JPH0556091U - Electric washing machine operation panel waterproof device - Google Patents

Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide an operation panel waterproofing device that solves the problem that the switch becomes inoperable due to intrusion of water or the like in the operation panel of an electric washing machine. [Structure] A film sheet 9 is welded to the operation panel 2,
In addition, since the decorative sheet 8 is adhered onto the film sheet 9, water or the like can be prevented from entering the film sheet 9 even if the decorative sheet 8 is peeled off by an operation. It is possible to obtain a highly reliable operation panel waterproof device that does not fail.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a waterproof device for a panel operation unit of an electric washing machine.

[0002]

[Prior Art]

 In recent years, there has been an increasing demand to solve the problem of inoperability due to poor waterproofing of the panel operating unit of electric washing machines.

A conventional waterproof device for a panel operating portion of an electric washing machine will be described below. 5 and 6 show the configuration of a conventional panel operation unit. As shown in FIGS. 5 and 6, the operation panel 2 mounted on the upper body 1 of the electric washing machine is integrally formed with the button portion 3, and the button portion 3 is provided with the spiral slit 3a in the operation panel 2 portion in the periphery. It has elasticity. A switch 5 is mounted on the substrate 4 facing the operation panel 2, and switch contacts 7a and 7b mounted on the substrate 4 are provided below the cap 6 of the switch 5. Further, a decorative plate 8 displaying the operation section is adhered to the surface of the button section 3 of the operation panel 2.

The operation of the panel operation unit configured as described above will be described below. As shown in FIG. 7, when the upper portion of the button portion 3 of the decorative plate 8 is pushed with a finger, the button portion 3 is pushed down, and the switch contact pieces 7 a and 7 b come into contact with each other via the cap 6 to be in a conductive state.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, as shown in FIG. 7, when the decorative plate 8 on the upper part of the button portion 3 is pushed down, the adhesive part is peeled off due to the deformation of the decorative plate 8. Had entered the substrate 4 and accumulated on the substrate 4 to cause a decrease in leakage between the switch contact pieces 7a and 7b, resulting in inoperability.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a waterproof device for an operation panel in which water does not enter the switch section.

[0007]

[Means for Solving the Problems]

 In order to achieve this object, the waterproof device for an operation panel of the present invention has a structure in which a decorative plate is adhered onto a film sheet that is welded to the operation panel.

[0008]

[Action]

 With this configuration, since the film sheet is welded to the operation panel even if the decorative plate is peeled off, it is possible to prevent water from entering the switch section.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 1 and 2, a film sheet 9 is welded to the operation panel 2, and a decorative plate 8 is adhered thereon. The film sheet 9 is welded by ultrasonic welding using a welding horn 10 and a pedestal 11 on a rib 2a provided around the button portion 3 of the operation panel 2 as shown in FIG. It is welded around the circumference.

It should be noted that the film sheet 9 made of the same material as the operation panel 2 has good weldability, and the film sheet having a thickness of about 0.2 mm does not have a large pressing force and will not be torn.

Further, the film sheet 9 can be formed at the same time when the operation panel is formed, and the welding process can be omitted.

The operation of the panel operation unit configured as described above will be described with reference to FIG. When the upper portion of the button portion 3 of the decorative plate 8 is pushed with a finger, the button portion 3 is pushed down, and the switch contact pieces 7a and 7b come into contact with each other via the cap 6 to establish a conductive state.

As described above, according to this embodiment, the decorative sheet 8 is adhered to the operation panel 2 by welding the film sheet 9 on the operation panel 2, and the decorative sheet 8 is deformed by being pressed by a finger. Even if the portion is peeled off, the film sheet 9 can prevent water and the like from entering.

[0015]

[Effect of the device]

 As is apparent from the above description of the embodiments, the present invention inserts a film sheet between the operation panel and the decorative plate and welds the operation panel to remove the adhesion between the decorative plate and the film sheet. The film sheet prevents entry of water or the like, and realizes an excellent operation panel waterproofing device for an electric washing machine in which water or the like does not enter the contact piece of the switch to make it inoperable.
