Rinsing maching
Technical field
The present invention relates to comprise the rinsing maching of the washing and dewatering groove that washs and dewater.
Background technology
In the past, had the rinsing maching that the washing and dewatering groove is arranged to center on the rinsing maching of vertical axis rotation or is arranged to center on horizontal rotational shaft.
Wherein, the former rinsing maching is for example well-known, can being provided with the washing and dewatering groove rotatably in the tank of water storage, on the perisporium of this washing and dewatering groove, has a plurality of dewatering holes, can have stirring body rotatably in lower inside.And this rinsing maching is provided with protuberance on the inner face of washing and dewatering groove, realizes the raising of washing (-)off properties thus.As the shape of this protuberance, be smaller hemispherical of a plurality of diameters on the inner face that is arranged on the washing and dewatering groove.In this rinsing maching,, contact with hemispheric protuberance through washings and to give mechanical force, but the effect of raising washing (-)off properties is also not really abundant in when operation washing.
About this point; In Japan's publication communique for example 2005-348943 number (patent documentation 1); A kind of rinsing maching is disclosed; Wherein: on the perisporium of washing and dewatering groove, form the protuberance of section mountain peak shape, utilize the bight of this protuberance when the washing operation, to give cleaning effective mechanical force to washings.In this rinsing maching, the first half of protuberance leans forward to the direction of rotation of washing and dewatering groove, and the Lower Half of protuberance is extended to the approximate vertical direction.Therefore; The Lower Half of the approximate vertical of protuberance is given effective mechanical force to washings when the washing operation; In addition; When dehydrating operation, be accompanied by the rotation of washing and dewatering groove, can in groove, obtain air efficiently, can realize the raising of washing (-)off properties and dewatering through the first half that leans forward of protuberance.
When the washing operation, as well-known, in tank and washing and dewatering groove, feed water, through the positive and negative rotation driving of stirring body washings is cleaned.Therefore, than following variance, it is uneven to suppress laundry so preferably strengthen the exchange up and down of washings away from the washability of the sink internal upper part of stirring body.
But in the rinsing maching that patent documentation 1 is put down in writing, protuberance forms section mountain peak shape, and its first half forms the shape that leans forward, so the spinning upside down of the washings when being inappropriate for the washing operation.That is, effective mechanical force can be given through contacting with washings in the bight of protuberance, but opposite, may hinder the exchange up and down of washings.
On the other hand, when dehydrating operation, rotate at a high speed and with the washings centrifugal dehydration through the washing and dewatering groove.About this point, in said drum-type washing machine, rotate at a high speed and with the washings centrifugal dehydration through cylinder as the washing and dewatering groove.In any rinsing maching, (promptly have nothing to do around the vertical axis rotation or around horizontal rotational shaft) with the washing and dewatering groove; Dewatering greatly influences wash effect, drying effect of back etc.; So preferably make the rotation as far as possible at a high speed of washing and dewatering groove, obtain higher dehydration rate.
But, being accompanied by the centrifugal action of washings is strengthened, washings is with on the inner peripheral surface that is urged overlapping state and is close to the washing and dewatering groove, is not easy it is peeled off to untie.Therefore, when behind this dehydrating operation, carrying out rinsing and the dry operation of carrying out afterwards when waiting, washings peeled off needs the time, so efficient is lower, has on dried washings problems such as generation fold.Therefore, the rinsing maching of Japan's publication communique 2008-79762 communique (patent documentation 2) for example is provided with the protuberance of a plurality of toroidals on the inner peripheral surface of washing and dewatering groove, and is provided with dewatering hole in its mountain valley portion.
But; In the rinsing maching that patent documentation 2 is put down in writing, be used to make the protuberance of peeling off the easy a plurality of toroidals that become to have following shortcoming: easy and current collide and make the current diffusion, hinder the discharge outside groove of water; In addition through with the contacting of washings, be easy to generate the cloth damage; Also leave and improve leeway.
Summary of the invention

Here, for the concrete shape of described geosynclinal convex portion 18 and dewatering hole 16, condition is set, be described in detail with reference to Fig. 2～Fig. 5 C.At first, Fig. 2 representes the configuration structure of geosynclinal convex portion 18 and dewatering hole 16, and Fig. 3 representes its enlarged drawing.In addition, Fig. 5 A, Fig. 5 B and Fig. 5 C represent the cutaway view that 5A-5A, 5B-5B line and 5C-5C line in Fig. 3 are cut open respectively.In addition, Fig. 4 representes the amplification stereogram of geosynclinal convex portion 18.
