Air pressure adjusting micro-frosting device of vertical freezer

Abstract

The invention discloses an air pressure adjusting micro-frosting device of a vertical freezer, and relates to the technical field of refrigerators. The air pressure adjusting micro-frosting device disclosed by the invention comprises a box body and a door body; an inner container is arranged in the box body; an air inlet is formed in the back wall of the inner container; an air pressure adjustingmodule is connected between the back wall of the inner container and the box body; the inner top wall of the inner container is connected with a frost blocking barrier strip; the air pressure adjusting module comprises a one-way floating ball valve; the upper end of the one-way floating ball valve is connected with a ventilating pipe communicating with the air inlet; the lower end of the one-way floating ball valve is sequentially connected with a frost blocking pipe and an air feeding pipe; the frost blocking pipe is filled with a frost blocking material; the frost blocking barrier strip comprises a fixed plate; the lower surface of the fixed plate is connected with a side baffle; the side surface of the side baffle is connected with an inclined baffle; the door body is connected with a sealing strip; and the sealing strip is connected with a strip-shaped air bag. According to the air pressure adjusting micro-frosting device disclosed by the invention, by arranging the frost blockingbarrier strip, air entering the freezer through the door body is prevented from making direct contact with an evaporator, and the moisture of the air is filtered through the air pressure adjusting module, as a result the problem that an existing vertical freezer is poor in frost blocking effect and cannot achieve a micro-frosting effect is solved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to an air pressure regulating micro-frost device for a vertical freezer. Background technique [0002] As we all know, direct cooling refrigerators or freezers, especially evaporator-wrapped freezers (commonly known as micro-frost freezers), have a disadvantage. For example, after a period of use, a large amount of frost tends to accumulate on the top of the liner and near the door seal. Seriously affect the cooling performance of the top of the vertical freezer, resulting in the phenomenon that the temperature of the top rises and the temperature difference between the compartments is large. The performance and aesthetics of this type of product are affected, and the serious frosting on the top brings great inconvenience to consumers. Frequent manual defrosting is required, and the user experience is poor. [0003] Existing frost reduction and frost resistance devices are mo...

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of air pressure adjustment micro-frost device for a vertical freezer, by setting the frost blocking bar, avoiding the air entering the box through the door from directly contacting the evaporator, and realizing the moisture content of the air through the air pressure adjustment module Filtration, which solves the problem that the existing vertical freezer has poor anti-frost effect and cannot achieve micro-frost effect
