As shown in FIG. 1, the conventional kimchi storage unit has a main body 1 for storing kimchi and a door 5 for opening and closing an upper side of the storage chamber 3 formed inside the main body 1 with a hinge portion 7. It is connected with the main body 1 by.

The inside of the storage compartment (3) is provided with a kimchi storage box (9) having a certain volume to store the kimchi on the inside, the front part of the main body (1) is provided with an operation unit 11 to control the operation of the kimchi storage do.

An upper panel 13 is installed above the main body 1 to form a part on which the door 5 is seated.

As shown in FIG. 2, the upper panel 13 includes a frame 15 having a rectangular frame shape, and a sensor 20 that detects whether the door 5 is opened in front of the frame 15. Sensor mounting portion 17 for mounting is formed.

As shown in FIG. 3, the sensor mounting unit 17 includes a front hook 18 protruding from the frame 15, and a locking jaw 19 protruding from the upper side of the front hook 18. A sensor 20 is installed between the front hook 18 and the locking jaw 19.

A magnet is installed in front of the door 5, the sensor 20 measures the distance to the door 5, and if the distance is greater than or equal to the set distance, the sensor 5 is measured with the door 5 open. The measurement is performed with the door 5 closed.

As shown in FIG. 4, the sensor 20 installed in the sensor mounting unit 17 is connected to the display circuit board 24 provided in the operation unit 11 by a wire 22.
