Abstract
The invention discloses a gimbal device of a rolling drum-type washing machine. The gimbal device comprises at least two annular chambers which are in coaxial with a rolling drum and are arranged at the edge of the rolling drum, wherein at least one chamber is a sphere gimbal provided with a grounder; and at least one chamber is a liquid gimbal provided with flowing liquid. The two different counterweights of the grounder and the liquid are utilized for respectively generating at least two counterbalances with different reaction speeds, thereby improving equilibrium state of rotation when the rolling drum of the washing machine dehydrates. When the rotation speed is less than the point of resonance of the rolling drum and an outer drum, the liquid gimbal absorbs vibration. When the rotation speed exceeds the point of resonance and is stabilized, the sphere gimbal generates high degree of vibration to absorb the vibration of the outer drum. For offset exceeding sphere volume, the liquid gimbal absorbs the vibration. The gimbal device can restrain vibration amplitude of the outer drum when starting and stably rotating, and realizes the purposes of low vibration, low noise and low cost.
Description
Technical field
The present invention relates on a kind of washing machine for preventing or reduce the balanced component of vibration especially a kind of balance ring for tumbling-box washing machine.
Background technology
Along with the development of washing machine technology, the washing capacity of washing machine constantly increases, and the rotating speed of spin-dry is also in continuous raising, and the vibration displacement problem that in the spin-dry process, dehydration tumbler produces more and more becomes the bottleneck of washing machine technology sustainable development.
In order to overcome, the dehydration tumbler that in the above-mentioned washing machine course of work, laod unbalance causes is eccentric, vibration, has used the gimbal structure on washing machine.In design before, this gimbal is divided into two kinds: liquid injection type balance ring and ball formula gimbal, these two kinds of forms are passive form, to the response of vibration, are only to obtain balance by himself physical action effect.What wherein in the fluid balance ring, inject is water or salt solution, but due to its by weight of liquid itself configuration carry out balance, in counteracting bias that can only part than under the slow-speed of revolution or uneven; The pouring-in more optimized structure of the relative liquid of ball formula gimbal, react faster, but the vibration proof produced under high speed conditions and anti-eccentric effect do not have the pouring-in successful of liquid.
What in Fig. 1, show is the fundamental diagram of existing ball formula mechanical balance ring, (mainly refer to that washing machine is in the drying dehydration process here) in the washing machine course of work, the clothing that is placed on washer dewatering cylinder inside can produce a centrifugal force F1 in rotary course.If any gimbal is not set on this dehydration tube, dehydration tube can cause serious vibration because this lasting centrifugal force F1 produces eccentric rotary so, cause and play cylinder, finally affect the normal operation of washing machine the service life of reducing washing machine, and when be provided with ball formula mechanical balance ring on washer dewatering cylinder after, this ball formula mechanical balance ring can produce the reverse restoring force F2 with the centrifugal force F1 of above-mentioned dehydration tube in the washing machine course of work, and the eccentric rotary of washer dewatering cylinder is played to supression to a certain extent.The operation principle of the fluid balance ring on washing machine and the operation principle of other mechanical type gimbal and this ball formula mechanical balance ring is basically identical, but these existing balanced ring for washing machines have its intrinsic shortcoming, it can only produce effect in a fixed load offset scope.Because its sphere of action is proportional with steel ball quality, along with the load offset increases, expect corresponding effect, will increase steel ball quality; But steel ball quality can not unrestrictedly increase, because can make the cylinder distortion under the centrifugal force of the too large generation of quality and the eccentric centrifugal force acting in conjunction produced, cause a series of problems such as inner/outer tube friction collision.
Therefore, part Study personnel have proposed the employing multiring structure, and the gimbal structure in a plurality of ring packing chambeies arranged side by side is set in a gimbal.
For example, the Chinese patent that application number is 96123928.X discloses a kind of tumbling-box washing machine, comprises shell; The bucket suspended in midair in shell; The revolvable rotating cylinder be arranged in bucket of level; Make the engine of rotating cylinder rotation; And bascule.Bascule has cavity volume and the many balls mobile at cavity volume that is placed in respectively rotating cylinder both sides ring-shaped groove.Cavity volume makes ball move freely along cavity volume containing the liquid of scheduled volume.Each cavity volume is by being connected to form with the rotating cylinder side plate.On side plate, first cannelure inwardly forms, and forms second groove corresponding with first groove on the planar plate members matched.
