Definitions

  • the invention relates to a dosing unit for machine cleaning of objects with a shaped body which contains at least one cleaning agent.
  • Such a dosing unit is known from daily practice.
  • dishwashing detergents are available on the market which are designed as pressed pieces or tablets.
  • Such pressed pieces or tablets are also referred to as compacts or tabs.
  • Tabs are usually placed in a lockable dosing chamber of a dishwasher, which opens at a certain point in the washing process. The dosing unit then comes into contact with the water injected into the dishwasher, the molded body of the dosing unit slowly dissolving and the cleaning agents distributed in it being released.
  • the WO2011 / 151191 discloses a metering unit serving as a machine dishwashing detergent, the molded body of which contains polyvinylpyrrolidone particles.
  • the polyvinylpyrrolidone particles ensure that the molded body disintegrates more easily, so that the dosing unit can be used in cleaning processes that have a rinsing temperature of less than 60 degrees Celsius and a duration of less than 60 minutes.
  • the DE 10 2009 052 548 B4 discloses a detergent with a rotationally symmetrical shaped body.
  • the known metering units have the disadvantage that they are either unsuitable or costly for low-temperature washing processes with a short duration.
  • the object of the invention is to provide a cleaning agent of the type mentioned at the outset which is suitable and inexpensive for short washing processes at low temperatures.
  • the invention solves this problem in that the molded body has at least one recess to enlarge its surface.
  • a metering unit is provided, the molded body of which has recesses. These recesses increase the surface area of the molding which is effective in the washing process. Due to the enlarged surface, the dosing unit disintegrates faster than comparable dosing units without recesses. It can therefore be used in shorter washing processes and at lower temperatures. New substances that could provide a similar effect have become superfluous in the framework. The dosing unit according to the invention is therefore inexpensive. Of course, such new substances can also be used within the scope of the invention if the duration and temperature of the washing process are to be reduced even further.
  • each recess reduces the outer surface of the shaped body with which it rests against the inner wall of a metering chamber. In the context of the invention, the risk of the molded body sticking to the inner wall of the dosing chamber is therefore reduced.
  • a detergent or cleaning agent is referred to here as a cleaning agent.
  • Cleaning agents are therefore, for example, surfactants, bleaching agents, rinse aids, enzymes and the like.
  • the dosing unit is designed for a washing or rinsing cycle of a machine.
  • the metering unit is placed, for example, in a metering chamber provided for this purpose, which is equipped, for example, with a flap that pops open at a specific point in time defined by a program.
  • the dosing unit can simply be placed in the washing chamber with the items to be washed.
  • the molded body is basically made from any starting substances. It is essential that the molded body Contains at least one cleaning agent which develops its effect when an object is washed or rinsed with water.
  • the shaped body preferably has a plurality of cleaning agents which complement one another.
  • the dosage unit according to the invention preferably has a weight between 10 grams and 30 grams, in particular the dosage unit has a weight between 15 grams and 24 grams.
  • the volume of the dosing unit is designed in such a way that it fits into the chamber provided for this purpose in the machine that carries out the cleaning process.
  • the dosing unit is preferably designed for use in a washing machine or dishwasher and has a volume between 10 ml and 40 ml, in particular between 15 ml and 23 ml.
  • the shaped body is produced, for example, using granules which are inactive during washing.
  • the grains of the granules are mixed with the active ingredients and additives and then the mixture is compressed to obtain the shaped body.
  • the metering unit is advantageously equipped with a water-soluble cover.
  • low-temperature washing process should be understood here to mean washing or rinsing processes in washing machines or dishwashers that have a duration of less than 60 minutes and a washing temperature of less than 60 degrees Celsius. Such low-temperature processes are more and more required for reasons of reduced energy consumption.
  • the dosing unit according to the invention can be used in such low-temperature washing processes.
  • each recess is delimited by a cuboid, cube-shaped or a circular cylindrical outer contour.
  • Recesses of this shape can most easily be made in the molded body, for example by punching out.
  • the above-mentioned configurations of the recesses can also occur together in one shaped body.
  • At least one recess is designed as a through recess which extends completely through a section of the molded body and has an inlet and outlet opening.
  • Recesses that are open on one side absorb water during washing. However, depending on the orientation of the recess, the absorbed water may not flow off again, so that the substances absorbed by the water remain ineffective. Such an intermediate storage of water cannot occur in the case of passage recesses. Through recesses therefore accelerate the release of the cleaning agent (s) to the water flowing past.
  • the molded body has a plurality of passage recesses, each passage recess extending in a passage direction, so that all passage recesses extend in the same direction, namely the passage direction, and are aligned parallel to one another. In this way, most of the through cutouts can be made in the molded body.
