Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device having a control unit such as a washing machine.

2. Description of the Related Art Conventionally, a mounting device for this type of manufacturing unit is shown in FIGS.
The structure was as shown in the figure.

That is, the operation plate 17 has a substantially R shape such as a streamlined shape, and the control device unit mounted inside the operation plate 17
The configuration of 18 is a plurality of LEs which are formed close to the surface of the operation plate 17 and whose upper surface is formed with an equivalent curvature R that should follow the substantially R shape of the operation plate 17.
The D block 19 is arranged and mounted on a substantially flat printed circuit board 20.

However, with such a structure, as shown in FIG. 4, it is necessary to form the LED block 19 so as to follow the curvature R shape of the operation plate 17, and the terminal 22 of the LED lamp 21. LED block 19 and LED lamp 21
The number of types of parts has increased, and when the LED lamp 21 was incorporated into the LED block 19, it became complicated and caused a part failure such as a mistake in insertion.

Also, each time the product design was changed, a dedicated LED block 19 had to be renewed, which was expensive.

Furthermore, the LED block 19 that does not follow the curvature R of the operation plate 17
When set to, unbalanced brightness was obtained due to the size of the gap between the LED lamp 21 and the operation plate 17.

Therefore, an object of the present invention is to provide a mounting device for a control unit that does not need to be compatible with the shape of the LED block or the LED lamp even when the operation plate has a curvature R.

Means for Solving the Problems And, in order to achieve the above object, the present invention provides a control unit in which a switch, an LED lamp, and the like are mounted on a substantially flat printed circuit board, an operation plate having a push button, and the like. A holding plate having guide ribs or the like formed with an equivalent curvature R that should follow the substantially R shape of the plate is provided, and a control unit is interposed inside the operation plate, and the holding plate serves as the control plate of the operation plate. The urging force should be kept along the R shape.

The mounting device of the control unit of the present invention has the above-described structure, and uses the LED lamp having a constant height, and corrects the LED lamp into a shape that should follow the curvature R of the operation plate by the guide ribs of the holding plate. Can be arranged on the surface of the operation plate at regular intervals without increasing the number of parts, and when the design is changed, only the curvature R of the holding plate needs to be changed, and the mounting device can be manufactured at low cost.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3, the operating unit of the washing machine is shown, in which 7 is an outer tub, 8 is a main body cover to which the upper opening of the outer tub 7 is to be covered, and the operating unit is located in the front. At the center, there is provided a lid 10 which is rotatably supported and an inlet 11 for clothes and the like.

Reference numeral 1 denotes an operation plate having a substantially R shape in the vertical direction and a substantially R shape in the horizontal direction as shown in FIG.
It is mounted so as to cover the opening. 2 is the operation unit 9
The first control equipment unit housed inside the jumper wire
It is connected via 12 to a second control unit 2 '.

The first control device unit 2 and the second control device unit 2'oppose the wiring-processed pattern surface of the printed circuit boards 4, 4'and are formed of an insulating material for preventing electric leakage. A holding plate 13 is interposed, and is sandwiched by a plurality of bosses 14 projectingly formed on the rear surface of the operation plate 1 with screws 15. At this time, the holding plate 13 is provided with a guide rib 16 formed in a substantially R shape so as to follow the curvature R of the operation plate 1, and is formed in a substantially flat shape so as to be biased by the guide rib 16 for correction. The printed circuit board 4 is attached to the rear surface of the operation plate 1 in a state where the printed circuit board 4 is formed in a substantially R shape.

That is, since the printed circuit boards 4 and 4 ′ themselves are corrected at the time of assembling, when assembling as a control device unit, it suffices to arrange a plurality of uniform LED blocks 3 having a constant upper surface. The terminal 6 of the LED lamp 5 can also be composed of uniform parts.

Further, the holding plate 13 has the same effect as the present invention even in the case where a flat portion is formed on the upper surface side of the guide rib 16 or the guide rib or the like is eliminated by changing the thickness of the substrate itself of the holding plate 13. Can be raised.

The control device unit mounting surface of the boss 14 is formed with a curvature R substantially equal to that of the operation plate 1. Also, 17 is a switch and 18 is a button.

As described above, according to the present invention, since the holding plate is biased so as to follow the curvature R of the operation plate, the parts can be simplified without changing the heights of the LED lamp and the LED block. It is possible to rationalize the assembly.

Also, when the curvature R is changed by changing the design etc., it can be easily dealt with by changing the holding plate, which is inexpensive and has a structure in which the curvature R of the operation plate is evenly distributed and the brightness of the LED lamp is constant. It can be done.
