DETAILED DESCRIPTION

(8) The embodiments herein will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. Disclosed features of example embodiments may be combined. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.

(9) FIG. 1 illustrates a dishware supporting arrangement 1 arranged on a rack 3. The rack 3 is arranged within an interior of a dishwasher 5. The rack 3 is mounted in the dishwasher 5 in a known manner, and therefore not described in detail. The rack main extension plane m1 is a plane in which the rack 3 substantially extends and along which the rack 3 is displaceable, e.g. in a typical case of an upper rack, in and out of the dishwasher 5 for facilitating removal and insertion of dishware onto the rack 3. If a position of the rack 3 within the dishwasher 5 or outside of the dishwasher 5 is changed, a change of a position of the rack main extension plane m1 occurs as a consequence thereof. When the dishwasher 5 is placed in a normal operating position, the rack main extension plane m1 coincides with a horizontal plane.

(10) As illustrated in FIG. 1, the dishware supporting arrangement 1 comprises a mesh structure 7 having a structure main extension plane m2. The structure main extension plane m2 extends along a plane in which the mesh structure 7 substantially extends. The mesh structure 7 may comprise, e.g. be made of, a plastic material as for example a polymer, or coated steel. The mesh structure 7 may be manufactured in one piece, for example by molding.

(11) The dishware supporting arrangement 1 according to FIG. 1 comprises a tilting mechanism 13 arranged to allow the mesh structure 7 to be titled around at least one axis between a first position and a second position described in detail in conjunction with FIG. 3.

(12) According to FIG. 2a, the mesh structure 7 comprises a first plurality of ribs 9 connected to a second plurality of ribs 11. For simplicity only two of the first plurality of ribs 9 and the second plurality of ribs 11 have been marked. The first plurality of ribs 9 is connected to the second plurality of ribs 11 at connection portions 4. Each rib of the first plurality of ribs 9 is connected to at least one other rib of the first plurality of ribs 9 and to at least one of the second plurality of ribs 11. In similar way each of the second plurality of ribs 11 is connected to at least one other of the second plurality of ribs 11 and to at least one of the first plurality of ribs 9.

(13) As illustrated in FIG. 2a the first plurality of ribs 9 extends along a first plane n1 and the second plurality of ribs 11 extends along a second plane n2. In other words, the first plurality of ribs 9 extends along the first plane n1 in that the first plurality of ribs 9 extends in directions within the first plane n1 or in directions being parallel to the first plane n1, but at a distance from the first plane n1. In a similar way the second plurality of ribs 11 extends along the second plane n2 in that the second plurality of ribs 11 extends in directions within the second plane n2 or in directions being parallel to the second plane, but at a distance from the second plane n2.

(14) The first plane n1 is arranged at a first angle a1 in relation to the structure main extension plane m2 and the second plane n2 is arranged at a second angle a2 in relation to the structure main extension plane m2. The first angle a1 and the second angle a2 may for example be in a range of 5-45°. The first angle a1 and the second angle a2 may be equal or may be different.

(15) The first plurality of ribs 9 has a first length d1 and the second plurality of ribs 11 has a second length d2. The first length d1 and second length d2 may be equal or may be different. The first length d1 and second length d2 may for example be in a range of 5-200 mm.

(16) FIG. 2b illustrates a top view of the mesh structure 7 in FIG. 2a and FIG. 1. As can be seen the mesh structure is created by the first plurality of ribs 9 connected to the second plurality of ribs 11 forming squares connected to each other. The first plurality of ribs 9 is connected to the second plurality of ribs 11 at a first rib angle c1. The first plurality of ribs 9 or the second plurality of ribs 11 are connected to each other at a second rib angle c2.

(17) In FIG. 2b only angle c2 between two of the second plurality of ribs 11 is illustrated. However, two of the first plurality of ribs 9 may also be connected at an angle with the same value as the second rib angle c2. The first rib angle c1 and the second rib angle c2 may be in a range of 90-150°. According to some embodiments the top view of the mesh structure may have different patterns as for example the first plurality of ribs 9 may be connected to the second plurality of ribs 11 forming rhombs connected to each other. The mesh structure 7 may be rotated around an axis A1. According to the embodiments illustrated in FIG. 2, the axis A1 is arranged along a longer side of the structure 7. However the axis A1 may be positioned at any other positions at the mesh structure 7.

(18) FIG. 3 illustrates a more detailed side-view of the dishware supporting arrangement 1 shown in FIG. 1. As mentioned, the dishware supporting arrangement 1 comprises the tilting mechanism 13, which is arranged to allow the mesh structure 7 to be titled, i.e. rotated around at least one axis A1 between the aforementioned first position p1 and the aforementioned second position p2. The tilting mechanism 13 may comprise a track (not shown) and the mesh structure 7 may comprise a protrusion (not shown) adapted to move along the track. Thus, a user may displace the structure 7 between the first position p1 and the second position p2 e.g. by pulling or pushing by hand at the mesh structure 7. Thereby, the protrusion may be caused to move along the track while the mesh structure 7 tilts, or at least partly rotates, around the axis A1.