  • the molded body is made of multiple layers.
  • Multi-layered or, in other words, multi-phase molded bodies are already available on the market.
  • the layers or phases are made, for example, from different starting materials and release the cleaning agents contained in them to the water flowing past them at different times.
  • the structure of a multiphase molding is known to the person skilled in the art, so that it does not need to be discussed in more detail at this point.
  • the shaped body is designed to be square in a plan view.
  • the shaped body advantageously has a plate-shaped bottom section with a trough, a round or spherical section of the shaped body being arranged in this trough.
  • the recesses are only provided in the bottom section and not in the round section. In this way, the production of the dosing unit is simplified and its costs are reduced.
  • the dosing unit is preferably a dishwashing detergent. In contrast to this, the dosing unit is a detergent for washing textile fabrics.
  • Figure 1 shows an embodiment of a known dosing unit 1 according to the prior art, which is set up for use in a dishwasher.
  • the dosing unit 1 is placed in a dosing chamber, not shown in the figures, which is part of a dishwasher, also not shown.
  • the dishwasher also has a cleaning chamber which is filled with plates, glasses of all kinds, cutlery, pots and pans as objects to be cleaned. In the course of a cleaning process, water is sprayed into the cleaning chamber several times and then sucked off again.
  • the dosing chamber is opened at a point in time so that the dosing unit stored in it comes into contact with the sprayed water.
  • the contact with water ensures that the cleaning agent (s) detach itself from the dosing unit and unfold their effect on the objects to be cleaned.
  • the metering unit 7 has a shaped body 2 with a plate-shaped bottom section 10, which has a first layer or phase 3 and a second layer or phase 4.
  • a depression 5 is formed, in which a spherical third phase of the molded body 2 is arranged as a spherical segment 6.
  • FIG. 2 shows an embodiment of the metering unit 7 according to the invention in a top view.
  • the metering unit 7 has a shaped body 2 which forms a plate-shaped bottom section 10 and also comprises two phases or layers, of which only the upper phase 4 can be seen. However, a third phase is not planned.
  • the metering unit 7 according to the invention is equipped with cuboid recesses 8, of which only the rectangular inlet openings can be seen in the top view shown.
  • Each of the six recesses 8 is delimited by an inner cuboid contour of the molded body 2, all of the recesses 8 extending in the same passage direction. In other words, the recesses 8 are aligned parallel to one another.
  • Each recess extends over the entire thickness of the shaped body 2, so that on the surface of the shaped body 2, which is formed by the in Figure 2 is facing away from the surface shown, an outlet opening is formed.
  • the outlet opening also has a quadratic contour, but is not shown figuratively.
  • the recess can therefore also be referred to as a continuous recess or through recess 8.
  • FIG Figure 3 shows a further embodiment of the metering unit 7 according to the invention, which differs from the one shown in FIG Figure 2
  • the embodiment shown differs only by the shape of the through cutouts 9.
  • the through recesses 9 are thus according to FIG Figure 3 bounded by an inner circular cylindrical contour of the molded body 2.
  • the through recesses 9 are designed to be hollow cylinders, the term cylindrical being again meant to be circular-cylindrical.
  • Figure 4 shows a further Aus accordinghungsbeispiel the invention, which largely in the Figures 2 and 3 corresponds to the embodiments shown, however, cuboid 8 and square-cylindrical 9 passage recesses occur in a mixed manner.
  • Figure 5 shows an exemplary embodiment of the metering unit 7 according to the invention, which has four cuboid-shaped passage recesses 8.
  • the molded body 2 again forms a base section 10 consisting of two phases 3 and 4, in the center of which a trough 5 is formed.
  • a spherical section 6, which is complementary in shape to the recess 5, is arranged in the recess 5 as the third phase of the molded body 2.
  • the cuboid through recesses 8 are only arranged in the base section 10, but not in the spherical section 6 of the molded body 2.
  • the dosing unit 7 according to Figure 6 has circular cylindrical through recesses 9 and otherwise corresponds to that in Figure 5 shown embodiment of the dosing unit 7.
  • Figure 7 shows a further embodiment of the metering unit 7 according to the invention, the shaped body 2 of which has a flower-shaped outer contour. Circular cylindrical through recesses 9 are made in the bottom section 10 of the molded body.
  • Figure 8 shows a further embodiment of the metering unit 7 according to the invention in a perspective view.
  • the molded body 2 of the dosing unit 7 shown here is - as in FIG Figure 7 - flower-shaped.
  • a third phase is not planned. Instead, a central hollow cylindrical through recess 9 can be seen.
