Definitions

  • the invention relates to a bag for filtering lint from the process air flow of a tumble dryer with a rotatably mounted in a housing drum, wherein the process air flow inter alia via an interposed between the drum and a heat exchanger as a flow channel air duct, wherein the bag is used on the air duct and by means of a trained as a closed angle profile adapter plate on the air guide can be attached.
  • the filter device may consist of one or more filter bodies.
  • a filter body has a support frame on which an example quarder-shaped filter frame is attached.
  • the filter frame carries as filter surface a filter tube.
  • a filter for arrangement in an air duct known.
  • the filter forms a space for collecting fluff by firmly connecting a front and a rear frame with each other.
  • a plurality of suction openings for introducing the process air are formed.
  • a mesh screen is designed as an outlet for the process air.
  • the rear frame of the filter and the rear portion is formed with a sealing unit.
  • a tumble dryer with a disposable lint filtering known In this known device, the circulating through the laundry drum air flow is filtered by means of a bag.
  • the filter device in the exhaust air stream of the air cycle of the laundry drum Wäscheflusen be entrained, wherein the retention of these Wäscheflusen the filter device is used, which is arranged in the exhaust duct of the tumble dryer.
  • the lint filter device in this case comprises a filter bag with a bag opening and a bag interior, wherein the filter bag according to the prior art is arranged in the door of the clothes dryer.
  • a further lint filter device for a household laundry dryer wherein in this embodiment, the lint filter device is arranged to trap entrained in the process air Wäscheflusen in the exhaust duct.
  • the lint filter device here is likewise designed as a removable bag.
  • the bag essentially comprises a holding frame and a filter bag or a filter bag fastened therein.
  • the support frame may be formed as a closed frame or as a split frame.
  • the filter bag is used here in the housing-side exhaust duct.
  • the invention thus raises the problem of further developing a tumble dryer and here in particular a lint filter stored in the flow channel which on the one hand overcomes the described disadvantages, in particular the problem being solved that the bag incorporated in the flow channel has a much better accessibility, wherein to be avoided when removing the bag from the holder that particular lint get into the flow channel or in the air duct, and wherein a better integration of the bag should be provided.
  • a secure and sealing integration and a stable position of the bag to the air duct should be created.
  • the advantages achieved with the invention consist in the fact that a secure and stable position of the bag opening is given to the air duct by the integration of the bag by means of an adapter plate.
  • the adapter plate engages in the bag to avoid leaching in the inlet area.
  • the bevels on the sides of the adapter plate allow the customer a much better positioning of the bag.
  • Round outer contours and the shape of the elongated hole favor the molding of a sealing lip, wherein the inwardly facing round tapered contour favors the flow especially the air flow.
  • a free vibration in the height direction is also possible in the injection molding process, to a lower distortion of the component than in a non-conical inlet.
  • the seals can be designed as circulating in various forms.
  • the cambered design of the adapter plate has a particularly advantageous effect, and this is very sensible because, in the case of a seal which has to be pressed with a relatively high force, the sufficient tensioning of the seal is ensured. This force would now be sufficient to press the adapter plate over the entire surface. Due to the cambered shape and a high contact pressure one is independent of manufacturing tolerances. It is ergonomically better to provide a thin sealing lip, which requires a much lower spring stiffness and which would also require a lower contact force in order to achieve the necessary deformation. To ensure a process-reliable sealing effect of the cover plate, it is necessary that the lower edge of the seal has a high flatness.
  • the bag is attached to the air duct by means of an adapter plate.
  • the adapter plate itself consists of a closed angle profile, which has a substantially horizontally oriented leg for resting on the air duct.
  • the horizontally oriented leg on a running under a slope end portion which carries an applicable to the air guide seal.
  • the seal may in this case advantageously consist of a simple lip seal, a double lip seal or a block seal.
  • the adapter plate has a slot-like or elliptical shape, with the substantially vertically-oriented leg having a leg orientation with a slight incline so as to create a funnel shape.
  • the bag can be welded or glued with its opening edge on the adapter plate.
  • the bag is releasably attachable to the adapter plate. As a result, manufacturing costs can be saved. It can then either be provided as an integral part of the clothes dryer an adapter plate or be enclosed with a container which contains, for example, four or five bags, an adapter plate.
  • the frame of the adapter plate is arched, wherein due to this curvature in particular of the horizontally oriented Thigh in the inserted state, the adapter plate rests under tension on the air duct, which in this case causes a sealing contact with the air flow for the bag.
  • the adapter plate as a profile shape preferably has an angular shape.
  • the angle shape has a substantially horizontally oriented leg for resting on the air guide, wherein the leg oriented substantially vertically is intended for securing the bag.
  • the horizontally oriented leg in this case has a running under a slope end.
  • the end region of the limb running under a slope rests against the air guide under an arranged circumferential seal.
  • the seal may in particular consist of a flat lip seal or a double lip seal or a block seal, which is in this case peripherally attached to the adapter plate.
