Abstract

A washing machine with a liquid additive supply device capable of sensing an amount of liquid additive contained therein. A buoyancy body and a sensing unit are disposed in a reservoir tank of the liquid additive supply device. The vertical position and therefore the distance between the buoyancy body and a sensing unit vary with the surface level of liquid additive in the reservoir tank due to buoyancy effect. The buoyancy body may include a magnetic body and the sensing unit can detect the intensity of the magnetic body. The surface level of the liquid additive is too low, the sensing unit can generate a signal indicative of liquid additive shortage.

Description

[0001] Cross References to Related Applications [0002] This application is based on Korean Patent Application No. 10-2016-0017461 filed on February 15, 2016 and claims the priority of this Korean Patent Application, the entire disclosure of this Korean Patent Application is hereby incorporated by reference for all purposes into this article. technical field [0003] Embodiments of the present invention relate to washing machines, and more particularly, to liquid additive supply devices for washing machines. Background technique [0004] A washing machine is generally used to wash clothes or other items by utilizing friction between water and clothes or the like in combination with emulsification of detergent. Modern automatic washing machines are able to automatically perform washing, rinsing and spinning in one complete process once activated. [0005] Depending on the type of washing tub used to hold laundry, washing machines can be classified into top-loading types (i...
