[0055] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0056] Reference below Figures 1-9 A storage device according to an embodiment of the present application is described.

[0057] It should be noted that the storage equipment in this embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has diverse structural forms and a wide range of applications.

[0058] Reference Figures 1 to 4 In one embodiment, the storage device 100 includes a box body 110 and a first air duct portion 120 .

[0059] The box body 110 includes a first inner liner 111, and the two side walls of the first inner liner 111 opposite to each other along the left and right directions are both provided with a clamping portion 1111, and the inner bottom wall of the first inner liner 111 is provided with a stop portion 1112. The first air duct portion 120 has two abutting surfaces opposite to the two side walls, and each of the abutting surfaces is provided with a matching portion 121 adapted to the corresponding clamping portion 1111. The upper end of the first air duct portion 120 is suitable for being movably connected to the inner top wall of the first inner liner 111, so that the lower end of the first air duct portion 120 is suitable for rotating around an axis extending in the left and right directions. When the lower end of the first air duct portion 120 moves to abut against the stop portion, the matching portion 121 is suitable for being assembled with the clamping portion 1111.

[0060] According to the storage device 100 of the present application, the upper end of the first air duct portion 120 is movably connected to the inner top wall of the first inner liner 111, and the lower end can rotate about a left-right axis. This design allows the first air duct portion 120 to be flexibly assembled with the first inner liner 111. The adaptive assembly of the mating portion 121 and the clamping portion 1111 further simplifies the installation process and improves installation efficiency. It also facilitates disassembly for cleaning, repair, or component replacement. When the lower end of the first air duct portion 120 moves to abut the stop portion 1112, the mating portion 121 and the clamping portion 1111 mate and assemble, ensuring a stable connection between the first air duct portion 120 and the first inner liner 111. This structural design effectively prevents the air duct portion from shifting or falling off during use, ensuring the overall stability and reliability of the storage device 100. Because the first air duct portion 120 can rotate about its axis, this design allows it to adapt to different installation environments and space requirements, reducing assembly difficulty. At the same time, the adaptive design of the matching portion 121 and the clamping portion 1111 also has a certain degree of compatibility, and can adapt to components of different specifications and models, thereby improving the adaptability and flexibility of the storage device 100.

[0061] Reference Figure 2 and Figure 3In one embodiment, the inner top wall of the first liner 111 is provided with a mounting groove 1113, and the upper end of the first air duct portion 120 is provided with a mounting arm 122. In the front-to-back direction, the width of the mounting arm 122 is smaller than the width of the mounting groove 1113, so that when the mounting arm 122 is installed in the mounting groove 1113, the lower end of the first air duct portion 120 is suitable for rotating around an axis extending in the left-right direction. In this way, by providing the mounting groove 1113 on the inner top wall of the first liner 111 and providing a mounting arm 122 adapted thereto at the upper end of the first air duct portion 120, the installation and removal process becomes very simple. The mounting arm 122 can be easily inserted into or removed from the mounting groove 1113 without the use of complex tools or cumbersome operations, thereby greatly improving the efficiency of installation and removal. Although the width of the mounting arm 122 is smaller than the width of the mounting groove 1113, this design can still ensure a stable connection between the first air duct portion 120 and the first liner 111. The positioning of the mounting arm 122 in the mounting slot 1113 can prevent the first air duct portion 120 from shifting or falling off during use, thereby ensuring the overall stability and reliability of the storage device 100. Since the width of the mounting arm 122 is smaller than the width of the mounting slot 1113, this design allows the first air duct portion 120 to still have a certain degree of freedom after installation. This allows the lower end of the first air duct portion 120 to rotate around an axis extending in the left and right directions to adapt to different installation environments and space requirements. This flexibility makes the storage device 100 more flexible and changeable in installation and layout. The gap between the mounting arm 122 and the mounting slot 1113 can reduce interference and friction between the two, helping to reduce noise and wear, thereby extending the service life of the equipment.

[0062] Reference Figures 2 to 4In one embodiment, the stop portion 1112 has a first stop surface 11121 facing forward. The first stop surface 11121 is tilted forward from top to bottom. A contact sliding surface 123 corresponding to the stop surface is formed at the lower end of the first air duct portion 120. The contact sliding surface 123 is adapted to slide and abut against the first stop surface 11121. As the first stop surface 11121 is tilted forward from top to bottom, the contact sliding surface 123 naturally slides along the first stop surface 11121 as the lower end of the first air duct portion 120 gradually approaches the stop portion 1112. This design enables automatic alignment and positioning of the first air duct portion 120 during installation, simplifying the installation process and improving installation efficiency. The tilted first stop surface 11121 not only provides a sliding path for the contact sliding surface 123 but also serves to guide the movement direction of the air duct portion. This helps ensure that the first air duct portion 120 moves in the intended direction during installation, avoiding deviations and errors during installation. When the lower end of the first air duct portion 120 moves to abut the stopper 1112, the close fit between the abutting sliding surface 123 and the first stopper surface 11121 ensures a stable connection between the two. This design enhances the structural stability between the first air duct portion 120 and the housing 110, preventing the air duct portion from shifting or falling off during use. Because the abutting sliding surface 123 and the first stopper surface 11121 are in sliding contact, this design reduces friction and wear between them. This helps reduce noise and extend the service life of the device. Because the first stopper surface 11121 is inclined, it can accommodate the abutting sliding surface 123 of first air duct portions 120 of different shapes and sizes to a certain extent. This design increases installation flexibility and adaptability, allowing different types of air duct portions to be smoothly assembled with the stopper 1112.

