Definitions
- the invention relates to a device for dispensing active ingredient preparation into a toilet bowl with a receptacle which is to be arranged in the toilet bowl in the meantime and overflowed during flushing.
- a generic device is from the US4168551 known.
- the device shown there has a chamber with the toilet block and, downstream, another chamber.
- the chamber with the toilet block is separated from the further chamber by a partition wall with at least one opening.
- Disadvantages of this known device are the multi-part construction and the use of a bar grate-like wall for holding the partition wall, which thus lead to an expensive construction.
- the GB2194258A shows a toilet cleaning device with a first and a second chamber.
- the first chamber stores a block of toilet cleaning material and has a perforated upper part and means for dispensing liquid from its lower part.
- the second chamber has a perforated upper part and an opening in its lower part so that when each chamber is filled with liquid, the second chamber will not empty faster than the first chamber.
- the GB2339210A discloses a toilet cleaning device having first and second cup-like parts the open ends of which are secured together to define a chamber for a composition.
- the chamber has relatively large inlet means for entry, and relatively small outlet means for exit, of water.
- the WO2010037997A1 Figure 13 shows a toilet dispenser having a spray device which spray jets of a composition directed across the interior volume of the toilet bowl and towards an opposite side wall of the toilet dispenser.
- the object of the invention is therefore to improve a device of the generic type in such a way that it ensures a release of the active ingredient preparation into the toilet bowl that is as constant as possible over time with the least possible structural effort.
- the receptacle is held by the holder on the toilet bowl so that, in the position of use, the tub lies below the holder. In the division of use, the toilet block is held above the demolition threshold level by means of the support plate.
- the bracket is preferably a bracket-shaped hanging bracket, for example.
- the device according to the invention has the advantages that dripping of dissolved active substance into the toilet bowl is reduced or even completely prevented.
- the flushing water can wash over the toilet block and flow freely to the bottom of the tub and with a time delay through the outlet into the toilet bowl. Once the siphon has started flowing, the tub will essentially flow. Thus, after the rinsing process, the rinsing water flows out of the receiving container without any appreciable water residues remaining.
- the support plate is preferably designed in such a way that the toilet block is held on the side of the support surface.
- the support surface is the surface of the upper side of the support plate, divided in use.
- the support plate is designed in such a way that flushing water can run over and drain on the toilet block at the same time, so that the amount of water that remains on the toilet block is minimized.
- the toilet block is kept essentially dry between two successive flushes. This is achieved by minimizing the contact area between the support plate and the toilet block.
- the support plate in order to ensure that the toilet block retains its position within the receptacle even after it has been used up, the support plate must have a minimum dimension between the side walls of the receptacle; this is described in more detail below.
- the siphon comprises a siphon cover which is in one piece. It is further preferred that the support plate and the siphon cover are in one piece. In this way, a particularly cost-effective design results, which is also easy to assemble in its overall arrangement.
- the siphon comprises an outlet pipe and a siphon cover.
- the siphon cover includes an outer tube that has a larger diameter than the outlet pipe.
- the outer tube is closed at one end by the support plate.
- the siphon cover is arranged at least partially around the outlet pipe, so that an annular gap-shaped flow channel section is formed in the area between the outlet pipe and the outer pipe. Further downstream, the outlet pipe itself forms the flow channel.
- the flow channel is also limited by the side of the support plate opposite the support surface.
- the toilet block Due to the one-piece design of the support plate with the siphon cover, the toilet block is supported longer during use. This ensures that the active ingredient preparation is released into the toilet bowl constantly over a longer period of time.
- the siphon cover, and thus at the same time the support plate, are attached to the device in a simple manufacturing step.
- a tube within the meaning of the invention is a segment of an elongated hollow body and can have a circular or other cross-section, e.g. rectangular or oval.
- Cross-section is understood to mean vertical cross-section (vertical cross-sectional area).
- the receptacle comprises support means which are designed in such a way that, together with the support plate, the toilet block is held in position, ie above the demolition threshold level.
- the support means are preferably designed in one piece with the receiving container.
- the support means preferably each have an area (the support area) of less than 5 mm 2 , preferably less than or equal to 3 mm 2 .
- the small area minimizes contact with the toilet block and thus also the volume of residual water that remains on the toilet block.
- the number of support means is preferably a maximum of 10, further preferably a maximum of 6, even more preferably a maximum of 4.
- the small number of support points minimizes contact with the toilet block and the volume of residual water that remains adhering to the toilet block .
- the bearing surface is larger than the outer cross-sectional area of the outer pipe of the siphon cover, preferably 1.5 times larger, more preferably 2 times larger.
- the bearing area is greater than pi * (d 2 ) / 4, where d is the outer diameter of the outer pipe of the siphon cover.
- the contact area is preferably smaller than half, preferably smaller than 1 ⁇ 4 of the maximum area in this plane.