Geosynclinal convex portion 18 integral body form the half the abacus pearl that roughly is divided into shown in Figure 4, observe quadrangle shapes (with reference to Fig. 2, Fig. 3) such as for example forming rhombus from the footpath direction (the arrow D1 direction Fig. 4, Fig. 5 A, Fig. 5 B) of washing and dewatering groove 15.As shown in Figure 3 in detail, the profile of geosynclinal convex portion 18 for example forms from footpath direction and observes that the length L c on all limits equates and all angles are the square shape at right angle.In addition, geosynclinal convex portion 18 forms horn shape with respect to the 1st vertical section of the central axis O of washing and dewatering groove 15 (with reference to Fig. 1, i.e. direction of principal axis), forms the curve-like that does not have the bight with the 1st section quadrature along axial the 2nd section.In the present embodiment, for example the cross section of geosynclinal convex portion 18 promptly the 1st section form the triangular shape shown in Fig. 5 B (mountain peak shape), longitudinal section i.e. the 2nd section forms circular-arc shown in Fig. 5 A.In addition, the crest line 18a directed in orthogonal direction of geosynclinal convex portion 18, so the geosynclinal convex portion 18 on the Zhou Fangxiang of the size of the geosynclinal convex portion 18 on the direction of principal axis and washing and dewatering groove 15 is sized to roughly the same.Owing to have metallic luster, the geosynclinal convex portion 18 that forms above-mentioned shape presents the such outward appearance of so-called diamond when observing.
This geosynclinal convex portion 18 disposes a plurality of (for example 4) side by side on direction of principal axis, to become the mode of row, and being listed in of this geosynclinal convex portion 18 is equipped with multiple row on the Zhou Fangxiang.At this moment, geosynclinal convex portion 18 is with closeer spacing configuration, and is as shown in Figure 3, axial spacing Pa 1Spacing Pc with Zhou Fangxiang 1Be set to value (Pa about equally 1≈ Pc 1).In addition, the row of geosynclinal convex portion 18 are provided in Zhou Fangxiang and go up adjacent geosynclinal convex portion 18 and on direction of principal axis, misplace each other.Its magnitude of misalignment is set to axial spacing Pa 1Roughly half the value (Pa 1/ 2), between the row of geosynclinal convex portion 18, form jagged gap.In other words this gap is the width dimensions Lf between geosynclinal convex portion 18 adjacent on the Zhou Fangxiang in the par that does not form geosynclinal convex portion 18 34 of barrel 15b, than the short (Lf＜Lc) of the length L c on one side of geosynclinal convex portion 18.
On the other hand, dewatering hole 16 is set the centre for the row that are positioned at geosynclinal convex portion 18 at barrel 15b.Therefore, as shown in Figure 2, dewatering hole 16 forms row L along the center line of the par 34 that the zigzag shown in the single-point line is extended, and the row L of this dewatering hole 16 is positioned at the centre of the row of geosynclinal convex portion 18, on Zhou Fangxiang, is equipped with multiple row.Therefore, the spacing of the Zhou Fangxiang of dewatering hole 16 is (in Fig. 2, through Pc 2Represent its mean value) be provided with closelyer equally with geosynclinal convex portion 18.In addition, dewatering hole 16 on direction of principal axis with closeer spacing Pa 2(with reference to Fig. 3) configuration, the row L of dewatering hole 16 misplaces on direction of principal axis at dewatering hole adjacent on the Zhou Fangxiang 16 each other.Its magnitude of misalignment is set to said spacing Pa 2Roughly half the value (Pa 2/ 2).
In addition, the circumference of dewatering hole 16 such radius vector direction outside shown in Fig. 5 C is outstanding, and its protuberance is implemented deburring (burring) processing.In addition, detailed explanation is omitted, and is used to catch the filter mechanism (not shown) of collecting line suede (lint) but on barrel 15b, be provided with, so have the non-formation part that does not form geosynclinal convex portion 18 and dewatering hole 16.Therefore, geosynclinal convex portion 18 and dewatering hole 16 are formed at and on Zhou Fangxiang, clip non-3 zones that form part, and Fig. 2 enumerates in these 3 zones.That is, number, the shape of geosynclinal convex portion 18 and dewatering hole 16 are not limited to accompanying drawing, comprise their spacing Pa 1, Pc 1And Pa 2, Pc 2, can suitably change.In addition, said " roughly half the " comprises " half the ", also can the said magnitude of misalignment of geosynclinal convex portion 18 be set at spacing Pa 1Just in time half the value.Same therewith, the magnitude of misalignment of dewatering hole 16 also can be set at spacing Pa 2Just in time half the value.
Next, the effect for the rinsing maching of said structure describes.At first,, then stirring body 20 is carried out positive and negative rotation and drive, not shown washings is cleaned in the laundry in the washing stroke, the rinsing predetermined water level that as well-known, in tank 4 and washing and dewatering groove 15, feeds water in service.And, contacting and receive mechanism at the washings that moves with current in service of for example doing washing with geosynclinal convex portion 18 outstanding on inner face, this geosynclinal convex portion 18 helps the raising of clean ability.
At this moment, the geosynclinal convex portion 18 of formation cross section horn shape also acts on bigger resistance with respect to the direction flowing water flow of dislocation to the left and right.In addition, owing to be positioned at dislocation spacing Pa on direction of principal axis each other in geosynclinal convex portion 18 adjacent on the Zhou Fangxiang 1Roughly half the position, so the row of geosynclinal convex portion 18 can reliably and effectively obtain bigger mechanism with respect to the washings contact of moving with current.
Certainly, below the bigger stirring body 20 of diameter especially above stirring protuberance 21 not only generate the washing current through its rotation, and directly contact with washings and give mechanism, help the raising of washing (-)off properties.In service in this laundry, the resistance of the above-below direction (direction of principal axis) relative with washings with current that forms the circular-arc geosynclinal convex portion 18 in longitudinal section is less, so can strengthen the exchange up and down of washings, it is uneven to suppress laundry.
