Description

Switching device, especially for outlet fittings

description

The invention relates to a switching device, in particular for outlet fittings according to the preamble of claim 1.

The saving of water is becoming increasingly important due to environmental protection efforts and the constant increase in costs for fresh water supply and wastewater disposal, also for areas of application that were previously considered inaccessible for saving measures. A waste of fresh water e.g. washing hands or doing something at a sink in the kitchen is very easy, since doing things e.g. Running water is only required for a wash basin for a small part of the period of use. For example, when washing hands, it is sufficient to briefly operate the outlet fitting at the beginning and before soaping the hands. After that, water is generally no longer required until the hands are removed from the soap to be removed. Usually, however, for thoughtlessness or convenience, the outlet fitting is left in the switch-on position during the entire washing time, as a result of which large quantities of fresh water flow into the sewage system in a useless and costly manner. The outlet fitting is often not actuated to switch off the water flow because one of the functions, for example, there is no hand free in the kitchen to operate the spout.

An attempt was therefore made to release water from an outlet fitting only with the aid of automatically switching valves when water was actually required. Devices of this type are known, for example, from public toilets or the like. Various technical implementations have been proposed for this purpose, whereby the presence of objects or persons, for example the hands to be washed, in the area below a discharge fitting or the like is always used as a criterion for a need for water. For this - 2 -

As a rule, sensors are arranged at a short distance from the outlet fitting, which monitor the area directly below the outlet fitting and always switch the outlet fitting into the open position when an object is detected. Both infrared and radar sensors, which usually operate in the form of a light barrier, can be used as detection sensors. The problem with this is that in order to avoid constantly switching the valve on and off, a certain inertia of the control of the water flow is required, for which purpose an adjustable run-on time is usually provided after the last detection of an object or a person. This, however, has a short-term influence on the water outlet through actions by the user, e.g. Removing the hands from the detection area is impossible. The water savings achieved are therefore far below an actually achievable value. Such controls are known both on hand basins and on toilets or urinals. Providing such a rather expensive facility is generally only worthwhile for public or semi-public toilet facilities, and in particular retrofitting to existing facilities is only problematic and costly.

A similar application situation exists if, for example, in hospitals, doctor's practices or the like. During sterilization, for example of the hands, for hygienic reasons, the outlet fitting may no longer come into contact with the freshly washed hands in order not to start cleaning again to have to. For this purpose, devices, for example the AQUA self-closing knee valve DN 15 from Aqua-Butzke, are known which, in cooperation with spout armatu ren, allow actuation of the open position of the spout fitting with the knee. For this purpose, mechanical lever arrangements are attached to a fitting such that the actuation of the lever mechanically changes the open position of the outlet fitting or the outlet armatu r switches between an open and a closed position. Such devices are expensive and only very complex to assemble, they also require a large installation space below the washbasin and must be securely attached because of the large lever dimensions. Also, the lever has to be kept pressed partially to actuate, so that the longer running of water is ergonomically poor. - 3 -

Furthermore, electrically operating switching devices are known which, for example, by means of an electrically operated foot switch Enable the water flow of an outlet fitting to be switched on and off in the base area of a base cabinet or in the floor area. Devices of this type are just as unfavorable to operate as the mechanically operated variants, since they either only have actuating elements arranged in an ergonomically disadvantageous manner or require the actuating foot to remain in an ergonomically unfavorable position.

The object of the present invention is therefore to propose a switching device, in particular for outlet fittings, which gives the user a great deal of freedom in the choice and setting of the flow rate of the outlet fitting and which is convenient and safe to use.

The achievement of the object according to the invention results from the characterizing features of claim 1 in cooperation with the features of the preamble. Further advantageous embodiments of the invention result from the subclaims.

