the cabinet 100.

[0050] The air duct module 500 is installed in the cabinet 100, wherein the air duct module 500 can be installed in the refrigeration cavity 120 or outside the refrigeration cavity 120, specifically, the air duct module 500 can be installed on the inner side of the inner container 110 to directly send air into the refrigeration cavity 120 through the air outlet on the air duct module 500, or the air duct module 500 can be installed on the outer side of the inner container 110 to send air into the refrigeration cavity 120 through the opening on the inner container 110.

[0051] Referring to Figure 2 and Figure 3 , the air duct module 500 includes a shell, an evaporator 530 and a fan 520, the shell can be provided with a cavity for accommodating the fan 520 and the evaporator 530, and the internal space of the cavity can also constitute part of the air duct of the air duct system for cold air circulation. The shell can be made of metal material to have good mechanical strength and corrosion resistance, or can be made of composite material to have good corrosion resistance, light weight and good thermal insulation, which not only reduces the weight of the entire air duct module 500, but also improves the heat preservation effect and reduces energy consumption. The fan 520 is used to drive the circulation of cold air in the refrigeration cavity 120 and the shell to improve the refrigeration efficiency, and the evaporator 530 is used to absorb heat to achieve the refrigeration effect. The fan 520 and the evaporator 530 can be fixed in the shell through a support to ensure their stability and reliability.

[0052] Referring to Figure 1 According to some embodiments of the present application, the refrigeration cavity 120 can include a first refrigeration cavity 120a and a second refrigeration cavity 120b distributed along the height direction, and the first refrigeration cavity 120a is arranged on the upper side of the second refrigeration cavity 120b.

[0053] Taking the refrigeration equipment 1000 as a standing side table as an example, the refrigeration cavity 120 can include a first refrigeration cavity 120a arranged on the upper side and a second refrigeration cavity 120b arranged on the lower side, and by arranging the first refrigeration cavity 120a and the second refrigeration cavity 120b, multiple temperature storage partitions can be achieved. According to the conventional design of the refrigeration equipment 1000, the first refrigeration cavity 120a can be a refrigeration chamber with a relatively high temperature, used for storing storage objects that need to be refrigerated and fresh, and the second refrigeration cavity 120b can be a freezer with a relatively low temperature, used for storing storage objects that need to be frozen for a long time. It can be understood that in the case of multiple refrigeration cavities 120, the inner container 110 is provided with multiple.

[0054] The air duct module 500 can be arranged in the second refrigeration cavity 120b.

[0055] By setting the air duct module 500 in the second refrigeration cavity 120b, the cold air circulation path between the air duct module 500 and the second refrigeration cavity 120b is shorter, and the cold air circulation path between the air duct module 500 and the first refrigeration cavity 120a is longer, so that the temperature of the second refrigeration cavity 120b is lower than that of the first refrigeration cavity 120a, facilitating temperature differentiation.

[0056] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the air supply shell 410 is arranged on one side of the shell, and the air supply shell 410 is provided with an air supply passage 411 connected with the air outlet of the fan 520. The air supply passage 411 is in communication with the refrigeration cavity 120, and the air supply passage 411 is provided with an air door 412 arranged at an angle with the horizontal direction.

[0057] The air supply shell 410 is connected with the shell, so that the air outlet of the fan 520 can be connected with the air supply passage 411 in the air supply shell 410. By arranging the air supply shell 410, the cold air blown by the fan 520 can be delivered into the corresponding refrigeration cavity 120 through the air supply passage 411.

[0058] Taking the air duct module 500 arranged in the second refrigeration cavity 120b as an example, the air supply shell 410 can be arranged between the first refrigeration cavity 120a and the second refrigeration cavity 120b, and the air supply passage 411 is in communication with the first refrigeration cavity 120a, so that the fan 520 can output cold air into the first refrigeration cavity 120a through the air supply passage 411.

