Definitions
- the present invention relates to a basket for a washing machine, dryer, and the like.
- a drilled basket which is intended to accommodate the laundry to be washed, is pivotally arranged within a tank containing the lye. Due to the rotational movement of the basket, the laundry is agitated and caused to spin in the lye, and the lye is carried upwards by the rotating basket, from where it falls on the laundry which results to be completely immersed and soaked, such that the impurities are transferred to the washing and rinsing lye.
- the basket is usually provided with dragging blades, which are arranged on the side wall of the basket.
- the dragging blades considerably increase the total friction between the rotating basket and the laundry, and thus the dragging capability of the basket. This results in a greater movement of the laundry, which enhances its contact with the lye and consequently improves the washing results.
- the movement intensity of the laundry directly depends on, besides the basket rotation speed, the size and number of dragging blades, and thus on the total friction between the basket and laundry.
- the object of the present invention is thus to provide a basket for washing machines, washer-dryers or dryers having a great capability of moving the laundry and effectively loosening any tangle.

- the rear or bottom wall 8 of the basket 6 is preferably a substantially plane, centrally drawn, steel disk, being concave towards the outside of the basket.
- a support hub 4 for the basket In the middle of the rear wall 8 of the basket 6, there is mounted a support hub 4 for the basket, the basket being operatively connected therethrough to motor means (not shown), which control the rotation of the same about the longitudinal axis X.
- the side wall 7 of the basket is preferably obtained from a generally flat steel sheet, which is folded such as to form an approximatively rotational surface about a longitudinal central axis, being coincident with the longitudinal axis X of the tank 3 when in use.
- the coupling of the bottom 8 and front 9 walls to the side wall 7 is preferably provided by folding two end tracts 18, 19 of the sheet being the side wall 7, such as to give a C-shaped profile to the steel plate at both ends thereof.
- the bottom 8 and front 9 walls are shaped such as to define, at the respective outer edges, complementary profiles with the C-shaped profile formed at both end tracts 18, 19 of the side wall 7.
- the basket 6 comprises at least one dragging blade 5 being preferably arranged on the side wall 7 of the basket 6.
- the dragging blade 5 forms a dragging surface 12 longitudinally extending along a curved line, wherein said curved line comprises a first curvature in an hypothetical development surface 13 of the side wall 7 and, preferably, a second curvature in a projection of the dragging blade 5 on a surface perpendicular to the axis of rotation X.
- the first curvature and the second curvature of the longitudinal course of the dragging surface 12 can comprise either gradual and/or sudden curvature.
- the first curvature of the dragging surface is a curvature having a substantially constant bending radius (Fig. 2, 3, 4, 5, 24).

- the ratio L14/L15 of the length L14 of the parallel tract 14 to the length L15 of the curved tract 15 ranges between 0.8 and 4.0, preferably 2.0 and 3.5, still more preferably about 3. This implies a main rotational movement about the axis X in the area of the basket which corresponds to the parallel tract 14 of the blades and a main rotational movement about axes transversal to the axis X in a different area of the basket, i.e. in the area where the inclined or curved tract 15 of the blade extends.

- This length ratio has proved to be universally applicable to baskets of different depths and volumes.
- the first dragging blade 5' has a greater height than the height of the second dragging blade 5".
- height of the dragging blade is meant the extension of the blade in the radial direction relative to the axis X of the basket.
- a ratio H5' / H5" of the height H5' of the first dragging blade 5' to the height H5" of the second dragging blade 5" ranging between 1,05 and 1,25, preferably about 1,17 has proved to be advantageous.
- the first dragging blade 5' and the second dragging blade 5'' overlap to each other in an overlapping (central) area 16 of the basket 6.
- the depth P16 of the overlapping area 16 depends on the lengths L5', L5" of the blades 5' and 5" and on the depth P6 of the basket and advantageously ranges between about 9/22 L5' ... 8/11 L5' (L5' being the length of the first dragging blade 5').
- the dragging blades 5, 5' , 5'' have a lower extension in the direction parallel to the axis of rotation X than the extension of the side wall 7 of the basket. This allows using a limited number of dragging blades having a determined size for a wide range of baskets of different depths.
