Definitions

  • the invention relates to a device and a method in a household appliance, in particular a dishwasher, with a humidity sensor for detecting the degree of dryness within a container or air duct of the household appliance.
  • the rinsing liquid is pumped off after the last rinse and the heating of the dishwasher is switched on for a fixed period of time.
  • the atmosphere in the dishwasher container stored therein items is heated so that it gives off increased moisture during the dry phase.
  • the humidity condenses on the cooler inner walls of the washing container and eventually runs off to the dishwasher sump.
  • the duration of heating is determined independently of the loading of the dishwasher and thus leads to an inefficient drying process, in which sometimes unnecessary heating energy is consumed.
  • the household appliance has a humidity sensor for detecting the degree of dryness within a container or air duct.
  • the humidity sensor detects the humidity of the atmosphere either directly within the container or in an air duct, which is in communication with the container. Through the air duct, for example, during the dry phase, the air circulates out of the container and the air moisture transported through the air duct is separated by means of a condensation device or discharged from the domestic appliance.
  • the humidity sensor detects the moisture adhering to it from a defined detection surface in the interior of the container or the air duct.
  • the humidity from the container interior of the household appliance is reflected at the detection surface in the form of condensation droplets or a moisture film. By detecting the moisture on the detection surface is determined whether the dry phase has progressed so far that the humidity from the container interior is already largely removed.
  • the detection surface With decreasing humidity, the detection surface also dries, so that in the absence of the moisture film or the drops on the detection surface on the end of the drying phase can be closed. This can be switched off at a reproducible degree of humidity in the container, the drying heater and possibly a circulating air blower. If, for example, a large number of items to be washed is disposed of in a dishwashing machine, this releases moisture to the dishwashing atmosphere for a longer period of time The moisture adheres to the detection surface for longer. Therefore, a longer drying phase is carried out until complete drying of the dishes. Few items to be washed accordingly less moisture to the Spülraumatmospreheat from and the moisture on the detection surface dries faster, so that based on the moisture detection, the drying phase is turned off earlier. The same applies, for example, to a tumble dryer depending on the loading state or the residual moisture of the laundry to be dried.
  • the detection surface is an inner surface of a defined wall portion of the container or the air channel, so no additional area within the household appliance for moisture detection must be provided.
  • the defined wall region is a plate element, which is arranged in or on an opening of the container or channel wall.
  • the plate element is connected by means of welding, thermal welding, gluing or by means of a sealing sleeve with the adjacent container or channel wall. This results in a tight and easy to install connection between the container or channel wall and the plate member.
  • the plate member is a glass sheet or a transparent plastic sheet, optical detection of the moisture on the detection surface is enabled. Depending on the optical wavelength during measurement is the plate element in the visible range, in the UV range or in the infrared range permeable.
  • the detection surface is assigned a condensation device.
  • the condenser accelerates the condensation of moisture on the detection surface by cooling it.
  • the detection surface is colder than the surrounding surface inside the container or the air duct and the existing humidity is reliably detected by the condensation.
  • the detection surface is in thermal contact with a Peltier element. The Peltier element is operated during the dry phase and extracts heat from the detection surface.
  • the detection surface communicates with a condensation device which is present anyway for accelerating the drying, for example a water container or a condensation dryer. By such a condensation device, the drying process is accelerated while removing heat of the detection surface.
  • a wear-free, non-contact sensing sensor By optically detecting the moisture adhering to the sensing surface, a wear-free, non-contact sensing sensor is provided. Especially in the case where the humidity sensor is disposed outside the atmosphere containing atmospheric moisture, the sensor is subject to a low thermal and chemical stress. In a dishwasher, the sensor is advantageously arranged and operated outside of the aggressive Spülraumatmospreheat.
  • the humidity sensor on a light sensor which detects a caused by the adhering moisture change in the lighting conditions. If no external light source (for example ambient light) is available in a container which is enclosed on all sides, the light to be detected by the light sensor is advantageously generated by a light source.
  • the light source and the light sensor are arranged at a distance from one another, wherein the light emitted by the light source passes to the light sensor after the reflection on the surface of the detection surface. In the presence / absence of a moisture film or drops on the detection surface, the reflection on the surface of the detection surface changes such that the intensity of the reflected light changes due to the humidity and this change is evaluable as the presence / absence of moisture.
  • the refractive index of air and the refractive index of the moisture a total reflection is achieved in the dry phase, in which maximum intensity occurs on the light sensor, while in the presence of a moisture film, the intensity is reduced by reflection losses , Or the total reflection is achieved conversely in the presence of moisture and in the absence of moisture, the intensity is attenuated by reflection losses.
  • At least one reference value for the Set and save maximum light intensity This may be done at the factory or during operation of the dishwasher at appropriate times and at various intervals.
  • the reference value of the intensity maximum is required in order to be able to calculate the reflection losses from the measured light intensities during the process and to draw conclusions for the required heating demand.
  • the measured values of the light intensities are transmitted to a control unit and evaluated there according to predetermined algorithms.
  • various evaluation methods are applicable, for example, a table be deposited, the average values of light intensity minimum residual maturity assigns the heating and / or heating demand, on the other hand, the drying process can be determined from the rate of change of the light intensities.
  • a combination of different evaluation methods is conceivable, the other parameters used during dishwasher operation. Depending on the selected evaluation method of the measurement results, it may be useful in terms of minimizing the heating demand, the heating continuously or clocked on and / or off.
  • the contiguously incoming measured values of the light intensity are averaged and recourse is made to a stored remaining running time of the heating, then it may be expedient to switch off the heating only after the remaining heating time has expired, if the measured light intensities after expiry of the predefined residual running time lie within a tolerance interval of the heating time
  • There is a clocked operation of the heater is driven, which is clocked in terms of its duration and its performance, so that in phases of low or no heating power, it is possible to compare the measured values of light intensity with its predetermined reference value, so a appropriate time to shut down the heater to determine.

  • the glass plate 12 is at its edge region with a elastic adhesive (not shown) adhered to an adjacent to the opening 11 inner wall 14 of the washing container 1.
  • the elastic adhesive compensates for stresses due to temperature changes during operation of the dishwasher between the glass plate 12 and the inner wall 14.
  • the measuring head 13 is formed in two parts from a Peltier element 15 and a detector element 16. In another embodiment, not shown here, the Peltier element 15 may also be integrated directly into the detector element 16, so that the measuring head 13 is integrally formed.
  • the Peltier element 15 and the detector element 16 are connected via a combined measuring and control line 17 with an in Fig. 1 shown control unit 18 connected to the signal evaluation.
  • the Peltier element 15 cools the area adjacent to the detector element 16 surface of the glass plate 12 and thereby preferably supports the condensation on the glass plate 12.
  • the moisture on the glass plate 12 evaporates only when almost all the humidity is removed from the rinsing atmosphere in the washing compartment 1 ,
  • Fig. 3a shows a detailed view of the detector element 16.
  • a light-emitting diode 20 and a photodiode 21 are arranged in a common housing of the detector element 16.
