Description
Technical field
The present invention relates to the absorption of vibrations damper of automatic washing machine, particularly relate to and can both increase damping force in the both direction corresponding with the compression and expansion of damper, thus the absorption of vibrations damper for automatic washing machine of more stable vibration-damping function is provided.
Background technology
The main body of washing machine supports rotary barrel in the mode of four-point supporting, and is provided with absorption of vibrations damper to absorb and weakens vibration and the impact of rotary barrel, and this is known in the art.
This absorption of vibrations damper is arranged at rotary barrel, to absorb during the washing and dehydration of washed clothes and to reduce vibration and the impact of rotary barrel, keeps rotary barrel by providing support power as suspension simultaneously.
Propose in the art and developed the various absorption of vibrations dampers of automatic washing machine.Such as, in the absorption of vibrations damper of washing machine disclosed in No. 20-0221988th, Korean Utility Model, the upper end of support bar is provided with the support being assembled to main body upper plate, the lower end of support bar is provided with the damping spring being connected to cistern, to be weakened vibration or the impact of rotary barrel generation by the reciprocating motion of damping spring.
Such as, Fig. 5 illustrates traditional absorption of vibrations damper of automatic washing machine.The two ends of support bar 101 are connected respectively to main body and the rotary barrel of washing machine, and are provided with the support 102 that cylinder is connected to main body upper plate (not shown), the spring 105 making the reciprocating slide block 103 of support bar 101 and be flexiblely arranged between the upper spring seat 103a of slide block 103 and lower spring cup 104.
But, in above-mentioned traditional absorption of vibrations damper, because the downside of the upper spring seat 103a of slide block 103 is formed as monomer, and directly contact spring 105, so only have when spring 105 is just applied damping force to support bar 101 by during compression during reciprocating motion, and realize under the state not applying damping force to support bar 101 when spring 105 stretches impacting or vibration reduction and weaken, therefore there is the shortcoming that damping force is deteriorated.
Summary of the invention
The invention solves this problem in this area, the object of this invention is to provide a kind of absorption of vibrations damper for automatic washing machine, it can apply damping force with on the direction being applied to the compression stress of slide block or the corresponding of stretching force during the reciprocating motion of spring, the damping force corresponding with the reduction of vibration & noise is increased, thus realizes stable damp impacts and noise reduction function.
According to the present invention, a kind of absorption of vibrations damper for automatic washing machine comprises: support bar, and the cistern being provided with rotary barrel is connected to main body by it; Support, it is assembled to described support bar and is fixed on the upper plate of described main body; Slide block, it is arranged on below described support; And spring, between its upper spring seat being flexiblely arranged on described slide block and lower spring cup, the upper spring seat of wherein said slide block is formed as cone shape, comprise the radial component split at a predetermined angle relative to support bar through hole, the upper spring seat of described slide block is provided with cover cap, and described spring is flexiblely arranged between described cover cap and described lower spring cup.

Detailed description of the invention
Describe the present invention in detail with reference to the accompanying drawings.
Fig. 1 and Fig. 2 is exploded view according to the absorption of vibrations damper for automatic washing machine of the present invention and constitutional diagram respectively.
Absorption of vibrations damper for automatic washing machine according to the present invention comprises: support bar 1, and the cistern being provided with rotary barrel (not shown) is connected to the upper plate (not shown) of main body by it; Support 2, it is assembled to support bar 1 and is fixed on the upper plate of main body; Slide block 3, it is arranged on below support 2; And spring 5, it is flexiblely arranged between the upper spring seat 3a of slide block 3 and lower spring cup 4, wherein the upper spring seat 3a of slide block 3 has the cone shape comprising the radial component 7 split at a predetermined angle relative to support bar through hole 6, the upper spring seat 3a of slide block 3 is provided with cover cap 8, and spring 5 is flexiblely arranged between cover cap 8 and lower spring cup 4.
At this, with reference to figure 4A and Fig. 4 B, the upper spring seat 3a of cone shape is in middle part cutting groove 9 both sides and be formed with partial cut groove 10 between radial component 7, and wherein partial cut groove 10 diametrically, and be separated from each other the angle (θ) of about 90 degree.Here, it should be noted that the number that can adjust partial cut groove 10 as required and the angle (θ) between them.
The upper spring seat 3a comprising the cone shape of radial component 7 has the diameter of the end pyramidal structure less than the diameter of upper end.
Cover cap 8 is installed to upper spring seat 3a, and surround slide block 3, contact the some place of upper spring seat 3a at housing 8, the internal diameter of housing 8 equals the external diameter of upper spring seat 3a, the annular flange flange 8a of the upper-end contact cover cap 8 of spring 5.
Like this, the spring 5 being assembled to support bar 1 be flexiblely arranged on the end being arranged at support bar 1 lower spring cup 4 and around the cover cap 8 of the upper spring seat 3a of slide block 3 annular flange flange 8a between.
Have in the absorption of vibrations damper of this configuration according to of the present invention, such as when producing impact or vibration at washing machine duration of work, the direction of external pressure arrow X in figure 3 acts on the upside of slide block 3, the radial component 7 being formed at the upper spring seat 3a of slide block 3 draws closer together and Compress Spring 5, between support bar 1 and slide block 3, produce friction simultaneously, thus absorb vibration or external force.
On the other hand, when acting on the upper spring seat 3a of slide block 3 on the direction of external pull arrow Y in figure 3, spring 5 turns back to initial position, and the radial component 7 being formed at the upper spring seat 3a of slide block 3 shrinks and produces friction due to the contact between cover cap 8 and slide block 3 between support bar 1 and slide block 3, thus absorb vibration or impact.
As mentioned above, according to the present invention, spring 5 can with the compression of spring and uphold corresponding both direction absorbs and reduces washing machine washing or dehydrating operations during produce external force, shock and vibration, thus increase damping force and improve the function of decrease of noise functions and damp impacts.
Therefore, the invention provides and a kind ofly can produce with the compression of spring with uphold the damping force that corresponding both direction applies at washing machine duration of work, thus improve damp impacts function and decrease of noise functions.
Although there is described herein some embodiments, it will be understood by those of skill in the art that these embodiments only provide in order to example, and various amendment, change, replacement and equivalent embodiment can be there is when not departing from the scope of the invention.Therefore, scope and spirit of the present invention should only be limited by claims and equivalent thereof.
