Abstract

(57) [Summary] [Purpose] The switch unit faces the opening of the outer plate.
In the case of operating the switch in the switch unit by pushing the operation panel attached to the switch unit, when the operation panel is pushed, a strong force is applied to the switch, the switch breaks down, or the board on which the switch is attached causes the pattern to come off. The present invention aims to solve the above drawbacks. [Structure] The outer plate 2 facing the switch 8 of the switch unit 5 is provided with an operation hole 16 corresponding to the size of a finger, and an operation panel 17 is attached to the front face of the outer plate 2 facing the switch unit 5, A convex seat pusher 18 is provided at a portion of the panel 17 facing the operation hole 16. [Effect] Even when the convex seat pusher 18 of the operation panel 17 is pushed, the switch 8 does not receive a certain force, so that the switch does not break down or the substrate does not come off the pattern.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a configuration of an operation unit incorporated in a warm air heater or the like.

[0002]

[Prior Art]

 The configuration of a conventional operation unit of this type will be described with reference to FIGS.

In the figure, reference numeral 1 is a body, 2 is an outer plate which constitutes a front plate of the body 1, and an opening 3 for exposing an operation panel 14 of a switch unit 5 described later is provided in a part thereof. Reference numeral 4 denotes a switch mounting plate, which is mounted on the front side inside the body 1 with the outer plate 2 at a constant distance. Reference numeral 5 denotes a switch unit for operating and adjusting the body 1, which includes a resin case 6, a board 7 disposed in the resin case 6, a switch 8 and an LED 9 incorporated on the board 7. It is configured and fixed to the switch mounting plate 3 so as to face the opening 3 of the outer plate 2.

Further, a spacer piece 11 for pressing the peep hole 10 of the LED 9 and the switch 8 is provided on the outer plate 2 side of the resin case 6, and the spacer piece 11 is integrally molded with the resin case 5 to form a part. A thin portion 12 is formed on the upper end of the thin portion, and a pushing portion 13 is formed on the tip.

Reference numeral 14 denotes a resin operation panel attached to the front surface of the switch unit 5, and has a convex seat pusher 15 at a portion facing the switch 8.

[0006]

[Problems to be solved by the device]

 In the above-mentioned conventional product, when the convex seat pusher 15 of the operation panel 14 is pressed, the deflection 9 of the spacer 11 is large and a strong force is applied to the switch 8, and the switch 8 breaks down or the board 7 is patterned while the number of operations is small. There was a defect such as causing disconnection.

As a countermeasure against this, there is a method in which a pole 16 is provided inside the spacer piece 11 as shown by a dotted line so that a certain amount of force is not applied to the switch 8 and the substrate 7 by the pole 16. Even so, when a strong force such as a child is applied from the operation panel 14, there is a drawback that it cannot cope with it sufficiently.

Further, since the switch unit 5 is exposed to the opening 3 of the outer plate 2, it is difficult to finish the gap H between the two uniformly and to improve the appearance.

[0009]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned drawbacks.Specifically, an operation hole corresponding to the size of a finger is provided on the outer plate facing the switch of the switch unit, and the switch unit and An operation panel is attached to the front surface of the facing outer plate, and a convex seat push is provided on the part of the panel facing the operation hole.

[0010]

[Action]

 According to the above structure, even if the pushing force of the convex seat of the operation panel is pressed with a strong force, the operation hole of the outer plate that fits the size of the finger does not apply a certain force or more to the switch via the spacer piece. It is possible to prevent the switch and the board from being damaged.

Further, since the outer plate has only the operation hole, and this hole is also closed by the operation panel, the appearance of the outer plate is not spoiled unlike the conventional case.

[0012]

【Example】

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

In FIGS. 1 and 2, only the differences from FIGS. 3 and 4 will be described. The outer plate 2 facing the switch 8 of the switch unit 5 is provided with an operation hole 16 that is approximately the size of a finger. It has been set up.

A resin operation panel 17 is attached to the front surface of the outer plate 2 facing the switch unit 5, and a convex seat pusher 18 is provided at a portion of the panel 17 facing the switch 8. There is.

Since the other configurations are the same as those in FIGS. 3 and 4, description thereof will be omitted.

According to the above configuration, even if a strong force of a certain amount or more is applied to the convex seat pusher 18 for operating the switch 8 of the switch unit 5, the operation hole 16 of the outer plate 2 raises the finger above a certain amount. Since no force is applied to the switch 8, the switch 8 does not break down or the substrate 7 does not come off the pattern.

[0017]

[Effect of the device]

 As described above, according to the present invention, since the operation plate is provided with an operation hole corresponding to the size of a finger on the outer plate facing the switch, and the operation hole is covered with the operation panel, the switch has a certain amount or more. The switch will not fail or the board will not come off the pattern due to the force not applied.

Further, since the outer plate is not provided with the opening for facing the switch unit as in the conventional case, the appearance does not become unsightly.
