Abstract
A mixer-unit is attached to the cold and hot water mains and serves to adjust the quantity and temperature of the water. The mixer unit is not fitted with an operating handle or lever, the adjustment of the water quantity and temperature is achieved by pivoting the water outlet about two independent axes of movement. Disc-shaped regulating elements serve for the independent adjustment of both the water quantity and temperature which are operable by means of a cam connected to the rotatable and pivotable water outlet.
Claims26
A water mixer unit including a valve body (1);
- two water supplies (2 and 3) of different temperatures;
- at least one regulating element for the control of the water quantity and/or temperature, and a water outlet (5) in a water container (6), characterized as:
- that the water quantity and/or the mixing temperature of the water is influenced by the pivoting of the water outlet (5), said regulating element having two water ports in communication with, respectively, said two water supplies, said regulating element being movable in at least two degrees of freedom by said pivoting of said water outlet, with said degrees of freedom of movement controlling, respectively, said water quantity and mixing temperature.
Water mixer unit, including two water supplies of different temperatures;
- at least one regulating element for the control of the water quantity and/or temperature, and a water outlet in a water container, characterized as:
- that the water quantity and/or the mixing temperature of the water is influenced by the pivoting of the water outlet;
- that pivot movements of the water outlet take place both about an almost vertical axis and about a substantially horizontal axis and are so combined that one pivot movement determines the water quantity and the other pivot movement determines the mixing of the water from said water supplies of different temperatures, and thereby determines the temperature of the water outflow;
- that said regulating element includes at least two opposingly slidable parts with planar regulation surfaces, for example, from ceramics, one said slidable part being connected to the pivoting water outlet by a transmission part and another said slidable part being rigidely fixed to the water outlet;
- that the transmission part is connected, either form-locking or fixed, to both pivot movements of the water outlet;
- that the transmission part is connected to a universal joint rotatable about two axes at right angles to each other;
- and that one axis of the universal joint is parallel to one pivot axis of the water outlet but does not coincide with it.

- that said regulating element includes at least two opposingly slidable parts with planar regulation surfaces, for example, from ceramics, one said slidable part being connected to the pivoting water outlet by a transmission part, and another slidable part being rigidly fixed to the water outlet, with the plane of said regulation surfaces being substantially at right angles to a pivot axis of the water outlet;
- and that one of said parts is coupled rotatably about the pivot axis of the water outlet.