- the dragging blade/s 5 are arranged by being spaced away from the front wall 9 of the basket, thereby avoiding excessive stress to the laundry items which may occur when they are in sliding contact with the porthole of the washing machine and are also simultaneously engaging a dragging blade which rotates together with the basket relative to the porthole.
- the dragging blade/s 5 can be arranged by being spaced away from the rear wall 8 of the basket. This allows, on the one hand, the shape of the blades to be defined independently of the shape of the rear wall 8, and on the other hand, to avoid the formation of recesses which facilitate the accumulation of residues of detergent and in which small pieces may be entangled, such as tangled handkerchiefs, which have not been deployed during washing or drying.
- the height of the dragging blades 5, 5', 5'' varies either gradually and/or suddenly along the longitudinal extension thereof.
- the height H5' of at least one 5' of the dragging blades 5, 5', 5'' is maximum in the vicinity of the front wall 9 of the basket 6 and decreases, preferably gradually, as it moves away from front wall 9.
- the height H5" of at least one 5" of the dragging blades 5, 5', 5" is the greatest in the vicinity of the rear wall 8 of the basket and decreases as it moves away from said rear wall 8.
- the alternating arrangement of dragging blades with an opposite height course results in the main action of lifting the laundry at the front and rear walls of the basket and in the main action of rotation and deployment of the laundry in the middle area of the basket.
- the height H5' , H5'' of the dragging blades has a wave-like course characterized by double curvature, or in other words by a concave tract and a convex tract.
- the dragging blade 5 has a further active surface, the so-called sliding surface 17, opposite the dragging surface 12.
- the bias of the dragging surface 12 relative to the side wall 7 of the basket is greater than the bias of the sliding surface 17 relative to this side wall 7, wherein the inclination angle a12 of the dragging surface 12 preferably ranges between 45° and 90°, advantageously between 60° and 90°, still more advantageously this angle a12 is about 75°.
- the inclination angle a17 of the sliding surface 17 ranges between 15° and 85°, preferably between 25° and 35°, still more preferably this angle a17 is about 30°.
- Such a shape of the dragging blades allows the "active" blades to be selected by means of the direction of rotation of the basket.
- the dragging blade/s define a longitudinally convex side and a longitudinally concave side opposite the longitudinal convex side and the dragging surface 12 is formed on the longitudinally convex side and the sliding surface 17 is formed on the longitudinally concave side of the blade.
- Such a shape of the blades results in an unusual combination between the axial movement (along the axis of rotation X of the basket) and the more or less strong lifting movement of the laundry as a function of the bias of the active surfaces 12 and 17.
- the inclination angles a12 and a17 of the dragging 12 and sliding 17 surfaces are substantially equal to each other.
- a further embodiment provides that the dragging surface 12, and preferably also the sliding surface 17 are developed along a curved line comprising two subsequent curvatures in opposite directions in the hypothetical development surface 13 of the side wall 7 of the basket.
- a so-formed dragging blade preferably has a first tract 20 substantially parallel to the axis of rotation X which extends to the vicinity of the front wall 9 of the basket and a second tract 21 substantially parallel to the axis of rotation X which extends to the vicinity of the rear wall 8 of the basket, as well as a curved tract with double curvature 22 which connects said first 20 and second 21 parallel tracts to each other.
- the height H5 of the dragging blade 5 advantageously has maximum values in the vicinity of the front wall 9 and rear wall 8 of the basket and decreases, preferably gradually, to a turn point 23 of the curvature of the dragging blade 5.
- an embodiment provides that two dragging blades are arranged either in opposite positions relative to the axis of rotation X (see for example Fig. 13) or in diametrally opposed positions relative to the axis of rotation X and a middle plane of the basket, perpendicular to the axis of rotation X (see for example Fig. 14).
- a further embodiment provides three dragging blades to be distributed at a substantially constant 120° angular pitch (Fig. 22, 23).
- dragging blades are advantageously arranged at and preferably connected to reinforcement ribs 24 (schematically designated by means of dotted lines in Fig. 23) of the basket support structure.
- the dragging blade/s 5 In order to avoid that the variation in the height of the dragging blade 5 entails excessive sharpness and thus undesired wear of the laundry to be washed and/or dried, it is advantageous to provide the dragging blade/s 5 with a width B (transversal both to the longitudinal extension and height of the blade) which gradually decreases in the longitudinal direction of the blade.
