Definitions

  • the present invention relates to a toilet freshener with electromechanically effected release of adjustable amounts of preparations in or on a toilet bowl.
  • Dispensing of cleaning and fragrancing compositions in the toilet area is currently performed primarily by “toilet fresheners”. These are single- or multi-chamber containers which are hung in the toilet bowl in such a way that an active substance is released from the toilet freshener into the toilet bowl during the flushing process of flushing the toilet bowl with water.
  • Such devices are known, for example, from EP0828902 or DE10113036.
  • a significant disadvantage of these toilet fresheners is that dispensing depends substantially on local flow conditions in the toilet bowl during the flushing process.
  • flow conditions can vary widely, depending on the type of toilet and positioning of the toilet freshener in or on the toilet bowl. For example, with certain toilets it is possible that no active substance is released from the toilet freshener due to no or insufficient water flowing over the toilet freshener during the flushing process, resulting in the dispensing mechanism of the toilet freshener not being initiated.
  • Toilet fresheners described in the art which supply a solid or gel-form active substance and are arranged under the rim of the toilet bowl directly in the flush water stream. Active substances are typically released from such toilet fresheners by penetration of flush water through openings in the toilet freshener, at least partially dissolving the active substances and discharging them away from the toilet freshener when the flush water exits through corresponding outlet openings.
  • the amount of flow through it can vary due to very different flow conditions locally in flush water outlet from the toilet bowl rim, resulting in only a slight release of active substances.
  • the amounts of active substance released can be influenced by the temperature of the flushing water, so that a greater release of active substance is observed in warmer months than is released in the colder months of the year.
  • a significant advantage of the toilet freshener according to the invention is that active substances are dispensed into the toilet bowl in a manner appropriate to requirements, thereby achieving active substance use which is more effective and better conserves resources.
  • a toilet freshener having at least a first container with a first preparation, wherein the container can be coupled to the dispenser of the toilet freshener.
  • the toilet freshener further includes at least one power source, a control unit and a release element and/or pump which interact in such a way that at least two different, defined amounts of at least one preparation can be released from the toilet freshener into the toilet bowl.
  • Release of a defined amount means in this connection that the amount released is independent of the amount and/or the duration of flush water flow and of the positioning of the toilet freshener in the or on the toilet bowl and is determined by the control unit of the toilet freshener.
  • toilet freshener allows for positioning of the toilet freshener in any desired way on the toilet bowl to achieve optimum active substance release relative to the amount of flush water and duration of flushing.
  • the toilet freshener according to the invention consists of various components which may in turn be combined into assemblies. These components include at least one pump, a release element, a control unit, a sensor unit, a power source, a container, a fastening means and a preparation. In a preferred embodiment, the pump, control unit, sensor unit and power source are combined into a “dispenser” assembly. The components and assemblies are described below.
  • the dispenser can include the power source needed to operate the toilet freshener, its control unit, sensor unit and at least one pump.
  • the dispenser includes a housing for protection from water splashing into the interior of the dispenser, as may occur when the toilet freshener is used in a toilet bowl.
  • the dispenser arranged on the outer rim of the toilet bowl, further enabling protection from exposure to water splashes as well as convenient operation of the dispenser.
  • the useful cross-sectional area of the toilet bowl is not reduced.
  • any component of the toilet freshener which contacts these preparations should have appropriate acid and/or alkali resistance.
  • suitable material selection should ensure that these components are as far as possible chemically inert (e.g., in relation to nonionic surfactants, enzymes and/or fragrances).
  • encapsulation materials include multicomponent epoxide and acrylate encapsulation compounds such as methacrylate esters, urethane meth- and cyanoacrylates or two-component materials comprising polyurethanes, silicones, epoxy resins.
  • a significant advantage of the invention is the separation of the toilet freshener into a dispenser and a container coupled with the dispenser, whereby the toilet freshener is flexible and adapted for the widest possible range of applications.
  • a pump is a fluid power machine for moving or delivering in particular small quantities of fluid by converting mechanical drive power into flow power.
  • Fluids are understood to be liquids and gases, and mixtures thereof and with solids.
  • Pumps include positive-displacement pumps, oscillatory pumps, diaphragm pumps, piston pumps, rotary pumps, dynamic pumps, centrifugal pumps, electrohydrodynamic pumps, electroosmotic pumps, magnetohydrodynamic pumps, surface acoustic wave pumps, capillary pumps, electrowetting pumps, thermocapillary pumps.
