Abstract

In a process for using a seat-type toilet, urinal, or similar, foam is produced before excrements are deposited in the bowl. For this purpose a foaming agent is added to the flushing water in order to form a foam mat in such a way that the foaming agent reaches the bowl together with the flushing water and foam is produced simultaneously. The foaming agent is introduced into the flushing water pipe (17) by a flushing valve (10) arranged in the flushing water pipe (17), immediately below the air inlet opening (18) for the flushing valve (10), in particular shortly before the end of the flushing process, i.e. shortly before the pressure flusher (10) returns to its closed position.

Description

Method and arrangement for using a seat toilet,

Urinals or the like

The invention relates to a method and a device for using a seat toilet, urinals or the like, in which foam is generated before the excrement is deposited in the bowl.

DE-C-20 23 133 discloses a method for odorless depositing of excrement in a toilet bowl provided with a water rinse of the usual type, in which, prior to depositing the excrement, a foam-forming preparation in tablet form or in an aerosol can is placed in the toilet bowl a foam pillow is generated, which when you press the water flush together with the excrement is removed. This procedure has never been put into practice. The reason for this is in all likelihood that a foam pillow can be produced using tablets or an aerosol can, which at most serves as an odor barrier for 5 minutes until rinsing and which has to be produced in a relatively complex manner, ie by separate manipulation of the user. In addition, it is not possible to distribute the foam cushion evenly over the entire toilet bowl using tablets or an aerosol can.

From DE-C-1 030 267 a system for preventing the spread of odors when using a toilet is also known. This has at least one nozzle connected to a water pipe and opening into the toilet bowl,

^• A distributor cone is arranged behind the mouth of the water pipe and converts the emerging water into a short-term water film bell that shields the bottom of the bowl

The device according to DE-C-1 043 969 also only deals with the odor removal in a toilet bowl. The situation is similar with the extremely constructionally complex arrangement according to US Pat. No. 4,571,752. There, 1 ccm of chemical (= 288 g per day) is distributed every 5 minutes without later binding to the environment, and the toilet bowl smell also every 5 minutes Blower blown up.

In PCT / EP 87/00178, the inventor, based on the prior art mentioned, proposed a method and an arrangement of the type mentioned at the beginning with which a foam cover is produced in the toilet bowl, which is not only used as a permanent Odor barrier is used, but in particular also has a spray-inhibiting effect and which, at the same time, makes it considerably easier to keep the toilet clean. In addition, there are separate manipulations of the user is no longer required.

The present invention is based on the object of also creating a method and an arrangement of the type mentioned at the outset which are distinguished by the same advantages as the system already proposed, but which also have the advantages of an extremely simple construction and in particular has a considerable reduction in the noise level during the rinsing process.

With regard to the method, this object is achieved by the characterizing measures of claim 1 and, if appropriate, one or more of claims 2 to 10, and in respect of the arrangement by the characterizing features of claim 11 and, if appropriate, one or more of claims 12 ff.

The system according to the invention is characterized, in particular in connection with a pressure washer, by an extremely efficient and simple construction, the ambient air (which is sucked in when the pressure washer is actuated) can be used extremely effectively. Therefore, only an extremely small amount of foaming agent is required for each rinsing process in order to produce a sufficiently high foam carpet in the bowl. The system proposed here is accordingly environmentally friendly. Furthermore, this process is very quiet since the foam formation begins before the rinsing water enters and swirls in the toilet bowl or the like. H. foaming water is introduced into the bowl.

Of particular importance with regard to the arrangement in this context are the measures according to claims 13 to 15, which lead to an effective reduction in the noise level when flushing using a pressure winder. _U na _bh ängig _d Avon would be in conventional cistern Anordnun¬ an effective noise insulation gene also possible by _d a _{ß t} he _S Puel _k asten is filled with foam, in particular _b ei emptying of the cistern and / or recovery DES same with fresh water . _F alls _P rotection is for this measure here likewise sought, in combination with the other measures proposed here, but also independently.

When applying the invention on a Saugklosett is to Ma _SS measures according to claims 6 and referenced 7, wherein said Ma _ß participated in principle also to other type toilets th gel¬.

Furthermore, it should be pointed out at this point that the foaming agent is preferably one at the

Bowl surface or substance attached to the bowl edge is used, which is characterized in that it has a dirt-repellent effect, prevents the accumulation of faeces in the entire foam area of the bowl, supports the washing process in its cleaning effect, shortens the pool cleaning time and saves washing water.

