Definitions

• the invention relates to a device for dispensing active substances into the flushing water of a toilet bowl or the like.
• a device of the type mentioned at the outset is known from DE 195 20 145 and has a container for a gel-like substance which is permeable to aqueous liquids in the lower region, but is not for the gel-like substance.
• This device is intended to prevent the gel-like substance from dripping between the rinsing processes.
• the so-called "sump effect" is to be excluded by the partial permeability of the lower area, i.e. an uncontrolled release of the active ingredient during the subsequent rinsing process by dissolving the active ingredient should be ruled out due to the partial permeability of the lower area of the container.
• a disadvantage of the known device is the design of the container receiving the active ingredient in such a way that permeability to liquids, but not to the gel-like substance, is to be ensured in the lower region, since considerable expenditure is required in terms of construction and thereby the manufacture of such a device not only becomes complicated, but also expensive. Since such devices are mass-produced items, they should be anything but cost-intensive and complicated sem.
• the invention is therefore based on the object of creating a device of the type mentioned at the outset with which controlled release of active substance, in particular gel-like substances, is achieved with the simplest possible structure of the device and with low manufacturing costs of the device itself.
• the invention provides a device for dispensing active substances into the flushing water of a toilet bowl or the like, which essentially consists of two adjacent chambers, one chamber for receiving a gel-like substance and the other chamber for carrying out the flushing water and for dissolving the gel-like one Substance.
• the two chambers are separated from each other by an essentially vertical partition. At least one opening is formed in the dividing wall in the foot region of the two chambers, through which the gel-like substance can enter the second chamber in a metered manner and can then be dissolved by the flushing water running through the second chamber and released to the toilet bowl.
• a device is provided in the bottom area which serves to define a predetermined water level of rinsing water within the second chamber after the end of a rinsing process and to prevent the second chamber from being completely emptied.
• the gel-like substance is not flushed out of the housing to different extents, depending on the flushing water, but the gel-like substance is fed into the second chamber in uniform doses, where it is activated by the flushing water and released into the toilet bowl. In this way, an overdose of the active ingredient compared to the rinse water is prevented.
• the second chamber serves as an activation chamber for a concentrated gel substance, i.e. the gel-like substance is taken up and dissolved in the flushing water flowing in or through within the second chamber and then dispensed in a diluted manner into the toilet bowl with the aid of a siphon device or the like.
• the second chamber also ensures that the same amount of gel-like substance remains in it after the rinsing process and can be rinsed out again in the already diluted manner during the next rinsing process.
• the device according to the invention further ensures that a permanent outflow and dripping of water mixed with gel is avoided and thus gel traces in the toilet bowl are also excluded.
• FIG. 1 shows a perspective, exploded view of a first embodiment of the device according to the invention
• Figure 2 is a side sectional view of the device of Figure 1, and
• FIG. 3 shows a modified embodiment of the invention
• FIG. 1 shows an exploded perspective view of a preferred first embodiment of the device according to the invention.
• the device has a housing denoted by 1, preferably made of plastic or translucent plastic, within which two chambers 2, 3 which run essentially parallel to one another are defined.
• the chambers 2, 3 lie essentially next to one another and, according to FIGS. 1 and 2, preferably have a part-circular cross section, ie an approximately circular bottom.
• the shape of the housing 1 can be changed as desired, for example can also be rectangular or square, without the function of the invention being impaired.
• a partition 4 is provided between the chambers in the housing 1, which runs essentially vertically and thereby divides the housing 1 into two chambers, for example of the same volume. If necessary, the chambers 2, 3 can also be designed with different widths, which gives them different volumes.
• the first chamber 2 serves to receive a gel-like or gel-like substance as the active substance, while the second chamber 3 is provided in order to read or read the active substance obtained from the chamber 2, to dose it and in a metered amount to that in the Figures not to deliver toilet bowls.
• At least one connection opening 5 is provided in the partition 4, through which the gel-like substance located in the first chamber 2 reaches the second chamber 3 in a metered manner.
• the chamber 3 has a siphon device 8 on its lower side, ie in the area of the base designated 6.
• this siphon device consists of an inner tube 9 and an outer tube 10.
• the outer tube 10 has a larger cross section or diameter than the inner tube 9 and a slightly larger height than the inner tube 9, while the inner tube 9 passes through the bottom 6 of the chamber 3 is done below.
• the outer tube 10 sits on the floor 6 and stands up.
• the outer tube 10 is further provided with a closure 10a, i.e. with a cover, which closes the outer tube 10 upwards relative to the chamber 3.
• a closure 10a i.e. with a cover
• either the outer tube 10 is at its lower end slightly spaced from the bottom 6, in which case the outer tube 10 is held relative to the inner tube 9 by webs 11 indicated in FIG. 2 .
• the outer tube 10 can also stand directly on the base 6, although individual openings are to be provided circumferentially around the outer tube 10 near the base 6 in order to allow the liquid to pass from the chamber 3 into the interior of the outer tube 10 to the inner tube 9.
• the outer tube 10 thus has a pot-shaped shape and largely encloses or covers the inner tube 9.
• the tube 10 provided with the lid 10a thus defines in the vicinity of the base 6 either a circumferential slot or an encircling opening or there are circumferential and preferably mutually spaced openings in the tube wall 10 near the base 6, which are shown in FIG. 2 by the reference symbol 10b are indicated.
• the top of the two chambers 2, 3 is covered by a cover 12 or a similar closure, the cover 12 being able to be provided with openings 13, 14 through which the rinsing water can get into the chambers 2 and / or 3.
