  • Patent number: 6338382
    Abstract: In an air conditioner equipped with an air cleaner, a front panel is provided with three air inlets: a first air inlet located on the front face of the front panel, a second air inlet located on the top face thereof, and a third air inlet located therebetween. Each of the first and second air inlets has an opening/closing unit including louvers, and an air cleaner is arranged on the inside of the third air inlet. At the time of cooling/heating operation and at the time of dehumidifying operation, the first and second air inlets are opened and closed by the opening/closing unit, by which the amount of air passing through the air cleaner is changed, thereby utilizing the air cleaner effectively.