- the dragging blades 5 define a space 25 therein, which is suitable to contain washing liquid and one or more drain ports 26, which are preferably formed in the dragging surface 12 and/or sliding surface 17, which allow the washing liquid to be released from said space 25 within the basket.
- These drain ports 26 are preferably holes or slots, the axial extension thereof being substantially perpendicular to a base plane 27 of the blade 5, and at least approximatively radial to the axis of rotation X of the basket.
- each blade has a root portion 28 which is enlarged relative to a dragging portion 29 that forms the dragging surface 12.
- the dragging blades 5 comprise an end portion 30 facing the rear wall 8 or front wall 9 of the basket and being inclined to the inside of the basket, such that an upper longitudinal ridge 31 of the blade has a lower length than the length of the base thereof.
- This end surface 30 is substantially triangular or trapezoid and preferably convex, i.e. it has a slight increase in height.
- the upper longitudinal ridge 31 becomes gradually shorter, from the end surface 30 to the height of the base of the dragging blade.
- Fig. 19 shows an embodiment in which only the dragging surface 12 shows such a curved course, particularly longitudinally concave, and on the other hand, the opposite sliding surface 17 has a substantially rectilinear longitudinal course.
- the side wall 7 of the basket 6 has one or more radially enlarged areas 32 that are preferably arranged such as to move the barycentre of the containment space 10 to the rear wall 8 of the basket in order to obtain a reduction in the flexion of the loaded basket and an increase of the overall immersion volume of the basket under the liquid level in the tank 3.
- the radially enlarged areas 32 are preferably defined by steps 33 which increase the basket rigidity.
- the radially enlarged areas 32 are formed between one or more longitudinal tracts 34 without steps, which substantially extend from the rear tract 18 of the side wall 7 for connection to the rear wall 8 to the front tract 19 of the side wall 7 for connection to the front wall 9.
- the dragging blades 5, 5', 5" are connected to these longitudinal tracts 34.
- the dragging blades can be used with a substantially flat fixing base and traditional fixing means, for example screws or snap-fitting portions.

- the longitudinal tracts 34 have a radial distance decreasing from the axis of rotation X to the front wall 9 of the basket 6.
- a preferred embodiment of the invention provides a dragging blade with such a curvature along its longitudinal extension as to give the laundry, in addition to the well known lifting movement, a further movement in the longitudinal direction of the basket. This greatly contributes to a better mixing of the laundry during washing and drying while preventing the individual items (particularly the delicate ones) from remaining for a long time in areas greatly exposed to the mechanical action of the basket.
- This curved blade 5 has, as is known, a plurality of drain ports 26 for the lye to pass therethrough, which is accumulated in the lower part of the tank and released when the blade 5 is in a raised position.

Abstract
Description
- The present invention relates to a basket for a washing machine, dryer, and the like.
- With particular reference to the known washing machines, a drilled basket, which is intended to accommodate the laundry to be washed, is pivotally arranged within a tank containing the lye. Due to the rotational movement of the basket, the laundry is agitated and caused to spin in the lye, and the lye is carried upwards by the rotating basket, from where it falls on the laundry which results to be completely immersed and soaked, such that the impurities are transferred to the washing and rinsing lye.
- To enhance the washing efficiency, the basket is usually provided with dragging blades, which are arranged on the side wall of the basket. The dragging blades considerably increase the total friction between the rotating basket and the laundry, and thus the dragging capability of the basket. This results in a greater movement of the laundry, which enhances its contact with the lye and consequently improves the washing results.
- With the baskets and blades of the known art, the movement intensity of the laundry directly depends on, besides the basket rotation speed, the size and number of dragging blades, and thus on the total friction between the basket and laundry.
- However, neither the size of the dragging blades nor the rotational speed of the basket can be arbitrarily increased, since, because of the centrifuge force and large-sized blades' peculiarity of dragging whole tangles of laundry without loosening them, such an increase would only result in the laundry to be flattened against the basket side wall. This sets "natural" limits to the capability of known baskets of causing the laundry to spin and effectively loosening any tangle of laundry.
