Wherein, the hanging seat and the shock absorption seat are respectively provided with a through hole with the diameter larger than that of the hanging rod part 1, the hanging rod part 1 penetrates through the hanging seat and the shock absorption seat, and the top mounting seat 6 and the positioning part 21 are respectively positioned at the outer sides of the hanging seat and the shock absorption seat, thereby respectively attaching to the hanging seat and the shock absorption seat under the action of gravity of the outer cylinder.
The upper part of the sleeve 2 may be a tapered annulus 22 of upwardly tapering diameter, the tapered annulus 22 being connected to the top mount 6 by an arcuate connecting portion 23. The arc-shaped connecting portion 23 may be attached to the damper base at a lower portion of the positioning portion 21.
The bottom of the sleeve 2 may be provided with a rear cover plate 24 to define a receiving chamber together with the sleeve 2. The bottom end of the boom portion 1 is preferably in the receiving cavity. In an alternative embodiment, the bottom end of the boom portion 1 may also extend from the back cover plate 24 out of its interior receiving cavity.
In particular, the adjustable damping boom 10 further comprises: a first magnetic part 3 provided to the boom portion 1 and a second magnetic part 5 provided to the sleeve 2, wherein the first magnetic part 3 and the second magnetic part 5 are arranged to be spaced apart and such that a mutual magnetic force therebetween is variable in accordance with a relative movement displacement between the sleeve 2 and the boom portion 1 in the axial direction.
The adjustable damping boom 10 of the present invention is configured such that a first magnetic member 3 is provided on the boom portion 1, a second magnetic member 5 is provided on the socket 2 at a distance from the first magnetic member 3, and the first magnetic member 3 and the second magnetic member 5 are arranged such that mutual magnetic force therebetween is variable in accordance with relative movement displacement between the socket 2 and the boom portion 1 in the axial direction. The magnitude and/or polarity of the mutual magnetic force between the first magnetic part 3 and the second magnetic part 5 can be controlled according to the relative movement displacement between the sleeve 2 and the suspender part 1 along the axial direction, so that the first magnetic part 3 acts on the second magnetic part 5 with an acting force with the magnitude corresponding to the distance between the first magnetic part and the second magnetic part and/or an acting force opposite to the axial movement direction of the sleeve 2; thereby, the damping force of the adjustable damping boom 10 can be adjusted by reducing the amplitude of the reciprocal movement of the sleeve 2 by using the magnetic force.
In a preferred embodiment, the magnitude and polarity of the magnetic force is variable with relative movement displacement between the sleeve 2 and the boom portion 1 in the axial direction. In such an embodiment, when the sleeve 2 is in the initial position with respect to the hanger part 1, the magnitude and direction of the mutual magnetic force between the first magnetic part 3 and the second magnetic part 5 are determined (the magnitude of the magnetic force may also be 0); when the second magnetic member 5 is apart from the first magnetic member 3 with respect to the initial position along the axial direction with the sleeve 2, the mutual magnetic force between the first magnetic member 3 and the second magnetic member 5 is a magnetic attractive force; when the second magnetic part 5 approaches the first magnetic part 3 with the sleeve 2 in the axial direction with respect to the initial position, the mutual magnetic force between the first magnetic part 3 and the second magnetic part 5 is a magnetic repulsive force. The magnitude of the magnetic attraction force and the magnetic repulsion force may vary with the relative distance between the first magnetic part 3 and the second magnetic part 5.
In some embodiments, the first magnetic part 3 is a permanent magnet; and the second magnetic part 5 is an electromagnetic coil.

The position of the electromagnetic coil relative to the permanent magnet and the movement direction of the electromagnetic coil are calculated, and the direction and the size of the current of the electromagnetic coil are controlled, so that the permanent magnet always provides an acting force opposite to the movement direction of the sleeve 2 to the electromagnetic coil, and the damping force is exerted.
