Abstract

The invention relates to a mixing device for tap water, comprising a mixing valve and a flow control valve that can each be actuated by a spindle and are arranged one behind the other. The device is characterized in that sensors (21, 22) are provided for determining the volume and temperature of the water flow, the sensors being connected to a control and regulating device used to adjust the volume and temperature of the water flow. A temperature sensor (22) is arranged in the flow control valve (4), for determining the temperature of the volume of water flow guided through the mixing valve (5).

Claims

1. Mixing device for tap water, comprising a mixing valve and a flow control valve, which can be activated by way of a spindle, in each instance, and which are disposed in series one behind the other, wherein both the mixing valve (3) and the flow control valve (4) have a head piece (31, 41) through the center of which a spindle (32, 42) radially guided by it passes, and into which at least one window (311) is introduced on the side, and which accommodates an inlet disk (34, 44) having two passage openings (351, 451) on its side opposite the spindle (32, 42), whereby the through-flow direction of the water amount stream in the flow control valve (4) is opposite the through-flow direction in the mixing valve (3) and wherein sensors (21, 22) for determining the water amount stream and temperature are provided, which are connected with a control and regulation device by way of which the through-flow amount and temperature of the water amount stream can be set, whereby a temperature sensor (22) for determining the temperature of the water amount stream supplied by way of the mixing valve (5) is disposed in the flow control valve (4).

2. Device according to claim 1, wherein the flow control valve is configured as a multi-port valve (4).

3. Device according to claim 2, wherein the multi-port valve (4) is configured in such a manner that not only the assignment of the out-flow to be supplied but also the through-flow amount of the water amount stream can be set by way of the spindle (42).

4. Device according to claim 1, wherein the mixing valve is structured in such a manner that in the closed state of the mixing valve, mixing of the amount streams of the in-flow lines to which it is connected is prevented.

5. Device according to claim 1, wherein mixing valve (3) and flow control valve (4) are connected with one another by way of a line (13), in which line a through-flow sensor (21) for measuring the water amount stream is disposed.

6. Device according to claim 1, wherein the temperature sensor (22) is disposed in the in-flow of the flow control valve (4).

7. Device according to claim 6, wherein the temperature sensor (22) is disposed in the spindle (42) of the flow control valve (4).

8. Device according to claim 1, wherein the mixing valve (3) is connected with a drive (5), by way of which it can be activated and which is connected with the control and regulation device.

9. Device according to claim 1, wherein the flow control valve (4) is connected with a drive (6), by way of which it can be activated and which is connected with the control and regulation device.

10. Device according to claim 8, wherein at least one drive (5, 6) comprises an electric motor that drives a shaft (51, 61) that is connected with the spindle (32, 42) of the mixing valve (3) or flow control valve (4), respectively, by way of a gear mechanism (52, 62).
