DETAILED DESCRIPTION

[0043] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used for the purpose of explanation only, and are not to be understood as limiting the present application.

[0044] The air-cooled refrigeration device drives the circulation of cold air for refrigeration by arranging evaporators, fans and other components in the air duct module. The vertical middle system refrigeration device places the air duct module in the middle of the refrigeration cavity. Although this design has significant advantages in terms of space saving and internal layout optimization, it also brings some new challenges. Due to the presence of evaporators, fans and other components, the temperature inside the air duct module is very low, which leads to the easy occurrence of condensation on the outside.

[0045] To address this problem, the conventional method is to add sponge material inside the air duct module to play a heat preservation role. The sponge material has good thermal insulation performance and can effectively reduce heat conduction, thereby preventing condensation on the outside of the air duct module. However, this method requires an additional process during production, making the manufacturing process of the partition more complex and increasing the manufacturing cost. Secondly, during installation and maintenance, the sponge material may be squeezed or damaged, affecting its heat preservation effect. In addition, its thermal insulation performance may gradually decrease, leading to the reoccurrence of condensation on the outside of the partition. Therefore, it is necessary to explore more efficient and convenient heat preservation solutions to further optimize the design and performance of the vertical middle system refrigerator.

[0046] Reference is made to Figures 1-9 The air duct module and the refrigeration device according to the embodiments of the present application are described.

[0047] Reference is made to Figure 1 The refrigeration device 1000 provided by the embodiments of the present application includes a cabinet 100, a door body 300, and an air duct module 200.

[0049] The cabinet 100 is provided with an inner container 110, and the inner container 110 forms a refrigeration cavity 111. The air duct module 200 is installed in the refrigeration cavity 111.

[0050] Reference is made to Figure 1The box 100 comprises an outer shell, an inner container 110 is arranged in the outer shell, and a thermal insulation layer is arranged between the outer shell and the inner container 110. The outer shell can be made of metal (such as steel plate), and the surface is treated by paint spraying to prevent rust and has a certain aesthetic appearance. The thermal insulation layer is located between the inner side of the outer shell and the inner container 110, can be polyurethane foam, has good heat insulation performance, can effectively prevent heat exchange between the inside and outside, and keep the internal temperature stable. The inner container 110 is a part directly contacting the stored objects, and is generally made of ABS plastic or stainless steel material, and is required to be non-toxic and easy to clean. An inner refrigeration cavity 111 for accommodating the stored objects is formed in the inner container 110.

[0051] A drawer can be arranged in the refrigeration cavity 111. The drawer is slidably installed in the refrigeration cavity 111, and helps users to store different types of stored objects by setting the drawer, thereby improving the use convenience. Independent temperature control can be set for different drawers to meet the best storage temperature of different foods. The drawer is usually detachable, and users can easily take out and clean it to maintain the hygiene of the inside of the refrigerator. The drawer is also convenient for setting various functional partitions, such as an egg shelf and a seasoning box, to facilitate users to store various small items.

[0052] The refrigeration cavity 111 can comprise a refrigeration chamber and a freezing chamber, or only one of the refrigeration chamber and the freezing chamber. The temperatures of different chambers are different, and the functions are different. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device arranged in or outside the box 100.

[0053] The door body 300 also comprises a three-layer structure of an outer shell, a thermal insulation material and an inner liner to ensure good sealing performance and thermal insulation effect. The door body 300 can be connected with the box 100 through a hinge structure to allow the door to open and close freely. The door body 300 can be a single door, or a double door, and the single door can also have a function of adjusting the opening direction left and right. A sealing strip can be installed at the edge of the door body 300, which is tightly attached to the box 100 to prevent cold air leakage, and cooperates with the box 100 to seal the refrigeration cavity 111.

[0054] The air duct module 200 is arranged in the refrigeration cavity 111.

[0055] The specific structure of the air duct module 200 can refer to the following technical solutions:

[0056] Please refer to Figure 1 and Figure 2 The embodiment of the present application also provides an air duct module 200, which comprises a shell 210, a decorative piece 220, a thermal insulation piece 240, a fan 230 and an evaporator 220.

