In the conventional refrigerator control device configured as described above, when the outer peripheral temperature is low, the heat-retaining heater 18 is turned on to raise the temperature of the refrigerating compartment.
Since the return cool air that has cooled down is returned from the communication port 13a for the return cool air in front of the partition 13, the temperature of the outer peripheral portion for turning on the heat retention heater 18 differs depending on the set temperature of the chilled chamber 4. For example, if the set temperature of the chilled chamber 4 is lowered from the normal state, the refrigerating chamber 3 is further cooled, so that the heat retention heater in the normal state is used.
If the heat retention heater 18 is not turned on at a temperature higher than the outer peripheral temperature at which 18 is turned on, there is a problem that the food in the refrigerating compartment 3 may freeze. In the opposite case, there is a problem that the heat retention heater 18 is turned on even though it is not necessary to be turned on, resulting in a waste of electric power.