Next, describe for following the dry trip that carries out behind the above-mentioned washing stroke.In this dry trip, for example mainly carry out dehydrating operation in the early stage, carry out the drying operation then.That is, in dehydrating operation, with stirring body 20 washing and dewatering groove 15 being rotated at a high speed (for example, 900rpm), carries out the centrifugal dehydration of washings, moisture is removed as much as possible.At this moment, to constituting heater 26 energisings that hot blast forms unit 24, only energising does not drive pressure fan 25.This is because the effect that under a large amount of moisture state after the washing, heats with respect to washings is less, so suppress thermal waste for no reason.
Got access to extraneous air in the housing 28 along path flow here, towards the dotted arrow direction shown in Fig. 1.That is, supply with in tank 4 and washing and dewatering groove 15 from giving tracheae 30, contact with washings and help desiccation as the cold wind of extraneous air, then through peristome 17, dewatering hole 16 to tank 4 side shiftings.At this moment; Tank 4 is maintained roughly air-tight state by the groove lid 9 that inner cap 9a is in closed condition, and is accompanied by the rotation of washing and dewatering groove 15, becomes vacuum between the tank 4 of washing and dewatering groove 15 and its periphery; Be accompanied by the effect that sucks air from the open upper end of this washing and dewatering groove 15; Cold wind moves to tank 4 through dewatering hole 16 grades rapidly, arrives in the vent passage 10 from the connected entrance 12 of tank 4 bottoms, and rises and discharge outside groove from the filter 14 of ventilation guide part 13.Afterwards, outside main body 1, discharge, perhaps a part is discharged outside main body 1 from the lower ending opening of outer container 2 from the notch 23a of the enclosing cover 23 of closed condition.
In this dehydrating operation, the inclined plane from the water of washings centrifugal dehydration along geosynclinal convex portion 18 accumulates in par 34, emits effectively from dewatering hole 16.That is, geosynclinal convex portion 18 with the width dimensions Lf of par 34 than the short mode of the length L c on one side of geosynclinal convex portion 18 with closeer spacing configuration, concentrate so the water capacity of centrifugal dehydration is prone in the par 34.In addition, the row L of dewatering hole 16 is located at Zhou Fangxiang and goes up adjacent dewatering hole 16 dislocation spacing Pa on direction of principal axis each other 2Roughly half the position, be not configured in par 34, so can be efficiently from dewatering hole 16 drainings (dehydration) with omitting.At this moment, the water of emitting from dewatering hole 16 has ground, dead angle evenly not to be spread across the inner face side of tank 4, so improve with clean effect to tank 4 inner faces.
And in washing and dewatering groove 15, washings is in accepts centrifugal action and to the state of barrel 15b side shifting, therefore carries out effective dehydration to being the washings that central portion becomes the Deep-fried doughnut shape in cavity.About this point, on barrel 15b, be provided with geosynclinal convex portion 18 with closeer spacing, so suppressed washings with respect to being close to of barrel 15b, can between washings and barrel 15b (particularly the par 34), produce the gap.Therefore, when the air that will in washing and dewatering groove 15, supply with through dewatering hole 16 was emitted, washings became good with contacting of cold wind.In addition, 34 do not dispose dewatering hole 16 with omitting in the par, so it is uneven to suppress dehydration, whole dewatering efficiency improves.
So; Carried out the scheduled time at dehydrating operation, in the time of will fully removing from the moisture of washings; Heater 26 energising heating and with the extraneous air hot blastization; (for example, 400rpm), beginning is moved by the formal drying that so-called warm-air supply carries out simultaneously washing and dewatering groove 15 to be controlled to be low speed rotation.Hot blast distinguished and admirable of this moment flowed in the actual identical path with above-mentioned dehydrating operation the time, carries out and the contacting of washings, and is accompanied by heating, more effectively captures the desiccation of moisture.Too in service in this drying; Washings is in accepts centrifugal action and to the state of barrel 15b side shifting; Same with the cold wind of above-mentioned dehydrating operation, said hot blast fully helps to carry out desiccation, is sidelong out to tank 4 then; Discharge outside groove through vent passage 10, outside main body 1, discharge then.In addition; In comprising the dry trip of above-mentioned dehydrating operation; In order to improve drying efficiency, for example also can adopt with washing and dewatering groove 15 temporarily stop at any time, only rotation drives stirring body 20 and the method that will untie to the washings of barrel 15b side shifting in this period.At this moment, though in service in drying be low speed rotation, washings is accepted centrifugal action and to all side shiftings, still is configured to the Deep-fried doughnut shape and under above-mentioned form, promotes desiccation.
Then; When the scheduled time has been carried out in the drying of being undertaken by this hot blast operation, the completion operation scheduled time that heater 26 outages and carrying out are undertaken by cold wind (extraneous air), washings is made as cooled completion status; Finish a series of dry trip, finish all strokes.
