<p>PROBLEM TO BE SOLVED: To provide an adsorbent quickly adsorbing and deodorizing an unpleasant offensive smell component in a toile, regeneratable by heating for eliminating maintenance such as the replacement. SOLUTION: A first adsorbent 23 for carrying a metallic oxide including at least one kind of manganese, copper and cobalt is arranged on the upstream side in a ventilation flue. A second adsorbent 24 for carrying an adsorbent including at least one kind of zeolite, silica and alumina on a base material generating heat by energizing is arranged on the downstream side. The second adsorbent is regenerated by heating by energizing a base material according to an adsorbing situation of the adsorbent.</p> |
