Definitions

  • the present invention relates to a washing machine with increased washing performance wherein the washed laundry is prevented from wearing out.
  • the washing machines particularly the front loading washing machines with horizontal axis, comprise a tub situated inside the body and a perforated drum that provides washing of the laundry by rotating in the tub.
  • openings are provided in the body, the tub and the drum that overlap with each other. These openings are closed by a lid situated on the body.
  • a bellows situated between the tub and the front wall of the body at the area of the opening provides the washing liquid and the laundry to stay in the drum.
  • the bellows by means of its resilient configuration, provides an effective leak-proofing between the front wall of the body and the tub that moves by the motion of the drum rotating inside during the washing and the spinning processes.
  • the lid comprises a frustoconic shaped glass that extends from the front wall of the body into the drum.
  • the glass keeps away the laundry from the bellows and prevents them from getting caught inside the bellows and wearing out.
  • the gap between the glass and the drum should be narrowed. The more the gap between the glass and the drum front wall is narrowed, the less is the possibility of the laundry passing through this gap and get caught in the bellows.
  • the gap between the glass and the drum front wall gets narrower, the drum hits the glass during the washing and the spinning processes. Therefore, a relatively wide gap is let between the glass and the dram front wall and the glass is extended further into the drum by increasing its depth in order to keep away the laundry from the bellows.
  • the object of the present invention is the realization of a washing machine comprising a lid having a glass that prevents laundry from getting caught in the bellows, increases the washing performance and is prevented from being broken as a result of hitting the front wall of the drum.
  • the glass extends from the front wall into the drum and the tub when the lid is closed.
  • the glass prevents the laundry from getting near the bellows and hence to get caught in the bellows.
  • the portion of the glass aligned with the opening of the drum has an elliptical cross section. Consequently, by decreasing the distance between the drum opening and the right and lei sides of the glass, it is made harder for the laundry to get caught in the bellows.
  • the depth of the glass upper portion being less than the depth of the lower portion, the possibility is decreased for the drum opening to hit and break the glass.
  • figure 1 - is the schematic view of a washing machine when the lid is closed.
  • figure 2 - is the schematic view of a washing machine when the lid is open.
  • figure 3 - is the A-A sectional view of the glass when the lid is closed.
  • figure 4 - is the B-B sectional view of the glass when the lid is closed.
  • the washing machines (1) comprise a body (2) having a front wall (7), a tub (3) in which the washing process lakes place, a drum (4) situated inside the tub (3) into which laundry is emplaced to be washed, a loading port (5) situated on the front wall (7) providing access into the tub (3) and the drum (4), and a lid (6) covering the loading port (5).
  • the lid (6) comprises a frame (8) and a glass (9) arranged in the center of the frame (8), that extends from the loading port (5) towards the inside of the drum (4).
  • the washing machine (1) is a front- loading type with a horizontal axis.
  • the washing machine (1) also comprises a tub opening (11) that corresponds to the loading port (5), situated at the plane of the tub (3) lacing the front wall (7), a drum opening (10) that corresponds to the loading port (5), situated at the plane of the drum (4) lacing the front wall (7), and a bellows (12), with one end attached to the side of the tub opening (11) and the other to the side of the front wall (7), that provides the leak-proofing between the front wall (7) and the tub (3) that moves with the motion of the rotating drum (4) by means of its resilient configuration.
  • the loading port (5), the tub opening (11) and the drum opening (10) are all circular.
  • the glass (9) has a frustoconic shape.
  • the width (d3) of the gap (y) at the right side of the glass (9) and the width (d4) on the left side of the glass (9) is less than the width (dl) of the gap (y) at the upper side of the glass (9) and the width (d2) on the lower side of the glass (9). Consequently, the possibility of the laundry to get caught in the bellows (12) from the portions of the gap (y) on the right and left sides of the glass (9) is lowered. Furthermore, the laundry that gets caught in the bellows (12) is pushed into the drum (4) by means of the elliptical cross section of the glass (9) portion at the level of the drum opening (10).
  • the width (d3) of the gap (y) on the right side of the glass (9) is almost equal to its width (d4) on the left side of the glass (9).
  • the width (dl) of the gap (y) on the upper side of the glass (9) is almost equal to its width (d2) on the lower side of the glass (9).
  • the depth of the glass (9) is reduced since the possibility of the laundry to get caught in the bellows (12) from the portions of the gap (y) on the right and left sides of the glass (9) is lowered by means of the elliptical cross section of the glass (9) portion aligned with the drum opening (10) when the lid (6) is closed.
  • the depth (hi) of the upper portion of the glass (9) is less than the depth (til) of the lower portion of the glass (9). Consequently, the volume that is occupied by the glass (9) within the drum (4) is reduced. Also, the possibility of the glass (9) breaking as a result of being hit by the drum opening (10) is reduced.
  • the angle (al) between the upper portion of the glass (9) and the central axis (e) of the lid (6) is greater than the angle (a2) between the lower portion of the glass (9) and the central axis (e) of the lid (6).
  • a collapsed portion is provided at the center of the glass (9) that contributes to directing the laundry towards the inside of the drum (4) during washing.
