Definitions

  • the invention relates to a multi-chamber device for dispensing active substance preparations into a toilet bowl with a receptacle for the active substance preparation, which is typically arranged under the edge of the toilet bowl and overflows during flushing.
  • active substance preparations in lumpy or substantially solid form ("toilet blocks") in a cage-like receptacle on the inner edge of the toilet bowl.
  • part of the active ingredient preparation of a toilet block dissolves in the flushing water and is distributed together with the flushing water in the toilet bowl.
  • EP2310582 A1
  • a smaller part of the dissolved active ingredient preparation remains in the residual water in the toilet bowl and also ensures cleaning there.
  • the amount of active ingredient preparation that remains in the toilet bowl after flushing is quite small.
  • a major disadvantage of all these toilet baskets is accordingly that the metering of all possibly different active substance preparations present in the receptacle proceeds essentially simultaneously and during the rinsing process. As a result, active ingredient preparations which should have their effect after the start or at least partially after the end of the rinsing process cannot function optimally.
  • the object of the invention is therefore to provide a simply constructed device for dispensing active substance preparations into a toilet bowl, the active substance preparations being dispensed into a toilet bowl at the optimal time.
  • the device according to the invention for dispensing active substance preparations into a toilet bowl comprises a receptacle to be arranged in the toilet bowl, the receptacle can be attached to the toilet bowl.
  • the receptacle comprises a first chamber and at least a second chamber.
  • the first chamber releases a first active substance preparation into the toilet bowl when flushing water flows over it and the second or further chamber releases a second or further active substance preparation into the toilet bowl when flushing water flows over it.
  • the chambers are designed in such a way that at least the first active substance preparation and the second or further active substance preparation are released into the toilet bowl both at different times from one another and at least one of the active substance preparations with a delay in relation to the flushing process.
  • the further chambers can again contain the first, second or another active substance preparation which are released into the toilet bowl at different times or preferably at the same time as the corresponding preparations from the first or second chamber. However, they can also contain one or more further active substance preparations, which in turn can be released into the toilet bowl either simultaneously with one of the other preparations or at different times.
  • an "active substance preparation” is understood to mean a solid preparation which is dissolved by rinsing water when it is in contact with it and is subsequently used as a solution containing the active substance, ie. H. Mixture of flushing water and active ingredient can be released into the toilet bowl. Such a solution containing the active ingredient can also be created, for example, by the flushing water in the receptacle flowing over a solid toilet cleaning block and then being released into the toilet bowl.
  • the time offset enables the targeted delivery of the same or different active substance preparations into the toilet bowl at different times.
  • a normal flushing process within a normal toilet bowl has two characteristic points in time, namely the start of flushing and the end of flushing. These times define the time windows: before the rinsing process, during the rinsing process, and after the rinsing process.
  • the first and the second active substance preparations are different. Since different active substance preparations can have different functions, it often makes sense for different active substance preparations to be delivered at different times during the rinsing process in order to optimally fulfill these functions. Delivery optimized in this way saves preparation of active ingredients and achieves the best performance.
  • the device according to the invention which does not have an additional, for example electrical, mechanism for the independent release of active substance, can be used at the earliest when the Dispense the active ingredient preparation from the first chamber into the flushing water and thus into the toilet bowl.
  • the rinsing water overflows the first chamber, among other things, and enters the first chamber via an inlet, overflows the first active substance preparation, and flows as an active substance-containing solution enriched with the first active substance preparation via an outlet out towards the toilet bowl.
  • the second preparation of active substance reaches the toilet bowl from the second chamber, but the delivery is delayed.
  • the delivery of the second active substance preparation can begin at least 1 s, preferably at least 2 s after the start of the delivery of the first active substance preparation, and / or it takes, for example, at least 1 s, preferably at least 2 s longer than the delivery of the first active substance preparation.
  • the device according to the invention is designed for toilet bowls with a flushing process in which the flushing water overflows at least one point on the inner wall of the toilet bowl.
  • the device according to the invention is therefore suitable, inter alia, for toilet bowls according to standard EN 997 (2003 + A1: 2006) Class 1.
  • the term "same overflow" in the sense of the invention also presupposes a simultaneous start of overflow.
  • the device preferably comprises a rinsing water distribution element, for example a distribution plate as in EP2310582 is known, which is arranged and configured so that the rinse water distribution element is subjected to rinse water during rinsing and causes a uniform release of the rinse water in all chambers.
  • the time delay is achieved by a time delay device designed as a siphon.
  • the time delay device is arranged in series within the flushing water flow, which can flow through one of the chambers, in order to influence the flow.