  • the pump is either connected directly to the power source or the control unit is interposed therebetween.
  • the release of at least one preparation can occur merely by gravity without use of a pump.
  • Release of the preparation from the container into the surrounding environment can be controlled in this configuration, for example, by a valve which opens to release the preparation and closes to prevent release.
  • the valve can be controlled directly by the power source or by the control unit connected therebetween.
  • the pump, sensor and control unit are advantageously configured so that a defined amount of active substance preparation is released into the toilet bowl irrespective of the arrangement of the toilet freshener in or on the toilet bowl and/or of the amount of flush water to which the toilet freshener is exposed.
  • the pump likewise makes it possible for at least two different, defined amounts of at least one active substance preparation to be released.
  • a significant advantage of this embodiment of the invention is that active substances are dispensed into the toilet bowl in a manner appropriate to requirements, thereby achieving active substance use which is more effective and better conserves resources.
  • the pump is configured in such a way that it is able to release an active substance preparation with a viscosity of ⁇ 5000 mPa ⁇ s.
  • Delivery rate of a micropump amounts conventionally to from 50 nl to 100 ml per minute, preferably from 250 nl to 30 ml per minute, particularly preferably from 500 nl to 5 ml per minute.
  • the micropump has a structural volume of about 5 cm 3 or less, particularly preferably of about 3 cm 3 or less, particularly preferably of about 2 cm 3 or less.
  • the specific delivery rate of a micropump (calculated from the ratio of the delivery rate to the structural volume of a micropump) is typically about 500 [l/min] or less.
  • the specific delivery rate preferably lies from 1 to 300, particularly preferably from 1.5 to 200, particularly preferably from 2 to 150, very particularly preferred from 2.5 to 100 l/min.
  • Diaphragm pumps are particularly advantageous for dispensing cleaning and active substance preparations as well as fragrances.
  • Diaphragm pumps typically include an inlet valve and an outlet valve respectively leading into and out of a pump chamber, formed in part from a pump diaphragm, and an actuator.
  • the actuator When the inlet valve is closed, the actuator causes compression of the pump chamber by acting mechanically on the pump diaphragm, whereby the fluid located in the pump chamber is conveyed out of the pump chamber via the open outlet valve.
  • the outlet valve is closed and decompression of the pump chamber is effected by the actuator, whereby the fluid is then drawn into the pump chamber via the now open inlet valve.
  • delivery direction of the micropump can be influenced or reversed.
  • the diaphragm pump actuator can be electromotive, piezoceramic, bimetallic, memory metallic, pneumatic, peristaltic, electrostatic, electromagnetic or thermal drive units.
  • the valves can be active or passive valves.
  • Passive valves include clack valves, diaphragm valves or no-moving-parts valves.
  • pressure-side release of the preparation from the dispenser can occur dropwise, as a jet or spray, by diffusion or by vaporization.
  • the container housing the preparation may be advantageous to arrange the container housing the preparation on the pressure side of the pump. In this configuration, only a fluid containing no deposit-forming substances is delivered through the pump. In this case, it is particularly advantageous to use air as the fluid.
  • the fluid is pumped into the container under pressure.
  • the container has a pressure equalizing valve which, when a defined pressure in the container is exceeded, allows the product to flow out of the container.
  • Release elements are any kind of device suitable for releasing an active substance into the surrounding environment of the dispenser.
  • Release elements can include nozzles, spray heads, droplet dispensers, foam spray heads, piezo elements, porous elements, wick systems, capillary systems, nebulizers, ultrasound nebulizers, ionization nebulizers etc.
  • Nozzles, spray heads, droplet dispensers, foam spray heads, piezo elements and the like are particularly suitable for releasing active substances into the toilet or onto the interior surfaces of the toilet bowl.
  • Nozzles, atomizers, spray heads, piezo elements, sintered plates, porous elements, wick systems and the like are particularly suitable for releasing active substance preparations into the air.
  • Release elements can have the same or different spray cone shapes when releasing the preparations. Accordingly, it is possible for one release element to produce a jet with a somewhat narrow or directed application area, while another release element produces a broad application field. Obviously, various combinations of the most varied spray cone shapes are possible.
  • the release element can be arranged in movable manner on the toilet freshener that allows the user to orient the spray cone on the release element onto a desired application field.
  • the release element can also permit adjustment of the spray cone shape.
