WATER SAVING DEVICE FOR PREVENTING WASTE FLUSH OF FLUSH TOILET

PURPOSE:To veil excreting sound, eliminate the waste of cleaning water and reduce cost by making water saving device for preventing a wasteful flush with a nozzle control means, a sensor means, a device for generating a simulated water flow sound and a control unit. CONSTITUTION:A water saving device for preventing wasteful flush consisting of a flushing nozzle 1a, a nozzle control means 10, a sensor means 30, a water flow sound generator 44 and a control unit 40 is installed. When a situation requiring washing of a toilet bowl is not detected by a sensor means 30, a control unit 40 forces a nozzle control means 10 to make false operation and a water flow sound generator 44 is operated to generate a simulated water flow sound for a fixed time. When a situation requiring washing is detected, valve opening operation is made by the control means 10 to open the valve of the nozzle 1a. Moreover, a counter means 45 records the number of outflow times of cleaning water and the number of generation times of simulated water flow sound and catches water saving effect caused by the generation of simulated water flow sound as numerical values.
