PROBLEM TO BE SOLVED: To provide a deodorizer having an enhanced heating efficiency of a catalyst filter, ensuring heat radiation to the catalyst filter even with a radiator plate having a portion away from a heater, suppressing heat transfer to the peripheral part of the radiator plate, which has no contribution to the heat radiation to the catalyst filter.SOLUTION: A radiator plate 351 includes: a heat transfer enhancing part 351a in contact with a heater 352, which transfers the heat applied from the heater 352 to the entire radiator plate 351 a catalyst filter opposing part 351b opposed to a catalyst filter 33, which is continuously formed with the heat transfer enhancing part 351a, and an extension part 351c continuously extending from the catalyst filter counter part 351b. The catalyst filter counter part 351b has a plurality of ventilation holes 351d for ensuring ventilation of air. The extension part 351c has a plurality of heat transfer suppressing holes 351f for suppressing heat transfer from the heater 352 to the peripheral part 351e of the radiator plate 351 through the heat transfer enhancing part 351a. The extension part 351c is in contact with a wind shielding member 37 which blocks the heat transfer suppressing holes 351f for cutting off the ventilation.COPYRIGHT: (C)2015,JPO&INPIT【課題】放熱板にヒータから離れた部分があっても、触媒フィルタへの放熱を確保し、触媒フィルタへの放熱に寄与しない放熱板の周縁部への伝熱を抑えて、触媒フィルタの加熱効率を高める脱臭機を提供すること。【解決手段】放熱板351は、ヒータ352が当接されヒータ352から加わる熱を放熱板351全体に伝熱する伝熱促進部351aと、伝熱促進部351aと連続的に形成され触媒フィルタ33に対向する触媒フィルタ対向部351bと、触媒フィルタ対向部351bから連続的に延長される延長部351cとを備え、触媒フィルタ対向部351bは、空気の通風を確保する複数の通風孔351dを有し、延長部351cは、ヒータ352から伝熱促進部351aを介して放熱板351の周縁部351eへの伝熱を抑止する複数の伝熱抑止孔351fを有し、延長部351cには、伝熱抑止孔351fを閉塞し通風を遮断する遮風材37を当接させた。【選択図】図4