The invention is based on a switching device, in particular for outlet fittings, comprising a switchable valve and an actuating device, the actuating device being able to change the opening position of the switchable valve and thus the water flow through the outlet armatu r, and the actuating device, in particular, also being operable without the aid of the hands is. Such a generic switching device is further developed in that the actuating device is mounted in the area of a device arranged near the outlet fitting in such a way that it can be actuated by changing the position of at least one triggering part of the device. This makes it possible to no longer operate the outlet fitting with a switching element located at a precisely defined and possibly ergonomically unfavorable location, but rather with a part of a piece of furniture in the vicinity of the outlet fitting, for example, with a relatively large area. Influencing the water flow through the outlet fitting can therefore be carried out very conveniently, which means that the incentive to switch off quickly and to switch on the water flow only when required enables high water savings. Is also through - 4 -

the possibility of actuation without the help of the hands ensures that when performing operations on or under the spout armatu r both hands are available, which particularly increases the ease of use of the spout fitting.

The use of the switching device according to the invention is particularly advantageous if the item of furniture is a base cabinet, a washstand, bathroom furniture or the like and the triggering part of the item of equipment which actuates the actuating device is a door, a flap or the like. Such furnishings are widely available, especially in private households in the vicinity of spout armatu. However, it goes without saying that the areas of application of the switching device according to the invention can be designed in a variety of ways, that is to say it is useful and possible to use the switching device wherever a lot of constantly adapting amounts of water are used. In addition to the area in the household or bathroom of private individuals, this is in particular also the commercial area, for example in canteen kitchens, laundries, industrial productions or the like encompassed by the invention. Of course, the invention encompasses the fact that, in addition to furnishings already present at the outlet of the water, the switching device according to the invention can also be modified by actuating large-scale triggering parts of the furnishings so that the furnishings are provided entirely or almost exclusively for actuating the water flow. So it does not have to be a piece of furniture in the sense that is limited to furniture or the like. It also does not have to be a piece of furniture designed the size of a base cabinet or the like, but it can also be a special switching element which is of relatively large area and which is arranged relative to the user and sink or the like. If the item of furniture and triggering part is always referred to below, this also always means an embodiment of the invention explained above. The application is also not limited to the use on water-bearing fittings; rather, other substances, for example other fluids or powdery substances, can also be used with the switching device according to the invention - 5 -

or otherwise flowable substances through suitable outlet fittings with the switching device according to the invention e.g. be divided.

A particularly advantageous embodiment of the switching device according to the invention is obtained if the actuating device is mounted inside or on a piece of furniture preferably arranged under the outlet fitting such that a change in the position of the triggering part of the piece of furniture actuates the actuating device with a knee or other parts of the lower body. For explanation, reference is made to an area of application in the household. Base cabinets usually provided as standard elements in the kitchen area or vanities or bathroom furniture provided in the bathroom area can be such furnishings and normally have doors, flaps or the like accessible from the front of the washbasin or the like, which can serve as release parts and below and a little are arranged behind the sink or the like. This makes it possible to stand directly on the sink or the like. Here, the door, flap or the like is often arranged so that the user e.g. with his legs, knees or other parts of the lower body leaning against this door, flap or the like. This assignment of the lower body or parts of the lower body of a user relative to the base cabinet, washstand, bathroom furniture or the like is now used to change an actuating device arranged in or on the furnishing item by changing the position of the door, flap or the like of the furnishing item to operate, which in turn influences the water flow through the outlet armatu r by means of electrical signals. This enables the user of the wash basin or the like to influence the water flow without looking closely or palpating an actuating device that can only be operated locally, e.g. So switch on or off or change the flow rate. For example, a slight pressure on the door, flap or the like is sufficient to actuate the actuating device and to switch the water flow on or off.

The circuit of the actuating device can be particularly easily attached to a device, preferably at knee height, or in a piece of furniture - 6 -

Make the switching element, since the switching element is then actuated directly at the location of the force introduction into the triggering part. For this purpose, the knee height is appropriate, since the knee is the easiest part of the lower body to change its position and usually relieves one leg when standing in front of a sink or the like and thus one knee is free for horizontal movements.

It is particularly convenient to actuate the outlet fitting if the actuating device has a button as the switching element. Such a button can only release the water flow through the spout armatu r only in the pressed state, whereby the water flow is interrupted in the form of a dead man's switch when the button is relieved. Due to the ergonomically favorable operation e.g. by means of a trigger part in the form of a door, flap or the like. For example, the user can also lean comfortably against the trigger part even if the water flow is required for a longer period of time without being tired by the continuous actuation.

