Definitions

  • the invention is based on, a tumble dryer with a laundry drum rotatably mounted about an at least approximately horizontal axis, which has a circular loading opening in the front floor, which is mounted on the inside of a front door frame of the housing and can be closed with a door pivotably mounted near the door frame.
  • Such a tumble dryer is known from German utility model 81 30 602.
  • the door frame on the housing-side loading opening is circular in shape and receives a pot filling the loading opening, which is attached symmetrically to the inside of the door panel.
  • the door is pivoted to the side and can be moved from right to left hinged. All you have to do is loosen the hinge from the front wall of the housing, turn the door plate together with the pan through 180 ° and reassemble the hinge on the other side of the loading opening on the front wall of the dryer housing. Appropriate mounting holes must of course be provided for this at the assembly point.
  • the circular loading openings are cut off in segments in their upper part and filled with a suitably shaped pot of the door.
  • the insertion opening for a filter frame is then provided on the lateral surface of the pot running along the chord, which is guided vertically downward within the pot from the end points of the chord.
  • the known shape of the enlarged loading opening allows the door stop to be moved only in that the hinge parts attached to the door are also moved to the other door edge.
  • the deep lower edge which is already located near the deepest inner drum surface, has proven to be disadvantageous because both items of laundry fall back or prematurely both when loading a larger item of laundry and when opening the door after the drying process has been completed fall out of the drum.
  • tumble dryers which are equipped with a front door which covers the entire width of the housing and extends deep to the ground, it is not possible to place a laundry basket under the loading opening before the door is opened, in order to catch laundry items that fall out.
  • the invention has for its object to provide a tumble dryer of the type mentioned in such a way that on the one hand a door stop change is possible by rotating the door by 180, so that the assembly effort when changing the door stop can remain low, that the screen area that can be installed is also enlarged and so that the flow rate can be reduced and that finally the lower edge of the loading opening is hardly arranged lower than with earlier, not enlarged loading openings.
  • the opening of the door frame has a shape at least approximating a rectangle, in which the sides form outwardly curved chords of an imaginary circumference around the opening and the corners have a curvature which is continuous to the side lines, but stronger in comparison thereto exhibit.
  • the shape of the loading opening is therefore very similar to the shape of a television screen and offers considerably more space for installing a lint filter. Almost the entire width and, as in the prior art, the entire height are available to this filter area.
  • the lower edge of the loading opening also forms an outwardly curved chord with respect to the laundry drum, the bow height of the inner contour of the drum shell being still sufficiently large to prevent laundry items loaded into the drum from falling easily out of the opened loading opening.
  • the shape of the loading opening which is basically symmetrical with respect to its vertical and horizontal center lines, also has the advantageous possibility of changing the door stop with little installation effort, as in the German utility model 81 30 602.
  • the filter frame which can be inserted into the rectangular body penetrating the loading opening and its guide arranged in the body is designed in such a way that it can be inserted from above in every door stop version and is held securely.
  • the tumble dryer shown in FIG. 1 has a control panel 1 on the front side in the upper region and a loading opening 2 arranged underneath, which is bordered by a door frame 3.
  • the inside of the door frame forms a circular bearing plate (not shown) for the circular loading opening of the drum 4.
  • the door 5 is pivotably mounted by means of two hinges 6. It carries a filler 7 on the inside, which has an opening on its upper side (not shown), which is filled by a flange 8 of a filter frame, not shown, which is inserted into the filler 7.
  • the surface of the packing 7 facing the drum 4 when the door is closed is perforated and serves on the one hand to allow air to pass through to the filter frame and on the other hand to reject the laundry falling around in the drum from the filter frame.
  • the hinges 6 on the right of the loading opening 2 are loosened, the door is rotated by 180 and the hinges 6 are mounted again at the fastening points 17.
  • a contour of the door frame 3 designed according to the invention is drawn in each case by the lines drawn very strongly in FIGS. 2 and 3.
  • this contour is very similar to the shape of a television screen with pages 9 and 10, which can be viewed as outwardly curved chords of an imaginary radius around a rectangle.
  • the sides 9 and 10 meet at the corners 11 and are here connected to one another by a constant curvature which is stronger than the curvature of the side lines.
  • the upper side 9 also indicates the top 8 of the packing 7, in the opening of which the filter frame, not shown, is inserted.
  • the shaft for the filter frame can at most be about as wide as the lines 12 indicated by a dashed line.
  • the thinner lines show the contour 13 of a known circular loading opening, from the circle of which a segment is cut off along the chord 14.
  • the dashed lines 15 indicate how wide a filter shaft in a packing of the known tumble dryer can be. From this comparative illustration it can be clearly seen that the area which can be covered by the fluff filter is considerably larger in the configuration of the loading opening according to the invention than in the prior art.
  • the variant shown in FIG. 3 for the shaping of the loading opening 2 likewise contains outwardly curved tendons as sides 9 and 10, which are arranged at the same distance from one another as in the example in FIG. 2. Only the corners 16 are shown in the variant in FIG 3 more rounded, ie they have smaller curvatures and thus shorten the diagonal of the loading opening.
  • the variant shown in FIG. 3 is more advantageous. It enables a smaller diameter of the end shield, which benefits the rigidity of the laundry drum due to a wider front ring and the safety and stability of the front drum bearing. Nevertheless, the good accessibility and visibility into the interior of the drum is maintained without having to accept the disadvantage that laundry items can fall out of the drum unintentionally because the lower edge of the loading opening would be too low compared to the low-lying part of the drum shell.
