Traditionally, the water required for different applications is drawn from the water supply network using separate and independent taps or valves, whereby the taps or valves are connected in parallel. This means that if water is needed in one object, the tap or taps leading to that destination will be opened and, at the end of use, closed, while the taps leading to all other targets may be completely closed or open, regardless of that destination. A clear exception to this general and customary principle is the mixing tap configuration mentioned in the introduction. In this known configuration, the cold and hot water from the inlet pipes can be mixed when the lever for the hand lever is raised, i.e. with the lever 20 in the open position. The mixed water then flows into the ejector sections of the faucet. If the closure-opening member of the hand shower section is attached, the water in the lever faucet will flow through the side-flow channel into the spout and further into the wet area, such as: T: Hand wash basin. If, on the other hand, the closure-opening member of the hand shower section is flowing water through the flow duct vi-clean to the interconnector and further from the hand shower section to its ···: v. 25, while no more water is flowing through the side flow channel. Here, therefore, * «the water required for two different sites is drawn from the co-operating taps, which are * interconnected through a pipe independent of the plumbing network. The ice cream thus has common mixing closure parts for both applications in the lever cock structure itself and a closure opening member for selecting which of the 30 destinations the water will eventually go to. In this case, the closure-opening members and the closure-opening member ..!: * Are thus interlocked.

• * * • *. ···, It is also known to initiate a flow of water to a desired destination via electronic or electronic * equipment. In these solutions, the electric energy provided by the electric or electronic device 35 tons opens and closes the \ * ·: valves containing the electrical actuators, causing the water to flow and run out to the destination. When triggered to open and close valves, such electrical or electronic equipment receives either push buttons or sensors located at appropriate locations, such as photoelectric cells 117173, etc. One of a plurality of photoelectric sensor solutions is described in U.S. Pat. No. 6,294,786, EP 0 387 396.

It is an object of the invention to provide an arrangement whereby the collection of water required for two different sites from cooperating faucets which are interconnected via a connecting pipe independent of a water mains network can be controlled elsewhere, either mechanically or electronically or electronically. Another object of the invention is to provide such a solid state, in which a possible excitation for electrical or electronic control can be generated at any desired location. It is a third object of the invention to provide such a rigid arrangement in which existing structures can be used as much as possible.

These objects may be achieved by a combination of taps according to the invention, which is characterized in what is defined in the characterizing part of claim 1.

It has now surprisingly been found that the control of the water inlet to two objects, for example the wash basin and the hand shower, can be simply and effectively tracked by using an ejector mixing faucet with a hand shower unit with a shut-open element and adding only one electronically or electronically controlled ie manual vent-: T: brick. In this arrangement, the valve electrical or electronic control circuit sensor: and / or the operating switch may be located at any desired location.

In the following, the invention will be described in detail with reference to the accompanying figure,. which illustrates a preferred embodiment of the invention such that the mixing tap size; the insert is depicted in longitudinal section, whereby the mixing shut-off opening members and the associated ejector portions with ducts are visible, the hand shower and the connecting tube 30 are viewed from the side and the hand shower closure opening is shown with dashed lines, and .. * ** electrical / electronic components are schematically illustrated.

First, the starting manual mixing tap assembly 2 comprises * ··· [mixing shut-off-opening portions 5, which are led by the inlet water pipes 15, 16 in conventional flow directions FI, F2. The inlet water pipes are the hot water pipe 15 and the cold water pipe 16 and the closure opening parts 5 are, in this embodiment, parts of the lever cock. It will be appreciated that said shut-off opening portions 5 may also be, for example, valve parts corresponding to a thermostatic faucet or separate shut-off valves for hot and cold water. Thus, the shut-off opening members 5 may be any known or new and suitable tap construction which is capable of closing and opening the connection to the inlet water pipes and of mixing hot and cold water. Both lever taps and thermostatic taps as well as separate hot and cold taps are known per se and will not be further described. In the mixing tap assembly 2, the closure opening portions 5 are followed by ejector portions 6 in the flow direction 5, which also includes a downstream passageway 3 and a side flow passageway 4. The ejector portions comprise an actual ejector nozzle 26 in which direction and extension. Between the ejector nozzle 26 and the downstream duct 3, said lateral flow duct 4 is formed such that a small gap is formed between the ejector nozzle and the downstream duct. Further, the mixing tap assembly 2 has a connecting pipe 19 in fluid communication with the continuous flow cavity passage 3, and at its outer end a closure opening member 9 when the closure opening member 9 is closed and the closure opening portion 5 of the assembly is open. through the ejector portions, more specifically through the ejector nozzle 26 to the side flow passage 4 - because flow continuation through the flow passage 3 is blocked when the closure opening member 9 is closed - and from there to the spouts 15 to engage 13 and outlet nozzle 24 to the user. When the closure-opening member 9 is open and the assembly closure-opening portions 5 are open, water flows through the closure-opening portions into the ejector portions, more specifically through the ejector nozzle 26 to the flow channel 3 - because there is less flow resistance thence to the connecting pipe 19 and 20 further through the closure-opening member 9, i.e. to another application. In this first mode of operation, the water has a flow direction F4 in the connecting pipe 19. For the second application, the assembly may include, for example, a hand shower section 8 or other water I 1 ''. an inlet within which the closure-opening member 9 is located. The closure-opening member 9 has a purely closing function and an opening function, so that any known or new valve or valve suitable for the purpose can be used as the closure-opening member. This is how

