Abstract

A device for automatically dispensing a cleaning, perfumed, disinfectant and/or other solution into a toilet bowl after each flushing comprises a vertically sliding rod (4) provided with a notch (5). In its rest position, the rod (4) and its notch (5) lie outside a container containing a solution of active substance. During flushing, the rod (4) and its notch (5) are inserted into the product container (2). To this end, for example, a water collecting container with a wide open top and a small opening (7) at the bottom is filled during flushing with a volume of water such that a float (3) rigidly connected to the rod (4) is displaced upward by the upthrust, together with the rod (4). Alternatively, the flushing water or the flushing water current presses on a wing (16) which is connected, but not completely rigidly, through a hinge (17) with a rod (12) and forces the rod (12) into its lower position against the force of a spring (14), which as a result of the hinge (17) means the upper position of the rod (12). In this position, the notches (5) are located inside the active substance container (2), and therefore after flushing this rod (4) is again located in its lower position in which the notches (5) are located outside the active substance container (2). This occurs, on the one hand, because the water has run out of the collecting container, and thus the float (3) together with the rod (4) has moved down or, on the other hand, because the pressure of the spring (14) on the wing (16) again forces the wing (16) upward and hence the rod (12) down, i.e. with its notches (5) outside the active substance container (2). The result in each case is that in the upper position the notches (5) on the rod (4) have been filled with active substance which they dispense when they are located outside the active substance container (2).

Description

Die Erfindung betrifft ein Gerät zur spülwassergesteuerten automatischen Abgabe einer Wirkstoffflüssigkeit in einer definierten Menge in das Toilettenbecken nach jeder Spülung. Aus der deutschen Offenlegungsschrift 21 00 79 5 ist bereits eine Vorrichtung bekannt, die nach jedem Spülvorgang eine Menge einer Wirkstofflösung in das Toilettenbecken abgibt, wobei ein Rohr in die Spülwasserleitung hineingebracht wer­den muß, um einen Teil des Spülwasserstroms zur Betätigung von Schließorganen zu benutzen, welche Verbindungsöffnungen zwischen einem Wirkstoffbehälter und einer Dosierkammer einerseits sowie Dosierkammer und Verbindungsrohr anderer­seits verschließen. Die auf diese Weise durchgeführte Wirk­stoffdosierung hat die folgenden wesentlichen Nachteile: Das Verbindungsrohr kann nur von einem Fachmann in der Spül­wasserleitung installiert werden. Die Vorrichtung ist auf­wendig und durch den relativ hohen Materialaufwand speziell bei der beweglichen Trennwand zwischen Druck- und Dosierkam­mer auch verschleißanfällig.The invention relates to a device for the automatic dispensing of an active substance liquid in a defined amount into the toilet bowl after each flush. From the German laid-open specification 21 00 79 5, a device is already known which releases a quantity of an active ingredient solution into the toilet bowl after each flushing process, a tube having to be introduced into the flushing water line in order to use part of the flushing water flow to actuate closing elements, which Seal the connection openings between an active substance container and a dosing chamber on the one hand and the dosing chamber and connecting tube on the other. The active ingredient metering carried out in this way has the following major disadvantages: The connecting tube can only be installed by a specialist in the flushing water line. The device is complex and, due to the relatively high cost of materials, especially in the case of the movable partition between the pressure and metering chambers, is also prone to wear.

Der Erfindung liegt die Aufgabe zugrunde, ein Gerät der ein­gangs genannten Art so zu entwickeln, daß es einfach einsetz­bar und wirtschaftlich herstellbar ist und eine geringe Ver­schleißanfälligkeit aufweist.The invention has for its object to develop a device of the type mentioned so that it is easy to use and economical to manufacture and has a low susceptibility to wear.

Diese Aufgabe wird durch die im kennzeichnenden Teil des An­spruchs 1 gegebenen Merkmale gelöst.This object is achieved by the features given in the characterizing part of claim 1.

Besondere Ausgestaltungen des erfindungsgemäßen Geräts sind in den Unteransprüchen 2 bis 6 beschrieben.Particular configurations of the device according to the invention are described in subclaims 2 to 6.

