Definitions

  • the invention relates to a control device for a sanitary fitting, in particular a water outlet control, with a detection device containing at least one transmitter and a receiver, preferably working with infrared light radiation, control and evaluation electronics and one or more batteries or accumulators for the electrical energy supply.
  • a control device for a sanitary fitting, in particular a water outlet control, with a detection device containing at least one transmitter and a receiver, preferably working with infrared light radiation, control and evaluation electronics and one or more batteries or accumulators for the electrical energy supply.
  • control devices are mostly used for water outlet fittings on washstands, urinals etc.
  • One or more primary cells with a defined minimum capacity and a limited, also system-related shelf life are used for energy supply in these battery-operated, non-contact controlled sanitary fittings.
  • the invention has for its object to provide an improved control device in which the consumption of electrical energy can be significantly reduced. It is part of the task to propose a simple and safe method for installing and operating the control device in a sanitary fitting.
  • a solenoid valve 4 with a water inlet 41 and a water outlet 42 is provided.
  • the solenoid valve 4 can be controlled by control and evaluation electronics 1.
  • a detection device 2 is provided in the area of the water outlet 42, with which the presence of a user can be determined.
  • a transmitter 21 emits a clocked infrared light beam, which is reflected by a receiver 22 after being reflected on an object in the predetermined detection range.
  • the detection device When the presence of a user is ascertained, the detection device generates a signal which is output to the control and evaluation electronics 1, in which a corresponding water outlet program is then processed via a microprocessor or microcontroller, the magnetic valve 4 in the water outlet fitting being after a predetermined period of time ( Delay time) an opening pulse and a closing pulse is supplied after a likewise predetermined opening period.
  • the electrical power supply to the control and evaluation electronics 1 with the detection device 2 and the solenoid valve 4 is provided by a battery 3, the control and evaluation electronics 1, the detection device 2, which Battery 3 and the solenoid valve 4 are integrated in the water outlet fitting.
  • the system software of the control and evaluation electronics 1 is expanded with an energy-saving mode in which the program execution normally executed is interrupted and all peripheral consumers, in particular the particularly energy-intensive transmission of infrared light , with the exception of the receiver 22 for infrared light radiation, the sensitivity of which is advantageously increased by appropriate circuitry.
  • the software for the energy-saving mode (sleep mode) is stored in a module 11.
  • the microcontroller unit or microprocessor unit provided in the control and evaluation electronics 1 is itself switched to a stand-by mode (STOP mode, POWER DOWN mode), which reduces the current consumption, for example, to 0.3 to 1.0 microamps or approximately minimized one hundredth of the current consumption in normal operation.
  • STOP mode POWER DOWN mode
  • the output signal of the receiver 22 is connected directly or via a suitable amplifier / filter circuit to an input (interrupt input) of the control and evaluation electronics 1.
  • the energy saving mode (sleep mode) of the water outlet fitting is preset by the manufacturer using a suitable tool, e.g. programming device, remote control, etc.
  • the module 11 is present in the software of the control and evaluation electronics 1 or of the microcontroller, which is activated by the mentioned aids, after a defined delay time of, for example, 60 seconds Targeted "powerdown" of the control and evaluation electronics 1 or the microcontroller in "sleep mode" is carried out.
  • the control and evaluation electronics 1 or the controller then ceases all activities, except for monitoring the interrupt input (microcontroller port) of the receiver 22.
  • a sticker 23 is issued during the delay time infrared-opaque material on the detection device 2, in particular on the receiver 22 attached.
  • the normal mode of the control and evaluation electronics 1 is reactivated by the detector 22 detecting infrared light radiation that exceeds a limit level value, as a result of which an interrupt is triggered at the microcontroller port.
  • the control and evaluation electronics 1 can therefore be switched from the energy-saving mode to the normal operating mode by removing the sticker 23, i.e. Sending infrared light pulses and presence detection with appropriate circuits of the solenoid valve 4.
  • the increased sensitivity of the receiver is advantageous in that the infrared light background radiation contained in normal daylight is sufficient in terms of intensity to switch from the energy-saving mode to the normal operating mode.
  • the activation of the normal operating mode can be triggered by any type of infrared light radiation with a relevant wavelength range, such as incandescent light, candle light or by rubbing a match, etc.
  • the control and evaluation electronics 1 can be in the following To be installed and operated in a sanitary fitting: At the factory, the solenoid valve 4, the detection device 2, the control and evaluation electronics 1 and the battery 3 are first installed in a sanitary fitting housing provided with a water inlet 41 and a water outlet 42 during the final assembly. The sanitary fitting is then subjected to a final test.
  • the energy-saving mode (sleep mode) in the control and evaluation electronics 1 is first activated with a hand-held transmitter (IR remote control), the receiver 22 then being present in a predetermined, but in principle freely selectable delay time of, for example, 60 seconds the sticker 23 made of infrared-opaque material can be covered and / or the fitting can be packaged in a packaging made of infrared-opaque material, after which storage and / or transportation with distribution of the sanitary fitting can follow over a relatively long period of time.
  • IR remote control IR remote control
  • the packaging and / or the sticker 23 are removed from the detection device 2, so that now when the receiver 22 detects a sufficient infrared light level (intensity) (via microcontroller interrupt), the energy-saving mode (sleep mode) the control and evaluation electronics 1 is deactivated and the normal operating mode is activated.
  • the sanitary fitting is now ready for normal operation.
  • the installer / user therefore requires no or only generally available aids to activate an automatic sanitary fitting delivered in energy-saving mode (sleep mode) or to switch it to normal operating mode.
  • a once activated energy-saving mode (sleep mode) is also taken up again after removal and reinsertion of the battery 3 after an activation delay has expired.
  • a "POWER ON RESET" of the control and evaluation electronics 1 leads the device back into the energy-saving mode (sleep mode), as long as a microcontroller interrupt is not triggered by the reception of an adequate infrared light intensity.
  • the energy saving mode can be activated and deactivated as often as required. This makes it possible to demonstrate the function for training courses, exhibitions, etc.
  • the subsequent activation of the energy-saving mode (sleep mode) can be useful if the capacity of the installed battery is to be spared for the period of prolonged non-use of the valve.
  • control and evaluation electronics can also be designed such that, for example, level-selective by evaluating the intensity of the received signal, which is caused by reflection of the infrared light transmission signal on a reflector, as described, for example, in German patent application P 44 20 335.7 is specified, is received by the receiver 22, the activation of the energy saving mode takes place.
  • the control and evaluation electronics according to the invention can also provide for the activation of the energy-saving mode when the infrared light intensity in the receiver caused by the transmission signal exceeds a defined level for a certain period of time t.
  • control and evaluation electronics can be designed in such a way that it provides for an automatic activation or deactivation of the energy-saving mode even by evaluating the current ambient infrared light radiation. Monitoring of the infrared light surrounding radiation can thus be used to identify phases of non-use, such as night operation or darkness, etc., with automatic activation of the energy-saving mode or a reactivation of the normal operating mode.
