Problems solved by technology

[0006] However, in a conventional washing machine capable of using liquid detergent, when only a small amount of liquid detergent remains in the liquid detergent container, it may be difficult to pump and supply the remaining amount to the detergent supply device (see, for example, 2010 7 Korean Patent Application Publication No. 10-2010-0081254 published on March 14)
Therefore, the user usually has to load extra liquid detergent that is not actually used in the washing operation

Abstract

The present invention relates to a washing machine including a liquid additive supply device capable of supplying a liquid additive from a storage container even if the liquid level of the remaining liquid additive in the storage container is low. The storage container has a sloped bottom surface. The straw is arranged near or against the lower side of the sloped bottom surface. Due to the sloped bottom surface, the liquid additive tends to collect on the lower side of the bottom surface, and even if only a small amount of liquid additive remains in the storage container, the straw opening can remain below the liquid additive. This advantageously improves the utilization efficiency of the liquid additive loaded in the washing machine by reducing the unusable amount.

Description

technical field [0001] Embodiments of the present invention relate to washing machines, and more particularly to liquid additive supply devices for washing machines. Background technique [0002] A washing machine generally washes clothes or other objects by using friction between water and clothes and emulsification of detergent. Modern automatic washing machines are able to automatically perform washing, rinsing and spinning in an all-in-one process once activated. [0003] Depending on the type of a washing tub for containing laundry, washing machines may be classified into types including a top loading type (in which the washing tub is vertical) and a drum type (in which the washing tub is positioned horizontally). Front load washers typically have a reduced overall height and increased wash capacity and result in less fabric entanglement than top loading washers. Therefore, front-loading washing machines have become more popular. [0004] Washing machines typically h...
