A particularly simple control of the 5 collecting container. 2 is initially a heder ft drying cycle in Abhängickeit from that in the collecting and for further increasing the Benalterstands tu container located Kondensatmenae inventions is useful as measured by a Feuer7 wherein reaches the Iedungsgemäß characterized as "the condensate to the 6, 7 as Supports of the balance beam are configured to have a quantity weighing device with a shift gate. The filling amount is determined in the Aiislurmingsriebeispiel, by means of which the dryer io is transferred to the housing-fixed switches 9, 10 through a switch arranged on the collecting container 2 in the course of a sound control device over which the ^ n device can be operated. The drainage pipe 3 connected to the capacitor outlet is preferably filled so that the condensate collecting container is filled so that the balance base 4 lowers. stint that in the course of the displacement path of the position .5 and the pawl 8 first actuates the switch 9 correctly inserted into the dryer housing and then further lowering the densat collecting container the dryer control upstream switch 0. The switch «» delivers z. B. a direction is switchable. The collecting container closes when the collecting container is emptied. If the correct position is used in the dryer housing, the switch 10 delivers a signal as long as em max - is not signaled to the dryer control device via a bridged contact and also the Auffangbeha, the shifting gate with deflated Auffangbehäl- ter 2 provides located in the proper inserted position, (he a dry the additional / wide Feder7 for supporting <\ c program or blocks a signal to enable the start at a Minimum filling balance: ..- lkens causes.

No. 2 742 7 (IK). However, since the condensate collecting container is often not emptied in good time, there is a risk of overflowing. In another context, there are level measuring devices for containers in the form of Floats, electrodes, pressure monitors, level sensors for monitoring tank filling. / R, etc. known (German utility model C: I 863 375), but these have the disadvantage that for Emptying the container in each case separating parts zvvi see the container and the level measuring or dv .; Füllstandsanzeigevorrichiung are necessary. Such Füllstundsmeßeinrichtungen are relatively expensive, have low operational reliability and were therefore used to monitor the collecting container in tumble dryers can only be used with disadvantages. The invention is based on the object of providing a ,, tumble dryer mi? in dry air stream arranged condensation device as well as a con condensate-collecting container to create, which has a simple and reliable means dl · .. · monitoring the level assumes automatically and incorrect operation of the dryer, which would lead to an overflow of the collection container avoids. According to the invention this is achieved in that a condensate volume measuring device on the collecting container Direction is attached, by means of which the dryer control device is switchable. This will make the The amount of condensate and the fill volume are monitored automatically automatically used to control the actual drying cycle, such that on the one hand an overfilling of the condensate collecting container or a control signal.
