Water mixing valve

摘要

A water mixing valve having two water inlets, a mixing chamber, a rotatable control member having openings for controlling flow from the water inlets to the mixing chamber, the water mixing valve further including a water outlet (6) from its housing and a temperature sensor (30) adjacent the outlet to enable electronic control of the output temperature, wherein the walls of the outlet are shaped around the temperature sensor such that of six possible perpendicular orientations of the water mixing valve, in at least three mutually perpendicular orientations and any orientation in between, the temperature sensor remains submerged in water when water is allowed to drain from the water outlet by gravity and the water mixing valve further including a zero position detector (112), a zero position indicator (110) being provided on the control assembly for detection by the zero position detector such that, when the zero position detector detects the zero position indicator at a predetermined position, it is determined that the openings are at a preselected position relative to the inlets.
