Description
Technical Field
The invention relates to a damping device, in particular to an adjustable damping suspender for a pulsator washing machine and the pulsator washing machine with the same.
Background
As is well known, in the operation of a washing machine, vibration cannot be avoided due to unbalance loading and centrifugal force of the washing articles. The damping device generally adopted by the current pulsator washing machine is an adjustable damping suspension rod which is connected with the shell of the washing machine and the washing outer cylinder, and sliding friction is formed mainly through the up-and-down movement of a friction part on the adjustable damping suspension rod to generate friction force so as to play a damping role. The disadvantage of this construction is that the resulting friction is almost constant regardless of the laundry, and no variation or adjustment of the damping is possible.
The magnetic rheological liquid is an intelligent material with wide application and excellent performance. When no magnetic field exists around, the magnetorheological fluid shows good liquid fluidity; when a strong magnetic field exists around the magnetorheological fluid, the viscosity of the magnetorheological fluid is rapidly increased in a short time, and the morphological characteristics of a solid are shown; and the change is reversible, namely when the surrounding environment is recovered to a magnetic field-free state, the magnetorheological fluid is recovered to the original liquid flowing state. Due to its special properties, many prior art shock absorbers contain magnetorheological fluids.
In the prior art, a damper based on magnetorheological fluid (referred to as a magnetorheological damper for short) generally comprises a cylinder body containing the magnetorheological fluid, a piston arranged in the cylinder body, and a piston rod with one end fixedly connected with the piston and the other end extending to the outside of the cylinder body, wherein a coil and a fluid channel are arranged on the piston, and the fluidity of the magnetorheological fluid in the fluid channel is changed by changing the current in the coil, so that the damping is changed.
The magneto-rheological shock absorber can play a role in adjusting damping by changing the magnitude of current for providing the coil. Therefore, the shock-absorbing material has very promising application prospect in the technical field of shock absorption. At present, washing machine manufacturers apply the magnetorheological damper to the drum washing machine.
Disclosure of Invention
For the pulsator washing machine, due to its own structural features, the vibration source is usually located at the bottom of the washing tub, and in order to perform the supporting and damping functions, the damper needs to be installed obliquely, one end of the damper is installed at the top of the pulsator washing machine housing, and the other end of the damper is installed at the lower part (close to the bottom) of the washing tub, so that the length of the damper is required to be long, and such damper is usually in the form of a hanger rod.
For the magnetorheological damper with the structure, if the magnetorheological damper is applied to the pulsator washing machine, the length of the piston rod of the magnetorheological damper needs to be prolonged more so as to form a hanging rod. However, it is generally considered by those skilled in the art that if the piston rod is too long, when the magnetic field is increased to increase the viscosity of the magnetorheological fluid, the resistance to the reciprocating motion of the piston rod will be increased, and the piston rod is easily deformed or even bent. Therefore, the magnetorheological damper is not made into a hanger rod by the technical personnel in the field and is used in the pulsator washing machine, so that the magnetorheological damper suitable for the pulsator washing machine is not available in the prior art.
The inventor creatively manufactures the magneto-rheological damper in the form of the suspension rod, and the inventor finds that the magneto-rheological damper in the form of the suspension rod can have better damping effect than the existing suspension rod damper when being applied to the pulsator washing machine through a large number of experiments. Research on the bearing and amplitude of the washing outer cylinder of the pulsator washing machine shows that when the magnetorheological damper in the form of the suspension rod is applied to the pulsator washing machine, a large magnetic field is not required to be applied to enable the viscosity of the magnetorheological fluid to be large, and therefore the piston rod cannot be bent during movement.
However, the inventors of the present application have found that, with this type of magnetorheological damper in the form of a suspension rod, when it is installed in a pulsator washing machine, the damping effect gradually deteriorates after a long period of use.
The inventor further finds that when the washing outer cylinder vibrates to drive the piston rod to move along the axial direction of the washing outer cylinder, the piston rod is limited by a few parts in the whole length of the magnetorheological damper, and particularly the tail end of the piston rod is connected with the piston, so that the movement direction of the piston rod is easy to deviate in the process that the piston rod drives the piston rod to reciprocate, the piston is easy to deviate from the cylinder when sliding in the cylinder body, the piston rod is bent and deformed, and the damping effect is weakened.
