Patent ID: 10895388

Abstract:
An indoor unit for an air-conditioning apparatus, which prevents adhesion of dew condensation water to up-and-down airflow direction louvers while directing blowing air to an intended direction, includes: a casing; an air inlet; an air outlet; an indoor heat exchanger and an indoor fan; an up-and-down airflow direction louver; and an up-and-down airflow direction auxiliary louver. The up-and-down airflow direction louver includes: an upstream guide surface and a downstream guide surface. The up-and-down airflow direction auxiliary louver includes an upstream end portion, the upstream end portion being positioned on an inner side of the air outlet passage relative to the downstream guide surface and being positioned on the upstream side relative to a downstream guide surface distal end portion of the downstream guide surface, which is an end portion of the downstream guide surface on the downstream side of the air outlet passage.
