Refrigerator

Abstract

The invention provides a refrigerator. A refrigerating evaporator, a chilling evaporator and a variable temperature evaporator are respectively arranged in a refrigerating chamber, a chilling chamber and a variable temperature chamber of the refrigerator; the first end of the refrigerating evaporator and the first end of the chilling evaporator are connected with the first end of a condenser; first solenoid valves are arranged among the refrigerating evaporator, the chilling evaporator and the condenser; the first solenoid valves are used for switching on or off the refrigerating evaporator and / or the chilling evaporator; the second end of the refrigerating evaporator and the second end of the chilling evaporator are connected with the first end of the variable temperature evaporator; and the second end of the variable temperature evaporator is connected with an inlet of a compressor. According to the refrigerator provided by the invention, the refrigerating evaporator and the chilling evaporator run separately to realize dual-temperature control, the maximum load of the compressor is reduced, and the food is prevented from being tainted by other odor; and meanwhile, the redundant cooling capacity produced by the refrigerating evaporator and the chilling evaporator is used in the variable temperature chamber to be completely used, and the energy efficiency of a cooling system is improved.

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...
