Definitions

  • the invention relates to a toilet with a toilet body and a shower device comprising a downstream water connection valve, a water heater and the heated water dispensing, running in the toilet body shower rod.
  • WCs with integrated or installed shower facilities are becoming increasingly popular. They allow cleaning with water, which allows effective cleaning and is advantageous for hygienic reasons, but also gives a pleasant feeling.
  • the shower device is supplied with the water, which is controlled via a water connection and a downstream valve, supplied to the shower device, usually a shower rod, coming from behind in the toilet body runs. The shower rod is this, if needed, moved into the toilet body, which can be done for example via a corresponding electric motor drive.
  • tank heaters are known, d.
  • a water reservoir is provided in the form of a tank having an integrated heater, after which the water is withdrawn from the tank or pumped out.
  • the WC in question has a water heater, through which the water supplied from the water connection or via the valve flows and is heated in this case, after which it is supplied to the shower rod.
  • the invention is therefore based on the problem to provide a toilet of the type mentioned, which has an integrated open air route, but is simple in construction.
  • the water heater is followed by an injector having a free-jet injector from which the water via a line directly to the shower rod or to a manifold component, via another line with the shower rod connected, passes.
  • the WC is characterized by the integration of an injector downstream of the instantaneous water heater, which has the open air section, respectively, in which it is integrated.
  • the injector is used for beam acceleration, which is realized by corresponding cross-sectional changes, which will be discussed below, within the flow paths.
  • the water coming from the instantaneous water heater flows directly to it.
  • the free jet route ie the open air route, which serves for the decoupling and prevents the sucking back, is provided or structurally integrated in the injector. From the injector, the heated water passes either directly to the shower rod, where it flows to the outlet nozzle.
  • the coming of the injector water can also pass through a line to a manifold component, which is a simple valve through which the inflowing water can be distributed, for example, on several downstream lines, and via which it reaches the shower rod, where then finally delivered.
  • the injector does not generate a back pressure Components are connected downstream. If that were so, it would not be possible due to a possible backwater within the injector to lead the water with a sufficiently stable jet over the open air route, but it would be due to the back pressure to unstable conditions, combined with a high leakage water content.
  • the injector after the injector on the one hand only components are connected downstream, generate no increased back pressure respectively line cross sections are used, which have a sufficient diameter, it is ensured that the water can be performed with a stable beam over the open air section.
  • the injector serves for the formation of the free jet route.
  • the inflowing water is formed in the injector to a sufficiently sharp jet, which bridges the free jet path under a sufficient pressure. If the inlet valve, which is connected upstream of the water heater, closed again, then no more water flows and the jet collapses, the free jet line ultimately separates the toilet from the supply line respectively the house installation.
  • the injector has a housing with a cavity, which has the free jet path, which extends from a nozzle emitting a water jet to a nozzle receiving the water jet, wherein the housing has a drain opening for itself in the Having cavity accumulating, to be discharged into the toilet body leakage water.
  • the free jet distance is ultimately limited by two nozzles.
  • the inlet-side nozzle has a sufficient cross-sectional reduction compared to the water inlet, so that there forms a sharp, significantly increased in pressure jet.
  • This sharp jet now leaves the nozzle, bridges the free jet and hits a receiving, the free jet on the other hand delimiting nozzle, from where the jet in the downstream Line, which in turn has significantly larger cross section, flows. Since, as already described in the introduction, there is no increased backpressure which would lead to a water return, the sharp water jet can be stably maintained during the entire shower operation or can bridge the free jet path. Any leakage water accumulates, if at all, only minimally, since due to the nozzle configuration the jet can be guided very sharply and stably over the free jet route. Should leakage water still occur, it can be removed via the drain opening and directed into the WC body.
  • the drain opening is expediently directed at least in sections, preferably completely vertically downwards, so that the leakage water can ultimately drain out of the cavity automatically.
  • the water can drip from the drain opening to a channel section provided below the same, which in turn leads into the toilet body.
  • This channel section may be formed on a housing component of a shower device containing, placed on the toilet body or a toilet seat housing. If a hot air blower is provided on the housing side, which blows warm air for drying after the shower has been cleaned, then a duct section can be provided on this housing section, via which this hot air is selectively blown, whereby this duct section can then be used simultaneously for the removal of the dripping leakage water.
  • a blower is also provided, which is connected to the distributor component and serves for the air enrichment of the water coming from the injector.
  • This fan is air in blown the heated water in the manifold component, so that it is enriched with air and accordingly "voluminous" exits the downstream shower rod.
  • the blown-off water also serves to accelerate the water jet, so that the discharge pressure can be increased somewhat over this.
  • a switching device can be provided on the distributor components, via which the water can be fed to at least two separate lines, the two lines serving different shower devices of the shower rod.
  • the two lines serving different shower devices of the shower rod.
  • the shower rod for example, a buttocks shower and a so-called “lady shower” may be provided, the dispensing nozzles are positioned differently. Depending on which of the dispensing nozzles is now required, the water can be distributed over the switching device according to the associated line.
  • the valve 1 is preferably a solenoid valve with pressure control, which can be switched accordingly and allows the water to flow over a defined pressure.
  • a water heater 3 Downstream of the valve 1 is a water heater 3.
