  • Patent number: 10526746
    Abstract: The clothes dryer of the present disclosure includes a circulation air flow path communicating with the drum, a condensed water storage chamber communicating with the circulation air flow path and a pump chamber communicating with the condensed water storage chamber. The communication path introduces air into at least one of the first circulation air flow path and the pump chamber to reduce the pressure of the pump chamber by introducing air into the pump chamber or to introduce air into the condensed water storage chamber through the first circulation air flow path. Accordingly, there is an effect of increasing the air volume of the fan device while preventing backflow and scattering of the condensed water caused by dehumidification in the clothes dryer.
