In order to adapt to some arrangement conditions with small depth, the overall thickness of the electrical equipment such as the refrigerator needs to be set to a small specification, such as an ultra-thin specification.

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction 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 work are within the scope of protection of the present application.

[0049] In addition, the 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 settings 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.

[0050] The present application will be described below in conjunction with the drawings and with reference to specific embodiments:

[0051] In the case of placing a refrigeration device such as a refrigerator in a small-depth environment such as a sideboard, in order to take into account the aesthetics, it is usually required that the refrigeration device such as the refrigerator is in the form of an ultra-thin refrigerator, that is, the overall thickness of the refrigerator is less than the depth of the placement environment; for example, it is required that the overall thickness of the refrigerator is less than the 450mm depth of the sideboard. Since the circulating air cooling channel of the refrigerator is in a back-placed form and the compressibility is limited, the depth of the internal cavity of the refrigerator is occupied, which to some extent weakens the storage capacity; and since the internal depth is reduced, the uniformity of the air cooling circulation is also affected to some extent, resulting in an unsatisfactory refrigeration effect.

[0052] 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 effects of taking into account the ultra-thin attribute of the refrigerator and good storage capacity and refrigeration performance.

[0053] In some embodiments, the refrigeration device adopts a mode of centrally placing the refrigeration mechanism, and the refrigeration mechanism and the circulating channel are integrally arranged 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 back-placed circulating channel occupies the internal volume of the refrigerator, leaving sufficient accommodation space and arranging the circulating air port and other structures, so as to take into account the small thickness specification, good storage capacity and refrigeration effect.

[0054] Therefore, the middle partition plate of the refrigerator leaves a mounting space for accommodating the refrigeration mechanism and the matching circulating channel, and cooperates with the air port structure arranged in the individual cavity of the refrigerator to achieve a good circulating air cooling effect.

[0055] Figure 1 A structural schematic diagram of a refrigeration device in the embodiments of the present application is shown; Figure 4 A structural schematic diagram of a refrigeration device in Figure 1 is shown; Figure 7 A second structural schematic diagram of a refrigeration device in the embodiments of the present application is shown;

[0056] Figure 8 A connection state sectional view of a first middle partition plate and a second middle partition plate in the refrigeration device in Figure 7 is shown; Figure 9 A third structural schematic diagram of a refrigeration device in the embodiments of the present application is shown; Figure 15 A fourth structural schematic diagram of a refrigeration device in the embodiments of the present application is shown.

[0057] Referring to Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 15The refrigeration device can include a cabinet 1, and the cabinet 1 can be provided with one or several of a refrigeration chamber 11, a freezing chamber 12, a drawer chamber 13, a wide-temperature variable chamber 14, and a chamber with other functions according to needs. In addition, 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-temperature variable chamber 14 through a circulating flow channel, and guide the air flow back to the refrigeration mechanism 4, so as to realize the function of circulating refrigeration.

[0058] 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-temperature variable 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-temperature variable chamber 14 can be different, and independent damper structures can be used for independent control. In order to meet the differentiated refrigeration needs and the chamber shape structure, the planning and arrangement forms of the air outlets and air inlets of the above-mentioned functional chambers can also be different, and can be set according to actual needs.

[0059] The refrigeration mechanism in the refrigeration device can use the same refrigeration mechanism 4 to control the temperature of each functional chamber, or use multiple refrigeration mechanisms to differentially control the temperature of each functional chamber.

[0060] Figure 2 A structure diagram of a first partition plate of a refrigeration device in Figure 1 is shown; Figure 3 A sectional view of the first partition plate in Figure 2 is shown; Figure 5 A structure diagram of a connection state of a first partition plate and a second partition plate of a refrigeration device in Figure 1 is shown; Figure 6 Another angle structure diagram of a connection state of a first partition plate and a second partition plate of a refrigeration device in Figure 1 is shown.

[0061] 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 device, and a matching circulating flow channel is configured to realize the circulating refrigeration function of each functional chamber. The cabinet 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.