- the maximum area is the internal cross-sectional area of the receptacle. It is also necessary that the supporting surface is kept sufficiently small so that the water flow dynamics within the receptacle are maintained.
- the siphon should start draining the water as soon as the trigger level is reached, especially if the toilet block also includes an active ingredient preparation with a cleaning function. It has been found that a very large bearing surface, even if perforated or otherwise riddled with holes is, the flow inside the receptacle is delayed for too long and leads to dripping or residual water in the tub.
- the device is elongated and conforms to the rim of the toilet bowl.
- a front wall which is arranged in the direction of the inside of the toilet bowl
- a rear wall which is arranged in the direction of the toilet bowl wall
- Spacers are preferably provided on the outside of the rear wall so that flushing water does not remain between the rear wall and the toilet bowl wall due to capillary action. The spacers are important to prevent marks and stains on the toilet bowl wall.
- the support plate for the toilet block extends at least 80%, more preferably at least 90%, between the front and rear walls. This means that the toilet block is held on the support plate even after it is halfway worn.
- these can be two parts connected together (e.g. glued together or coextruded), or two separate parts that are e.g. packed together in a water-soluble PVA film before use.
- one part preferably has a cleaning effect and another part has a color effect.
- additional active ingredient functions such as. B. bleaching, anti-limescale, hygiene function possible.
- this part has a color that is the same color as the receptacle. This color is not colorless or white.
- the other part, which does not have a color effect has a different color, preferably white. In this way, the consumer can at the same time identify the color to be dispensed in the toilet bowl and also that various active ingredient preparations are present in the device.
- An example of this is a blue receptacle in which one toilet block is part blue and the other part white.
- the support plate is separated from the front and rear walls of the receptacle by a maximum distance of 3 mm. This applies in particular to toilet blocks which, when in use, are higher than they are deep. Due to the small distance between the front and rear walls, these are less eroded by the rinsing water and can therefore be kept in the position of use for longer.
- the bearing surface is a closed surface. This ensures that a minimum of residual water and no residual water remain in the receptacle.
- tub bottom has a low point and the siphon is arranged at the lowest point of the tub bottom.
- the inlet opening of the siphon in which the flushing water can flow from the receptacle into the siphon, is up to a maximum of 10 mm, more preferably up to a maximum of 5 mm, above the tub bottom.
- the level of the inlet opening is defined, for example, by the distance from the siphon cover to the tub bottom.
- the siphon cover can also have a tooth-like lower edge, for example. In this case, the distance from the upper tooth edge to the tank bottom must be taken into account. With this configuration, the rinsing water flows almost completely out of the tub due to the capillary effect. This is particularly advantageous in the case where the siphon is arranged at the lowest point of the tub bottom.
- the toilet block is at least in two parts.
- the parts of the toilet block are separate. In the position of use, the boundary between the two parts is on the support plate. Both parts are thus supported by the platen. This is particularly preferred when both parts of the toilet block fulfill different functions, e.g. a cleaning part containing a cleaning composition and a water coloring part containing a dye composition.
- FIG Fig. 1-3 A device 1 according to the invention is shown in FIG Fig. 1-3 shown.
- the device 1 comprises a receptacle 3 which can be fastened to the edge of the toilet bowl with a bracket-shaped holder 10; the holder can also be a different one.
- the receptacle 3 comprises at least one inlet 6 and one outlet 7 for flushing water and is flow-connected to the toilet bowl via the outlet 7, a siphon 8 being arranged upstream of the outlet 7.
- the siphon 8 defines a trigger threshold level 17 and a termination threshold level 18 for flushing water in the interior of the receptacle 3 are.
- the trigger threshold level 17 determines the beginning of the drainage of rinse water through the siphon 8 from the interior of the receptacle 3, while the termination threshold level 18 determines the end of the drainage of rinse water from the receptacle 3.
- the trigger threshold level 17 and the termination threshold level 18 define a desired, regulated drainage of rinsing water from the receiving container 3.
- the receptacle 3 forms, in its lower area in the position of use, a tub 4 with a tub bottom 5 on which the siphon 8 is arranged.
- the receptacle 3 receives the toilet block 2 with the active ingredient preparation 16, see Fig. 3 .
- the toilet block 2 can be flowed over by the flushing water, which can flow into the receptacle through the inlet 6.
- the toilet block 2 is held above the tub floor 5 and, according to the invention, above the demolition threshold level 18 by the support plate 9 and support means 11. If the toilet block 2 is in two parts, it is preferred that the boundary 2.1 between the parts lies on the support plate.
- Fig. 1-3 show that the support plate 9 is part of the siphon 8, and in the present case is integrally formed on the siphon cover and thus delimits the flow channel 19.
- the support plate 9 has a support surface 9.1 which is larger than the cross-sectional area of the outer pipe 8.1 of the siphon cover.
