Definitions

  • the present invention relates to a sanitary article for connection to a sewer and a method for producing the sanitary article according to the preambles of the independent claims.
  • Sanitary articles for connection to a sewer serve to discharge solid and liquid waste into the sewage system.
  • such sanitary articles In order to effect a complete transport of the introduced waste into the sewage system and to flush the walls of the sanitary article in contact with the waste, such sanitary articles have in the boundary walls of their receiving space one or more feed openings for rinse water which supplies rinsing water via an internal supply channel become.
  • WO 03/048467 A1 discloses a toilet bowl in which the aforementioned problem is avoided by forming the feed channel for the rinse water by assembling two separate components.
  • the components forming the supply channel have a relatively uncomplicated shape and are correspondingly easy to manufacture.
  • this design principle has the decisive disadvantage that the joints of the supply channel forming components be loaded by the water pressure occurring in the supply channel and can be leaking over time or even fail in the worst case.
  • a first aspect of the invention relates to a sanitary article for connection to a sewer for the discharge of liquid and / or solid wastes into the sewer such as e.g. a water closet, a urinal or a sink.
  • the sanitary article has a receiving space for receiving the waste, which is circumferentially closed and in which from above a receiving opening for gravitational feeds of waste material opens. In its lower region, the receiving space has a discharge opening, via which the supplied waste materials can be discharged into the sewer pipe.
  • the boundary walls of the receiving space are formed by at least two components, which are connected to each other and each of which each component forms a circumferentially closed portion of the boundary walls of the receiving space. These components thus form part of the boundary walls arranged one behind the other in a direction from the receiving opening to the discharge opening.
  • the boundary walls of the receiving space have at least one feed opening for rinsing liquid, via which rinsing liquid flows into the area at different circumferential positions in this area
  • Receiving space can be introduced to transport the introduced waste into the sewer line and to flush with these contacted wall portions of the sanitary article.
  • the term "at least one feed opening" means that a single feed opening can be present, via which rinsing liquid can be introduced into the receiving space in this area at different circumferential positions, or that a plurality of separate feed openings can be present for this purpose.
  • the sanitary article has a supply channel for rinsing liquid, by means of which the at least one feed opening arranged in the region between the receiving opening and the dispensing opening can be supplied with a pressurized rinsing liquid.
  • the feed channel preferably extends in the circumferential direction of the receiving space, so that it can connect the individual feed openings to one another as short as possible with a plurality of separate feed openings and jointly supply them with rinsing liquid or if they extend over the circumference or over a partial area of the circumference of the receiving space Feed opening this can supply evenly over its entire circumferential extent with rinsing liquid.
  • normal tap water is used as flushing liquid, optionally with the addition of fragrances and / or disinfectants.
  • the supply channel for supplying the rinsing liquid to the supply openings and that portion of the boundary walls of the receiving space having the supply openings are formed together by a one-piece component.
  • the invention thus relates to a sanitary article for connection to a sewer pipe with a circumferentially closed receiving space with a receiving opening and a discharge opening.
  • the boundary walls of the receiving space have in a region between the receiving opening and the discharge opening to a supply opening for rinsing liquid, which can be supplied via a supply channel with rinsing liquid, for supplying the same at different circumferential positions in the receiving space.
  • the boundary walls of a plurality of interconnected components are formed, each of which component forms a circumferentially closed portion of the boundary walls.
  • the supply channel and that part of the boundary walls, which has the feed opening for rinsing liquid are formed together by a one-piece component.
  • the embodiment of the sanitary article according to the invention makes it possible to inexpensively provide high quality sanitary articles with internal supply channels for rinsing liquid, in particular of ceramic materials, in high quality.
  • the supply channel is formed as an annular channel or annular channel segment, preferably in such a way that the one-piece component, which forms the portion of the boundary walls of the receiving space having the supply openings for rinsing liquid, consists essentially of the limitations of this supply channel.
  • the sanitary article in the area between the receiving opening and the discharge opening as claimed at least one feed opening" on one or more gap-shaped feed openings, which in the circumferential direction over a peripheral portion or on the extend the entire circumference of the receiving space and can be supplied via the supply channel with rinsing liquid.
  • these can be arranged one behind the other in the circumferential direction next to one another and / or in a direction from the receiving opening to the discharge opening.
