[0048] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar numerals or characters represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0049] Reference is made below to Figures 1-17 A refrigeration device according to an embodiment of the present application is described.

[0050] Reference is made below to Figure 1 The refrigeration device 1000 provided by the embodiment of the present application includes a cabinet 100, a door body (not shown in the figure), and a partition assembly 300.

[0051] The refrigeration device 1000 provided by the embodiment of the present application can be a side cabinet, a refrigerator, a freezer, or a wine cabinet, etc., and is not specifically limited.

[0052] The cabinet 100 is provided with a first refrigeration cavity 120a, and the partition assembly 300 is arranged in the first refrigeration cavity 120a and arranged along the depth direction of the first refrigeration cavity 120a, and divides the first refrigeration cavity 120a into two chambers.

[0053] 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, and can be polyurethane foam, which has good heat insulation performance and can effectively prevent heat exchange between the inside and the outside, thereby maintaining the internal temperature stable. The inner container 110 is the part directly contacting the stored objects, and is generally made of ABS plastic or stainless steel material, which is required to be non-toxic and easy to clean. The inner container 110 is internally formed with the first refrigeration cavity 120a for accommodating the stored objects.

[0054] The door body also comprises a three-layer structure of an outer shell, thermal insulation material and inner lining, ensuring good sealing and thermal insulation effect. The door body can be connected to the cabinet 100 through a hinge structure, allowing the door to open and close freely. The door 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 tightly fits the cabinet 100 to prevent cold air leakage, and cooperates with the cabinet 100 to seal the first refrigeration cavity 120a.

[0055] The refrigeration cavity 120 can include a refrigeration chamber and a freezing chamber, or only one of the two, with different temperatures and functions. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device arranged inside or outside the cabinet 100.

[0056] The partition assembly 300 extends along the depth direction and is arranged in the middle of the first refrigeration cavity 120a to divide the first refrigeration cavity 120a into two chambers. From the perspective of temperature and humidity control, different chambers can have different temperatures and humidities to meet the storage needs of different types of food, and two chambers can have corresponding doors. The temperature of each chamber can be independently controlled to reduce the impact on the temperature of other chambers when the door is opened, maintaining a stable storage environment. Each chamber can independently control the temperature, reducing unnecessary cold waste and improving overall energy efficiency. Moreover, small chambers are easier to cool quickly than large chambers, reducing compressor operating time and energy consumption.

[0057] From the perspective of space utilization, the partition assembly 300 can be adjusted according to actual needs, allowing users to flexibly allocate storage space according to the size and quantity of food. Different types of storage items can be stored separately to avoid cross-infection and maintain the freshness and hygiene of the stored items. Users can also quickly find the items they need, improving the convenience of taking items, reducing door opening time, and further reducing cold loss. Different chambers can effectively isolate odors between foods, keeping the air inside the refrigerator fresh.

[0058] For example, the partition assembly 300 can also extend along the height direction to divide the first refrigeration cavity 120a into two chambers along the width direction, improving the convenience of use and the stability of the structure.

[0059] Please refer to Figure 2 , Figure 3 and Figure 4 The return air shell 420 is arranged on one side of the first refrigeration cavity 120a and connected to the partition assembly 300. The return air shell 420 has a return air passage 421 communicating with the two chambers.

[0060] The return air shell 420 is arranged at one side of the first refrigeration cavity 120a, specifically, the return air shell 420 is arranged outside the inner container 110 to recover the hot air circulated in the first refrigeration cavity 120a and introduce the hot air to the evaporator 530 to circulate the cold air in the refrigeration equipment 1000. The return air shell 420 is connected with the partition assembly 300, that is, the return air shell 420 is also arranged at the middle of the first refrigeration cavity 120a in the width direction, so that the return air shell 420 is close to both cavities, and the return air passage 421 in the return air shell 420 can be in communication with both cavities at the same time, both cavities can return air through the return air passage 421 of one return air shell 420, and one return air structure can simplify the design of the interior of the refrigeration equipment 1000, reduce the number of required pipelines and components, save space, improve space utilization and assembly efficiency.

