Definitions
- a device for the automatic rinse water-controlled dispensing of a liquid cleaning agent into a toilet bowl is mainly known at the end of a flush, in which a product container arranged in the rinse water storage tank is rotatably mounted. It is designed so that it is in its rest position due to buoyancy of the rinsing water in the filled storage tank and rotates when the rinsing water level is lowered such that a metered amount of product is dispensed into the last half of the escaping rinsing water from its closure.
- This device has some disadvantages.
- the device can only dispense the product to be dosed into the last half of the rinse water, so it cannot prevent part of the dosed product from being carried away directly into the wastewater. This may make sense for a cleaning agent, which is why the claim of this utility model only refers to the supply of a cleaning agent.
- a cleaning agent e.g. Disinfectant or fragrance solutions
- a large part of the product would be discharged into the wastewater without any effect and thus unnecessarily pollute it. This disadvantage cannot be avoided with this device.
- Another, more important disadvantage is that it can only be installed in the cistern. These are very cumbersome to open and are becoming even more difficult to access due to increasing integration into the wall. It would therefore make more sense to develop a device that can simply be hung in the toilet bowl.
- the toilet sticks which have been produced in large numbers for many years, are known to be hung in the toilet bowl lying in a water-permeable container.
- a small part of the amount of rinsing water runs through the toilet stick and detaches some cleaning (or disinfectant) substance from the toilet stick and, to the grief of consumers and manufacturers, carries the substances with it into the wastewater.
- the toilet stick is perfumed, most of the perfume that has been rinsed off is also carried away into the wastewater, without having contributed to improving the air in the toilet. This fact naturally leads to violent attacks by those concerned with the environment. They recommend that you do without the products that can only be used to a very small extent. The situation is very similar for cistern additives.
- the total amount of water in a flushing process is enriched with the active substances, although they are flushed with the water through the toilet into the waste water in a matter of seconds and only a very small part in the Toilet bowl remains and can act there.
- the product container (1) consists of a hollow body (2), a spout (3) and a cap (4), which is located on this spout.
- the container (1) is filled with product up to level (10).
- the cap has two opposite openings (5), which are the only ones that ensure air exchange with the product container. They are attached so that when the product container is at rest (Fig. 1) they are to the right of the opening of the spout (3).
- the product container is located in a rinsing water collecting container (8a and 8b) divided into two containers by the partition (7).
- the product container can be rotated in point (6) in such a way that its upper part with spout and cap can turn 90 ° to the left.
- water flows into the two open containers (8a and 8b).
- some water runs out of the openings (9a and 9b) at the same time, but less than flows in from above. So the containers fill with water.
- the lower part of the product container is pushed upwards because it is hollow at the bottom.
- the anchorage in point (6) ensures that evasion before the buoyancy can only take place in such a way that rotation follows.
- the product container tilts back into its rest position (Fig. 3).
- some product had collected in the cap (4), which partly flows back into the product container via the spout during the tilting-back movement.
- Only the amount (less than 1 ml) that had been under the spout in the position in Fig. 2 no longer flows back into the product container, but via the lower opening (5) of the cap (4) into the water collecting container (8a ), which still contains a small amount of rinse water. Mixed with this, the product drops enter the toilet bowl. The required amount of product has been dosed. The process is repeated for the next rinse.
- the water collecting container is filled with water, the position of the product container is the same as in FIG. 8. It has already released the necessary amount of product into the product container. Only the water level that is above the product container should actually be symbolized.
- the water level in the storage tank drops very quickly. If it drops below the height of the dosing cap, the water collecting container runs empty, so that it becomes lighter again, can tip back and thereby releases the product into the remaining amount of rinsing water.
- the speed of the empty run is determined by the size of the outlet opening and is such that the collection container has become empty even before the water tank is emptied, so that the product container tilts back and doses product into the last part of the rinsing water to take it to the toilet bowl reach.

