Definitions

  • the invention relates to a tumble dryer with a laundry drum which is rotatably mounted about an at least approximately horizontal axis and which has a circular loading opening in the front bottom, which can be closed with a door frame which is pivotably mounted near a front of the housing and whose opening has a shape which is at least approximated to a rectangle. which has on its inside a filler protruding into the opening of the window frame with a shape adapted to the window frame opening.
  • Such a tumble dryer is known from US 4,677,760.
  • a filling body projecting into the opening of the window frame is provided, in the drum-side receiving openings of which shoe hangers can be inserted. When not in use, these shoe hangers find space in the cavity of the packing.
  • the opening of the window frame and the Packings have at least two sharp corners, which will lead to problems when sealing the air duct.
  • the opening and the filler are also very high up in relation to the loading opening of the laundry drum and have only a small access area, so that the known dryer has unfavorable conditions for normal handling for drying clothes.
  • Another tumble dryer is known from German utility model 81 30 602.
  • the window frame at the housing-side loading opening is circular in shape and receives a pot-shaped filling body which fills the loading opening and is symmetrically attached 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 pot through 180 ° and re-mount the hinge on the other side of the window frame opening on the front wall of the dryer housing.
  • Appropriate mounting holes must of course be provided at the assembly point.
  • the circular window frame openings are cut off in segments in their upper part and filled with an appropriately shaped filler for the door.
  • the insertion opening is then on the lateral surface of the filling body running along the chord attached for a filter frame that is guided vertically downwards within the packing from the end points of the tendon.
  • the known shape of the enlarged window frame 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.
  • the invention has for its object to provide a tumble dryer of the type mentioned in such a way that on the one hand it is possible to change the door stop by rotating the door through 180 °, so that the assembly effort when changing the door stop can be kept to a minimum, that the screen area that can be installed is also increased and thus the flow rate decreased and that finally the lower edge of the window frame opening is arranged low enough for comfortable operation but hardly lower than with round, not enlarged window frame openings.
  • this object is achieved in that the laundry drum with its circular loading opening is mounted on a circular bearing plate formed on the inside of the window frame and that the side lines in the shape of the opening form outwardly curved chords of an imaginary circumference around the opening and the corners one to the Sidelines have a constant, but in comparison stronger curvature.
  • the shape of the window frame 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 window frame opening also forms an outwardly curved chord with respect to the laundry drum, the bow height of the inner contour of the drum shell is still large enough to prevent laundry items loaded into the drum from falling easily through the opened window frame opening.
  • the shape of the window frame 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 filler body penetrating into the window frame 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 window frame opening 2 arranged underneath, which is bordered by a door frame 3.
  • the inside of the window 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 on the inside a filler 7 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 Air passage to the filter frame and on the other hand the rejection of the laundry falling around in the drum from the filter frame.
  • the hinges 6 on the right of the window frame opening 2 are loosened, the door is rotated by 180 ° and the hinges 6 are re-installed at the fastening points 17.
  • a contour of the window frame 3 designed according to the invention is drawn by the lines drawn 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 are connected to one another at the corners 11 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 lint 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 formation of the Window frame opening 2 also 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 more rounded in the variant in FIG. 3, ie they have smaller ones Curvatures and thus shorten the diagonals of the window frame 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 accidentally fall out of the drum, because the lower edge of the window frame opening is arranged too low compared to the low-lying part of the drum shell would.
