Abstract

A washing method by a continuous washing machine including a drum having a charge port of a wash at one end and a discharge port thereof at the other end, partitions for dividing the drum into a plurality of chambers, and a scoop for scooping up the wash with the rotation of the drum and sequentially transferring it from a chamber on the side of charge port to a chamber on the side of discharge port, in which the normal rotation of the drum without transfer in the transfer direction and the reverse rotation without transfer are repeated several times to oscillate the wash several times, and then by the reverse rotation of the drum of one complete turn or more, the raising/dropping motion of the wash is performed by the scoop at least once, whereby washing is carried out by the combination of several oscillating motions and at least one raising/dropping motion.

Dependent claims

A washing method for use with a continuous washing machine, the washing machine having a drum with an input end and a discharge end, partitions for dividing the drum into a plurality of chambers, and means for transferring the laundry from each of said plurality of chambers to an adjacent chamber nearer to said discharge end upon rotating said drum in a transfer direction, the method comprising the steps of:

loading laundry into a first chamber at said input end;
crumple washing the laundry by rotating said drum about an axis of rotation through a first angle in said transfer direction without transferring the laundry;
raise and drop washing the laundry by rotating said drum through a second angle in a direction opposite to said transfer direction without transferring the laundry so that the laundry is lifted above the axis of rotation by said means for transferring the laundry and then dropped to a portion of the drum below the axis after the laundry has passed above the axis of rotation of the drum;
and,
transferring the laundry from said first chamber to a second chamber by further rotating said drum through a third angle in said transfer direction.