Abstract
Description
Aus dem Gebrauchsmuster G 84 33 563.7 ist ein Gerät zur automatischen spülwassergesteuerten Abgabe eines flüssigen Reinigungsmittels in ein Toilettenbecken hauptsächlich zum Ende einer Spülung bekannt, bei dem ein in dem Spülwasservorratstank angeordneter Produktbehälter drehbar gelagert ist. Er ist so gestaltet, daß er sich in seiner Ruhelage durch Auftrieb des Spülwassers in gefülltem Vorratstank befindet und sich bei Absenken des Spülwasserniveaus derart dreht, daß aus seinem Verschluß eine dosierte Menge Produkt in die letzte Hälfte des auslaufenden Spülwassers abgegeben wird.From the utility model G 84 33 563.7 a device for the automatic rinse water-controlled dispensing of a liquid cleaning agent into a toilet bowl is mainly known at the end of a flush, in which a product container arranged in the rinse water storage tank is rotatably mounted. It is designed so that it is in its rest position due to buoyancy of the rinsing water in the filled storage tank and rotates when the rinsing water level is lowered such that a metered amount of product is dispensed into the last half of the escaping rinsing water from its closure.
Dieses Gerät besitzt einige Nachteile.This device has some disadvantages.
In der vorliegenden Form kann das Gerät das zu dosierende Produkt immer nur in die letzte Hälfte des Spülwassers abgeben, kann also nicht verhindern, daß ein Teil des dosierten Produkts unmittelbar ins Abwasser mitgerissen wird. Für ein Reinigungsmittel mag das sinnvoll sein, weshalb im Anspruch dieses Gebrauchsmusters nur von der Abgabe eines Reinigungsmittels die Rede ist. Bei anderen Flüssigkeiten, wie z.B. Desinfektions- oder Duftlösungen, würde ein großer Teil des Produkts ohne Wirkung ins Abwasser geleitet werden und dieses damit unnötig belasten. Dieser Nachteil kann mit diesem Gerät nicht vermieden werden.In the present form, the device can only dispense the product to be dosed into the last half of the rinse water, so it cannot prevent part of the dosed product from being carried away directly into the wastewater. This may make sense for a cleaning agent, which is why the claim of this utility model only refers to the supply of a cleaning agent. For other liquids, e.g. Disinfectant or fragrance solutions, a large part of the product would be discharged into the wastewater without any effect and thus unnecessarily pollute it. This disadvantage cannot be avoided with this device.
Ein anderer, noch bedeutenderer Nachteil ist der, daß es nur im Spülkasten angebracht werden kann. Diese sind sehr umständlich zu öffnen und werden durch zunehmende Integration in die Wand noch schwieriger zugänglich. Es wäre deshalb sinnvoller, ein Gerät zu entwickeln, das einfach in das Toilettenbecken gehängt werden kann.Another, more important disadvantage is that it can only be installed in the cistern. These are very cumbersome to open and are becoming even more difficult to access due to increasing integration into the wall. It would therefore make more sense to develop a device that can simply be hung in the toilet bowl.
Das zitierte Gebrauchsmuster funktioniert nicht im Toilettenbecken.The utility model cited does not work in the toilet bowl.
Mit Anmeldung DE-U-89 02 509 ist ein Gerät bekannt, das eine etwas kleinere untere Auslauföffnung aufweist, um verzögert etwas Spülwasser ins Toilettenbecken abzugeben, das den im Auffangbehälter positionierten WC-Stick umspült hat. Dieses Gerät löst aber auch während der Spülung Teile vom WC-Stick und reißt sie mit ins Abwasser.With application DE-U-89 02 509 a device is known which has a somewhat smaller lower outlet opening in order to delay delivering some flushing water into the toilet bowl, which has washed around the toilet stick positioned in the collecting container. However, this device also detaches parts from the toilet stick during rinsing and pulls them into the wastewater.
In Europa ist außerdem der Markt für Wasserkastenadditive nur 10% von dem, was für die Anbringung im Toilettenbecken konzipiert ist.In Europe, the water box additive market is only 10% of what is designed to be installed in the toilet bowl.
Ferner sind die seit vielen Jahren in großen Stückzahlen produzierten WC-Sticks bekannt, die, in einem wasserdurchlässigen Behältnis liegend, in das Toilettenbecken gehängt werden. Wird gespült, läuft ein kleiner Teil der Spülwassermenge über den WC-Stick und löst hierbei etwas reinigende (oder auch desinfizierende) Substanz vom WC-Stick herunter und reißt zum Kummer der Verbraucher und Hersteller die Substanzen mit ins Abwasser. Nur ein kleiner Teil, nämlich der, der im Toilettenbecken verbleibt, kann zur Desinfektion in der Toilette beitragen.
