Le sèche-linge selon la présente invention comprend : un trajet de circulation et de ventilation communiquant avec un tambour ; une chambre de réception d'eau condensée raccordée au trajet de circulation et de ventilation ; une chambre de pompe communiquant avec la chambre de réception d'eau condensée ; et un trajet de communication disposée pour réduire la différence de pression entre la chambre de réception d'eau condensée et la chambre de pompe. Le trajet de communication introduit de l'air dans au moins l'un d'un premier trajet de ventilation et la chambre de pompe, et introduit de l'air dans la chambre de pompe de manière à diminuer la pression de la chambre de pompe ou introduit de l'air dans la chambre de réception d'eau condensée par l'intermédiaire du premier trajet de ventilation de manière à augmenter la pression de la chambre de réception d'eau condensée. Par conséquent, le volume d'air d'un dispositif de ventilation est augmenté tandis que le refoulement et la dispersion de l'eau condensée, qui est généré en raison de la déshumidification dans le sèche-linge, sont évités.
