The specific embodiment
Referring now to example shown in the drawings to a preferred embodiment of the present invention will be described in detail.
The principle that has the washing machine of vibration damping is described with reference to Fig. 4 and Fig. 5.
In order to seek the most effective a kind of oscillation damping method, the inventor studies numerous oscillation damping methods.As a result, such as shock absorber, the material of casing, thickness, and shape in numerous factors such as the material of foot pad, can find that the optimization of foot pad is the most effective for weakening vibration.The correct design of checking foot pad is that the most effective result of the test is shown among Fig. 4 and Fig. 5 for vibration damping.
Fig. 4 and curve map shown in Figure 5 show the principle and the effect of the washing machine that has vibration damping according to a preferred embodiment of the present invention.That is, the vibration of different washing machines (hereinafter being called " example ") is measured in vibration can cause the dehydration (spinning processes) of serious problems respectively, wherein knownly usually changes for vibrating effective various parameters.When vibration measurement, the eccentricity (eccentricity) of one 400 gram is set, adopt vibration measurement device (EQP/2) at casing right upper portion turning " A " and right side central part " B " measuring vibrations.
Shown in Figure 4 is the result of the test of casing right side, and shown in Figure 5 is the result of the test of casing left side.In Fig. 4 and Fig. 5, A (maximum) is illustrated in the maximum vibration value that upper corners measures, and A (normally) expression is the normal vibration value that measures in upper corners.Similarly, what B (maximum) represented is the maximum vibration value that measures at central part, and B (normally) expression is the normal vibration value that measures at central part.
To elaborate below.Tumbling-box washing machine of example 1 expression wherein, adds the convex tendon degree of depth of 0.15mm to the common convex tendon degree of depth that the casing sidepiece forms, and foot pad is the same with prior art, is made by butyl rubber.Example 1a represents a washing machine identical with example 1, just the material difference of foot pad.Tumbling-box washing machine of example 2 expressions, wherein, the convex tendon degree of depth does not change, and perhaps the material of foot pad still is the butyl rubber that prior art adopted.Example 2a represents a washing machine identical with example 2, just the material difference of foot pad.
In numerous materials of inventor's research and test,, there is a kind of material to demonstrate best effect (foot pad will be elaborated in the back) as the material of the foot pad that is used for example 1a and example 2a.
Fig. 4 and Fig. 5 are analyzed as follows.
The result of the test of example 1 and example 2, wherein the foot pad of the two is identical, and convex tendon degree of depth difference can be noticed, and to a certain extent, the convex tendon degree of depth is dark more, and vibration damping is effective more.Yet the correlation between the convex tendon degree of depth and the vibration damping is not understood.
Yet, observe example 1 and example 1a, the perhaps result of the test of example 2 and example 2a, wherein the two convex tendon degree of depth is identical, and the foot pad difference can be noticed, appropriate foot pad is vibration damping very effectively.
In addition, observe the result of the test of example 1a and example 2a, as can be seen, for vibration damping, the optimization of foot pad material is more effective than the convex tendon degree of depth.
Therefore, for vibration damping effectively, preferably, foot pad is designed to optimized.
As mentioned above, for damped vibration effectively, preferred foot pad is designed to optimization.Therefore, preferably, at first, the only material of selecting optimal foot pad, particularly foot pad to be carrying out vibration damping, and considers other damping parameter.In view of the above, the inventor has further studied the foot pad of suitable vibration damping, and the results are as follows.
At first, require foot pad to have the favorable damping characteristic.Yet as the actual use of foot pad, foot pad not only needs to satisfy damping behavior, also needs to satisfy other various conditions.For example, such as mechanical performance, hardness, prevent that washing machine from all needing to satisfy from the condition of ground the is installed non-skid property of sliding, the formability of representing ease of manufacture etc.Because, even satisfied damping behavior, if but material does not have enough hardness, in the certain limit of washing machine rotating speed, will produce resonance, cause moving of washing machine.If do not have enough frictional force with the floor, slippage will very may take place in washing machine on the floor.
