Description
The present invention relates to a kind of cylinder that is used for the carrying out washing treatment machine, its intermediate roll can be rotated to support within the casing of carrying out washing treatment machine and has at least one base plate and a shell, they each all form by thin plate at least in part and individually or the two all be provided with a kind of arcuate configuration of pointing to cylinder inside.
By a kind of such cylinder of WO 98/20195 cicada.Wherein this arcuate configuration makes by many hexagons that are arranged side by side that at least almost nestle up and constitutes; Therefore it is commonly referred to as the honeycomb fashion cylinder.There is spout hole hexagonal edge at its intersecting point, and the diameter that these holes should reach according to WO98/20195 only is 2 millimeters and needs funnel-shaped structure anything but, even so that also clothing is had protection when centrifugal dehydration.Correspondingly these edges must have 1.5 to 2.5 times aperture, i.e. width between 3 and 5 millimeters.
The manufacturing that is used for a kind of sheet metal of outer cover of laundry wheel has certain difficulty, and this also also is mentioned in WO98/20195.Although the centering between the arcuate configuration that is provided with in the pattern in hole and following manufacture process spends many time to still have problem that is to say, so the width of edge considers that the reason of tolerance must determine more richly.But this causes reducing of drainability again, because clothing is just drawn in the loose relatively edge when centrifugal dehydration always.It has just stopped that the alkali lye that enters in the shell position flows out to spout hole there certainly so.
Show in addition, also can extend through these small-sized spout holes to washing clothes in high centrifugation accelerates.So just two shortcomings have been mutually combined; Even can not avoid laundry damage because little hole is arranged; The hole that these are little but alkali lye when having reduced centrifugal dehydration are significantly discharged.
Make hexagonal arching upward owing to following reason is problematic in this external deep-draw processes method: rotation angle position must deep-draw on a longer distance segment than bottom line position.Therefore just produce uneven crystal structure at thin plate deep-draw position, this has nothing in common with each other material hardness.Exactly will be from going out spout hole here, and material becomes harder at this rotation angle position place, so original just thinner drift will be than also bearing bigger load when a kind of traditional roller cover of the structure that do not arch upward.
Task of the present invention provides a kind of cylinder that starts described kind, arcuate configuration has the mutual element that is being close in this cylinder, but still can enough positions be arranged to spout hole, so that make these holes for the alkali lye discharging of abundance, also have enough big diameter.The manufacturing of arcuate configuration is that itself or its effect to other setting all are out of question in addition.The better rigidity that can reach by arcuate configuration should keep at least or should improve better.
According to following the solving of this task of the present invention: arcuate configuration is made up of the projection of pointing to cylinder inside, and the edge of projection be circle or ellipse or avette substantially.Therefore projection that can be designed to arch upward, that be similar to ball-and-socket, these projectioies around it just in time with adjacent protruding tangent separately.Therefore stopped that clothing prevents on its bottom that is drilled into the edge.Deep-draw operation when making arcuate configuration is uniformly, and material keeps even matter.Those roundings owing to projection form more large-area, as to be similar to polygonal position edge automatically provides more position for bigger spout hole.Therefore the manufacturing of this arcuate configuration is than used much simple in the background technology, because needn't observe so little tolerance with respect to Manufactured hole during to the center at the structure that arches upward that makes laying.
In a kind of favourable improvement project of the present invention, these projection arrangements are on the intersection point of the polygonal axis pattern of a rule.The regular arrangement of projection also has following advantage except aesthetic value: the layout of axis pattern and the layout of hole pattern are harmonious, and this simplifies manufacturing greatly.
If the axis pattern has many equilateral triangles that adjoin each other on shell surface, be a kind of particularly advantageous version of the present invention so.That is to say this moment on the one hand can make the simplification of processing and be not possible polygonal of a kind of minimum of the edge between the projection of adjacency, also be that leg-of-mutton area is consistent herein.
A kind of improvement project of the present invention is suitable for widespread usage by structure of the present invention, and in this scheme, the center line of axis pattern is followed the shape of the outer seamed edge of shell or base plate, that is to say that they for example are straight or circular.This structure that is to say the plate-like base plate that can be applied to laundry wheel best so, and needn't form the too big area that does not have projection.
A kind of improvement project of the present invention is particularly suitable for the laundry wheel of washing machine, is used to spout hole that washing alkali liquid is flow through having arranged on the case surface in this scheme on the crosspoint in leg-of-mutton bisector between the projection.Therefore spout hole the layout here has a kind of special advantage, in case because when centrifugal dehydration, enter in this position of drum shell liquid it arrived the inner surface of drum shell, that just continues to move to the crosspoint direction from the position that these projectioies are close to mutually, and this is because the concave station between projection stretches towards the crosspoint direction; Liquid also just can not rest on the narrowest position, but works the more large tracts of land of shifting to the position, crosspoint by the there.
