とする冷凍庫のデフロスト制御装置。 In the defrost control device for a refrigerator, the defrost of the freezer is controlled by a first timer section 6, and the air inside the freezer is forcibly circulated by an internal fan motor 4, the operation of which is controlled by the first timer section 6. defrost heater 3
a second timer section TM 2 that operates in conjunction with the internal fan motor 4 and is connected to the first timer section 6; and a timer that operates in conjunction with the second timer section TM 2 to control the drive of the compressor 1. The defrost detection thermoswitch 5 is provided with a contact point 9 and a defrost detection thermoswitch 5 provided so as to be interlocked with the first timer section 6.
After the defrost cycle ends due to the operation, the first timer section 6 starts operating, and after a predetermined period of time
The internal fan motor 4 and the second timer section T
TM2 is activated, and the timer contact 9 is activated when the second timer section TM2 times up, thereby driving the compressor 1.
