DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an electrical component unit such as an air conditioner.

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of an electrical component unit, an operation display unit is fixed at a predetermined position on the front side of a main body of an indoor unit, and a casing covering the front side of the main body is mounted on the main body. In the hole provided in the casing, the operation display unit switch, LED (light emitting diode)
Are fitted so that the switch can be operated while the casing is attached to the main body, and an LED display can be seen.

[0003]

However, in the mounting structure of the electrical component unit, since the relative positional accuracy between the casing and the main body is not sufficient, the switch and the LED of the operation display unit are provided in the holes provided in the casing. There is a problem that it is difficult to securely fit and align, and the workability is poor, and if the positions of the switches and LEDs of the operation display unit are shifted in a state of being fitted in the hole of the casing, the appearance is impaired. .

On the other hand, a switch of the operation display unit,
If the operation display unit is mounted not on the main body but on the casing in order to ensure that the LED is aligned with the hole of the casing, a new mounting member is required, resulting in a high cost.

[0005] In order to improve the aesthetic appearance even when the position of the switch of the operation display unit is deviated from the center of the hole of the casing, when the area provided with the hole of the casing is covered with a sheet-like cover, the cover is closed. There is a problem that the operability is poor because the switch of the operation display unit is pressed through the switch.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric component unit which can be easily adjusted to a predetermined position of a casing without deteriorating aesthetic appearance, thereby improving workability, and at the same time, having low cost and good operability. An object of the present invention is to provide a unit mounting structure.

[0007]

To achieve the above object, an electric component unit mounting structure according to claim 1 comprises a main body,
A casing attached to the front side of the main body, an electrical component unit attached to the front side of the main body so as to allow movement within a predetermined range, and at least partially fitted into a hole provided in the casing; And a guide portion provided on the back side of the casing and guiding the electrical component unit to a predetermined position of the casing when the casing is attached to the main body.

According to the mounting structure of the electric component unit of the first aspect, when the casing is mounted on the front side of the main body, the electric component unit mounted on the main body and allowed to move within a predetermined range is mounted on the main body. A guide portion provided on the casing smoothly and reliably guides the casing to a predetermined position. At least a part of the electrical component unit (for example, a protruding portion of the switch) guided as described above is securely fitted into the hole provided in the casing and the position is matched, so that the work of positioning is omitted and the workability is reduced. In addition to being able to improve the position, a part of the electrical component unit can be accurately positioned in the hole of the casing, and the appearance can be beautiful.

Further, since the electric component unit is mounted on the front side of the main body and guided by the guide portion, the cost can be reduced as compared with the case where the electric component unit is mounted on the casing using the mounting member.

In addition, since the electrical component unit can be accurately positioned by being guided by the guide portion, a sheet-like cover for covering the area provided with the hole of the casing is not required, and the operability of the switch and the like is reduced. The switch can be improved and a switch integrated with the switch cover can be used, so that the cover mounting step can be omitted, and the cost can be further reduced.
