PROBLEM TO BE SOLVED: To suppress the generation of offensive odor upon start of combustion in a deodorizing method for a fan heater with an air cleaning function for performing deodorization by repeating adsorption and regeneration. SOLUTION: In a fan heater, after combustion exhaust gas is guided to the upper part of a combustion part, it moves downward in a gas passage separated from the combustion part 5 by a gas passage partitioning metal wall 11 and is mixed with air and then, hot air is supplied. An odor adsorbent 10 including an inorganic compound is provided above the combustion part 5 in the gas passage in which the combustion exhaust gas moves downward and an oxidizing catalyst layer 12 is formed on the metal wall 11 in the downstream side of the adsorbent 10 and in the vicinity of the combustion part 5. Then, when the combustion is not done, indoor air is circulated so that the odor is adsorbed on the odor adsorbent 10. Upon combustion, the odor adsorbent 10 is heated by combustion heat to remove the odor and the removed odor is decomposed by an oxidizing catalyst. |
