Abstract

Der Wäschetrockner besitzt eine Trommel (1) mit horizontaler Drehachse (20) sowie eine Wärmepumpe mit einem Verdampfer (6) und einem Kondensator (4). Die Prozessluft tritt gegen die Vorderseite (15) des Geräts aus der Trommel (1) aus und wird nach unten geleitet, um sodann in einen Zusatzwärmetauscher (4) einzutreten. Beim Zusatzwärmetauscher (4) handelt es sich um einen Luft-Luft-Wärmetauscher, in welchem die Prozessluft abgekühlt wird. Die Prozessluft tritt nach hinten aus dem Zusatzwärmetauscher (4) aus und wird sodann zur Vorderseite des Geräts und dort zum Verdampfer (6) geführt. Danach gelangt die Luft durch den Kondensator (3), ein Gebläse (10) und eine Zusatzheizung (9) wieder zurück zur Trommel (1). Der Zusatzwärmetauscher (4) wird vorteilhaft unterhalb der Trommel (1) angeordnet.

Figure imgaf001
The tumble dryer has a drum (1) with a horizontal axis of rotation (20) and a heat pump with an evaporator (6) and a condenser (4). The process air exits the front side (15) of the apparatus from the drum (1) and is directed downwardly to then enter an auxiliary heat exchanger (4). The additional heat exchanger (4) is an air-to-air heat exchanger in which the process air is cooled. The process air exits to the rear from the additional heat exchanger (4) and is then led to the front of the unit and there to the evaporator (6). Thereafter, the air passes through the condenser (3), a fan (10) and an additional heater (9) back to the drum (1). The additional heat exchanger (4) is advantageously arranged below the drum (1).
