PROBLEM TO BE SOLVED: To provide a deodorization device for toilet space capable of effectively deodorizing both smell components having high water solubility and a smell component having a water solubility lower than the above-mentioned smell components but having high oxidation decomposability, while disposing a water deodorization part configured to store water and an oxidation catalyst in one air channel.SOLUTION: A deodorization device for toilet space comprises: a fan device which is provided within a deodorization air channel； a water storage part which is capable of storing water therein and in which a surface of the stored water forms a part of the deodorization air channel； an oxidation catalyst provided within the deodorization air channel； and a control part which controls water supply to the water storage part by a water supply part and suction by the fan device. The control part executes a first water supply mode in which water of a first water quantity is supplied to the water storage part and a second water supply mode in which water of a second water quantity less than the first water quantity is supplied to the water storage part.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2020,JPO&INPIT【課題】水を溜める構成の水脱臭部と、酸化触媒とを１つの風路中に配置しつつ、水溶性の高い臭気成分と、これら臭気成分より水溶性は低いが酸化分解性の高い臭気成分の両方を効果的に脱臭することができるトイレ空間用脱臭装置を提供する。【解決手段】トイレ空間用脱臭装置は、脱臭風路中に設けられたファン装置と、水を溜めることが可能で溜めた水の水面が脱臭風路の一部を形成する水溜め部と、脱臭風路中に設けられた酸化触媒と、給水部による水溜め部への給水、及び、ファン装置による吸気を制御する制御部とを備えている。制御部は、水溜め部への第１水量の給水を行う第１給水モードと、水溜め部への第１水量より少ない第２水量の給水を行う第２給水モードとを実行する。【選択図】図７