[0063] Reference Figures 2 to 4In one embodiment, the stopper 1112 further includes an upwardly disposed support surface 11122 connected to the first stopper surface 11121. A downwardly disposed bearing surface 124 connected to the abutting sliding surface 123 is formed at the lower end of the first air duct portion 120. The bearing surface 124 is adapted to abut against the support surface 11122. The arrangement of the support surface 11122 and the bearing surface 124 provides an additional support point when the first air duct portion 120 abuts the stopper 1112, in addition to the sliding contact between the abutting sliding surface 123 and the first stopper surface 11121. This dual support structure significantly improves the connection stability between the first air duct portion 120 and the housing 110, preventing the air duct portion from shaking or shifting during use. The abutment between the support surface 11122 and the bearing surface 124 disperses the force acting on the first air duct portion 120 over a larger area, thereby reducing the pressure per unit area. This helps reduce the risk of structural damage caused by uneven force and improves the durability of the first air duct section 120. The design of the support surface 11122 and the bearing surface 124 provides a clearer positioning reference for the installation of the first air duct section 120. During the installation process, the relative position of the bearing surface 124 and the support surface 11122 can be adjusted to ensure that the first air duct section 120 is accurately aligned and installed in place, thereby improving the accuracy and reliability of the installation. The support surface 11122 is set upward, forming a nested structure with the bearing surface 124, which helps to achieve a more compact installation in a limited space. This design optimizes the space utilization of the storage device 100, making the entire structure more compact and efficient. When the first air duct section 120 needs to be maintained or replaced, the design of the support surface 11122 and the bearing surface 124 makes the disassembly process simpler and more convenient. The air duct section can be easily removed from the box body 110 by simply releasing the abutment relationship between the two, reducing maintenance costs and time costs.

[0064] Reference Figures 2 to 4In one embodiment, the support surface 11122 and the first stop surface 11121 are connected by a circular arc transition. This circular arc transition between the support surface 11122 and the first stop surface 11121 can reduce stress concentration that can occur with right-angle or sharp-angle connections. This design disperses force, reducing the risk of fracture or damage when subjected to external forces, thereby enhancing the strength and durability of the entire structure. When the lower end of the first air duct portion 120 contacts and slides against the stop portion 1112, the circular arc transition provides a smoother transition, reducing friction and resistance. This facilitates smoother sliding of the first air duct portion 120 during installation and removal, improving operational convenience and efficiency. The circular arc transition design reduces collisions and impacts between the components, reducing the resulting noise and vibration. This not only improves the user experience but also helps extend the lifespan of the device. The circular arc transition creates a more natural and smooth connection between the support surface 11122 and the first stop surface 11121, enhancing the overall aesthetics of the structure. This design conforms to modern aesthetic concepts, making the storage device 100 more attractive in appearance.

[0065] Reference Figures 2 to 4 In one embodiment, the abutting sliding surface 123 and the bearing surface 124 are connected by a circular arc transition. This circular arc transition between the abutting sliding surface 123 and the bearing surface 124 allows for a smoother transition between the two during contact and sliding. This design reduces the friction and resistance that may be generated by right-angle or acute-angle connections, allowing the first air duct portion 120 to slide more smoothly during installation and removal, improving operational convenience and efficiency. The circular arc transition design reduces wear and noise caused by friction during the movement of the first air duct portion 120. This not only extends the service life of the device but also improves the user experience. The circular arc transition connection provides a more stable and reliable connection between the abutting sliding surface 123 and the bearing surface 124. This design allows the two to better maintain their connection when subjected to external forces, reducing the risk of structural damage caused by uneven force and enhancing the stability of the entire structure. The circular arc transition connection makes the connection between the abutting sliding surface 123 and the bearing surface 124 smoother and more natural, enhancing the overall aesthetic appearance of the structure. This design conforms to modern aesthetic concepts, making the storage device 100 more attractive in appearance.

[0066] Reference Figures 2 to 4In one embodiment, one of the engaging portion 1111 and the mating portion 121 includes an elastic protrusion, and the other includes a slot 192. The combination of the elastic protrusion and slot 192 facilitates quick and easy installation and removal of the first air duct portion 120. During installation, the user simply aligns the elastic protrusion with the slot 192 and applies slight pressure, allowing the protrusion to snap smoothly into place. For removal, simply pull the elastic protrusion out of the slot 192 with a slight force, eliminating the need for special tools or complex manipulation. The tight fit between the elastic protrusion and slot 192 ensures a stable connection between the first air duct portion 120 and the first inner liner 111. Once the elastic protrusion engages the slot 192, the friction between them prevents the air duct portion from shifting or falling off during use, thereby ensuring the overall stability and reliability of the storage device 100. Due to the elasticity of the elastic protrusion, it can accommodate slots 192 of varying sizes and shapes within a certain range. This design ensures a certain degree of compatibility and interchangeability between the snap-fitting portion 1111 and the mating portion 121, allowing for adaptability to components of different specifications and models, thereby improving the adaptability and flexibility of the storage device 100. The tight integration of the elastic snap-fitting protrusion and the slot 192 can also reduce noise caused by loose components or vibrations. This design helps improve the user experience and makes the storage device 100 quieter and more stable during operation. The elastic snap-fitting protrusion and the slot 192 are relatively simple to manufacture and can be achieved through processes such as injection molding and stamping, reducing manufacturing costs and difficulty. At the same time, this design also facilitates subsequent maintenance and replacement of components.

