Description
Technical field
The utility model washing machine technical field specifically relates to a kind of fluid balance device of roller washing machine.
Background technology
At present, what the balance sysmte of existing roller washing machine mostly adopted on the market is the solid balance sysmte, the vibratory output a when section that reduces is contained in dehydration.Mainly be to rely on to be installed in the balancing weight with constant weight that a section loads onto, guarantee that cylinder section dress is in the equilbrium position.This mode is to utilize the quiet inertia of the cylinder section dress that balancing weight is installed to suppress a dynamic unbalance problem that section's dress internal burden causes in operation process.But this inhibition can only reduce the vibration displacement amount of whole outer barrel, and the eccentric operating of rotating cylinder is not effectively suppressed, often can cause rotating cylinder barrel distortion, break, the life-span of rotating cylinder bearing also can reduce.
This mode also has other defect: for making vibration in controlled scope, need the very large balancing weight of quality, the weight of load can be far smaller than the overall weight of the cylinder section dress that balancing weight is installed, and causes complete machine weight very large, poor stability when falling; In addition, there is loosening possibility in the screw of fixed weight piece, and then becomes the source of noise; Increase counterweight block structure, cause the complete machine high expensive, because quality is heavy, the increase of cost of transportation, difficult, client is difficult to mobile.
For the deficiency of solid balance weight, the fluid balance ring occurred, and on rotary drum washing machine, be used widely.What inject in the fluid balance ring is water or salt solution, but because itself there is weight in its liquid, when the roller washing machine low-speed running, the fluid balance ring does not only play the effect of balance unbalance loading, also can itself just cause unbalance loading.In the washing machine rotating cylinder in the different unbalance loading situation, prior art fluid balance ring also can't be regulated the liquid own wt automatically makes whole cylinder section dress obtain best balance.
And because the special construction of roller washing machine, the fluid balance ring is not also applied on roller washing machine on a large scale.
The utility model content
The purpose of this utility model is a kind of fluid balance device that can automatically use according to the roller washing machine of the automatic adjustment liquid of actual conditions of invention.
Bascule of the present utility model comprises fluid balance ring, equilibrium liquid storage box, the upper and lower of fluid balance ring has can self-packing hole, corresponding position that can self-packing hole, collapsible joint is set, collapsible joint is connected on the equilibrium liquid storage box by woven hose, and collapsible joint is provided with flowmeter.
Fluid balance device of the present utility model is fixed on the front end face of rotating cylinder of washing machine, by the automatic control type rotating angle, allows and can be connected with collapsible joint in self-packing hole, the equilibrium liquid in the gimbal is carried out what adjusting.
Use this fluid balance device can avoid the very large balance weight of operating weight, significantly alleviate the complete machine weight of roller washing machine.Simultaneously, can eliminate as much as possible the vibration that eccentric load brings for what of the different adjustment bascule inner equilibrium liquid of load, improve running effect.
Description of drawings
Fig. 1, structure chart of the present utility model.
The specific embodiment
Fluid balance ring 1 of the present utility model is mounted on the rotating cylinder 2 of roller washing machine, adds that miscellaneous part consists of whole balance sysmte.
Concrete structure such as Fig. 1: having in the upper and lower of fluid balance ring 1 can self-packing hole, and this hole is the import and export of fluid balance ring 1 internal balance liquid, and being set to can be self-packing, is leakage when preventing from not operating.Because the rotation mode of roller washing machine is different, so consideration can not affect rotation to the adjusting of the equilibrium liquid of gimbal inside, the means of taking are to adopt telescopic joint style: the not position of rotation at washing machine arranges equilibrium liquid storage box 3, connect out two woven hoses 8,9 on the equilibrium liquid storage box 3, owing to can the setting of self-packing hole be one on the other, so corresponding upper tubing 8 and lower woven hose 9 that woven hose is defined as, collapsible joint 5,6 is set on the other end of woven hose, and on woven hose, flowmeter 4 is set also, 7.Arrange collapsible joint 5,6 fixed position all on corresponding the gimbal can self-packing hole, be that collapsible joint is by stretching, can be connected self-packing hole and form and connect, when rotating cylinder 2 is static, allow fluid balance ring 1 and equilibrium liquid storage box 3 UNICOMs, internal balance liquid can flow by between.Easily as can be known, according to requirement of the present utility model, also need to have water pump, the equilibrium liquid of whole system can be flowed.Water pump can directly be arranged in equilibrium liquid storage box 3 inside.
The course of work: after the washing machine starting, the washing machine sensor-based system is judged the unbalance loading situation.When unbalance loading less, when rotating speed is low, the washing machine rotating cylinder suspends, the position sensor of motor makes two of fluid balance ring 1 on the rotating cylinder 2 can aim at the collapsible joint 5 that is installed in outer barrel in self-packing hole, 6 places, the controller control collapsible joint 5 of washing machine, 6 and the fluid balance ring on the hole connect, control again water pump and flowmeter 4 in the equilibrium liquid storage box 3,7 work, equilibrium liquid in the fluid balance ring 1 flows to equilibrium liquid storage box 3 by lower woven hose, can calculate equilibrium liquid weight in the fluid balance ring by the flowmeter variable, when weight reaches setting value, water pump and flowmeter in the controller control equilibrium liquid storage box 3 quit work, collapsible joint is retracted, do not affect the rotation of rotating cylinder 2,2 entrys into service of washing machine rotating cylinder utilize the hysteresis quality of liquid flow in the fluid balance ring that unbalance loading is carried out balance.
When unbalance loading larger, when rotating speed is higher, washing machine rotating cylinder 2 suspends, the position sensor of motor makes two of fluid balance ring on the rotating cylinder can aim at the collapsible joint place that is installed in outer barrel in self-packing hole, controller control collapsible joint and fluid balance annular distance are connected, water pump and flowmeter work in the computer program control equilibrium liquid storage box, equilibrium liquid in the equilibrium liquid storage box flows by upper tubing to the fluid balance ring, can calculate equilibrium liquid weight in the fluid balance ring by the flowmeter variable, when weight reaches setting value, water pump and flowmeter in the controller control equilibrium liquid storage box 3 quit work, collapsible joint is retracted, 2 entrys into service of washing machine rotating cylinder.Fluid balance ring 1 inner equilibrium liquid can according to the unbalance loading situation, utilize centrifugal force automatically to regulate distribution opposing unbalance loading.