[0062] The first partition plate 2 and the second partition plate 3 are arranged in the refrigeration equipment, and are used for separating the functional chambers in the cabinet 1 to realize the orderly use of the inner cavities of the functional chambers.

[0063] The first partition plate 2 is arranged in the refrigerating chamber 11, and is used for separating the inner cavity of the refrigerating chamber 11 into a plurality of independent refrigerating cavities 111. The first partition plate 2 is provided with a first air outlet flow channel 21, which is used for guiding the refrigeration airflow into the refrigerating chamber 11. The first side wall 22 of the first partition plate 2 is provided with a first air outlet 221, and the plurality of refrigerating cavities 111 are communicated with the first air outlet flow channel 21 through the first air outlet 221. Therefore, the refrigeration airflow can enter the plurality of refrigerating cavities 111 through the first air outlet flow channel 21 and the first air outlet 221 in sequence, so that the refrigeration cooling is realized. Since the plurality of refrigerating cavities 111 are communicated with the first air outlet flow channel 21 through the first air outlet 221, the plurality of refrigerating cavities 111 in the refrigerating chamber 11 are in a synchronous temperature control mode.

[0064] The second partition plate 3 is arranged in the freezing chamber 12, and is used for separating the inner cavity of the freezing chamber 12 into a plurality of independent freezing cavities 121. The second partition plate 3 is provided with a second air outlet flow channel 31, which is used for guiding the refrigeration airflow into the freezing chamber 12. The second side wall 32 of the second partition plate 3 is provided with a second air outlet 321, and the plurality of freezing cavities 121 are communicated with the second air outlet flow channel 31 through the second air outlet 321. Therefore, 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, so that the freezing cooling is realized. 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 in a synchronous temperature control mode.

[0065] In the single-system refrigeration mechanism 4, an air outlet cavity 41 is arranged, which is communicated with the air outlet of the refrigeration mechanism 4, and is used for collecting and outputting the refrigeration airflow. The air outlet cavity 41 is communicated with the first air outlet flow channel 21 and the second air outlet flow channel 31. The refrigeration airflow in the air outlet cavity 41 is introduced into the first air outlet flow channel 21 and the second air outlet flow channel 31, and then enters the refrigerating cavities 111 and the freezing cavities 121 through the first air outlet 221 and the second air outlet 321 respectively.

[0066] The air outlet cavity 41 can be arranged in the second partition plate 3, and the refrigeration mechanism can also be arranged in the second partition plate 3. Therefore, the internal chamber of the second partition plate 3 can be used to install refrigeration components such as an evaporator, a fan and the like. The refrigeration components can be fixed by designing the structure of the internal chamber of the second partition plate 3, and the flow channel structure can be formed 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. The actual situation can be flexibly selected, and no specific limitation is made here.

[0067] 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 the storage drawer and the like, and to reduce the risk of the second air outlet 221 being blocked to some extent, to ensure the smooth circulation of the air flow, and to ensure the refrigeration effect. On the other hand, the second air outlet 221 is arranged close to the rear wall 122 of the freezing chamber, which can to some extent leave a spacious space for the freezing drawer and the like, and reduce the risk of interference.

[0068] 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.

[0069] The side wall of the first partition plate 2 adjacent to the refrigerating cavity 111 is the first side wall 22, that is, the side wall of the refrigerating cavity 111 surrounded by the inner wall of the refrigerating chamber 11 is the first side wall 22. The side wall of the second partition plate 3 adjacent to the freezing cavity 121 is the 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.

[0070] 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.

[0071] Generally, a through hole can be formed in the second side wall 32 as an air flow passage of the second air outlet 321 to communicate the second air flow channel 31 and the freezing cavity 121.

[0072] In order to constrain and guide the air flow of the second air outlet 321, the portion of the rear wall 122 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 the like 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.

