[0011] In some embodiments, in the vertical direction, the first return air opening is below the first air outlet and the third air outlet.

[0012] In some embodiments, among the first air outlet, the third air outlet and the first return air opening, the first return air opening is away from the rear wall of the refrigeration chamber.

[0013] In some embodiments, the refrigeration chamber is vertically divided into a plurality of refrigeration areas, and each of the refrigeration areas is provided with the first air outlet.

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0046] In addition, reference numbers and / or reference letters can be repeated in different examples in the present application, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements being discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the application of other processes and / or the use of other materials.

[0047] The present application will be described below in combination with the drawings and with reference to specific embodiments:

[0048] In the case of placing a refrigerator and the like in a small-depth environment such as a sideboard, in order to take into account the aesthetics, it is usually required that the refrigerator and the like be in the form of an ultra-thin refrigerator, i.e., the overall thickness of the refrigerator is less than the depth of the placement environment. Since the circulating air cooling channel of the refrigerator is back-mounted and the compressibility is limited, the depth of the internal cavity of the refrigerator is occupied to some extent, which to some extent weakens the storage capacity; and since the internal depth is reduced, the uniformity of air cooling circulation is also affected to some extent, resulting in an unsatisfactory refrigeration effect.

[0049] Therefore, the embodiments of the present application provide a refrigeration device, which aims to improve the storage capacity and refrigeration effect of an ultra-thin refrigerator to some extent, and achieve the technical effect of taking into account the ultra-thin attribute of the refrigerator and good storage capacity and refrigeration performance.

[0050] In some embodiments, the refrigeration equipment adopts a mode of middle refrigeration mechanism, and the refrigeration mechanism and the circulating flow channel are integrated in the middle partition plate separating the refrigerator cavity, leaving a space at the back of the refrigerator, so as to avoid the case that the circulating flow channel arranged at the back occupies the internal volume of the refrigerator, and sufficient space is left for arranging the circulating air port and other structures, so as to balance the small thickness specification, good storage capacity and refrigeration effect.

[0051] Therefore, the middle partition plate of the refrigerator leaves a mounting space for accommodating the refrigeration mechanism and the matching circulating flow channel, and cooperates with the air port structure arranged in the individual cavity of the refrigerator to achieve good circulating air cooling effect.

[0052] Figure 1 The structural schematic diagram of the refrigeration equipment in the embodiment of the application is shown; Figure 4 The structural schematic diagram of the second middle partition plate of the refrigeration equipment in Figure 1 is shown; Figure 7 The second structural schematic diagram of the refrigeration equipment in the embodiment of the application is shown;

[0053] Figure 8 The connection state sectional view of the first middle partition plate and the second middle partition plate in the refrigeration equipment in Figure 7 is shown; Figure 9 The third structural schematic diagram of the refrigeration equipment in the embodiment of the application is shown; Figure 15 The fourth structural schematic diagram of the refrigeration equipment in the embodiment of the application is shown.

[0054] Referring to Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 15 , the refrigeration equipment can include a cabinet 1, and the cabinet 1 can be planned and arranged with one or several of a refrigeration chamber 11, a freezing chamber 12, a drawer chamber 13, a wide-width variable-temperature chamber 14 and a chamber with other functions as needed. Moreover, the refrigeration mechanism 4 can deliver cold air to various functional chambers such as the refrigeration chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14 through the circulating flow channel, and guide the air beam back to the refrigeration mechanism 4, so as to realize the function of circulating refrigeration.

[0055] It is worth emphasizing that, due to the differences in the functional design of the functional chambers such as the refrigeration chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14, the flow or temperature of the cold air delivered to the functional chambers such as the refrigeration chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14 can be different, and independent air door structures can be used for independent control. In order to meet the differentiated refrigeration requirements and the chamber form structure, the planning and arrangement forms of the air outlet and the air return of the above-mentioned functional chambers can also be different, and can be set according to actual needs.

[0056] The refrigeration mechanism in the refrigeration equipment can control the temperature of each functional chamber by the same refrigeration mechanism 4, or can differentially control the temperature of each functional chamber by multiple refrigeration mechanisms.

