Square frame of refrigerator

Abstract

The invention belongs to the technical field of refrigeration and particularly relates to a square frame of a refrigerator. The square frame of the refrigerator comprises an inner plate and an outer plate, the inner plate comprises a first plate body, a second plate body and a third plate body, the section of a single side of each of the first to third plate bodies in a hollow square shape is in an L shape, the second plate body is positioned on the outer side of the first plate body, a long end of the first plate body is connected with a short end of the second plate body, and an insert groove is formed between the first plate body and the second plate body. The outer plate with an L-shaped section of a single side is in a hollow square shape and covers the outer side of the first plate body, a long end of the outer plate is inserted in the insert groove, a short end of the outer plate is connected with a short end of the first plate body through a clamping connection structure, and a long end of the third plate body is connected with a long end of the second plate body. The square frame of the refrigerator has the advantages that firstly, the square frame is reasonable in design, stable in structure and durable; secondly, spillage of expanded plastic from joints of the square frame of the refrigerator can be effectively prevented, and excellent refrigeration effects are achieved. By the square frame of the refrigerator, the technical problems of unreasonable design and the like in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a mouth frame of a refrigerator. Background technique [0002] The mouth frame of the freezer is used at the connection between the cabinet body and the door body of the freezer to ensure the refrigeration effect of the freezer. The current mouth frame generally adopts the splicing structure of injection molding corners and extruded profiles, which has low structural strength. There is a splicing seam between the extruded profile cutout and the splicing end face of the injection molding corner, and the splicing seam is prone to foam leakage during foaming, which affects the quality of the product. In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. [0003] For example, the Chinese patent document discloses a freezer mouth frame [Application No.: 201420230062.7], which includes a frame body...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme has improved some problems of the prior art to a certain extent, but the scheme also has at least the following defects: the design is unreasonable, the splicing seam is prone to leaking bubbles when foaming, and the refrigeration effect of the refrigerator is poor. question
