Description
The present invention relates to the washing machine field.
In the prior art, China's utility model (CN2159403Y) discloses a kind of ball rubbing type washing machine, evenly inlay a lot of protruding plastic strips parallel or wooden on this inner tank of washing machine sidewall with axis, (size is certain) of throwing in a kind of some during washing again in inner core helps the ball syringe of rubbing effect, when rotating for weakening inner core, the strike note that sends between ball syringe and inner core inwall, the ball syringe appearance is coating the garment bag that has the effect of waterproof corrosion resistant concurrently.In inner core when rotation, drive the clothing lift-over by the plastic strip of projection and beat, and ball syringe and clothing friction constantly takes place are able to clothing washed and float totally simultaneously.Here we are not difficult to find out, this technology, certainly will will be selected out these little ball syringes after promptly laundry finishes one by one for user's not convenient property among the parcel of clothing.China's utility model also disclose apply for artificial same people by name " Water Extraction Machinery automatic equalization part " (CN2076568U) and " the automatic compensating part of centrifuge dewatering " two technology (CN2084942U) by name, because of the operation principle basically identical of these two technology, be example with " Water Extraction Machinery automatic equalization part " at this.The core of this technology be with one or more inner sealings some water soft (as rubber) the ring pipe suit or be fixed on the inner core madial wall, this ring pipe can have many groups.Its operation principle is: many its centrifugal force of zone of clothing accumulation is greater than and piles up few zone during dehydration, thereby clothing formed the pressure that varies in size to being trapped among the flexible pipe of inner core madial wall on circle, and the water in the pipe of the big zone of pressure is with regard to the oppressed little zone of pressure that flows to.Play the effect of balanced inner core spin stabilization thus.Its principle is feasible, but for the very uneven situation of putting on the inner core sidewall, its effect probably is limited, moreover its starting point and do not lie in and clothing will be put evenly, but will adapt to this inhomogeneous.
The present invention is not careful and not comprehensive for addressing the above problem with the ubiquitous rubbing of all models class automatic washing machine at present exactly, and all being difficult for stably during dehydration, problem designs.

Figure 12 and Figure 13 represent other two kinds of shapes of roller (2), respectively have crown of roll (6) and (6 ') and their surface that the rib and the equally distributed small embossment point of projection are also all arranged thereon, for illustrating conveniently, do not draw at this.
Figure 14 represents the roller (2) and the assembling schematic diagram of axle sleeve (3) with (3 ') of another form, and after slender axles (8) penetrated roller (2), the extending part, two ends embedded in axle sleeve (3) and (3 ').For illustrating conveniently, roller (2) body surface epirelief barring and spherical small embossment point all do not draw.
The present invention compares with prior art, has lot of advantages, referring now to each accompanying drawing comparison be described as follows: common When the rotary drum washing machine of bucket was done washing in the type, the clothing group that is immersed in the water did respectively intermittent clockwise or contrary with current Conterclockwise rotation, because of general smoother all on the inner core madial wall, thereby the clothing base to passing each other by a shave with it Do not produce the rubbing effect on the basis. But the inner core after employing the technology of the present invention is because having installed by a set pattern on its madial wall Then the roller free to rotate (2) of equally distributed some is done intermittence with current equally in clothing group like this When both forward and reverse directions rotates, clothing group will produce the frictional force with certain normal pressure, frictional force to all rollers (2) (20 rotation takes place, and the result of rotation is that the distinctive protruding rib of roller (2) and spherical small embossment point are right to cause all rollers Clothing produces even, careful and comprehensive rubbing, situation as schematically shown in Figure 5. We can find out this thus Brightly wash when floating being used for vertical shaft impeller-type or stirring type fully-automatic washing machine, help the principle of rubbing effect and it excellent Characteristic in essence in general other various forms inner core. For the vertical shaft impeller-type that adopts common inner core technology or Stirring type fully-automatic washing machine, the operation principle during its dehydration is such, that is: because each clothing group and clothing Each position of thing group is different from the contact area of inner core madial wall, different and each contact-making surface of the normal pressure between contact-making surface On the difference (that is coefficient of friction difference) of clothing quality, therefore when the unexpected High Rotation Speed of inner core, each clothing is rolled into a ball and is existed The frictional force that produces between inner core madial wall contact-making surface is just very not identical, but also because entwining between each clothing group, Assorted wrong complexity with involving, they just can obtain different acceleration and speed, rotate with the inner core madial wall Acceleration (angular acceleration) identical, can paste immediately with madial wall synchronous high-speed running, with madial wall acceleration phase Than each little clothing group, must after after a while, just can reach the running speed synchronous with madial wall, and And the in other words displacement of relative sliding with respect to madial wall must take place at this moment these clothing