[0073] In some embodiments, the second air outlet 321 can also be formed by the second partition plate 3 and the rear wall 122 of the freezing chamber. That is, a hole, a slot, or a semi-open structure that communicates with the second air outlet flow channel 31 can be formed on the second partition plate 3, and the second air outlet 321 can be formed by the second partition plate 3 and the rear wall 122 of the freezing chamber. This can simplify the operation of forming the second air outlet 321 on the second partition plate 3 to some extent, save a part of the material, and realize the air guide function structure by the rear wall 122 of the freezing chamber, further simplify the structure of the second partition plate 3, and save the material.

[0074] In some embodiments, in order to meet the zoning 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 as to be formed into various structures such as an open freezing cavity and a drawer freezing cavity.

[0075] Generally, the second partition plate 3 can be vertically arranged in the freezing chamber 12, and the inner cavity of the freezing chamber 12 can be divided into two left and right freezing cavities 121. The freezing chamber can be further vertically divided into a plurality of spaced freezing zones 121a, and the section can be separated by a partition plate, a drawer, or the like to facilitate the classified storage of articles.

[0076] At the same time, in order to improve the refrigeration effect of the plurality of 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 substantially equivalent refrigeration airflow flow rate, thereby improving the refrigeration uniformity and efficiency.

[0077] In some embodiments, in order to realize the backflow of the refrigeration airflow in the freezing chamber 12, a second return air flow channel 33 can be formed in the second partition plate 3, and a second return air outlet 323 can be formed on the second partition plate 3, and the second return air outlet 323 respectively communicates with the second return air flow channel 33 and the freezing cavity 121 in the freezing chamber 12. The second return air flow channel 33 can communicate 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.

[0078] Considering that cold air is prone to sink, the second return air outlet 323 can be arranged below the second air outlet 321, thereby realizing the air outlet at a high position and the air return at a low position, prolonging the airflow movement path, and helping to disperse the refrigeration airflow and realize uniform refrigeration.

[0079] 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 be arranged away from the rear wall 122 of the freezing chamber.

[0080] In some embodiments, in order to facilitate the air flow backflow in the refrigeration chamber 11, a first air return flow channel 24 can also be formed in the first partition plate 2, and a first air return port 222 can be formed on each of the two first side walls 22 of the first partition plate 2, so that the first air return flow channel 24 can communicate with the two refrigeration cavities 111 through the first air return ports 222, thereby providing a complete backflow channel for the refrigeration air flow in the refrigeration chamber 11 to return to the refrigeration mechanism 4.

[0081] Considering that cold air tends to sink, the first air return port 222 can be formed below the first air outlet port 221, so that the air is discharged from a high position and returned from a low position, thereby prolonging the air flow movement path and facilitating the dispersion of the refrigeration air flow, and achieving uniform refrigeration.

[0082] In order to prolong the refrigeration air flow movement path, the first air outlet port 221 can be arranged close to the rear wall of the refrigeration chamber 11, and the first air return port 222 can be arranged away from the rear wall of the refrigeration chamber 11.

[0083] In some embodiments, in order to meet the partition and layered use requirements of the refrigeration chamber 11, the refrigeration cavities 111 in the refrigeration chamber 11 are usually divided into different sections, so as to be arranged in the form of open refrigeration cavities, drawer refrigeration cavities and various structures.

[0084] Generally, the first partition plate 2 can be arranged vertically in the refrigeration chamber 11 to divide the inner cavity of the refrigeration chamber 11 into two refrigeration cavities 111; and the refrigeration chamber can be further divided into a plurality of spaced refrigeration zones 111a vertically, and the section division can be achieved by partition plates, drawers and other partition members, thereby facilitating the classified storage of articles.

[0085] At the same time, 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 port 221 can be arranged in each refrigeration zone 111a, so that each refrigeration zone 111a has a refrigeration air flow rate that is substantially equivalent, thereby improving the refrigeration uniformity and efficiency.

[0086] 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 requirements of different articles, the cabinet 1 can further comprise a drawer chamber 13, a third air outlet flow channel 23 and a third air outlet port 223 can be formed in the cabinet 1, the third air outlet port 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, and realizing different refrigeration temperature control relative to the refrigeration chamber 11.

