Description

TECHNICAL FIELD The present invention relates to an operating device provided with a plurality of push button switches inside a casing.

[Prior Art] For example, in an automatic gas water heater, a remote controller is provided in a kitchen or bathroom away from a control device that controls the operating state of the water heater, and the hot water temperature can be set by a switch on the remote controller. , You will be given instructions to automatically fill the water.

In such an operating device, as shown in FIG. 10, inside of a casing 60 formed by fitting two resins to each other, in order to set a hot water temperature, a hot water filling time, or to give an operation instruction, respectively. Multiple switches with functions
61 is provided, and each switch 61 is provided on the surface of the casing 60.
In order to operate the
Push buttons 63 are formed in the openings 62 respectively, and when each push button 63 is pressed, a switch 61 corresponding to the push button 63 is operated by a protrusion 64 of the push button 63.

In this case, in order to prevent the push buttons 63 from coming off the casing 60, the opening 62 on the surface of the casing 60 is covered with the push buttons 63 by the sealing members 65 and 66.

[Problems to be Solved by the Invention] In such a conventional operating device, when assembling the operating device, a push button for operating the switch has to be fitted into each opening in accordance with the number of switches. More and more difficult to assemble,
There is a problem that the management is troublesome because each push button is required corresponding to the number of switches.

According to the present invention, in an operating device in which a plurality of push button switches are provided inside a casing and an operating member for operating the switches is provided on the surface of the casing, the assembling property is improved and a large number of switches are provided. Even in such a case, it is intended to suppress an increase in the burden of managing the operation members of the switch.

[Means for Solving the Problem] The present invention is provided with a plurality of push button switches for emitting an operation signal to a control device for controlling a device inside a casing, and the casing corresponds to the plurality of push button switches. Forming a plurality of openings, and a plurality of switch operating members for operating the plurality of push button switches are arranged to penetrate through the plurality of openings, and the switch operating members are covered with the casing by a seal member. In an operating device equipped with a broken push button switch,
A technical means is that a groove portion connecting the plurality of openings is formed on the surface of the casing, and the switch operating member is integrally formed with a connecting member arranged in the groove portion.

[Operation] In the present invention, since the switch operating member for pressing the push button switch is integrally formed with the connecting member, when the switch operating member is arranged and assembled in the casing, the connecting member is irrespective of the number of switches. Each switch operating member for operating a plurality of switches can be arranged in the opening only by aligning the switch with the groove.

Further, since the switch operating member is integrated by the connecting member, it is not necessary to handle small members such as individually formed push buttons, and therefore the switch operating member can be handled easily.

Therefore, even if many switches are provided, the labor of assembling is not proportional to the number of switches, and the switch operating members corresponding to a certain number of switches can be assembled at the same time, so that the assembling property is improved. Also, in managing parts, since it is not necessary to handle many small parts such as push buttons, the management load is reduced.

Further, if the intervals between the switches are set to be constant, a large number of switch operating members are continuously integrated to form the necessary switch operating members according to the number of switches. It is also possible to use the connecting member by cutting it halfway.

[Effects of the Invention] In the present invention, since the plurality of switch operating members are integrally formed with the connecting member, when arranging the casing, the switch operating members corresponding to several switches at one time are arranged in each opening. be able to.

Even if the number of switches is large, the number of individual switch operating members does not increase correspondingly, and the number of parts can be reduced, which simplifies the management of parts and increases the burden on them. There is nothing to do.

Furthermore, depending on the arrangement and spacing of the switches, switch operating members can be formed so that they can be used for multiple types of casings simply by cutting them, and the management of parts can be simplified. However, it will be easier to deal with it.
