Definitions

  • the present invention relates to a method for cleaning and/or freshening a toilet bowl, by flushing the toilet bowl with flushing water and adding a cleaning agent to the flushing water from at least one container. Such a method is already widely known.
  • a container or reservoir in which is held a solid or liquid cleaning agent and which is suspended on the inside of the toilet bowl.
  • the container or reservoir is embodied here such that the water can coxae into contact with the cleaning agent during a flushing and can carry it into the toilet bowl.
  • a system already long known makes use of a solid block of a water-soluble cleaning agent which is arranged in a holder having walls hich consist of a very open bar grid. A part of the cleaning block is dissolved and entrained by the flushing water lowing by.
  • Another system applied on a large scale makes use of a container which is filled with a liquid cleaning agent and which is arranged on a vessel or housing with open sides» Received in the vessel is a sponge body connected to the container with cleaning agent by means of a tube. Cleaning agent is drawn by capillary action out of the container into the sponge from which it is then entrained during a flushing by the flushing water flowing past.
  • the known systems have the drawback that the cleaning agent is entrained by the flushing water immediately from the start of the flushing, and thus disappears directly into the sewer. Because the cleaning agent is immediately flushed away, and is therefore only briefly active, it has to be highly concentrated. This is disadvantageous however in respect of the environment, while the costs moreover become relatively high as a result.
  • the dosage of the cleaning agent is uneven, particularly in systems based on liquid cleaning agent, because it depends on the degree of saturation of the sponge body, and therefore on the time between successive flushes. If the toilet is not flushed for too long a time, the sponge body will become oversaturated and the cleaning agent will begin to leak away. Finally, the known systems have the drawback that the user cannot see whether they are active.
  • the invention therefore has for its object to provide an improved method for cleaning and/or freshening a toilet bowl, wherein the above stated drawbacks do not. occur.
  • the invention has for its object to provide a device with which this method can be applied.
  • Th 'method for cleaning and/or freshening a toilet bowl according to the invention is characterized in that the cleaning agent is added to the flushing water substantially at the end of the flushing. In this manner the cleaning agent is taken up into that part of the flushing water which will be left in the toilet bowl after flushing, whereby it has a prolonged effect.
  • a simple manner of achieving this consists of the at least one container being closed in a rest position and being opened substantially at the end of the flush.
  • a dose of cleaning agent can advantageously be transferred, before the flushing, from the at least one container to at least one dosing element, and during flushing the at least one dosing element is brought into contact with the flushing water. This can be achieved with simple means when the at least one dosing element is moved by the flushing water from a filling position, in which it is in contact with the at least one container, to a delivery position in which it is in contact with the flushing water.
  • the invention also provides a device for .cleaning and/or freshening a toilet bowl which is suitable for performing the above described method.
  • a device for .cleaning and/or freshening a toilet bowl which is suitable for performing the above described method.
  • Such a device comprises according to the invention at least one container for a cleaning agent and means for measured delivery of the cleaning agent from the at least one container during flushing of the toilet bowl.
  • the delivery means can be operated by flushing water flowing along the device.
  • the delivery means can for instance comprise for this purpose at least one dosing element which can be operated by the flushing water and which is movable between a filling position, in Which it is connected to the at least one container, and a delivery position in which it is connected to the flushing water.
  • a dosing element which does not move in the container, but which can only be connected thereto, prevents the content of the container influencing the dosage.
  • a dosing element that is simple to operate comprises in this case a float which is received in a space through which the flushing water flows. Because the dosing element is here situated outside the container, the float does not have to overcome any liquid pressure in the container as it moves upward, while during the return movement downward a possible underpressure in the container has no influence either.
  • the at least one dosing element preferably has at least one dosing chamber of precisely' determined dimensions.
  • a side of the at least one dosing chamber open toward the container advantageously has at least one filling opening of relatively large cross-section and at least one venting opening of relatively small cross- section. In this manner is ensured that the dosing chamber can be fully illed with cleaning agent and that no air is enclosed therein.
  • the side of the at least one dosing chamber open toward the container advantageously is preferably located higher than a side thereof open toward the flushing water.
  • the at least one dosing element has a plurality of dosing chambers, which are arranged distributed in the direction of movement of the dosing element such that, when one of the dosing chambers occupies the filling position, another dosing chamber is situated in the delivery position, it is possible to ensure that at the end of r or even after, a flush a further small amount of cleaning agent is released each time from one of the dosing chambers, thereby generating a fresh odour.
  • the device preferably has a plurality of containers which are connected to a common dosing element / whereby the number of components of the device remains limited.
  • the common dosing element can herein then have a plurality of dosing chambers formed at the same height in its direction of movement.
  • the at least one dosing element is received in an intermediate container which is closed on the underside and which is connected to the at least one container.
  • the closed nature of the intermediate container prevents cleaning agent unintentionally escaping from the container due to siphoning when the device is not in use.
  • a dosing system which is simple and precise in all conditions is herein obtained when the device is provided with a tube part which is placed between the container and the intermediate container and which protrudes over a determined length from the top side into the intermediate container, and thus defines a level edge.
  • the device is preferably provided with at least one liquid retaining edge extending downward around the dosing element in the- inter ediate container.
  • the device further has at least one deodorant tube connecting the intermediate container to the ambient air, the fresh odour of the cleaning agent can be spread even when the toilet is not flushed.
  • This variant of the device preferably also has a plurality of containers, each connected to its own dosing element, whereby different cleaning agents and/or air fresheners can be dosed.
  • the device preferably has means for feeding air to the at least one container during delivery of the cleaning agent.
  • a structurally simple embodiment is obtained when the air feed means are received in the delivery means for the cleaning agent, are for instance integrated into the at least one dosing chamber.
  • the space through which the flushing water flows, can be defined in simple manner by a housing for fixing in the toilet bowl which has at least one inlet opening and at least one outlet opening.
  • the at least one outlet opening is herein considerably smaller than the at least one inlet opening, whereby the flushing water with the cleaning agent dosed therein flows with a delay out of the housing into the toilet bowl.
  • the retaining means can herein take the form of a grid which defines a large number of small outlet openings. A large surface area is thus formed on which the retained cleaning agent can evaporate.

