Description

Die Erfindung betrifft eine Heizeinrichtung für ein Haushaltsgerät.The invention relates to a heating device for a Household appliance.

Bei Haushaltsgeräten, wie Waschmaschinen oder Geschirrspülmaschinen, sind elektrische Widerstandsbeheizungen zum Aufheizen von Wasser bzw. Lauge oder Trocknungsluft vorgesehen. Bei Waschmaschinen oder Geschirrspülmaschinen sind diese Beheizungen als Rohrheizkörper oder als Durchlauferhitzer ausgebildet. Werden Rohrheizkörper verwendet, dann muss der Bottich der Waschmaschine bzw. der Spülbehälter des Geschirrspülers entsprechende Durchführungs-Durchbrüche aufweisen. Sind Durchlauferhitzer vorgesehen, dann sind Rohrleitungen bzw. Schläuche erforderlich, um den Durchlauferhitzer in den Wasserkreislauf einzubinden.For home appliances, such as washing machines or Dishwashers, are electric Resistance heaters for heating water or Lye or drying air provided. For washing machines or dishwashers are these heaters as Tubular heater or designed as a water heater. If tubular heaters are used, then the tub must the washing machine or the washing of the Dishwasher corresponding implementation breakthroughs exhibit. If instantaneous water heaters are provided, then they are Piping or tubing required to the Flow heater to integrate in the water cycle.

Handelsübliche keramikgefüllte Polymerschichten sind bis ca. 150°C stabil. Vorzugsweise ist die zu beheizende Fläche außen an einem wasserfüllbaren Behälter des Geräts unterhalb eines regulären Wasserstands vorgesehen. Durch die gut wärmeleitende Verbindung mit der zu beheizenden Fläche bleibt die Heizeinrichtung auf vergleichsweise niedrigen Temperaturen. Zur Solltemperatur des zu erwärmenden Mediums besteht nur eine vergleichsweise kleine Differenz, was zu einem hohen Wirkungsgrad führt.The heating foil creates a large-area heating and is in good thermal conductivity with the connection to heated area. As they are outside of the heated Surface can be attached, it requires no Breakthroughs and no additional piping.