[0059] The air supply passage 411 is provided with an air door 412, which can be used to open or close the air supply passage 411 to adjust the air volume delivered into the refrigeration cavity 120, thereby realizing temperature adjustment of the corresponding refrigeration cavity 120. For example, when the temperature of the refrigeration cavity 120 does not reach the set temperature, the air door 412 is controlled to open to deliver cold air into the refrigeration cavity 120 to reduce the temperature of the refrigeration cavity 120; when the temperature of the refrigeration cavity 120 reaches or exceeds the set requirement, the air door 412 can be closed to stop delivering cold air into the refrigeration cavity 120. In some examples, the opening degree of the air door 412 can also be controlled to adjust the flow area of the air supply passage 411, thereby changing the air volume of the cold air delivered into the corresponding refrigeration cavity 120, and realizing precise temperature control.

[0060] For example, the air supply shell 410 is arranged between the air duct module 500 and the first refrigeration cavity 120a, the first refrigeration cavity 120a is a refrigeration chamber, and the temperature is relatively high compared with the temperature in the air duct module 500. Therefore, the air door 412 or the inner wall of the air supply passage 411 has a risk of producing condensate water. After the condensate water is produced, if the condensate water is accumulated at the position of the door body, there is a high probability that the air door 412 is frosted at the position of the air door 412 under the action of cold air of the air duct module 500 below zero degree, which may affect the air supply efficiency, or the air door 412 is frozen and cannot be normally opened and closed, thereby causing damage to the air door 412 and affecting the refrigeration effect.

[0061] The air door 412 is arranged at an angle with the horizontal direction, that is, the door body of the air door 412 is arranged at an angle with the horizontal direction. When the condensate water produced on the air door 412 body or the condensate water at other positions falls on the air door 412, the condensate water can flow away along the inclined direction of the air door 412 under the action of gravity, so that the condensate water is discharged before it is condensed into frost, thereby reducing the risk of frosting at the air door 412, improving the service life and use stability of the air door 412, and further improving the overall refrigeration effect.

[0062] According to the refrigeration equipment 1000 provided in the embodiments of the present application, the air door 412 is arranged at an angle with the horizontal direction, so that the condensate water accumulated on the air door 412 can quickly flow away, thereby reducing the risk of frosting at the air door 412, preventing the air door 412 from being normally used due to condensation, increasing the service life of the air door 412, and improving the refrigeration effect.

[0063] Please refer to Figure 6 According to some embodiments of the present application, the air door 412 can be movably arranged between a closed position for closing the air supply passage 411 and an open position for opening the air supply passage 411, and the air door 412 can be arranged at an angle with the horizontal direction in the closed position and the open position.

[0064] In Figure 6 , the air door 412(a) refers to the state that the air door 412 is in the closed position, the air door 412(b) refers to the state that the air door 412 is in the open position, the air door 412 closes the air supply passage 411 in the closed position, and the air supply passage 411 stops air supply to the corresponding refrigeration cavity 120, and the air door 412 opens the air supply passage 411 in the open position, and the air supply passage 411 can supply air to the corresponding refrigeration cavity 120.

[0065] By arranging the air door 412 at an angle with the horizontal direction in the closed position and the open position, the condensate water is not easy to accumulate on the air door 412 whether the air door 412 is in the closed position or the open position, thereby further reducing the risk of frosting of the air door 412 and improving the use stability.

[0066] According to some embodiments of the present application, at least part of the air door 412 is opposite to the impeller 512 of the air blower 520 when the air door 412 is in the closed position to close the air supply passage 411. Figure 6

[0067] It can be understood that, generally, in order to close the air supply passage 411, the air door 412 needs to extend along the cross section of the air supply passage 411 to better close the air supply passage 411, and to reduce the volume of the air door 412. By arranging that at least part of the air door 412 is opposite to the impeller 512 of the air blower 520 when the air door 412 is in the closed position, the air volume generated by the rotation of the impeller 512 of the air blower 520 can be better delivered into the air supply passage 411, reducing the air supply resistance and improving the air supply efficiency.

