2. Description of the Related Art A conventional wall-mounted air conditioner has been proposed in which a suction opening provided in the front of a housing is provided with a panel which conceals the suction opening when operation is stopped and which is opened during operation. ing. This panel has a structure that can be opened and closed or retractable with the lower part as a fulcrum, or a structure that is slidable in the front-rear direction, so that when the operation is stopped, the suction opening is closed to prevent intrusion of dust and the like. At the same time, the suction opening is formed in a flat plate shape to enhance the design and improve the performance during operation. In addition, in these air conditioners, it is general that a filter is attached and detached from a blowing section.

The prior art is disclosed in, for example, Japanese Patent Application Laid-Open No. 1-244.

It is described in published gazettes such as No. 0 and registered design gazettes.

[0004]

However, in the above-mentioned prior art, 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 high-level work such as wiping the front surface of the housing attached to the wall with a rag or the like is required, there is a problem not only in the 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 sucked in.

Further, in the conventional example, it is difficult to attach / detach a filter that needs frequent cleaning, since the attachment / detachment must be performed through a narrow gap between the blow-out portions. In particular, in an air conditioner that has become a mainstream in recent years and employs a heat exchanger whose cross-sectional shape is bent in multiple stages so as to enclose a once-through fan, in order to cover the heat exchanger, wrap the filter with the heat exchanger. It is necessary to make this curved filter be attached and detached from the narrow gap of the blowout part in terms of ease of use, structure, and from the viewpoint of scattering of dust from the filter when attaching and detaching. There are issues.

Further, in the conventional example described in the Design Gazette, the specific structure for implementing the example is unknown.

An object of the present invention is to provide a control method of a wall-mounted air conditioner that can perform a good operation while improving designability.