  • the siphon defines a trigger threshold level and an abort threshold level for rinsing water with active ingredient-containing solution in the receiving container, via which the rinsing water with active ingredient-containing solution can begin or stop flowing through the siphon.
  • the preferred variants for the time delay device are explained in detail below.
  • At least the second chamber comprises the time delay device designed as a siphon.
  • the second chamber comprises a time delay device designed as a siphon, and the first chamber a further time delay device which has a different time delay than the time delay device of the second chamber.
  • the second chamber comprises a time delay device, while the first chamber has no time delay device.
  • the first preparation of active ingredient from the first chamber is thus dispensed into the toilet bowl immediately after the start of the overflow of the receptacle from the first chamber.
  • the time interval between the start of the overflow of the receiving container and the discharge from the first chamber is significantly shorter than 1 s, preferably shorter than 0.2 s.
  • a chamber in the sense of the invention does not have a time delay device when a defined amount of flushing water can flow out of a chamber essentially as quickly or faster than it flows into the relevant chamber.
  • the outlet opening (s) of the second chamber have a smaller overall cross-section in relation to the first outlet opening (s) of the first chamber.
  • the individual outlet openings of the first chamber have a larger individual diameter than the outlet openings of the second chamber.
  • the second chamber with a time delay device has fewer outlet openings than the other chambers without a time delay device. If necessary, there is only a single outlet opening in the second chamber. As a result of this smaller number, only a smaller flushing water volume can flow away at the same time, so that a time delay compared to the first chamber with more outlet openings is brought about.
  • the time delay device is a siphon. It was found that chambers with smaller volumes fill up with rinsing water very quickly during the rinsing process, and leave little adjustment possibility for setting the time delay for the start of the spout. On the other hand, it was found that a siphon can be designed very flexibly, so that the drain can be delayed a few seconds compared to the start of flushing even in smaller chambers. A siphon is also preferred for chambers with a water collection volume of less than or equal to 50 cm 3 , even more preferably less than or equal to 30 cm 3 . In a preferred variant with a siphon, the siphon comprises a pipe and a cover, the cover being attached to the pipe.
  • the first and the second active substance preparation contain ingredients which are incompatible with one another. When present in a preparation at the same time, these could, for example, enter into undesired chemical reactions with one another or lead to a phase separation. However, they can also be different dyes, the mixing of which in a single phase would lead to a changed, undesired color impression. Examples of ingredients that may be incompatible with one another are bleaches and dyes or fragrances, or proteases and other enzymes. Other examples are well known to those skilled in the art. Due to the staggered delivery, both active substance preparations can at least partially develop their effects independently of one another.
  • the first active substance preparation and the second active substance preparation are compatible with one another, but should have their effect at different times, so that they are kept in different chambers of the device.
  • the first and the second active substance preparation contain different active substances of the same active substance class, but which are chemically different. For example, different surfactants or different enzymes can be used.
  • the first and the second active substance preparation can contain the same active substances in different concentrations.
  • the second active substance preparation comprises at least one active substance which is supposed to have its effect mainly after a rinsing process.
  • An example of such an active ingredient is a water-soluble dye which colors the rinse water, a blue color being preferred. This dye is not rinsed away even after the rinsing process has ended, but remains in sufficient concentration in the toilet sump, ie in the rest of the rinse water remaining in the toilet bowl, to give it a, preferably blue, color.
  • active ingredients which also or mainly have an effect after the rinsing process has ended are fragrances, ingredients which dissolve lime and urine, rinse aid or substances to increase the gloss, Surface treatment agents such as soil repellent agents or agents to combat bad smells, disinfectants or bleaches, foam boosters.
  • one of the active substance preparations comprises an active substance which is supposed to have its effect mainly during a rinsing process.
  • a surfactant for foaming for foaming.
  • the rinsing process is used to form foam by mixing surfactant-enriched rinsing water and air. This surfactant should essentially be released into the rinsing water during the rinsing process in order to avoid excessive release of the surfactant active ingredient.
  • Another example is an active ingredient preparation that is supposed to clean the toilet bowl by chemical-mechanical cleaning. This must be given off during the rinsing process, preferably starting at the beginning of the rinsing process.

  • This is particularly advantageous in a chamber with a time delay device. For example, if the second chamber is one Has time delay device, in particular a siphon, the chamber remains filled with rinse water at a certain level longer. A spherical toilet block therefore has little contact with the flushing water in the lower area and is therefore not unnecessarily dissolved.
  • the receptacle comprises at least one wall that separates the first and the second and possibly further chamber. This ensures that the possibly incompatible active substance preparations located in the at least one first chamber and the at least one second chamber do not come into contact, as a result of which, for example, undesired reactions between the individual active substance preparations or color transfers between the chambers can be avoided.
