The upper surface of rotating vane dish 11 consists of a plurality of protrusion 11a and the 11b of paddy section that is formed between the plurality of protrusion 11a.In present embodiment example 1, possess two protrusion 11a that form across the pivot P of rotating vane dish 11 and be formed on two 11b of paddy section between this protrusion 11a.The maximum of this rotating vane dish 11 is characterised in that protrusion 11a and the 11b of paddy section are tortuous (crawling).Ground forms from pivot P to the radius r general radial for protrusion 11a and the 11b of paddy section, than radius r, by outer circumferential side, on a direction, is being bent into roughly circular-arc.That is, protrusion 11a and the 11b of paddy section observe and are roughly S word shape from top, and left and right is asymmetric, with respect to pivot P, is point symmetry.Mean the amount of bow of protrusion 11a with the outermost perimembranous from crest line 11a1 to the angle θ 1 of center line IV-IV, be shown in the windup-degree θ 7 of crooked outermost perimembranous with the angle measuring gauge of the tangential direction of the outermost perimembranous of crest line 11a1 and radial direction.In addition, the outermost perimembranous with the lowest point 11b1 from the line of single-point among Fig. 4 expression means the amount of bow of the 11b of paddy section to the angle θ 2 of center line V-V.In addition, rotating vane dish 11 rotatings (left/right rotation), so bending direction can be reverse with present embodiment example 1.

As shown in Figure 5, protrusion 11a forms highly and uprises gradually to peripheral direction from pivot P.Be illustrated in the angle of inclination of the crest line 11a1 of the protrusion 11a meaned with double dot dash line in Fig. 4 apart from horizontal plane with θ 3.The peripheral end face 11f of protrusion 11a is so that the inclined plane that the mode that topple over to central side on top tilts means its angle of inclination with θ 6.In addition, as shown in Figure 6, the 11b of paddy section approximate horizontal.In present embodiment example 1, for rotating vane dish 11 being fixed on washing dehydration drive unit described later, bellying 11i upward is set around pivot P, guarantee the space of folding and unfolding hold-down screw, in order to be connected swimmingly with the 11b of paddy section, to form, make the 11b of paddy section slightly low to the peripheral direction height.

In addition, at length the shape of the circumferencial direction of the upper surface of rotating vane dish 11 is described.Fig. 7 (b) is that the r1 of radial location arbitrarily meaned with single-point in Fig. 7 (a) line along the circumferential direction dissects, the cutaway view that the intersection point of crest line 11a1 and radial location r1 of take launches on the L direction as benchmark.The crest line 11a1 of protrusion 11a is connected with inclined plane 11g, 11h smooth on direction of rotation swimmingly with the lowest point 11b1 of the 11b of paddy section, and the upper surface of rotating vane dish 11 along the circumferential direction forms tortuous (う ね り) on above-below direction.The maximum inclination angle that means inclined plane 11g with θ 4, with the maximum inclination angle of θ 5 expression inclined plane 11h.The angle of inclination on the inclined plane from the lowest point 11b1 to crest line 11a1 becomes greatly gradually from 0 degree, becomes maximum inclination angle θ 4, θ 5, and when near crest line 11a1, angle of inclination diminishes gradually, at crest line 11a1, is 0 degree.

In addition, with respect to the difference of height H1 of crest line 11a1 and the lowest point 11b1, the circumferencial direction length L 1 of inclined plane 11g, 11h from crest line 11a1 to the lowest point 11b1 is longer.With regard to the height H 1 of protrusion 11a, radius r 1 is higher the closer to periphery, and circumferential length L is also elongated pro rata with radial location r1, so tilt angle theta 4, θ 5 and radial location r1 are irrelevant, is roughly certain.Therefore, the ratio of L1 and H1 and radial location r1 can't, be roughly certain.

Then, the shape of the radial direction of the upper surface of rotating vane dish 11 described.Fig. 7 (c) is the circumferential locations at the A to F from shown in Fig. 7 (a), from pivot P, at radial direction, dissects and the cutaway view that means.The downside of figure is pivot, and upside is peripheral part, and right side is the upper surface of rotating vane dish 11.Near the 11b of paddy section of A section, be the gradient slightly downward towards outer circumferential side.Along with near B section, C section and protrusion 11a, become the upgrade towards outer circumferential side, this gradient is steeper the closer to periphery.And, in D section, roughly along crest line 11a, towards peripheral direction, be therefore upgrade in inner circumferential side, but lean on outer circumferential side at the intersection point Q than with crest line 11a1, highly be roughly necessarily, be roughly level.In E section, in inner circumferential side, be upgrade, in the middle of roughly, outer circumferential side is descending slope.In F section, in inner circumferential side, approximate horizontal, and outer circumferential side is from being the gradient slightly midway.

The movement of the washings during to the washing/drying of the occasion of the rotating vane dish 11 that used the present embodiment example describes.When 11 rotation of rotating vane dish, the washings on this rotating vane dish 11 slides and rotates on the direction of rotation of rotating vane dish 11 on one side on one side on rotating vane dish 11, and is pushed by protrusion 11a, on above-below direction, vibrates.Now, because the inclined plane 11h of protrusion 11a is different from the surface configuration of the radial direction of 11g, therefore, according to the direction of rotation of rotating vane dish 11, moving of washings is different.

