Definitions

  • the invention relates to a household appliance, for. B. on a clothes dryer, with a housing and a rotatably mounted in the housing drum, the inner wall is provided with drivers.
  • the invention has for its object to increase the drum volume in a simple manner.
  • the inner drum wall is provided with a large number of flat, gently rounded drivers which are arranged evenly distributed over the inner circumference of the drum. This means that the drum volume can also be fully utilized in the area of the drivers, since the laundry clings to the flat, gently rounded drivers without any cavities. Due to the large number of drivers according to the invention, a reliable take-along of the laundry is ensured when the laundry drum rotates.
  • the construction according to the invention ensures that laundry transfer can take place without inhibition by the driver elements even with a high load.
  • the design according to the invention enables optimal use of the drum volume, since cavities in the laundry in the area of the drivers are avoided, especially at high loads, through which the heated dry air flow reaches the outlet side, sometimes unused. Overall, this results in an improvement in the evenness of the drying process and an energy saving.
  • the drivers can be manufactured as special components and attached to the inner circumference of the drum casing. In a further embodiment of the invention, it is also possible to mold the drivers into the drum jacket.
  • a preferred embodiment is that about six to twelve drivers are arranged on the inner circumference of the drum shell of a conventional dryer. Particularly good values have been obtained with such a design.
  • the drum volume can be further increased by the depth of the constriction being at least as great as that the surface of the drive belt is flush with the outer surface of the Drum casing completes.
  • a maximum large drum outer diameter can be selected for a given size of the housing.
  • a corresponding distance between the drum and the housing is required because of the drive belt projecting beyond the outer surface of the drum, so that a space resulting therefrom is lost as a receiving space for the laundry drum.
  • an advantageous embodiment of the invention is that the laundry drivers are formed in the intersection with the constriction so that a continuous tread is formed for the drive belt.
  • This design ensures that the drive belt does not have to run over gaps in the area of the drivers, but instead finds a continuous, uniform running surface. This avoids a so-called "beating" of the drive belt and thus a possible source of noise.
  • the aforementioned special shaping of the drivers in the mentioned intersection area means that the drivers are divided in the area of the Constriction, which also increases the volume of the laundry drum. As has been shown, such an interruption of the drivers running in the axial direction of the drum does not change the laundry movement. During the drying process, at most one small piece of laundry, for example a stocking, could slip through.
  • the laundry drivers each have at least one further interruption outside of the intersection area with the constriction, as a result of which there is hardly any influence on the laundry movement, but a further increase in the drum volume can be achieved.
  • a drum for a washing machine has become known in which the laundry drivers are not arranged continuously in the longitudinal direction, but are interrupted and, starting from approximately the middle to the front edge, are arranged in a gap. It is also not a question of increasing the drum volume, but of giving the laundry a back and forth movement within the drum in addition to the lifting caused by the drivers, in order to counteract the formation of lumps.
  • the laundry drum 10 can be rotated about an axis 11 and has a jacket 12 and two end faces 13 and 14, respectively.
  • 15 molded laundry drivers are indicated, which are arranged evenly distributed on the inner circumference of the laundry drum 10.
  • the laundry drum is each provided with a constriction 16 which forms a running surface 17 for receiving a drive belt 18.
  • the radial height 19 of the drivers 15 is approximately three times the radial height 20 of the constriction 16.
  • the laundry drivers 15 are each interrupted once in the intersection area with the constriction 16. This results in the possibility of forming a running or support surface 17 for the drive belt 18 which is also continuous in the intersection area.
  • the laundry drivers 15 are each divided into two sections 15a and 15b.
  • the long sections 15b according to FIG. 2 are each interrupted in three further sections 15c, d and e. Because the originally continuous laundry drivers are interrupted in sections 15a to e, there is a further increase in the drum volume. This interruption has practically no effect on the carrying of the laundry parts when turning.
  • the sections of two adjacent laundry drivers can each be set to a gap, thereby reducing the risk of small laundry items slipping through.
  • the laundry drum 21 according to FIGS. 4 and 5 has a large number (here twelve) of drivers 23 arranged uniformly distributed on the inside of the drum jacket 22.
  • the drivers are flat and gently rounded.
  • a constriction for a drive belt is not shown here, but of course, as shown in FIG. 1, also possible in order to also be able to take advantage of the larger drum.
