Definitions

  • This object is achieved according to claim 1 by using a method for cleaning a toilet bowl using flushing water present in a cistern, which is heated by an electrical heater arranged in the cistern to a temperature at which the flushing water is a desired one Cleaning effect unfolds.
  • Water also has a disinfecting and cleaning effect, resulting in less pollution of the wastewater.
  • Embodiments of the invention are specified in claims 2 to 20.
  • Claim 2 provides that the electric heater provided in the cistern for carrying out the method according to claim 1 is coupled to a device for measuring the water temperature in such a way that the heater switches off after a certain temperature has been reached. This minimizes energy consumption in a simple manner and prevents damage caused by evaporation of the water.
  • the flushing process can be triggered precisely when the flushing water has its desired temperature.
  • Suitable display means are, for example, a signal lamp or an on / off switch which, in conjunction with the device for measuring the water temperature, signals the end of the heating process optically and acoustically by means of its position or a characteristic “click”. If, according to claim 4, a device for automatically triggering the rinsing process is provided after reaching the desired water temperature, there is no waiting time during operation. In accordance with claim 5, an automatic timer for independently initiating the flushing process at a predetermined time can be provided, so that the toilet bowl can be cleaned without human labor. In particular, automatic cleaning is also possible several times in succession in order to further increase the cleaning effect.
  • a switch-on lock is provided, unauthorized rinsing with heated water is prevented.
  • This can e.g. with a lockable lid, an electronic combination lock or similar respectively.
  • This prevents excessive use of hot water, so that in fact only the additional cleaning of the toilet bowl takes place, but not every flushing process with hot water.
  • Abuses in particular are excluded for publicly accessible toilets and toilets that are also used by children.
  • a division of the cistern by at least one partition is very economical, so that the respective amount of water in the individual parts can be heated independently of one another. In this way, both the energy and the water expenditure can be adapted to the cleaning requirements.
  • a device which indicates a possible use of the toilet before the flushing process is initiated automatically.
  • this can be a device that registers before the automatic initiation of the flushing process whether a cover of the toilet bowl is closed. By coupling the initiation of the flushing process to the closed state of the cover, one reliably prevents users of the toilet from being injured by heated water, for example if the flushing malfunctions.
  • Suitable facilities are e.g. an electrical contact between the cover and its attachment to the toilet bowl.
  • a device for detecting the angle of inclination of a hinged lid can also be used with advantage.
  • a weight meter is suitable as a detector, which detects the load on a toilet seat.
  • optical or ultrasonic sensors can be present which report the presence of a body and / or a movement in the immediate area of the toilet bowl.
  • a further embodiment according to claim 15 is that a cleaning mechanism for the toilet bowl protrudes with a part into the cistern, so that hygienic cleaning of this cleaning mechanism is also possible and can be carried out automatically.
  • This cleaning mechanism can be a fully automatic cleaning gripper arm or a commercially available toilet brush, which can be opened in a cover
  • Water tank of the toilet flush is inserted so that it protrudes, whereby it is disinfected when the water is heated.
  • the cover of the opening of the cistern can also be firmly connected to the toilet brush.
  • a scraper can either be attached directly to the opening in the cistern, or it can be designed as an extendable mechanism.
  • Such a pull-out or fold-out mechanism makes it possible to guide the toilet brush over the middle of the wash bowl without water drops reaching the edge of the toilet bowl.
  • a device is provided which uses the heated water or steam from the cistern to spray the toilet bowl or the closer surroundings. This makes it easy to hygienically clean and disinfect dirt that is difficult to dissolve in the wash bowl and, above all, dirt on the cover of the wash bowl or the outside of the toilet bowl or in the immediate vicinity, without chemicals.
  • Such a device for spraying can be a device according to claim 19, the hot water jet of which can be directed to different areas of the toilet bowl and its cover by hand.
  • the cleaning effect is also improved by spraying devices that are permanently installed in the toilet bowl.
  • Such spray nozzles also use the hot water in the cistern to spray the interior of the toilet bowl.
  • the spray nozzles can be attached to the upper inner edge of the toilet bowl so that all areas of the interior of the toilet bowl are caught by a water jet. This enables fully automated and therefore personnel-saving cleaning of the toilet bowl, even if it is very dirty.

Abstract

On utilise normalement de l'eau froide pour nettoyer une cuvette de W.C. ou un urinoir au moyen d'une chasse d'eau. Pour bien nettoyer la cuvette, il faut en outre la nettoyer à intervalles réguliers avec des substances chimiques ou des procédés mécaniques. Afin de résoudre ce problème, l'invention propose un réservoir de chasse d'eau dont l'eau peut être électriquement chauffée et qui est le cas échéant couplé à un dispositif de mesure de la température, d'indication de la fin du chauffage, d'interruption du chauffage une fois qu'une température déterminée est atteinte, de chasse automatique ou de réglage variable de la température atteinte à la fin du chauffage. L'invention concerne également des dispositifs qui déterminent ou enregistrent le niveau d'eau dans la cuvette avant de déclencher automatiquement la chasse, qui détectent si le couvercle de la cuvette est fermé ou si des personnes se trouvent dans le cabinet de toilettes. D'autres dispositifs permettent d'utiliser l'eau chaude pour désinfecter le balai du W.C. ou pour nettoyer la cuvette de W.C. et son environnement immédiat au moyen d'un mécanisme de pulvérisation.
