[0040] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] The following is for reference. Figures 1-7 This application describes an air duct module and a refrigeration device according to embodiments thereof.

[0042] Please see Figure 1 This application provides a refrigeration device 1000, which includes a housing 100, a door, and an air duct module 200.

[0043] The refrigeration equipment 1000 provided in this application embodiment can be a sideboard, refrigerator, freezer, or wine cabinet, etc., and is not specifically limited.

[0044] Please see Figure 1 The cabinet 100 includes an outer shell, an insulation layer, and an inner liner 110. The outer shell can be made of metal (such as steel plate), with a painted surface to prevent rust and for aesthetic purposes. The insulation layer, located between the inner shell and the inner liner 110, is made of polyurethane foam, providing excellent thermal insulation to effectively prevent heat exchange and maintain a stable internal temperature. The inner liner 110 is the part that directly contacts the stored items and is generally made of ABS plastic or stainless steel. It must be non-toxic and easy to clean. The interior of the inner liner 110 forms a cooling cavity for accommodating the stored items.

[0045] Drawers can be installed inside the refrigeration chamber. These drawers can slide inside the refrigeration chamber, allowing users to separate different types of items for easier storage and improving convenience. Independent temperature control can also be set for different drawers to meet the optimal storage temperature for different foods. Drawers are usually removable, allowing users to easily remove them for cleaning and maintain the hygiene of the refrigerator's interior. Drawers also facilitate the creation of various functional partitions, such as egg racks and spice containers, making it convenient for users to store various small items.

[0046] The refrigeration chamber may include a refrigerator compartment and a freezer compartment, or only one of the two. The different compartments have different temperatures and functions. The different temperature ranges of the refrigerator compartment and the freezer compartment can be adjusted by a temperature control device set inside or outside the cabinet 100.

[0047] The door also comprises a three-layer structure: an outer shell, insulation material, and an inner lining, ensuring excellent sealing and insulation performance. The door is connected to the enclosure 100 via hinges, allowing for smooth opening and closing. The door can be a single or double door; a single door can also have an adjustable opening direction. Sealing strips can be installed along the edges of the door, fitting snugly against the enclosure 100 to prevent cold air leakage and seal the refrigeration chamber.

[0048] The air duct module 200 is located inside the cooling cavity.

[0049] The specific structure of the air duct module 200 can refer to the following technical solution:

[0050] Please see Figures 1 to 5 This application embodiment also provides an air duct module 200, which includes a housing 210, a fan 240 and an evaporator 220.

[0051] The housing 210 is used to be installed in the cooling chamber and connected to the rear wall 112 of the cooling chamber. The housing 210 has a cavity for gas flow. One end of the housing 210 connected to the rear wall 112 has a lateral air outlet 2144. The air outlet 2144 is set at an angle to both the housing 210 and the rear wall 112.

[0052] Please see Figure 2 and Figure 3 The housing 210 has a cavity for gas flow, which can be used as part of the air duct. The cavity is also used to accommodate devices and pipelines such as the evaporator 220, the fan 240 and the return air pipe. The housing 210 can be made of metal materials to have good mechanical strength and corrosion resistance, or it can be made of composite materials to have good corrosion resistance, light weight and good heat insulation. This can not only reduce the weight of the entire air duct module 200, but also improve the heat insulation effect and reduce energy consumption.

[0053] The fan 240 and evaporator 220 are installed inside the cavity. The fan 240 is used to drive cold air to circulate within the refrigeration chamber and the cavity, thereby improving refrigeration efficiency. The evaporator 220 is used to absorb heat and achieve the refrigeration effect. The fan 240 and evaporator 220 can be fixed inside the housing 210 by a bracket to ensure their stability and reliability.

[0054] Please see Figure 4 and Figure 5 ,in, Figure 5The dotted lines in the diagram are a simplified illustration of the airflow direction and do not represent the actual direction of cold air flow. Taking the refrigeration unit 1000 as a vertical sideboard as an example, the rear wall 112 of the refrigeration chamber is the same as the rear wall 112 of the inner liner 110, which is also the side wall at one end in the depth direction of the refrigeration chamber, and this rear wall 112 extends along the height direction. The end of the housing 210 that connects to the rear wall 112 is provided with a laterally extending air outlet 2144. The air outlet 2144 is located at the rear end of the housing 210 and at the rear end of the corresponding side of the refrigeration chamber. By placing the air outlet 2144 in the corner of the refrigeration chamber, the occupancy of the refrigeration chamber depth is reduced. In the case of drawers inside the refrigeration chamber, interference with the drawers can be reduced, thereby increasing the effective volume of the drawers and improving storage space.