In addition, the magnetorheological damper in the prior art is generally sleeved with a shell which can slide relatively outside the cylinder body, so that the structure is complex, the movement direction of the piston rod is more easily deviated in the process that the piston rod drives the piston rod to reciprocate, and the piston of the magnetorheological damper is easily deviated from the cylinder when sliding in the cylinder body, so that the piston rod is bent and deformed, and the damping effect is weakened.
In conclusion, the existing magnetorheological damper in the prior art is not suitable for the pulsator washing machine.

The adjustable damping suspender has a simple structure. When the coil is not electrified, a magnetic field cannot be generated around the coil, so that the magnetorheological fluid exists in a fluid state; when the coil is energized, its surroundings are filled with a magnetic field, so that the magnetorheological fluid becomes poor in fluidity. The invention can input proper current according to the rotating speed of the washing outer cylinder and the equidirectional coil to achieve the required form of the magnetorheological fluid so as to control the damping of the adjustable damping suspender.
Furthermore, the adjustable damping suspender for the pulsator washing machine, disclosed by the invention, has the advantages that the bottom end of the long suspender is inserted into the cylinder body from the upper end of the cylinder body and penetrates out of the lower end of the cylinder body, so that the long suspender can be well limited by the upper end and the lower end of the cylinder body. When the long suspender drives the piston to slide in the cylinder body, the motion direction of the long suspender is not easy to deviate, thereby not easy to generate flexural deformation, and simultaneously the piston is not easy to deviate from the cylinder. Therefore, the adjustable damping suspension rod has good damping effect and long service life, and is particularly suitable for the pulsator washing machine.
Furthermore, the upper end cover and the lower end cover which are used for sealing the upper end and the lower end of the cylinder sleeve are respectively provided with flanging parts, the upper end cover and the lower end cover comprise a base plate part and a protruding part which extends outwards from the base plate part, the protruding parts of the protruding parts respectively extend into the cylinder sleeve from the upper end and the lower end of the cylinder sleeve, and the periphery of the base plate part is respectively abutted to the flanging parts at the upper end and the lower end of the cylinder sleeve. Through the arrangement, after the adjustable damping suspension rod is installed on the pulsator washing machine, the upper end cover always receives downward acting force applied by the shock absorption seat, and the lower end cover always receives upward acting force applied by the spring, so that the sealing of the cylinder body is ensured. Prevent that the impact of piston to upper and lower end cover in the in-process that reciprocates from leading to cylinder body sealing performance to receive the influence.

The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

Some specific embodiments of the invention will be described in detail hereinafter, by way of illustration and not limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:

FIG. 2 is a schematic close-up view of the adjustable damping boom of FIG. 1;
fig. 3 is a schematic perspective view of a pulsator washing machine according to an embodiment of the present invention.
Detailed Description
FIG. 1 is a schematic perspective view of an adjustable damping boom 10 according to one embodiment of the present invention. As shown in FIG. 1, an adjustable damping boom 10 includes an elongated boom 1, a cylinder 2, a piston 3, and a top mount 6. The top mounting seat 6 is arranged at the top end of the long suspension rod 1 so as to hang the adjustable damping suspension rod 10 on a hanging seat at the top of the shell of the pulsator washing machine. A cavity for containing magnetorheological fluid is defined in the cylinder body 2. The upper end of the cylinder body 2 is formed with a positioning part 223 extending upwards to match with a shock absorption seat of the lower peripheral wall of the washing outer cylinder of the pulsator washing machine, so that the washing outer cylinder is hung on the adjustable damping hanger rod 10 under the action of gravity.
The top mounting seat 6 can be sleeved on the top end of the long suspender 1. The top mount 6 may be similar in construction to the upper tee of the prior art boom and the locator 223 may be similar in construction to the lower tee of the prior art boom. Wherein, the hanging seat and the shock absorption seat are respectively provided with a through hole with the diameter larger than that of the long suspender 1, the long suspender 1 passes through the hanging seat and the shock absorption seat, and the top mounting seat 6 and the positioning part 223 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 washing outer cylinder.
