Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a refrigeration device. Background Technology

[0002] Embedded layouts for appliances such as refrigerators allow them to blend seamlessly with the surrounding structure, effectively balancing space utilization and overall aesthetics. To accommodate layouts with limited depth, the overall thickness of these appliances needs to be ultra-thin.

[0003] However, since the refrigeration system of a refrigerator typically uses a back-mounted design, meaning that the air outlet and return channels are usually located at the rear of the refrigerator, they have a certain thickness and limited compressibility. Therefore, in order to reduce the overall thickness of the refrigerator, the depth of the internal cavity will be reduced, affecting the refrigerator's storage capacity. Furthermore, the reduced depth of the internal cavity also affects the uniformity and effectiveness of the internal air circulation cooling to some extent. Summary of the Invention

[0004] This application provides a refrigeration device designed to at least partially address the technical problems of unsatisfactory storage capacity and refrigeration effect in thin-walled refrigerators. Therefore,

[0005] One aspect of this application provides a refrigeration device, comprising:

[0006] The cabinet has a refrigerator compartment and a freezer compartment;

[0007] A first partition is disposed in the refrigerator compartment, dividing the inner cavity of the refrigerator compartment into two refrigerator compartments. A first air outlet is disposed inside the first partition, and a first air outlet is provided on each of the two side walls of the first partition. The two refrigerator compartments are respectively connected to the first air outlet through the first air outlet.

[0008] A second partition is disposed within the freezer chamber, dividing the inner cavity of the freezer chamber into two freezer chambers. The second partition has an air outlet chamber and a second air outlet channel inside. The air outlet chamber is connected to the second air outlet channel and the first air outlet channel, respectively. Second air outlets are provided on both side walls of the second partition. The two freezer chambers are connected to the second air outlet channel through the second air outlets, and the second air outlets are disposed between the second partition and the rear wall of the freezer chamber.

[0009] In some embodiments, the second air outlet is located on the side wall edge of the second partition, and the side wall edge is the side edge near the rear wall of the freezer compartment.

[0010] In some embodiments, at least a portion of the rear wall of the freezer compartment adjacent to the second air outlet is configured as an air guide structure for the second air outlet.

[0011] In some embodiments, the refrigeration device further includes a refrigeration mechanism disposed within the second partition plate, and the air outlet of the refrigeration mechanism is connected to the air outlet cavity.

[0012] In some embodiments, the second partition is vertically disposed in the freezer chamber, the freezer chamber is vertically divided into multiple freezer zones, and each freezer zone is provided with the second air outlet.

[0013] In some embodiments, a second return air duct is further provided in the second partition, and a second return air outlet is provided on the second partition to connect the freezer chamber and the second return air duct. The second return air outlet is located below the second air outlet, and of the second air outlet and the second return air outlet, the second return air outlet is far away from the rear wall of the freezer chamber.

[0014] In some embodiments, a first return air duct is further provided in the first partition plate, and a first return air inlet is provided on each of the two side walls of the first partition plate, and the first return air duct is connected to two refrigeration chambers through the first return air inlet.

[0015] In some embodiments, the refrigerator compartment is vertically divided into multiple refrigerator zones, and each refrigerator zone is provided with the first air outlet.

[0016] In some embodiments, in the vertical direction, the first return air vent is located below the first air outlet;

[0017] Of the first air outlet and the first air return outlet, the first air return outlet is far from the rear wall of the refrigerator compartment, and the first air outlet is close to the rear wall of the refrigerator compartment.

[0018] In some embodiments, the thickness of the refrigeration device ranges from 450 mm to 600 mm.

[0019] The embodiments of this application have at least the following beneficial effects:

[0020] The refrigeration equipment provided in this application embodiment has a refrigerator compartment and a freezer compartment inside the cabinet, realizing refrigeration and freezing functions respectively; and the circulating refrigeration channel is set in the middle partition of the cabinet, thereby avoiding the problem of encroaching on the storage space of the cabinet caused by the back circulation channel. It can reduce the thickness of the refrigeration equipment with a relatively large volume, thus making it more suitable for shallow depth installation conditions and meeting usage requirements. At the same time, the air outlet of the freezer compartment is set between the second middle partition and the rear wall of the freezer compartment. The air outlet is planned and arranged in the corner space, which can improve the space utilization to a certain extent and reduce the interference between the air outlet structure and the stored materials and drawer structure to a certain extent, thereby improving the smoothness of the refrigeration airflow circulation and ensuring the stability of the refrigeration effect. It is worth noting that since the air outlet of the freezer compartment is adjacent to the rear wall of the freezer compartment, the rear wall of the freezer compartment can be used as the air guide structure, thereby simplifying the air guide structure of the air outlet to a certain extent, simplifying the manufacturing process, and reducing the production consumable costs. On the other hand, by connecting the first air outlet duct of the refrigerator compartment and the second air outlet duct of the freezer compartment to the air outlet cavity of the refrigeration mechanism, a single refrigeration system can be realized, thereby reducing the overall equipment size, occupying less space, and simplifying the structure of the partition, which helps to improve production efficiency.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] When refrigerators and other refrigeration equipment are placed in shallow environments such as sideboards, aesthetics are often prioritized, requiring the equipment to be ultra-thin—meaning the overall thickness of the refrigerator is less than the depth of the space. For example, the refrigerator's overall thickness must be less than the depth of the sideboard. Because the refrigerator's air circulation channel is back-mounted and has limited compressibility, the internal cavity depth is reduced, diminishing storage capacity. Furthermore, the reduced internal depth also affects the uniformity of air circulation, resulting in less than ideal cooling performance.

[0049] Therefore, this application provides a refrigeration device that aims to improve the storage capacity and refrigeration effect of an ultra-thin refrigerator to a certain extent, achieving the technical effect of balancing the ultra-thin attributes of the refrigerator with good storage capacity and refrigeration performance.

[0050] In some embodiments, the refrigeration equipment adopts a centrally located refrigeration mechanism, integrating the refrigeration mechanism and the circulation channel within the partition separating the refrigerator compartments, leaving space at the back of the refrigerator. This avoids the rear-mounted circulation channel encroaching on the internal volume of the refrigerator, leaving sufficient space for the arrangement of structures such as circulation vents, thereby balancing small thickness specifications, good storage capacity, and refrigeration effect.

[0051] Therefore, the refrigerator's middle partition has installation space to accommodate the refrigeration mechanism and the corresponding circulation channel, and works in conjunction with the air vent structure arranged in each cavity of the refrigerator to achieve a good circulating air cooling effect.

[0052] Figure 1 A schematic diagram of the structure of the refrigeration device in an embodiment of this application is shown; Figure 4 It shows Figure 1 A schematic diagram of the structure of the second partition plate of the refrigeration equipment in the middle; Figure 7 A second structural schematic diagram of the refrigeration device in an embodiment of this application is shown;

[0053] Figure 8 It shows Figure 7 A cross-sectional view of the connection between the first and second partitions in the refrigeration equipment. Figure 9 A schematic diagram of a third structure of the refrigeration device in an embodiment of this application is shown; Figure 15 A fourth structural schematic diagram of the refrigeration device in an embodiment of this application is shown.

[0054] See Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 15 The refrigeration equipment may include a housing 1, and the housing 1 may be configured as needed to include one or more of the following: a refrigerator compartment 11, a freezer compartment 12, a drawer compartment 13, a wide-range variable temperature compartment 14, and other functional chambers. Furthermore, the refrigeration mechanism 4 can deliver cold air to the various functional chambers such as the refrigerator compartment 11, freezer compartment 12, drawer compartment 13, and wide-range variable temperature compartment 14 through a circulation channel, and guide the airflow back to the refrigeration mechanism 4, thereby achieving the function of cyclic refrigeration.

[0055] It is worth emphasizing that, due to the differences in the functional design of the refrigerator compartment 11, freezer compartment 12, drawer compartment 13, and wide-range variable temperature compartment 14, the flow rate or temperature of the cold air delivered to these compartments can be different, and independent damper structures can be used for independent control. To meet differentiated cooling needs and compartment shapes, the arrangement of the air outlets and return air inlets for each of the above functional compartments may also differ, and can be tailored to specific requirements.

[0056] In refrigeration equipment, the refrigeration mechanism can use the same refrigeration mechanism 4 to control the temperature of each functional chamber, or it can use multiple refrigeration mechanisms to control the temperature of each functional chamber differently.

[0057] Figure 2 It shows Figure 1 A schematic diagram of the structure of the first partition plate of the refrigeration equipment in the system; Figure 3 It shows Figure 2 A cross-sectional view of the first diaphragm in the middle; Figure 5 It shows Figure 1 A schematic diagram showing the connection structure between the first and second partitions of the refrigeration equipment. Figure 6 It shows Figure 1 Another angle structural diagram of the connection state between the first and second partitions of the refrigeration equipment.

