Abstract

An electric device including a push button switch that is less likely to break down is provided.
A container body 7a forming an outer shell and a push button switch 30 for controlling an electric load 26 are provided. The push button switch 30 protrudes from a hole 8 provided in the container body 7a and is pressed from the outside. A button 9 to be operated, a flange 10 formed horizontally extending over the entire circumference of the base of the button 9, and a guide wall 12 formed vertically on the outer periphery of the flange 10 and provided with an opening 11 in part. Since the water flowing into the container body 7a is accumulated in the flange 10 and the guide wall 12 and flows only from the opening 11 of the guide wall 12, the flow path of the water can be regulated. It is possible to prevent water from reaching the shaft support portion 14 that slidably supports 9a.

Description

  The present invention relates to an electric device such as a cooking device used at home and the like, and more particularly, to a waterproof structure of a push button switch used in the electric device.

  Push button switches used in conventional electrical equipment are provided with a flange that protrudes horizontally around the base of the button, so that water enters the body from the hole of the body where the push button switch is attached and the gap between the buttons. The foreign material is configured to be difficult to enter (for example, see Patent Document 1).

FIG. 4 shows an example of a conventional push button switch of an electric device disclosed in the above-mentioned Patent Document 1. A horizontally projecting flange 2 is provided around the root of the button 1, and the flange 2 Water or the like is prevented from entering the body 3 from the gap 4 between the hole 3 of the device body and the button 1.
Japanese Utility Model Publication No. 62-45624

  However, according to the configuration of the push button switch of the conventional electric device, a part of the water that has entered the vessel body 3 is placed on the shaft support 6 that slidably supports the shaft 5 to which the button 1 is attached. As a result, there is a problem that the operation of the shaft 5 becomes unsatisfactory, or water enters the inside of the push button switch from the shaft support portion 6 and the electric device breaks down.

  An object of the present invention is to solve the above-described conventional problems, and to provide an electric device that prevents water that has entered the body from reaching the shaft support portion and is less likely to fail.

  In order to solve the above-described conventional problems, an electrical device of the present invention includes a container that forms an outer shell and a push button switch that controls an electrical load, and the push button switch includes a hole provided in the container. A button that protrudes from the outside and that is pushed from the outside, a flange that extends horizontally over the entire circumference of the base of the button, and a guide wall that is vertically formed on the outer periphery of the flange and has an opening in a part thereof The flow path of water can be regulated by accumulating water that has entered the container inside the flange and the guide wall and flowing only from the opening of the guide wall, so that the shaft with the button attached is slidably supported. It is possible to prevent water from reaching the shaft support portion.

  The electrical device of the present invention can regulate the flow path of water by accumulating water that has entered the inside of the container in the flange of the push button switch and the guide wall and flowing only from the opening of the guide wall. It is possible to prevent water from reaching the shaft support portion that supports the shaft of the button.

  1st invention is equipped with the container which forms an outer shell, and the pushbutton switch which controls an electric load, The said pushbutton switch protrudes from the hole provided in the said container, and is pressed from the outside And a flange formed horizontally extending over the entire circumference of the base of the button, and a guide wall formed perpendicularly to the upper periphery of the flange and provided with an opening in a part thereof. Since the flow path of water can be regulated by storing the gas in the flange and the guide wall and flowing only from the opening of the guide wall, water can reach the shaft support part that slidably supports the shaft to which the button is attached. Can be prevented.

  In the second invention, in particular, an annular rib is suspended from the inner surface around the hole of the container of the first invention, and the annular rib is positioned inside the guide wall. Even if water intrudes into the body through the gap between the button and the button, the water is weakened before reaching the guide wall by the annular rib, making it difficult for the water to pass over the guide wall, so that It can be prevented from entering.

  In the third invention, in particular, at least at the bottom dead center of the stroke of the button, the annular rib and the guide wall overlap in the vertical direction. Even when water intrudes into the body vigorously, the annular rib overlapped with the guide wall weakens the water and prevents the water from passing over the guide wall. Can be prevented from entering.

  In the fourth invention, in particular, the flange is inclined so that the opening of the guide wall of any one of the first to third inventions is lowered, and the water accumulated in the flange and the guide wall is guided quickly. Can flow from the opening in the wall.

  In particular, the fifth invention has a flange connected to the opening of any one of the first to fourth inventions and an extension part extending the guide wall, and the water stored in the flange and the guide wall is It is possible to prevent water from entering the shaft support portion of the button by draining from the opening of the guide wall at a position farther from the shaft support portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1A is a cross-sectional view (“OFF” state) of the electric device according to Embodiment 1 of the present invention, FIG. 1B is a plan view of the push button switch of the electric device, Sectional drawing (the "on" state) of the principal part of the electrical equipment, (b) is a plan view of the push button switch.

  1 and 2, reference numeral 7 denotes an electric device according to the present embodiment, which is a container 7 a that forms an outline and has a hole 8, a push button switch 30 that has a button 9 that is pushed from the outside, and a push button. An electric load 26 controlled by the button switch 30 is provided.

  The push button switch 30 is attached to the container body 7a so that the tip of the button 9 protrudes from the hole 8 provided in the container body 7a. A flange 10 extending horizontally is provided on the entire periphery of the base of the button 9, and a vertical guide wall 12 having an opening 11 is provided on the outer periphery of the flange 10.

  A vertical annular rib 13 is provided on the inner surface around the hole 8 provided in the vessel body 7, and this annular rib 13 is disposed inside the guide wall 12 provided in the push button switch 30. The annular rib 13 and the guide wall 12 overlap in the vertical direction at the bottom dead center of the stroke of the button 9.

  As described above, according to the present embodiment, the water that has entered the container body 7 through the gap between the hole 8 and the button 9 is accumulated in the flange 10 and the guide wall 12, and from the opening 11 of the guide wall 12, Since the shaft 9a to which the button 9 is attached is slidably supported from the shaft support portion 14 that slidably supports, it is possible to prevent water from reaching the shaft support portion 14. Even if a liquid such as water invades, the water is weakened before reaching the guide wall 12 by the annular rib 13 overlapped with the guide wall 12, so that the water is guided by the guide wall 12. It is possible to provide an electric device which does not enter the shaft support portion 14 of the paste over button 9 and is less likely to break down.

(Embodiment 2)
FIG. 3A is a cross-sectional view of an essential part of an electric device according to Embodiment 2 of the present invention, and FIG. 3B is a plan view of a push button switch of the electric device.