[0057] Figure 2 A structural diagram of a first partition plate of the refrigeration equipment in Figure 1 is shown; Figure 3 A sectional view of the first partition plate in Figure 2 is shown; Figure 5 A structural diagram of the connection state of the first partition plate and the second partition plate of the refrigeration equipment in Figure 1 is shown; Figure 6 Another angle structural diagram of the connection state of the first partition plate and the second partition plate of the refrigeration equipment in Figure 1 is shown.

[0058] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , in some embodiments, in order to adapt to the working conditions of small space arrangement, a single-system refrigeration mechanism 4 is configured in the refrigeration equipment, and a matching circulating flow channel is configured to realize the circulating refrigeration function of each functional chamber. The box body 1 is provided with a refrigeration chamber 11 and a freezing chamber 12 to realize the functions of refrigeration storage and freezing storage, respectively. The temperature in the refrigeration chamber 11 is higher than the temperature in the freezing chamber 12, and the specific temperature control range can be flexibly set according to needs.

[0059] The refrigeration equipment is also provided with a first partition plate 2 and a second partition plate 3 for separating the functional chambers in the box body 1 to realize the orderly use of the inner cavities of the functional chambers.

[0060] The first partition plate 2 can be arranged in the refrigeration chamber 11 to separate the inner cavity of the refrigeration chamber 11 into multiple independent refrigeration cavities 111, and a first air outlet flow channel 21 is arranged in the first partition plate 2 to guide the refrigeration airflow into the refrigeration chamber 11. A first air outlet 221 is formed on a first side wall 22 of the first partition plate 2, and the multiple refrigeration cavities 111 are respectively communicated with the first air outlet flow channel 21 through the first air outlet 221, so that the refrigeration airflow can enter the multiple refrigeration cavities 111 in sequence through the first air outlet flow channel 21 and the first air outlet 221 to realize refrigeration refrigeration. Since the multiple refrigeration cavities 111 are all communicated with the first air outlet flow channel 21 through the first air outlet 221, the multiple refrigeration cavities 111 in the refrigeration chamber 11 are in a synchronous temperature control mode.

[0061] The second partition plate 3 can be arranged in the freezing chamber 12 to divide the inner cavity of the freezing chamber 12 into a plurality of independent freezing cavities 121, and a second air outlet flow channel 31 is arranged in the second partition plate 3 to guide the refrigeration airflow into the freezing chamber 12. A second air outlet 321 is formed in the second side wall 32 of the second partition plate 3, and the plurality of freezing cavities 121 are respectively communicated with the second air outlet flow channel 31 through the second air outlet 321, so that the refrigeration airflow can enter the plurality of freezing cavities 121 through the second air outlet flow channel 31 and the second air outlet 321 in sequence to realize freezing refrigeration. Since the plurality of freezing cavities 121 are communicated with the first air outlet flow channel 31 through the second air outlet 321, the plurality of refrigerating cavities 111 in the refrigerating chamber 11 are synchronously temperature-controlled.

[0062] In the single-system refrigeration mechanism 4, an air outlet cavity 41 is arranged to be communicated with the air outlet of the refrigeration mechanism 4, for collecting and outputting the refrigeration airflow; and the air outlet cavity 41 is respectively communicated with the first air outlet flow channel 21 and the second air outlet flow channel 31, and the refrigeration airflow in the air outlet cavity 41 is respectively introduced into the first air outlet flow channel 21 and the second air outlet flow channel 31, and then enters the refrigerating cavity 111 and the freezing cavity 121 through the first air outlet 221 and the second air outlet 321 respectively.

[0063] Among them, the air outlet cavity 41 can be formed in the second partition plate 3, and the refrigeration mechanism can also be arranged in the second partition plate 3, so that the internal cavity of the second partition plate 3 can be used to install refrigeration components such as evaporators, fans, etc. The structure of the internal cavity of the second partition plate 3 can be designed to adapt to the installation and fixation of the refrigeration components, and to form a flow channel structure to guide the outflow and backflow of the circulating refrigeration airflow. Of course, the air outlet cavity 41 and the refrigeration mechanism can also be arranged in the first partition plate 2, which can be flexibly selected according to actual conditions, and is not specifically limited here.