Ist der WC-Stick parfümiert, wird ebenfalls der größte Teil des abgespülten Parfüms mit ins Abwasser gerissen, ohne zur Luftverbesserung in der Toilette beigetragen zu haben. Diese Tatsache führt naturgemäß zu heftigen Angriffen der Umweltbesorgten. Diese empfehlen, auf die nur zu einem sehr geringen Teil nutzbaren Produkte ganz zu verzichten. Bei den Spülkastenadditiven ist die Situation sehr ähnlich.Furthermore, the toilet sticks, which have been produced in large numbers for many years, are known to be hung in the toilet bowl lying in a water-permeable container. When flushing, a small part of the amount of rinsing water runs through the toilet stick and detaches some cleaning (or disinfectant) substance from the toilet stick and, to the sorrow of consumers and manufacturers, carries the substances with it into the wastewater. Only a small part, namely the one that remains in the toilet bowl, can contribute to disinfection in the toilet.
If the toilet stick is perfumed, most of the perfume that has been rinsed off is also carried away into the wastewater, without having contributed to improving the air in the toilet. This fact naturally leads to violent attacks by those concerned with the environment. They recommend that you do without the products that can only be used to a very small extent. The situation is very similar for cistern additives.
Auch hier wird die gesamte Wassermenge eines Spülvorgangs mit den Wirksubstanzen angereichert, obwohl sie in Sekundenschnelle mit dem Wasser durch das Klosett ins Abwasser gespült werden und nur ein sehr kleiner Teil im WC-Becken verbleibt und dort wirken kann.Here, too, the total amount of water in a flushing process is enriched with the active substances, although they are flushed with the water through the toilet into the waste water in a matter of seconds and only a very small part in the Toilet bowl remains and can act there.
Es wäre also wünschenswert, ein Gerät zu entwickeln, das die Wirksubstanzen erst nach der Spülung ins Toilettenbecken abgibt, so daß diese dann bis zur nächsten Spülung wirken können. Die Wirksubstanzen würden erst dann ins Abwasser gelangen, wenn sie ihre Aufgabe erfüllt haben. Das hätte eine sehr wesentliche Verminderung der Abwasserbelastung zur Folge. Wenn es dann noch gelingt, die Abgabe der Wirksubstanz so mit einem Spülvorgang zu koppeln, daß nach jeder Spülung automatisch die Wirksubstanz ins Toilettenbecken abgegeben wird, ist der ideale Reiniger, Desinfizierer und Luftverbesserer für die Toilette gefunden.
Das Gerät nach Anspruch 1 erfüllt diese Aufgabe und ist zudem noch mit sehr geringen Produktionskosten herstellbar.It would therefore be desirable to develop a device that only releases the active substances into the toilet bowl after flushing, so that they can then act until the next flush. The active substances would only get into the wastewater when they had fulfilled their task. This would result in a very substantial reduction in wastewater pollution. If it is then still possible to couple the delivery of the active substance with a flushing process so that the active substance is automatically released into the toilet bowl after each flush, the ideal cleaner, disinfectant and air freshener for the toilet has been found.
The device according to
Funktionsweise des bestimmungsgemäßen Geräts, das im Anspruch 1 dargestellt wird.Operation of the intended device, which is presented in
Der Produktbehälter (1) besteht aus einem Hohlkörper (2), einem Ausgießer (3) und einer Kappe (4), die sich auf diesem Ausgießer befindet. Der Behälter (1) ist bis zum Niveau (10) mit Produkt gefüllt. Die Kappe weist zwei gegenüberliegende Öffnungen (5) auf, die als einzige den Luftaustausch mit dem Produktbehälter sicherstellen. Sie sind so angebracht, daß sie bei der Ruhestellung des Produktbehälters (Fig.1) sich rechts von der Öffnung des Ausgießers (3) befinden.The product container (1) consists of a hollow body (2), a spout (3) and a cap (4), which is located on this spout. The container (1) is filled with product up to level (10). The cap has two opposite openings (5), which are the only ones that ensure air exchange with the product container. They are attached so that when the product container is at rest (Fig. 1) they are to the right of the opening of the spout (3).
