事が要求される。Conventional configuration and its problems Conventionally, in the operation button of this type of washing machine, electronic components 6, switches 7, etc. that constitute the operation control circuit of the washing machine are arranged, as shown in Figs. 1 and 2. The printed circuit board 8 is attached with screws 13 to the back side of a synthetic resin operation plate 4 which is fixed to the top plate 3 which is placed on the top of the outer box 2 of the washing machine with screws 5 and the like, and is pushed onto the operation plate 4. An actuating piece 9 that closes the contacts of the switch 7 by pressure operation is integrally formed as a resilient cantilever utilizing the characteristics of a synthetic resin material. A waterproof sheet 10 is attached, and a button shape is printed on the back side of the waterproof sheet at a position corresponding to the actuating piece 9, or a convex shape 14 of 31° is formed on the back side of the waterproof sheet. was giving. However, with this configuration, the force applied to the actuating piece 9 is applied by the user to the tarpaulin 10.
The force used to push the actuating piece 9 is almost equal to that of the switch 9, so if the user applies too much pushing force or accidentally bumps into it, a large pushing force or impact force will be applied directly to the switch 7, damaging it. Since impact force and strong force are also applied to the electronic components 6 and the printed circuit board 8 around the switch 7, these may be destroyed. Also, among the operation buttons of the washing machine,
A frequently used button, i.e. when starting the washing machine,
Buttons used to send signals to the operation control circuit or to turn off electricity when stopping or stopping are often subject to large pushing forces as described above, and the ease of pressing the buttons has also been improved. For this reason, buttons are required to be large in shape and easily noticeable.

かった。However, in the conventional configuration, it is necessary not only to enlarge the printing or convex shape corresponding to the button on the waterproof sheet 10 described above, but also to make the shape of the actuating piece 9 thicker accordingly. ff: Since it is constructed integrally with the operation plate 8 in the shape of a cantilever, the strength is about the same as that of the operation plate 8 with a cutout hole, so the disadvantage is that the size of the operation piece 9 cannot be made very large. Yes, so I couldn't make the buttons bigger.

A printed circuit board with a switch, etc. arranged thereon is attached, an actuation piece that closes the contacts of the switch by pressing operation is integrally formed, and the surface is covered with a waterproof sheet pasted on the actuation piece and its vicinity. The operating plate is disposed on a synthetic resin operation plate for the entire arrangement, and is provided with a convex portion that contacts the operating piece by 5" during normal operation (hereinafter referred to as normal operation) when no pressing operation is performed through the waterproof sheet roller, and , this convex portion rotates through the waterproof sheet to a position where the actuating piece is fully pressed, and immediately after the actuating piece is fully pressed (-), the portion other than the convex portion is rotated through the waterproof sheet. It comes into contact with the operation plate and stops the rotational movement.The configuration of this convex part allows
When the operation button is pressed strongly or when a shocking force is applied, the applied force causes the convex part to press the switch via the actuation piece due to the rotation of the operation button, but the contact of the switch After the button is closed, the part of the operation button other than the convex part comes into contact with the operation plate through the waterproof sheet and stops the rotation of the operation plate, so no further pressing pressure is applied to the switch.
It is absorbed into the operation panel and prevents damage to switches, electronic components, etc. and printed circuit boards. Also, it is the convex part that directly pushes the operating piece, so no matter how large the entire operating button is, there is no need to make the operating piece larger accordingly, and therefore the strength of the operating plate will not be compromised. By increasing the size, the ease of pressing the button can be improved.

、安全な大型操作釦を実現できる。By the way, even if the shape of the operation button is made thicker in order to improve the ease of push button operation, since it is the convex part that presses the actuation piece 9 of the operation plate 4, the actuation piece becomes larger as the shape of the operation button becomes larger. There is no need to increase the size, and the strength of the operation panel 4 is not impaired. Increasing the size of the operation button 11 tends to increase the pressing force applied to the operation button and the impact force of both barges. However, according to the present invention, the disadvantages of the conventional large pressing force and impact force can be eliminated. It is possible to realize a large and safe operation button.
