Sanitary toilet, in particular for vehicles. State of the art and general .

The invention relates to a sanitary toilet and pipe system (also a locking system) which is particularly suitable for use in ships, caravans, other vehicles or portable or movable units. The toilet according to the invention is of the type which has a waste storage space (compartment) which is emptied, for example, periodically (at time intervals) such as, for example, λ at the end of a trip. With the increasing importance of avoiding the pollution of rivers and lakes, in some areas it becomes urgent and even a compulsion to provide a toilet for use in ships, camping caravans and the like any and especially human waste material (e.g. faeces) from such vehicles is prevented.

Although flush closet-type vehicle toilets have been developed and are in use, and although some of these types provide for the storage of waste material which is (again) can be removed, such prior art toilets have numerous disadvantages For example, in those lavatories that are commonly used in vehicles, there is no means for that Separation of the waste material (feces) provided from the flushing liquid, with the result that the Detergent is soiled after using the toilet once. Even though such toilets are common have some means for filtering the rinse water, the filter will nevertheless be at least partially clogged, and the rinse water is very quickly contaminated, with the result that very unsanitary (unhealthy) and odorous conditions arise.

The increasingly tough anti-pollution measures and regulations (against air pollution and the like) that are now in the jurisprudence most countries prohibit the (inter alia: arbitrary) unloading not only from sanitary Toilets, but also from sinks, wash-toilets, Showers, etc., with which many vacation and recreational vehicles and the like. Equipped nowadays are originating waste, therefore it is necessary on or the waste water in the vehicle, which of such

Fixtures going off, as well as storing the sanitary debris collected from the toilets.

U.S. Patent 3,418,664, issued on December 31, 1968 (Owners: Thomas Charmichael and Durrell U. Howard) is an improved water closet discloses which overcomes most of the problems associated with the common type of toilet. Short described comprises the water closet according to said patent a flushing liquid storage container which Rinses bowl after each use. A lock at the bottom or in the bowl blocks the connection between the bowl and waste storage bin during the rinse cycle, but it allows the Flushing liquid to return to the reservoir; as a result, the washing or rinsing liquid can become does not mix with the contents of the waste container and remains essentially even after several flushes unpolluted.

The sanitary toilet according to the aforementioned patent has proven itself on the market and functional proven to be most beneficial. But it still has one with other well-known vehicle water closets Disadvantage in common, and this is that especially when using the toilet with an open bottom lock Littering of waste material into the waste bin is possible, being very easily unhealthy and disgusting Odors emanate from the waste container and into the

109850/1007 " ^{sheet 4} "

Intrusion around the toilet, to the greatest discomfort of the user. As you will see the improved system according to the invention eliminates this problem, while still taking advantage of the device remains, which is described in the aforementioned US Pat. No. 3,418,664.

Outline of the invention :

In the preferred embodiment of the invention a toilet is provided with a first bowl-shaped or bowl-shaped part and a second part, wherein the bowl-shaped part is arranged above the second part, and wherein a first closing means (-link) is mounted in between to selectively move solid and liquid waste from the first part to the to let the second part go through when the closure member is in its open position. A second Closing means selectively blocks the connection between the second part and a line which is closed leads to the waste storage container. A storage container for a rinsing liquid is provided, which for this purpose is used to flush the bowl when the first locking means (member) is closed so that the Rinsing liquid returns to the reservoir, bypassing (by-passing) the waste storage container. A second detergent is provided to draw off waste water, which is in a separate Waste storage container is or has been collected,

- sheet 5 -

109850/1007

-5- March 8, 1971

and the collected waste water is used as flushing liquid for the second and lower part of the toilet used · The last-mentioned rinsing process (step) can take place together (simultaneously) with the first rinsing process at a time during which the first closure means closed and the second closure means open · the waste material and the rinsing liquid go through an opening in the lower portion of the second part of the (entire) toilet bowl, and go through this Area to a separate waste storage bin.

The sinks, wash toilets, showers and the like in the vehicle are connected to the waste storage container by a common waste line II, and means are provided in said container for separating the sanitary residues from the waste water. The waste water is then used as a source for the (each) takes place after use of the toilet flushing i of the second or lower part of the toilet.

