technical field

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

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.

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 of the washing machine.

In particular, the pulsator body is formed with a paddle that protrudes toward the front, and the balance cylinder is arranged in a groove on the back of the paddle.

In particular, the balance cylinder is a cavity structure, and the cavity structure is filled with fluid.

Further, the fluid is salt water or silicone oil doped with solid blocks; the volume of the fluid is 2/3 of the internal volume of the balance cylinder.

In particular, the cavity structure is filled with fluid and a sliding block, and the sliding block can reciprocate and slide along the axial direction of the balance cylinder under the lubrication of the fluid.

In particular, an elastic device is further provided in the cavity structure, and one end of the elastic device abuts against the inner end of the cavity structure, and the other end abuts against the sliding block.

In particular, the balance cylinder is arranged horizontally or obliquely relative to the pulsator body.

In particular, the balance cylinder has a columnar structure or a curved structure; the cross section of the balance cylinder is circular, elliptical, rectangular, rhombus, triangular or pentagonal.

On the other hand, the present invention adopts the following technical solutions:

A washing machine comprises the above washing machine pulsator.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

Preferred embodiment one:

This preferred embodiment discloses a washing machine pulsator. As shown in Figures 1 and 2, the pulsator includes a pulsator body 1 that can rotate 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 pulsator body. 1 radial setting. The number of balance cylinders 2 is not limited to four, but can also be two, three, five or other numbers.

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.

In order to ensure that the effective volume of the inner cylinder is not compressed and the size of the outer cylinder is not increased after adding the balance cylinder 2, a paddle 12 protruding to the front is formed on the pulsator body 1, and the balance cylinder 2 is arranged in the groove on the back of the paddle 12 Inside, that is to ensure that the thickness of the existing pulsator does not increase (or does not significantly increase), thereby ensuring that the size of the washing machine does not increase. When there are four shifting blades 12, two or four balance cylinders can be provided; when there are two balance cylinders 2, the connecting line of the two balance cylinders 2 passes through the connecting shaft hole 11.

The specific structure of the balance cylinder 2 is not limited. Preferably, as shown in FIG. 3 , the balance cylinder 2 has a cavity structure filled with a fluid 21 . The fluid 21 can flow, and when the clothes are uneven during the washing or dehydrating process, the position of the fluid 21 in the balance cylinder 2 will change (near the center of the pulsator body 1 or near the outer edge of the pulsator body 1), which can supplement weight and balance.

The fluid 21 can be salt water or silicone oil doped with solid blocks (shape, volume, and material are not limited), or other substances, as long as they can be filled in the cavity structure and have fluidity. The volume of the fluid 21 is 2/3 of the internal volume of the balance cylinder 2, and the remaining 1/3 space is left for the fluid 21 to flow freely.

On the basis of the above structure, as shown in FIG. 4 , one or more sliding blocks 22 can also be placed in the balance cylinder 2 , and the sliding blocks 22 can slide back and forth along the axial direction of the balance cylinder 2 under the lubrication of the fluid 21 . Preferably, the outer diameter of the sliding block 22 is slightly smaller than the inner diameter of the balance cylinder 2, and the length is less than 1/3 of the length of the balance cylinder 2, so that the sliding block 22 can change its position in the balance cylinder 2 according to the balance of the inner cylinder , to automatically compensate for the eccentricity of the laundry load.

On the basis of the above structure, a shock absorber 23 may be provided on the upper end and/or lower end of the sliding block 22 to prevent the sliding block 22 from moving and colliding in the balance cylinder 2 to generate noise.

On the basis of the above structure, as shown in Figure 5, in the cavity structure, an elastic device 24 can also be provided on one side or both sides of the sliding block 22, one end of the elastic device 24 abuts against the inner end of the cavity structure, and the other One end abuts on the sliding block 22 . The elastic device 24 enables the sliding block 22 to be positioned at a certain position in the balance cylinder 2 more accurately according to the magnitude of the load eccentricity, and can quickly return to its position after washing and/or dehydration is completed.

The spatial form of the balance cylinder 2 is not limited, and the balance cylinder 2 can be installed horizontally or inclined relative to the pulsator body 1; the overall balance cylinder 2 can be in a columnar structure or a curved structure (such as S-shaped); the cross-section of the balance cylinder 2 is Circular, oval, rectangular, rhombus, triangular or pentagonal; the size of the balance cylinder 2 can be determined according to the size of the pulsator body 1 .

This preferred embodiment discloses a washing machine pulsator, the structure of which is basically the same as that of the preferred embodiment 1, the difference is that, as shown in Figure 6 and Figure 7, the pulsator body 1 is provided with four balance cylinders 2 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.

Preferred embodiment four:

The preferred embodiment discloses a washing machine. As shown in FIG. 8 , the washing machine includes various washing machine pulsators as described in the first or second preferred embodiment. A balance tube 2 is arranged on the pulsator body 1 of the washing machine, so that the center of mass of the washing machine can move to the side of the drive motor, reduce the swing angle when the inner tube rotates, reduce the vibration of the inner tube, and then effectively reduce the overall vibration of the washing machine, ensuring When the inner drum rotates, the whole washing machine has better balance and low noise.
