Structure of driving unit in drum type washing machine

摘要

A drum type washing machine includes a tub (2) mounted inside a cabinet (1), a drum (3) mounted inside the tub, a shaft (4) connected to the drum mounted inside the tub for transmission of driving force from a motor (5) to the drum, a front bearing and a rear bearing mounted on outer circumferences of the shaft at opposite end portions thereof respectively, a bearing housing (7) built in a central portion of a rear wall of the tub for supporting the front bearing, a motor including a rotor (13) and a stator (14), the rotor being coupled to the rear end portion of the shaft, the stator being fixed to the tub rear wall inward of the rotor. A supporter is fitted between the rear wall of the tub and the stator for supporting the stator and maintaining the concentricity of the stator with respect to the tub. Noise and power consumption are reduced. Product reliability and washing capability are improved, and productivity is increased by improving workability in fabrication of components of the driving unit of the washing machine.
