As an example of supporting member 7, frcition damper can be enumerated.Certainly, as supporting member 7, damper known in the others such as hydraulic damper can be used.Supporting member 7 in the case where frcition damper includes the hollow shell 29 toward the lower end of the bar 28 and receiving bar 28 that slenderly linearly extend up and down.Referring to the major part of supporting member 7 and its schematic vertical sectional figure, that is, Fig. 2 of peripheral portion, supporting member 7 includes
The biasing members 31 such as the discoid damper member 30 linked in shell 29 with the lower end of bar 28 and the helical spring being configured in shell 29.Bar 28 can be relatively moved relative to shell 29, and by the relative movement, supporting member 7 is whole scalable.Further, since biasing member 31 exerts a force to damper member 30 to downside Z2 in shell 29, therefore 7 entirety of supporting member can elastic telescopic.
It referring to left side schematic elevational view, that is, Fig. 3 of the major part of washing machine 100, links with bar 28, lateral strut 13 is all provided with a linking part 32 in front part 13A and rear section 13C one by one on the upside of the pair of right and left of outline border 10 (also referring to Fig. 1).In other words, total there are four for linking part 32.Each linking part 32 is formed as metal plate thin on up and down direction Z.Linking part 32 can be both integrally provided with upside lateral strut 13, be can also be used as individual member by screw etc. and be fixed on upside lateral strut 13.Be set to left side X1 upside lateral strut 13 linking part 32 by from the upside lateral strut 13 towards washing tube 2 to the right X2 it is outstanding in a manner of configure.Be set to right side X2 upside lateral strut 13 linking part 32 (not shown) by from the upside lateral strut 13 towards the X1 to the left of washing tube 2 it is outstanding in a manner of configure.In each upside lateral strut 13, the linking part 32 for being set to front part 13A is known as front side linking part 32A, the linking part 32 for being set to rear section 13C is known as rear side linking part 32B (also referring to Fig. 1).In each linking part 32, it is formed with the through hole 32C along up and down direction Z perforation linking part 32.Be formed as narrowing spherical with towards downside Z2 in the inner peripheral surface 32D that linking part 32 marks off through hole 32C.
In the upper end of bar 28, it is provided with the hemispherical upside holding section 28A to downside Z2 bulging.The upside holding section 28A of each front side supporting member 7A is embedded in the through hole 32C of front side linking part 32A co-located on X in left and right directions from upside Z1, as a result, in the state engaged from upside Z1 with front side linking part 32A.The upside holding section 28A of each rear side supporting member 7B is embedded in the through hole 32C of rear side linking part 32B co-located on X in left and right directions from upside Z1, as a result, in the state engaged from upside Z1 with rear side linking part 32B.Each upside holding section 28A is in the state with the inner peripheral surface 32D sphere-contact for marking off through hole 32C on linking part 32.
Shell 29 is formed as the substantially cylindrical shape that its long side is in the longitudinal direction of bar 28.The upper end of shell 29 is used as downside holding section 29A, is formed as to the hemispherical of upside Z1 bulging.Bar 28 is in the upper end 29B of downside holding section 29A up and down and to upside Z1 state outstanding.The downside holding section 29A of each front side supporting member 7A is embedded in the accommodating space 21 of front side receiving portion 18A co-located on X in left and right directions from downside Z2, as a result, in the state engaged from downside Z2 with the holding section 20 of front side receiving portion 18A.The downside holding section 29A of each rear side supporting member 7B is embedded on X in left and right directions from downside Z2
The accommodating space 21 of co-located rear side receiving portion 18B, as a result, in the state engaged from downside Z2 with the holding section 20 of rear side receiving portion 18B.In this way, four receiving portions 18 are installed on the downside holding section 29A positioned at the lower part of each supporting member 7 one by one.It should be noted that bar 28 passes through the gap 18D of receiving portion 18 when downside holding section 29A to be embedded in accommodating space 21.
In each supporting member 7, downside holding section 29A is in the state with inner peripheral surface 20A (referring to Fig. 2) sphere-contact for marking off accommodating space 21 on holding section 20, and bar 28 is in from the through hole 18C of the upper end of receiving portion 18 to upside Z1 state outstanding.Bar 28 both can be configured to also can be configured to along the vertically extending posture of up and down direction Z relative to up and down direction Z-direction left and right directions X, the inclined posture of front-rear direction Y.In the present embodiment, the bar 28 of front side supporting member 7A is arranged obliquely in a manner of being more directed towards upside Z1 and deviateing to front side Y1, and the bar 28 of rear side supporting member 7B is arranged obliquely in a manner of being more directed towards upside Z1 and deviateing to rear side Y2.
Each supporting member 7 is in the state suspended in midair from the linking part 32 for the upside lateral strut 13 for being set to outline border 10 (also referring to Fig. 1).Downside holding section 29A positioned at the shell 29 of the lower end of supporting member 7 is linked by receiving portion 18 and the outer barrel 3 of washing tube 2.Due to each supporting member 7 can elastic telescopic, four supporting members 7 are in washing tube 2 and are fixed on the motor 5 of outer barrel 3 and the suspention of transmission mechanism 6 carries out the state of elastic bearing (also referring to Fig. 1).Therefore, the vibration that washing tube 2 can be inhibited to generate in washing operating with the rotation of interior bucket 4 is transmitted to casing 1 via linking part 32.