It is also conceivable that the actuating device has a switch as a switching element which can be switched between two switching positions. As a result, further relief for the user is possible, in particular in areas of application in which a large amount of water frequently has to leak.

The switching device can be implemented in a particularly cost-effective and simple manner if the switching device has an electrically switchable magnetic self-closing valve as the switchable valve. Such valves are commercially available and are therefore relatively inexpensive and safe to use. In addition, it is ensured in the event of a power failure that the magnetic self-closing valve changes to the closed switching state and thus an unintended water flow is prevented.

Furthermore, a permanent switch for switching the switchable valve into a permanent opening position can be provided on the actuating device. Such a permanent switch can be used, for example, to ensure continuous operation of the outlet fitting even with larger quantities of water required, independently of the actuating device, for example by means of the shut-off device normally provided on the outlet fitting as with a - 7 -

Single-lever fitting or the like. This bridges the function of the actuating device and the outlet fitting can be operated in the way that would be possible without the switching device according to the invention.

It may also be possible to provide an external permanent switch which is arranged at a distance from the switching device and by means of which the switchable valve can be switched into a permanent open position. This is useful, for example, if you do not want to bend down under the sink or the like to switch over to the normal operation of the outlet fitting, in order to switch over using e.g. an integrated permanent switch. Such an external permanent switch can, for example, be used for remote switching in a flush-mounted box arranged above the wash basin or the like or also at a further distance from the wash basin or the like.

With regard to the emergency operating properties, it is advantageous if a bypass valve is provided which allows water to flow through the switchable valve in the event of a power failure. For this purpose, for example, a manually switchable bypass valve between the inlet and outlet of the water circuit is provided on the switching device, which shorts the water flow through the switchable valve by switching in the event of a power failure and thus ensures the normal function of the outlet armatu r even without the switching device according to the invention.

It is conceivable to change the flow of cold water and / or hot water of the outlet armatu r with the switching device. Here, the switching device can be provided either only for the cold water circuit or only for the hot water circuit of the outlet fitting, both circuits can also be operated simultaneously. In the latter case, the temperature of the escaping water is usually manually adjusted once at the outlet fitting by the mixing ratio of hot and cold water.

If both cold water and hot water are switched separately, separate actuating devices and / or separate switching elements can be connected to an actuating device for cold water and hot water on the switching device. - 8th -

water can be provided. This makes it possible to influence the water flow in a targeted manner, it also being possible to regulate the water temperature directly by means of such a separate actuating device. It is particularly advantageous if, in a further development, the separate actuating devices for cold water and hot water from at least two different triggering parts, e.g. Flaps, doors or the like. The furnishings are actuated. As a result, hot water can be mixed in, for example, by actuating one trigger part with one knee and by actuating the other trigger part with the other knee.

In a particularly advantageous embodiment, all parts of the switching device, such as the actuating device, magnetic self-closing valve and further auxiliary devices, can be arranged in a common housing. Such a compact unit is attached, for example, to or near the trigger part such as a door, flap or the like in the wash basin or the like in such a way that the switching element is actuated by the trigger part such as the door, flap or the like. For this purpose, it is advantageous if connection devices for the water circuit to be switched are provided on the housing, with which, for example, the hot and / or cold water inlets are led to the switchable valve arranged in the common housing or to a plurality of switchable valves. Commercial connection devices such as Compression fittings or the like can be used.

It is also conceivable that water-side valves and connection devices and electrical switching devices are separated from one another, preferably in separate and / or separately arranged housings. This makes it possible to arrange the electrical and the water-side parts of the switching device at a distance from one another. As a result, in addition to the increased security against electric shock, a simpler installation and connection to the on-site facilities can also be realized. It is particularly advantageous if the water-side valves and connection devices are arranged directly in or on the on-site pipeline. Another advantageous embodiment can be achieved if the water-side valves and connection devices are directly in - 9 -

or at the on-site installation of a corner valve, preferably integrated in the corner valve. In particular, this makes it possible to form a compact water-side unit which can be easily installed instead of a conventional corner valve and only preferably still has to be electrically connected to the actuating device arranged in the vicinity of the trigger part such as a door or flap or the like.

