Definitions

  • the present invention relates to a toilet bowl.
  • the present invention also relates to a rinse water conditioner container for use with the toilet bowl of the invention.
  • the invention further relates to a tablet for use in a rinse water conditioner container of the invention.
  • the invention relates to a toilet bowl system comprising the toilet bowl according to the invention and a Spülwasserkonditionierstoff mater invention.
  • the present invention relates to a use of a tablet according to the invention in a toilet bowl system of the invention and a method for conditioning and rinsing a toilet bowl.
  • a toilet bowl includes a water inlet opening through which flushing water from a cistern enters the toilet bowl. Furthermore, the toilet bowl comprises a drain opening through which the rinse water leaves the toilet bowl together with the feces during the rinsing process.
  • the water inlet opening and the drain opening are in fluid communication with each other via a rinsing chamber and a sink.
  • the flushing chamber which is delimited upstream of the water inlet opening, serves to distribute the flushing water in the toilet bowl before exiting into the sink.
  • the rinsing chamber is provided at the upper edge of the sink and forms with its top a seating plane which serves as a support surface for the toilet seat.
  • the rinsing chamber has a first chamber area, into which the rinsing water is introduced before it is passed via a downstream provided branching in the two side chamber areas or in the toilet bowl.
  • This first chamber area is designed in such a way that, in the case of a flushing, there is a short-term congestion of flushing water and thus complete filling of this first chamber area.
  • the rinsing chamber, and thus also the first chamber area is empty, because the rinsing water runs through openings in the lower area of the rinsing chamber into the rinsing area.
  • the rinse water depending on its lime content leads to deposits in the toilet bowl.
  • the deposits close the openings in the lower part of the rinsing chamber through which the rinse water drains into the bowl, the effectiveness of the rinse and after their repeated repetition is required. In this way, the water consumption of the toilet bowl increases dramatically.
  • Conventional cleaning procedures which are performed at regular intervals, do not eliminate the deposits in openings in the lower part of the washing chamber.
  • DE-C1 100 32 439 proposes for cleaning in particular the edge of the pool a method in which the rinse water is stowed with a special device in the toilet bowl to the edge region, thereby contacting the edge region with a detergent that the rinse water in Form of an effervescent tablet is added to allow. This procedure prevents the use of the toilet over a longer period and requires a complex and bulky cleaning device,
  • the treatment agents may be introduced into the toilet bowl, for example in a lumpy shape, for example in a cage-like container under the inner edge.
  • Known toilet blocks contain cleaning or active ingredients, which are dissolved in each rinse in small amount from the incoming rinse water and in the Basin are distributed (EP-A2 1 291 469).
  • the cleaning block is positioned in the cistern of the toilet (US-A 6,651,260). The block gradually dissolves there, and the water entering the toilet bowl contains a content of active ingredients for a long time.
  • the rinse water is conditioned only after exiting the rinsing chamber, wherein a calcification of the outlet openings of the rinsing chamber can not be influenced.
  • a dosage can hardly be controlled because the active ingredient content in the rinse water depends on the residence time of the rinse water in the cistern.
  • this method depends on the cistern being easily accessible to the user so that the treating agent can be renewed if necessary.
  • the present invention is based on the recognition that it is possible within the rinsing chamber during a single rinse pulse to condition the rinse water irrespective of the residence time of the water in the cistern such that a high cleaning effect, in particular with regard to the calcification of the openings of the rinsing chamber or Urinsteinablagerungen in the sink, is achieved.
  • the toilet bowl according to the invention has the advantage that the treatment agent can be fed in such a way that all areas of the toilet bowl, including the rinsing chamber, are treated.
  • the rinse water which is transported through the rinsing chamber in the final phase of rinsing and remains between the rinses in the toilet bowl, is more strongly exposed to the treatment agent than the water of the initial phase, which leaves the toilet bowl with the feces.
  • a solid treating agent such as a tablet
  • the opening of the rinsing chamber is provided in a first chamber region, which is present downstream of the water inlet opening and extends in the flow direction as far as the rinsing basin.
  • the opening of the washing chamber is present above a central axis A-A 'of the toilet bowl.
  • the opening of the rinsing chamber is upstream of a branch, with which rinsing water are discharged into side regions of the rinsing chamber.
  • the opening of the rinsing chamber is circular.
  • the opening of the washing chamber is perpendicular to the seating plane.

  • FIG. 1 shows a schematic representation of a toilet bowl according to the invention with indicated by arrows flow directions of the rinse water.
  • the toilet bowl has a water inlet opening 1 and a drain opening 4.
  • the water inlet opening communicates with a rinsing chamber in the edge area of the sink, with the sink and with the drain opening in flow communication.
  • Rinsing water enters through the water inlet opening 1 into a first chamber region 21 of the rinsing chamber 2, which is present downstream of the water inlet opening 1 and extends in the flow direction as far as the rinsing basin 3.
  • the first chamber area 21 is designed in such a way that, during a flushing, it causes a brief stagnation of flushing water, so that the first chamber area 21 fills completely with flushing water for a short time.
  • the rinse water will be from the first Chamber area each in a left side chamber area 22 and a right side chamber area 23 derived, and partially via one or more opening 211 in the sink.
  • the left side chamber area 22 and the right side chamber area 23 have at the bottom openings 221, 231 through which the rinse water from the side chambers in the edge region is introduced into the sink.
