washing machine

Abstract

The present invention provides a washing machine capable of improving the cleaning effect when washing the laundry in the washing tub by using the rotation of the washing tub having a longitudinally extending axis and detergent water. The washing machine (1) comprises: a washing tub (4) accommodated in an outer tub 3; a motor (5) for rotating the washing tub (4); a water tank (13) for receiving washings mixed with detergent from the outer tub (3) detergent water; a circulation circuit (11) for drawing detergent water and injecting it into the washing tub (4) from the upper side (Z1); a pump (12) for taking the detergent water in the water tank (13) into circulation The path (11) is raised in the circulation path (11); and the control part (30) executes the washing operation including the dehydration washing process. During the dehydration cleaning process, the cycle treatment, the soaking treatment and the cycle treatment dehydration treatment are repeated, wherein the cycle treatment is to circulate the detergent water in the water tank (13) between the washing tub (4) and the circulation path (11) and Pour it to the laundry (Q) in the washing tub (4); soaking treatment is to make the detergent water soak the washing (Q) in the washing tub (4) after the circulation treatment and return it to the water tank (13); dehydration treatment Dehydration of the laundry (Q) is performed by rotating the washing tub (4) after the soaking treatment.

Description

technical field [0001] The present invention relates to washing machines. Background technique [0002] In the drum-type washing machine described in Patent Document 1 below, a beating washing process and a squeeze washing process after the beating washing process are performed during the washing process. During the beating washing process, the forward rotation, reverse rotation and pause of the drum-shaped rotating drum provided in the water tub are repeated, so that the action of lifting and dropping the laundry in the drum-shaped rotating drum is repeated. In the squeeze washing process, by rotating the drum-shaped washing drum at a higher speed than in the beating washing process, the laundry is thrown to the inner surface of the drum-shaped washing drum due to centrifugal force, and the washing liquid in the laundry The small holes passing through the peripheral surface of the drum-shaped washing drum are extruded out of the drum-shaped washing drum. The drum type was...

Problems solved by technology

In particular, unlike the drum-type washing machine in Patent Document 1, for a vertical washing machine having a washing tub with a longitudinally extending axis, since detergent water tends to accumulate on the bottom side in the washing tub, there is water in the washing tub. Only the lower part of the laundry is impregnated with detergent water

Therefore, it is difficult to realize the improvement of the cleaning effect by detergent water