[0064] Generally, the second air outlet 221 can be arranged between the second partition plate 3 and the rear wall 122 of the freezing chamber, so as to be relatively far away from the stored objects or storage drawers and the like, which can reduce the risk of the second air outlet 221 being blocked to some extent, ensure the smooth circulation of the airflow, and thus ensure the refrigeration effect; on the other hand, arranging the second air outlet 221 adjacent to the rear wall 122 of the freezing chamber can to some extent leave a spacious space for the freezing drawer and the like, reducing the risk of interference.

[0065] In some embodiments, the first partition plate 2 can be arranged in the refrigerating chamber 11 to divide the inner cavity of the refrigerating chamber 11 into two independent refrigerating cavities 111. The second partition plate 3 can also be arranged in the freezing chamber 12 to divide the inner cavity of the freezing chamber 12 into two independent freezing cavities 121.

[0066] The side wall of the first partition plate 2 adjacent to the refrigeration cavity 111 is a first side wall 22, that is, the side wall of the refrigeration cavity 111 surrounded by the inner wall of the refrigeration chamber 11 is the first side wall 22. The side wall of the second partition plate 3 adjacent to the freezing cavity 121 is a second side wall 32, that is, the side wall of the freezing cavity 121 surrounded by the inner wall of the freezing chamber 12 is the second side wall 32.

[0067] In some embodiments, in order to be close to the rear wall 122 of the freezing chamber, the second air outlet 321 can be arranged at the side wall edge portion 322 of the second partition plate 3. The side wall edge portion 322 is a side edge portion of the second side wall 32 close to the rear wall 122 of the freezing chamber, so that the second air outlet 321 can be arranged in the included angle region between the second partition plate 3 and the rear wall 122 of the freezing chamber.

[0068] Generally, a through hole can be formed in the second side wall 32 as an airflow passage of the second air outlet 321, to communicate the second air outlet flow channel 31 and the freezing cavity 121.

[0069] In order to constrain and guide the air flow of the second air outlet 321, the portion of the rear wall 122 of the freezing chamber adjacent to the second air outlet 321 can be configured as a guide structure 123 of the second air outlet 321. By designing the shape, undulation, angle and other parameters of the guide structure 123, the flow direction and convergence degree of the air flow of the second air outlet 321 can be improved, so that the refrigeration air flow can be stably and uniformly dispersed into the freezing chamber 12 to ensure the refrigeration effect.

[0070] In some embodiments, the second air outlet 321 can also be arranged as an airflow passage surrounded by the second partition plate 3 and the rear wall 122 of the freezing chamber. That is, a hole, slot, opening and other semi-open structures communicating with the second air outlet flow channel 31 can be formed in the second partition plate 3 to form the second air outlet 321 with the rear wall 122 of the freezing chamber, which can simplify the operation of forming the second air outlet 321 on the second partition plate 3 to some extent, save a part of materials, and realize the air guide function structure by the rear wall 122 of the freezing chamber to further simplify the structure of the second partition plate 3 and save materials.

[0071] In some embodiments, in order to meet the partition and layered use requirements of the freezing chamber 12, the freezing cavity 121 in the freezing chamber 12 is usually divided into different sections, so that various forms of structures such as open freezing cavity and drawer freezing cavity are arranged.

[0072] Generally, the second partition plate 3 can be vertically arranged in the freezing chamber 12 to divide the inner cavity of the freezing chamber 12 into two left and right freezing cavities 121; and the freezing chamber can be further vertically divided into a plurality of spaced freezing zones 121a, and the section separation can be realized by a partition plate, a drawer and other separation pieces to facilitate the classified storage of articles.

[0073] At the same time, in order to improve the refrigeration effect of the refrigeration in the multiple closed or semi-closed sections, the second air outlet 321 can be arranged in each freezing zone 121a, so that each freezing zone 121a has a refrigeration airflow flow rate that is substantially equivalent, thereby improving refrigeration uniformity and efficiency.

