Fig. 4 is the schematic cross-section according to washing machine of the present invention.
As shown in Figure 4, washing machine 100 comprises the casing 110 that forms outward appearance; Outer bucket 120 is installed on casing 110 and is arranged in wherein storing washing water; Interior bucket 130 is installed on outer bucket 120 and is arranged to be used for accommodating laundry; And suspension 140, be placed in four jiaos of casing 110 and be arranged to the outer bucket 120 of resiliency supported.
The driver element 12 (referring to Fig. 1) of bucket 130 is installed in outer bucket 120 outer surfaces below in being used to drive.Driver element 12 is mounted to the center of departing from outer bucket 120, and is connected to variable part 14 (referring to Fig. 1), and variable part 14 is installed in the core of outer bucket 120 by belt 16 (referring to Fig. 1).
Here, this driver element may be implemented as direct drive motors.This motor can comprise various motors, as induction machine.
Herein, the damping force that will have is installed on ' A ' side greater than the suspension of the damping force of the suspension that is installed in ' B ' side, and outer barrel 120 oblique towards this ' A ' inclination.Therefore, the suspension with less damping force is installed in ' B ' side.In other words, the damping force of suspension that is installed in ' A ' side is different or asymmetric with the damping force of the suspension that is installed in ' B ' side.
Under such structure, outer bucket 120 that the excessive level vibration in the time of preventing owing to washing machine 100 initializations causes and the collision between the casing 110.
To introduce the structure of the suspension 140 that is installed in ' A ' side in more detail below, and the structure of suspension 140 ' that is installed in ' B ' side on ' A ' side opposite, in ' A ' side, the spacing between outer bucket 120 and the casing 110 is narrow.
Fig. 5 is the sectional view according to the suspension of the washing machine of Fig. 4 of first embodiment of the invention, and Fig. 6 is mounted in the perspective view of damping pedestal of the suspension of Fig. 5, and Fig. 7 is the sectional view according to the suspension of Fig. 5 of second embodiment of the invention.
Fig. 5 shows the suspension 140 that is installed in ' A ' side, and in this side, the interval between outer bucket 120 and the casing 110 is narrow.With reference to Fig. 5, suspension 140 comprises: the damper cap 142 that is installed on outer bucket 120; The connecting rod 141 that one end is mounted through damper cap 142; Be installed on the damping spring 143 of damper cap 142; Be installed on the damping pedestal 145 of damper cap 142 1 ends, be provided for the other end of supporting linkage 141 or an end of damping spring 143; And base cover 146, be installed on the lower openings of damper cap 142.For convenience, suspension 140 will be called " first suspension ".
The top of the damper cap 142 of first suspension 140 extends upward as bottleneck, and extends upward part encirclement connecting rod 141.
The through hole 142a that connecting rod 141 forms through damper cap 142 tops is positioned at the inside of damper cap 142.The distal process of through hole 142a is gone into the inside of damper cap 142, constitutes connecting rod support portion 142c thus, and this connecting rod support portion 142c surrounds and supporting linkage 141.
One end of connecting rod 141 is fixed on the connecting rod fixed part 145c of damping pedestal 145.Preferably, connecting rod fixed part 145c is last side-prominent from damping pedestal 145, and has predetermined altitude with supporting linkage 141 stably.
On the outer surface of connecting rod fixed part 145c, be formed with a plurality of protuberance 145d.A plurality of protuberance 145d are forced to insert the interior perimeter surface of damping spring 143, stably support damping spring 143 thus.
The lower end of damping spring 143 is connected the lip-deep protuberance 145d of bar fixed part 145c and supports, and the spring support portion 142b that the upper end of damping spring 143 is formed on damper cap 142 inner surfaces supports.
In the starting stage, just be not provided the state of washings or clothing in the washing machine, preferred, damping spring 143 keeps compressive states, and the damping pedestal 145 that is used to support damping spring 143 is positioned at the inboard of damper cap 142 lower ends.The reason of makeing like this is: in case clothing or washings are put into bucket 130, then damping spring 143 is owing to the weight of clothing or water stretches, and damping pedestal 145 moves to the downside of damper cap 142.Herein, if damping pedestal 145 is positioned at the end of damper cap 142, bucket 130 in then clothing etc. is placed into, and damping pedestal 145 separates fully with damper cap 142.
Herein, damping spring 143 is coil compression springs preferably, but is not limited to this.As damping spring 143, can use any elastic device that elastic-restoring force and setting are used for absorbing or weakening vibration that has.For example, can use rubber parts to connect an end of connecting rod 141 and the connecting rod fixed part 145c of damping pedestal 145.Equally, can use inside to have the rubber column (not shown) of cavity as damping spring 143.
