Benefits of technology

[0012]Another object of the present disclosure is to provide a washing machine and a control method therefor, the washing machine which implements a new motion that provides excellent washing power compared with a conventional motion applied to a front-loading washing machine.
[0055]In addition, in a state in which laundry is positioned on the drum lower portion, the drum is rotated in one direction. In a state in which a lifter is positioned on the drum lower portion and laundry is positioned on the lifter, the drum is rotated in the opposite direction. Through a process of rotating the drum at the same rotational speed and in different directions, the laundry may fall from a higher position upon rotation in the opposite direction, compared to rotation in one direction. Thus, when the drum is rotated in one direction, relatively greater washing power is applied to the laundry. When the drum 60 is rotated in the opposite direction, a part of the laundry subject to the washing power changes, and thus, washing performance may improve and damage to the laundry may be reduced.

Problems solved by technology

Although the recently developed front-loading washing machine is capable of implementing various motions, a motion with enhanced washing power may cause damage to laundry and a motion causing less damage to the laundry provides insufficient washing power.

first embodiment

[0095]FIG. 4 is a perspective view showing a part of an inner circumferential surface of a drum of a washing machine according to the present disclosure, the washing machine which has a lifter of a height lower than that of a conventional washing machine. FIG. 5(a) is a plan view of a lifter shown in FIG. 4, and FIG. 5(b) is a cross-sectional view of FIG. 5(a) taken away along line I-I′.

[0096]Referring to FIGS. 4 and 5, a lifter 70b made separately from the drum 60 and disposed on the inner circumferential surface of a drum 60 has a height equal to higher than 10 mm and equal to lower than 20 mm. The washing machine according to the first embodiment of the present disclosure includes the lifter 70b of a height lower than that of the conventional lifter 70a in order to implement various motions. The height of the lifter 70b may be between 10 mm and 20 mm. The term “between” refers to a value within a range equal to or higher than a lower limit value and equal to or lower than an uppe...

second embodiment

[0110]As shown in FIGS. 6 and 7, the washing machine according to the present disclosure may include a lifter 70c integrally formed with the drum 60.

[0111]Referring to FIGS. 6 and 7, the inner circumferential surface of the drum 60 may be divided into a lifter portion 67 and an embossed portion 68. In the inner circumferential surface of the drum 60, two or more lifters 67 spaced apart from each other at a predetermined interval along a circumferential direction of the drum may be formed. That is, in a case where three lifter portions 67 are formed in the inner circumferential surface of the drum 60, the lifter portions 67 may be disposed to form an angle of 120° relative to each other. As shown in FIG. 6, in the lifter portions 67, a lifter 70c having a height lower than that of the conventional lifter 70a may be formed integrally with the drum 60.

[0112]In the washing machine according to the second embodiment, the lifter 70c may be formed in each of a plurality of liter portions 6...

Abstract

Disclosed is a control method for a washing machine having three or more lifters inside a drum. The control method includes: positioning the lifters on an outer side of a first area including a drum lower portion, and positioning laundry on the first area; performing a first rotation step to rotate the drum in a first direction so that one of the lifters is positioned on the first area and the laundry is positioned on the lifter positioned on the first area; and performing a second rotation step to rotate the drum in a second direction opposite to the first direction, so that the lifters are positioned on the outer side of the first area and the laundry is positioned on the first area, wherein the first rotation step and the second rotation step are performed alternately and repeatedly.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a National Stage application under 35 U.S.C. § 371 of International Application No. PCT / KR2019 / 011221, filed on Aug. 30, 2019, which claims the benefit of Korean Patent Application No. 10-2018-0103080, filed on Aug. 30, 2018 and Korean Patent Application No. 10-2019-0101925, filed on Aug. 20, 2019. The disclosures of the prior applications are incorporated by reference in their entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present disclosure relates to a washing machine and a control method therefor, and more particularly to a washing machine capable of implementing a new motion and a control method therefor.Related Art[0003]A washing machine is a general term indicating a device for removing a contaminant stuck to clothes, bedding, etc. (hereinafter, referred to as ‘the laundry’) using a chemical disintegration of water and a detergent and a physical operation such as a friction between water and...