[0074] In some embodiments, in order to achieve the backflow of the refrigeration airflow in the freezing chamber 12, a second return air flow channel 33 can be arranged in the second partition plate 3, and a second return air outlet 323 can be arranged on the second partition plate 3, and the second return air outlet 323 is in communication with the second return air flow channel 33 and the freezing cavity 121 in the freezing chamber 12, respectively, and the second return air flow channel 33 can be in communication with the return air cavity of the refrigeration mechanism 4, thereby providing a complete backflow channel for the backflow of the refrigeration airflow in the freezing chamber 12 to the refrigeration mechanism 4.

[0075] Considering that cold air is prone to sink, the second return air outlet 323 can be arranged below the second air outlet 321, thereby achieving air outlet at a high position and air return at a low position, prolonging the airflow movement path, and helping to disperse the refrigeration airflow and achieve uniform refrigeration.

[0076] Considering that the second air outlet 321 is close to the rear wall 122 of the freezing chamber, in order to prolong the movement path of the refrigeration airflow, the second return air outlet 323 can also be arranged away from the rear wall 122 of the freezing chamber.

[0077] In some embodiments, in order to facilitate the backflow of the airflow in the refrigerating chamber 11, a first return air flow channel 24 can also be arranged in the first partition plate 2, and a first return air outlet 222 can be arranged on each of the two first side walls 22 of the first partition plate 2, so that the first return air flow channel 24 can be in communication with the two refrigerating cavities 111 through the first return air outlets 222, thereby providing a complete backflow channel for the backflow of the refrigeration airflow in the refrigerating chamber 11 to the refrigeration mechanism 4.

[0078] Considering that cold air is prone to sink, the first return air outlet 222 can be arranged below the first air outlet 221, thereby achieving air outlet at a high position and air return at a low position, prolonging the airflow movement path, and helping to disperse the refrigeration airflow and achieve uniform refrigeration.

[0079] In order to prolong the movement path of the refrigeration airflow, the first air outlet 221 can also be arranged close to the rear wall of the refrigerating chamber 11, and the first return air outlet 222 can be arranged away from the rear wall of the refrigerating chamber 11.

[0080] In some embodiments, in order to meet the zoning and layered use requirements of the refrigerating chamber 11, the refrigerating cavities 111 in the refrigerating chamber 11 are usually divided into different sections, thereby being arranged in various forms of structures such as open refrigerating cavities and drawer refrigerating cavities.

[0081] Generally, the first partition plate 2 can be vertically arranged in the refrigeration chamber 11 to divide the inner cavity of the refrigeration chamber 11 into two refrigeration cavities 111 on the left and right sides; and the refrigeration chamber can be further vertically divided into a plurality of spaced refrigeration areas 111a, and the refrigeration chamber can be divided into sections by a partition plate, a drawer or the like to facilitate classified storage of articles.

[0082] Meanwhile, in order to improve the refrigeration effect of the refrigeration chamber divided into a plurality of closed or semi-closed sections, the first air outlet 221 can be arranged in each refrigeration area 111a, so that each refrigeration area 111a has a refrigeration airflow flow rate that is substantially equivalent, thereby improving refrigeration uniformity and efficiency.

[0083] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, in order to adapt to the differentiated refrigeration needs of different articles, the drawer chamber 13 can also be arranged in the cabinet 1, and a third air outlet flow channel 23 and a third air outlet 223 can be formed in the cabinet 1, and the third air outlet 223 communicates the third air outlet flow channel 23 and the drawer chamber 13, and the third air outlet flow channel 23 communicates with the air outlet cavity 41, thereby realizing an independent refrigeration air outlet structure different from the refrigeration chamber 11, thereby realizing different refrigeration temperature control relative to the refrigeration chamber 11.

[0084] In some embodiments, the drawer chamber 13 can also be divided into sections and layers, and the first partition plate 2 can be extended into the drawer chamber 13 to divide it into two independent drawer cavities 131, and the third air outlet 223 can be arranged in each drawer cavity 131.