[0057] The shell 210 is used to be installed in the refrigeration cavity 111, and the shell 210 is provided with a cavity 211, and the fan 230 and the evaporator 220 are installed in the cavity 211.

[0058] The cavity 211 in the shell 210 is used to circulate the cold air in the refrigeration cavity 111 and the cavity 211, and the cavity 211 is also used to accommodate the evaporator 220, the fan 230 and the gas return pipe and the like, and the shell 210 can be made of a metal material to have good mechanical strength and corrosion resistance, or can be made of a composite material to have good corrosion resistance, light weight and good thermal insulation, so as to not only reduce the weight of the entire air duct module 200, but also improve the heat preservation effect and reduce the energy consumption.

[0059] The fan 230 is used to drive the cold air to circulate in the refrigeration cavity 111 and the cavity 211, and the evaporator 220 is used to absorb heat to achieve the refrigeration effect, and the fan 230 and the evaporator 220 can be fixed in the shell 210 through the support to ensure the stability and reliability.

[0060] The decorative part 220 is arranged outside the cavity 211 and located on the side of the shell 210 close to the door body 300 of the refrigeration cavity 111, and the decorative part 220 is spaced from at least part of the shell 210 to form a heat preservation cavity 230, and the heat preservation part 240 is arranged in the heat preservation cavity 230.

[0061] One end of the refrigeration cavity 111 is open to facilitate the storage and taking of the stored objects, and the door body 300 is generally arranged at the open end of the refrigeration cavity 111 to cooperate with the cabinet 100 to seal the refrigeration cavity 111. Taking the refrigeration equipment 1000 as an example of a vertical side table, one side provided with the door body 300 is the front side, and the bottom in the depth direction of the refrigeration cavity 111 is the back side, and the decorative part 220 is arranged on the front side of the shell 210 to play a role in decorating and beautifying the external structure of the air duct module 200 and improving the appearance, and also plays a certain protection role. Among them, the decorative part 220 can also cooperate with the door body 300 to ensure the sealing of the refrigeration cavity 111 when the door body 300 is closed.

[0062] The decorative part 220 is spaced from at least part of the shell 210 to form a heat preservation cavity 230, because the decorative part 220 is arranged on the outside of the shell 210, so that the front side of the outside of the cavity 211 is formed with a heat preservation cavity 230 reserved in advance, and the heat preservation cavity 230 is relatively independent of the cavity 211, and the heat preservation part 240 is arranged in the heat preservation cavity 230 to block the cold quantity in the cavity 211 from being transmitted to the surface of the decorative part 220, thereby reducing the probability of condensation on the surface of the decorative part 220.

[0063] The setting mode can reduce the difficulty of production assembly, and the influence of the components and air in the cavity 211 on the heat preservation piece 240 is small. After the heat preservation piece 240 is set, the heat preservation piece 240 has high durability, and the overall durability of the equipment is improved. Moreover, the heat preservation piece 240 is located in the heat preservation cavity 230 on the outer side, and the decoration piece 220 can be opened to perform maintenance and replacement, thereby further reducing the maintenance cost in the later period.

[0064] According to the air duct module 200 provided by the embodiment of the present application, the heat preservation cavity 230 is reserved on one side of the cavity 211 close to the door body 300, and the heat preservation piece 240 is arranged in the heat preservation cavity 230, so as to block the cold quantity in the cavity 211 from being transmitted to the surface of the decoration piece 220, thereby reducing the probability of condensation on the surface of the decoration piece 220, and the heat preservation effect is better. Moreover, the heat preservation piece 240 is simply arranged by reserving the heat preservation cavity 230, the operation difficulty is low, the production efficiency is improved, and the overall durability is improved.

