Below, the moving of cloth of the shape of agitator and washing and the washings when dry is described.
Fig. 2 is the stereogram of the agitator of an embodiment of the invention.The surface of agitator 4 is about perpendicular to the symmetrical V-shape of the axle (representing with double dot dash line B-B among the figure) of the rotating shaft of agitator 4, is made of the valley portions 4c between clinoplain 4b that uprises from the center towards peripheral part and clinoplain 4b.A plurality of aperture 4a of the warm braw when water when mobile the washing being arranged and drying on the surface.From washing and dewatering bucket 2 (fixing a side), when agitator 4 rotations, the surface of agitator 4 increases height from valley portions 4c gradually to the top of clinoplain 4b, and behind the arrival topmost, 4c highly reduces towards valley portions.The point that the height on the surface of agitator 4 gradually changes is very different with the agitator that Figure 12 and Figure 13 represent, this is preventing to have brought into play very big effect in the cloth winding.In the present embodiment, when agitator 4 rotated for 1 week, the surface of agitator 4 took place 2 times and moves up and down.This moving up and down amplitude is near peripheral part is big more more.
The agitator of Figure 12 and Figure 13 here is described.
In possessing the scrubbing-and-drying unit of agitator,, in washing procedure and dry operating, need to reduce cloth and twine in order to realize producing the few dry finishing of fold.Twine if cloth takes place, the shape of the part of winding will fixedly cause fold to produce.The agitator 52 that Figure 12 represents is bent upwards peripheral edge portion with bit by bit pushing to and forms the plate-like form, is provided with the many radial blade 52b that protrude upward on its surface.A plurality of apertures of the warm braw when 52c is mobile draining of washing and drying.Radial blade 52b produces cleaning strength by the rubbing action of friction washings 38 and the kneading action that washings 38 is out of shape.
Figure 13 is the cutaway view that has dissectd agitator 52 along the A-A line of Figure 12.Because blade 52b is outstanding with anxious angle with respect to the seating plane of agitator 52, so when agitator 52 rotations, effect has the revolving force bigger than centrifugal force on washings 38.That is: on the part of the protuberance b outstanding with anxious angle, to compare with the two side portions of the direction of rotation of this protuberance, the power that washings 38 is accepted from this protuberance is that face is pressed and sharply become big.Thus, this protuberance becomes the power that washings 38 transports to direction of rotation greatly.Washings 38 as shown in figure 13, one side is slided on agitator 52 and is rolled, one side is pushed by blade 52b or is tangled by blade 52b, rotates with the direction of rotation of agitator 52 equidirectionally.In addition, though blade 52b also produces the power that will lift washings 38, because blade 52b is outstanding with anxious angle, b is also little for its width, so this power is very small, produces the moving of above-below direction of washings 38 hardly.In addition and since power small and that produce only be added in the overlapping washings contact with agitator 52 or very approaching washings on, biography is less than the washings that is positioned at the upper strata.
When washings 38 rolled on agitator 52, washings 38 easily became the wad shape, becomes the state that Yi Fashengbu twines.And, as shown in figure 12, if dispose washings 38 to periphery, because the central part of agitator 52 and the speed difference of peripheral part from the center of agitator 52, the part that is positioned at peripheral part is rolled more, takes place to twist around (obviously taking place on the long sleeves of shirt and the isometric clothing of trousers).Because agitator 52 rotating repeatedly, thus should twist around eliminating by rotating round about, but in fact washings is not positive and negative rotation symmetrically, twists around meeting gradually more very.Owing to should twist, further easily become the state that cloth twines thus around making washings 38 become the faciola shape.Thus, the fold of clothing corrugation takes place on washings 38, dry finishing reduces.
Twine in order to reduce cloth, the anglec of rotation of agitator is diminished (reduce rotation number, shorten rotational time), but be in the suds, the mechanical force that offers washings will diminish, and cleaning strength will reduce.In addition, in drying, elongated problem of uneven drying and drying time can take place in moving of cloth or alternately will diminishing of cloth.
With Fig. 3 to Fig. 5 moving of when washing and the washings when dry is described.Fig. 3 is the figure that about in a circumferential direction half cycle has launched agitator 4, and moving of washings 38 on the agitator 4 has been described.Fig. 4 is the longitudinal section of washing and dewatering bucket 2, and Fig. 5 dissects washing and dewatering bucket 2 along the C-C line among Fig. 4, the vertical view of seeing from the top.
