[Problems to be solved by the invention]
However, due to the positional relationship between the air conditioner and the remote control device and the relationship with the wall surface where the remote control device is installed, it is difficult to guide the wiring conveniently into the main body with only one wiring inlet. There is a case. Therefore, it is proposed to provide a plurality of wiring inlets on the upper surface of the main body or the back cover. In such a case, especially when the wiring is not passed through the wiring inlet located on the upper surface side of the main body, if the wiring inlet is left open, dust or the like enters the main body through the wiring inlet. However, problems such as adhesion failure on the wiring board and the like occur.
[0006]
In addition, remote control devices that have been used in the past employ an installation method in which they are fixed by embedding them in a hole in the wall surface so that they can be placed in a box with a hole in the wall surface defined by JIS (Japanese Industrial Standard). The shape is limited.
[0007]
For this reason, the smaller body that does not fit the installation box in the hole in the wall surface is exposed to the outside of the gap between the hole in the wall surface and the body, so it is virtually impossible to adopt the wall embedding method of the remote control device. There is a problem that is bad.
[0008]
An object of the present invention is to provide a remote control that does not allow dust or the like to enter through a wiring inlet, and that can be easily and nicely installed without exposing a gap to the outside even if the size is smaller than a hole in a wall surface.
