Abstract
A small size pulsator-type automatic washing machine comprises a housing, a control panel seat mounted on the top of the housing, a pedestal mounted at the bottom of the housing, an outer tub and an inner tub mounted inside the housing. A direct driving motor and a bearing block are mounted at the bottom of the outer tub. The motor is mounted on the outer tub by fixing elements, and a motor shaft is coupled with a pulsator shaft inside the bearing block. A fastener strap fixes the motor and the bearing block together onto the outer tub of the washing machine, thus reducing occupied space of the washing machine while improving a variety of installation mechanism of conventional washing machine. An insulation unit is disposed in the joint between the motor shaft and the tub shaft, such that the two parts cannot be in direct contact.