Der Produktbehälter befindet sich in einem durch die Trennwand (7) in zwei Behälter aufgeteilten Spülwassersammelbehälter (8a u. 8b). Der Produktbehälter ist im Punkt (6) in der Weise drehbar, daß sich sein oberer Teil mit Ausgießer und Kappe um 90° nach links drehen kann.
Wird gespült, fließt Wasser in die beiden oben offenen Behälter (8a u. 8b). Während des gesamten Spülvorgangs läuft auch gleichzeitig aus den Öffnungen (9a u. 9b) etwas Wasser heraus, aberweniger als von oben hineinfließt. Die Behälter füllen sich also mit Wasser. Das hat zur Folge, daß der untere Teil des Produktbehälters nach oben gedrückt wir, weil er unten hohl ist. Die Verankerung im Punkt (6) sorgt dafür, daß ein Ausweichen vor dem Auftrieb nur so erfolgen kann, daß eine Drehung folgt. Der Produktbehälter kippt mit seinem oberen linken Teil so weit nach links, daß Ausgießer und Kappe den tiefsten Punkt bilden. In dieser Position (Fig.2) kann kein Ausgießen erfolgen, weil die beiden Öffnungen (5) in der Kappe (4) höher liegen als die Öffnung des Ausgießers (3) und dadurch die Flüssigkeit im Produktbehälter einen Luftaustausch verhindert.
Bis zur Beendigung des Spülvorgangs bleibt der Produktbehälter in dieser Position.
Ist der Spülvorgang beendet, wird von oben kein Spülwasser mehr in die Sammelbehälter (8a u. 8b) gebracht, so daß das Spülwasser nur noch unten herausläuft, und zwar aus dem rechten Behälter schneller als aus dem linken, weil die Öffnung (9b) größer ist als die Öffnung (9a).The product container is located in a rinsing water collecting container (8a and 8b) divided into two containers by the partition (7). The product container can be rotated in point (6) in such a way that its upper part with spout and cap can turn 90 ° to the left.
When rinsing, water flows into the two open containers (8a and 8b). During the entire rinsing process, some water runs out of the openings (9a and 9b) at the same time, but less than flows in from above. So the containers fill with water. As a result, the lower part of the product container is pushed upwards because it is hollow at the bottom. The anchorage in point (6) ensures that evasion before the buoyancy can only take place in such a way that rotation follows. The upper left part of the product container tilts so far to the left that the spout and cap form the lowest point. In this position (Fig. 2) no pouring can take place because the two openings (5) in the cap (4) are higher than the opening of the pourer (3) and the liquid in the product container thereby prevents air exchange.
The product container remains in this position until the rinsing process has ended.
When the rinsing process is finished, no more rinsing water is brought into the collection containers (8a and 8b) from above, so that the rinsing water only runs out from below, faster from the right container than from the left because the opening (9b) is larger is as the opening (9a).
Der Produktbehälter kippt in seine Ruhestellung zurück (Fig.3). Während der Position in Fig.2 hatte sich in der Kappe (4) etwas Produkt gesammelt, welches bei der Rückkippbewegung zum Teil wieder über den Ausgießer in den Produktbehälter zurückfließt. Nur die Menge (weniger als 1ml), die sich bei der Lage in Fig.2 unter dem Ausgießer befunden hatte, fließt nicht mehr in den Produktbehälter zurück, sondern über die untere Öffnung (5) der Kappe (4) in den Wassersammelbehälter (8a), der noch eine kleine Menge Spülwasser enthält. Mit dieser vermischt, gelangen die Produkttropfen in das Toilettenbecken.
Es ist die gewünschte Menge Produkt dosiert worden.
Bei der nächsten Spülung wiederholt sich der Vorgang.The product container tilts back into its rest position (Fig. 3). During the position in FIG. 2, some product had collected in the cap (4), which partly flows back into the product container via the spout during the tilting-back movement. Only the amount (less than 1 ml) that had been under the spout in the position in Fig. 2 no longer flows back into the product container, but via the lower opening (5) of the cap (4) into the water collecting container (8a ), which still contains a small amount of rinse water. Mixed with this, the product drops enter the toilet bowl.