Die Erfindung wird durch in der Zeichnung schematisch darge­stellte Ausführungsbeispiele näher erläutert.The invention is explained in more detail by exemplary embodiments shown schematically in the drawing.

Funktionsweise eines bestimmungsgemäßen GerätsFunctionality of an intended device

  • Figur 1 und 2 zeigen einen Längsschnitt durch das Gerät.Figures 1 and 2 show a longitudinal section through the device.
  • Figur 3 zeigt eine Seitenansicht und Figur 4 eine Drauf­sicht.Figure 3 shows a side view and Figure 4 shows a plan view.

Das Gerät selbst besteht aus einem oben weit und unten etwas offenen (7) Wassersammelbehälter und einem in sich geschlossenen Lösungsbehälter (2), aus dem unten ein Stab(4) mit Kerben (5) herausragt, der seinerseits starr mit einem Schwimmer (3) verbunden ist. Die Stützen (6) sollen ein gleichmäßiges Auf und Ab des Stabes (4) ge­währloisten. Der Lösungsbehälter ist durch Halterungsstüt­zen fest mit dem Sammelbehälter verbundem.(8)The device itself consists of a water tank that is slightly open at the top and bottom (7) and a self-contained solution tank (2), from which a rod (4) with notches (5) protrudes, which in turn is rigid with a float (3) connected is. The supports (6) should ensure a smooth up and down of the rod (4). The solution container is firmly connected to the collection container by means of support supports. (8)

Figur 1 zeigt das Gerät in Ruhestellung, so wie es im Toilettenbecken hängt. Wird nun gespült, füllt sich der Wassersammelbehälter mit Wasser. Obwohl Wasser durch die Öffnung (7) herauslaufen kann, ist der Behälter trotzdem schnell gefüllt, weil oben mehr hineinkommt als unten herausläuft.Figure 1 shows the device in the rest position, as it hangs in the toilet bowl. If you now rinse, the water collection container fills with water. Although water can run out through the opening (7), the container is still filled quickly because more comes in at the top than runs out at the bottom.

Hat der Wasserspiegel das Niveau der Bälle des Schwimmers (3) erreicht, so wird bei weiterem Steigen durch den Auf­trieb der Schwimmer nach oben gedrückt und damit gleich­zeitig ein Teil des Stabes (4) in den Lösungsbehälter hin­eingedrückt. Ist der Wasserspiegel bis zum oberen Rand des Sammelbehälters gekommen, hat der Schwimmer (3) seine höchstt­mögliche Position erreicht und den Stab (4) soweit in den Lösungsbehälter (2) hineingedrückt, wie es die Stabführungs­stützen (6) zulassen. Die Kerbe (5) am Stab befindet sich im Lösungsbehälter und nimmt dort Produkt auf.When the water level has reached the level of the balls of the float (3), the float is pushed upwards by the buoyancy as it rises further and at the same time a part of the rod (4) is pressed into the solution container. When the water level has reached the upper edge of the collecting tank, the float (3) has reached its highest possible position and pushed the rod (4) into the solution tank (2) as far as the rod guide supports (6) allow. The notch (5) on the rod is in the solution container and takes up product there.

Dieser Zustand ist in Figur 2 widergegeben.This state is shown in Figure 2.

Läuft der Wassersammelbehälter nach der Spülung leer, sinkt der Schwimmer und mit ihm der Stab. Ist der Wasser spiegel gerade unterhalb der Nullposition der Bälle des Schwimmers (3), (wie in Figur 1 dargestellt), ist die Menge Product die sich in der Kerbe gesammelt hatte, in der Rest­menge Wasser gelöst und fließt mit dem Wasser in das Toilet­tenbecken und kann dort bis zur nächsten Spülung seine Auf­gabe(n) erfüllen.If the water reservoir runs empty after flushing, the float sinks and with it the rod. If the water level is just below the zero position of the float balls (3) (as shown in Figure 1), the amount of product that has collected in the notch is dissolved in the remaining amount of water and flows with the water into the toilet bowl and can fulfill its task (s) there until the next flush.

