Abstract

The utility model relates to a washing machine balancing device, namely a washing machine, which comprises a hollow annular shell coaxially arranged on a rotary drum of the washing machine and magnetic rods uniformly distributed in the hollow annular shell, wherein the magnetic poles of the adjacent magnetic rods are the same and can move along the hollow annular shell; the magnetic rods move in the balance ring by utilizing the same polarity repulsion among the magnetic rods, so that the unbalance phenomenon is eliminated.

Description

Washing machine balancing device and washing machine

Technical Field

The utility model relates to a washing machine balancing unit and washing machine.

Background

The washing machine has a tub rotated by a motor, in which laundry is washed and dehydrated. In the dehydration stage, when the rotation speed of the tub is higher than the resonance rotation speed, the laundry is unbalanced due to the unbalance weight so that the dehydration tub is vibrated. Adopt balancing weight and compensating ring two kinds of modes to solve above-mentioned problem among the prior art.

The balancing weight is a heavy part made of cast iron or cement and arranged in the machine body, so that the weight of the whole machine is improved, extra vibration generated when the dewatering barrel is unbalanced is reduced, and the weight of the whole machine is larger in the mode.

The balancing ring is often balanced by the movement of the balancing ball, and the balancing ring is often filled with a balancing liquid having a certain viscosity, such as silicone oil, in order to reduce the friction of the balancing ball, which in turn increases the risk of liquid leakage and thus contamination of the laundry.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model provides a balancing unit is inside to have hollow magnetic rod, thereby utilizes like poles between the magnetic rod to repel each other and makes the magnetic rod take place to remove in the equalizer ring and make uneven phenomenon eliminate.

One or more embodiments provide the following technical solutions:

a balancing device of a washing machine, comprising: a hollow ring-shaped shell coaxially arranged on the rotary drum of the washing machine and a magnetic bar in the shell.

The number of the magnetic rods is at least 8, and the magnetic rods are uniformly distributed along the annular direction of the hollow annular shell.

The magnetic bar is a permanent magnet with a hollow structure.

The adjacent magnetic bars have the same magnetic poles.

The magnetic force bars have certain curvature, and the curvature fits the diameter of the rotary drum of the washing machine and the number of the magnetic force bars.

The hollow annular shell comprises a first shell and a second shell, the first shell comprises a chamber for accommodating the movement of the magnetic rod, and the second shell and the first shell are matched to close the chamber.

The first shell is connected with the rotary drum of the washing machine.

The magnetic bar can move in the chamber under the action of magnetism.

A washing machine comprises a machine body and a rotary barrel, wherein the rotary barrel is provided with the balancing device.

The washing machine provides a washing program, and the washing program comprises a main washing stage, a rinsing stage and a dewatering stage.

The above one or more technical solutions have the following beneficial effects:

1. when the rotary drum of the washing machine is in a static state or a balanced state, the magnetic rods are uniformly distributed in the hollow annular shell by repulsive force between the adjacent magnetic rods.

2. When the rotating barrel of the washing machine is in an unbalanced state, inertia caused by the unbalanced state enables the magnetic rods to be concentrated in the direction opposite to the unbalanced direction to restore the balance, and the repulsive force between the adjacent magnetic rods after the balance is restored enables the magnetic rods to be uniformly distributed in the hollow annular shell again.

3. Liquid does not need to be filled in the balancing ring any more, the rotating barrel is restored to be balanced by utilizing non-contact magnetic repulsive force, collision or friction is avoided, and the liquid leakage problem of the traditional balancing ring is avoided; meanwhile, the rotating barrel does not need a balancing weight any more, so that the space of the rotating barrel is increased, and the weight of the whole machine is reduced.

Drawings

The accompanying drawings, which form a part of the specification, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention without unduly limiting the scope of the invention.

FIG. 1 is a schematic diagram of one or more embodiments of the present invention;

in the figure: 1. magnetic rod, 2, hollow annular shell.

Detailed Description

The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

Example 1:

as shown in figure 1, a balancing device of a washing machine comprises a hollow annular shell 2 coaxially arranged on a rotary drum of the washing machine and a magnetic rod 1 in the shell.

The magnetic force rod 1 is 8 hollow permanent magnets which are circumferentially and uniformly distributed along the hollow annular shell, and the magnetic poles of the adjacent magnetic force rods are the same and can move along the hollow annular shell.

The magnetic force rods 1 have certain curvature, and the curvature fits the diameter of the rotary drum of the washing machine and the number of the magnetic force rods. The larger the diameter of the rotary tub, the larger the number of magnetic bars required, which is given in fig. 1 as 8, but can be 12, 16 or more, depending on the diameter of the rotary tub and the size of the washing capacity. Accordingly, the curvature of each magnetic rod is also obtained according to the diameter of the rotary barrel.

The hollow annular housing 2 comprises a first housing comprising a chamber containing the movement of the magnetic bar and a second housing cooperating with the first housing to enclose the chamber. The first shell is connected with the rotary drum of the washing machine.

When the rotary drum of the washing machine is in a static state or a balanced state, the repulsive force between the adjacent magnetic force rods 1 enables the magnetic force rods 1 to be uniformly distributed in the hollow annular shell 2, and at the moment, the 8 magnetic force rods 1 are in a balanced state.

In the unbalanced state of the rotary tub of the washing machine, as shown in fig. 1, assuming that there are more laundry at the B position, so that the rotary tub of the washing machine is unbalanced in the C direction, the magnetic rods near the C direction will concentrate in the a direction opposite to the unbalance by the rotation of the rotary tub and the inertia generated by the unbalanced state, so as to restore the balance of the rotary tub. With the reduction of clothes or water, the unbalanced state is weakened, and the repulsive force between the adjacent magnetic rods ensures that the magnetic rods are uniformly distributed in the hollow annular shell again to reach the balanced state again.

Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
