Description

Technical Field

[0001] This utility model relates to the field of refrigerator evaporators, and in particular to a modular refrigerator evaporation structure. Background Technology

[0002] The evaporator structure is a key component of the refrigerator's refrigeration system. Its main function is to absorb heat from inside the refrigerator, keeping the interior at a low temperature. The evaporator structure typically consists of several components, including an evaporator, a drip tray, heating elements, insulation, and a cooling fan.

[0003] The existing evaporator structure consists of multiple independently installed components. Therefore, during installation, each component needs to be pre-assembled into an accessory in stages, and then the assembled accessories are assembled into the refrigerator step by step. Specifically, the prefabrication station typically assembles the various components of the evaporator structure into three sets of accessories: the heating element and defrost protector are fixed to the evaporator, and special mounting plates are installed at both ends of the evaporator; heating elements and insulation cotton are attached to the bottom of the drip tray, and a metal braided heating strip is attached inside before being placed into the outer shell panel, secured with screws, and then an extension cable is connected; the fan and fan guard are installed on the fan mounting plate, and the fan extension cable is connected. After the various components of the evaporator structure are assembled into the above three independent accessories at the prefabrication station, they are handed over to the assembly line workers, who then assemble the three accessories into the refrigerator in sequence.

[0004] Therefore, during processing, after the three components are manufactured at the prefabrication station, they need to be allocated and placed separately on different shelves for easy retrieval on the assembly line. This results in wasted transfer time and occupies a significant amount of storage space. Assembly line workers also need to retrieve components from different shelves and install them sequentially on top of the refrigerator. This leads to a long and complex process for the evaporation structure, requiring skilled assembly to ensure accurate installation. This makes it difficult to increase the production line's uptime, resulting in high labor costs and low efficiency, which is detrimental to improving production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a modular refrigerator evaporation structure to solve the above problems. A modular refrigerator evaporation structure includes a housing, an evaporation component housed within the housing, and a fan assembly housed within the housing. The housing includes a mounting plate and a fan cover fixedly connected to the mounting plate. The evaporation component is fixedly mounted on the mounting plate, and the fan assembly is fixedly mounted on the mounting plate and located on one side of the evaporation component. The fan cover covers the outside of the evaporation component and the fan assembly and is fixedly connected to the mounting plate, so that the evaporation component and the fan assembly are combined into an independent module. The mounting plate includes a mounting plate body, a protective edge disposed on the edge of the mounting plate body, and a through hole disposed on the mounting plate body. The fan cover includes a fan cover body and an air outlet end face disposed on the fan cover body. When the evaporation component is installed inside the housing, the protective edge abuts against the edge of the evaporation component to restrict the position of the evaporation component.

[0006] Furthermore, the evaporation assembly includes an evaporator fixedly mounted on the mounting plate, a defrosting heating tube fixedly disposed on one side of the evaporator, a water receiving tray disposed on one side of the defrosting heating tube, a heating element attached to one side of the water receiving tray, and a heat insulation cotton disposed on one side of the heating element.

[0007] Furthermore, the fan assembly includes a fan mounting bracket fixedly mounted on the mounting plate, two fans fixedly mounted on the fan mounting bracket, and two fan screens fixedly mounted at the ventilation openings of the fan cover.

[0010] Furthermore, the two fans are respectively installed at the fan mounting holes, and each fan consists of a fan and a motor.

[0011] Furthermore, the fan cover is also provided with two ventilation openings corresponding to the fan.

[0012] Furthermore, extension cords are provided on the defrosting heating element, the heating plate, and the fan.

[0013] Furthermore, the fan cover also includes a fan cover flange disposed on the outer side of the fan cover body.