[0085] Correspondingly, the third air outlet flow channel 23 can be arranged in the first partition plate 2, and the third air outlet 223 can be arranged on the first side wall 22 on both sides of the first partition plate 2.

[0086] According to the use requirements, the drawer chamber 13 or the drawer cavity 131 can also be vertically divided into sections to form a plurality of drawer areas 131a, thereby realizing a multi-layer drawer structure to meet the needs of classified storage of articles. In order to ensure uniform refrigeration, the third air outlet 223 can be arranged in each drawer area 131a.

[0087] Generally, the height of the third air outlet 223 is slightly higher than the upper edge of the drawer 5, so that the refrigeration airflow can be stably delivered into the drawer 5.

[0088] In some embodiments, since the temperature difference between the refrigeration chamber 11 and the drawer chamber 13 is not large, both of which are refrigeration temperatures above zero degrees, the refrigeration chamber 11 and the drawer chamber 13 can be set as an integrated chamber, sharing the first partition plate 2 and the first return air flow channel 24 and the first return air outlet 222 on the partition plate 2. The drawer chamber 13 and the refrigeration chamber 11 can be separated by a heat-insulating glass.

[0089] Correspondingly, the first air outlet 221 and the third air outlet 223 can be correspondingly arranged above the first return air outlet 222, and the first air outlet 221 and the third air outlet 223 can be closer to the rear wall of the refrigeration chamber 11 relative to the first return air outlet 222, so as to extend the moving path and the diffusion time of the refrigeration airflow to a certain extent, thereby being stored in the refrigeration chamber 11 and the drawer chamber 13.

[0090] In some embodiments, an additional return air outlet can also be arranged on the first partition plate 2 and correspondingly arranged at the lower part of the drawer chamber 13, and the first return air outlet 222 is arranged in the refrigeration chamber 11, which can to a certain extent reduce the risk of poor return air of the refrigeration chamber 11 and the drawer chamber 13.

[0091] Figure 10 A schematic diagram of the assembly state of the flow guide in the refrigeration equipment in Figure 9 is shown; Figure 11 Another angle schematic diagram of the assembly state of the flow guide in Figure 10 is shown; Figure 12 A schematic diagram of the connection state of the second partition plate and the flow guide in the refrigeration equipment in Figure 9 is shown; Figure 13 Another angle schematic diagram of the connection state of the second partition plate and the flow guide in Figure 12 is shown.

[0092] Referring to Figure 2 , Figure 3 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , in some embodiments, in order to adapt to the differentiated freezing needs of different articles, a wide temperature variable chamber 14 can also be arranged in the box body 1, and a fourth air outlet flow channel 61 and a fourth air outlet 631 are opened in the box body 1, and the fourth air outlet 631 communicates the fourth air outlet flow channel 61 and the wide temperature variable chamber 14, and the fourth air outlet flow channel 61 communicates with the air outlet cavity 41, so as to realize an independent refrigeration air outlet structure different from the freezing chamber 12, thereby realizing a freezing temperature control operation different from the freezing chamber 12.

[0093] It is worth mentioning that the damper structure can be arranged on the first air outlet flow channel 21, the second air outlet flow channel 31, the third air outlet flow channel 33 and the fourth air outlet flow channel 61 to control the flow of the flow channel, thereby stably controlling the temperature of each function chamber.

[0094] In some embodiments, one of the two freezing cavities 121 of the freezing chamber 12 separated by the second partition plate 3 can be used as the wide-width variable-temperature chamber 14, but on the second partition plate 3, the second air outlet 321 is not arranged near one side of the wide-width variable-temperature chamber 14, and only the second air outlet 321 is retained near the freezing cavity 121, and the refrigeration airflow is introduced into the freezing cavity 121.

[0095] The independent wide-width variable-temperature refrigeration can be realized through the fourth air outlet flow channel 61 and the fourth air outlet 631 arranged in the cabinet 1.

