20110146718 | DOMESTIC DISHWASHER WITH A SORPTION DRYING DEVICE AND CORRESPONDING METHOD - A domestic dishwasher is provided, which has a main controller, a sorption drying device, and an additional controller to specifically control an electrical component of the sorption drying device. | 06-23-2011 |
20110213505 | HOUSEHOLD APPLIANCE HAVING AN AIR DRYING DEVICE AND/OR FLUID HEATING UNIT, AND ASSOCIATED METHOD - A household appliance, particularly a household dishwasher, washing machine, clothes dryer, or the like, includes an air drying device and/or fluid heating device, connected to an electrical energy supply network. At least one control/monitoring unit is provided to detect any deviation of an actual value of at least one characteristic of the electrical energy supply network from a target value and to generate at least one control signal for setting an electrical component of the member in response to a detected deviation of the actual value. | 09-01-2011 |
20120006355 | DISHWASHER - A dishwasher, in particular a domestic dishwasher, includes at least one activatable circulating pump for directing liquid against food-soiled items to be cleaned, at least one activatable drain pump for discharging a minimum liquid volume of an operating liquid volume from a pump well of the dishwasher, and a filter unit for preventing soil particles contained in the liquid from reaching the circulating pump. After the drain pump has been activated for discharging the minimum liquid volume and then deactivated, the circulating pump can be activated and an operating parameter evaluated to determine whether there is a residual liquid volume remaining in the dishwasher. | 01-12-2012 |
20120009074 | WATER-CONDUCTING HOUSEHOLD APPLIANCE, PARTICULARLY A DISHWASHER - A water-conducting household device, particularly a dishwasher, includes a pump having at least one normal operating mode in which fluid is pumped in a pumping direction, and a venting operating mode which can be carried out before the normal operating mode. The venting operating mode is provided to allow venting of the pump by pumping a gas bubble in opposition to the pumping direction during the normal operating mode at least partially out of a pump chamber of the pump to a fluid pump inlet of the pump. | 01-12-2012 |

20130032171 | DISHWASHER WITH A SCREEN SYSTEM - A dishwasher includes a controller controlling a cleaning cycle, a screen system for filtering a wash fluid, a circulation chamber and a collection chamber in fluid communication with the circulation chamber via a screen arrangement, a circulation pump for circulating the wash fluid and a drain pump for pumping out the wash fluid. During the cleaning cycle, to detect blockage in the screen arrangement, a degree of transmission in the circulation chamber filled with wash fluid is determined with an optical turbidity sensor in a first measuring step. The wash fluid is then pumped out of the collection chamber and the degree of transmission in the circulation chamber is again determined in a second measuring step. The change in the degree of transmission from the first measuring step to the second measuring step is then evaluated. | 02-07-2013 |
20130048025 | DISHWASHER WITH FAULT IDENTIFICATION - A dishwasher includes a control facility for executing a wash cycle for cleaning items held in a wash chamber which is filled with water via a water inlet facility having an inlet valve operably connected to the control facility. To identify malfunction of the water inlet facility, the control facility executes an identification sequence which includes a test filling phase, in which the inlet valve is opened for a period corresponding to a predefined time value. A detection facility detects during operation of a recirculation pump to recirculate water in the wash chamber at least one operating parameter corresponding to a quantity of water in the wash chamber at an end of the test filling phase. The control facility determines a water flow into the wash chamber during the test filling phase from the detected operating parameter and compares the determined water flow with a minimum water flow. | 02-28-2013 |
20130220374 | METHOD FOR OPERATING A WATER-CONDUCTING DOMESTIC APPLIANCE - A method for operating a water-conducting domestic appliance, such as a dishwasher, includes filling the water-conducting domestic appliance with a minimum amount of filling water that is circulated by a pump, and checking a water flow diverter for malfunctions and determining from an operational parameter of an electromotor that drives the pump whether the pump runs smoothly, thereby indicating whether the quantity of filling water corresponds to at least a nominal quantity of filling water. When the water flow diverter is not malfunctioning, the pump is again checked for smooth running or a refilling step is carried out to increase the minimum amount of filling water. Conversely, when the water flow diverter is malfunctioning, the check for smooth running or the refilling step are omitted. | 08-29-2013 |