[0014] Compared with existing technologies, the modular refrigerator evaporator structure provided by this utility model includes the outer shell, the evaporator assembly, and the fan assembly. The evaporator assembly and the fan assembly are housed within the outer shell to form the entire evaporator structure, making the evaporator structure an independent assembly module. Furthermore, the evaporator structure can be assembled during pre-processing, allowing the component installation to be completed during prefabrication. This improves the production efficiency of the assembly line, reduces labor costs, and simplifies installation, thereby lowering the technical requirements for employees and resulting in more stable products. Simultaneously, it avoids the time-consuming and labor-intensive process of distributing components during decentralized assembly, which wastes storage space. Attached Figure Description

[0016] Figure 2 for Figure 1 A schematic diagram of the exploded structure of the evaporator structure of a modular refrigerator. Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 2 The diagram shown is a structural schematic of a modular refrigerator evaporation structure provided by this utility model. The modular refrigerator evaporation structure includes a shell 10, an evaporation component 20 housed within the shell 10, and a fan component 30 housed within the shell 10. It is conceivable that the modular refrigerator evaporation structure may also include other functional components, such as assembly components and installation components, which are all prior art known to those skilled in the art and will not be described in detail here.

[0019] The outer casing 10 includes a mounting plate 11 and a fan cover 12 fixedly connected to the mounting plate 11.

[0020] The mounting plate 11 includes a mounting plate body 111, a protective edge 112 disposed on the edge of the mounting plate body 111, and a plug-in through hole 113 disposed on the mounting plate body 111.

[0021] The mounting plate 111 is used to mount the evaporator assembly 20 and the fan assembly 30. Therefore, the mounting plate 11 has multiple mounting holes for fixing the evaporator assembly 20 and the fan assembly 30. The mounting plate 111 can be a square structure, and its size is adapted to the specifications of the evaporator assembly 20 and the fan assembly 30, so as to fix the evaporator assembly 20 and the fan assembly 30 on the mounting plate 111.

[0022] The protective edge 112 can be formed by bending the mounting plate body 111. When the evaporation assembly 20 is installed inside the housing 10, the protective edge 112 abuts against the edge of the evaporation assembly 20 to restrict the position of the evaporation assembly 20.

[0023] The insertion hole 113 is located on one side of the base plate body 111 and corresponds to the side of the evaporation assembly 20 where the wires are located. When the evaporation assembly 20 is installed inside the housing 10, the connecting wires of the various components of the evaporation assembly 20 can be organized together and led out through the insertion hole 113 to connect to the power supply.

[0024] The fan cover 12 includes a fan cover body 121, an air outlet end face 122 disposed on the fan cover body 121, and a fan cover flange 123 disposed along the edge of the fan cover body 121.

[0025] The main body 121 of the fan cover is installed on the outside of the evaporation component 20 and the fan component 30, and is fixedly connected to the mounting plate 11 by nuts and other connecting parts to form the outer shell 10. This allows the evaporation component 20 and the fan component 30 to be housed and assembled into an evaporation structure as a whole, thereby making the evaporation structure an independent modular structure for quick assembly during production.

[0026] The air outlet face 122 is inclinedly disposed on one side of the fan shroud body 121 and corresponds to the fan assembly 30 described below. Two vents are provided on the air outlet face 122, so that air can enter and exit the outer casing 10 through the vents when the fan assembly 30 is working, thereby promoting the internal air circulation of the evaporation structure.

[0027] The fan shroud flange 123 is formed by bending one side of the open end of the fan shroud body 121. When the evaporation assembly 20 is installed on the mounting plate 11, the fan shroud flange 123 coincides with the edge of the evaporation assembly 20 and is fixed to the mounting plate 11 by nuts.

[0028] The evaporation assembly 20 includes an evaporator 21 fixedly mounted on the mounting plate 11, a defrosting heating tube 22 fixedly disposed on one side of the evaporator 21, a water receiving tray 23 disposed on one side of the defrosting heating tube 22, a heating element 24 attached to one side of the water receiving tray 23, and a heat insulation cotton 25 disposed on one side of the heating element 24.

[0029] The evaporator 21 itself should be a prior art technology. In use, it allows the refrigerant to evaporate and absorb heat from inside the refrigerator, thereby achieving a cooling effect. The evaporator 21 is typically composed of an evaporator manifold, fins, inlet and outlet pipes, etc., and has different types and specifications. When producing the evaporation structure, different evaporators 21 can be selected according to the requirements of different refrigerator specifications, thereby producing evaporation structures of different specifications.

[0030] The defrosting heating element 22 is used to remove the frost layer generated on the surface of the evaporator 21 during cooling, thereby improving the cooling efficiency and service life of the evaporator 21. The defrosting heating element 22 is fixedly installed on the side of the evaporator 21 opposite to the mounting plate 11.

