Description

field of technology

According to several independent aspects, the present invention relates to a separate toilet, comprising a toilet housing, a urine collection container and a faeces collection container, the toilet housing having an outer housing side wall which borders a toilet interior, the toilet interior having an area for receiving the faeces collection container and in particular an area for receiving of the urine collection container and wherein the separation toilet has a seat. In the first aspect of the invention, the separating toilet has a toilet lid; in the further aspects of the invention this is not necessary or possible.

State of the art

Separating toilets are conventionally used in, among other things, camping vehicles, tents, boats or the like. The use is therefore often mobile. Known separating toilets are based on the functional principle that urine and feces (also referred to as stool) must be separated from each other in order to avoid, as far as possible, the unpleasant odor that would otherwise arise from mixing urine and feces bacteria. For this purpose, separation toilets have been proposed in the past, in which urine is directed into a urine collection container and faeces are directed into a faeces collection container. However, despite the separation of urine and feces in the toilet interior, certain unpleasant odors arise, such as foul gas emanating from feces. In this respect, such smells from the inside of separating toilets to the outside into the toilet room, i.e. H. into the installation room of the separation toilet, it is known to divert room air of the installation room with the unpleasant smells into the outside world. Separating toilets are also known in which odors and air from inside the toilet are led from the toilet body directly to the outside world using pipes or hoses in order to prevent odors from getting into the room where the toilet is installed. With these conventional approaches, the disadvantage is that there is a loss of heat or cold in the air in the room where the toilet is installed (also depending on the season), that there is a need for structural changes to existing toilet rooms and that, for example a densely occupied campsite can also lead to odor nuisance in the outside world or environment.

Summary of the invention

Against this background, the invention is based on the object of advantageously designing a separation toilet. In particular, it is the task that at least some, in particular as many or all, of the above-mentioned disadvantages of conventional separation toilets can be reduced or, in particular, even avoided. In particular, the aim is to reduce or, in particular, prevent odors from escaping from the separating toilet into the air in the room where the separating toilet is installed and into the outside world.

Against this background, the invention proposes a solution according to a first aspect, a separation toilet with the features mentioned at the outset, wherein at least one toilet lid passage opening is formed in the toilet lid and the separation toilet has at least one exhaust air filtering device which is in fluidic connection with the at least one toilet lid. Passage opening stands and which is connected to the toilet lid, in particular a plurality of toilet lid passage openings being formed in the toilet lid and the exhaust air filtering device being in fluid connection with the plurality of toilet lid passage openings. The invention thus advantageously provides a separation toilet which enables gases formed in its interior, in particular in the feces area, which have a bad smell to pass from the interior of the separation toilet through an exhaust air filtering device into the external environment of the separation toilet. Such a separation toilet is therefore suitable for partially or completely removing bad odors from gases formed in the interior of the toilet, such as sewage gas from the faeces area, within the separate system limits of the separation toilet by means of filtering and then releasing the filtered gases into the environment directly adjacent to the separation toilet, i.e. in particular released into the ambient air of a room in which the separation toilet is installed. It is possible that the separating toilet only releases air that has minimized or odor-free air to the outside. Reducing or eliminating odor within the separate system limits of the separating toilet means that the separating toilet is designed in such a way that no structural changes have to be made to its installation location in order to operate it and no room air and cold/heat have to be removed in order to eliminate the smell. There are therefore no requirements for the installation location, which means that the separation toilet can be used extremely flexibly. The separation toilet proposed according to the first aspect of the invention uses the effect that a large part of the gases of the typical gas mixture in separation toilets, namely digester gas from the faeces area, is lighter than the ambient air and therefore rises. When the separating toilet is installed correctly, its toilet lid is located on the top of the toilet. Due to their natural flow behavior, the gases rising inside the separating toilet, which are lighter than air, reach upwards within the separating toilet and finally through the exhaust air filtering device and then filtered through the toilet passage openings into the immediate surroundings of the separating toilet. The flow behavior caused by the different densities of the gases or air advantageously makes it possible for the proposed separation toilet to pass gases through the exhaust air filtering device not to require a fan, since the gases to be filtered are in the separation toilet at the top due to their lower gas densities compared to air arranged exhaust air filtering device inevitably flow through. One advantage of a separating toilet that does not have a fan is that no electrical power is required. Arranging the exhaust air filtering device on the toilet lid, i.e. at the top of the separating toilet, also offers the possibility that gases that rise upwards from the urine collection basin and the urine container, for example if the closure is leaky, which are lighter than air, also escape into the environment can be filtered using the exhaust air filtering device. In other words, the exhaust air filtering device can be specifically arranged directly in the flow area of the gases to be filtered by taking advantage of the density differences of the gases. The invention also makes it possible for gases that have to escape from the separation toilet due to temperature fluctuations to be inevitably guided through the exhaust air filtering device. Such temperature fluctuations occur, for example, in vehicles and in mobile cabins, for example due to sunlight, engine heat, differences between driving and stationary, especially in winter. Because the exhaust air filtering device allows gas or air to flow through the exhaust air filtering device from the separating toilet into its external environment, an air flow can also arise inside the separating toilet, depending on the conditions, through which the drying of faeces can be accelerated. In this respect, a separating toilet according to the invention can advantageously also reduce the development of odors within the separating toilet.

A possible further development is seen in that the exhaust air filtering device is attached to the inside of the toilet lid, with the exhaust air filtering device being used to create an air-permeable passage through it between a space that adjoins a plane spanned by the seat in the separating toilet and the toilet lid. Passage opening or the toilet lid passage openings is formed. It is possible that the outside of the toilet lid is exposed in an area bordering the toilet lid passage opening or the toilet lid passage openings and/or is designed to be connection-free. The toilet lid passage opening or the toilet lid passage openings is or are expediently in fluid communication with an external environment of the separation toilet. Alternatively, there is the possibility that the exhaust air filtering device is attached to the outside of the toilet lid, an air-permeable passage passing through it being formed by means of the exhaust air filtering device between the toilet lid passage opening or the toilet lid passage openings and an external environment of the separation toilet.

