Abstract

The invention discloses a frostless refrigerator capable of defrosting through coupling of ultrasonic waves and super-hydrophobic materials, and a control method of the frostless refrigerator. The frostless refrigerator comprises a master controller, an evaporation chamber, a refrigerating chamber, a cold storage chamber, a compressor, a drainage device, an environmental temperature sensor and a magnetic sensitive control air valve, wherein the master controller is separately connected with a ultrasonic wave oscillation system, the compressor, an electric heater, the magnetic sensitive control air valve, a fan, the environmental temperature sensor, a refrigerating chamber temperature sensor, an evaporator temperature sensor and a cold storage chamber temperature sensor, and the ultrasonic wave oscillation system and the electric heater are defrosting devices; the surface of an evaporator, the surface of a refrigerating chamber air channel, the surface of a refrigerating chamber air-return vent, the surface of a cold storage chamber air channel, and the surface of a cold storage chamber air-return channel are made from super-hydrophobic materials. According to the frostless refrigerator and the control method thereof disclosed by the invention, frosting surfaces are treated by using the super-hydrophobic materials, ultrasonic waves and electric heating are coupled, on-line defrosting is performed in a manner that the frostless refrigerator does not stop, the stable running environment of the refrigerator is guaranteed, and the service life of the refrigerator is prolonged.

Description

technical field

[0001] The invention relates to a frost-free refrigerator using ultrasonic waves coupled with superhydrophobic materials for defrosting and a control method thereof, in particular to materials for reducing frosting, control rules for automatic defrosting of frost-free refrigerators, and an ultrasonic system for realizing automatic defrosting. Background technique

[0002] First of all, when the heat conduction electric heater is used for defrosting in a frost-free refrigerator, because the heat conduction electric heater is embedded in the fin and wraps the evaporator in a large area, the heat is mainly transmitted to the frost layer and the evaporator through the fin, and its melting The frost hysteresis rate was 61.4%. The main body of the radiant convection electric heater is located below the evaporator, and its heat is mainly transferred to the frost layer by radiation and hot air convection. The defrosting hysteresis rate is as high as 83.6%, indicating...