[0061] In addition, the single return air structure can increase the size of the return air passage 421 due to the saved space occupied by the component structure, reduce the air flow resistance, improve the cold air circulation efficiency, thereby reducing the working time and energy consumption of the compressor. The noise of air flow can also be reduced, and the quiet experience of the user when using the refrigerator can be improved. The potential failure point is reduced, and the reliability and stability of the system are improved. When a single return air structure fails, it is easier to locate and repair, and the maintenance time and cost are reduced.

[0062] According to the refrigeration equipment 1000 provided by the embodiments of the present application, the return air shell 420 is arranged and the return air passage 421 simultaneously returns air to both cavities, which simplifies the return air structure, improves space utilization, and facilitates assembly and reduces production and maintenance costs.

[0063] Please refer to Figures 5 to 9 According to some embodiments of the present application, the door body can be arranged at the opening of the first refrigeration cavity 120a, and the return air shell 420 can be located close to the door body.

[0064] The opening of the first refrigeration cavity 120a can be used by the user to store objects. One first refrigeration cavity 120a can be provided with one door body, so that one door body can simultaneously seal two cavities, or one first refrigeration cavity 120a can be provided with two door bodies, and the two door bodies correspond to two cavities, respectively. The door body of a single cavity can be opened and closed individually, which improves the use convenience and reduces the energy consumption.

[0065] The return air shell 420 is arranged on the side close to the door body, that is, the return air passage 421 is arranged on the side close to the door body. When the door is opened, the warm air outside enters the first first refrigeration cavity 120a. The side of the return air passage 421 close to the door body can quickly suck in and cool the warm air, reduce temperature fluctuation, and maintain the stability of the temperature in the cavity. Because the return air passage 421 can quickly exhaust the entering warm air, the compressor working time is shortened, thereby reducing energy consumption and improving energy efficiency. The side of the return air passage 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 does not affect the user to take and place food, because most users are used to taking things from the side close to the door. The air supply passage 411 is arranged on the side away from the door body, avoiding the cold air directly blowing on the user when the user opens the door to take things. Such design is more humanized and improves the user experience.

[0066] Please refer to Figures 3 to 9 , especially Figure 3 and Figure 4 According to some embodiments of the present application, the partition assembly 300 includes two partitions 310 corresponding to two cavities, both of which are provided with return air ports 313. A communication cavity 312 is arranged between the two partitions 310 and communicates with the two return air ports 313. The return air passage 421 communicates with the communication cavity 312.

[0067] The two partitions 310 can be arranged at intervals along the distribution direction of the cavities, so as to facilitate the arrangement of thermal insulation materials between the two partitions 310. By arranging thermal insulation materials in the partition assembly 300, the temperature transfer between the two cavities is isolated, and the refrigeration effect is improved.

[0068] The partition 310 can be provided with a return air port 313. The return air port 313 on the partition 310 is used for the return air of the corresponding cavity. A communication cavity 312 is arranged between the two partitions 310 and communicates with the two return air ports 313. Specifically, the two return air ports 313 can be arranged oppositely to reduce the space occupied by the communication cavity 312. The communication cavity 312 can be arranged at one end of the partition assembly 300 close to the return air shell 420, so as to facilitate the communication between the communication cavity 312 and the return air passage 421. The hot air in the two cavities is communicated to the communication cavity 312 through the return air port 313, and then enters the return air passage 421 through the communication cavity 312, thereby realizing the return air of the two cavities.

[0069] The two chambers can return air through the middle partition assembly 300, greatly simplifying the structure inside the refrigeration device 1000, reducing additional pipelines and components, making the internal space more compact, and improving space utilization. Because the air return port 313 is arranged on the partition 310, that is, the air return port 313 is arranged in the height direction, the risk of the article falling into the air return port 313 is reduced, and the use convenience is improved.

[0070] Please refer to Figure 4 , Figure 8 and Figure 9 According to some embodiments of the present application, the partition assembly 300 can be connected with both ends in the height direction of the first refrigeration chamber 120a, and the communication cavity 312 can be located at one end in the height direction of the partition assembly 300.

[0071] The partition assembly 300 is connected with both ends in the height direction of the first refrigeration chamber 120a, and the partition assembly 300 is also connected with the back wall of the first refrigeration chamber 120a in the depth direction, which can provide better structural support, increase the stability of the partition assembly 300, and reduce deformation or displacement caused by vibration or external force.

