refrigerator

Abstract

The invention provides a refrigerator, which includes a refrigerating room, a temperature-changing room, a freezing room and a refrigeration system. An evaporator cavity is arranged at the rear of the freezing room, and the refrigerating room and the changing room are respectively connected to the The lower part of the evaporator cavity is connected; the refrigeration system includes a compressor, a condenser, a capillary tube, an evaporator and a return air pipe connected in sequence in a loop, and at least part of the return air pipe is arranged in the return air duct. Compared with the prior art, the beneficial effect of the present invention is: when the condensation effect of the evaporator is insufficient, the secondary condensation is increased, so that the humidity in the air flowing through the evaporator is reduced, and the moisture is reduced, thereby reducing the formation of frost on the damper , when there is no more water on the damper, the problem of freezing of the damper will not occur.

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.
