Definitions
- the invention relates to a cleaning device with a container for detergents, which can be attached in an operating position for cleaning a toilet cistern and a toilet bowl in the cistern and has at least one bottom-side passage opening from which a portion of those in the container during a flushing process , Cleaning agent-containing liquid emerges, the respective flow opening being below the flushing water level when the cistern is full, which can be shut off by a gas bubble.
- Such a cleaning device is known from the generic DE 29 16 274 C2.
- a plurality of passage 'openings in the form of small flow holes provided whose Automated flow holes, said subset in the container liquid flow out with detergent and, on the other hand, the gas bubble captured by parts of the container in the form of an air bubble cannot escape upwards.
- an economical and long-lasting release of detergent to the flushing water flowing through the container is made possible. Because of these advantages, the known cleaning device has proven very useful in practice.
- the object of the invention is to provide, while maintaining the described advantages of the known cleaning device, one which is functionally reliable in operation irrespective of the type of cleaning agent to be used and in particular ensures uniform detergent dispensing.
- a cleaning device with the features of claim 1 solves this problem.
- At least one valve is provided which closes the associated passage opening under the action of the gas bubble when the flushing water rises in the cistern and releases during the flushing process for the metered delivery of the cleaning agent, the free one
- the passage cross-section which can be completely covered by the valve, is enlarged, with the result that blockages are avoided with certainty.
- the respective passage opening is also flush with parts of the container bottom can be trained so that there is no swamping of the cleaning agent.
- the valve mentioned is functionally reliable and can be controlled in a defined manner by the liquid levels and the gas bubble, in particular in the form of an air bubble, so that the functional safety of the entire cleaning device is guaranteed even over a relatively long period of time. In particular, it is possible to make do with only one flow opening, which can be produced inexpensively and whose passage cross section is also dimensioned such that blockages do not occur.
- the valve has a closing part which is arranged between the respective passage opening and the underside of the container and is movably held within an orifice space which is open at the bottom and is surrounded by a container edge in such a way that it is the Includes an air bubble created when the flushing water rises in the cistern.
- the closing part preferably consists of a thin film which is fixed at least at the edge at a point on its outer periphery on the container and which covers or releases the respective passage opening. This represents a particularly cost-effective design of the valve for the cleaning device.
- the film consists of a thin plastic material, so that the film valve formed in this way can be controlled particularly easily by the pressure conditions with regard to the liquid levels and the gas or air bubble and reacts without delay.
- the valve has a closing part which has a receiving part which is open towards the bottom and which serves directly to receive an air bubble which arises in the cistern when the flushing water rises.
- the valve has a closing part which constantly contains the gas bubble.
- the mouth space can be dispensed with, and since the closing part constantly contains the gas or air bubble, the closing part does not have to be "caught" by the closing part either, which overall improves the functional reliability of the cleaning device according to the invention device benefits.
- the container has in its upper region at least one inflow opening ⁇ which, when the container is in the operating position, for filling it with rinsing water when the cistern is full, is located below the rinsing water level.
- the respective inflow opening is part of a hollow chamber of the container which has at least one outflow opening which opens into the receiving chamber for the cleaning agent which is at least partially separated within the container.
- the receiving chamber for the cleaning agent is separated from a dispensing chamber via a partition which is connected to the environment via the respective passage opening.
- This dispensing chamber serves to hold and store the partial quantity of the liquid containing detergent in the container, which liquid can first be called up into the cistern via the respective flow opening for a flushing process.
- two hollow chambers are provided which release between them an insertion channel into which a hook part engages to fix the container in its intended operating position and which engages over the upper edge of the cistern by means of its hook.
- the hook part preferably engages with a rod-like extension in the insertion channel, which has a clamping part at its end facing away from the hook for the defined fixing of the hook part in the insertion channel.
- the container can be moved by hand with respect to the fixed hook part and its operating position can be freely adjusted regardless of the type of cistern.
- the container In its upper region, the container preferably has a marking section which, in the operating position of the container, is flush with the flushing water level when the cistern is full and, as a marking aid, makes it easier for the operator to attach the container in its operating position.
- the container has a lid with an exchange opening for the cleaning agent, in particular in the form of a cleaning block, which is partially covered by a movable tab of this cover.
- the cleaning device can be provided with a corresponding label directly on the market, without the need for additional packaging, which benefits the environment.
- a used cleaning block can then be exchanged for a new one via the movable tab, even if the cleaning device is fixed in the cistern.
- Fig.l in a perspective view the rear view of the container of the cleaning device with the lid open;
- the cleaning device has a container designated by 10 for. Detergent 12 on.