[0058] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, to adapt to the working conditions of small space layout, the refrigeration equipment is equipped with a single-system refrigeration mechanism 4 and a corresponding circulation channel to realize the circulating refrigeration function of each functional chamber. The cabinet 1 is provided with a refrigerator compartment 11 and a freezer compartment 12, which respectively realize the functions of refrigerated storage and frozen storage; wherein, the temperature in the refrigerator compartment 11 is higher than the temperature in the freezer compartment 12, and the specific temperature control range can be flexibly set as needed.

[0059] The refrigeration equipment is also equipped with a first partition 2 and a second partition 3 to separate the functional chambers inside the cabinet 1, so as to realize the orderly use of the internal cavity of the functional chamber.

[0060] The first partition 2 can be installed inside the refrigerator compartment 11, dividing the inner cavity of the refrigerator compartment 11 into multiple independent refrigerator compartments 111. A first air outlet duct 21 is provided inside the first partition 2 to guide the cooling airflow into the refrigerator compartment 11. A first air outlet 221 is provided on the first side wall 22 of the first partition 2, and the multiple refrigerator compartments 111 are respectively connected to the first air outlet duct 21 through the first air outlet 221, so that the cooling airflow can enter the multiple refrigerator compartments 111 sequentially through the first air outlet duct 21 and the first air outlet 221 to achieve refrigeration. Since the multiple refrigerator compartments 111 are all connected to the first air outlet duct 21 through the first air outlet 221, the multiple refrigerator compartments 111 in the refrigerator compartment 11 are in a synchronous temperature control mode.

[0061] The second partition 3 can be installed inside the freezer compartment 12, dividing the inner cavity of the freezer compartment 12 into multiple independent freezer compartments 121. A second air outlet 31 is provided in the second partition 3 to guide the cooling airflow into the freezer compartment 12. A second air outlet 321 is provided on the second side wall 32 of the second partition 3, and the multiple freezer compartments 121 are respectively connected to the second air outlet 321 and the second air outlet 31, so that the cooling airflow can enter the multiple freezer compartments 121 in sequence through the second air outlet 31 and the second air outlet 321 to achieve freezing and refrigeration. Since the multiple freezer compartments 121 are all connected to the first air outlet 31 through the second air outlet 321, the multiple refrigeration compartments 111 in the refrigerator compartment 11 are synchronously temperature controlled.

[0062] In the single-system refrigeration mechanism 4, an air outlet cavity 41 is provided, which can be connected to the air outlet of the refrigeration mechanism 4 for collecting and outputting refrigeration airflow; and the air outlet cavity 41 is connected to the first air outlet channel 21 and the second air outlet channel 31 respectively. The refrigeration airflow in the air outlet cavity 41 is introduced into the first air outlet channel 21 and the second air outlet channel 31 respectively, and then enters the refrigerator cavity 111 and the freezer cavity 121 through the first air outlet 221 and the second air outlet 321 respectively.

[0063] The air outlet cavity 41 can be located within the second partition 3, and the refrigeration mechanism can also be housed within the second partition 3. This allows for the installation of refrigeration components, such as evaporators and fans, within the internal chambers of the second partition 3. The structural design of the internal chambers of the second partition 3 can be adapted to accommodate and fix the refrigeration components, forming a flow channel structure to guide the outflow and return of the circulating refrigeration airflow. Alternatively, the air outlet cavity 41 and the refrigeration mechanism can also be located within the first partition 2; the choice is flexible and based on actual conditions, without specific limitations.

[0064] Generally, the second air outlet 221 can be located between the second partition 3 and the rear wall 122 of the freezer compartment, so that it is relatively far away from the stored items or storage drawers and other structures. This can reduce the risk of the second air outlet 221 being blocked to a certain extent, ensure smooth airflow circulation, and thus ensure the cooling effect. On the other hand, setting the second air outlet 221 close to the rear wall 122 of the freezer compartment can, to a certain extent, leave open space for structures such as freezer drawers and reduce the risk of interference.

[0065] In some embodiments, a first partition 2 may be disposed in the refrigerator compartment 11, dividing the inner cavity of the refrigerator compartment 11 into two independent refrigerator cavities 111. Alternatively, a second partition 3 may be disposed in the freezer compartment 12, dividing the inner cavity of the freezer compartment 12 into two independent freezer cavities 121.

