refrigerator

Abstract

The invention provides a refrigerator, the refrigerating chamber, the freezing chamber and the temperature-changing chamber of the refrigerator are respectively provided with a refrigerating evaporator, a freezing evaporator and a variable-temperature evaporator, and the first port of the refrigerating evaporator and the first port of the freezing evaporator are connected with each other. The first port of the condenser is connected, and a first electromagnetic valve is arranged between the refrigerating evaporator, the refrigerating evaporator and the condenser, and the first electromagnetic valve can control the on-off of the refrigerating evaporator and / or the refrigerating evaporator; Both the second port of the refrigerator and the second port of the freezing evaporator are connected with the first port of the variable temperature evaporator, and the second port of the variable temperature evaporator is connected with the inlet of the compressor. The refrigerator provided by the invention can realize the independent operation of the refrigerating evaporator and the freezing evaporator, achieve dual temperature and dual control, reduce the maximum load of the compressor, and prevent food odors; The amount can be used in the temperature-changing greenhouse to make full use of the cooling capacity and improve the energy efficiency of the refrigeration system.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a refrigerator. Background technique [0002] Existing refrigerators usually have three compartments or more than three compartments. Mechanical refrigerators usually use three compartment evaporators in series to achieve cooling in different compartments of the refrigerator. However, when one of the compartments does not need cooling capacity , the refrigeration system of the refrigerator is still turned on, resulting in unnecessary energy consumption; new computer refrigerators usually use the form of parallel connection of the evaporators in the three compartments to achieve cooling in different compartments of the refrigerator, but this will cause frequent start and stop of the refrigerator refrigeration system, Lead to high energy consumption; air-cooled refrigerators are usually limited to a single evaporator for cooling, or use two evaporators in series to achi...