[0087] In some embodiments, the drawer chamber 13 can also be partitioned and layered, and the first partition plate 2 can be extended into the drawer chamber 13 to divide it into two independent drawer cavities 131, and each drawer cavity 131 can be provided with a third air outlet 223.

[0088] 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.

[0089] According to the use requirements, the drawer chamber 13 or the drawer cavity 131 can also be vertically partitioned and arranged to form a plurality of drawer zones 131a, realizing a multi-layered drawer structure form to meet the needs of classified storage of articles. In order to ensure uniform refrigeration, a third air outlet 223 can be arranged in each drawer zone 131a.

[0090] 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.

[0091] In some embodiments, since the temperature difference between the refrigeration chamber 11 and the drawer chamber 13 is not large, both are refrigeration temperatures of zero degrees and above, the refrigeration chamber 11 and the drawer chamber 13 can be arranged 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 refrigeration chamber 11 and the drawer chamber 13 can be separated by a heat-insulating glass.

[0092] Correspondingly, the first air outlet 221 and the third air outlet 223 can be 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, thereby being able to extend the movement path and dissipation time of the refrigeration airflow to a certain extent, thereby being stored in the refrigeration chamber 11 and the drawer chamber 13.

[0093] 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.

[0095] 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 goods, a wide-width variable-temperature room 14 can also be arranged in the cabinet 1, and a fourth air outlet flow channel 61 and a fourth air outlet 631 are formed in the cabinet 1, and the fourth air outlet 631 communicates the fourth air outlet flow channel 61 and the wide-width variable-temperature room 14, and the fourth air outlet flow channel 61 communicates with the air outlet cavity 41, thereby realizing an independent refrigeration air outlet structure different from the freezing room 12, and realizing freezing temperature control operation different from the freezing room 12.

[0096] It is worth noting that damper structures 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, for controlling the flow of the flow channels, thereby stably controlling the temperature of each functional chamber.

[0097] In some embodiments, one of the two freezing cavities 121 of the freezing room 12 separated by the second partition plate 3 can be used as the wide-width variable-temperature room 14, but on the second partition plate 3, the second air outlet 321 is not formed on the side close to the wide-width variable-temperature room 14, and only the second air outlet 321 is retained on the side close to the freezing cavity 121, to introduce refrigeration airflow to the freezing cavity 121.

[0098] 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.

[0099] 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 arranged in the second partition plate 3, it will increase the structural complexity, molding difficulty and overall thickness of the second partition plate 3 to some extent; therefore, an independent air guide 6 can be arranged in the wide-width variable-temperature room 14, the fourth air outlet 631 is formed on the air guide 6, and the air guide 6 is communicated with the air outlet cavity 41, so that the refrigeration airflow can be introduced into the wide-width variable-temperature room 14 through the air guide 6, realizing independent wide-width variable-temperature control, not synchronized control with the freezing room 12, thereby being able to obtain a more flexible stable control scheme to meet the freezing storage needs of different goods.

[0100] In some embodiments, in order to reduce the space occupied by the air guide 6 in the wide temperature changing room 14 and reduce the risk of interference with the second partition 3 and the assembly difficulty, the air guide 6 can be arranged as two sections in communication, i.e., a first air guide section 62 and a second air guide section 63. The first air guide section 62 is connected to the air outlet cavity 41 and is arranged at the top of the wide temperature changing room 14 or outside the wide temperature changing room 14, such as the first air guide section 62 can be arranged inside the transverse partition area of the cabinet 1, or arranged in the gap between the wide temperature changing room 14 and the function cavities such as the refrigeration chamber 11, without occupying too much storage space.

[0101] The second air guide section 63 can extend into the wide temperature changing room 14 through an adaptive window formed on the inner container of the wide temperature changing room 14, and the fourth air outlet 631 is arranged on the second air guide section 63.

