Definitions

  • the present invention relates to a horizontal axis washing machine having a drying function.
  • the drum is beared by the tub with the roller bearings assembled on the rear wall of the tub. Accordingly, the magnitude of the relative movements between the tub and the drum is at a minimum in the center of the bearing. The amount of the movement increases as moved away from the center. And consequently, the distance of the support arms disposed on the rear wall of the drum nearest to the tub is configured to increase as moved away from the center depending on the bending motion of the drum.
  • the region that contains the seam joining the front and rear lids of the drum and the drum body is the region that is subjected to the maximum amount of translatory motion resulting from the bending of the drum which, as a rotating part, is most subjected to the bending moment. Accordingly, particularly in washing machines wherein a plastic tub is used, the seam contacts with and scrapes the rear wall of the tub. Therefore, the distance remaining between the tub and the drum should be adjusted properly.
  • the object of the present invention is to design a washing/drying machine comprising a drum wherein the usable volume is increased by decreasing the space between itself and the tub.
  • the washing machine realized to fulfill the object of the present invention, explicated in the first claim and the respective claims thereof, comprises a housing formed on the tub walls, coinciding with the seam along the line on the rear wall of the tub.
  • the housing forms a recess on the surface of the tub walls facing the drum.
  • the housing extends along a preferably circular line on the front and rear wall.
  • the depth of the drum is increased by protecting the distance between the seam and the tub and without changing the size and shape of the seam.
  • the dimensions of the drum are increased by keeping the dimensions of the tub the same.
  • the housing is disposed on the rear wall of the tub, at the level of the seam, where the distance between the drum and the tub rear wall is the most. In this case, the contact of the seam with the tub rear wall is prevented even in conditions wherein the drum is in the most translated positions due to unbalanced load or similar reasons.
  • FIG. 1 is the perspective view of a washing machine.
  • Figure 2 - is the cross-sectional view of the drum and the tub in the state of the art.
  • Figure 3 - is the cross-sectional view of a drum and a tub.
  • Figure 4 - is the partial rear view of the tub.
  • Figure 5 - is the partial view of the tub from another angle.
  • the washing machine (1) of the present invention has a horizontal axis and comprises a cylindrical tub (2) having a front wall (60), a rear wall (6) and a side wall and a drum (3) assembled into the said tub (2) ( Figure 1).
  • the drum (3) comprises:
  • the washing machine (1) comprises a housing (5), disposed on the front and/or the rear wall (6, 60), that extends at the level of the seam (4), along the line wherein the walls (6, 60) and the side wall join.
  • the housing (5) preferably extends all around on the walls (6, 60).
  • the housing (5) is disposed at the position where the seam (4) can reach on the tub (2) at the excessive displacements of the drum (3) in the horizontal plane ( Figure 3).
  • the housing (5) is disposed opposite the seam (4) and in the same horizontal direction as the seam (4) on the portion of the walls (6, 60) whereto the seam (4) corresponds and forms a recess on the surface of the tub (2) walls (6, 60) facing the drum (3) ( Figure 4 and Figure 5).
  • the housing (5) is sized such that it prevents the seam (4) from entering into the housing (5) and impact with the walls (6, 60) even in the excessive displacements of the drum (3) on the tub (2) in the horizontal plane.
  • the depth of the drum (3) is increased, by protecting the distance between the seam (4) and the tub (2), without changing the length of the seam (4) formed outside the body (7) and towards the tub (2). Consequently, even if the depth of the housing (5) is not too large, a considerably wide cylindrical volume is gained behind the drum (3). This volume can be utilized for increasing the volume of the drum (3) if the dimensions of the tub (2) are kept the same.
  • the drum (3) is beared by the tub (2) at the center of the tub (2) rear wall (6). Accordingly, the movements of the tub (2) and the drum (3) are at minimum in this section where the drum (3) is beared by the tub (2). The amount of movement of the tub (2) and the drum (3) increases as moved away from this section in the radial direction. Therefore, the distance of the drum (3) rear wall nearest the tub (2) from the tub (2) rear wall (6) is adjusted to increase as moved away from the center, depending on the bending motion of the drum (3). The distance of the drum (3) farthest away from the tub (2) rear wall (6) is the section wherein the seam (4) is contained on the drum (3).
  • the housing (5) is disposed on the rear wall (6) of the tub (2), precisely aligned with the said seam (4), and the contact of the seam (4) with the rear wall (6) of the tub (2) is prevented even in conditions wherein the drum (3) is in the most translated position due to unbalanced load or similar reasons.
  • the tub (2) is preferably produced of a plastic material.
  • the tub (2) is produced of metal.
  • the housing (5) is shaped as a protuberance and is formed on the walls (6, 60) by the deep drawing method.
