Abstract

Bei gewerblichen Trocknern, bei der die Trocknungsluft von einem Brenner (10) aufgeheizt wird, ist es üblich, die eine Trommel (13) mit der zu trocknenden Wäsche verlassende feuchte Luft (45) als Umluft (47) wiederzuverwenden. Der Anteil der Umluft (47) wird mit zunehmender Trocknung der Wäsche erhöht. Zum Ende des Trocknungsvorgangs, wenn die feuchte Luft (45) nicht mehr so viel Feuchtigkeit wie zu Anfang enthält, werden ein Großteil oder die gesamte feuchte Luft (45) als Umluft (47) verwendet. Dann bekommt der Brenner (10) aber nicht mehr genug Verbrennungsluft, was zu einer unvollkommenen Verbrennung führt.In commercial dryers, in which the drying air is heated by a burner (10), it is customary to reuse a drum (13) with the laundry to be dried leaving moist air (45) as circulating air (47). The proportion of circulating air (47) is increased with increasing drying of the laundry. At the end of the drying process, when the humid air (45) does not contain as much moisture as at the beginning, most or all of the humid air (45) is used as circulating air (47). Then the burner (10) gets but not enough combustion air, resulting in an imperfect combustion.

Die Erfindung sieht es vor, dem Brenner (10) zumindest dann, wenn der Trockner mit einem Großteil oder nur mit Umluft (47) betrieben wird, Frischluft durch einen Ventilator zuzuführen und ihn dadurch praktisch aufzuladen. Dadurch kann der Trockner mit einem höheren Anteil Umluft (47) betrieben werden, wobei gleichwohl durch die Aufladung des Brenners (10) mit Frischluft noch eine optimale Verbrennung gewährleistet ist. Die Erfindung lässt dadurch ein wirtschaftlicheres Trocknen zu.

Figure imgaf001
The invention provides, the burner (10) at least when the dryer is operated with a large part or only with circulating air (47) to supply fresh air through a fan and thereby charge him practically. As a result, the dryer can be operated with a higher proportion of recirculated air (47), while still ensuring optimal combustion by charging the burner (10) with fresh air. The invention thereby allows a more economical drying.
