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 at least one dispenser and at least one 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 protein, one enzyme stabilizer and one surfactant at a pH value of 6-8, the second chamber stores at least one bleach, one complexing agent at a pH value of 8-10, the third chamber stores at least one scent and/or one optical brightener at a pH value of 6-8.

1 . A dispensing system for releasing preparations in the interior of a washing machine, comprising
 at least one dispenser and   at least one cartridge couplable to the dispenser,
 in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which
 a first chamber stores at least one enzyme, one enzyme stabilizer and one surfactant, 
 a second chamber stores at least one bleach, one complexing agent, 
 a third chamber stores at least one scent and/or one optical brightener, and/or one textile-softening compound. 
 
   
     
     
         2 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 6-8, the preparation in the second chamber has a pH value of 6-8 and the preparation in the third chamber has a pH value of 6-8, or of 1-3. 
     
     
         3 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 3-7, the preparation in the second chamber has a pH value of 6-8 and the preparation in the third chamber has a pH value of 6-8, or of 1-3. 
     
     
         4 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 3-7, the preparation in the second chamber has a pH value of 8-12 and the preparation in the third chamber has a pH value of 6-8, or of 1-3. 
     
     
         5 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 6-8, the preparation in the second chamber has a pH value of 8-12 and the preparation in the third chamber has a pH value of 6-8, or of 1-3. 
     
     
         6 . The dispensing system according to  claim 1 , wherein the first chamber does not contain any bleach and/or complexing agent and/or scent. 
     
     
         7 . The dispensing system according to  claim 1 , wherein the second chamber does not contain any enzyme, enzyme stabilizer, scent and/or surfactant. 
     
     
         8 . The dispensing system according to  claim 1 , wherein the third chamber does not contain any bleach, enzyme and/or enzyme stabilizer. 
     
     
         9 . The dispensing system according to  claim 1 , wherein the dispenser comprises at least one sensor for detecting the presence of water during operation of the washing machine. 
     
     
         10 . The dispensing system according to  claim 1 , wherein the dispenser comprises at least one conductivity sensor and/or temperature sensor and/or acoustic sensor. 
     
     
         11 . The dispensing system according to  claim 1 , wherein the dispenser is configured such that dispensing from the first cartridge chamber occurs in the presence of at least one sensor signal which represents the presence of water in the interior of the washing machine. 
     
     
         12 . The dispensing system according to  claim 1 , wherein the dispenser is configured such that dispensing from the second chamber is triggered after a predefined time of between 0.1 s and 30 min, after dispensing from the first cartridge chamber has taken place. 
     
     
         13 . The dispensing system according to  claim 1 , wherein the washing machine further comprises a treatment compartment, and wherein the dispenser is arranged detachably or fixedly outside the washing machine and/or outside the treatment compartment of the washing machine. 
     
     
         14 . The dispensing system according to  claim 1 , wherein the washing machine further comprises a rotating treatment compartment, and wherein the dispenser is arranged detachably or fixedly inside the rotating treatment compartment. 
     
     
         15 . The dispensing system according to  claim 1 , wherein the washing machine further comprises a dispensing drawer, and wherein the dispenser is arranged detachably or fixedly inside the dispensing drawer. 
     
     
         16 . A cartridge for use in a dispensing system according to  claim 1 , in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which
 a first chamber stores at least one enzyme, one enzyme stabilizer and one surfactant,   a second chamber stores at least one bleach, one complexing agent,   a third chamber stores at least one scent and/or one optical brightener, and/or one textile-softening compound.   
     
     
         17 . A method for releasing preparations in the interior of a washing machine, comprising
 at least one dispenser with at least one sensor, which is suitable for detecting the presence of water in the interior of the washing machine and   at least one cartridge couplable to the dispenser,
 in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which
 a first chamber stores at least one enzyme, one enzyme stabilizer and one surfactant, 
 a second chamber stores at least one bleach, one complexing agent, 
 a third chamber stores at least one scent and/or one optical brightener, and/or one textile-softening compound. 
 
   wherein
 dispensing from the first cartridge chamber occurs in the presence of at least one sensor signal which represents the presence of water in the interior of the washing machine, and 
 dispensing from the second chamber is triggered after a predefined time of between 0.1 s and 15 min after dispensing from the first cartridge chamber has taken place.