[0102] The first air guide section 62 has a first part of the fourth air outlet flow channel 61, the second air guide section 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 in communication, 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 a complete fourth air outlet flow channel 61.

[0103] In some embodiments, in order to further simplify the structure of the air guide 6, reduce the volume and material usage, the second air guide section 63 can be arranged as a class arc-shaped plate or a half-open pipe or other special-shaped members with a certain groove flow channel, and the open side edge of the second air guide section 63, such as the slot part, is directly buckled on the inner wall 141 of the wide temperature changing room 14, thereby forming a closed flow channel structure, i.e., forming the other part of the fourth flow channel 61.

[0104] Generally, the contact part of the second air guide section 63 and the inner wall 141 of the wide temperature changing room 14 can be sealed according to needs to ensure the sealing of the flow channel and ensure the escape loss of the refrigeration airflow during the flow process.

[0105] In order to improve the refrigeration uniformity in the wide temperature changing room 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.

[0106] In some embodiments, the air guide 6 can be integrally formed on the second partition 3.

[0107] 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 position adjacent to the refrigerating chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14, and the distance to the refrigerating chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14 is kept at a relatively short position, so as to reduce the complexity and overall size of the circulation flow channel.

[0108] 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-width 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 is arranged at the upper part of the cabinet. Correspondingly, the air outlet cavity 41 can be arranged inside the vertical top of the second partition plate 3.

[0109] In some embodiments, in order to simplify the air return structure of the freezing chamber 12 and the wide-width variable-temperature chamber 14, a second air return opening 323 can be formed on the two side walls of the second partition plate 2, i.e. the second side wall 32, so that the freezing chamber 12 and the wide-width variable-temperature chamber 14 can respectively pass through the second air return opening 323 to communicate with the second air return flow channel 33, so as to realize the shared air return flow channel, thereby being able to reduce the forming difficulty, material consumption and structural complexity of the second partition plate 3 to a certain extent.

[0110] Referring to Figure 15 In some embodiments, the cabinet 1 can be simultaneously provided with the refrigerating chamber 11, the freezing chamber 12, the drawer chamber 13 and the wide-width variable-temperature chamber 14, so as to meet the requirements of conventional refrigeration and ice-temperature refrigeration, conventional freezing and ice-fresh freezing.

[0111] In order to consider 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, 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.

[0112] The adapter 7 is provided with an air outlet connection flow channel, which realizes 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, which communicates with the second air return flow channel 323, and the air return connection flow channel 34 can also communicate with the first air return flow channel 24 through the adapter 7, so as to collect the air return airflow in the refrigerating chamber 11 and the drawer chamber 13 and the air return airflow in the freezing chamber 12 and the wide-width variable-temperature chamber 14, and then pass them into the refrigeration mechanism 4.

[0113] In some embodiments, in order to improve the adaptability of the refrigeration equipment to the use conditions, the specifications of the refrigeration equipment can be set according to the specific product form of the refrigeration equipment, such as an ultra-thin refrigerator. The overall thickness of the refrigeration equipment is controlled to be an ultra-thin specification, and 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.

[0114] The refrigeration equipment provided by the embodiments of the present application is provided with a refrigeration chamber, a freezing chamber, a drawer chamber and a wide-width variable-temperature chamber inside the cabinet, which respectively realize the functions of basic refrigeration, basic freezing, low-temperature refrigeration and adjustable-temperature freezing. 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 being able to thin the refrigeration equipment 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 by utilizing the corner space, thereby being able to improve the space utilization rate to a certain extent, and being able to reduce the interference between the structure of the air outlet and the stored materials and the drawer structure to a certain extent, thereby being able to improve 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 able to simplify the wind guide structure of the air outlet to a certain extent, simplify the production process and reduce 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 in communication with the air outlet cavity of the refrigeration mechanism, thereby being able to realize a single refrigeration system, thereby being able to reduce the overall equipment size, occupy less space and simplify the structure of the middle partition plate, which is helpful to improve the production efficiency.
