１３の交換を行わなくてもよい。In the above configuration, the operation is performed in two stages of a dust collection mode and a regeneration mode. First, in the dust collection mode, by driving the air blowing means 16, dust and air containing fine particles such as molds, mites, pollen, viruses, bacteria, etc. outside the main body 10 are discharged from the hollow portion of the dust collection means 12 to the outer periphery. Flows in the radial direction toward the part,
It is filtered on the inner surface of the hollow part. At this time, since the heating means 17 is not driven, there is no rise in room temperature. When the dust collection mode is operated for a certain period of time, fine particles are collected on the inner surface of the filter 13 of the dust collection means 12. Therefore, the reproduction mode is entered next. In the regeneration mode, after stopping the blowing means 16 or reducing the blowing amount, the heating means 17 is driven to heat the inner surface of the hollow portion of the dust collecting means 12 by convection and radiation. FIG. 3 shows the residual ratio after pyrolysis at each temperature of pollen measured by a thermobalance.
As can be seen from FIG. 3, when the temperature reaches 500 ° C., the residual ratio becomes almost zero. Note that other fine particles such as house dust also show the same tendency. Accordingly, in the regeneration mode, the fine particles collected on the inner surface of the filter 13 are thermally decomposed by setting the inner surface of the hollow portion to 500 ° C. or higher and 1300 ° C. or lower which is the heat-resistant temperature of the ceramic filter 13 such as alumina-silica. Since the clogging does not occur, the filter 13 need not be replaced.

熱手段１７をフィルタ１３が取り囲んでいる構成ため内

の構成よりも再生モードで省エネルギーが実現できる。The filter 13 such as a ceramic fiber has a low thermal conductivity of about 0.05 W / m · K, and the temperature of the inner surface is kept higher than that of the outer surface because the filter 13 surrounds the heating means 17. Energy can be saved in the regeneration mode as compared with the configuration of the flat filter.
【００１９】なお、集塵手段１２のフィルタ１３は、平

The fine particles flow radially from the hollow portion of the dust means 18 toward the outer peripheral portion, and the fine particles are filtered on the inner surface of the hollow portion of the dust collecting means 18.

きる。In the meantime, the filter 19 of the present invention meandering with irregularities can have a larger filtration area with the same outer dimensions as the filter of the first embodiment.
For example, in the case of a filter having 20 steps of irregularities having a height of 25 mm so as to have an outer dimension of 120 mm in diameter, the filtration area can be increased by about 2.7 times as compared with the cylindrical filter having an outer diameter of 120 mm in Example 1. Therefore, pressure loss in the filter can be reduced, and downsizing and low noise of the blowing means can be realized.
