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 AI describes a system for vehicle construction in which a suction container is evacuated. Lines are then opened or closed by means of valves in order to use compressed air to request the facal into the collecting container.
- This system has the advantage over the known drain system according to DE-OS 39 32 893 that only a relatively small suction container has to be placed under negative pressure, but has the disadvantage that all pipe connections and the valves have to be carried out vacuum-tight and thus only one complex technical implementation is possible.
- the object of the invention is to enable a conventional toilet bowl to be converted to suction with simple means.
- a conventional toilet bowl usually a sink
- an insert connected to a suction device can be converted to suction with the advantage of saving water.
- the retrofitting can preferably be carried out with existing toilet bowls, but it is also possible to retrofit with newly installed toilet facilities.
- Two or more toilet bowls can also be connected to the suction unit, but each toilet bowl is always suctioned off individually. Therefore, the volume of the suction unit can be kept small.
- the toilet system designed according to the invention is preferably used in vehicles, for example in mobile homes and caravans, but it is also possible in stationary facilities, for example in one- and two-family houses.
- a particular advantage of the system designed according to the invention is that neither the pipe connections nor the valves have to be vacuum-tight.
- suction unit is also used for odor extraction, the suction line required for fecal extraction also being used for odor extraction.
- 1 shows a toilet bowl with insert.
- FIG. 2 shows a toilet system with two toilet bowls connected to a suction unit; 3 shows the suction unit;
- Fig. 6 shows the object shown in Fig. 5 in a perpendicular thereto
- FIG. 7 shows the hose used for the hose valve arranged at the lower end of the suction unit in cross-section;
- Fig. 8 shows the object shown in Fig. 7 in a side view.
- 1 shows a conventional toilet bowl 10, which is designed as a wash basin.
- an insert l is introduced for conversion to suction, the dimensions of which are adapted to the dimensions of the toilet bowl 10.
- the flushing valve 3 is pressurized with pressurized water.
- the pressurized water comes from the domestic water network, otherwise from a water tank with a connected pressure generator.
- an odor trap 6 which is designed here in the form of the siphon which is customary for this purpose.
- the suction-side end of the siphon is connected to a suction line 6, the other end of which is to be described with a suction unit
- the suction unit 14 is connected (Fig. 2).
- the suction unit 14 has a floor drain
- the retrofitted toilet bowl 10 is also provided with means for odor extraction.
- the odor extraction takes place via an odor extraction line 9, one end of which is connected to the upper end of the insert 1 and the other end of which is connected to the extraction line of the odor trap 6.
- the various units and valves are actuated by a controller 13, which comes into operation by moving an actuating element 8. 2 shows that two toilet bowls 10 are connected to a suction unit 14. For this constellation, the suction line 5 is branched via a control valve 11 in such a way that only one toilet bowl 10 is ever 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 there is a blower 17, the suction side of which is connected to the suction container 16, into which the suction line 5 merges.
- the hose valve 19 is closed in such a way that the pressure side of the blower 17 is connected to two exhaust air lines 18, the mouths of which are directed radially opposite one another onto the hose 23 forming the hose valve 19.
- the hose 23 is easily deformable in the radial direction and is compressed by the exhaust air flow emerging from the exhaust air lines 18 in connection with the negative pressure occurring in the suction container 16, so that the hose valve 19 is closed.
- the floor drain 15 is normally open
- a valve 4 which ensures that at low suction power of the blower 17, a connection between the suction line 5 and the odor suction line 9 is made, while this valve 4 is closed with stronger suction power, namely when suctioning the toilet contents
- a closure body 22 is arranged in a housing 21, which is raised somewhat when the suction power is low and thereby connects the odor suction line 9 to the suction line 5, while when the suction power is stronger the closure body 22 is in its upper one Closing position arrives so that no odor extraction takes place during the evacuation of the insert l.
- FIG. 5 and 6 show a mechanically acting odor trap which can be used as an alternative to a siphon.
- This odor trap has a housing 24 which is interposed in the suction line 5 and is also connected to the odor suction line 9.
- a rotary slide valve 25 provided with a cutout 27, the suction line 5 can optionally be released or the section of the suction line 5 on the suction side can be operatively connected to the odor suction line 9.
- both the suction line 5 and the odor suction line 9 are closed.
- the rotary valve 25 is mounted in the housing 24 and can be actuated by an actuator, this actuation being caused by the controller 13.
- the hose 23 arranged in the floor drain 15 and forming the hose valve 19 is provided with stiffening ribs 26 for longitudinal stiffening.
- stiffening ribs 26 for longitudinal stiffening. The desired easy deformability in the radial direction is not impaired by these ribs.
- the blower 17 When the actuating element 8 is actuated, the blower 17 sucks air out of the suction container 16 and the suction line 5. The resulting exhaust air flow is directed in a radial direction via the exhaust air lines 18 to the hose valve 19 from two sides. This exhaust air flow and the negative pressure due to the suction of the air from the suction container 16 cause the hose valve 19 to close.
- the odor extraction now takes place at a reduced speed of the fan 17.
- the reduced speed can be changed by a component in the controller 13 and adapted to the length of the suction line 5 and the system arrangement. After a time programmed in the controller 13 or after actuating the actuating element 8 again, the speed of the fan 17 is increased to the full speed with a soft start circuit.
- the contents of the insert 1 are now sucked into the suction container 16 after the valve 4 has been closed.
- the gas separator 20 prevents the suction material from getting into the blower 17.
- the control pulse to increase the speed of the fan 17 also causes the flushing valve 3 to be opened for flushing the insert 1.
- the water from the existing pressurized water network passes through the flushing valve 3 into the flushing nozzles 7 and is sprayed through this into the insert 1 in order to close it clean.
- the duration of the suction process is regulated by the controller 13 and can be adapted to the system structure during assembly.
- the duration of the rinsing process is also regulated by the controller 13.
- the pressure-flushing valve remains open for a short time in order to ensure that the odor trap 6, for example the siphon, is again filled with water.
- the suction material located in the suction container 16 after the suction can now flow into a collecting container 12 or into the sewage system after the hose valve 19 has automatically opened in the floor drain 15.