[0072] The communication cavity 312 is arranged at one end in the height direction of the partition assembly 300 to provide a better gas circulation path and improve the effect of cold air circulation refrigeration. At the same time, arranging the communication cavity 312 at the end can reduce the space occupied by the communication cavity 312 and ensure the heat insulation performance of the partition assembly 300. Specifically, because of the principle of cold air sinking, the communication cavity 312 can be arranged at the lower end of the partition assembly 300, and the air return shell 420 is also arranged at the lower end of the first refrigeration chamber 120a to be connected with the communication cavity 312.

[0073] The projection of the air return channel 421 in the height direction can be located in the communication cavity 312, that is, the projection of the air return channel 421 in the height direction is located in the partition assembly 300, so as to control the size of the air return channel 421 and the air return shell 420, reduce the volume of parts, improve space utilization, and also reduce production cost and improve economic benefit.

[0074] Please refer to Figure 4 According to some embodiments of the present application, the communication cavity 312 can be provided with a baffle 315, and the baffle 315 can be arranged between the two air return ports 313.

[0075] The baffle 315 can extend in the height direction and the depth direction of the refrigeration cavity 120, and the baffle 315 is located at the middle of the baffle 315 assembly in the thickness direction, so that the baffle 315 separates the two return air inlets 313. The baffle 315 can prevent cold air or warm air from directly flowing between the two return air inlets 313, avoid air flow short circuit phenomenon, ensure that the cold air or warm air can be more evenly distributed in each cavity, the baffle 315 can guide the air flow to flow along a predetermined path, ensure that each cavity can obtain sufficient cold air or warm air, improve the cold air circulation efficiency, help to more accurately control the temperature of each cavity, and improve the accuracy of temperature control. The baffle 315 can also reduce the turbulence of the air flow in the communication cavity 312, reduce the noise generated when the air flow passes through, and improve the quiet experience of the user when using the refrigerator.

[0076] Please refer to Figures 6 to 9 According to some embodiments of the present application, the partition assembly 300 is provided with two air supply pipes 311 for supplying air to the two cavities respectively; the refrigeration equipment 1000 can further include an air supply shell 410, which is connected with the partition assembly 300 and is located on one side of the return air shell 420 in the depth direction of the first refrigeration cavity 120a, and the air supply shell 410 is provided with two air supply channels 411 corresponding to the two air supply pipes 311.

[0077] By arranging two air supply pipes 311 in the partition assembly 300, the two air supply pipes 311 are used to supply air to the two cavities of the first refrigeration cavity 120a respectively, which facilitates precise air supply to the two cavities. The air supply shell 410 is provided with two air supply channels 411 corresponding to the two air supply pipes 311, and air is supplied to the corresponding air supply pipe 311 through the corresponding air supply channel 411, which improves the temperature control accuracy of the corresponding cavity.

[0078] Among them, the air supply shell 410 is located on one side of the return air shell 420 in the depth direction of the first refrigeration cavity 120a, for example, the air supply shell 410 is located on the side away from the door body of the return air shell 420. By arranging the air supply shell 410 and the return air shell 420 along the depth direction of the first refrigeration cavity 120a, the air supply shell 410 and the return air shell 420 are connected with the partition assembly 300, and the occupation of the internal space of the refrigeration equipment 1000 is further reduced, and the space utilization rate is improved.

[0079] Please refer to Figure 6 and Figure 9 In some embodiments, the two air supply channels 411 and the return air channel 421 can be arranged along the depth direction of the first refrigeration cavity 120a, and the two air supply pipes 311 are also arranged along the depth direction of the first refrigeration cavity 120a. To reduce the occupation of the air supply and return integrated shell 400 and the partition assembly 300 in the width direction of the refrigeration equipment 1000, improve the space utilization rate, and facilitate the corresponding connection of the air supply channel 411 and the air supply pipe 311.

[0080] Referring to Figure 10 and Figure 11 According to some embodiments of the present application, the air supply shell 410 can be provided with a mounting assembly 414, the mounting assembly 414 can be provided with two air supply passages 411, the mounting assembly 414 can be mounted with two air doors 412 movably arranged in the two air supply passages 411 and a driving assembly 413 power-coupled with the two air doors 412.

