<p>There is provided a storage room in which an infrared sensor detecting a surface temperature of a food is installed, and an adjacent storage room which is adjacent on a projection surface of a detection surface of the infrared sensor starting from the infrared sensor, an improvement of precision of a detection temperature at a time of opening and closing a door can be achieved by setting the storage room and the adjacent storage room to the same temperature zone, and a temperature of the food can be stably detected by suppressing a dew condensation and a temperature fluctuation of a thermistor itself which are factors of an erroneous detection.</p> |
