摘要： A sanitary cleaning device (1) including a nozzle (40), a water supply path (50), a backflow prevention mechanism (90), and a solution provision unit (100). The backflow prevention mechanism includes a tank (91) provided on the water supply path, a water inlet port (92) that is communicated with an upstream water supply path (51) on the water supply path and through which water flows into the tank, a water outlet port (93) that is communicated with a downstream water supply path (52) on the water supply path and through which water in the tank flows out to the downstream water supply path, and an overflow port (94) provided to form an air gap between the overflow port and the water inlet port. The solution provision unit includes a provision port (121) through which acid solution is provided by the user, a solution supply path (113) through which the acid solution provided through the provision port circulates, and a solution inlet port (112) through which the acid solution flowing through the solution supply path flows into the tank. The solution supply path of the solution provision unit includes an expansion part in which a flow-path cross-sectional area increases toward the solution inlet port (112).

摘要： According to one embodiment, a toilet device includes a flush toilet, a toilet seat, a spray device, a detecting sensor, and a controller. The flush toilet includes a bowl. The bowl includes a flush region and a non-flush region. The controller executes a pre-mist mode and an after-mist mode. The pre-mist mode includes automatically controlling the spray device, spraying the mist onto the flush region and the non-flush region, and forming a water droplet or a water film by causing the mist to accumulate in the flush region and the non-flush region. The after-mist mode includes automatically controlling the spray device to rinse away the water droplet or the water film formed in the non-flush region in the pre-mist mode by increasing a volume of the water droplet or the water film.

摘要： Provided is a hygienic cleaning device which can suppress applying of a scale removing agent to a member disposed inside of a casing.
The hygienic cleaning device includes: a water discharging part having a nozzle and provided for discharging water; a water supply passage provided for supplying the water to the water discharging part; a tank provided to the water supply passage; a removing agent charging part capable of charging a removing agent which dissolves a scale precipitating in the water supply passage into the tank; a control part provided for performing a scale removing mode where the scale which precipitates in the water supply passage is dissolved by the removing agent charged into the tank; and a casing provided for housing the water discharging part, the water supply passage, the tank, and the control part, wherein the control part is configured to perform a control so as to dispose the water discharging part at a scale removing position where the removing agent is discharged from the water discharging part toward the outside of the casing while the control part performs the scale removing mode.

摘要： A sanitary cleaning device (1) comprising a nozzle (40), a water supply path (50), a backflow prevention mechanism (90), a solution provision unit (100), and a control unit (200). The backflow prevention mechanism includes a tank (91) provided on the water supply path, a water inlet port (92) that is communicated with an upstream water supply path (51) on the water supply path and through which water flows into the tank, a water outlet port (93) through which water in the tank flows out to a downstream water supply path (52), and an overflow port (94) provided to form an air gap between the overflow port and the water inlet port. The solution provision unit supplies acid solution provided by a user to the tank. When having received an instruction to transition to a scale removal mode, the control unit executes scale removal processing of filling the downstream water supply path and the nozzle with the acid solution accumulated in the tank and then discharging the acid solution. The control unit executes water discharge processing of discharging water in the tank before the scale removal processing.