  • the delivery means 3 comprise a dosing element 4 which is movable between a filling position, in which it is in communication with container 2, and a delivery position in which it is in communication with the flushing water.
  • Dosing element 4 comprises for this purpose a float 5 (fig. 3) which is received in a space 6 through which the flushing water flows.
  • This space 6 is defined in the shown embodiment by a housing 7 which is almost fully open on the top side 8 and has a relatively small outlet opening 10 on the underside 9.
  • the top side 8 of housing 7 is herein covered by a carrying element 11 having a number of inlet openings 12A (fig. 2) , while the part of housing 7 not covered by carrying element 11 is provided with upright edges 13 between which inlet openings 12B are also defined.
  • the carrying element 11 is provided with a standing, peripheral collar 14 in which the container 2 can be received with a protruding outlet opening 15.

  • the standing collar 14 open to the top is connected to a part 19 which is closed on all sides and which runs out into an opening 31 in a standing guide tube 20 in which dosing element 4 is slidably arranged.
  • the standing collar 14 with the closed part 19 connecting thereto thus forms a connecting channel 21 between container 2 and dosing element 4.
  • an opening 30 through which a slide of the injection mould can be placed during injection moulding of carrying element 11 in order to form the closed part 19 of connecting channel 25 and the opening 31 in guide tube 20.