[0055] The air outlet 2144 is angled to both the housing 210 and the rear wall 112, meaning its airflow direction is tilted and directed towards the center of the cooling cavity. This allows the air outlet 2144 to circulate better within the cooling cavity, improving cooling efficiency and ensuring optimal cooling performance. Specifically, taking the housing 210 located on the right side of the cooling cavity as an example, the air outlet 2144 is positioned to the right rear of the cooling cavity, directing its airflow towards the left front of the cavity. This ensures the cold air from the air outlet 2144 diffuses diagonally across the cooling cavity, resulting in a more uniform temperature distribution and improved cooling effect.

[0056] Furthermore, the air outlet 2144 is located close to the housing 210, which shortens the flow path of the air supply channel inside the housing 210, increases the air supply speed, and also reduces the volume and number of structural components that extend the air outlet 2144 to the middle of the cooling cavity, thereby reducing the manufacturing cost and difficulty of the structural components.

[0057] According to the air duct module 200 provided in the embodiments of this application, by setting the air outlet 2144 at the end where the housing 210 is connected to the rear wall 112, the air outlet 2144 is located in the corner of the refrigeration cavity, which reduces the impact of the air outlet 2144 on the drawer and increases the volume of the drawer. In addition, the air outlet 2144 is inclined so that the cold air can be better guided to the middle of the refrigeration cavity, thereby ensuring the circulation effect of the cold air in the refrigeration cavity and ensuring the refrigeration effect.

[0058] Please see Figure 4 According to some embodiments of this application, the air outlet 2144 may be adapted to be misaligned with the projection of the first surface of the drawer near the rear wall 112 in the depth direction of the cooling cavity.

[0059] Understandably, the first surface of the drawer closest to the rear wall 112 is the part of the drawer closest to the air outlet 2144. The drawer typically moves along the depth direction of the cooling chamber. When in use, the drawer moves closer to or further away from the rear wall 112 along the depth direction of the cooling chamber. When the drawer is in its retracted state, the first surface is closest to the rear wall 112. By setting the air outlet 2144 to be offset from the projection of the first surface along the depth direction of the cooling chamber, even when the drawer is closest to the rear wall 112, the first surface will not contact the air outlet 2144. This prevents the air outlet 2144 from directly occupying the drawer's space, reducing its impact on the drawer and increasing its effective volume. Furthermore, the air outlet 2144 will not obstruct the normal opening and closing of the drawer, improving the user's storage space and user experience.

[0060] Specifically, taking the top of the drawer being open as an example, the air outlet 2144 can be located on the top of the first surface so that the air blown out by the air outlet 2144 can enter the corresponding drawer and cool the stored items inside the drawer.

[0061] Please see Figure 5 and Figure 6 According to some embodiments of this application, the housing 210 may include a rear plate 214 for connection with the rear wall 112. The side of the rear plate 214 may be provided with a laterally extending air duct 2143. The side of the air duct 2143 away from the rear wall 112 is open to form an air outlet 2144.

[0062] Taking the refrigeration equipment 1000 as an example of a vertical sideboard, the side with the door is the front side, and the bottom of the refrigeration cavity in the depth direction is the rear side. The back plate 214 of the shell 210 is used to connect with the rear wall 112, which can play the role of fixing the entire shell 210.

[0063] The side of the rear panel 214 may be provided with a laterally extending air supply duct 2143. It is understood that the air supply duct 2143 communicates with the cavity, allowing the cold air inside the cavity to be delivered to the air supply duct 2143. By providing the air supply duct 2143, at least a portion of the air outlet 2144 can extend into the cooling cavity, facilitating adjustment of the air supply direction and improving airflow into the cooling cavity. The side of the air supply duct 2143 facing away from the rear wall 112 is open to form the air outlet 2144, which is positioned towards the center of the cooling cavity. This design uses less material and has low airflow resistance, promoting the circulation of cold air within the cooling cavity.

