<p>PURPOSE: To efficiently wash hands by providing each exclusive detection part for three functions of the discharge of soap liquid, that of wash-hand water, and drying, and making different the wavelength of a ray used by adjacent detection parts. CONSTITUTION: A function mount part 7 is erected on the upper surface of the rear part of wash-hand equipment 6, and a soap liquid discharge nozzle 3d, a wash-hand water discharge port 4e, and a hot air nozzle 5c are provided at the front. Then, detection parts 1a, 1b, and 1c using a visible light sensor are arranged close to each device exclusively for each function. Then, the wavelength of visible light to be used is made different for adjacent detection parts out of the detection parts 1a, 1b, and 1c, thus avoiding the mutual interference of the detection pasts 1a, 1b, and 1c and operating a drier accurately.</p> |