At last,, also satisfy above-mentioned different condition, in the prior art, still be difficult to select fully to satisfy the best foot pad of above condition even require foot pad except damping behavior.Therefore, up to the present, all can be used as foot pad such as metal, plastic cement, buttress rubber (isobutylene-isoprenerubber) or other, various materials all have its merits and demerits.Even have the metal or the plastics of relative higher hardness, outside the range of speeds of washing machine, also have resonance range, the foot pad of metal or plastics still may move washing machine in nearly all scope of rotating speed, and not will consider the range of speeds.In addition, because the frictional force between the ground of metal or plastics and installation washing machine is less, so the foot pad of metal or plastics also causes the slippage of washing machine easily.Under the situation of using butyl rubber, because butyl rubber has resonance range in the slow-speed of revolution district of washing machine, thereby need the control washing machine so that cross resonance range fast, the foot pad of butyl rubber still might cause moving of washing machine at low engine speed range, although move less at high engine speed range.
For overcoming the above problems, as the result of research foot pad material, it is very effective as the material of foot pad that the inventor finds to adopt block copolymer that hard block and flexible blocks constitute.That is, as shown in Figure 6, the inventor finds that foot pad is preferably formed by copolymer, and wherein hard block HB and flexible blocks SB are netted.Because adopt copolymer by hard block HB and flexible blocks SB, make that can select to satisfy mechanical performance requires material as hardness as hard block, and the material that satisfies damping behavior is as flexible blocks as foot pad.Therefore, foot pad can relatively easily design to satisfy damping behavior, satisfies other condition simultaneously.
Consider the vibration damping requirement, preferably, the material with glass transition is as block copolymer, particularly flexible blocks, and better is that the glass transition temperature of this material is near the temperature of using washing machine.Because though the warm-up movement of the chain copolymer in the net becomes very fierce being higher than under the temperature of glass transition temperature, be rubbery state, but when temperature was lower than glass transition temperature, warm-up movement was suppressed, owing to himself volume reduce to present glassy state, so the effectiveness in vibration suppression variation.
Because amorphous polymer, for example rubber has the glass transition characteristic, thereby preferred rubber is as foot pad.Present employed butyl rubber also has the glass transition characteristic.Yet, as previously mentioned, although foot pad not only needs to satisfy the damping behavior requirement, but also need satisfy other characteristic, different with the block copolymer of hard block of the present invention and flexible blocks, by a spot of isoprene and isobutene polymerisation are formed the copolymer butyl rubber, except damping behavior, can not satisfy other performance.Consider damping behavior, because the glass transition temperature of butyl rubber is-40 ℃～-60 ℃ scope, well below the serviceability temperature of washing machine, so be difficult to obtain required enough effectiveness in vibration suppression.As shown in Figure 7, under the situation of using butyl rubber, although butyl rubber has uniform damping force basically in the temperature range of using washing machine, but in the actual temperature scope of using washing machine, the damping force of the foot pad of butyl rubber will be lower than the damping force of the foot pad of block copolymer of the present invention.
As previously mentioned, foot pad of the present invention is preferably formed by the block copolymer of hard block and flexible blocks, wherein from mechanical angle Selection hard block, from vibration damping angle Selection flexible blocks.
Therefore, preferably, be elected to be the material of flexible blocks, its glass transition temperature is near the serviceability temperature of washing machine.Certainly, preferably, be elected to be the material of hard block, need to consider its mechanical performance such as hardness.For example, when washing machine is installed on the smooth floor of cement or ceramic tile, the foot pad of preferred high rigidity.Usually, preferred Shore hardness is about 80.Relative with it, under the situation of timber floor, preferred soft, its Shore hardness is about 30 usually.
As the result who tests on different materials, the inventor draws hard block and selects polystyrene for use, and flexible blocks is selected polyisoprene for use, especially vinyl polyisoprene.
In the making of foot pad, although can use block copolymer separately, should from alkylene thermoplastic resin, ethene-α base olefin copolymer, vinyl-acetate copolymer, ethene-third ethyl acetate copolymer, s-B-S copolymer and styrene-isoprene-styrene copolymer-, select at least a kind ofly to mix with block copolymer.In addition, also can join in the matrix material of block copolymer such as the additive of crosslinking agent, filler and softening agent (softner), it is known by those of ordinary skill in the art, detailed be described in this and will be omitted.
As described, the foot pad of the block copolymer of hard block and flexible blocks makes the foot pad of making can satisfy damping behavior and other required performance demands fully.
