  • This feature of the controller paired with the corresponding board surface can advantageously also be used for a filling height measurement of stationary or liquid media. Decisive in both methods is the sensitive reaction to changed The dielectric constant near the capacitor surface.
  • the property according to the invention can be advantageously used to construct a system-separated sensor (preferably completely sealed to the medium / liquid).
  • This application can e.g. also be performed on control units or printed circuit boards of Kombidosier marn or other devices of household appliances to detect liquid / media presence or media flow.
  • a drying unit of the domestic appliance comprises the microcontroller or sensor according to the invention With the absorbed water from the last drying enriched solution or hygroscopic liquid expelled and / or heated until advantageously the original or primary degree of filling (level or pressure measurement) is reached.
  • the heating for expulsion according to the invention is not timed (flat rate) as, but regulated in particular by this detected level reference point.
  • the system according to the invention can respond advantageously to differently absorbed amounts of water as needed, which is not possible in a zeolithic system according to the prior art (in the absence of affordable suitable sensors). Therefore, previous zeolitic systems are only time-controlled.
  • a storage reservoir of the hygroscopic liquid comprises a heating unit for heating the hygroscopic liquid.
  • a concentration or regeneration of the hygroscopic liquid is achieved after the absorption of water from the drying air to be dried.
  • another regeneration of the hygroscopic liquid could be provided, such as by means of a centrifuge and / or a semi-permeable membrane for separating the collected water.

  • the secondary circuit comprises a heating device for heating the drying air.
  • a hygroscopic withdrawal agent or storing the hygroscopic liquid in a reserve store.
  • a substance is hygroscopic if it can bind moisture from the environment, eg from the surrounding air. This deprivation of moisture can be an exothermic process in which heat energy is released.
  • the drying air must be able to come into direct contact with the hygroscopic withdrawal agent.
  • the released during the exothermic removal of moisture heat energy is further used, thus enabling a higher heat utilization.
