Short-circuit protected air heater for domestic appliances, in particular for tumble driers

摘要

the present invention relates to a kurzschlusssicherer air heaters (30) for household appliances, such as dryers (3) full of air (40) in a direction of flow (l) durchstru00f6mbar refinement electric heating apparatus (12) with at least one hey izleiter (24), through which the air stream (40) in the operation of erwu00e4rmbar iswith the heizleiter (24) directly with the air stream (40) in contact with a predetermined mindestkontaktabstand next to each other beabstandete (dmin) contact points (26) in which the state of the heizleiters 10 cm (24) different potential concerns and their dire kte electrical connection by a foreign body (20) in air (40) to a circuit.a kurzschlusssicheren water heaters to provide simple design without the constructively elaborate measures to ensure that the foreign body not short in the heating device of heating coil fins can cause erfindungsgemu00e4u00df is providedthat the air flow (40) is in series with the heating device (12) arranged abscheidevorrichtung (1) with durchlu00e4ssen (13) for the air flow (40), whereby the input pathway (13), a durchtrittsgrenzabmessung (27) which, from the abscheidevorrichtung (1) an impenetrable barrier. mdku00f6rper (20) in the airflow (40) with at least one maximum size (1).which is greater than the durchtrittsgrenzabmessung (27), to train with the durchtrittsgrenzabmessung (27) is smaller than the mindestkontaktabstand (dmin).
