COLD AND HOT WATER DISPENSER

摘要

PURPOSE: A cold/hot water dispenser is provided to increase the use convenience by arranging a cold/hot tap on a higher location than a cold water tank and a hot water tank. CONSTITUTION: A cold/hot water dispenser comprises a first pump(170), a second pump(180), a first ancillary pipe(112), a second ancillary pipe(122), a third electronic valve(113), and a fourth electronic valve(123). The first pump carries the cold water from a cold water tank(110) to a cold water tap(150). The cold tap is installed at a higher location than the cold water tank and discharges the cold water. The second pump carries the hot water from a hot water tank(120) to a hot water tap(160). The hot water tap is installed at a higher location than the hot water tank and discharges the hot water. The first ancillary pipe connects the first pipe(111) to the cold water tank so that the water remaining between the first pump and the cold water tap circulates to the cold water tank by the continuous operating of the first pump. The second ancillary pipe connects the second pipe(121) to the hot water tank so that the water remaining between the second pump and the hot water tap circulates to the hot water tank by the continuous operating of the second pump. The third electronic valve blocks the flow passage of the first ancillary pipe when the cold water tap operates. The fourth electronic valve blocks the flow passage of the second ancillary pipe when the how water tap operates.