In Fig. 4, in the situation that rotating vane dish 11 is turned right, washings is tilted face 11h and pushes away upward.As shown in Fig. 7 (c), the gradient of the radial direction of inclined plane 11h is the closer to periphery and the closer to steeper on the top of protrusion 11a, so upward mobile of washings become large, but is difficult to the periphery side shifting.In addition, because the inclined plane 11h of protrusion 11a is crooked inboard, so the normal of inclined plane 11h is towards the inboard, top of washing and dewatering groove 9.Therefore, when rotating vane 11 is turned right, as shown in the arrow S of Fig. 7 (a), inclined plane 11h produces the effect that washings is drawn in to the inside.

On the other hand, in the situation that rotating vane dish 11 turns left, washings is tilted face 11g and pushes away upward.The gradient of the radial direction of inclined plane 11g, when near periphery, is level or the downward gradient.In addition, the normal of inclined plane 11g is towards the upper outer of washing and dewatering groove 9.Therefore, washings is released laterally as shown in the arrow T of Fig. 7 (a).

Like this, washings when rotating vane dish 11 is turned right easily to washing and dewatering groove 9 by central mobile, when rotating vane dish 11 turns left easily to the internal perisporium side shifting of washing and dewatering groove 9.

Fig. 7 (a) schematically means this pattern.When rotating vane dish 11 is turned right, be positioned at radial location r1 with ◆ the washings that symbol U means is tilted face 11h mentions inboard upward, surpasses the top, top of protrusion 11a and moves to than radial location r1 on the inclined plane 11g meaned with ◇ symbol U' in the inner part.In addition, when rotating vane dish 11 turns left, the washings meaned with the ■ symbol that is positioned at radial location r1 is tilted face 11g mentions in the outside upward, surpasses the top, top of protrusion 11a, moves to than radial location r1 on the inclined plane 11h meaned with symbol V' in the outer part.

Like this, by right-hand rotation and the left-hand rotation that alternately is rotated fan disk 11, the replacement of the cloth of the radial direction of the washings in promotion washing and dewatering groove 9.Thus, be in the suds, can realize effect that mechanical effect (rinse action, by the effect of washing, the effect of washing by rubbing with the hands) spreads all over, wash uneven minimizing, the raising of cleaning force.In addition, in drying, warm braw spreads all over washings equably, can realize minimizing, consumes power, the reduction of drying time of uneven drying.But, with regard to the movement of the washings of circumferencial direction, slightly few during than right-hand rotation when turning left.This be because, when turning left, be positioned at the action that the washings of the outer circumferential side of inclined plane 11g pushed laterally large, to the mobile of direction of rotation, reduce.In the present embodiment, due to the water level of the washings of the degree of the upper surface being no more than rotating vane dish 11, on one side from washing and dewatering groove 9 the direction washings scatter washings and washed on one side, it is important therefore making washings spread all over washings.Therefore, as long as make washings mobile on circumferencial direction and radial direction in washing and dewatering groove 9.That is, preferably make the movement of washings of circumferencial direction roughly the samely mobile in the left rotation and right rotation of rotating vane dish 11.Like this, be difficult to produce the bias of washings in washing and dewatering groove 9.So, in the present embodiment example, roughly the same for the movement of the circumferencial direction that makes washings in the left rotation and right rotation at rotating vane dish 11, and ridge 11d described later is set.

The rotating vane dish 11 of present embodiment example, with respect to the washing and dewatering groove 9 of the internal diameter size of about 520mm, is configured to and makes outside dimension be approximately large footpath 470mm.This be because, even the angle of inclination of inclined plane 11h, the 11g of protrusion 11 is identical, the outside dimension of rotating vane dish 11 is larger, more can make the height of protrusion 11 higher, the mobile of the above-below direction of washings becomes large, thereby can improve cleaning force.

In the rotating vane dish 11 of this size, the desired size that size to each one, the result that shape is carried out experimental research obtain is described.

The difference of height H1 of crest line 11a1 and the lowest point 11b1 is larger, and washings is larger in the vibration of above-below direction.But, when making H1 excessive, the gradient steepening of inclined plane 11h, 11g, therefore, when surpassing certain angle, washings is difficult to slide on rotating vane dish 11, and washings is tilted face 11h, 11g pushing and rotation together with rotating vane dish 11.If like this, washings diminishes in the vibration of above-below direction, and cleaning force descends.Therefore, the treble height of expectation protrusion 11a is 65～70mm, maximum inclination angle θ 4, the θ 5 of the 11h of inclined plane smoothly, the 11g of the direction of rotation of this protrusion of expectation formation 11a are with respect to the horizontal plane 15～25 degree, and the tilt angle theta 3 of the radial direction of the crest line 11a1 of expectation protrusion 11a is with respect to the horizontal plane 10～20 degree.

θ 4 and θ 5 are so long as, in above-mentioned scope, can be different values.Like this, when turning right when turning left, the washings of the vibration of above-below direction, direction of rotation or radial direction mobile different.For example, if making θ 4 is 15 degree, make θ 5, be 20 degree,, when rotating vane dish 11 is turned right, the mobile of the up-down vibration of washings, direction of rotation becomes large, and cleaning force uprises.Therefore, for example, if there is the electric washer of mechanism's (pollution detections of the washings that the muddiness of the washings that undertaken by photoelectric sensor detects, undertaken by conductivity sensor) of the pollution that detects washings, be judged as the many occasions of pollution, rotational time when rotational time ratio when rotating vane dish 11 is turned right turns left is long, or makes rotary speed high.On the contrary, be judged as the occasion that pollution is few, rotational time when rotational time ratio when rotating vane dish 11 is turned right turns left is short, or makes rotary speed low.By like this, the occasion identical with θ 5 with θ 4 compared, and can realize the movement of meticulousr washings.But, when switching rotation in left rotation and right rotation, when the movement of washings, especially during circumferencial direction mobile different of washings, become that cloth is wound around, the main cause of cloth bias, therefore preferably θ 4 is substantially the same with θ 5.