The required amount of product has been dosed.
The process is repeated for the next rinse.
Es gibt noch andere Möglichkeiten, die Kippbewegung des Produktbehälters während der Spülung mit Hilfe des Spülwassers hervorzurufen, bzw. den Dosiervorgang anders durchzuführen.
- 1) andere Dosiermöglichkeiten:
- a) mit feinporigem porösem Kunststoff (Fig. 4)
In Fig. 1 - 3 tritt an die Stelle des Ausgießers (3) ein feinporiger, poröser Kunststoff, dessen Porigkeit auf die Viskosität des Produkts in der Weise abgestimmt ist, daß bei gekippter Position des Produktbehälters (1) (Fig. 2) durch diesen Kunststoff innerhalb von 4Sekunden 0,1 ml Produkt heraustropft. Diese Produktmenge sammelt sich in der Kappe (4) und tropft nach dem Zurückkippen aus ihr heraus. - b) mit Roll-on-Prinzip
In Fig. 5 und 6 ist ein oben mit einer Roll-on-Kugel verschlossener Produktbehälter (1) gezeigt, der unten einen kleinen Hohlraum (2) aufweist. Die Roll-on-Kugel ist am Wassersammelbehälter (15) fixiert, so daß sie sich nicht bewegen kann. An ihr hängt der Produktbehälter und schließt ihn durch sein Eigengewicht. Mit (10) ist das Flüssigkeitsniveau des Produkts im Produktbehälter symbolisiert. Wird gespült, sammelt sich Wasser im Wassersammelbehälter (8). Der Produktbehälter fängt an zu schwimmen und wird um 90° nach oben um die Achse der Roll-on-Kugel verdreht (Fig. 6). Das Produkt fließt gegen die Kugel und sammelt sich in geringer Menge in der kleinen Ausbuchtung (16) auf der Kugel. Nach der Spülung fließt das Spülwasser wieder bei (9) aus dem Sammelbehälter heraus, der Produktbehälter geht wieder in die ursprüngliche Stellung zurück (Fig. 5). Das auf dem kleinen Hohlraum der Roll-on-Kugel (16) gesammelte Produkt liegt jetzt frei und wird von dem Wasser aus dem kleinen Wassersammelbehälter (8c) oberhalbgder Roll-on-Kugel freigespült und fließt von dort mit dem Spürwasser in das Toilettenbecken.
- a) mit feinporigem porösem Kunststoff (Fig. 4)
- 2) Kippen des Produktbehälters auf andere Art.
- a) Wassersammelbehälter auf dem Produktbehälter. (Fig. 7,8,9) Das Gerät besteht aus dem gleichen Produktbehälter (1) wie in Figur 1 - 3 beschrieben, nur der Wasserauffangbehälter ist anders, viel kleiner ausgebildet, und befindet sich fest verankert auf demmlinken oberen Teil des Produktbehälters. Die Dosierung über den Auslaufstutzen (3) und die Dosierkappe (4) erfolgt in gleicher Weise wie oben beschrieben, d.h. nach dem Zurückkippen in die Ruheposition fließt der Produkttropfen zur unteren Auslauföffnung der Dosierkappe.
Der Kippmechanismus wird allerdings anders bewirkt, weil der trichterförmige Wassersammelbehälter (jetzt Nr. 20) anders ausgebildet und anders angebracht ist. (Fig. 7)
Er befindet sich oberhalb der Dosierkappe und ist dort fest mit dem Produktbehälter (1) verbunden, sammelt während der Spülung durch seine rechte Öffnung (21) Spülwasser, wird wegen des Wassergewichts schwerer und kippt nach unten, was sich für den Produktbehälter (1) als Drehung um 90° auswirkt. Ein Kippen ist nur bis 90° möglich, was auf verschiedene Weise gewährleistet werden kann, z.B. dadurch, daß sich in der Nähe der Drehachse am Produktbehälter ein Dorn befindet, der beim Kippen dann gegen den Aufhängbügel schlägt, wenn der Produktbehälter um 90° nach links gedreht wurde. Der Produktbehälter befindet sich jetzt in derPosition der Figur 8. Aus dem Auffangbehälter kann über die untere Öffnung (22) Spülwasser entweichen. Es läuft hier wie oben beschrieben, aus der unteren Öffnung weniger heraus als über die obere hineinfließt. Der Produktbehälter (1) bleibt also während des gesamten Spülvorgangs in derPosition der Figur 8.
