To provide a water spouting device capable of switching between spouting and stopping, flow volume adjustment, and spouted water temperature adjustment with a single operating portion. The present invention is a water faucet device () furnished with a flow volume adjustment function and a temperature adjustment function, including: an operating portion () capable of being pressed and rotated by a user; and flow volume/temperature adjustment means (), whereby in a stopped water state, spouting is commenced when the operating portion of this flow volume/temperature adjustment means is pressed; in a spouting state, spouted water flow volume is changed when the operating portion is pressed continuously for a predetermined long-press determining time; and water flow is stopped when pressing of the operating portion ceases in less than the long-press determining time.

Water faucet device

A water-and-hot-water mixing device includes a mixing valve unit which mixes hot water and water and discharges mixed water therefrom, an operation part which sets a predetermined temperature, a mixed water thermistor which detects a temperature of mixed water, a hot-water thermistor which detects a temperature of hot water supplied to the mixing valve unit, and a controller which performs a feedback control of a discharge water temperature by controlling the mixing valve unit. The controller starts the feedback control when the controller determines that a change amount of the temperature of the hot water per unit time detected by the hot-water thermistor is not more than a fixed value and the temperature of the hot water detected by the hot-water thermistor is not lower than the predetermined temperature.