The amount of bow of protrusion 11a is larger, and when rotating vane dish 11 is turned right, the effect that washings is drawn in to the inside is larger.But, when amount of bow is excessive, the surface configuration of the radial direction of inclined plane 11h becomes the U word groove shape of steep gradient at outer circumferential side, and therefore the vibration of the above-below direction of the washings on rotating vane dish 11 reduces, rotation together with rotating vane dish 11, cause cleaning force to descend.In addition, when rotating vane dish 11 turns left, due to the surface configuration of the radial direction of the inclined plane 11g chevron that is the word of falling U shape, therefore the vibration of the above-below direction of the washings on rotating vane dish 11 reduces, the washings of outer circumferential side is pushed consumingly to the sidewall of washing and dewatering groove 9, hindered the movement of washings.In addition, when the windup-degree θ 7 of the most peripheral of the crest line 11a1 at protrusion 11 is excessive, crooked curvature diminishes, and the effect that washings is drawn in to the inside reduces.And the beginning radial location r of the bending of protrusion 11a is the closer to periphery, the effect of more washings being drawn in to the inside, going out to the periphery thruster reduces.Due to above reason, the amount of bow θ 1 of expectation protrusion 11a is 20～25 degree, and the windup-degree θ 7 that is desirably in crooked outermost perimembranous is 45～55 degree.In addition, the beginning radial location r of the bending of expectation protrusion 11a than the radius of rotating vane dish 11 1/2 in the inner part.

The amount of bow θ 2 of the 11b of paddy section is set as identical with the amount of bow of protrusion 11a, but also can be different.For example, when the amount of bow θ 2 that makes paddy section is larger than the amount of bow θ of protrusion 11a 1, angle of inclination 5 θ of the circumferencial direction of inclined plane 11h diminish, and the tilt angle theta 4 of inclined plane 11g becomes large.As a result of, as mentioned above, washings movement during with left-hand rotation when rotating vane dish 11 is turned right is different.

In addition, when the revolution of rotating vane dish 11 is too high, the effect of utilizing centrifugal force that washings is released laterally is stronger than the effect that above-mentioned washings is drawn in to the inside, and the mobile of the washings of radial direction worsens.Therefore the expectation of the revolution of rotating vane dish is per minute 100～130 right sides of turning left.

Mild (full front of a Chinese gown open country) zone (11b of paddy section) at protrusion 11a has a plurality of ridge 11d crooked on the direction identical with protrusion 11a.Crooked shape and protrusion 11a are roughly the same.In the present embodiment example, as shown in Figure 4, in the position across the lowest point 11b1 equal angular, configure one by one the inner circumferential side of ridge 11d, and be located at respect to the point-symmetric position of pivot P (amounting to four).When making 11 rotation of rotating vane dish, washings is on one side in upper surface slide one side of rotating vane dish 11 up-down vibration, so ridge 11d generation washboard effect, has the effect that improves cleaning force.But when the excessive height of ridge 11d, identical with the stirring vane (bobbing machine) of general electric washer, the effect of catching on washings becomes large, become that cloth is wound around, the main cause of cloth damage.Therefore, in order not hinder the slip of washings, the height of expectation ridge 11d is 2～4mm.The mild zone (11b of paddy section) that ridge 11d is arranged on to protrusion 11 is in order to reduce the damage of washings.On the top of protrusion 11a near zone power that washings is pushed away upward large, so during near the region division ridge 11d on the top at protrusion 11a, ridge 11d becomes the main cause that makes the washings strong friction and damage.

Then, to utilizing ridge 11d that the roughly the same method in mobile left and right of the circumferencial direction of washings is described.Fig. 8 is the cutaway view of the circumferencial direction of ridge 11d.The surface configuration of ridge 11d makes upper surface for semicircle shape roughly for washings is difficult to hook, with inclined plane 11d1, the 11d2 of left and right, be connected swimmingly.And, make left side face 11d1 larger than the tilt angle theta 8 of inclined plane, right side 11d2 apart from the tilt angle theta 9 of level.By like this, when rotating vane dish 11 turns left when turning right the slip of washings on rotating vane dish 11 tail off, the mobile of the direction of turning left becomes large.Thus, can make the movement of the circumferencial direction of washings when left rotation and right rotation that produced by the bending of protrusion 11a roughly the same.Certainly, when making θ 9 excessive, the effect that can produce the hook washings, therefore expect that θ 9 is 50～60 degree.In addition, θ 8 is as long as produce washboard effect, as long as therefore be set as 20～40 degree degree.

In addition, roughly the same in left rotation and right rotation in the movement of circumferencial direction in order to make washings, also can make the bending direction of the bending direction of ridge 11d and protrusion 11a reverse.

In addition, projection 11d can be set, but make the tilt angle theta 4 of inclined plane 11g larger than the tilt angle theta of inclined plane 11h 5.In addition, can make the amount of bow θ 2 of the 11b of paddy section than the amount of bow θ of protrusion 11a 1 large (for θ 4>θ 5)

In addition, identical in the tilt angle theta 4 that makes inclined plane, θ 5, make amount of bow θ 2 occasion identical with the amount of bow θ 1 of protrusion of paddy section, while turning left in order to increase washings in the movement of circumferencial direction, the rotational time of the rotational time of the rotating vane dish 11 while making the rotating vane dish 11 when turning right is long, or the rotary speed of the rotating vane dish 11 of the rotary speed of the rotating vane dish 11 while making when turning right is high.

