Definitions

  • the invention relates to a device for suction of liquid and drainage mass from the funnel-shaped Bowl of a vacuum toilet with a funnel, the one below via an outlet area into one Vacuum source connectable and lockable from the funnel Suction line passes over.
  • the present invention addresses the problem that Aspiration process of liquid and / or drainage mass from the Bowl of a vacuum toilet so that the Noise pollution is minimal.
  • the bowl is also in the Outlet area is bowl-shaped, i.e. in this In the area, the wall parts have a relatively low slope to the horizontal.
  • the result is a relatively low level of Liquid level before the suction process, so that on the ground a breakthrough in vacuum and not just that Liquid is sucked in but a mixture of water and air gets into the suction line. The consequence of this are clearly audible gurgling noises.
  • the lower area is the Bowl shaped funnel-shaped, with respect to the the user forward extension of this funnel is formed relatively flat to the horizontal, while the opposite limitation to the rear of the Funnel has a steep orientation to the horizontal. Also a breakthrough can occur here during the suction process.
  • the noises associated with suction can be as Slurping noises are classified.
  • the bowl or funnel-shaped outlet achieves that when suctioning no Breakthrough from the suction line under vacuum to Ambient air above the filling in the bowl can. This is then connected to a practically noiseless one The bowl can be emptied.
  • the principle of the present invention is based on the fact that by the design of the bowl or funnel and of the subsequent pipe part a liquid column with a ensured such a height before the start of the suction process that is large enough that the attacking vacuum Liquid filling in the form of a self-contained Graft pulls in without breaking through. This Effect is given by the details specified in the claim Features optimized.
  • the bowl goes into a funnel-shaped at the bottom Area 10 over.
  • the funnel has a funnel angle ⁇ of approximately 90 °
  • the funnel axis is not perpendicular aligned rather something towards the user inclined, namely by the angle ⁇ , which is in the range of 10 °. In this way you get a funnel-shaped area 10, not much towards the front is less inclined than towards the rear, a characteristic that known vacuum toilets with a funnel-shaped outlet are not is realized.
  • a tube piece 11 is connected to the funnel-shaped area which has a length in the axial direction of 1 and a Has a diameter of D.
  • the diameter is in Range between 35 and 40 mm and is preferably then the length l be about 10 mm, i.e. in the Of the order of 1/4 of the diameter.
  • a pipe bend 12 connects below the pipe section 11, which is roughly horizontal in a suction line 13 transforms.
  • a shut-off valve is not shown in the Suction line.
  • the effect of the suction vacuum is through an arrow in Fig. 1 is shown schematically.
  • Fig. 3 shows the situation shortly before the end of Suction process and also here it can be seen that the Drainage mass and the liquid the suction pipe 13, the Fill pipe elbow 12 and also the pipe section 11 without gas bubbles can form there.
