Refrigerator

Abstract

The invention discloses a refrigerator. The refrigerator comprises a refrigerator body, a refrigeration evaporator, a first freezing evaporator, a second freezing evaporator and a magnetic valve, wherein the refrigerator body comprises a casing, a refrigeration box inner container and a freezing box inner container, and the refrigeration box inner container and the freezing box inner container are arranged in the casing. The refrigeration evaporator is arranged on a lateral wall of the refrigeration box inner container. The first freezing evaporator is arranged on a lateral wall of the freezing box inner container and communicated with the refrigeration evaporator. The second freezing evaporator is arranged on the lateral wall of the freezing box inner container. The magnetic valve is connected with the refrigeration evaporator and the second freezing evaporator to control a refrigerant to enter the refrigeration evaporator and the second freezing evaporator. When the refrigerator refrigerates, the first freezing evaporator and the second freezing evaporator work alternatively, temperature difference in a freezing chamber is small, frosting is not easily produced in the freezing chamber, and frost layers in the freezing chamber are distributed on four lateral walls of the freezing box inner container in frosting, so that frost are convenient to remove, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] At present, the refrigeration refrigerators on the market mostly use built-in wire tube evaporators in the freezer. During the working process of the refrigerator, the surface of the evaporating coil directly exchanges heat with the air in the freezer room, which can quickly reduce the temperature in the freezer room. The temperature difference is large, and it is easy to frost on the surface of the inner tank and the surface of the evaporating coil, and it is not easy to defrost. [0003] At present, there are also some "no wind and low frost" refrigerators in the freezer that use a double evaporator circulation system, that is, the freezer uses a split evaporator, and the built-in evaporator uses a wire tube evaporator. The built-in evaporator not only occupies a certain space volume, but also is prone to frost in the compart...
