Abstract: A washing device for washing a portion of a user's head includes a discharge section which discharges a cleaning liquid into a washing cap attached to a portion of a user's head, and a recovery section which drains the cleaning liquid out of the washing cap so as to recover it. The device again discharges the cleaning liquid recovered by the recovery section from the discharge section, and recirculates the cleaning liquid so as to wash the portion of the user's head covered by the washing cap. When the cleaning liquid is dispersed into the washing cap, the cleaning liquid passes through a nozzle unit so that a lot of microbubbles are generated in the cleaning liquid. The microbubbles are very fine air bubbles, and can remove fine particles of dirt down to the order of a few microns but do not damage the user's scalp and hair.
Abstract: In a scalp washing device a droplet preventing plate is provided positioned between a user's scalp and face, a nozzle having a single discharge port which discharges hot water to the scalp side of the droplet preventing plate is disposed, and hot water discharged from the discharge port of the nozzle is dispersed along the droplet preventing plate so as to be supplied to the user's scalp. For this reason, the flow rate of the hot water is reduced during the dispersion along the droplet preventing plate, and at the time when the hot water is separated from the edge of the droplet preventing plate and is supplied to the user's scalp, the hot water is supplied slowly to the entire scalp, and droplets are not generated. Even if a small gap is generated between the droplet preventing plate and the user's face, the droplets do not leak to the user's face, wetting it.
