- the opening degree of the front panel 6 can be adjusted only by pulse-controlling one panel drive motor 73 that does not require a complicated mechanism.
- the air conditioner indoor unit 1 has the highest aesthetics that have the highest intelligence in the closed state. And, as the opening degree of the first suction port 21 is larger, the outer shape of the indoor unit 1 of the air conditioner changes and the interior property is deteriorated. For this reason, the first open state, which is the least beautiful in the second open state, has a higher aesthetic than the second open state.
- the state of the front panel 6 can also be selected as the closed state, the first open state, and the second open state force. Therefore, residents and the like can select the outer shape of the indoor unit 1 of the air conditioner from the viewpoint of aesthetics by selecting the operation mode.
- the control unit 8 controls the fan motor 4. Accordingly, the output of the blower fan 3 may be set to the first air volume and the panel drive motor 73 may be controlled to open the first suction port 21 at the second opening. In this control, the air volume from the blower fan 3 is the same as the first air volume in the normal cooling / heating operation, but the first suction port 21 is opened wider, so that the wind noise of the intake air is reduced and the operation sound is reduced. Reduced.
- the length of the lower end of the front panel 6 is shortened for smooth opening and closing operation, and the vicinity of the lower end of the horizontal flap 5 is not covered by the front panel 6.
- the front panel 6 covers the entire horizontal flap 5.
- the front panel 6 in the closed state should be as wide as possible and cover the range of the first inlet 21 and the outlet 20 from the aesthetic point of view! It is not limited to the one that completely covers all of the outlets 20, and may be one that covers at least a part of the first inlet 21 and the outlet 20.
- the front panel 6 in the closed state is not necessarily limited to the state in which the first air outlet 20 is closed, but is not completely sealed, and does not exclude the case where the front panel 6 is opened at a slight opening.
- the second opening is the maximum opening of the first suction port 21, but the first suction port 21 can be opened with a larger opening than the second opening is not at the maximum opening. You may do it.
- the first suction port 21 may be opened larger than the second opening degree in other operation modes, filter maintenance, or when the front panel 6 is removed.
- the front panel 6 may be provided with some play so that it can be manually opened larger than the second opening.
- the operation mode selected from the viewpoint of the aesthetics of the indoor unit 1 of the air conditioner that may be instructed by the remote controller 9 is different from the operation mode in the above embodiment. May be.
- the night operation mode selected when the occupant is sleeping and does not care about the appearance of the indoor unit 1, or when the resident is absent in the room and the appearance of the indoor unit 1 is not concerned It may be possible to select an unattended operation mode in which ventilation is performed.
- the front panel 6 is in the second open state. Since this is the operation mode that is selected when the resident or the like does not care about the appearance of the indoor unit 1, open the first suction port 21 to reduce the rotational speed of the fan motor 4 and the frequency of the compressor. Power consumption can be reduced.
- the front panel 6 changes from the closed state to the two open states of the first open state and the second open state, but the front panel 6 may change to three or more open states.
- the inlet 21 may be opened in three or more stages. That is, the control unit 8 is not limited to the two stages of the above-described embodiment as long as the opening degree of the first suction port 21 can be changed to a desired opening degree in a plurality of stages.
- the first suction port 21 is opened at the same second opening degree during the full operation and the sleep operation, but may be opened at different opening degrees.
- the force at which the first suction port 21 is opened at the same opening degree in the same operation mode, and the opening degree of the first suction port 21 may be adjusted in the same operation mode. . This allows finer adjustment of the opening according to the driving situation.
- the front panel 6 moves in two modes of parallel movement and rotational movement, but the mode of movement is not limited to these. Further, when the front panel 6 is moved to the first open state, the front panel 6 does not have to be strictly linear, and may have a slightly curved curve. Further, when the front panel 6 shifts to the first open state force and the second open state, the trajectory of the front panel 6 does not have to be strictly an arc shape, and may be a curved shape instead of an arc shape. .
