AIR-CONDITIONING INDOOR UNIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/054180
Kind Code:
A1
Abstract:
An air-conditioning indoor unit (1) is provided with a control device (100). In the case of performing an operation in a first airflow control mode in which a downstream gap is set wider than an upstream gap for the flow of blowing air between a first horizontal vane (41) and a second horizontal vane (51) to cause a portion of the blowing air to flow along a lower airfoil surface of the first horizontal vane (41) and cause another portion of the blowing air to flow along an upper airfoil surface of the second horizontal vane (51), the control device (100) performs an operation in a second airflow control mode in which a clearance angle between the first horizontal vane (41) and the second horizontal vane (51) is set narrower than a predetermined clearance angle between the first horizontal vane (41) and the second horizontal vane (51) in the first airflow control mode to blow out the blowing air, and then transitions to the operation in the first airflow control mode following the operation in the second airflow control mode.
