Abstract

PURPOSE:To permit the employment of a small-sized inexpensive changeover relay for defrosting by a method wherein the starting of a compressor after finishing defrosting is effected by a short-circuiting relay connected in parallel to the operating and defrosting circuit of a refrigerator and operating the compressor continuously for a given period of time. CONSTITUTION:A changeover relay 4 for defrosting, which stops a compressor and switches an electric circuit into a defrosting heater conducting circuit when the accumulating time of operation of the compressor has become a given value, is connected in series to a thermostat 2 controlling the continuous operation of the compressor in accordance with a temperature in a refrigerator. A short-circuiting relay 3, operating the compressor continuously for a given time upon quick refrigerating operation, is connected in parallel to the thermostat 2 and the changeover relay 4 for defrosting while short-circuiting the short- circuiting relay 3 after finishing defrosting and conducts a big current upon starting the compressor through the short-circuiting relay 3. According to this method, the small-sized and inexpensive changeover relay for defrosting may be employed.

Since the first stream of wheat in the compressor 6 decreases, the defrosting switching relay 4 is then switched to the compressor operating circuit side 44. A large current does not flow through this defrosting cutoff relay 4. After that, if the short circuit relay 3 is opened, the current of the compressor 6 flows through the thermostat 2 and the defrosting switching relay 4. According to this embodiment, since the defrosting switching relay 4 can control the large starting current of the compressor 6 without switching on and off, the contact metal of the defrosting switching relay 4 can be made small, making the defrosting switching relay 4 compact and inexpensive. 41 can be adopted.