- the container 10 for cleaning a toilet cistern 14 shown in principle and a toilet bowl (not shown) can be attached in this cistern 14 in an operating position.
- the container 10 has a circular bottom-side passage opening 16, from which a subset 18 of the liquid containing cleaning agent 12 contained in the container 10 emerges during a rinsing process, as is shown in principle in FIG. As shown in FIG. 4, which shows the cistern 14 filled, this passage opening 16 is then below the flushing water level 20.
- the circular flow opening 16 is surrounded by a container edge 22 which is rectangular and which delimits an opening space 24 which is open at the bottom.
- This mouth space 24, which is open towards the bottom and which forms a kind of diving bell, serves to hold an air bubble 26 which arises when the washing water rises in the washing water tank 14 and which is shown in principle in FIGS. 4 and 6 and 7.
- a valve designated as a whole is provided, which, under the action of the air bubble 26 mentioned, closes the associated passage opening 16 when the flushing water rises in the cistern 14 (see FIGS. 4, 6 and 7) and during the flushing process ( 5) for the metered delivery of the cleaning agent 12.
- the valve 28 has a closing part which is arranged between the respective passage opening 16 and the underside 30 of the container 10 and is movably held within the orifice chamber 24. 4 to 7 the possible direction of movement is indicated by a dash-dotted line.
- the direction of movement of the closing part thus extends essentially to a direction parallel to the longitudinal axis of the container Axis.
- the closing part consists of a thin film 32, which, as shown in particular in FIG. 2, has a rectangular shape and is fixed along its outer edge at the point facing the front wall of the container via an adhesive or weld seam 34 .
- the film 32 which preferably consists of a thin, transparent plastic material, can then open or shut off the passage opening 16.
- a closing plate (not shown) could also be used, which has transverse openings and is guided along the edge within the mouth space 24 via the boundary or container edge 22 so as to be longitudinally movable. Because of the light film material, however, very quick opening or closing operations for the passage opening 16 are possible.
- the valve 28 can also be designed such that it covers a plurality of passage openings (not shown). A plurality of valves located one behind the other or opposite one another can also control the passage openings (not shown) assigned to them.
- the height of the orifice chamber 24 is dimensioned such that in any case the air bubble 26 can be securely received and can lie against the film valve while closing it. As shown in FIGS. 4 to 7 in particular, the mouth space 24 is bounded at the top by an intermediate wall 36, in which the passage opening 16 extends through the intermediate wall 36 and is arranged essentially centrally.
- the container 10 has in its upper area two mutually opposite inflow openings 38 at the rear which, according to the representations in FIGS. 4 and 7, in the operating position of the container 10 for filling it with rinsing water when the container is full Cistern 14 are below the flushing water level 20.
- the respective inflow opening 38 is part of a hollow chamber 40 of the container 10, which is separated towards the interior 42 of the container via a rear intermediate wall 44 which is connected to the interior 42 of the However, container 10 is connected via an oval discharge opening 46 (FIGS. 4 to 7).
- the respective outflow opening 46 opens into a receiving chamber 48 for the cleaning agent 12, which is at least partially separated inside the container 10.
- the two inflow openings 38 are formed by channel-like incisions in the boundary walls of the hollow chamber 40 assigned to them, which in the rest are downward towards (Fig.l) are each delimited by a boundary wall 50 which extends transversely to the longitudinal axis of the container somewhat below the center of the container 10.
- Each of the two boundary walls 50 runs essentially vertically downward against a lateral boundary wall 52, each of which laterally delimits a rectangular recess 54 on the rear of the container 10.
- the two hollow chambers 40 delimit an insertion channel 58 with a rectangular cross-section, in which, in order to fix the container 10 in its operating position shown in FIGS 3 engages hook part 60 which overlaps the upper edge (not shown) of the cistern 14 by means of its multi-part hook 62.
- the hook part 60 has a rod-like extension 64 which, at its end remote from the hook 62 (not shown in FIG. 1), has an essentially oval clamping part 66 which, compressed by its projection, engages in the insertion channel 58 and there the hook part 60 specifies.
- both the container 10 and the hook part 60 are preferably formed from a plastic material, the clamping part 66 can be moved by hand within the insertion channel 58 with little effort and thus mount the container 10 in its operating position. As a rule, only a single adjustment process will be necessary for this. So that the container 10 can be brought exactly into its operating position within the cistern 14, this has in its in the upper area on a bead-like protruding marking section 68 which, apart from the rear side of the container 10, surrounds it. When the cistern 14 is filled, the container 10 is then lowered into the rinsing water until the rinsing water level 20 is flush with the underside of the marking section 68 (see FIGS. 4 and 7).
