Problems solved by technology

[0006] However, since it is a hollow structure, due to the volume change of the internal air due to temperature changes, cold air may be sucked into the internal space, which causes a decrease in thermal insulation performance.
In addition, when the hollow structure is made into a completely sealed state to prevent this phenomenon, there will be a problem that the wind direction adjustment blade itself expands and contracts and deforms.

Abstract

It is intended in an air-conditioning indoor unit to enhance airtightness of a hollow structure of an airflow direction adjustment louver and prevent expansion and shrinkage of the airflow direction adjustment louver itself. In the air-conditioning indoor unit (10), air movement is enabled between inside and outside of the airflow direction adjustment louver (31) only through a vent hole (312). Moreover, the vent hole (312) does not exist in a pathway of blown air. Hence, it is avoided that cold air blown out in a cooling operation intrudes into the airflow direction adjustment louver through the vent hole.

Description

technical field [0001] The invention relates to an air-conditioning indoor unit, in particular to an air-conditioning indoor unit provided with wind direction adjusting blades near the air outlet. Background technique [0002] The entire airflow direction adjustment vane provided near the air outlet of the air conditioner indoor unit is cooled by cold air. Therefore, when the surface temperature of the airflow direction adjusting blade is lower than the dew point, dew condensation occurs on the surface where the cold wind does not reach. [0003] In the past, thermal insulation components were pasted on the specified parts of the wind direction adjustment blades to prevent this kind of condensation. In recent years, in order to avoid the decline in the aesthetic effect caused by the pasting of thermal insulation components, for example, through patent document 1 (Japanese Patent Application Laid-Open No. 2009-14289 No. 1999-2000 Publication, the airflow direction adjustment...