[0066] The first partition 2 is adjacent to the side wall of the refrigerator compartment 111, which is the first side wall 22, forming the refrigerator compartment 111 together with the inner wall of the refrigerator compartment 11. The second partition 3 is adjacent to the side wall of the freezer compartment 121, which is the second side wall 32, forming the freezer compartment 121 together with the inner wall of the freezer compartment 12.

[0067] In some embodiments, in order to be close to the rear wall 122 of the freezer compartment, the second air outlet 321 can be disposed on the side wall edge 322 of the second partition 3. The side wall edge 322 is the side edge of the second side wall 32 that is close to the rear wall 122 of the freezer compartment, so that the second air outlet 321 can be disposed in the angle region between the second partition 3 and the rear wall 122 of the freezer compartment.

[0068] Generally, a through hole can be made in the second side wall 32 to serve as an airflow channel for the second air outlet 321, connecting the second air outlet 31 and the freezing chamber 121.

[0069] To constrain and guide the airflow from the second air outlet 321, the portion of the rear wall 122 of the freezer compartment adjacent to the second air outlet 321 can be configured as a guide structure 123 for the second air outlet 321. By designing the shape, undulation, angle, and other parameters of the guide structure 123, the flow direction and convergence of the airflow from the second air outlet 321 can be improved, ensuring that the cooling airflow can be stably and evenly dispersed into the freezer compartment 12 to guarantee the cooling effect.

[0070] In some embodiments, the second air outlet 321 can also be configured as an airflow channel formed by the second partition 3 and the rear wall 122 of the freezer compartment. That is, a semi-open structure such as a slot or notch connecting the second air outlet channel 31 can be formed on the second partition 3, which together with the rear wall 122 of the freezer compartment forms the second air outlet 321. This can simplify the operation of forming the second air outlet 321 on the second partition 3 to a certain extent and save some materials; and the rear wall 122 of the freezer compartment can be used to realize the air guiding function structure, further simplifying the structure of the second partition 3 and saving materials.

[0071] In some embodiments, in order to meet the requirements of partitioning and layering of the freezer compartment 12, the freezer cavity 121 in the freezer compartment 12 is usually divided into different sections, thereby setting up various forms of structures such as open freezer cavity, drawer freezer cavity, etc.

[0072] Generally, the second partition 3 can be vertically installed in the freezer compartment 12 to divide the inner cavity of the freezer compartment 12 into two freezer compartments 121 on the left and right. Furthermore, the freezer compartment can be vertically divided into multiple interval freezer zones 121a, and the zones can be separated by partitions, drawers and other dividers, which facilitates the classification and storage of items.

[0073] Meanwhile, in order to improve the cooling effect of multiple closed or semi-closed sections, a second air outlet 321 can be provided in each freezing zone 121a, so that each freezing zone 121a has a roughly equal cooling airflow, thereby improving the uniformity and efficiency of cooling.

[0074] In some embodiments, in order to realize the recirculation of the refrigeration airflow in the freezer compartment 12, a second return air duct 33 can be opened in the second partition 3, and a second return air inlet 323 can be opened on the second partition 3. The second return air inlet 323 is connected to the second return air duct 33 and the freezer cavity 121 in the freezer compartment 12, respectively. The second return air duct 33 can be connected to the return air cavity of the refrigeration mechanism 4, thereby providing a complete recirculation channel for the refrigeration airflow in the freezer compartment 12 to return to the refrigeration mechanism 4.

[0075] Considering that cold air tends to sink, the second return air vent 323 can be located below the second air outlet 321, thereby achieving high-level air outlet and low-level air return. By extending the airflow path, it helps to disperse the cooling airflow and achieve uniform cooling.

[0076] Considering that the second air outlet 321 is close to the rear wall 122 of the freezer compartment, in order to extend the movement path of the cooling airflow, the second return air outlet 323 can also be moved away from the rear wall 122 of the freezer compartment.

[0077] In some embodiments, in order to facilitate the airflow recirculation in the refrigerator compartment 11, a first return air duct 24 may be opened in the first partition 2, and a first return air inlet 222 may be opened on the two first side walls 22 of the first partition 2, so that the first return air duct 24 can be connected to the two refrigerator cavities 111 through the first return air inlet 222, thereby providing a complete return channel for the refrigeration airflow in the refrigerator compartment 11 to return to the refrigeration mechanism 4.

