Definitions

  • the invention relates to a concrete ring as a counterweight for the tub one Washing machine with a U-shaped cross-section, one-sided open ring part that with a concrete-containing mass is poured and on the outer circumference one with the Connectable connecting device is provided.
  • Such a concrete ring is known from GB 2 044 298 A.
  • the concrete mass is in there cast an annular box shape, the bottom of which also serves as the front end wall for the tub.
  • the known shape laid out individually and poured with concrete.
  • the designed and poured out Molds have to be stored in a suitable storage place until the concrete has hardened are spread over a wide area and therefore take up a large area.
  • the invention has for its object a concrete ring as a balance weight on the tub to train a washing machine so that a continuous production of the Concrete ring is possible and takes up as little space as possible for curing.
  • the required number of concrete rings can be poured continuously become.
  • the bearings required for the hardening of the concrete rings Area can be significantly reduced by stacking the U-shaped ring part is trained.
  • a stable stacking of the concrete rings is namely achieved in that bead-shaped depressions are formed on the free edges of the U-legs of the ring part are and on the outside of the bottom of the ring part at the height of the diameter of the U-leg of the ring part, corresponding to the shape of the bead-shaped depressions Elevations are formed. So that the cast and get on top of each other stacked concrete rings over their interlocking beads and elevations one against the other immovable position.
  • connection flange By means of this connecting flange, the Concrete ring either through a screw connection or through one over the Outer periphery of the connecting flange and the outer periphery of a similar provided on the connection flange provided clamping ring be connected to the tub.
  • a reinforcement part required for the strength of the concrete ring can be thereby bring in a simple manner in the concrete ring that in the space between one or more reinforcement parts for the two U-legs of the ring part load-bearing base are inserted. It is advantageous if the base is in one piece are integrally formed on the bottom of the U-shaped ring part.
  • Adequate support of the reinforcement parts during pouring of the concrete ring is achieved in that the base at its free end with a several receiving openings for the reinforcing part or parts are provided.
  • the strength of the wall parts of the U-shaped ring part is increased in that Support webs are provided on the outside of the U-legs of the ring part are.
  • a stable stacking of the concrete rings is achieved in that on the free edges the U-leg of the ring part are bead-shaped depressions and on the outside of the bottom of the ring part at the height of the diameter of the U-legs of the ring part, the shape of the bead-shaped depressions corresponding surveys are formed.
  • the U-shaped can advantageously Ring part formed as the end wall closing the tub his. This saves the otherwise usual end wall of the tub. It is appropriate that the annular bottom of the ring part itself extends beyond the inner U-leg to the center of the ring part and encloses the filling opening of the washing machine.
  • the ring part 1 is U-shaped in its cross section.
  • the two U-legs 2 and 3 form an outer and an inner peripheral wall which together define an annular space with the bottom 6 of the U-shaped ring part 1.
  • This annular space is filled with a mixture in the Concrete is included and which forms a concrete ring 7 after hardening.
  • about the circumference of the U-shaped ring part 1 is distributed several in the ring Space between the U-legs 2 and 3 protruding, in one piece on the bottom 6 molded base 8 provided.
  • the bases 8 have at their free end 9 a receiving opening 10 for a reinforcement ring 11.
  • This reinforcement ring 11 is before pouring the U-shaped ring member 1 into the receiving opening 10 of the base 8 inserted so that it when pouring the U-shaped ring part 1 is enclosed by the sealing compound and the concrete ring 7 after it has hardened gives a higher strength.
  • the ring parts 1 can be stacked one above the other according to FIG. 2.
  • the stacking can happen before or after pouring the annular spaces of the ring parts 1.
  • Around To be able to stack the ring parts 1 already unfilled is one or more Place the outer and / or the inner U-legs 2 and 3 a pouring opening intended.
  • the casting compound can be stacked in this pouring opening State of the U-shaped ring parts 1 are introduced into the annular space.
  • the U-legs 2 are on the free edges 13 and 3 embossed depressions 14 each. On the outside of the Bottom 6, however, are at the height of the diameter of the U-legs 2 and 3 lying elevations 15 formed. When stacking the ring parts 1 these elevations each engage in the bead-like depressions 14 below lying ring part 1 and thus secure the stacked one above the other U-shaped ring parts 1 against slipping.
  • the ring parts 1 form so-called lost molds; separate, reusable Molds are therefore unnecessary. Therefore also when pouring of the individual concrete rings 7 no curing time can be waited for the casting mold to be available again.
  • the stackability of the ring parts 1 for the necessary to harden the cast concrete rings 7 storage of Ring parts 1 required a significantly smaller storage area. This also applies to one possible storage of the concrete rings 7.
  • a radially outward connecting flange 16 On the ring part 1 is also a radially outward connecting flange 16 molded.
  • this connecting flange 16 By means of this connecting flange 16, the ring part 1 on the Tub 17 of a washing machine can be attached.
  • a possible type of attachment is indicated in Fig. 1.
  • a screw 18 Tensionable clamping ring 19 around the outer circumference of the connecting flange 16 and a similarly formed connecting flange 20 of the Tub 17 placed.
  • the clamping ring 19 has oblique flanks 21 on, so that the two connecting flanges when tensioning the clamping ring 19 16 and 20 are axially pressed against each other by the flanks 21.
  • the ring part 1 is so overall trained that it has the function of a front-end washing machine front end wall of the tub 17 takes over. For this reason a sealing element 22 between the two connecting flanges 16 and 20 inserted. When tightening the clamping ring 19, the connecting flanges 16 and 20 pressed against this sealing element 22, so that the tub 17 is adequately sealed on its end face.
  • the U-shaped ring part 1 is also a radially in from the inner U-leg 3 delimited space 23 extending wall part 24 is formed.
  • this wall part 24 is designed as a filling opening 25 of the washing machine. From the edge of this opening 25 an obliquely rising one extends Flange 26 on which a sealing sleeve 27 is fastened in a known manner the connection to the filling opening provided on the housing 28 of the washing machine 29 manufactures.
  • the U-shaped ring part 1 takes the place of the otherwise required front wall of the tub 17.
  • the front wall of the The tub 17 and the balance weight are therefore in one piece with each other connected.
