It is linked to 5 slave shell-side linking part 6 of each supporting member suspention of casing side linking part 6 and barrel side linking part 15, in the state by upper and lower elastic telescopic elastic bearing washing tube 3.Therefore, the vibration caused by washing tube 3 of the rotation in washing operating with interior bucket 11 is inhibited to pass to casing 2 by the flexible of each supporting member 5.
Then, the washing machine of comparative example 51 is illustrated.Fig. 3 is the side view of the major part of washing machine 51 from side.Washing machine 51 includes the casing 52 for constituting the box-like of its shell.With consistent four positions in the quadrangle of casing 52 in the upper end 52A of the inside of casing 52, it is respectively formed with the casing side linking part 52B to downside Z2 recess hemispherical.The through hole 52C that Z extends in above-below direction is formed in the lower end of each casing side linking part 52B.
In the region of the downside Z2 of upper end 52A in casing 52, it is configured with washing tube 53, motor 54 and supporting member 55.Washing tube 53 includes outer barrel 56 and interior bucket 57.In Fig. 3, as locally indicating such as outer barrel 56 and the respective vertical section of interior bucket 57, the part of washing tube 53 is cut open to be illustrated.Outer barrel 56 is formed to have the bottomed cylindrical for the central axis that Z extends in above-below direction.With four positions on the consistent circumference in the quadrangle of casing 52 in the lower end of the circumferential wall of outer barrel 56, it is each provided with the barrel side linking part 56A to upside Z1 recess hemispherical.The through hole 56B that Z extends in above-below direction is formed in the upper end of each barrel side linking part 56A.Interior bucket 57 is, for example, made of metal, is formed as the bottomed cylindrical enclosed than outer barrel 56 small one, is contained in coaxial in outer barrel 56.The identical balance ring 58 with above-mentioned balance ring 18 (referring to Fig.1) is equipped in the upper end of interior bucket 57.Motor 54 is fixed from downside Z2 relative to the bottom wall of outer barrel 56.Interior bucket 57 is driven to rotate and being passed the driving force of motor 54.
Supporting member 55 respectively configures one in the quadrangle of casing 2.Each supporting member 55 is being formed as long up and down
Size it is rodlike.Supporting member 55 includes top 59, lower part 60, force section 61 and attenuator 62.Also referring to Fig. 4 of the profilograph of the major part as supporting member 55, top 59 includes: bar 63, upper and lower elongated and linearly extension;Upside holding section 64 is formed towards the upper end that is hemispherical and being fixed on bar 63 of downside Z2 expansion;Disk-shaped piston 65, is assemblied in the lower end of bar 63.Piston 65 is formed by elastomers such as rubber.It is provided with a pair of of washer 66 in the lower end of bar 63, to be fixed on bar 63 from the state for clamping piston 65 up and down;And cricoid receiving portion 67, positioned at the upside Z1 of washer 66.Each washer 66 and the outer diameter of receiving portion 67 are less than the outer diameter of piston 65.The cricoid slot 67A for surrounding bar 63 is formed in the upper surface of receiving portion 67.
Lower part 60 includes, and the hollow housing section 68 of upper and lower long size and blocks the cover 69 in housing section 68 from downside Z2.Lower end, piston 65, washer 66 and the receiving portion 67 of bar 63 are accommodated in housing section 68.The upper end of housing section 68 constitutes the hemispherical downside holding section 68A for being formed towards upside Z1 expansion.In downside holding section, 68A is formed with the through hole 68B being connected to in lower part 60.The upside Z1 for partially passing through through hole 68B and being configured at downside holding section 68A of the upside Z1 of lower end in bar 63.In this state, top 59 Z can mutually relatively move in above-below direction with lower part 60, and the entirety of supporting member 55 is stretched up and down with the relative movement.In downside holding section, 68A, which is provided integrally in lower part 60, surrounds through hole 68B and to the protruding portion 68C of downside Z2 tubular outstanding.Cover 69 can be the other parts separated with housing section 68, can also be integrally formed with housing section 68.
Force section 61 is for example to be configured in housing section 68 in the helical spring of upper and lower long size with compressed state.The lower end of force section 61 is embedded in the slot 67A for being fixed on the receiving portion 67 of the lower end of bar 63, and the upper end of force section 61 is fitted into the protruding portion 68C of the downside holding section 68A of lower part 60.Compressed force section 61 exerts a force to receiving portion 67 to downside Z2 due to wanting elongation.As a result, due to the top 59 comprising receiving portion 67 it is whole by relative to lower part 60 to downside Z2 relative movement in a manner of being exerted a force, so, supporting member 55 generally in the state to be exerted a force always in a manner of Z elastic shrinkage in above-below direction.