- The object of the present invention is thus to provide a basket for washing machines, washer-dryers or dryers having a great capability of moving the laundry and effectively loosening any tangle.
- A further object of the present invention is to provide a basket for washing machines, dryer-washers or drying machines suitable to impart a very intense movement to the laundry, without the laundry being exposed to excessive wear due to the friction between the basket and the laundry.
This and other objects are achieved by means of a basket for washing machines, which comprises a basket wall, which defines a containment space for accommodating the laundry and at least one dragging blade arranged on the basket wall, in which said dragging blade forms a dragging surface, which extends longitudinally along a curved line, in which said curved line comprises a curvature in a hypothetical development surface of the basket wall. - Due to the curvature characteristics of the dragging blade, the basket according to the invention provides the laundry with a combination of the following movements:
- - revolution movement of the laundry about the axis of rotation of the basket;
- - rotational movement of the tangles of laundry about axes parallel to the axis of rotation of the basket;
- - translational movement of the laundry about the axis of rotation of the basket;
- - rotational movement of the tangles of laundry about axes transversal to the axis of rotation of the basket,
- which implies an unusual loosening effect on the tangles of laundry and agitation of the latter without increasing the wear of the laundry during washing and drying.
- In order to better understand the invention and appreciate the advantages thereof, some embodiments will be described herein below, with reference to the annexed figures, in which:

- Fig. 28 is a bottom perspective view of the dragging blade as shown in Fig. 27.
- In Fig. 26, a front-loading washing machine with biased-axis tank is schematically shown. Particularly, the washing machine, which is generally designated with 1, comprises a
cabinet 2, atank 3 being housed therein, which consists of a generally cylindrical body, either made of plastic or stainless steel, with either biased or horizontal longitudinal axis X (as shown in Fig. 26). Thetank 3 is coupled to thecabinet 2 by means of known means, which comprise shock absorbers and suspension springs, which are not shown in order to avoid burdening the drawing. - The
tank 3 is provided with a front aperture 35, having a generally round shape, which can be closed by means of a porthole being frontally hinged to thecabinet 2 and not shown, as known per se. Within thetank 3, abasket 6 is housed rotatably about the axis X, for the laundry to be accommodated therein to be washed and/or dried. Thebasket 6 comprises aside wall 7, a rear orbottom wall 8 and afront wall 9. Thewalls inner space 10 intended to accommodate the laundry to be washed and/or dried. Thefront wall 9 of thebasket 6 is a stainless steel or plastic ring, with anaperture 11 having a generally round shape, which is placed such as to match theaperture 5 of thetank 3 to provide access to theinner space 10 to load/unload the laundry. - The rear or
bottom wall 8 of thebasket 6 is preferably a substantially plane, centrally drawn, steel disk, being concave towards the outside of the basket. In the middle of therear wall 8 of thebasket 6, there is mounted a support hub 4 for the basket, the basket being operatively connected therethrough to motor means (not shown), which control the rotation of the same about the longitudinal axis X. - The
side wall 7 of the basket is preferably obtained from a generally flat steel sheet, which is folded such as to form an approximatively rotational surface about a longitudinal central axis, being coincident with the longitudinal axis X of thetank 3 when in use. - The coupling of the
bottom 8 and front 9 walls to theside wall 7 is preferably provided by folding twoend tracts side wall 7, such as to give a C-shaped profile to the steel plate at both ends thereof. Thebottom 8 andfront 9 walls are shaped such as to define, at the respective outer edges, complementary profiles with the C-shaped profile formed at bothend tracts side wall 7. - The
basket 6 comprises at least onedragging blade 5 being preferably arranged on theside wall 7 of thebasket 6. Thedragging blade 5 forms adragging surface 12 longitudinally extending along a curved line, wherein said curved line comprises a first curvature in anhypothetical development surface 13 of theside wall 7 and, preferably, a second curvature in a projection of thedragging blade 5 on a surface perpendicular to the axis of rotation X. - In order to obtain a greater movement for the laundry, the first curvature and the second curvature of the longitudinal course of the dragging
surface 12 can comprise either gradual and/or sudden curvature. - In accordance with an embodiment, the first curvature of the dragging surface is a curvature having a substantially constant bending radius (Fig. 2, 3, 4, 5, 24).
