HAND WASHING APPARATUS USING HIGH-PRESSURE WATER

The present invention relates to a hand washing machine using high pressure water, and more specifically to a hand washing machine using high pressure water that can automatically wash person's hands and can remove bacteria without using components (e.g., a detergent) other than water. According to one embodiment of the present invention, the hand washing machine includes: a washing drum having a predetermined internal space; a first spray unit connected to the washing drum to spray washing water into the washing drum; a water tank connected to the first spray unit and storing predetermined washing water therein; a second spray unit connected to the washing drum to spray a cleaning agent into the washing drum; a cleaning agent tank connected to the second spray unit and storing a predetermined cleaning agent therein; a casing accommodating the washing drum, the water tank, and the cleaning agent tank; a hand entrance opening formed in the upper portion of the washing drum at one side of the casing; an air blowing unit blowing air in a direction toward the center of the hand entrance opening from the inner circumference of the hand entrance opening; a control unit transmitting control signals to the first spray unit, the second spray unit, and the air blowing unit; and an actuation means transmitting an actuation signal to the control unit. When the actuation means is operated, the hand washing machine is controlled through the steps of: operating the first spray unit to spray high pressure water for a predetermined time; operating the second spray unit to spray a cleaning agent for a predetermined time when it is determined that user's hands are not sensed in the washing drum after the water spray step; and operating the air blowing unit to blow air after the water spray step, such that the hands are washed with only the water sprayed in the water spray step.