  • Fig. 6 shows the state during the rinse

Das geschlossene Gerät 11 wird mit Wirkstoff gefüllt in das Toilettenbecken gehängt und nimmt dabei den in Fig. 5 sche­matisch dargestellten Ruhezustand ein, in den der in vertikaler Richtung verschiebbare Stab 12 sich mit seinen Hohlräumen 13 außerhalb des Wirkstoffbehälters befindet, was durch die Kraft der Feder 14 sichergestellt wird.The closed device 11 is filled with active substance in the toilet bowl and takes the rest shown schematically in Fig. 5, in which the vertically displaceable rod 12 with its cavities 13 is outside the active substance container, which is due to the force of the spring 14 is ensured.

Setzt jetzt der Spülvorgang ein, wird Spülwasser in Richtung des Pfeiles 15 fließend auf den Flügel 16 drücken, der am Gelenk 17 drehbar mit dem Gerät und am Punkt 18 nicht ganz starr mit dem Stab 12 verbunden ist. Der Flügel ist so breit, daß das Spülwas­ser nur zu einem geringen Teil vorbeifließen kann. Zur Verstär­kung der Wirkung ist eine nach innen gebogene Form des Flügels denkbar. Der Wasserdruck drückt den Flügel 16 nach unten, was durch das Gelenk 17 bzw. den Verknüpfungspunkt 18 am Stab 12 zu einer Aufwärtsbewegung desselben führt. Während des gesamten Spülvorgangs wird der Stab gegen die Kraft der Feder 14 so weit nachnoben gedrückt, daß sich seine Hohlräume 13 innerhalb des Wirkstoffbehälters befinden und dort den Wirkstoff aufnehmen.If the rinsing process now begins, rinsing water will flow in the direction of arrow 15 onto the wing 16, which is rotatably connected to the device at the joint 17 and not quite rigidly connected to the rod 12 at point 18. The wing is so wide that only a small part of the rinsing water can flow past. To increase the effect, an inwardly curved shape of the wing is conceivable. The water pressure pushes the wing 16 down, which leads to an upward movement of the bar 12 through the joint 17 or the connection point 18 on the rod 12. During the entire rinsing process, the rod is pressed against the force of the spring 14 until its cavities 13 are inside the active substance container and take up the active substance there.

Ist der Spülvorgang beendet, drückt die Feder 14 den Stab wieder nach unten, wodurch gleichzeitig der Flügel 16 nach oben gedrückt wird und die in Fig. 5 dargestellte Ruhestellung einnimmt.When the rinsing process is finished, the spring 14 presses the rod down again, whereby the wing 16 is pressed upwards and assumes the rest position shown in FIG. 5.

Das während der oberen Stellung in den Hohlräumen 13 gesammelte Produkt des Wirkstoffbehälters kann jetzt am Stab herunterrinnen und in das Toilettenbecken tropfen, weil sich die Hohlräume wie­der außerhalb des Wirkstoffbehälters befinden. Es wird also die Menge Wirkstoff, die sich in den Hohlräumen gesammelt hatte, do­siert in das Toilettenbecken gegeben.The product of the drug container collected in the cavities 13 during the upper position can now run down the rod and drip into the toilet bowl because the cavities are again outside the drug container. The amount of active ingredient that had collected in the cavities is then metered into the toilet bowl.

Mit 19 ist eine Führungshülse schematisch angedeutet, damit der Stab 12 nur in einer bestimmten Richtung verschiebbar ist.

  • Fig. 7 und 8 zeigen das eingebaute erfindungsgemäße Gerät in Form einer technischen Zeichnung, in der die gleichen Bezugszeichen wie bei der ersten Ausführungs­form verwendet werden und aus denen noch weitere Einzelheiten für den Fachmann ersichtlich sind.
With 19 a guide sleeve is indicated schematically so that the rod 12 can only be displaced in a certain direction.
  • 7 and 8 show the built-in device according to the invention in the form of a technical drawing, in which the same reference numerals are used as in the first embodiment and from which further details are apparent to those skilled in the art.