When washings 38 was on the position of the valley portions 4c that (I) by Fig. 3 represents, if agitator 4 rotates in the direction of arrows, then washings 38 one sides were slided on the clinoplain 4b of agitator 4 simultaneously and the equidirectional rotation of the direction of rotation of agitator 4.The surface configuration of agitator 4 be not as shown in figure 13 mixing arm from the surface with the outstanding shape of anxious angle, but the shape of smooth variation, thus washings 38 can not pushed down or tangle by blade, so washings can not become wad shape or winding.Simultaneously, washings moves (upward lift) along clinoplain 4b to the top of clinoplain from valley portions 4c (I) by wedge effect, after arriving topmost (II), because gravity and moving, repeat to return the motion of the above-below direction of valley portions 4c (III) once more downwards.At this moment, by selecting the rotation number of agitator rightly, the intrinsic vibration number of the above-below direction of washings motion is consistent with the moving up and down vibration number of blade surface, can more effectively offer up and down mobile of washings.
In addition, as Fig. 4 and shown in Figure 5, the centrifugal force that the rotation of washings 38 by agitator 4 brings moves to the peripheral part of agitator 4, along the internal face Zhou Fangxiang ground configuration of washing and dewatering bucket 2.This is that the surface configuration of agitator 4 gently changes in direction of rotation, so the power of washings 38 centrifugal force than direction of rotation is acted on more strongly because as previously mentioned.Because the amplitude of the above-below direction of the blade surface of peripheral part is big, so can more effectively very big moving up and down be offered washings 38.And, because the rotation one of agitator stops to add the motion to valley portions 4c whereabouts,, washings 38 replaces, washs inequality or uneven drying so can not taking place.That is: the moving of the above-below direction of washings 38 by washings 38 that focuses on the peripheral part of agitator 4 by centrifugal force disperseed.And then, since not as shown in figure 12 washings distribute from the center of agitator 4 to peripheral part ground, so can be owing to the speed difference of interior week and periphery on clothing generation stubborn around.
So, washings 38 rotates with the direction of rotation of agitator 4 in washing and dewatering bucket 2 when above-below direction moves equidirectionally.Move up and down along clinoplain 4b by washings 38, when washing, washings 38 can be washed and clean by the effect of compressing and washing by beating.In addition, when drying, by the volume that can effectively utilize washing and dewatering bucket 2 that moves up and down of washings 38, washings 38 easily launches in washing and dewatering bucket 2, can realize the drying that fold is few.And, because rotating one side on the direction of rotation of agitator 4, washings 38 one sides move up and down, so between washings, produce the gap, warm braw not only passes to the surface at washings 38, also easily pass to inside, can promote the evaporation of the moisture in the washings 38 thus, can shorten drying time.
And then agitator 4 is compared the advantage that the water yield when reducing washing is significantly arranged with the agitator of Figure 12 and Figure 13.With regard to the agitator of Figure 12 and Figure 13, abundant in washroom dehydration barrel washed water, washings 38 becomes the state that floats (leaving) from the agitator surface a little owing to buoyancy.Under this state, by agitator rotation, the blade 52b washings 38 that rubs obtains cleaning strength.If reduce the amount of washings on the agitator of Figure 12 and Figure 13, then washings 38 places on the agitator 52, and blade 52b falls into in the washings 38, and blade 52b and washings 38 become engagement.Under this state, if agitator 52 rotations, then washings 38 and roughly rotation integratedly of agitator 52 do not produce relative motion, do not produce cleaning strength.
Different therewith, the surface configuration of agitator 4 gently changes.Thus, even if the few washings 38 of the amount of washings places the state on the agitator, if the agitator rotation, then washings 38 one sides are slided on agitator, and one side is moved at above-below direction by the wedge effect of inclined plane 4b, produces cleaning strength.In addition, when reducing the water yield, spread all over washings integral body, the cycling mechanism of washings preferably is set, from the top spray washing water of washings in order to make washings.
