Metering system for releasing at least three different preparations during a washing programme of a washing machine

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...

Benefits of technology

This patent describes a washing machine that uses a piezoelectric element to prepare a cleaning solution before the washing program begins. The piezoelectric element acts as an acoustic or vibration sensor and an atomizer or nebulizer in a single component. The machine detects the frequency of sound waves and structure-borne noise, and converts them into an electrical signal to control the release of the cleaning solution. This helps to prevent the formation of malodors and makes it easier to remove any dirt or stains from the clothes. The washing machine can also apply a preparation onto the clothes after the washing program is complete using the vibratory atomizer.

Problems solved by technology

However, since new ingredients are only available to a limited extent and the quantity of the ingredients used per washing cycle cannot be increased at will for environmental and economic reasons, there are natural limits to this approach to solving the problem.
