Definitions

  • the invention relates to a domestic dishwasher with at least one rinsing liquor pump and at least one sorption drying device, whose one or more electrical components can be controlled by at least one control / control device.
  • air which flows through the sorption drying material is heated with the aid of at least one heating device to such high temperatures that liquid stored in the sorption drying material, in particular water, emerges as completely as hot steam.
  • the expelled water vapor is taken from the air flow generated by the blower in the washing.
  • the sorption drying material dried in this way is then reprocessed, ie regenerated, for the next drying step, for example of a subsequent dishwashing program.
  • the air heated by the heating device during the respective desorption process can additionally be used for washing liquor, air and / or washware in the washing container for at least one washing process and / or cleaning process such as a newly started dishwashing program for the respective desorption process warm warm air flow with warm up or heat up. This enables energy-efficient cleaning and drying of items to be washed.
  • the invention is based on the object to show a way how a household dishwasher with at least one Sorptionstrocknungs responded can be operated largely reliable.
  • This object is achieved in a household dishwasher of the type mentioned above in that the control / control device derives at least one control signal for adjusting the one or more electrical components of the Sorptionstrocknungs adopted from the volume flow caused by the respective Spülflottenpumpe.
  • control / control device derives at least one control signal for adjusting the one or more electrical components of the sorption drying device from the respective volume flow caused by the rinsing liquor pump makes it possible to control the sorption drying device in a functionally reliable manner during the respective sorption and / or desorption process to be able to adjust.

  • the specific interaction of the one or more operating parameters of the one or more electrical components of the sorption drying device can be coordinated such that the sorption drying device can be safely operated in a desired, permissible operating range during its respective sorption process and / or desorption process.
  • the sorption drying device comprises at least one sorption container with reversible dehydrogenatable sorption drying material.
  • This allows a space-saving and material-saving housing of sorption drying material, which is sufficient for a perfect Sorptionstrocknungsvon.
  • the sorption drying device further advantageously has at least one fan unit and at least one heating device associated with the sorption container, in particular an air heater. As a result, a largely flawless, material-friendly desorption of the sorption drying material can be ensured.
  • control / control device can use the electric current respectively taken up by the rinsing liquor pump as a measurement criterion for the respective volume flow and at least one control signal for adjusting the one or more electrical components of the sorption drying device from this electric current drawn by the rinsing liquor derived.
  • This measurement parameter is readily available in the controller.
  • a rinsing liquor pump with a controllable or controllable electric motor preferably a so-called BLDC ("brushless direct current") rinsing liquor pump, ie a brushless DC motor pump, as a setting parameter Flush liquor volume, ie Spülflotten just prepared, as operating load in an unambiguous manner, in particular substantially in a directly proportional manner depends on the detected electric current is a measurement criterion for the rinsing liquor pump pumped through the wash liquor volume flow and thus possibly also indirectly for the total volume of wash liquor in the liquid circulation system It is therefore not necessary to provide a sensor specifically for determining the rinsing liquor volume in the circulation system or the rinsing liquor throughput of the rinsing liquor pump.
  • BLDC brushless direct current
  • the control / control device switches according to an advantageous development of the invention, the Sorptionstrocknungs featured one or more electrical components, in particular all their electrical components, by means of the control signal.
  • the heating device and possibly also the fan unit of the sorption drying device will not even be switched on. If the desorption process has already been started, in this case the already started desorption process is deactivated and the heating device and possibly also the fan unit are switched off. By deactivating, in particular, the heating device, inadmissibly high thermal stresses on the sorption drying material in the sorption container of the sorption drying device, which could occur during the desorption of the sorption drying material, can be reliably avoided. This provides thermal protection of the sorption container with the sorption drying material.
  • the rinsing liquor circulation system of the dishwashing machine has such a large rinsing liquor quantity that it suffices to cool the air blown into the rinsing container from the sorption container of the sorption drying apparatus during the respective desorption process, the impermissible thermal stresses or even damage to components of the desiccant Dishwasher of the dishwasher, and / or to be dried items in the Washing containers are largely avoided.
  • the minimum volume flow may be approximately equal to or less than half the rated operating volume flow of the rinsing fluid pump, in particular between 5 and 171 / min, preferably approximately 161 / min.
  • a circulating pump is provided in the rinsing liquor circulation system of the dishwasher as a rinsing liquor pump.
  • This circulating pump makes it possible to obtain in a simple and reliable manner indirectly via the electric current drawn by it depending on the load state, clear information about the rinsing liquor volume flow pumped through it and therefore possibly also in particular about the total volume of rinsing liquor present in the rinsing liquor circulation system.
  • the control / control device has at least one main control device and at least one additional control unit, which are connected to one another via at least one control line, in particular a data bus.
  • the additional control unit is specific to the heating device and / or the fan unit of the sorption drying device, ie is assigned specifically.
  • the additional control unit may be appropriate for the additional control unit to switch off the fan unit of the sorption drying device after the switch-off time of the heating device only after a predefinable overrun time has expired.
  • the heating device and / or the sorption drying material in the sorption container of the sorption drying device can continue to be traversed by air.
  • heat can be removed from the heating device and / or from the sorption container so that overheating in the region of the heating device and / or the sorption container is largely avoided.
  • This continued operation of the fan unit is particularly advantageous because the sorption drying material reacts slowly in its heating process during desorbing due to its heat storage capacity and stores heat.
  • the fan unit is therefore expediently further operated beyond the switch-off time of the heating device, that sufficient heat energy from the Sorptionstrocknungsmaterial and the sorbent is removed by the continued air flow, so that material damage of Sorptionstrocknungsmaterials, undue stress on the heater and the other components of the sorption and the sorbent surrounding components or components of the dishwasher are largely avoided. Due to the continued air circulation by means of the fan unit, a cooling of the sorption drying material in the sorption container and / or the heating device is ensured accelerated. Without the continuation of the fan unit, however, it could lead to a heat accumulation in the sorption, which could lead to unacceptably high temperatures.
