Definitions

  • the invention relates to the field of flushing water distributors for sanitary articles, in particular for sanitary articles made of ceramic, for example toilets or urinals.
  • the invention includes a flushing water distributor for use with a sanitary article.
  • the flushing water distributor has a supply line with an inlet opening and at least two outlet openings.
  • the inlet opening is preferably arranged at an inlet end of the flushing water distributor, and the at least two outlet openings at an outlet end of the flushing water distributor opposite the inlet opening.
  • a jet splitter is arranged in the supply line, which divides the supply line into at least two distribution channels on the outlet side in order to divide a flushing water stream into at least two partial streams.
  • the distribution channels open into at least two outlet openings.
  • the beam splitter has a conical end region on the inlet side for a punctiform beam splitting. The jet splitter tapers towards the inlet opening and essentially tapers towards a point towards the inlet opening.
  • a flushing water stream enters the flushing water distributor through the inlet opening of the supply line and flows through it, is divided therein, and flows out of the flushing water distributor again through the at least two outlet openings in the form of at least two partial streams. Due to the conical end of the jet splitter in the supply line, an interference point in the form of a single point is created for the flushing water flow. This minimizes contact losses of rinsing water with the rinsing water distributor to a minimum.
  • the flushing water distributor according to the invention has no edges of walls or baffle plates, which are used for jet splitting in conventional flushing water distributors. As a result, pressure losses in the flushing water can be kept low in the flushing water distributor according to the invention. A pressure loss is preferably reduced to such an extent that effective cleaning of a sanitary article, preferably a sanitary ceramic, in particular a toilet, for example a shower toilet, or a urinal, takes place with minimal energy requirements for a flushing system.
  • a flow of rinsing water continues through the rinsing water distributor around the conical end region of the jet splitter.
  • the jet splitter also has no edges further downstream, i.e. on the outlet side, so that a flushing water stream is divided into its partial streams and guided in the distribution channels essentially without significant pressure losses.
  • Such a controlled water flow is preferably achieved by means of continuously extending guide surfaces.
  • Friction losses can be reduced by using suitable materials, for example with if possible Smooth surfaces and the shortest possible lengths of the flushing water distributor can be kept to a minimum.
  • the beam splitter preferably has guide surfaces which continuously adjoin the conical end region.
  • the guide surfaces form side walls of the at least two distribution channels.
  • all of the inner walls of the flushing water distributor are continuous and therefore preferably do not have any edges which could form interference points for the flushing water flowing through the flushing water distributor. Any edges that may be present are preferably arranged in the direction of flow.
  • a flushing water distributor designed in this way is optimized in terms of flow and, due to the minimized pressure loss in the flushing water distributor, is particularly suitable for flushing systems with low supply energy, such as flushing systems with a small pump.
  • a rinse water distributor preferably has two to five partial streams, particularly preferably two or three partial streams.
  • a supply line of a flushing water distributor has a central longitudinal axis and is preferably a pipe with a round cross section.
  • the conical end region of the beam splitter preferably has the shape of a cone.
  • the cone is preferably a circular cone with a circle as an imaginary base surface.
  • the cone can also be a cone with flattened sides, for example with an oval or elliptical base surface.
  • the conical end region of the beam splitter is preferably arranged on or parallel to a central longitudinal axis of the supply line.
  • a cone tip is arranged on the central longitudinal axis of the supply line.
  • an axis of symmetry (e.g. flattened cone) or an axis of rotation (e.g. circular cone) of the conical end region of the beam splitter lies on the central longitudinal axis of the supply line. This allows the flushing water flow to be divided symmetrically and regularly into two or more partial flows.
  • Distribution channels can be in fluid communication with one another or can be separate from one another. Preferably, the at least two distribution channels are completely separated from one another, i.e. without fluid connection. Distribution channels can be designed as separate line sections up to their respective outlet opening. Distribution channels can also be integrated into a common line or a common housing. For example, two or more distribution channels can at least partially have one or more common channel walls.
  • a rinse water stream can essentially be divided into partial streams in the rinse water distributor. Accordingly, distribution channels can be arranged essentially arbitrarily in the flushing water distributor. Distribution channels are preferably arranged symmetrically in the flushing water distributor.
  • a flushing water distributor is arranged, for example, in or immediately after a deflection part, for example a corner valve or an elbow, in a water installation, an asymmetrical design of the flushing water distributor is preferably used.
  • the at least two distribution channels preferably form an upper side channel and a lower main channel.