[0078] Considering that cold air tends to sink, the first return air vent 222 can be located below the first air outlet 221, thereby achieving high-level air outlet and low-level air return. By extending the airflow path, it helps to disperse the cooling airflow and achieve uniform cooling.

[0079] In order to extend the movement path of the cooling airflow, the first air outlet 221 can be set close to the rear wall of the refrigerator compartment 11, and the first return air outlet 222 can be set away from the rear wall of the refrigerator compartment 11.

[0080] In some embodiments, in order to meet the requirements of partitioning and layering of the refrigerator compartment 11, the refrigerator cavity 111 in the refrigerator compartment 11 is usually divided into different sections, thereby setting up various forms of structures such as open refrigerator cavity, drawer refrigerator cavity, etc.

[0081] Generally, the first partition 2 can be vertically installed in the refrigerator compartment 11 to divide the inner cavity of the refrigerator compartment 11 into two refrigerator compartments 111 on the left and right. Furthermore, the freezer compartment can be vertically divided into multiple refrigeration zones 111a, and the zones can be separated by partitions, drawers and other dividers, which facilitates the classification and storage of items.

[0082] Meanwhile, in order to improve the cooling effect of the multiple closed or semi-closed sections, a first air outlet 221 can be set in each refrigeration zone 111a, so that each refrigeration zone 111a has a roughly equal cooling airflow, thereby improving the uniformity and efficiency of cooling.

[0083] See 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 different refrigeration needs of different items, a drawer compartment 13 may be provided inside the cabinet 1, and a third air outlet 23 and a third air outlet 223 may be opened inside the cabinet 1. The third air outlet 223 is connected to the third air outlet 23 and the drawer compartment 13, and the third air outlet 23 is connected to the air outlet cavity 41, thereby realizing an independent refrigeration air outlet structure that is different from the refrigeration chamber 11, thereby realizing different refrigeration temperature control relative to the refrigeration chamber 11.

[0084] In some embodiments, the drawer compartment 13 can also be partitioned and layered. The first partition 2 can be extended into the drawer compartment 13 to divide it into two independent drawer cavities 131. A third air outlet 223 can be provided in each drawer cavity 131.

[0085] Correspondingly, the third air outlet 23 can be disposed within the first partition plate 2, and the third air outlet 223 can be disposed on the first sidewalls 22 on both sides of the first partition plate 2.

[0086] Depending on usage requirements, the drawer compartment 13 or drawer cavity 131 can be vertically partitioned to form multiple drawer areas 131a, achieving a multi-layer drawer structure to meet the needs of categorized storage of items. To ensure uniform cooling, a third air outlet 223 can be provided in each drawer area 131a.

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

[0088] In some embodiments, since the temperature difference between the refrigerator compartment 11 and the drawer compartment 13 is small, both being refrigeration temperatures of 0 degrees Celsius or above, the refrigerator compartment 11 and the drawer compartment 13 can be configured as an integrated chamber, sharing the first partition 2 and the first return air duct 24 and the first return air vent 222 on the partition 2. The drawer compartment 13 and the refrigerator compartment 11 can be separated by heat-insulating glass.

[0089] Correspondingly, the first air outlet 221 and the third air outlet 223 can be positioned above the first return air outlet 222. The first air outlet 221 and the third air outlet 223 can be closer to the rear wall of the refrigerator compartment 11 than the first return air outlet 222, thereby extending the movement path and dissipation time of the refrigeration airflow to a certain extent, so that it can be stored in the refrigerator compartment 11 and the drawer compartment 13.

[0090] In some embodiments, an additional return air vent may be provided on the first partition 2 and correspondingly provided at the lower part of the drawer compartment 13. The first return air vent 222 is provided inside the refrigerator compartment 11, which can reduce the risk of poor air return in the refrigerator compartment 11 and the drawer compartment 13 to a certain extent.

[0091] Figure 10 It shows Figure 9 A schematic diagram of the assembly state of the flow guide component in the refrigeration equipment; Figure 11 It shows Figure 10 Another perspective view of the assembly state of the guide component in the middle; Figure 12 It shows Figure 9 A schematic diagram showing the connection status of the second partition and the flow guide in the refrigeration equipment. Figure 13 It shows Figure 12 Another angle diagram showing the connection status of the second partition and the flow guide.

