Description
Technical field
The utility model relates to a kind of washing machine, especially relates to a kind of balance ring and has the roller washing machine of this balance ring.
Background technology
Washing machine is in dehydration, and due to the randomness that clothing distributes, clothing always produces uneven distribution in dehydration barrel, namely our said eccentric load usually.When dehydration barrel High Rotation Speed, the centrifugal force that eccentric load produces is equivalent to the exciting force in forced vibration, can make dehydration barrel high vibration.The vibration of dehydration barrel can cause the high vibration of complete machine.These vibrations not only can produce very large noise, and give on user's sense organ and bring very large sticky feeling, but also the service life that can greatly reduce washing machine machinery and electrical component.When eccentric load is larger, even directly cause the damage of washing part parts.Therefore, alleviate as far as possible the infringement that eccentric load brings to washing machine necessary.Reduce the infringement of eccentric load to washing machine, can start with from two aspects, reduce eccentric load, or the centrifugal force that produces of balance eccentric load.From the former, starting with, is exactly the eccentric resist technology of software; From the latter, starting with, is exactly balance ring technology.
At present the eccentric resist technology of conventional software is to select a suitable rotating speed, and generally at 90-120 revs/min, under this rotating speed, the information such as the rotating speed of testing of electric motors, power, by software analysis, calculating, obtains eccentrically loaded sizes values.Then by this value and the contrast of the default protection value of software, while being only less than protection value, just can enter normal high speed dewatering.Otherwise just reduce rotating speed, allow clothing redistribute, and then retest, until pass through.It is random whether redistributing clothing, and the number of times of redistribution clothing depends primarily on the complexity that clothing is evenly distributed, and also depends on default bias protection value simultaneously; this value is established greatly, and percent of pass is just high, easily realizes dehydration; but vibration of washing machine is large, will be affected service life.Otherwise this value is established littlely, vibrate littlely, washing machine better but is not easy to realize dehydration by protected, there will be the phenomenon of not dewatering, or dehydration continuity is for a long time.
What balance ring technology was at present common is divided into two kinds, injects the fluid balance circle of salt solution and the steel ball balance ring of use steel ball.The open circle that fluid balance circle is formed by upper and lower two working of plastics gummed, the inside of open circle is provided with a plurality of dividing plates, and filling liquid.For increasing liquid specific gravity. and guarantee can not freeze when extremely frigid zones is used, conventionally all adopting the supersaturated brine of concentration approximately 24%, injection rate is about 50% left and right of open circle internal volume.Steel ball balance ring is formed by upper and lower two working of plastics gummed equally, inside is hollow, but there is no dividing plate, put into the steel ball of approximately 0.5 kilogram weight, the accumulation length of its diameter approximates 1/5 to 1/6 balance ring girth, distribution angle approximately 60 to 75 degree during solid matter, have also injected appropriate thick oil.When dehydration, balance ring is along with dehydration barrel is rotated together, liquid in balance ring or steel ball meeting automatic moving are to the relative side of clothing eccentric load, the centrifugal force opposite direction that the centrifugal force of its generation and eccentric load produce, mutual balance, eccentric impact is reduced, so just played the effect of automatic deviation correction, can effectively reduce the vibration of washing machine.
In recent years; the washing capacity of washing machine constantly expands; dehydrating speed improves constantly; washing machine is also more and more higher to control and the eccentrically loaded requirement of balance; therefore; Software Protection Technique and balance ring technology are all making constant progress, but generally speaking, the development of Software Protection Technique will be faster than balance ring technology.The volume of salt solution balance ring takies greatly larger space, and ball balance ring is evenly distributed at clothing, and while there is no bias in turning barrel, balance ring itself has not become bias on the contrary, makes originally also non-vibrating washing machine produce vibration.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, 3, balance ring 6 comprises toroidal shell 7 and several group of rollers 8, and toroidal shell 7 inner hollow are fixedly mounted on the turning barrel of washing machine coaxially; Group of rollers 8 is arranged in toroidal shell 7 inner chambers, and along circumferencial direction, moves in toroidal shell 7 inner chambers, and group of rollers 8 consists of retainer 802 and at least 2 rollers 801, and the quantity of the roller 801 in a common group of rollers 8 is at 2 ~ 6.Roller 801 is rotatably arranged in retainer 802, the center line of roller 801 is parallel with the center line of toroidal shell 7, angle C(during several group of rollers 8 dense arrangement is if Fig. 9 is a) between 105 ° ~ 135 °, angle C the best during some group of rollers 8 dense arrangement is 120 °, the angle of the quantity of group of rollers 8 during by its dense arrangement determined, is provided with 4 group of rollers 8 in the embodiment of Fig. 1.Lubricating oil is full of in the inner chamber of toroidal shell 7.
