Definitions

  • the invention relates to a toilet comprising a shell with a separation of the liquid substances, in particular urine, from all the substances supplied to the toilet.
  • the liquid substances are wholly or partially collected separately.
  • separation toilets In the case of separation toilets, the task is to largely separate faeces, in particular faeces and urine, and possibly the flushing water, so that hygiene is optimized and the individual components can be further processed independently of one another if necessary. Especially in countries of the Global South, the disposal of human excretions is a major environmental problem and pollutes the soil and water. Separating toilets make it easier to ensure hygienic and low-odour storage and further use of the excrements without the need for a complex sewerage and sewage treatment plant system.
  • Separating toilets are usually systems that have a main drain for faeces and a secondary drain for urine, with both drains usually being arranged at the respective outlet areas of a shell and the shell correspondingly having a partition or a central web to separate the two areas from each other to separate.
  • the toilets are usually designed as dry-diverting toilets and usually do not have a water connection or flushing water. Rinse water would result in amounts of sewage mixed with feces, which is problematic and undesirable. Since no flushing process is provided after the toilet has been used, dirt adhering to the toilet, in particular faeces, is not automatically removed and the toilet becomes continuously dirty. This reduces the acceptance of the separation toilet, worsens the hygiene conditions and increases the cleaning effort.
  • Another separation toilet is in the patent WO2019178622 documented from 2019. It shows an invention that can be traced back to the ceramic manufacturer LAUFEN, Eawag, EOOS and a grant from the Bill & Melinda Gates Foundation.
  • This is a urine-diverting toilet that separates urine according to the “teapot principle”.
  • the urine which due to anatomy occurs in a different area of the sitting toilet than the faeces, is guided over a surface in such a way that it is drained by surface tension in a vertical area of the toilet side wall via gravity into a separate pipe system .
  • the toilet itself is designed as a flush toilet.
  • the area with the faeces is rinsed and cleaned with a rinsing agent, preferably water, and the resulting waste water is discharged via gravity via the connected pipe system.
  • a rinsing agent preferably water
  • the separately collected urine is also discharged via a pipe system. It should be noted that this solution produces waste water, preferably a mixture of faeces and water, and the urine is discharged separately via its own gravity line.
  • patent CN 202164693 U from China describes a urine-diverting toilet. There is a separate odor trap and a drain for the faeces at the rear of the bowl. The urine separated in the front area is returned to the faeces drain inside the toilet behind the odor trap and drained away by gravity. The toilet has a water flush.
  • Vacuum toilets have the advantage that they usually require less flushing water than conventional flushing toilets.
  • the water consumption per flush is usually 0.7 to 1.5 liters.
  • the faeces, especially urine and faeces remain in a more concentrated form in vacuum toilets, which leads to advantages with regard to the required storage and transport volume, the material value and the possible further use.
  • a corresponding vacuum toilet is in the patent EP3129560 described in 2015. It is a registration of EVAC GmbH.
  • a vacuum toilet with a complex valve control and an intermediate container in the toilet is described. After the faeces, especially faeces and urine, have been suctioned off, together with the rinsing water, the waste water is fed into an intermediate vacuum tank and then fed to another gravity drainage system. It is not a separate toilet and faeces, preferably urine and faeces, are neither collected nor discharged separately. It is also not a technology that dispenses with the use of an external flushing agent, preferably water.
  • a waterless vacuum toilet system for an airplane includes a toilet bowl connected to a waste collection tank via a suction valve and a waste collection tube. Adhesion of faeces in the toilet bowl should be limited by a smooth surface and special air currents. In practice, such toilets do tend to build up. A cleaning of the resulting adhesions is not intended to be automated. This solution requires a lot of manual cleaning. This is not a separation toilet.
  • the EP 1 840 282 A2 describes a sewage system with a sewage tank, a sewage line connected to the sewage tank via an outlet valve, vacuum generating means for generating a vacuum in the sewage line, and a control mechanism for controlling the outlet valve.
