Rinsing method for a water-bearing domestic appliance, especially dishwasher
View Patent ↗A rinsing method for a water-conducting domestic appliance is provided in which rinsing liquid is heated to a first temperature in a first operating mode in at least one partial program step of a first rinse cycle; a scale formation in the water-conducting domestic appliance is recorded by a scale sensor arranged in a hydraulic system; the scale formation is compared with a nominal value for the scale formation; and, upon exceeding the nominal value, a second rinse cycle is executed in a second operating mode, while the rinsing liquid is heated to a second temperature that is higher than the first temperature.
1. A rinsing method for a water-conducting domestic appliance, the method comprising:
heating rinsing liquid to a first temperature in a first operating mode of at least one partial program step of a first rinse cycle;
recording a scale formation in the water-conducting domestic appliance by a scale sensor arranged in a hydraulic system;
comparing the scale formation with a nominal value for the scale formation; and
upon exceeding the nominal value, executing a second rinse cycle in a second operating mode, during which the rinsing liquid is heated to a second temperature that is higher than the first temperature.
2. The rinsing method of claim 1 , wherein the water-conducting domestic appliance is a dishwasher having a drying unit with a reversibly dehydrated drying agent.
3. The rinsing method of claim 1 , wherein the scale formation includes at least one of grease deposits and/or deposited soiling.
4. The rinsing method of claim 3 , wherein the second temperature of the partial program step that is performed in the second operating mode is increased such that the one of grease deposits and deposited soiling in the hydraulic system are dissolved, and wherein the second temperature is increased to a range of 60° C. to 65° C.
5. The rinsing method of claim 1 , wherein the at least one partial program step, which is operated in one of the first and second operating modes, is a washing step, in which the first and second temperatures correspond respectively to the washing temperature.
6. The rinsing method of claim 5 , wherein the first and second temperatures of the at least one partial program step, which takes place before or after the washing step, are lower than a respective first or second washing temperature.
7. The rinsing method of claim 6 , wherein the at least one partial program step includes one of a pre-rinsing step, an intermediate rinsing step, a rinsing step and a drying step.
8. The rinsing method of claim 7 , wherein, in the drying step, air present in a washing compartment is directed through a drying unit having a reversibly dehydrated drying agent.
9. The rinsing method of claim 8 , wherein the air is directed from the drying unit back into the washing compartment.
10. The rinsing method of claim 8 , wherein, in a regeneration process, a quantity of water stored in the reversibly dehydrated drying agent is directed into the washing compartment as heated steam, which heats the rinsing liquid to a predetermined temperature in the washing step.
11. The rinsing method of claim 1 , wherein the rinsing liquid is heated to the predetermined temperature by a water heater provided in a rinsing liquid circuit, and wherein the rinsing liquid is further heated to the one of first and second temperatures.
12. The rinsing method of claim 1 , wherein the first temperature in the first operating mode is in the order of 45° C. to 55° C., and wherein the second temperature in the second operating mode is in the region of 60° C. to 65° C.
