Indoor unit of air conditioning apparatus

摘要

An indoor unit of an air conditioning apparatus includes a casing, a heat exchanger, a fan, a first airflow direction adjusting plate adjusting a direction of airflow blown out from an air outlet by rotation about a first axial direction, a plurality of second airflow direction adjusting plates adjusting the direction of the airflow blown out from the air outlet by rotation about a second direction substantially perpendicular to the first direction, and a support member rotatably supporting the first airflow direction adjusting plate in the air outlet other than at both end portions. The second airflow direction adjusting plates include a third airflow direction adjusting plate and a fourth airflow direction adjusting plate placed in a location such that a distance to the support member from the fourth airflow direction adjusting plate is smaller than a distance to the support member from the third airflow direction adjusting plate.

主权项

1. An indoor unit of an air conditioning apparatus, the indoor unit comprising:
a casing having an air inlet and an air outlet; a heat exchanger placed inside the casing; a fan arranged to generate an airflow leading from the air inlet to the air outlet; a first airflow direction adjusting plate arranged and configured to adjust a direction of the airflow blown out from the air outlet by rotation about a first direction corresponding to an axial direction of the first airflow direction adjusting plate; a plurality of second airflow direction adjusting plates arranged and configured to adjust the direction of the airflow blown out from the air outlet by rotation about a second direction that is substantially perpendicular with respect to the first direction; and at least one support member rotatably supporting the first airflow direction adjusting plate with respect to the casing at least in a portion of the air outlet other than both end portions along the first direction, the plurality of the second airflow direction adjusting plates including at least one third airflow direction adjusting plate adjacent to the support member on one side and at least one fourth airflow direction adjusting plate adjacent to the opposite side of the support member placed in a location such that a distance to the support member from the fourth airflow direction adjusting plate is smaller than a distance to the support member from the third airflow direction adjusting plate, and a size of the fourth airflow direction adjusting plate being smaller than a size of the third airflow direction adjusting plate in a vertical direction substantially perpendicular to the direction of the airflow, in order to prevent condensation from forming on the fourth airflow direction adjusting plate and the support member.
