The upside in the first friction portion 120.Water jacket supporting part 110 may include the first resettlement section S1 for housing the first friction means 120
The second resettlement section S2 in the second friction portion 130 is housed with being formed on the upside of the first resettlement section S1.
First friction portion 120 can be configured in a manner of being fixed relative to water jacket supporting part 110.In the case, it is actual
Upper first resettlement section S1 above-below direction length is identical with the above-below direction length in the first friction portion 120.
First resettlement section S1 and the second resettlement section S2 can be formed at the resettlement section body of the downside extension to placement section 112
113.Resettlement section body 113 is located at the inner side of elastomeric element 150.Resettlement section body 113 may include the bottom with placement section segmentation
At least one side surface part 113a, 113b between 113d and connection placement section 112 and bottom 113d.Resettlement section body 113 so that
The mode that first friction portion 120 or the second friction portion 130 are easily inserted in resettlement section S1, S2 has to side direction opening at least
One side direction opening portion 116,117, in the present embodiment, formed between first side portion 113a and second side portion 113b
There are a pair of first side direction opening portions 116 being connected with the inside of the first resettlement section S1 and the inner side phase with the second resettlement section S2
A pair of second side direction opening portions 117 of connection.First side direction opening portion 116 and the second side direction opening portion 117 are by dividing plate
113c is distinguished.Side direction opening portion 116,117 not only provides the setting in friction portion 120,130 and the easiness of separation, but also
Exercise the function of releasing from heat produced by friction portion 120,130.Also, can be by side direction opening portion 116,117 come straight
Connect to friction portion 120,130 and inject lubricant, so as to provide the convenience of maintenance.
Dividing plate 113c is between the bottom surface of placement section 112 and bottom 113d to the upper and lower sky distinguished in resettlement section body 113
Between.On the basis of dividing plate 113c, the first resettlement section S1 is the bottom of resettlement section body 113, and the second resettlement section S2 is resettlement section sheet
The top of body 113.Dividing plate 113c can be connected between first side portion 113a and second side portion 113b.
In fact, in the first resettlement section S1, the distance between bottom surface 113d and dividing plate 113c and the first friction portion 130
The length of above-below direction is identical, and therefore, the first friction portion 120 is configured in a manner of being fixed relative to the first resettlement section S1, and
Moved in vibration processes in a manner of being formed and being integrated with water jacket supporting part.
Second resettlement section S2 can allow water jacket supporting part 110 to be subjected to displacement relative to the second friction portion 130.That is,
In two resettlement section S2, it is more than the length of the above-below direction in the second friction portion 130 to dividing plate 113c distance from placement section 112, from
And and the corresponding section of difference of length in, water jacket supporting part 110 can be moved with the state separated from the second friction portion 130
It is dynamic.
When the friction portion 130 of water jacket supporting part 110 and second together moves, the second resettlement section S2 can with the second friction portion
130 regions for producing contact form projection 118a, 118b.In more detail, placement section 113 can be downward from the bottom surface of placement section 112
Side direction includes the upper lateral process 118a prominent to the second resettlement section S2 inner side.Upper lateral process 118a can be formed at by support bar
Around 15 holes passed through.Equally, dividing plate 113c side direction can include the downside prominent to the second resettlement section S2 inner side upwards
Projection 118b.Lower projection 118b can be formed at around the hole passed through by support bar 15.During water jacket 2 vibrates, the
Two friction portions 130 are extruded by upper lateral process 118a carrys out downward side movement, and extrudes next upward side by lower projection 118b and move.
The structure that second resettlement section S2 forms projection 118a, 118b has touching between reduction water jacket supporting part 110 and the second friction portion 130
Area is hit to reduce the effect of strike noise.
