Definitions

  • the invention relates to a clothes dryer with a roller bearing, in which the Laundry drum is additionally guided in the region of its feed opening by means of rollers, wherein the rollers support the laundry drum on the drum basket drum and the Bearing axes of the rollers arranged at one in the region of the feed opening fixed support member are rotatably mounted.
  • Such a tumble dryer is known from DE 196 15 822 C1.
  • the established Support part encloses the feed opening of the laundry drum and is used as a plastic molded part formed, which is arranged fixed to the housing walls of the clothes dryer.
  • the plastic molding carries the storage for the laundry drum and is as a part of the Process air ducts formed.
  • this plastic molding for receiving in the Process air duct section to be used lint filter and designed to hinge the door.
  • the Casters for supporting the laundry drum shell outside the sphere of influence with Fluff loaded process air flow arranged.
  • the casters are, facing the Loading opening seen arranged on the back of the stationary housing part.
  • the fixed support member for the Storage of the rollers is not designed as a process air duct section.
  • the usually large-volume laundry drums require a more sustainable support of the laundry drum in the area of the loading opening.
  • the known tumble dryer Miele T 6251 is the Support member for the storage of rollers designed as a partition.
  • the partition encloses the laundry drum in the area of the front loading opening and forms together with the housing walls, the process air guide portion of the front air duct.
  • This Front air duct is a large surface filter arranged below the laundry drum.
  • the Casters are seen on the loading drum with respect to the loading opening of the laundry drum Front of the fixed support member or the partition arranged.
  • the rollers support the laundry drum on the laundry drum circumference in the front of the Laundry drum off.
  • the frontal laundry drum wall, in which the feed opening is arranged has a perforated annular region over which the process air flow out of the laundry drum in the direction of large surface filter.
  • the rollers are at This described training process air flow in the sphere of influence of the Process air flow arranged.
  • a disadvantage of this arrangement is that small items of laundry such as apron ribbons, threads etc. due to the guided over the front Wäschetrommellochung process air flow can pass through the holes in the area of the running surfaces of the rollers.
  • the Laundry items can wrap around the axles of the casters, resulting in increased noise and leads to premature wear of the rollers.
  • Another disadvantage is that the in the process air flow entrained lint through the front drum hole in the area of Running surfaces and the storage of rollers can get. The deposit of lint on treads and bearings leads to increased noise and premature wear the caster assembly.
  • the invention thus raises the problem of the roller arrangement of a tumble dryer To protect against damage by washing parts and the deposition of lint from the To avoid process air flow at the bearing of the roller.
  • the achievable with the present invention consist in particular that in the range of At least one roller arrangement means are provided which the gap area between cover rotating roller and fixed partition approximately gap-free or fill out.
  • a Guard provided, which is arranged concentrically to the bearing axis and the Fills gap area.
  • a further development of this embodiment is the cup-shaped design of the Protective disc, whereby the axially directed running surface of the roller in the area of Between space or in the gap area cup-shaped is enclosed. The protective screen is against twisting with a corresponding fuse e.g. secured a locking pin.
  • a further advantageous embodiment of the invention provides, the means as at the partition form arranged approach that covers the gap area.
  • the approach can be the axial Cover the directional running surface of the roller in the gap area.
  • the approach can be the roller enclose annular. It is possible, even a portion of the scope of To enclose roller.
  • a further advantageous embodiment is provided in the Near the vulnerable areas on the rollers Small diameter holes in the to arrange fixed partition, via which an air flow in the negative pressure area is sucked and entrains the lint.
  • the outlet opening of a To arrange air supply line in the vicinity of the roller assembly. The air inlet opening of this Air supply line is outside the process air duct.
  • the tumble dryer is formed with a housing (1).
  • the laundry drum (2) in a known manner via a not shown rear bearing and a front side, described in more detail below roller bearings, rotatably mounted.
  • the front and rear storages of the laundry drum (2) are received by a support frame (3) shown schematically in Figure 2.
  • this support frame (3) On the Front side, this support frame (3) as a support member (3 ') formed partition (4) for the Support the rollers (5).
  • the partition (4) encloses the laundry drum (2) in Area of the front loading opening (6).
  • This partition (4) forms together with the housing walls (7) the process air guide portion (8) of the front air duct.
  • This front air duct is a large surface filter (9) below the laundry drum (2) arranged.
  • the rollers (5) are facing the feed opening (6) of the Laundry drum (2) seen on the front of the fixed support member (3 ') and the Partition (4) arranged.
  • the rollers (5) support the laundry drum (2) on Laundry drum circumference (2 ') in the front region of the laundry drum (2) on one Raceway surface (10) from.
  • the front-side laundry drum wall (11), in which the Charging opening (6) is arranged, has a perforated annular region (12), via which the process air flow from the laundry drum (2) in the direction of large area filter (9) to be led.
  • the rollers (5) are in this described embodiment of the Process air duct arranged in the sphere of influence of the process air flow.
  • FIGS. 1, 2, 3 and 4 This area is shown in FIGS. 1, 2, 3 and 4 as a gap area or catchment area (14).
  • Figure 3 is the endangered Cleavage region or catchment area (14) shown on an enlarged scale as a detail A.
  • Figure 4 shows a first embodiment of the invention wherein the gap between fixed support member (3 ') or partition (4) and rotating roller side surface (17) or the gap area / catchment area (14) at least approximately gap-free through a protective pane (16) is completed.
  • the protective disk (16) is arranged concentrically to the bearing axis (15). at In the exemplary embodiment shown here, the protective pane (16) covers part of the Running surface (5 ') of the roller (5) in the gap region (14).
  • the protective disk (16) is shaped in such a way that they cup-shaped a portion of the tread (5 ') in the critical catchment area (14) encloses.
  • This version is particularly suitable when the tumble dryer no Laundry drum (2) enclosing partition (4) as a supporting part (3 ') for the rollers (5) but has a cross member, not shown for receiving the rollers (5).
  • the Protective disk (16) is secured against rotation by means of e.g. a locking pin (18) against Secured turning.
  • Figure 5 shows another embodiment of the invention wherein the gap between fixed support member (3 ') or partition (4) and rotating roller side surface (17) or the gap area / catchment area (14) at least approximately gap-free through a projection (19) is covered.
  • the projection (19) is formed on the support part (3 ') or the partition wall (4) or attached by a screw etc.
  • the approach is designed to be a Section of the tread (5 ') in the critical catchment area (14) surrounds annular.
  • FIG. 6 shows an exemplary embodiment with a roller arrangement in which, in the vicinity of the at least one in the dividing wall (4) arranged ventilation opening (20) is provided.
  • the ventilation opening (20) is near the Feed area (14) or the contact point of the roller surface (5 ') of the roller (5) and Raceway surface (10) of the laundry drum (2) arranged.
  • As a ventilation opening (20) preferably two holes with a small diameter in the range of 3 to 6 mm intended. About this air supply fresh air is sucked into the negative pressure area, resulting in eliminating the lint deposits leads.
  • the fixed support member in the range of at least one roller arrangement an outlet opening (nozzle) of an air supply line assigned.
  • the suction port of the air supply line is outside the negative pressure range the front air duct.
