<P>PROBLEM TO BE SOLVED: To provide a deodorizing apparatus with easy assembling capable of ensuring a sealing property of a fin catalyst even if a dimension accuracy of a member is not made so high. <P>SOLUTION: The deodorizing apparatus is provided with a cylindrical case 22 with a bottom having a suction part 23 and an exhaust part 24; the fin catalyst 29 inserted into the case 22 and forming an exhaust passage of an exhaust gas; and a heater 25 mounted to a lid 30 for heating the fin catalyst 29. The fin catalyst 29 has a metal plate 26 having a surface carried with a catalyst and formed with the exhaust passage in a swirl shape; and an abutment plate 28 provided so as to cover both ends of the metal plate 26. In the state that a heat insulation material 34 is arranged at an outer side of the abutment plate 28, the fin catalyst 29 is inserted into the case 22 and the heat insulation material 34 is compressed, the lid 30 is applied to the case 22. Thereby, the sealing property of the fin catalyst 29 can be ensured and the assembling is facilitated only by applying the lid 30 to the case 22 even if the dimension accuracy of the member is not made so high. <P>COPYRIGHT: (C)2007,JPO&INPIT |
