- the angular position of the louver 7 is automatically set from the provided control device. For example, when the first angle is 28 degrees, the third angle is larger than 0 degrees, which is a fully closed angle when the indoor unit is stopped, and the first angle which is the minimum angle that the user can set from the remote control It is set to an angle smaller than 28 degrees, for example, 14 degrees.

- the louvers 7 of some of the outlets 5 are set at the position of the third angle (the angle larger than the fully closed angle of the louvers but smaller than the first angle), as shown by hatching circles in FIG.
- a small gap 21 can be formed between the wall surface of the outlet 5 and the end of the louver 7. Therefore, since the air flow can be blown out from the gap 21, the deflection of the louver due to the wind pressure can be reduced. Therefore, since the deflection of the louver 7 can be suppressed to a small value, plastic deformation of the louver can be suppressed even when high temperature air is blown out into the room.
- the louvers 7 set to the third angle may be configured to be sequentially switched at predetermined time intervals.
- the louvers 7 of the other outlets 5 are louver operations that can be set from the remote control. That is, the other louvers 7 are set to the automatic swing or set to an arbitrary louver angle.
- the predetermined predetermined operating condition of the air conditioner is, for example, the following operating condition, and when the following operation is performed, a part of the outlets of the louvers of the plurality of outlets.

- a predetermined temperature difference which is predetermined, during heating operation or cooling operation.
- the high-speed blowout setting is made to allow the blowout air to reach far from the normal such as near the floor surface.
- the stirring operation is set to increase the blowing air velocity and reduce the temperature difference between the upper and lower portions of the room during heating operation or the control device of the air conditioner automatically executes the stirring operation If.
- the third angle is not allowing the user to set an arbitrary louver to the third angle from the remote control, and the air conditioning is performed when the high-speed blowout setting or the like is performed.
- This is an angle that is automatically set from the machine control unit. For example, when one of the operations (1), (3), and (4) described above is set, or when the operation is performed under the conditions of the above (2), the stirring operation of the above (4) is automatically executed. In this case, the angle of the louver 7 of any of the outlets 5 is automatically set to the third angular position from the control device.
- the opening area of the blowout port 5 of the louver portion set at the third angle is reduced, so the volume of air blown out from the blowout port 5 is significantly reduced. It is possible to sufficiently increase the wind speed from the air. Therefore, the blown air can reach a sufficiently distant position such as a floor surface.
- the small gap 21 described above can be formed between the wall surface of the blowout port 5 and the end of the louver 7. Since the air flow can be blown out from the above, the deflection of the louver 7 due to the wind pressure can be reduced. Therefore, even if a large amount of high temperature air is blown into the room by increasing the rotational speed of the centrifugal fan 9, the deflection of the louver 7 can be reduced, and therefore the plastic deformation of the louver 7 can be suppressed.
- the angle of the louver of a part of the plurality of the outlets is set to the third angle when a predetermined operation condition is reached.
- it may be configured as follows. That is, when the predetermined operation condition is reached, the angle of the louver 7 of a part of the plurality of air outlets 5 is not immediately controlled to the third angle, and the louver 7 is plastic first Alternatively, the louver 7 may be first controlled to the third angle after the predetermined time has elapsed after the predetermined closing time is maintained for a predetermined time that does not cause deformation.
- the minimum angle which can be set by the remote control is the first angle
- the louver angle which is larger than the fully closed angle which is the louver angle when the indoor unit is stopped and smaller than the first angle may be configured as follows. That is, if the louver has the function of causing the automatic swing, the minimum angle of the louver at the time of the automatic swing is taken as the first angle, which is larger than the fully closed angle which is the louver angle at the time of stopping the indoor unit and smaller than the first angle.
- the louver angle may be set to the third angle. In this case, the louvers of the other outlets 5 provided with louvers other than the louvers set to the third angle are set to an automatic swing or an arbitrary angle.
- the angle of the louver 7 of a part of the plurality of the blowout ports 5 under a predetermined operation condition set in advance for example, when the high speed blowout setting is made Is set to a third angle which is larger than the fully closed angle (0 degree) which is the louver angle when the indoor unit is stopped and which can be set by the remote control or smaller than the first angle which is the minimum angle when Since the louvers 7 of the air outlet are configured to perform louver operation that can be set from the remote controller, they are provided at each air outlet 5 while enabling high-speed air outlet from some air outlets of the plurality of air outlets 5 There is an effect that it is possible to obtain the indoor unit of the air conditioner that can also suppress the deflection of the louver 7 that is being performed.
