Definitions

  • the invention relates to a washing machine drum for a drum washing machine or a washer-dryer, which can be rotated in a tub around an essentially horizontally arranged axis of rotation and has hollow drum ribs with a substantially V-shaped basic profile on its inner casing and the drum ribs being fastened to the drum casing by means of a seam connection are.
  • a washing machine drum is already known from DE-GM 19 88 023, in which the drum ribs are fastened to the drum shell by means of a fold connection.
  • the fastening form and construction form of a drum rib in the drum casing shown in this prior art provides for the drum rib to be fastened to the drum with a substantially V-shaped profile by means of a number of mirror-image fastening straps arranged by means of a fold connection.
  • a washing machine drum is described in DE-GM 67 53 532, the drum ribs of which have catches on their base edges for fastening by means of a fold connection and which are additionally fastened to the drum shell by a securing plate.
  • a flexible contact bead in the area of the rib end faces is intended to avoid the formation of a gap between the rib and drum elements.
  • a drum for a washing machine is known in which the profile of the drum rib is formed in one piece from the drum shell.
  • Scooping devices are assigned to the ribs on the drum circumference.
  • the rib has water outlet openings directed towards the inside of the drum.
  • the ribs In order to raise the washing liquid from the lower region of the tub and to trickle it down onto the laundry, according to one embodiment of this application, the ribs have a circular crest with rib ribs adjoining it in a V-shape. This rib shape, which resembles a keyhole in cross-section, is suitable for the transport of washing liquid.
  • the drum with the ribs molded in one piece from the drum shell is not suitable for high spin speeds. As a result of the items of laundry lying against the drum shell under the influence of centrifugal force and the forces acting on the shell and rib, a drum of this type would be severely deformed.
  • the stability of the drum with the ribs formed from the drum shell and the rib profile with the circularly shaped crest is, for example, for high speeds. B. not sufficient when spinning.
  • the invention has for its object to provide a washing machine drum of the type mentioned with a stable, designed for higher drum speeds and simple to manufacture drum rib.
  • the solution according to the invention has the advantage that the drum rib can be used at higher loads due to higher spin speeds due to the design of the rib profile. Furthermore, the arrangement of the fastening elements enables the rib to be securely fastened in the drum and simple assembly in devices provided for this purpose.
  • the design of the rib does not require any additional elements for securely fastening the rib in the drum casing and for avoiding the formation of gaps between the rib and the drum casing.
  • the drum rib Due to the bead created at the base of the rib, the drum rib can rest against the drum shell in this area during the fastening process and thereby compensate for manufacturing tolerances.
  • the washing machine drum of a washing machine or washer dryer is designated by (1).
  • a drum rib (3) is fastened in the drum jacket (2) by means of a fold connection.
  • the fastening tabs (4) and the associated longitudinal slots (5) are arranged to the right and left of the axial center line of the washing machine drum (1).
  • the fastening tabs (4) of the drum rib (3) which are arranged opposite one another, are arranged offset and encompass the drum casing (2) in the area of the longitudinal slots (5) in a claw-like manner. This ensures that the drum rib (3) is securely fastened in the drum casing (2) even with a higher number of spins.
  • the bottom line of the bottom edge (6) of the drum rib (3) is step-shaped to adapt to the inner contour of the drum shell.
  • bottom edges (6) of the drum rib (3) are designed as beads (7) with the fastening tabs (4) adjoining them.
  • the fastening tabs (4) are guided through the corresponding longitudinal slots (5) and folded into a claw shape on the outer casing of the drum.
  • the bottom edge (6) of the drum rib (3) is pressed against the contour of the inner drum shell, the design of the bottom edge (6) as a bead (7) making it possible to compensate for manufacturing-related dimensional and dimensional tolerances.
  • the bead (7) forms a U-shaped pocket on the bottom edge (6) of the drum rib, which is more or less compressible.
  • FIG. 3 shows the particularly advantageous design of the rib profile, the drum rib (3) being formed from a U-shaped crest (8) with rib webs (9) adjoining it in a V-shape, and the bottom edges (6) of which are in the form of beads ( 7) are trained.
  • FIG. 3 shows water inlet openings (10) on the drum shell (2) and water outlet openings (11) in the drum rib (3). Furthermore, FIG. 3 shows embossments (12) for increasing the stability, which run from the crest (8) over the rib webs (9) to the edge of the bead (7). To guide a stud, not shown, impressions (13) are provided on the crest.