The bellying 11e that possesses a plurality of spherical crown shapes at the upper surface of rotating vane dish 11.Bellying 11e is configured to be dispersed in the part beyond zone on the top of protrusion 11a.This bellying 11e also produces the washboard effect identical with above-mentioned ridge 11d, has the effect that improves cleaning force.But, when the excessive height of bellying 11e, the slip of washings reduces, and rotation together with rotating vane dish 11.Like this, washings diminishes in the vibration of above-below direction, and cleaning force descends.Therefore, in order not hinder the slip of washings, the height of expectation bellying 11e is 1～3mm, and diameter is 20～30mm.In addition, in the present embodiment, number is 30.

Upper surface at rotating vane dish 11 possesses a plurality of through hole 11c for water flowing and ventilation.Through hole 11c is configured to be dispersed in the part beyond zone and ridge 11d, bellying 11e on the top of protrusion 11a.When 11 rotation of rotating vane dish, as mentioned above, the washings on rotating vane dish 11 slides on one side on rotating vane dish 11, on the direction of rotation of rotating vane dish 11 rotates on one side, and boosted by protrusion 11a, thereby vibrates on above-below direction.By this slip, between washings and rotating vane dish 11, form moisture film.The thickness of moisture film brings impact to the rotary load torque acted on from washings rotating vane dish 11, and moisture film is thinner, and the rotary load torque more increases.With regard to the thickness of moisture film, the quantity of through hole 11c is more, and thickness is thinner.On the other hand, the power that washings is boosted upward is in the top of protrusion 11a upper area maximum, so the size of the thickness of the moisture film of this part is brought considerable influence to the rotary load torque acted on rotating vane dish 11.That is, embodiment as shown in Figure 4 is such, and in the top of protrusion 11a upper area does not have the mode of through hole 11c, the section zone forms thicker moisture film atop, and the rotary load torque therefore acted on rotating vane dish 11 from washings reduces.In addition, because be difficult to cause the direct slip of rotating vane dish 11 and washings, therefore also reduced the damage of the washings produced.

Washing and dewatering groove 9 bottom of peripheral wall surfaces within it possesses for masterpiece upwards is used near on the washings of this internal perisporium face and prevent the bias of this washings and the lifter 35 of cloth winding.As Fig. 9 and Figure 10 in detail as shown in, this lifter 35 possesses: the upper surface by the bellying 35a that is positioned at the height relative with rotating vane dish 11 and gives prominence to from internal perisporium towards the inner arc shape forms, and tilts and the inclined plane 35b of the chevron of extending in the mode uprised successively in a circumferential direction along this internal perisporium face; And with part the top of the inclined plane 35b from circumferencial direction upwards state mode that the inboard of internal perisporium face bloats along this internal perisporium face at the vertical ridge 35c of (make progress) extension.Inclined plane 35b is identical height and the angle of inclination of the height on inclined plane and angle of inclination smoothly on direction of rotation with the protrusion 11a that forms rotating vane dish 11.In addition, ridge 35c bloats height (thickness) for the height roughly the same with the bellying 35a of lifter 35, and expectation is 10～15mm.When bloating of this ridge 35c is highly excessive, in washing procedure, the effect of the movement of the circumferencial direction of the rotation of inhibition washings accompanying rotation fan disk 11 is excessive, and cleaning is brought to harmful effect.This lifter 35 forms integratedly by resin forming and installs.

In addition, expect to divide for the external end edge on the top, top of the protrusion 11a at rotating vane dish 11 and the 35bDe Ding top, inclined plane of lifter 35 structure that can guarantee the gap g1 more than about 25mm between both opposite edges when relative.In addition, more than the gap g2 that expectation is configured to the inner surface of the external end edge on top, top of protrusion 11a of rotating vane dish 11 and washing and dewatering groove 9 can guarantee 30mm.Therefore, the tilt angle theta 6 of the peripheral end face 11f of the protrusion 11a of expectation rotating vane dish 11 is 7～15 degree with respect to vertical plane.

These values are suitable for improving the washing with respect to washings, dry efficiency, and prevent nip (the hereinafter narration) of washings.That is, the top, top of the protrusion 11a of rotating vane dish 11 is positioned at the movement that the outside can increase washings, be conducive to washing, drying, but the gap between rotating vane dish 11 and lifter 35 and washing and dewatering groove 9 is little, and washings is easily nipped.

Figure 11 is in order to mean the relativeness of rotating vane dish 11 in washing and dewatering groove 9 and lifter 35, to dissect the stereogram that washing and dewatering groove 9 means with the part of rotating vane dish 11.In this embodiment, on rotating vane dish 11 with spaced two protrusions of 180 degree, at the periphery wall inner surface of washing and dewatering groove 9 also with spaced two lifters 5 of 180 degree.