[0068] According to some embodiments of the present application, one end of the air door 412 is rotatably installed on the inner wall of the air supply passage 411, and the other end of the air door 412 can be arranged to be inclined away from the impeller 512 when the air door 412 is in the closed position. Figure 6

[0069] One end of the air door 412 is rotatably installed on the inner wall of the air supply passage 411, and the air door 412 is switched between the open position and the closed position by means of rotational movement, which is simple to control and occupies small space. When the air door 412 is rotated to the closed position, the air supply passage 411 is closed, and when the air door 412 is rotated to the open position, the air door 412 is close to the inner wall of the air supply passage 411 to open the air supply passage 411.

[0070] It can be understood that the other end of the air door 412, i.e. the free end of the air door 412, has at least part opposite to the impeller 512 when the air door 412 is in the closed position. In order to reduce the resistance of the air door 412 to the cold air when the air door 412 is in the open position, the impeller 512 is opposite to the part of the air door 412 close to the free end, so that the air door 412 is dislocated from the air outlet of the air blower 520 after the air door 412 is rotated to the open position, reducing the air outlet resistance.

[0071] ​​When the damper 412 is in the closed position, the damper 412 is arranged to tilt from one end to the other end (i.e., the free end) of the damper 412 in a direction away from the impeller 512, thereby increasing the distance between the free end of the damper 412 and the impeller 512. It should be noted that during the operation of the refrigeration device 1000, some condensed water may condense or fall on the impeller 512, and the condensed water on the impeller 512 may be thrown outwards by the impeller 512 during the operation of the impeller 512. By arranging the free end of the damper 412 to be away from the impeller 512, the probability of the water on the impeller 512 being thrown onto the damper 412 is reduced, thereby reducing the probability of the damper 412 frosting and improving the overall stability and refrigeration effect.

[0072] Referring to Figure 6 According to some embodiments of the present application, the damper 412 can be arranged on the upper side of the impeller 512, and one end of the damper 412 can rotate about a horizontal axis.

[0073] With the air duct module 500 arranged in the second refrigeration cavity 120b, and the air supply shell 410 arranged on the upper side of the second refrigeration cavity 120b, the air supply shell 410 is connected to the upper end of the shell, so that the air supply passage 411 is located on the upper side of the fan 520, and the damper 412 is also located on the upper side of the impeller 512. The air supply passage 411 extends in the height direction to connect the first refrigeration cavity 120a and the air outlet of the fan 520. By arranging one end of the damper 412 to rotate about a horizontal axis, the damper 412 can better close the air supply passage 411, and can better avoid obstacles when opened.

[0074] When one end of the damper 412 rotates about the axis, the other end of the damper 412 moves in the height direction. Specifically, because the air supply direction is upward when the air supply passage 411 is on the upper side of the fan 520, the other end of the damper 412 is in the closed position when it is rotated upward to the highest point, and the closing effect is better. When the other end of the damper 412 is rotated to the lowest point, it is in the open position, does not occupy the air supply passage 411 on the upper side, reduces the air supply resistance, and improves the air supply efficiency.

[0075] Referring to Figure 6 According to some embodiments of the present application, one end of the damper 412 can be rotationally connected to the air supply passage 411. When the damper 412 is in the closed position, the other end of the damper 412 can be located on the upper side of the one end of the damper 412 rotationally connected to the air supply passage 411.

[0076] In the case that the damper 412 is located at the closed position, the other end of the damper 412 away from the rotating end abuts against the wall surface of the air supply channel 411 to seal the air supply channel 411, by arranging the other end of the damper 412 to be located at the upper side of the one end of the damper 412 which is rotationally connected, to avoid the condensate water from gathering at the free end of the damper 412, to reduce the risk that the free end of the damper 412 is fixed due to frosting and cannot be opened, and the free end of the damper 412 abuts against the wall surface of the air supply channel 411 under the driving force of the cold air and the driving force of the driving assembly 413, so that the condensate water is not easy to flow out through the free end of the damper 412; and the rotating section of the damper 412 needs to rotate, so that there is a certain activity gap between the rotating end of the damper 412 and the adjacent structure, and the condensate water can flow out through the activity gap when flowing to the rotating end under the action of gravity, so that the condensate water is not easy to gather at the rotating end, thereby reducing the probability of frosting at each position of the damper 412, improving the use stability of the damper 412, and further improving the refrigeration effect.