[0064] Please see Figure 5 , Figure 6 and Figure 7According to some embodiments of this application, the end of the air supply duct 2143 away from the rear plate 214 may be provided with a first guide slope 1111, the first guide slope 1111 is inclined in the direction away from the rear wall 112 along the air outlet direction, and the end of the air outlet 2144 near the rear plate 214 may be provided with a second guide slope 2162, the second guide slope 2162 is inclined in the direction away from the rear wall 112 along the air outlet direction.

[0065] It is understandable that the end of the air supply duct 2143 near the rear plate 214 is the air inlet, and the end away from the rear plate 214 is the air outlet. By setting a first guide slope 1111 at the end of the air supply duct 2143 away from the rear plate 214, the air supply direction is guided. When the cold air reaches the air outlet of the air supply duct 2143, it is tilted and delivered under the action of the first guide slope 1111. The first guide slope 1111 is tilted away from the rear wall 112 along the air outlet direction, that is, tilted towards the middle of the refrigeration cavity where the air supply duct 2143 is located, so as to guide the cold air to the middle of the refrigeration cavity where it is located and blow it in a diagonal direction.

[0066] The air outlet 2144 is provided with a second guide slope 2162 at one end near the rear plate 214. That is, the air outlet 2144 is also provided with a guide slope on the side near the air inlet end of the air supply pipe 2143. The second guide slope 2162 works in conjunction with the first guide slope 1111 so that the cold air can be blown better in the target direction after entering the air supply pipe 2143, reducing the air outlet resistance, improving the air supply efficiency, and facilitating accurate control of the air supply direction.

[0067] Please see Figure 5 , Figure 6 and Figure 7 According to some embodiments of this application, the housing 210 further includes a first side plate 211 and a second side plate 212 disposed opposite to each other, and a second guide slope 2162 is disposed on the first side plate 211 and / or the second side plate 212.

[0068] The housing 210 may include a first side plate 211 and a second side plate 212 spaced apart from each other, with the first side plate 211 and the second side plate 212 spaced apart along the thickness direction of the housing 210. The housing 210 may also include a front plate 213. Taking the refrigeration equipment 1000 as a vertical sideboard as an example, the side with the door is the front side, and the bottom of the refrigeration cavity in the depth direction is the rear side. The rear plate 214 is used to connect with the rear wall 112. The front plate 213 is located on the side close to the door. The first side plate 211 and the second side plate 212 are distributed in the left and right direction. The left and right ends of the front plate 213 are respectively connected to the front ends of the first side plate 211 and the second side plate 212. The left and right ends of the rear plate 214 are respectively connected to the rear ends of the first side plate 211 and the second side plate 212, so as to enclose and form a cavity for accommodating devices such as the evaporator 220 and the fan 240.

[0069] When the housing 210 is installed on one side of the cooling cavity in the width direction, one of the first side plate 211 and the second side plate 212 is connected to the side wall of the cooling cavity, and the other is set towards the cooling cavity. The air supply pipe 2143 is set on the side facing the cooling cavity. Specifically, when the first side plate 211 faces the cooling cavity, the air supply pipe 2143 is set on the side of the rear plate 214 close to the first side plate 211. At this time, the second guide slope 2162 is set on the first side plate 211 and corresponds to the air supply port 2144. When the second side plate 212 faces the cooling cavity, the air supply pipe 2143 is set on the side of the rear plate 214 close to the second side plate 212. At this time, the second guide slope 2162 is set on the second side plate 212 and corresponds to the air supply port 2144.

[0070] Please see Figure 1 and Figure 4 According to some embodiments of this application, the housing 210 can be disposed in the middle of the cooling cavity to divide the cooling cavity into a first chamber 120 and a second chamber 130, and multiple air outlets 2144 are provided on both sides of the housing 210.

[0071] The housing 210 can be positioned in the middle of the cooling chamber as a partition. Taking the housing 210 positioned in the middle of the cooling chamber's width as an example, the housing 210 can divide the cooling chamber along its width into a first chamber 120 and a second chamber 130 that are spaced apart. Air outlets 2144, corresponding to the first chamber 120 and the second chamber 130, are respectively provided on both sides of the housing 210 to supply air to the first chamber 120 and the second chamber 130, thereby simultaneously cooling both chambers. The temperature of the first chamber 120 and the second chamber 130 can be controlled by adjusting the airflow through the air outlets 2144 on both sides. The temperatures of the first chamber 120 and the second chamber 130 can be the same or different, without specific limitation.