[0081] By providing the mounting assembly 414, the air door 412 can be arranged in the air supply shell 410. Since the air supply shell 410 is provided with multiple air supply passages 411, multiple air doors 412 are provided, and the multiple air doors 412 and the driving assembly 413 are difficult to install in the integrally formed air supply shell 410. By providing the mounting assembly 414, the two air supply passages 411, the air door 412 and the driving assembly 413 are arranged on the mounting assembly 414, and then the mounting assembly 414 is connected with the air supply shell 410, so that the arrangement of the air supply passage 411 and the installation of the air door 412 can be completed, which is simple and efficient, reduces development cost and improves production efficiency.

[0082] Referring to Figure 7 , Figure 8 and Figure 9 According to some embodiments of the present application, at least one of the two partitions 310 includes an access plate 314, the access plate 314 is arranged at one end of the partition assembly 300 connected with the return air shell 420, and the return air port 313 is arranged on the access plate 314.

[0083] At least one of the two partitions 310 can include an access plate 314 and a plate body, the plate body is fixedly connected with the inner container 110 of the cabinet 100, and the access plate 314 is detachably mounted on the plate body. The access plate 314 is arranged at one end of the partition assembly 300 connected with the return air shell 420, that is, one end of the partition assembly 300 connected with the air supply shell 410. By detaching the access plate 314, the return air shell 420, the air supply shell 410, the air door 412 and the driving assembly 413 in the air supply shell 410 can be maintained and repaired, the maintenance efficiency is improved, and the maintenance cost is reduced.

[0084] The return air port 313 of the partition 310 on the side provided with the access plate 314 can be arranged on the access plate 314, so that after the access plate 314 is opened, the communication cavity 312 and the return air shell 420 can be conveniently maintained and repaired.

[0085] The return air port 313 of the refrigeration equipment 1000 of the present application can also have another arrangement, which is as follows:

[0086] Referring to Figure 12 , Figure 13 and Figure 14According to some embodiments of the present application, the chamber is provided with a return air inlet 313 near the wall surface of the return air shell 420, and the return air channel 421 has two air inlet ends 4211 respectively connected to the return air inlets 313 of the two chambers.

[0087] For example, the return air shell 420 is arranged on the lower side of the first refrigeration chamber 120a, and the chamber is provided with a return air inlet 313 near the wall surface of the return air shell 420, i.e. on the lower bottom wall of the chamber. The return air effect is good, the return air efficiency is high, and the two return air inlets 313 are arranged on the two sides of the partition assembly 300. By arranging the return air channel 421 to have two air inlet ends 4211 connected to the return air inlets 313 of the two chambers, the hot air of the two chambers can enter the return air channel 421 through the air inlet ends 4211.

[0088] 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.

[0089] Please refer to Figure 14 and Figure 15 According to some embodiments of the present application, the end of the return air shell 420 away from the first refrigeration chamber 120a can be provided with an air outlet end 4212 of the return air channel 421, and the two air inlet ends 4211 are connected to the air outlet end 4212.

[0090] By arranging one air outlet end 4212 and two air inlet ends 4211, the return air of the two chambers can be uniformly collected at the evaporator 530, simplifying the return air structure and improving the return air efficiency. Specifically, the connection between the air inlet end 4211 and the air outlet end 4212 can be arc-shaped, which reduces the air resistance and improves the return air efficiency.

[0091] Please refer to Figure 14 and Figure 15 According to some embodiments of the present application, the return air channel 421 is arranged at one end in the height direction of the first refrigeration chamber 120a, and the projection of the return air channel 421 in the height direction is at least partially located outside the partition assembly 300.

[0092] The projection of the return air channel 421 in the height direction is at least partially located outside the partition assembly 300, so that the two air inlet ends 4211 of the return air channel 421 can correspond to the bottom walls of the two chambers, respectively, and then be connected to the air inlets in the two chambers.

[0093] Specifically, as Figure 16 and Figure 17As shown, the return air shell 420 extends along the distribution direction of the two chambers, so that the return air shell 420 can correspond to the two chambers, and because the supply air shell 410 extends along the depth direction of the first refrigeration chamber 120a, the projection of the supply-return air integrated shell 400 formed by the supply air shell 410 and the return air shell 420 in the height direction is in a T-shaped arrangement.