  • a single annular nozzle may be present, with which flushing liquid can be supplied over the entire circumference of the receiving space, or an arrangement of a plurality of annular nozzle segments, which are configured in the circumferential direction side by side to a nozzle ring and allow a supply of rinsing liquid over several peripheral portions. It is also provided, for example, to arrange a plurality of such annular nozzles or nozzle rings in a direction from the receiving opening to the discharge opening one behind the other.
  • Such gap-shaped feed openings are particularly suitable for the short-term supply of large quantities of rinsing liquid with relatively small entrance velocities into the receiving space, eg for rinsing a water closet or urinal.
  • the sanitary article in the area between the receiving opening and the discharge opening as claimed "at least one feed opening" on several punctiform, in particular substantially circular feed openings, which arranged distributed in the circumferential direction over a peripheral portion or over the entire circumference of the receiving space are so that they allow a supply of rinsing liquid at several circumferential positions.
  • the punctiform feed openings can be arranged in one direction from the receiving opening to the dispensing opening at identical or different axial positions, in particular in a common plane or in several successive planes.
  • Such point-shaped feed openings are particularly suitable for the supply of smaller quantities of rinsing liquid with relatively large entry velocities in the receiving space, eg for the specific cleaning of certain areas of the receiving space by means of Spülillonkeitsstrahlen and / or for an acceleration of the flow in a leading to the sewer line flow cross-section of the sanitary article in order to improve the transport of waste into the sewer.
  • the punctiform supply openings are designed as jet nozzles and form a nozzle ring or a nozzle ring segment.
  • the individual rinsing liquid jets issuing from the nozzles essentially meet at one point or concentrate in one area, preferably in a region of the boundary walls of the wall Reception room, which is particularly prone to pollution.
  • Combinations of the two abovementioned embodiments of the sanitary article are also provided, ie embodiments in which punctiform and slit-like feed openings are present in the region between the receiving opening and the dispensing opening as the claimed "at least one feed opening”. It is also provided that the sanitary article has more than one area in which a claim "at least one feed opening" is present.
  • the component which forms the subregion of the boundary walls of the receiving space which has the "at least one supply opening" for rinsing liquid, either the partial area adjoining the receiving opening the boundary walls, or the adjacent to the discharge opening portion of the boundary walls or neither forms the adjacent to the receiving opening portion nor the adjoining the discharge opening portion of the boundary walls of the receiving space.
  • one or the other embodiment may be more preferable.
  • combinations of these embodiments are provided, namely, when the sanitary article in a plurality of areas between the receiving opening and the discharge opening has a claim "at least one feed opening".
  • the feed openings for rinsing liquid are arranged in an undercut region of the boundary walls of the receiving space when viewed in the direction of gravity present in the intended use of the sanitary article. This results in the advantage that a deposition of dirt in the region of the feed openings is made more difficult.
  • all components which form the boundary walls of the receiving space made of a ceramic material, preferably made of porcelain or sanitary ware, and materially connected by garnishing. Ceramic materials are preferred in the sanitary sector because of their scratch resistance and resistance to chemical cleaning agents.
  • the components are coated on their surfaces forming the boundary walls of the receiving space with a glaze which extends coherently over the Garnierfugen.
  • the sanitary article in another preferred embodiment of the sanitary article is that component which forms the portion of the boundary walls of the receiving space having the claim "at least one feed opening" for rinsing liquid, formed of metal or plastic and with the other the boundary walls of the receiving space forming members materially, e.g. by gluing, welding or soldering, or frictionally, e.g. by clamping, or positive locking, e.g. by screwing, connected.
  • the remaining components forming the boundary walls of the receiving space are each made of a ceramic material, e.g. made of porcelain or sanitary ware. This results in particularly high quality sanitary article according to this embodiment.
  • a second aspect of the invention relates to a method for producing a sanitary article according to the first aspect of the invention.
  • a first, one-piece component which forms a circumferentially closed passage opening.
  • the boundary walls of the passage opening have in one area one or more feed openings, via which a rinsing liquid can be introduced into the passage opening in this area at different circumferential positions.
  • the supply openings can be supplied with a pressurized rinsing liquid via a supply channel formed by the first component, which preferably extends in the circumferential direction of the first passage opening.
  • At least one further, preferably also one-piece Component provided, which also forms with boundary walls a circumferentially closed passage opening.