On the other hand, the rubbing action between two friction portions 120,130 and support bar 15 is according to the amplitude of water jacket 2
Reveal different shapes.For example, when washing machine is run, according to physical property possessed by whole vibrational system, water jacket is set to resonate, or
In the undue oscillation section that person produces undue oscillation in the inside groove 3 because of the uneven configuration of clothing, the first friction portion 120 and the
Two friction portions 130 are moved with water jacket supporting part 110 in a manner of being formed and being integrated, and thus, kinetic friction force is acted on and supported
Between bar 15.Therefore, in undue oscillation section, actively dissipated because of the rubbing action in the first friction portion 120 and the second friction portion
Vibrational energy.
On the contrary, the amplitude in water jacket 2 is sufficiently smaller than the section (for example, normal vibration section) in undue oscillation section, second
Friction portion 130 constant position kept on support bar 15, and water jacket supporting part are thrown away with the state separated with water jacket supporting part 110
110 are subjected to displacement relative to the second friction portion 130.Therefore, the second friction portion 130 not ride attenuation function, but first rubs
Wiping portion 120 is still moved in a manner of being formed and being integrated with water jacket supporting part 110, so as to the vibrational energy that dissipates.Due to can be only
According to the first friction portion 120 come the vibration based on friction that decays, therefore water jacket can be relatively free to vibrate.
During washing machine is run, suspension 100 is to vibrating relatively stable section (for example, normal vibration
Section) in implement the vibration attenuation based on a friction portion 120, and in undue oscillation section, according to two friction portions
120th, 130 acted on to implement more positive frictional attenuation.That is, the washing machine of the present embodiment consider equipment endurance, can
Vibration displacement of permission etc. come it is default permission amplitude in make water jacket 2 be relatively free to move, and produce regulation level with
On vibration in the case of, actively decay vibration in order to limit amplitude, so as to showing of different shapes shake according to amplitude
Dynamic attenuation characteristic.
On the other hand, although being provided with the two friction portions, however it is different from the present embodiment, the second friction portion 130 is located at
The comparative example of the downside in the first friction portion 120 is observed.Hereinafter, reference picture 6.
Fig. 6 shows that, when being vibrated, water jacket supporting part 110 in downward direction moves successively.In more detail, Fig. 6 (a) portion
It is divided into the situation that the water jacket 2 in vibration processes rises to top side position, the displacement of water jacket 2 is begun to decline.As illustrated, first
Although friction portion 120 start moved with water jacket supporting part 110' with integral manner, but the bottom in the second friction portion 130 with outside
Groove supporting part 110' is separated.When the downward sides of water jacket supporting part 110' are moved to the upper end for starting to promote the second friction portion 130
During state ((b) part of reference picture 6), the position in the second friction portion 130 on support bar 15 is fixed.That is, from Fig. 6's
(a) in a period of the state of part reaches Fig. 6 state of (b) part, water jacket supporting part 110' is relative to the second friction portion 130
Independent displacement occurs.
In the state of Fig. 6 (b) part, water jacket supporting part 110' is in contact with the second friction portion 130, the first friction portion
120 start together to move with the second friction portion 130.Afterwards, Fig. 6 (c) is partly located at the situation of minimum point for water jacket 2, and second
Friction portion 130 maintains the contact with water jacket supporting part 110'.Although it is not shown, but after the state of Fig. 6 (c) part, borrow
Help the restoring force of elastomeric element 150, the upward side movement, and turn into the shape of Fig. 6 (a) part again again of water jacket supporting part 110
State.
In the accompanying drawings, during water jacket 2 declines, the region that the frictional force in the second friction portion 130 acts is shown
Mf' is shown as, the region that the frictional force in the first friction portion 120 acts is shown as ff'.As illustrated, region mf' and ff'
Produce overlapping region cf'.Especially, region cf' is after applying frictional force in the second friction portion 130, by the first frictional force immediately
The section for applying frictional force, is region caused by frictional heat is concentrated.Therefore, the first friction portion 120 is in contact with support bar 15
Part can be deformed by heat, and according to the difference of material, the phenomenon for being bonded at support bar can be produced.Especially, when examining
When considering gravity, if the downward side direction movement in vibration processes of water jacket 2, when upward side direction direction is moved compared with, acceleration
Degree it is bigger, therefore, with the relation of support bar 15, it is big come the frictional force acted by friction portion 120,130, and generate heat
Phenomenon is serious.Also, in the cf' of region, water jacket 2 restarts upward side movement from minimum point (Fig. 6 (c) part), with this
The frictional force based on the first friction portion 120 is produced at the appointed time, so as to which the heating problem based on rubbing action becomes more
Seriously.
