Abstract

A method of controlling a washing machine includes detecting a water level in a drum when a barrel cleaning is executed; supplying or draining water according to the detected water level such that a water level reaches a reference water level; soaking an interior of the drum in water; draining water after the interior of the drum is soaked in water; and detecting clothes contained in the drum by rotating the drum.

First claim

What is claimed is:

1. A method of controlling a washing machine when a barrel cleaning is selected, the method comprising:
determining whether an object exists in a drum of the washing machine;
based on determining that an object does not exist in the drum, performing the barrel cleaning by:
supplying water into a tub of the washing machine,
heating water contained in the tub, and
rotating the drum; and

based on determining that an object exists in the drum, indicating that the barrel cleaning is not to be performed.

2. The method as claimed in claim 1 , wherein the determining is based on inertia of the drum.

3. The method as claimed in claim 1 , further comprising:
supplying water into the drum;
draining water out of the drum; and
rotating the drum from a first rpm to a second rpm greater than the first rpm,
wherein the determining is based on a power used to rotate the drum from the first rpm to the second rpm.

4. The method as claimed in claim 1 , further comprising:
supplying water into the drum;
draining water out of the drum; and
rotating the drum from a first rpm to a second rpm greater than the first rpm,
wherein the determining is based on a time taken to rotate the drum from the first rpm to the second rpm.