Secondly, the Chinese patent that application number is 97113699.8 discloses a kind of bascule for roller washing machine, comprising: by side plate and the rotating rotating cylinder that forms by the interconnective front and rear panels of side plate; Be arranged on front and rear panels, concentric and towards two of front or rear panel side-prominent ring-type seat rings with rotating cylinder, and many spheroids that is arranged in seat ring.
Again, the Chinese patent that application number is 200510099928 also discloses a kind of balancer of washing machine.This balancer comprises: the balancer ring, and it is arranged on cylinder, and this balancer ring has the liquid accommodation space for accommodating liquid; A plurality of the first baffle plates, it is arranged at the inside of balancer ring; And a plurality of second baffles, it is arranged between the first baffle plate, so that the first baffle plate and second baffle alternative arrangement, wherein the height of second baffle is lower than the height of the first baffle plate.While in washing machine, producing abnormal vibrations, second baffle prevents springing up of salt solution effectively.
Although the prior art of enumerating above-mentioned discloses and a plurality of filler chambeies arranged side by side has been set in same gimbal to strengthen the technical scheme of washing machine work balance, but it is all to fill identical filler in each filler chamber, this can not well eliminate the uneven urceolus vibration produced of dehydration in the washing machine course of work, beat the cylinder problem, especially the different load offset for wet wash in cylinder, can only produce effect for a load offset among a small circle, once the load offset is excessive, also there will be the urceolus vibration, beat the cylinder problem.
In view of this special proposition the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide a kind of in conjunction with spheroid and two kinds of dissimilar balanced ring for washing machines of liquid and the balance ring of the tumbling-box washing machine obtained, urceolus vibration amplitude while when this balance ring can suppress to start, reaching stable rotation, realize low vibration, low noise, low cost.
Another object of the present invention is to provide this balance ring to obtain balance method.
For solving the problems of the technologies described above, the present invention adopts the basic conception of technical scheme to be: a kind of balance ring of tumbling-box washing machine, described balance ring is comprised of at least two annular compartments that are arranged on the cylinder edge, wherein at least one chamber is the Balance for Rotating Ball ring that is provided with spin, and having a chamber at least is the fluid balance ring that is provided with working fluid, utilize two kinds of different counterbalances of spin and liquid, produce respectively at least two kinds of equilibrant force that reaction speed is different, and then the poised state of cylinder while improving laundry machine dehydration.
Described each annular compartment coaxially arranges on cylinder, and the plane at each annular compartment place of this balance ring is parallel to each other or overlaps.
Described balance ring consists of plastic gimbal lid and gimbal body, cut apart and surround to form several cannelures by the projection wall body on described gimbal body, gimbal lid and gimbal body fastening are carried out to the deposition welded seal put into respectively spin and liquid in above-mentioned cannelure after.
Projection wall body on described gimbal body is provided with the buckling parts with gimbal lid coupling, and annular compartment left and right top side wall is provided with the barrier that burr and abrasion powder while preventing deposition fall into chamber interior.
Be distributed with a plurality of block reinforcements along annular radial at the bottom of cannelure on described gimbal body.Impose on the revolving force of liquid in the fluid balance ring by barrier rib, make performance when resonance point reduce the effect of vibrating.
Perpendicular to drum shaft to the annular chamber locular wall on along the circumferential direction establish bossed support wall body.The support wall body of this projection together with the annular compartment sidewall as the seating surface of balls tumble, prevent that by subtracting spherular rolling radius the spheroid rotation occurred because of inertia from lagging behind, can reduce hysteresis, the vibration of the urceolus while reducing resonance point with respect to drum rotating.
Described balance ring consists of a Balance for Rotating Ball ring and a fluid balance ring, the Balance for Rotating Ball is located on the outer ring of fluid balance ring, be filled with n stainless steel ball in the Balance for Rotating Ball ring, the pass of itself and annular chamber girth E is nD≤E/2, also be filled with reduce between stainless steel ball and stainless steel ball and annular compartment inwall between the silicone oil that rubs, be filled with sodium-chloride water solution and/or calcium chloride water in the fluid balance ring, cumulative volume is not more than 1/2 of this cavity space volume.
The different equilibrant force of described at least two kinds of reaction speeds is that the different inhibitory action that cylinder load bias measured by two kinds of fillers determine, rotating speed when following, absorbs vibration by the fluid balance ring at cylinder and urceolus resonance point; When rotating speed is stablized by resonance point, the vibration of height vibration absorption absorption urceolus is waved in the Balance for Rotating Ball environment-development; Offset for surpassing the spheroid total amount, absorb vibration by the fluid balance ring.