The bottom end of the elongated boom 1 is inserted into the cylinder block 2 from the upper end of the cylinder block 2 and passes out through the lower end of the cylinder block 2 (i.e., the elongated boom 1 penetrates the cylinder block 2 in the axial direction), and the elongated boom 1 is capable of reciprocating in the axial direction with respect to the cylinder block 2. The piston 3 is fixedly sleeved on the long suspender 1 which is positioned in the cavity and can reciprocate along the long suspender 1 in the cavity along the axial direction.
The piston 3 is provided with a coil 32 which can generate a magnetic field when being electrified and a flow channel 31 which axially penetrates through the piston 3, so that the mobility of the magnetorheological fluid in the flow channel 31 can be changed by changing the magnitude of the current in the coil 32. The piston 3 may be made of a ferromagnetic material, and the coil 32 is wound inside the piston 3. A ring cavity may be provided inside the piston 3 so that the coil 32 is wound inside the piston 3, and the flow passage 31 may be provided outside the ring cavity. The flow channel 31 may be C-shaped in cross-section in the axial direction.
When the coil 32 is energized, a magnetic field is generated around the coil, and after the magnetorheological fluid in the fluid channel 31 is subjected to the action of the magnetic field, the viscosity of the magnetorheological fluid changes, so that the damping changes.
The cylinder body 2 can be filled with magnetorheological fluid, and when the washing outer cylinder vibrates, the long suspender 1 can drive the piston 3 to reciprocate along the axial direction relative to the cylinder body 2. Specifically, when the piston 3 moves with the elongated boom 1 from bottom to top, the magnetorheological fluid above the piston 3 will flow to the lower side of the piston 3 through the fluid channel 31 due to the continuous decrease of the space above the piston 3. The periphery of the piston 3 is sleeved with an O-shaped ring 33 to prevent magnetorheological fluid on one side of the piston 3 from flowing to the other side through the periphery of the piston 3. That is, during the reciprocating motion of the piston 3 with the elongated boom 1, the magnetorheological fluid can flow from one side of the piston 3 to the other side only via the flow channel 31. Since the long boom 1 penetrates the cylinder body 2, the effective volume of the long boom 1 in the cylinder body 2 does not change during the reciprocating motion.
The distance from the bottom end of the long suspender 1 to the piston 3 is larger than the axial length of the cavity, so that when the piston 3 moves upwards along with the long suspender 1 to the upper end of the cylinder body 2, the bottom end of the long suspender 1 enters the cylinder body 2 to cause the cylinder body 2 to be unsealed.
A wire slot 34 for arranging wires for supplying power to the coil 32 is provided in the elongate boom 1 and the piston 3, the wire slot 34 extending from the piston 3 to the top end of the elongate boom 1. The wires may be connected to a power source via the top mount 6. For the adjustable damping boom 10 of the present invention, when the coil 32 is not energized, no magnetic field is generated around it, so the magnetorheological fluid exists in a fluid state; when the coil 32 is energized, its surroundings are filled with a magnetic field, so that the magnetorheological fluid becomes poor in fluidity. Specifically, when the current becomes large, the magnetism of the coil 32 becomes large, the fluidity of the magnetorheological fluid is reduced, and the damping force is increased; when the current becomes small, the magnetism of the coil 32 becomes small, the fluidity of the magnetorheological fluid is enhanced, and the damping force is reduced. Appropriate current can be input to the coils 32 according to the rotating speed of the washing outer cylinder to achieve the required form of the magnetorheological fluid, so that the damping of the adjustable damping suspender 10 is controlled.
In addition, the adjustable damping suspension rod 10 for the pulsator washing machine of the present invention can better limit the position of the long suspension rod 1 from the upper and lower ends of the cylinder 2 because the bottom end of the long suspension rod 1 is inserted into the cylinder 2 from the upper end of the cylinder 2 and penetrates out through the lower end of the cylinder 2. When the long suspender 1 drives the piston 3 to slide in the cylinder body 2, the motion direction of the long suspender 1 is not easy to deviate, so that the bending deformation is not easy to generate, and the piston 3 is not easy to deviate from the cylinder. Therefore, the adjustable damping suspension rod 10 has a good damping effect, has a long service life, and is particularly suitable for the pulsator washing machine.