Preferably, a foam carpet floating on the water is produced in the bowl, which is at least about 7 cm high and comprises at least about 4 to 20 bubble layers. Then an optimal one

Spray and odor inhibition can be achieved, as tests with an elongated or sausage-shaped mass with a weight of 45 g, a length of 9 cm and an average diameter of 25 mm have shown, from a height of 30 cm to a foam covered water surface is dropped.

Finally, the claimed measures for dissolving the foam are not of minor importance, these measures preferably also being used to wet toilet paper deposited on the foam carpet, so that it sinks a little on the foam carpet and is also extracted with a suction toilet. In the case of a suction toilet, the foam dissolver or water used therefor is preferably injected into the bowl in such a way that the foam is literally rolled with the result that this is on the

Toilet paper placed under the foam carpet gets under the foam carpet and can therefore be easily removed with the excrement. The foam dissolution is also important for residual foam still present in the drain line. This should be included separately with each rinse - if available

Foam breakers are treated and removed. In order to prevent residual foam from rising into the bowl, the measures according to claim 24 can be advantageous.

Independently, but also in combination with the aforementioned measures, the nozzles directed into the bowl or onto the foam carpet for introducing a foam dissolver or a water mixed with it can be designed such that a water mist is present inside and outside the bowl arises, in which case the water or the water mixed with foaming agent is additionally mixed with a disinfectant. In this way, an effective, automatic disinfection of the toilet bowl, glasses and the area surrounding the toilet bowl is obtained. If the foam dissolver nozzles are under the normal pressure of the rinse water, pressure reducing valves are preferably arranged upstream of the nozzles, so that the introduction of the foam dissolver or the water mixed with foam dissolver and / or disinfectant is carried out under a pressure of only about 0.1 to 0 , 6 bar.

In the case of a seat closet with seat glasses, the "disinfection mist" mentioned not only produces disinfection of the same, but also a certain amount of moistening. This offers the z. B. in the United States customary paper pads on the seat a non-slip grip with simultaneous disinfection. 1 _S chlie _ß lic _h should also be mentioned at this point that, for the Ver ^¬ avoidance _d there spraying, in particular when using a _S aug _kl osetts, small bubble foams with a high weight of about 20 to 80 g / 1 are particularly effective.

The arrangement according to the invention is advantageously designed such that the flushing or pushbutton is connected to a lever arrangement in such a way that both the water flushing and the metering of the foaming agent and the foaming are triggered and controlled by the lever arrangement mentioned .

Of particular advantage is the arrangement according to claim 19 and / or 20, which, depending on the need, a rinse with or without

₁₅ foam, or with foam and flushing water from the flush valve and

Rinsing water from the cistern (rinsing water reservoir) allowed. These measures are particularly useful if the flush valve only has a max. 1/2 "water supply line is assigned. The foam formation is caused by the

Promoted _"n torn air while the actual purge is effected by the left hand in the cistern water. The dosage of the amount of foaming agent can be changed on the one hand according to claim 21, on the other hand by an adjustable stop for the button assigned to the dosing pump.

₅ The measures according to claim 22 are important for an "unbraked" flow of rinsing water into the bowl, the foaming agent reservoir and the like being furthermore as far away from the rinsing water outlet opening as possible.

30 In the case of the use of a foam dissolver, it is moreover expedient to install a forced coupling, which ensures that when the flushing or pushbutton is actuated, the foam dissolver dispensing device and only then the flushing water release valve are activated.

35 Exemplary embodiments of the invention are explained in more detail below with reference to the attached drawing. Show it:

1 shows an arrangement for generating foam in a toilet bowl using a pressure winder in schematic cross section; and

2 shows a foam generation and foam dissolving device accommodated in a pair of glasses in a seat lavatory, in plan view, in particular for use with a

Suction toilet.

It should be noted in advance that a foam carpet is first formed in the bowl before using a toilet. After using the lavatory, rinsing is carried out in the usual way, and the foam should also be rinsed away. In the case of toilets with almost complete replacement of the water volume during the rinsing process, no special measures are regularly required to wash away the foam. If, on the other hand, the construction of the toilet is such that the water volume is only partially exchanged, it is advantageous to spray or otherwise apply a foam dissolver, possibly only water, onto the introduced foam before triggering the rinsing process collapses. Instead of this, it is also possible first to rinse with water and then, if all of the foam has not been rinsed away, to introduce foam dissolver, after which it is rinsed with water. The spray and odor-inhibiting substance floating on the surface does not necessarily have to be foam, although foam is particularly advantageous since it can be renewed easily and inexpensively for every use. The use of foam or the foaming agent which gives it together with water also does not lead to environmental pollution, since there are nowadays foaming agents which are biodegradable. Instead of foaming, therefore, in principle, B. emulsions or gels or solid bodies can be used. _A nhan _d of FIG. 1 is now forming a foam film in a non-illustrated toilet bowl using a _h erkömmlichen Druckspulers 10 will be described in more detail. The flush valve 10 is connected to a terminal 11 for a not _d arge set pressure water pipe (s. Arrow 12) is provided and comprises a valve arrangement 13, which after actuation of a flushing or push button 14 in the direction of arrow 15 an associated outlet port 16 for a predetermined time opens. The flush valve 10 is a commercially available flush valve and therefore need not be described in more detail here.