  • the EP 1 013 838 A1 discloses a vacuum sewage system comprising a sanitary unit for periodic emptying cycles, a first sewer pipe connected to the sanitary facility via a normally closed first sewer valve, means for creating a vacuum in the first sewer pipe, and means for subsequently actuating the first sewer valve to cause vacuum-induced waste transport from the To allow sanitary facility through the first sewer pipe, for example to a collection tank, a municipal sewer or the like.
  • a vacuum toilet for a vehicle is also known, wherein an intermediate tank is arranged between an outlet valve and a waste water valve.
  • the object of the present invention to create a toilet which makes it possible to largely dispense with externally supplied flushing agent, in particular water, and at the same time to be advantageous in the transport and further treatment of the faeces.
  • the invention should be usable as a dry, compost or vacuum toilet. It can also be used as a flush toilet.
  • the toilet should be just as usable as a conventional toilet and allow easy cleaning.
  • this object is achieved in that urine and faeces are initially collected in separate areas in the mussel.
  • the respective catchment area can result from the anatomical arrangement when sitting on the shell.
  • Part or all of the urine can be drained into a separate volume in the mussel.
  • the urine drain can be arranged with or without an odor trap between the inside of the shell and this separate volume.
  • the flow rate during urine delivery is within a manageable range due to the amount of liquid and the height of fall when urinating.
  • the factor to be selected by the person skilled in the art is therefore the choice of the appropriate geometry of the bowl and the position of the entrance opening of the additional volume in order to achieve an effective diversion of the urine flow.
  • the inlet opening is below the upper edge of the shell and above an odor trap that is usually provided for the main drainage, which means that it is also easy to clean and can be used with a large number of different types of toilets and sewer connections.
  • the entrance opening to the additional volume can be arranged centrally in the front area. This is the predominant position for squat toilets or sit toilets, where all users are positioned in the same way.
  • the urine flows over the front area of the mussel in the direction of the pipe section and thus also over that inlet opening to the additional volume, as a result of which the urine is guided into the inlet opening.
  • Children who use a conventional sit-in toilet tend to sit at the front edge of the shell, which is why urine is also drained correctly here, while the faeces can also flow correctly into the main drain in this sitting position.
  • the toilet can be connected to a vacuum suction line.
  • a vacuum suction line can be connected to an intermediate storage tank with a vacuum pump.
  • the vacuum pump can be controlled by the user to trigger the flushing process.
  • the extraction can take place via the main discharge.
  • Other advantages of vacuum suction are that the line cross-sections can be selected to be small and the material to be conveyed is largely homogenized or broken up into small pieces during suction. This minimizes the risk of blockages in the suction system.
  • the air flow generated during the rinsing process can be used to dry and also clean surfaces in the mussel. If the user sits on the shell during the rinsing process, the air flow can be guided in such a way that drying and even cleaning of the intimate area can also be possible.
  • a further feature of the present invention is that the flushing process of the toilet can be carried out in whole or in part without additional flushing agent supplied from the outside.
  • Treated urine can be used as a flushing agent.
  • the flushing agent can be sucked out of the separate volume in the course of a flushing process by means of negative pressure and introduced into the shell.
  • a detergent pump can also be used to supply the detergent in a targeted manner.
  • this toilet can be located largely independently of the location of the municipal sewer. This is a common problem, especially when installing toilets in the basement below the backflow level of the existing sewer, and classic flush toilets cannot be drained by gravity.
  • the toilet according to the present invention can be a problem-solver and can be used in this case as well. If the toilet is located below the backflow level, the substances, preferably urine and faeces, are conveyed through the suction line several meters above the critical backflow level during the flushing process, are largely crushed and then fed to the intermediate storage facility or the municipal sewage system. In this case, an additional, high-maintenance sewage lifting system is no longer required.
