Embodiment Construction

[0029] figure 1 A laundry drying appliance 1 is shown schematically with a laundry drum 2 which is fluidically connected to a circulation air channel or process air channel 3 . During the drying process, heated process air a is generally blown from the circulating air channel 3 into the laundry drum 2 by means of a circulating air fan (not shown here). There, the process air absorbs the hot moisture with the release of heat and is drawn again from the laundry drum 2 into the circulating air channel 3 and is first refrigerated there for at least partial condensation. In order to cool and condense the process air a cooling body 4 is connected into the circulating air duct 3 , through which cooling body 4 flows the hot and humid exhaust air from the laundry drum 2 . For subsequent heating of the refrigerated process air, a heater 8 is connected into the circulation air channel 3 . After heating, the hot, dry process air is blown onto the laundry drum 2 again.

Abstract

The invention relates to a method for operating a washing/drying device (1), in particular a washing/drying device (1) comprising a washing drum (2), a moisture determining device for determining the moisture content of process air (a) evacuated from the washing drum (2) and a cooling body (4) for cooling the process air (a). Said moisture determining device (9, 10 to 13) comprises at least one temperature sensor (10 to 13) and the at least one temperature sensor (11) is arranged behind an inlet of the cooling body (4) for a medium (a, c) flowing through the cooling body (4) or a medium (c) that is arranged in the cooling body (4).

Description

technical field [0001] The invention relates to a drum with a Moisture determination device (Feuchtigkeitsbestimmungseinrichtung) for moisture content (Feuchtegehalt) of the exhausted (abgeführt) process air (Prozessluft) laundry drying plant And a method for operating such a laundry drying apparatus. Background technique [0002] Laundry drying plants are generally known with a laundry drum, a moisture determination device for determining the moisture content of the process air discharged from the laundry drum, and a cooling body for cooling the process air. Water condensed by the process air is collected in a liquid container or drained through the water outlet. In this context, laundry drying appliances are known which are referred to as condensation dryers and which have a cooling body which is filled with coolant before the laundry drying appliance is put into operation. The coolant here is preferably tap water, which enters the cooling body and is renewed if neces...
