[0002] Now the cooling effect of the refrigerator is gradually improving, and the energy consumption is also gradually increasing. The improvement of the cooling effect has also led to an increase in the time and frequency of icing on the surface of the evaporator. The existing heating and defrosting method is extensive, only in the evaporation Add a heating tube to the bottom of the device, and the top is far away from the bottom heating tube, which will make the frost in this area melt slowly, and even the frost in this area will not completely melt after the defrosting is over. Therefore, it is necessary to Some evaporator defrosting devices are improved

The invention relates to an evaporator defrosting device. The evaporator defrosting device comprises a motor, a first rack, a second rack, a first fin group and a second fin group, wherein the first rack and the second rack relatively move in the transverse direction under driving of the motor, and the first fin group and the second fin group are in corresponding linkage with the first rack and the second rack separately. The first fin group and the second fin group are both provided with a plurality of fins which are arranged at intervals, and two adjacent fins of each fin group in the firstand second fin groups are separated by a certain distance to form fin gaps. The fins in the first fin group and the fins in the second fin group are arranged in a staggered mode, the fins of at leastone fin group of the first fin group and the second fin group are provided with defrosting units, and the defrosting units move along with the fin group fixed to the defrosting units and remove froston the fins in the other fin group, so that the defrosting efficiency is improved, and defrosting time is reduced.
Description
technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator with an evaporator defrosting device. Background technique [0002] Now the cooling effect of the refrigerator is gradually improving, and the energy consumption is also gradually increasing. The improvement of the cooling effect has also led to an increase in the time and frequency of icing on the surface of the evaporator. The existing heating and defrosting method is extensive, only in the evaporation Add a heating tube to the bottom of the device, and the top is far away from the bottom heating tube, which will make the frost in this area melt slowly, and even the frost in this area will not completely melt after the defrosting is over. Therefore, it is necessary to Some evaporator defrosting devices are improved. Contents of the invention [0003] The object of the present invention is to provide an evaporator defrosting device with high defrosting ef...