The lifter 35 formed like this is in washing procedure, at washings, fall and moistening washings is come under the state on rotating vane dish 11 at once, when rotating together with rotating vane dish 11 with one side, when the mode of utilizing centrifugal force to be pushed to the internal perisporium face of washing and dewatering groove 9 on one side moves, inclined plane 35b due to lifter 35, masterpiece upwards is used on washings, and, utilize ridge 35c to suppress rotation.And, utilize other washings of sending here successively, along the internal perisporium face rising of washing and dewatering groove 9, and drop to the center position of rotating vane dish 11.Therefore, in the situation that rotating vane dish 11 is turned right, utilize the effect of crooked protrusion 11a, washings easily to washing and dewatering groove 9 by central mobile, in the situation that rotating vane dish 11 turns left, utilize the effect of crooked protrusion 11a, be pushed to washing and dewatering groove 9 the internal perisporium side washings as mentioned above, in the mode of the central side that returns to washing and dewatering groove 9, move.Therefore, by lifter 35 is set, further promote the movement of washings at radial direction.

In addition, on peripheral end face 11f by the protrusion 11a at rotating vane dish 11, suitable tilt angle theta 6 is set, guarantee the suitable interval between the internal perisporium face of the bellying 35a of the peripheral end face 11c of above-mentioned rotating vane dish 11 and lifter 35 and washing and dewatering groove 9, and when washings will enter the gap between the peripheral end face 11c of protrusion 11a of the bellying 35a of lifter 35 and rotating vane dish 11, the mode effect of the inclined plane 35b of bellying 35a so that washings is released upward, can prevent that washings from nipping gap and rotating vane dish 11 can't be rotated, damage washings owing to nipping.In addition, the internal perisporium face of the bellying 35a of lifter 35 is flexure plane cylindraceous, gap between the peripheral end face 11f of the protrusion 11a of rotating vane dish 11 and the bellying 35a of lifter 35 is certain in a circumferential direction, even therefore washings enters this gap, also former state is by gap, the gap of can not nipping.

In addition, in drying process, rotating vane dish 11 is acted in the following manner with lifter 35: untie the washings of being partial to the internal perisporium face of washing and dewatering groove 9 due to final dewatering, utilize the inclined plane 35b of lifter 35 promote washings up to movement, and utilize ridge 35 to suppress the movement of washings at direction of rotation (circumferencial direction), promote the replacement of washings, make circulating air well improve drying efficiency with contacting of washings.

Figure 12 is the block diagram of the control part of scrubbing-and-drying unit.The 40th, microcomputer, be connected with action button input circuit 41, level sensor 21, temperature sensor 26, vibrating sensor 27 on being connected to each switch 6,6a, accept user's push-botton operation, the various information signals in washing procedure, drying process.Be connected with drive circuit 42 from the output of microcomputer 40, and be connected with water supply electromagnetic valve 4, clutch 12, draining valve 15, circulating pump 16, motor 13, Air Blast fan 19, heater 20 etc., control their switching, rotation, energising.In addition, with 7 sections light emitting diode indicators 25, light emitting diode 7, the buzzer 43 of operating state for to user's signalled washing machine, be connected.

In the electric washer of this embodiment, with regard to the water level of the washings of the bottom being stored in water jacket 10 in washing procedure and washings, basically under the state while making 11 rotatings of rotating vane dish that washings are circulated, the washings that must avoid being stored in the bottom of water jacket 10 surpass the upper surface of rotating vane dish 11 significantly, rise to significantly so that the mode that the washings on this rotating vane dish 11 swims is flooded such water level.But, after washings on rotating vane dish 11 contains a large amount of washings, when state that the circulation that maintains for a long time the rotation that makes rotating vane dish 11 and washings stops, washings in the washings that washings is contained and washing water circulation system utilize under gravity current, and be stored in the bottom of water jacket 10, therefore the water level under this state is allowed the upper surface that surpasses rotating vane dish 11.

Therefore, in this embodiment, as the designated water level for water management for washings, in the washing of the washings of common cloth amount, setting is than the slightly low water level h1 of height of the lower surface of the rotating vane dish 11 in washing and dewatering groove 9, in the washing of the washings of the few cloth amount lower than common cloth amount, set (approximately 10cm left and right) high water level (with De Zui high-order bit, top, the top water level about equally of the protrusion 11a of rotating vane dish 11 in washing and dewatering groove 9) h2 slightly than above-mentioned water level h1.

And, in the water supply operation, the water of supplying with ormal weight dissolves the powder detergent according to the amount input of washings, generates the washings of high detergent concentration.In washing procedure, by making under the state that washing and dewatering groove 9 is static, the mode of falling on washings with the washings of the high detergent concentration of the bottom while 11 rotatings of rotating vane dish being made be stored in water jacket 10 circulates, protrusion 11a is by rotating, its surface moves up and down, washings by repeatedly boosting the washings that contain high detergent concentration also makes its vibration, is washed.

In rinsing process, utilize the washings with the identical water level of washing procedure, by making under the state that washing and dewatering groove 9 is static, to make 11 rotatings of rotating vane dish on one side, making on one side to be stored in the mode that the washings of the bottom of water jacket 10 fall on washings circulates, on rotating vane dish 11, make the washings that contains washings move up and down, extruded the rinsing of washings.

In drying process, circulation in the following manner: on one side by the rotating of rotating vane dish 11, stir the washings in the washing and dewatering groove 9 be centrifuged after dehydration, moistening air in the water jacket of sucking-off on one side 10, heating after the water-cooled dehumidifying, and be blown in washing and dewatering groove 9.

When pressing power switch 5 and switching on power, above-mentioned microcomputer 40 startings, carry out the washing shown in Figure 13 and Figure 14 and dry basic control handling procedure.