In the preferred design of another kind of the present invention, spout hole is arranged between the projection and is in approximate at least the work in the circular position in the crosspoint of bisector, and their circumferential rounded has formed protruding segment section circumference inwards.Thereby selected structure has improved the rigidity of shell surface.
If it is too dangerous that the locational shallow bore hole in the crosspoint of mentioning in front still turns out to be for washing clothes, according to the particularly advantageous improvement project of another kind of the present invention enough positions are arranged for this reason preferably herein so, make spout hole be arranged in leaving in the cylinder axis plane farthest from the outside funnel-shaped structure that is provided with of cylinder.Position on the crosspoint that is to say sufficiently big, even can also arrange a funnel-shaped structure, makes spout hole outside the plane of drum shell is guided into by this structure, can reach these holes by the clothing of pressing to drum shell at least according to the present invention there.
The minimum spacing of projection should be obtained according to experience, and ratio best and its diameter roughly reaches 1/8 to 1/25.Confirmed already that the value that is well suited for was about 1/10.
The ratio of this protruding height and its diameter should reach about 1/5 to 1/20 in addition.Confirmed already that the value that is well suited for was approximately 1/12.
Particularly advantageously when on the cylinder base plate, arranging bulge-structure be according to improvement project of the present invention, it is concentric that concentric line is arranged to the central point of base plate, and this be arranged in axis pattern on the concentric line have a kind of according to the shortening of the periphery of concentric line separately towards centre of the drum's point and the sideline of shortening.Therefore can form a kind of projection of homogeneous texture on base plate, it is again favourable for the congruence and the hole pattern of bulge-structure.
Correspondingly preferably, according to the favourable improvement project of another kind of the present invention, the words that the diameter of projection and/or the spacing between them reduce according to the shortening of the periphery of corresponding concentric line.The structure of base plate is except also having following advantage the congruence between the bulge-structure and hole pattern so: the structural elements on base plate of many different sizes have also exactly formed each resonator of so many different audio frequencies, though they have widened resonance spectrum very doughtily, greatly reduced its amplitude for this reason.
If cylinder is provided with the follower on the inner surface that is contained in drum shell, the surface according to another favourable this follower of design of the present invention equally also can be provided with a kind of arcuate configuration of being made up of projection so.This can be favourable for washing clothes by the processing that washing procedure carries out machinery.
Below the embodiment shown in reference to the accompanying drawings narrates the present invention.Be depicted as:
Fig. 1: a kind of stereogram of laundry wheel, this cylinder is being provided with according to bulge-structure of the present invention on its drum shell He on the base plate;
Fig. 2: a kind of expansion intercepting partial graph with a kind of drum shell by bulge-structure form of the present invention of being provided with of shallow spout hole;
Fig. 3: the enlarged cross sectional view of a kind of arch projection of III-III hatching in Fig. 2;
Fig. 4: have spout hole that funnel-form stretches out, differently be provided with the expansion intercepting partial graph according to the drum shell of bulge-structure of the present invention of another kind of form with form shown in Figure 3;
Fig. 5: along the enlarged cross sectional view of a kind of arch projection of V-V hatching among Fig. 4;
Fig. 6: the view part that is provided with an a kind of base plate by bulge-structure of the present invention.
Laundry wheel shown in Figure 1 can be around axis 2 rotations of level of approximation at least.It is connected with a unshowned herein transmission device for this reason.The front of cylinder 1 is opened wide.It can or be sealed or be bearing on the fixing end plates (the two is not all expressed) with end plates that rotate together.Go up cylinder overleaf and firmly be connected with a base plate 3, driving moment can be imported this base plate into.Base plate has a kind of impression 4 of star, and it is just local here as seen, is used to increase the stability of base plate.It can be strengthened with a casting star structure of not expressing on its back side in addition.But cylinder 1 is formed by shell 5 substantially, and this shell is curved columnar and formed with connecting the securing lath of seam on a sightless herein position by a kind of.
In a coining tool, process a kind of bulge-structure before being deployed in of base plate 3 and drum shell 5 is connected with each other, also will illustrate below this structure.Projection 6 all is onesize on drum shell 5, and base plate 3 then also has maximum projection 8 on its maximum concentric line circle, and continues towards the center to have projection 9 to 15 on all less concentric line circles, and their diameter is littler step by step respectively.Thereby projection 6 can be arranged on the drum shell 5, projection 8 to 15 is arranged on the base plate 3, is in triangular arrangement respectively, as also being described in detail with following.
