<p>PURPOSE:To prevent an electric appliance part from being tainted by outer air by forming open parts in the lower part of a fan in a partitioning board and the upper part of a contactor and at the same time forming an air circulating route. CONSTITUTION:Air which is taken in through an air intake 1 is led to an electric dust collecting element 4 and the dust is electrically positively charged by an ion shower and collected. Cleaned air after the dust collection is sent out through an air outlet 2 by a fan 5. Passing an open part 12a, a part of the cleaned air is led to an electric appliance storage part 7. While cooling the electric appliance 14, the air moves toward another open part 12b and comes in a contact space 11. Further, the air passes a gap 13a and returned to the fan 5 so that an air circulating route is formed. In this way, the electric appliance part and an insulator are prevented from being tainted by outer air.</p> |
