PROBLEM TO BE SOLVED: To provide a deodorization device into which a dust collection unit is integrally incorporated, so that powder dust leaking from the dust collection unit into an enclosure in which the deodorization device is installed is collected and accumulated by the dust collection unit without leakage outside the deodorization device.SOLUTION: In an enclosure 3 having one or a plurality of inlets 1 for suctioning ambient air in a lower part and an outlet 2 for blowing out the clean deodorized air 14 in an upper part, a deodorization device 8 is provided including a fan 4, a dust collection unit 5, a granular active carbon filter 6, and an HEPA filter 7 which are layer-stacked from upstream toward downstream. A concave ventilation space 10 extending to the inlet 1 is provided between the outer peripheral side and the underside of the deodorization device 8 and the inner wall face 9 of the enclosure 3. The downstream opening edge 11 of the HEPA filter 7 and the inner wall face of the enclosure 3 are sealed with a seal 12.COPYRIGHT: (C)2014,JPO&INPIT【課題】脱臭装置に集塵ユニットを一体に組み込み、該集塵ユニットから前記脱臭装置を設置した筐体内へ漏洩した粉塵を、該脱臭装置外部に漏洩することなく、集塵ユニットに捕集・蓄積させる。【解決手段】下方部に外気を吸込む1個または複数個の吸込み口1と、上方部に脱臭された清浄空気14を吹出す吹出し口2を備えた筐体3内に、上流側より下流側へ向けて、ファン4、集塵ユニット5、粒状活性炭フィルター6およびHEPAフィルター7を積層重合して脱臭機構8が構成され、且つ該脱臭機構8の外周側面および底面と前記筐体3の内側壁面9間に、前記吸込み口1に連なる凹状の通気空間10を備えると共に、前記HEPAフィルター7の下流側開口端縁11と筐体3の内側壁面とをシール12して密封して形成する。【選択図】図1