Related to attenuator 62, supporting member 55 is frcition damper.Roughly same outer diameter with piston 65 for the internal diameter of the part of the downside Z2 of downside holding section 68A in the housing section 68 of lower part 60, and the outer peripheral surface of piston 65 and the inner peripheral surface of housing section 68 constitute attenuator 62.When top 59 and lower part 60 relatively move for the flexible of supporting member 55, the outer peripheral surface of piston 65 is mutually slided with the inner peripheral surface of housing section 68.It rubs and decays caused by top 59 and the sliding of the relative movement reason of lower part 60.
In each supporting member 55, the upside holding section 64 on top 59 is embedded in the upper end of casing 52 from upside Z1
Corresponding casing side linking part 52B in portion 52A, in the state with casing side linking part 52B sphere-contact.The through hole 52C of casing side linking part 52B is passed through in the bar 63 that upper end is fixed with upside holding section 64 in top 59 and is configured to downside Z2.In each supporting member 55, the downside holding section 68A of lower part 60 corresponding barrel side linking part 56A from downside Z2 insertion outer barrel 56, in the state with barrel side linking part 56A sphere-contact.Bar 63 is configured across the through hole 56B of barrel side linking part 56A to upside Z1.
55 slave shell-side linking part 52B of each supporting member in washing machine 51 with casing side linking part 52B and barrel side linking part 56A connection suspends in midair, in the state by upper and lower elastic telescopic elastic bearing washing tube 53.Therefore, by the flexible inhibition washing operating of each supporting member 55 as the rotation of interior bucket 57 vibration caused by washing tube 53 passes to casing 52.
Fig. 5 is the washing machine 51 for indicating washing machine 1 and comparative example about first embodiment, the chart vibrated with the relationship by the time generated in the dehydration of each washing machine with the rotation of interior bucket and in washing tube.In Fig. 5, horizontal axis indicates that interior bucket when the revolving speed high speed rotation of such as 1300rpm or more in dehydration to pass through the time, and the longitudinal axis indicates caused by the vibration of the washing tube 3 of the washing machine 1 in the high speed rotation of interior bucket or the washing tube 53 of washing machine 51 to the displacement of lateral XY.Unit by the time is, for example, ms, and the unit of displacement is, for example, mm.
In comparative example, each supporting member 55 only exists in the state for being hooked in casing side linking part 52B and barrel side linking part 56A (referring to Fig. 3).In this case, when deflection is configured with 57 high speed rotation during the dehydration process of interior bucket of washings, the flexible movement for becoming that the washing tube 53 that vibration increases with high speed rotation can not be followed of supporting member 55, supporting member 55 can probably separate moment with casing side linking part 52B and barrel side linking part 56A as a result,.When supporting member 55 is separated with casing side linking part 52B and barrel side linking part 56A, the state that moment becomes free washing tube 53 becomes irregularly, can generate abnormal vibrations in washing tube 53 as a result,.When the liquid in balance ring 58 is biased to the washings side in interior bucket 57 because of the abnormal vibrations of washing tube 53, abnormal vibrations be will increase.Thus, as shown in phantom in Figure 5, the vibration of washing tube 53 is further increased because of the influence of abnormal vibrations, and the amplitude of the vibration of washing tube 53 becomes larger, and the upper limit value and lower limit value of the displacement of the washing tube 53 once vibrated are unstable, and vibration all can significantly change every time.As a result, noise can be generated because of the outer barrel 56 of washing tube 53 and the contact due to of casing 52.In addition, generated contact sound can also become noise when contacting again with them with casing side linking part 52B and barrel side linking part the 56A supporting member 55 separated.
On the other hand, in the washing machine of first embodiment 1, in supporting member 5, top 20 is via upper
Elastomer 40 elasticity in side is linked to casing side linking part 6, and lower part 21 is linked to barrel side linking part 15 via 41 elasticity of downside elastomer (referring to Fig. 2).Therefore, in the high speed rotation of the interior bucket 11 of washing tube 3, even if the power for generating vibration caused by reason high speed rotation and keeping supporting member 5 isolated with casing side linking part 6 and barrel side linking part 15, the power can also be absorbed by the flexible deformation of upside elastomer 40, downside elastomer 41.As a result, since supporting member 5 can be inhibited to separate with casing side linking part 6 and barrel side linking part 15, supporting member 5 can reliably follow the movement of the washing tube 3 along with vibration.Thus, abnormal vibrations since the washing tube 3 caused by being separated by supporting member 5 with casing side linking part 6 and barrel side linking part 15 can be inhibited, therefore, as shown by the solid line in FIG 5, the upper limit value of the displacement of washing tube 3 and lower limit value are approximately fixed and vibrated with the amplitude stability significantly less than comparative example.So the noise as caused by the abnormal vibrations can be inhibited in the washing machine 1 of first embodiment.