[0067] Reference Figure 3In one embodiment, the mating portion 121 includes an elastic latch. The two side panels of the first inner liner 111, which are arranged opposite each other in the left-right direction, are bent sequentially from the outside to the inside, so that each side panel includes a first panel segment 1114, a second panel segment 1115, and a third panel segment 1116, which are sequentially connected. The first panel segment 1114 and the third panel segment 1116 are spaced apart from each other in the outside-inward direction. A relief groove 131 is provided at the connection between the second panel segment 1115 and the third panel segment 1116. The relief groove 131 is connected to the inner cavity of the inner liner. When the lower end of the first air duct portion 120 rotates about an axis extending in the left-right direction, the elastic latch is adapted to pass through the relief groove 131 and be snapped into the snap-in groove 192. Thus, the mating portion 121 including the elastic latch makes installation and removal simple and quick. Furthermore, the side panel design of the first inner liner 111 allows the elastic latch to easily pass through the relief groove 131 and snap into the snap-in groove 192, further simplifying the installation process. The coordination between the elastic protrusion and the slot 192 ensures a stable connection between the first air duct portion 120 and the first inner liner 111. This design reduces the possibility of loosening and falling off between components, thereby improving the stability of the entire structure. The avoidance groove 131 is connected to the inner cavity of the inner liner, which not only provides space for the elastic protrusion to pass through, but also helps to optimize space utilization, making the overall structure more compact. This design simplifies the installation and disassembly process, reduces the difficulty of operation, and thus improves work efficiency. At the same time, the stable structure also reduces the maintenance and replacement work caused by loose or falling components.

[0068] In one embodiment, the first air duct portion 120 and the first inner liner 111 are threadedly connected by a screw connector. In this way, the threaded connection of the screw connector makes the installation and disassembly between the first air duct portion 120 and the first inner liner 111 simple and quick. The user can tighten or loosen the two by simply rotating the screw connector without using special tools or performing complicated operations. By rotating the screw connector, the user can easily adjust the tightness of the connection to adapt to different work requirements and scenarios. This adjustability helps to ensure the stability and safety of the connection. In addition, the manufacturing cost of the threaded connection is relatively low. The design of the screw connector and the thread is simple, and the manufacturing process is easy to control, which helps to reduce the overall cost. Since the disassembly and reinstallation of the threaded connection are relatively simple, when the first air duct portion 120 or the first inner liner 111 needs to be repaired or replaced, the user can quickly complete the relevant operations, reducing maintenance costs and time costs.

[0069] Reference Figure 2 and Figure 5In one embodiment, the chamfer of the lower end of the first air duct portion 120 is set to a rounded chamfer. In this way, the rounded chamfer design enables the lower end of the first air duct portion 120 to pass through possible narrow spaces or gaps more smoothly during the process of being inserted or installed into the first inner liner 111, thereby reducing scratches and damage to other components or structures. Since the rounded chamfer can reduce the resistance during installation, the installation process is smoother, thereby improving the installation efficiency. Sharp corners are more likely to break or break when subjected to external forces, and the rounded chamfer design can disperse these stresses, enhance the safety of the structure, and reduce the risk of damage during use. The rounded chamfer makes the appearance of the lower end of the first air duct portion 120 more rounded and smooth, conforms to modern aesthetic concepts, and enhances the overall aesthetics of the storage device 100. The rounded chamfer design also helps to reduce the noise and vibration generated when the air duct portion contacts other components, thereby enhancing the user experience of the device.

[0070] Reference Figure 2 In one embodiment, the first air duct portion 120 is suitable for dividing the first inner liner 111 into a refrigeration chamber 1117 and a freezer chamber 1118. An evaporator is installed in the refrigeration chamber 1117. The first air duct portion 120 is formed with a refrigeration return air duct and a refrigeration outlet air duct. The refrigeration return air port 125 of the refrigeration return air duct and the refrigeration outlet air port 126 of the refrigeration outlet air duct are both connected to the freezer chamber 1118. The refrigeration exhaust port 127 of the refrigeration return air duct and the refrigeration air inlet 128 of the refrigeration outlet air duct are both connected to the refrigeration chamber 1117. In this way, the arrangement of the refrigeration chamber 1117 and the freezer chamber 1118 allows the functional areas of the device to be divided into zones. The refrigeration chamber 1117 is responsible for generating cold, while the freezer chamber 1118 is used to store items that need to be frozen. This design makes the generation and storage of cold more efficient and improves the refrigeration effect of the entire device. The arrangement of the refrigeration return air duct and the refrigeration outlet air duct allows the air in the freezer chamber 1118 to form an effective circulation. The refrigeration return air vent 125 draws in the hot air in the freezer compartment 1118 and discharges it into the refrigeration cavity 1117 through the refrigeration exhaust vent 127, while the cold air in the refrigeration cavity 1117 enters the refrigeration outlet duct through the refrigeration air inlet 128 and is finally sent into the freezer compartment 1118 through the refrigeration outlet 126, thus completing the refrigeration cycle. This design not only improves the freezing effect, but also helps to maintain a stable temperature in the freezer compartment 1118. Due to the reasonable layout of the refrigeration return air duct and the refrigeration outlet duct, the exchange of cold air and hot air is more efficient, reducing energy waste. At the same time, the evaporator is installed in the refrigeration cavity 1117 and can directly cool the air in the refrigeration cavity 1117, further improving energy efficiency. By dividing the first inner tank 111 into different functional areas and setting corresponding air ducts, the structure of the entire device is made more reasonable and compact.

