Refrigerator

Abstract

The invention provides a refrigerator which comprises a plurality of semiconductor refrigeration assemblies and a heat conduction plate. Each semiconductor refrigeration assembly comprises a semiconductor refrigeration sheet and a draught fan arranged in front of the semiconductor refrigeration sheet, and the semiconductor refrigeration sheet is provided with a refrigeration side and a heating side which have an electronic control temperature change function; the front surface of the heat conduction plate is attached to the heating sides of the semiconductor refrigeration sheets of the multiple semiconductor refrigeration assemblies, and the back surface of the heat conduction plate is attached to an evaporator; each semiconductor refrigeration assembly is allocated to be in the mode that in the evaporator defrosting period, the heating side of the semiconductor refrigeration sheet provides heat to the evaporator through the heat conduction plate so as to melt frost on the evaporator; and the refrigeration sides of the semiconductor refrigeration sheets provide cold quality to object storage rooms through airflow driven by the draught fan, and therefore temperature fluctuation of the object storage rooms in the period is restrained. By means of the refrigerator, the cold quantity can be conveyed to the object storage rooms while the evaporator is heated for defrosting, the temperature fluctuation of the object storage rooms can be restrained, and the uniformity and efficiency of the refrigerator during defrosting of the evaporator can be improved.

Description

technical field [0001] The invention relates to the field of refrigerated and frozen storage, in particular to a refrigerator. Background technique [0002] After existing refrigerators (especially air-cooled refrigerators) have been in operation for a period of time, frost will form on the evaporator. When the amount of frosting reaches a certain level, it is necessary to stop the compressor of the refrigerator to defrost the evaporator. Current refrigerators mainly use electric heating wires to heat and defrost the evaporator. Due to the influence of two factors, the shutdown of the compressor and the heating of the electric heating wires, the temperature in the storage room of the refrigerator will fluctuate. And, when the compressor is activated again to cool the storage compartment of the refrigerator, the workload required becomes large. It can be seen that using the heating wire to defrost the evaporator in the prior art will not only increase the energy consumption...

AI Technical Summary

Problems solved by technology

However, the cold storage box occupies the effective storage space of the refrigerator, and the cold storage agent in the cold storage box still needs the cooling capacity provided by the compressor to cool down and store cold after the evaporator defrosts, so the total energy consumption of the refrigerator has not been reduced.
