The invention provides a drum washing
machine which comprises a drum
assembly and a
drying air duct, the
drying air duct is arranged above the drum
assembly, a foam blocking piece is arranged at the
tail end of the
drying air duct, and in the washing state, the foam blocking piece is used for preventing foam in the drum
assembly from entering the drying air duct; a water inlet of the water inlet structure is formed in the side face of the
tail end of the drying
air channel. According to the roller washing
machine, the water inlet of the water inlet structure is formed in the side face of the
tail end of the drying
air channel, so that the water inlet waterway of the
barrel assembly and an air path at the tail end of the drying
air channel are shared, and the space of the drying air path in the roller washing
machine is fully utilized to simplify the water inlet waterway; the
layout of the air path and the water path in the roller washing machine is reasonably planned, and the
miniaturization design of the roller washing machine is facilitated; 2, a foam baffle plate is arranged at the tail end of the drying air duct, and the foam baffle plate can prevent foam in the
barrel assembly from entering the drying air duct in a washing state, so that the foam is prevented from corroding a heating assembly in the drying air duct.
