Defrosting system and defrosting method for air cooling refrigerator and air cooling refrigerator

Abstract

The invention discloses a defrosting system of an air cooling refrigerator. The system is arranged in the air cooling refrigerator and comprises a temperature sensor, a controller and a heating mechanism. The temperature sensor is connected with an evaporator and used for detecting temperature information of the evaporator. The controller is connected with the temperature sensor and the heating mechanism and controls the work state of the heating mechanism according to the temperature information. The heating mechanism comprises a first heating element and a second heating element. The first heating element is arranged on the side wall of the evaporator. The second heating element is arranged at the bottom of the evaporator. The invention further discloses a defrosting method corresponding to the defrosting system and the air cooling refrigerator. According to the defrosting system, the defrosting method and the air cooling refrigerator, due to the fact that two or more heating elements are arranged on one evaporator, combined heating and defrosting are achieved, and defrosting uniformity is guaranteed. Meanwhile, defrosting time can be effectively shortened in this way, the defrosting efficiency is improved, electric energy consumption can also be reduced, the fluctuation range of the temperature in the refrigerator is reduced during defrosting, and food storage quality is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a defrosting system, a defrosting method and a refrigerator. Background technique [0002] Air-cooled refrigerators, also known as frost-free refrigerators, are gradually favored by more and more consumers due to their advantages of fast cooling speed, uniform temperature inside the cabinet, and no need for manual defrosting / frost, and their share in the high-end refrigerator market is increasing day by day . However, there is also frost in the air-cooled refrigerator, but the frost in the refrigerator is condensed on the evaporator, which is usually removed by thermal evaporation. However, in the prior art, heating components are generally installed at the bottom of the evaporator, which often leads to uneven defrosting, and the bottom of the evaporator may be overheated, but the frost layer on the top has not completely melted. Moreover, due to the long heating time and...
