Description

TOILET SYSTEM WITH VACUUM EXTRACTION DESCRIPTION OF THE INVENTION The invention relates to a toilet system with vacuum suction. In conventional toilet systems, water is used as a means of transport for faeces. There is no separation of water and beams. A large amount of water is required, this being undesirable for reasons: ecological and economic. Vacuum toilets are known and used for a long time. DE 41 369 931 A1 describes a system for use in vehicles in which an extraction tank is evacuated. Subsequently, the pipes are opened and closed by means of valves in order to transport the feces into the collection tank by means of compressed air. However, compared to known drainage systems according to DE-OS 39 32 893, this system has the advantage that it only needs a relatively small extraction tank to place it under vacuum. However, it has the disadvantage that all pipe fittings and valves must be vacuum tight and therefore, only a complex technical realization is possible.

DE 296 04 512 Ul discloses a method whereby there is a pressure equalization in e 1 of the extraction vessel after each extraction. The emptying of the extraction tank inside a stool collection tank is carried out at a pressure of zero. The aforementioned publication describes the method and its advantages, although it does not contain technical solutions for the implementation of the described method. According to the description, the system is designed for use in large buildings. Technically, the required individual extraction of the toilets is in contradiction with the field of application. On the other hand, an additional rationing is observed in the performance of a permanent color guard extraction and, on the other hand, in the emptying of the extraction tank after each extraction and after the pressure equalization. The object of the invention is to allow: through simple means a conversion of a conventional toilet bowl to suction extraction. The object of the invention is achieved through the characteristics indicated in rei indication 1.

A conversion for extraction, with the advantage of water saving, can be done in a conventional toilet bowl, usually a descending discharge cup, is provided with an insert connected to an extraction device. The conversion can preferably be carried out in the existing toilet bowls although it is also possible to convert the newly installed toilet systems. It is also possible that two or more toilet bowls are connected to the extraction unit. However, the case is always that of the individual extraction of each toilet bowl. Therefore, the size of the extraction unit can be maintained reduced. Since a fan is required for the extraction unit and therefore also an electrical connection for the control, it is obvious to provide the toilet bowl, crsn accessories such as heating, lighting, music, etc. The toilet system according to the invention is preferably for use in vehicles, for example in mobile homes and in wheelchair cabins. However, the system can also be used in stationary installations such as houses that are double or double. A special advantage of the system according to the invention is that neither the pipe connections nor the valves need to be watertight. Additional advantageous embodiments of the invention are defined in the dependent indications. It is a particular advantage, if the extraction unit is also used for extraction of the keepers, the extraction conduit required for the extraction of the feces is also used for the extraction of the guada or 1 or r. BRIEF DESCRIPTION OF THE DRAWINGS Hereinafter, an invention is described in greater detail with reference to the modalities schematically depicted in the drawings, in which: Figure 1 shows a toilet bowl with the insert; Figure 2 shows a toilet system with two toilet bowls connected to an extraction unit; Figure 3 shows the extraction unit; "Figure 4 shows a valve for the connection of an extraction conduit of the guardians, Figure 5 shows a section through a mechanically operated sunshock siphon, Figure 6 shows the subject matter presented in Figure 5 in a perpendicular section of Figure 7 shows a cross section of the hose used for the hose valve located at the lower end of the extraction unit, and Figure 8 shows a side view of the object shown in Figure 7. Figure 1 shows a conventional toilet bowl 10 in the form of a discharge cup desired n. Placed in the toilet bowl 10 for conversion to extraction is an insert 1 which is ap- proved in its dimensions to those of the toilet bowl 10. The insert 1, which is provided with a non-adhesive coating, is supported by means of flanges, on the upper edge of the toilet bowl 10. Located near the upper edge of the insert are the discharge nozzles 7 which are connected by means of a discharge pipe 2 to a discharge valve 3. The discharge valve 3 is subjected to pressurized water. If the system is used in a building, -the pressurized water comes from the main water supply; otherwise it comes from a water tank with a pressure generator connected. Located at the lower end of the insert 1 is a trap trap 6 that is in the shape of a siphon drain usually used for this purpose. The end of the extraction side of the siphon drain is connected to an extraction duct 6, the opposite end of which is connected to an extraction unit 14 which will be described later. (Figure 2). The extraction unit 14 comprises a floor drain 15 through which the extraction unit 14 can be emptied into a collecting tank 12. The converted toilet bowl 10 is also provided with means for extracting the laundry. The extraction of the sunscreens is achieved by means of a conduit 9 for extracting guardians, 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 conduit of the siphon "5. and valves are operated by a control 13 which comes into operation through the movement of an operating element 8. Figure 2 shows that two toilet bowls ^ 10 were attached to a 14 extraction unit. , the extraction duct 5 is branched by means of a control valve 11 in such a way that only one toilet bowl 10 is evacuated at the same time. - Figure 3 schematically shows the construction of a toilet unit 14. extraction. Such a suction unit 14 has an extraction tank 16 at the upper end of which a fan 17 is placed, the suction side of which is connected to the extraction tank 16 into which the extraction duct 5 is connected. Located at the lower end of the extraction tank 16 is a floor drain 15 which can be closed by a hose valve 19. The hose valve 19 is closed on the pressure side of the fan 17 which is connected to two outlet air pipes 18, the nozzles of which, (in opposition to one another) are radially directed towards the hose 23 forming the hose valve 19 The hose 23 is slightly deformable in the radial direction and is pressed by the outlet air stream, which exits from the outlet air pipes 18, together with the vacuum in the extraction tank 16, with the result that the The hose valve 19 is closed in. The floor drain 15 is normally open. ~ Figure 4 shows a valve 4 which ensures, that at a low suction power of the fan 17., a convexion is established between the extraction duct and the heat-dissolving duct 5, while, at a high suction power, ie when the content of the toilet is extracted, the valve 4 is closed. Provided for this purpose in a housing 21, there is a closure body 22 which, at a low suction power, is raised in a slight way and thus connects the duct 9 for extracting the sun-guard from the duct. 5 of extraction, while at a high suction power, the closure body 22 is in its upper-closing position, with the result that there is no extraction of the sunscreens while the insert 1 is being evacuated.

