Title: Defrosting control system of cold accumulation type cold insulation device with refrigerator
Inventor: MASATOKI YOSHIBUMI
IPC: F25D21/06
Filed: 1989-03-22
Abstract: PURPOSE:To shorten freezing operation time by defrosting a chiller and a cooling accumulation agent if the chiller and the cooling accumulation agent is lower than predetermined temperature upon making a power supply, actuating self-sustaining means if they exceed said predetermined temperature to freeze the cooling accumulation agent, and sustaining a device itself so as for said self-sustaining means not to be actuated once said self-sustaining means is actuated. CONSTITUTION:Once a power supply switch 19 is turned on when a chiller and a cooling accumulation agent have any frost at a temperature lower than a predetermined temperature T2, bimetals 23, 29 are switched on but with a relay 17 kept off, and a heater 8 and a defrosting/cooling fan 9 are switched on. As the chiller and the cooling accumulation agent are defrosted and the bimetals 23, 29 exceed the temperature T2 and are turned off, power supply to the heater 8 is turned off with the relay 17 turned on to start the actuation of a freezing device 26. Once the chiller and the cooling accumulation agent get low temperature, the bimetals 23, 29 are turned on, the relay 17 stays at a self-sustaining state where it keeps its on-state so as not to permit the power supply to the heater 8 to be effected. Accordingly, the freezing operation is continued. When the power switch 19 is turned on in the case where the chiller and the cooling accumulation agent are higher than the predetermined temperature T2, the operation enters the freezing operation keeping the self-sustaining state.
