る。However, in conventional refrigerator devices that remotely control the locking and unlocking of the refrigerator door, even if a door locking command is sent from an operation unit such as the front desk,
It is not always possible to check whether the locking/unlocking mechanism of the refrigerator device is operating normally from the operating section such as the front desk. For example, in the "automatic remote control refrigerator door locking device" described in the above-mentioned Japanese Utility Model Application Publication No. 56-169061, a main solenoid is attached to the outer wall of the refrigerator body, and an auxiliary solenoid is provided to maintain the suction release state of the main solenoid. A locking/unlocking mechanism is provided with a solenoid and a metal part on the door side that fits into the cylinder part of the above-mentioned main solenoid. Therefore, the main components of this electromagnetic locking/unlocking mechanism, such as the solenoid, may malfunction (
If a thermal fuse blows, etc.), even if a signal is sent from the operating section, the signal is sent to the solenoid section, but the actual locked/unlocked state cannot be confirmed from the operating section.