When damping spring 143 was used as elastic device, preferred, that end that connecting rod 141 is arranged in damper cap 142 was arranged on damping spring 143.
Between the most peripheral of the inner surface of damper cap 142 and damping pedestal 145, form small air cleft 150.Produce the damping by friction effect by air cleft 150.
In damping pedestal 145 bottom sides extension spring 148,149 can be installed.Introduce damping pedestal 145 in more detail below in conjunction with accompanying drawing 6.Above damping pedestal 145, form and be connected to the connecting rod fixed part 145c of connecting rod 141 1 ends, and a plurality of protuberance 145d are set on the outer surface of connecting rod fixed part 145c.Integrally formed spring support portion 145e below connecting rod fixed part 145c.Preferably, spring support portion 145e has wide zone, so that fully support damping spring 143.
Herein, skirt section 145f is the thin tubular with predetermined altitude, and forms air cleft 150 between skirt section 145f outer surface and shock-absorbing sleeve 142 inner surfaces.
A plurality of slit 145b are formed at skirt section 145f along short transverse, and extension spring 148 and 149 is installed in the inner surface of skirt section 145f., separate from skirt section 145f with 149 herein, on the inner surface of skirt section 145f, form recessed channel (not shown) or lock pawl 145a in order to prevent extension spring 148.
Because extension spring 148 and 149 is installed to skirt section 145f, its diameter has reduced than initial diameter, so they have elastic-restoring force to return to initial diameter.Because described elastic-restoring force, the edge of damping pedestal 145 extends to the inner surface of damper cap 142.In other words, skirt section 145f is pushed to damper cap 142, stretches so that can expand.Herein, skirt section 145f has big expansion degree of stretching owing to having a plurality of slit 145b.Even by the extension spring 148 and 149 with less elastic-restoring force, skirt section 145f also can stretch to extending out.
Because the lower openings of the damper cap 142 of first suspension 140 is stopped by bottom 146, the viscous damping force that the air in the damper cap 142 produces is very big.When interior bucket 130 was in tempestuously the undue oscillation state, the air row in the damper cap 142 did not go out, and therefore destroys damper cap 142.In order to prevent to destroy damper cap 142, preferably form pore (not shown) at damper cap 142 places.
Therefore, most preferably, first suspension 140 is installed in ' A ' side.
Introduce suspension 140 ' in more detail with reference to Fig. 7 below, its damping force is less than first suspension 140.For convenience, the suspension 140 ' among Fig. 7 will be called " second suspension ".Except locating to be formed with pore 147 at bottom 146 ' to realize damping force less than first suspension 140, second suspension 140 ' is identical with the structure of first suspension 140.In other words, the air in damper cap 142 produces viscous damping force when discharging by the pore 147 of bottom 146 '.Therefore, the damping force of second suspension is less than first suspension 140.
If pore (not shown) is formed on the damper cap 142 of first suspension 140, then must form additional pore (not shown), with the damping force that realizes second suspension 140 ' damping force less than first suspension 140 at damper cap 142 places of second suspension 140 '.
More specifically, the structure of second suspension 140 ' is identical with first suspension 140, except also locating to form pore 147 at bottom 146 '.Pore 147 can be formed on the bottom 146 ' of the damper cap 142 or second suspension 140 '.The pore 147 of damper cap 142 can be stacked on damper cap 142 lip-deep lubricants (as grease) and block, but the possibility of 147 lubricated doses of obstructions of pore of bottom 146 ' is very little.Can also the one or more suspensions of damping force less than second suspension 140 ' be installed at the offside of first suspension 140, they will be called as " the 3rd suspension ".
The 3rd suspension is identical with the structure of first suspension 140 or second suspension 140 ', and bottom 146 and 146 ' therefrom is removed respectively.In other words, the 3rd suspension has damper cap 142, and its downside is opened.But damping pedestal 145 is installed on the 3rd suspension.
Gas can take place and leak in the 3rd suspension by the air cleft 150 between damper cap 142 and the damping pedestal 145.Therefore, the wearing and tearing of control air cleft 150 are very important.For this reason, extension spring 148 and 149 must be played very important effect.To introduce the extension spring 148 and 149 of the 3rd suspension below in more detail.The extension spring structure of first suspension 140 and second suspension 140 ' is identical with the extension spring structure of the 3rd suspension.
Fig. 8 A-8C is a view of representing to be installed in the extension spring on the damping pedestal of Fig. 6 respectively, and Fig. 9 A-9C is the variation instance of the extension spring of Fig. 8.
