Next, the operation of the indoor unit 1 according to this embodiment will be described with reference to FIGS.

First, the indoor unit 1 includes a control board in an electric component box (not shown), and a microcomputer provided on the control board includes a fan motor and a louver drive mechanism 2.
The operation of the wind direction plates 11a and 11b, various sensors, and the like is received by the light receiving unit 29 from the remote control by the operation signal from the remote controller, and the entire indoor unit 1 is controlled.

The indoor unit 1 is in a stopped state,
As shown in, the suction Le over bar 17 and the wind direction plates 11a, 1
1b is in a closed first state. In this state, when the signal driving operation from the remote control is performed, a microcomputer, not shown, if the operation signal or automatic operation from the remote controller is set on the basis of various sensor or these information heating and cooling or heating, etc., determining the operation mode, the suction Le over bar 17 and the wind direction plate 11a on the basis of the determined, by operating the 11b, suction Le over bar 17 and the wind direction plates 11a, 11b
Is operated so as to take the second state where is opened.

That is, the microcomputer operates a drive motor (not shown) to open the wind direction plates 11a and 11b to a blowing angle corresponding to the operation mode. Further, the microcomputer operates the drive motor 201 which opens the suction louver 17 in conjunction with the operation of the wind direction plates 11a and 11b. The rotation torque of the drive motor 201 is transmitted to gears 203 arranged on both sides via a connecting rod 209 having a gear 211,
By rotating the pair of gears 203 by the same rotation, the rack 207 is moved up and down along the rack support 219 via the plate gear 205. The movement of the rack 207 is determined by the engagement between the engagement portion 213 and the projection 302,
1 is moved up and down, the interlocking shafts 307 of the plurality of suction louvers 17 are moved along the sliding holes 309, and the suction louvers 17 are opened with the rotation shaft 19 as a fulcrum to open to the second state.

Next, the microcomputer rotates the once-through fan 45 to draw indoor air from the first, second, and third suction portions 13, 23, and 25, and does not exchange hot air, cold air, or heat with the heat exchanger 47. Is controlled so as to blow out from the blowing section 9 along the wind direction plates 11a and 11b. On the other hand, when stopping the operation, after stopping the once-through fan, the drive motor 2
By controlling the drive motors of the wind direction plates 03 and the wind direction plates 11a and 11b to rotate in reverse, control is performed so as to return from the second state to the first state.

As described above, according to the indoor unit 1 of the present embodiment, in the first state in which the operation is stopped, the first suction portion 13 and the blowout portion 9 whose interiors are exposed in the installed state are sucked. Since the indoor unit 1 can be concealed through the louver 17 and the wind direction plates 11a and 11b with a plane substantially flush with the housing surface of the indoor unit 1, the indoor unit 1 is adapted to the wall mainly composed of a flat surface and harmonized with the interior of the room. Further, it is possible to reduce the entry of dust and the like from the first suction part 13 and the blowing part 9.

On the other hand, in the second state of the operating state, in addition to the second and third suction portions 23 and 25 which are always open, the suction louver 17 of the first suction portion 13 is opened to open the opening ratio. , The room air can be sucked in from a wide area, so that the airflow resistance can be reduced and the cooling / heating capacity and noise can be reduced. In particular, since the suction louver 17 is divided into a plurality of upper and lower parts, the amount by which the suction louver 17 projects forward when the suction louver 17 is opened can be reduced. Further, since the suction louver 17 is opened obliquely by opening the upper part of the suction louver 17, it is possible to make the inside of the first suction portion 13 difficult to see even when looking up from below in the installed state. In addition, the short circuit in which the blown air is immediately sucked into the first suction portion 13 can be reduced. In addition, in this embodiment, since the rotating shaft 19 is provided at the center of the side end of the suction louver 17 so that the lower portion of the suction louver 17 enters the inside when opened, the rotation shaft 19 moves forward when opened. Of the suction louver 17 can be further reduced, and the feeling of pressure caused by the suction louver 17 and the like protruding largely forward when the wall is installed can be reduced.

In this embodiment, the wind direction plates 11a, 1
