PURPOSE:To clean air and to generate hot air with one blower by branching the part of the air passage on the downstream side of the blower into an air passage having a heating means and an air passage communicating directly with a discharge port. CONSTITUTION:One blower 19 is set in an air passage C, and filters 21-23 for cleaning air are provided on the upstream side of the blower 19 in the passage C. Furthermore, the part of the passage C on the downstream side of the blower 19 is branched into the air passage 6 having a heating means 27 and the air passage 6' communicating directly with the discharge port 10a. As a result, air is cleaned and hot air is generated with the one blower, low noise is realized, and the cost is reduced since the number of parts is decreased. |