[0077] Please refer to Figure 4 , Figure 7 and Figure 8 , according to some embodiments of the present application, the first refrigeration cavity 120a includes two chambers spaced from each other, the air supply channel 411 is provided with two air supply channels corresponding to the two chambers respectively, and the two air supply channels 411 are each provided with a damper 412.

[0078] By separating the first refrigeration cavity 120a into two chambers, the classified storage of the stored objects is facilitated, and the temperature difference control of different chambers can also be achieved. By arranging two air supply channels 411 corresponding to two chambers respectively, the cold air output by the fan 520 can be output into the two chambers through the two air supply channels 411 respectively, and the two air supply channels 411 can each be provided with a damper 412 to control the opening and closing of the two air supply channels 411 respectively.

[0079] The two dampers 412 can be synchronously opened and closed, or can be separately actuated to achieve the same temperature control of the two chambers, or can achieve different temperatures of the two chambers.

[0080] Please refer to Figure 8 and Figure 9 , according to some embodiments of the present application, the two air supply channels 411 can be arranged along the depth direction of the refrigeration cavity 120, and the two dampers 412 are inclined relative to the width direction of the refrigeration cavity 120.

[0081] The two air supply channels 411 are arranged along the depth direction of the refrigeration cavity 120, which reduces the occupation in the width direction of the entire refrigeration cavity 120 in the case that the thickness of the entire refrigeration device 1000 is thin, and improves the space utilization rate of the refrigeration cavity 120.

[0082] In the case that the two air supply channels 411 are arranged along the depth direction of the refrigeration cavity 120, in order to ensure that the flow area of the air supply channel 411 is sufficient, the cross section of the air supply channel 411 also extends along the depth direction of the refrigeration cavity 120, so that the size of the air supply channel 411 in the width direction of the refrigeration cavity 120 is small. By arranging the two dampers 412 to be inclined with respect to the width direction and the height direction of the refrigeration cavity 120, the path of the condensed water flowing along the inclined surface on the surface of the damper 412 is shortened, the condensed water discharge efficiency is improved, the risk of frosting is reduced, and the use stability is improved.

[0083] Referring to Figure 8 , Figure 9 and Figure 10 According to some embodiments of the present application, the air supply shell 410 can be provided with a driving assembly 413, which can be arranged between the two air supply channels 411 and is in power coupling connection with the two dampers 412.

[0084] By integrating the driving assembly 413 in the air supply shell 410 and arranging the driving assembly 413 between the two air supply channels 411, one driving assembly 413 can drive two dampers 412 to move, thereby reducing the space occupied by the entire device and improving the space utilization. The driving assembly 413 can drive two dampers 412 to move synchronously, or can drive a single damper 412 to move respectively. Specifically, a gear set or other transmission assembly can be arranged in the driving assembly 413 to realize the separate movement of the two dampers 412.

[0085] Referring to Figure 6 According to some embodiments of the present application, the surface of the damper 412 can be provided with a heat preservation member. For example, the heat preservation member can be arranged on the side of the damper 412 away from the fan 520, so as to isolate the cold in the air duct module 500 from being transferred to the other side of the damper 412, thereby reducing the risk of condensation on the surface of the damper 412, and further reducing the risk of frosting.

[0086] Referring to Figure 9 and Figure 11 According to some embodiments of the present application, the refrigeration device 1000 can further include an air return shell 420 arranged on the side of the shell provided with the air supply shell 410. The air return shell 420 is provided with an air return channel 421 in communication with the cavity, and the air supply shell 410 and the air return shell 420 are integrally formed.

