Definitions

  • the invention relates to a device for portioned storage and gradual dispensing of liquid product, in particular liquid detergent, into the washing water of a washing machine and a method for its use.
  • washing machines Since the induction troughs of commercially available washing machines are now designed to hold washing powder, considerable difficulties arise for the use of liquid products, in particular liquid detergents, in washing machines.
  • liquid detergent In contrast to washing powder, which is gradually rinsed into the washing drum with the incoming water in the induction troughs of washing machines and also dissolves evenly there, liquid detergent either flows immediately into the washing machine or is immediately rinsed into the washing machine with the incoming water. This affects the washing result to a considerable extent, since the liquid detergent is not distributed evenly in the washing machine drum, but rather accumulates to a large extent on the floor or in the drain device of the washing machine. This can also have the consequence that more liquid detergent than necessary is metered into the induction channel by the users, which makes the washing process less economical and less environmentally compatible.
  • liquid detergents can be found in the usual induction channels washing machines, in contrast to washing powder, do not store or store them for the pre-wash and main wash cycle.
  • a spherical device has been proposed in DE-OS 35 12 083, which is placed on the laundry in the washing machine drum and gradually releases the detergent during the washing process.
  • This device has the disadvantages that, on the one hand, the laundry comes into contact with the concentrated liquid detergent, so that there is the risk that after the washing process, detergent residues remain in the laundry or spots that are lightened like spots on the washed textiles.
  • this device is not suitable for use in two-eye processes, for example in the case of a preliminary and subsequent rinse cycle, since liquid detergent always escapes from the device into the washing drum due to the unlocked device, as long as liquid detergent is still contained in the device.
  • the object of the invention is to provide a solution which provides a portioned storage of liquid product, in particular liquid detergent, in the washing machine's washing trough allows its gradual and even release into the water flowing into a washing machine.
  • the object is achieved according to the invention by a porous, in particular trough-shaped or bag-shaped insert for insertion into the washing machine's washing trough.
  • a dosing aid is created which, after filling with the liquid product, releases it gradually and uniformly into the inflowing washing water.
  • the liquid product is evenly distributed in the wash liquor and there is no longer any risk that liquid product will settle on the floor or in the drain device of the washing machine.
  • the laundry does not come into contact with liquid detergent in a concentrated form, so that no brightened stains can occur, and the device can be filled with a product quantity which is sufficient for a two-eye process. Due to the design and arrangement of the device according to the invention in the induction channel of a washing machine, only liquid product gets into the washing drum when washing water also flows in. This means that a sufficient amount of liquid detergent can be stored to carry out a two-eye process.
  • the invention provides that the walls of the insert consist of open-cell foam, filter paper or nonwoven. These materials have a sufficiently high inherent stiffness to form the trough-shaped or bag-shaped insert and have a porosity which ensures the gradual and uniform penetration and outflow of the liquid product.
  • the walls of the insert are designed in their porosity in such a way that the porous walls Both water and dilute liquid product can be penetrated, as the invention further provides.
  • the viscosity of the liquid product in the insert is reduced by the water penetrating into the porous insert, so that the liquid product can gradually and completely emerge from the insert.
  • the open-cell foam has a bulk density of 10 to 100 kg / m3 and a pore volume of over 80%, as is also provided by the invention.
  • the walls prefferably expedient for the walls to be designed to be entirely porous, as is also provided by the invention. This design creates the largest possible outlet area for the liquid product.
  • the above-mentioned object is achieved according to the invention in that a porous, tub-shaped or bag-shaped insert is introduced into the washing machine groove and filled with liquid product and then the washing process is started.
  • the invention provides that a trough-shaped insert with walls made of open-cell foam or a bag-shaped insert with walls made of filter paper or nonwoven is introduced.
  • tub-shaped inserts made of open-cell foam and bag-shaped inserts made of nonwoven fabric or filter paper are particularly suitable for production-technical reasons, since they can each be produced without great and complicated technical effort and, in the spatial form described, have the necessary inherent stiffness and resistance to the wash water.
  • these spatial shapes are particularly suitable for insertion into the washing machine's washing troughs.
  • the invention expediently provides that inserts with walls made of open-cell foam or nonwoven are reused several times.
  • the five walls 2, 3, 4, 5, 6 forming the tub-shaped insert which is denoted overall by 1 in FIG. 1, consist entirely of porous, open-cell foam. Insert 1 is open at the top.
  • the open-cell foam can be made, for example, from polyurethane, modified polyvinyl alcohol, imide foams or viscose. It has a bulk density of 10 to 100 kg / m3 and a pore volume of over 80%.
  • FIG. 2 shows an insert, designated overall by 7, whose walls 8, 9 consist of filter paper.
  • the walls 8, 9 are connected to one another on the side surfaces of the bag-shaped or envelope-shaped insert 7 by means of embossed strips or adhesives.
  • the filter paper has a weight of 84 g / m2 and a filtration time of 1500 s (Herzberg test system).
  • Both the insert 1 and the insert 7 can also be made of nonwoven.
  • the inserts 1 and 7 are matched to the amount of liquid product that they are to hold in their interior spaces 11 or 12 and the dimensions of conventional washing-in troughs in washing machines in which they are to be used.
  • the porosity of the insert 1 or 7 is matched to the liquid product in such a way that undiluted or concentrated liquid product cannot, but liquid product diluted by the entry of water can nevertheless escape through the walls.
  • the inserts 1 or 7 are introduced into the washing machine's washing-in trough and their interiors 11 and 12 are filled with liquid product. After switching on the washing process and the penetration of water into the interior 11, 12, whereby the liquid detergent contained therein is diluted, the liquid product then gradually and evenly through the porous walls 2 to 6 or 8 and 9 in the in the induction channel of Washing machine flowing wash water out.
  • the priority of the walls can also be designed so that even undiluted liquid detergent can escape slowly and gradually.
