The specific embodiment
For further understanding content of the present invention, characteristics, reaching effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
The operation principle of the damping type washing machine among the present invention at first, is described with reference to Fig. 4 and Fig. 5.
The present invention finds out the method that the most effectively reduces vibration in the several different methods that vibration is reduced to propose.In material, thickness and the shape of shock absorber, casing, in the multiple factors such as material of post leg joint portion material, draw optimization post leg joint portion material and be effective method the most in the vibration reduction method.As pointing out out suitable design post leg joint portion material can effectively reduce the experimental result of vibration among Fig. 4 and Fig. 5.
Fig. 4 and Fig. 5 point out out the damping type washing machine principle among the present invention and the chart of effect.That is, for having changed the vibration of it is generally acknowledged in multiple washing machine (to call " test portion " in the following text) the detection dehydration of the resultful all factors of vibration reduction.During the vibration detection test, give the eccentric of 400g and on facial top edge portion (A) in the right side of casing and central portion (B), utilize vibratory output tester (EQP/2) to detect vibratory output.Fig. 4 is the experimental result on the face of casing right side, and Fig. 5 then is the facial experimental result in casing left side.In Fig. 4 and Fig. 5, the maximum vibration that detects in A (maximum) the expression top edge portion, the vibration of the normal condition that detects in A (normally) the expression top edge portion.Identical therewith, as to detect in B (maximum) expression central portion maximum vibration, the vibration of the normal condition that detects in B (normal expression) central portion.
Detailed description is with as follows.Test portion 1 be weld seam that side surface part is formed than general length lengthening 0.15mm, and the material of post leg joint portion material is used the tumbling-box washing machine of butyl rubber.Though test portion 1a is identical tumbling-box washing machine with test portion 1, changed the tumbling-box washing machine of post leg joint portion material material.Test portion 2 is the length that does not change weld seam, and post leg joint portion material also uses the tumbling-box washing machine of the butyl rubber in the prior art.Though test portion 2a is identical tumbling-box washing machines with test portion 2, changed the material of post leg joint portion material.
Here, the post leg joint portion material that uses among test portion 1a and the test portion 2a is that the present inventor is by studying and test the optimal material of result in the various material that draws.(detailed description of coupled columns leg joint portion material is with aftermentioned.)
Fig. 4 and Fig. 5 are analyzed as follows.
Observation is identical for post leg joint portion material, and the test portion 1 that fusion length is different and the experimental result of test portion 2 reduce the effect that has to a certain degree to vibration as can be known when fusion length extends, and the dependency relation between just fusion length and vibration reduce is also not too clear and definite.
But, observe identical for fusion length, the experimental result of test portion 1 that post leg joint portion material is different and test portion 1a or test portion 2 and test portion 2a as can be known, suitable post leg joint portion material to the vibration the reduction effect obvious.
And, observe as can be known, compared with the adjusting of fusion length and optimization post leg joint portion material can effectively reduce vibration for the experimental result of test portion 1a and test portion 2a.
Therefore, need design only post leg joint portion material for effectively vibrating to reduce.
Needs to design the most suitable post leg joint portion material for effective vibration is reduced, therefore, the present inventor studied emphatically post leg joint portion material particularly post leg joint portion material material and draw following result.
Post leg joint portion material at first requires outstanding vibration to reduce characteristic, but for actual application, also need satisfy multiple condition except vibration reduces characteristic.For example, satisfy mechanical characteristic such as hardness simultaneously, washing machine is difficult for from washing machine the slip resistance of sliding the place, the conditions of being convenient to make such as mouldability being set.This be because, reduce characteristic even if for example satisfy vibration, if during no suitable hardness, will resonate in certain field of the use rotation number (RPM) of washing machine, thereby cause washing machine to move.Moreover, and if the frictional force between the floor hour, washing machine then can slide from the floor.
As a result, post leg joint portion material also need satisfy multiple condition except vibration reduces characteristic, in prior art, and the selected comparatively difficulty of the suitableeest post leg joint portion material that all satisfies condition substantially.Therefore, use metal, plastics, butyl rubber etc. as post leg joint portion material so far on the experience, and material all have its length part separately.The hardness of metal or plastics is higher, beyond use rotation number (rpm) section that its resonance field is a washing machine, but irrelevant and with the rotation number section in the mobile phenomenon that washing machine almost all can take place in the fields.Moreover, and if washing machine be provided with between the floor in place frictional force hour, washing machine can produce slip.Under the situation of butyl rubber, slow speed (rpm) section that its resonance field is a washing machine, thus to control it rapidly by the resonance field, though mobile less when high revolution section, the mobile phenomenon of washing machine then can take place when the slow speed section.
The present inventor deals with problems and result that coupled columns leg joint portion material is studied, draws as being used for post leg joint portion material, and the module copolymer of hard module and soft module is the most effective.That is, as shown in Figure 6, utilize the webbed copolymer of hard module (HB) and soft module (SB) to make post leg joint portion material.Because when using the module copolymer of hard module and soft module as post leg joint portion material, the hard module selects to satisfy the material of mechanical characteristics such as required hardness, soft module then selects to satisfy the material that vibration reduces characteristic.Thus, can design the post leg joint portion material that satisfies other condition when satisfying vibration reduction characteristic easily.
