Definitions

  • the invention relates to a method for detecting an impending drain blockage of a sanitary bowl, a sensor arrangement, a sanitary bowl, a pre-wall installation system and a toilet.
  • Sanitary bowls are common components of toilets and urinals. Sanitary bowls are often made of ceramic or metal. Paper or similar materials can clog the drains of sanitary bowls (or similar containers) and cause them to overflow.
  • the (intelligent) detection of the incoming and outgoing water allows the presented method, which can be implemented, for example, with sensors integrated into a pre-wall element, to detect an impending overflow of the bowl. As a result, an alarm can be triggered and, if necessary, the fresh water supply can be stopped.
  • the method offers the particular advantage of being able to detect an impending drain blockage using sensors that can be arranged on the back of the bowl, which is generally inaccessible to users. This allows for the most reliable detection of an impending drain blockage, especially in the event of vandalism.
  • the specific duration can be calculated based on one or more previous observations or measurements (e.g., as an average).
  • the specific duration (for the following flushing process) can be determined based on the time or even set as the time that elapses in an (immediately) previous flushing process between a first significant increase in the temporal progression of the fluid flow measurement through the bowl inlet and a first significant increase in the temporal progression of the fluid flow measurement through the bowl outlet.
  • it can be observed over one or more flushing processes whether the flow time increases from flushing process to flushing process. This allows for the detection of deliberate "clogging and flushing" in a particularly advantageous manner.
  • the measure of the fluid flow can be a volume flow or a mass flow.
  • step c) an impending drain blockage is detected if the time 14 that elapses between a first significant increase in the time course 12 of the measure of the fluid flow through the bowl inlet 3 and a first significant increase in the time course 13 of the measure of the fluid flow through the bowl outlet 4 exceeds the certain duration.
  • the specific duration may be a predetermined duration or a determined typical throughput time from the bowl inlet 3 to the bowl outlet 4.
  • toilet 1 can be protected from deliberate vandalism in public areas by deliberately “blocking and flushing".
  • an alarm can be triggered if an impending drain blockage is detected in step c).
  • the fluid supply to the bowl inlet 3 can be interrupted if an impending drain blockage is detected in step c).

Claims (6)

  1. Procédé, destiné à identifier un risque d'obstruction d'une évacuation d'une cuvette sanitaire (2), dotée d'une arrivée (3) de cuvette et d'une évacuation (4) de cuvette, comprenant au moins les étapes suivantes consistant à :
    a) détecter un niveau pour le flux de liquide à travers l'arrivée (3) de cuvette, à l'aide d'au moins un premier capteur (6), qui est placé dans la zone de l'arrivée (3) de cuvette,
    b) détecter un niveau pour le flux de liquide à travers l'évacuation (4) de cuvette, à l'aide d'au moins un deuxième capteur (7), qui est placé dans la zone de l'évacuation (4) de cuvette,
    c) identifier un risque d'obstruction de l'évacuation, si le temps qui s'écoule entre une première augmentation significative dans l'évolution temporelle du niveau pour le flux de liquide à travers l'arrivée (3) de cuvette et une première augmentation significative dans l'évolution temporelle du niveau pour le flux de liquide à travers l'évacuation (4) de cuvette dépasse une durée définie.
  2. Procédé selon la revendication 1, le niveau pour le flux de liquide étant un débit volumétrique ou un débit massique.
  3. Procédé selon l'une quelconque des revendications précédentes, la durée définie étant une durée prédéfinie ou un temps de passage caractéristique déterminé de l'arrivée (3) de cuvette vers l'évacuation (4) de cuvette.
  4. Procédé selon l'une quelconque des revendications précédentes, une alerte étant délivrée lorsque dans l'étape c), un risque d'obstruction de l'évacuation a été identifié.
  5. Procédé selon l'une quelconque des revendications précédentes, l'alimentation de fluide vers l'arrivée (3) de cuvette étant interrompue lorsque dans l'étape c), un risque d'obstruction de l'évacuation a été identifié.
  6. Procédé selon l'une quelconque des revendications précédentes, la cuvette sanitaire (2) étant une cuvette de toilettes ou un urinoir.