[0031] The drip tray 23 is located on one side of the defrosting heating element 22, and its two sides are respectively secured to the fan cover 12 under the flanges. The drip tray 23 is used to collect the condensate generated during the operation of the evaporator 21, preventing the condensate from dripping directly into the refrigerator interior or bottom, causing contamination or damage. A drain outlet is provided at the bottom of the drip tray 23, connected to an external pipe, to facilitate the drainage of the condensate collected in the drip tray 23.

[0032] The heating element 24 is fixedly attached to the side of the drip tray 23 opposite to the evaporator 21. It is used to heat the drip tray 23 to prevent the temperature of the drip tray 23 from being too low when the evaporator 21 is working to cool, which would cause the condensate in the drip tray to freeze and be difficult to drain, thus causing the condensate to overflow into the refrigerator or the bottom, causing pollution or damage.

[0033] The insulation cotton 25 covers the heating element 24 and is fixedly attached to the water receiving tray 23 to keep the heating element 24 warm and improve the working efficiency of the heating element 24.

[0034] The fan assembly 30 includes a fan mounting bracket 31 fixedly mounted on the mounting plate 11, two fans 32 fixedly mounted on the fan mounting bracket 31, and two fan screens 33 fixedly mounted at the ventilation openings of the fan cover 12.

[0035] The fan mounting bracket 31 is used to mount the fan 32, and includes a mounting bracket body 311 and two fan mounting holes 312 formed on the mounting bracket body 311.

[0036] The mounting bracket body 311 is fixedly mounted on the mounting plate 11 and located on one side of the evaporator 21. The structure of the mounting bracket body 311 is adapted to the structure of the fan cover 12, so that it can be easily accommodated in the outer casing 10 during assembly.

[0037] The fan mounting hole 312 is used to install the fan 32, which corresponds to the ventilation opening on the fan cover, thereby facilitating air circulation.

[0038] The two fans 32 are respectively installed at the fan mounting holes 312, and are typically composed of a fan and a motor. The fans 32 are used to accelerate the airflow inside the refrigerator, increase the heat exchange between the air and the evaporator 21, improve the heat exchange efficiency, and thus speed up the cooling process. At the same time, the fans 32 also play a role in preventing frost and maintaining humidity.

[0039] The fan guard 33 is disposed at the ventilation opening of the air outlet face 122 corresponding to the fan 32. It is used to prevent debris from falling into the housing 10 from the ventilation opening, thereby damaging the fan 32 and adversely affecting the evaporation assembly 20.

[0040] Extension wires are provided on the defrosting heating tube 22, the heating element 24, and the fan 32, so that the wires of the defrosting heating tube 22, the heating element 24, and the fan 32 can be organized together and led out to be connected to a power source.

[0041] In summary, the evaporation structure allows the evaporation component 20 and the fan component 30 to be fixedly mounted on the mounting plate 11 during pre-processing. The fan cover 12 is then fixedly mounted on the mounting plate 11, forming an independent module—the evaporation structure—from the evaporation component 20 and the fan component 30. During assembly line processing, the entire evaporation structure can be directly installed inside the refrigerator. This reduces the assembly steps of the evaporation structure and avoids the time-consuming and labor-intensive process of distributing parts during decentralized assembly, which wastes storage space. The partial installation during assembly line processing is completed during pre-fabrication, improving production efficiency, reducing labor costs, and lowering installation difficulty. This, in turn, reduces the technical requirements for employees, resulting in more stable product production.

[0042] Compared with existing technologies, the modular refrigerator evaporator structure provided by this utility model includes the outer shell 10, the evaporator assembly 20, and the fan assembly 30. The evaporator assembly 20 and the fan assembly 30 are housed within the outer shell 10 to form the entire evaporator structure, making the evaporator structure an independent assembly module. Furthermore, the evaporator structure can be assembled during pre-processing, allowing the component installation to be completed during prefabrication. This improves the production efficiency of the assembly line, reduces labor costs, and lowers the difficulty of installation, thereby reducing the technical requirements for employees and resulting in more stable products. Simultaneously, it avoids the time-consuming and labor-intensive distribution of components during decentralized assembly, and the waste of storage space.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
