Abstract

Official abstract text for this publication.

A washing machine and a method of controlling the washing machine are provided. In the washing machine and the method of controlling the washing machine, a liquid detergent is automatically supplied into a washing tub, thereby improving user convenience. In addition, in the washing machine and the method of controlling the washing machine, a liquid detergent is supplied into the washing tub by water circulated by a circulation unit. Thus, no liquid detergent remains in a liquid detergent supply path, and the liquid detergent supply path can be prevented from being blocked due to the solidification of a liquid detergent.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of controlling a washing machine, the method comprising: opening a water supply valve to supply water from an external water source into a washing tub; and operating a liquid detergent supply pump to supply a liquid detergent from the liquid detergent container into a liquid detergent mixer which is connected to a middle portion of a circulation path; and operating a circulation pump, when the supplying the water and supplying the liquid detergent are completed, to discharge the water from the washing tub to the circulation path and inject the water into the washing tub, wherein the water supply valve is opened and the liquid detergent supply pump is operated at the same time, and wherein the liquid detergent in the liquid detergent mixer is supplied into the washing tub along with the water circulated through the circulation path right after operating the circulation pump. 2. The method of claim 1 , wherein the circulation pump is started to operate when a predetermined amount of liquid detergent is injected into the liquid detergent mixer and a current water level in the washing tub reaches predetermined water level for a circulation operation.
