Abstract

A sanitary fitting having a housing with at least one mixing unit for mixing a cold water and a hot water into a mixed water, wherein the mixed water can be directed through a first flow path and a second flow path to a spout of the housing, and wherein the first flow path can be at least partially closed by a first valve and the second flow path can be at least partially closed by a second valve, so that an outflow of the mixed water from the spout can be controlled by means of the first valve and the second valve independently from one another.

First claim

What is claimed is:

1. A sanitary fitting comprising:
a housing with a first mixing unit for mixing a cold water and a hot water into a first mixed water and a second mixing unit for mixing the cold water and the hot water into a second mixed water, the first mixing unit and the second mixing unit mixing the cold water and the hot water independently from one another;
a spout; and
a first flow path adapted to facilitate flow of the first mixed water to the spout of the housing and a second flow path adapted to facilitate flow of the second mixed water to the spout of the housing, and
wherein the first flow path is adapted to be at least partially closed by a first valve and the second flow path is adapted to be at least partially closed by a second valve so that an outflow of the first mixed water or the second mixed water from the spout is controllable by the first valve and the second valve independently from one another,
wherein the first valve and the second valve are connected in parallel with one another and the first valve is connected in series with the first mixing unit and the second valve is integrated with the second mixing unit, and
wherein a single cold water inlet and a single hot water inlet are provided within the housing, the cold water inlet dividing into a first cold water flow path that flows to the first mixing unit and a second cold water flow path that flows to the second mixing unit, and the hot water inlet dividing into a first hot water flow path that flows to the first mixing unit and a second hot water flow path that flows to the second mixing unit.

2. The sanitary fitting according to claim 1 , wherein the first valve is an electric valve, an electromechanical valve, or a solenoid valve.

3. The sanitary fitting according to claim 1 , wherein the first valve is controllable by a sensor.

4. The sanitary fitting according to claim 3 , wherein the sensor is located outside the sanitary fitting.

5. The sanitary fitting according to claim 1 , wherein the second valve is a mechanical valve.

6. The sanitary fitting according to claim 1 , wherein the second valve is actuated with an actuator.
