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

A washing machine including a liquid additive supply device capable of supplying a liquid additive from a reservoir tank despite a low level of liquid additive left therein. The reservoir tank has an inclined bottom surface. A suction nozzle is disposed proximate to, or adjoins, the lower side of the inclined bottom surface. Due to the inclined bottom surface, the liquid additive tends to gather on its lower side and the suction nozzle opening can remain under the liquid additive even if there is only a small amount left in the reservoir tank. This advantageously improves usage efficiency of the liquid additive loaded in the washing machine by reducing the unusable amount thereof.

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] Washing machines generally wash clothes or other objects by using the friction between water and clothes and the emulsification of detergent. A modern automatic washing machine can automatically perform washing, rinsing, and dehydration in the integrated process once it is started. [0003] Depending on the type of washing tub for accommodating laundry, washing machines may be classified into types including a top-loading type (in which the washing tub is upright) and a drum type (in which the washing tub is positioned horizontally). Compared with the top loading type, the drum type washing machine generally has a reduced overall height and increased washing capacity, and results in less fabric entanglement. Therefore, drum washing machines have become more popular. [0004] The washing m...
