Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a cold storage chamber, a freezing chamber and a refrigeration system. An evaporator cavity is formed behind the freezing chamber. Thecold storage chamber communicates with the upper portion of the evaporator cavity through a cold storage chamber air supply air flue. The cold storage chamber communicates with the lower portion of the evaporator cavity through an air return air flue. The refrigerator further comprises a humidity adjusting device, one end of the humidity adjusting device is arranged in the cold storage chamber air supply air flue, and the other end of the humidity adjusting device is arranged in the air return air flue. Compared with the prior art, the refrigerator has the beneficial effects that when the condensation function of the evaporator is insufficient, secondary condensation is increased, so that humidity in air flowing through the evaporator is reduced, water is reduced, forming of frost on an air door is reduced, and when no water exists in the air door, the problem of air door freezing is solved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a refrigerator. Background technique [0002] Existing single-system air-cooled three-door refrigerators include a refrigerating chamber, a temperature-changing chamber, a freezing chamber and a refrigeration system for cooling each refrigeration chamber. The refrigeration system components include: a compressor, an evaporator, a condenser, and a blower fan. The evaporator is set at the back of the freezer, where the refrigerant exchanges heat with the surrounding air and evaporates into a gaseous refrigerant, while cooling the surrounding air. The cooled air is driven by the fan to flow partly to the freezer and partly to the refrigerator. room and temperature-changing room, wherein the cold air flowing to the refrigerating room and the temperature-changing room are regulated by their respective dampers, and the dampers are usually located on the top of ...

Problems solved by technology

The evaporator is set at the back of the freezer, where the refrigerant exchanges heat with the surrounding air and evaporates into a gaseous refrigerant, while cooling the surrounding air. The cooled air is driven by the fan to flow partly to the freezer and partly to the refrigerator. room and temperature-changing room, wherein the cold air flowing to the refrigerating room and the temperature-changing room are regulated by their own dampers, which are usually located on the top of the freezing room, and the dampers are easy to freeze and then freeze. After the dampers are frozen, it will affect The air-conditioning delivery in the refrigerator room and the temperature-changing room makes the temperature in the refrigerator room or the temperature-changing room uncontrolled, or the temperature is too high, or the temperature is directly close to freezing, and the food in the refrigerator room or the temperature-changing room is frozen.
