Washing machine with self-cleaning lint filter device and control method thereof

Abstract

The invention discloses a washing machine with a self-cleaning line chip filtering device and a control method of the washing machine. A branch pipeline is led out between a drain opening and a drain valve of the washing machine and is sequentially connected with a circulating pump and the line chip filtering device, the branch pipeline is divided into two branches after passing through the line chip filtering device, the first branch is connected into a washing bucket of the washing machine, and the second branch is connected into a water inlet pipe through a back flushing water inlet valve. Through the circulating pump, washing water in the drain opening in the bottom is led into the line chip filtering device for forced filtration and returns into the washing machine again to form repeated circulation, the washing machine has the advantage of completely filtering line chips out, and filtration is not affected by washing water level; through the corresponding control method, tap water is led in during a washing and / or draining period to flush the line chip filter back, so that the line chips are discharged from the drain opening together with the drained water at the bottom, and the line chip filtering device has the self-cleaning function.