The collected sanitary waste and that separately Collected waste water can also be sucked or discharged from the vehicle to the outside through a single outlet. So: Any waste generated or created inside the vehicle is sanitary waste and the waste (waste) water coming from the shower or the wash toilet or the like, and the

109850/1007

March 8, 1971

Waste dirt (e.g. residues) and the water that was Handling and preparing food accumulate can be removed from a single collection point, even if the different pipeline parts etc. are scattered over the whole vehicle, e.g. also the pipe connections, drains and the like.

The first and the second locking means are each associated with actuating means which the control both locking means in such a way that at any time only one such locking means can be open. It follows that at no time is there a direct connection from the waste storage container to the first part, i.e. to the bowl area; a further result is that an exit or The passage of disgusting (unpleasant) smells into the rooms around the toilet is eliminated.

It is therefore an object of the invention to provide a sanitary toilet for use in vehicles or the like (e.g. also aircraft), which is particularly suitable for use (installation) in ships, Caravans, yachts or other moving vehicles or bodies. The toilet according to the invention provides a separate garbage storage space (or partitioned space) which periodically, such as for example, at the end of a journey, is emptied, and the (unintentional) unloading or escape of

any waste material and in particular human waste (feces) out of the vehicle is absolutely prevented. This waste storage space is provided with means for separating that waste water provided, which is collected (accrues) from the various pipes (drains) that are everywhere in the Vehicle are arranged, of that sanitary waste that is collected (accrues) from the sanitary toilets becomes «(separation of solid waste and sewage) ·"

Another object of the invention is to provide a flush type vehicle sanitary toilet, which contains a relatively small amount of treated (e.g. treated) rinsing water (rinsing liquid) recycled (recirculates again and again), namely this rinsing liquid is recycled for many rinses, without the liquid being significantly contaminated. The amount (bulk) of the waste material is removed by a second flushing operation. '' guided or derived which waste water (sewage) used, which had been collected separately in the separate waste storage room (compartment).

Detailed description of the preferred embodiment

Figure 1 shows the toilet _e "and the piping system of the preferred embodiment. The toilet is contained in a box 10 and encloses a first or bowl portion 11 and a second and lower portion 12 for temporary storage. These two parts 11,12 are separated by the shutter 13 which is operable between open and closed positions, and this allows solid waste and liquid waste to pass through (fall) from the upper part 11 into the lower part 12 when the shutter 13 is in its open position. The seat member 14 (toilet seat) is mounted above the box 10, coaxially in alignment with the upper toilet part 11, and the lid 15 is pivotably mounted above the seat 14 on the rear edge of the box 10. The rotation (pivoting) of the lid 15 can be coupled directly to the shutter actuating mechanism 16 by means of a shaft 17 or other suitable actuating means or mechanisms. The details of this mechanism are not essential to the present invention, but they can, for example, be a 109850/1007 - ⁵ ^ U 9 -

Form as shown in U.S. Patent Application 848,221 dated August 7, 1969, or it may take the form as in the aforementioned U.S. patent 3,418,664 is indicated. The lid 15 can be attached to the Shutter actuation mechanism 16, for example, by an electrical clutch or by an electromechanical Device or the like. Be connected.

When the cover 15 is raised into its upper position, the closure member 13 is in its open position pulled (withdrawn) so that there is direct (spatial) connection between the bowl 11 and the lower Parts 12 allowed. When the upper shutter 13 is open, the lower shutter 18 is closed; correspondingly, the lower shutter 18 is open when the upper shutter 13 is closed »this one The second closure 18 is arranged below the one in the lower region of the second and lower part 12 Waste outlet arranged. The shutter 18 is also operated by the shutter operating mechanism controlled by means of the shaft 19 which extends through the shaft housing 20 and is anchored to the closure 21.

