Refrigeration equipment and manufacturing method thereof

Abstract

The invention discloses refrigeration equipment. The refrigeration equipment comprises a box body and an inner container, wherein the box body comprises a top cover, a left side plate, a right side plate and a rear upper beam; the left side plate and the right side plate are vertically connected to the left side and the right side of the top cover respectively; the rear upper beam is connected tothe rear edge of the top cover, and the left and right ends of the rear upper beam are respectively connected with the left side plate and the right side plate; the inner container is arranged in thebox body; a foaming space for foaming to form an insulating layer is formed between the inner container and the box body; and the rear upper beam is manufactured by processing a plastic part. The rear upper beam of the box body is manufactured by a plastic section process, so compared with the conventional refrigeration equipment, the refrigeration equipment in the embodiment of the invention hasthe advantages that: the structural strength of the box body is unchanged but the cost is greatly reduced; and the manufacturing process is environmental-friendly. The invention also discloses a method for manufacturing the refrigeration equipment.

Description

technical field [0001] The invention relates to the field of refrigeration equipment manufacturing, in particular to a refrigeration equipment and a manufacturing method thereof. Background technique [0002] At present, in the existing technology of refrigerator manufacturing, there are two kinds of process materials for the back panel of the refrigerator, one is the more traditional galvanized sheet, and the other is the relatively new PS (Polystyrene-polystyrene) extruded sheet. It is a kind of plastic backplane. Because of its advantages in material cost, the latter has been widely used in various brand products quickly. However, due to the insufficient strength of this back panel before foaming, a sheet metal rear upper beam has to be used to increase the rigidity during the assembly process of the side panels, beams, and inner tanks before the box body is foamed, so as to prevent the foaming of the box body before foaming. , the back panel is deformed due to its own w...

AI Technical Summary

Problems solved by technology

However, due to the insufficient strength of this back panel before foaming, a sheet metal rear upper beam has to be used to increase the rigidity during the assembly process of the side panels, beams, and inner tanks before the box body is foamed, so as to prevent the foaming of the box body before foaming. , the rear panel is deformed due to its own weight, which affects the normal progress of the foaming process

[0003] The above-mentioned sheet metal rear upper beam is mostly a metal beam with an "L" shape in cross section, and the surface is sprayed for anti-rust treatment, which is costly. In addition, the thermosetting plastic powder spraying and manufacturing process also causes certain pollution to the environment
