- the control unit 30 causes the air blowing guide path to be longer than the depth length of the horizontal louver alone by the cooperation of the upper surface (inner surface 18b) of the horizontal louver 18 and the upper surface 19a of the rectifying plate 19 in the upper blowing posture A of the horizontal louver 18.
- the rotational posture (upper blowing posture) of the lateral louver 18 is controlled so as to form
- control unit 30 can control the rotational speed of the fan motor 33 by a command signal from the operation unit 31 or a temperature signal from a temperature sensor (not shown) to control the air volume of the fan 7.
- control unit 30 also controls the rotational speed of the fan motor 33 depending on the rotational state of the lateral louver 18. That is, when the lateral louver 18 is switched from the lower blowing posture C or the upper blowing posture A to the closed posture B, the fan motor 33 is controlled to be slow or stopped. In the closed posture B of the horizontal louver 18, as shown in FIG. 2, the opening of the cabinet 1 is almost closed, so that when the fan motor 33 is operated normally in this state, the load applied to the fan 7 becomes lighter. Then, since the rotation speed of the fan 7 increases, it may cause abnormal noise. Therefore, the control unit 30 controls the fan 7 to stop when the lateral louver 18 shifts to the closed posture B.
- the control unit 30 receives a signal from the louver position detection unit 32, and controls the fan 7 to stop or switch to low speed operation as the horizontal louver 18 approaches the closed posture B.

Further, when the lateral louver 18 is switched from the closed posture to the upper blowing posture A or the lower blowing posture C, the control unit 30 controls to gradually increase the rotational speed of the fan motor 33 and drive it at the original rotational speed.
- control unit 30 also controls the rotational speed of the lateral louver motor 24 so that the lateral louver 18 is rotated at different rotational speeds when switching from the upper blowing posture A to the closed posture B and when switching from the lower blowing posture C to the closed posture B.
- the rotation speed is controlled.
- the rotational angle from the upper blowing posture A to the closed posture B of the horizontal louver 18 is smaller than the rotational angle from the lower blowing posture C to the closed posture B. That is, since the opening 3 of the cabinet 1 is formed obliquely downward in the lower front portion of the cabinet, the closed posture B of the lateral louver 18 is in a state where the lower end 18c is inclined to the outlet side from the vertical direction. On the other hand, the lower blowing posture C of the horizontal louver 18 is a state in which the lower end 18c is opened forward from the vertical direction. On the other hand, the upper blowing posture A of the horizontal louver 18 is a state in which the lower end 18 c is close to the current plate 19.
- the rotation angle from the closed posture B to the upper blowing posture A of the lateral louver 18 is smaller than the rotation angle to the lower blowing posture C. Therefore, if switching to a posture with a different rotation angle is performed at the same speed, the transition time from the closed posture B to the upper blowing posture A is shorter than the transition time from the closed posture B to the lower blowing posture C. There is a possibility that the rotational speed control (stop control) that slows down the rotation of the fan motor 33 during the transition from the posture A to the closed posture B cannot catch up with the rotational speed of the lateral louver 18.
- the rotational speed of the lateral louver motor 24 is slower in the transition from the upper blowing posture A to the closed posture B of the lateral louver 18 than in the transition from the lower blowing posture C to the closed posture B.
- the fan motor 33 is controlled to be surely stopped or driven at a low speed.

- the rotational speed of the lateral louver motor 24 is controlled to be slowed down, and the rotational speed control for slowing down the rotational speed of the fan motor 33 catches up with the rotational switching operation of the lateral louver 18. .
- the load applied to the fan 7 becomes lighter as it approaches the closed posture B, and it is possible to prevent the generation of abnormal noise caused by the increase in the rotational speed of the fan 7.
- the lateral louver 18 when the indoor unit is stopped, the lateral louver 18 is in the closed posture B in which the front opening 3 of the cabinet 1 is substantially closed as shown in FIG.
- the control unit 30 receives the signal to drive the refrigeration cycle, and the lateral louver 18 is blown upward from the closed posture B.
- the fan motor 33 is driven and controlled.
- the fan 7 rotates and the air is blown forward from the air outlet 4 through the air passage 5.
- the inner surface 18b of the horizontal louver 18 and the upper surface 19a of the rectifying plate 19 are combined in a pseudo manner so that they are substantially continuous.
- the ventilation guide path becomes a ventilation guide path longer than the ventilation guide path of a single horizontal louver in the front-rear direction, it is possible to send the wind far and improve the ventilation performance.
- the combination of the existing lateral louver 18 and the rectifying plate 19 forms a long air guide path in the front-rear direction, so the depth of the lateral louver alone is increased, or another air guide member is added. Compared to the case, it is possible to reduce the number of parts and make the system compact, and to reduce the cost.
- the air blowing guide path discharges the wind blown from the outlet 4 obliquely upward (toward the ceiling) along the concave curved surface. Can send wind up to.
- the control unit 30 receives the signal, drives the refrigeration cycle, and blows down the lateral louver 18 from the closed posture B when predetermined conditions are satisfied.
- the lateral louver motor 24 and the fan motor 33 are driven and controlled to switch to the posture C (see FIG. 4).