Then, when the washings of washing and dewatering groove 15 is taken out, as stated because geosynclinal convex portion 18, suppressed washings with respect to being close to of barrel 15b, also can easily peel off even washings is close on the barrel 15b.In addition, it is circular-arc that geosynclinal convex portion 18 forms the longitudinal section, and the resistance of above-below direction (direction of principal axis) is less, so can carry out the taking-up input of washings smoothly.In addition; In the above-described embodiments; Running for carrying out washing stroke and dry trip automatically continuously is illustrated, even but set the running of only carrying out dry trip, obtain and the same effect of above-mentioned drying operation with also can having no obstacle; When in the middle of carrying out in washing stroke, between laundry and rinsing, carrying out, dewatering certainly, also can play the effect same with above-mentioned dehydrating operation.
According to the above embodiments, can access following effect.
A plurality of geosynclinal convex portion 18 is set on the inner face of the barrel 15b of washing and dewatering groove 15; The 1st section that this geosynclinal convex portion 18 is vertical with respect to the direction of principal axis of washing and dewatering groove 15 forms horn shape, will form the curve-like that does not have the bight with the 2nd section of the 1st section quadrature.Thus, the current in 18 pairs of washing and dewatering grooves of geosynclinal convex portion 15, washings are to the bigger resistance of all directive effects, so can strengthen the ability of cleaning to the effective mechanical force of washings transmission through the bight of geosynclinal convex portion 18.Relative therewith, the 2nd section forms the curve-like that does not have the bight, and the resistance of the above-below direction of geosynclinal convex portion 18 (direction of principal axis) becomes minimum, so can carry out the taking-up input of washings smoothly.And when the washing operation, can carry out the exchange up and down of washings smoothly.Thus, can provide and suppressed uneven, the total washing (-)off properties higher rinsing maching of laundry.In addition, according to said structure, the washings in the time of can suppressing dehydrating operation, dry operation with respect to being close to of barrel 15b, can expect the raising of dewatering and drying property.Promptly; When dehydration, dry operation; Washings is in the state to barrel 15b side shifting, but through geosynclinal convex portion 18, washings is difficult to be close on the barrel 15b; Especially between washings and par 34, be easy to generate the gap, so can make washings become good with contacting of air (cold wind and hot blast).
Such effect forms and also can bring into play fully when circular-arc for geosynclinal convex portion 18 the 1st section being formed triangular shape, the 2nd section.That is, can its shape be made as under the situation of fairly simple structure, reduce the resistance that axial resistance increases Zhou Fangxiang simultaneously.
Side by side be equipped with a plurality of on direction of principal axis, to become the mode of row geosynclinal convex portion 18; Being listed in of this geosynclinal convex portion 18 is equipped with multiple row on the Zhou Fangxiang; So can not omit ground configured slot protuberance 18 on the whole at the inner face of barrel 15b, can improve above-mentioned effect on the whole at barrel 15b.In addition, the row with geosynclinal convex portion 18 are arranged in the dislocation spacing Pa on direction of principal axis each other of the upward adjacent geosynclinal convex portion 18 of Zhou Fangxiang 1Roughly half the.Thus, effective configuration structure irrelevant with the amount (upper-lower position) of the water yield (water level), washings, that washings is contacted with geosynclinal convex portion 18 reliably can be made as, clean ability can be further improved.
With closeer spacing configured slot protuberance 18, between geosynclinal convex portion 18, be provided with dewatering hole 16 with the mode in the gap that between the row of geosynclinal convex portion 18, is formed with sawtooth (zigzag) shape on the barrel 15b.Thus, when dehydrating operation (dry operation), can more effectively suppress washings is close on the barrel 15b.In addition, the water capacity of centrifugal dehydration is prone to concentrate on par 34 along the inclined plane of geosynclinal convex portion 18, can the water that should concentrate be emitted from dewatering hole 16 effectively, can further improve dewatering.And then, between the par 34 of washings and barrel 15b, more be easy to generate the gap, so can make air better, can further improve dewatering and drying property with contacting of washings.
At this moment; With observe from the footpath direction gap form between four limit shapes and the adjacent geosynclinal convex portion 18 than the short mode of the length L c on one side of geosynclinal convex portion with closeer spacing configured slot protuberance 18, can improve washing (-)off properties thus significantly and from wait performance of moisture being removed each step that goes to drying through dehydration.
In addition, on barrel 15b, between geosynclinal convex portion 18; Be arranged on a plurality of dewatering holes 16 that become row L on the direction of principal axis; The row L of this dewatering hole 16 is equipped with multiple row on Zhou Fangxiang, thus ground configuration dewatering hole 16 can on par 34, do not omitted, can be efficiently from dewatering hole 16 drainings.And, the row L of dewatering hole 16 is arranged in Zhou Fangxiang goes up adjacent dewatering hole 16 dislocation spacing Pa on direction of principal axis each other 2Roughly half the, so can be more efficiently from dewatering hole 16 drainings.In addition; Thus; Dewatering hole 16 spreads all over the roughly evenly configuration integrally of barrel 15b; So when dehydrating operation and dry operation, the roughly complete cycle ground that can spread all over barrel 15b forms does not have uneven air flow, can suppress the dehydration inequality, uneven drying of washings as possible and expect good completion effect.And then the water of when dehydrating operation, emitting from dewatering hole 16 has dead angle ground evenly not to be spread across the inner face side of tank 4, so can improve and clean effect to tank 4 inner faces, need not take a lot of trouble just can tank 4 be kept clean.
