Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator is provided with a first evaporator and a second evaporator which provide cold energy for different storage chambers. Creatively, when the refrigerator enters the mode that the second evaporator independently conducts refrigeration, a flow channel switching device enables liquid-state refrigerants in the first evaporator to be fully migrated,whether all the refrigerants are completely migrated or not is judged according to a detected temperature at an outlet of the first evaporator, and when all the refrigerants are migrated, the refrigerant directly enters the second evaporator without passing through the first evaporator. The refrigerator can achieve the effect of only refrigerating one storage chamber, so that resource waste caused when one storage chamber needs refrigeration and the other storage chamber does not need refrigeration is avoided; and besides, it can be guaranteed that when one evaporator independently conducts refrigeration, liquid-state refrigerants cannot remain in the other evaporator, it is guaranteed that sufficient refrigerants exist in the evaporator independently conducting refrigeration, the refrigeration effect is not influenced, and the utilization ratio of the refrigerants is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] Due to the different types of food stored in the refrigerator, refrigerators generally have multiple storage compartments, such as freezer compartments, refrigerator compartments, etc., but users have different requirements for different storage compartments, for example, when users only need to use one storage compartment When there are multiple storage compartments, if multiple storage compartments are refrigerated at the same time, resources will be wasted. [0003] Although there are refrigerators with double evaporators, the two evaporators can cool different storage compartments respectively, but when one evaporator in this refrigerator is refrigerated alone, part of the liquid will remain in the other evaporator. Refrigerant, resulting in insufficient refrigerant in the evaporator for separate refrigeration, af...