[0065] According to the refrigeration equipment 1000 provided by the embodiment of the present application, the heat preservation cavity 230 is reserved on one side of the cavity 211 close to the door body 300, and the heat preservation piece 240 is arranged in the heat preservation cavity 230, so as to block the cold quantity in the cavity 211 from being transmitted to the surface of the decoration piece 220, thereby reducing the probability of condensation on the surface of the decoration piece 220, and the heat preservation effect is better. Moreover, the heat preservation piece 240 is simply arranged by reserving the heat preservation cavity 230, the operation difficulty is low, the production efficiency is improved, and the overall durability is improved.

[0066] According to some embodiments of the present application, the heat preservation piece 240 can include heat preservation foam.

[0067] The heat preservation foam is a commonly used heat insulation material, which has the characteristics of light weight, low thermal conductivity, low water absorption rate, etc. Common heat preservation foam materials include polyurethane foam (PU foam), polystyrene foam (EPS foam), etc.

[0068] In the production process, the heat preservation foam can be pre-formed into the required shape, and then fixed in the heat preservation cavity 230. Pre-forming can simplify the installation process and improve production efficiency. In assembly, an environmentally friendly adhesive can be used to fix the heat preservation foam in the heat preservation cavity 230. The selection of the adhesive should consider its temperature resistance and aging resistance to ensure that the heat preservation foam does not fall off during long-term use.

[0069] By filling the heat preservation foam in advance, the heat preservation foam is used for heat preservation. This operation pre-installs the heat preservation foam in the space before the refrigerator is foamed, has good heat preservation effect, and can reduce the difficulty of foaming.

[0070] Please refer to Figure 3 and Figure 4According to some embodiments of the present application, the thermal insulation part 240 can comprise a thermal insulation foam, and the thermal insulation cavity 230 can extend in the height direction, and two ends of the thermal insulation cavity 230 in the height direction can be respectively provided with a first filling opening 231 and a second filling opening 232 which are in communication with the two ends.

[0071] The thermal insulation foam is a kind of porous material formed by chemical reaction or physical method, and has excellent thermal insulation performance. Common thermal insulation foams include polyurethane foam (PU foam), polystyrene foam (EPS foam), etc.

[0072] The thermal insulation cavity 230 extends in the height direction, and the two ends of the thermal insulation cavity 230 in the height direction are respectively provided with the first filling opening 231 and the second filling opening 232. Since the thermal insulation cavity 230 is long and narrow, separate injection at one end can easily lead to uneven foaming, affecting the thermal insulation effect. By providing two filling openings to inject foam raw materials into the thermal insulation cavity 230, it is ensured that the foaming process is uniform.

[0073] In actual implementation, the foam raw materials can be injected through the first filling opening 231, and the raw materials gradually foam and expand in the thermal insulation cavity 230 until the entire thermal insulation cavity 230 is filled. In order to ensure uniform foaming, the second filling opening 232 can be used for supplementing materials or exhausting gas to remove excess gas and unreacted raw materials. The first filling opening 231 and the second filling opening 232 can also be used to inject foam raw materials into the thermal insulation cavity 230 at the same time, and an exhaust hole can be arranged in the middle of the thermal insulation cavity 230. In addition, the entire air duct module 200 can be simultaneously foamed and filled while the entire box body 100 is foamed, which not only simplifies the operation process, but also significantly improves the thermal insulation effect.

[0074] According to the embodiments of the present application, the thermal insulation part 240 comprises a thermal insulation foam, and the design of the reserved thermal insulation cavity 230 (foaming space) and the two filling holes makes the foaming process more efficient and accurate. The operator only needs to inject the foaming agent at the specified position, and the foaming agent will uniformly fill the entire interior of the bulkhead, forming a dense thermal insulation layer. This integrated foaming process reduces additional processes, reduces production complexity and time cost. And the foaming agent is uniformly distributed in the interior of the bulkhead, forming a continuous thermal insulation layer, effectively blocking heat conduction, preventing cold air leakage and hot air intrusion.

[0075] Please refer to Figure 3 According to some embodiments of the present application, the first filling opening 231 can be arranged at the upper end of the thermal insulation cavity 230 and located between the shell 210 and the decorative part 220.