  • the release element can also provide electrostatic charging of active substance droplets, thereby improving the wetting, adhesion and/or distribution of the active substance on a surface and/or in the air.
  • the release element can also be constructed as a fan configured either to improve air quality by drawing in malodors or optimize active substance distribution in or on the toilet bowl.
  • Release elements can further be configured so that one or more active substances are released in different directions from one another.
  • the following table provides a non-exhaustive list of some possible configurations regarding the direction of release.
  • release element in a movable manner on the clip of the toilet freshener. Doing so allows the user to orient the release element and spray cone of the preparation in order to wet a defined application field in or on the toilet with the preparation.
  • the release element(s) is/are advantageously configured so that, irrespective of the positioning of the toilet freshener on the toilet bowl, a defined amount of at least one active substance preparation is released in a directed and defined manner into the interior of a toilet bowl.
  • Advantages of such a development include more specific exposure of surfaces of the toilet bowl to one or more active substances, as well as the ability to treat different surfaces with different active substances. For example, considering a German style flat-pan toilet, the pan portion can be wetted with an active substance for reducing adhesions, while an active substance for reducing lime deposits can be applied onto the funnel-shaped walls extending from the pan to the rim of the toilet.
  • a control unit in the present application is a device suitable for influencing the transport of material, energy and/or information. To this end, the control unit acts on transducers with information which it processes for achieving the control objective.
  • Transducers include, for example, pumps and/or valves.
  • the toilet freshener does not make use of any mechanical control elements for product release, enabling the toilet freshener to be miniaturized so that it may also be used in applications in which the size of the toilet freshener is critical.
  • the control unit can include a programmable microprocessor.
  • a plurality of dispensing programs are stored in the microprocessor for selection and execution depending on the container coupled to the toilet freshener. It is also possible for the dispensing programs to be manually invoked by the user.
  • the control unit is preferably arranged on the outwardly facing side of the toilet bowl, allowing it to be operated by the user, in particular, when the user is sitting on the toilet.
  • control unit has a dispensing program for introducing at least two different active substance preparations into a toilet bowl or into the surrounding environment of the toilet bowl, wherein in at least two successive points in time t 1 and t 2 at least two different active substance preparations are released, with at least one active substance preparation introduced into the interior of a toilet bowl.
  • Such a dispensing program allows optimized cleaning performance due to control of possible chemical reactions based on appropriately time-offset release of the corresponding preparation or preparations, some examples of which are listed in the following table.
  • Cleaning product Cleaning product Cleaning product A may prevent adhesions in the toilet A in toilet bowl B in toilet bowl bowl by a protective film of cleaning product A being immediately during flushing applied in the toilet bowl immediately before the toilet is before use process used, which protective film is then flushed back off the toilet surface by cleaning product B during the flushing process.
  • Another advantage is that a controlled release of one or more different fragrances can be implemented, thereby at least reducing dependence on the sense of smell. This can be accomplished by cyclic and pulsed release of fragrance as described in the art. Furthermore, dependence on smell can also be reduced by releasing different fragrances in succession.
  • the toilet freshener can also dispense a defoamer into the toilet bowl before or during the flushing process. Excessive foaming before or during the flushing process often causes toilet paper to float on this foam so that it is not properly flushed away, but instead floats in the toilet bowl after completion of the flushing process. Consumers consider this unappealing. By dispensing the defoamer before or during the flushing process, excessive foaming can be prevented, ensuring that the toilet paper is reliably flushed away. In addition or as an alternative to the defoamer, cellulose-dissolving substances may also be added.
  • the control can be constructed so that parameters in the dispensing programs are adjustable. For example, sensor threshold values can be adjusted during preconfiguration of the toilet freshener or by the user during use in order to trigger active substance release at a specific sensor threshold value. Setting one or more parameters can be achieved by an appropriately configured input device on the toilet freshener. In this way, control of the toilet freshener may be further optimized and adapted to a specific instance of use.
  • control unit generates a control signal for releasing active substance preparation when flushing is initiated, and a control signal for terminating active substance release once flush water has stopped flowing through the toilet bowl.
  • the first amount released and at least the second amount released originate from identical or different active substance preparations.
  • the first amount released and at least the second amount released are released at different points in time.
  • the release element and at least the first preparation are configured such that a foam is formed on release of the preparation into the surrounding environment.
  • the pump, the release element and at least the first preparation are configured such that a foam is formed on release of the preparation into the surrounding environment.
  • Foaming exhibits a plurality of possible advantages.
