Abstract
The indoor unit includes a plurality of outlet openings. In airflow rotation of the indoor unit, a full blowout mode and a partial blowout mode are executed. In the full blowout mode, all the outlet openings blow conditioned air. In the partial blowout mode, the flow of the blowing air of part of the outlet openings are blocked by the air current blocking mechanism, and thus the blowing wind speeds of the remaining outlet openings increases. As a result, an air temperature difference among parts of the indoor space decreases, and the comfort of the indoor space is improved.

An indoor unit of an air conditioner installed on a ceiling and blowing conditioned air into an indoor space, the indoor unit comprising:
- a plurality of outlet openings each provided with an air current blocking mechanism blocking a flow of the conditioned air;
- and
- a controller controlling the air current blocking mechanism to execute airflow rotation while repeatedly switching an operation between
- a full blowout mode of suppling the conditioned air from all the outlet openings to the indoor space and
- a partial blowout mode of blocking flow of blowing air of part of the outlet openings by the air current blocking mechanism and increasing a blowing wind speed at the part of outlet openings,
- wherein
- each of the plurality of outlet openings is provided with a wind direction adjusting slat for shifting a direction of blown air upward and downward;
- and the controller controls the wind direction adjusting slat so that
- in a heating operation in which heated conditioned air is supplied to the indoor space,
- during the full blowout mode, the flow of the blowing air of all the outlet openings is directed downward, and
- during the partial blowout mode, the flow of the blowing air of the outlet openings at which the blowing wind speed increases is directed horizontally.

- each of the plurality of outlet openings is provided with a wind direction adjusting slat for shifting a direction of blown air upward and downward;
- and
- the controller controls the wind direction adjusting slat so that
- in a cooling operation in which cooled conditioned air is supplied to the indoor space,
- during the full blowout mode, a direction of the flow of the blowing air of all the outlet openings varies and
- during the partial blowout mode, the flow of the blowing air of the outlet openings at which the blowing wind speed increases is directed horizontally.
