If the power on switch is not pressed, the indicator lamp will not light up even if you press the switch to set the next washing content, and this will make you realize that you forgot to press the power on switch, and the switch to set the washing content will not light up. The pressure is adjusted according to the quantity, quality, and dirtiness of the clothes you are about to wash, so you will never forget to press the button. However, since the start switch is pressed last, and after setting the contents, which is the main switch operation, there is a risk of forgetting to press the start switch and closing the lid, resulting in the washing operation not starting.

[0006] Particularly, as seen in, for example, Japanese Utility Model Application Publication No. 1-79483, in a washing machine in which a display board having a setting switch provided on the operation panel is covered by the lid when the lid is closed, Once the lid is closed, the input operation section is covered by the lid and cannot be seen, making it even more difficult to notice if you forget to press the start switch.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, reduce the number of switch operations to be performed at the start of operation, thereby reducing the number of steps required, and in particular omit the start switch, which is easy to forget to press, so that the washing operation can be carried out without pressing the start switch. The objective is to provide an easy-to-use method of operating a washing machine that allows you to start operating a washing machine.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention covers the clothes input port at the top of the washing/dehydration tank with a lid that can be opened and closed, and is provided with a lid opening/closing switch for detecting opening/closing of the lid. The gist is that when the machine is powered on and the lid is closed, a washing operation is automatically started in response to a lid closing detection signal from a lid opening/closing switch.

[0009]

[Operation] According to the present invention, after the power is turned on by pressing the power on switch, laundry and detergent are put into the washing and dehydrating tank, and then when the lid is closed, the lid opens and closes in conjunction with this. The switch is turned on and the lid closing detection signal is output to the control device, and as a result, the washing operation is started by the control device. Therefore, just by closing the lid after turning on the power, the washing operation starts automatically without requiring any special operation.
