  • the cup-shaped filter body has an outer filter surface in the manner of an open bag by a support structure is held.
  • the closed lower end of the bag is arched into the inside of the pot arranged and thus forms the inner filter surface arranged inside the filter body. This increases the effective filter area.
  • the support structure for the filter bag is designed to be resilient and expands under the influence of the suction air flow. at If the air flow ceases to exist, the supporting frame returns to its original shape. Through this Training, the dust particles deposited on the filter surface are shaken off and in Dust room collected.
  • This filter device is for manual cleaning of the filter surface not suitable for the filter bag due to the spring-elastic support structure.
  • a filter device for a clothes dryer in which a cup-shaped filter insert is inserted into a receiving body and in Intake air flow for the dry air is arranged.
  • the intake air for the dry air flow passed through a filter device to this air for a hygienic drying process rid of dust particles and the like.
  • the receiving body is cylindrical and has on its periphery suction openings for one directed into the filter interior Air flow on.
  • the filter insert can be removed from the holder body for cleaning become.
  • Such an intake air filter is for filtering out the lint from the process air flow not suitable.
  • the invention thus addresses the problem of a filter device suitable for manual cleaning for a tumble dryer with a large effective filter area for an optimal To design lint removal from the process air flow.
  • the filter device with a dimensionally stable support structure for an outer and one arranged therein inner filter body is formed.
  • the filter elements are arranged one inside the other Air flow through the special design of the support structure in parallel and not in succession flows through.
  • This configuration makes the effective filter area with a small installation space the filter device enlarged.
  • the filter bodies are together in the area of their bottom surfaces connected and removed together for cleaning. Behind the filter device the impeller is arranged, which is easy after removing the filter device is accessible and can also be cleaned.
  • a particular advantage is the divisible Design of the filter device.
  • the inner and outer filter bodies are made up together removed from the device and can be separated for cleaning. This is in the area of Bottom surfaces of the two filter bodies have a connection arrangement which connects the two filter bodies interlocked, provided.
  • FIG. 1 shows the arrangement of the filter device (1) according to the invention in shown a dryer.
  • the tumble dryer is rotatable in a housing (2) stored laundry drum (3), the loading opening (4) of the laundry drum (3) closing door (5), a blower (6) for generating a process air flow through the Washing drum (3) and a heating device (7).
  • the process air flow is via a Process air duct section (8) with the heating device (7) to the drum inlet (9) through which Laundry drum (3) and via a process air duct section (10) from the drum outlet (11) led to the blower (6).
  • the lint filter device (1) is the drum outlet (11) Process air downstream and preferably in the lower part of the process air duct section (10), which is designed as a filter housing (12).
  • the control of the process air flow through the clothes dryer is shown with arrows.
  • the lint filter device (1) is accessible from the front of the housing (2) and is accessible from the outside via a filter opening (13) inserted into the process air duct section (10).
  • the filter device (1) is this first embodiment behind a filter opening (13) in the process air duct section (10) tightly closing maintenance flap (14) in the front of the housing (2) and has a handle (15).
  • the design of this filter device (1) is shown in FIG. 2.
  • FIG 2 shows the filter device (1) to be arranged behind a maintenance flap (14) as Detail.
  • the filter device (1) consists of two columnar filter bodies (16, 17).
  • the filter bodies (16, 17) each consist of a dimensionally stable columnar Support structure that support the filter surfaces (18).
  • the inner filter body (17) is inside the outer filter body (16) arranged.
  • the filter bodies (16, 17) are in the area of their bottom surfaces connected with each other.
  • the filter body (16, 17) can be unsolvable or via a releasable connection to be connected.
  • the supporting structures of the two filter bodies (16, 17) form a seen in the air flow direction in the embodiment shown annular closed bottom surface (19).
  • the webs (20) end on the upper molded part on the upstream side Edge (21).
  • This edge (21) is a sealing edge to the filter housing (12) for the filter device (1, see also Figure 1).
  • the air flow becomes due to the formation of the sealing edge passed into the pot interior of the filter device (1).
  • From the inner ring the ring-shaped trained bottom surface (19) extends the inner filter body (17).
  • the In the embodiment shown, webs (22) end on the bottom surface (19) opposite side in a cover surface (23).
  • the top surface can be closed be trained.
  • the handle (15) is arranged, over which the entire Filter device (1) unlocked and can be removed.
  • the top surface (23) can also be used a further screen surface (not shown).
  • the inner filter body (17) is at the illustrated embodiment compared to the outer filter body (16) in the area the top surface (23) is elongated in the axial direction.
  • the top surface (23) is in the installed state in this variant behind the filter opening (13) in the process air duct (10) sealing final maintenance flap (14).
  • the inner and outer filter body (16, 17) are preferably releasably connected to one another so that the filter surfaces (18) are light are to be cleaned by hand.
  • the bottom surface is with a handle (24) trained.
  • FIG 3 shows the filter device according to another embodiment with an integrated Filter cover (25), which seals the filter opening (13).
