Abstract

Drum type washing machine including a tub fitted in a cabinet, and a pair of drums fitted in the tub to be rotatable in opposite directions, thereby permitting to obtain an excellent washing effect as an entire surface of laundry is made to make uniform friction with the inner drum and the outer drum, and to prevent entangling of the laundry as the laundry is washing during the laundry back and forth the inner drum and the outer drum, alternately.

Description

technical field [0001] The invention relates to a drum-type washing machine, in particular to a drum-type washing machine in which a pair of drums that can rotate in opposite directions are installed in a barrel body for washing. Background technique [0002] Generally, when the drum is rotated by the driving force of the motor and the clothes are put into the drum, the drum type washing machine uses the friction between the drum and the clothes in the specified detergent and washing water to achieve washing. Little to no damage to clothes, very little tangles, and provides a beating and rubbing wash. [0003] 1 schematically shows a cross-section of a prior art drum type washing machine, and FIG. 2 shows an enlarged view of "A" portion in FIG. 1 , and the prior art drum type washing machine will be described below with reference to them. In the following description, the left side of the drawing is the front of the front-loading washing machine, and the right side of the d...
