Problems solved by technology

The center of mass of the three systems is located between the clothes load and the balance ring, and the cylinder as a whole will rotate around the total center of mass, with a large swing angle, which makes it difficult to achieve complete balance of the system, and the vibration is severe
This structure will sacrifice the effective volume of the inner tub, or increase the size of the outer tub to increase the size of the washing machine

Embodiment 1

[0032] This preferred embodiment discloses a washing machine pulsator. Such as figure 1 with figure 2 As shown, the pulsator includes a pulsator body 1 capable of rotating around the connecting shaft hole 11 , four balance cylinders 2 are uniformly arranged on the pulsator body 1 , and each balance cylinder 2 is arranged along the radial direction of the pulsator body 1 . The number of balance cylinders 2 is not limited to four, but can also be two, three, five or other numbers.

[0033] A balance cylinder 2 extending radially along the pulsator body 1 is arranged on the pulsator body 1, so that the center of mass of the washing machine can move to the side of the drive motor, reduce the swing angle of the inner cylinder during rotation, and reduce the amplitude of the inner cylinder, thereby effectively Reduce the overall vibration of the washing machine to ensure that the entire washing machine has better balance and low noise when the inner drum rotates.

[0034] In ord...

Embodiment 2

[0042] This preferred embodiment discloses a washing machine pulsator, the structure of which is basically the same as that of the preferred embodiment 1, except that a balance ring is provided on the outer periphery of the pulsator body instead of a balance cylinder. The pulsator body is closer to the drive motor than the inner cylinder. A balance ring on the pulsator body can make the center of mass of the washing machine move to the side of the drive motor, reduce the swing angle of the inner cylinder during rotation, and reduce the vibration of the inner cylinder, thereby effectively Reduce the overall vibration of the washing machine, and the noise is low.

Embodiment 3

[0044] This preferred embodiment discloses a pulsator for a washing machine, the structure of which is basically the same as that of the preferred embodiment 1, the difference is that, as Image 6 with Figure 7 As shown, in addition to the four balance cylinders 2 provided on the pulsator body 1, a balance ring 3 is also provided on the outer periphery of the pulsator body 1; the structure of the balance ring 3 can be the same as that of the existing balance ring. The simultaneous use of the balance cylinder 2 and the balance ring 3 ensures better balance performance and smaller vibration amplitude of the whole machine.

Abstract

The invention discloses an impeller of a washing machine and the washing machine with the impeller, belongs to the technical field of washing machines and aims at solving the problem of poor damping effect of the existing washing machine. The impeller of the washing machine comprises an impeller body which can rotate around a connection shaft hole, two or more balancing rollers are evenly arranged on the impeller body, and/or a balancing ring is arranged on the periphery of the impeller body; each balancing roller is arranged in the radial direction of the impeller body. The washing machine comprises the impeller. Two or more balancing rollers are evenly arranged on the impeller body of the washing machine, and/or the balancing ring is arranged on the periphery of the impeller body, the balancing rollers and/or the balancing ring can be in linkage with the balancing ring on an inner drum, and the impeller has extremely good deviation rectification effects on real-time mass eccentricity which exists in washing and/or spin-drying of the washing machine and makes the rotation of the inner drum more smooth and steady and the noise lower.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine pulsator and a washing machine including the pulsator. Background technique [0002] The balance ring of the existing washing machine is basically arranged at the opening of the inner cylinder. The balance of the centrifugal force system depends on the balance ring, the laundry load and the rotating inner drum. The center of mass of the three systems is located between the clothing load and the balance ring, and the cylinder as a whole will rotate around the total center of mass, with a large swing angle, making it difficult to achieve complete balance of the system, and the vibration is severe. [0003] In order to improve the balance performance, some washing machines install a balance ring at the bottom of the inner tub. This structure will sacrifice the effective volume of the inner tub, or increase the size of the outer tub to increase the size o...