According to its second aspect, the invention proposes to solve the problem a separation toilet according to the features mentioned at the outset, wherein the separation toilet has a wall having an intermediate wall section, at least one intermediate wall section through-opening being formed in the intermediate wall section, the intermediate wall section and the intermediate wall section being formed. Through opening between the toilet interior and a space which adjoins a reference plane spanned by the seat in the dividing toilet, the dividing toilet having a cover by means of which the at least one intermediate wall section through opening is at least predominantly or completely covered or can be covered and in which at least a cover passage opening is formed, wherein the separation toilet has at least one exhaust air filtering device which is in fluid communication with the at least one cover passage opening and which is connected to the cover, in particular a plurality of cover passage openings being formed in the cover and the exhaust air filtering device is in fluid communication with the plurality of cover passage openings. Such a separation toilet is also suitable for partially or completely achieving the previously described effects and advantages, particularly with regard to the gases that rise upwards and thereby reach the exhaust air filtering device. It is preferred that the toilet interior is bordered at an upper region of the toilet interior by means of the intermediate wall section in relation to a use position of the partition toilet in which its seat faces upwards. Gases formed in the interior of the toilet, which are lighter than air, can rise in the separating toilet, in particular coming from a faeces collection space, as a result of which they pass through the exhaust air filtering device and are finally filtered through the Cover passage openings are filtered into the room adjoining the reference plane and from there into the surroundings of the separation toilet. If the separating toilet does not have a toilet lid, the room in question can merge directly into the surroundings adjacent to the separating toilet. On the other hand, if the separating toilet has a toilet lid, there can be access to the external environment, for example through a gap between the toilet lid and the seat or, in particular if there is no gap, the toilet lid can optionally be equipped with an exhaust air filtering device according to the first aspect of the invention . Without a toilet lid, a separating toilet can be made comparatively more compact, particularly advantageously with a lower overall height.

An exhaust air filtering device arranged on the cover according to the second aspect of the invention also offers an effective odor barrier between the odor-intensive toilet interior, in particular its feces area, and the external environment of the separation toilet. Depending on the design, it is possible, for example, for only the odor-intensive feces area to be closed using the exhaust air filtering device. Depending on the design, a closed or sealed connection between the urine collection basin and the urine collection container can be advantageous, since no odor can then escape to the outside in this area either.

There is, for example, the possibility that the intermediate wall section through opening is completely or predominantly covered or can be covered by means of the cover, the exhaust air filtering device being attached to a rear side of the cover facing the toilet interior, with the exhaust air filtering device being used to create an air-permeable passage passing through it between the Space that adjoins the plane spanned by the seat and is formed by the toilet interior. It is possible that the front of the cover is exposed in an area bordering the cover passage opening or the cover passage openings, facing the space that adjoins the reference plane spanned by the seat surface, and/or is designed to be connection-free. The cover passage opening or the cover passage openings are or are expediently in fluid communication with the space mentioned, adjacent to the reference plane. Alternatively, there is the possibility that the exhaust air filtering device is attached to the front side of the cover facing away from the toilet interior, with the exhaust air filtering device being used to create an air-permeable passage passing through it between the cover passage opening or the cover passage openings and one per se spanned by the seat surface Reference plane adjacent space is formed.

According to a third aspect, the invention proposes to solve the problem a separation toilet with the features mentioned at the outset, wherein at least one housing side wall passage opening is formed in the housing side wall and the separation toilet has at least one exhaust air filtering device which is in fluidic connection with the at least one housing side wall passage opening stands and which is connected in particular to the housing side wall, wherein in particular a plurality of housing side wall passage openings are formed in the housing side wall and the exhaust air filtering device is in fluid connection with the plurality of housing side wall passage openings. Such a separating toilet also advantageously enables unpleasant-smelling gas formed inside to be completely or partially freed of odors by means of the exhaust air filtering device and then released directly into the environment adjacent to the separating toilet. Such a separating toilet also enables the compensation of pressure fluctuations, in particular the reduction of excess pressure inside the toilet. In a separating toilet according to the second aspect of the invention, a cover, by means of which an intermediate wall section through-opening can be covered, is present in order to avoid an uncontrolled gas escape, particularly during periods in which the separating toilet is not being used. In contrast, in a separating toilet according to the third aspect of the invention, the exhaust air filtering device forms an air-permeable passage through the housing side wall and the cover can be used without an exhaust air filtering device arranged thereon, i.e. H. be designed to be simpler, which in particular also simplifies use and cleaning.

An advantageous possible embodiment is seen in that the exhaust air filtering device is attached to the inside of the housing side wall facing the toilet interior, an air-permeable passage leading through it being formed by means of the exhaust air filtering device between the toilet interior and the housing side wall passage opening or the housing side wall passage openings. It is possible that the outside of the housing side wall is exposed in an area bordering the housing side wall passage opening or the housing side wall passage openings and/or is designed to be connection-free. The housing side wall passage opening or the housing side wall passage openings are or are expediently in fluid connection with an external environment of the separation toilet. Alternatively, there is the possibility that the exhaust air filtering device is mounted on the outside of the housing wall, an air-permeable passage passing through it being formed by means of the exhaust air filtering device between the housing side wall passage opening or the housing side wall passage openings and an external environment of the separation toilet.