[0092] See 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 different freezing needs of different items, a wide variable temperature compartment 14 may be provided in the cabinet 1, and a fourth air outlet 61 and a fourth air outlet 631 may be opened in the cabinet 1. The fourth air outlet 631 is connected to the fourth air outlet 61 and the wide variable temperature compartment 14. The fourth air outlet 61 is connected to the air outlet cavity 41, thereby realizing an independent cooling air outlet structure that is different from the freezer compartment 12, thereby realizing a freezing temperature control operation that is different from the freezer compartment 12.

[0093] It is worth noting that damper structures can be configured on the first air outlet duct 21, the second air outlet duct 31, the third air outlet duct 33, and the fourth air outlet duct 61 to control the flow rate of the ducts, thereby stabilizing the temperature of each functional chamber.

[0094] In some embodiments, one of the two freezing chambers 121 of the freezing chamber 12 separated by the second partition 3 can be used as a wide-range variable temperature chamber 14. However, on the second partition 3, the second air outlet 321 is not opened on the side near the wide-range variable temperature chamber 14, and the second air outlet 321 is only retained on the side near the freezing chamber 121 to introduce cooling airflow into the freezing chamber 121.

[0095] Independent wide-range temperature-controlled cooling can be achieved through the fourth air outlet 61 and the fourth air outlet 631 set inside the housing 1.

[0096] In some embodiments, considering that a second air outlet 31 is provided in the second partition 3, if a fourth air outlet 61 is provided in the second partition 3, it will increase the structural complexity, molding difficulty and overall thickness of the second partition 3 to a certain extent. Therefore, an independent air guide 6 can be provided in the wide-range variable temperature chamber 14, and a fourth air outlet 631 can be opened on the air guide 6. The air guide 6 is connected to the air outlet cavity 41, so that the cooling airflow can be introduced into the wide-range variable temperature chamber 14 through the air guide 6 to achieve independent wide-range variable temperature control, without synchronous control with the freezer chamber 12, thereby obtaining a more flexible and stable control scheme to meet the freezing storage needs of different materials.

[0097] In some embodiments, to reduce the space occupied by the air guide 6 within the wide-area variable temperature compartment 14 and to reduce the risk of interference with the second partition 3 and the difficulty of assembly, the air guide 6 can be configured as two connected sections, namely the first air guide section 62 and the second air guide section 63. The first air guide section 62 is connected to the air outlet cavity 41 and is located at the top of the wide-area variable temperature compartment 14, or outside the wide-area variable temperature compartment 14. For example, the first air guide section 62 can be located inside the transverse partition area of ​​the housing 1, or in the gap between the wide-area variable temperature compartment 14 and its functional chambers such as the refrigerator compartment 11, etc., without occupying too much storage space.

[0098] The second air guide section 63 can extend into the wide-range variable temperature chamber 14 through an adapter window opened on the inner liner of the chamber, and the fourth air outlet 631 is set on the second air guide section 63.

[0099] The first air guide section 62 contains the first part of the fourth air outlet channel 61, and the second air guide section 63 contains the other part of the fourth air outlet channel 61. The first part of the fourth air outlet channel 61 and the other part of the fourth air outlet channel 61 are connected to form a complete fourth air outlet channel 61.

[0100] In some embodiments, in order to further simplify the structure of the air guide 6 and reduce the volume and material usage, the second air guide section 63 can be set as an arc-shaped plate or a semi-open pipe or other irregularly shaped part with a certain groove flow channel; and the open side edge of the second air guide section 63, such as the groove, is directly fastened to the inner wall 141 of the wide-width variable temperature chamber 14, thereby forming a closed flow channel structure, that is, forming another part of the above-mentioned fourth flow channel 61.

[0101] Generally, the contact area between the second air guide section 63 and the inner wall 141 of the wide-area variable temperature chamber 14 can be sealed as needed to ensure the airtightness of the flow channel and prevent the cooling airflow from escaping during the flow process.

[0102] To improve the uniformity of cooling in the wide-area variable temperature chamber 14, multiple fourth air outlets 631 can be set at intervals along the airflow direction in the second air guide section 63 of the air guide component 6 to achieve stable airflow throughout the entire area.