Furthermore, for each supporting member 7, since lower end of the damper member 30 when supporting member 7 is stretched with bar 28 moves together, and it rubs at this moment with the inner peripheral surface 29C of shell 29 (referring to Fig. 2), therefore frictional force can be generated between damper member 30 and the inner peripheral surface 29C of shell 29.By the frictional force, vibration caused by washing tube 2 is weakened.As described above due to each supporting member 7, the state of 20 sphere-contact of holding section in upside holding section 28A and 32 sphere-contact of linking part and downside holding section 29A and receiving portion 18, therefore supporting member 7 can freely convert the inclination relative to up and down direction Z in a manner of the obsessive power caused by make because of the vibration of washing tube 2 do not act on supporting member 7 itself, casing 1.
Four receiving portions 18 are all configured at sustained height position, in particular, four respective through hole 18C of receiving portion 18 are co-located on Z in above-below direction.Therefore, the shell 29 of the accommodating space 21 from downside Z2 insertion receiving portion 18 of four supporting members 7 is configured at same position on Z in above-below direction.Specifically, the upper end 29B that exposes of the slave through hole 18C of the downside holding section 29A of the shell 29 of four supporting members 7 is configured at same position on Z in above-below direction.
On the other hand, in four linking parts 32 that the upside lateral strut 13 of casing 1 engages with the upside holding section 28A for engaging supporting member 7, the front side linking part 32A for being set to front part 13A is located at the position lower than rear side linking part 32B, wherein, rear side linking part 32B is set to the rear section 13C positioned at the position higher than front part 13A (also referring to Fig. 1).In this case, in four supporting members 7, length is identical each other by a pair of of front side supporting member 7A with the upside holding section 28A engaged with front side linking part 32A, with length is identical each other with supporting member 7B on rear side of the another pair for the upside holding section 28A that rear side linking part 32B engages.But a pair of of front side supporting member 7A is different from a pair of of rear side supporting member 7B length, strictly speaking, front side supporting member 7A is shorter than rear side supporting member 7B.It should be noted that, the length of supporting member 7 herein refers to, in one example, in the state that the operating of washing machine 100 stops, the upper end 29B of upside holding section 28A and the lower surface consistent part 28B and downside holding section 29A of linking part 32 are linked and extended along bar 28 the length of line segment L.The length of line segment L namely each supporting member 7 slave receiving portion 18 to the part of the range of linking part 32, in other words namely the length of the part for having positive effect for damping vibration of supporting member 7.Certainly, as another example, the overall length of the overall length of bar 28, supporting member 7 can also be defined as to the length of supporting member 7.
Fig. 4 is the figure of the relationship of the amplitude for the vibration for indicating that the outer barrel 3 of washing tube 2 in dehydration is generated with the rotation of interior bucket 4 and the length difference of front side supporting member 7A and rear side supporting member 7B.Fig. 5 is to indicate outer barrel 3 with the figure of the relationship of the amplitude for the vibration that rotation of the interior bucket 4 at the end of dehydration stops and generates and the length difference of front side supporting member 7A and rear side supporting member 7B.In Fig. 4 and Fig. 5 horizontal axis all indicate front side supporting member 7A it is shorter than rear side supporting member 7B in the case where front side supporting member 7A and rear side supporting member 7B length difference.On the other hand, the amplitude of the vibration generated in the rotary course of the interior bucket 4 of the longitudinal axis expression outer barrel 3 of Fig. 4 during the dehydration process, the amplitude for the vibration that the longitudinal axis expression outer barrel 3 of Fig. 5 is generated when interior bucket 4 is applied braking as dehydration terminates to stop rotating.The unit of length difference and amplitude is, for example, mm.
The braking carried out as the rotation to interior bucket 4, it both can be by the control duty ratio (not shown) that is set to the control unit of washing machine 100, make the quick emergency stop of the rotation of motor 5, in addition brake apparatus (not shown) can also be set and brake apparatus movement is made to make the rotation emergency stop of motor 5 by control unit.
When four receiving portions 18 using the lower end for receiving supporting member 7 are all configured at the structure of sustained height position, as shown in Figure 4, even if front side supporting member 7A and the length difference of rear side supporting member 7B become larger, the amplitude of the vibration in the rotary course of the interior bucket 4 of outer barrel 3 during the dehydration process also hardly happens variation.
On the other hand, as shown in figure 5, outer barrel 3 becomes smaller with the amplitude of the vibration generated when interior bucket 4 is stopped rotating because of braking when the length difference of current side support member 7A and rear side supporting member 7B becomes larger.In other words, it is believed that the vibration that outer barrel 3 generates due to the rotation of interior bucket 4 stops effectively being weakened due to the length difference of front side supporting member 7A and rear side supporting member 7B.
Therefore, when different from supporting member 7B length on rear side of another pair using a pair of of front side supporting member 7A and four receiving portions 18 all configuration sections are when the structure of sustained height position, even if interior bucket 4 just applies the rotation of interior bucket 4 and brake to stop dehydration when rotated during the dehydration process, the vibration of outer barrel 3 can be also effectively inhibited by four supporting members 7.It can inhibit the phenomenon that the outer barrel 3 of the washing tube 2 in casing 1 occurs vibration and collides generation with casing 1 as a result,.
Fig. 6 is the left view of the washing machine 100 of variation.In Fig. 6, to in FIG. 1 to FIG. 3 it is stated that the identical part in part assign identical label, and omit the explanation about the part.For the washing machine 100 illustrated in FIG. 1 to FIG. 3, the longitudinal configuration always of washing tube 2, but for the washing machine of variation shown in fig. 6 100, the posture of washing tube 2 can be changed.