• In the area of the cover 12 there are preferably overflow openings 16, 17 to the side of the chambers 2, 3 and preferably at the same height.
• the overflow openings 16, 17 cause rinsing water to flow out of both the chamber 2 and the chamber 3 as soon as the level of the chambers 2, 3 defined by the overflow openings 16, 17 is exceeded by rinsing water.
• the overflow openings 16, 17 thus also serve to meter rinse water in relation to the gel-like substance that is located in the chamber 2.
• a holder 19 is provided, which is used to be able to fix the device on the edge of the toilet bowl.
• the holder 19 is preferably designed such that the gel-like substance-containing chamber 2 is spaced apart from the vertical pool edge, while the chamber 3 receiving the rinsing water comes as close as possible to the approximately vertically running pool wall, whereby a sufficient rinsing effect of the second chamber 3 also Rinsing water is guaranteed.
• connection opening 5 which can also be designed in the form of a slot or can be formed by a plurality of such openings, is located in the lower region of the chamber 2.
• the method of operation of the device according to the invention is as follows:
• the first chamber 2 serves to receive the gel-like active substance substance, which is dispensed into the chamber 3 in a metered manner through the connection opening 5.
• rinsing water remains in the second chamber 3, specifically in the space defined by the bottom 6 and by the bottom 6 on the one hand and by the pipe section 10 on the other.
• Gel-like active substance is able to enter this rinsing water from the chamber 2 via the connection opening 5 and is therefore already dissolved after the rinsing process, ie the rinsing water remaining in the chamber 3 is already enriched with the active substance.
• fresh rinsing water enters the second chamber 3 through the opening 13 and mixes with the rinsing water containing active ingredient there and is rinsed out into the toilet bowl via the siphon 8 consisting of the pipe sections 9, 10, 10a.
• gel-like substance is metered into the rinsing water within the chamber 3 via the connection opening 6 and emerges from the chamber 3 together with the outflowing rinsing water.
• the rinsing water flows out of the chamber 3 until the space above the pipe end of the pipe 10 becomes free.
• the remaining rinse water the level of which is defined by the upper end of the tube 9, is in turn enriched with gel-like substance, which is supplied to a predetermined extent via the connection opening 5.
• the siphon device 8 further ensures that a continuous dripping is prevented when the rinsing water is drawn off via the inner tube 9, since the upper end of the inner tube 9 is lower than the outer tube 10. This removes traces of active substance from such devices after the end of a rinsing process avoided inside the toilet bowl.
• siphon device has the particular advantage that overdosing of the active substance release into the toilet bowl is prevented, while at the same time it is ensured that already dissolved in the second chamber 3 Active ingredient is available at the beginning of a rinsing process and does not have to be withdrawn from the chamber 2 during the rinsing process.
• the metered delivery of active ingredient in the device according to the invention is essentially independent of the design or shape of the chambers 2 and 3.
• the outer tube 10 can be used according to the invention Lids 10a in the chamber 3 are dispensed with, since in this case the remaining water level is ensured by the height of the pipe 9 reaching inwards relative to the chamber 3.
• the cover 12 is preferably pivotably articulated on the housing part 1 by means of a film hinge designated 21.
• Figure 3 shows an embodiment modified from the embodiment of Figures 1 and 2.
• the device shown in FIG. 3 likewise consists of a first chamber 2 and a second chamber 3.
• the two chambers 2, 3 are arranged essentially parallel to one another.
• the chamber 2 serves to receive the gel-like active substance
• the chamber 3 mainly serves to carry out rinsing water and is provided on its bottom 6 with at least one tubular device 9 which projects upwards from the bottom at a predetermined height and for the purpose of a specific discharge of the rinsing water is also extended downwards relative to the floor 6 through the floor 6, as represented by the reference number 9a.
• a discharge of rinsing water from the chamber 3 is thus achieved through the pipe 9 while maintaining a residual rinsing water, the level of which is defined by the upper opening of the pipe 9 in the second chamber 3.
• the chamber 3 is extended downwards relative to the chamber 2, while the chambers 2, 3 in this embodiment define a common upper horizontal plane and are optionally covered by a cover, not shown.
• the partition 4 located between the first and second chambers 2, 3 is provided in the vicinity of the bottom of the first chamber 2 denoted by 2a with at least one opening, a slot or the like which is denoted by 5 and has the same function like the connection opening 6 in the embodiment according to FIGS. 1 and 2.
• the connection opening 6 or each connection opening 6 has a cross section such that a metered supply of gel from the first chamber 2 into the second chamber 3 is ensured.
• the gel chamber 2 is also preferably provided at a distance from the toilet bowl wall, while the second chamber 3 is arranged as close as possible to the toilet bowl wall in order to ensure that the second chamber 3 is flushed thoroughly with flushing water.
• the holder, which holds the device inside the toilet bowl, is also not shown in FIG. 3.
• the rinsing water supplied via the openings 14 remains within the second chamber 3 to a level which is defined by the pipe end 9 and, after the rinsing process has ended, the active ingredient is charged in a metered manner via the connecting opening or connecting openings 6, so that the active ingredient is metered into the rinsing water remaining in the second chamber 3.
• the first chamber 2 receiving the gel-like substance is preferably provided with a filling opening 23 in order to make it possible to refill with active substance.
• the filling opening 23 is preferably located in the upper region of the first chamber 2 and is shown in FIG. 2 in relation to the first embodiment.
• a typical, essentially U-shaped siphon pipe can be provided, which protrudes upwards into the chamber 3 from the floor 6 over a predetermined height in accordance with the embodiments according to FIGS. 1 to 3, while the U-shaped siphon tube section is formed approximately at the height or below the floor 6.