Annular compartment inner stuffing gross mass m1, the load offset m2 that cylinder load when rotation produces, the offset m3 of program setting, when load offset m2 hour, i.e. m2≤m3, the Balance for Rotating Ball ring plays a role fast, suppresses the out-of-balance force that eccentric load produces; When the load offset is larger, being m2-m1≤m3, is at first that the Balance for Rotating Ball ring works, along with the raising of washing machine drum rotating speed, the centrifugal force that eccentric load produces increases, and fluid balance ring and the Balance for Rotating Ball ring concur the out-of-balance force produced while restraining the cylinder high speed rotating.
In dehydration, during rotating speed when the spheroid centrifugal force in the Balance for Rotating Ball ring is greater than gravity, bear spheroid centrifugal force the annular compartment sidewall and perpendicular to drum shaft to the seating surface of annular chamber locular wall while forming the spheroid rotation, this seating surface makes the actual rolling radius of spheroid reduce, and then reduces hysteresis, the vibration of the urceolus while reducing resonance point with respect to drum rotating.
After adopting technique scheme, the present invention compared with prior art has following beneficial effect.
In the situation that washing machine load offset is low, the Balance for Rotating Ball ring can very fast playing a role, but in the situation that the load offset is high, lifting along with rotating speed, this the Balance for Rotating Ball ring can not effectively play a role, and the effect of the now common performance of aforesaid liquid gimbal and this Balance for Rotating Ball ring can make up the deficiency of single performance just.Therefore, at this cylinder load offset under different condition, can be good at restraining by the present invention urceolus vibration, the cylinder that the laundry machine dehydration imbalance causes and beat the urceolus phenomenon, make the washing machine smooth working.

The specific embodiment
What mean as Fig. 2 is the vertical sectional schematic diagram of tumbling-box washing machine of the embodiment of the present invention.Only put down in writing the basic constituent element of washing machine drum and gimbal in this figure, other key element of washing machine, do not charge to diagram such as omissions such as control panel switches.The tumbling-box washing machine formation mainly comprises: the housing of sheet iron system, support the synthetic resin base frame processed of this housing, the synthetic resin of being supported by elasticity by supporting structure from base frame urceolus processed, keep the ripple film of water-stop between the front of urceolus and housing, with ripple film, coordinate, be arranged on the glass door on housing, be arranged on the urceolus rear portion and be used for the flange of supporting rotating shaft, be positioned at the urceolus bottom, the limbers, side in front, with the SUS of peristome cylinder processed, be connected to the bottom of urceolus, urceolus with the aluminum casting system of the bearing of the rotating shaft of rotor and motor stator above the other end is equipped with and supports supports, and the rotating shaft of cylinder is the maintenance level or is inclined to set for making front side exceed some than inboard (rear side).
When washing, rinsing, dehydration, the rotation of non-carbon brush motor head roll; During dehydration, by the vibrating detector in controller, carry out vibration detection, determine by, Spin-up and non-by, the judgement that stops according to the benchmark that sets in advance.These drivings and vibration detection and the control of advancing draining etc. are all to be undertaken by controller.
Urceolus Vibration Condition when as shown in Figures 3 to 6, Fig. 3 and Fig. 4 mean the fluid balance ring is housed.In Fig. 3, on washing machine drum, do not install under the condition of any gimbal, the load offset (amount of unbalance) of corresponding washing machine drum can mean with the straight line C1 of a linear change with the amplitude of urceolus vibration, in figure, can find out, the load offset of washing machine drum is larger, the urceolus Oscillation Amplitude of washing machine is just larger, and the angle of this straight line and transverse axis is θ; On washing machine drum, be equipped with under the condition of fluid balance ring, also form the proportional relationship of a substantially linear between the load offset of its cylinder and the Oscillation Amplitude of washing machine, with straight line C2, mean in the drawings, the angle of this straight line C2 and transverse axis is α and α<θ; In figure, can find out, under the condition of identical load offset, the vibration of washing machine amplitude that the fluid balance ring has been installed is less than the vibration of washing machine amplitude that gimbal is not installed.As shown in Figure 4, curve L1 is the urceolus Oscillation Amplitude while any gimbal not being installed, and curve L2 is the urceolus Oscillation Amplitude when fluid balance ring is installed.Fluid balance ring shock absorption of (a part in consulting Fig. 4) when starting resonance point is very high, this miniaturization for product is a kind of very effective means, but (consult a part in Fig. 4) when stablizing, almost do not reduce the ability of vibration while also being High Rotation Speed, especially when the High Rotation Speed noise that is accompanied by cylinder becomes large High Rotation Speed, the effect of fluid balance ring is not sufficient.
