Abstract
The present invention is one cylinder type double spring shock eliminator for automatic wavy wheel washer with two-in-one casing tub. The shock eliminator consists of two springs including one light load one and one heavy load one; one cylinder with one piston to form one air cavity with air to reduce the high order resonant components, to damp rebound of the springs and to convert the vertical vibration into horizontal swing; and one suspending rope to reduce the effect of the inertial body on the pedestal of the washing machine and to raise the shock eliminating capacity of the washing machine.
Description
Technical field
The present invention relates to a kind of shock absorber, be meant a kind of cylinder type double-spring vibration absorber that is applied in shell bucket unification full-automatic impeller type washing machine especially.
Background technology
Existing air-cylinder type shock absorber is commonly called as " suspension rod ", and (Fig. 3) the You Yi hood-shaped cylinder of Chung and the piston and the bearing spring that are affected by piston rod that are contained in cylinder inner cavity constitute, four " suspension rods " sling the steel ladle of washing machine during use, be suspended on four corners of washing machine shell, in order to eliminate the vibration that produces in the washing machine work.Shell bucket unification full-automatic impeller type washing machine owing to got rid of the shell of conventional washer, unites two into one steel ladle and shell, become the washing machine of a new structure, therefore, design a shock absorber that is suitable for the specific (special) requirements of shell bucket unification automatic washing machine, just carried.
Shell bucket unification full-automatic impeller type washing machine has specific (special) requirements (Fig. 2) because of structural characteristics to keeping away to shake, the inertia system that its vibration source mainly is made up of clothing, dehydration barrel, impeller, motor-driven and arrangement of clutch is suspended on this coasting body to be arranged in by four shock absorbers and alleviates the influence of elimination work coasting body vibration to shell bucket and base on four jiaos of the washing machine pedestal top support frames.
Coasting body has following kinetic characteristic:
A. changes in weight characteristic
Shell bucket unification full-automatic impeller type washing machine has strict restriction because of structural characteristics to the coasting body lifting distance, contradiction be, coasting body can be different in different working stage weight, as can increase the weight of after putting into clothing, can lighten after the water filling (buoyancy), the heaviest before the dehydration after the draining (wet clothing), lighten gradually again after the dehydration (gradually doing), wherein the weight because of buoyancy of water effect coasting body is the lightest after the water filling.Therefore, shock absorber must satisfy the strictness restriction that lifting distance that coasting body causes by the changes in weight of each working stage changes;
B. vibration characteristics
The coasting body of shell bucket unification full-automatic impeller type washing machine is the strongest in the vibration that the dehydration working stage produces, its vibration be clothing by biasing with due to the dehydration barrel high speed rotary motion, be the resultant motion of a kind of collection rotation (dehydration barrel), horizontal hunting (revolution) and vertical vibration; Wherein, coasting body horizontal hunting (revolution) is stabilized in the acceptable limit and with clothes dewatering weight saving and weakens, and the vertical vibration meeting strengthens swing, so the maximum that causes harm because of being subjected to the restriction of gyroscopic effect; Therefore require shock absorber to transfer the horizontal hunting component to the vertical vibration component minimizing of coasting body vibration or with it as far as possible.The present invention takes following measures to reach and keeps away the purpose of shaking for this reason.
Summary of the invention
Keep away the specific (special) requirements of shaking when the present invention is directed to the work of above-mentioned shell bucket unification full-automatic impeller type washing machine, a kind of a kind of cylinder type double-spring vibration absorber that is fit to this class washing machine is provided, reach and make shell bucket unification full-automatic impeller type washing machine keep away the purpose of shaking.
The object of the present invention is achieved like this: a kind of cylinder type double-spring vibration absorber comprises cylinder, piston, underloading spring, heavy-duty springs, soft rope, wherein: described cylinder is that plastics are made the open end that an end opens wide, the outer wall of other end sealing is the sphere end of sphere and center and is provided with through hole, the hood-shaped object of cavity De Chung; Described piston is the bowl-type made of rubber, " bowl " end is porose and be embedded with reinforcing washer, and " bowl " inwall is lined with elasticity support ring, " leather cup " shape thing that external diameter is identical with cylinder bore diameter; Described underloading spring be its external diameter less than cylinder bore diameter, its internal diameter is greater than the compression spring of heavy-duty springs external diameter; Described heavy-duty springs be its external diameter less than the underloading spring inside diameter, its internal diameter is greater than soft rope external diameter, length is less than the compression spring of underloading spring; Described soft rope is the T shape multi-strand steel cord that an end has the cap head; Soft rope is passed piston center hole, pass underloading spring, heavy-duty springs, from the cylinder open end piston, heavy-duty springs, underloading spring are led in the cylinder chamber, the through hole at center passes in the cylinder sphere end chamber again.
Said structure has reached following purpose:
Adopt dual spring
By the underloading spring-loaded, heavy-duty springs adds load-bearing during heavy duty during underloading, guarantees that coasting body can not transfinite or come-up; Experimental results show that because the effect of spring energy-storage, make the elastic force of spring too small and excessive to keep away shake all unfavorable; If adopt the bigger spring of single elastic force, then vertical vibration is strengthened in the underloading stage, if adopt the less spring of single elastic force then when heavy duty coasting body can sink to transfiniting and vertical vibration also can strengthen; And the employing dual spring, when washing enters heavy duty during the stage, coasting body increases the weight of to sink, and heavy-duty springs gets involved load-bearing, has solved that coasting body sinks to transfiniting and heavy duty keeps away the problem of shaking; Along with dehydration is closed on when finishing, the coasting body weight come-up that lightens gradually, heavy-duty springs disengages, and the underloading spring is born separately, has solved the coasting body underloading and has kept away the problem of shaking.
The effect of cylinder piston
Utilize cylinder and piston to enclose the elastic reaction of air in the air chamber, weaken the amplitude of the higher order resonances component of coasting body vibration, therefore, require air chamber to keep air-tightness as far as possible, only allow the through hole joint portion of soft rope and cylinder that small leak is arranged.
Damping action
Suitably improve the tensile force of piston and cylinder wall, the damping action that is produced can the sluggish backward spring resilience time, transfers vertical vibration to horizontal hunting.
The effect of soft rope
Adopt soft cable suspension, can reduce the influence of coasting body vertical vibration to greatest extent, reduce the interference of vertical vibration, make coasting body keep horizontal hunting, improve the ability of shaking of keeping away of complete machine the coasting body gyroscopic effect to washing machine pedestal.