The shape on inclined plane as shown in Figure 6, even if chevron also can realize and the moving of above-mentioned roughly the same cloth.The surface of agitator 50 is inclined plane 50b of the roughly chevron that uprises of the therefrom mind-set peripheral part by fan-shaped and the valley portions 50c that couples together between the 50b of inclined plane is constituted.Periphery at agitator 50 has summit (top) 50d that made progress in 2 week, forms valley portions 50c between summit 50d and summit 50d.From pivot apicad 50d form the 50e of ridge portion uprise highly gradually.The direction difference that inclined plane 50b points in the circumferential both sides of the 50e of ridge portion.In addition, inclined plane 50b both can be the plane, also can be curved surface.50a is an aperture, the warm braw when water when flowing washing and drying.Fig. 7 is that expression launches agitator 50 figure of the change of shape of the circumferencial direction of inclined plane 50b at circumferencial direction.The feature of this agitator is to make the chevron shape, and it is big that the angle of inclination of the circumferencial direction of its inclined plane 50b becomes at first gradually towards the summit, diminishes gradually near summit rear-inclined angle.Thus, the foot of a mountain portion of inclined plane 50b is from the smooth and easy connection of valley portions 50c, and the effect on run-up road is played by this foot of a mountain portion.Washings 38 can one side slide in this run-up, and one side is takeoff near the summit of angle of inclination steepening effectively upward.Thus, bigger moving up and down can be offered washings.
In addition, big even if the radial skew angle of inclined plane 50b becomes, make the difference of height on agitator surface become big, because change of shape is mild, clothing also is difficult to roll, and very big moving up and down can be provided with not twining on washings.Therefore, can improve cleaning strength and drying efficiency.Certainly, preferably make the center angle of the fan on chevron inclined plane increase (near 180 °) as far as possible, make inclined plane 50b big, valley portions 50c is little.
Agitator also can be the shape that single inclined plane 51b is arranged as shown in Figure 8.Inclined plane 51b crosses the inclined plane that rotary middle spindle is cross over the other end one side from peripheral part.51c is the bottom surface that is connected the lowest part of inclined plane 51b, a plurality of apertures of the warm braw when water when 51a is mobile washing the and drying.On figure, represent inclined plane 51b, but also can be inclined plane as the chevron of Fig. 6 by the plane.Inclined plane 51b has half or the above size that occupies agitator 51 at least.Agitator 51 integral body can certainly be made inclined plane 51b (at this moment not having bottom surface 51c).But because the effect on bottom surface 51c performance run-up road, so in about 1/4 scope from the outer thoughtful diameter of agitator 51 bottom surface 51c is set, washings is easy to move to the top of inclined plane 51b.Even if the feature of this shape is not make the angle of inclination of inclined plane 51b become big, also can make the difference of height of inclined plane 51b big.Compare with the agitator that possesses the opposing inclined face that Fig. 2 represents, can guarantee the most about 2 times difference of height with identical angle of inclination.Thus, can make moving up and down of washings 38 bigger, more effectively use the volume of washing and dewatering bucket 2, washings 38 easily launches when drying thus, can suppress fold and produce.
The quantity that is present in the summit (top) of the peripheral part of agitator in Fig. 6 and Fig. 7 is 2, but also can consider to make as shown in Figure 93.(a) being the stereogram of agitator, (b) being side view, (c) is to overlook (blade surface) figure.In the agitator 60 of Fig. 9, circumferentially forming 3 valley portions 60b and the peripheral part between valley portions 60b and valley portions 60b formation top 60a.Between valley portions 60b and valley portions 60b, to top 60a, uprise highly gradually from rotating center section.At this moment, form the ridge 60e of portion from rotating center section to top 60a, at different inclined plane 60c, the 60d of each self-forming pointing direction of circumferential both sides of the 60e of this ridge portion.This inclined plane 60c, 60d both can be formed by the plane, also can be formed by curved surface, if remove beyond the quantity of summit 60a and valley portions 60b, then the agitator of shape and Fig. 6 is same.But, the quantity on summit is many more be difficult to make the height on summit to uprise more and the inclination on inclined plane diminish flatten slow.Rated capacity to washing and dehydration is that 6～10kg, drying capacity are washing machine or the scrubbing-and-drying unit about 2～8kg, and the quantity on summit (mountain) is preferably 1～3.In addition, if make the height on summit become higher very big moving up and down offered washings, and make the inclined plane mild for inclination is diminished, then the quantity on summit is for few more good more.If the balance when considering the agitator rotation is then preferably made the summit 2.
As mentioned above, the agitator of the respective embodiments described above by agitator rotation make washings along the inclined plane when upper and lower moves up, the direction of rotation of itself and agitator is rotated equidirectionally.Moving of the above-below direction of washings is big more, can reach cleaning strength raising and shortening drying time, the minimizing of dry fold more.In addition, because the sliding action of the agitator of the respective embodiments described above and washings is bigger, so, also can further improve cleaning strength by small concavo-convex and vanelets is set on the surface, inclined plane.