Figures 5 and 6 show a painter's siphon that is mechanically operated and can be used as an alternative to the siphon drain. This honeycomb siphon comprises a housing 24 which is inserted into the extraction duct 5 and is additionally connected to the duct for extracting the dragees. Through the rotation of a rotary disc valve 25 provided with a recess 27, the extraction duct 5 can be opened or the suction side of the extraction duct 5 can be actively connected to the douching extraction duct 9. In a third position, the extraction duct 5 and also the duct 9 for extracting the locks are closed. The rotary disk valve 25 is held in the housing 24 and can be operated by a control element, such operation being initiated by the control 13. According to Figures 7 and 8, the hose 23, which is placed in the drain 15 of floor and form the hose valve 19, is provided with longitudinal ribs 26 _of reinforcement. The slight deformation capacity desirable in the radial direction is not affected by such ribs. The operation, performed by the control 13, of the device described herein is as follows: When the operation element 8 is activated, the fan 17 sucks the air from the extraction tank 16 and the extraction duct 5. The resulting output air stream is directed by means of the outlet air passages 18 in the radial direction from two sides on the hose valve 19. The outlet air stream and the vacuum produced by the suction of the air from the extraction tank 16 cause the hose valve 19 to close. This is followed by the extraction of the reduced-speed heat registers of the fan 17. The reduced speed can be changed by a component in the control 13 and can be adapted to the length of the extraction duct 5 and to the configuration of the system. After a set time in the control 13 or after the restored operation of the operative element 8, the speed of the ventilator 17 increases up to the total velocity with a uniform ignition circuit. The contents of the insert 1 are now sucked into the extraction tank 16 after the valve 4 has been closed. The gas separator 20 ensures that the extracted matter does not fall inside the fan 17. The control pulse to increase the speed of the fan .17 simultaneously causes the discharge valve 3 to blow in order to discharge the insert 1. Water from the main pressurized water supply passes through the discharge valve 3 into the discharge nozzles 7 and it is dispersed by such nozzles 7 inside the insert 1 in order to clean the latter.The duration of the extraction process is controlled by the control 13 and can be adapted in the installation to the configuration of the system. The discharge is controlled by the control 13. After the fan 17 is turned off, the pressurized discharge valve remains open for a short period in order to ensure that the sherd, 6, for example the siphon drain, is filled with water again. After the automatic opening of the hose valve 19 in the floor drain 15, the material extracted in the extraction tank 16 can flow into a collecting tank 12 or into the pipe system.
