Definitions
- the invention relates to a water-carrying household appliance, in particular a household dishwasher, with a circulation pump, at least temporarily when filling of the household appliance is operated.
- Water-bearing household appliances of the type mentioned are known, e.g. from the DE-OS 40 26 868, which describes a household dishwasher in which the filling the household dishwasher continues until the circulation pump runs smoothly is reached, i.e. until enough liquid is filled in that the full pump capacity Normal operation is guaranteed.
- This approach is usually dynamic Called filling.
- the circulation pump Since the circulating pump e.g. according to DE-OS 40 26 868 is continuously operated at full pump output, the circulation pump will run for as long as possible has not yet been reached, a significantly higher noise, in particular due to noise peaks, developed than in normal operation with a sufficient amount of liquid.
- the invention is therefore based on the object in a water-carrying household appliance of the type mentioned at the outset when filling in a simple manner increased noise to avoid.
- This object is achieved in that the speed of the circulation pump is adjustable, the speed of the circulation pump during filling according to the increasing amount of water is regulated to full load operation.
- a household dishwasher according to the invention has a circulation pump which is operated at least temporarily when filling the household dishwasher. In the exemplary embodiment, this takes place in that the household dishwasher is closed Start of a cleaning program section with the use of liquid when not in use Circulation pump is filled with about 3 liters of water, which is usually called static filling referred to as. Now the circulation pump is switched on and operated at a speed, which means full load operation of the pump with about 3 liters of water. Corresponding the increasing during the filling process of the household dishwasher Water volume is now regulated the speed of the circulation pump so that there is always a full load operation stops. This continues until the maximum speed the circulation pump is reached. Since then the full load operation at the actual working point of the circulation pump can also be filled in the household dishwasher be ended.