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

[0104] In some embodiments, considering that the air outlet cavity 41 needs to introduce cooling airflow into the first air outlet channel 21, the second air outlet channel 31, the third air outlet channel 23, and the fourth air outlet channel 61, the air outlet cavity 41 can be positioned adjacent to the refrigerator compartment 11, the freezer compartment 12, the drawer compartment 13, and the wide-range variable temperature compartment 14, keeping the distance to the refrigerator compartment 11, the freezer compartment 12, the drawer compartment 13, and the wide-range variable temperature compartment 14 at a relatively short position, thereby reducing the complexity of the circulation channels and the overall specifications.

[0105] Generally, the refrigerator compartment 11 and drawer compartment 13 are usually located in the vertical part of the cabinet 1, while the freezer compartment 12 and wide-range variable temperature compartment 14 are usually located in the lower part of the cabinet 1. Therefore, the second partition 3 can be set in the lower part of the cabinet 1, and the first partition 2 can be set in the upper part of the cabinet. Correspondingly, the air outlet 41 can be set in the inner side of the vertical top of the second partition 3.

[0106] In some embodiments, in order to simplify the return air structure of the freezer 12 and the wide-range variable temperature chamber 14, second return air inlets 323 can be opened on the two side walls of the second partition 2, i.e., the second side wall 32, so that the freezer 12 and the wide-range variable temperature chamber 14 can be connected to the second return air channel 33 through the second return air inlets 323, and share the return air channel, thereby reducing the molding difficulty, material consumption and structural complexity of the second partition 3 to a certain extent.

[0107] See Figure 15In some embodiments, the cabinet 1 may be equipped with a refrigerator compartment 11, a freezer compartment 12, a drawer compartment 13 and a wide-range variable temperature compartment 14, thereby meeting the needs of conventional refrigeration and ice-temperature refrigeration, conventional freezing and chilled freezing.

[0108] In order to ensure the connection between the air outlet cavity 41 and the first air outlet channel 21 and the third air outlet channel 23, as well as the connection between the first return air channel 24 and the second return air channel 32 and the return air cavity of the refrigeration mechanism 4, a connecting piece 7 is provided between the first partition plate 2 and the second partition plate 3.

[0109] The adapter 7 is equipped with an air outlet connection channel, which connects the air outlet cavity 41 with the first air outlet channel 21 and the third air outlet channel 23. The second partition 3 is also equipped with a return air connection channel 34, which is connected to the second return air channel 323. The return air connection channel 34 can also be connected to the first return air channel 24 through the adapter 7, thereby collecting the return airflow in the refrigerator compartment 11 and drawer compartment 3 with the return airflow in the freezer compartment 12 and wide-range temperature control compartment 14 and then introducing it into the refrigeration mechanism 4.

[0110] In some embodiments, to improve the adaptability of the refrigeration equipment to operating 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 ultra-thin, and the overall thickness can be controlled between 450mm and 600mm. The overall thickness of the refrigeration equipment can specifically be 450mm, 460mm, 470mm, 480mm, 490mm, 500mm, 510mm, 520mm, 530mm, 540mm, 550mm, 560mm, 570mm, 580mm, 590mm, 600mm, or other specifications.

[0111] The refrigeration equipment provided in this application embodiment has one or more functional chambers inside the cabinet, including a refrigerator chamber, a freezer chamber, a drawer chamber, and a wide-range variable temperature chamber, which respectively realize basic refrigeration, basic freezing, low-temperature refrigeration, and adjustable temperature freezing functions. The circulating refrigeration channel is located in the middle partition of the cabinet, thus avoiding the problem of encroaching on the storage space caused by a back-mounted circulating channel. This allows for a thinner refrigeration equipment with a relatively large volume, making it more suitable for shallow-depth installations and meeting usage requirements. Simultaneously, the air outlet of the freezer chamber is located between the second middle partition and the rear wall of the freezer chamber, utilizing corner space for air outlet placement. This improves space utilization to some extent and reduces the interference between the air outlet structure and the stored materials and drawer structure, thereby improving the smoothness of the refrigeration airflow circulation and ensuring the stability of the refrigeration effect. It is worth noting that since the freezer compartment's air outlet is adjacent to its rear wall, the rear wall can be used as an air guide structure, which simplifies the air guide structure of the outlet to some extent, simplifies the manufacturing process, and reduces the cost of production materials. On the other hand, by connecting the first air outlet duct of the refrigerator compartment and the second air outlet duct of the freezer compartment to the air outlet cavity of the refrigeration unit, a single refrigeration system can be achieved, thereby reducing the overall equipment size, occupying less space, and simplifying the structure of the partition, which helps to improve production efficiency.