In particular, in the washing machine 1 of first embodiment, be set to the top 20 of supporting member 5 upside sandwich portion 27 will be from a pair of of upside elastomer 40 of casing side linking part 6 be clamped up and down from clamping up and down and be fixed on casing side linking part 6 (referring to Fig. 2).The top 20 that supporting member 5 can be further suppressed as a result, is separated with casing side linking part 6.Therefore, the abnormal vibrations of the washing tube 3 caused by being separated by supporting member 5 with casing side linking part 6 can be further suppressed.Further, since the swing with casing side linking part 6 for the washing tube 3 of fulcrum decays because of the flexible deformation of upside elastomer 40, and therefore, the abnormal vibrations of the washing tube 3 caused by capable of also inhibiting by the swing.
Moreover, in the washing machine 1 of first embodiment, be set to the lower part 21 of supporting member 5 downside sandwich portion 32 will be from a pair of lower elastomer 41 of barrel side linking part 15 be clamped up and down from clamping up and down and be fixed on barrel side linking part 15 (referring to Fig. 2).The lower part 21 that supporting member 5 can be further suppressed as a result, is separated with barrel side linking part 15.Therefore, the abnormal vibrations of the washing tube 3 caused by being separated by supporting member 5 with barrel side linking part 15 can be further suppressed.Further, since the swing with barrel side linking part 15 for the washing tube 3 of fulcrum decays because of the flexible deformation of downside elastomer 41, and therefore, the abnormal vibrations of the washing tube 3 caused by capable of also inhibiting by the swing.
It should be noted that, in washing machine 1, although the equal elasticity of preferably all of four supporting members 5 is linked to casing side linking part 6 and barrel side linking part 15, but even the structure of casing side linking part 6 and barrel side linking part 15 is linked to across opposed at least two supporting members, 5 elasticity of washing tube 3, can also inhibit the abnormal vibrations of washing tube 3 to a certain extent.
Then, second embodiment is illustrated.Fig. 6 is the laundry of the second embodiment from side
The side view of the major part of machine 1.In Fig. 6, identical appended drawing reference is assigned to part identical with the part illustrated before and omits the explanation to the part.Fig. 7 indicates about first embodiment and second embodiment, in dehydration with the rotation of interior bucket the figure of the vibration caused by washing tube and the relationship by the time.Chart in Fig. 7 check mode and the chart in Fig. 5 check that mode is identical.
The barrel side linking part 15 that the lower part 21 of supporting member 5 is linked in washing tube 3 can also be as second embodiment, positioned at the downside Z2 of the center of gravity G of washing tube 3.In first embodiment and second embodiment, the bottom wall 13 of outer barrel 10 is fixed on structurally in the motor 4 as weight object, center of gravity G is respectively positioned on the position that downside Z2 is biased in washing tube 3.In the case where washings Z2 on the downside of being biased in interior bucket 11, since Z washings becomes close to center of gravity G in above-below direction, even if the posture of washing tube 3 is also stable during the dehydration process in the case where 11 high speed rotation of interior bucket.
But on the upside of washings is biased in interior bucket 11 in the case where Z1, in second embodiment, due to washings to upside Z1 far from center of gravity G, the posture of washing tube 3 becomes unstable.So the part of the upside Z1 of barrel side linking part 15 is that fulcrum is swung with barrel side linking part 15 in washing tube 3, the abnormal vibrations caused by generating by the swing in 11 high speed rotation of interior bucket.In this way, which as shown in phantom in Figure 7, the upper limit value and lower limit value of the displacement of the washing tube 3 generated by vibration are changed as first embodiment (solid line of Fig. 7) astatically.
On the other hand, in the washing machine 1 of first embodiment, barrel side linking part 15 due to being linked with the lower part 21 of supporting member 5 is located at the upside Z1 of the center of gravity G of washing tube 3, therefore, heavier in washing tube 3 to be partially in from the lower part of supporting member 5 21 to downside Z2 sagging state (referring to Fig.1).In this case, in the state of being configured in the interior bucket 11 of washing tube 3 to Z1 on the upside of washings deviation, even if the part of the upside Z1 of barrel side linking part 15 can be with barrel side linking part 15 for branch spot wobble in washing tube 3, which can also decay because of the downside elastomer 41 of barrel side linking part 15.Abnormal vibrations caused by capable of inhibiting by the swing as a result,.Therefore, as described above, washing tube 53 is vibrated with the lesser amplitude stability of the upper limit value of displacement and the equal constant of lower limit value.Since the washings of Z1 on the upside of being biased in interior bucket 11 reaches near balance ring 18, positioned at center of gravity G upside Z1 15 preferred disposition of barrel side linking part in the height and position adjacent from downside Z2 and balance ring 18.
