  • the bottom opening associated with the pressure sensor is preferably integrated in a drain fitting according to the invention. The bottom opening can be below and in Distance from a valve body covering hood or screen can be arranged.
  • An advantageous embodiment of the device according to the invention is characterized in that the measuring and control device is provided with at least one adjusting means by which a maximum water level height or a proportional size, in which the floor drain valve is opened by the actuator is adjustable.
  • the maximum water level can be set flexibly, so that it can be adjusted individually according to the wishes of the user of the bathtub or sanitary pool.
  • this embodiment makes it possible to optimally adapt the device according to the invention to baths of different depths (wall height).
  • the measuring and control device of the device according to the invention is provided with at least one adjustment means by means of which a minimum water level height or a proportional size, in which the floor drain valve is closed by the actuator is adjustable.
  • a minimum water level height or a proportional size, in which the floor drain valve is closed by the actuator is adjustable.
  • a further preferred embodiment of the device according to the invention provides that one end of the line, on which the pressure sensor is arranged, opens to a valve seat surface of the floor drain valve, said end of the line is sealed watertight in the closed state of the floor drain valve by a valve body of the floor drain valve.
  • This embodiment contributes to compact dimensions of the floor drain valve having waste set and also allows easy cleaning of the line provided with the pressure sensor.
  • a further embodiment of the invention provides that the electronic measuring and control device is prepared to check a pressure signal output by the pressure sensor and the actuator activating control current, for example, the motor current de de floor drain valve associated actuator, for plausibility ,
  • a further advantageous embodiment of the invention is characterized in that the electronic measuring and control device has a processor, preferably a microprocessor, and a component monitoring the function of the processor, for example a so-called "watchdog".
  • a processor preferably a microprocessor
  • a component monitoring the function of the processor for example a so-called "watchdog”.
  • This embodiment also contributes to a high reliability of the device according to the invention.
  • a possible malfunction of the processor can be detected and then either signaled or a suitable jump instruction, which cleans up the existing malfunction, are initiated.
  • the signal or the jump instruction serve as a trigger for one or more other components of the device according to the invention, which are intended to eliminate the malfunction. In this way, a complete failure of the device according to the invention caused by software failure can be avoided.
  • the electronic measuring and control device is designed such that it emits an acoustic and / or optical signal in case of malfunction of the processor and / or the pressure sensor and / or the actuator.
  • the user of the device can then optionally reset their measuring and control device in a defined initial state, so that they can then work properly and monitored again.
  • the monitoring component (“watchdog") is embodied, for example, in the processor, preferably a microprocessor, or as a microelectronic component which is mounted together with the processor on a printed circuit board.
  • a further advantageous embodiment of the device according to the invention is characterized in that the electronic measuring and control device and / or the actuator is / are provided with an accumulator.
  • an opening of the floor drain valve and thus an "overflow function" is ensured even in case of power failure.
  • the electronic measuring and control device is provided with a device which monitors the state of charge of the accumulator and triggers an opening of the floor drain valve falls below a predetermined or too low state of charge of the accumulator and / or an acoustic and / or emits optical signal.
  • the line to which the pressure sensor is arranged is designed such that when filling the sanitary basin, in particular a bathtub, with water forms an air bubble in front of the pressure sensor.
  • the air bubble in front of the pressure sensor prevents direct contact with dirty service water and thus contamination, which may affect the proper functioning of the pressure sensor.
  • the bathtub 1 is associated with a water inlet fitting 2, for example, a mixing valve, can be introduced via the water, in particular tempered water in the tub 1.
  • the bottom of the bathtub 1 has a drain opening 3, on which a drain valve having a drain valve is mounted.
  • 4 is a valve body of the bottom drain valve shown schematically.
  • the bathtub 1 is equipped with a device for automatic operation of the floor drain valve depending on the height of the water level (level) W.
  • the device has at least one pressure sensor 5 which detects the height of the water level and is arranged on a line 6 which opens at a bottom opening 7 of the bath 1.
  • the opening 7 can be integrated in the drain fitting.
  • the device comprises an electronic measuring and control device (not shown), to which the measuring signals of the pressure sensor 5 are transmitted, and one with the control device electrically or control-technically connected actuator (not shown) for opening and / or closing the floor drain valve.
  • the actuator is designed for example as a servomotor or solenoid switch.
  • the actuator is preferably coupled to a lever mechanism which acts on the valve body 4 of the floor drain valve.
  • the measuring and control device is provided with at least one adjusting means (not shown), with which a maximum water level h max or a proportional size, in which the floor drain valve is opened by the actuator can be adjusted.
  • the measuring and control device is provided with at least one adjusting means (not shown), with which a minimum water level h min or a proportional size at which the floor drain valve is closed by the actuator, can be adjusted.
  • the bottom opening 7 of the bath 1, at which the line 6 provided with the pressure sensor 5 opens, is arranged at a distance from the floor drain opening 3 or the valve seat surface 8 of the valve body 4.
  • the bottom opening 7 facing away from the end 6.1 of the line 6, however, opens at the valve seat surface 8 of the floor drain valve, so that this end of the conduit 6 is sealed watertight in the closed state of the floor drain valve by the valve body 4.
  • the line 6 is similar or corresponds to a bypass.
  • Fig. 2 is outlined a situation in which the floor drain valve is open and the water level W in the bathtub drops accordingly.
  • the pressure sensor 5 further detects the current height of the water level W and sends a corresponding measurement signal to the measuring and control device. If the water level W falls to or below the predetermined or set minimum water level height h min, the measuring and control device causes the actuator to close the floor drain valve.
  • the closing of the drain valve is in Fig. 2 indicated by the valve body 4 shown, pointing down arrow.
  • the predetermined by the adjustment minimum water level height h min can be, for example, about 300 mm.
  • the device according to the invention thus represents an effective overflow protection in combination with the floor drain valve and makes it possible to produce overflow-proof baths without overflow hole in the tub side wall and without arranged on the outside of the tub wall overflow pipe.
  • the bath 1 sketched in the drawing accordingly has no overflow opening (overflow bore) in its tub side wall.
  • the formation of the line 6 as a bypass has the advantage that the line 6 is flushed when opening the drain valve of draining water and thus cleaned.