Figure 10 represents to see that from top (from blade face one side) vertical view (A) of the agitator of Fig. 2 and Fig. 6 and the height (B) of blade surface reach (C) as typical example.(B) and (C) be illustrated among (A) figure, be respectively on the radial location of R1, R2, R3 the height change of the blade surface that makes progress in week at radius from pivot.
(B) situation of the agitator 4 of figure presentation graphs 2, on this agitator 4, inclined plane 4b is the plane, if but the height change of the blade surface on the Zhou Fangxiang is illustrated, then on each radial location, produced highly the highest top (H1, H2, H3) as can be known.If these tops are upwards connected half, can know to form ridge portion that this ridge portion uprises to periphery gradually from pivot.So, even if on the agitator 4 of Fig. 2, except valley portions 4c, also top and ridge portion can be defined.
(C) situation of the agitator 50 of figure presentation graphs 6.When being the agitator 50 of Fig. 6, need not illustrate the blade surface height that makes progress in week, also can find out valley portions 50c, top 50d, the 50e of ridge portion at an easy rate from the surface configuration of agitator.
In a word, can know that by Figure 10 valley portions, top and ridge portion uprise to periphery gradually from pivot.Can learn in addition, on each radial location, with respect to blade surface height H (H1, H2, H3, H4, H5, H6), the circumferential lengths on inclined plane (circumferential length) L (L1, L2, L3, L4, L5, L6) becomes respectively greatly, forms little and mild inclined plane, inclination angle.
Figure 11 is the moving and the relation of cloth between twining of above-below direction of the angle of inclination of representing experimental investigation inclined plane qualitatively (with respect to the angle of the direction of rotation of agitator) and washings.The mobile angle of inclination with the inclined plane of the above-below direction of washings increases pro rata, but can welcome peak value on certain angle, surpasses this and then reduces on the contrary.Can know thus has the optimum tilt angle.This be because, if the angle of inclination is excessive, then washings is tilted face and pushes, and is difficult to slide on the surface of agitator, move the top that is difficult to the inclined plane.
On the other hand, when become or surpass washings move up and down the angle of inclination that begins to reduce the time, cloth twines sharply to be increased.This is because if the angle of inclination is excessive, and then washings is difficult to slide on the surface of agitator, and the valley portions on the inclined plane becomes the wad shape, the shape that rolls motion.
According to experiment, when being the relative tilt face of Fig. 2 and Fig. 6, the angle of inclination is preferably 15～25 °.At this moment, the difference of height on inclined plane becomes about 0.13～0.22 times of stirrer diameter.In addition, when being the single inclined plane of Fig. 8, the angle of inclination is preferably 15～30 °
According to above-mentioned embodiment, owing to only rotate around rotating shaft merely by agitator, the washings one side is slided on agitator, one side moves up at the upper and lower of washing and dewatering bucket, simultaneously, rotate with the direction of rotation of agitator equidirectionally, so washings 38 can not become the wad shape, washings 38 is difficult to twine, twist around.Thus, the fold that can suppress washings 38 produces, and can increase substantially dry finishing.In addition, can prevent to twine the generation of the uneven drying that causes.
The agitator of above-mentioned patent documentation 2 is to be provided with in washtub with the tabular surface of impeller rotating shaft oblique on impeller, by making this tabular surface around the impeller shaft rotation, produce pulse in the water in washtub, the agitator surface is the inclined plane, the agitator (Fig. 8) of this and above-mentioned embodiment is similar, but because agitator is one jiao of the bottom (diameter of agitator is little) that is configured in washtub, so can not be with the mobile washings that offers of above-below direction.Certainly, even if the agitator of patent documentation 2 is used on scrubbing-and-drying unit, do not have water in the washtub in the time of also can be owing to drying, a washings only part is active, can not make the washings drying.
The agitator of patent documentation 3 is provided in the inner bottom part of washing machine, from the outside perimembranous general radial of central authorities be provided with the blade of a plurality of one-tenth fan-shapeds, at least one blades height is than other blades height height in these blades, simultaneously this high blade possess from by the center to roughly 2/3 the position of periphery to the mild rake that tilts downwards of outer side Monday, and will set 1.5～2 times at the width that the width of the peripheral part of high blade is compared the peripheral part of low blades.
