Abstract (en)
A dryer 1 comprising a drum 2 and a process air circuit 3 including a blower 12 ; a condensing device 18; a condensate collecting vessel 5; a condensate tank 6; an overflow container 8; an electric pump unit 7; a pump conduit 9 fluidly connecting a pump outlet 35 to a condensate tank inlet 36; an overflow conduit 10 fluidly connecting the overflow container 8 to the condensate collecting vessel 5. The pump conduit 9 comprises at a bypass conduit entry point 31 a flap system 25 including a flap 27 allowing a flow of condensate 22 from the pump outlet 35 to pass directly to the condensate tank 6 in that the bypass conduit 26 is closed by the flap 27, and to allow a flow of condensate 22 into the bypass conduit 26 and an overflow siphon 24 when the flow direction has changed.