[0087] The air return shell 420 is arranged on one side of the shell body provided with the air supply shell 410, and the air return channel 421 is arranged in the air return shell 420, so that the gas in the refrigeration cavity 120 can return to the cavity through the air return channel 421, and the circulation of cold air between the refrigeration cavity 120 and the cavity is realized. The air supply shell 410 and the air return shell 420 are integrally formed, which simplifies the assembly of the air supply shell 410 and the air return shell 420. The air supply and return integrated shell 400 composed of the air supply shell 410 and the air return shell 420 is installed on one side of the refrigeration cavity 120 and connected with the shell body, which reduces the number of parts and greatly improves the assembly and production efficiency.

[0088] Taking the example that the air supply and return integrated shell 400 is installed between the first refrigeration cavity 120a and the second refrigeration cavity 120b, the air supply and return integrated shell 400 can be provided with sealing pads at both ends in the height direction to seal the gap between the air supply and return integrated shell 400 and the inner container 110 on the upper and lower sides, thereby reducing the probability of cold air leakage and improving the refrigeration effect.

[0089] Please refer to Figure 9 , Figure 10 and Figure 11 According to some embodiments of the present application, the air supply and return integrated shell 400 can be provided with a mounting assembly 414, the mounting assembly 414 can be provided with two air supply channels 411, and the mounting assembly 414 can be mounted with two air doors 412 movably arranged in the two air supply channels 411 and a driving assembly 413 power-coupled with the two air doors 412.

[0090] The mounting assembly 414 is arranged to facilitate the arrangement of the air door 412 in the air supply and return integrated shell 400. Since the air supply and return integrated shell 400 is provided with a plurality of air supply channels 411, a plurality of air doors 412 are arranged, and the plurality of air doors 412 and the driving assembly 413 are installed in the integrally formed air supply and return integrated shell 400. The mounting assembly 414 is arranged, the two air supply channels 411, the air door 412 and the driving assembly 413 are arranged on the mounting assembly 414, and the mounting assembly 414 is connected with the air supply shell 410, so that the arrangement of the air supply channel 411 and the installation of the air door 412 are completed. The assembly is simple and efficient, which reduces the development cost and improves the production efficiency.

[0091] Please refer to Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present application, the refrigeration device 1000 can include a partition assembly 300 arranged in the first refrigeration cavity 120a and arranged along the depth direction of the first refrigeration cavity 120a. The partition assembly 300 is provided with an air supply pipe 311 in communication with the first refrigeration cavity 120a and the air supply channel 411, respectively.

[0092] The partition assembly 300 is provided with a supply air pipe 311 in communication with the first refrigeration cavity 120a, and the supply air pipe 311 can supply cold air to the first refrigeration cavity 120a. By arranging the partition assembly 300 along the depth direction of the first refrigeration cavity 120a, the partition assembly 300 and the supply air pipe 311 arranged in the partition assembly 300 are arranged on the side of the first refrigeration cavity 120a in the width direction, thereby reducing the occupation of the partition assembly 300 in the depth direction of the first refrigeration cavity 120a. In the case that the depth of the refrigeration cavity 120 is the same, compared with the conventional refrigeration equipment 1000 in which the supply air pipe 311 is arranged on one side of the refrigeration cavity 120 in the depth direction, the overall thickness of the refrigeration equipment 1000 can be thinner, and the aesthetic and practicality can be improved.

[0093] The supply and return air integrated shell 400 is arranged on one side of the first refrigeration cavity 120a and connected with the partition assembly 300, so that the supply air passage 411 of the supply and return air integrated shell 400 is connected with the supply air pipe 311, and cold air is supplied to the supply air pipe 311 through the supply air passage 411, and then the cold air is supplied to the first refrigeration cavity 120a through the supply air pipe 311, so as to realize refrigeration of the first refrigeration cavity 120a. The return air passage 421 is in communication with the refrigeration cavity 120, and the cold air in the refrigeration cavity 120 can be recovered to the evaporator 530 through the return air passage 421 for refrigeration, and then the cold air is supplied out through the supply air passage 411, so as to form a circulation of the cold air in the refrigeration equipment 1000.

[0094] Please refer to Figure 3 According to some embodiments of the present application, the air duct module 500 can be provided with a supply air cavity 510 and a return air pipe 540, the supply air cavity 510 can be provided with a fan 520 and an evaporator 530, and the two ends of the supply air passage 411 in the height direction are connected with the supply air pipe 311 and the supply air cavity 510 respectively, and the two ends of the return air passage 421 are connected with the return air pipe 540 and the first refrigeration cavity 120a respectively.