According to its fourth aspect, the invention proposes a separating toilet to solve the problem, which has the features mentioned at the outset, the separating toilet having a wall having an intermediate wall section, the intermediate wall section being between the toilet interior and a space which is located in the separating toilet a reference plane spanned by the seat surface connects, extends, wherein at least one intermediate wall section passage opening is formed in the intermediate wall section and wherein the separation toilet has at least one exhaust air filtering device which is in fluid communication with the at least one intermediate wall section passage opening and which is connected to the intermediate wall section, wherein in particular a plurality of intermediate wall section passage openings are formed in the intermediate wall section and the exhaust air filtering device is in fluid communication with the plurality of intermediate wall section passage openings. With regard to possible effects and advantages, reference is made to the previous description, in particular regarding the separation toilet according to the second aspect of the invention.

An advantageous embodiment can consist in that the exhaust air filtering device is attached to the inside of the intermediate wall section facing the toilet interior, with the exhaust air filtering device being used to create an air-permeable passage through it between the space that adjoins the reference plane spanned by the seat and the toilet interior is formed. It is possible that the outside of the intermediate wall section is exposed in an area bordering the intermediate wall section passage opening or the intermediate wall section passage openings, facing the space that adjoins the reference plane spanned by the seat surface, and/or is designed to be connection-free. The intermediate wall section passage opening or the intermediate wall section passage openings are or are expediently in fluid communication with the entire space adjoining the reference plane. Alternatively, there is the same possibility that the exhaust air filtering device is attached to the outside of the intermediate wall section facing away from the toilet interior, with the exhaust air filtering device being used to create an air-permeable passage passing through it between the intermediate wall section passage opening or the intermediate wall section passage openings and the space which is located at one of The reference plane connected to the seat surface is formed.

Regarding separating toilets according to the respective aspects of the invention described, there are numerous other options for advantageous further development:

There is always the possibility that the passage openings belonging to the plurality are arranged in a limited area, in particular evenly distributed. The passage openings can be, for example, a perforation, i.e. passage openings formed by perforation.

It is preferred that the exhaust air filtering device has a filter holder which has air-permeable openings and at least one filter medium held in the filter holder, or that the separation toilet has a plurality of exhaust air filtering devices and a respective exhaust air filtering device each has a filter holder which has air-permeable openings and at least one in the filter holder held filter medium. It is preferred that the exhaust air filtering device for different separating toilets according to the invention has the same modular structure and has the aforementioned components. As will be described, an exhaust air filtering device can additionally have fastening pins for its assembly and can optionally be coupled to or have an air flow generating device, such as an electrically operated fan. There is, for example, the possibility that the filter holder is perforated or perforated on at least one side and is therefore permeable to air. For example, the filter holder can be designed like a basket. It is possible for the filter holder to have a housing which is open to a first side and which has a plate on a second side opposite the first side, through which a plurality of air-permeable through openings extend distributed over the plate.

It is considered expedient that the filter holder has a holder plate on its front, in which at least one air-permeable opening, in particular a plurality of distributed air-permeable openings, is formed, and that, starting from the edges of the holder plate, lateral boundaries extend at an angle which are in particular side walls, extend towards a back of the filter holder, that the filter holder is completely open on its back or has air-permeable openings and that at least one filter medium is held in a filter holder chamber bordered by the holder plate and by the boundaries. If the exhaust air filtering device according to claim 1 is attached to the toilet lid, the filter holder can, for example, face the toilet lid passage opening or the toilet lid passage openings with its back, so that the exhaust air filtering device can be connected to the toilet lid by means of the completely open or apertured rear side of the filter holder -Through opening or the toilet lid through openings is in fluidic connection and is in fluidic connection by means of the air-permeable opening or by means of the air-permeable openings in the holder plate with a space adjoining a reference plane spanned by the seat or with an external environment of the separating toilet. If the exhaust air filtering device according to claim 3 is attached to the cover, the filter holder can, for example, face the cover passage opening or the cover passage openings with its back, so that the exhaust air filtering device can be connected to the cover by means of the completely open or apertured rear side of the filter holder -Through opening or with the cover passage openings is in fluidic connection and is in fluidic connection with the toilet interior by means of the air-permeable opening or by means of the air-permeable openings in the holder plate.

