DETAILED DESCRIPTION

[0047] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only for explanation of the present application, and cannot be understood as limiting the present application.

[0048] Generally, a refrigerator places key components such as an evaporator and a fan at the back plate of the refrigerator. Although this traditional layout is mature, it also has certain limitations. Some refrigerators use an innovative design to place components such as the evaporator and the fan at the side plate of the refrigerator, or in the middle partition to form a vertical middle system refrigerator. One significant advantage of this design is that it can effectively reduce the thickness of the refrigerator, thereby saving kitchen space and improving the aesthetics and practicality of the refrigerator.

[0049] However, this layout also brings some technical challenges. Placing the evaporator and the return air pipe in the side plate or the middle partition is difficult due to the limited space and complex operation, which increases the difficulty of welding. In addition, this design also increases the difficulty of operation during subsequent maintenance, which is inconvenient and may prolong the maintenance time and increase the maintenance cost.

[0050] Based on the above considerations, the present application proposes an air duct module and a refrigeration equipment to reduce the difficulty of evaporator assembly and maintenance, and to facilitate operation and reduce production and maintenance costs.

[0051] Reference is made below to Figures 1-12 The air duct module and the refrigeration equipment according to the embodiments of the present application are described.

[0052] The embodiments of the present application provide a refrigeration equipment 1000, which includes a cabinet 100, a door body, and an air duct module 200.

[0053] The cabinet 100 is internally provided with a refrigeration cavity, and the air duct module is arranged in the middle part of the refrigeration cavity to form a refrigeration system.

[0054] The refrigeration equipment 1000 provided by the embodiments of the present application can be a side-by-side cabinet, a refrigerator, a freezer, or a wine cabinet, and the like, and the specific type is not limited.

[0055] Please refer to Figure 1 The cabinet 100 includes an outer shell, a thermal insulation layer, and an 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, and can be polyurethane foam, which has good heat insulation performance and can effectively prevent heat exchange between the inside and outside, thereby maintaining the internal temperature stable. The inner container 110 is the part directly contacting the stored objects, and can generally be made of ABS plastic or stainless steel material, which is required to be non-toxic and easy to clean. The inner container 110 has a refrigeration cavity formed therein for accommodating the stored objects.

[0056] The refrigeration cavity can include a refrigeration refrigeration cavity and a freezing refrigeration cavity, or only one of the refrigeration refrigeration cavity and the freezing refrigeration cavity. The temperatures of different chambers are different, and the functions are different. The different temperature ranges of the refrigeration refrigeration cavity and the freezing refrigeration cavity are adjusted by a temperature control device arranged in or outside the cabinet 100.

[0057] The door body also includes an outer shell, a thermal insulation material, and an inner lining, which ensures good sealing and thermal insulation effects. The door body can be connected to the cabinet 100 through a hinge structure, allowing the door to open and close freely. The door body 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, which tightly fits with the cabinet 100 to prevent cold air leakage and cooperates with the cabinet 100 to seal the refrigeration cavity.

[0058] Please refer to Figure 1 , Figure 2 and Figure 3 The air duct module 200 provided by the embodiments of the present application includes a shell 210, a fan 240, an evaporator 220, a return air pipe 250, and a window cover plate 260.

[0059] The shell 210 is provided with a cavity; the fan 240 and the evaporator 220 are arranged in the cavity; the return air pipe 250 is used to connect the compressor and the evaporator 220, and the shell 210 is provided with an operation window 2122 corresponding to the connection positions of the return air pipe 250 and the evaporator 220; and the window cover plate 260 is arranged outside the operation window 2122.

[0060] The shell 210 is internally provided with a cavity for gas circulation, which can be part of an air duct. The cavity is also used to accommodate devices and pipelines such as the evaporator 220, the fan 240, and the gas return pipe 250. The shell 210 can be made of metal material, which has good mechanical strength and corrosion resistance, or can be made of composite material, which has good corrosion resistance, light weight, and good thermal insulation. This not only reduces the weight of the entire air duct module 200, but also improves the heat preservation effect and reduces energy consumption.

[0061] The fan 240 and the evaporator 220 are respectively fixed in the cavity of the shell 210. The fan 240 is used to drive the circulation of cold air in the refrigeration cavity and the cavity, thereby improving the refrigeration efficiency. The evaporator 220 is used to absorb heat to achieve the refrigeration effect. The fan 240 and the evaporator 220 can be fixed in the shell 210 through a support to ensure their stability and reliability.

[0062] The gas return pipe 250 is used to connect the compressor and the evaporator 220, so that the refrigerant can circulate in the system. One end of the gas return pipe 250 is connected to the evaporator 220, and the other end passes through the shell 210 and is connected to the external compressor. The shell 210 is provided with an operation window 2122 corresponding to the connection position of the gas return pipe 250 and the evaporator 220. The size of the operation window 2122 is designed to be large enough to facilitate welding and maintenance operations by workers.

