DEODORIZER

PURPOSE: To simplify assembly of a deodorizer by providing circular vertical wall, etc., on the substrate of the deodorizer for a water closet, at the same time, mounting a cover and a fan housing thereon, and combining them to form a ventilating duct. CONSTITUTION: A circular vertical wall 52 is provided on the substrate 45 of a housing for a deodorizer 19 installed to the rear of a water closet, a cover 53 is covered thereon, and a suction duct 48 is formed of the substrate 45, vertical wall 52 and cover 53. The housing 56 of a deodorization/ventilation fan unit 47 of the deodorizer 19 is mounted on the cover 53, and an exhaust duct is formed of the cover 53 and fan housing 56. Bad odors in the water closet is sucked from a suction port 46 of the substrate 45, and air deodorized by the deodorization/ventilation fan unit 47 is exhausted from an exhaust duct 46. By the constitution, the deodorizer can be efficiently assembled to reduce cost.