If the exhaust air filtering Device according to claim 7 is attached to the intermediate wall section, the filter holder can, for example, face the intermediate wall section passage opening or the intermediate wall section passage openings with its back, so that the exhaust air filtering device can be connected to the intermediate wall section passage opening by means of the completely open or apertured rear side of the filter holder or is in fluidic connection with the intermediate wall section passage openings and is in fluidic connection with the toilet interior by means of the air-permeable opening or by means of the air-permeable openings in the holder plate. An expedient embodiment is seen in that the filter holder has a number of first assembly through-openings, and in a mounting area for the filter holder on the housing side wall or on the toilet lid or on the cover a number of second assembly through-openings, one of which is positioned in each case a first assembly through-opening is assigned, is designed and that a fastening pin is inserted through a positional pairing of a first mounting through-opening and a second mounting through-opening, it being in particular provided that a respective fastening pin has a through hole oriented transversely to its longitudinal direction on its one longitudinal end section, through which a locking pin is inserted through it, and has a pin head on its other longitudinal end section, which has a comparatively larger cross section compared to the assembly passage opening adjacent to it. The modular filter holder advantageously enables simple, tool-free replacement of the filter medium as soon as it is exhausted. It is understood that the exhaust air filtering device, in particular its filter holder, can alternatively be attached to a mounting area of the separating toilet in a manner other than with fastening pins, for example screwed to the mounting area, pushed into a guide, clipped, glued or the like. It is preferred that the fluidic passage formed by the exhaust air filtering device passes through at least one filter medium accommodated in the exhaust air filtering device. It is considered expedient that the filter medium has a proportion of filter material or consists of filter material and/or that the filter material has absorptive properties, in particular for odorous substances from faeces digestion gas, absorptive properties. It is possible that the filter medium is an activated carbon-based filter medium, in particular activated carbon fleece, activated carbon granules or a multi-layer air filter. It is preferred that the filter material contains a proportion of activated carbon or consists of activated carbon. It is considered expedient that the filter material is arranged in at least one filter layer along a filter plane. It is possible that the filter layer extends adjacent to the, in particular entire, area of the holder plate in which the at least one air-permeable opening of the holder plate is formed or in which all air-permeable openings of the holder plate are formed, in particular in the form of a continuous filter layer . The filter layer can extend over the cross section of the at least one air-permeable opening in the holder plate or over the cross sections of all air-permeable openings in the holder plate. If the exhaust air filtering device is arranged on the toilet lid, there is the possibility that the filter layer is adjacent to an, in particular entire, area of the toilet lid in which the at least one toilet lid passage opening is formed or all toilet lid passage openings are formed, in particular in the form of a continuous filter layer. The filter layer can extend over the cross section of the at least one toilet lid passage opening or over the cross sections of all toilet lid passage openings. The filter layer can be arranged between the mentioned area of the toilet lid and the holder plate. If the exhaust air filtering device is arranged on the cover, there is the possibility that the filter layer is adjacent to an, in particular entire, area of the cover in which the at least one cover passage opening is formed or all cover passage openings are formed, in particular in the form of a continuous filter layer. The filter layer can extend over the cross section of the at least one cover passage opening or over the cross sections of all cover passage openings. The filter layer can be arranged between said area of the cover and the holder plate. If the exhaust air filtering device is arranged on the housing side wall, there is the possibility that the filter layer is adjacent to an, in particular entire, area of the housing side wall in which the at least one housing side wall passage opening is formed or all housing side wall passage openings are formed, in particular in the form of a continuous filter layer. The filter layer can extend over the cross section of the at least one housing side wall passage opening or over the cross sections of all housing side wall passage openings. The filter layer can be arranged between the mentioned area of the housing side wall and the holder plate. If the exhaust air filtering device is arranged on the intermediate wall section, there is a possibility that the filter layer adjacent to an, in particular entire, area of the intermediate wall section, in which the at least one intermediate wall section passage opening is formed or all intermediate wall section passage openings are formed, in particular in the form of a continuous filter layer. The filter layer can extend over the cross section of the at least one intermediate wall section passage opening or over the cross sections of all intermediate wall section passage openings. The filter layer can be arranged between said area of the intermediate wall section and the holder plate.

On the one hand, there is the possibility that the exhaust air filtering device is not combined with an electrically operable air flow generating device. In this respect, one can also speak of a passive exhaust air filtering device. Also depending on the respective design of a separation toilet according to the invention, a significant amount of air or gas can be filtered as it flows through the exhaust air filtering device by means of such a comparatively simple structure and independent of electrical voltage and therefore advantageous exhaust air filtering device. It is possible, for example, for the filter plane to be oriented parallel to a reference plane spanned by the seat of the toilet or at an angle of inclination of a maximum of 45 degrees. Such an orientation proves to be advantageous, particularly with regard to an exhaust air filtering device that is not combined with an electrically operable air flow generating device, since the filter material then forms a comparatively large passage area for gases that rise upwards due to their lower density compared to clean air .

Furthermore, there is the possibility that an air flow generating device is arranged adjacent to the, in particular adjacent to the exhaust air filtering device, wherein the air flow generating device has air flow generating means, such as in particular a propeller or a fan impeller, as well as a motor coupled thereto for the rotary drive and in particular a housing. The housing can be attached to the filter holder and/or to its mounting area located on the toilet housing, or on the toilet lid, or on the cover, or on the intermediate wall section. This allows the filtered gas flow to be increased or increased. It is preferred that the motor is an electric motor, with either the separating toilet having an energy supply device, such as a battery or an accumulator, to which the electric motor is connected, or the electric motor being connected to a voltage source that does not belong to the separating toilet can be connected. If, for example, according to the first aspect of the invention, the exhaust air filtering device is attached to the toilet lid, unfiltered gas can escape from the separating toilet into the environment, for example through an air gap existing between the toilet lid and the seat or the toilet housing. If the exhaust air filtering device is coupled or equipped with an air flow generating device, the filtered air flow can be increased, which can also counteract the leakage described. In addition, an air flow generating device enables the filter position in the separating toilet to be selected more variably, since a constant negative pressure can be generated. An air flow generating device (e.g. a fan) also offers advantages in separating toilets in which the exhaust air filtering device forms an air-permeable passage through the side wall of the housing. In this context, an air flow generating device can prevent the escape of odors, especially while using the separating toilet with the lid open for this purpose. Finally, an air flow generating device in separating toilets according to each of the aspects of the invention can also offer advantages if the toilet housing is not designed to be gas or airtight; Even with such separation toilets, filtering can be supported by an electric fan by generating negative pressure. Depending on the requirements, an air flow generating device can be combined with an exhaust air filtering device mounted on a toilet lid, on a cover, on a housing side wall or on an intermediate wall section. Even if an air flow generating device is arranged adjacent to, in particular adjacent to, the exhaust air filtering device, depending on the design of the separating toilet, in particular depending on the location of the exhaust air filtering device, there is the possibility that the filter plane is parallel or parallel to a reference plane spanned by the seat of the separating toilet is oriented at a maximum inclination angle of 45 degrees.

It is considered expedient that the air flow generating device is suitable for generating an air flow that is directed from the separation toilet into an external environment of the separation toilet.

