Definitions

  • the present invention relates to a shower toilet, a method for operating a toilet and the use of a shower toilet.
  • Water closets (WCs) with a bidet function have been known and used for a long time.
  • a toilet is additionally equipped with at least one shower for cleaning the user's abdomen, which is often referred to as an under-shower for short.
  • a motorized, movable shower arm in the under-shower can move forward into the toilet bowl in response to an operating operation and direct a shower water jet upwards and move back according to function.
  • shower facilities are equipped with other facilities, for example water heaters such as boilers or instantaneous water heaters, hair dryer facilities, shower arm cleaning facilities, etc.
  • Conventional shower arm cleaning devices usually include a rinse water hose with which rinse water is applied tangentially to the end face of the shower arm when the shower arm is retracted in order to clean it.
  • a conventional shower arm cleaning device is, for example, in DE 20 2012 001 170 U1 described.
  • One object of the present invention is, in particular, to improve hygiene in a shower toilet comprising a spray nozzle with a cleaning function.
  • the shower toilet according to the invention is distinguished from the shower toilets known from the prior art with a cleaning function of the shower arm in that the shower arm (spray nozzle) in the rest position is sprayed not only with pure rinse water, but also with a disinfectant and thus is cleaned. For this reason includes the spray device, in addition to the water supply known from the prior art, also has a disinfectant supply, with a disinfectant being able to be conveyed via the disinfectant supply while the spray nozzle is in the rest position.
  • the water and the disinfectant intended for cleaning the spray nozzle can be applied separately from one another via separate outlets to the front side of the spray nozzle.
  • the spray device comprises a separate water outlet and a separate disinfectant outlet, each adjacent to the front side of the spray nozzle, via which these two liquids are applied to the spray nozzle either simultaneously or one after the other for the purpose of cleaning or disinfection.
  • the spray device comprises an outlet adjacent to the front side of the spray nozzle, through which the mixture of water and disinfectant is applied for the purpose of cleaning or disinfection.
  • the disinfectant supply has a disinfectant conveyor, which is a pump.
  • a disinfectant conveyor which is a pump.
  • the water supply and the disinfectant supply are connected to the spray nozzle via a mixer.
  • the disinfectant can also be sprayed through the water supply using a suction jet are conveyed into the spray device, in which case the line through which the water applied to clean the spray nozzle is supplied acts as a suction jet pump.
  • the disinfectant supply is connected to a disinfectant tank.
  • the disinfectant supply opens into a disinfectant outlet, the disinfectant outlet preferably being arranged adjacent to the spray nozzle. If, as described above, the water intended for cleaning the spray nozzle and the disinfectant are applied as a mixture to the spray nozzle, the disinfectant outlet corresponds to the outlet through which the mixture of water and disinfectant is applied to the spray nozzle from the outside.
  • the water supply or the disinfectant supply or both have a plastic tube.
  • FIG 1 shows the shower toilet 1 according to the invention with spray nozzle 5 in the use position 7 (picture above) and with spray nozzle 5 in the rest position 6 (picture below).
  • the shower toilet includes a toilet bowl 2 with a bowl space 3, into which the spray nozzle 5 protrudes in the use position 7 (illustration above in the Figure 1 ).
  • the spray nozzle 5 is almost completely retracted into the toilet bowl 3 (illustration below in the Figure 1 ).
  • This shower toilet corresponds in its basic arrangement to those shower toilets with a cleaning function that are known from the prior art.
  • FIG. 2 now shows a side view of a spray device 4 removed from the shower toilet with a cleaning function, comprising a tubular and displaceably arranged spray nozzle 5 in the rest position 7.
  • a water supply 8 can be seen, via which water flows into the spray device 4 in order to create the spray nozzle 5 in it via an outlet 12 (see Figure 3 ) to be cleaned on the front side.
  • a disinfectant is now introduced into the spray device 4 from a disinfectant tank 13 via a disinfectant supply 9. Like in the Figure 2 shown, the disinfectant is introduced via the rinsing water line, which acts as a suction jet pump.
  • the resulting mixture of water and disinfectant is now via the disinfectant outlet 12 (see Figure 3 ) is applied to the front side of the spray nozzle 5 in order to clean it from the outside and in particular to disinfect it. It is also conceivable to supply the disinfectant via a separate pump (in Figure 2 not shown) and, if necessary, via a separate additional outlet (in Figure 2 also not shown) to be applied separately from the water to the front side of the spray nozzle 5. Furthermore, a cover 14 can be provided at the end of the spray device 4, which faces the bowl space 3. The cover 14 is closed, ie it is essentially flush with the bowl space 3 when the spray nozzle 5 is in the rest position.
  • Figure 3 shows the supervision on the in Figure 2 with a bold arrow with the cover 14 closed area of the spray device 4.
  • a play chamber 15 is formed which has a nozzle outlet 16 of the nozzle 5 and a disinfectant outlet 12.