[0076] The first filling port 231 is arranged at the upper end of the heat preservation cavity 230, which helps the foaming material to flow downward naturally under the action of gravity, reduces the flow resistance, and ensures that the foaming material can uniformly fill the entire heat preservation cavity 230. In addition, the first filling port 231 is arranged between the shell 210 and the decorative piece 220, which can avoid opening holes on the shell 210 or the decorative piece 220, reduce the damage to the structure of the shell 210 and the decorative piece 220, and maintain the integrity and strength of the shell 210 and the decorative piece 220. The decorative piece 220 can also play a shielding role, making the filling port inconspicuous and maintaining the aesthetic appearance of the product.

[0077] Referring to Figure 4 According to some embodiments of the present application, the second filling port 232 is arranged at the lower end of the heat preservation cavity 230 and located at the lower end of the shell 210.

[0078] By arranging the second filling port 232 at the lower end of the heat preservation cavity 230 and at the lower end of the shell 210, the foaming material is injected from the lower end, which can utilize the buoyancy of air to naturally discharge air from the upper end of the heat preservation cavity 230, reduce the formation of bubbles and cavities, and reduce the dead angle reserved at the bottom of the heat preservation cavity 230.

[0079] The second filling port 232 is arranged in a spaced manner with the decorative piece 220, and the bottom of the shell 210 is provided with a protrusion near one end of the decorative piece 220, which is used for cooperating with the inner container 110 to play an auxiliary fixing role. The second filling port 232 is arranged completely at the bottom of the shell 210 to avoid affecting the fixation of the air duct module 200.

[0080] According to some embodiments of the present application, the heat preservation piece 240 can include heat preservation foam and heat preservation foaming, which can be distributed along the height direction, and the height of the heat preservation foam can be not less than half of the height of the heat preservation cavity 230.

[0081] For the heat preservation cavity 230, a part of the space is first filled with heat preservation foam, and the remaining part of the space can be simultaneously foamed and filled when the whole refrigeration equipment 1000 is foamed, so as to achieve the effect of double-layer heat preservation of heat preservation foam and foaming. The combination of heat preservation foam and heat preservation foaming can provide better heat insulation effect. The heat preservation foam usually has a low thermal conductivity, and the heat preservation foaming can provide good filling and sealing properties, which can effectively improve the anti-condensation effect of the outer side of the decorative piece 220.

[0082] The height of the heat preservation foam is not less than half of the height of the heat preservation cavity 230, which can ensure that the heat preservation foam occupies a larger space, further improves the heat insulation effect, and reduces the filling difficulty of the heat preservation foaming, thereby improving the production efficiency and heat preservation effect. For example, the height of the heat preservation foam can be 1 / 2, 3 / 5, 2 / 3, 3 / 4 or other proportion not less than 1 / 2 of the height of the heat preservation cavity 230, and the specific proportion is not limited.

[0083] In an example, the heat preservation foam can be arranged on the lower side of the heat preservation cavity 230, and the heat preservation foaming can be arranged on the upper side of the heat preservation cavity 230 and filled and foamed through the first filling port 231.

[0084] In another example, the heat preservation foam can be arranged on the upper side of the heat preservation cavity 230, and the heat preservation foaming can be arranged on the lower side of the heat preservation cavity 230 and filled and foamed through the second filling port 232.

[0085] In addition, this design also has better structural stability. The heat preservation foam or foaming filled in the heat preservation cavity 230 not only plays a heat preservation role, but also enhances the overall strength of the air duct module 200, so that it is not easy to deform or damage in long-term use, thereby further improving the durability and reliability of the refrigeration equipment 1000.

[0086] Referring to Figure 2 , Figure 5 and Figure 6 , according to some embodiments of the present application, at least one of the decoration piece 220 and the shell 210 towards the side of the heat preservation cavity 230 can be provided with a limiting part 223.