  • 'top' and 'bottom' are understood to mean a vertical direction, which also corresponds to an installation position of the flush water distributor in a sanitary item.
  • flushing water is guided essentially in a straight line through the flushing water distributor, with an outlet opening preferably directed downward towards a base of a sanitary article.
  • a side channel is used to introduce flushing water in a lateral direction into a sanitary item, for example under an edge of a toilet bowl and/or to generate a circulating flow into a sanitary item.
  • the at least two outlet openings of the flushing water distributor are arranged at an angle to the inlet opening or are arranged at an angle to one another.
  • the at least two outlet openings can also be arranged at an angle to the inlet opening and to one another.

  • a distribution channel can be straight or curved. It can be arranged as a whole tilted or angled relative to a longitudinal axis of the flushing water distributor.
  • a distribution channel preferably has a curved end region, such that the outlet opening of the distribution channel is arranged at an angle relative to an inlet opening of the supply line.

  • the bowl top 63 is formed by a flat surface.
  • the bowl 60 In a rear area of the bowl 60, the area of the rinsing water supply, the bowl 60 has an edge 631 which projects downward into the bowl in the direction of the bowl base 61. This edge covers the part of the flushing water distributor 1 which projects into the bowl 60 when the flushing water distributor 1 is installed. This essentially concerns the end regions of the distribution channels 30,31,32.
  • the rear bowl wall area 620 has a passage 621 with a wall opening 622.
  • the flushing water distributor 1 is installed in the passage 621 and protrudes through the wall opening 622 into the bowl.
  • the flushing water distributor 1 is aligned essentially horizontally, i.e. a central or longitudinal axis 5 of the flushing water distributor 1 is introduced essentially horizontally in the toilet 6.
  • the lower outlet opening 24 of the flushing water distributor 1 points downwards approximately parallel to the inside of the rear bowl wall area 620.
  • the lower outlet opening is angled at approximately 15 to 30 degrees from the vertical and therefore does not point exactly vertically downwards.
  • a jet of rinsing water therefore does not hit the inside of the bowl wall or hits it at a very shallow angle, for example a few degrees, such as 1 to 5 degrees.
  • One of the two side outlet openings 22,23 shows in the Figure 12 up, the other down. A jet of water is thus flushed into the toilet bowl 60 on the right and a second on the left under the edge 631.
  • the housing 45 of the flushing water distributor 1 is held in the wall passage 621.
  • the housing stop 450 is prevented from being inserted further by a stop in the wall passage 621.
  • the flushing water distributor 1 is held on the inner wall of the bowl 60 due to the laterally angled side channels 31, 32, possibly also the downwardly angled main channel.
  • the distribution channels in particular the side channels 31, 32, are arranged on the rear inner wall of the bowl in such a way that flushing water, which flows from the outlet openings of the side channels 31, 32, flows practically seamlessly from the side channel along the inner wall of the bowl into the side areas of the bowl 60.
  • Two spring elements 70,71 are inserted between the flush water distributor 1 and toilet 6. These enable or improve the tensioning of the flushing water distributor 1 in the assembled state and optimize the flow of flushing water from the flushing water distributor 1 into the toilet bowl as smoothly as possible.
  • the first spring element 71 is mounted in the wall passage 621 between the housing 45 of the flushing water distributor 1 and the stop in the wall passage 621.
  • the first spring element 71 is preferably designed to be circumferential and can be an elastic ring.
  • the second spring element 70 is arranged between the edge 631 and the angled areas of the side channels 31, 32. If the flushing water distributor 1 is brought into its installation position, the second spring element 70 abuts against the inside of the edge 631. The two ends 700 of the spring element 70 press against the insertion direction on the two side channels 31, 32. This means that the two side channels are pressed laterally outwards and against the rear inside of the bowl wall. The flushing water distributor 1 is therefore also secured against unintentional displacement against the direction of insertion.
  • the outlet openings of the side channels rest on the rear inner wall of the bowl with the exception of a distribution channel wall thickness. This transition can be optimized by a special design of an outlet opening of a side channel. This will be discussed below Fig. 16 described in more detail.
  • a water pipe (not shown) is sealingly connected from behind to the water supply pipe 2 of the flushing water distributor 1, preferably screwed.
  • the wall passage 621 with wall opening 622 is located as high as possible in the toilet bowl and thus as close as possible to the top of the bowl 63 in order to enable water inlet from the top of the bowl if possible.
  • the flushing water distributors shown in the examples have preferred circular pipe diameters for supply lines.
