Problems solved by technology

There are still disadvantages such as uneven defrosting or prolonged defrosting time caused by uneven heat distribution
[0005] In addition, the cold end of the semiconductor refrigeration chip is connected to the refrigerator freezer. Due to the low cooling efficiency of the semiconductor and the poor cooling effect under low temperature conditions, the overall efficiency is low.

Abstract

The invention relates to a refrigeration appliance. The refrigeration appliance comprises a refrigeration system which comprises a compressor, a condenser, an evaporator and a first pipeline connected with the compressor, the condenser and the evaporator; and a defrosting system comprises the evaporator, a heating component and a second pipeline connected with the evaporator and the heating component, a defrosting medium is arranged in the second pipeline, and the defrosting medium circularly flows between the heating component and the evaporator through the second pipeline and is heated when flowing through the heating component. By means of the independent defrosting circulation system provided by the scheme, uniform defrosting can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of refrigeration appliances, in particular to a refrigeration appliance. Background technique [0002] Refrigerator has become one of indispensable household appliances in people's daily life. In recent years, air-cooled refrigerators have been widely used because of their advantages such as fast cooling speed and relatively uniform temperature distribution in the compartments. [0003] Existing air-cooled refrigerators usually use electric heating wires to defrost, but the local high temperature and leakage of electric heating wires pose safety hazards, and there is a problem of high energy consumption for defrosting. On the other hand, the heating wire is generally installed at the bottom of the evaporator, and the defrosting is carried out from the bottom to the top through heat radiation, which can easily cause uneven defrosting, and thus has the disadvantage of difficult precise d...
