  • the present invention relates to a washing machine having a drying device, and, more particularly, to a washing machine and suds removal method thereof capable of removing suds, which are excessively generated during a washing cycle, to thereby be introduced into a drying device.
  • a drying device In general, a drying device is designed to supply hot air, heated by a heater, into a drum when the drum is rotated at a low speed, thereby drying wet laundry contained in the drum. As the drying device is combined with a washing machine, the washing machine is able to also be used as a clothes dryer. This type of washing machine has been recently launched in the form of a drum-type washing machine, and serves to independently perform a drying cycle only or to perform a drying cycle after completing washing, rinsing, and dewatering cycles in this sequence.