It is possible that the housing side wall passage opening or the housing side wall passage openings, with which or with which the exhaust air filtering device is in fluid or air-permeable connection, are formed in a section of the housing side wall which adjoins the toilet interior and which, if in the Toilet interior a faeces collection container is accommodated, which is adjacent to the faeces collection container. It is possible that in a use position of the partition toilet in which its seat is directed upwards and in which the toilet lid is closed, the toilet lid passage opening or the toilet lid passage openings extend or extend in the highest area of the toilet lid. It is considered expedient that in a preferred position of use of the separation toilet, in which its seat faces upwards, the exhaust air filtering device is arranged higher than an upper edge of the faeces collection container, in particular above the faeces collection container. In particular for the use of an exhaust air filtering device without an air flow generating device, it is preferred that the exhaust air filtering device is higher than an upper edge of the faeces container in relation to a position of use of the separation toilet in which the seat faces upwards, in particular above (i.e. overlapping in a vertical projection to) that Faeces container is arranged. In this respect, for example, the already described possibility of mounting the exhaust air filtering device on a toilet lid or on the cover already described or on the intermediate wall section already described or on the side wall of the housing comes into consideration. As has already been explained, it is advantageous that a large part of the gases in the gas mixture that typically occurs in separation toilets, namely digester gas from the faeces area, is lighter than clean air (or ambient air) and therefore rises into air with a higher density due to its comparatively lower density . This flow behavior, in which unpleasant-smelling gases rise upwards due to their lower density compared to clean air, can be exploited by the invention in particular in that the exhaust air filtering device in or on the separation toilet (based on a state of use in which the seat surface rises points) can be arranged higher than the upper edge of the faeces container. In order to increase the effect, the exhaust air filtering device can be arranged specifically in the flow area of the gases that forms within the separation toilet due to the density differences, so that the gases inevitably flow through the exhaust air filtering device. Alternatively or in combination, heating of gases inside the separating toilet, which is possible due to various causes, can also lead to or contribute to a forced flow through the exhaust air filtering device due to their resulting decreasing density and/or due to a resulting increase in pressure inside the separating toilet. Possible causes of warming in vehicles and mobile cabins can be, for example, solar radiation, a room heater, engine heat or differences in driving and positioning, especially in winter. An exhaust air filtering device that is not coupled to an electrically operable air flow generating device can therefore also filter gases flowing through it, and it is possible that the filtered gases only enter the separation toilet in a state that is completely or predominantly free of unpleasant odors Separate toilet can leave the surrounding area.

It is possible that the housing side wall and the housing base are designed to be gas-tight, in particular that a contact area between the housing side wall and the housing base is sealed or gas-tight, in particular that a contact area between the toilet housing and the separating insert is sealed or gas-tight, in particular in the closed state of the toilet lid, a contact area of the toilet lid is sealed or gas-tight with the toilet housing, in particular that in the closed state of the toilet lid, a contact area of the toilet lid is sealed or gas-tight with the separating insert, and in particular that a connection between the urine collection basin and the urine collection container, by means of which the urine collection container and the urine collection basin is in fluid communication with one another, is sealed or gas-tight. In the above context, gas-tight means that at the pressures that usually occur inside separation toilets, there is a sealing effect for the gas that is usually formed there, preventing the gas from passing through. In the above context, sealed means that at the pressures that usually occur inside separation toilets, there is at least an effect that counteracts the passage of the gas for the gas that is usually formed there.

The cover can, for example, be designed in such a way that, when the seat faces upwards in a position of use of the separation toilet, it can be placed from above into or onto the faeces shaft housing and can be supported on or therein. If necessary, in particular in order to use the separation toilet, such a cover can be lifted off or from the faeces shaft housing and removed.

In an expedient embodiment, it is provided that the cover has an edge along its circumference, which determines a cover cross section of the cover in a reference plane spanned by it, so that the feces shaft housing is cross-sectionally different from a first in a section of the feces shaft housing in a direction leading to the toilet interior Hollow cross section reduced to a second hollow cross section and from there further to a third hollow cross section, with one roof th geometric superposition of the first hollow cross-section and the cover cross-section, the first hollow cross-section protrudes along its cross-sectional edge beyond the cover cross-section, the second hollow cross-section corresponding to the cover cross-section and wherein in an imaginary geometric superimposition of the third hollow cross-section and the cover cross-section, the cover cross-section protrudes along its cross-sectional edge over the third hollow cross-section . This advantageously makes it possible for the cover to be inserted into the faeces shaft housing until it is supported on the inside of the faeces shaft housing and thereby held, with the cover, if necessary, being released from its seat again by a movement in the opposite direction in the feces shaft housing and out of the feces shaft housing can be removed. If the second hollow cross-section corresponds to the cover cross-section, this advantageously makes it possible to insert the cover into the faeces shaft housing along its outer edge in a completely gap-free or almost gap-free manner and thus in a completely odor-tight or almost odor-tight manner and yet to hold it releasably in the feces shaft housing. It is possible that a handle is arranged on the cover, in particular on a plate-shaped section, which can simplify insertion of the cover into the feces shaft housing and removal therefrom.

The cover can preferably have a flat section. Depending on the design, air-permeable cover passage openings can preferably be formed therein and an exhaust air filtering device can preferably be attached thereto. An edge region can adjoin the flat section along the circumference, which preferably extends in an inclined or curved manner towards the flat section. The cover can, for example, have the shape of a shell which widens towards the edge in the edge region. Particularly in this context, the possibility is also considered that the faeces shaft housing can taper downwards. In particular, an inclination or curvature of the edge region of the cover can be geometrically adapted to a taper of the feces shaft housing so that in a sitting position of the cover, in which it is supported on the inside of the feces shaft housing, there is flat (i.e. not just linear) contact along the circumference between the cover and the faeces shaft housing. With an appropriate design, the cover can in principle clamp in the faeces housing shaft like a conical glass closure (“glass stopper”) in a conical bottle neck. To easily remove the cover from the feces shaft, a handle, such as a loop or a handle, can be attached to the cover. Alternatively or in combination, an escape of odors from the toilet interior into the surroundings of the separating toilet can also be counteracted by sealing a fluidic connection between the urine collection basin and the urine collection container, in particular with respect to the toilet interior.