- Advantageously, the
blade 5 is oriented such as to comprise, along the longitudinal extension thereof, aparallel tract 14 extending substantially parallel to the axis of rotation X of thebasket 6 and atract 15, either curved or biased, which extends along directions either inclined or transversal to the axis of rotation X. - The ratio L14/L15 of the length L14 of the
parallel tract 14 to the length L15 of thecurved tract 15 ranges between 0.8 and 4.0, preferably 2.0 and 3.5, still more preferably about 3. This implies a main rotational movement about the axis X in the area of the basket which corresponds to theparallel tract 14 of the blades and a main rotational movement about axes transversal to the axis X in a different area of the basket, i.e. in the area where the inclined orcurved tract 15 of the blade extends. By dividing the basket into areas of different movements of the laundry, the problem of the laundry forming tangles during the washing is effectively avoided. - In accordance with an embodiment (Fig. 3, 6, 13) the
parallel tract 14 of thedragging surface 12 is arranged adjacent to thefront wall 9 of thebasket 6. Alternatively, thisparallel tract 14 can also be arranged in the vicinity of therear wall 8 of the basket, such as shown in Fig. 22. - Trials have been also successfully carried out with baskets (Fig. 7, 8, 9, 10, 14) with at least one first dragging blade 5', the parallel tract of which 14 extends either substantially to or at least in the vicinity of the
front wall 9 of the basket and asecond dragging blade 5" , theparallel tract 15 of which extends either to or at least in the vicinity of therear wall 8 of the basket.
In these embodiments, the movement of the laundry, particularly for small-sized items, is very irregular and the deployment of the items and loosening of tangles have been both very satisfactory. - In accordance with an embodiment, as shown for example in Fig. 8, 9 and 10, the first dragging blade 5' has a greater length than the
second dragging blade 5", in which the ratio L5'/L5 " of the length L5' of the first dragging blade 5' to the length L5" of the second dragging blade 5'' preferably ranges between 1,05 and 1,25, still more preferably is about 1,16. This length ratio has proved to be universally applicable to baskets of different depths and volumes. - In accordance with a further embodiment, the first dragging blade 5' has a greater height than the height of the
second dragging blade 5". In the present description, by "height of the dragging blade" is meant the extension of the blade in the radial direction relative to the axis X of the basket. Particularly, a ratio H5' / H5" of the height H5' of the first dragging blade 5' to the height H5" of thesecond dragging blade 5" ranging between 1,05 and 1,25, preferably about 1,17 has proved to be advantageous. - As may be seen for example in Fig. 8 and 9, the first dragging blade 5' and the second dragging blade 5'' overlap to each other in an overlapping (central)
area 16 of thebasket 6. The depth P16 of the overlappingarea 16 depends on the lengths L5', L5" of theblades 5' and 5" and on the depth P6 of the basket and advantageously ranges between about 9/22 L5' ... 8/11 L5' (L5' being the length of the first dragging blade 5'). - Advantageously, the
dragging blades 5, 5' , 5'' have a lower extension in the direction parallel to the axis of rotation X than the extension of theside wall 7 of the basket. This allows using a limited number of dragging blades having a determined size for a wide range of baskets of different depths. - In accordance with an embodiment, the dragging blade/
s 5 are arranged by being spaced away from thefront wall 9 of the basket, thereby avoiding excessive stress to the laundry items which may occur when they are in sliding contact with the porthole of the washing machine and are also simultaneously engaging a dragging blade which rotates together with the basket relative to the porthole. - Alternatively or in addition to, the dragging blade/
s 5 can be arranged by being spaced away from therear wall 8 of the basket. This allows, on the one hand, the shape of the blades to be defined independently of the shape of therear wall 8, and on the other hand, to avoid the formation of recesses which facilitate the accumulation of residues of detergent and in which small pieces may be entangled, such as tangled handkerchiefs, which have not been deployed during washing or drying. - In accordance with a further embodiment, the height of the
dragging blades 5, 5', 5'' varies either gradually and/or suddenly along the longitudinal extension thereof. With reference to the embodiments shown by way of example in Fig. 7, 8, 9 and 10, the height H5' of at least one 5' of thedragging blades 5, 5', 5'' is maximum in the vicinity of thefront wall 9 of thebasket 6 and decreases, preferably gradually, as it moves away fromfront wall 9. - Alternatively, or preferably, in addition to what has been described above, the height H5" of at least one 5" of the
dragging blades rear wall 8 of the basket and decreases as it moves away from saidrear wall 8. The alternating arrangement of dragging blades with an opposite height course results in the main action of lifting the laundry at the front and rear walls of the basket and in the main action of rotation and deployment of the laundry in the middle area of the basket. - Advantageously, the height H5' , H5'' of the dragging blades has a wave-like course characterized by double curvature, or in other words by a concave tract and a convex tract.
