Definitions

  • the invention relates to a tumble dryer with a lockable by a door laundry drum and a lint filter device.
  • a tumble dryer removes water from the wet laundry in its laundry drum by circulating hot air through the laundry drum in an air circuit.
  • Wäscheflusen entrained.
  • a lint filter device which is arranged in an exhaust duct from the laundry drum and which, for. may consist of a solid frame member with a Siebgewebebeposition. This lint filter device should be cleaned by the user after each drying operation to remove the retained lint from the screen fabric tension.
  • the document JP 03092196 discloses a clothes dryer with a lint filter device on the drum rear side.
  • the document DE 295 17 898 U1 describes a filter bag as a lint filter device in the base space of a tumble dryer.
  • the described lint filter devices have the disadvantage that they can be cleaned by the user only laboriously.
  • the tumble dryer is thus equipped with a lint filter device in an air duct of an air circuit running through the laundry drum.
  • the lint filter device contains at least one filter bag.
  • the filter bag has a bag interior and a bag opening through which the process air is introduced into the bag interior.
  • the process air leaves the bag interior through its walls, which have a filter membrane, so that entrained Wäscheflusen and other objects are at least largely retained and thus removed from the air circulation.
  • the filter bag is arranged on the door of the tumble dryer, whereby it is easily accessible to the user.
  • the filter bag serves as a lint storage or catch container for Wäscheflusen, e.g. in that the bag interior extends from below as seen from the bag opening. After completion of the drying process, laundry fluff collected in the filter bag can thus not fall out due to the action of gravity.
  • the filter bag is arranged as part of the lint filter device in a filter chamber on the door of the clothes dryer, said filter chamber preferably having an air inlet opening and an air outlet opening arranged thereunder.
  • the lint filter device is configured such that the user at least parts of it, e.g. can pull the filter bag itself out of a lint filter holder on the door of the clothes dryer, e.g. up. This improves the accessibility of the lint filter device by the user and at the same time ensures easier mounting.
  • the filter bag is attached with its bag opening at an air passage opening of a partition wall.
  • This partition together with a wall of the door, e.g. an outer wall, the filter chamber in the door, in which the bag interior of the filter bag is arranged during operation.
  • This partition incl.
  • the filter bag may preferably be arranged to be pulled out in the lint filter holder on the door of the tumble dryer.
  • the filter bag can be easily removed by the user from the partition and replaced. Thus, a more effortless cleaning or a more convenient replacement of the filter bag is made possible.
  • the filter bag includes a plurality of single bags arranged one inside the other.
  • the bag interior of the innermost single bag is thus arranged in the bag interior of the next single bag, etc.
  • the bag openings of the individual bags are connected to each other.
  • the process air then flows through the bag opening of the filter bag into the bag interior of the innermost single bag and leaves it through its walls, which have a first filter membrane.
  • a part of the entrained Wäscheflusen and other objects is retained.
  • Arrived in the bag interior of the second single bag the process air now flows through the walls of this second single bag, which include a second filter membrane.
  • the filter membranes of the individual bags preferably have decreasing mesh sizes, which leads to an improved filter effect.
  • a laundry drier 1 has a laundry drum 1 for receiving the laundry 92 to be dried.
  • the laundry drum 1 can, after filling in the wet laundry 92, be passed through a door 2 (FIG. Fig. 1 and 2 ) are closed.
  • the user of the device starts the drying program, eg by pressing a button on a control panel 91 of the tumble dryer.
  • a controller 99 of the tumble dryer then takes control of the steps of the drying program described below.
  • the laundry drum 1 is rotated by a drive (not shown) in one or in alternating directions and the washing 92 located in the laundry drum 1 is loosened up and mixed.
  • process air 12 is blown through a fan 96 in a preferably closed circuit through the laundry drum 1 and the laundry 92 located therein.
  • the process air 12 can still be heated by a heater 95 before entering the laundry drum 1.
  • the warm process air 12 sorbs moisture in its passage through the wet laundry 92, which is removed from the laundry 92 and discharged from the laundry drum 1.
  • To remove this moisture from the process air 12 is for example a heat exchanger device consisting of a first stage 93 for cooling the process air 12 and a second stage 94 for reheating the process air 12.
  • the process air 12 in the first stage 93 condenses water from the process air 12, which is thus not reintroduced into the air circuit and the laundry drum 1.
  • the process air 12 passes back to the fan 96 and the air circuit is thus closed.
  • the door 2 is kept closed during the entire drying process.
  • Wäscheflusen 17 During the passage of the process air 12 through the laundry drum 1 with the laundry located therein 92, however, not only moisture is discharged or carried in the process air stream, but also so-called. Wäscheflusen 17 and possibly other foreign bodies. In the following, when we speak of "purgatives,” such "foreign bodies" are explicitly included. These Wäscheflusen 17 must before the passage of the process air 12 through the above-mentioned assemblies 93 to 96 are removed from the process air 12 in order to avoid impairments of the efficiency or even damage or other impairment of the modules.
  • a lint filter device 4 which comprises a filter bag 5, which is arranged on the door 2 of the tumble dryer, i. the filter bag 5 is attached or held on or in the door 2.
  • the filter bag 5 has at least one bag opening 6 and at least one bag interior 70, the wall of which contains a filter membrane 50.
  • the filter bag 5 is flowed through by the process air 12 from the bag opening 6 in the direction of the bag interior 70.
  • Wäscheflusen 17 disturbing Wäscheflusen 17 are retained at least to a large extent and thus removed from the flow of process air 12.