[0071] Reference Figure 1 and Figure 8 In one embodiment, the housing 110 further includes a second inner liner 112, spaced vertically from the first inner liner 111. The second inner liner 112 includes a refrigerated compartment 1121 and a variable temperature chamber 1122, spaced apart from each other. This arrangement effectively utilizes the vertical space of the housing 110. The compartmentalized design of the refrigerated compartment 1121 and the variable temperature chamber 1122 provides a more suitable storage environment for different types of food. The refrigerated compartment 1121 is suitable for foods that require a lower temperature for freshness, while the variable temperature chamber 1122 can adjust its temperature based on the food's needs, enabling more flexible storage. Because the refrigerated compartment 1121 and the variable temperature chamber 1122 are independent, each area can be temperature-controlled independently, ensuring that the temperature in each area precisely meets food storage requirements. Through rational zoning and independent control, unnecessary energy consumption can be reduced, improving the energy efficiency of the entire storage device 100. This design allows users to more conveniently manage and store food, enhancing user convenience and satisfaction.

[0072] The storage device 100 also includes a combined air duct portion 140, which is installed in the second liner 112. The combined air duct portion 140 is formed with a combined return air duct and a combined air outlet duct. The combined air outlet duct includes a refrigerated air outlet duct 141 and a temperature-variable air outlet duct 142. The combined return air duct includes a refrigerated return air duct and a temperature-variable return air duct. The refrigerated air outlet 1411 of the refrigerated air outlet duct 141 and the refrigerated return air duct 1431 are both connected to the refrigerated chamber 1121. The refrigerated air inlet 1412 of the refrigerated air outlet duct 141 and the temperature-variable air outlet duct 142 are connected to the refrigerated chamber 1121. The variable temperature air inlet 1421 of the air outlet 142 is adapted to be connected to the refrigeration chamber 1117. The variable temperature air outlet 1422 of the variable temperature air outlet 142 and the variable temperature return air outlet 1441 of the variable temperature return air duct are both connected to the variable temperature chamber 1122. The variable temperature air outlet 1442 of the variable temperature return air duct and the refrigerated air outlet 1432 of the refrigerated return air duct are both connected to the refrigeration chamber 1117. Thus, the design of the combined air duct portion 140 enables the refrigeration chamber 1121 and the variable temperature chamber 1122 to have independent air outlets and return air ducts, which helps to achieve more precise temperature control. The refrigeration air outlet 141 and the refrigeration return air duct ensure that the temperature in the refrigeration chamber 1121 is stable and uniform, while the variable temperature air outlet 142 and the variable temperature return air duct can adjust the temperature according to the needs of the variable temperature chamber 1122, achieving flexible temperature control. Through independent air outlet and return ducts, the combined air duct unit 140 promotes air circulation within the refrigerating chamber 1121 and the variable temperature chamber 1122. Cold air can flow more efficiently within the refrigerating chamber 1121 and the variable temperature chamber 1122, reducing temperature blind spots and improving cooling efficiency. Because air circulation is more efficient, energy waste is reduced, improving the energy efficiency ratio of the storage device 100. At the same time, through precise temperature control, unnecessary cooling power consumption can also be reduced, further reducing energy consumption. By optimizing air circulation and precisely controlling temperature, the combined air duct unit 140 helps to improve the preservation effect of food and extend the shelf life of food.

[0073] Reference Figure 6 and Figure 8In one embodiment, the storage device 100 further includes a fan assembly 150, which is located between the first inner liner 111 and the second inner liner 112 and is connected to the first air duct portion 120 and the combined air duct portion 140. The fan assembly 152 is adapted to transport the cold air in the refrigeration chamber 1117 to the freezing air inlet 128 of the freezing air outlet duct, the refrigeration air inlet 1412 of the refrigeration air outlet duct 141, and the variable temperature air outlet duct 142. The variable temperature air inlet 1421 is connected to the refrigeration chamber 1117, and is suitable for discharging the gas from the refrigeration exhaust 127 of the refrigeration return air duct, the refrigeration exhaust 1432 of the refrigeration outlet duct 141, and the variable temperature air outlet 1442 of the variable temperature return air duct. In this way, the fan assembly 150 can quickly and effectively transport the cold air in the refrigeration chamber 1117 to the refrigeration inlet 128 of the refrigeration outlet duct, the refrigeration inlet 1412 of the refrigeration outlet duct 141, and the variable temperature air inlet 1421 of the variable temperature outlet duct 142. This means that whether it is a freezing, refrigeration or variable temperature area, the required cold air can be quickly obtained to ensure that the food is properly cooled and kept fresh. Through the operation of the fan assembly 150, the air forms an effective circulation between the freezing, refrigeration and variable temperature areas. This helps to reduce temperature fluctuations, maintain the stability of the temperature of each area, and improve the air circulation within the entire storage device 100. The fan assembly 150 can adjust the wind speed and cool air flow rate as needed, avoiding energy waste. Furthermore, optimized air circulation also helps improve cooling efficiency and reduce energy consumption. The fan assembly 150 is located between the first inner liner 111 and the second inner liner 112, making maintenance and cleaning easier. If the fan assembly 150 needs to be replaced or repaired, there is no need to disassemble the entire storage device 100.

