Abstract: A body 1 is constructed by mounting a purifier cartridge 23 in a cold-water passage 7 and is equipped with a purified water handle 16 for opening and closing a branch passage leading from the cold-water passage 7 to the purifier cartridge 23. To this body, there is mounted a base 9 which includes a valve functioning part 11 for adjusting the mixing of cold water and hot water coming through the cold-water passage 7 and a hot-water passage 8, and the flow rates of the cold water, the hot water and the mixed water by operating a lever 15. A spout 10 spouts therefrom the cold water, the hot water, their mixed water adjusted by the valve functioning part 11, or the purified water. The purified water handle 16 and the valve functioning part 11 are provided separately, and hence they can be individually replaced when they fail.

Abstract: The invention relates the mixing valve for controlling the mixture of hot and cold water. The valve takes the form of a fixed and movable plate. A recessed guide groove in the movable plate is formed as a blind groove cooperating with hot and cold water ports and an outlet in the fixed plate. The guide groove has several branches arranged to variably connect to the hot and cold water ports in different relative positions of the movable and fixed plates.

Abstract: A water mixing cock has a noise-preventing structure and comprises a fixed plate, an opposing movable plate valve, a hollow chamber in the movable plate valve, a valve operator for rotating the movable plate valve so that either hot or cold or mixed water is allowed to flow through the hollow chamber, a discharge water passage in communication with the hollow chamber, and a variable escape groove for communicating the hollow chamber and the discharge water passage with each other only when hot water is allowed to flow through the hollow chamber. The noise-preventing structure is a sound arresting member disposed in an inlet portion of the movable plate valve in such a manner that noise occurring when the movable plate valve is rotated by the valve operator is minimized.
