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.

Object of the present invention can be achieved through the following technical solutions:

The manufacturing process of electric refrigerator housing body, comprises the steps:

Steps A. parts are prefabricated, make respectively condenser, evaporimeter, refrigeration inner bag, freezing inner bag, shell, backboard, base plate, middle cross beam, sill, dew removing tube and drainpipe; Described evaporimeter is to be coiled in advance refrigeration evaporator by one section of an evaporation tube, and another section of evaporation tube is the reserved section of refrigerating evaporator, and has been welded to connect capillary at the end of the reserved section of refrigerating evaporator; Condenser is installed on the inner side of shell; Outside the lower end of refrigeration inner bag, have compressor room room, freezing inner bag periphery is provided with dew removing tube;

Step B. is spiral around forming refrigerating evaporator to freezing inner bag is peripheral by the reserved section of the refrigerating evaporator of evaporation tube, and fixes with aluminum foil and adhesive tape;

Step C. will refrigerate inner bag with middle cross beam and be connected with freezing inner bag on operating desk, and refrigeration evaporator is overlayed to the back at refrigeration inner bag;

Step D. installs sill, drainpipe, forms prepackage inner bag;

Step e. shell is assembled with prepackage inner bag;

Step G. is connected with shell backboard and pastes fluid sealant and forms Refrigerator housing with bottom edge, the base plate and the part shell that are positioned at backboard end refrigerate the empty place formation compressor room of compressor room of inner bag outward at Refrigerator housing, the end of the end of drainpipe, the two ends of condenser, refrigeration evaporator, dew removing tube end, end capillaceous pass base plate and be positioned at compressor room;

The present invention has following outstanding substantive distinguishing features and significant progressive:

1. the electric refrigerator housing body of being manufactured by the present invention, refrigerating evaporator is that disjunctor is communicated with refrigeration evaporator, has effectively avoided cold-producing medium leaking hidden danger at memory box;

The present invention also have advantages of simple to operate, yield rate is high, low cost of manufacture.