[0074] Reference Figure 5 、 Figure 6 、 Figure 8 as well as Figure 9In one embodiment, the combined air duct portion 140 includes a second air duct portion 145 and a third air duct portion 146 that are separately arranged. A portion of the second air duct portion 145 is arranged corresponding to the temperature-changing chamber 1122, and the other portion is arranged corresponding to the refrigerating chamber 1121. The third air duct portion 146 is arranged corresponding to the refrigerating chamber 1121. The adjacent ends of the second air duct portion 145 and the third air duct portion 146 are abutted, and the second air duct portion 145 and the third air duct portion 146 are both connected to the second inner liner 112. In this way, by splitting the combined air duct portion 140 into the second air duct portion 145 and the third air duct portion 146, the entire air duct system is more flexible in structure. The split design allows the second air duct portion 145 and the third air duct portion 146 to be installed separately, simplifying the installation process. At the same time, during maintenance, a certain air duct portion can be operated separately without disassembling the entire combined air duct portion 140, thereby improving the convenience of maintenance. A portion of the second air duct section 145 corresponds to the variable temperature chamber 1122, while another portion corresponds to the refrigeration chamber 1121. The third air duct section 146 is specifically designed for the refrigeration chamber 1121. This design allows for more precise delivery of cold air to each area, enabling independent temperature control of the refrigeration chamber 1121 and the variable temperature chamber 1122, thereby improving temperature stability. Because the second and third air duct sections 145, 146 abut one adjacent end and are both connected to the second liner 112, this layout fully utilizes space and reduces unnecessary waste.

[0075] The variable temperature air outlet duct 142 is arranged through the second air duct section 145, the refrigerated air outlet duct 141 is arranged through the second air duct section 145 and the third air duct section 146, and the variable temperature return air duct and the refrigerated return air duct are both arranged through the second air duct section 145. In this way, the entire air duct system is compact and the additional space occupied is reduced. This layout makes full use of the existing space and improves the space utilization rate of the storage device 100. In addition, this design can achieve independent control of the temperature of the refrigeration chamber 1121 and the variable temperature chamber 1122. This design makes the temperature regulation of each area more precise and can be flexibly adjusted according to the storage requirements of different foods. Since the air duct system is a modular design, the various air duct sections are relatively independent, so during maintenance and cleaning, a certain air duct section can be operated separately without disassembling the entire system. This greatly simplifies the maintenance process and improves maintenance efficiency.

[0076] It should be noted that, since the refrigerated air outlet duct 141 is provided through the second air duct portion 145 and the third air duct portion 146, Figure 1In an embodiment of the present application, a refrigeration damper is further provided between the second air duct portion 145 and the third air duct portion 146. The refrigeration damper is located within the refrigeration air outlet duct 141. The provision of the refrigeration damper allows for more precise temperature control of the refrigeration chamber 1121. By adjusting the opening degree of the refrigeration damper, the amount of cold air entering the refrigeration chamber 1121 can be effectively controlled, thereby ensuring that the temperature within the refrigeration chamber 1121 remains stable within a set range. The refrigeration damper can adjust the flow of cold air based on the actual needs of the refrigeration chamber 1121, avoiding waste of cold air. When the temperature of the refrigeration chamber 1121 reaches the set value, the opening degree of the refrigeration damper can be appropriately reduced to reduce the input of cold air, thereby saving energy. By adjusting the refrigeration damper, the noise and vibration generated by the flow of cold air can be reduced, improving the quietness of the storage device 100 and providing a more comfortable user environment. The second air duct portion 145 and the third air duct portion 146 are separately provided, which also makes the installation and maintenance operations of the refrigeration damper simple.

[0077] Reference Figure 5 and Figure 7 In one embodiment, the second air duct portion 145 and the second inner liner 112 are detachably connected via a first detachable structure. In this way, the detachable structure makes the connection between the second air duct portion 145 and the second inner liner 112 simple and quick. This not only saves time during the installation process, but also allows for easy disassembly when maintenance or replacement of parts is required, thereby improving work efficiency. When the second air duct portion 145 or the second inner liner 112 fails or needs to be upgraded, the detachable structure makes the repair or replacement process simple and convenient. There is no need to disassemble the entire storage device 100 on a large scale, only the problematic part needs to be operated, which greatly reduces the difficulty and cost of maintenance. The design of the detachable structure provides greater flexibility for the configuration of the storage device 100. The detachable structure makes it easy to replace and upgrade the second air duct portion 145, which means that when the second air duct portion 145 is damaged or outdated, the user only needs to replace some parts instead of the entire device, thereby reducing the cost of use. The detachable design makes it easier to reuse and recycle the second air duct portion 145 , which helps reduce waste generation and improve the environmental performance and sustainability of the equipment.

[0078] Reference Figure 5 and Figure 7In one embodiment, the third air duct portion 146 and the second inner liner 112 are detachably connected via a second detachable structure. In this way, the detachable structure makes the connection between the third air duct portion 146 and the second inner liner 112 simple and quick. This not only saves time during the installation process, but also allows for easy disassembly when maintenance or replacement of parts is required, thereby improving work efficiency. When the third air duct portion 146 or the second inner liner 112 fails or needs to be upgraded, the detachable structure makes the repair or replacement process simple and convenient. There is no need to disassemble the entire storage device 100 on a large scale, only the problematic part needs to be operated, which greatly reduces the difficulty and cost of maintenance. The design of the detachable structure provides greater flexibility for the configuration of the storage device 100. The detachable structure makes it easy to replace and upgrade the third air duct portion 146, which means that when the third air duct portion 146 is damaged or outdated, the user only needs to replace some parts instead of the entire device, thereby reducing the cost of use. The detachable design makes it easier to reuse and recycle the third air duct portion 146 , which helps reduce waste generation and improve the environmental performance and sustainability of the equipment.