Ist die Spülung beendet, läuft der Spülwasserauffangbehälter leer, wird leichter, der Produktbehälter kippt zurück, die zu dosierende Menge Produkt tritt aus der unteren Öffnung der Dosierkappe aus und wird von der Restmenge Spülwasser aus dem Auffangbehälter abgespült.
InFigur 9 ist eine Vorderansicht des Produktbehälters (1) mit aufgesetztem Wasserauffangbehälter (20) dargestellt. Die dort skizzierte Öffnung (23) ist die Entlüftungsöffnung für die Dosierung. - b) Widerstand gegen den Strom der Wasserspülung.
Handelt es sich bei dem in Fig. 7 - 9 als Wasserauffangbehälter (20) bezeichneten Teil nicht um einen Hohlraum der bei (21) offen ist, sondern an dieser Stelle geschlossen wurde, so muß man dies als einen Teil ansehen, der einen Widerstand im Wasserstrom des Spülwassers darstellt, besonders dann, wenn die Seiten der ursprünglichen Öffnung noch parallel zur Behälterwandung mit Wandungen versehen sind, so daß das Wasser, das gegen den Widerstand fließt nicht einfach an der Seite vorbeiströmen kann. Das hat dann zur Folge, daß dann bei der Spülung das Spülwasser diesen Widerstand nur dadurch verkleinern kann, daß es den Produktbehälter um 90° nach links kippt. Die Achse, um die der Produktbehälter kippen kann, ist so beschaffen, daß der Produktbehälter zurückkippt, wenn der Druck des Spülwassers nicht mehr vorhanden ist.
Natürlichn kann dieser Widerstand im Wasserstrom auch anders am Produktbehälter angebracht sein als hier beschrieben, wichtig ist nur, daß der Widerstand im der Ruhestellung größer ist als wenn sich der Behälter um 90° nach links gedreht hat.
- a) Wassersammelbehälter auf dem Produktbehälter. (Fig. 7,8,9) Das Gerät besteht aus dem gleichen Produktbehälter (1) wie in Figur 1 - 3 beschrieben, nur der Wasserauffangbehälter ist anders, viel kleiner ausgebildet, und befindet sich fest verankert auf demmlinken oberen Teil des Produktbehälters. Die Dosierung über den Auslaufstutzen (3) und die Dosierkappe (4) erfolgt in gleicher Weise wie oben beschrieben, d.h. nach dem Zurückkippen in die Ruheposition fließt der Produkttropfen zur unteren Auslauföffnung der Dosierkappe.
- 3) Einsatz im Wasserkasten der Toilette.
Das Gerät kann, wie in Fig. 7 - 9 beschrieben ohne irgend eine Veränderung der Teile auch im Toiletten- Wasserkasten eingesetzt werden und funktioniert in gleicher Weise, daß also erst am Ende der Spülung Produkt dosiert wird.
Die Dosierung geschieht dann folgendermaßen:
Der Produktbehälter (1) incl. Wasserauffangbehälter (20) befinden sich in der Ruhestellung unterhalb des Wasserspiegels.
- 1) other dosing options:
- a) with fine-pored porous plastic (Fig. 4)
In Fig. 1-3, the spout (3) is replaced by a fine-pored, porous plastic, the porosity of which is matched to the viscosity of the product in such a way that when the product container (1) (Fig. 2) is in a tilted position Plastic drips out 0.1 ml of product within 4 seconds. This amount of product collects in the cap (4) and drips out of it after tipping back. - b) with roll-on principle
5 and 6 show a product container (1) which is closed at the top with a roll-on ball and which has a small cavity (2) at the bottom. The roll-on ball is fixed to the water collecting container (15) so that it cannot move. The product container hangs on it and closes it by its own weight. (10) symbolizes the liquid level of the product in the product container. When rinsing, water collects in the water collection container (8). The product container begins to swim and is rotated 90 ° upwards around the axis of the roll-on ball (Fig. 6). The product flows against the ball and collects in small quantities in the small bulge (16) on the ball. After rinsing, the rinsing water flows out of the at (9) Collect the container, the product container returns to its original position (Fig. 5). The product collected on the small cavity of the roll-on ball (16) is now exposed and is flushed away by the water from the small water collecting container (8c) above the roll-on ball and flows from there with the tracer water into the toilet bowl.
