Abstract

PROBLEM TO BE SOLVED: To change the flow rate of water and secure the power of water discharge even though the flow rate is low by providing the means of water supply, air supply, detection and variable water flow. SOLUTION: A switch 1 is attached, as a low flow rate detecting sensor 6 and a high flow rate detecting means, to a faucet 13. Next, the exhaust reaches the exhaust port 5 via a bubble mixing portion 10 from a water inlet pipe 11 to a first passage for high flow rate or to a second passage for low flow rate. Next, to a bubble mixing portion 10, an air supply device 9 is connected through an air supply pipe 12. Also to the first passage and the second passage, a first shut-off valve 3 and a second shut-off valve 7 are connected. Further, a switch 1, a detector sensor 6, an air supply device 9 and a shut-off valve 3 are respectively connected to a control portion 2. Thus, when hands or the like come near the sensor 6, the valve 7 opens and small discharge can be obtained without requiring large discharge. Also, when large discharge is needed and the switch is operated, the valve 3 opens and large discharge can be obtained. In this way, water can be saved considerably.