Waste water 37 is collected from various pipes or drains, which through the Vehicle are arranged therethrough; such drains are a shower 38, a wash toilet 39, a Sink 40 · The waste water from the drains

or connections or the like. Solid and liquid waste goes from the sanitary toilet 11 through the line 33 'zd the waste storage space (compartment) 34. The entire waste storage container 29 is provided with means 35 (e.g. a wall) which are used to separate the sanitary Waste 36 from water waste (sewage) 37 serve. A pump 28 is arranged locally within a filter element 45, for separating the waste (waste) water collected in space (compartment) 44 from any solid or nearly solid waste that may have been collected in 44, e.g. from the food preparation Place of incoming waste (leftovers), this place being provided with the sink 40, or, for example, small bars of soap and human hair that come from the shower 38 or the wash toilet 39, for example. The container 29 can be emptied with the aid of a drain 46 which leads to the outside of the vehicle. This drain (drainage line) 46 is connected to the waste storage space or compartment 34 of the container 29 with the aid of a line (branch) 47 and with the water storage space (compartment) 44 fe £ 4 with the aid of a line (branch) 48 . Each of these lines 47, 48 is correspondingly connected to its own shut-off valve 49 and (Äbscblußschieber or the like.) So that any contamination of the water storage space 44 by sanitary waste from space 34 is prevented

109850/1007

- sheet 11 -

-11- March 8, 1971

Normally, the valves 49 and 50 are closed all the time the vehicle is in use. If the water storage space 44 is filled ₉ before the sanitary compartment (-Room) 34 is filled or * is, the excess waste water can be drained off ₉ namely by opening the drainage (overflow) 51t which normally with the help of a locking valve (locking slide) 52 is closed. It should be emphasized that under normal circumstances it would be desirable to have a small portion of the waste to leave water 37 left over, so leave 44% u in the water storage space, for use in the second phase of the rinsing cycle, as described below.

under such conditions where unloading (Discharge) of any waste material, whatever it may be, is prevented if that Compartment or space 44 (itself) in front of space 34 fills, the one-way valve 53 (check valve) will allow, that the excess waste water in space 44 in the |

Sanitary room 34 flows without this being allowed any sanitary waste (feces or the like) overflows or flows back into the seam 44.

Function ;

During the use of the toilet, the lid 15 is in its opened position, so that Waste material pass directly through the bowl 11 and the now open closure 13 into the lower part 12 (fall) can. The second, lower closing organ is now closed.

109850/1007 -sheet 12 -

-12- 6th March 1971

After the toilet has been used, ^ as a result of the folding down of the lid 15, the first closure 13 is closed and the lower closure 18 is opened. The flush circuit is then energized and this can be achieved by actuating the push button 30 or the like mounted on the top of the box 10. Appropriate interlocks may be provided be, as they are published, for example, in the already mentioned US Pat. No. 3,418,664, in order to protect the circuit (circuit) and the pump drive against current energy supply when the shutter 13 is open When the circuit is energized, The pump 22 draws the rinse water 23 from the lower part of the box 10 and pumps it up through the conduit 24 to the discharge opening (rinsing nozzle) 25 located in the upper periphery of the upper part 11 the opening (nozzle) 25 can be arranged tangentially in order to force the (rinsing) water to swirl around the circumference of the interior of the bowl 11 during the rinsing process.

An open ring 26 is arranged between the first and second parts of the (entire) toilet bowl directly above the closure 13, and it has a plurality of openings 27 for deflecting or draining the flushing liquid back into the flushing liquid reservoir in the lower part of the box 10 when the shutter 13 is closed. So you can see

-Sheet 13 -109850/1007

-13- March 3, 1971

that the greater part of the waste collected (accrued) during use is in the lower part Is deposited, and that the rinsing liquid solution or the like. Which cleans the bowl 11, not with comes into contact with any substantial amount of solid or liquid waste. Simultaneously with the The first flushing process, the pump 28 housed in the container 29 is set in motion, and this pump forces the clarified (strained) and filtered waste water from the plumbing system to the top | from the line 31 to the outlet 32, which is arranged in the upper part of the lower bowl 12, to flow. The water enters this bowl tangentially to tangentially around the circumference of the inner surface the bowl 12 to swirl or swirl. This second rinse action can result in a larger amount of liquid than the first rinse which is effected by the pump 22. The waste water is then used to remove the solid, to transport substances down through the outlet, the one in the lower part of the lower toilet bowl is attached, and further through the waste line into the sanitary storage space 34 of the container 29.