[0079] Reference Figure 5 and Figure 7In one embodiment, the first detachable structure includes a first snap-fitting groove 161 and a first snap-fitting protrusion 162 adapted to the first snap-fitting groove 161. One of the first snap-fitting groove 161 and the first snap-fitting protrusion 162 is provided on the second air duct portion 145, and the other is provided on the inner wall surface of the second inner liner 112. In this way, the first snap-fitting groove 161 and the first snap-fitting protrusion 162 serve as quick connectors, making the connection process between the second air duct portion 145 and the second inner liner 112 extremely simple and efficient. During installation, the user only needs to align the first snap-fitting protrusion 162 with the first snap-fitting groove 161 and press lightly to fix it, without the need for additional tools or complicated operations. Similarly, when disassembly or adjustment is required, this structure also makes the process very easy, thereby saving the user's time and energy. The matching design of the first snap-fitting groove 161 and the first snap-fitting protrusion 162 ensures the stability of the connection. Once the first snap-fit ​​protrusion 162 is fully inserted into the first snap-fit ​​groove 161, the friction between them can prevent the air duct portion from shaking or falling off during operation, thereby ensuring the stability of the second air duct portion 145 and the sealing of the refrigerated air outlet duct 141. When any part of the second air duct portion 145 or the second inner liner 112 fails or needs to be upgraded, this detachable structure makes maintenance and replacement work simple. Maintenance personnel can quickly remove the faulty parts and then install new parts, thereby improving the maintenance efficiency of the equipment. Due to the detachable design, this structure makes the storage device 100 more flexible in configuration and use. According to different needs or scene changes, users can easily disassemble and reassemble the second air duct portion 145 to adapt to different airflow distribution requirements.

[0080] Reference Figure 5 and Figure 7In one embodiment, the second detachable structure includes a second snap-in groove 163 and a second snap-in protrusion 164 that mates with the second snap-in groove 163. One of the second snap-in groove 163 and the second snap-in protrusion 164 is located on the third air duct portion 146, and the other is located on the inner wall of the second inner liner 112. This design of the second detachable structure makes the connection between the third air duct portion 146 and the second inner liner 112 quick and easy. Installation is completed by simply aligning the second snap-in protrusion 164 with the second snap-in groove 163 and gently snapping it in. Disassembly is also very convenient; simply unscrew the snaps. This design significantly reduces the time and effort required for installation and disassembly. Through the tight connection between the second snap-in groove 163 and the second snap-in protrusion 164, the second detachable structure ensures a secure connection between the third air duct portion 146 and the second inner liner 112. This structure effectively prevents loosening or falling off during use, ensuring the overall stability and reliability of the third air duct portion 146. If the third air duct portion 146 malfunctions or requires upgrading, the second detachable structure makes maintenance and replacement simple and convenient. Users or maintenance personnel can easily remove the third air duct portion 146, perform necessary repairs or replacements, and then reinstall it. This significantly reduces maintenance complexity and costs.

[0081] Reference Figure 5 and Figure 7In one embodiment, a guide structure is further provided between the second air duct portion 145 and the second inner liner 112. The guide structure is located above the first detachable structure and includes a guide groove 171 extending in the vertical direction and a guide protrusion 172 adapted to the guide groove 171. One of the guide groove 171 and the guide protrusion 172 is provided on the second air duct portion 145, and the other is provided on the inner wall surface of the second inner liner 112. In this way, the cooperation between the guide groove 171 and the guide protrusion 172 enables the second air duct portion 145 and the second inner liner 112 to be quickly aligned during installation. The user or maintenance personnel only needs to align the guide protrusion 172 with the guide groove 171 and then install it along the direction of the guide groove 171 to ensure the correct connection between the components, greatly improving the accuracy and convenience of installation. The guide structure not only provides a guiding function during installation, but also increases the stability of the structure after the second air duct portion 145 is connected to the second inner liner 112. The close combination of the guide groove 171 and the guide protrusion 172 can effectively prevent the second air duct portion 145 from shaking or misaligning, thereby ensuring the stability and reliability of the entire storage device 100 during use. By providing a guide structure, direct collision and friction between components can be avoided during installation, reducing possible damage or scratches during installation, and extending the service life of the device. The guide structure can also play a role during disassembly or maintenance. Maintenance personnel can easily disassemble components along the direction of the guide groove 171 without excessive groping or adjustment, thereby improving the efficiency of maintenance work.