[0095] The fan 520 is used to drive the circulation of cold air in the refrigeration cavity 120 and the shell, so as to improve the refrigeration efficiency, and the evaporator 530 is used to absorb heat to achieve refrigeration effect. The fan 520 and the evaporator 530 can be fixed in the supply air cavity 510 through a support, so as to ensure the stability and reliability.

[0096] The upper end of the supply air passage 411 is in communication with the supply air pipe 311, and the lower end is in communication with the supply air cavity 510, so that when the fan 520 in the supply air cavity 510 works, the cold air in the supply air cavity 510 can be supplied to the supply air passage 411. The upper end of the return air passage 421 is in communication with the first refrigeration cavity 120a, and the lower end is in communication with the return air pipe 540, so that the hot air in the first refrigeration cavity 120a can enter the return air pipe 540 through the return air passage 421, and then the return air pipe 540 is connected to the supply air cavity 510.

[0097] The fan 520 is installed at the upper end of the air supply cavity 510, so that the fan 520 is arranged close to the air supply and return integrated shell 400, and the upper air outlet of the fan 520 is directly connected with the air supply channel 411, so as to shorten the air outlet path and improve the air outlet efficiency.

[0098] Referring to Figures 1-4 According to some embodiments of the present application, the partition assembly 300 can be arranged at the middle of the first refrigeration cavity 120a in the width direction to divide the first refrigeration cavity 120a into two chambers, and the air duct module 500 can be arranged at the middle of the second refrigeration cavity 120b in the width direction.

[0099] By arranging the partition assembly 300 at the middle of the first refrigeration cavity 120a in the width direction and arranging the air duct module 500 at the middle of the second refrigeration cavity 120b in the width direction, the refrigeration equipment 1000 is a vertical middle system, and the air duct system of the refrigeration equipment 1000 is arranged at the middle of the refrigeration equipment 1000, and the first refrigeration cavity 120a and the second refrigeration cavity 120b are both divided into two chambers.

[0100] From the perspective of temperature control, different chambers can have different temperatures to meet the storage needs of different types of food, and two chambers can have respective door bodies corresponding thereto, and the temperature of each chamber can be independently controlled to reduce the influence on the temperature of other chambers when the door is opened, thereby maintaining a stable storage environment. Each chamber can independently control the temperature to reduce unnecessary waste of cold energy and improve overall energy efficiency. In addition, the small chamber is easier to cool quickly than the large chamber, which reduces the working time and energy consumption of the compressor.

[0101] From the perspective of space utilization, the partition assembly 300 can be adjusted according to actual needs, so that users can flexibly allocate storage space according to the size and quantity of food, and different types of storage objects can be stored separately to avoid cross-infection and maintain the freshness and hygiene of the storage objects. Users can also quickly find the required objects according to the type of storage objects, improve the convenience of taking objects, reduce the door opening time, and further reduce the loss of cold energy. Different chambers can effectively isolate the odors between foods and keep the air inside the refrigerator fresh.

[0102] Referring to Figure 4 According to some embodiments of the present application, at least one air return opening 313 in communication with the air return channel 421 can be arranged in the refrigeration cavity 120, and the at least one air return opening 313 is arranged on the side of the refrigeration cavity 120 close to the door body.

[0103] Here the refrigeration cavity 120 refers to the first refrigeration cavity 120a, and the door body cover is arranged at the opening of the first refrigeration cavity 120a to seal the first refrigeration cavity 120a in cooperation with the box body 100. The return air port 313 is arranged in communication with the return air channel 421 to supply return air for the first refrigeration cavity 120a. By arranging the return air port 313 on the side of the first refrigeration cavity 120a close to the door body, that is, the return air channel 421 and the return air port 313 are both located on the side close to the opening of the first refrigeration cavity 120a.

