<P>PROBLEM TO BE SOLVED: To provide a deodorization device which assures a sealing performance, at the same time, improves a thermal insulation, and maintains a deodorization capability. <P>SOLUTION: The device comprises a catalyst fin 44 forming a deodorizing passage 55 by making a belt-like flat plate spiral, and at the same time, supporting a catalyst on its surface, a bottomed cylindrical deodorization vessel 46 housing the catalyst fin 44 with a gap 52 to its outer hull, a catalyst heating means 48 inside the deodorization vessel 46, sealing members 51A, 51B respectively applied to both spiral-shaped ends of the catalyst fin 44, and a vessel lid 49 covering an opening of the deodorization vessel and pressing both sealing members to both spiral-shaped ends of the catalyst fin. Thereby, the vessel lid 49 can press the sealing members 51A, 51B to the whole spiral-shaped ends of the catalyst fin 44 to assure the sealing performance, at the same time, improve the thermal insulation, and maintain the deodorization capability. <P>COPYRIGHT: (C)2007,JPO&INPIT |
