Definitions

  • the invention relates to a toilet bowl with an interior, which is flushed with a water flush, in the flow direction below a filled with water up to a certain water level C oruchsverschl closes the interior, which has an opening at its opposite upper end and in which one with Extractor pipe connected to the fan for extracting odors opens.
  • Odor extractors have recently become known which suck the air out of the toilet bowl and discharge it into a ventilation shaft or return the filtered air to the toilet room.
  • the extraction takes place here at the top of the toilet bowl.
  • This method has the disadvantage that a great deal of air has to be drawn off in order to prevent odors from escaping from the toilet bowl.
  • the air extraction must completely cover the entire upper opening of the toilet bowl facing away from the odor trap. The closer they are to the upper edge of the toilet bowl, the more intense the air flow must be so that it can also spread in the direction of a horizontal plane corresponding to the opening.
  • an unnecessarily large dimensioning of a blower used for ventilation is therefore necessary.
  • the object of the present invention is therefore to improve a toilet bowl of the type mentioned in the introduction so that the escape of odors is completely prevented.
  • suction pipe opens into the lower part of the interior.
  • the air contaminated with odors can be removed evenly. Due to the usual design of a toilet bowl in the form of a funnel, the air is sucked in evenly over the entire area of the opening. As a result, fresh air that is not contaminated by odors enters the funnel and is sucked through the interior of the toilet bowl largely without turbulence. In this way, a largely uniform flow forms in the interior of the toilet bowl, which moves in the direction of the odor trap and thereby leaves no room for the air contaminated with odors to be able to exit the opening against this flow direction.
  • the suction pipe is designed as a hollow body which forms a unitary part with at least one outer wall delimiting the interior.
  • the suction pipe is already integrated into the toilet bowl during its manufacture, so that there is no reason to depart from the tried and tested shape of a toilet bowl.
  • This extensive retention of the conventional form of toilet bowls facilitates the interchangeability of the toilet bowls provided with an air extraction system with those which conventionally do not have such an air extraction system.
  • suction pipes installed in the interior do not make it difficult to keep the toilet bowl clean and use it.
  • the suction pipe ends with its end protruding into the interior below a water level forming the odor trap, which is lowered below the protruding end of the suction pipe for the purpose of extracting odors.
  • the suction pipe with its end lying outside the toilet bowl can be guided into a drain pipe without the fact that odors rising from the drain pipe can penetrate into the toilet bowl through the suction pipe.
  • an opening of the suction pipe facing the interior is exposed to water, so that the air contaminated with the odors can be sucked out through this opening.
  • a toilet bowl consists essentially of a funnel 1, an odor trap 2 and a drain nozzle 3.
  • the odor trap 2 connects in a vertical direction to the funnel 1 in the region of its lower end 4 and is formed by a manifold 5 which extends from the lower end 4 extends to the drain port 3.
  • This drain connector 3 is approximately at the level of the lower end 4. Its lower edge 6 defines the height of a water level 7, which is reached when the odor trap 2 is filled with water 8.
  • the drain connection 3 is connected on its side facing away from the funnel 1 to a drain pipe 9 which opens into a sewage system, not shown.
  • the funnel 1 is formed by walls 10 which enclose an interior 11. This interior 11 opens on its top 12 facing away from the odor trap 2 through an opening 13. Below this opening 13, a flush pipe 14 opens into the interior 11 and is connected to a water network 16 via a cistern 15.
  • a handle 17 is attached to the cistern 15 and is connected to a water valve 125 installed in the cistern 15. When this handle 17 is actuated, the water valve 125 opens, so that a quantity of water 18 accumulated in the cistern 15 enters the interior 11 from the cistern 15 through the flush pipe 14 and in this way flushes the funnel 1. Due to the amount of water 18 entering the interior 11, the water level 7 in the odor trap 2 rises, so that the water 8 enters the drain pipe 9 and is sucked out of the odor trap 2 in the direction of a sewage network (not shown).