groups obviously, according to Each clothing group distance that take place or that do not slide or slide but slide is again different, each the clothing group in the inner core Be able to come in the madial wall evacuation. But it often is not good that this sliding is evacuated effect. This be because Suddenly each clothing group that takes place is with inner core madial wall or constant speed, or low speed or more in the rapid rotation of low speed slightly, each clothing Thing group can obtain never to arrive great centrifugal force in short moment, and centrifugal force makes each clothing group form synchronously madial wall The normal pressure that direct ratio increases rapidly. As everybody knows on physical mechanics, two objects that are in contact with one another, its contact-making surface Between the relative motion that produces frictional force at coefficient of friction one regularly, frictional force is proportional to normal pressure. Just this Main cause is so the displacement that each clothing group slides at the inner core madial wall is extremely limited and is to lack moment namely End, thus each clothing group often the uniformly evacuation of order come. That therefore sells in the market is a lot The vertical shaft full-automatic pulsator washing machine of brand posts a label mostly, above with roughly content: ' machine sometimes Can cut dehydration, and again water filling in the bucket, this is for making clothing put the normal procedure of evenly establishing, and Non-fault, still uneven behind above-mentioned action triplicate, the machine caution that will pipe woulds you please in person clothing be put Flat ' ... ... The technology of the present invention can overcome the not enough and cited " dehydration of the above plain edition inner core just The machine automatic equalizing part " weak point. The principle of the technology of the present invention is: utilize roller free to rotate (2) passable Help each clothing group that the displacement of big distance sequentially takes place successively, well-known force of rolling friction will be far smaller than cunning Kinetic force of friction is so although the normal pressure that each clothing is rolled into a ball the inner core madial wall increases rapidly (that is contact-making surface in short moment Between frictional force increase rapidly), but roller (2) still can help the displacement of clothing group mobile one big distance, until contact-making surface Between the frictional force movement that greatly each clothing is rolled into a ball to a certain degree the time just can stop; Roller (2) just also has an effect in addition Be that abrasive tumbling is and out-of-date on it when the clothing group that contacts with it, quick rotation can take place in roller (2), and this rotation has Help this clothing be broken up or the mobile clothing of coming of next group is broken up, it also helps to squeeze clothing simultaneously The excessive moisture of group. The schematic diagram that Fig. 6 is drawn and the schematic diagram of Fig. 7 just are the bodies to the visualization of above-mentioned analysis Existing. We have drawn and have helped dewatering stability when the present invention is used for impeller-type or stirring type fully-automatic washing machine thus Advantage and be different from the advantage in essence of other common inner core. Horizontal axis rotary drum washing machine for common inner core , washing of it floated principle and is: when the intermittent both forward and reverse directions rotation of inner core low speed, because in clothing group and the inner core The effect of frictional force between sidewall (the comprising convex tendon) contact-making surface, the clothing at each position of contact-making surface will be with the inner core madial wall Do constant speed or slightly low speed or more low speed ... the motion that accompanies, clothing is rolled into a ball in the inner core madial wall during constant speed does not have between contact-making surface Relative motion takes place, clothing group slightly low speed or more low speed or ... the time then produced relative motion, i.e. clothing between contact-making surface The phenomenon of skidding has taken place in the inner core interior side-wall surface in group. Each position of rolling into a ball away from the clothing of contact-making surface in addition, because of Be not subjected to or directly be subjected to the effect of frictional force between contact-making surface, its original effect of inertia will make these positions protect as far as possible Hold static, so whole group's clothing (namely two kinds of power is not in opposite directions passed this clothing group not on same straight line at these two kinds Actual effect center of gravity place) under the effect of power, lift-over will take place. But also owing to clothing group is raising with the lift-over of inner core madial wall During to certain altitude, with the gradually increasing of gravity effect, this clothing group also can drop and descend. Clothing group continuously not Disconnected lift-over and beating, exactly common interior cartridge type tumbling-box washing machine is washed the operation principle of floating clothing. Adopt the present invention The horizontal axis rotary drum formula washing machine of technology, the maximum characteristics of its inner core are exactly respectively by one on three curved surface convex tendons (5) Set pattern has then been installed the roller free to rotate (2) of some, at the every equidistant inner core of adjacent two convex tendons (5) of distance Some rollers (2) free to rotate have also been filled respectively on three lines of sidewall. During laundry, when clothing group with in Frictional force between tube madial wall contact-making surface makes this clothing group each position of contact-making surface accompany with the speed with the sidewall constant speed and transports When moving, be embedded in following all rollers (2) by clothing group pressure obviously and rotation can not take place. This moment convex tendon (5) Effect be tantamount to convex tendon on the plain edition inner core, and another string is pressed the roller (2) that buries also can temporarily regard as by clothing group Be a special convex tendon, anticipate as shown in Figure 8 V among Fig. 81Represent direction of rotation and the speed of inner core, V2Represent that clothing group accompanies the inner core madial wall and the direction of motion and the speed of moving. This moment V1＝V