[0096] In some embodiments, considering that the second partition plate 3 is provided with the second air outlet flow channel 31, if the fourth air outlet flow channel 61 is further arranged in the second partition plate 3, the structural complexity, molding difficulty and overall thickness of the second partition plate 3 will be increased to a certain extent; therefore, the independent air guide member 6 can be arranged in the wide-width variable-temperature chamber 14, the fourth air outlet 631 is arranged on the air guide member 6, and the air guide member 6 is communicated with the air outlet cavity 41, so that the refrigeration airflow can be introduced into the wide-width variable-temperature chamber 14 through the air guide member 6 to realize independent wide-width variable-temperature control, which is not synchronized with the freezing chamber 12, thereby a more flexible stable control scheme can be obtained to meet the freezing storage requirements of different materials.

[0097] In some embodiments, in order to reduce the space occupied by the air guide member 6 in the wide-width variable-temperature chamber 14 and reduce the interference risk and assembly difficulty with the second partition plate 3, the air guide member 6 can be arranged as two segments in communication, i.e., the first air guide segment 62 and the second air guide segment 63. The first air guide segment 62 is connected to the air outlet cavity 41 and arranged at the top of the wide-width variable-temperature chamber 14 or outside the wide-width variable-temperature chamber 14, such as the first air guide segment 62 can be arranged inside the transverse partition region of the cabinet 1, or arranged in the gap between the wide-width variable-temperature chamber 14 and the function chamber such as the refrigeration chamber 11, without occupying too much storage space.

[0098] The second air guide segment 63 can be extended into the wide-width variable-temperature chamber 14 through the adaptive window arranged on the inner container of the wide-width variable-temperature chamber 14, and the fourth air outlet 631 is arranged on the second air guide segment 63.

[0099] The first air guide segment 62 has a first part of the fourth air outlet flow channel 61, the second air guide segment 63 has another part of the fourth air outlet flow channel 61, the first part of the fourth air outlet flow channel 61 and the other part of the fourth air outlet flow channel 61 are communicated, and the first part of the fourth air outlet flow channel 61 and the other part of the fourth air outlet flow channel 61 constitute the complete fourth air outlet flow channel 61.

[0100] In some embodiments, in order to further simplify the structure of the air guide 6, reduce the volume and the amount of material, the second air guide section 63 can be provided as an arc-shaped plate or a half-open pipe or other special-shaped member with a certain groove channel, and the open side edge of the second air guide section 63, such as a notch, is directly buckled on the inner wall 141 of the wide variable temperature chamber 14, thereby forming a closed flow channel structure, that is, another part of the fourth flow channel 61.

[0101] Generally, the contact part of the second air guide section 63 and the inner wall 141 of the wide variable temperature chamber 14 can be sealed as needed to ensure the sealing of the flow channel and to ensure the escape loss of the refrigeration airflow during the flow process.

[0102] In order to improve the refrigeration uniformity in the wide variable temperature chamber 14, a plurality of fourth air outlets 631 can be arranged on the second air guide section 63 of the air guide 6 along the airflow direction in the air guide section 63 to realize stable air outlet in the whole area.

[0103] In some embodiments, the air guide 6 can be integrally formed on the second partition plate 3.

[0104] In some embodiments, considering that the air outlet cavity 41 needs to guide the refrigeration airflow to the first air outlet flow channel 21, the second air outlet flow channel 31, the third air outlet flow channel 23 and the fourth air outlet flow channel 61, the air outlet cavity 41 can be arranged at the abutting position of the refrigerating chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide variable temperature chamber 14, and the distance from the refrigerating chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide variable temperature chamber 14 is kept at a relatively short position, thereby reducing the complexity and overall specifications of the circulating flow channel.

[0105] Generally, the refrigerating chamber 11 and the drawer chamber 13 are usually located at the vertical upper part of the cabinet 1, and the freezing chamber 12 and the wide variable temperature chamber 14 are usually located at the lower part of the cabinet 1, so the second partition plate 3 can be arranged at the lower part of the cabinet 1, and the first partition plate 2 can be arranged at the upper part of the cabinet. Correspondingly, the air outlet cavity 41 can be arranged at the vertical top inner side of the second partition plate 3.