  • the wall 10 is formed as a hollow body 19 at least in a rear region of the funnel 1 facing the drain pipe 9.
  • a suction pipe 2o opens into this hollow body 19 outside the funnel 1, in the course of which a blower 21 is installed with its suction side.
  • This blower 21 is connected on its pressure side via an exhaust pipe 22 to the drain pipe 9, into which it opens.
  • a second odor trap 23 can be provided be seen that is filled with water 24. This odor trap 23 prevents unpleasant smells from the drain pipe 9 through the suction pipe 2o into the interior 11 1.
  • the hollow body 19 extends in a washdown unit (6 0 ) along a wall forming the funnel 1.
  • the hollow body 19 can extend below a support surface 57 which extends across the interior 11 and has a bend 58 in the area of the odor trap 2 in the direction of the odor trap.
  • the opening 26 lies below the elbow 58 in a region around which the water 8 flows, between the water level 7 and a lower level 35.
  • the hollow body 19 is washed by the water 8 of the odor trap 2 when the entire odor trap 2 is filled with water 8.
  • This end 25 is provided with an obliquely cut opening 26, the lower edge 27 of which projects deeper into the water 8 of the odor trap 2 than its upper edge 28. This oblique cut ensures that air is released from the interior at an early stage when the water level 7 is lowered 11 can be sucked through the suction pipe 20 by the blower 21 before the entire opening 25 has been cleared by the water.
  • the hopper 1 rests through a support collar 29 on a floor 3 0th
  • This support collar 29 is firmly connected to the walls 1 0 and encloses the odor trap 2.
  • an intermediate space 31 is provided, in which a suction pump 32 is fastened.
  • This suction pump 32 is connected via a pressure line 33 to the drain pipe 9, into which it opens out in a possibly high area.
  • the suction pump 32 is connected via a suction line 34 to the odor trap 2, into which the suction line 34 opens, on one lower level 35, at which the water 8 with a correspondingly lowered water level 7 releases the entire opening 26 of the hollow body 19.
  • the suction pump 32 can be connected to an electrical network via an electrical line (not shown).
  • the fan which is also connected to the electrical network, so that after the water level 7 has been lowered, air enriched with odors can be sucked in from the interior 11 in the direction of the fan 21 via the hollow body 19.
  • the hollow body 19 opens below the lower end 4 into the odor trap 2.
  • the opening 26 lies in a very narrow area of the interior 11, so that due to the negative pressure generated by the blower 21, the hollow body 19 is uniform from all parts of the interior 11 the air present there flows in.
  • This air extraction which is evenly distributed over the entire interior 11, ensures that no area of the funnel 1 can smell in the direction of the opening 13.
  • the extracted air is conveyed via the drain pipe 22 into the drain pipe 9.
  • a lowering of the water level 7 to a lower level 35 can also be carried out with the aid of a water jet emerging from a mouth 86 of a pipe 36.
  • This mouth 86 lies at the level of a lower water level 85 in the odor trap 2, which is lowered to the lower level 35.
  • the mouth 86 is designed as a nozzle attached to one end 87 of the tube 36, which is directed in the direction of a trough 91, which in a Wall 129 of the odor trap 2 is formed.
  • This trough 91 is open at its upper end facing away from the wall 129. It forms a vacuum line which bundles the water jet emerging from the mouth 86 and in which a vacuum is formed which sucks the water 8 out of the odor trap 2.
  • trough 91 has a lower end 13o projecting into the odor trap 2, through which the water 3 is sucked off in the direction of the drain pipe 9.
  • the water pressure in the pipe 36 is controlled by means of a solenoid valve 46 which is connected to the water network 16.
  • a second odor trap 23 can also be provided in the exhaust pipe 22.
  • This odor trap can be in front of or behind the fan 21 in the direction of flow of the air drawn in by the fan 21.
  • this can be arranged in the course of the exhaust pipe 22 in such a way that the odor trap 23 is filled with water 59, which is sprayed towards the lower end 4 of the funnel 1 via a flushing device 44.
