Washing machine and washing method

Abstract

The invention discloses a washing machine and a washing method. The washing machine comprises a wash bucket and an impeller on the bottom of the wash bucket. The impeller comprises a rotary plate and a plurality of water-stirring blades arranged on the surface of the rotary plate, the rotary plate is a discoid structure with a ridgy center, each water-stirring blade extends from the ridgy center of the rotary plate to the edge of the rotary plate, the inner wall of the wash bucket is provided with a plurality of strip-shaped protruding ribs which are vertically arranged, a certain distance is left between the external periphery of the impeller and the bottom edge of the inner wall of the wash bucket, a bucket bottom outer ring is arranged between the external periphery of the impeller and the bottom edge of the inner wall of the wash bucket, and the joint of the bucket bottom outer ring and the inner wall of the wash bucket is provided with a plurality of projections which protrude from the bucket bottom outer ring and the inner wall of the wash bucket in the circumferential direction. With respect to the washing machine, washing water is saved, the concentration of the washing agent is increased, the up-down overturn speed is increased, the cleaning ratio is increased, the cleaning uniformity is improved, washing time is reduced, and clothes winding phenomena are reduced, after being washed, clothes are distributed uniformly in the bucket, and subsequent stable dehydration is facilitated.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine and a washing method which save washing water, evenly turn over and prevent clothes from being entangled. Background technique [0002] At present, the washing method of the pulsator washing machine is to turn the laundry through the special water flow formed by the rotation of the pulsator or the simultaneous rotation of the pulsator and the inner tub, and apply force to it during the turning process, so that it can rub against itself and interact with the wave. The friction between the wheel and the wall of the inner barrel, repeated washing to achieve the purpose of cleaning. The shape of the pulsator in the pulsator washing machine is ever-changing, such as dish-shaped pulsator, rod-shaped pulsator, bowl-shaped pulsator, etc., but no matter how the shape of the pulsator changes, its ultimate purpose is to improve the washing effect without exception.

Problems solved by technology

[0003] In order to improve the cleanliness, it is necessary for the pulsator to rotate at a large angle and rotate at a fast speed during washing. The water flow under the centrifugal force drives the laundry to move in one direction at high speed, but eventually the laundry will be entangled and the laundry will be torn. The pull is damaged, especially high-end clothes, which are more likely to be damaged; moreover, the washing process relies solely on the action of water flow, the movement form is single and fixed, and the turning efficiency of the laundry in the inner bucket is low, and more washings are required to complete Washing effect on the entire laundry

[0004] In addition, when this type of washing machine is running, the pulsator rotates or swings to form a circular water flow. Since the movement of the clothes in the washing tub depends on fluid motion or fluid power, in order to achieve the required circular turning mode, it is also necessary to Filling an automatic washing machine with a bottom pulsator with washing liquid in which the height of the washing liquid added to the washing tub must be sufficient to completely submerge the fabrics loaded into the washing drum consumes a large amount of water, in addition, due to The amount of water is large. In order to achieve a sufficient concentration of detergent, the amount of detergent must be increased. The cost of washing is high, and it also causes certain pollution to water resources.

[0005] Ordinary pulsator-type washing machines move clothes alternately clockwise and counterclockwise under the drive of the pulsator, and improve the washing effect through the friction between clothes and between clothes and water, because the strong water flow brings The disadvantage is that the winding is relatively large, the washing is uneven, and the water is wasted

Dual-power washing machines use the pulsator and the inner tub to rotate in reverse to increase the friction between the clothes, water and the inner tub and improve the washing effect. However, due to the shape of the pulsator, the washing water flow is similar to that of an ordinary pulsator washing machine. Anti-alternating movement, although the cleaning effect is improved, but the winding problem is still limited

Ordinary dual-power pulsators are usually basin-shaped large pulsators. This type of pulsator is similar to a basin-shaped, with a concave in the middle. If you want to turn the clothes over, you must have a strong water flow to drive the water and clothes to turn over, and the clothes are easy to tangle up. together
