Definitions

  • the invention relates to a fastening device for in the tub of a washing machine built-in heating rods, which device one at the bottom of the tub has attached support plate on which the heating elements are held.
  • Such a fastening device is known from DE-A-38 32 144.
  • a fastening device is known from DE-A-38 32 144.
  • a device is a attached to the bottom of the tub of a washing machine Carrier part provided, to which a separate spring clip attaches is.
  • the heating rods are formed by the spring clip against the support part Support beads held down.
  • Such a device requires a high manufacturing and assembly costs, since the carrier part and the spring clip in different Manufacturing processes must be manufactured separately and then assembled.
  • the invention has for its object in a fastening device of the beginning described way to significantly reduce the manufacturing and assembly costs.
  • the object is achieved according to the invention in that on the support plate at least one integral with this and opposite the plane the support plate is provided vertically or approximately vertically projecting retaining tab is, which has a push-through opening receiving the heating rods, the Heating rods by contacting at least one of the edges of the push-through opening or one or more beads formed on the carrier plate are held.
  • the Heating rods For attaching the heating elements in the tub only need the support plate on Bottom of the tub to be attached. The heating rods are then in the Push-in opening of the retaining tabs are inserted and are thus ready for use.
  • the carrier plate is a stamped and bent part on which the through-hole provided retaining tab is formed by bending processes, the support plate can produce in one piece in a particularly simple manner.
  • the heating rods can be held well achieve without further effort that at the free end of the retaining tab a provided with a pressure edge, at least approximately parallel to Level of the support plate extending pressure arm is formed, the light vertical distance between the pressure edge and the associated edge of the Through opening or the point of contact on the beads is slightly smaller than that Diameter of the heating rods.
  • Such a sliding seat can be carried out in a structurally simple form in that L-shaped overlapping the longitudinal edges of the carrier plate at the bottom of the tub Hooks are provided.
  • the carrier plate 1 On the carrier plate 1 are two holding tabs each provided with a push-through opening 2 3 molded in one piece.
  • the carrier plate 1 is advantageously together with the holding tabs 3 designed as a stamped and bent part. In the stretched state of a metal strip openings are first punched out at the appropriate locations after bending up the holding tabs 3 form the through openings 2. Outdoors End of the retaining tabs 3 are also press arms 4 also during the bending process molded. By cranking the free end 5 of the pressure arms 4 there is one Pressing edge 6 formed.
  • the bend is carried out so that the clear vertical distance 7 between the Pressing edge 6 and the associated edge 8 of the push-through opening 2 slightly is smaller than the diameter of the heating rods 9 of the washing machine.
  • the Andes Retaining tabs 3 molded, at least approximated to level 10 of the carrier plate 1 parallel pressure arms 4 have due to their geometric design a certain elasticity so that when the heating rods 9 are inserted into the through opening 2 dodge something and thus exert a pressing force on the heating elements 9.
  • L-shaped hooks 12 are provided on the wall of the tub 11. These hooks 12 can optionally be integrally formed on the tub 11. This is especially possible if the tub 11 is made of plastic.
  • the carrier plate 1 only needs to be pushed under the L-shaped hook 12 and is thus attached to the tub 11. This is both a simple assembly the manufacture of the washing machine as well as easy disassembly at a customer service possible.
  • the tub 11 offers Bottom of the tub 11 continuously closed support plate 1 also a thermal protection for the plastic material of the tub 11, since it is the Radiant heat of the heating rods 9 prevents.
  • the one-piece design of the carrier plate 1 together with the holding tabs 3 connection technologies such as e.g. Rivet connections by so-called Tox rivets, which injures the surface or the structure of the material of the carrier plate 1 would be changed. Structural changes or injuries could lead to quality problems (e.g. rusting).
  • connection technologies such as e.g. Rivet connections by so-called Tox rivets, which injures the surface or the structure of the material of the carrier plate 1 would be changed. Structural changes or injuries could lead to quality problems (e.g. rusting).
  • At least one tab cut out of the push-through opening can also be shaped as a mounting element.
  • a tab across Heating rod direction be prismatic, so that a ridge line of this prism as Contact edge for the heating element (s) 9 forms the edge 8 of the push-through opening 2 or replaced.
  • a second such tab could be on an upper transverse edge the push-through opening to be shaped in accordance with the pressure arm 4 and with a pressure edge 6 clamp the heating element (s) 9 from above against the lower edge 8.