  • the use of a flat lip seal would have the advantage that it already achieved the required sealing effect with a lower force, which would be achieved in the double lip seal only with a relatively high force. The latter would also apply to a block seal.
  • the vertically oriented leg is formed under a curvature or rounding on the horizontal leg, wherein the leg alignment has a slight conicity. Due to this design, a flow-favored inlet at the edge of the bag is created, and this also means that the customer or the operator here has a secure handle for the use of the bag.
  • the adapter plate has a cambered shape. This can be formed either convex or concave, which contributes in particular to increase the tightness. Because in the cambered design, the adapter plate is inserted under a clamping position on the air duct, the force is applied to the cover to be used or the cover. The cover member presses in the inserted state, the circumferential seal thus to the air flow, so that it rests against the air duct under a press fit.
  • the frame of the cover plate is pressed in the inserted state of a cover under tension in the sealing position.
  • the cover comprises a trained as a thrust laundry barrier, which forms the entrance of the flow channel.
  • the invention also relates in the same way to a tumble dryer with a bag which is designed according to the described features.
  • FIG. 1 shows in particular in the exploded view of an air guide 1 with a bag 2 for a clothes dryer, not shown, which comprises a housing in which a drum is rotatably mounted.
  • the tumble dryer in this case has a device for generating a process air stream, which flows via an intermediate between the drum and a heat exchanger as a flow channel 3 air duct 1, wherein in the air guide 1 lint filtering by means of the bag 2 shown.
  • the flow channel may be an integral part of the air duct, but it may also be at least partially designed as a usable insert. It is suitable at its upper edge for receiving an adapter plate 4 described below.
  • the bag 2 is integrated by means of the adapter plate 4 to the flow channel 3 of the air guide 1.
  • the bag 2 is welded or glued with its opening edge 5 on the adapter plate 4.
  • the adapter plate 4 comprises a frame which causes a sealing contact with the air guide 1 for the bag 2, this situation in particular in the FIGS. 5 and 6 but also in the FIG. 7 is shown in the exposed representation.
  • the adapter plate 4 has a profile shape, preferably an angular shape.
  • the angle form here comprises a substantially horizontally oriented leg 6 for engagement with the air guide 1, wherein the substantially vertically oriented leg 7 is intended to define the bag edge.
  • the integration of the bag 2 is here in particular in the FIGS. 5 and 6 to recognize.
  • the horizontally oriented leg 6 an under a slope 8 extending end region. It lies, as in particular from the FIG. 10 can be seen, under the slope 8 of the leg 6, a circumferential seal 9, which applies in the inserted state of the bag 2 with the adapter plate 4 to the air guide, shown in the FIG. 7 , according to a particularly advantageous embodiment of the seal 9, shown in the FIG. 10 , this can consist of a simple lip seal a, wherein a double lip seal b can be used, which is designed as a downwardly open parabola. It is also conceivable here to design the seal 9 as a block seal c.
  • the seal can also be realized in an embodiment not shown in the drawings in that the bag material 2.1 preferably protrudes into the region of the horizontally oriented leg 6 and then rests against the flow channel 3.
  • the bag material 2.1 is compressed during insertion of the adapter plate due to the shape of adapter plate 4 and air guide adapter 3 and can thereby act as a seal.
  • This embodiment has the advantage that no additional sealing material is needed. As a result, a seal in this form can be produced very inexpensively.
  • one of the seals a, b or c or another suitable seal can be arranged on the flow channel 3. This has the advantage that the seal is not disposed of with each bag together, but can remain in the device. The manufacturing costs of the adapter plate 4 are cheaper in this embodiment.
  • the vertically oriented leg 7 is formed under a curvature 10 on the horizontal leg 6, wherein the leg orientation has a slight taper 11. Due to this design it is achieved that in particular the flow inlet in the region of the opening edge of the bag 2 is designed to be low here.
  • the FIG. 10 also shows the attachment of the bag material 2.1 and a receiving groove 9.1 on the horizontal leg 6, in which the seal 9 can be attached.
  • the cambered curvature in particular in the FIG. 9 is indicated.
  • the domed shape can be either concave or convex. Due to this design is achieved in particular that in the inserted state of the adapter plate 4, the Seal 9 is held at the air guide 1 under a certain tension.
  • the frame of the adapter plate 4 in the inserted state as shown in the FIG. 2 and 3 is shown by a cover 12 can be pressed under tension in the sealing position, as this particular in the FIGS. 5 and 6 but also in the FIG. 7 will be shown.
  • the cover member 12 in this case has a lower edge region 12.1, which is in particular wedge-shaped.
  • the wedge shape favors this particular one hand, the piecing of the cover 12 on the attached cover plate 4 on the air guide 1, because thereby the threading of the cover is favored.
  • the contact pressure with the penetration depth of the edge region 12.1 on the adapter plate 4 is increased by the wedge shape, which favors the sealing effect of the bearing seal 9.
  • the cover 12 is formed as a thrust, which serves here as a laundry barrier to the air duct 1 due to its sieve-like top surface.