  • the flowing from the valve 1 cold water is heated in the water heater 3 to a comfortable temperature. This is done in a conventional manner alone during the run, any reservoir or tank or the like is not required.
  • the instantaneous water heater 3 comprises a corresponding heating device which is electrically operated, wherein the individual connections etc. of the continuous flow heater 3, as well as of course also other components to be supplied (eg valve 1), are not shown in detail.
  • This injector 4 is the component in which the free jet section is integrated, which is to be installed for safety reasons. The exact structure of the injector will be discussed below Fig. 2 still received.
  • a manifold component 5 which is a simple distribution valve, which can also be controlled electronically.
  • manifold component 5 has a first input connection 6, to which the line coming from the injector 4 is connected.
  • three separate output terminals are provided, to which corresponding separate lines can be connected.
  • the output terminal 7 is connected in the example shown to an input terminal 8, which is guided on a holder 9, on or in which the shower rod 10 is movably received. Over this water for basic cleaning or flushing of the shower rod 10 can be supplied.
  • the outlet connection 11 is connected via a line to an inlet connection 12 of the shower rod 10, which leads to the outlet nozzles of a buttock shower.
  • the output terminal 13 in turn is connected to an input terminal 14 of the shower rod 10, which leads to the outlet nozzles of a lady shower.
  • the individual output terminals 7, 11 and 13 can be operated by appropriate control of the distributor component 5, so the integrated valve.
  • a fan 15 which is connected via a line to an input terminal 16 of the distributor component 5. Through this fan 15, air can be blown into the hot water supplied to the outlet port 13 to enrich the water with air. This makes it possible to make the water more sparkling or more voluminous, at the same time the water can also be accelerated and consequently the pressure thereby increased.
  • the shower rod 10 is received as described in the holder 9 and is slidable via a not shown in detail moving means such as an electric motor or the like along the bracket 9. It can therefore be retracted or extended.
  • a housing 17 which is arranged in the mounting position, for example on a toilet lid 18 of the toilet 19, which includes a toilet body 20.
  • the housing 17 has one or more access openings, in Fig. 3
  • a front wall element is dismantled.
  • the shower rod 10 extended here protrudes into the WC body 20. This will be discussed in more detail below.
  • the central component is the injector 4, which in a schematic representation in Fig. 2 is shown. It comprises a housing 21, for example a hollow-cylindrical plastic housing, which has an inlet connection 22 for the heated water coming from the flow heater 3. Downstream of it is a first nozzle 23, which is clearly narrower in diameter than the housing area lying in front of it. It comes here so in terms of the water flowing through to a considerable pressure build-up. Downstream of the nozzle 23 is an open-air section or free-jet section 24, which bridges the sufficiently sharp and stable water jet 25 emitted by the nozzle 23. The length of this free jet section 24, defined or limited between the nozzle 23 and the nozzle 26, which retrieves the jet 25, is at least twenty millimeters.
  • the nozzle 26 receives as described the beam 25, it is slightly wider in diameter than the nozzle 23 and thus the jet, but may also be the same diameter. From there, the water in turn passes to an outlet port 27, to which the line, which then leads to the inlet port 6 of the distributor element 5, is connected. The diameter in this area is again significantly larger, so that there is a pressure reduction.
  • a drain opening 28 is further provided, via which any leak in the cavity 29, which ultimately forms or includes the free jet section 24, accumulating leakage water can flow.
  • the leakage water accumulates only in a minimal amount, after a sufficiently stable free jet 25 can be generated via the nozzle design. Any water can accumulate there only at the time of construction of the beam 25 respectively at the moment of collapse of the water jet 25 there. In any case, it is immediately passed through the drain opening 28 from this area.
  • the inner wall of the injector 4 may be provided in the region of the cavity 29 with a water-repellent coating.
  • the two valves 23 and 26 are preferably designed as a one-piece structural unit, for example as a plastic component which can be pushed into the housing 21 and which can be inserted via an access opening 30 which is closed by a sealing plug 31.
  • a corresponding opening is provided on the unit, which is congruent with the drain opening 28 so that leakage water can drain.
  • the nozzle 23, which as described acts as an injection nozzle, upstream may be a ball valve, this in turn may be upstream of a flow restrictor, both components are not shown in detail. If they are provided, they can all be installed in this embodiment of the injector 5 with an inserted unit.
  • Fig. 3 finally shows the toilet 19 according to the invention with the attached shower device 32.
  • the valve 1 the water heater 3, the injector 4, the manifold component 5, the fan 15 and the shower rod 10th
  • the injector 4 is installed in a horizontal orientation. He is directed so that the access opening 30 is directed to the side wall of the housing 17. Since at least a part of or in the side wall can be removed to open an access opening into the housing interior, it is easily possible to get to the injector respectively its service opening and, if necessary, take the injector if this should be be damaged or clean.
  • the drain opening 28 is down directed. Below the drain opening 28, a channel portion 33 is provided which is formed on the housing member 34, which forms the housing bottom, as it were.
  • the channel portion 33 runs apparent in the toilet body 20, ie, that the dripping from the drain opening 28 leakage water is passed directly into the toilet body, so it flows over the ceramic upper edge of the toilet body 20.
  • This channel portion 33 can simultaneously Supply channel for warm air, which is generated and discharged via a hot air blower 35 shown here only by way of example, be. This hot air is used for drying after showering.