- In addition to the dragging
surface 12, thedragging blade 5 has a further active surface, the so-called slidingsurface 17, opposite the draggingsurface 12. Depending on the direction of rotation of thebasket 6, either the draggingsurface 12 or the slidingsurface 17 act on the laundry, wherein the pulling effect of these active surfaces depends on the shape and inclination of the surface relative to theside wall 7 of the basket. In accordance with an embodiment of the invention, the bias of the draggingsurface 12 relative to theside wall 7 of the basket is greater than the bias of the slidingsurface 17 relative to thisside wall 7, wherein the inclination angle a12 of the draggingsurface 12 preferably ranges between 45° and 90°, advantageously between 60° and 90°, still more advantageously this angle a12 is about 75°. The inclination angle a17 of the slidingsurface 17 ranges between 15° and 85°, preferably between 25° and 35°, still more preferably this angle a17 is about 30°. Such a shape of the dragging blades allows the "active" blades to be selected by means of the direction of rotation of the basket. - Particularly advantageously, the dragging blade/s define a longitudinally convex side and a longitudinally concave side opposite the longitudinal convex side and the dragging
surface 12 is formed on the longitudinally convex side and the slidingsurface 17 is formed on the longitudinally concave side of the blade. Such a shape of the blades results in an unusual combination between the axial movement (along the axis of rotation X of the basket) and the more or less strong lifting movement of the laundry as a function of the bias of theactive surfaces - Alternatively, the inclination angles a12 and a17 of the dragging 12 and sliding 17 surfaces are substantially equal to each other.
- A further embodiment (Fig. 1 and 16) provides that the dragging
surface 12, and preferably also the slidingsurface 17 are developed along a curved line comprising two subsequent curvatures in opposite directions in thehypothetical development surface 13 of theside wall 7 of the basket. A so-formed dragging blade preferably has afirst tract 20 substantially parallel to the axis of rotation X which extends to the vicinity of thefront wall 9 of the basket and asecond tract 21 substantially parallel to the axis of rotation X which extends to the vicinity of therear wall 8 of the basket, as well as a curved tract withdouble curvature 22 which connects said first 20 and second 21 parallel tracts to each other. In this case, the height H5 of thedragging blade 5 advantageously has maximum values in the vicinity of thefront wall 9 andrear wall 8 of the basket and decreases, preferably gradually, to aturn point 23 of the curvature of thedragging blade 5. - As regards the arrangement of a plurality of dragging blades within the
basket 6, an embodiment provides that two dragging blades are arranged either in opposite positions relative to the axis of rotation X (see for example Fig. 13) or in diametrally opposed positions relative to the axis of rotation X and a middle plane of the basket, perpendicular to the axis of rotation X (see for example Fig. 14). - On the other hand, a further embodiment provides three dragging blades to be distributed at a substantially constant 120° angular pitch (Fig. 22, 23).
- In any case, several or all of the dragging blades are advantageously arranged at and preferably connected to reinforcement ribs 24 (schematically designated by means of dotted lines in Fig. 23) of the basket support structure.
