The air is blown out from the air outlet (9b) into the indoor space to perform air conditioning of the indoor space.

The operation of the present embodiment is as follows.
This is the operation when the conditioned air is blown from the air outlet (9b) into the indoor space. This blowing operation is performed in accordance with a blowing mode previously selected by a remote control operation. In other words, when the horizontal blade (13) is driven in a fixed state, when the draft prevention mode is selected, five stages of the rotation range (PO to P4) shown in FIG. The horizontal blades (13) in five stages of the rotation range (PO 'to P4') shown in FIG. 4 and five stages of the rotation range (PO "to P4") shown in FIG. 5 when the ceiling dirt prevention mode is selected. ) Can be set to a fixed angle. On the other hand, when the horizontal blade (13) is driven in a swing state, the rotation range (PO to P4) shown in FIG. 3 when the draft prevention mode is selected, and the rotation range shown in FIG. 4 when the standard mode is selected. The rotation range (PO 'to P4') and the rotation range (PO "to P4" shown in FIG.
4 ″), a swing operation is performed.

In particular, when the ceiling dirt prevention mode is selected, the conditioned air blown out from the air outlet (9b) does not come into contact with the ceiling surface (R). The ceiling surface (R) is not contaminated by the particulate dust contained in the ceiling.

As described above, according to the present embodiment, it is not necessary to attach or detach the auxiliary fin for changing the blowing direction of the conditioned air at the time of installation of the air conditioner as in the related art. It is not necessary to set the position of the horizontal blade so that the conditioned air does not contact the ceiling surface. However, if there is a need to keep the ceiling surface (R) clean, the horizontal blade (13) can be rotated. By restricting the range, generation of dirt on the ceiling surface (R) can be reliably and easily avoided.

In this embodiment, three modes can be selected as the blowing mode. However, the present invention is not limited to this mode. Two blowing modes including a ceiling dirt prevention mode and four or more blowing modes are provided. The information may be stored in the mode storage means (16) and selected by operating the remote controller.

If there is no need to perform operations such as setting to prevent contact, but there is a need to keep the ceiling surface clean, restricting the range of fixing or rotating the horizontal blades ensures that the ceiling surface is not stained. And it can be avoided easily.

Further , since one of the plurality of blowing modes is a horizontal blowing allowable mode in which a conditioned air blowing range is set so as to allow the blowing of the conditioned air along the ceiling surface, it is possible to prevent the ceiling surface from being stained. Also, when there is a demand to prioritize indoor air conditioning, by selecting this horizontal blow permission mode, it is possible to blow out conditioned air over a wide range, and the air conditioning performance accompanying the uniformization of the indoor temperature is improved. Improvement can be achieved.

Further , since the mode selection means is provided in the remote controller for operating the operating condition of the air conditioner, a desired blowing mode can be selected by a simple operation such as operation of the remote controller.