[0082] Reference Figure 2 and Figure 5In one embodiment, the fan assembly 150 includes an air supply tube 151 and a fan 152 installed in the air supply tube 151. The air supply tube 151 is installed between the first inner liner 111 and the second inner liner 112, and has an air inlet, a first air outlet, a second air outlet and a third air outlet. The air inlet is connected to the refrigeration cavity 1117, the first air outlet is connected to the freezing air inlet 128, and the second air outlet is connected to the refrigeration air inlet 1412. The third air outlet is connected to the variable temperature air inlet 1421. The fan 152 is used to draw cold air from the refrigeration chamber 1117 through the air inlet and discharge it through the first, second, and third air outlets. In this way, the fan assembly 150 achieves a highly efficient refrigeration effect by drawing cold air from the refrigeration chamber 1117 and discharging it through the first, second, and third air outlets to the freezer compartment 1118, the refrigerator compartment 1121, and the variable temperature chamber 1122. This design ensures that the freezer compartment 1118, the refrigerator compartment 1121, and the variable temperature chamber 1122 all receive sufficient cold air, thereby maintaining a low temperature environment within them and effectively extending the shelf life of food. Since the air supply tube 151 has an independent air inlet and the first air outlet, the second air outlet and the third air outlet, which are respectively connected to the refrigeration chamber 1117, the freezer chamber 1118, the refrigerator chamber 1121 and the variable temperature chamber 1122, each area can obtain appropriate cold air supply and realize temperature zoning control. This design not only meets the different temperature requirements of different areas, but also helps to improve energy utilization efficiency and reduce unnecessary energy consumption. The rotation of the fan 152 generates air flow, which promotes the circulation and uniform distribution of cold air in the refrigeration chamber 1117. This helps to eliminate temperature dead corners, ensure that food in every corner can be fully cooled, and improve the overall refrigeration effect. The air supply tube 151 is installed between the first inner liner 111 and the second inner liner 112, making full use of the space inside the box body 110 and making the overall design more compact. This design not only reduces the floor space, but also facilitates installation and maintenance.

[0083] Reference Figure 2The inner wall of the air supply duct 151 is equipped with multiple air storage slots 1511. These slots can store a certain amount of cold air when the fan 152 is operating and slowly release it when the fan 152 stops, thereby improving the efficiency of cold air storage and delivery. This design allows the cold air to be more evenly distributed to the freezer compartment 1118 and the refrigerator compartment 1121, avoiding direct impact of the cold air and drastic temperature fluctuations, thereby improving the cooling effect. The presence of the air storage slots 1511 ensures a smoother flow of cold air within the air supply duct 151, reducing airflow turbulence and energy loss. This allows the cold air to be more efficiently delivered to the freezer compartment 1118, the refrigerator compartment 1121, and the temperature-changing chamber 1122, improving the cooling effect. Furthermore, the air storage slots 1511 reduce temperature fluctuations caused by the start and stop of the fan 152, ensuring more stable temperature control. The air flow buffering effect of the air storage slots 1511 helps reduce noise and vibration generated by the fan 152, thereby improving the quietness of the device. This allows users to enjoy a quieter and more comfortable environment when using the refrigerator. The design of the air storage tank 1511 is usually combined with the structure of the air supply cylinder 151, making full use of the space inside the air supply cylinder 151. This design not only improves space utilization, but also makes the overall structure more compact and reasonable.

[0084] In one embodiment, the fan 152 includes a centrifugal fan. In this way, the centrifugal fan has a high energy efficiency ratio and can provide a relatively large air volume and pressure with low energy consumption. This means that it can more effectively suck in the cold air in the refrigeration cavity 1117 and transport it to the freezer compartment 1118, the refrigerator compartment 1121 and the variable temperature room 1122, ensuring that the temperature of these three areas is always maintained at the optimal state, thereby improving the refrigeration effect. The pressure output by the centrifugal fan can be adjusted according to actual application. Therefore, whether in the freezer compartment 1118 or the refrigerator compartment 1121, the centrifugal fan can provide a stable cold air circulation to meet the refrigeration needs of different areas. The centrifugal fan has the characteristics of simple structure and stable operation, and its noise and vibration are relatively small. This makes the storage device 100 quieter during operation and provides a more comfortable use environment.

[0085] The inner sidewall of the air supply duct 151 includes a first inner sidewall 1512, which is positioned opposite the centrifugal fan's air inlet. At least a portion of the multiple air storage slots 1511 are located within this first inner sidewall 1512. Placing the air storage slots 1511 within this first inner sidewall 1512 places them in close proximity to the centrifugal fan's air inlet. This allows the centrifugal fan to directly store some of the cold air in the air storage slots 1511 while drawing it in. The air storage slots 1511 not only increase the cold air storage capacity but also better retain and distribute the cold air within the air supply duct 151, improving its utilization. The air storage slots 1511 can store and slowly release cold air, resulting in a more even distribution of the cold air within the air supply duct 151. This helps reduce temperature fluctuations and dead spots, improving cooling uniformity within the freezer compartment 1118 and refrigerator compartment 1121, and ensuring better food preservation. By optimizing the coordination between the centrifugal fan, the first inner sidewall 1512, and the air storage tank 1511, energy loss during the intake and delivery of cold air is reduced. This design makes the entire refrigeration system more efficient, enabling more effective energy utilization and lowering operating costs.

[0086] Reference Figure 2 In one embodiment, each of the air storage slots 1511 provided on the first inner side wall 1512 is extended along the circumference of the air supply tube 151, so that the air storage slots 1511 form a continuous cold air storage space on the first inner side wall 1512 of the air supply tube 151. This design increases the capacity of the air storage slots 1511, so that more cold air can be stored in the air supply tube 151, so that the cold air can be released continuously and stably when needed. The design of the air storage slots 1511 extending in the circumferential direction makes the structure of the air supply tube 151 more stable. The circumferentially extending air storage slots 1511 can be realized by simple mold forming or processing during the manufacturing process, without the need for complicated processes and equipment. This helps to reduce manufacturing costs and improve production efficiency.

