PURPOSE:To enable the temperature in a cold storage to be confirmed certainly and easily even at night by converting the temperature in the cold storage to electric signals and indicating the signal outside the cold storage by means of luminous diodes. CONSTITUTION:A refrigerating chamber and cold storage chamber temperature detectors 21 and 22 consisting of thermistors arranged in heat transmission relation to an inner box constituted of the refrigerating chamber and cold storage chamber are electrically connected with an indicator consisting of a luminous diode arranged outside the door of the cold storage through a transfer switch 23A/D converter 25, and a decoder 27. Thus, correct temperatures in the refrigerating chamber and the cold storage chamber which are detected by temmperature detectors 21 and 22 are luminously-displayed selectively as figures on an indicator 28, and the confirmation of the temperature in the cold storage can be made possible even at night. |