The size of the size of the geosynclinal convex portion 18 on the direction of principal axis of washing and dewatering groove 15 and the geosynclinal convex portion 18 on the Zhou Fangxiang is set at roughly the same.Thus, that kind uniformly-spaced disposes a plurality of geosynclinal convex portions 18 and raising appearance design property as stated.That is, barrel 15b is made up of the corrosion resistant plate with metallic luster, and geosynclinal convex portion 18 forms through punch process, so can utilize its metallic luster to improve outward appearance.And the geosynclinal convex portion 18 that forms above-mentioned mode (shape and configuration) presents the such outward appearance of so-called diamond of proper alignment, so can be with being made as beautiful brand-new outward appearance in the washing and dewatering groove 15 along with separately reflection of light (perhaps metallic luster).In addition; Constitute barrel 15b by a corrosion resistant plate; Can not use other member ground simply geosynclinal convex portion 18 to be shaped, and can implement the deburring processing of dewatering hole 16, so can reduce manufacturing cost as possible through the operation identical with said punch process through punch process.

Here, especially with reference to Figure 11～Figure 13, the concrete structure for the said geosynclinal convex portion 63 on the barrel 60a cylindraceous that is formed on cylinder 60 comprises with dewatering hole 61 relevant relational structures describing.
At first, for the shape of geosynclinal convex portion 63, describe based on Figure 11, Figure 12 A and Figure 12 B.This Figure 11 is the amplification front elevation of the major part of observing from the inboard of cylinder 60, and Figure 12 A is that the 12A-12A line in Figure 11 cuts off and the cutaway view of expression, and Figure 12 B is that the 12B-12B line in Figure 11 cuts off and the cutaway view of expression.In addition, the inboard that the open side that Figure 11 diagram will have balance ring 65 is regarded as top, will have an end plate 60b is regarded as the major part of the cylinder 60 of bottom, and the direction of rotation r that therefore dewaters representes illustrated horizontal direction.
Shown in Figure 11, Figure 12 A and Figure 12 B, geosynclinal convex portion 63 forms the outer shape of the elliptical shape (being similar to rugby ball shape on the imagination) outstanding to the inside, that integral body is flat, front end is thinner, also forms symmetric shape up and down.For example illustrated profile part up and down forms the circular shape of big (radius R 1 of only representing a side among Figure 11) of radius respectively; To be made as much littler (among Figure 11 with the both ends of its quadrature than above-mentioned radius R 1; Through radius R 2 expression) circular shape; These two profile parts are gently connected on tangential direction, such as stated thus, the outer shape of the elliptical shape that formation integral body is flat, front end is thinner.Symbol z shown in Figure 11 representes the center line through the diagram vertical direction of the central point c of geosynclinal convex portion 63.
And, the central portion in geosynclinal convex portion 63, with the mode of center line z quadrature, promptly be formed with at more rectangular upwardly extending crest line 63a with mode with dehydration direction of rotation r level.But crest line 63a has the shape of circularity for its top, along with being that left and right end portions is extended to it than length direction, fades away.That is, the opposite face (illustrated upper face side and following side) that clips the crest line 63a of central authorities all forms tabular surface (h), descends to tilting to extend to bigger radius R 1 to delineating circular-arc profile part (with reference to Figure 12 A).
Relative therewith; The left and right end portions of crest line 63a that comprises the scope of being surrounded by the circular shape of radius less (radius R 2) is shown in Figure 12 B; Present suitable curved surface shape (k) with mild circular-arc the linking to each other of crest line 63a; The border of above-mentioned tabular surface (h) and curved surface shape (k) (for the ease of explanation, expression by a dotted line in Figure 11) is not to form circular-arc with the mode of corner angle continuously.But described crest line 63a is up to the surf zone of the curved surface shape (k) of its left and right end portions, forms not present that step ground gently becomes the surface of said geosynclinal convex portion 63 at last and the structure that disappears.Thus, the both ends than length direction that form this geosynclinal convex portion 63 form level and smooth fairshaped form.
Next, based on Figure 11, Figure 13 the concrete structure of said dewatering hole 61 is described especially.
Figure 13 is the figure that the part of the barrel 60a of cylinder 60 is launched to represent, is expressed as the allocation plan with front openings portion, and wherein, illustrated upper side is the input port of washings.Therefore, on this peristome, engaging via through hole 86 screw threads has said balance ring 65, the scope (bottom) that the position shown in the double dot dash line L3 is represented to be installed among the figure balance ring 65 is shared.On the other hand, the double dot dash line L4 among the figure shown in the bottom representes the inner face position with the said end plate 60b of the backside openings of the inboard of barrel 60a sealing, has the through hole 87 that the bolt of fixing this end plate 60b is used.The effective zone of (between double dot dash line L3, the L4) is formed with dewatering hole 61 between this balance ring 65 and end plate 60b.Certainly, the geosynclinal convex portion 63 of described shape also is configured in same area, but narrates in addition for its configuration structure.