[0094] Referring to Figure 10 , Figure 16 and Figure 17 , according to some embodiments of the present application, the supply air shell 410 and the return air shell 420 can be integrally formed as a supply-return air integrated shell 400.

[0095] The supply-return air integrated shell 400 simplifies the structure of the air duct system in the refrigeration device 1000, reduces the space occupation, and reduces the number of components, facilitates assembly, and greatly improves the assembly efficiency and assembly precision.

[0096] Specifically, the upper end of the supply air shell 410 is connected to the upper end of the return air shell 420 as a whole, and the lower end of the supply air shell 410 is connected to the lower end of the return air shell 420 as a whole, so that the upper and lower end faces of the supply-return air integrated shell 400 are relatively flat, facilitating connection with the inner containers 110 on the upper and lower sides, and the partition plate assembly 300 and the air duct module 500 located in the two inner containers 110.

[0097] Referring to Figure 1 , Figure 3 and Figure 5 , according to some embodiments of the present application, the cabinet 100 can also be provided with a second refrigeration chamber 120b distributed along the height direction of the first refrigeration chamber 120a, the air duct module 500 can be provided in the second refrigeration chamber 120b, and the supply-return air integrated shell 400 can be arranged between the first refrigeration chamber 120a and the second refrigeration chamber 120b, and can be connected between the air duct module 500 and the partition plate assembly 300.

[0098] Taking the refrigeration device 1000 as a vertical side table as an example, the refrigeration chamber 120 can include a first refrigeration chamber 120a arranged on the upper side and a second refrigeration chamber 120b arranged on the lower side, and by arranging the first refrigeration chamber 120a and the second refrigeration chamber 120b, a storage partition of multiple temperatures can be achieved. According to the conventional design of the refrigeration device 1000, the first refrigeration chamber 120a can be a refrigeration chamber, the temperature is relatively high, and is used to store storage objects that need to be refrigerated and preserved, and the second refrigeration chamber 120b can be a freezer, the temperature is relatively low, and is used to store storage objects that need to be frozen for a long time. It can be understood that in the case where multiple refrigeration chambers 120 are provided, the inner container 110 corresponds to multiple refrigeration chambers 120 and is provided with multiple.

[0099] The air duct module 500 can recycle hot air and output cold air. The air supply and return integrated shell 400 is arranged between the air duct module 500 and the partition assembly 300, so that the cold air output by the air duct module 500 can enter the air supply pipe 311 through the air supply channel 411 and then be transported into the first refrigeration cavity 120a. The air return channel 421 can be in communication with the air duct module 500, so as to recycle the hot air in the first refrigeration cavity 120a into the air duct module 500 through the air return channel 421.

[0100] It should be noted that the air duct module 500 also extends in the depth direction of the second refrigeration cavity 120b, so that the air duct module 500, the air supply and return integrated shell 400 and the partition assembly 300 are vertically opposite in the height direction, thereby reducing the influence on the thickness of the refrigeration equipment 1000 and the effective volume of the first refrigeration cavity 120a and the second refrigeration cavity 120b, and improving the overall refrigeration effect and space utilization.

The two ends of the air return channel 421 are in communication with the air return pipe 540 and the first refrigeration cavity 120a respectively.

[0102] The fan 520 is used to drive the circulation of cold air in the refrigeration cavity 120 and the shell, thereby improving the refrigeration efficiency. 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 air supply cavity 510 by a support, so as to ensure the stability and reliability thereof.

[0103] The upper end of the air supply channel 411 is in communication with the air supply pipe 311, and the lower end is in communication with the air supply cavity 510. When the fan 520 in the air supply cavity 510 works, the cold air in the air supply cavity 510 can be transported into the air supply channel 411. The upper end of the air return channel 421 is in communication with the first refrigeration cavity 120a, and the lower end is in communication with the air return pipe 540. The hot air in the first refrigeration cavity 120a can enter the air return pipe 540 through the air return channel 421, and then be communicated into the air supply cavity 510 by the air return pipe 540.

[0104] 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. 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.