  • a further feature of the invention is that a self-priming pump for sucking out the contents of the toilet can optionally be integrated directly into the suction line while still inside the toilet.
  • This pump can suck in the contents of the toilet, break it up and then pump it out of the toilet via a line with excess pressure.
  • a container to hold the contents of the toilet to be arranged directly behind or in the toilet.
  • This can also be a flexible, airtight and liquid-tight bag (bag-in-box solution). This is particularly advantageous for mobile toilet applications (e.g. camping/caravan/construction site/event/care/hospital), since any external toilet connections can then be dispensed with.
  • the power supply to the toilet to supply the aggregates can be provided by an integrated battery / power storage.
  • a water connection can be completely dispensed with.
  • the installation effort is reduced accordingly and there is more flexibility in arranging the toilet.
  • the average drinking water consumption for flush toilets in Germany is almost 13,000 liters per person per year.
  • the water required is taken from the natural water cycle, treated and then contaminated with faeces in the toilet. After being used in the flushing toilet, it has to be laboriously cleaned again in sewage treatment plants. Around 3% of global energy consumption is used for water treatment alone.
  • the use of toilets according to the present invention conserves valuable water resources and at the same time facilitates the further utilization of the materials or waste produced. These wastes, or rather resources, can consist of pure faeces, preferably urine and faeces, and in small volumes if necessary be stored. The transport effort for further processing is also minimized, since these resources are not mixed with an additional detergent.
  • the suction line does not contain a negative pressure or vacuum.
  • the suction line can be designed in such a way that it functions as a classic gravity drainage line for a certain period of time and is only used as a suction line when required. This can be particularly useful if no faeces are produced when you go to the toilet. In this way, urine and toilet paper can be removed in an energy-efficient manner without consuming electricity or temporarily stored in the toilet along with the connected pipe network. Furthermore, in this operating mode, the noise development, especially when going to the toilet at night, can be minimized.
  • An alternative embodiment provides for flushing with vacuum suction only during maintenance, periodic cleaning or inspection of the toilet.
  • the pipes can be cleaned of possible deposits due to the higher flow speeds.
  • the toilet Before and after the suction operation, the toilet can be emptied via the pipework using the classic principle of gravity.
  • the flushing process can be triggered with the toilet lid closed and closing largely tightly, or also while sitting on the toilet.
  • the invention and a possible optimized flushing process largely prevent the formation and distribution of potentially dangerous aerosols in the installation room.
  • a negative pressure is generated by the suction line, which continues into the shell of the toilet.
  • the negative pressure can also act on the additional volume with the urine, the urine reservoir, and thus lead to the main discharge being flushed with urine as a flushing agent.
  • the flushing agent can flow via the pipeline between the urine reservoir and the main line.
  • the pressure equalization for the urine reservoir can take place from the room in which the toilet is installed or from outside.
  • a line, the flushing line, between the urine reservoir and the main drain can be designed in such a way that the line is routed from above into the urine reservoir and far down there. This allows the whole available when needed stagnant volume for toilet flushing or the subsequent filling of the odor trap, for example a siphon, can be used in the main drain. This function is based on the physical principle of "communicating tubes".
  • the second line between the urine storage and the main drain can be provided as an overflow in the upper area of the urine storage. This line can prevent liquid from backing up in the urine reservoir or unintentional emptying of the urine reservoir via the flushing line into the main drain.
  • the urine reservoir can also be designed as a flexible sack (bag-in-box solution) and then seals the urine airtight.
  • bag-in-box solution bag-in-box solution
  • This construction offers advantages in the process of urine preparation and stabilization.
  • Another advantageous feature is that the urine can be stored in the urine reservoir without significant contamination with other substances, particularly water. This means that deposits such as urine scale cannot form so easily and the risk of clogging can be significantly reduced.
  • vacuum toilets that use water as the flushing agent have major problems in practice, which can lead to increased maintenance costs.
