VERTICAL TYPE WASHING MACHINE

WIPO Patent Application WO/2023/284711

A1

The present invention provides a vertical type washing machine, capable of improving water saving and washing performance by spraying water to laundry from the upper side. The vertical type washing machine (1) comprises: a washing tub (8), having an outer tub (3) provided with an overflow port (3D) and an inner tub (4) disposed in the outer tub (3); a drainage channel (16), discharging water in the washing tub (8); an overflow channel (21), guiding the water in the washing tub (8) from the overflow port (3D) to the drainage channel (16); a water stop valve (22), opening and closing the overflow channel (21); and a microcomputer (25). The microcomputer (25) performs a tub rotation process in at least one of a washing process and a rinsing process after the washing process. The tub rotation process is: when water is filled in the washing tub (8), the inner tub (4) is rotated, so that the water in the washing tub (8) rises between the outer tub (3) and the inner tub (4) and is sprayed from an outlet/inlet (4D) of the inner tub (4) to laundry (Q) in the inner tub (4). During the rotation of the inner tub (4) in the tub rotation process, the overflow channel (21) is closed by means of the water stop valve (22).
