Method for improving humidity in refrigerator for air cooling refrigerator and air cooling refrigerator

Abstract

The invention discloses an air cooling refrigerator capable of improving humidity in the refrigerator. The air cooling refrigerator comprises a refrigerator body, a door body, a compressor, an evaporator and a draught fan, wherein the inner side of the rear wall of the refrigerator body is provided with an air duct cover plate; the inner side of the air duct cover plate is provided with an air duct foam; the upper part of the air duct foam and the upper part of the air duct cover plate are provided with a plurality of air outlets; the lower part of the air duct foam and the lower part of the air duct cover plate are provided with a plurality of return air inlets; the air duct cover plate and the air duct foam form an air duct, and the air duct comprises an air supply duct and an air return duct; one or a plurality of chambers are limited in the refrigerator body; the door body is connected with the refrigerator body; the compressor is positioned at the bottom of the refrigerator body; the evaporator is installed in the air duct foam and the air duct cover plate; and the draught fan is installed close to the evaporator, and is in a normally open state. The invention also discloses a method for improving humidity in the refrigerator for the air cooling refrigerator. According to the invention, the humidity index of the air cooling refrigerator can be improved, thus the humidity in the refrigerator reaches the high moisture-retaining freshness-retaining storage requirements of fruits and vegetables, and the storage time and edible value of the fruits and vegetables are improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of refrigeration equipment, in particular to a method for increasing the humidity inside an air-cooled refrigerator, and an air-cooled refrigerator with the function of increasing the humidity inside the box. Background technique [0002] Along with the raising of people's living standard, refrigeration equipment such as refrigerator has become the necessity of people's daily life. Among them, air-cooled refrigerators refer to refrigeration equipment that relies on forced convection to achieve refrigeration. Since the evaporator used in the air-cooled refrigerator is a finned evaporator, frost is easy to form on the fins, which will affect the cooling effect of the refrigerator. Therefore, a defrosting heater is generally installed on the surface or bottom of the evaporator to regularly melt the Frost. The operation control methods of fans, compressors and defrosting heaters are a...

AI Technical Summary

Problems solved by technology

The water evaporation of fruits and vegetables, on the one hand, emits part of the water due to respiration; on the other hand, the air humidity in the storage environment is too low, which causes the fruits and vegetables to wither and reduces the edible value