The agitator shape of patent documentation 3 is for blade is contacted with washings interimly, and for reducing the heavy burden of the external peripheral zone that is applied to blade, prevents the shape that the torque of motor increases.The blade that is seen as fan-shaped from top is similar with the agitator (Fig. 6) of above-mentioned embodiment., from laterally, blades height is roughly certain from central authorities to the peripheral part, and the present invention who uprises with perimembranous outward is different.In addition, because the extended corner of fan-shaped is littler than the present invention significantly, the size of blade is also little, so the circumferential inclination of blade is rapid.That is: in the occasion of the agitator of patent documentation 3 rotation, moving of washings with similar at agitator illustrated in fig. 12, moving of the above-below direction of washings almost do not have, and washings is pushed to the direction of rotation of agitator by blade, easily become the wad shape on agitator, Yi Fashengbu twines.Therefore, even if the agitator of patent documentation 3 is used on scrubbing-and-drying unit, also can only obtain the same dry finishing of agitator with Figure 12 explanation.
About the washings in the washing procedure move and clean effect, being example with 60 of the agitator of Fig. 6 describes with reference to the ideograph of Figure 14 and Figure 15.Figure 14 is that expression launches agitator 60 at circumferencial direction, the moving of the above-below direction of each the circumferential locational washings 70 on this agitator 60, and Figure 15 is that agitator 60 is seen in expression from the top, circumferential the moving of the washings 70 on the agitator 60.Moving with the principle of cleaning strength generation of each locational washings 70 is as follows.
(1) part (position of (a) in Figure 14) of the circumferential inclined plane rise of protrusion 74a (50b, 50e)
The rate of rise by protrusion 74a is lifted washings 70a repeatedly from following, compress washings 70a thus repeatedly, produces the cleaning strength of pushing cleaning function.
(2) surpass the part (position of (b) among Figure 14) on the summit of protrusion 74a
The washings 70b that the rate of rise by protrusion 74a is lifted upward upsprings in the position that surpasses protrusion 70a, and this protrusion 74a between produce the gap.In addition, at this moment, circumferential speed increases, and produces the gap at (between washings 70a and the washings 70b and between washings 70d and the washings 70e) between the washings of adjacency that makes progress in week.Enter these gaps from the high washings of detergent concentration of top spray, soak into the inside of washings 70 effectively.Thus, even if keep the state of the top water level that is no more than agitator 60, washings also can spread all over washings 70 integral body.
(3) part that descends from the inclined plane of protrusion 74a is to the part (position of (c) Figure 14) of valley portions 74d (50c)
The washings 70c that upsprings on protrusion 74a drops to the position of valley portions 74d by the descending slope from protrusion 74a, produces by the cleaning strength of compressing and washing and beating the effect of washing.At this moment, also produce and the conflicting of the slow adjacent washings 70d of circumferential speed, week washings 70 forwards, backwards also produce by the cleaning strength of compressing and washing and beating the effect of washing each other.And then the washings that infiltrate in the washings 70 are forced out with dirt.
(4) travel direction of the above-below direction of washings 70 be opposite part (among Figure 14 (b) and (c) between and (c) and (a))
The direction of motion of the washings 70c of the washings 70b that upsprings by protrusion 74a and the washings 70c of whereabouts and whereabouts and the washings 70a that is lifted is for oppositely, washes rubbing of same motion and washes effect generation cleaning strength by rubbing with the hand that makes the mutual counter motion washing of washings with two hands.
In addition, in order to bring into play the clean effect of above-mentioned (1)～(4) to greatest extent, for the desired size of agitator 60, the rotary speed that is preferably agitator 60 is decided to be 130～140rpm.When rotary speed is slower than it, might diminish by the mobile of washings 70, clean effect may reduce.And, when rotary speed is faster than it, might can not follow moving up and down of agitator 60 surfaces by washings 70, the mobile of this washings 70 diminishes, and clean effect may reduce.
So, the enough considerably less washings of clean energy that one side makes agitator 60 rotation one sides that the high washings circulation of detergent concentration is carried out are brought into play by compressing and washing, beating compoundly wash, rub and wash this three effects simultaneously, obtain high cleaning strength.
The motion of the washings 70 that this agitator 60 causes also is suitable for rinsing process.Because washings enter upspring gap between the washings that produces of washings easily, and permeate in this washings 70, so washings and detergent ingredients that available same effect will be infiltrated in the washings 70 extrude the raising rinse efficiency.
In addition, on drying process, also be fit to.Because warm braw enters upspring gap between the washings that produces of washings, so warm braw not only can also spread all over the inside of this washings at the outer surface of washings, promotes water evaporates, improves drying efficiency.And then the motion that cloth twines few washings has realized the drying that fold is few.