[0072] Taking the first side plate 211 on the left and the second side plate 212 on the right as an example, the first side plate 211 corresponds to the first chamber 120 and the second side plate 212 corresponds to the second chamber 130. Since air needs to be supplied to the first chamber 120 and the second chamber 130 respectively, air supply pipes 2143 and air outlets 2144 can be provided on both sides of the rear plate 214. At this time, the first side plate 211 and the second side plate 212 are provided with second guide slopes 2162 on opposite sides, and the second guide slopes 2162 on the two side plates correspond to the air outlets 2144 on both sides respectively.

[0073] It is understandable that the air supply duct 2143 extends to the outside of the first side plate 211 or the second side plate 212 so that the second guide slope 2162 provided on the first side plate 211 or the second side plate 212 can guide the airflow delivered by the air supply port 2144.

[0074] Please see Figure 4 and Figure 6 According to some embodiments of this application, the rear plate 214 may be provided with an air supply duct 2141 extending along the height direction, and multiple air supply pipes 2143 may be provided distributed along the height direction. All multiple air supply pipes 2143 are connected to the air supply duct 2141, and the length of at least one air supply pipe 2143 is different from the length of air supply pipes 2143 located at other heights.

[0075] An air duct 2141 extending along the height direction is provided within the rear panel 214 to ensure that the cold air can be evenly distributed at different height positions, thereby improving the cooling effect. The air duct 2141 is connected to the cavity, and the fan 240 operates to deliver air from the cavity into the air duct 2141. The air duct 2141 is also connected to the air supply pipe 2143, so that the cold air in the air duct 2141 can be blown out through the air outlet 2144 on the air supply pipe 2143. It should be noted that both ends of the housing 210 in the height direction are connected to the top and bottom walls of the refrigeration cavity, so that the air duct 2141 can cover all positions of the refrigeration cavity in the height direction as much as possible.

[0076] Multiple air supply ducts 2143 can be provided along the height direction, that is, multiple air outlets 2144 can be provided along the height direction. Multiple air supply ducts 2143 can be arranged at intervals along the height direction, which can make the cold air evenly distributed at different height positions, improve the efficiency of gas flow, improve the uniformity of temperature in the refrigeration cavity, and ensure the refrigeration effect at each position.

[0077] The number of air supply ducts 2143 in the height direction is not specifically limited. It can be two, three, four or more. It can be set according to the airflow organization or determined according to the number of compartments in the refrigeration chamber. For example, if there are three drawers in the refrigeration chamber, there can be three air supply ducts 2143 distributed along the height direction, and the three air supply ducts 2143 correspond to the three drawers respectively.

[0078] It should be noted that the opening size of the air outlet 2144 determines its flow area to a certain extent. A larger flow area results in lower resistance, thus allowing for adjustment of the air volume distributed to the corresponding air outlet 2144. Because the air outlet 2144 is located on the side of the air supply duct 2143 away from the rear wall 112, the length of the air supply duct 2143 determines the size of the air outlet 2144. Furthermore, the air pressure at different positions along the height of the air supply duct 2141 will inevitably differ. By setting at least one air supply duct 2143 with a different length than those at other heights, i.e., at least one air outlet 2144 has a different flow area than those at other heights, the air volume of multiple air outlets 2144 can be adjusted. This allows the air volume of multiple air outlets 2144 to be approximately the same, or the air volume of each air outlet 2144 to be different, thereby accurately regulating the temperature distribution within the cooling cavity.

[0079] Please see Figure 4 In some embodiments, the air supply duct 2143 may be provided in three parts distributed along the height direction, with the upper air supply duct 2143 having the longest length.

[0080] Generally, the longer the air supply duct 2143 is, the larger the flow area of ​​the air supply outlet 2144 is, and the greater the corresponding output air volume is.

