Definitions

  • the invention relates to a method for drying laundry in a tumble dryer containing a laundry drum, wherein heated drying air is introduced into the drum, flows through the drum and is taken out of the drum after absorbing moisture.
  • the invention further relates to an arrangement for performing this method.
  • the invention is based on the object of specifying a method of the type mentioned at the outset, which is improved over known methods. Furthermore, an arrangement for carrying out this method is to be created be, which is simpler and cheaper in comparison to known arrangements and allows better use of energy.
  • An improved method of the type mentioned is achieved in that the drying air is fed into the drum in the front area and out of the drum in the front area.
  • This design enables the drying air to be guided easily on one and the same end face, namely in the front area of the clothes dryer. This eliminates the need for complicated air routing, in which the drying air is introduced into the rear wall, flows through the drum and exits at the front.
  • Such a method enables simple drum construction, e.g. made of plastic, also no perforation in the rear wall of the drum is required. This results in a considerable saving in costs since stainless steel is no longer required to manufacture the drum.
  • the drying air in the area outside a filling opening arranged on the front is led into the drum and out of the drum.
  • This design enables simple door design, since the door and therefore the filling area no longer perform air routing functions.
  • the drying air is preferably introduced into the drum in the area above the filling opening and out of the drum in the area below the filling opening. This design enables a simple sieve arrangement in the area below the filling opening.
  • the above-mentioned method for drying laundry can also be improved in that the drying air, for example via a perforated rear wall in the drum is introduced, flows through the drum and leaves the drum again in the area outside the front filling opening.
  • the drying air does not leave the drum in the area of the door, but also in the area outside the filling opening, so that here too there is the advantage of a simple door design, since the door and filling area do not perform any air routing functions.
  • the drying air is preferably also led out of the drum in the area below the filling opening.
  • An arrangement for carrying out the above-mentioned methods is characterized in that the drum is formed by a cup-shaped container which is open at the front and is rotatably mounted on a horizontal axis, and by a stationary, ring-shaped front part with a filling opening which can be closed by a door .
  • This pot-shaped container can be made of plastic, for example, and has a simple structure, since no perforation is required on the rear side for the entry of drying air if the type with front supply and discharge of the drying air is selected.
  • the annular front part is preferably provided above the fill opening with inlet openings and below the fill opening with outlet openings for the drying air. This design enables an advantageous arrangement of the heating device above the drum. Due to the heating device arranged at the top, the rising warm air is also used for the drying process. Furthermore, the heating device arranged above the filling opening results in simple thermal protection and the advantage that the heating device in this construction is positioned relatively far from the laundry lying in the dryer.
  • the drum is cylindrical or conical in shape and has drivers which are directed from front to rear. This enables an improved rearrangement of laundry from the back to the front and the stiffness of the drum can be improved.
  • a fluff filter is provided in the area of the outlet openings below the filling opening.
  • This fluff filter can e.g. be designed as a plug-in screen and detachably arranged.
  • the door is provided with a fluff filter opposite the outlet openings, which projects into an air duct when the door is closed and lies in front of the outlet openings.
  • This sieve which is permanently installed in the door, is freely accessible after opening the door and can be easily cleaned.
  • the drum 1 has a housing 10 with a drum 12 rotatably mounted in the housing via a horizontal axis 11.
  • the drum 12 is designed as a pot-shaped container which is open on one side and is rotatably mounted in a bearing 13 via its rear wall 12a.
  • the open front of the drum is closed by a fixed, annular front part 14 and contains a fill opening 15 which can be closed by a door 16.
  • a fan 18 driven by a motor 17 is arranged below the drum 12.
  • the drying air 19 is heated by a heating device 20, which is arranged in a chamber 20a above the drum 12 within the housing 10.
  • the heated drying air 19 is sucked into the drum 12 by the fan 18 via inlet openings 21 in the annular front part 14 above the filling opening 15, flows through the drum approximately in a semicircular arc and leaves the drum 12 via outlet openings 22 in the annular front part 14 below the filling opening 15
  • the drying air 19 laden with moisture is led to the outside.
  • the drying air 19 laden with moisture is guided to a heat exchanger (not shown), on which liquid is separated out, and then returns to the drying cycle.
  • a lint filter is designated, which is arranged in this type in the region of the outlet openings 22 and is designed as a plug-in sieve and removed for cleaning purposes with the door 16 open can be.
  • the rear wall 12a of the drum 12 is not perforated.
  • With 24 laundry deflectors are designated.
  • the type according to FIGS. 2 and 3 differs from the type according to FIG. 1 only by the arrangement of the fluff filter 25, which is arranged on the swing-out door 16 in this type.
  • the fluff filter 25 projects into an air duct 26 and lies in front of the outlet openings 22, so that the dry air flow 19 is passed through the fluff filter 25 into the air duct 26.
  • the fluff filter 25 With the door open according to FIG. 3, the fluff filter 25 is pivoted out of the air duct 26 and can be cleaned in a simple manner.
  • the design according to FIGS. 2 and 3 corresponds to the design according to FIG. 1.
  • the dry air 19 ' is guided through the perforated rear wall 12b into the drum 12, flows through the drum and leaves it via the outlet openings 22 below the filler opening 15.
  • the heater 20 in the flow channel 27 is between the Fan 18 and the perforated rear wall 12b arranged.
