電気洗濯機
Document Type and Number:
Japanese Patent JP5860763
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce nonuniformity in washing and drying.SOLUTION: In an electric washing machine including a rotary vane disk 11 on the bottom of a washing tub, the rotary vane disk includes a plurality of raised parts 11a and valley parts 11b which provide gently inclined surfaces to repeatedly apply an upward component force to laundry on the rotary vane disk by rotation. Each inclined surface formed from the apex of each raised part to the bottom of each valley part has a length in the circumferential direction of the rotary vane disk which is made larger than the difference in height between the apex of each raised part and the bottom of each valley part. The ridge line of each raised part is formed so as to be gradually raised from the center part of the rotary vane disk toward the outer periphery of the rotary vane disk. The ridge line of each raised part and the bottom of each valley part are formed so as to be curved from the center of the rotary vane disk toward the outer periphery of the rotary vane disk in one circumferential direction.
