A micro-frost device for air pressure adjustment of vertical freezer

Abstract

The invention discloses an air pressure regulating micro-frost device for a vertical freezer, which relates to the technical field of refrigerators. The invention comprises a box body and a door body; an inner tank is arranged in the box body; an air inlet is provided on the back wall of the inner tank; an air pressure regulating module is connected between the back wall of the inner tank and the box body; Frost barrier; the air pressure adjustment module includes a one-way float valve; the upper end of the one-way float valve is connected with a ventilation pipe connected with the air inlet; Frost material; the frost blocking bar includes a fixed plate; the lower surface of the fixed plate is connected with a side baffle; the side of the side baffle is connected with an oblique baffle; the door body is connected with a seal; The present invention avoids the direct contact of the air entering through the door with the evaporator by setting the frost blocking bar, and realizes the moisture filtration of the air through the air pressure adjustment module, which solves the problem that the existing vertical freezer has poor frost blocking effect and cannot achieve micro Frost effect problem.

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. It affects the performance and aesthetics of this type of product. 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 mostly used ...
