。[Scope of Claim for Utility Model Registration] (1) A temperature-sensitive reed switch installed inside the refrigerator body, and a temperature-sensitive reed switch installed on the door that is oriented and positioned so as to cancel the magnetic force of the temperature-sensitive reed switch when the door is closed. The temperature-sensitive reed switch is equipped with a reed switch in which temperature-sensitive ferrite is formed into a sandwich structure using magnets, and the temperature-sensitive ferrite is arranged at appropriate intervals. The reed switch opens and closes when the magnetic lines of force passing through the reed switch change, and when the temperature near the temperature-sensitive reed switch is high when the door is ajar, and the magnetic lines of force of the magnet on the door act, the reed switch opens and closes. An ajar door detection device for a refrigerator, which detects when the door is closed and is not completely blocked, and issues an alarm. (2) A practical device characterized in that it detects that the refrigerator outlet is connected to a power source and does not issue an alarm even if the temperature inside the refrigerator is high or the reed switch is closed due to the magnet on the door. A refrigerator door ajar detection device according to claim 1 of the patent registration claim.