[0081] The upper air outlet 2144 is positioned near the top of the cooling chamber where the air duct module 200 is located. This design likely ensures stronger airflow in the top area, thereby achieving a better cooling effect. Specifically, in the cooling equipment 1000, the temperature at the top is usually higher than at the bottom because cold air sinks and hot air rises, creating a significant temperature gradient. The maximum airflow from the upper air outlet 2144 can more effectively capture and displace the hot air accumulated at the top, thus accelerating air circulation throughout the inner liner 110. This helps reduce the temperature gradient in the top area, ensuring a more uniform temperature throughout the inner liner 110. Furthermore, during the cooling process, the cold air at the top is prone to condensation. The maximum airflow from the upper air outlet 2144 accelerates the flow of cold air, reducing condensation accumulation. This helps keep the inside of the inner liner 110 dry, preventing moisture damage to internal components and items.

[0082] In some embodiments, the housing 210 has a first return air inlet 215 at the middle in the height direction, and the length of the air supply pipe 2143 located in the middle is less than the length of the air supply pipe 2143 located at the lower end.

[0083] Air in the cooling chamber can enter the cavity through the first return air inlet 215 and then be blown out through multiple air outlets 2144. The housing 210 has a first return air inlet 215 in the middle of the height direction. The return air position of the housing 210 is located at the middle height inside the inner liner 110, which can effectively recover the air in the middle and promote the vertical circulation of air.

[0084] Because the air supply vent 2144 located in the middle is closer to the first return air vent 215, by reducing the air volume of the air supply vent 2144 located in the middle and increasing the air volume of the air supply vent 2144 located at the lower end, the flow of gas at different heights can be optimized, ensuring that the cold air at the lower end can flow more effectively to the middle, reducing the temperature gradient and improving cooling efficiency.

[0085] Please see Figure 4 In some embodiments, the air outlets 2144 are provided in three pairs distributed along the height direction (when air outlets 2144 are provided on both sides of the housing 210, the ratio of the air volume of the three air outlets 2144 from top to bottom can be 5:2:3. Furthermore, the ratio of the flow area of ​​the three air outlets 2144 from top to bottom is also 5:2:3.

[0086] Please see Figure 7 According to some embodiments of this application, the inclination angles of the first guide slope 1111 and the second guide slope 2162 corresponding to at least one air supply duct 2143 are different.

[0087] The first guide ramp 1111 and the second guide ramp 2162, with different tilt angles, can optimize the flow direction of cold air according to the cooling requirements at different heights. For example, a larger tilt angle can be used where stronger airflow is needed, while a smaller tilt angle can be used where gentler airflow is needed. By adjusting the tilt angle of the guide ramps, the airflow resistance during cold air transmission can be reduced, improving air delivery efficiency. A larger tilt angle can reduce airflow resistance at bends, ensuring that cold air flows smoothly out of the air delivery duct 2143. Guide ramps with different tilt angles can better adapt to the cooling requirements at different heights, ensuring that cold air can be evenly distributed throughout the cooling chamber, thus improving the cooling effect.

[0088] For example, in Figure 7 In the middle, with the rear wall 112 as the reference plane, the inclination angle of the second guide slope 2162 corresponding to the air supply duct 2143 on the right side is greater than the inclination angle of the first guide slope 1111.

[0089] It is understandable that the inclination angles of the first guide slope 1111 and the second guide slope 2162 corresponding to the same air supply duct 2143 can be the same. Similarly, in Figure 7In the middle, with the rear wall 112 as the reference plane, the first guide slope 1111 and the second guide slope 2162 corresponding to the air supply pipe 2143 on the left side have the same inclination angle.

[0090] Please see Figure 6 and Figure 7 According to some embodiments of this application, air supply pipes 2143 can be provided on both sides of the rear plate 214, and multiple air supply pipes 2143 on both sides are arranged one-to-one in the height direction, and at least one pair of two second guide slopes 2162 corresponding in the height direction have different inclination angles.

[0091] By providing air supply pipes 2143 on both sides of the rear plate 214 to supply air to the first chamber 120 and the second chamber 130 located on both sides of the housing 210 respectively, the multiple air supply pipes 2143 located on both sides are arranged one-to-one along the height direction so that the cold air in the air supply duct 2141 is evenly distributed in the air supply ports 2144 on both sides, which facilitates the control of the temperature of the first chamber 120 and the second chamber 130.