In order to verify, the material that can satisfy above condition in the commercial material is substantially tested.The test selected materials is the Hybrar of Kuraray company.This Hybrar is the block copolymer of a kind of polystyrene and polyisoprene, and its glass transition temperature is near about-19 ℃～-8 ℃ room temperature.As shown in Figure 7, the foot pad that can confirm Hybrar has extraordinary damping force near room temperature.In Fig. 4 and Fig. 5, the foot pad material among example 1a and the example 2a is Hybrar.Certainly, the material that is suitable for foot pad is not limited to Hybrar, and any material that satisfies above condition can use.
Simultaneously as described, preferably, foot pad not only has the favorable damping performance, considers the production cost of washing machine, and foot pad also should have good formability and workability.Hybrar has better nonslip properties than butyl rubber, and particularly, Hybrar is with other rubber phase ratio even still have good frictional force under the environment of humidity.In addition, because Hybrar can be used as the thermoplastic resin of casting or extrusion molding, or as squeezable thermosetting resin, Hybrar also has the good advantage of formability.Yet,, need to add independent crosslinking agent if plan Hybrar is used as thermosetting resin.
Meanwhile, referring to Fig. 8, leg and foot pad link together by a kind of predetermined method.The preferred embodiment of connection of leg and foot pad will be described with reference to figure 8～11.
Leg is at first described.Usually, leg 5 comprises a columniform body 52 and a head 54 that is positioned at body 52 bottoms.Preferably, body 52 is threaded, thereby can regulate height at an easy rate.Head 54 is used for making threaded body 52 to rotate easily, thereby makes the adjusting of height be more prone to.
Simultaneously, foot pad 17 is assemblied in the bottom of leg 5.Though foot pad 17 can directly be assemblied in the head 54 of leg 5, preferably, an expansion section 56 is formed at the bottom of head 54, is convenient to assembling to locate a fitting surface.
Leg 5 and foot pad 17 can be connected by insert molding (insert molding), bonding or other method.For example, as shown in Figure 9, leg 5 can be connected by adhesive with foot pad 17.Perhaps as shown in figure 10, leg 5 and foot pad 17 are connected by insert molding.Or as shown in figure 11, utilize a groove 17a, this groove excises and forms from the part of the bottom of foot pad 17 at circumferencial direction, and leg 5 can be by being connected with elastic hook 19 with foot pad 17, and this elastic hook is coating the expansion section 56 of leg and the groove 17a of foot pad 17.
Simultaneously, although foot pad is formed by a kind of material, that is, described in the above-described embodiments block copolymer forms, and according to the inventor's result of study, finds also can adopt two or more materials to form foot pad.That is to say, preferably, foot pad comprise with contacted first parts in floor that washing machine is installed and with contacted second parts of first parts, and in first, second parts at least one form by block copolymer, another is then formed by other material such as butyl rubber.Because above-mentioned foot pad material, promptly the block copolymer of hard block and flexible blocks may cause plastic deformation after the certain hour section, so effectiveness in vibration suppression is relatively poor.Particularly, will become poorer in the low temperature range effectiveness in vibration suppression.
Other embodiment of foot pad of the present invention is described with reference to Figure 12～17.
Referring to Figure 12, foot pad 17 comprise one with the contacted first parts 17a in floor and second a parts 17b who is connected with the first parts 17a that washing machine is installed, wherein preferably, one among the first parts 17a and the second parts 17b is formed by butyl rubber, and another is then formed by block copolymer.For convenience, represent that with the hatching (for example, the label 17b among Figure 12) that the right side makes progress this material is a block copolymer, and other mark on the section (for example, the label 17a among Figure 12) represents that this material is a butyl rubber.
Referring to Figure 12, although the first parts 17a is formed by butyl rubber, the second parts 17b is formed by block copolymer, as shown in figure 13, is more preferably, and the first parts 17a is formed by block copolymer, and the second parts 17b is formed by butyl rubber.Because block copolymer can contact better with the floor, thereby the preferred first parts 17a is formed by block copolymer.
Simultaneously, referring to Figure 14 a and 14b, the first parts 17a can have a ledge 170 that passes the second parts 17b.Perhaps shown in Figure 15 a and Figure 15 b, the first parts 17a can have a plurality of ledges 170 that pass the second parts 17b.
Perhaps referring to Figure 16 and Figure 17, the 3rd parts 17c that material is identical with the first parts 17a is connected to the top of the second parts 17b.

