Refrigerator

Abstract

The invention discloses a refrigerator, which comprises a refrigerator body, a freezing chamber door body, a refrigerating chamber door body, a freezing evaporator and a heat exchange part, wherein the heat exchange part is arranged in a refrigerating chamber and communicated with a freezing chamber through an air inlet and an air return port; and the heat of the air of the freezing chamber is exchanged with the heat of the air of the refrigerating chamber by using the heat exchange part. According to the refrigerator provided by the embodiment of the invention, cold exchange of the refrigerating chamber and the freezing chamber is realized by using the heat exchange part, direct contact of the air of the freezing chamber and the air of the refrigerating chamber is avoided, and the humidity of the refrigerating chamber can be more than 70 percent, so the freshness-preserving performance of the refrigerating chamber is improved. Moreover, direct impact of the low-temperature cold air of the freezing chamber on the refrigerating chamber is avoided, so the phenomenon of temperature fluctuation in the refrigerating chamber is greatly improved, and the freshness-preserving performance of the refrigerating chamber is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of household appliances, and more specifically, the invention relates to a refrigerator. Background technique [0002] At present, most of the existing side-by-side door products are single-system air-cooled machines, which are characterized in that: the freezer is equipped with a set of refrigeration system, mainly including fin evaporator and convection fan, and the fin evaporator provides cooling capacity for the freezer , while the convection fan rotates to force the air in the freezing chamber to pass through the finned evaporator to improve the heat exchange effect. The refrigerating room uses an air duct to directly blow the low-temperature air (usually -18 degrees Celsius) in the freezing room into the refrigerating room, mixes with the air in the refrigerating room, and then flows back into the freezing room through the air return port, thereby reducing the temperature in the refriger...

AI Technical Summary

Problems solved by technology

This type of single-system air cooler has a simple structure, but because the -18°C dry air in the freezer is mixed with the air in the refrigerator, the relative humidity in the refrigerator is often around 20%, which is very unfavorable for the freshness of the refrigerator.