There are also alternative design options regarding the cover. There is thus the possibility that the separating toilet comprises a cover device which has a cover, the cover being movable back and forth between an open position and a covering position, whereby when the faeces collection container is located in a receiving area assigned to it in the toilet housing and the cover is in its open position, an opening of the faeces shaft housing, which faces an opening of the faeces collection container, is completely or predominantly exposed, the cover, when it is in its covering position, completely or partially covering said opening of the faeces shaft housing, the The intermediate wall section in particular forms the feces shaft housing and the opening of the feces shaft housing is in particular the intermediate wall section through-opening. In order to achieve a space-saving structure, it is preferred that an edge region of the cover facing the drain nozzle is positioned at least in the open position of the cover and in particular in the covering position of the cover between an edge region of the faeces shaft housing facing the drain nozzle and an outer side of the drain nozzle. This embodiment variant is also suitable for either sealing the faeces area or covering it in an odor-reducing or odor-tight manner using an exhaust air filtering device. Unlike the embodiment described above, in which the cover, comparable to a lid, can be put on and taken off, this can be omitted if the cover can be moved back and forth between an open position and a covering position. The operation and especially the opening of the feces area can be made more comfortable. Another advantage is that no “lid” has to be put aside. It is preferred that the cover device has a slide and a slide guide, the slide having the cover and an actuating element connected to the cover, that first guide means are attached or designed on the slide, in particular on the cover, so that the slide Guide has second guide means, which are attached or formed on the toilet housing and / or on the separating insert, and that the first guide means and the second guide means have a positive fit cooperate to guide the cover along a predetermined guide path of the cover between its open position and its covering position. It is considered expedient that the cover can be displaced between its open position and its covering position by means of the first guide means and the second guide means along the, in particular rectilinear, guide path. The actuation of the slide may be by means of a rod which may be pulled outward or pushed inward through a seal in the toilet body to slide the cover back and forth between the open and covered positions. Using this design, the opening in the outer skin of the separation toilet and thus the area to be sealed can be minimized. The slider can run on two sliding guides that are mounted on vertical housing struts, which in turn can be fixed to the housing side wall. It is preferred (as in the embodiment with the “lid-like” cover) that the exhaust air filtering device is positioned in the covering position above the feces container and can therefore be optimally and directly flowed through by the gases.

Regarding the toilet lid passage openings, the cover passage openings, the side wall passage openings, the intermediate wall section passage openings and also regarding the openings in the holder plate of the exhaust air filtering device, there is, for example, the possibility that these are designed as perforations or in another way.

The present invention also relates to a use of a separating toilet, the separating toilet being a separating toilet according to the invention, in particular a separating toilet according to one of claims 1 to 30, and wherein gaseous fluid from the toilet interior, which fluid in the toilet interior in particular by means of faeces has formed odor, is filtered by means of the exhaust air filtering device and is released in the filtered state from the separation toilet into an environment adjacent to the outside of the separation toilet. The present invention also relates to a method for operating a separating toilet, the separating toilet being a separating toilet according to the invention, in particular a separating toilet according to one of claims 1 to 30, and wherein gaseous fluid from the toilet interior, which fluid in the toilet interior in particular has an odor formed by feces, is filtered by means of the exhaust air filtering device and is released in the filtered state from the separation toilet into an environment externally adjacent to the separation toilet. Regarding the use and the method, reference is also made to the remaining disclosure relating to the invention for effects, advantages and possible further developments.

Description of the embodiments

With reference to the 1 to 4 A first exemplary embodiment of a separation toilet 100 according to a first aspect of the invention is presented. This includes a toilet housing 101 and a separating insert 102, which together border a toilet interior 103, a urine collection container 104 and a faeces collection container 105, which in the figures are both accommodated in the toilet interior 103 and can be removed from it for emptying, and a toilet lid 106. In the example The toilet housing 101 has an outer housing side wall 107, a housing base 108 and a plurality of housing supports 109, which are connected to the housing side wall 107 and the housing base 108 in the toilet interior 103 bordered by the housing side wall 107. The housing side wall 107 extends continuously along the top view of 2a , 2 B visible circumference of the separating toilet 100. In a position of use of the separating toilet 100, in which the housing base 108 is placed on a surface (see also 3a , 3b) , the housing side wall 107 forms an upper edge, to which reinforcing elements are attached in the example. Through the upper housing opening 110 of the toilet housing 101 formed in this way, as shown in the figures, the separating insert 102 can be practically completely inserted into the toilet housing 101, whereby it borders the toilet interior 103 at its upper region. In order to be able to remove the urine collection container 104 and the faeces collection container 105 from the toilet interior 103 for emptying and cleaning, the separating insert 102 can first be lifted off the upper edge of the toilet housing 101 and removed from the toilet housing. The separation toilet 100 has a urine receiving basin 111, which borders a urine receiving space 112 and on which a drain connection 113 is arranged, and a faeces shaft housing 114, which borders a faeces shaft space 115. The urine collection container 104 borders a urine collection space 116, and the feces collection container 105 borders a faeces collection space 117. Like in particular 3a , 3b show, when the separation toilet 100 is in a usable state, the urine receiving space 112 and the urine collecting space 116 are fluidly connected to one another by means of the drain connection 113, so that urine can flow from the urine receiving basin 111 into the urine receiving space 112. In the exemplary embodiment, an opening 120 forms the faeces shaft housing 114, which is the faeces collection container 105 when it is in it assigned receiving area of the toilet interior 103, faces a passage through which feces can pass from the feces shaft space 115 into the feces collection space 117. In the exemplary embodiment, the receiving areas of the toilet interior 103 intended for receiving the urine collection container 104 and the faeces collection container 105 are determined by means of recesses 118, 119 in the housing base 108. By way of example, it is provided that the urine collection basin 111 and the faeces shaft housing 114 are formed in one piece by means of the separating insert 102 and are laterally spaced apart from one another by means of a dam 121, also formed on the separating insert 102. In the position of use of the separating toilet 100 shown in the figures, in which its housing base 108 stands on a surface, a seat 122 of the separating toilet 100, which is formed by the separating insert 102, points upwards. In the example, the toilet lid 106 is designed without a hinge and, as required, can either be placed loosely on the separating insert 102, as shown in the figures, or removed to use the separating toilet 100 or, for example, to remove the separating insert 102. It goes without saying that alternative configurations are also possible, in which the toilet lid can be attached, for example, by means of a hinge, either to the toilet housing 101 or, for example, to the separating insert 102.

