TEMPERATURE CONTROL DEVICE FOR FAUCET WHEN FLOW RATE OF FAUCET CHANGE

摘要

The present invention provides a mixed water temperature control device by changing a supply amount of cold and hot water in a faucet. According to an embodiment of the present invention, the mixed water temperature control device by changing a supply amount of the cold and hot water in a faucet includes: a faucet unit having a hot water inlet, a cold water inlet, and an outlet on the bottom surface, wherein an outer surface is connected to a faucet lever; a pipe unit including a hot water supply line supplying the hot water to the hot water inlet, a cold water supply line supplying the cold water to the cold water inlet, and a discharge line in which mixed water discharged from the outlet flows; a flow rate change measurement unit connected to the hot water supply line and the cold water supply line and moving in a piston form between the hot water supply line and the cold water supply line due to difference between a flow pressure of the cold water flowing along the cold water supply line and a flow pressure of the hot water flowing along the hot water supply line; and a temperature control unit connected to the faucet unit and the flow rate change measurement unit to change a linear motion of the flow rate change measurement unit to a rotation motion by being engaged with the flow rate change measurement unit to control an opening rate of the hot water inlet and the cold water inlet, and controlling the temperature of the mixed water discharged through the outlet. The temperature control unit includes: a control rotation plate installed on the bottom of the faucet unit and having a cold water control opening connected to the cold water inlet and a hot water control opening connected to the hot water inlet; a rotation shaft extended to protrude from the bottom surface of the control rotation plate; and a pinion gear connected to the other end of the rotation shaft and connected to a rack gear of the flow rate change measurement unit. The pinion gear rotates by being engaged with the rack gear when the rack gear straightly moves, and the control rotation plate changes the position of the hot water control opening and the cold water control opening.