As shown in Figure 4,5, roller washing machine comprises that 1,2 of outer container hangs spring 2 and bucket portion is filled to 3 is suspended on outer container 1, and 3 or 4 shock absorbers 4 connect bases 5 and fill 3 with bucket portion.Bucket portion fills 3 and comprises turning barrel 302, balance ring 6, outer barrel 303 and balance weight 301 etc., and balance weight 301 is arranged in outer barrel 303, and balance ring 6 is coaxially arranged on the inwall of turning barrel 302 openends, follows at turning barrel 302 and rotates together.When dehydration, turning barrel 302 high speed rotating, the clothing skewness in turning barrel 302 will form eccentric load, and bucket portion fills vibration under the 3 centrifugal force excitations that produce at eccentric load, and oscillation trajectory is a circle.When dehydrating speed fills 3 the corresponding rotating speed of resonant frequency higher than bucket portion, vibration displacement direction will progressively move on to the opposite direction of eccentric position.For turning barrel 302, be equivalent in the eccentric shaft rotation round towards eccentric direction skew, the offset distance of eccentric shaft is the amplitude of a bucket portion dress vibration.Balance ring 6 is contained on turning barrel 302 and with turning barrel 302 and rotates around eccentric shaft, and the balance material in the toroidal shell 7 of balance ring 6--roller can produce mobile trend to the large direction of the radius of gyration (direction that eccentric load is contrary).Whether mobile trend is converted into actual movement, depends on whether slippage component is greater than frictional force.In Fig. 6, horizontal horizontal line represents frictional force, and the curve of fovea superior represents slippage component.What trunnion axis represented is the position of roller in toroidal shell 7, and initial point is eccentric position, and 180 ° is eccentric opposite direction position.As seen from Figure 6, the size of slippage component is relevant with amplitude, toroidal shell radius and the position of roller in toroidal shell.At eccentric position and its opposite direction position, there are 2 self-locking areas that roller can not roll.
Balance ring in the utility model, retainer 802 connects together 3 rollers 801, forms a group of rollers 8.Group of rollers 8 is contained in toroidal shell 7.Roller 801 is that the diameter of being made by structural steel is approximately 10-25 millimeters of D(), length is approximately 10-40 millimeters of L() cylinder, surface has very high fineness to reduce coefficient of friction, can select suitable draw ratio L/D according to the needs of balance ring overall structure size.The highstrenghtpiston that retainer 802 use are lightweight, intensity is high makes.Retainer 802 is separated roller 801, and clamps roller 801, makes roller 801 can only rotate (rolling), can not twist (deflection).There is very high fineness on the surface that retainer 802 contacts with roller 801 to reduce coefficient of friction.Can change the centre-to-centre spacing that is connected roller by changing the physical dimension A of retainer 802, thus the distribution angle C(while changing group of rollers solid matter (dense arrangement) as Fig. 9 a).A retainer 802 connects 2--6 roller 801 and forms group of rollers 8.The quantity that group of rollers 8 specifically contains roller 801 depends on roller diameter, and roller diameter is large, and contained roller is just few, and roller diameter is little, and contained roller is just many.
The effect of retainer 802 is to keep roller in rolling process, do not produce deflection and slow down shock, and retainer can also make a plurality of rollers collaborative mobile, is conducive to reduce self-locking area, increases balanced capacity.In addition, retainer can also regulate roller distribution angle during solid matter in toroidal shell 7, makes it be greater than self-locking area, the vibration being caused by balance ring itself when overcoming or reducing there is no bias in turning barrel 302.
Toroidal shell 7 is made by highstrenghtpiston.Inner chamber-the raceway of toroidal shell 7 has very high fineness to reduce coefficient of friction.Toroidal shell 7 has certain integral rigidity, to resist the distortion of circumferencial direction.In toroidal shell 7, be filled with the extreme pressure lublicating oil of certain viscosity, the coefficient of friction of the inner chamber of toroidal shell 7 is the smaller the better, and under centrifugal action, for oil film is not racked, extreme pressure lublicating oil can be better than plain oil.
As seen from Figure 6, the size of slippage component is relevant with the ratio of toroidal shell radius with amplitude, and the range size of self-locking area is except outside the Pass having with this ratio, also relevant with frictional force.For example, after toroidal shell radius and coefficient of friction are determined (250 millimeters of toroidal shell radiuses and coefficient of friction 0.01), amplitude size has just determined the scope of self-locking area.The large self-locking area of amplitude scope is just little, and the little self-locking area of amplitude scope is just large.Corresponding with Fig. 6, what Fig. 7 a represented is that amplitude is the self-locking area scope of 5.0 o'clock (B/R=0.02), and Fig. 7 b represents, is that amplitude is the self-locking area scope of 12.5 o'clock (B/R=0.05).