The outlet opening 16 opens into a flushing water line 17 leading to the toilet bowl (not shown), which is widened in a funnel shape at the upper end, so that an annular gap 18 is formed between the flush valve outlet opening 16 on the one hand and the upper end of the flushing water line 17 on the other hand. Through this annular gap 18, ambient air is drawn into the flushing water line 17 during flushing in the manner of a water jet pump.

Below the annular gap 18 or the air inlet opening defined thereby, a foaming agent supply line 19 opens into the flushing water line 17, through which a predetermined amount of foaming agent can be added to the flushing water during flushing (see arrow 20). The foaming agent (arrow 20) is preferably introduced into the rinsing water line 17 at a distance of at least approximately 4 mm below the air inlet opening defined by the annular gap 18.

It has been shown that the sucked-in air promotes foam formation in the toilet bowl very considerably, so that only relatively small amounts of foaming agent are required to produce a sufficiently high foam carpet in the bowl. In systems without a flush valve, the air admixture can also be operated with overpressure, e.g. B. from a compressed air reservoir apparent during flushing. The foaming agent feed line is connected to a mechanically operated metering pump 21. The metering pump 21 is driven via a lever arrangement coupled with the flushing or pushbutton 14, consisting of a fork lever 24 which is pivotably mounted about a horizontal axis 22 in the direction of the double arrow 23. The fork section 25 arranged on one side, in FIG. 1 on the left side, is articulated on the flushing or pushbutton 14. On the other side, in FIG. 1 on the right side, of the pivot axis 22 of the lever 24, a metering pump actuating lever 26 is articulated (joint 27). By actuating the flushing or pushbutton 14, the metering pump actuating lever 26 is moved in the direction of the double arrow 28.

The dosing pump 21 is supplied with foaming agent through a suction line 29 (suction direction 30) which is immersed in a correspondingly assigned foaming agent reservoir 31. The line 29 thus defines the Ansa ^* ugseite and the conduit 19, the pressure side of the metering pump 21. Incidentally, it is at the metering pump 21 to a commercially available pump, so that a detailed description thereof is omitted. The foaming agent in the reservoir or container 31 is identified in FIG. 1 by the reference number 32. Preferably, a check valve according to claim 17 is arranged in line 19 with the function specified in claim 17.

The arrangement described is "encapsulated" within a sound-insulated container 33 with cover 34, ie. H. arranged sound-insulating. For this purpose, the container 33 and the lid 34 are soundproof on the inside

Layer 35, e.g. B. fiberglass mat lined. The section of the rinsing water line 17 led out of the container 33 is also covered with a sound-absorbing material 36. The arrangement described is therefore extremely low-noise, with the formation of the foam carpet in the toilet bowl (not shown) additionally contributing to reducing the noise level. In order to ensure the air supply to the flushing water line 17, an air opening 37 is provided in the cover 34, which is, however, filled with an air-permeable but sound-absorbing material in the form of a corresponding plug 38 made of glass or rock wool.

Instead of the metering pump 21, a metering valve can also be provided, which opens when the underpressure in the foaming agent supply line 19 is appropriately formed due to the flushing water flowing through the flushing water line 17, so that a predetermined amount of foaming agent is sucked out of the reservoir 31 becomes. In this solution, the lever arrangement 24, 25, 26, 27 described is superfluous. Furthermore, the last-mentioned construction is very suitable for merely hanging on the air inlet opening 18. For this purpose, the free end of the foaming agent supply line 19 is like a hook bent, with the free end of the foaming agent feed line 19 protruding into the air inlet opening or hooked into the flushing water line 17, so that the opening of the foaming agent feed line lies sufficiently below the air inlet opening 18. With appropriate dimensions, not even a metering valve is required. The reservoir 31 may e.g. B. in the form of a bottle. The suction line reaching to the bottom of the bottle is then hooked to the air inlet opening 18 ^* with its hook-shaped bent end lying outside the bottle, so that the opening of the suction line lies at least 4 mm below the air inlet opening.