  • Various materials may be used as filter membrane 50, conceivable are e.g. Nonwoven materials, cotton fabrics, filter papers, mesh fabrics or other materials which are flexible, air permeable and suitable for convenient air filtration.
  • the filter bag 5 is attached to the door 2 of the tumble dryer so that it extends from its bag opening 6 ago with its bag interior 70 extends downwards.
  • Such an arrangement has the advantage that the Wäscheflusen 17 are held by the action of gravity in the bag interior 70 and 96 can not fall out even after switching off the fan.
  • the volume of the filter bag 5 may be so dimensioned that the filter bag 5 does not have to be cleaned after each drying operation, but - depending on the lint content of the laundry to be dried and the amount of laundry - eg only after a few drying operations or loads.
  • Such an embodiment of the present invention saves the user the tedious cleaning the lint filter device 4 after each drying process, as is necessary in tumble dryers with conventional lint filter devices.
  • Preferred volumes of the filter bag 5 are in a range of 2200 to 2500 cm 3 .
  • Such filter bag 5 allow the inclusion of Wäscheflusen 17 of, for example, 5 to 10 loads (with normal lint content of the laundry to be dried).
  • the depth of the bag interior 70 is at least 100% of the cross-section of the bag opening 6 from its lower edge, i. in particular, such a "deep bag” can not be equated with a screen fabric tension on a frame component that sags in the air stream.
  • At least the filter bag 5 of the lint filter device 4 may be designed as a disposable item, so that it can be easily disposed of with household waste after complete filling of its bag interior 70 with laundry bags 17.
  • no cleaning of the filter bag 5 is necessary at all, which saves the user of the clothes dryer time and effort and allows a hygienic operation.
  • the filter bag 5 may preferably be arranged in a filter chamber 8 on the door 2 of the tumble dryer.
  • this filter chamber 8 may have an inlet opening 9 and a separate outlet opening 10 for the process air 12 flowing through it and the filter bag 5.
  • the inlet opening 9 is preferably located above the outlet opening 10, ie the filter space 8 is flowed through by the process air 12 from top to bottom.
  • the flow direction of the process air 12 can be better controlled than if an open filter bag were used.
  • the filter bag 5 occupy a large part of the height of the door 2 and a lint filter holder 3 on the door 2, whereby large bag volumes are made possible.
  • the filter chamber 8 is bounded on one side by a wall of the door, e.g. towards the front by an outer wall 11 of the door 2.
  • a partition 13 which has a passage opening 14 for the flowing into the filter bag 5 process air 12.
  • the filter bag 5 is then fastened with its bag opening 6 to this passage opening 14 of the partition wall 13, preferably in such a way that it is connected on the one hand as airtight as possible with the partition wall 13 and on the other hand easily, e.g. can be loosened and re-attached by the user without the use of tools.
  • Various attachment methods are conceivable, e.g. a flange on the partition wall 13, to which the bag opening 6 of the filter bag 5 is pressed by means of an elastic band or another mechanism.
  • a part of the lint filter device 4, for example the partition wall 13, with the filter bag 5 attached to it, can be configured such that it can be pulled out by the user in a lint filter holder 3 on the door 2 of the tumble dryer.
  • Such embodiments have the advantage that the easy accessibility for the user a simple cleaning or a simple replacement of the filter bag 5 is possible. Furthermore, can be largely avoided by a pull-out attachment of the partition wall 13 in the lint filter holder 3 that Wäscheflusen 17 are passed on the filter bag 5.
  • the lint filter holder 3 is mounted as a cylinder-like bulge on the door 2 laundry drum side.
  • the partition wall 13 has a grip element 27, at its passage opening 14 is the bag opening 6 of the Filter bag 5 attached (see FIGS. 5 and 6 ). For cleaning, this complete assembly can be conveniently pulled out of the lint filter holder 3 by the user.
  • the wall of the bag interior 70 of the filter bag 5 contained a filter membrane 50.
  • a filter membrane 50 In a further embodiment of the present invention Fig. 4 . 5 and 6
  • two or more filter membranes 50, 51 can be used to form the bag inner spaces 70, 71 of the filter bag 5.
  • the bag openings of the individual filter membranes 50, 51 are connected to one another, so that, viewed from the outside, a filter bag 5 with a bag opening 6 results, which contains nested individual bags made of filter membranes 50, 51.
  • the filter bag 5 then contains a plurality of individual bags with a common bag opening 6.
  • the process air 12 flows in such a multi-layer filter bag 5 through the common bag opening 6 in the innermost bag interior 70, flows through the first filter membrane 50, enters the second bag interior 71, flows through the second filter membrane 51, etc.
  • the filtering effect of the filter bag 5 can be improved, so that when a flow through the filter bag 5 less Wäscheflusen 17 remain in the process air 12.
  • the filter membranes 50, 51 in the direction of the flow of the process air 12 with decreasing mesh sizes, ie the innermost filter membrane 50 has a larger mesh size than the second filter membrane 51, etc.
  • Such an arrangement on the one hand achieves a good filter effect. small mesh sizes are possible in filter membrane 51 as discussed above, but not with rapid "clogging" of the inner filter membrane 50 to be expected by Wäscheflusen 17, since here larger mesh sizes can be used (prefiltering).
  • the bag interior 70, 71 in the direction of the flow of the process air 12 with increasing volumes, i. the innermost bag interior 70 has a smaller volume than the second bag interior 71, etc.
  • controller 99 contains e.g. a microprocessor programmed to perform the steps described above automatically.
  • a controller 99 contains e.g. a microprocessor programmed to perform the steps described above automatically.
  • the tumble dryer is "designed" to perform certain steps, it is to be understood that the control of the device is structured to perform the steps automatically.
