Abstract
Device for controlling a washing water flow passage in a dish water for controlling the washing water supplied to arms for spraying washing water to dishes. The device for controlling a washing water flow passage includes an inlet tube, first, second, third, and fourth tubes, first and second outlet tubes, a ball, a ball seat, and a valve. The first tube is extended upward from the inlet tube, and the second tube is extended slanted upward from the inlet tube. The third tube is extended upward vertically from a top of the second tube, and the fourth tube is connected between the first tube and the third tube in a downward slanted direction. The first outlet tube is formed on a top of a part where the first tube and the fourth tube are joined, and the second outlet tube is formed on a top of the third tube. The ball seat is provided to an inside of the inlet tube, and the valve is provided to one side of the first tube for blocking pass of the ball. The ball controls the flow passage of the washing water supplied to arms that sprays the washing water as the ball moves in the first, second, third, or fourth tube by a washing water pressure and gravity and opens/closes the first or second outlet tube selectively.