Step S107

When supplying water the detergent dissolution water level, stop supplying water.In this embodiment, independently the washing agent output is set as to about decaliter with detergent amount (cloth amount).This water yield be after detergent dissolution operation (step S108) in, when making 9 rotation of washing and dewatering groove, the sufficient water yield the water that the bottom that is stirred in washing and dewatering groove 9 is supplied with and washing agent, and be set as the water surface than the height of the lower surface of rotating vane dish 11 low (washings does not soak before detergent dissolution).

Step S108

By making washing and dewatering groove 9 and rotating vane dish 11 low speed rotation (approximately per minute 70 turn) in one direction integratedly, detergent dissolution water and the powder detergent of the bottom of putting into water jacket 10 are stirred in execution in the bottom surface of this washing and dewatering groove 9, generate the detergent dissolution of the washings of high detergent concentration.The one minute time of detergent dissolution is just enough.Even low temperature (low water temperature) is difficult under the condition of the powder detergent that dissolves also the dissolution rate for about 90%.The detergent concentration of the washings that generate is approximately 7 times.At this, normal concentration is the ratio of the powder detergent amount 20 grams/washing water yield three decaliters.

Step S109

Carry out pre-wash.This pre-wash is carried out indirectly in the stirring that makes to make under the state that washing and dewatering groove 9 is static 11 rotatings of rotating vane dish, in the rotating of rotating vane dish 11, by making circulating pump 16 runnings, the washings of the bottom of water jacket 10 are fallen washings from nozzle 34.In rotating vane dish 11 and circulating pump 16 stopping periods, with reference to the detection signal of level sensor 21 on one side open washing agent water supply electromagnetic valve and washing water supply electromagnetic valve on one side, the mode that is no more than designated water level with water level is carried out moisturizing.Carry out this running by repeated multiple times, washings is immersed in washings, and is distributed on rotating vane dish 11.

When rotating for the first time, the washings that detergent concentration is about 7 times are fallen on washings, and are impregnated in this washings.The washings of high concentration spread to washings from nozzle 34, therefore utilize the penetrant action of washing agent, soak into equably washings.The oily solvability of washings of high concentration of having soaked into washings is high, makes the effect that oil contamination dissolves and dirt floats from washings very large, thereby obtains higher cleaning force.

By make-up water repeatedly, the detergent concentration of falling the washings on washings descends, and in the pre-wash ending phase, becomes the twice left and right of normal concentration.

Step S110

Carry out formal washing.In this formal washing, at first, revise and utilize method same as described above to carry out the detection of cloth amount and the wash time set and setting.Afterwards, make under the state that washing and dewatering groove 9 is static, while making 11 rotatings of rotating vane dish make circulating pump 16 running, repeatedly carry out by be stored in water jacket 10 bottom washings from nozzle 34 fall stirring that the washings of washings circulate about two minutes, the cloth that makes 11 rotatings of rotating vane dish that carries out about one minute under the running that stops circulating pump 16 state that the circulation of washings is stopped unties stirring.By the rotating of rotating vane dish 11, washings substitutes in washing and dewatering groove 9 on circumferencial direction and radial direction, is not cleaned with omitting.Finally, in the running that stops circulating pump 16 homogenising that makes 11 rotatings of rotating vane dish that stops carrying out about one minute under the state of circulation of washings, stir, finish formal wash time.

Step S111

Carry out primary storage rinsing.Store in rinsing at this, at first, after opening draining valve 15 and discharging the washings of the bottom that is stored in water jacket 10, make rotating vane dish 11 and washing and dewatering groove 9 rotation in one direction integratedly, make the contained washings centrifugal dehydration of washings.It is identical with the rotary speed (approximately 1000rpm) of final dewatering described later that washing and dewatering groove 9 during the dehydration of this washings and the rotary speed of rotating vane dish 11 are set as, and the higher dehydration rate with realization that turns round of dewater.

Afterwards, on one side close drain solenoid valve 15 and make washing and dewatering groove 9 and rotating vane dish 11 low speed rotation (35～40rpm) in one direction integratedly, to open a mode that washing water supply electromagnetic valve make running water from watering mouth fall washings rotating vane dish 11 on supplied water on one side.

Then, under the state stopped in the rotation that makes washing and dewatering groove 9 with rotating vane dish 11, the mode that is no more than designated water level with the water level of the bottom of water jacket 10 is carried out washings water supply.

Then, with formal washing by wash stir identical, carry out on one side and make under the state that washing and dewatering groove 9 is static to make 11 rotatings of rotating vane dish, Yi Bian circulating pump 16 is turned round and make to be stored in the washings circulation stirring rinsing that the water of the bottom of water jacket 10 circulates in the mode of falling the washings rotating vane dish 11 from nozzle 34.

Then, under the state stopped in the running of the rotation that makes rotating vane dish 11 and circulating pump 16, be stored in the mode that the water level of water of the bottom of water jacket 10 do not make water level surpass designated water level with detection and carry out make-up water.

Then, carry out on one side and make under the state that washing and dewatering groove 9 is static to make 11 rotatings of rotating vane dish, Yi Bian circulating pump 16 is turned round and make to be stored in the washings circulation stirring rinsing that the washings of the bottom of water jacket 10 are circulated to fall the mode on the washings rotating vane dish 11 from nozzle 34.Identical with when washing, because the washings in washing and dewatering groove 9 substitute on circumferencial direction and radial direction, so washings spread all over washings, and detergent ingredients is diluted.

