The specific embodiment
Be described in further detail below in conjunction with the suspension arrangement of the drawings and specific embodiments erect type washing machine of the present invention:
As shown in Figure 3, suspension arrangement according to the present invention includes connecting rod 22, shock absorber cover 24, damping ring the 25, the 1st pendulum spring the 26, the 2nd pendulum spring 27 formations.The upper end of connecting rod 22 is fixed on the outside casing (not shown).Shock absorber cover 24 is fixed on the water butt.Damping ring 25 is formed on connecting rod 22 bottom.The 1st pendulum spring 26 is in damping ring 25 upsides and connecting rod 22 outsides.The 2nd pendulum spring 27 is in the 1st pendulum spring 26 inboards.
In order to limit the position of the 2nd pendulum spring 27, the upper end of the 2nd pendulum spring 27 and lower end have upside fixator 28 and downside fixator 29 separately.In order to promote upside fixator 28, has the fixator extension end 241 that prolongs formation to downside at the middle part of shock absorber cover 24.And the 1st pendulum spring 26 and the 2nd pendulum spring 27 on the periphery energy of connecting rod 22/move freely down.
Below the embodiment of the invention with said structure is described:
Water butt etc. is in light weight during dehydration, and it is little to be applied to the load that shock absorber puts by washtub.So only use also abundant support load of the 1st pendulum spring 26, therefore the vibration that fully transmits during absorption dewatering.
Relative position between the shock absorber cover 24 that is fixed on the connecting rod 22 of casing and is sunk by the weight of water butt etc. changes the free path distance H 1 of not crossing the 2nd pendulum spring 27, so only also can fully absorb vibration with the 1st pendulum spring 26.
As shown in Figure 4, the weight of machinery weight such as washtub and water and washings is applied on the water butt during washing, and the fixed position that therefore is fixed on shock absorber cover 24 and connecting rod 22 on the water butt relatively sinks with sizable amount.At this moment, fixator is hung end 241 and is pushed upside fixator 28, and therefore the 1st pendulum spring 26 and the 2nd pendulum spring 27 apply high coefficient of elasticity, support the big load of elastic force thus.So, also can keep the variable range of pendulum spring 26,27 when washing greatly when loading, can fully absorb the vibration that the outside applies.
As shown in Figure 5, trunnion axis is the whole displacement (being the deflection of water butt) of pendulum spring, and vertical axis is the load that is applied by water butt.The 1st flexure curve 31 of coefficient of elasticity prior art, that be suitable for when dewatering; The 2nd flexure curve 32 of the coefficient of elasticity that all is suitable for when of the present invention, when washing and dehydration; With different in the past, the 3rd flexure curve 33 that coefficient of elasticity is big.
The 1st flexure curve 31, the addendum modification of pendulum spring is in B section and C section when dehydration, and therefore absorption that can be stable is vibrated.But because load is excessive, the maximum addendum modification that the addendum modification of pendulum spring surpasses pendulum spring is the E section during washing, therefore can not absorb vibration, promptly can not vibration damping.
The 3rd flexure curve 33, the coefficient of elasticity of pendulum spring is fully big, and the addendum modification of pendulum spring also in C section and D section, therefore can fully absorb vibration under the big gravity that applies during washing.But when dehydration be because in light weight, and the addendum modification of pendulum spring is without B section and C section, therefore can not fully absorb vibration but pass to the outside.
Therefore the rigidity of pendulum spring is excessive, and its displacement amplitude diminishes, and the vibration that causes of little impact directly is sent to the outside, can not absorb on suspension arrangement.
According to the 2nd flexure curve 32 of present embodiment, have only the 1st pendulum spring 26 during dehydration in work, therefore also can possess wide displacement amplitude (B section and C section), and can fully absorb its vibration for little load.And therefore the 1st pendulum spring 26 and the 2nd all displacements of pendulum spring 27 during washing can be to support the load that applies in the D section in the displacement scope of pendulum spring.So washing and when dehydration, can both be in certain displacement scope the load on the support spring neatly.
When the load that applies during washing was big, in order fully to support gravity, the coefficient of elasticity of the 2nd pendulum spring 27 should be bigger than the coefficient of elasticity of the 1st pendulum spring 26.As shown in Figure 4, fixator is hung end 241 lower end positions and is decided by the length of the 1st pendulum spring 26 and the 2nd pendulum spring 27 etc., and the position of the 1st pendulum spring 26 maximum displacements of the peak load that applies when dehydration is leaned on a little and formed fixator on some positions and hang and hold.
Possess 2 pendulum springs 26,27 in the present embodiment, also be suitable for but two above pendulum springs that the total weight according to washtub, washings and water operates separately are installed in same structure.
An alternative embodiment of the invention as shown in Figure 6, and is most of same as the previously described embodiments, just increases the pad 41 of resin material on the outer peripheral face of the damping ring that causes damping effect.Therefore when washtub transmits vibration, make pad 41 outer peripheral faces overlap 24 inner peripheral surfaces and contact, increase frictional force and obtain better effectiveness in vibration suppression with shock absorber.
Pad 41 is made by resin material, makes it produce soft frictional force.
If thought of the present invention is applied in about the impeller/the vibration washing machine of the raising detersive efficiency that the whole direction in the left and right sides is rotated on, more can improve damping efficiency.
Thought of the present invention does not limit in the above-described embodiments, and its protection domain is as the criterion with claim.
