Abstract
An automatic hair washer having a basin with a plurality of washing nozzles for spouting wash water into the basin, a hot water storing tank for storing wash water, a pump for pumping out wash water from the hot water storing tank to the washing nozzles, electromagnetic valves for controlling spouting of the wash water from the washing nozzles, electromagnetic valve control means for controlling the electromagnetic valves so that wash water flows from at least one of the washing nozzles during a predetermined period and, by opening the electromagnetic valve of another of the washing nozzles while wash water flows from the at least one washing nozzle, wash water flows from both washing nozzles in an overlapping manner. A pump control means is also included for controlling the pump so as to decrease the hydraulic pressure of wash water supplied to the at least one washing nozzle just before opening the electromagnetic valve of another washing nozzle and to gradually increase the hydraulic pressure of wash water supplied to another washing nozzle to be a predetermined hydraulic pressure at the same time that the electromagnetic valve of the another washing nozzle is opened.