  • dosing element 4 comprises a float 5 and an elongate part ' 22 standing thereon which is received in guide tube 20 of carrying element 11.
  • this elongate part 22 is formed a dosing chamber 23 which is open to two sides in order to be able to receive cleaning agent from connecting channel 21 in the filling situation (fig. 4) and, after displacement to the delivery position (fig. 6), to be able to deliver this cleaning agent over an upper edge 33 of guide tube 20 to the housing 7 filled with flushing water.
  • Dosing chamber 23 has a bottom 24 and an upper wall 25 which enclose a non-right angle ⁇ with the longitudinal axis of elongate part 22 such that the side 25 of dosing chamber 23 that is open to container 2 lies higher during use than the side 26 which runs out during use into the space 6 in which the flushing water is situated.
  • opening 31 and upper edge 33 of guide tube 20 The chosen distance between opening 31 and upper edge 33 of guide tube 20 is large here such that the side 25 of dosing chamber 23 open toward container 2 is completely covered by guide tube 20 when the opposite open side 26 protrudes above edge 33 in the delivery position, while this open side 26 is wholly covered when the first open side 25 comes into register with opening 31. This prevents the container 2 ever coming into direct contact with the ambient air, whereby a siphoning action could possibly occur, and cleaning agent could flow in uncontrolled manner out of container 2 to housing 7.. So as to further optimize filling of dosing chamber 23, this latter is provided with a relatively large filling opening 27 in the middle of two relatively small venting openings 28 on either side thereof (fig. 7).
  • Dosing chamber 23 is divided for this purpose by longitudinal walls 29 into three segments which are mutually connected on the side remote from container 2 because walls 29 do not extend along the full length of dosing chamber 23.

  • ⁇ means are present for feeding air to container 2.
  • these air feeding means are integrated into dosing element 4 and are formed by dosing chamber 23.
  • dosing chamber 23 When the cleaning agent runs out of dosing chamber 23 in the delivery position, air flows into this latter which, after dosing chamber 23 has returned to the filling position, flows in the above described manner via connecting channel 21 into container 2.

  • at least the top side of dosing element 4 can have a different colour so as to make it even more clearly visible.
  • hook 36 is formed integrally with carrying element 11 by injection- moulding. So as to be able to make use herein of a relatively flat and compact mould, hook 36 is injection- moulded in the plane of carrying element 11 (fig. 8) and, prior to assembly of device 1, is bent through 90 * to a position transversely of carrying element 11. A film hinge 37 is formed for this purpose close to the base of hook 36. Hook 36 is fixed in its bent position by effecting a snap connection between a protrusion 38 arranged on hook 36 and a hooking nose 39.
  • This hooking nose 39 is also injection-moulded in flat state and bent round, for which purpose a second film hinge 40 is formed.

  • the mixture of flushing water and cleaning agent finally flows out of housing 7 via opening 10 on the underside 9.
  • the moment at which the cleaning agent flows into toilet bowl B can be set.
  • outlet opening 10 is very small, the cleaning agent reaches toilet bowl B only at the end of, or even after, the flushing, while with a larger outlet opening 10 cleaning agent can already flow out of device 2 during flushing.
  • a constant dosage of cleaning liquid can thus be introduced in precisely controlled manner into toilet bowl B at each flushing.
  • the dosing element 104 is provided with two dosing chambers 123U and 123L arranged distributed in the direction of movement thereof.
  • the distance between dosing chambers 123L, 123U is herein chosen such that when the upper (main) dosing chamber 123U occupies the filling position, and is in communication with container 102, the lower (auxiliary) dosing chamber 123L is situated in the housing 107 through which the flushing water flows (fig. 9) , while the upper dosing chamber 123U comes out above the upper edge 133 of guide tube 120 when the lower dosing chamber 123L is in communication with container 102.
  • auxiliary dosing chamber 123L is filled with cleaning agent when the main dosing chamber 123U delivers its dosage to housing 107.
  • the auxiliary dosing chamber 123L empties into space 107, in which the cleaning agent is left so that a fresh odour will linger in the toilet bowl for some considerable time.
  • This principle can also be applied in combination with two containers 202 (fig. 10), whereby different cleaning agents or a cleaning agent and an air freshener can be dosed.
  • the containers 202 can herein debouch via respective connecting channels 121 into a joint dosing element 204 (fig. 11). It is thereby possible to suffice with a single float 205 and a single guide tube 220. The number of separate components thus remains limited, whereby the costs of manufacturing and assembling the device 201 remain low.

