However, in the above-mentioned conventional example, since the panel for concealing or opening the suction opening is directly attached to the front surface of the housing, when removing dust adhering to the panel, Since the work at a high place such as wiping the front surface of the housing attached to the wall surface with a dust cloth or the like is forced, there is a problem not only in cleaning workability but also in safety.
In particular, it is difficult to clean the inside of the panel that forms the passage for the air to be drawn in.

Further, in the conventional example, it is difficult to attach / detach the filter because it is necessary to attach / detach the filter, which needs frequent cleaning, through the narrow gap between the blowing portions. In particular, in an air conditioner that employs a heat exchanger that has become a mainstream in recent years and has a cross-sectional shape that folds in multiple stages so as to wrap the once-through fan, wrap the heat exchanger with a filter to cover the heat exchanger. It is necessary to attach and detach this curved filter from the narrow gap of the blowing part for convenience and structure, or from the viewpoint of dust scattering from the filter when attaching and detaching. There are challenges.

Further, in the conventional example described in the design gazette, the specific structure for carrying out is unknown.

It is an object of the present invention to provide a wall-mounted air conditioner which enhances the design and facilitates the cleaning of the suction part and the attachment / detachment of the filter.