At first, shown in figure 13 as the configuration structure of the integral body of dewatering hole 61, be the structure of comparing with front openings side (balance ring 65 sides), the inboard (end plate 60b side) of cylinder 60 disposes morely.This be because, in this 2nd embodiment, near the barrel 60a of (be equivalent to double dot dash line L3 under position) open side; Be provided with subregion with dewatering hole 61; Relative therewith, near the inboard is set to dewatering hole 61 end plate 60b always, its result; In the effective zone of barrel 60a, dewatering hole 61 is more in the configuration number of area inside.Therefore, also can replace this structure, with the disposition interval of the dewatering hole that is arranged on open side 61 be provided with " dredging ", be provided with this disposition interval of inboard than " close ", but above-mentioned the 2nd embodiment manufactures and designs easily, favourable in this respect.
And then a plurality of dewatering holes 61 and geosynclinal convex portion 63 be with respect to the dehydration direction of rotation r of cylinder 60, in the direction of retreating to the inside from the open side arrangement that tilts.Promptly; The arrangement of dewatering hole 61 and geosynclinal convex portion 63 be set at the layout line x of direction of rotation r level of dewatering on; On the other hand, the arrangement of illustrated above-below direction is set at respect to the layout line x of level on the layout line y of dehydration direction of rotation r tilt predetermined angular β.In addition, geosynclinal convex portion 63 forms up and down central point c and is set in layout line x, y last (simultaneously with reference to Figure 11) respectively.
In addition; If narrate with the concrete configuration relation of dewatering hole 61 for geosynclinal convex portion 63 based on Figure 11, Figure 13 especially; With respect to the for example geosynclinal convex portion 63 on the layout line x of direction that is configured in the direction of rotation r level of dewatering; Be equipped with dewatering hole 61 in the position that separates of direction (in the drawings, being above-below direction) to the left and right by this geosynclinal convex portion 63.Specifically; With the dewatering hole 61 in the place ahead of the dehydration direction of rotation r side that is positioned at geosynclinal convex portion 63 is that direction is (in the drawings to the left and right for starting point; Be above-below direction) separately, be provided with a plurality of dewatering holes 61 with the ordered state that tilts, the layout line of inclination is at this moment represented through the symbol of w1, v1 among the figure.
Certainly, the configuration structure of the separated dewatering hole 61 relative with other geosynclinal convex portion 63 also forms form same as described above.In addition, at the rear side (with the opposite side of dehydration direction of rotation r) of a geosynclinal convex portion 63, it is last that dewatering hole 61 also is configured the layout line w2, the v2 that are set in symmetric position.So; Shown in figure 13; Through will on barrel 60a perisporium, launching by the structure that a plurality of dewatering holes 61 constitute, the actual all dewatering holes 61 that form cylinder 60, wherein said a plurality of dewatering holes are along each the layout line w1 that surrounds a geosynclinal convex portion 63, w2, v1, v2 configuration.
Next, the effect for the drum-type washing machine of said structure describes.
As everyone knows,, set desirable running, bring into operation through the operation initiating key through guidance panel 53 when laundry proceeds to drying.At this moment, control device 84 drive motors 67, the rotating speed of control and its cylinder that directly links 60 automatically performs laundry, middle dehydration, rinsing, final dewatering and dry trip.
Below, each stroke is summarized, in the laundry stroke, after in tank 58, supplying with the predetermined washing water yield, drive motor 67, head roll 60 makes the positive and negative rotation of its low speed.In this laundry stroke, carry out laundry operation scheduled time of being undertaken by the effect of washing of so-called mallet, wherein should laundry in service, through block 62 washings that is soaked with washings that contains in the cylinder 60 is shaken then successively and falls.Next, when in the middle of beginning, dewatering, cylinder 60 is rotated at a high speed to a direction, carry out the dehydration of washings thus through centrifugal action, water is sidelong out to tank 58 from dewatering hole 61, draining outside machine.In this centre dehydration, extract the detergent ingredients that contains in a large number in advance out, efficiently to carry out ensuing rinsing.This rinsing is same with the laundry stroke, carries out through the positive and negative rotation of cylinder 60, promotes rinse action.
Then, arrive the final dewatering stroke, cylinder 60 is rotated at a high speed to a direction, carry out centrifugal dehydration.At this moment, washings is in the stronger centrifugal action of acceptance and is close to the state on the inner peripheral surface of cylinder 60, so if forward dry trip like this to, then drying efficiency is lower, can produces fold in addition and can not obtain good drying regime.And the inner peripheral surface that in the present embodiment disclosed geosynclinal convex portion 63 among Figure 11, Figure 13 etc. is formed on cylinder 60 is on the barrel 60a, remains the state of peeling off easily so can relax the fitting tightly property of washings.In addition, its detailed Action Specification is narrated in the back, and also can carry out following effective control as other control method this moment: before end of run, make the positive and negative rotation of cylinder 60 low speed, relax the state of being close to of washings, make and peel off from wall easily.
Next, arrive dry trip, drive controlling cylinder 60 makes the positive and negative rotation of its low speed, drying unit work simultaneously, and dry wind is supplied with in circulation in cylinder 60, promotes the drying of washings.That is, drive the compressor 80 of circulating fan device 77 and heat pump mechanism 79.Thus, utilize dry wind that the heat exchange effect heating of heat pump unit 72 generates in direction of arrow cocycle shown in Figure 9, from giving tracheae 76 supply in the cylinder 60 of tank 58 and rotation.