With the one in the 1 to 4 In the exemplary embodiment shown, a plurality of distributed toilet lid passage openings 123 are formed in a central area 130 of the toilet lid 106, each of which is permeable to air. The separation toilet 100 has an exhaust air filtering device 124. This includes a filter holder 125, which has a holder plate 126 on its front with a plurality of air-permeable openings 127 distributed therein. In the example, the holder plate 126 has a square edge contour. Starting from the four edges, each angled at right angles to the holder plate 126, a lateral boundary in the form of a respective side wall 128 extends towards a rear side of the filter holder 125, which is attached to the area 130 of the toilet lid 106 designed with the toilet lid passage openings 123 adjacent. In the example, the filter holder 125 is open at its back. A filter medium 131, which is permeable to air and has odor-absorbing properties, is held in a filter holder chamber 129 bordered by the holder plate 126 and the side boundaries. Like in particular 4 clarified, the filter holder 125 faces the toilet lid passage openings 123 with its open back. The exhaust air filtering device 124 is therefore in air-permeable (thus fluidic) connection with the air-permeable toilet lid passage openings 123. 3b , in which the toilet lid 106 is removed, shows schematically that the seat 122 geometrically spans a reference plane E. The reference plane E is bordered by a space 132 bordered by the separating insert 102, areas of which form the urine receiving space 112 and the feces shaft space 115. By means of the air-permeable openings 127 extending through the holder plate 126, the exhaust air filtering device 124 is also in an air-permeable, and therefore fluid-permeable, connection with the space adjacent to the reference plane E.

In the example, the exhaust air filtering device 124 is attached to the inside of the toilet lid 106. In the 1 to 4 the attachment of the drain filtering device 124 to the toilet lid 106 is realized, for example, by means of four fastening pins 133. A respective fastening pin 133 is inserted through a mounting passage opening 147 in the toilet lid 106 and through a mounting passage opening 136 in the holder plate 126. A respective fastening pin 133 is secured against unintentional loosening at one longitudinal end by means of a pin head 134 with an enlarged cross section and in the area of its other longitudinal end by a locking pin 135, which is inserted through a through hole running transversely to the longitudinal direction of the fastening pin 133. In this way, the exhaust air filtering device 124 is attached to the inside of the toilet lid 106. It is understood that this type of attachment is only described as an example, and that alternatively there are various other options for attaching the exhaust air filtering device 124, such as a clamp connection, a clip connection, a screw connection, an adhesive connection or the like.

From the 1 to 4 and from the description it is clear that by means of the exhaust air filtering device 124 an air-permeable, odor-absorbing passage is formed between the space 132 in the separating insert 102 and the toilet passage openings 123. In the example, ie not necessary, there is a further space 138 between the space 132 and the toilet lid 106. In the example, the air-permeable passage between the space 132 and the toilet lid passage openings 123 is also formed by means of this further space 138. Like this in particular 1 and 2 show, the outside of the toilet lid 106 is exposed in the area 137 bordering the toilet lid passage openings 123. Through the toilet lid passage openings 123 present in the area 137, an unpleasant smelling gas that has arisen in the toilet interior 103 can be released after the due to its lower density compared to air, it has risen through the faeces shaft space 115 in the separating insert 102 and through the space 138 bordered by the toilet lid 106 to the uppermost area within the separating toilet 100, through the exhaust air filtering device 124 and the toilet lid passage openings 123 exit directly into the environment 139 adjacent to the separation toilet 100. In the area 137 surrounding the toilet lid passage openings 123, no connections are provided on the outside of the toilet lid 106 for a pipe, a hose or the like for discharging the gas, that is, the outside of the toilet lid 106 is designed to be connection-free. In order to achieve as complete an escape as possible of unpleasant-smelling gas, which to a large extent has a lower density than air and therefore rises upwards within the separation toilet, after it has been filtered by means of the exhaust air filtering device 124, the toilet lid passage openings 123 are located above the top one Area of the room 138 bordered by the toilet lid 106.