[0092] At least one pair of second guide slopes 2162 corresponding in the height direction have different inclination angles. It can be understood that the second guide slopes 2162 are located near the air inlet end of the air supply duct 2143. By changing the inclination angle of the second guide slopes 2162, not only can the air outlet angle be changed, but also the air outlet resistance of the air outlet 2144 can be changed, thereby adjusting the air volume of the two air outlets 2144 located at the same height. When the air pressure on both sides of the air supply duct 2141 is uneven, it may lead to different air volumes at the two air outlets 2144. When it is necessary to make the temperature of the first chamber 120 and the second chamber 130 the same, the air volume of the air outlet 2144 can be adjusted by adjusting the flow area of ​​the air outlet 2144 and by adjusting the inclination angle of the second guide slopes 2162.

[0093] According to some embodiments of this application, the inclination angle of the first guide ramp 1111 located at different heights may be different, and / or the inclination angle of the second guide ramp 2162 located at different heights may be different.

[0094] With different lengths of air supply ducts 2143 at different heights, the positions of the ends of air outlets 2144 are also different, which in turn makes the starting point of the first guide slope 1111 different. When the air supply direction of the air outlet 2144 is set to face diagonally as the design basis, the inclination angles of the first guide slope 1111 and / or the second guide slope 2162 are also different for air supply ducts 2143 of different lengths, so that the air supply direction of air supply ducts 2143 of different lengths is facing diagonally.

[0095] Please see Figure 4 and Figure 7 According to some embodiments of this application, the rear wall 112 may be provided with a protrusion 111, the protrusion 111 being located at the end of the air supply pipe 2143 away from the housing 210, and the first guide slope 1111 being provided on the protrusion 111.

[0096] A protrusion 111 may be provided on the rear wall 112 of the cooling chamber, wherein the protrusion 111 may be integrated into the inner liner 110. The protrusion 111 is located at the end of the air supply pipe 2143 away from the housing 210, that is, at the air outlet end of the air supply pipe 2143. The air outlet end of the air supply pipe 2143 may be open so as to face the protrusion 111. The first guide slope 1111 is provided on the side of the protrusion 111 facing the air supply pipe 2143, so that the cold air blown out through the air supply pipe 2143 can be tilted under the action of the protrusion 111.

[0097] It should be noted that the air supply duct 2143 and the rear plate 214 can be integrally molded, for example, by injection molding. By opening the end and front of the air supply duct 2143, the molding difficulty of the structural components can be greatly reduced. By setting a separate protrusion 111 and setting the first guide slope 1111 on the protrusion 111, the structure of the air supply duct 2143 is simplified, thereby reducing the manufacturing difficulty of the air supply duct 2143. While playing a guiding role, it greatly reduces the overall production cost.

[0098] According to some embodiments of this application, the thickness H of the housing 210 in the width direction of the cooling cavity can satisfy: 55mm≤H≤85mm.

[0099] By limiting the thickness H of the housing 210, the housing 210 becomes ultra-thin, resulting in a compact internal space arrangement. The air duct module 200 does not occupy the thickness of the refrigeration equipment 1000, thus reducing the thickness of the refrigeration equipment 1000 and minimizing its impact on the internal space of the refrigeration chamber, thereby improving overall space utilization.

[0100] The thickness H of the housing 210 in the width direction of the cooling cavity is in the range of [55mm, 85mm]. For example, H can be 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm or other values ​​between 55mm and 85mm, without specific limitation.

[0101] According to some embodiments of this application, the thickness W of the refrigeration device 1000 in the depth direction of the refrigeration cavity can satisfy: 450mm≤W≤600mm.

[0102] The refrigeration equipment 1000 is relatively thin, which improves its aesthetics and allows it to better fit the user's interior decoration, thus enhancing product quality. Specifically, the thickness W of the refrigeration equipment 1000 in the depth direction of the refrigeration cavity ranges from [450mm, 600mm]. For example, W can be 450mm, 500mm, 550mm, 600mm, or other values ​​between 450mm and 600mm; no specific limitation is imposed.

[0103] According to some embodiments of this application, the thickness S of the door body can satisfy: 25mm≤S≤40mm.

[0104] The door of the refrigeration unit 1000 is relatively thin, making it lightweight and easy to open. This also reduces the impact on the overall thickness of the refrigeration unit 1000, allowing it to be made thinner for better integration with the user's interior decoration and improved product quality. The door thickness S ranges from [25mm, 50mm]. For example, S can be 25mm, 30mm, 35mm, 40mm, or other values ​​between 25mm and 40mm; no specific limitation is imposed.