  • formed pipe flows are present therein, so that a jet splitter arranged in the middle of such a pipe has an optimal effect with regard to pipe flow and flow division.
  • a jet splitter can also be arranged asymmetrically, in particular off-center, in a cross section of a supply line.
  • a flushing water distributor 1 with back wall flushing is shown.
  • the flushing water distributor also has an additional cleaning channel 34 with a corresponding return outlet opening 340.
  • the cleaning channel 34 is arranged below the main channel 30.
  • the outlet opening 24 of the main channel 30 is arranged at an angle of approximately 30 degrees to 45 degrees to a vertical and to the schematically shown rear wall 64 of a sanitary article.
  • a flushing stream through the main channel 30 therefore generally does not hit the rear inner wall or rear wall 64 of the sanitary item, but is directed directly into the outlet of a toilet.
  • the rear outlet opening 340 is directed towards the rear wall 64 of the sanitary article.
  • the separate cleaning channel 34 is dimensioned such that only a small part 50 of a flushing stream is passed through a cleaning channel 34.
  • this part 50 hits the rear wall 64 at low speed and low pressure, such that the widest possible film of water is formed along the rear wall 64.
  • the flushing jet intended for back wall flushing strikes the rear wall 64 at an angle 640 of, for example, 30 degrees to 60 degrees. In these In angular areas, excessive splashing water can be prevented and the rear wall 64 of the sanitary article can be cleaned efficiently
  • Fig. 14 is the flush water distributor from Fig. 13 shown with integrated odor extraction function. Odor extraction takes place in the example of Fig. 14 via main channel 30 and via cleaning channel 34. An air suction stream 51 is shown with arrows.
  • the flushing water distributor 1 is connected to a fan or a pump, for example, for odor extraction.
  • a corresponding valve for example a multi-way valve, can be arranged in the flushing water distributor 1 or upstream in the flushing or water installation system.
  • a suction device in particular a fan, is connected to a first inlet of a reusable valve.
  • a flushing water supply for example from a water installation, is connected to a second input of the reusable valve.
  • the output of the multi-way valve is connected to the supply line 2 of the flushing water distributor 1.
  • the valve is preferably connected in a closed and preferably de-energized state as a connection from the first input to the output.
  • the flushing water distributor 1 When the valve is closed, the flushing water distributor 1 is in the odor extraction function.
  • the valve When flushing, the valve is switched so that the second input is connected to the output. This clears the path for rinsing water through the rinsing water distributor 1.
  • the direction of flushing water is in the opposite direction to an air flow sucked out through the flushing water distributor.
  • Fig. 15 shows a rinse water distributor, for example according to Fig. 13 , with a detergent line 9.
  • the detergent line 9 is a separate line which is arranged outside and parallel to the supply line 2.
  • Through the Rinsing agent line 9 can be used to introduce a substance 95, preferably a liquid, such as dishwashing liquid or cleaning agent, into the rinse water and thus into the sanitary article.
  • the detergent line 9 has an external connection 90.
  • a supply line for example a hose of a cleaning agent reservoir, can be connected to the detergent line 9.
  • An inner end 91 of the rinsing agent line 9 opens from above into the supply line 2 in the area of the jet splitter 40. A substance is thus essentially only introduced into the side channels 31, 32 arranged at the top of the rinsing water distributor 1 and thus preferably only into the one or more side streams buried.
  • Fig. 16 shows an outlet area of a side channel 31 with the end 301 of the side channel 31 resting against a rear wall 64 of a sanitary article.
  • the side channel 31 is specially designed around its outlet opening 22.
  • an outlet opening 22 of a side channel 31 is formed by a cut end of the side channel.
  • the edges of the side channel ends form tear-off edges for the side flushing flow 52. This is in the embodiment of the side channel 31 in Fig. 16 This is also the case in an area 302 of the side channel 31 remote from the rear wall.
  • the outlet opening 22 is surrounded by differently designed side walls.
  • the oval outlet opening 22 is formed on the rear wall by an externally flattened side wall 304. This guarantees that the end 301 of the side channel 31 rests in a positive manner on the rear wall 64.
  • a rounded side wall 303 is shaped to taper in the direction of flow.
  • the side channel 31 is in the area in which it rests on the rear wall 64 and in a lower area ending approximately in the middle of the side channel 31, namely rounded and essentially shaped as a quarter circle (viewed in cross section).
  • a flow transition of the side flow 52 in a wall area can be designed with little disruption.
