Samsung patents washing machine that flushes detergent lines with water
This filing describes a washing machine that can clean the internal tubes used to deliver liquid detergent. When a user requests a cleaning cycle, the machine checks if the tube contains water, fills the drum to a specific level, and then pumps that water through the tube to flush out residue.
In the filing’s own words
A washing machine may include a tub; a detergent supply part to accommodate a liquid; a fluid channel connecting the detergent supply part and the tub; a motor controllable to supply the liquid accommodated in the detergent supply part into the tub through the fluid channel; a water supply part controllable to supply water into the tub; and a processor configured to: based on receiving a command for cleaning the fluid channel, identify a type of the liquid accommodated in the detergent supply part, based on the identified type of the liquid being water, control the water supply part to supply water into the tub, detect a level of water in the tub, and based on the detected level being greater than or equal to a predetermined value, control the motor so that the liquid accommodated in the detergent supply part is supplied into the tub through the fluid channel.
