  • Patent number: 6164082
    Abstract: An air conditioner equipped with an air cleaner. In the air conditioner, a dust collector is arranged in an air path located behind a heat exchanger. A dust collecting electrode of the dust collector is combined with a heater for self-cleaning. An opening, which communicates the air path located behind the heat exchanger with the outside, is provided above the dust collector. An open-and-close valve, which is closed during the air conditioning operation and opened in the case where the air cleaning operation is carried out while the air conditioning operation is stopped, is provided at the opening. The dust collector does not interrupt the flow of air during the air conditioning operation and also in the case where the air cleaning operation is carried out while the air conditioning operation is stopped.

  • Patent number: 6136074
    Abstract: An air conditioning apparatus with an air cleaning function. In the apparatus, an electric dust collector is provided in the air passage on the rear side of a heat exchanger. A heater for self-cleaning is combined with a dust collector electrode of the electric dust collector. A heat shield plate is combined with the heater. Air flow resistance is not increased although the dust collector electrode is plane in shape. An increase of air flow resistance caused by the use of the heat shield plate is also suppressed.
