The magnetic sensor 9 inputs a door opening / closing signal to the control unit 8 composed of a microcomputer or the like. In response to the input signal, the control unit 8 outputs a signal to the semiconductor element 7 that controls ON / OFF of the interior lamp 2, and similarly, the cooling blower 4
The signal is output to the semiconductor element 6 that controls ON and OFF. Reference numeral 1 is a commercial power source, and 3 is a thermostat for intermittently operating the cooling compressor 5 depending on the temperature in the refrigerator.

するものである。FIG. 2 is a flow chart showing that when there is no open output from at least one of the freezer compartment door and the refrigerating compartment door, the blower is operated and the interior light is turned off. Unless it continues for a time (for example, 2 hours), the blower is stopped and the internal light is turned on. When the open output from at least one side continues for a certain period of time, in order to prevent the temperature inside the refrigerator from rising, the blower is operated and the inside lamp is turned off.

Is a refrigerator compartment door and has a magnet 15 at the top. Reference numeral 13 is a cover for the central portion, which incorporates the magnetic sensors 9 and 10. When the door is open, the distance between the magnet and the magnetic sensor is long, and when the door is closed, the positions of the magnet and the magnetic sensor are close, so that the magnetic sensor output fluctuates greatly.