By the expansion of a part of drum shell 5 shown in Figure 2 as seen: by a kind of ball-and-socket shape from cylinder inwards projection 6 (see figure 3)s formed of the impression of punching out be arranged in the polygonal axis pattern of a rule, on just a kind of intersection point of triangular shaft line chart sample.This axis pattern determines that by concentric line 16 and two other axis 17 and 18 wherein concentric line 16 is parallel to the outer seamed edge 19 of drum shell lath.These two axis 17 and 18 respectively left to concentric line 16 partially than 60 ° of 60 ° or deflections to the right.All axis correspondingly have the copy that is parallel to each other and arranges, all have same spacing.So just formed many equilateral triangles, one of them (20) are represented with hacures herein, and its bight E, F and G are axis 16,17 and 18 or the intersection point of 18-2 simultaneously.This leg-of-mutton bisector 21 intersects with leg-of-mutton center of gravity, and this center of gravity is crosspoint 22 and the place of arranging a spout hole 23 respectively simultaneously.
By this structure between projection 6 under the center of gravity of triangle E, F, G-equally also formed herein triangle-position 24, this position has enough big area to arrange enough big spout hole 23, even owing to having between hole pattern and bulge-structure that biasing makes their position and not exclusively at the center, but spout hole can not cut off projection 6 circumference yet.This has improved the drum shell 5 with this spline structure or the rigidity of base plate 3; Because just interrupted its bending rigidity in the prior art in the perimeter line of cutting off the domes element thereby at the place, point of contact.Can clearly see this truth by Fig. 3.
Can be learnt by test: projection 6 each other spacing A are defined as 1/8 to 1/25 of its diameter, and preferably 1/10.Same to guarantee best clean result on the one hand, and when centrifugal dehydration, guarantee farthest to protect that clothing, the optimum value of this protruding 6 height H are 1/5 to 1/20 of projection diameter on the other hand simultaneously, preferably 1/12.Realize the clothing protection also relevantly with the spout hole diameter certainly when centrifugal dehydration, its optimum value can reach about 3.5 millimeters in the example shown.This value also is suitable for good discharge opeing, and this has given support by the good drainage between the projection 6.
The example of Shell Plate 5 design shown in the Figure 4 and 5 aspect the layout of bulge-structure and spout hole with identical according to the example of Fig. 2 and 3.The protection of the clothing when yet the structure of spout hole has been improved centrifugal dehydration.These spout holes 25 are arranged in 24 li 26 li of the baseplanes (Fig. 5) that are pulled outwardly the depressed part of making 27 in funnel-form, triangle position between the projection 6 for this reason.Thereby it is far just to be difficult to pierce 27 li of this depressed parts at the washing clothes of projection between 6 when centrifugal dehydration, thereby just arrive this spout hole; Say nothing of clothing and also can pass these spout holes, the arris of the danger on the outer rim in arrival hole 25.
This example has illustrated why compared with the prior art have so big advantage by circle of the present invention, oval or avette projection structure; The big triangle position 24 that forms in intersection point E, F, G place is the enough big spout hole 25 of laying, even for the subsidiary depressed part 27 of spout hole 25 usefulness provides the space, and can therefore for example not cut the circumference of arcuate configuration element 6.
The example of a kind of bulge-structure shown in Figure 6 has been represented the part of the thin plate of base plate 3 (Fig. 1).The outward flange 28 of base plate 3 is the external boundary that can lay that piece area of bulge-structure simultaneously.The inner boundary of this piece area is stipulated by line 29.The basic structure of male means and hole pattern is corresponding to the structure in Fig. 2 and 4.
Certain concentric line 30-1 herein and all its interior parallel lines 30-2,30-3 or the like is concentric circle corresponding to the axis among Fig. 2 16 being parallel under outward flange 28 states.Correspondingly other axis 31 and 32 (respectively departing from about 60 ° of concentric line 30-1 to the right or left) is towards the bending of aspect, the center of circle, thereby the leg-of-mutton sideline that is formed by them is along with more and more shortening near the center of circle, and this center of circle is positioned at being positioned on the crosspoint M at a distance of two radius R that draw.This means that be positioned at the more triangle F of the inside, K, the sideline F-K of L are smaller than triangle E, the F outside being positioned at more, the sideline E-F of G.Other comparable separately sideline is also all like this.The diameter of this outer lug 6 is also along with more and more littler near center of circle M, because interior concentric line 30-2 is shorter than outer concentric line (30-1) and therefore just has only short distance available for the projection 6 of equal number.This has also just illustrated the shortening in described triangle sideline and the bending of axial line 13 and 32.
Be used for lifting clothing when cylinder rotates if be provided with the follower of not expressing in according to laundry wheel shown in Figure 1 herein, corresponding bulge-structure also can have been designed in the surface of the sensing cylinder of this follower the inside so.This may be favourable when the certain way for the mechanical treatment of washing clothes.
Axis pattern shown in the present invention is not limited thereto.Other well-regulated axis pattern also can consider to be used to solve same technical problem.Therefore, for example a kind of rectangle of axis or particularly foursquare layout may be more favourable.Perhaps just can be in the square position between the projection under a stable condition, lay other leakage current hole or shallow hole and the mixing of funnel-shaped apertures.Also can use the mixed form of different well-regulated axis patterns.The arcuate configuration of this form also can be applicable to the laundry wheel of dry cleaner in addition.
