GAS FIRED HOT-AIR HEATER EQUIPPED WITH AIR CLEANER

摘要

PROBLEM TO BE SOLVED: To increase a dust collecting rate as well as a smell removing rate and unify a temperature in a room upon heating operation. SOLUTION: An air cleaning fan 15 and an air cleaning filter 13 are provided on the upper part of a hot-air heating unit so as to constitute them perfectly separated from a hot-air outlet passage. On the other hand, a convection air cleaning filter, having a fine mesh and a large area for removing dust as well as smell sufficiently, is mounted to increase a dust collecting efficiency and a smell removing rate while the air cleaning fan 15 is operated upon heating operation to mix high-temperature air near a ceiling and unify a room temperature.