As shown in Figure 8, the extension spring 148 of the 3rd suspension is the annular with contiguous circumferential.In other words, when when the front is watched, extension spring 148 sub-circulars (referring to Fig. 8 B), but when watching from the side, extension spring 148 has the some parts (referring to Fig. 8 C) that longitudinally overlaps each other.In other words, extension spring 148 is wound in and makes its two ends can have predetermined length to overlap each other.
In extension spring 148, be formed centrally sweep 148a and 148b at the place, two ends of extension spring 148 herein.Bend 148a and 148b are used for extension spring 148 is installed on the damping pedestal 145.As bend 148a and 148b during at the two ends pressurized, the diameter of extension spring 148 1 sides diminishes, and makes extension spring 148 be easy to be installed on damping pedestal 145.Then, when bend 148a and 148b were released, extension spring 148 was returned to original state.Simultaneously, skirt section 145f stretches to extending out.
Shown in Fig. 8 A, owing to have contiguous circumferential, the downside surface of extension spring 148 Continuous Contact damping pedestals 145, i.e. all parts of skirt section 145f, and contact skirt section 145f.Therefore, the air cleft 150 between damper cap 142 and the damping pedestal 145 is kept equably along the circumferencial direction of extension spring 148, therefore the inhomogeneous gap that prevents air cleft 150.
Because employed extension spring 148 has contiguous circumferential, can prevent the flat wearing and tearing of skirt section 145f (flatly abrade) of damping pedestal 145, even when friction takes place the inner surface with damper cap 142.
Fig. 9 A-9C is the variation instance of the extension spring of Fig. 8.
Referring to Fig. 9, except two ends did not have sweep, extension spring 149 was identical with extension spring 148 shapes of Fig. 8.
When the front is watched, extension spring 149 is the annulars (referring to Fig. 9 B) with contiguous circumferential, but when watching from the side, extension spring 149 has the some parts (referring to Fig. 9 C) that longitudinally overlaps each other.Because its lap, the elastic-restoring force of extension spring 149 can keep for a long time, and extension spring can be easy to just be installed on the 145f of skirt section.In other words, in case the user grips extension spring 149 when making its central compression, the diameter of extension spring 149 1 sides reduces, and makes extension spring 149 be easily installed in skirt section 145f.
By using extension spring 148 and 149, the three suspensions can keep air cleft 150 between damper cap 142 and the damping pedestal 145 consistently.Therefore, increased the viscous damping force of the air generation of leaking by air cleft 150.
The 3rd suspension is implemented as and makes damper cap 142 have lower openings, and bottom 145 and 145 ' is not also installed in the there, and therefore the gas that takes place leaks more than first suspension 140 or second suspension 140 '.Therefore, the damping force of the 3rd suspension is less than first suspension 140 or second suspension 140 '.
When installation has the suspension of different damping power, select suitable suspension to be arranged such that the damping force that is centered in outer barrel 120 centers can be asymmetrical relative to one another can from first to the 3rd suspension.
In other words, when adopting first suspension when having big damping force, select second suspension 140 ' or the 3rd suspension as suspension with little damping force.On the contrary, when adopting second suspension 140 ' when having big damping force, select the 3rd suspension as suspension with little damping force.Select in order to carry out these, must consider the load of driver element or mechanical part, or the initial deflection of outer bucket.
Figure 10 is an experimental curve diagram, it has compared excessive level vibration and the vertical vibrating or the amplitude of the present invention and correlation technique, in the present invention, first suspension 140 is installed in ' A ' side and second suspension 140 ' is installed in ' B ' side, uses the suspension that is mutually symmetrical in correlation technique.Referring to Figure 10, horizontal axis is represented the level and the vertical vibrating of outer bucket 120, and initial axis is represented the amplitude (mm) according to vibration.Referring to Figure 10, according to the present invention, first suspension 140 is installed in outer bucket 120 oblique ' A ' sides and second suspension 140 ' is installed in ' B ' side on ' A ' side opposite in the present invention, compare with conventional art, horizontal vibration amplitude of the present invention has increased 1.01mm, but vertically amplitude is reduced to 14.57mm from 19.84mm, has reduced 5.27mm.In other words, when using suspension 140 of the present invention and 140 ', undue oscillation has at utmost reduced 27% of conventional art.
So far, be the application who introduces according to washing machine, but the present invention is not only applicable to washing machine, also is applicable to various fields, for example with the washing machine of Water Extraction Machinery, drying machine compatibility, or with the washing machine of washing system combination.
Equally, introduced in the present invention, outer bucket because the off-centre of motor (for example driver element) is installed to lopsidedness.But, when using direct drive motors, or when the load of driver element or mechanical part is being centered in outside under the situation at bucket center not along the circumferential direction each other fully during symmetry, outward barrel can be to lopsidedness.The latter is also in claim scope of the present invention.