In order to solve this problem, the present invention configures the second friction portion 130, and reference in the downside in the first friction portion 120
Fig. 5 observes this structure compared with comparative example, how effectively to solve the problems of excessive heat as caused by frictional force.First, shown in Fig. 5
Reference it is as follows.
(a)：In vibration processes, water jacket 2 is located at the situation of top side；
(b)：Water jacket supporting part 110 moves along downside direction, so as to start the upper end in the second friction portion 130 of promotion
State；
(c)：Water jacket 2 is located at the situation of minimum point；
ΔH1：During water jacket 2 declines, water jacket supporting part 110 is independently subjected to displacement relative to the second friction portion
Region；
ΔH2：The moving displacement in the second friction portion 130；
mf：Apply the region of frictional force by the second friction portion 130；
ff：Apply the region of frictional force by the first friction portion 120；
cf：Region mf and ff overlapping region.
It is different from the above, in the cf of overlapping region, after the frictional force based on the first friction portion 120 is applied, and
It is indirect to apply frictional force by the second friction portion 130, but at least water jacket supporting part 110 in Δ H1 regions to second
After friction portion 130 independently moves, apply frictional force by the second friction portion 130.Therefore, water jacket supporting part 110 at least with
In a period of Δ H1 is accordingly subjected to displacement, cf does not increase frictional heat in region.
According to embodiment, if so that the section that water jacket supporting part 110 can independently move relative to the second friction portion 130
Become longer mode, such as increase the second resettlement section S2 above-below direction length, then the first friction portion 120 can be through overweight
After folded region cf, extend the time that the second friction portion 130 enters overlapping region cf.In this viewpoint, appropriately designed water jacket
The maximum length that supporting part 110 can be subjected to displacement relative to the second friction portion 130, thus, even if with identical with comparative example
Amplitude, prevented also from generation overlapping region cf.
On the other hand, reached again in the first friction portion 120 overlapping from the case that minimum point rises again in water jacket 2
In stipulated time before the cf of region, the friction effect based on the second friction portion 130 can not be produced, and hence it is also possible to suppress
Temperature rises in the cf of overlapping region.
On the other hand, it is preferable that the first friction portion 120 can be moved in a manner of being formed and being integrated with water jacket supporting part 110
It is dynamic, or some displacements and movement can be had relative to the first friction portion 120 according to embodiment, water jacket supporting part 110.So
And in this case, the maximum displacement that water jacket supporting part 110 can independently move relative to the first friction portion 120 is less than phase
The maximum displacement allowed for the second friction portion 130.
First friction portion 120 and the second friction portion 130 may include at least one contacted respectively with the outer peripheral face of support bar 15
Individual friction means, below, it is referred to as the first friction means 121 and the second friction means 131.The material of this friction means can
By felt (felt) etc. there is the elastic materials such as porous fiber or rubber to be formed, morphologically, support bar can be inserted in addition
15 mode in a tubular form, or in having flexible thin slice (sheet) in a manner of the outer peripheral face winding along support bar 15
Or band (band) form.Especially, there is outstanding absorbability to lubricant by fibroplastic friction means.
Elastomeric element 150 is supported by support end 140, and external groove supporting part 110 is flexibly supported.In the present embodiment,
Elastomeric element 150 is stage clip, and placement section 112 is flexibly supported, and is pressed when 2 downward side direction of water jacket is subjected to displacement
Contracting, and launched after compressing more than regulation level, so as to which upward side direction promotes water jacket supporting part 110.
Fig. 7 is shown at the vertical section in the first friction portion 120 and the second friction portion 130 in water jacket supporting part 110.Reference
