Definitions

  • the invention relates to an actuating device for fittings, in particular for sanitary fittings, with at least one input unit which has a plurality of sensors which are connected to a control unit, and at least one drive unit for at least one closure device for at least one fluid line, in particular for a valve of a water pipe , which is controllable with the control unit, wherein at least three sensors are arranged substantially uniformly distributed substantially along a closed curve.
  • the invention relates to a method for operating an actuating device for fittings, in particular for sanitary fittings, in which depending on sensor signals at least one drive unit for a closure device of a fluid line, in particular for a valve of a water pipe, is controlled.
  • Actuators of the type mentioned above are used in particular for setting a water temperature and / or a water volume flow in sanitary facilities.
  • the DE 29505470 U1 Proposes to perform a simultaneous analogue adjustment of flow rate and temperature by a single operation of a pressure point within an analog control panel with area X - Y arrangement. If a wrong pressure point is inadvertently actuated here, this can lead to an undesirable, under certain circumstances very large temperature change or volume flow change. A serious error operation is therefore not excluded. In order to allow a fine gradation, in such a device beyond a correspondingly large control panel is required.
  • WO 2004/001 142 A1 is a multi-function fitting with a sensor device which is arranged on the front side of an outlet fitting, known.
  • the sensor device has substantially uniformly distributed sensors along a circumference, which act on a controller with microprocessor.
  • the controller in turn acts on an open-close valve and a setting device for the choice of water temperature.
  • the DE 38 12 736 C1 describes a sanitary fitting with a rectangular keypad with arranged in a matrix contact points. Below the keypad a display field is arranged congruently. A controller receives signals from the contact points and is connected to a valve mixing device. Every contact point corresponds to a combination of total water flow and mixing temperature.
  • the DE 103 32 708 B3 discloses an actuator for fittings having a plurality of sensors uniformly distributed along an open curve.
  • the sensors are each assigned to a specific setpoint; If two or more sensors respond simultaneously, an average value of the setpoint values is determined and set.
  • the setpoint values are the temperature and the flow rate.
  • Object of the present invention is to provide a device and a method of the type mentioned above in such a way that a simple and reliable continuous change of fluid flow rates and / or fluid temperatures is made possible.
  • the device should be space-saving and can be realized without great technical effort.
  • the device should be operated as maintenance-free and low-wear.
  • control unit is designed such that it can detect the order sequentially incoming sensor signals, and the change of a parameter then performs when the operation of at least two sensors has been detected successively in time, wherein the control unit determines from the sequence of incoming sensor signals, whether an increase or decrease of the parameter is to be made, and provides a signal therefrom, which acts on the drive unit of the closure device.
  • a parameter for the closure device which specifies in particular a valve lift of the valve, changed via three sensors.
  • a mixing ratio of cold and warm fluid in particular of water
  • a fluid volume flow can be adjusted.
  • at least two adjacent sensors must be actuated one after the other. This is done by stroking the sensors, it does not matter which sensor is started. Since the sensors are arranged along a closed curve, can be started at any point of the curve. Depending on the order in which the sensors are actuated, that is, depending on the direction in which the curve is followed, the parameter is increased or decreased. A labeling of the sensors is therefore not required. It is also an extreme change due to accidental operation a wrong sensor not possible. Incidentally, the arrangement of the three sensors on a closed curve is extremely space-saving.
  • control unit has a decrementer / incrementer with which the parameter can be increased or decreased.
  • a decrementer / increment can be realized without great technical effort, for example by programming the control unit.
  • control unit has a timer with which a time interval can be predetermined, within which two sensor signals are detected as belonging together, that is to say a user-desired actuation of the actuating device is detected.
  • the sensors are especially easy to operate by sweeping over with at least one finger for children and the elderly.
  • the actuator when used as part of a shower fitting, is a water jet and thus possibly exposed to temperature fluctuations.
  • a first particularly advantageous embodiment therefore provides touch sensors, which have the advantage that they are essentially not susceptible to temperature fluctuations.
  • capacitive sensors can be used here, which can be actuated without contact pressure.
  • an alternative advantageous embodiment provides non-contact sensors that can be actuated without direct contact.
  • infrared sensors are provided here, which are particularly simple and can be realized without great technical effort.
  • a particularly advantageous embodiment provides for the sensors to be guided along a guide device for at least one finger are arranged so that the actuator is also blind operated.
  • a particularly advantageous embodiment provides a turntable which has at least one engagement, in particular a finger recess.
  • the engagement is assignable to the sensors in an advantageous embodiment, so that the actuation of the sensors can be done with the finger.
  • the engagement may be a continuous hole in the turntable, in which, upon rotation of the turntable, the finger can be guided along the sensors. In this way, both non-contact and touch sensors can be actuated directly with the finger.
  • the turntable has at least one magnet, which can be guided by rotation of the turntable along the sensors implemented as field probes.
  • Magnets have the advantage that they can be integrated in the turntable, so they can be arranged encapsulated, so that they are invisible from the outside and protected from environmental influences, especially from heat and moisture.
  • the field probes can be arranged encapsulated.
  • the positioning of the engagement relative to the sensors is irrelevant, since the actuation of the sensors does not take place directly with the finger but with the magnet.
  • the turntable has at least one mirror element that can be guided by rotation of the turntable along the sensors implemented as reflected light barriers is.
  • the light emitted by the respective reflected light barrier is reflected at the mirror element as soon as it is guided along the reflected light barrier.
  • At least three sensors are arranged along at least two closed curves, in particular two concentric circles, with which different operating parameters, in particular the water quantity and the water temperature, can be changed.
  • This has the advantage that two different operating parameters can be changed independently of each other.
  • corresponding closure devices in particular a hot water valve and a cold water valve in a hot water line or a cold water line, can then be opened or closed with the control unit.
  • the sequence of successively incoming sensor signals is determined and the control is performed when sensor signals arrive in chronological succession, wherein the direction of the control is determined from the order of the detected sensor signals. In this way, it is prevented as far as possible that an accidental actuation of only one of the sensors already takes place. In addition, by the order in which the at least two adjacent sensors are actuated, it can be determined whether the closure devices should be opened or closed.
  • the closure device is in an advantageous embodiment of the method depending on the order of the two signals and the position of the respective sensors relative to one another, in particular, decrements or increments a parameter that predetermines a valve lift of the valve. Then the drive unit is driven accordingly.
  • the sensors are scanned cyclically, so that the parameter can be decremented or incremented so many times until a valve lift is set, which specifies a desired fluid temperature or a desired fluid volume flow.
  • An advantageous embodiment provides, upon repeated detection of a signal from the same sensor to negate a previous decrement or incrementation in order to reverse a change in the parameters.

  • the user In order to open or close the valve 13, the user must be guided with his finger 6 in the appropriate direction along the guide trough 5 at least two adjacent of the three sensors 2, 3, 4 along.
  • valve 13 Depending on the number of cycles of the finger 6 in the guide trough 5, a degree of opening or closing of the valve 13 is effected with the control unit 10.