- a) with fine-pored porous plastic (Fig. 4)
- 2) Tilt the product container in a different way.
- a) Water collecting container on the product container. (Fig. 7,8,9) The device consists of the same product container (1) as described in Figures 1-3, only the water collecting container is different, much smaller, and is firmly anchored on the left upper part of the product container. Dosing via the outlet nozzle (3) and the dosing cap (4) is carried out in the same way as described above, ie after tipping back into the rest position, the product drop flows to the lower outlet opening of the dosing cap.
The tilting mechanism is effected differently, however, because the funnel-shaped water collection container (now No. 20) is designed differently and attached differently. (Fig. 7)
It is located above the dosing cap and is firmly connected to the product container (1), collects rinsing water through its right opening (21) during rinsing, becomes heavier due to the water weight and tilts down, which is suitable for the product container (1) Rotation by 90 °. Tilting is only possible up to 90 °, which can be ensured in various ways, e.g. by having a mandrel near the axis of rotation on the product container, which then tilts against the suspension bracket when the product container is tilted 90 ° to the left was filmed. The product container is now in the position of FIG. 8. Rinsing water can escape from the collecting container through the lower opening (22). It runs here as described above, flows out of the lower opening less than through the upper one. The product container (1) therefore remains in the position in FIG. 8 during the entire rinsing process.
When the rinsing is finished, the rinsing water collecting container runs empty, becomes lighter, the product container tilts back, the quantity of product to be dosed comes out of the lower opening of the dosing cap and is rinsed off the remaining quantity of rinsing water from the collecting container.
FIG. 9 shows a front view of the product container (1) with the water collecting container (20) attached. The opening (23) outlined there is the ventilation opening for metering. - b) Resistance to the flow of water flushing.
If it is in the part in Fig. 7 - 9 designated as a water collecting container (20) not a cavity which is open at (21), but was closed at this point, this must be regarded as a part that has a resistance in Water flow of the rinsing water, especially if the sides of the original opening are still provided with walls parallel to the container wall, so that the water that flows against the resistance can not simply flow past the side. The result of this is that the rinsing water during rinsing can only reduce this resistance by tilting the product container 90 ° to the left. The axis around which the product container can tilt is such that the product container tilts back when the pressure of the rinsing water is no longer present.
Of course, this resistance in the water flow can also be attached to the product container differently than described here, it is only important that the resistance in the rest position is greater than when the container has rotated 90 ° to the left.
- a) Water collecting container on the product container. (Fig. 7,8,9) The device consists of the same product container (1) as described in Figures 1-3, only the water collecting container is different, much smaller, and is firmly anchored on the left upper part of the product container. Dosing via the outlet nozzle (3) and the dosing cap (4) is carried out in the same way as described above, ie after tipping back into the rest position, the product drop flows to the lower outlet opening of the dosing cap.
- 3) Use in the toilet water box.
As described in FIGS. 7-9, the device can also be used in the toilet water tank without any change in the parts and functions in the same way, that is, product is only metered at the end of the flushing.
The dosage then happens as follows:
The product container (1) including the water collecting container (20) are in the rest position below the water level.