In some embodiments, the cylinder block 2 includes a sleeve 21 and an upper end cap 22 and a lower end cap 23 which are provided at upper and lower ends of the sleeve 21 to seal it, and the positioning portion 223 is formed on the upper end cap 22. The centers of the upper end cap 22 and the lower end cap 23 each have a through hole to allow the elongated boom 1 to pass therethrough and to be reciprocally movable in the axial direction with respect to the upper end cap 22 and the lower end cap 23. Sealing rings 7 are arranged between the long suspension rod 1 and the barrel sleeve 21 and between the upper end cover 22 and the lower end cover 23 to ensure that the cylinder body 2 is sealed.
In a further embodiment, the sleeve 21 may have flanged portions 211 formed to extend radially outwardly from the upper and lower end edges thereof, respectively. The upper end cover 22 and the lower end cover 23 respectively comprise base plate parts 221 and 231 and convex parts 222 and 232 extending from the base plate parts 221 and 231 to the cylinder sleeve 21, the convex parts 222 and 232 of the upper end cover 22 and the lower end cover 23 respectively extend into the cylinder sleeve 21 from the upper end and the lower end of the cylinder sleeve 21, and the peripheries of the base plate parts 221 and 231 of the upper end cover 22 and the lower end cover 23 are respectively abutted with the flanging parts 211 at the upper end and the lower end of the cylinder sleeve 21; wherein the positioning portion 223 extends upward from the base plate portion 221 of the upper end cover 22.
In a further embodiment, the adjustable damping boom 10 further comprises a boom seat 5 and a spring 4, the boom seat 5 being fixedly arranged at the bottom end of the elongated boom 1; the spring 4 is sleeved on the long suspender 1 and is arranged between the suspender seat 5 and the lower end of the cylinder body 2. The hanger rod seat 5 can be sleeved at the bottom end of the long hanger rod 1 or welded at the bottom end of the long hanger rod 1. When the elongated boom 1 moves upward in the cylinder 2, the spring 4 shortens; when the elongated boom 1 moves down in the cylinder 2, the spring 4 expands.
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 a washing tub of the pulsator washing machine in a suspended state within a housing thereof. 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 booms 10 as in any one of the previous embodiments, a housing 110, a washing tub 130, and a washing tub 120. The washing tub 130 is rotatably disposed in the washing tub 120. 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 washing tub 120 is disposed in the casing 110, and a plurality of shock-absorbing seats 121 matched with the positioning parts 223 of the adjustable damping hanger rods 10 are distributed on the circumferential wall of the lower part of the washing tub 120, and the top mounting seats 6 and the positioning parts 223 of the plurality of adjustable damping hanger rods 10 are respectively connected with the plurality of hanging seats 111 of the casing 110 and the plurality of shock-absorbing seats 121 of the washing tub 120, so as to hang the washing tub 120 in the casing 110.
In the preferred embodiment, the washing tub composed of the washing tub 130 and the washing tub 120 is suspended by 4 adjustable damping booms 10, and the angle between the horizontal projections of the adjacent adjustable damping booms 10 is 90 degrees. That is, the 4 adjustable damping suspension rods 10 are uniformly and radially distributed along the circumference of the washing tub 120, so that the 4 adjustable damping suspension rods 10 are uniformly stressed.
The motor 150 is installed below the washing tub 120. The driving shaft of the motor 150 is connected with the washing inner tub 130 through the washing outer tub 120, and can drive the washing inner tub 130 to rotate. The adjustable damping boom 10 controls the amount of current provided to the coil 32 based on the speed signal fed back from the motor 150 to produce a matched damping force. Therefore, the flowability of the magnetorheological fluid is changed by utilizing the change of the magnetism of the electrified coil 32, so that the aim of adjusting the damping in real time is fulfilled.
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.