Below will describe the Balance for Rotating Ball ring.Distinguish to illustrate its action according to drum rotation speed.
Fluid balance ring and the Balance for Rotating Ball ring are identical basically, but at rotating speed during lower startup, because spheroid can not get sufficient revolving force, rotation lags behind cylinder and inner bias, therefore, as shown in Figure 5, large variation occurs because of spheroid in eccentric relative position relation in the vibration of urceolus, especially, when being present in 200～300rpm of resonance point, is accompanied by covibration, spheroid itself becomes offset makes the urceolus high vibration, therefore with housing, collides sometimes.For anti-phenomenon here, enclose the high oil of viscosity and prevent sharply moving of spheroid, but effect is inadequate, according to circumstances appends sometimes antihunting device (damper) and solves.On the other hand, the fluid balance ring do not need need to guarantee swing-around trajectory as the Balance for Rotating Ball ring, and therefore barrier rib can freely be set imposes on liquid in rotation power, can when resonance point, bring into play and reduce the effect of vibrating.
Rotating speed is by after resonance point, and the Balance for Rotating Ball ring can be brought into play very high vibration absorption.Fig. 6 is that wherein, O ' is centre of the drum, O to the explanation of the action of the spheroid in rotation " be pivot, the centrifugal force that F ' is centre of the drum's direction, F " be the centrifugal force of pivot direction.Because of the existence of offset F, the O ' of centre of the drum and pivot O " inconsistent, pivot O " be positioned at the side of offset F.The component Δ F that now acts on the centrifugal force of spheroid 6 becomes makes the opposition side of spheroid 6 to offset F, offset the power that eccentric direction moves, by this power, make spheroid move, move, until offset F becomes 0, the vibration that is urceolus becomes 0, certainly the total amount of spheroid is also limited, and the relation of offset and urceolus vibration as shown in Figure 7.
What Fig. 7 showed is exactly the different-effect comparative descriptions that balance ring of the present invention and existing balanced ring for washing machine produce.In coordinate plane in Fig. 7, its transverse axis means the offset of washing machine drum load wet wash, i.e. amount of unbalance, and the representative of the longitudinal axis in coordinate system is exactly the Oscillation Amplitude of washing machine urceolus.On washing machine drum, do not install under the condition of any gimbal, the load offset of corresponding washing machine drum and the amplitude of vibration can mean with the straight line C1 of a linear change, in figure, can find out, the load offset of washing machine drum is larger, the Oscillation Amplitude of washing machine is just larger, and the angle of this straight line and transverse axis is θ, on washing machine drum, be equipped with under the condition of fluid balance ring, also form the proportional relationship of a substantially linear between the load offset of its cylinder and the Oscillation Amplitude of washing machine drum, with straight line C2, mean in the drawings, the angle of this straight line C2 and transverse axis is α and α<θ, in figure, can find out, under the condition of identical load offset, the Oscillation Amplitude that the washing machine urceolus of fluid balance ring has been installed is less than the vibration of washing machine amplitude that gimbal is not installed, the effect that the washing machine of installation the Balance for Rotating Ball ring produces is more complicated, at first the reaction of the Balance for Rotating Ball ring is better than the fluid balance ring, it can fully play effect under the condition lower at washing machine drum load offset, so just produced the first half section straight line portion of C3 broken line in figure, the angle of the straight line of this straight line portion and transverse axis is less than above-mentioned α simultaneously, θ, but after the point of the offset threshold values b of a corresponding transverse axis, this the Balance for Rotating Ball ring but can not produce same effect as the fluid balance ring, along with offset is higher, the rate of change of its Oscillation Amplitude obviously is greater than the Oscillation Amplitude that the fluid balance endless belt comes, until, the Oscillation Amplitude that Oscillation Amplitude comes higher than the fluid balance endless belt, and broken line C4 is the corresponding situation that load offset with its Oscillation Amplitude of washing machine urceolus of the present invention are installed, coinciding of the first stage of this broken line C4 first stage and broken line C3, show in the situation that lower than load offset b, the Balance for Rotating Ball ring in bascule of the present invention in action, in action, its angle α with the angle of transverse axis and straight line C2 is identical for fluid balance ring in the second segment of the broken line by after threshold values b place shows bascule of the present invention.Can find out, bascule of the present invention combines the advantage of existing fluid balance ring and the Balance for Rotating Ball ring, and no matter the variation of load offset is much, and the Oscillation Amplitude produced in the rotation process of washing machine drum is all less and change steady.Although increased separately a gimbal structure in prior art, be in fact all the stack of carrying out on single gimbal basis, this stack can not produce technique effect as described in the present invention.