[0063] It can be understood that the gas return pipe 250 and the evaporator 220 are generally connected by welding. In the related art, the evaporator 220 and the cover plate covering the evaporator 220 are separate components, which are independently produced, transported, and assembled. During assembly, the evaporator 220 is first installed, then the evaporator 220 and the gas return pipe 250 are welded and connected, and then the cover plate is installed to cover the evaporator 220. This installation method has many components and low assembly efficiency. In the present scheme, the evaporator 220 is integrated in the shell 210 as a whole component for transportation, and the shell 210 and the evaporator 220 are directly assembled as a whole in the cabinet 100 during assembly. Workers can weld the connection position of the evaporator 220 and the gas return pipe 250 through the operation window 2122, without the need to disassemble the cover plate to complete the welding operation, thereby improving the assembly efficiency.

[0064] In addition, the operation window 2122 is provided with a window cover plate 260 for sealing the shell 210 to prevent cold air leakage. The window cover plate 260 is detachably fixed on the shell 210, and is very convenient to disassemble and install. When welding or maintenance is required at the connection position of the evaporator 220 and the gas return pipe 250, the window cover plate 260 can be simply disassembled.

[0065] In one example, a sealing strip may be provided around the operating window 2122 to further enhance the sealing performance of the housing 210 and prevent cold air leakage. The sealing strip may be made of elastic materials such as rubber or silicone, which have good sealing effect and durability.

[0066] In actual operation, the shell 210 is first integrated with the evaporator 220 and fan 240 and insulated with foam to form a whole. Then, the shell 210, evaporator 220, and fan 240 are installed and fixed inside the cabinet 100. The window cover 260 is opened, and the evaporator 220 is welded to the return air pipe 250, thus completing the assembly of the air duct module 200. Under normal operating conditions, the fan 240 drives cold air through the evaporator 220. The evaporator 220 absorbs heat, cooling the cold air, which then enters the refrigerator through the air duct module 200, achieving a cooling effect. When welding or maintenance is required at the connection between the evaporator 220 and the return air pipe 250, simply removing the window cover 260 allows for direct operation, greatly simplifying the welding and maintenance process and reducing production and maintenance costs.

[0067] According to the air duct module 200 of the present application embodiment, the evaporator 220 is disposed inside the housing 210 of the air duct module 200. By providing an operation window 2122 on the housing 210, during welding and maintenance, the connection between the evaporator 220 and the return pipe 250 can be welded or maintained simply by removing the window cover 260. The operation is simple and convenient, reducing production and maintenance costs.

[0068] The air duct module 200 is located in the middle of the cooling chamber, and the housing 210 divides the cooling chamber into a first chamber 120 and a second chamber 130. The housing 210 is located in the middle of the cooling chamber as a partition. Taking the housing 210 as being located in the middle of the width direction of the box 100 as an example, the housing 210 can divide the cooling chamber inside the box 100 into mutually spaced first chambers 120 and second chambers 130 along the width direction. Air outlets 2144 corresponding to the first chambers 120 and second chambers 130 are respectively provided on both sides of the housing 210 to supply air to the first chambers 120 and second chambers 130 to achieve the cooling effect. The temperature of the first chambers 120 and second chambers 130 can be the same or different, without specific limitation.

[0069] In one example, such as Figure 1 As shown, the housing 100 may be provided with a refrigeration chamber and a freezing chamber distributed in the vertical direction, and the air duct module 200 may be installed in the freezing chamber.

[0070] In actual implementation, taking the case of the air duct module 200 being arranged in the refrigeration cavity as an example, in the case of the entire refrigeration device 1000 being thinner in thickness, the air duct module 200 is arranged in the middle to facilitate air supply to the first chamber 120 and the second chamber 130 respectively, in the case of no temperature differentiation, the air volume of the first chamber 120 and the second chamber 130 can be controlled to be uniform, and the temperature uniformity of the entire refrigeration cavity is improved; in the case of temperature differentiation, the air volume of the first chamber 120 and the second chamber 130 can be controlled to be different, the storage space of multiple temperature intervals is realized, and the use convenience is improved.

[0071] According to the refrigeration device 1000 provided by the embodiments of the present application, by arranging the air duct module 200 in the middle of the refrigeration cavity, the temperature uniformity of the first chamber 120 and the second chamber 130 can be improved, and by distributing different air volumes to make the temperatures of the first chamber 120 and the second chamber 130 different, the use convenience is improved, the assembly is simple and efficient, the subsequent maintenance is convenient, and the assembly and maintenance costs are reduced.

