The position sensor 100 is installed on one side of the top surface of the door 13 and the bottom 11a of the washing tank 11 to detect the presence of the shelf 12. In particular, the position sensor 100 is the front of the upper surface of the door 13 and the bottom 11a of the cleaning tank 11 so as to detect the presence of the shelf 12 through the wheels 12a and 12b of the shelf 12. It is preferable to be installed in the rear.

In this case, the position sensor 100 installed in front of the upper surface of the door 13 detects the front wheel 12a of the shelf 12 from which the shelf 12 is drawn out from the washing tank 11. The position sensor 100 installed at the rear of the washing tank bottom 11a detects the rear wheel 12b of the shelf 12 in which the shelf 12 is introduced into the washing tank 11.

The shelf 12 is only located inside the washing tank 11 or is only operated to be drawn out of the washing tank 11 through the upper surface of the door 13, except when removed from the washing machine 10. Is a state detected by the position sensors 100.

If the shelf 12 is removed from the washing machine 10 and the position sensor 100 does not detect the shelf 12, an absence signal is output from the position sensor 100. The absence signal is input to the notification means 200, the notification means 200 performs a notification operation only when the absence signal is input from each of the position sensors (100).

On the other hand, when the user simply enters or withdraws the shelf 12 into the washing tank 11, the absence signal is not input from each of the position sensors 100 to prevent the case in which the notification means 200 is operated. In order to do this, the operation of the notification means 200 is preferably set to be performed after a few seconds have elapsed after the absence signal is input from each of the position sensors 100.
