PROBLEM TO BE SOLVED: To install a device for simply and efficiently notifying the forget to close a door or a drawer to the inside or outside of a refrigerator with an alarm device (for example, sounds such as buzzer and music, or lamp), while in a conventional refrigerator, not only much electricity is wasted but also cool air is discharged, things in the refrigerator is melted or smelt, when a way of storing things is bad, so that the door is half closed or not surely closed. SOLUTION: A switch (1) is installed to each door or each drawer, to pick up information on forgetting to close a door. An alarm part 2c is activated using a gate circuit 2a and a timer device 2b.
