And a lower surface outlet 5 composed of a fan casing 2 and a lower surface outlet 5 composed of an auxiliary fan casing 4 are provided side by side so as to communicate with the suction port 1.

A heat exchanger 6 bent in an inverted V-shape is provided in an air passage connecting the suction port 1 to the front air outlet 3 and the lower surface air outlet 5, and the fan casing 2 is provided. A through-flow fan 8 linked to a fan motor 7 is housed therein, and an auxiliary through-flow fan 9 coaxially connected to the through-flow fan 8 is housed within the auxiliary fan casing 4. .

The main body A having the above-mentioned structure is installed on a wall surface B having a window portion C in an air-conditioned room, and suction air sucked from the suction port 1 by the once-through fan 8 is heat-exchanged. The heat is exchanged in the vessel 6 and is blown from the front air outlet 3 to the air-conditioned room as indicated by the arrow D, and the wall surface B and / or the window C is emitted from the lower surface outlet 5 as indicated by the arrow E. The air is blown out to the air-conditioned room so that the air-conditioning of the air-conditioned room can be effectively performed.

That is, for example, during the heating operation, warm air is blown out from the lower surface outlet 5 as shown by an arrow E, so that the cool air near the wall surface B and / or the window portion C is effectively diffused. And at the same time,
Warm air is blown out from the front air outlet 3 as indicated by an arrow D, so that it is not necessary to feel cold in various places in the air-conditioned room.

Next, the auxiliary fan casing 4 and the auxiliary flow-through type fan 9 are connected to the main body A as an example.

As a result, the wind direction deflector 10 can be smoothly rotated, and the warm air blown out from the lower surface outlet 5 during the heating operation is smoothly deflected to the left and right by the wind direction deflector 10. Further, since the height 10b 'of one side surface is formed to be lower than the height 10b''of the other side surface, the lower surface is formed as indicated by an arrow E shown in FIGS. 1 and 3. The warm air blown out from the outlet 5 can be effectively deflected.

As in the other embodiment described above with reference to FIG. 4, when the lower surface outlet 5 and the wind direction deflector 10 are provided at the lower portions on both sides of the main body A, the heating operation is performed. The warm air at that time can be deflected and blown out so as to spread from the lower portions on both sides as indicated by arrow E.

Alternatively, although not shown, the wind direction deflector
When 10 is attached to the lower surface outlets 5 at the lower portions on both sides of the main body A with both side surfaces 10b thereof being horizontally inverted, the warm air during heating operation is deflected in the horizontally inverted direction and blown out. It becomes possible.

Further, the wind direction deflecting body 10 is provided with an opening / closing body 11 for adjusting the amount of ventilation by opening the wind direction deflecting body 10 in a fully open state or a half open state, for example.

The opening / closing body 11 includes front and rear support plates in which a support hole 11a provided at a base end is rotatably supported by a support shaft 10c projecting inside the front and rear surfaces of the wind direction deflecting body 10. 11b
