Definitions

  • the invention relates to a method for contactless actuation of the water flow in a sanitary facility, with an electronic control device, a touch device with a radiation source and an optical sensor, and a valve arranged in a water supply.
  • the invention also relates to an arrangement for contactless actuation of the water flow of a sanitary facility, in particular a wash basin fitting, with an electronic control device, a touch device with a radiation source and an optical sensor, and a valve arranged in a water supply.
  • the arrangement according to the above-mentioned Swiss patent application has an infrared light pulse transmitter, an infrared receiver with a threshold value amplifier and an electronic control device.
  • the radiation power of the infrared light pulse transmitter can be varied by means of the control device.
  • the detection performance is continuously tracked against the background or a changing object, so that objects located in the detection zone can be identified as stationary or moving objects.
  • Other contactless actuations in particular for wash basin fittings, are also known in the prior art. These contactless actuations have the advantage that they are more hygienic than conventional actuations and generally contribute to reducing water consumption.
  • the inventor has now set himself the task of creating a method and an arrangement of the type mentioned which facilitate cleaning of the sanitary facility.
  • the method or the arrangement is intended to enable or facilitate the cleaning of a washbasin.
  • the usual use of the sanitary facility should not be hindered in any way.
  • the object is achieved in the above-mentioned method in that when the touch device is covered, for example with one hand, the control device keeps the valve in its current state. This makes it possible for a cleaning person to "freeze" the desired state by simply covering the touch device.
  • the arrangement according to the invention is characterized in that the pushbutton device is designed such that when it is covered, for example with one hand, it reflects scanning pulses with a comparatively high light output and the control device keeps the valve in the current state on the basis of these scanning pulses.
  • the method according to the invention can be implemented by appropriate programming of the control device, so that there are no additional costs and it is also possible to change or remove the cleaning function with little effort.
  • the arrangement has a scanning device which has a radiation source and an optical sensor in a concentric arrangement, as disclosed in the above-mentioned Swiss patent application. If the scanning device is covered with the hand or a finger, this results in an unusually high reflected light output of the scanning pulses, which the control device identifies as "covering the optics". If the control device has identified such a cover, then it keeps the valve in its current state. This state is preferably limited in time, for example for a duration of 60 seconds. If the valve is thus open before the cover, it remains open even when the pushbutton device is covered. Otherwise the valve remains closed.
  • the control device automatically switches to a so-called “sleep mode” in order to prevent the battery from being quickly and prematurely discharged by permanently covering the touch device, for example by means of an adhesive strip or the like.
  • the cleaning person approaches the sink and covers the touch device with his hand or a finger. With her free hand she cleans the wash basin, whereby the water flow of the tap is not disturbed, since the control device keeps the valve in the current state. If the cleaning person needs some water, a hand movement with the hand covering the touch device is sufficient. As soon as the water turns off, it can "freeze” the idle state again by covering the touch device again.
  • the cleaning person To flush away a cleaning agent in the sink, the cleaning person briefly moves the hand covering the touch device away from the touch device and, as soon as water flows out of the tap, keeps the water flow by covering the touch device. With her free hand she now wipes away the cleaning agent while the water is running, without the water flow being accidentally interrupted. By removing the hand covering the sensing device, the water is turned off after the usual delay of, for example, 2 seconds.
  • the cleaning person In turn covers the touch device when the tap is turned off. Now that no water flows during the cover, the cleaning person can rub the washbasin dry unhindered.
  • the basin can thus be cleaned just as quickly and thoroughly in the case of a basin fitting as in the case of a conventional fitting. Since the cleaning function can be implemented by programming the control device, it can be implemented very inexpensively and can also be changed or canceled. In addition to a wash basin fitting, application of the invention is also advantageous in other sanitary devices with contactless actuation, for example in a urinal.
