Problems solved by technology

[0013] Moreover, although the feel of the laundry is improved by the untwisting process, if the state of overlapping the laundry continues for a long time due to being left after the end of the washing operation, the effect obtained by the untwisting process is significantly reduced.

Abstract

A drum-type washing machine is provided with: a rotation drum in which items to be washed are accommodated and rotated; an insert opening into which the items to be washed are inserted; a motor for driving the rotation drum; and a control unit for controlling the action of the motor and executing a washing operation having one or more steps selected from among a plurality of steps including washing, rinsing, and draining. The control unit executes a first fabric disentanglement step after completion of the washing operation.

Description

technical field [0001] The present disclosure relates to a drum-type washing machine that puts laundry into a rotary drum and performs washing by performing various steps such as washing and rinsing. Background technique [0002] In conventional drum-type washing machines, a control system has been proposed in which cleaning is performed in a high-concentration state in order to improve cleaning performance (for example, refer to Patent Document 1). [0003] Figure 8 It is a sectional view of the conventional washing machine described in Patent Document 1. [0004] exist Figure 8 In the washing machine shown, laundry is put into rotary drum 101, and the washing machine starts to operate by turning on the power. Then, while water is supplied so that the water level in rotary drum 101 becomes a predetermined water level, rotary drum 101 is driven at a rotation speed N1 (53 r / min). In the washing process of the washing machine, since the laundry absorbs water, rotary drum 1...