It is intended and suggested that the first rinse liquid 23 normally includes water which is treated with a germicidal (germicidal) or antiseptic solution or

-Sheet 14 -

2111032 is mixed, and that this water is used to clean the upper part of the toilet and to keep the toilet in a hygienic condition,

Fig. 3 shows another embodiment of the invention, which is particularly suitable for ships or for mobile or mobile homes or houses, such as residential trailers, caravans, etc. This embodiment can be used whenever a source or other supply of fresh water is abundant. The fresh water supply or source is or is connected to the line 60 and goes through the T-piece 61 (fitting) to solenoid valves (solenoid valves) 62 and 63 _f, the function of which will be described later.

Referring to Figure 2, a suitable power source is applied to terminal 80 of the circuit. A backup or a circuit breaker (overcurrent relay) 81 prevents any of the actuating pumps or one of the valves is overloaded, for example as a result of a short circuit or other poor function. ' The current then goes to the timer (timer, timing relay, clock) 82 which determines the duration of the flushing processes. A rinse cycle can be initiated by pressing a weight-sensitive switch (not shown) as previously described, or by means of an external push button, as in Fig. 1 shown to be effected. In any case, by resp. after the start of the rinse cycle interval, as shown in the diagram

- sheet 15 -

109850/1007

-15- March 8, 1971

2111032 shown in Fig. 2, the pump 22 can be activated to perform a rinse of the bowl 11 "when or while the shutter 15 is closed.

For this embodiment of the invention is a Circuit shown in Fig. 2; it has a two-way switch 84 (two-way selector switch), which between a so-called working position ("travel position", with the flushing water circuit pump 28 running) and a fresh water position (fresh water position "for supplying τοη fresh water to the Flush) is operated selectively · Assuming the vehicle is in use, perhaps over Driving on a motorway or the like, such as in the case of a caravan, then the holder 84 is in his upper or "travel-position" set so as to supply (drive) the pump 28 (with electricity) during the by the timer 82 to certain isL intervals to back up. The in, Fig. Pump 28 shown in FIG Circulating flushing water from the water storage space 44 via (through) the line 31 to the lower part 12. So it can be seen that whenever the switch 84 is in its "travel-position", the Function of the embodiment of the invention according to FIG. 3 is exactly the same as the embodiment shown in Fig. 1

When the system is to be used in conditions where fresh water is readily available or

- sheet 16 -

109850/1007

-16- March 8, 1971

is present, the switch 84 is turned to the lower or fresh water position, and it continues here takes the pump 28 out of service and instead operates the conditioning valve 62. That Valve 62 is then turned on during the time interval predetermined by the timer (or timer) 82 brought its open position. In other words, under under these conditions the flushing of the lower part of the sanitary toilet from the line 60 (Fig.3) instead of using water which was or is stored in the water storage space 44. Although this type of operation of the system entails the consumption of larger amounts of water the further result that the waste storage space 34 will then be filled more quickly, it must be said, that under the conditions where fresh water is readily available then it usually becomes possible that Drain 46 (Fig. 1) with a drain, gully or the like. (sewer) so that there is then no need to store rubbish in room 34, and instead of saving you can then the waste directly into such a sewer, drain connection, sewer, gully or the like. let it flow.

Figs. 2 and 3 show another feature which is used in the plumbing toilet according to the invention After this, the fresh water available from the line 60 can be selectively added open valve 63 through line 60 and into or

- sheet 17 -

1 09850/1007

-17- March 8, 1971

flow through the opening 64 in the upper part of the bowl 11. It should be noted that a pressure switch 71 is connected in series with valve 63 as shown in Fig. 2 which applies power to open valve 63 whenever the pressure switch is closed. Such actuation of the valve 63 can, according to the instructions for the user, be carried out whenever the toilet has been used and if it is desired to flush the bowl 11 with a * small amount of fresh water before starting the regular flushing cycle ( pre-rinse). Thus, it must be remembered that, according to the invention, the shutter 13 is closed during the regular wash cycle (main wash). Consequently, no waste that may be left on the inner surface of the bowl 11 can enter the lower part 12 during the regular wash cycle . However, will allow a short-term actuation of the valve before the normal (main) wash cycle (and similar effect) so that such waste material from the bowl 11 in.den lower part 12 is flushed before the shutter 13 is closed, and (before) of the regular (Main.) Rinsing process begins. If desired, the switch 71 can be of the type which keeps the circuit closed only for a predetermined time or a predetermined time interval of a few seconds (short-term relay switch) once it has been actuated once, and it can thereby do the amount of Limit water consumed during this pre-rinse
