WATER SAVING SYSTEM OF SINK

摘要

PURPOSE: A water saving system of a sink is provided to reduce the drain amount of waste water and to reduce the total used amount of water by storing clean waste water in a tank through an opened auxiliary drain port and recycling the waste water from the tank. CONSTITUTION: A main drain port and an auxiliary drain port(5) are formed at both side on the bottom surface of a sink(2). A drain hose(4) is connected to the lower portion of the main drain port to drain waste water while a connecting pipe(8) is extended to the lower end of the auxiliary drain port. A tank(12) is connected to the outside of the connecting pipe, and an additional buffer hose(9) is joined with the lower end of the connecting pipe to be in the tank. The buffer hose has an end closed and plural through holes(10) formed outside to remove strong friction noise when water is supplied into the tank through the auxiliary drain port. A pumping pipe(18) is formed vertically on a side of the tank to connect the inside of the tank with outside. The pumping pipe has a pump(19) for pumping waste water in the tank, and a venturi tube(20) is connected to the upper portion of the pump. To wash out dish, a user operates the pump. The waste water is pumped out of the tank, flowed through the venturi tube and drained out. Therefore, the user washes the dish primarily with the waste water.
