Abstract

The present invention relates to a laundry treating apparatus that smoothly agitates laundry with as large space as possible for receiving laundry. The laundry treating apparatus includes: a rotatable drum that receives laundry, has open front and rear, and is formed to have a non-circular closed cross-section; a rotatable upper circular guide that is disposed with the rotational center higher than the rotational center of the drum and supports a portion having a uniform curvature at the upper portion of the drum; a rotatable lower circular guide that is disposed with the rotational center lower than the rotational center of the drum and supports a portion having a uniform curvature at the lower portion of the drum; and a driving mechanism rotating the drum by rotating the upper circular guide or the lower circular guide.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a rotatable drum that receives laundry, has an open front and an open rear, and is formed to have a non-circular closed cross-section;
a rotatable upper circular guide that is disposed with a rotational center higher than a rotational center of the drum and supports a portion having a uniform curvature at an upper portion of the drum;
a rotatable lower circular guide that is disposed with a rotational center lower than the rotational center of the drum and supports a portion having a uniform curvature at a lower portion of the drum;
a drum guide provided on an edge of the drum to seal a space between the upper and lower circular guides and the drum; and
a driving mechanism directly rotating the upper circular guide or the lower circular guide, wherein a portion of the drum guide which is in contact with the upper circular guide or the lower circular guide is embossed, wherein an outer side of the upper circular guide or the lower circular guide is embossed such that the drum guide does not slip on the upper circular guide or the lower circular guide, and wherein the driving mechanism includes:
a driving wheel connected to the upper circular guide or the lower circular guide via a single rotary shaft;
a motor that generates a rotational force; and
a driving belt that transmits the rotational force from the motor to the driving wheel.

2. The apparatus of claim 1 , wherein the driving mechanism is a motor directly connected to the rotational center of the upper circular guide or the lower circular guide.
