Abstract

An indoor unit (2) for an air conditioner (1) has a casing (23), a plate-like section (26), and a heat insulating material (27).The casing (23) has indoor air inlets (52a, 53a) and outlet (56a). The plate-like section (26) and the heat insulating material (27) define a gap (S1) that is near the outlet (56a) and into which the indoor air enters. Airflow resistance increasing regions (C1, C2) are formed in the plate-like section (26) and the heat insulating material (27). The Airflow resistance increasing regions (C1, C2) are shaped to increase airflow resistance in the gap (S1). In the indoor unit (2) of the air conditioner (1), growth of condensation water near the outlet (56b) is suppressed, and this in turn suppresses dropping of the water.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner. Background technique [0002] In an indoor unit of an air conditioner, a gap may be defined by various members present in the vicinity of the air outlet in the vicinity of the air outlet formed in the casing of the indoor unit. In such a case, during the operation of the indoor unit, indoor air containing moisture may enter the gap and the moisture contained in the indoor air may be trapped in the gap Condensation increases and drips to the outside of the case. Especially when the indoor unit is performing cooling operation, since the temperature of the air blown into the room through the air outlet is low, the indoor air entering the gap near the air outlet is cooled by such cold air, and the dew condensation water tends to increase. In addition, especially when the indoor unit is performing a cooling operation or a dehumidification operation, the indoor air that has entered into...
