- the attachment of the driver rib on the drum shell is still guaranteed and there can be no impurities or fluff in spaces between the embossing and driving rib.
- a laundry drum according to the invention for a water-conducting domestic appliance with a drum shell and at least one drum top surface imprints are applied to the laundry drum, wherein the edges of the embossments are formed elliptical.
- FIG. 1 is a perspective view of a washing machine according to the invention
- FIG. 2 is a perspective view of a washing drum according to the invention
- FIG. 3 is a plan view of a development of a drum shell
- FIG. 4 is a plan view of a development of a drum shell in a further embodiment
- FIG. 5 is a plan view of a development of the drum shell in a supplementary embodiment
- FIG. 6 is a view of an embossing underlying ellipse
- Fig. 7 shows a cross section of a washing drum according to the invention with imprints with quadrangular cross section and
- Fig. 8 shows a cross section of a washing drum according to the invention with embossments with arcuate cross-section.
- FIG. 1 shows a washing machine 1 according to the invention with a washing drum 6 according to the invention.
- the washing drum 6 according to the invention has a drum top surface 3 and a drum shell 2.
- embossments 4 are applied on the drum shell 2 .
- the edge of the imprints, d. H. the transition between the embossment 4 and the unembossed part of the washing drum 6, in particular the transition between the embossment 4 and the unembossed part of the drum shell 2 is elliptical.
- the drum shell 2 is still preferably driving ribs 5.
- the embossments 4 are directed inwardly to the washing drum 6. However, the embossments 4 may also be directed outwards.
- the shape of the edge of the embossing 4 need not exactly correspond to that of an ellipse in the mathematical sense.
- the elliptical embossings 4 may also have slightly different shapes from an ellipse in the mathematical sense.
- the embossments 4 are generally applied to the drum shell 2 both in the case of the washing machine 1 described in the exemplary embodiment or a washer-dryer (not shown) and in the case of a tumble dryer (not shown).
- the embossings 4 may also have a different size and / or a different shape in addition to the same shapes shown in Figures 3, 4 and 5.
- a different shape is understood to mean embossings 4 in which the ellipses underlying the embossing have different semi-axes a and b (FIG. 6).
- the large semi-axis a normally has a length in the range of about 5 to 15 mm and the small semi-axis b generally has a length in the range of 2.5 to 10 mm.
- the cross section of the embossings 4 may be arcuate or mono- or polygonal. In Fig. 7 is a cross section with a rectangular cross section and in Fig. 8 an embossing with arcuate cross-section shown.
- the radius of curvature and / or the slope of the cross section of the embossing may also be different.
- a relatively large pitch to the drum shell 2 may be present and on the other hand slowly decrease this slope towards the center of the elliptical embossing 4.
- the depth of the embossments is in a range of about 0.1 to 10 mm, preferably in a range of 0.5 to 5 mm.
- the embossings 4 are preferably arranged at a minimum distance, for example of 1 mm, to each other.
- a minimum distance for example of 1 mm
- the elliptical embossments are offset, correspondingly arranged as shown in Figures 3 to 5. Due to the offset more imprints 4 can be applied per unit area on the drum shell 3 and thus overall the effect of the embossing 4 can be increased.
- a washing drum 6 according to the invention with a drum shell 2 and a drum top surface 3 is shown.
- the washing drum 6 rotates about a drum axis 7 in the direction of rotation 8.
- the embossing 4 can also be aligned differently on the drum shell 2.
- 4 and 5 developments of the drum shell 2 are shown in plan view.
- the embossings 4 are arranged offset in each case in these figures.
- the large half-axis a of the embossment 4 underlying ellipse is perpendicular to the drum axis 7 and parallel to the direction of rotation 8.
- the arrangement in Fig. 4. is the large semi-axis a of the ellipse, which is the embossing 4 is based , perpendicular to the direction of rotation 8 and parallel to the drum axis 7.
- the large semi-axis a of the ellipse which is the elliptical embossing 4 is based, aligned at an angle ⁇ to the drum axis 7.
- the cross section 10 of the embossments 4 in the direction of the major axis a and the cross section 11 of the embossments 4 in the direction of the semi-minor axis b shown.
- FIGS. 3 to 5 the flood holes 9 which are generally present here are also shown.
- the flood holes 9 are preferably positioned between the embossments 4 or also in the embossments 4 (not shown).
- the flood holes 9 have a diameter of generally 1 to 4 mm and are arranged at a distance of about 2 to 20 mm from each other.
- the imprints have the advantage in a washing drum in a water-conducting household appliance that thereby the laundry drum is stiffened. As a result, material can be saved and due to the higher rigidity of the laundry drum 6 a noise reduction is achieved. Due to the surface structure applied by the embossing, scratches or other minor damage to the surface are barely visible in the interior of the laundry drum, resulting in a lower optical susceptibility of the laundry drum in a water-conducting domestic appliance according to the invention.
- an air flow forms between the embossments, so that overall the drying performance can be improved and increased.
- the existing air cushion between the imprints the laundry falls gently.
- the noise is reduced and the laundry is spared due to the muffled impact on the drum shell.
- part of the moisture of the laundry can diffuse into this air space or the air cushion. This increases the drying performance.
- the supplied drying air can thus take the moisture more easily, so that the drying performance is increased and the consumption of energy decreases.
