Definitions

  • the present invention relates to a sanitary arrangement according to claim 1 and a method for operating a sanitary arrangement according to claim 18.
  • the present invention is based on an object to provide a sanitary arrangement which has an improved detection of a malfunction of the sanitary arrangement.
  • a sanitary arrangement comprises a sanitary article with a drain connection, a drain pipe connected to the drain connection for carrying away a flushing water mixture when flushing the sanitary article, and a sensor unit.
  • the sensor unit comprises a sensor and a controller.
  • the sensor is designed and arranged to detect at least one flow parameter of the flushing water mixture in the drain pipe and to provide a measured value that corresponds to the at least one measured flow parameter.
  • the controller is designed to evaluate the measured value in such a way that a change in the drainage behavior in the drain pipe that indicates a malfunction can be determined.
  • the cooperating control system has the advantage that a simply designed sensor unit can be provided to detect a malfunction.
  • the sensor is operatively connected to the control system.
  • the operative connection is such that the measured values can be transmitted from the sensor to the control system in the form of electrical signals or data.
  • the sanitary ware can be a toilet bowl, a urinal, a wash basin, a shower or another sanitary ware.
  • the flushing water mixture consists of flushing water that is supplied to the sanitary article during a flush, excrement and toilet paper as well as other objects that are thrown into the sanitary article by users.
  • a malfunction that causes a change in the drainage behavior is, for example, a blockage in the sanitary article, the drain pipe or the downstream pipes.
  • Another malfunction that causes a change in the drainage behavior is, for example, a continuous drainage of a small amount of flushing water due to a defect in a flush valve.
  • control is designed to provide an alarm signal to signalize the change upon detection of said change.
  • the alarm signal can be forwarded to a structure higher up the control system, such as a gateway, a building management system or a cloud structure.
  • the controller is designed to compare a first measured value with a second measured value which was recorded at a different time from the first measured value.
  • the change in a measured value of the flow parameters can be a sign of a malfunction.
  • a sudden, jumpy change in the flow parameter is expected.
  • the flow is slower. This means that the sudden, jumpy change changes to a slow flow.
  • the measured values are recorded over time in such a way that a temporal measured value curve is provided.
  • the temporal measured value curve can be compared with a defined measured value curve by the control system. If a defined deviation between the temporal measured value curve and the defined measured value curve is exceeded, the change can be detected.
  • the defined measured value curve can be adapted based on changes in a large number of measured value curves over time.
  • the defined measured value curve can be adapted using software that works according to the principles of artificial intelligence.
  • the sanitary arrangement further comprises a flushing unit.
  • a flushing process of the sanitary article can be triggered.
  • the flushing unit provides a start signal for the control system in such a way that the sensor can record the measured values.
  • the flushing unit is operatively connected to the control system in such a way that the start signal can be transmitted to the control system.
  • the flushing unit preferably comprises an actuating element, a cistern with a flush valve and a flush pipe which connects the cistern to the sanitary article.
  • the actuating element can have an actuating button which can be actuated by the user or a sensor which detects a user. When actuated or detected, the flush valve is actuated and a flushing process is initiated.

  • the sensor is preferably located outside the sanitary article.
  • the senor is arranged outside the drain pipe and thus does not come into contact with the flushing water mixture.
  • the sensor is arranged directly on the outer surface of the drain pipe.
  • the sensor is arranged at a distance from the outer surface of the drain pipe. The distance is preferably in the range of 1.0 to 50 millimeters, in particular in the range of 5 to 20 millimeters.

  • This unit can be inserted into the above-mentioned electrical socket. Alternatively, the unit can also be arranged as such.
  • the senor is a radar sensor, wherein the radar sensor emits sensor waves in the range of 55 GHz to 65 GHz, in particular at 60 GHz.
  • the tube is made of plastic.
  • Such tubes are transparent or permeable to the sensor waves mentioned.
  • the sensor can also be a capacitive sensor or an ultrasonic sensor or a temperature sensor or a calorimetric sensor or an acceleration sensor.
  • the acceleration sensor can be used to detect shocks, vibrations or movements caused by the flow of the flushing water mixture. If a blockage in the drain pipe becomes apparent, the shocks, vibrations or movements are recorded.
  • a first step the at least one flow parameter is recorded with the sensor and a measured value corresponding to the at least one flow parameter is provided.
  • the measured value is evaluated by the control system in such a way that a change in the drainage behavior in the drain pipe that indicates a malfunction can be determined.
  • control when the control detects a change in the drainage behavior in the drain pipe, it provides an alarm signal to signal the change.
  • the above-mentioned flushing unit can be controlled in such a way that no further flushing is triggered.
  • the sanitary arrangement 1 comprises a sanitary article 2 with a drain connection 3, a drain pipe 4 connected to the drain connection 3 for carrying away a flushing water mixture when the sanitary article 2 is flushed and a sensor unit 5.

  • the sensor 6 transmits the measured value via the operative connection between the sensor 6 and the controller 7 and the controller 7 can then evaluate the measured value.
  • the controller 7 can have a processor or a similar element that can evaluate the measured values accordingly.
  • the change in the drainage behavior typically indicates a malfunction.
  • a malfunction can be, for example, a blockage in the sanitary article 2, in the drain pipe 4 itself or in the downstream pipe system.
  • Another malfunction is a defective flush valve in a cistern 10 upstream of the sanitary article 2, which can lead to a constant flow of water in the drain pipe 4.
  • the controller 7 is designed in such a way that, when the said change or malfunction is detected, it provides an alarm signal to signal the change.
  • the alarm signal can be an acoustic alarm, for example.
  • the alarm signal can also be a digital alarm signal that can be transmitted from the controller 7 to a higher-level structure, such as a building management system, a gateway or a cloud structure. This can be used to summon cleaning staff or maintenance staff, for example.
  • the controller 7 is preferably designed to compare a first measured value with a second measured value that was recorded at a different time from the first measured value.
