A drum washing machine includes a driving part which includes a driving motor, a first belt wheel fixed to a rotating shaft of a drum, a second belt wheel fixed to a rotating shaft of a rotating body, a first motor belt wheel fixed to a motor shaft of the driving motor and connected to the first belt wheel via a first transmission belt, a second motor belt wheel connected to the second belt wheel via a second transmission belt, and a clutch mechanism part configured for switching from a first driving form in which the second motor belt wheel is engaged with the clutch mechanism part so that the drum and the rotating body rotate at different speeds driven by the driving motor, and a second driving form in which the motor shaft is disconnected from the second motor belt wheel.

Drum washing machine

A drum washing machine, including: a driving part, capable of operating in a uniaxial driving form and a biaxial driving form; a heater configured to heat water stored in the outer drum for washing; and a control part which at least performs washing operation of a first washing mode and a second washing mode. In a washing process of the first washing mode, the control part enables the driving part to operate in the uniaxial driving form and also enables the heater to operate. Further, in a washing process of the second washing mode, the control part enables the driving part to operate in the biaxial driving form and also enables the heater to operate in such a manner that heat applied to the water is reduced compared with the first washing mode.

A drum washing machine is provided. The drum washing machine includes: an outer tank arranged in a housing; a drum, which is arranged in the outer tank and capable of rotating about a horizontal shaft H; a rotating body, which is arranged at a rear part of the drum, a surface of the rotating body being provided with a projection; and a driving part, configured to drive the drum and the rotating body to coaxially rotate at different rotating speeds. The drum has a baffle arranged on an inner circumferential surface of the drum, which is used as a moving unit configured to move the washings in the drum towards the rotating body. The baffle has gathering surfaces for gathering the washings through a rotation of the drum. The gathering surfaces are inclined so that the side of the rotating body is lagged in a rotation direction of the drum.