[0072] Please refer to Figure 4 According to some embodiments of the present application, the edge of the operation window 2122 can be flush with the end of the evaporator 220 close to the return air pipe 250.

[0073] Taking the case of the return air pipe 250 being arranged at the upper end of the evaporator 220 as an example, the upper end of the evaporator 220 is connected with the return air pipe 250, and the lower edge of the operation window 2122 is flush with the upper end of the evaporator 220, when welding or maintenance is needed for the connection position of the evaporator 220 and the return air pipe 250, the worker can directly see and touch the connection point, so that the operation is more convenient. And, because the edge of the operation window 2122 is flush with the end of the evaporator 220, that is, the evaporator 220 is not exposed at the operation window 2122, the fins and pipelines of the evaporator 220 are protected to some extent, and the damage probability is reduced.

[0074] Please refer to Figure 5 and Figure 6 According to some embodiments of the present application, the window cover plate 260 can be connected with the shell 210 through a clamping structure; and / or, the window cover plate 260 can be connected with the shell 210 through a screwing structure.

[0075] The window cover plate 260 can be fixed through two connection modes: clamping structure and screwing structure. The two connection modes can be used alone or in combination to meet different needs.

[0076] In an example, the window cover plate 260 is connected to the shell 210 through a clamping structure. The clamping structure includes buckles 262 arranged on the edges of the window cover plate 260 and clamping grooves arranged on the edges of the operation window 2122 of the shell 210. During installation, the window cover plate 260 is aligned with the operation window 2122, and the buckles 262 are clamped into the clamping grooves by gently pressing, so as to achieve close connection. During disassembly, the window cover plate 260 can be easily removed by gently pushing the window cover plate 260 to make the buckles 262 disengage from the clamping grooves.

[0077] In another example, the window cover plate 260 can also be connected to the shell 210 through a screwing structure. The screwing structure includes screw holes arranged at the four corners of the window cover plate 260 and threaded holes arranged on the edges of the operation window 2122 of the shell 210. During installation, the window cover plate 260 is aligned with the operation window 2122, and a screw is screwed into the threaded hole through the screw hole, and the window cover plate 260 is fixed by tightening the screw. During disassembly, the window cover plate 260 can be removed by loosening the screw.

[0078] In yet another example, the screwing structure can be used to fix the four corners of the window cover plate 260, and the clamping structure can be used to assist in fixing the edges of the window cover plate 260. In this way, the reliability of the connection is ensured, and the disassembly and installation are facilitated.

[0079] According to the window cover plate 260 fixing structure of the embodiments of the present application, when the connection position of the evaporator 220 and the return air pipe 250 needs to be welded or overhauled, the window cover plate 260 can be quickly disassembled and installed through the above connection mode, which greatly simplifies the operation process and improves the work efficiency. No matter which connection mode is used, the sealing performance between the window cover plate 260 and the shell 210 can be ensured, and cold air leakage can be prevented.

[0080] Please refer to Figure 5 and Figure 6 According to some embodiments of the present application, one end of the window cover plate 260 is provided with a buckle 262, the buckle 262 is clamped with the edge of the operation window 2122, and the other end of the window cover plate 260 is provided with a connecting hole 263, the connecting hole 263 is fixedly connected with the shell 210 through a screw.

[0081] Exemplarily, the window cover plate 260 is provided with a buckle 262 away from one end of the door body, the buckle 262 is arranged on the side of the window cover plate 260 facing the shell 210 and extends away from the door body, so that the buckle 262 can be clamped and limited with the edge of the operation window 2122. The side of the window cover plate 260 close to the door body is provided with a connecting hole 263, by arranging the connecting hole 263 close to the door body, the worker is facilitated to operate, the connecting hole 263 is fixed on the shell 210 through a screw, and the installation stability of the window cover plate 260 is ensured. Through the cooperation of the buckle 262 and the connecting hole 263, the reliability of the connection is ensured, and the disassembly and installation are facilitated, and the installation convenience is greatly improved.

[0082] Please refer to Figure 3 and Figure 5 According to some embodiments of the present application, the outer side of the window cover plate 260 can be provided with a guide rail 261 for mounting a drawer.

[0083] The guide rail 261 is integrated on the window cover plate 260, so that the window cover plate 260 not only plays a role of sealing the operation window 2122, but also plays a role of supporting the drawer. Among them, the guide rail 261 can be firmly installed on the window cover plate 260 through a screw or other fixing device, to ensure that the guide rail 261 is flat and close to the surface of the window cover plate 260, avoid loose or inclined situation, ensure stability, and facilitate the maintenance and replacement of the guide rail 261; or the guide rail 261 can be integrally formed with the window cover plate 260 of the same material, which is simple to manufacture, high in production efficiency, and strong in structural stability. Among them, the guide rail 261 can be made of wear-resistant material to improve the stability and durability during long-term use.

