New type of supersonic washer-disinfector using ozone bubbling and silver electrolysis was developed in order to clean many devices and materials such as semiconductors, endoscopes and cut vegetables. This washer has fourteen supersonic oscillators of umbrella shape, which emit supersonic traveling waves along more than two directions and are driven independently by each supersonic transducer. The intensity of supersonic levitation wave in water was measured with a quartz-tube sensor and found to be even all over the aqueous container space. This supersonic levitation washer can evenly clean not only hard materials such as glasses, jewels and metals, but also soft materials such as clothes, plastics, rubbers and bodies. Neither detergent nor disinfectant is necessary, therefore the drainage does not cause any environmental pollution. Disinfection is easy and rapid using ozone oxidation and silver electrolysis. Ozone is produced by the irradiation of 185nm ultraviolet light against air and evolved as micro-bubbles. Electrolysis is carried out using direct current between the positive electrode of net-shape silver plate and the negative electrode of stainless-steel container. This apparatus meets the present demand of cleaning regarding the global environmental conservation.
