Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and more specifically, to a refrigerator and an assembling method thereof. Background Art

[0002] At present, refrigerator manufacturing technology is very mature, but due to the wide variety of refrigerators and various styles, there is no unified specification and standard in the industry for refrigerators designed by various refrigerator manufacturers, resulting in no unified design plan for refrigerators, making it difficult to form modular development. In particular, in recent years, air-cooled refrigerators have become the mainstream of the market and have a dominant position in the market. Air ducts, evaporators, defrost, drainage, return air pipe components, cabinet foaming, etc. are all installed separately, which results in complicated processes and low installation efficiency during the refrigerator manufacturing process, accompanied by fatal quality problems such as plugging leaks, and modular procurement cannot be achieved for refrigerator manufacturers, and standards cannot be unified.

[0003] For example, the evaporation component of the current air-cooled refrigerator mainly includes the air duct component, evaporator, cabinet, and return air pipe. During installation, the evaporator is first fixed to the cabinet, and then the return air pipe is installed and welded to the evaporator. After welding, the cabinet is foamed, and the return air pipe is foamed into the cabinet, and finally the air duct component is installed. During this period, accessories such as defrosting heating wires, water trays, sensors, etc. must also be installed on the evaporator. This installation process has many steps and is very complicated, which seriously affects the installation efficiency. Since the return air pipe needs to be foamed into the cabinet, it is impossible to process the return air pipe and evaporator into components during the processing of the evaporator. This problem has become a bottleneck problem that hinders the installation of the entire evaporation part as a component at one time; and if the return air pipe or evaporator fails during processing or use, the device cannot be replaced and repaired, which reduces the service life of the refrigerator and increases the cost of using the refrigerator. Summary of the invention

[0004] An object of the present invention is to provide a refrigerator with a quick installation of an evaporation air supply module, the evaporation air supply module of the refrigerator has a high degree of integration, and solves the problem of difficulty in installation and maintenance of refrigerator evaporation components in the prior art.

[0005] Another object of the present invention is to provide an assembling method of the refrigerator as described above.

[0006] In order to achieve the above first object, the present invention adopts the following technical scheme:

[0009] An evaporation air supply module fixed to the foaming box;

[0010] Wherein, the evaporative air supply module includes an air supply circulation component and an evaporative drainage component fixedly combined therewith;

[0011] The evaporative drainage component includes a return air pipe penetrating through the return air pipe through hole.

[0012] According to the second object, the present invention further provides a method for assembling the refrigerator as described above, comprising the following steps:

[0014] Assembling the air supply circulation component and the evaporation drainage component to form an evaporation air supply module;

[0015] Insert the return air pipe of the evaporative air supply module into the return air pipe hole on the foaming box;

[0016] Combine and fix the evaporative air supply module with the foaming box.

[0017] Preferably, the assembling method further comprises:

[0018] After the return air pipe passes through the return air pipe hole on the foam box, the inlet and outlet of the return air pipe hole are sealed with a heat insulation plug.

[0019] Preferably, the air supply circulation assembly includes an air duct assembly and a fan fixedly connected to the air duct assembly.

[0020] Preferably, the air duct assembly includes an air duct cover plate and an air duct base plate combined and fixed with the air duct cover plate.

[0021] Preferably, the evaporation and drainage assembly includes an evaporation and defrost assembly, and a drainage assembly fixedly combined with the evaporation and defrost assembly.

[0023] Preferably, the evaporator assembly includes an evaporator and an air return pipe connected to a pipe of the evaporator.

[0025] The beneficial effects of the present invention are as follows:

[0026] The refrigerator and the assembly method of the refrigerator provided by the invention realize the formation of an evaporator and all the components related to the evaporator, such as the return air pipe, air duct, fan, defrost drainage parts, sensor, etc., into an evaporation air supply module. The evaporation air supply module is directly fixed and assembled after the box is foamed, realizing the modular manufacturing of refrigerator components, greatly simplifying the installation process of the refrigerator evaporation component, simplifying the installation steps, and improving the installation efficiency.

The invention solves the industry problem of installing the refrigerator evaporation component and creates huge benefits. In addition, since the return air pipe through hole is reserved in the foaming box of the refrigerator, if the return air pipe fails during use, the device can be directly replaced, reducing the maintenance cost and use cost of the refrigerator.

[0041] The refrigerator provided by the present invention combines the air supply circulation component 11, the evaporative drainage component 12 and other components related to the evaporator into an evaporative air supply module 1.

[0042] The present invention also provides a method for assembling the refrigerator as described above, comprising the following steps:

[0043] The refrigerator body is foamed, and a return air pipe hole 21 is reserved in the foam layer of the body;

[0044] Assemble the air supply circulation component 11 and the evaporation drainage component 12 to form the evaporation air supply module 1;

[0045] Insert the return air pipe 12111 of the evaporation air supply module 1 into the return air pipe through hole 21 on the foaming box 2;
