Definitions

  • the present invention relates to a device for the electrical triggering of a water discharge with an actuator plate and a sensor, wherein the sensor is arranged in the back of a triggering user from the triggering water user behind the actuating plate.
  • the EP 1 961 876 describes a device for the electrical release of a toilet flush, wherein the actuator plate is a glass plate or a plate made of a non-conductive material.
  • the sensor keys are capacitive sensors that contact the approach of one or more fingers or the hand of a user from the opposite side of the actuator plate without contact.
  • the actuator plate is therefore a plate made of an electrically non-conductive material, in particular a glass plate.
  • the sensors of the capacitive sensor keys are glued to the back of the actuator plate. On the front of the actuator plate actuation symbols are applied, for example printed, in front of the area of the sensor keys.
  • the flush plate can be installed without joints in the front of a toilet flush, so that their cleaning can be easily accomplished.
  • a glass ceramic plate which should have a viewing window.
  • This viewing window is achieved by virtue of the fact that the ceramic plate, which is actually open to view, has received an opaque coating from the rear side, which is recessed only in the desired viewing window.
  • a capacitive sensor is also provided, with which the function of the heating plate can be triggered.
  • a light source is provided behind the glass ceramic plate in the viewing window area in order to provide feedback to the user can.
  • there is a precious metal coating which, on the one hand, supports the technical function of optimizing the activation of the capacitive sensor and, on the other hand, is partially reflective.
  • the transmission is in the range between 1 and 20%, so that the light source can be seen.
  • a flush valve with the features of the preamble of claim 1 and with a viewing window behind which viewing window a working on light reflection base proximity sensor is provided with which the valve is triggered.
  • the infrared sensor also referred to as IR sensor for short, on the one hand should be able to detect the approach of a user to the flush valve and on the other hand the sensor is able to distinguish when the valve is to be triggered by the user "pressing" corresponding tactile areas.
  • the triggering is ensured by an infrared distance measurement.
  • an optical illuminant is provided behind the viewing window, with the user of the valve, the operating state or the triggered or triggered function is displayed.
  • the present invention seeks to provide an improved device for the electrical triggering of a water discharge, in particular for a Spülarmatur, the better function at high optical standard and easier and less conspicuous user guidance guaranteed.
  • the actuating plate is divided into areas which are coated differently from the side facing away from the user.
  • the actuator plate is provided with a partially transparent coating, so that without the illumination of the display symbols and operation symbols, the plate appears opaque, while lighting the display symbols and operating symbols for the Users are clearly recognizable.
  • a coating which is opaque to human visible light and which is transparent to infrared wavelengths.
  • the light transmittance for infrared can be selected depending on the IR light source used.
  • actuator plate for IR light sources and IR sensors are provided, so that the possibly reflected by a user of the fitting and scattered IR light is collected and detected only by one of the sensors and so between approach detection and actuator recognition can be distinguished.
  • the infrared light of the light source is detectable by the IR sensor when a user is in an approach area in front of the operation plate, it means that a threshold set by a circuit or settable / adjustable threshold is exceeded upon approach of a user, so that the corresponding response signal of the sensor for the circuit is detected.
  • two IR sensors are used, a first sensor for remote detection of the approach of a user to the valve (which, for example, after a certain time trigger a forced flush) and a second sensor (and / or third sensor) for the Close recognition of the user, for example, if he wants to select the small flush or a large flush in a toilet system.
  • the corresponding signal values are used by appropriate evaluation of the reflected light components.
  • two or more sensors can be used for the remote detection and / or for the proximity detection in order to be able to adapt the sensitivity of the sensors to the respective situation.
  • Another sensor can be used to detect the position of the user, for example by triangulation.
  • several IR light sources can be used; for example, one behind the display area of the large flush and one behind the display area of the small flush with a single IR sensor midway between them; then alternately radiate the two IR light sources and thus intermittently a signal from the single sensor will be detected. If then a user's hand is moved in front of one of the display areas, then this signal will fail and the circuit behind it recognizes that a triggering is to be effected.
  • a broadband or combined IR light source wherein the two different remote and near sensors are sensitive to other IR wavelength ranges.
  • Two light sources operating in different IR wavelength ranges can also be detected with two sensors that are either inherently sensitive to these different IR wavelength ranges, or those behind correspondingly coated areas of the actuator plate are provided.
  • a temporal discrimination of the emitted and detected signals can be made so that they can be generated without problems by IR light sources of the same wavelength range.
  • the actuator plate has opaque and partially transparent (IR or visible light) areas. The user takes the actuator plate but as a homogeneous surface was and is aware only by the indicator light sources of a function.
  • the drawing shows a schematic exploded front view of a control panel with light sources and light sensors arranged behind and an optional mounting frame.

  • Individual coated areas of the sensor areas 31, 32, 33 and the opaque areas 9 etc. may have a size of 15 by 30 millimeters, while the display areas 22 and 23 are, for example, 60 by 90 millimeters.
  • This control panel 1 is made of a transparent material, in particular and for example made of glass. It can also be Plexiglas, tempered glass or safety glass.
  • the feature transparent to the material means that the plate 1 is transparent to the wavelength ranges of visible light and infrared light.
  • visible light for a human user means visible light, in particular light in the wavelength range between 380 and 780 nanometers
  • infrared light for a human user generally non-detectable light in the infrared wavelength range, in particular light in the wavelength range between 780 nanometers and 3 microns, the like called near infrared, in particular, a wavelength range between 780 nanometers and 1 micrometer is used.
  • the actuator plate 1 can also be translucent, with a dispersion of less than 5% for a clear display of the light elements and a directed passage of the infrared sensor radiation is advantageous.

  • the coated area 22 is spatially larger than the area designated as a trigger area 42, so that the light of the display light source 10 can be seen from different angles in its passage through the actuator plate 1 by the user.

  • opaque coating areas 9 and only visible light transmissive areas 22 and 23 may be arranged, since the sensor light source 20 must radiate only through the area 21 in an angled cone, which allows one in a certain distance and area before the actuator plate 1 standing user or a user's hand generates a reflected and / or diffused signal, which falls back in the direction of the actuator plate 1 and falls through the window 52 to the sensor 32.
  • the area 52 of the actuating plate in front of the infrared sensor 32 is now covered on the back with a coating which transmits the light of the infrared sensor light source 20, preferably a narrow wavelength range around this infrared light wavelength only.
