A hygienic cleaning device comprising: a water discharging part having a nozzle for performing cleaning of a human part 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 nozzle is advanced frontward from the casing so that a distal end of the nozzle is positioned outside the casing and 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; and the control part is configured to perform a control so as to dispose the water discharging part at a storing position in which that the nozzle is stored in the inside of the casing during a period where neither cleaning of a human part nor the scale removing mode is performed, whereby the casing has an opening portion which allows advancing of the nozzle toward the outside of the casing, the opening portion being formed on a front portion of the casing, characterised in that a shutter is rotatably mounted on the opening portion, the shutter being configured to open or close the opening portion in response to advancing and retracting of the nozzle, whereby in the state where the water discharging part is at the storing position, the water discharging part is retracted to the inside of the casing, and is positioned behind the opening portion and the shutter. a water discharging part having a nozzle for performing cleaning of a human part 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 nozzle is advanced frontward from the casing so that a distal end of the nozzle is positioned outside the casing and 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; and the control part is configured to perform a control so as to dispose the water discharging part at a storing position in which that the nozzle is stored in the inside of the casing during a period where neither cleaning of a human part nor the scale removing mode is performed, whereby the casing has an opening portion which allows advancing of the nozzle toward the outside of the casing, the opening portion being formed on a front portion of the casing, characterised in that a shutter is rotatably mounted on the opening portion, the shutter being configured to open or close the opening portion in response to advancing and retracting of the nozzle, whereby in the state where the water discharging part is at the storing position, the water discharging part is retracted to the inside of the casing, and is positioned behind the opening portion and the shutter.