[0087] Reference Figure 2In one embodiment, at least a portion of the inner wall of each air storage slot 1511 is designed as a circular curved surface. This circular curved surface design makes the inner wall of the air storage slot 1511 smoother, reducing airflow resistance within the air storage slot 1511. As cold air flows through the air storage slot 1511, the circular curved surface guides the airflow more smoothly, reducing energy loss and improving the efficiency of the cold air flow. The circular curved inner wall surface better adapts to the flow characteristics of the airflow, enabling better storage and distribution of the cold air within the air storage slot 1511. This design helps reduce leakage and loss of cold air, ensuring rapid release when needed and improving storage efficiency. The circular curved surface design increases the pressure resistance of the inner wall of the air storage slot 1511, making it more durable and sturdy. This helps reduce structural deformation or damage caused by external pressure or vibration, thereby extending the service life of the air storage slot 1511. The relatively smooth inner wall surface of the circular curved surface is less likely to accumulate dust and dirt, making cleaning and maintenance easier and more convenient. This helps to keep the inside of the air storage tank 1511 clean and sanitary, ensuring the quality of the cold air and the cooling effect.

[0088] Reference Figure 2 In one embodiment, multiple air storage slots 1511 are spaced apart along the length of the air supply tube 151. This ensures a more even distribution of cold air within the air supply tube 151. Each air storage slot 1511 can store a certain amount of cold air and release it when needed. This ensures a uniform cooling effect across the entire length of the air supply tube 151, reducing temperature fluctuations and dead spots. The spaced-apart air storage slots 1511 can store and release cold air in sections, making the flow of cold air within the air supply tube 151 more orderly and efficient. This helps reduce cold air waste and energy loss, improves cooling efficiency, and enables the storage device 100 to reach and maintain the set temperature more quickly. The spaced-apart air storage slots 1511 simplify and facilitate the manufacturing and assembly of the air supply tube 151. Furthermore, during maintenance, each air storage slot 1511 can be easily inspected and cleaned, ensuring proper operation and cooling effectiveness.

[0089] Reference Figure 2In one embodiment, the outer wall surface of the air duct 151 is provided with reinforcing ribs 180, and the reinforcing ribs 180 are provided to extend in the circumferential direction. In this way, the main function of the reinforcing ribs 180 is to enhance the structural strength of the air duct 151 so that it can withstand greater pressure and stress. This is crucial to ensure that the air duct 151 maintains stable performance during long-term operation and in complex environments. Since there is often air flow and storage of cold air inside the air duct 151, this may cause it to deform. The provision of the reinforcing ribs 180 can effectively prevent the air duct 151 from being deformed due to internal pressure or external forces, and maintain the stability of its shape and function. The addition of the reinforcing ribs 180 improves the overall durability of the air duct 151, enabling it to better resist external impact and vibration, and reduce damage that may occur during use or transportation. The design of the reinforcing ribs 180 can also increase the surface area of ​​the outer wall of the air duct 151 to a certain extent, which helps to improve the heat dissipation effect and prevent the air duct 151 from overheating and affecting its performance and service life.

[0090] In one embodiment, multiple reinforcing ribs 180 are provided, spaced apart along the length of the air duct 151. By providing multiple reinforcing ribs 180 and spacing them along the length of the air duct 151, the air duct 151 is uniformly supported at all locations. This helps prevent excessive stress or deformation in specific locations of the air duct 151, thereby improving the stability and reliability of its overall structure. The provision of multiple reinforcing ribs 180 significantly increases the overall strength of the air duct 151. Each reinforcing rib 180 absorbs a portion of external forces. When the air duct 151 is subjected to external impact or pressure, the ribs 180 work together to effectively disperse and resist these forces, thereby protecting the air duct 151 from damage. The spaced-apart arrangement of the reinforcing ribs 180 not only provides structural support but also increases the outer surface area of ​​the air duct 151. This helps improve heat dissipation, allowing the air duct 151 to better dissipate heat generated during operation, preventing overheating that can affect performance and service life.

[0091] Reference Figure 2In one embodiment, the air supply tube 151 includes a first enclosing portion 1513 and a second enclosing portion 1514 arranged relative to each other in the front-to-back direction. The first enclosing portion 1513 and the second enclosing portion 1514 together enclose the air supply tube 151, and the first enclosing portion 1513 and the second enclosing portion 1514 are detachably connected. In this way, since the first enclosing portion 1513 and the second enclosing portion 1514 are detachably connected, the installation and removal process of the air supply tube 151 becomes simple and convenient. This design makes it easy to disassemble the air supply tube 151 when it needs to be repaired, replaced or cleaned, facilitating various operations. When a part of the air supply tube 151 fails or is damaged, due to the detachable connection design, only the faulty part can be replaced without replacing the entire air supply tube 151. This not only reduces maintenance costs, but also improves maintenance efficiency. The air supply tube 151 may accumulate dust or dirt during use, and the detachable connection design makes cleaning and maintenance work easier. The air supply cylinder 151 can be easily disassembled to allow for thorough cleaning of each part, ensuring it remains in good working condition. During transportation and storage, the air supply cylinder 151 can be disassembled into the first enclosure 1513 and the second enclosure 1514 to reduce the space it occupies. This not only facilitates transportation and storage, but also reduces transportation and storage costs.
