Method for operating a dishwasher

Abstract

A method for operating a dishwasher is provided. During a first phase, the dishwasher is operated with a first fluid quantity that is heated by a desorption process of a drying material. The first fluid quantity is increased to a second fluid quantity by adding a third fluid quantity that is stored in the drying material. During a second phase, the dishwasher is operated with the second fluid quantity. The first and second fluid quantities are circulated by a circulation pump during the first and second phases, respectively. The circulation pump is operated at a rotational speed that is higher during the second phase than during the first phase.

What is claimed is: 
     
         1 . A method for operating a dishwasher, the method comprising:
 during a first phase, operating the dishwasher with a first quantity of fluid and heating the first quantity of fluid by a desorption process of a drying material, wherein the first quantity of fluid is increased to a second quantity of fluid by adding a third quantity of fluid stored in the drying material; and   during a second phase, operating the dishwasher with the second quantity of fluid;   wherein the first quantity of fluid and the second quantity of fluid are circulated by a circulation pump during the first phase and the second phase, respectively; and   wherein the circulation pump is operated at a rotational speed that is higher during the second phase than during the first phase.   
     
     
         2 . The method of  claim 1 , wherein the dishwasher is a household dishwasher. 
     
     
         3 . The method of  claim 1 , wherein the third quantity of fluid is between 0.11 and 11. 
     
     
         4 . The method of  claim 3 , wherein the third quantity of fluid is between 0.21 and 0.51. 
     
     
         5 . The method of  claim 1 , wherein the drying material is suitable for exothermic drying. 
     
     
         6 . The method of  claim 5 , wherein the drying material is suitable for drying cleaned items. 
     
     
         7 . The method of  claim 5 , wherein the drying material is a reversibly dehydratable drying material of a sorption drying system. 
     
     
         8 . The method of  claim 7 , wherein the reversibly dehydratable drying material is zeolite. 
     
     
         9 . The method of  claim 1 , wherein, during the second phase, at least one of the first, second, and third quantity of fluid is heated by a water heater. 
     
     
         10 . The method of  claim 1 , wherein, during the second phase, the circulation pump is operated at least periodically in a true running state. 
     
     
         11 . The method of  claim 1 , wherein, during a program step of a plurality of program steps with cleaning action, the third quantity of fluid stored in the drying material is added. 
     
     
         12 . The method of  claim 11 , wherein the program step is a wash program step with addition of detergent.
