Definitions

  • This invention refers to a rotary drum drying machine, in particular for drying washing.
  • the drum containing the material to be dried is supported by a pivot protruding coaxially from the rear wall and supported cantilevered by a bearing fitted on the supporting structure of the machine.
  • An electric motor causes the drum to rotate, generally by means of a belt which winds peripherally around a large pulley secured coaxially to the drum, thus also creating a suitable reduction ratio between the motor and the drum.
  • the structure of the drum and the coupling between the latter and the pivot must be made of sturdy material, which increases the cost and the weight of the drum, resulting in a consequent increase in stress on the pivot.
  • a drying machine in particular for drying washing, of the type comprising a substantially horizontal drum containing the material to be dried, which is made to rotate by an electric motor, characterized by the fact that the drum is supported in the machine by resting on a plurality of rolls with axes parallel to the axis of the drum, at least one of which is made to rotate by the motor through motion transmission means.
  • a first embodiment of a drying machine in particular for drying washing, generically indicated by reference 10 in figure 1, comprises according to the invention an external structure 11 containing a rotary drum 12 for holding the material to be dried which is placed in it through a window 19.
  • the drum 12 is supported by simply resting on rolls 13 which rotate on supports 18 secured to the structure 11, disposed in pairs along two generatrices of the drum in a symmetrical position with respect to a vertical plane crossing the axis of rotation of the drum itself.
  • a pair of rolls 13 is keyed onto a common spindle 14 carrying a pulley 15 connected, by means of a belt drive 16, to an electric motor 17.
  • the drying machine obviously comprises a set of devices of known technique, such as heating elements, moisture condensers, timers, thermostats, etc., which are easily imaginable by any expert technician and will therefore be neither further described nor shown, since they do not form part of this invention.
  • FIGS 3 and 4 show a second possible embodiment, according to the invention, of a drying machine, in particular for drying washing, generically indicated by reference 110 and comprising within a structure 111 a rotary drum 112, containing the material to be dried which is placed in it through a window 119.
  • the drum 112 is supported by simply resting posteriorly on idle rolls 113 (only one of which is shown in figure 4 since the other is identical and symmetrically disposed with respect to the drum 112) and anteriorly on rolls 114 driven by means of a belt 116 connected between a pulley 120 integral with one of the rolls 114 and an electric motor 117, and a second belt 121 disposed between the two rolls 114.
  • the rolls 113 and the rolls 114 are rotatingly mounted on supports 118.
  • the belt 121 is in contact with the outer edge of the drum disposed between the rolls 114, thereby permitting a satisfactory transfer of torque by friction.
  • the drum 112 is made to rotate in order to carry out the drying operations.
  • drum guide means are provided in order to keep the drums correctly positioned on their respective supporting rolls.
  • Said means can be advantageously incorporated in the supporting rolls.
  • the drum 12 may comprise, along the seam between the peripheral wall 20 and the bases 21, a raised rib 22 (which may advantageously be the rib formed by the folding and seaming operation to join the base to the peripheral wall) which rests in a complementary groove 23 on the outer edge of the rolls 13 (or 113) supporting the drum, thus enabling the drum to maintain its correct axial position on the rolls.
  • a raised rib 22 which may advantageously be the rib formed by the folding and seaming operation to join the base to the peripheral wall
  • FIG. 6 A second example of guide means using the supporting rolls is shown in figure 6.
  • the axial guide for rotation of the drum is provided by trapezoidal grooves 24 made circumferentially on the surface of the drum 12 (or 112) to receive the complementally shaped outer edge of the rolls 13 (or 113).
  • Wheels 26, 126 placed in position around the drum, may also be provided to counteract, together with the supporting rolls, any sideways movements of the rotating drum and thus prevent possible shifting of the drum inside the structure of the machine, especially during the initial phases of rotation.
  • the drive belt between the motor and the pulley also has a constantly high degree of adherence without the need for special devices, since there is very little or no difference between its winding angles.
  • the drying machine is quick and inexpensive to assemble due to the fact that the drum only has to be rested on the guiding and driving rolls.
  • transmission of the movement between the drive shaft and the rolls 114 can be obtained with a single belt in place of the belts 116 and 121.
  • the aperture for loading the drum can also be made on top instead of in the front as shown in the drawings, as is easily imaginable by any expert technician.
