Definitions

  • the invention relates to a toilet system with vacuum suction.
  • Vacuum toilets have been known for a long time and are in use.
  • DE 41 36 931 A1 describes a system for vehicle construction, in which a Suction container is evacuated. Then lines are made using valves opened or closed to place the fecal into the collection container using compressed air to promote.
  • This plant has compared to the known Drain system according to DE 39 32 893 A1 the advantage that only one relative small suction container must be placed under negative pressure, but has the Disadvantage that all pipe connections and the valves are vacuum-tight must be carried out and thus only a complex technical implementation is possible.
  • the invention has for its object a simple means To convert a conventional toilet bowl to suction.
  • a conventional toilet bowl usually a sink
  • an insert connected to a suction device can be converted to suction with the advantage of Water saving
  • the conversion can preferably be done with existing toilet bowls, but it is also possible. to convert in newly installed toilet facilities.
  • Two or more toilet bowls can also be connected to the suction unit but each toilet bowl is always vacuumed individually. Therefore, the volume of the suction unit can be kept small become.
  • the suction unit to operate a blower and also for the Control an electrical connection must be available, it offers that Toilet bowl with comfort facilities such as heating, lighting, Provide sound with music and the like.
  • the toilet system designed according to the invention is preferably used in vehicles, e.g. in campers and trailers, he is but also in stationary facilities, e.g. in one and two family houses, possible.
  • suction unit is also used for odor extraction is used, the necessary for the faecal suction Suction line is also used for odor extraction.
  • FIG. 1 shows a conventional toilet bowl 10, which acts as a washdown sink is trained.
  • the toilet bowl 10 is up for retrofitting Suction an insert 1 introduced, the dimensions of which to the Dimensions of the toilet bowl 10 is adjusted.
  • the insert 1, the one with is provided with a non-stick coating, lies over flanges on the upper one Edge of the toilet bowl 10 on.
  • flushing nozzles 7 there are flushing nozzles 7 near the top of the insert a flush line 2 are connected to a flush valve 3.
  • the flush valve 3 is pressurized with water.
  • the pressurized water comes from one Use in a building from the domestic water network, otherwise from a water tank with connected pressure generator.
  • odor trap 6 which is designed here in the form of the siphon customary for this purpose.
  • the suction-side end of the siphon is connected to a suction line 5, the other end with a suction unit to be described 14 is connected (Fig. 2).
  • the suction unit 14 has a floor drain 15, via which the suction unit 14 can be emptied into a collecting container 12 is.
  • the retrofitted toilet bowl 10 is also equipped with means for odor extraction Mistake.
  • the odor extraction takes place via an odor extraction line 9. one end of the top of the insert 1 and the other End is connected to the suction line of the odor trap 6.
  • the various units and valves are controlled by a controller 13 actuated. which comes into operation by moving an actuating element 8.
  • Fig. 2 it is shown that two toilet bowls 10 to a suction unit 14 are connected.
  • the suction line 5 is over a control valve 11 branches in such a way that only one toilet bowl 10 is evacuated.
  • a suction unit 14 In Fig. 3, the structure of a suction unit 14 is shown schematically. This has a suction container 16, at the upper end of which Blower 17 is located, the suction side of which is connected to the suction container 16 is, in which the suction line 5 opens.
  • a floor drain 15 At the lower end of the suction container 16 there is a floor drain 15, which can be closed by a hose valve 19.
  • the closing of the hose valve 19 takes place in such a way that the pressure side of the fan 17 is connected to two exhaust air lines 18, the Mouths opposite one another radially on the hose valve 19 forming hose 23 are directed.
  • the hose 23 is in the radial direction easily deformable and is by the from the exhaust air lines 18th Exhaust air flow in connection with that in the suction container 16 occurring vacuum compressed so that the hose valve 19th is closed.
  • the floor drain 15 is normally open.
  • a valve 4 is shown, which ensures that at low Suction power of the blower 17 a connection between the suction line 5 and the odor extraction line 9 is produced while this valve 4 with stronger suction power, namely when vacuuming the toilet ingredients, is closed.
  • a closure body is in a housing 21 22 arranged, which is slightly raised at low suction power and thereby connects the odor suction line 9 to the suction line 5, while with stronger suction power the closure body 22 in its upper Closing position arrives, so that during the evacuation of the insert 1 no odor extraction takes place.
  • a mechanically acting odor trap is shown, which can be used as an alternative to a siphon.
  • That odor trap has a housing 24 which is interposed in the suction line 5 is and also connected to the odor suction line 9 is.
  • a rotary valve provided with a cutout 27 25
  • the suction line 5 can either be released or the suction side Section of the suction line 5 effectively with the odor suction line 9 are connected.
  • both the Suction line 5 and the odor suction line 9 closed.
  • the rotary valve 25 is mounted in the housing 24 and can by an actuator are operated, this actuation caused by the controller 13 becomes.
  • the fan 17 When actuating the actuating element 8, the fan 17 sucks out air the suction container 16 and the suction line 5.
  • the resultant Exhaust air flow is via the exhaust pipes 18 in the radial direction of two Pages passed to the hose valve 19.
  • the odor extraction now takes place at reduced fan speed 17.
  • the reduced speed can changed by a component in the controller 13 and the length of the Suction line 5 and the system arrangement can be adapted.
  • the speed of the fan 17 with a soft start circuit increased to full speed. Now the content of the Insert 1 sucked into the suction container 16 after the valve 4 is closed has been.
  • the gas separator 20 prevents the suction material in the fan 17 arrives.
  • the control pulse to increase the speed of the Blower 17 simultaneously opens the flushing valve 3 for flushing of use 1.
  • the water comes from the existing pressurized water network through the flushing valve 3 into the flushing nozzles 7 and through this into the Insert 1 sprayed to clean it.
  • the duration of the suction process is regulated by the controller 13 and can be used to assemble the system be adjusted.
  • the duration of the rinsing process is also regulated by the controller 13.
  • the pressure flush valve remains open for a short time to reach that the odor trap 6, for example the siphon, again with water is filled.
  • the one located in the suction container 16 after the suction Suction material can now be opened after the hose valve 19 has opened independently in the bottom drain 15 into a collecting container 12 or into the sewage system flow away.