With reference to the 5 to 15 A separation toilet 200 according to a first exemplary embodiment will be described below with regard to a second aspect of the present invention. For an overview, details are consistent with those from the 1 to 4 match or are comparable, are designated with reference numbers, the last two digits of the number with corresponding reference numbers from the 1 to 4 to match. In this respect, reference is also made to the previous description in order to avoid repetition. In the case of the separating toilet 200, too, a toilet interior 203 is laterally bordered by an outer housing wall 207. Like for example 7 shows, the toilet interior 203 contains an area for accommodating a feces collection container 205 and an adjacent area for accommodating a urine collection container 204. A seat 222 of the separating toilet 200 geometrically spans a reference plane E, to which the separating toilet 200 is located on the underside in the position of use shown in the figures a room 232 adjoins. The separating toilet 200 includes a wall 240, which in the exemplary embodiment is the wall of a separating insert 202 of the separating toilet 200. The wall 240 has an intermediate wall section 241 which extends between the toilet interior 203 and the room 232. In the intermediate wall section 241, an intermediate wall section through opening 242 is formed. In the exemplary embodiment, this is an opening 220 of a feces shaft housing 214, which lies at the lower end of the feces shaft housing 214 in the shown position of use of the separation toilet 200, see also 10 . The separation toilet 200 includes a cover 243, by means of which the intermediate wall section through opening 242 can be covered. For this purpose, the cover 243, such as 7 shows how far into the faeces shaft housing 214, which tapers towards the opening 220, until support in the faeces shaft housing 214 results due to the cross-sectional dimensions of the cover 243. A plurality of air-permeable cover passage openings 244 are formed in the cover 243. The separation toilet 200 has an exhaust air filtering device 224, which, for example 10 can be seen, is in air-permeable connection with the plurality of cover passage openings 244 and which is connected to the cover 243. 7 shows that the exhaust air filtering device 224 is attached to a back of the cover 243 facing the toilet interior 203. A filter holder chamber 229 of the exhaust air filtering device 224, in which an air-permeable, odor-absorbing filter medium 231 is held, borders directly on a wall region of the cover 243, in which the cover passage openings 244 are formed, and is therefore in air-permeable connection with the cover passage openings 244. On the opposite side of the exhaust air filtering device 224, numerous air-permeable openings 227 are formed in the holder plate 226 of the filter holder 225, by means of which the filter holder chamber 229 is in air-permeable connection with the toilet interior 203. Thus, by means of the exhaust air filtering device 224, an air-permeable, odor-absorbing passage is formed between a space 232, which adjoins a reference plane E defined by the seat surface 222 from below, and the toilet interior 203. The front side 245 of the cover 243 is designed to be exposed in the area bordering the cover passage openings 244 and facing the space 232 and without a connection, that is to say without a connection for a hose or a pipe for discharging gases. If, as in 7 is shown, the cover 243 with the exhaust air filtering device 224 attached thereto for covering the opening 220 is inserted into the faeces shaft housing 214, unpleasant smelling gas, which emanates from faeces (not shown) contained in the faeces collection container 205 and is lighter than air, can be removed rise at the top, whereby it is filtered and freed from odors as it flows through the exhaust air filtering device 224 before it can reach the room 232 and from there into the external environment 239 of the separation toilet 200. In the example, the separating toilet 200 is designed without a separating toilet lid. However, it goes without saying that a toilet lid or a commercially available toilet Seating set could be added. For a state of use of the separation toilet 200, in which feces is to be introduced into the feces collection space 217 through the feces shaft space 215, the cover 243, such as in the 9 and 10 shown, can be removed from the faeces shaft housing 214. In order to simplify handling, it is possible for a handle, such as a handle or the like, to be attached to the cover 243, which is not shown in the figures.

In the 11 to 15 In the example, the type of fastening of the exhaust air filtering device 224 which is chosen as an example, ie not necessarily carried out in this way, is shown in more detail. A filter holder 225 of the exhaust air filtering device 224 has a mounting passage opening 236 at each of the four corners of its holder plate 226. On the opposite section of the cover 243, a further assembly through opening 247 is formed at respective assigned positions. Coming from the direction of the cover 243, a fastening pin 233 is inserted through a pair of two mounting through openings 236, 247, so that its cross-sectionally enlarged pin head 234 is supported on the cover 243 and a longitudinal end section 248 of the fastening pin lying at the opposite longitudinal end 233 emerges from the filter holder 225 through its holder plate 226 to the outside. In the longitudinal end section 248, a through hole 249 extends transversely to the longitudinal direction of the fastening pin 233, through which a locking pin 235 for fixing the exhaust air filtering device 224 on the cover 243 can be inserted. Like for example 7 shows, in this exemplary embodiment, in a use position of the separation toilet 200 in which its seat 222 points upwards, the exhaust air filtering device 224 is arranged higher than an upper edge of the faeces collection container 205. Specifically, in this example, the exhaust air filtering device 224 is arranged above the faeces collection container 205, i.e. overlapping with the faeces collection container 205 in a vertical projection view.

The cover 243 has an edge 246 along its circumference, which determines a cover cross section Q _A of the cover 243 in a reference plane spanned by it. The faeces shaft housing 214 reduces in cross-section in its lower section from a first hollow cross-section Q ₁ in the direction of the toilet interior 203, first to a second hollow cross-section Q ₂ and from there further to a third hollow cross-section Q ₃ . In the example, the reduction occurs as a continuous taper due to a slight inclination of the side wall, which is represented by the angle α. The hollow cross-section Q ₂ corresponds to the cover cross-section Q _A , while the first hollow cross-section Q ₁ is comparatively larger and the third hollow cross-section Q ₃ is comparatively smaller. As a result, when the cover 243 is lowered into the faeces shaft housing 214, it is supported therein at the level at which the cover cross section Q _A reaches the hollow cross section Q ₂ .

With reference to the 16 to 21a A second embodiment of a separation toilet 200 according to the second aspect of the present invention will be described. For features and details similar to those in the 5 to 15 correspond to the first exemplary embodiment of the second aspect shown, the same reference numerals have been chosen for clarity, and to avoid repetition, reference is made to the previous description. The ones in the 16 to 21a Separating toilet 200 shown differs from the one in the 5 to 15 Separating toilet 200 shown in the design of the cover 243. In the second exemplary embodiment ( 16 to 21a) the cover 243 is part of a covering device 250. This includes a slide 251 and a slide guide 252, the slide 251 having the cover 243 and an actuating element 253 connected to the cover 243. In the exemplary embodiment shown, the latter is formed from a rod and a holding knob arranged at its free longitudinal end. A comparison of the 18a and 18b shows that the cover 243 is between a covering position ( 18a) and an open position ( 18b) can be moved back and forth.