Der Wasserauffangbehälter ist in diesem Zustand mit Wasser gefüllt, die Position des Produktbehälters ist die gleiche wie in Figur 8. Er hat die notwendige Menge Produkt bereits in den Produktbehälter abgegeben. Es müßte eigentlich nur der Wasserspiegel symbolisiert werden, der sich oberhalb des Produktbehälters befindet. Während der Spülung sinkt der Wasserspiegel im Vorratstank sehr schnell ab. Sinkt er unter die Höhe der Dosierkappe, läuft der Wassersammelbehälter leer, so daß er wieder leichter wird, zurückkippen kann und dabei das Produkt in die Restmenge Spülwasser abgibt. Die Geschwindigkeit des Leerlaufens wird durch die Größe der Auslauföffnung bestimmt und ist so beschaffen, daß der Sammelbehälter noch vor der Entleerung des Wasserkastens selbst leer geworden ist, damit der Produktbehälter zurückkippt und Produkt in den letzten Teil des Spülwassers dosiert, um mit ihm ins Toilettenbecken zu gelangen.In this state, the water collecting container is filled with water, the position of the product container is the same as in FIG. 8. It has already released the necessary amount of product into the product container. Only the water level that is above the product container should actually be symbolized. During the flushing, the water level in the storage tank drops very quickly. If it drops below the height of the dosing cap, the water collecting container runs empty, so that it becomes lighter again, can tip back and thereby releases the product into the remaining amount of rinsing water. The speed of the empty run is determined by the size of the outlet opening and is such that the collection container has become empty even before the water tank is emptied, so that the product container tilts back and doses product into the last part of the rinsing water to take it to the toilet bowl reach.
Claims (7)
- A dosing device for the dosed dispensation, controlled by the flushing water, of a disinfecting, cleaning, fragrant or other fluid into a WC bowl, comprising a perpendicularly tiltably arranged fluid container (1) provided with a single opening, and a dosing means (4), wherein the tilting of the fluid container (1) from an emptying position of the dosing means (4) to a filling position of the dosing means (4) takes place by means of the buoyancy force of the flushing water and, in the opposite direction, by the disappearance of the buoyancy force, characterized in that the dosing device is arranged in a collecting container (8a, 8b; 8) for flushing water in such a way that the flushing water flowing into the WC bowl fills the collecting container (8a, 8b; 8), and that the collecting container (8a, 8b; 8) comprises a large filling opening at the top and at least one small outlet opening (9a, 9b; 9) at the bottom which causes a delayed emptying of the collecting container (8a, 8b; 8) and thus a delayed achievement of the emptying position of the dosing means (4; 14), and
that the dosing means (4) is formed as a dosing cap which is arranged at an outlet connection piece (3) located at the opening of the fluid container (1) and which comprises two opposite openings (5) which are arranged adjacent to the edge of the opening of the dosing cap, one of said openings serving as an outlet opening in the emptying position and the second opening serving as an aeration opening and which are both located above the extremity of the outlet connection piece (3) when the dosing cap is in the filling position so that the dosed amount flown into the dosing cap in the filling position blocks a further flow from the fluid container. - The dosing device according to claim 1, characterized in that the dosing means is formed as a small cavity (16) on a roll-on ball (14) fixed (15) at the flushing water collecting container (8) and connected with the perpendicularly tiltable fluid container (1) via a fitment (17) in such a way that the fluid container (1) is located on the bottom of the collecting container (8) in the emptying position and closes the fluid container (1) due to its own weight by means of the roll-on ball (14), that, when the collecting container (8) is filled, the fluid container (1) is moved due to the buoyancy force into a position tilted 90° upwards which represents the filling position, that subsequently product is dispensed into the small cavity (16), that the fluid container (1) returns to the emptying position when the collecting container (8) is emptied after the flushing causing the small cavity (16) to be released, and that flushing water drops from the additional collecting container (8c) and rinses the dosed amount of fluid from the small cavity (16).
- The dosing device according to claim 1 and 2, characterized in that the single opening of the liquid container (1) is provided with a fine pored and porous film whose porosity is such that it releases 0.01 to 0.5 ml within 4 seconds during tilting.
- The dosing device according to claims 1 to 3, characterized in that the collecting container (8a, 8b; 8) which is open at the bottom is fixed on the fluid container (1) in such a way that the water collected during the flushing renders the fluid container (1) so heavy that it tilts 90° to the left, remains in this position during the whole flushing, is emptied after the flushing so that it becomes lighter and tilts back.
- The dosing device according to any one of claims 1 to 3, characterized in that the collecting container comprises a dividing wall (7) which separates a first container (8a) from a second container (8b).
- The dosing device according to claim 5, characterized in that the first container (8a) comprises a first opening (9a) and the second container (8b) comprises a second opening (9b), the second opening (9b) being larger than the first opening (9a).
- The dosing device according to claim 5 or 6, characterized in that the fluid container is arranged in such a manner that the dosed amount is supplied into the first container.