- In order to avoid that the variation in the height of the
dragging blade 5 entails excessive sharpness and thus undesired wear of the laundry to be washed and/or dried, it is advantageous to provide the dragging blade/s 5 with a width B (transversal both to the longitudinal extension and height of the blade) which gradually decreases in the longitudinal direction of the blade. - In accordance with an embodiment, the
dragging blades 5 define aspace 25 therein, which is suitable to contain washing liquid and one ormore drain ports 26, which are preferably formed in the draggingsurface 12 and/or slidingsurface 17, which allow the washing liquid to be released from saidspace 25 within the basket. These drainports 26 are preferably holes or slots, the axial extension thereof being substantially perpendicular to abase plane 27 of theblade 5, and at least approximatively radial to the axis of rotation X of the basket. - In order to facilitate the fixing of the
dragging blades root portion 28 which is enlarged relative to a draggingportion 29 that forms the draggingsurface 12. - In accordance with an embodiment, as shown for example in Fig. 17, 18 and 24, the
dragging blades 5 comprise anend portion 30 facing therear wall 8 orfront wall 9 of the basket and being inclined to the inside of the basket, such that an upperlongitudinal ridge 31 of the blade has a lower length than the length of the base thereof. Thisend surface 30 is substantially triangular or trapezoid and preferably convex, i.e. it has a slight increase in height. In the embodiment as shown in Fig. 21, the upperlongitudinal ridge 31 becomes gradually shorter, from theend surface 30 to the height of the base of the dragging blade. - While in the embodiments described above the
whole dragging blade surface 12 shows such a curved course, particularly longitudinally concave, and on the other hand, the opposite slidingsurface 17 has a substantially rectilinear longitudinal course. - Advantageously, the
side wall 7 of thebasket 6 has one or more radiallyenlarged areas 32 that are preferably arranged such as to move the barycentre of thecontainment space 10 to therear wall 8 of the basket in order to obtain a reduction in the flexion of the loaded basket and an increase of the overall immersion volume of the basket under the liquid level in thetank 3. The radially enlargedareas 32 are preferably defined bysteps 33 which increase the basket rigidity. - In accordance with an embodiment, the radially
enlarged areas 32 are formed between one or morelongitudinal tracts 34 without steps, which substantially extend from therear tract 18 of theside wall 7 for connection to therear wall 8 to thefront tract 19 of theside wall 7 for connection to thefront wall 9. Advantageously, thedragging blades longitudinal tracts 34. As no steps are to be considered, the dragging blades can be used with a substantially flat fixing base and traditional fixing means, for example screws or snap-fitting portions. - The attached figures show embodiments in which the
longitudinal tracts 34 comprise either one or more substantially longitudinal tracts that are rectilinear and parallel to the axis of rotation X or, alternatively, one or.morelongitudinal tracts 34 that are substantially helical, i.e. transversal in thehypothetical development surface 13 of theside wall 7 of the basket. - With a substantially truncated-cone shaped basket, the
longitudinal tracts 34 have a radial distance decreasing from the axis of rotation X to thefront wall 9 of thebasket 6. - With reference to Fig. 27 and 28, a preferred embodiment of the invention provides a dragging blade with such a curvature along its longitudinal extension as to give the laundry, in addition to the well known lifting movement, a further movement in the longitudinal direction of the basket. This greatly contributes to a better mixing of the laundry during washing and drying while preventing the individual items (particularly the delicate ones) from remaining for a long time in areas greatly exposed to the mechanical action of the basket.
- This
curved blade 5 has, as is known, a plurality ofdrain ports 26 for the lye to pass therethrough, which is accumulated in the lower part of the tank and released when theblade 5 is in a raised position. Preferably, thesedrain ports 26 comprise a first set of holes arranged along thelongitudinal ridge 31 of the blade and a second set of holes arranged at an (either front or rear) end of theblade 5 such as to enhance the feeding of lye within the basket in the vicinity of this end as compared with the remaining areas of the blade. - Due to the characteristics of the
basket 6 described above, both the movement of the laundry and the effect of loosening the tangles of laundry can be increased while washing and drying with the friction between the basket and laundry being equal. The basket according to the invention is, thus, particularly suitable for washing and drying very dirty delicate laundry and, in any case, the basket according to the invention allows enhancing and speeding up washing and drying methods of the laundry with the dirt level being equal. - While the invention has been described by means of embodiments in which the dragging blades has uninterrupted surfaces, the invention relates as well to embodiments in which the shape and arrangement of the dragging
surface 12 and slidingsurface 17 of the blades are reproduced by means of a plurality of discrete partial surfaces spaced apart from each other.