Mean same section with embodiment example 1 same-sign, therefore description thereof is omitted.The present embodiment example is characterised in that the base shape of rotating vane dish 111 is bowl-types.In addition, do not use circulating pump in the circulation of washings, do not there is functions/drying.Front side at overhead guard 2 arranges the display floater 108 that possesses display, various pushbutton switch, with the control device 14 that is located at the cabinet bottom, is electrically connected to.At the rear portion of overhead guard 9, built-in water supply electromagnetic valve 4, washing agent, softener drop into container 128.

Bottom inside rotation at washing and dewatering groove 9 arranges rotating vane dish 111 freely.Figure 16～Figure 19 means the detailed construction of rotating vane dish 111.Figure 16 is the stereogram of rotating vane dish 111, Figure 17 is the top figure (top view) of rotating vane dish 111, Figure 18 is the cutaway view of the rotating vane dish 111 that dissects of the left and right center line VI-VI with Figure 17, and Figure 19 is the cutaway view of the rotating vane dish 111 that dissects of the VII-VII of horizontal line up and down with Figure 17.

The upper surface of rotating vane dish 111 is identical with the rotating vane dish of embodiment example 1, formed by a plurality of protrusion 111a and the 111b of paddy section that is formed between this protrusion 111a, possess two protrusion 111a that form across the pivot P of rotating vane dish 11 and be formed on two 111b of paddy section between this protrusion 111a.And from radial location r at outer circumferential side in one direction, with arc-shaped bend roughly, protrusion 111a and the 111b of paddy section observe and are roughly S word shape from top for protrusion 111a and the 111b of paddy section, left and right is asymmetric, with respect to pivot P point symmetry.

With respect in embodiment example 1, form protrusion 11a and the 11b of paddy section on the disk of general plane shape, in present embodiment example 2, be characterised in that formation protrusion 111a and the 111b of paddy section on and bowl-shape concave curved surface that outer circumferential side is high low in central authorities.

As shown in figure 18, protrusion 111a forms highly and uprises gradually towards peripheral direction from pivot.And as shown in figure 19, the 111b of paddy section is formed by bowl-shape concave curved surface, has inclined plane 111i in the outside.In the present embodiment example, for the movement of the above-below direction that increases washings, make the treble height of aspect ratio protrusion 111a of peripheral part 111j of bowl-shape concave curved surface low, but can be also equal height.The peripheral end face 111f of protrusion 111a is so that the inclined plane that the mode that topple over to central side on top tilts.For rotating vane dish 111 is fixed on the washing dehydration drive unit, bellying 111k upward, the space of guaranteeing the folding and unfolding hold-down screw are set around pivot P.Dissect in a circumferential direction shapes while launching, rotating vane dish 111 upper surfaces at the pivot from rotating vane dish 111 in radial location arbitrarily identical with the shape shown in Fig. 7 (b).But the position of the difference of height maximum of the lowest point 111b1 of the crest line 111a1 of protrusion 111a and the 111b of paddy section is the radial location that becomes the end of bowl-shape concave curved surface, to compare and reach more to the inside the outside herein, difference of height is less.

Bottom surface at the bowl-shape concave curved surface of the 111b of paddy section has to a plurality of ridge 111d of the direction bending identical with protrusion 111a.Crooked shape and protrusion 111a are roughly the same.In present embodiment example 2, as shown in figure 17, ridge 111d is configured in the position of equal angular one by one across the lowest point 111b, and is located at respect to the point-symmetric position of pivot P (amounting to everywhere).In addition, the bellying 111e that possesses a plurality of spherical crown shapes at the upper surface of rotating vane dish 111.Bellying 111e is configured to be dispersed in the part beyond zone on the top of protrusion 111a.Ridge 111d and bellying 111e have washboard effect, thereby improve cleaning force.

In addition, the upper surface at rotating vane dish 111 possesses a plurality of 111c of the through hole for water flowing and ventilation.Through hole 111c is configured to be dispersed in the part beyond zone and ridge 111d, bellying 111e on the top of protrusion 111a.

While making rotating vane dish 111 left/right rotations carry out washing/drying, the movement of washings now and embodiment example 1 are roughly the same.That is, utilize the rotation of rotating vane dish 111, washings up-down vibration on one side along the circumferential direction moves on one side on the direction of rotation of rotating vane dish 111.And, when rotating vane dish 111 is turned right, washings is easily to the medial movement of washing and dewatering groove 9, when turning left, easily to the internal perisporium side shifting.In addition, the clothing that utilizes centrifugal force to move to the outer circumferential side of rotating vane dish 111 is mentioned upward by the inclined plane 111i of bowl-shape concave curved surface.Therefore, do not need the internal perisporium at washing and dewatering groove 9 as implemented mode example 1 that lifter is set.In addition, owing to thering is the effect that utilizes bowl-shape concave curved surface that washings is mentioned upward, therefore can be less than the occasion of embodiment example 1 to the angle of inclination of peripheral direction from the pivot of protrusion 111a.

In the electric washer of present embodiment example 2, do not use circulating pump in the circulation of washings, but utilize the method for the following stated to carry out.