When dehydration has just started, rotating speed is lower, the vibration displacement of bucket portion dress and eccentric in same direction.When dehydrating speed reaches the corresponding rotating speed of barrel portion dress resonant frequency, vibration displacement and bias differ 90 degree.When dehydrating speed is further brought up to about 300 revs/min, (each system is different, test definite) time, the vibration displacement of bucket portion dress is contrary with regard to fundamental sum eccentric direction, and the amplitude that at this moment bucket portion fills is many greatly during than the high speed dewatering of 1000 revs/min of left and right.Therefore the utility model has adopted the approximately 30 second time of the of short duration maintenance of rotating speed 300 revs/min of left and right, allows group of rollers when this rotating speed, move to eccentric opposite location or suitable equilbrium position.
Balance ring is in equilibrium process, and along with the change of group of rollers position, the amplitude of bucket portion dress is also changing.Balance ring does not also work at the beginning, and amplitude is larger, and self-locking area is less.The group of rollers in self-locking area all can constantly not move to eccentric opposite direction.Along with the movement of group of rollers, eccentric by balance progressively, amplitude reduces.When amplitude reduces, the scope of self-locking area constantly expands, and movably group of rollers is fewer and feweri.Until all group of rollers fall into self-locking area, no longer move, the equilibrium process of roller balance ring finishes.If bias is larger, be balanced rear amplitude still larger, self-locking area is still less, and group of rollers is at eccentric opposite direction solid matter, and equilibrium process finishes.
The radius of toroidal shell 7 of take is 250 millimeters, coefficient of friction 0.01, and amplitude is the mobile status that example illustrates group of rollers while being just 5 millimeters.From Fig. 6, see that 0 to 30 degree and 150 to 180 degree are self-locking area.Correspond in Fig. 8, it is self-locking area that angle beta be take interior.The first group of rollers in Fig. 8 has fallen into self-locking area, no longer moves.A roller of the 4th group of rollers has also fallen into self-locking area, if there is no retainer, this roller can not move yet.Because this roller is in close eccentric position, not only do not have balanced action, also can aggravate imbalance.At this moment retainer starts to play a role, other 2 rollers of same group are in non-self-locking area, when the average slip component of whole group of roller is greater than frictional force, just the roller of self-locking area can be pulled out to self-locking area, the direction contrary to bias moves, and improved the balanced capacity of roller balance ring.
The 3rd group of rollers in Fig. 8 and the second group of rollers are in non-self-locking area, moving to eccentric opposite direction under the effect of slippage component.According to Fig. 6, the slippage component of the 3rd group of rollers is greater than the second group of rollers, so its translational speed also may be greater than the second group of rollers, and catch up with the second group of rollers and produces shock.During the second group of rollers migration self-locking area, also may knock the first group of rollers no longer having moved in self-locking area.The retainer 802 of plastic construction can slow down shock.
If it is very even that the clothing in turning barrel 302 distributes, there is no bias, originally should not vibrate, but due to the group of rollers possibility skewness in balance ring, also can cause vibration.If it is more even that group of rollers distributes, the amplitude of bucket portion dress vibration is very little, and self-locking area is very large, and all group of rollers all fall into self-locking area, do not have group of rollers to roll, and the vibration that balance ring produces is also little, but this state is actually rare.The most all group of rollers are all closely packed in one side of balance ring, and the weight of roller has become bias, and bucket portion dress produces larger vibration.
Can be by changing physical dimension A(Fig. 2 of retainer 802) change the centre-to-centre spacing that is connected roller 801, thereby change the distribution angle of group of rollers solid matter, (Fig. 9 is a).The distribution angle C of group of rollers solid matter is that 120 about degree are that suitable (Fig. 9 a), if there is no retainer 802, the direct solid matter angle of roller can much smaller (Fig. 9 b), and this will improve the duty of balance ring while there is no bias in turning barrel 302.In the present embodiment, the gross weight of roller 801 is 0.5 kilogram of left and right, and the balanced action too gently not having too heavyly can become very high to the strength and stiffness requirement of balance ring raceway (toroidal shell).
If there is no bias, group of rollers solid matter in turning barrel 302 is modal state, at this moment group of rollers itself has become bias, makes barrel portion's dress produce vibration, and amplitude generally can be greater than 5 millimeters, can be less than ± 30(60 of self-locking area) degree.After having had retainer, it is large that solid matter angle becomes, and makes a part of group of rollers drop on non-self-locking area.The group of rollers of non-self-locking area moves the opposite direction to solid matter, continuous movement along with removable group of rollers, the eccentric summation that roller produces diminishes, the amplitude of bucket portion dress vibration diminishes, it is large that self-locking area becomes, movably group of rollers finally all falls into self-locking area and becomes irremovable, thereby makes a barrel vibration for portion's dress be controlled in a less state.