Ien will not explain it further.

According to the invention, in addition to the aforementioned mixing tap assembly * 2, the mixer valve assembly 1 comprises a branching piece 7. The branching piece 7 may be, for example, a conventional T-piece having a direct portion in the connecting tube as shown in the figure. The V water pipe 14 does not draw water but supplies additional water to the mixing mixer 2 of the mixer mix 1, as indicated by arrow F3 in the figure. For the control of the auxiliary water supply, the auxiliary water pipe 14 must be controlled by a valve 11. In the simplest embodiment; 35, the control valve 11 is actuated directly by manual operation, i.e. it is exclusive fold manual operation valve as indicated by dotted lines in the figure. In a preferred embodiment, the mixer assembly 1 further comprises an electrical control unit 12 with a sensor 21 and / or a switch 22, and this control unit 12 is connected to the control valve 117 for its shut-open function. In this case, the controlled valve can be controlled within the design range, distance, and design excitation. When the mixing shut-off members 5 are closed and likewise the shut-off member 9 is closed, water can be directed through the spout 13 and the outlet nozzle 24 5 to the first application by opening the controlled valve 11 without the user having to touch the mixing tap assembly 2. In this second operating state, water has a flow direction F5 in the connecting pipe 19, which is thus opposite to the flow direction F4 of the first operating mode. The situation described above, both the closure-opening members 5 and the closure-opening member 9 are closed and the water supply 10 is controlled by a controllable valve 11 is an essential feature of the invention. It is to be understood that the opening of the closure-opening member 9 causes additional water to flow also to another application. The mixer valve assembly 1 according to the invention works with many types of closure opening parts and closure opening member as long as the mixing tap assembly has ejector portions and the closure opening portions and closure opening member are connected to each other.

The sensing element 21 of the control unit 12, such as a user sensing photoelectric array or other sensor solution, may be located to activate in the wet area AI of the outlet nozzle, but preferably the sensing element 21 is located elsewhere, i.e., tracked to activate outside the wet region A1 of the first application.

This wet zone refers to the area where the user can move his hands while washing them in the stream of water from the outlet nozzle 24. Similarly, the switch ... 22 is preferably positioned closer to the wet area A2 of the second application, such as the hand shower area 8 of the hand shower section 8, than the mixing tap assembly 2. In this case, the actuator 11 can be opened by either touching the switch 22 by moving: V 25 something in contact with the sensing area of the sensor 21. The closing of the controlled valve 11 may be accomplished by a timer tracked on the control unit 12 or by some other means of user operation.

The mixer mixer 1 may further comprise a mixing tap 17 'having a constant mixing ratio or a thermostatically or similarly functioning mixing tap 17' in said auxiliary water pipe 14 prior to the control valve 11, whereby both a hot water pipe 15 and a cold water pipe 16 are provided. Alternatively, the auxiliary water pipe 14 is connected 17 "to either of the inlet water pipes 15, 16, preferably to the cold water pipe 16, whereby the overall construction:: * is remarkably simple. The use of cold water is defensible because. 35 in most situations, short-term water intake does not have the time to bring in the right temperature *; piping, however. The above-described functions of the mixing tap assembly 2, which are controlled by the closure-opening parts 5 and the closure-opening member 9, remain in their original form.