(19) Further, the tilting mechanism 13 may be arranged to hold the mesh structure 7 in the first position p1 and in the second position p2 by a first stop mechanism (not shown) arranged to stabilize the mesh structure 7 in the first position p1, and by a second stop mechanism (not shown) arranged to stabilize the mesh structure 7 in the second position p2. The first and second stop mechanisms may be realized by any known stop mechanisms, such as a snap grip or the like.

(20) At the first position p1, the structure main extension plane m2 is arranged at a third angle a3 in relation to the rack main extension plane m1, and at the second position p2 the structure main extension plane m2 is arranged at a fourth angle a4 in relation to the rack main extension plane m1. According to the embodiments illustrated in FIG. 3, the fourth angle a4 is greater than the third angle a3. The third angle may be in a range of 6-45° and the fourth angle a4 may be in a range of 75-90°.

(21) At the first position p1, the mesh structure 7 is arranged to support dishware intended to be washed in the dishwasher. The dishware, such as cups, glasses or silverware, may be placed on the mesh structure 7 at the first position p1 of the mesh structure 7. The mesh structure 7 further comprises a supporting side 15 adapted to support the dishware.

(22) As illustrated in FIG. 3, each of the first plurality of ribs 9 and each of the second plurality of ribs 11 are inclined in relation to the rack main extension plane m1 at the first position p1 and at the second position p2. Thereby, the washing fluid, such as water-drops, flows along the first plurality of ribs 9 and the second plurality of ribs 11 downwards due to gravity which improves draining, i.e. running off of washing fluid from the mesh structure and dishware during a drying phase of a program cycle of a dishwasher. The draining of the washing fluid is improved both in the first position p1 of the mesh structure 7 and at the second position p2. At the second position p2 the mesh structure 7 has been tilted, i.e. rotated around the axis A1 in a direction shown as counter clockwise in relation to the first position p1 in FIG. 3. At the second position p2, the mesh structure 7 is in an idle position, i.e. at the second position p2 the mesh structure is not intended to support any dishware.

(23) According to the embodiments illustrated in FIG. 3, the first angle a1 and the second angle a2 are less than the third angle a3. Thus, each rib of the first plurality of ribs 9 and each rib of the second plurality of ribs 11 are inclined in relation to the rack main extension plane m1 at the first position p1 and at the second position p2 and at all positions between the first position p1 and the second position p2. Alternatively, the first angle a1 and the second angle a2 may be greater than the third angle a3, but still the first angle a1 and the second angle a2 should be different from the third angle a3. Further, the first angle a1 may be less than the third angle a3 and the second angle a2 may be greater than the third angle a3.

(24) FIG. 4 illustrates a cross section of two ribs across a line A-A in FIG. 2b. Each of the first plurality of ribs 9 and the second plurality of ribs 11 has a cross sectional profile that may be shaped as a rhomb. Further, the cross sectional profile may be symmetrical or asymmetrical in relation to axis S1 and S2. The first plurality of ribs may have different cross sectional profile than the second plurality of ribs.

(25) Each of the first plurality of ribs 9 and the second plurality of ribs 11 may comprise an upper tip 6. Due to the upper tips 6 of the mesh structure 7, the dishware supported by the mesh structure 7 at the first position have smaller contact area with the mesh structure 7 compared to when the cross sectional profile has an even and substantially horizontal supporting side 15 of the mesh structure 7. By this, draining, i.e. running off, of washing fluid from the dishware and from the mesh structure is facilitated. As an effect drying process of the dishware is improved.

(26) According to some embodiments the cross sectional profile of each of the first plurality of ribs 9 and the second plurality of ribs 11 may comprise a tip 17 pointing opposite to a direction from the support side 15 and away from the support side 15. With other words, opposite in relation to the upper tips 6. Thereby, forces keeping the washing fluid at the ribs are reduced and by this, the draining of the washing fluid from the ribs is improved.

(27) FIG. 5 illustrates a projection of the first plurality of ribs and the second plurality of ribs of the structure onto a plane B perpendicularly orientated with respect to the at least one axis A, which plane B is illustrated in FIG. 2b. The projection illustrated in the FIG. 5 forms a zig-zag pattern. In this manner, accommodation of for example knives intended to be washed on the structure is facilitated.

(28) Even though embodiments of the various aspects have been described, many different alterations, modifications and the like thereof will become apparent for those skilled in the art. The described embodiments are therefore not intended to limit the scope of the present disclosure.
