Refrigerator

Abstract

The invention provides a refrigerator, which comprises a refrigerating system, a first switching unit, a second switching unit, a heat insulation component and a controller. The refrigerating system comprises a compressor, a main condenser, capillary tubes and evaporators, wherein the compressor, the main condenser, the capillary tubes and the evaporators are connected in sequence, and the evaporators include a refrigerating evaporator, a heat insulating chamber evaporator and a freezing evaporator which are connected in series. Each of the first switching unit and the second switching unit is provided with an inlet, a first outlet and a second outlet, the inlet of the first switching unit is connected with an outlet of the compressor, the first outlet of the first switching unit is connected with an inlet of the main condenser, the inlet of the second switching unit is connected with an outlet of the refrigerating evaporator, the first outlet of the second switching unit is connected with an inlet of the heat insulating chamber evaporator, and the second outlet of the second switching unit is connected with an inlet of the freezing evaporator. The heat insulation component is arranged between the second outlet of the first switching unit and the inlet of the main condenser. The controller is used for controlling to switch the first outlet of the first switching unit and the first outlet of the second switching unit into the second outlets thereof when a heat insulating chamber of the refrigerator is heated. The refrigerator in the embodiment is low in energy consumption, and the heat-insulation temperature of the heat insulating chamber of the refrigerator can be maintained within a short time.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] With the continuous development of refrigerators, some three-door refrigerators have appeared in recent years. In addition to the cold room and freezer room of traditional double-door refrigerators, they also have a variable room. The controllable temperature of the variable room is generally in the cold room and freezer room In this way, it can meet the storage requirements of more food and so on. [0003] Even the above-mentioned three-door refrigerator cannot meet the requirements of more users for food preservation. Later, some refrigerators have a heat preservation room, and the temperature adjustment range of the heat preservation room is very large. It can be used for cooling or heating. When the heat preservation room needs to be heated and kept warm, the heat preservation room can be adjusted to work in the h...

AI Technical Summary

Problems solved by technology

[0004] 1. The heat preservation chamber of the refrigerator is heated and kept warm by means of microwave heating, but this method overlaps with the heating function of the microwave oven, which is not very practical, and at the same time increases the cost of the refrigerator

[0005] 2. Use electric heaters such as quartz tubes to electrically heat the insulation room, but in this way, no matter what kind of heat preservation needs the customer has, they need to turn on the electric heater, which increases the power consumption of the refrigerator
