Refrigerator body manufacturing process

Abstract

The invention relates to the technical field of refrigerators and provides a refrigerator body manufacturing process. The refrigerator body manufacturing process comprises the steps of prefabricating components and parts, splicing and sealing the components and parts to form a refrigerator casing, filling a foaming material into the refrigerator casing and performing a foaming work procedure to manufacture a refrigerator body. The components and parts include a condenser, an evaporating pipe, a refrigeration inner container, a freezing inner container, an outer casing, a back plate, a base plate, a middle cross beam, a lower cross beam, a dew removing pipe and a drainage pipe. The refrigerator body manufacturing process is characterized in that a freezing evaporator and a refrigeration evaporator form a non-welded one-piece communicating pipe, and accordingly leakage of a refrigerant in the refrigerator body can be effectively avoided, and has the advantages of being simple in operation, high in finished product rate and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a manufacturing process of a cabinet of a refrigerator. Background technique [0002] In the prior art, the manufacturing process of the refrigerator box includes the following steps. [0003] step a. Parts prefabrication, making condensers, refrigerated evaporator tubes, refrigerated evaporator tubes, refrigerated inner tanks, refrigerated inner tanks, shells, back panels, bottom plates, middle beams, lower beams, dew pipes and drain pipes; pre-wound refrigerated evaporation tubes It is an S-shaped refrigerated evaporator, with a condenser installed in the outer shell, and a dew removal pipe installed around the refrigerated liner; [0004] Step B. Wrap the refrigerated evaporator tube spirally around the periphery of the refrigerated liner to form a refrigerated evaporator, and fix it tightly with adhesive tape; and weld a capillary tube at one end of the refrigerated ...

AI Technical Summary

Problems solved by technology

[0012] In the existing manufacturing process of this refrigerator box, the refrigerated evaporator and the refrigerated evaporator are manufactured separately in steps A and B and then communicated by welding, which has the following disadvantages: 1. The welding process is difficult to operate and the cost is high. 2. The welding point of the two is deeply buried in the refrigerator box. Once the refrigerant leaks at this point during use, it cannot be repaired.