Consider the effect that vibration reduces, the module copolymer among the present invention, particularly soft module use the material with creep comparatively suitable, and its creep temperature preferably approaches the serviceability temperature of washing machine.Because when temperature is higher than creep temperature, reticulates the high molecular each several part vigorous exercise of chain attitude of structure and show the character of rubbery state; When temperature is lower than creep temperature, then warm-up movement owing to own vol reduce be suppressed, show the character of glassy state and hardening, reduce effect so reduce vibration.
Because amorphism polymer substances such as rubber have creep, use the rubber material as post leg joint portion material, the existing butyl rubber that uses also has creep.But, as previously mentioned, post leg joint portion material also need satisfy other characteristic except vibration reduces characteristic, butyl rubber is to be added with the copolymer that a small amount of isoprene is made in the isobutene, different with the module copolymer of hard module among the present invention and soft module, difficulty satisfies other characteristic except vibration characteristics.Reduce on the characteristic in vibration, the creep temperature of butyl rubber is-40 ℃
--60 ℃ promptly far below the serviceability temperature of washing machine, so can't be vibrated the reduction effect fully.As shown in Figure 7, the damping property of butyl rubber in washing machine serviceability temperature scope is even haply, but compares with the module copolymer among the present invention, and its damping property is lower.
As mentioned above, use the module copolymer of hard module and soft module as the material of center pillar leg of the present invention joint portion material, the hard module is considered mechanical characteristic, and soft module considers that then vibration reduces characteristic.
Therefore, soft module select creep temperature be the washing machine serviceability temperature near, for example select-30 ℃
-30 ℃ material is more suitable.Certainly, to select to satisfy the material of mechanical characteristic such as hardness more suitable for the hard module.For example, be arranged under the situation of the washing machine that is provided with on the more sliding floors such as cement or porcelain watt, require the hardness of post leg joint portion material high slightly.Usually, the 75-85 of Shore A hardness is more suitable; Reverse side, under the situation on timber material floor, requiring the low slightly common Shore A hardness of hardness is that 25-35 is more suitable.
According to the result that different materials is experimentized and draws, the hard module is made of polystyrene, and soft module then particularly is made of vinyl polyisoprene polyisoprene.
When making post leg joint portion material, can use the module copolymer separately, also can mix at least a kind of material using in the high heat-resisting sincere property resin of olefin-based, ethylene-alpha-olefin copolymer, ethylene-vinyl guanidine-acetic acid copolymer, vinyl-vinyl acrylic acid fat copolymer, s-B-S copolymer, the styrene-isoprene-phenylethene copolymer.In addition, the module copolymer can there be additives such as strengthening agent, filler, softening agent as base material and admixture,, will omit this detailed description because this is self-evident in the current techniques scope.
When the module copolymer of closing soft module with aforesaid hard module is made post leg joint portion material, can form and satisfy the post leg joint portion material that vibration reduces characteristic and other necessary characteristic greatly.
Be to confirm the conclusion that draws, select the material that satisfies condition substantially in the material of Xiao Shouing from the market and experimentize.The material that adopts in the experiment is the Hybrar of Kuraray company.Hybrar is the copolymer of polystyrene and polyisoprene, and its creep temperature is roughly-19 ℃
-Near-8 ℃ the normal temperature.Experimental result as shown in Figure 7, adopts near the cushion effect of post leg joint portion material normal temperature of Hybrar very outstanding.In Fig. 4 and Fig. 5, the material that uses in test portion 1a and the test portion 2a post leg joint portion material is also for adopting the post leg joint portion material of Hybrar.Certainly, the material that is suitable for post leg joint portion material is not confined to Hybrar, but any material that can satisfy condition all can.
Simultaneously, as mentioned above, post leg joint portion material is considered the factors such as manufacturing cost of washing machine except vibration reduces characteristic, need have characteristics such as stronger mouldability, workability.And, on the floor, be difficult for sliding needing stronger anti-sliding for making washing machine.Hybrar has the anti-sliding stronger than butyl rubber, particularly has good frictional force than other rubber-like having under the situation of water.In addition, Hybrar can constitute by penetrating and extruding possible heat burning property resin, also can be made of the possible thermosetting resin of punch process, so have very high mouldability.But, if the additional agent that needs reinforcement will use thermosetting resin the time.
In addition, as shown in Figure 8, the post leg is incorporated in the material of post leg joint portion in decided mode, and it is as follows at first to introduce post leg structure.In general, post leg (5) is by the body (52) of circle, and post head (54) composition that is formed at body (52) lower end.In addition, the outer peripheral face of body (52) is formed with the spiral shell tooth that is used for regulating easily height.Post head (54) plays the body (52) that is formed with the spiral shell tooth and rotates the effect that makes its adjustable column leg height easily.
Wherein, the bottom of post leg (5) is combined with post leg joint portion material (17).Post leg joint portion material (17) can directly be incorporated in the post head (54) of post leg (5), but consider and guarantee bonded area and make it in conjunction with easy, the bottom of post head (54) is provided with enlarged portion (56) separately, and post leg joint portion material (17) then is incorporated in the enlarged portion (56).
Post leg (5) and post leg joint portion material (17) are with inserting mold, bonding or other method combination.For example, post leg (5) and the available bonding agent combination of post leg joint portion material (17), perhaps post leg (5) and the combination of the also available insertion mold of post leg joint portion material (17), moreover can break away from combination with Flexible clamp around post leg (5) and post leg joint portion material (17).
The present invention be not confined to instance graph show and illustrate be incorporated into post leg joint portion material material on the post leg that is provided with on the tumbling-box washing machine body casing.That is, principle of the present invention is equally applicable on other product of vibration reduction usefulness in the washing machine.