  • the dosing element 304 is received in an intermediate container 344 which has a closed bottom 345 and side wall 346. There is hereby no danger of cleaning agent leaking out of the container to the flushing water housing 307, as in the foregoing embodiments.
  • Dosing chamber 323 is here annular and is defined by a narrowed part of the cylindrical dosing element 304 in combination with guide tube 320. Dosing chamber 323 is situated in the rest and filling position in intermediate container 344 which is in communication with container 302 at the top via a tube part or connecting channel 321, and thus remains filled with cleaning agent.
  • the intermediate container 344 communicates via an opening 347 in its upper wall 348 with a deodorant tube 349 which debouches in the ambient air and thus continuously disseminates the fresh odour of the cleaning agent.
  • This deodorant tube 349 also serves to vent the intermediate space 344, thereby preventing the creation of an underpressure during delivery of cleaning agent.
  • Formed around guide tube 320 is a downward extending edge 350 which serves during the return stroke to retain flushing water entrained by dosing chamber 323. This is therefore prevented from mixing with the cleaning agent in the intermediate container 344. At a subsequent dosing movement of dosing element 304 this water will then be entrained once again.
  • the space between guide tube 320 and the liquid retaining edge 350 is likewise in communication with deodorant tube 349 and is vented thereby.
  • the lower edge 351 of connecting channel 321 de ines the level of the cleaning agent in intermediate container 344. As long as the liquid level is above this edge 351, container 302 is not vented and an underpressure is created therein, thereby preventing the flow of more cleaning agent to the intermediate container 344.
  • the level in the intermediate container 344 drops below edge 351 due to the repeated delivery of a dosage, air will flow out of intermediate container 344 through connecting channel 321, whereby container 302 is vented and cleaning agent can once again flow to intermediate container 344. Leakage of cleaning agent out of container 302 is thus made impossible.
  • this element is ' provided with a protruding edge 352 which comes to rest sealingly on the upper edge 333 of guide tube 320.
  • the length of guide tube 320 is otherwise also chosen such that via dosing chamber 323 an open 1 connection can never be formed between container 302 and the ambient air (fig. 15, 16) .
  • Another embodiment of the variant with intermediate container 444 (fig. 18) is distinguished in that it is completely closed. Instead of the deodorant tube 349, whereby the intermediate container is in constant communication with the ambient air and there is therefore the danger of drying-up, a choice has been made here to retain some of the dosed cleaning agent in the flushing water housing 407 and to allow it to evaporate gradually there, whereby a fresh small is also disseminated for a long period.
  • the single outlet opening 10 is replaced for this purpose by grid 452 in which a large number of small outlet openings 410 are defined (fig.
  • This variant can be applied with both a single container 402 and a double container 502.
  • They are both further provided with a respective housing 407 and 507 with a respective defor able wall part 453 and 553 which adapts to the shape of the toilet bowl, whereby flushing water cannot escape between the bowl and the respective devices 401 and 501.
  • the container and the carrying element could thus be formed as one unit, wherein the container could then have a filling opening for topping up thereof.
  • a fixing method other than the shown hook could aiso be envisaged.
  • the number of containers and dosing elements can be adjusted, as can the form thereof.
  • the dosing element could also be operated in a manner other than by a float, for instance by a blade wheel which is set into motion by the flushing water flowing past.
  • a simple valve operated by the flushing water could also be arranged in the container instead of an intermediate dosing chamber.
  • the principle of inj ction-moulding the fastening hook in the main plane of the device and the bending round thereof prior to use can also be applied in other, for instance conventional, cleaning devices.