In some embodiments, the first magnetic member 3 is fixed to the bottom end of the boom portion 1 inside the sleeve 2, and the second magnetic member 5 is fixedly disposed on the bottom wall or back cover plate 24 of the sleeve 2. The radial dimension of the first magnetic member 3 should be larger than the dimension of the central through hole of the positioning portion 21 to prevent the bush 2 from being detached from the tip of the boom portion 1.

In some embodiments, the elastic element 4 is a compression spring; and the elastic element is sleeved on the hanging rod part 1 between the top wall of the sleeve 2 and the first magnetic part 3. In the illustrated embodiment, a flange extends from the bottom end of the first magnetic member 3 in a radially outward direction, and the compression spring 4 is sleeved on the suspension rod portion 1 between the top wall of the sleeve 2 and the flange of the first magnetic member 3.

In an alternative embodiment, the first magnetic part 3 is an electromagnetic coil, the second magnetic part 5 is a permanent magnet; or both the first magnetic member 3 and the second magnetic member 5 are electromagnetic coils.
In an alternative embodiment, the elastic element 4 may also be a torsion spring; one end of the rod is fixed on the inner wall of the sleeve 2, and the other end is fixed with the suspender part 1.
As can be seen from the above description of the structure of the adjustable damping hanger 10 of the present invention, the adjustable damping hanger 10 of the present invention is particularly suitable for being applied in a pulsator washing machine to support the tub of the pulsator washing machine in a suspended state within the housing thereof. When the outer cylinder vibrates, the amplitude of the reciprocating motion of the sleeve 2 is reduced through the magnetic force between the first magnetic part 3 and the second magnetic part 5, so that the vibration of the outer cylinder is reduced. Therefore, the invention also provides the pulsator washing machine.
Fig. 3 is a schematic structural view of the pulsator washing machine 100 according to an embodiment of the present invention. As shown in fig. 3, the pulsator washing machine 100 according to the embodiment of the present invention includes a plurality of adjustable damping suspenders 10 as in any one of the previous embodiments, a housing 110, an outer tub 120 disposed inside the housing 110, an inner tub 130 rotatably disposed in the outer tub 120, and a rotation mechanism 800 for driving the inner tub 130 to rotate.
Fig. 4 is a schematic structural view of the outer tub in the pulsator washing machine 100 shown in fig. 3. The top of the housing 110 has a plurality of hangers 111 distributed thereon that mate with the top mounts 6 of the adjustable damping boom 10. The outer cylinder 120 is disposed in the housing 110, and a plurality of shock-absorbing seats 121 matched with the positioning portions 21 of the adjustable damping hanger rods 10 are distributed on the circumferential wall of the lower portion of the outer cylinder 120, and the top mounting seats 6 and the positioning portions 21 of the plurality of adjustable damping hanger rods 10 are respectively connected with the plurality of hanging seats 111 of the housing 110 and the plurality of shock-absorbing seats 121 of the outer cylinder 120, so as to hang the outer cylinder 120 in the housing 110.
In the preferred embodiment, the washing tub formed by the inner tub 130 and the outer tub 120 is suspended by 4 adjustable damping booms 10, and the angle of the horizontal projection of the adjacent adjustable damping booms 10 is 90 degrees. That is, the 4 adjustable damping hanger rods 10 are uniformly and radially distributed along the circumference of the outer cylinder 120, so that the 4 adjustable damping hanger rods 10 are uniformly stressed.
In some embodiments of the present invention, the rotating mechanism 800 may include a driving motor, a transmission mechanism having a planetary gear and a sun gear, and the driving motor drives the inner barrel 130 and the pulsator in the inner barrel 130 to rotate in the same or opposite directions through the transmission mechanism.