  • the first component and the one or more other components are assembled into one unit. This is done in such a way that the boundary walls of the passage openings of these components together form the boundary walls of a peripherally closed receiving space in which rinsing liquid can be introduced at different circumferential positions by applying a rinsing liquid under pressure to the supply channel of the first component via the supply openings of the first component.
  • one-piece components are respectively made of a ceramic material, preferably of porcelain or sanitary ware, which are then joined together by garnishing.
  • the components are coated on their the boundary walls of the receiving space forming surfaces with a coherent over the Garnierfugen extending glaze.
  • FIG. 1 A vertical section through a first inventive sanitary article in the form of a toilet bowl is in Fig. 1 shown.
  • the toilet bowl has between the Klosettrand 11 and the Siphonbogen 12 a circumferentially closed and substantially funnel-shaped receiving space 3, which is accessible from above via a receiving opening 1 and at its lower end, which lies below the Siphonwasserline L, via a discharge opening 4 in opens the siphon sheet 12.
  • annular hollow body 13 which forms the Klosettrand 11 and defines the receiving opening 1
  • a further component 14 which forms the actual funnel-shaped region of the receiving space 3 and the siphon arc 12.
  • These two components 13, 14 are connected to each other by garnishing and together form the boundary walls 2 of the receiving space 3, wherein each of the components 13, 14 each forms a circumferentially closed portion 2d, 2e of this boundary walls 2.
  • the annular hollow body 13 has on its underside a circumferential gap 15 (claim appended feed opening), which can be acted upon by a formed inside the hollow body 13 annular channel 16 (demanding moderate supply channel) with rinse water, so that the exiting from the gap 15 rinse water below the gap 15 arranged areas of the boundary walls 2 of the receiving space 3 in the form of a coherent Spülwasserschleiers and then the transport of any introduced into the receiving space 3 solid and / or liquid substances through the siphon sheet 12 is used in the sewer.
  • a circumferential gap 15 claim appended feed opening
  • the annular channel 16 has a flushing water connection (not shown) via which it can be connected to the supply line of a flushing water source, e.g. a cistern or a flush valve, can be connected.
  • a flushing water source e.g. a cistern or a flush valve
  • Fig. 2 shows a vertical section through a second inventive sanitary article in the form of another toilet bowl, which differs from the in Fig. 1 distinguished lavatory bowl characterized in that the boundary walls 2 of the receiving space 3 in addition to the arranged in the upper region of the receiving space 3 circumferential gap 15 for supplying rinse water in the lower region of the receiving space 3, a plurality of individual jet nozzles 5 (claims punctual supply openings), which in this Region are uniformly distributed over the entire circumference of the receiving space 3 and thus form a nozzle ring, can be introduced through the additional rinse water in the receiving space 3.
  • the jet nozzles 5 can be supplied together with flushing water via a circulating supply channel 6, which has a flushing water connection 17 for connection to the supply line of a flushing water source.
  • the jet nozzles 5 are arranged in an undercut region of the boundary walls 2 and aligned such that they generate downwardly directed rinsing water jets which impinge in a region on the boundary walls 2 of the receiving space 3, which is particularly prone to contamination by substances introduced into the toilet bowl.
  • rinsing water jets are deflected upon impact with the boundary walls 2 such that they flow substantially axially into the siphon arc 12, whereby the flow in the siphon arc 12 accelerates and the removal in particular of solids from the siphon bend in the sewer line is improved.
  • FIG. 1 Another difference to the in Fig. 1 shown toilet bowl is that here the funnel-shaped portion of the receiving space 3 and the siphon bow 12 are not formed by a single component, but of a total of three components 7, 8, 9, of which a first component 7 substantially the funnel-shaped portion of the receiving space. 3 forms a second component 8 substantially the jet nozzles 5 and the supply channel 6 forms and a third component 9 substantially forms the siphon arc 12.
  • the boundary walls 2 of the receiving space 3 are here thus formed by a total of four components 7, 8, 9, 13, wherein each of these components 7, 8, 9, 13 respectively a circumferentially closed portion 2a, 2b, 2c, 2d of the boundary walls 2 forms.
  • All components 7, 8, 9, 13 are connected to each other by garnishing and coated on their the boundary walls 2 of the receiving space 3 forming surfaces with a contiguous over the Garnierfugen 10 a, 10 b, 10 c extending glaze.