The arrangement described can also be arranged within a conventional cistern, which is lined on the inside with sound-insulating material. Finally, the arrangement described can be arranged in accordance with claims 19 and / or 20 in a conventional cistern filled with rinsing water with the advantages described in more detail above. In addition, the measures according to claim 18 can also be provided at low line pressure.

An arrangement will now be described with reference to FIG. 2, as is particularly advantageous for suction toilets.

2 shows a top view of the glasses 38 for mounting on a commercially available toilet bowl, in particular for a suction toilet. A foam generating device arranged below these glasses 38 in a rear spectacle arch 310 is actually not recognizable in the top view and is therefore shown in dashed lines. The same applies to a foam dissolving device, which will be described in more detail below.

A water connection 39 coming from behind in the rear area of the glasses 38 is connected via a valve 40 to a mixer 41, which has an additional line to a storage container 42 for a foaming agent. The valve 40 is connected via ^'a signal line 43 with an electronic timing control unit 44 in connection. The valve 40 is connected via the mixer 41 operating in the manner of a water jet pump by means of very short connecting hoses 45, 46 to a spray or spray nozzle 48 directed against a foaming sieve arrangement 47. The foam sieve arrangement 47, the

The storage container 42, the valve 40 and the mixer 41 are accommodated in a rear curvature 49 of the glasses 38. The mouth of the foam sieve arrangement 47 is brought out on the output side via an angled tube 50 to the inner rim of the glasses in such a way that it extends radially into the inside of the glasses 38 and thus into the interior of a toilet bowl connected to it points. The foaming sieve arrangement can still. a blower in the manner of a hair dryer blower can be assigned such that the foam formation within the arrangement 47 takes place with the aid of air flow. For this purpose, the fan is arranged behind the spray or spray nozzle 48, so that the air flow past the nozzle 48 is directed towards the outlet opening of the arrangement 47 or towards the angle tube 50. The air intake opening is preferably covered by an air-permeable layer or mat made of glass or rock wool for noise reduction and air filtering.

A non-return valve 51 is arranged on the side of the storage container 42, the foaming agent being filled in via a filling hose extending laterally to the edge of the glasses and the non-return valve 51. This also serves to ventilate the storage container 42 and prevents liquid from escaping, for example when the glasses 38 are folded up.

^The water connection 39, which in principle can also point downwards or backwards, is connected to a water hose during operation. By opening the valve 40, water can flow through the mixer 41, concentrated foaming agent being sucked out of the storage container 42 and mixed. The mixed liquid then flows to the foam sieve arrangement 47, where foam is formed, which can flow via the angle tube 50 to the toilet bowl.

In an embodiment without a water connection, the mixer 41 is omitted; and the valve 40 is arranged directly between the reservoir 42 and the foaming sieve arrangement 47. A finished mixture of a foaming agent with a dilution liquid is then present in the storage container 42, the storage container 42 being able to be designed in the manner of a spray can or having a pump for generating the required spray pressure. A foam dissolving device is also arranged in the arch of the glasses. The valve 40 forms together with another valve 52 a common valve body which is connected to the water connection 40. The valve 52 is also connected to the time control unit 44 via a signal line 53. The outlet of the valve 52 is connected via a mixer 54 to a preferably rigid line 55, which is guided in the front curvature 56 of the glasses 38 along the edge of the glasses opening 57 for the most part. On this line 55, spray and spray nozzles 58, 59 and 60 are arranged on both sides of the spectacle opening 57 and in the front area, the spray openings of which point downwards into the interior of the toilet bowl. Furthermore, a reservoir 61 for a foam dissolver is fitted in the front curvature 56 in such a way that it encompasses the spectacle opening 57 while making maximum use of the available space. This reservoir 61 is on the one hand 'connected to the mixer 54 and on the other hand also has a check valve 62 which corresponds to the check valve 51 in terms of arrangement and mode of operation.

The control of the valves 40, 52 takes place, for. B. for a suction toilet as follows:

After initiating a flushing process, valve 52 is first opened for a predetermined time, e.g. B. 6 s long. During this time, foam dissolver is injected or sprayed through the nozzles 58, 59, 60 into the toilet bowl, dissolving the foam carpet and, if necessary, rotating it in such a way that the toilet paper placed on the foam carpet is on the underside of the foam carpet or in itself water below.

