Impeller capable of washing following water-level lifting

Abstract

The invention discloses an impeller capable of lifting and washing along with water level, comprising a wave disc and a plurality of ridgeplates which are arranged on the upper surface of the wave disc, wherein, each ridgeplate comprises a ridgeplate matrix which is arranged on the upper surface of the wave disc; the inside of the ridgeplate matrix is hollow, and an opening is arranged on the upper surface of the ridgeplate matrix; a groove is formed by the opening and the hollow inside; one end in the groove close to the edge of the wave disc is connected with a ridge beam through a rotary shaft or a hinge; one end of the ridge beam close to the wave disc can be lifted up from the opening, and lifting means can be that the ridge beam is supported by a spring which is arranged inside the groove of the ridgeplate matrix and up-vertically connected with the groove and also can be that the ridge beam is floated off under water by a structure and materials of the ridge beam. The structure is automatically arranged on a lifting position when water level is high, and barrier mechanisms are correspondingly arranged on side faces of ridge beams and side faces of grooves in order to increase resistance torsion of water on resisting rotation of the impeller. Moreover, a part of the ridge beams is guaranteed to be always arranged inside the grooves. And the structure is pressed down by the clothes and arranged on a descending position when the water level is low and completely enters into the inside of ridgeplate matrixes, thereby combination of washing and agitator treating is realized.

Description

technical field [0001] The invention relates to a laundry pulsator for a washing machine, in particular to a pulsator that can be raised and lowered for washing with the water level. Background technique [0002] Traditional agitator washing machines use a stirring rod to turn the laundry back and forth during the laundry process to improve the effectiveness of the washing machine for cleaning clothes. The washing machine has a stirring bar arranged in the center of the vertical shaft type inner tub, and the inner tub is rotatably suspended in the outer tub of the washing machine. The stirring rod protrudes upwards from the center of the bottom wall of the inner barrel and generally its height is substantially lower than the height of the inner barrel balance ring. A stir bar generally includes a central column, a base plate and a plurality of blades. During the washing process, the driving mechanism of the washing machine drives the stirring rod to rotate back and forth, ...

Problems solved by technology

[0006] However, the above-mentioned structure has the following disadvantages: 1. The ridge plate head is only connected by a hinge and a spring. When the pulsator rotates, the ridge plate head can deviate from bending due to the force of water, and the hinge is deformed or even separated; Position design, the spring is set on the inner surface of the ridge plate base, water will accumulate on the inner surface after drainage, and bacteria will be generated after a long time; 3. The positioning of the ridge plate head, between the ridge plate head and the ridge plate base When turning, it will fluctuate up and down, which is easy to enter foreign matter or clamp clothes; 4. The lifting distance of the ridge plate head is limited, and the maximum lifting distance pointed out is 0.5 feet, which has limited effect on high water level rinsing and does not solve the problem. proposed question
