EP2686496B1 - Sanitary fitting comprising a housing and a control unit - Google Patents

Description

The invention relates to a "sanitary fitting with a fitting housing and a control unit" according to the preamble of claim 1.

For example, from the publications DE 100 22 350 A1 or DE 10 2006 060 929 B4 Sanitary fittings with a fitting housing and a control unit known, wherein a shut-off valve is disposed within a valve holder. The valve holder is and remains firmly connected to the mounting location of the valve. The installation site can in this case be a sanitary body such as a sink, etc. or a worktop.

In contrast, the valve body can be easily detached from the valve holder, at the same time shut off or lock the water pipes one or more shut-off valves. Accordingly, the water pipes are opened at the same time when connecting the valve body to the valve holder.

These fittings, for example, allow maintenance or repair of individual components of the fitting, such as e.g. Mixing valve, dirt filter or electrical fittings also replace the batteries / other electrical components without water leaking from the lines and without the usually arranged below the sink angle valves of the water supply lines must be closed.

This is advantageous since, for example, in the case of bathtubs or the like, such angle valves are not (readily) accessible or are not available. The latter applies especially in the public or semi-public space where such angle valves would be manipulated or even damaged by vandalism.

Especially for the applications in public or semi-public space, however, easily disassembled fittings mentioned above are not applicable due to the vandalism problems, since they would be damaged or even removed within a short time.

From the pamphlets DE 100 22 350 A1 . DE 10 2006 060 929 B4 such as JP 2008 248 474 A Various sanitary fittings are already known.

The publication JP 2008 248 474 A discloses a sanitary fitting according to the preamble of claim 1.

The object of the invention is to propose a sanitary fitting of the type mentioned, which can be maintained or repaired with very little effort, especially in applications where the requirements in terms of vandalism are of considerable importance.

The object is achieved by a sanitary fitting with the features of claim 1. The measures mentioned in the dependent claims advantageous embodiments and modifications of the invention are possible.

Accordingly, a sanitary fitting according to the invention is characterized, inter alia, by the fact that at least one fitting base body and a housing opening releasable from the fitting body cover covering a housing opening for opening the valve body for maintenance and / or service purposes includes that within the fitting body at least one a second Actuator having shut-off device is provided for shutting off the water line and that the second actuator is actuated by the fact that the first actuator is disassembled, so that at the same time the second actuator is closed.

With the help of the mounting cover according to the invention in combination with the second, within the firmly fixed at the installation site valve body actuator, preferably shut-off valve, individual or all relevant components of the valve can be serviced or replaced / repaired. In this case, the second actuator preferably blocks the water flow or the water pipe / water pipes in Advantageously, so that downstream hydraulic and possibly electrical components such as dirt filter, mixing valve, flow valve, flow limiter jet regulator, water turbine with electric generator, water line sections, seals or the like waited without water leakage, in particular removed, ie removed, and replaced or repaired can. For this purpose, usually no below the sanitary body such as sink or the like arranged angle valve is necessary or this does not need to be additionally turned off or closed. Accordingly, this angle valve or upstream check valve when using the sanitary fitting according to the invention also completely or always omitted, which reduces costs and installation costs.

Preferably, the mounting lid is vandal-proof arranged or mounted on the fitting body. For this purpose, this can be installed inconspicuously in an advantageous manner. For example, the edge can be "hidden" or camouflaged as a design line so that inexperienced people do not realize that there is a separate lid here.

On the other hand, a special tool for removing or disassembling the mounting lid can be provided. Again, alternatively or in combination with the "camouflage" disassembly can be effectively prevented by vandalism.

Advantageously, the second actuator is arranged in the flow direction of the water flow in front of the first actuator. As a result, the first actuator or valve need not be actuated in order to expand or maintain any relevant components of the valve according to the invention.

Advantageously, the cross section of the housing opening is larger than a cross section of the first actuator and / or a dirt filter for filtering the water flow and / or at least one flow regulator for controlling the water flow rate and / or at least one electric generator driving a turbine for using the flow energy of the water flow. Hereby, the first actuator or the dirt filter or the Druchflussbegrenzer etc. are advantageously taken individually and / or together as a service or assembly on the free mounting opening of the fitting body out. A disassembly of the entire valve or the fitting body can be omitted. This is especially from the viewpoint of vandalism in the public or semi-public space especially for the maintenance / service or repair of great advantage. Not only hydraulic but also electrical components can be advantageously removed and reused according to the invention through the mounting opening.

