In prior art, laundry machine dehydration balance sysmte has following several form:
One is without equilibrium liquid gimbal, and its dehydration centering capacity is poor, easily hits bucket;
Two is without block reinforcement equilibrium liquid gimbal, due to block reinforcement without hindrance in its inner flow passage, when just starting, equilibrium liquid does not have blocks flow too fast, plays reaction on the contrary, easily hits bucket when washing machine has just started dehydration, only reach after running up, because rotating speed is fast, equilibrium liquid flowing is also fast, just can play certain correction effect;
Three is the equilibrium liquid gimbals being provided with one block reinforcement in runner, although it can stop the quick flowing of equilibrium liquid when low rate start, does not hit bucket during startup, and reaching the choked flow effect due to block reinforcement at a high speed, centering capacity is affected;
Four is dual channel gimbals, there are interior side runner and outer side runner two runners, in it, side runner is that wider low speed starts runner, can rectify a deviation well when starting, outside is the high speed runner that section is less, contribute to the correction promoting staving top, enter when running up simultaneously, there is good system centering capacity, but the centering capacity of this version is limited to the size and shape of cross section of fluid channel, if interior side runner cross-sectional area is greater than 2 times of outer side runner, then running in the process entering high speed and can hit bucket, if interior side runner cross-sectional area is less than 1.5 times of outer side runner, then centering capacity is restricted.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, provides a kind of three Runner Balance rings, can ensure good centering capacity when making it at low speed and run up, and can low speed and at a high speed between smooth conversion.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of the present invention three Runner Balance ring is:
On the cross section of the torus shaped cavity of gimbal, circumferentially interval arranges each road dividing plate, described dividing plate arranges three separate overcurrent ducts, place, the center in described three overcurrent ducts, place is divided and is on the different radius of a circle position of described torus shaped cavity, be respectively the high speed runner be on excircle, the low speed runner be on inner periphery, and be in the transition runner between high speed runner and low speed runner; The circulation area of described low speed runner is greater than the flow area of transition runner, and the circulation area of described transition runner is greater than the circulation area of high speed runner;
Described high speed runner is the unimpeded runner not arranging choked flow muscle; Transition runner choked flow muscle is provided with in described transition runner; Low speed runner choked flow muscle is provided with in described low speed runner.
The design feature of the present invention three Runner Balance ring is also:
The height of described transition runner choked flow muscle is 0.3 times of the height of transition runner; The height of described low speed runner choked flow muscle is 0.5 times of low speed runner height.
Described gimbal split is set to the lower semi-ring of semi-ring, and described dividing plate is in first ring with the convex tendon on same circumference position in lower semi-ring to piecing together into by dividing.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention China and foreign countries side runner because of cross-sectional area little, liquid stream momentum is also little, can not on causing too large impact during zero load, and when entering high speed, by dehydration centrifugal forces affect, equilibrium liquid can flow at high speed laterally, because outer side runner is unobstructed, centering capacity can improve greatly; Intermediate flow channel to enter high speed processes from low speed in dehydration barrel and plays certain balanced action, guarantees the stability of balance sysmte in rotating speed transient process; Interior side runner is when low rate start, by the effect of block reinforcement, equilibrium liquid constricted flow, flow velocity can not be too fast, thus equilibrium liquid transition correction causes hitting bucket when avoiding low speed, again because its cross-sectional area is large, also certain centering capacity can be formed upon actuation, thus the centering capacity be lifted at when low strap is transitioned into high speed, particularly reduce and hit a barrel number of times when entering into high speed dewatering from low speed.
Accompanying drawing explanation
Fig. 1 is cross-sectional configuration schematic diagram of the present invention;
Fig. 2 is semi-loop schematic diagram in the present invention;
Fig. 3 is semi-loop schematic diagram under the present invention;
Number in the figure: 1 dividing plate; 2 high speed runners; 3 transition runners; 3a transition runner choked flow muscle; 4 low speed runners; 4a low speed runner choked flow muscle; Semi-ring on 5; Convex tendon on 6; 7 times semi-rings; 8 times convex tendons, 9 gimbals.
Detailed description of the invention
In concrete enforcement, as shown in Figures 2 and 3, gimbal split is set to the lower semi-ring 7 of upper semi-ring 5, dividing plate is by point being in first ring 5 and the upper convex tendon 6 on same circumference position in lower semi-ring with lower convex tendon 8 to piecing together into, forming gimbal 9 with this.
See Fig. 1, in the present embodiment, the version of three Runner Balance rings is:
On the cross section of the torus shaped cavity of gimbal, circumferentially interval arranges each road dividing plate, dividing plate arranges three separate overcurrent ducts, place, the center of three place's flowing holes is divided and is on the different radius of a circle position of torus shaped cavity, be respectively the high speed runner 2 on excircle, the low speed runner 4 be on inner periphery, and be in the transition runner 3 between high speed runner 2 and low speed runner 4; The circulation area of low speed runner 4 is greater than the flow area of transition runner 3, and the circulation area of transition runner 3 is greater than the circulation area of high speed runner 2;
High speed runner 2 is the unimpeded runner not arranging choked flow muscle;
Be provided with transition runner choked flow muscle 3a in transition runner 3, the height of transition runner choked flow muscle 3a is 0.3 times of the height of transition runner 3;
Be provided with low speed runner choked flow muscle 4a in low speed runner 4, the height of low speed runner choked flow muscle 4a is 0.5 times of low speed runner 4 height.
In concrete enforcement, the equilibrium liquid of injection is the volume of 50% of three runner total measurement (volume)s.
Inner side low speed runner 4 is when low rate start, and by the effect of block reinforcement, equilibrium liquid constricted flow, flow velocity can not be too fast, thus when avoiding low speed, equilibrium liquid transition correction causes hitting bucket, and again because its cross-sectional area is large, performance of rectifying a deviation when cold-starting is good.
Middle transition balanced runner 3 to enter high speed processes from low speed in dehydration barrel and plays certain balanced action, guarantees the stability of balance sysmte in rotating speed transient process; Thus the centering capacity be lifted at when low strap is transitioned into high speed, the dehydration barrel particularly reduced when entering into high speed dewatering from low speed clashes into the number of times of outer barrel.
Outside high speed runner 2 because of area of section little, liquid stream momentum is also little, can not cause dewatering system during low rate start and affect from unbalance loading, and when entering high speed, by dehydration centrifugal forces affect, equilibrium liquid meeting flow at high speed, because of the unobstructed muscle of outside high speed runner, equilibrium liquid flowing is fast, and the correction kinetic energy of generation is also large, and centering capacity promotes obviously.
