Benefits of technology

[0174]It is additionally possible to apply a preparation onto the items being washed by means of the vibratory atomizer after completion of a washing program. In this case the preparation may for example be a preparation with antibacterial action or a preparation for modifying textile surfaces.
[0175]It is moreover preferable for the vibratory atomizer to take the form of a piezoelectric element.
[0179]the sensor unit and the release element are constructed as a single component.
[0180]It is very particularly preferred for the electrical signals which bring...

example 1

[0209]Example 1 shows, in the table below, a first assignment of products to three cartridge chambers. The first chamber is here configured as the first enzyme chamber, the second chamber as the second enzyme chamber, the enzyme preparations of the first and second chambers being different from one another and the third chamber being configured as a scent chamber. It is very particularly preferable for the first chamber to store at least one enzyme, selected from the group of amylases, mannanases, cellulases, lipases and / or pectate lyases and at least one surfactant and / or complexing agent at a pH value of 6-8 and for the second chamber to store at least one protease and at least one surfactant and / or complexing agent at a pH value of 6-8.

[0210]Further components of respective chambers are stated in the following table.

[0211]Chamber 1 exhibits a substantially neutral pH value of between 6 and 8, chamber 2 preferably has a substantially neutral pH value of 6-8 while chamber 3 has an ...

example 2

[0215]Example 2 differs from Example 1 in that chamber 3 additionally contains a component for improving soft handle in the form of at least one surfactant, preferably a cationic surfactant. Suitable polymers may alternatively or additionally be used for improving soft handle.

Abstract

The invention relates to a dispensing system for releasing preparations in the interior of a washing machine, comprising a dispenser and a cartridge couplable to the dispenser, in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which the first chamber stores at least one enzyme, selected from the group of amylases, mannanases, cellulases, lipases and/or pectate lyases and at least one surfactant and/or complexing agent, the second chamber stores at least one protease and at least one surfactant and/or complexing agent, the third chamber stores at least one scent and/or one optical brightener.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to a dispensing system for releasing at least three different preparations during a washing program of a washing machine.BACKGROUND OF THE INVENTION[0002]Automatic washing agents are available to consumers in numerous presentations. These automatic washing agents are typically offered for sale to the consumer in solid form, for example as a powder or as tablets, but increasingly also in liquid or gel form. For some considerable time, attention has focused on convenient dispensing of washing agents and on simplifying the operations required to carry out a washing method.[0003]Furthermore, one of the main objectives of manufacturers of automatic washing agents is to improve the washing performance of these agents, increasing attention having been paid in recent times to washing performance in low temperature washing cycles or in washing cycles with reduced water consumption. To this end, new ingredients, for example m...
