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.

Abstract: The present invention is a spout apparatus including: a spout forming member configured to form a spout; a flow-guiding member provided inside the spout forming member, configured to guide water on an upstream side of the spout; an exposed flow-guiding member provided inside the spout forming member and on a spout side of the flow-guiding member, and exposed on a spout side of the exposed flow-guiding member; and a water channel configured to supply the water to an upstream side of the flow-guiding member. The exposed flow-guiding member and/or the spout forming member are configured to spout water from an outer periphery as an annular stream, among the water spouted from the spout. According to the above spout apparatus, the flow-guiding member can be effectively protected, and high guiding characteristics can be achieved in particular at an outer periphery of the spout.