  • the urine can come into contact with a preservative and optionally also a coloring agent during discharge into the urine storage tank or afterwards directly in the urine storage tank, which means that the urine does not develop any undesirable odors during later storage and optionally has a defined color, for example BLUE, during the rinsing process and use as a rinsing agent.
  • a preservative and optionally also a coloring agent during discharge into the urine storage tank or afterwards directly in the urine storage tank, which means that the urine does not develop any undesirable odors during later storage and optionally has a defined color, for example BLUE, during the rinsing process and use as a rinsing agent.
  • Contact with the preservative and optionally the dye can take place in such a way that the fresh urine is passed over this agent, for example in solid form, when it is separated and can mix with it in such a way that the urine is preserved and optionally also dyed.
  • the toilet can have a flushing arrangement which is designed in such a way that solid components of the faeces, preferably faeces, are flushed away by the urine from the urine reservoir in the area of the main drain.
  • a flushing arrangement which is designed in such a way that solid components of the faeces, preferably faeces, are flushed away by the urine from the urine reservoir in the area of the main drain.
  • the rinsing arrangement can be constructed in such a way that, for cleaning the area on the inner surface of the seat shell, a nozzle or another constructive outlet optimizes the cleaning by the urine.
  • the flushing process of the toilet is triggered by closing the toilet lid.
  • the suction system or the self-priming pump installed directly in the toilet is activated by a contact.
  • the construction with a closed toilet lid ensures that the pressure equalization takes place in a defined manner via the urine storage and/or an optimal cleaning and drying of the inside of the mussel takes place via an air flow. Furthermore, a whirling up of aerosols during the flushing process and a transfer to the user can be prevented even further.
  • the main drain in the lower area of the shell is designed in such a way that it forms an odor trap, in particular a siphon.
  • the odor trap in the main line of the toilet can also be designed as a mechanically controllable closure, in particular a controlled valve or stopcock. This is particularly so in larger objects useful where several toilets are connected to one suction line.
  • a self-priming pump directly in the suction line inside the toilet can also serve as an odor trap.
  • the rinsing arrangement is such that an additional rinsing agent, in particular water, can also be supplied.
  • an additional rinsing agent in particular water
  • the level in the urine reservoir is not sufficient for the rinsing process and in this case an additional rinsing agent can be added.
  • the toilet has a disposal device which is suitable for disposing of the urine, the faeces or a mixture of both under a certain condition, bypassing the regularly provided suction line.
  • a disposal device which is suitable for disposing of the urine, the faeces or a mixture of both under a certain condition, bypassing the regularly provided suction line.
  • the sucked substances are stored in one or more collection containers.
  • This collection container will usually be outside the room in which the toilet is installed and, if possible, in the basement or even outside the building. The substances can then be periodically removed from this container and sent for further recycling.
  • standardized containers for example plastic barrels, bag-in-box sacks or IBC tanks. These can then serve as exchange containers or a collection system will be introduced.
  • the substances sucked out of the toilet to be fed into the communal drainage system, mostly alluvial sewers, in whole or in part according to specified conditions. In this case, the collection container mentioned can be omitted and there is no additional effort.
  • the toilet can be designed to be mounted in place of a conventional floor standing or wall mounted flush toilet.
  • the connection line of the toilet can be routed through the existing waste water pipe of the previous flush toilet, if necessary to the vacuum pump and if necessary to the intermediate storage (pipe-in-pipe).
  • Conventional toilet drain pipes have a diameter of 80-110mm.
  • the connecting pipe of the toilet usually has a diameter of 40-50mm.
  • the existing sewage pipes can continue to be used for gray water (waste water without faeces) if the toilet connection pipe is laid in this pipe. This makes it possible to convert existing buildings to the toilet according to the invention.
  • a vacuum pump for example a suction turbine
  • This vacuum pump can be activated by the user, for example, when the toilet needs to be flushed. In this case, a negative pressure is created in the collection container and continues to the toilet, where the flushing process can take place.
