Problems solved by technology

[0010] The modular fluid dispensing system of prior document 2 also has the problem of requiring multiple pumps to supply multiple fluids to washing machines etc.
[0012] However, there is a problem that detergent can be selectively extracted from only two detergent tanks, as disclosed in existing document 3 by a motor. The gear pump control method can draw detergent from one or two boxes, and multiple motors and gear pumps must be set up to extract detergent from three or more boxes

Abstract

The present disclosure relates to a washing machine. The washing machine has a detergent supply device including: a plurality of cartridges containing the additive respectively; a plurality of check valve assemblies connected to the plurality of cartridges to control extracting of the additive, and having a space in which the extracted additive is temporarily stored; a pump which extracts the additive; an inlet channel having a plurality of flow paths respectively connected to the plurality of check valve assemblies, and transmitting a pressure change generated from the pump to the space of the plurality of check valve assemblies; and a flow path switching valve connected to the pump and the inlet channel, and selectively communicating the pump with any one of a plurality of flow paths ofthe inlet channel, so that the additives stored in a plurality of cartridges can be supplied by using a single pump.

Description

technical field [0001] The present disclosure relates to a washing machine, and more particularly, to a washing machine capable of automatically supplying various types of detergents. Background technique [0002] A washing machine is a device that processes clothes through various actions such as washing, spinning and / or drying. A washing machine is an apparatus that removes pollutants from laundry (herein, also referred to as 'clothes') by using water and detergent. [0003] Recently, there has been an increasing demand for an automatic detergent supply device that automatically mixes and supplies various types of detergents to suit clothes, and related technologies are being actively developed. [0004] Patent Publication No. 10-2013-0062271 (hereinafter also referred to as "Prior Document 1") relates to a dispensing system for supplying detergent to home appliances such as washing machines, and discloses multiple reservoirs, and fluid lines leading to detergent contain...