- the already mentioned receiving chamber 48 for the block-type cleaning agent 12 is separated via a partition wall 70 running vertically within the container 10 from a discharge chamber 72 (see FIGS. 4 to 7), which is connected to the orifice chamber 24 via the passage opening 16 .
- the discharge chamber 72 which is essentially rectangular in cross section, opens out from the partition 70 in question, with its other free end facing away from the passage opening 16, into a discharge space 74 which extends transversely above the cleaning block 12 and with the receiving chamber 48 over the entire area lower connection cross section is in fluid communication.
- the top of the container 10 can be closed with a lid 76, which is shown opened in FIG. 1 and which can be connected to the container 10 by a snap connection to close it.
- This cover 76 has an exchange opening 78 for the cleaning agent 12, which is partially covered by a movable tab 80 of this cover 76. If the cleaning block within the container 10 is used up by rinsing, the tab 80 is folded up with the cover 76 in place and a new cleaning block is inserted into the receiving chamber 48 and then the tab 80 is brought back again so that it is flush with the top of the cover 76.
- the container 10 is completely flooded with rinsing water and the rinsing water level 20 has reached its uppermost position.
- the hook part 60 is set on the container 10 in such a way that the water surface can rise to the lower edge of the strikingly attached bead in the form of the marking section 68.
- the cleaning device which is also referred to as a water box automatic
- an air bubble forms in the mouth space 24, which forms a small chamber for the air bubble 26.
- This air bubble 26 presses against the film 32 with full buoyancy force and thus closes the circular passage opening 16.
- the water level 20 in the container 1L of the cleaning device is adapted to that of the cistern 14, there are two different liquid systems, namely the normal rinsing water in the cistern 14 itself and secondly the water enriched with cleaning agent in the automatic water cistern. If the flushing then takes place, which is shown in principle in FIG. 5, the flushing water level 20 drops below the underside of the container 30. Here, the container 10 remains closed via the film valve 28 and at its liquid level until the liquid level 20 has reached the lower edge 30 of the cleaning device.
- the hydrostatic pressure of the water enriched with cleaning agent 12 inside the container 10 is so great that the film 32 together with the air bubble 26 is pressed downward and all the liquid present in the dispensing chamber 72 up to the height of the partition wall 70 the receiving chamber 48 flows into the cistern 14. Due to the dimensioning of the passage opening 16, this process is ended shortly before the water tank valve closes.
- the cleaning agent 12 is dissolved particularly well and quickly in the rinsing water and, as shown in FIG. 4, there is again a subset 18 of liquid to be dispensed in the dispensing space 72 when the rinsing water tank 14 is completely filled With a new rinsing process, the cycle shown starts again from the beginning.
- no flushing water is to be supplied from the top of the container 10, for example via the lid opening 78.
- FIGS. 8 and 9 Two further embodiments of the cleaning device according to FIGS. 8 and 9 are explained in more detail below.
- the same parts are reproduced with the same reference numerals, but increased by 100 as in the first embodiment.
- the statements made for this apply accordingly, so that the following embodiments are only explained insofar as they differ significantly from the previous embodiment.
- the respective flow opening 116 and 216 lies in one plane with the respective underside 130 or 230 of the respective container 110, 210.
- a slide valve 128 is used to close the flow opening 116 (see FIG. 8), which in turn essentially forms a flat plate and has a receiving part 190 which is open towards the bottom and which has the shape of a diving bell, in order to directly hold the flushing water in the cistern 114 the resulting air bubble 126.
- the free end of the film 132 facing away from the receiving part 190 can be firmly connected to the underside 130 of the container 110 via a type of joint in the form of an adhesive or welded seam 134.
- the receiving part 190 can be in one piece part of the film valve 128, but can also be subsequently placed on the film 132.
- the foil valve 228 is also connected in an articulated manner to the underside 230 of the container 210 via a weld or adhesive seam 234 with the flat film piece 232.
- the film 232 On its underside and the passage opening 216, the film 232 has a closed trough in which an air bubble 226 is permanently enclosed. Instead of the air bubble 226 it can also another buoyant gas bubble may be included for the film 232.
- the aforementioned film valves 128 and 228 are also formed from a thin plastic material. Guided via corresponding edge guides (not shown), both the receiving part 190 and the film trough, as shown in FIG.
- the respective film material for the mentioned film valves is dimensioned so thin that they can rest on the edge of the passage opening and therefore seal the respective passage opening in a sealing manner.
- a sealing seat depending on the pressure conditions prevailing at the passage opening, the film material is sucked somewhat into the passage opening.
- Conventional valve seats such as are required in known valves, for example in the field of hydraulics, can therefore be dispensed with.