[0106] In some embodiments, in order to simplify the return air structure of the freezing chamber 12 and the wide variable temperature chamber 14, a second return air outlet 323 can be formed on each of the two side walls of the second partition plate 2, that is, the second side wall 32, so that the freezing chamber 12 and the wide variable temperature chamber 14 can respectively pass through the second return air outlet 323 to communicate with the second return air flow channel 33, thereby realizing the shared return air flow channel, and to a certain extent, reducing the difficulty of forming the second partition plate 3, the amount of materials and the complexity of the structure.

[0107] Referring to Figure 15In some embodiments, the cabinet 1 can be provided with a refrigeration chamber 11, a freezing chamber 12, a drawer chamber 13 and a wide-width temperature-adjusting chamber 14 at the same time, so as to meet the requirements of conventional refrigeration and ice-temperature refrigeration, conventional freezing and ice-fresh freezing.

[0108] In order to realize the communication between the air outlet cavity 41 and the first air outlet flow channel 21 and the third air outlet flow channel 23, and the communication between the first air return flow channel 24 and the second air return flow channel 32 and the air return cavity of the refrigeration mechanism 4, the adapter 7 is arranged between the first partition plate 2 and the second partition plate 3.

[0109] The adapter 7 is provided with an air outlet connection flow channel, so as to realize the communication between the air outlet cavity 41 and the first air outlet flow channel 21 and the third air outlet flow channel 23. The second partition plate 3 is further provided with an air return connection flow channel 34, the air return connection flow channel 34 is communicated with the second air return flow channel 323, and the air return connection flow channel 34 can be further communicated with the first air return flow channel 24 through the adapter 7, so as to collect the air return flow in the refrigeration chamber 11 and the drawer chamber 3 and the air return flow in the freezing chamber 12 and the wide-width temperature-adjusting chamber 14, and then introduce the air return flow into the refrigeration mechanism 4.

[0110] In some embodiments, in order to improve the adaptability of the refrigeration equipment to the use conditions, the overall thickness of the refrigeration equipment can be controlled to be an ultra-thin specification according to the specific product form of the refrigeration equipment, such as an ultra-thin refrigerator. The overall thickness specification can be controlled to be 450mm-600mm. The overall thickness of the refrigeration equipment can be specifically 450mm, 460mm, 470mm, 480mm, 490mm, 500mm, 510mm, 520mm, 530mm, 540mm, 550mm, 560mm, 570mm, 580mm, 590mm, 600mm or other specifications.

[0111] The refrigeration equipment provided by the embodiments of the present application is internally provided with a refrigeration chamber, a freezing chamber and a drawer chamber, which respectively realize basic refrigeration, basic freezing and low-temperature refrigeration functions; and the circulating refrigeration flow channel is arranged in the middle partition plate of the cabinet, thereby avoiding the problem of occupying the storage space of the cabinet caused by arranging the circulating flow channel at the back, and the refrigeration equipment can be thinned under the condition of equivalent volume, thereby being more suitable for small-depth installation conditions and meeting the use requirements. Meanwhile, the air outlet of the freezing chamber is arranged between the second middle partition plate and the rear wall of the freezing chamber, and the air outlet is arranged in the corner space, thereby being capable of improving the space utilization rate to a certain extent, and capable of reducing the interference between the air outlet structure and the stored materials and the drawer structure to a certain extent, thereby being capable of improving the smoothness of the refrigeration air flow circulation to a certain extent, thereby ensuring the stability of the refrigeration effect. It is worth noting that, since the air outlet of the freezing chamber is adjacent to the rear wall of the freezing chamber, the rear wall of the freezing chamber can be used as a wind guide structure, thereby being capable of simplifying the air guide structure of the air outlet to a certain extent, simplifying the production process and reducing the cost of generated materials. On the other hand, the first air outlet flow channel of the refrigeration chamber and the second air outlet flow channel of the freezing chamber are both communicated with the air outlet cavity of the refrigeration mechanism, thereby being capable of realizing a single refrigeration system, thereby being capable of reducing the overall equipment size, occupying less space and simplifying the structure of the middle partition plate, which is helpful to improve the production efficiency.
