Definitions

  • the present invention relates to a horizontal axis washer/dryer comprising a plastic tub.
  • a bearing sleeve embedded at the centre of the back wall of a tub is exposed to pressures produced by the spinning of the drum and of the shaft during wash and spin dry cycles.
  • the movements of a bearing sleeve, which provides bearing for the shaft are blocked by ribs extending along the exterior wall thereof.
  • a bearing sleeve may move and break partly or totally away from the tub.
  • EP1798016 describes a bearing sleeve that comprises ribs on both ends, extending in parallel with the shaft axis.
  • the aim of the present invention is the realization of a washer/dryer comprising a bearing sleeve which is provided with improved resistance and which is integrated with a plastic tub.
  • the washer/dryer of the present invention comprises one or more recesses formed on the side walls of the ribs positioned over a bearing sleeve.
  • these recesses provide a more abundant amount of plastic substance to contact the surface while filling the area around a bearing sleeve, said bearing sleeve being disposed at the centre of a mould, and enable a more efficient connection between a bearing sleeve and a plastic tub at the end of the process.
  • the movement of the bearing sleeve that bears the shaft which is spinning at the same speed as the drum, is reduced to a minimum with respect to the tub and the strength of the bearing sleeve is increased.
  • the recesses are positioned along the side walls of the ribs.
  • the recesses are positioned on the side walls of the ribs at regular intervals.
  • each recess is supplied in front with a groove that intersects said recess.
  • the part of the bearing sleeve nearest to the exterior of the tub is inclined towards the axis of the shaft.
  • the heights of the ribs positioned in this part increase gradually towards the exterior of the tub.
  • the bearing sleeve is thus provided with increased resistance.
  • Figure 1 - is a cutaway view of a washer/dryer.
  • Figure 2 - is a cutaway view of a tub.
  • Figure 3 - is a perspective view of a bearing sleeve.
  • Figure 4 - is a cutaway view of one other tub.
  • Figure 5 - is a perspective view of a bearing sleeve in one other embodiment of the invention.
  • the washer/dryer (1) comprises a plastic tub (2), a drum (3) which is disposed inside the tub (2) coaxially with the tub (2) and into which laundry is loaded, a motor which enables the drum (3) to spin around its own axis, a shaft (4) which transmits the motor movements to the drum (3), and a bearing sleeve (5) which is situated at the centre of the back wall of the tub (2) and which provides bearing for the shaft (4) ( Figure 1).
  • the bearing sleeve (5) comprises more than one rib (6) on the exterior surface, positioned at regular intervals and practically in parallel with the axis (A) of the shaft (4) and one or more recesses (7) provided on the side walls of the ribs (6) ( Figure 2, Figure 3, Figure 4, and Figure 5).
  • the bearing sleeve (5) comprises one continuous recess (7) produced along the side walls of the ribs (6) ( Figure 2 and Figure 3).
  • the bearing sleeve (5) comprises several recesses (7) produced at regular intervals on the side walls of the ribs (6).
  • the cross section of the side walls of the ribs (6) with the bearing sleeve (5) may have different geometrical forms, may be for example in the form of an arc fragment.
  • the bearing sleeve (5) comprises one or more grooves (8) arranged in front of the recesses (7), said recesses positioned over the side walls of the ribs (5).
  • plastic substance flows more easily into a recess (7) in front of which a groove (8) is provided.
  • ribs (6) are positioned on the part of the bearing sleeve (5) nearest to the exterior of the tub (2). Said part of the bearing sleeve (5), which is nearest to the exterior of the tub (2), tightens in the direction of the axis of the shaft (4). In this embodiment, in line with such inclination, the heights of the ribs (6) augment gradually towards the extremity of the bearing sleeve (5) ( Figure 4 and Figure 5).
  • the present invention augments in horizontal axis washer/dryers (1) the resistance of the bearing sleeve (5) against the impact of pressures that the spinning of the drum (3) creates over the shaft (4), said bearing sleeve integrated with the plastic tub (2).
  • recesses (7) provided on the side walls of the ribs (6) enable the plastic substance to come into contact with a more spacious surface, maintaining thus a more efficient integration of the bearing sleeve (5) with the tub (2).