Dry wind contacts with washings in cylinder 60, promotes to capture the desiccation of moisture, discharges through the blast pipe 75 in the place ahead, arrives heat pump unit 72 once more.Here, the dry wind that contains moisture in a large number is by evaporimeter 82 coolings, airborne hydrogenesis and dehumidifying.This dried air sends to condenser 81 sides, and here the cold-producing medium with HTHP carries out heat exchange, and air is heated and becomes new dry wind, and once more via peripheral passage 71 circulations, sequentially feeding in cylinder 60 promotes desiccation.
In addition, when drying operation beginning,, be in the state of untiing, then clearly can access the effective dry effect of being undertaken by dry wind that does not have inequality if peeled off from the inner peripheral surface of cylinder 60 by the washings of final dewatering.But; According to present embodiment; The phenomenon of being close at the dehydration washings finish time obtains relaxing; And the positive and negative rotation of the cylinder 60 through dry operation, become the state of untiing rapidly, effectively applied flexibly in there not being uneven effective dry effect from the dry wind that begins most to blow to washings of drying operation.At this moment, as stated, before dehydrating operation finishes, make the positive and negative rotation of cylinder 60 low speed, relax the state of being close to of washings, make and peel off from wall easily, when carrying out such control, need not explanation, can more effectively washings be untied, promote desiccation.
Here, the concrete function for geosynclinal convex portion 63 shown in the present embodiment and dewatering hole 61 is elaborated with reference to Figure 11, Figure 13 below especially.At first; If the situation to above-mentioned final dewatering stroke describes, and is shown in figure 13, the outstanding a plurality of geosynclinal convex portion 63 that is provided with on the inner peripheral surface of barrel 60a; So can suppress washings closely contacts; Centrifugal action becomes the state of peeling off after disappearing, and at least easily becomes the state of peeling off easily.Especially, shown in figure 13 in the present embodiment, dispose dewatering hole 61 with the mode of surrounding each geosynclinal convex portion 63, promptly dewatering hole 61 is configured to a structural units with the row along layout line w1, w2, v1, v2, and this structural units is expanded to whole barrel 60a.Like this; Tabular surface with dewatering hole 61 does not have to form continuously the surf zone of broad; Therefore from dewatering hole 61 the so-called adsorbing strong centrifugal action that water is centrifugal when emitting can not acted on the scope of the broad of washings, this point suppress to become washings be close on the barrel 60a inner face fit tightly on the state effective.
As stated, can be made as the state of easily washings being peeled off from the configuration structure that comprises geosynclinal convex portion 63 and dewatering hole 61, moreover, these geosynclinal convex portions 63 and dewatering hole 61 also work for dewatering, laundry performance effectively.For example, move to the inner peripheral surface of cylinder 60, be sidelong out to tank 58 from dewatering hole 61 at any time from the water of washings dehydration.Therefore, thought originally that dewatering hole 61 was many more, dewatering (dehydration rate) is good more, but relative therewith, and shown in present embodiment, when a plurality of geosynclinal convex portion 63 was set, the scope that dewatering hole 61 is set correspondingly narrowed down.
But; In the present embodiment; The outer shape of geosynclinal convex portion 63 is made as the thinner flat ellipse of front end, and the direction of rotation r side of promptly dewatering in the place ahead of a geosynclinal convex portion 63, is configured in the layout line w1, the v1 that launch to the mode of dividing right and left of this geosynclinal convex portion 63 dewatering hole 61 last; So this geosynclinal convex portion 63 itself is that the crest line 63a at top works effectively with being positioned at its central portion, with water direction spaced manner effect to the left and right.At this moment, the opposite face that clips crest line 63a is tabular surface (h), so can not become the resistance of separated current, it is flowed smoothly.And; For this quilt water of separating of direction to the left and right; Last owing to dewatering hole 61 being configured in formation with each layout line w1, the v1 at the angle of inclination of this current same tendency; So these current are discharged from this dewatering hole 61 effectively, therefore can not cause the decline of dewatering, can also expect dewatering is improved.
In addition, at this moment, the end formation of the geosynclinal convex portion 63 that contacts with the water of the inner face that arrives barrel 60a easily is streamlined by curved surface shape (k) formation that does not have crest line 63a, so resistance is less, can not make the water diffusion, can keep level and smooth current.Certainly, relax the situation that fits tightly that washings is close to, become smoothly so arrive the current of barrel 60a inner face by geosynclinal convex portion 63, good from the discharge of dewatering hole 61 outside groove, can expect efficient dewatering preferably.
Relative therewith, in the dry trip that and then the final dewatering stroke carries out, as stated, make the positive and negative rotation of cylinder 60 low speed.Therefore, geosynclinal convex portion 63 is that left and right end portions contacts with washings through it than length direction.Particularly; Moving initial contact action useful effect peels off rapidly in the washings of the inner face side that will cling to barrel 60a; Washings with being in the state of being stripped from promotes stirring action; The desiccation that does not have inequality of being undertaken can be accessed, and the higher drying effect of efficient can be accessed by dry wind.And; As stated, the left and right end portions of geosynclinal convex portion 63 is shown in figure 11 to be the outer shape of radius less (radius R 2), and crest line 63a disappears in left and right end portions; Become the surface of said geosynclinal convex portion 63 with curved surface shape (k); The end forms streamlined, so can not bring violent collision to washings, can not produce the cloth damage that is caused by contact.