[0084] Please refer to Figure 7 According to some embodiments of the present application, the outer side of the shell 210 can be provided with a groove 2121, the operation window 2122 can be arranged on the groove bottom of the groove 2121, the groove 2121 can be provided with a heat preservation piece 270, and the window cover plate 260 can be arranged outside the heat preservation piece 270.

[0085] The outer side of the shell 210 can be provided with a groove 2121, the size of the groove 2121 being greater than the opening size of the operation window 2122, the operation window 2122 being provided on the groove bottom of the groove 2121 to form a stepped structure on the peripheral side of the operation window 2122. The heat preservation piece 270 can be made of a material with good heat preservation performance, such as polyurethane foam, rock wool, etc., and is installed to ensure that the heat preservation piece 270 is tightly attached to the groove 2121 without leaving a gap, so as to ensure the best heat preservation effect. By setting the heat preservation piece 270, the leakage of cold air through the gap around the operation window 2122 is reduced, and the heat preservation performance of the entire air duct module 200 is improved. At the same time, the heat preservation piece 270 can also absorb certain vibrations and reduce noise. By setting the heat preservation piece 270 in the groove 2121, the sealing effect and the stability of the installation are improved. The window cover plate 260 is provided outside the heat preservation piece 270 and covers the outside of the groove 2121. The heat preservation piece 270 can be connected to the window cover plate 260 by bonding, so that the heat preservation piece 270 can be removed synchronously when the window cover plate 260 is removed.

[0086] Please refer to Figure 7 and Figure 8 According to some embodiments of the present application, the shell 210 can include a first side plate 211, a second side plate 212, a front plate 213 and a rear plate 214, the first side plate 211, the second side plate 212, the front plate 213 and the rear plate 214 being enclosed to form a cavity, and the operation window 2122 being arranged on one of the first side plate 211 and the second side plate 212.

[0087] The first side plate 211 and the second side plate 212 are arranged opposite to and spaced from each other, and the front plate 213 and the rear plate 214 are arranged opposite to and spaced from each other. Taking the refrigeration device 1000 as a vertical refrigerator as an example, one side of the refrigerator provided with a door body is the front side, and the bottom in the depth direction of the refrigeration cavity is the rear side. The shell 210 is arranged in the middle of the refrigeration cavity to divide the refrigeration cavity into a first chamber 120 and a second chamber 130 distributed along the left-right direction. Among them, the first side plate 211 and the second side plate 212 are distributed along the left-right direction, the left and right ends of the front plate 213 are connected with the front ends of the first side plate 211 and the second side plate 212 respectively, and the left and right ends of the rear plate 214 are connected with the rear ends of the first side plate 211 and the second side plate 212 respectively, so as to enclose a cavity for accommodating devices such as the evaporator 220 and the fan 240.

[0088] The rear plate 214 is also connected with the rear side of the inner container 110, the first side plate 211 corresponds to the first chamber 120, and the second side plate 212 corresponds to the second chamber 130. By arranging the operation window 2122 on one of the first side plate 211 and the second side plate 212, the operator can operate in the first chamber 120 or the second chamber 130, and the area of the operation window 2122 can be larger.

[0089] Please refer toFigure 8 In some embodiments, the front plate 213, the rear plate 214 and the first side plate 211 can be integrally formed, or the front plate 213, the rear plate 214 and the second side plate 212 can be integrally formed, so as to reduce the number of parts, and when assembling, the internal devices in the cavity are installed, and then the separate second side plate 212 or the first side plate 211 is covered at the opening position, and the separate second side plate 212 or the first side plate 211 is removed when the internal devices need to be replaced, so as to facilitate assembly and transportation, improve production efficiency, and the structure is more stable.

[0090] Please refer to Figures 9-12 According to some embodiments of the present application, the first side plate 211 and the second side plate 212 are spaced apart from each other, and the air duct module 200 can further include a volute 230, the volute 230 being arranged in the cavity, the volute 230 being arranged in a one-side opening manner on the first side plate 211 and being spaced apart from the second side plate 212, an air inlet 233 of the volute 230 being located on the side close to the second side plate 212, and a fan 240 being arranged in the volute 230.

[0091] The volute 230 is arranged to optimize the air flow path and improve the working efficiency of the air duct module 200. The volute 230 is arranged in a one-side opening manner on the first side plate 211, so that the first side plate 211 can serve as part of the sealing structure of the volute 230, simplifying the structure of the volute 230 and reducing production costs. The other side of the volute 230 is spaced apart from the second side plate 212 to allow gas to flow, so as to facilitate the gas to enter the air inlet 233 of the volute 230 when the air inlet 233 of the volute 230 is located on the side close to the second side plate 212.