When the outer drum of the pulsator washing machine 100 vibrates in the radial direction, the sleeve 2 reciprocates in the axial direction of the hanger rod part 1, so that the relative displacement between the permanent magnet and the electromagnetic coil in the axial direction changes. In some embodiments, a sensor (not shown) may be disposed on the outer cylinder to detect the vibration of the outer cylinder to calculate the relative displacement of the permanent magnet and the solenoid coil in the adjustable damping boom 10 along the axial direction, so as to supply a corresponding current to the solenoid coil of the adjustable damping boom 10. In some embodiments, the current to the solenoid of the adjustable damping boom 10 may also be controlled based on the speed signal fed back from the drive motor to produce a matched damping force. In an alternative embodiment, the relative displacement of the sleeve 2 in the axial direction of the boom portion 1 can also be detected by means of a sensor, supplying a corresponding current to the solenoid of the adjustable damping boom 10. Therefore, the damping can be adjusted in real time by utilizing the magnitude and the direction of the magnetic force between the electromagnetic coil and the permanent magnet.
In a further embodiment, with continued reference to fig. 3, the washing machine 100 further includes a first permanent magnet 510 and a second permanent magnet 520. The first permanent magnet 510 is arranged outside the bottom wall of the inner cylinder 130; the second permanent magnet 520 is disposed inside the bottom wall of the outer tub 120 and opposite to the first permanent magnet 510. The opposite surfaces of the second permanent magnet 520 and the first permanent magnet 510 have the same magnetism to support the inner cylinder 130 in the outer cylinder 120 using the magnetic repulsive force between the second permanent magnet 520 and the first permanent magnet 510. That is, the first permanent magnet 510 is suspended above the second permanent magnet 520 by virtue of the magnetic repulsion between the first permanent magnet 510 and the second permanent magnet 520, and under the action of the magnetic repulsion between the first permanent magnet 510 and the second permanent magnet 520, the first permanent magnet 510 can generate an upward supporting force on the inner cylinder 130 through the bottom wall of the inner cylinder, so that the inner cylinder 130 is suspended and supported in the outer cylinder 120 by overcoming the gravity of the inner cylinder 130 and the gravity of the content of the inner cylinder, and thus the inner cylinder 130 is not in contact with the outer cylinder 120 when rotating, and the mechanical friction between the inner cylinder 130 and the outer cylinder 120 is avoided, thereby effectively achieving the effects of vibration reduction and noise reduction. Wherein the weight of the inner cylinder 130 itself and the weight of its contents can directly act on the bottom wall of the outer cylinder through the first and second permanent magnets 510 and 520. The above washing machine 100 may also be referred to as a magnetic levitation washing machine.
The invention reduces the radial vibration amplitude of the outer cylinder 120 (or buffers the radial vibration of the outer cylinder 120) through the magnetic force between the first magnetic part 3 and the second magnetic part 5 of the adjustable damping suspender 10; by directly or indirectly disposing the first and second permanent magnets 510 and 520 (hereinafter, simply referred to as up-down magnets) on the inner and outer cylinders 130 and 120, respectively, a supporting force is provided to the inner cylinder 130 by virtue of a repulsive force between the up-down magnets.
The inventors of the present invention have found that, in the case of the magnetic levitation washing machine, since the inner cylinder 130 is suspended above the outer cylinder 120 by means of the repulsive force between the upper and lower magnets, the inner cylinder 130 loses radial constraint when rotating at a high speed, and thus radial wobbling is easily generated.
By arranging the adjustable damping hanger rod 10, the invention can relieve the radial vibration of the outer cylinder 120 and further relieve the radial vibration of the inner cylinder 130. It will be seen from this that the adjustable damping boom 10 of the present invention is particularly well suited for use in magnetic levitation washing machines. According to the invention, the upper and lower magnets and the adjustable damping suspender 10 are combined to form an organic whole, so that axial vibration buffering and radial vibration restraint can be realized, and unexpected excellent damping effect is achieved. Those skilled in the art will appreciate that the solution of using the adjustable damping boom 10 to reduce the amplitude of the radial vibration of the tub 120 is not only applicable to magnetic levitation washing machines, but also to other vertical washing machines, such as conventional bearing driven washing machines.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