[0087] By providing the limiting part 223 on the decoration piece 220 and / or the shell 210, the heat preservation piece 240 in the heat preservation cavity 230 can be limited, which can ensure the accurate positioning of the heat preservation piece 240 during assembly, prevent mispositioning or displacement, and enhance the installation stability of the heat preservation piece 240.

[0088] For example, the limiting part 223 can include a protrusion arranged on the decoration piece 220, and the side of the decoration piece 220 towards the shell 210 is provided with a plurality of protrusions distributed along the height direction, and the surface of the heat preservation piece 240 towards the heat preservation piece 240 side matches the shape of the decoration piece 220.

[0089] Referring to Figure 2 , according to some embodiments of the present application, the side of the shell 210 close to the decoration piece 220 is provided with a heat preservation groove 212, and the decoration piece 220 is arranged at the opening of the heat preservation groove 212 to form the heat preservation cavity 230.

[0090] The heat preservation groove 212 is arranged on the outer side of the shell 210, so that the side wall and the bottom wall of the heat preservation groove 212 can constitute three side walls of the heat preservation cavity 230, the integrated structure is more stable, the stability of the heat preservation piece 240 is improved, the decorative piece 220 is arranged at the opening of the heat preservation groove 212, the structure of the decorative piece 220 can be simplified, the assembly and production of the decorative piece 220 are facilitated, and the production cost is reduced.

[0091] Please refer to Figure 2 、 Figure 5 and Figure 6 According to some embodiments of the present application, the decorative piece 220 can include a decorative plate 222 and a connecting plate 221, the connecting plate 221 can be connected with the shell 210, and the decorative plate 222 can be installed on the side of the connecting plate 221 away from the shell 210.

[0092] The decorative plate 222 mainly plays an aesthetic role, and can improve the appearance grade of the product, and the connecting plate 221 mainly plays a connecting and fixing role, so that the decorative plate 222 is firmly installed on the shell 210.

[0093] Specifically, the side wall of the heat preservation groove 212 can be provided with a connecting groove 2121, the connecting plate 221 can be provided in a groove type with an opening on one side, the groove opening of the connecting plate 221 can be arranged opposite to the groove opening of the heat preservation groove 212, and the two sides of the connecting plate 221 are provided with guide grooves 2211 which are in clamping connection with the side wall of the heat preservation groove 212, the side wall of the heat preservation groove 212 can be in plug-in connection with the guide grooves 2211, so as to play a guiding and limiting role when the connecting plate 221 is assembled, and the clamping convexes 2212 can be in clamping connection with the connecting grooves 2121, so as to ensure that the connecting plate 221 is stably connected with the side wall of the heat preservation groove 212. The guide grooves 2211 can play a role of fixing the heat preservation piece 240.

[0094] Please refer to Figure 7 、 Figure 8 and Figure 9 According to some embodiments of the present application, the air duct module 200 is connected with the inner container 110 at two ends in the height direction, the heat preservation piece 240 includes heat preservation foaming, the heat preservation cavity 230 extends in the height direction, and the heat preservation cavity 230 is provided with a first filling opening 231 and a second filling opening 232 which are in communication with the heat preservation cavity 230 at two ends in the height direction; the inner container 110 can be provided with a first opening 112 at a position corresponding to the first filling opening 231, and a second opening 113 at a position corresponding to the second filling opening 232.

[0095] By setting the first opening 112 and the second opening 113 on the inner container 110, the heat preservation foam can still be filled into the heat preservation cavity 230 through the first opening 112 and the second opening 113 when the air duct module 200 is assembled in the inner container 110. Moreover, when the entire refrigeration equipment 1000 is foamed, the foaming agent can also enter the heat preservation cavity 230 through the first opening 112 and / or the second opening 113, so that the middle partition plate can be synchronously foamed and filled while the entire box body 100 is foamed, thereby simplifying the operation process.

[0096] According to some embodiments of the present application, the thickness W of the refrigeration equipment 1000 in the depth direction of the refrigeration cavity 111 can satisfy 450mm≤W≤600mm.
