Abstract

PURPOSE:To prevent damage of a preliminary drive/stop switch when an impact force is operated at an air conditioner by disposing an end of an operating protrusion of the switch inside from an inner surface of a hole of a front panel. CONSTITUTION:An end of an operating protrusion 3 of a preliminary drive/stop switch 4 is disposed about 1.5mm inside of an inner surface of a hole 11 of a front panel 7. The hole 11 is so formed in a diameter of about 15mm as to insert a human finger. E A reinforcing rib 12 which is gradually increased in width from its top to a base is formed on an inner surface of one sidewall 6B of a U-shaped holding frame 6. The rib 12 may be not only one but also two or more, or may be provided on an inner surface of the other sidewall 6A. The rib may be formed only at bases of the sidewalls 6A, 6B. Thus, even if an impact force is applied, the protrusion of the switch is not brought into contact with the panel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted air conditioner having a preliminary start / stop switch.

[0002]

2. Description of the Related Art A wall-mounted air conditioner is installed on an upper wall of a room as shown in FIG. 2 and is usually remotely controlled by operating a remote controller 2. However, when the remote controller 2 cannot be used. Preliminary operation / stop switch 4 that is manually operated in an emergency
Is provided in the main body 1 of the air conditioner.

This preliminary operation / stop switch 4 is shown in FIG.
As shown in FIG. 3, the operation protrusion 3 mounted on the switch substrate 5 penetrates through an elongated hole 8 provided in the front panel 7 and projects forward. The switch board 5 has protrusions 5A and 5B provided at both ends thereof on both side walls 6A of the U-shaped holding frame 6,
By being inserted into the hole 9 provided at the tip of 6B, the elastic force of the side walls 6A and 6B is retained. The U-shaped holding frame 6 is fixed to the control box 10 which is fixed inside the main body 1.

[0004]

In the above-mentioned conventional air conditioner, the front panel 7 has the elongated hole 8 due to the impact force due to its vibration, drop, and fall during the process of transporting the air conditioner from the factory to the market. If it shifts in the direction of the minor axis, the tip of the operation protrusion 3 of the preliminary operation / stop switch 4 becomes the elongated hole 8.
There is a risk that the operation projection 3 may be damaged by coming into contact with the edge of the.
Further, since the elastic repulsive force of the U-shaped holding frame 6 is weak, there is a problem that the projections 5A and 5B of the switch substrate 5 come out of the hole 9 and fall off when an impact force is applied.

[0005]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to provide a wall-mounted air conditioner that is remotely controlled by operating a remote controller. In a wall-mounted air conditioner that has a preliminary operation start / stop switch mounted on the switch board that is built in and fixed to the main body of the main body, and this operation protrusion is operated through the hole provided on the front panel. There is provided a wall-mounted air conditioner characterized in that the tip of a switch operation protrusion is located inside the hole of the front panel from the inner surface thereof.

The protrusions provided at both ends of the switch board are inserted into the holes provided at the tips of both side walls of the U-shaped holding frame fixed to the control box, and are held by the elastic repulsive force of these both side walls. Reinforcing ribs can be formed on one or both walls.

[0007]

In the present invention, the operation protrusion of the preliminary operation / stop switch does not come into contact with the hole of the front panel due to impact force or the like.

Further, since the elastic repulsive force of the U-shaped holding frame is enhanced by the reinforcing ribs, the switch substrate does not fall off the U-shaped holding frame.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. As shown in FIG. 1 (A), the tip of the operation protrusion 3 of the preliminary operation / stop switch 4 is located inside the hole 11 of the front panel 7 and about 1.5 mm inside from the inner surface thereof. Note that hole 11
Has a circular shape with a diameter of about 15 mm so that a human fingertip can be inserted.

A reinforcing rib 12 is formed on the inner surface of one side wall 6B of the U-shaped holding frame 6 so that the width gradually increases from the top to the base. Although only one reinforcing rib 12 is shown, it may be two or more, and may be provided on the inner surface of the other side wall 6A. Further, the reinforcing rib 12 may be formed only on the base side of the side walls 6A and 6B. Other configurations are similar to those of the conventional one shown in FIG. 3, and corresponding members are designated by the same reference numerals.

When it is necessary to operate the preliminary operation / stop switch 4, the fingertip may be inserted through the hole 11 and the tip of the operation projection 3 may be pushed down.

Since the tip of the operation protrusion 3 is located inside the inner surface of the front panel 7, the front panel 7 and the preliminary operation / stop switch 4 are separated by the impact force applied to the air conditioner. Even if there is a gap between them, the operation protrusion 3 does not come into contact with the edge of the hole 11, so that the preliminary operation / stop switch 4 is not damaged.

Further, since the reinforcing rib 12 is formed on one or both of the side walls 6A, 6B of the U-shaped holding frame 6, the elastic repulsive force of the side walls 6A, 6B is increased. Therefore, it is possible to prevent the protrusions 5A and 5B of the switch substrate 5 from coming out of the hole 9 and coming off even when vibration or impact is applied.

[0014]

According to the present invention, since the tip of the operation projection of the preliminary operation / stop switch is positioned inside the hole of the front panel inside the inner surface thereof, the preliminary operation is prevented even when an impact force is applied. Since the operation protrusion of the start / stop switch does not come into contact with the hole on the front panel, it is possible to prevent damage to the preliminary start / stop switch.

Further, since the elastic repulsive force of the side wall of the U-shaped holding frame is enhanced by the reinforcing ribs, it is possible to prevent the switch substrate from falling off the U-shaped holding frame.