In order to ensure a faultless switching function of the actuating device, it is necessary that the setting of the actuating device for the interaction with the triggering part such as a door, flap or the like of the device object can be carried out by adjusting devices on the housing of the actuating device. As a result, the assignment between the switching element and the triggering part is set, whereby a reliable switching of the switching device is achieved even with small changes in the position of the triggering part. An adjustment can be made, for example, in the usual way in the case of hinges, through elongated holes or the like, which enable the switching device to be displaced and adjusted relative to the triggering part.

In one configuration, the setting of the actuating device for the interaction with the triggering part of the furnishing can be undertaken by adjusting devices on the switching element of the actuating device. For example, the installation situation of the switching element can be changed in a finely adjustable manner relative to the housing of the switching device by using an adjusting screw or the like.

In another embodiment, the switching element can be relieved of the pressure of the release part such as a door, flap or the like in the closed state by resilient elements on the actuating device in a closed position of the door, the flap or the like. In a preferred embodiment, the actuating device can have, as a resilient element, at least one adjustable spring pin which presses against the release part and at least partially relieves the switching element of the closing pressure of the release part. It is also conceivable that the actuating device as the resilient element has permanently elastic or resilient material in the vicinity of the switching element, which is so arranged. - 10 -

net is that in the normally closed state of the trigger part such as the door, flap or the like. The switching state of the switching element is not actuated and a remaining switching path is still available.

It is particularly advantageous if the actuating device has a circuit logic with which the water flow of the outlet armature can be switched on or off by briefly pressing a switching element once or several times. With such a circuit logic, switching of hot and cold water can be implemented, for example, in coded form by only one switching element, in that the signal sequence or the like entered in accordance with the coding contains information about the water circuit to be switched. For example, a simple brief actuation of the switching element can turn on the hot water, a double short actuation of the switching element can turn on the cold water and a single long actuation of the switching element can turn off hot and / or cold water. For this purpose, various combinations of coding and switching actions are conceivable, which of course are also included in the invention. It is also conceivable that the actuating device has a circuit logic with which a switching between cold water and hot water can be carried out directly by actuating a switching element.

In a particularly advantageous development, the actuating device can also have a circuit logic with which the flow rate of the outlet armatu r can be changed by actuating a switching element for different lengths. Such circuit logic, which operates like an electric dimmer, can ensure, by actuating it for different lengths, that the flow rate of the outlet fitting is changed, for example increased or decreased. For this purpose, a number of circuit and coding variants are known from electrical circuit technology, which can be transferred in particular to the application at hand here if the circuit logic of the actuating device corresponds to that of a commercially available electronic dimmer, and thus possibly even has a commercially available electrical dimmer which controls an electrically switching valve. - 1 1 -

It goes without saying that, in addition to solenoid self-closing valves with a purely open / close function, valves which enable a controlled change in the flow rate can also be used in the configurations with a circuit logic.

Furthermore, it goes without saying that in addition to the electrical switching of the switchable valve, other transmissions of the desired signal state from the actuating device to the switchable valve are also covered by the invention. A transmission can take place, for example, with suitable modification of the switching device by pneumatics, hydraulics or the like.

The drawing shows a particularly preferred embodiment of the switching device according to the invention.

Different variants of the switching device according to the invention are shown in FIGS. 1 to 4, with the same part numbers denoting the same parts of the switching device. Reference is therefore made to all figures in the description. - 12 -

FIG. 1 shows an application example of the switching device according to the invention on a sink 5 with an armatu r 3 outlet, for example in a kitchen of a private household. A typical installation and application situation can be seen, in which the switching device, consisting of an actuating device 10 integrated into a housing 20, 24, is arranged below a wash basin 5 with an outlet fitting 3. The actuating device 10 is in this case installed in a piece of furniture 6 designed as a sink base cabinet and interacts with a release part 2 of the furniture item 6 in the form of the front door of the base cabinet in a manner which is shown in more detail below.