Then, third embodiment is illustrated.Fig. 8 is the side view of the peripheral part in the vertical section and supporting member 5 of supporting member 5 from the washing machine 1 of third embodiment from side.In fig. 8, identical appended drawing reference is assigned to part identical with the part illustrated before and omit the explanation to the part.
In first and second embodiment, mainly help the abnormal vibrations for inhibiting washing tube 3 in a pair of of upside elastomer 40 and downside elastomer 41 is in supporting member 5 positioned at the second upside elastomer 40B and the second downside elastomer 41B at the both ends of load centralization.
Accordingly it is also possible to omit the first upside elastomer 40A and the first downside elastomer 41A as third embodiment.Washing machine 1 shown in Fig. 8 be equivalent to from first embodiment the first upside elastomer 40A and the first downside elastomer 41A is omitted after structure, although be not so good as first embodiment, can but inhibit the abnormal vibrations of washing tube 3 to a certain extent.Certainly, the reduction of parts count and cost is sought by completing upside elastomer 40 and downside elastomer 41 one by one.
In the washing machine 1 of first~third embodiment, supporting member 5 is oil damper.When the supporting member 5 is flexible for elastic bearing washing tube 3, the piston 26 of 5 middle and upper part 20 of supporting member and the canister portion 30 of lower part 21 are mutually slided.Especially, when 11 high speed rotation of interior bucket during the dehydration process, although piston 26 is small reciprocal to be carried out at high speed in roughly the same position, these pistons 26 and canister portion 30 are made of metal, and the slipper of piston 26 and canister portion 30 is lubricated by the oil of surrounding.Therefore, these slippers are not easy to wear because of sliding.In addition, metal piston 26 and canister portion 30 are difficult to deform because from the lateral load of lateral XY.Even apply lateral load to supporting member 5 in the high speed rotation of interior bucket 11 as a result, the durability and fade performance of supporting member 5 are also ensured that.Therefore, because supporting member 5 is with stable state elastic bearing washing tube 3, thus it is possible to the abnormal vibrations of stabilization checking washing tube 3.
Then, the 4th embodiment is illustrated.Fig. 9 is the profilograph of the major part of the supporting member 5 of the 4th embodiment.Above-mentioned frcition damper can also be used for supporting member 5 to replace oil damper.Therefore, the supporting member 5 of the 4th embodiment has the substantially identical structure with the supporting member of comparative example 55 (referring to Fig. 4).In Fig. 9, identical appended drawing reference is assigned to part identical with the part illustrated in comparative example and omits the explanation to the part.In the fourth embodiment, same as first~third embodiment, the top 59 of supporting member 5 links via upside elastomeric resilient to be linked and barrel side linking part 15 with the lower part 60 with casing side linking part 6, supporting member 5 via 41 elasticity of downside elastomer.Specifically, the upper end of bar 63 and casing side linking part 6 link on top 59, in lower part 60, the lower end of another bar 70 extended from cover 69 to downside Z2 and barrel side linking part 15 link.
Same as the supporting member 5 of first~third embodiment in the supporting member 5 of the 4th embodiment, force section 61 and attenuator 62 are set to the middle part of the supporting member 5 of up and down direction Z.
In four embodiments, even with the supporting member 5 of frcition damper, it can also inhibit the abnormal vibrations of washing tube 3 to a certain extent.In addition, being used for supporting member 5 by will construct frcition damper simpler than oil damper seeks the reduction of cost.
The present invention is not limited to the implementation described above, can make various changes in the range of claim is recorded.
Although central axis J can also obliquely be configured relative to up and down direction Z for example, washing machine 1 is the central axis J longitudinal type washing machine that Z extends in above-below direction as the rotary shaft of interior bucket 11.
In addition, the upper and lower direction of supporting member 5 can also be in turn in the above-mentioned first~the 4th embodiment.In this case, in supporting member 5, above-mentioned top 20,59 (referring to Fig. 2 and Fig. 9) becomes lower part, and above-mentioned lower part 21,60 (referring to Fig. 2 and Fig. 9) becomes top.
In addition, supporting member 5 can not also be exerted a force in a manner of contraction, but exerted a force in elongated manner.
