Method for operating a water-conducting domestic appliance
View Patent ↗A method for operating a water-conducting domestic appliance, including a domestic dishwasher, wherein the water-conducting domestic appliance includes a program controller for performing a plurality of sequential program steps and the program controller operatively interacts with at least a detergent-dosing system, the method including the step of adding at least one cleaning substance having a function during at least one program step.
1. A method for operating a water-conducting domestic appliance, wherein the water-conducting domestic appliance includes a program controller for performing a plurality of sequential program steps and the program controller operatively interacts with at least a detergent-dosing system, the method comprising a first program step including a cleaning phase in which an alkali carrier together with at least one of a first dispersing substance and a first complexing substance are added, the cleaning phase including at least two enzymes added at times separated by a time interval, the method comprising a second program step of clear rinsing in which at least one of a second dispersing substance and a second complexing substance are added, and after adding the at least one of the second dispersing substance and the second complexing substance, a bleach, a bleach activator and a surfactant are added in separate applications.
2. The method according to claim 1 wherein at least one of the at least two enzymes is operable to break down at least one of starch compounds and polysaccharides.
3. The method according to claim 1 wherein at least one of the at least two enzymes is operable to break down at least one of proteins and peptides.
4. The method according to claim 1 wherein at least one of the at least two enzymes is operable to break down fatty compounds.
5. The method according to claim 1 further comprising adding at least partially complex alkaline earth ions.
6. The method according to claim 1 wherein at least one program step is executed under sensor control.
7. The method according to claim 1 wherein the first program step includes a pre-wash program step, which comprises adding at least one of the at least two enzymes and a surfactant.
8. The method according to claim 1 wherein the method includes an intermediate wash program step wherein another alkali carrier and at least one of another dispersing substance and another complexing substance are added.
9. The method according to claim 1 wherein the clear rinsing program step includes adding an additional alkali carrier.
10. The method according to claim 1 wherein the method includes a disinfecting program step.
11. The method according to claim 1 wherein the first program step includes adding a biocidal fluid.
12. The method according to claim 1 wherein at least one of the first program step and second program step includes adding a glass-protecting corrosion inhibitor.
13. The method according to claim 12 wherein the first program step includes adding the glass-protecting corrosion inhibitor containing at least zinc salt.
14. The method according to claim 12 wherein the second program step includes adding the glass-protecting corrosion inhibitor.
15. The method according to claim 12 wherein the alkali carrier in the first program step is sodium hydroxide, which functions to increase a pH value, and wherein the first program step includes adding the glass-protecting corrosion inhibitor after a time interval with respect to adding the sodium hydroxide, adding the at least two enzymes, and adding the first complexing substance.
16. A method for operating a water-conducting domestic appliance, wherein the water-conducting domestic appliance includes a program controller for performing a plurality of sequential program steps and the program controller operatively interacts with at least a detergent-dosing system for adding materials to a wash liquor, the method comprising:
adding, in a pre-wash phase, an alkali carrier together with at least one of a first dispensing substance and a first complexing substance to the wash liquor, then
performing a cleaning phase in three stages, wherein a first stage comprises adding an enzyme amylase, a second stage, after a first time interval from the first stage, comprises adding an enzyme protease, and a third stage, after a second time interval from the second stage, comprises adding a second alkali carrier; then
circulating the wash liquor in a wash phase; and then
performing a rinse phase in multiple stages including adding at least one of a second dispensing substance and a second complexing substance, then subsequently adding a bleaching agent, then subsequently adding a bleach activator, and then subsequently adding a non-ionic surfactant.
