備えた除霜装置。 A heating device that heats the cooler of the refrigeration cycle to defrost it, and a temperature sensor that detects that the temperature of the cooler has risen to a predetermined temperature during the defrosting and operates to de-energize the heating device. and a cam connected in parallel with the temperature sensor and having a defrost limit time set so as to turn off the heating device after the time required to completely finish defrosting from the start of defrosting. The mechanical defrost timer and the end signal from the temperature sensor will not start defrosting again within the defrost time limit of the defrost timer, and will not restart even if there is an electrical failure such as a temporary power outage. A defrosting device equipped with a control relay that forms a holding circuit so that the front and rear circuits do not change.