2, relevant all are rolled Rotation does not all take place in wheel (2). But when a clothing is rolled into a ball to accompany than the lower slightly or lower speed of inner core madial wall movement velocity And when motion, the slip with respect to madial wall has taken place in this clothing group obviously, and the result of slip makes by pressure and buries Roller (2) rotation has taken place, and the result of rotation that to be the region of interest of clothing group that contact is crossed produced is careful With comprehensive rubbing effect, meaning is such as shown in Figure 9, V among Fig. 91Represent direction of rotation and the speed of inner core, V2Be direction and the speed that clothing group moves with madial wall, V2＜V
1, so skidding has taken place at madial wall, V in this clothing3And V4The direction and the speed that cause the rotation that two groups of rollers (2) take place respectively for clothing group after skidding Degree. Because clothing is rolled into a ball ever-changing that shape takes place at any time, the actual conditions of contact-making surface are (such as normal pressure, friction in a word The parameters such as coefficient) also be fast changing, so the roller (2) of the upper tandem of curved surface convex tendon (5) and not on convex tendon (5) The roller of tandem (2) when clothing group contact with regard to turning to of being in all with quarter at any time that the instant becomes with do not turn among. Do not turn to The time, the tandem of all rollers (2) can be seen as the effect of common convex tendon, because of this special " convex tendon " Have six at this inner core madial wall, so obviously they have increased the rubbing dynamics that clothing is rolled into a ball greatly; And When roller (2) tandem was rotated (rotation), the rib of roller (2) side projection and uniform spherical small embossment point were equally to clothing Thing group has produced comprehensively and careful rubbing, from we are not difficult to find out that also working as the technology of the present invention is used to trunnion axis here During tumbling-box washing machine, it help the unusual property of crumpling. When being used for the horizontal axis rotary drum formula, the technology of the present invention washes In clothing machine when dehydration,, it helps the principle basic phase of the principle of inner cylinder rotating stability with for the vertical shaft impeller-type time With, also be to utilize roller (2) to the rolling action of clothing, clothing group is sequentially produced and inner core madial wall rotation side To opposite relative sliding, prolonged as far as possible times that all clothings are rolled into a ball acquisition finally and inner cylinder rotating speed is synchronous in the tube Long, increase rapidly to eliminate clothing group centrifugal force moment whereby, cause the moment of inner core madial wall normal pressure synchronous Direct ratio increases rapidly, thereby makes clothing group along the inner core madial wall too short drawback of sliding distance in turn, and it passes through help Clothing group prolongs in proper order sliding distance and reaches clothing group is evacuated the order of evenly realizing helping dewatering stability as far as possible . Content shown in Figure 10 is: arrow V1Be inner core (1) dehydration direction of rotation and the speed in a certain moment when initial, V2And V3Direction and the speed with respect to inner core madial wall and the slip opposite with the madial wall direction of motion that represent respectively that two different parts of clothing group take place, V4，V

7Represent that respectively the roller (2) of different parts is in clothing group Direction and the speed of the moving lower rotation that takes place of wiping, Figure 11 represents after after a while, all clothings in the inner core Group is at the state of being evacuated under the help of all rollers (2) after putting evenly, and because of clothing group any phase no longer takes place this moment To sliding phenomenon, so all rollers (2) all are in the state of no longer rotation.
The present invention compare with prior art have compact conformation, the wash degree height, do not hinder clothing, water-saving, save time power saving and when dehydration more stable advantage, particularly concerning horizontal axis rotary drum formula washing machine, can greatly shorten the stationarity of washing time of floating and greatly improving dehydration, because of the very big raising of dehydration stationarity thereby can improve the rotating speed of dehydration electric motor greatly.The weight of heavy cement counterweight (or other counterweight) can be considered to cut down significantly in the horizontal axis rotary drum type washing machine in addition, thereby make no matter the washing machine of this kind type is to use in household, still when industry manufacturing and transportation, all reach a brand-new spry and light and leap newly easily.The very big raising of stationarity during in addition also owing to dehydration, therefore no matter the technology of the present invention (referring to drum-type, impeller-type and stirring-type) when being applied to pandemic three kinds of washing machines is to be used for that a kind of damping part, motor, transmission mechanism, auxiliary circuit, computer program central layer and machinery that can make washing machine and electronic programmer and whole supporting frame to reach the effect that greatly increases the service life simultaneously, and all these are the place of the final purpose of advantage of the present invention place and the technology of the present invention just in a word.
