摘要

An air conditioner has an indoor unit, which includes an indoor unit housing accommodating therein a heat exchanger and a circulating fan for blowing air heat exchanged by the heat exchanger into a house room. An air filter, the heat exchanger and the circulating fan are accommodated within an air flow passage fluid connecting between air intake perforations and an air blow-off opening, both defined in the indoor unit housing. A dust collecting unit is disposed in the indoor unit housing for collecting dust particles removed from the air filter. The air filter is divided into a plurality of filter members in a direction conforming to a direction of movement thereof, each of which is reciprocatingly passed across the dust collecting unit.