Then the water, including excrement and, if necessary, toilet paper, is suctioned off. This takes about 6 s. Afterwards or shortly before the end of the suction, for a predetermined time, e.g. B. for 2 s, the valve 40 is opened so that foaming agent gets into the mixer 41 and 47 foam is formed in the foam sieve arrangement. At the same time, if the fan described is present, it can be activated in order to promote foam formation. During this time, fully formed foam is introduced into the toilet bowl through the winding tube 50, which then spreads evenly up to the edge of the toilet bowl. The foam is designed so that the foam carpet remains for a predetermined time, e.g. B. 6 or more hours. The toilet is ready for a new use.

The time sequence described is specified by the time control unit 44 after the flushing button has been pressed. The time control unit 44 thus also controls the suction of the water loaded with excrement from the toilet bowl. However, this control is not absolutely necessary. • * _*

It then becomes the foam dissolver while the ^m i ' ^t excrement-laden water is being sucked out of the toilet bowl. However, this control is not absolutely necessary. The foam dissolver is then injected into the toilet bowl while the excrement-laden water is being sucked off, while the foam carpet is simultaneously dissolved. As explained, the suction process takes about 6 s. The injection of the foam dissolver takes just as long. A separate timing with the suction is therefore not absolutely necessary. Existing suction toilets can thus also be retrofitted with the arrangement described.

As has already been explained at the beginning, the spray nozzles 58, 59, 60 can be designed for the foam dissolver in such a way that they are nebulized both inside and outside the toilet bowl. Then a disinfectant is preferably added to the foam dissolver. The mist that settles on the glasses and in the vicinity of the toilet bowl then brings about a corresponding disinfection of the immediate surroundings of the toilet bowl. The valve 52 is preferably designed as a pressure reducing valve. Such can also be arranged downstream of the mixer 54, so that the liquid dissolving the foam is injected through the nozzles 58, 59, 60 only under a pressure of approximately 0.1 to 0.6 bar.

The construction according to FIG. 2 is preferably also assigned a cistern or rinsing water tank, which is not shown. According to the invention, this should always be filled with foam, as a result of which considerable noise damping is achieved. Foam formation preferably takes place in the cistern during the cistern emptying and / or during

Refill the cistern with fresh water. For this purpose, e.g. B. a hose connection between the Winkel¬ tube 50 and the cistern can be provided so that part of the foam formed in the foam sieve assembly 47 goes directly into the cistern. However, a separate foam-forming device is preferably assigned to the cistern.

The above thought thus includes the following features:

Introducing foam into the air space of the cistern and / or enriching the rinsing water with foam. This is preferably done by introducing rinse water enriched with foaming agent into the cistern for the purpose of foaming, while at the same time admitting the air required for foaming, or optionally by direct introduction of foam. With each rinse, the foam is supplemented by new formation or feed line and the degraded foam is drained into the sink. Advantageously, almost the entire air space in the cistern, including all angles of the installed fittings, is filled by utilizing the pressure on the foam supply floating thereon as the water supply in the cistern increases. 1 If the pressure in the rinsing water line is too high, there is a risk that the foam carpet that forms during rinsing will ^actually be washed away. In this case, it has proven to be advantageous to place a pressure-reducing valve in the flushing water line.

5 valve to integrate. This measure is both in connection with the described embodiments and also independently of that. H. particularly advantageous in connection with the embodiments according to PCT / EP 87/00178.

j_0 ^üπι To ^reliably prevent undesirable foam formation in the event of leaks in the closing valve associated with the flushing water line, a valve, in particular a non-return valve, can be assigned to the foaming agent supply line, which valve only starts from a predetermined opening pressure, in particular of more than 1 bar,

- _j _ opens. This measure is particularly advantageous if the foaming agent is sucked into the flushing water line by a kind of water jet pump effect.

Cattle stalls and pigsties are often with a so-called

20 slatted floors, i.e. with a slatted floor. Below this floor there is a pit into which the animal excretions fall through the gaps in the floor. The manure that accumulates in the pit in this way spreads a foul stench that spreads over the slatted floor

25 came out. If one wants to leakage of pit übelriechen¬ the materials and bacteria from such other ^~ -ϊer Jauche¬ prevent, can be seen in the pit or the like. Introduce a foam blanket, the lighter than liquid manure and from above is a descendant liquid manure and solid excrements permeable

30 is. This can be done in several ways, e.g. B. by entering a permanently installed or portable container for a foam agent. The foam carpet floats on the liquid manure and holds back the stench.