But such washings contacts in laundry, rinsing execution repeatedly in service with geosynclinal convex portion 63, but owing to top said identical, can effectively suppress the cloth damage.And; Basically the CONTACT WITH FRICTION of washings and geosynclinal convex portion 63 raising of performance of can expecting to do washing, but during the mallet in drum-type washing machine washes, washings is shaken the highest position on the top of cylinder 60 through block 62; Make its whereabouts then, effective on raising laundry performance.
Yet; According to present embodiment, geosynclinal convex portion 63 is outstanding to be arranged on the barrel 60a inner face between each block 62, so also as the effective friction piece that has shaken washings and its effect; Therefore can assist shaking to work, help to wash the raising of the laundry performance of generation by mallet.And; Shown in figure 13, for geosynclinal convex portion 63, compare with open side with balance ring 65; Inboard with end plate 60b disposes morely; So in the increase that contacts of in service and washings of laundry, the raising on the performance of can expecting further to do washing, in dehydrating operation, moving originally washings in addition, to be positioned at the situation of inboard of inclination of cylinder 602 more; Therefore can give full play to the said effect of peeling off that produces by more geosynclinal convex portion 63, and can apply flexibly more dewatering hole 61 and water is discharged outside groove effectively.
According to above-mentioned the 2nd embodiment, has following effect.
The washings that when dehydrating operation, receives centrifugal force is across between each geosynclinal convex portion 63, can alleviate to the fitting tightly the position, fit tightly degree of the inner face of barrel 60a, thereby can be made as the state of peeling off easily.Therefore, for example when next carrying out rinsing, washings is untied rapidly, can efficiently carry out rinsing, and in addition in that washings is taken out when dry, it is easy that it takes out operation, and can expect to have suppressed the drying effect of fold.Perhaps, automatically perform the rinsing maching of dry trip, can access by what geosynclinal convex portion 63 produced and peeling off effect and form the state that washings is untied rapidly, can expect efficient and do not have uneven drying, the good desiccation of completion status for then dehydrating operation.
In addition, the left and right end portions than length direction of each geosynclinal convex portion 63 forms the thinner flat elliptical shape of front end, so diminish with the exposure level of washings, can alleviate the cloth damage.In left and right end portions, form curved surface shape (k) especially with crest line 63a, form so-called streamlined, so can relax and the contacting of washings.At this moment, be not limited only to dehydrating operation, also can expect same effect in the long-time laundry operation of using, rinsing operation and dry operation.And, as stated, can prevent being close to of washings, cloth damage, the setting that can further improve the rotating speed of cylinder 60 thus.Its result can access higher dehydration rate, can expect the raising of drying property, perhaps has the advantage of the free degree expansion of setting Spin Control.
And then, in geosynclinal convex portion 63, be formed with than the crest line 63a of length direction, so the disagglutinating action of the water that when dehydrating operation, is produced by this geosynclinal convex portion 63 can carry out well with dehydration direction of rotation r level.Through this disagglutinating action, can the current with the tendency concentrated be discharged outside groove from the dewatering hole 61 that is arranged between each geosynclinal convex portion 63 effectively, can expect the raising of dewatering.Especially; In above-mentioned the 2nd embodiment, the left and right end portions of geosynclinal convex portion 63 formed the circular-arc outer shape of radius less (radius R 2); Form the structure that crest line 63a fades away, evens up with curved surface shape (k) above it; So the disagglutinating action of the direction to the left and right of the water that is produced by this geosynclinal convex portion 63 can carry out well; And dewatering hole 61 is configured in formation to be separated on each the layout line w1, v1 direction at the angle of inclination of direction, so more promptly promoted the discharge effect from this dewatering hole 61 along this.
In addition, can know,, dispose more geosynclinal convex portion 63 and dewatering hole 61 in the inboard with respect to the open side as the washings input port of cylinder 60 through Figure 13.Thus, in service in laundry, it is more that washings is positioned at the tendency of inboard of the cylinder 60 that descends, thus can expect based on the raising of the laundry performance that contacts and shaken effect of the more geosynclinal convex portion 63 of inboard.On the other hand, at dehydrating operation originally, with respect to being positioned at inboard washings; More geosynclinal convex portion 63 effectively suppresses being close to of washings; And can effectively apply flexibly a plurality of dewatering holes 61 and promote dehydration, and at dehydrating operation originally, more from the dehydrating amount of washings; Also can successfully manage this situation, can expect to promote the various effects such as discharge effect of water.In addition; In above-mentioned the 2nd embodiment, in the effective zone of barrel 60a, setting does not form the zone of geosynclinal convex portion 63 and dewatering hole 61 near open side; Make thus and compare with the inboard; The configured number of geosynclinal convex portion 63 and dewatering hole 61 all tails off, but is not limited to this structure, so long as the configured number of open side is less, inboard more configuration structure gets final product.