Simultaneously, the inventor finds that under study for action principle of the present invention is not only applicable to vibration damping on the leg of washing machine and similar device thereof, but also applicable to other assembly.Especially, principle of the present invention is preferably applied to be installed on the shock absorber between casing and the bucket, with the vibration transfer that prevents washing machine etc. to casing.
Below with reference to Figure 18 the application of principle of the present invention on the roller washing machine shock absorber described.
One end of shock absorber 15 is fixed on the bottom 36, is a damping means 100 between the two.In this example, though damping means 100 can be that block copolymer forms separately by a kind of material, yet result of study according to the inventor, find that it also is possible that damping means 100 of the present invention is formed by two or more materials, for example, a part is formed by block copolymer, and another part is then formed by other material such as butyl rubber.Because after through the certain hour section, the block copolymer of hard block and flexible blocks can produce plastic deformation, thereby effectiveness in vibration suppression is relatively poor.Especially effectiveness in vibration suppression becomes poorer when low temperature.
To carry out more detailed description below.For convenience of description, right side hatching (as the label in Figure 18～21 120) up represents that this kind material is a block copolymer, and other mark (as the label in Figure 18～21 110) represents that this material is a butyl rubber.
Referring to Figure 18, shock absorber 15 is fixed on the bottom 36, between the two, first damping means 110 contacts with shock absorber 15, and second damping means 120 contacts with first damping means 110, and wherein in first damping means 110 and second damping means 120 is the block copolymer of hard block and flexible blocks.
In more detail, shock absorber 15 is having a hollow connecting portion 15a near bottom half one end.In connecting portion 15a, be equipped with columniform first damping means 110, and columniform second damping means 120 is assemblied in the hollow bulb of first damping means 110.A support 16 that has to a side of shock absorber direction opening is fixed on the bottom 36.
In other words, the connecting portion 15a of shock absorber 15, first damping means 110 and second damping means 120 are arranged in the opening of support 16, and in this state, a bolt 16a passes the support 16 and second damping means 120, and shock absorber 15 is assemblied between bucket and the casing.
Meanwhile, referring to Figure 18, first damping means 110 is formed by butyl rubber, and second damping means 120 to be formed by block copolymer also be possible.Yet, as shown in figure 19, preferably, first damping means 110 is formed by block copolymer, and second damping means 120 is formed by butyl rubber, because from the vibration damping angle, preferably, form by block copolymer with shock absorber 15 contacted first damping means, 110 first-selections.
In addition, referring to Figure 20 and 21, can also in second damping means 120, assemble a material three damping means 130 identical with first damping means 110.Certainly, also can be at material of first damping means, 110 outsides assemblings the 3rd damping means 130 identical with second damping means 120.
Meanwhile, first damping means 110, second damping means 120 and the 3rd damping means 130 are except can linking together by bonding or double injection method of molding, and parts can also connect by other method, and detail is omitted at this.
Though only tumbling-box washing machine has been carried out diagram and description in above embodiment, the present invention is not limited thereto.That is to say that the present invention also is applicable to pulsator washing machine and agitator type washing machine.In addition, the present invention is not only applicable to be connected to the leg on casing, the body, is applicable to other the parts that are used for the washing machine vibration damping yet.
Obviously, for a person skilled in the art, under the prerequisite that does not deviate from the spirit and scope of the present invention, can make various changes and variation to the present invention.Therefore, various change of the present invention, the content that changes by appending claims and equivalent thereof contain.
As previously mentioned, be used to cut down the method for vibration of washing machine and use the washing machine of this method to have the following advantages.
At first, can effectively weaken vibration by selecting foot pad rightly, in other words, the vibration of washing machine can be reduced effectively, and those increase the design of product cost, tank material, thickness, and the change of the convex tendon degree of depth is then very little.That is to say, by the damping means of suitable selection shock absorber, and leg, its design is confirmed relative being easier to effect, and vibration can effectively be weakened.
Secondly, the present invention allows to select a kind of foot pad, and it can not only satisfy the requirement of damping behavior, and can satisfy such as other necessary characteristic such as hardness and nonslip properties, thereby also allow a kind of washing machine of design simultaneously, at the equal vibration damping effectively of all ranges of speeds of washing machine.
