Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the media such as detergents, dishwashing detergents and bleaches and, if appropriate, heating steam
  • the feed lines in known washing machines are usually introduced into the drum as a tube bundle or in the form of concentric tube e , but the support on the drum wall causes difficulties and a support on the unloading side can hinder unloading.
  • the tube bundle even if housed in a hollow shaft, can impair the washing process.
  • the object of the invention is to provide a device for introducing liquid and / or gaseous media which enables the pipelines to be fastened to the drum wall, is simple in construction and has little wear.
  • This device is installed in a housing pot or a pot-like housing and the individual annular chambers are formed by partitions which are kept at a distance by means of the spacers, the inner wall of the pot-like housing delimiting the annular chamber from the outside.
  • the axial line feeds are passed through the partitions or screwed into threaded holes in the partitions, and the radial line ducts to the annular chambers are provided in the housing.
  • annular chamber spaces are formed by annular grooves in annular disks of the first and second types; the ring discs of the first type have channels which are connected to the axial pipelines, whereas the Ring discs of the second type are connected to the radially extending connections, or vice versa.
  • annular chambers are thus formed, to which the media are fed in the axial direction via the pipe connections and from which the media are led out via radial pipe connections in the radial direction.
  • the partition walls can be rotated relative to one another within the housing, and in the second solution, the ring disks of the first type can be rotated relative to the ring disks of the second type, whereby they are arranged alternately with respect to one another and of which the ring disks of the first type or the ring disks second Type are rotatably connected to each other so that all the first type washers can twist relative to the second type washers. It is thereby achieved that the device can be attached to the washing machine in such a way that the axially extending lines are rotated, whereas the radially extending lines are arranged in a stationary manner, and vice versa.
  • FIG. 3 shows a sectional view through a device according to a first exemplary embodiment of the invention.
  • the device comprises a plurality of annular disks which are coaxially assigned to one another, namely an annular disk 10 of the first type, followed by an annular disk 11 of the second type, followed by an annular disk 12, which is similar to the annular disk 10, and then another annular disk 11 of the second type and as a conclusion an annular disc 13, which is similar to the annular discs 10 and 12.
  • the annular disk 10 has an annular groove 14 on one end face
  • the annular disk 11 has annular grooves 15 and 16 on both end faces
  • annular grooves 17 and 18 are attached to the annular disk 12, similarly to the annular disk 11, and is also on the annular disk 13 an annular groove 19 is provided on one side.
  • annular grooves 14 and 15 of the annular disks 10 and 11 define an annular chamber 20; the annular grooves 16 and 17 of the washers 11 and 12 form a further annular chamber 21; A third ring chamber 22 is formed between the two ring disks 12 and 11 and a fourth ring chamber 23 is formed between the two ring disks 11 and 13 on the right.
  • FIG. 1 shows a perspective view of the annular disk 12, with the annular groove 17 and a central opening 24.
  • the annular disks 10 and 13 are similar to the annular disk 12 according to FIG. 1; the only difference is that the ring disk 12 has annular grooves on both end faces, whereas the ring disks 10 and 13 each have an annular groove only on one end face. All ring disks 10, 12 and 13, which are referred to as first ring disks or as ring disks of the first type, have lugs 25 with bores 26 which are uniformly distributed on the circumference are assigned such that they cannot be rotated relative to one another.
  • the annular disk 12 as can be seen from FIG. 1, has two radial channels 27a and 29, which each end in radially extending connecting elements 28, one channel 27a via an axial opening 30 into the annular groove 17 and the other channel 29 via an axial opening 31 opens into the annular groove 18.
  • the annular disk 11 of the second type is drawn in a perspective illustration in FIG. 2. It is shown in such a way that the end face in which the annular groove 16 is introduced is considered.
  • a channel 32 which runs in the axial direction and opens a connection between the annular groove 16 and a radial one, opens into this annular groove 16 like channels 27a and 29, of
  • Forms channel 33 which is drilled on / outside and is closed on the outside by means of a threaded plug 34.
  • the radially extending channel 33 ends on the inside in a bore 35 which opens to the end face with the annular groove 15 and into which a pipe connection piece 36 is connected. It can be seen from FIG. 3 that the opening or bore 32 on one end face and the opening or bore 35 on the other side, the latter with the annular groove 15, opens.
  • a second radial channel 37 is drilled from the outside inwards, offset by 60 degrees, and is closed on the outside with a sealing plug 38.
  • the channel 37 is connected to the annular groove 15 by means of a transverse bore 39 and opens inside in a bore 40 which is open towards the same end face and into which a further pipe 42 is connected by means of a threaded intermediate piece 41 or reducing ring 41.
  • the further tube 42 is smaller in diameter than the tube 36. If the reducing ring 41 were not provided, the outer diameter of the tube 36 could be exactly as large as that of the tube 42.
  • the annular disc 11 also has four further openings 43 in a central region 44 which, in contrast to the bores 35 and 40, completely penetrate the central region 44 and together with the two bores uniformly on the outer edge of the inner region 44, that is to say within the through the annular grooves 15 and 16 limited area are distributed. These openings 43 and bores 35 and 40 together surround a central opening or a central bore 45.
  • the bores 35 and 40 are not continuous, but only open into the radial channels 37 and 33; there is of course also the possibility of designing these bores continuously and closing them on the opposite side by means of threaded plugs similar to the threaded plugs 34 and 38.
  • the washer 11 on the right which is therefore between the washers 12 and 13, is designed exactly like the washer on the left with the channels 39 and the threaded plug 38 and the threaded plug 34; it is only installed 120 degrees or 180 degrees apart.
