Definitions
- the invention relates to an apparatus and a method in a household appliance, in particular a dishwasher, with a moisture sensor to record the degree of dryness inside a container or air duct of the household appliance.
- the rinsing liquid is pumped out and Heating the dishwasher for a set period of time switched on.
- the atmosphere in the In the dishwasher container the items to be stored are heated up, so that this increased during the dry phase Releases moisture.
- the humidity condenses the cooler inner walls of the rinse tank and runs finally down to the dishwasher sump.
- the Heating time regardless of the load on the dishwasher fixed and thus leads to an inefficient Drying process, in which heating energy is sometimes unnecessary is consumed.
- the household appliance has a moisture sensor for recording the degree of dryness within a container or air duct.
- the moisture sensor detects the atmospheric humidity either directly inside of the container or in an air duct that communicates with the container communicates. Through the air duct, for example the air from the container during the drying phase circulated and transported through the air duct Air humidity by means of a condensation device deposited or left out of the household appliance.
- the Moisture sensor detected from a defined detection area inside the container or the air duct, the adhering there Humidity. During the heating and / or drying phase the humidity comes out of the inside of the container of the household appliance in the detection area in the form drops of condensation or a film of moisture. By detecting the moisture on the detection surface it is determined whether the dry phase so far is advanced that the air humidity from the inside of the container is already largely removed.
- the detection area dries also from, so that in the absence of the moisture film or the drop on the detection surface on the end the drying phase can be closed. So that can with a reproducible level of moisture in the container the drying heater and, if necessary, a circulating air fan are switched off become.

It stands in one container enclosed on all sides no external light source (e.g. ambient light) is available, so it is advantageous the light to be detected by the light sensor through a light source generated.
- the light source and the light sensor are spaced arranged from each other, the one from the light source emitted light after reflection on the surface the detection area reaches the light sensor. In the presence / absence of a moisture film or The reflection changes from drops on the detection surface on the surface of the detection surface such that 'the intensity of the reflected light through the Moisture changes and this change as the presence / absence moisture can be evaluated.
- this with a moist or dry condensation surface the incoming light from the light source totally reflected is at least a reference value for that Specify and store the maximum of the light intensity. This can be done at the factory or while the dishwasher is in operation at appropriate times and in different Time intervals are repeated.
- the reference value of the Intensity maximums are required during the procedure the reflection losses from the measured light intensities to be able to calculate and draw conclusions from these for the required heating needs.
- the measured values of the Light intensities are transmitted to a control unit and evaluated there according to predetermined algorithms.
- Evaluation method can be a table be stored, the mean values of the light intensity Minimum remaining terms of heating and / or heating requirements assigns, on the other hand, the drying process determined from the rate of change of the light intensities become.
- the other during dishwasher operation uses certain parameters. Dependent on the selected evaluation method of the measurement results, may it be in terms of minimizing the Heating needs be sensible, the heating continuously or switched on and / or off. E.g.
- the continuous incoming measured values of the light intensity averaged and from these to a deposited remaining term of Heating is used, so it can after this Remaining running time of the heating may be sensible, if the measured light intensities after expiration the specified remaining term is within a tolerance interval of the specified reference value or it will a clocked operation of the heater is driven, the regarding its duration as well as its performance is timed that in phases of little or no heating power it is possible is, the measured values of light intensity with their given Compare reference value so as to find a suitable one Determine when to switch off the heating.
