Further, when the controller 2 is provided near the front upper part of the washing machine, for example, when the remaining hot water in the bath is used for rinsing, the remaining hot water is pumped up by a bucket and put in the washing tub, the controller 2 If water is splashed on the upper surface of the top cover 1 that accommodates the water, the water may reach the controller 2, and the waterproof structure must be completed.

The object of the present invention is to further improve the operability of the switch operating portion as compared with the conventional one, and at the same time, to shorten the wiring and to rationalize it. In addition, the waterproof structure of the controller accommodating portion is rough. It is an object of the present invention to provide an improved washing machine that can achieve all kinds of good effects at the same time.

[0025]

Means for Solving the Problems The above-mentioned object is to provide an operation switch section for an operator to instruct the operation content of a washing machine from the outside,
In a washing machine having a top cover with a controller for controlling the operation of the washing machine, the operation switch section and the controller are set in a separate state due to their mounting structure, and the operation switch section is attached in front of the top cover, and the controller is attached to the top cover. This is achieved by incorporating it in the rear of the.

[0026]

According to the present invention, the operating switch section of the washing machine and the controller are separated from each other due to their mounting structure,
