A square hole 9 for inserting the guide claw 5 is provided in a mounting plate 8 fixed inside 7, and the rib 4 of the resin case 2 is inclined at a part of the periphery of the window hole 19 of the body outer plate 10 facing the rib 4. The inclined portion 13 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an operation unit such as a warm air heater.

[0002]

[Prior Art]

 As shown in FIG. 5, the conventional operation part structure of a warm air heater or the like is such that an operation unit 15 is configured by accommodating a switch substrate (not shown) in which a switch or the like is incorporated in a resin case 14 and constructing the operation unit 15. It was mounted on the mounting plate 16 inside the unit 7 with screws 17, and the front operating portion 18 was exposed to the window hole 19 provided on the outer plate 10 of the body 7.

[0003]

[Problems to be solved by the device]

 In this configuration, the operation unit 15 is a rigid body and does not move. Therefore, when it is attached to the mounting plate 16, it is difficult to assemble the periphery of the operation unit 15 and the window hole 19 provided in the outer plate 10 of the body 7 to be assembled uniformly. It was very unsightly in appearance.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned drawbacks, and a guide claw is provided on one part of the back side of the resin case, notches are provided on both sides of the claw, and a wedge-shaped rib is formed on the step of the peripheral side surface. The mounting plate fixed inside the body is provided with a square hole into which the guide claw is inserted, and the rib of the resin case is sloped around a part of the window hole of the body outer plate facing the rib. It is provided with a matching inclined portion.

[0005]

[Action]

 Notches are provided on both sides of the guide claws provided on the resin case to generate left-right movement, and by inserting this into the square holes of the mounting plate inside the body, vertical movement is provided. By aligning multiple wedge-shaped ribs around the case with the inclined part of the window hole formed in the outer plate of the body, the window hole and the resin case are automatically adjusted regardless of how the outer plate is set. It keeps the gap between the centering window hole and the resin case even.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4 in the drawings.

In the figure, reference numeral 1 denotes an operation unit, which is composed of a switch board (not shown) incorporating switches and the like and a convex resin case 2 accommodating the switch board, and has an operation portion 3 on the front surface. ing. Further, the operation unit 1 is provided with a plurality of wedge-shaped ribs 4 on the step portion on the peripheral side surface, a guide claw 5 on the longitudinal side surface on the back side, and a notch 6 so as to sandwich the guide claw 5 from both sides. , The strength of the guide claws 5 is weakened to facilitate the lateral movement. Reference numeral 7 is a body of the warm air heater, and a mounting plate 8 is fixed inside, and the mounting plate 7 is provided with a square hole 9 into which the guide claw 4 is fitted. The square hole 9 is formed larger than the guide claw 4 in the vertical direction, and when the guide claw 4 is inserted, the operation unit 1 can be moved in the vertical direction. Reference numeral 10 denotes an outer plate forming the front surface of the body 7, a window hole 11 is provided at a position where the operation portion 3 of the operation unit 1 faces, and a surrounding portion thereof has a return portion 12 and a rib provided on the operation unit 1. An inclined portion 13 matching the taper of 7 is provided.

According to the above configuration, when the outer plate 10 is assembled, the inclined portion 13 provided in the window hole 11 of the outer plate 10 can be operated even if the window hole 11 of the outer plate 10 and the operation unit 1 do not become concentric. The unit 4 comes into contact with the inclined portion of the wedge rib 4 of the unit 1, and the rib 4 automatically aligns the operation unit 1 and maintains a constant peripheral clearance between the operation unit 1 and the window hole 11 of the outer plate 10. .

[0009]

[Effect of the device]

 According to the present invention, the gap between the window hole of the outer plate and the periphery of the operation unit becomes constant, and there is an advantage that the appearance of the body can be improved.