Advantageously, the first actuator comprises at least one dirt filter for filtering the water flow and / or at least one flow regulator for controlling the water flow rate and / or at least one turbine driving an electric generator for utilizing the flow energy of the water flow. This ensures that the first actuator or flow valve is designed as a service or valve unit with essential hydraulic components and can be removed and re-installed in an advantageous manner from the fitting body. For example, for maintenance, service, repair and replacement. This improves the economic operation of the sanitary fitting according to the invention.

Preferably, at least one actuating unit is provided for actuating the second actuator. In a mechanical first actuator or Druchflussventil this can be designed as a rotary handle and / or lever and / or as the mounting lid.

In a particular embodiment of the invention, the actuating unit is designed as a fixing device for fixing and releasing the first actuator and / or the service unit. This ensures that already during disassembly or release of the first actuator or the service unit, the water pipe or the water flow is blocked or blocked. The same can also be realized with respect to the dirt filter and / or flow restrictor and / or the turbine and / or electric generator or the like. This means that even with the release / disassembly or separation of the first actuator and / or the service unit at the same time or directly coupled with each other, the hitherto opened second actuator / shut-off valve or the shut-off device is closed. Thus, the shut-off water pipe is cut at the same time. The same applies to the assembly process or the fixing of the first actuator / service unit and the thus coupled opening of the second actuator or the shut-off to.

Preferably, the blocking of the second actuator is at least partially by a rotational movement or a rotational path, in particular by rotation during release of the first actuator or the service or valve unit. For example, the fixing device is designed as a bayonet closure. Hereby, an advantageous shut-off and sealing of the water pipe or the water flow in the valve is achieved. The valve unit or the first actuator or the like is rotated, for example via a bayonet (eg 60 degrees), for example, counterclockwise and then the second actuator or service valve to and the first actuator or the whole valve unit with filter, flow regulator and solenoid valve, etc. can be removed. Installation is the reverse order.

Basically, the first and / or quite the second actuator can be formed as a purely mechanical shut-off valve with an actuating element which is designed as a rotary handle, lever or the like. Alternatively or in combination with this, an electrical and possibly additionally manually operable first actuator / valve can be provided, with which the water outlet is regulated. In an electrical operation, this can advantageously by means of a sensor, IR sensor or the like, and / or by means of an electrical switch as an actuator.

It is also conceivable to design the mounting lid as an actuating element of the second actuator or shut-off valve and / or to bring a locking unit into operative connection with the mounting lid, so that e.g. a mechanism actuates the second actuator. This ensures that the water flow is shut off or blocked during disassembly or opening of the mounting lid.

In an advantageous variant of the invention, the mounting cover comprises at least one actuating element for actuating, in particular, the first and / or possibly the second actuator. Hereby, the water outlet can be started and / or stopped manually by the user in an advantageous manner.

Advantageously, the mounting lid comprises at least one solar cell for solar power generation and / or a display unit for displaying parameters of the water flow and / or parameters of the control unit. Hereby, a largely energy-autonomous mode of operation and / or an advantageous display of essential parameters or information relating to the sanitary fitting according to the invention can be displayed to the user. For example, actual temperature of the water, set target temperature, fault yes / no or what component, automatic timer, set water drain time, energy reserve of the battery / battery or the like.

• Normale Waschtischarmaturen werden meist durch Schläuche oder Rohre an Eckventile angeschlossen. Die Eckventile dienen dazu, die Wasserversorgung zu unterbrechen, wenn an der Armatur Reparatur- oder Wartungsarbeiten durchgeführt werden müssen. Solche Wartungsarbeiten bestehen z.B. darin, dass die Schmutzsiebe gereinigt oder ausgetauscht werden müssen. Häufig sind die Eckventile nur schlecht zugänglich - unterhalb des Waschbeckens und oftmals besonders schwierig durch Verbauten unterhalb der Waschbecken

Particular advantages of the invention:

• Normal washbasin faucets are usually connected by hoses or pipes to angle valves. The angle valves serve to interrupt the water supply when repair or maintenance work has to be carried out on the valve. Such maintenance consists, for example, in that the dirt strainers must be cleaned or replaced. Often, the angle valves are poorly accessible - below the sink and often particularly difficult by installing below the sink

According to the invention is achieved, the maintenance and repair work very easy and easy to access. The invention makes it possible to perform all work on all hydraulic components "above the sink" without dismantling the valve and without operating any shut-off devices for the water supply.

By removing the service unit, the water supply (within the fitting body) is automatically interrupted / shut off. Thus, all maintenance can be made easily and easily. When re-inserting the integrated shut-off valve is opened again and the valve is ready for use.
