Abstract: A toilet space deodorizing device includes an intake part forming an intake port; an exhaust part forming an exhaust port; a fan device intaking air through the intake port; a water deodorizing part provided inside a deodorizing air channel, the deodorizing air channel linking the intake port and the exhaust port and allowing air to flow, the water deodorizing part using water to deodorize the suctioned air; a water supply part supplying water to the water deodorizing part; and a drainage part forming a drainage port, the drainage port draining water from the water deodorizing part into a drainage receptacle. The drainage port is positioned between the water deodorizing part and the water supply part. The water supply part supplies the water to the water deodorizing part via the drainage port.

Abstract: A toilet space deodorizing device includes an intake port part forming an intake port, an exhaust port part forming an exhaust port, a fan device, a water collecting part provided inside a deodorizing air channel, a water supply part supplying water to the water collecting part, a drainage part forming a drainage port, a negative pressure generation device forming a negative pressure in the water collecting part, and a controller controlling a driving of the negative pressure generation device. The controller dries the negative pressure generation device to generate a negative pressure. The water supplied from the water supply part is collected in the water collecting part due to air flowing into the water collecting part and pushing on the water supplied from the water supply part by the negative pressure.