The actuating device 10 is connected on the water side between the water inlet through a corner valve 7 provided on site with a water inlet 8 to the water supply. The water inlet 8 leads to a connection element 23 designed, for example, as a compression fitting, a switchable valve 16 being arranged between the connection element 23 for the water inlet 8 and a corresponding connection element 22 for the line 9 to the outlet fitting 3, not visible in FIGS is and interrupts or releases the water flow depending on the switching state of the switching device.

On the front side and actuable by the trigger part 2 designed as a door there is a switching element 12 that is arranged, for example in the form of a button or switch, on the piece of furniture 6 in such a way that the trigger part 2 designed as a door rests on the switching element 12 in the closed state of the door, which But switching element 12 just does not trigger. For this purpose, the actuating device 10 can be adjusted relative to the closed position of the trigger part 2, for example with the aid of adjusting devices 19 designed as elongated holes, in that the optimal switching point is adjusted by small displacements relative to the closed door. It is also conceivable, for example, to make the switching element 12 adjustable relative to the housing 20 by means of an adjusting screw.

As an additional device, a permanent switch 13, which passes through the housing cover 24 on the outside, is provided, with the aid of which the switchable valve 16, which is designed, for example, as a magnetic self-closing valve, is switched into the open position. - 13 -

can be brought and whereby the effect of the actuator 10 can be overridden.

Only shown in FIG. 2 is a further permanent switch 15 which can be attached externally and is connected in parallel with the internal permanent switch 13 and which can be arranged, for example, above the basin 5 within easy reach.

In addition, the actuating device 10 has a bypass switch 11, which is arranged on a non-visible, advantageously purely mechanically switchable bypass valve and can also be changed over manually in the event of a power failure. In the event of a power failure of the supply voltage 18, commercially available magnetic self-closing valves 16 change to the closed state for safety reasons and, in the event of a power failure, no water leakage through the outlet fitting 3 would be possible. The bypass valve with the bypass switch 11 arranged thereon is looped in parallel to the switchable valve 16 and forms a short circuit when manually switched, through which the water can then flow from the corner valve 7 to the outlet fitting 3.

On the housing 20 there is also a cable bushing 21 for introducing the cable of the power supply 18, which either introduces a low voltage provided outside the switching device into the actuating device 10, or a voltage converter (not shown) is provided in the actuating device 10. The housing cover 24 closes the housing 20 of the actuating device 10.

The function of the switching device can be described as follows.

The actuating device 10 is connected between the water supply at the corner valve 7 and the outlet armatu r 3, that by actuating either the permanent switch 13, 15 or the switching element 12, for example, designed as a button, the switchable valve 16 by the actuating device 17 from the closed to the open Position is switched. This clears the way for the water and can reach the outlet fitting 3. The switching element 12 is actuated by, for example, a door of a base cabinet. - 14 -

Formed trigger part 2. The trigger part 2 is actuated by the user 1 by means of a knee 4 or by leaning against the trigger part 2, which is designed as a door, the trigger part 2 shifting slightly in its position relative to the piece of furniture 6 designed as a base cabinet. In this case, the trigger part 2 is positioned in its non-actuated rest position relative to the switching element 12 in such a way that the switching element 12 has not yet been actuated. By actuating the knee 4 or leaning the user against the item of furniture 6, the trigger part 2 moves slightly with respect to the item of furniture 6, the switching point of the switching element 12 is reached and exceeded and the switchable valve 16 is opened electrically by the switching element 12 . If the switching element 12 is a button, the switchable valve 16 remains open as long as the button is actuated. If the switching element 12 is designed as a switch, actuating the trigger part 2 switches the switching state of the switching element 12 and the switchable valve 16 remains open until the switch is actuated and switched again by the trigger part 2.

Thus, the user 1 can perform e.g. with his knee 4, who also completely leave his hands free for performing operations on the basin 5 or on the outlet fitting 3, release the water flow at the outlet fitting 3.

It goes without saying for a person skilled in the art that in addition to the embodiment explained here, a large number of modifications in the design of the switching device and the possible areas of application are conceivable and are encompassed by the invention.