Possesses radial a plurality of back blade 111m at the back side of rotating vane dish 111 (lower surface).Washing and dewatering groove 9 bottoms around rotating vane dish 111 be provided for making rotating vane dish 111 around and the bottom annulus 9d of the ring-type of the gap turn narrow between the inner peripheral surface of washing and dewatering groove 9.The interior week of bottom annulus 9d is cylindric, and the bottom surface of its lower surface and washing and dewatering groove 9 is closely sealed.And, forming labyrinth type (ラ PVC リ Application ス) by peripheral part and the bottom annulus 9d of rotating vane dish 11, washings are difficult to the Clearance Flow with bottom annulus 9d at rotating vane dish 11.Form a plurality of notch on the annulus 9d of bottom, cyclic water channel cover 71, the cyclic water channel cover 81 of washings is set on this notch.Cyclic water channel cover 71,81 is when dissecing with horizontal plane, and cross sectional shape is roughly the C word shape, backside openings, but, by making closely sealed setting of inwall of the back side and washing and dewatering groove 9, form cyclic water channel 71b, 81b.Relatively set into mouth of a river 71a, 81a in the lower end of cyclic water channel 71b, 81b and the outer circumferential side of back blade 111m.

Outlet 71c is formed at the top at cyclic water channel cover 71, can load and unload ground on outlet 71c the end of a thread filter 72 is installed.The upper end of cyclic water channel cover 81 is closed, and forms in washing and dewatering groove 9 the outlet 81c in the incision-like of general horizontal direction upper shed on the top of cyclic water channel cover 81.

When making rotating vane dish 11 rotation, back blade 111m becomes centrifugal pump, and near the pressure drop bottom surface central authorities of rotating vane dish 111 sucks the washings at water jacket 10 and the interval 91 of washing and dewatering groove from the through hole 9b that is located at washing and dewatering groove 9 bottom surfaces.And the washings that utilize the centrifugal force of back blade 111m to be pushed out laterally flow into cyclic water channel 71b, 81b from water inlet 71a, 81a, and in cyclic water channel 71b, 81b stream upward.

The washings that rise at cyclic water channel 71b utilize the end of a thread filter 72 to remove the end of a thread, and enter in washing and dewatering groove 9.On the other hand, the washings that rise at cyclic water channel 81b spill with shape spray near the central authorities in washing and dewatering groove 9 from the outlet 81c of incision-like.Thus, washings are sprayed onto on washings equably, can improve cleaning efficiency.Washings in washing and dewatering groove 9 flow out to the interval 91 of water jacket 10 and washing and dewatering groove 9 by through hole 9a.

Like this, owing to using the back blade 111m of rotating vane dish 111 in the circulation of washings, therefore, when the water yield of washings is very few, can't make the fully washings circulation of amount, washings do not spread all over washings, so cleaning force descends.Therefore, with embodiment example 1, compare, need to improve the water level in washing and dewatering groove 9.Therefore, washings is subject to buoyancy from washings, and the slip of washings on rotating vane dish 111 becomes large.Therefore, for the moving of above-below direction that increases washings, guarantee cleaning force, make the angle of inclination of circumferencial direction of inclined plane 111h, 111g of protrusion 111a larger than embodiment example 1.

In present embodiment example 2, with respect to the internal diameter size of washing and dewatering groove 9, be about 480mm, the appearance and size that makes rotating vane dish 111 is about 405mm.In the rotating vane dish 111 of this size, study the result of the size of each one according to experimentally, desired size is described.Expectation from the center of the crest line 111a1 of protrusion 111a outward the tilt angle theta 13 of perimembranous be 8～15 degree, tilt angle theta 14, the θ 15 of the circumferencial direction of inclined plane 111g, the 111h of expectation protrusion 111a are 25～30 degree, and expectation is 70～80mm from the highest the difference of height to the end of the 111b of paddy section of protrusion 111a.In addition, the amount of bow θ 11 of expectation protrusion 111a and the amount of bow θ 12 of the 111b of paddy section are 20～25 degree, and crooked torsion angle 17 is 45～55 degree.

Even in present embodiment example 2, also promote washings movement along radial direction in the washing and dewatering groove, therefore can realize the cleaning force of washing raising, wash uneven minimizing.

In addition, even added the electric washer of functions/drying on the electric washer of present embodiment example 2, also can similarly apply.

(embodiment example 3)

In Fig. 3, Figure 16, the situation that is two to protrusion and paddy section is illustrated, but also is thought of as three.In this case, the rotary middle point with respect to the rotating vane dish configures symmetrically with 120 degree intervals to make protrusion and paddy section.Even like this, also obtain and embodiment example 1, effect, effect that embodiment example 2 is identical.In addition, also can increase the vibration number of the above-below direction that the rotating vane dish rotates each time.But, while when for washings slides and moves on the rotating vane dish, and angle of inclination and the embodiment example 1, the embodiment example 2 that make the lateral tilting inclined-plane of protrusion be during for identical degree, the difference of height of the lowest point of the crest line of protrusion and paddy section diminishes.Therefore, because vibration number increases, the amplitude of vibration diminishes, so cleaning force and embodiment example 1, embodiment example 2 are identical.But, because the quantity of protrusion and paddy section increases, therefore be difficult to produce the bias of the circumferencial direction of washings in the washing and dewatering groove, there is the vibration while reducing to dewater.

But, when the quantity of excessive increase protrusion and paddy section, Yi Bian be difficult to guarantee the difference of height of the lowest point of the crest line of protrusion and paddy section, Yi Bian make the angle of inclination on inclined plane of protrusion little and smooth and easy.; the angle steepening on inclined plane; washings is difficult to utilize the rotation of rotating vane dish to carry out the movement of vibrating in the upper surface slide of rotating vane dish on one side on one side on above-below direction, approaches the movement of the washings identical with the stirring vane (bobbing machine) of common electric washer.Therefore, the quantity of expectation protrusion and paddy section is 2～3.
