In this type, since the upper end and the lower end are respectively locked, when an unreasonable force is applied to the indoor unit, the mounting plate may bounce and the indoor unit may come off the mounting plate. is there. Therefore, conventionally, various types of detents have been adopted so that the indoor unit does not come off from the mounting plate even if an unreasonable force is applied to the indoor unit up and down.

Further, since the indoor unit has a built-in heat exchanger, a drain pan and a drain receiver are provided to collect the drain generated in the heat exchanger and the drain attached to the indoor unit.

Although the drain receiver extends in the longitudinal direction of the indoor unit, the drain receiver may be inclined in a predetermined direction in order to guide the drain in a predetermined direction.

When fixing such an indoor unit to the wall surface, it is not necessary that at least the predetermined direction is raised.
In that case, the mounting plate that is screwed to the wall surface must be screwed so that the predetermined direction does not rise even if it is wrong.

However, as the first problem, the conventional retaining means for retaining the indoor unit has a complicated structure, and since the upper end portion and / or the lower end portion are devised respectively, the detachment is prevented. There is a problem that the effect of stopping is weak.

In the second problem, the work of attaching the attachment plate to the wall surface depends on the sense of the operator, and the case where the attachment plate cannot be attached so that the predetermined direction does not rise. Can also happen.

The present invention has been made in order to solve the above-mentioned problems, and provides a mounting device having a simple structure and capable of securely fixing an indoor unit as compared with the conventional one, and further, a predetermined device. An object of the present invention is to provide an air conditioner mounting device capable of mounting an indoor unit in a state in which the direction is lowered.

[0010]

In order to achieve the above-mentioned object, the present invention relates to an indoor unit by locking the upper end and the lower end of the indoor unit to the upper end and the lower end of the mounting plate, respectively. In the fixing device of the air conditioner to be fixed, a notch is provided in the middle of the mounting plate, and a projection that is fitted into the notch is provided on the rear panel of the indoor unit. is there.

Further, according to the present invention, in the above-described air conditioner mounting device, the mounting plate is provided with a plurality of holes for passing screws, and one of the holes is a substantially perfect circle or a horizontally long hole. The other hole is a vertically long hole.

[0012]

According to the present invention, since the projection is fitted in the notch, the indoor unit is supported not only at the upper and lower ends but also in the middle, so that an unreasonable force is applied to the indoor unit up and down. , Even if the mounting plate vibrates, the indoor unit is firmly supported by the mounting plate.

Further, according to the present invention, when the mounting plate is screwed to the wall surface through the hole, the vertically elongated hole is necessarily lowered as compared with the perfect circle or horizontally elongated hole. That way, even if you attach the indoor unit to the mounting plate,
This vertical unit always has a vertical hole.
Therefore, the indoor unit is fixed so that the predetermined direction does not rise.
