Title: INDOOR UNIT AND AIR-CONDITIONING DEVICE
Abstract:
The purpose of the present invention is to divide the downstream side of a heat exchanger in an indoor unit of an air-conditioning device when viewed in a vertical cross section with regard to the rotational axis of a centrifugal fan, into a first region between the heat exchanger and a blowing port, and a second region encompassing the remaining area, deflecting the airflow in the vicinity of a louvre generated by the airflow that flows into the blowing port after passing through the second region, and thereby improving the performance of the air-conditioning device. In order to achieve this purpose, this indoor unit comprises a housing, a motor that generates rotational driving force, a centrifugal fan which is mounted to the motor and which blows out air sucked in from beneath, in a circumferential direction, a heat exchanger that surrounds the blowing direction of the centrifugal fan, and a blowing port that blows out air that has passed through the heat exchanger. Defining the part of the downstream part of the heat exchanger which is between the heat exchanger and the blowing port as a first region and the remaining area as a second region, a partition member which at least partially blocks the airflow which flows from the second region to the blowing port is provided.
