Abstract

PURPOSE:To make it possible to open/close a switch lid without damaging a shaft or shaft hole even when the switch lid is tilted unnecessarily backward by a method wherein the title device is constituted in such a manner that a bearing part of a switch lid and a shaft of a top mark base can be detached by a designated external force. CONSTITUTION:For a switch lid 15, a notch part 16 is formed at a part of the rear edge, and at the same time, a bearing part 18 which forms an opening part 17 between the rear edge is provided. On both side wall parts at a rear part of a recessed part 20 of a top mark base 19, which confront with the bearing part 18, shafts 21 are projected, and they are rotatably fitted in the bearing part 18. By this method, when the switch lid 15 is tilted backward, the bearing part 18 receives function of leverage, and the opening part 17 is deflected to open, and the bearing part 18 can be detached from the shafts 21 smoothly. Therefore, trouble such as damage, etc., of the bearing part 18 or shaft 21 does not generate, and the switch lid 12 can be reset for reuse.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a lid device for a washing machine.

2. Description of the Related Art Conventionally, a lid device for a washing machine of this type has a structure as shown in FIGS. 6 to 8.

That is, the panel stand 2 is mounted above the outer tank 1.

A clothing input port 3 is formed in this panel stand 2.

A storage section 4 is disposed in a part of the panel stand 2, and the storage section 4 is covered from above and has a button 6.
A top mark board 7 is provided with an operation panel 6 mounted thereon. On the back side of this top mark board 7 is a switch 8.
A printed circuit board unit 9 having control equipment of v is installed. A recess 10 on which a second operation plate 11 is attached is formed in a part of the top mark board 7, and a switch lid 12 is rotatably supported so as to cover the recess 10. A shaft hole 13.13 is arranged in a part of the shaft hole 13.
11114114' is formed integrally with the switch lid 12.

Problems to be Solved by the Invention As mentioned above, the switch cover 12 provided on a part of the top machining board 7 of the washing machine has a switch cover 12 provided on a part of the rear part of the recess 1o about the shaft 14.14. However, if the switch cover 12 is pushed further backward with the switch cover 12 in the open state, the shaft 14° 14 may be damaged or the top mark board 7 may be damaged. Problems such as deformation and damage of the shaft hole 13°13 occurred. This is the rear part of the recess 10 and the switch cover 12.
This is due to the shear load that occurs when the switch cover 12 is tilted backwards using the part where it touches a part of the 0 surface as a fulcrum. The action remains the same, but on the other hand, since there is less bending, the opening/closing operation becomes unstable, making it easier for shafts 13 and 13 to come off, and the tip of the shaft becomes more sagging.
It lacked reliability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to enable reliable opening and closing operations of the switch cover without damaging the shaft or the shaft hole even if the switch cover is tilted backwards more than necessary.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a top mark board that houses control equipment such as switches and is equipped with an operation panel having buttons, etc., and a top mark board that covers the top mark board. , a switch lid provided with a bearing part, and a structure in which the shaft part installed on the top mark board and the bearing part are detachably attached.

Function: In the washing machine lid device of the present invention, when the switch lid is opened with the above configuration, the switch lid is fitted with the shaft of the top mark board at the bearing portion, so that the switch lid can be rotated reliably. However, when the switch lid is further tilted backwards, an action based on this principle occurs in the bearing part using the contact area (1st Nd) between a part of the surface of the switch lid and a part of the four rear parts of the top mark board as a fulcrum. Then, the bearing part is removed from the shaft, and the switch cover can be reattached and used again without damaging the shaft, bearing part, etc.

In addition, when the bearing part is attached to the switch cover using a claw part (Fig. 6), even if the switch cover is tilted back more than necessary as shown above, the external force will cause the claw to separate from the shaft support, causing the shaft and There will be no damage to the bearing.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6. Note that structural description of parts that overlap with those of the conventional example will be omitted.

In the figure, 16 is a switch lid, with a notch 1 on a part of the rear edge.
6.16 and an opening 17 between the trailing edge and the trailing edge.
．． A hook-shaped bearing part 18.18 is provided, which is formed with a diameter 17'. A shaft 21.
21' is provided in a protruding manner, and the bearing parts 18 and 18' are rotatably fitted therein.

Further, the opening 17.17 of the bearing portion 18.18 is 111
121121, and is press-fitted onto the shaft 21° 21 by utilizing the deflection of the switch lid, which is made of a flexible material such as synthetic resin. It is.

At one end of the shaft 21, 21' there is a stopper part 22.
' are connected to increase the strength of the shaft 21, 21', and to engage with the notch 16° 16 when the switch cover 16 is opened.

Further, in the embodiment shown in FIG.
When the switch cover 16 is tilted backward and excessive force is applied, the pivot support 24 remains rotatably attached to the shaft 21 of the top mark board 19, and the switch cover 1
Only 6 can be removed by the claw portion 23.

From the above embodiments, the hook-shaped bearing portions 18 and 18' provided at the rear of the switch lid 16 have openings 17° and 17'.
, and the shaft 21.21' portion is connected to the bearing portion 18°18'.
By fitting the switch cover 15 so that it can rotate freely, even when the switch cover 15 is tilted backward, the bearing part 18.18 is levered and the opening part 17.17 is flexed to open. 21, 21', and the bearing parts 18, 18'
The switch cover 16 can be fitted and set again and used without any problems such as breakage of the shafts 21 and 21'.

In addition, by forming the shaft horn (part 22, 22'), the shaft 21° 21' is reinforced, and when the switch lid 16 is opened, the switch lid 15 is engaged with a part of the switch lid Without damaging the surface of the lid 160,
In addition, since the bearings 18 and 18' are provided near the bearings 18 and 18', even if the bearings 18.18 and the shaft 21.21' are strained by the external force of the switch lid 16, they will not be deformed and the bearings will be securely connected. 1 B, '1 B' can be attached and detached.

In addition, by dividing the stem cover 15 into two parts, it is possible to form the stem cover 15 from different materials. For example, bearing portion 18
．． The shaft support 24 having the bearing part 18 has improved rigidity.
8 and 18', or by changing the color and making the switch cover 16 side translucent so that the display can be seen through.

Effects of the Invention As is clear from the description of the embodiments above, the present invention is configured so that the bearing portion of the switch lid and the shaft of the top mark board can be attached and detached by a predetermined external force, so that the switch lid can be attached and removed more easily than necessary. Even if the switch cover is tilted backwards, the switch cover can be easily removed from the board due to the force caused by the excessive tilt, and the switch cover can be opened and closed reliably without deforming or damaging the shaft or shaft hole.
