Definitions

  • the invention relates to a vacuum toilet, comprising a basin with flushing nozzles arranged in the upper basin area and a shut-off valve in the drain line connected in the lower basin area.
  • the rinse water will run into the pool and will not be able to drain down because the shutoff valve is closed.
  • the water level in the basin rises and can finally reach the point where the rinsing nozzles come into contact with the rinsing water in the basin, so that an undesired connection from the more or less contaminated rinsing water to the fresh water circuit can result, should a defect occur in the Fresh water system would create a suction, contaminated water from the toilet would get into the fresh water system. However, this must be excluded.
  • the safety measure used so far here would be an additional installation of a separate rinsing water circuit in addition to the fresh water circuit, that is to say a relatively cost-intensive measure.
  • the depression outside the aircraft moving at great heights being used as a means of conveying objects or body parts due to the suction effect of the vacuum People are sucked in and there is a risk of property damage and serious physical injury.
  • the invention deals with such shortcomings of known vacuum toilets and achieves an effective remedy in that in the case of a vacuum toilet of the type mentioned in the lower pool area or in the drainage area, an outwardly leading pipeline opens, which ends at a height slightly below the flushing nozzles and towards the outside is open.
  • the highest possible water level in the pool can be determined by fixing the end of this pipeline to the desired geodetic height. If the flushing nozzles supply flushing water into the basin when the valve is closed, the most glaring case that can occur is that the flushing water exits via the open end of the pipeline. Under no circumstances can the water level in the pool reach the height of the nozzles, which means that the fresh water circuit is not impaired.
  • the vacuum source acts not only on the mass in the basin but also on the liquid that is present in the pipeline.
  • the drainage mass and the liquid are attracted by means of the suction power of the vacuum, and after the pipeline has been emptied, air is sucked in, so that in Under no circumstances, for example when using the toilet without a toilet seat and conceivable complete sealing of the pool edge with the body of the person using it, such a suction effect can be generated in the pool through which body parts or objects can be attracted.
  • suitable dimensioning of this additional pipeline with regard to the inside diameter or a throttling point can result in the mass being sucked in being fluidized to a certain extent, so that overall the conditions during suctioning are more favorable.
  • 10 denotes the basin of a vacuum toilet.
  • a suction line which can be shut off by a valve 20.
  • the direction of the delivery of the drainage mass or the force effect of the vacuum is indicated by arrow 30.
  • flushing nozzles 11 In the upper part of the basin there are several flushing nozzles 11, which are arranged at a geodetic height H1 and whose meaning and purpose is known. Regulations require that these flushing nozzles 11 must not come into contact with the water collecting in the basin 10, which, as already stated, cannot be ensured in known toilets.