The draw ratio of roller can change, and this makes the physical dimension design of balance ring cross section more flexible, can select suitable size according to the needs of turning barrel structural design.For example, when space that turning barrel is left balance ring at the well-to-do but axial dimension of radial dimension hour, (Figure 10 is a) can to select less draw ratio.Otherwise, when space that turning barrel is left balance ring for is when the very little but axial dimension of radial dimension is well-to-do, can select larger draw ratio (Figure 10 b).
In order to further illustrate operation principle and the process of roller balance ring, below we are divided into and in turning barrel, have compared with large eccentricity, compared with three kinds of states without acceptance of persons in small eccentricity and turning barrel, in conjunction with example and diagram, be described below:
1, in turning barrel, have compared with large eccentricity: roller washing machine enters dehydration, rotating speed is increased to 300 revs/min, and group of rollers random distribution at this moment, as shown in Figure 11 a.Because bias is larger, and be not balanced, the amplitude of bucket portion dress vibration is larger, and corresponding self-locking area is also less, and most group of rollers can drop on non-self-locking area.
The group of rollers of non-self-locking area is rolled to the contrary direction of bias, and bias has obtained some balances, and amplitude reduces thereupon, and corresponding self-locking area will expand, and a part of group of rollers has entered the self-locking area on eccentric opposite, and (Figure 11 b) no longer rolls.
The group of rollers of non-self-locking area is further rolled to the contrary direction of bias, the group of rollers that has just entered self-locking area can not stop immediately rolling under the promotion of kinetic energy, originally fallen into self-locking area group of rollers and may under the promotion of group of rollers that just enters self-locking area, continue to do a small amount of rolling, final group of rollers is closely packed in eccentric opposite direction.Bias has obtained balance to greatest extent.Amplitude reduces thereupon, and corresponding self-locking area further expands (Figure 11 c).
2, in turning barrel, have compared with small eccentricity: roller washing machine enters dehydration, rotating speed is increased to 300 revs/min, and group of rollers random distribution at this moment, as shown in Figure 12 a.Due to small eccentricity, although be not balanced, the vibration amplitude of bucket portion dress is very not large, and larger when corresponding self-locking area has also just started compared with example 1, most of group of rollers can drop on non-self-locking area, only have less group of rollers and fall into self-locking area.
The group of rollers of non-self-locking area is rolled to the contrary direction of bias, and the group of rollers that has originally fallen into self-locking area may continue to do a small amount of rolling under the promotion of group of rollers that just enters self-locking area.Bias has obtained some balances, and amplitude reduces thereupon, and corresponding self-locking area will expand, and more group of rollers has entered the self-locking area on eccentric opposite, and (Figure 12 b) no longer rolls.
The group of rollers of non-self-locking area is further rolled to the contrary direction of bias, the group of rollers that has originally fallen into self-locking area and no longer rolled continues to do a small amount of rolling under the promotion of group of rollers that just enters self-locking area, final group of rollers is distributed in eccentric opposite direction substantially, but solid matter not.Bias has obtained balance to greatest extent, and amplitude reduces thereupon, and corresponding self-locking area further expands (Figure 12 c).
3, in turning barrel, there is no bias, group of rollers distributes spuious: roller washing machine enters dehydration, and rotating speed is increased to 300 revs/min, and at this moment group of rollers distribution is spuious, as shown in Figure 13 a.Owing to there is no bias in turning barrel, roller distributes spuious and does not form compared with large eccentricity, and the vibration amplitude of bucket portion dress is also little, and corresponding self-locking area is also larger, and most of group of rollers has dropped on self-locking area.The group of rollers of non-self-locking area is rolled to the more rare direction of group of rollers.Amplitude reduces thereupon, and the corresponding corresponding expansion in self-locking area, until all group of rollers have entered self-locking area, is no longer rolled (Figure 13 b).
In turning barrel, there is no bias, group of rollers solid matter: roller washing machine enters dehydration, rotating speed is increased to 300 revs/min, due to group of rollers solid matter, roller itself has formed larger bias, and bucket portion dress has produced certain vibration, and the self-locking area of formation (Figure 13 c) is little when spuious more than distribution.Because retainer has increased solid matter angle, the group of rollers at solid matter two ends has dropped on beyond self-locking area.Group of rollers beyond self-locking area is rolled to solid matter group of rollers opposite, and the bias that roller forms diminishes, and consequent vibration amplitude reduces, the corresponding increase in self-locking area (Figure 13 d).Group of rollers continues to roll, and self-locking area further expands, and finally as shown in Figure 13 e, all group of rollers fall into self-locking area, and the bias that roller forms is controlled in less level, and corresponding vibration has also obtained effective control.
