冷式冷凍冷蔵庫の除霜回路。A freezer defrosting heater defrosts the freezer compartment cooler when the compressor is stopped, and a freezer defrost heater that integrates the operating time of the compressor and connects to the compressor for a long fixed time and defrosts the freezer compartment cooler for a short fixed time. A timer that operates to connect to a side that energizes the defrosting heater, and a freezer compartment defrosting detection thermostat that energizes the defrosting heater only when the freezing compartment cooler is in a frosted state, and in the operating state of the timer. A defrosting circuit for a direct-cooling type refrigerator-freezer, characterized in that it is configured to energize a freezer compartment heater only when a freezer compartment cooler is in a frosted state at regular intervals, which is the cumulative operating time of a compressor.
