Problems solved by technology

During the working process of the refrigerator, the surface of the evaporating coil directly exchanges heat with the air in the freezer room. Although it can quickly reduce the temperature in the freezer room, due to the large temperature difference between the rooms, it is very easy to evaporate on the surface of the inner tank of the freezer room. The surface of the coil is frosted, and the frosted parts are unevenly distributed, so it is not easy to defrost
[0005] At the same time, as far as the applicant knows, the existing freezer refrigeration ge

Embodiment

[0019] The double refrigeration system that is used for refrigerator of present embodiment, as figure 1 As shown, it includes a compressor, a condenser connected to the outlet of the compressor, a first refrigerating evaporator, a refrigerating evaporator for cooling the refrigerating room, and an electric switching valve. The compressor is located in the compressor chamber at the rear lower part of the refrigerator box. The refrigerating evaporator is generally arranged on the outer side wall of the tank of the refrigerating room. Of course, the refrigerating evaporator can also be arranged on the inner side wall of the refrigerator compartment.

[0020] The outlet of the condenser is connected to the inlet of the electric switching valve, the outlet of the electric switching valve is respectively connected to the inlet of the refrigeration evaporator and the first refrigeration evaporator through the refrigeration capillary 1 and the refrigeration capillary 2, and the outle...

Abstract

The invention relates to a double refrigerating system for a refrigerator, and belongs to the technical field of refrigerators. The refrigerating system comprises a compressor, a condenser, a first freezing evaporator, a cold-storage evaporator and an electric switching valve. The outlet of the condenser is connected with the inlet of the electric switching valve, the outlet of the electric switching valve is connected with the inlets of the cold-storage evaporator and the first freezing evaporator respectively through cold storage capillary tubes and freezing capillary tubes, the outlet of the cold storage evaporator is connected with the inlet of the first freezing evaporator, a second freezing evaporator is arranged inside a freezing room, and a second freezing evaporator is connected between the inlets of the first freezing evaporator and the compressor in series. The first freezing evaporator is a winding tube arranged between an existing refrigerator thermal insulating layer and a freezing room box liner and is evenly wound on the peripheral side wall on the outer side of the freezing room box liner, and the second freezing evaporator is arranged on the inner side of the freezing room box liner and on the upper portion of the side face opposite to the door of the refrigerator. The frosting of the freezing room of the refrigerating system is evenly distributed and frost is easy to remove.
