Definitions

  • the invention relates to a dirt container for a vacuum cleaner with a trough-shaped lower part made of thermoplastic plastic and a hood-shaped upper part made of thermoplastic plastic placed tightly on this.
  • plastic containers are increasingly being used to collect the dirt, which can be produced particularly cheaply from two separate parts. It is known to connect the two parts of such a plastic container by using adhesives or by friction welding. However, friction welding is only possible if the containers have a circular cross
  • the embedding of a current-conducting bandage in the contact area makes it possible to induce a current in an alternating electromagnetic field in the current-conducting bandage and thereby heat the bandage and thus also its surroundings until the upper part and lower part are in contact with one another welded become. In this way, a completely uniform weld is obtained over the entire circumference and, after the contact area has cooled, a mechanical hardening in the contact area by inserting the current-conducting bandage. This prevents, for example, that the walls collapse inwards when a vacuum occurs in the dirt container.
  • the bandage can consist, for example, of carbon fibers, bandages made of metal are preferably used.
  • the bandage has the shape of a wire.
  • one of the two parts of the dirt container has an edge-parallel groove in the contact area, into which the bandage is inserted and which receives the edge of the other part. This will make production considerably easier. tert, also a reproducible quality of the weld is guaranteed.
  • the wall of the part having the groove can be thickened in the groove area, so that after the production of the weld seam in the area of the weld seam material reinforcement occurs which, together with the embedded and all-round bandage, ensures particularly effective stabilization of the wall area of the dirt container.
  • FIG. 1 shows a side view of a vacuum cleaner dirt container constructed from two parts
  • FIG. 2 shows an enlarged sectional view of area A in FIG. 1 during the production of the induction weld seam and
  • FIG. 3 a view similar to FIG. 2 after welding in the contact area.
  • the dirt collecting container 1 shown in the drawing is part of a vacuum cleaner, which is not shown in the drawing.
  • a dirt suction line is introduced into this protective collecting container, and a suction unit (not shown in the drawing) generates an underpressure in the dirt collecting container through an upper nozzle 2, through which the suction effect occurs.
  • the dirt collecting container 1 consists of a trough-shaped lower part 3 and a hood-shaped upper part 4.
  • the wall of the lower part 3 is thickened at the upper edge 5 and has a circumferential groove 7 in the area of this thickening 6.
  • a wire ring 8 is inserted into this groove 7, and the lower edge 9 of the upper part 4 is inserted into the groove 7 above the wire ring 8, the wall of the upper part 4 completely filling the groove 7 above the wire ring 8.
  • a current is induced in the wire ring 8 by means of an electromagnetic transmitter 10, which heats the wire ring 8.
  • the heat generated in it is radiated into the thermoplastic material of the upper part and the lower part and introduced so that the contact area of the upper edge 5 and the lower edge 9 is heated to such an extent that the thermoplastic material enters the ⁇ this contact area 11 melts and is welded together.
  • the upper part 4 and lower part 3 are thus intimately connected to one another in the contact area 11 and embed the wire ring 8, as is clear from the illustration in FIG. 3.
  • the contact area 11 on the one hand forms a thickening 6 in the wall of the dirt container 1, so that an increase in the mechanical stability already takes place due to this thickening.
  • the wire ring 8 is embedded in this thickened area, the stability again improved, that is to say, the combination effect of the material reinforcement and the inserted bandage results in a stiffening of the wall area of the container with a completely reliable sealing of the two parts of the container from one another.
  • the cross section of the dirt collecting container 1 can be chosen as desired, even with an irregular cross-sectional shape, the connection can be made as simply as desired if a wire ring 8 is inserted into a correspondingly shaped groove 7 corresponding to the shape of the groove 7 and then the same cross section as the lower part having the upper part is used.
  • a connection is also easily possible, for example, if projections or recesses are formed on the container.
  • an induction weld seam also makes it possible to dispense with connecting wires for resistance heating wires or the like, so that the wire ring 8 forming the bandage is completely embedded on all sides, and there are neither corrosion nor sealing problems as a result of container bushings.

Abstract

L'invention concerne un réservoir à poussières d'un aspirateur comportant une partie inférieure en forme de cuvette (3) et une partie supérieure en forme de capot (4) étroitement posé sur ladite partie inférieure, toutes deux en matière thermoplastique. Pour permettre une liaison fiable et de réalisation facile entre les parties supérieure et inférieure, et ce quelle que soit la section transversale du réservoir, il est proposé que dans la zone de contact (11) du bord supérieur (5) de la partie inférieure et du bord inférieur (9) de la partie supérieure soit disposé un câble (8) électriquement conducteur s'étendant le long des bords, et que les parties inférieure et supérieure soient durablement assemblées dans la zone de contact par un cordon de soudure par induction.