[0104] By arranging the return air port 313 on the side close to the door body, when the door is opened, the warm air outside can enter the inside of the first refrigeration cavity 120a. The side of the return air channel 421 close to the door body can quickly suck in and cool the warm air, reduce temperature fluctuations, and maintain the stability of the temperature in the cavity. Since the return air channel 421 can quickly exhaust the incoming warm air, the working time of the compressor is shortened, thereby reducing energy consumption and improving energy efficiency. The side of the return air channel 421 close to the door can more effectively exhaust the moisture at the door gap, reduce the formation of condensed water, and keep the inside of the refrigerator dry. In addition, the position of the return air port 313 will not affect the user to take and place food, because most users are used to taking food from the side close to the door. The air supply channel 411 is arranged on the side away from the door body to avoid the cold air directly blowing on the user when the user opens the door to take food. Such a design is more humanized and improves the user experience.

[0105] In addition, the problem of multiple online assembly processes of refrigeration components and air ducts in existing products is solved, the assembly difficulty is reduced, the labor cost is reduced, and the assembly efficiency is improved. In addition, the idle space in the refrigerator is fully utilized, thereby increasing the internal volume of the first refrigeration cavity 120a and the second refrigeration cavity 120b, and realizing large-space storage of the refrigeration equipment 1000.

[0106] Please refer to Figure 4 and Figure 9 According to some embodiments of the present application, the wall surface of the chamber close to the air supply and return integrated shell 400 can be provided with a return air port 313, and the return air channel 421 can have two air inlet ends 4211 connected with the return air ports 313 of the two chambers respectively.

[0107] First of all, it should be pointed out that, Figure 4 The inner liner of the first refrigeration cavity 120a is not shown in Figure 1 , and the position of the return air port 313 can be determined by referring to the inner liner 110 in

[0108] The chamber is close to the wall surface of the air supply and return integrated shell 400, that is, the lower bottom wall of the chamber is provided with the air return opening 313, the air return effect is good, the air return efficiency is high, and the two air return openings 313 are arranged on the two sides of the partition plate assembly 300. By arranging the air return channel 421 to have two air inlet ends 4211 communicated with the air return openings 313 of the two chambers, the hot air of the two chambers can enter the air return channel 421.

[0109] The air return channel 421 can be provided with an air outlet end 4212, so that the air outlet end 4212 of the air return channel 421 is communicated with the air return pipe 540, and the two air inlet ends 4211 of the air return channel 421 are communicated with the air outlet end 4212, so that the air return channel 421 is Y-shaped, simple in structure and capable of realizing air return of the two chambers at the same time.

[0110] This layout can optimize the air circulation path, so that the cold air can quickly cover every corner of the first refrigeration chamber 120a, improve the refrigeration effect and food preservation performance, and at the same time, this structure also helps to reduce the loss of cold air and improve the energy efficiency of the refrigeration equipment 1000.

[0111] According to some embodiments of the present application, the thickness W of the refrigeration equipment 1000 in the depth direction of the first refrigeration chamber 120a can satisfy: 450mm≤W≤600mm.

[0112] The thickness of the refrigeration equipment 1000 is thin and good in appearance, which can better adapt to the indoor decoration of the user and improve the product quality. The thickness W of the refrigeration equipment 1000 in the depth direction of the first refrigeration chamber 120a is in the range of [450mm, 600mm], and exemplarily, W can take values of 450mm, 500mm, 550mm, 600mm or other values between 450mm and 600mm, and the specific values are not limited.

[0113] According to some embodiments of the present application, the thickness S of the door body can satisfy: 25mm≤S≤40mm.

[0114] The thickness of the door body of the refrigeration equipment 1000 is thin, light and convenient to open, and reduces the influence on the thickness of the entire refrigeration equipment 1000, so that the refrigeration equipment 1000 can be made thinner to better adapt to the indoor decoration of the user and improve the product quality. The thickness S of the door body is in the range of [25mm, 50mm], and exemplarily, S can take values of 25mm, 30mm, 35mm, 40mm or other values between 25mm and 40mm, and the specific values are not limited.
