Definitions

  • the present invention relates to a horizontal axis washing machine.
  • the tub makes maximum displacement inside the body.
  • the maximum displacement of the tub inside the body is one of the most important factors determining the tub with the largest diameter which can be mounted inside the washing machine.
  • the object of the present invention is to design a washing machine wherein the vibration caused by the unbalanced load during the spinning cycle is reduced.
  • the washing machine realized in order to fulfill the objectives of the present invention, explicated in the first claim and the dependent claims thereof, comprises a spring anchored to the tub and a block moving inside the free space between the body and the tub attached to the one end of the spring. [0013] One end of the spring is fastened to the tub and the other end is loose to which a block hung freely without touching any entity is fastened to the other end of the spring.
  • the spring and the block are attached at the point the force exerted by the load of the tub onto the tub surface is at maximum level, or in other words, the spring and the block are attached to the part of the tub which makes the maximum displacement during the passage through resonance.
  • block is fastened to the tub with the help of more than one spring.
  • spring and block are enabled to move almost vertically to the surface of the tub by embodying springs of different characteristics.
  • washing machine comprises a guide mounted to the tub that enables the vertical movement of the spring and block to the surface of the tub.
  • this invention minimizes the maximum displacement made during the passage through resonance, it enables emplacement of a larger size tub; thus, enabling an increase in washing capacity. Furthermore, installation of dampers used as absorbers will no longer be required. Since the displacement value is decreased, bellows forming one of the connections of the tub to the body can structurally be simpler and accordingly cheaper. Moreover, the balance weights situated over the tub are not required.
  • Figure 1 - is the schematic view of a washing machine.
  • Figure 2 - is the view of the spring and the block at the highest point when the drum rotates clockwise.
  • Figure 3 - is the view of the spring and the block at the lowest point when the drum rotates clockwise.
  • Horizontal axis washing machine (1) which is the object of the present invention comprises a body (2), a drum (5) enabling the washing and rinsing by rotating about an axis and wherein the laundry (L) to be washed is emplaced, a tub (3), inside which the drum (5) which exercises rotational movements is emplaced, and one or more absorbers (4), for example a spring or a damper, which connect the tub (3) to the body (2), bear the tub (3) and the drum (5), and enable the suspension of the tub (3) in the body (2).
  • absorbers (4) for example a spring or a damper
  • the washing machine (1) also comprises a spring (6) fastened to the tub (3), a block (7) moving in accordance with the expansion or compression movements of the spring (6) inside the space between the tub(3) and the body (2) attached to the one end of the spring ( Figure 1).
  • the spring (6) enables the block (7) to move by expansion and compression movement in accordance with movement of the tub (3).
  • Block (7) exerts force to the tub (3) so as to resist against the displacement of the tub (3) inside the body (2) as the result of the movement triggered by the act of spring (6).
  • speed of angular rotation of the drum (5) equals to the natural vibration frequency (resonance) of the tub (3) and all of the elements connected to the tub (3), the tub(3) makes the maximum displacement inside the body (2).
  • the value chosen should enable the exertion of the force required for balancing the force exerted to the spring (6) during resonance.
  • spring constant is chosen at such a specific value that spring (6) makes even smaller displacements other than the resonance period. Accordingly, the force that the block (7) exerts on the tub (3) is at smaller values in conditions other than the resonance.
  • Spring (6) is situated over the tub (3) vertically. Consequently, more or less the total force exerted on the tub (3) can be transmitted to the spring (6).
  • Spring (6) and block (7) are placed inside the part of the tub (3) aligned with the point where the maximum force exerted by the load (L) on the drum (5) surface during resonance, or, in other words, they are placed inside the part of the tub which makes the maximum displacement during passage through resonance ( Figure 2 and Figure 3). Consequently, the quantity of maximum displacement of the tub (3) during resonance is decreased as a result of the force that spring (6) and block (7) exert.
  • the tub (3) suspends inside the body (2) using preferably two absorbers (4).
  • the rotation path that the tub (3) follows during the resonance is an elliptical one, the direction of the path can change in accordance with the angle at which the tub (3) is suspended inside the body (2), rotation direction of the drum (5) etc.
  • absorbers (4) are fastened at a slanting angle, when drum (5) rotates clockwise (or counter clockwise) during the resonance, the tub (3) follows a rightward (or leftward) slanting major axis elliptical path.
  • Load (L) inside the drum (5) in accordance with its weight, exerts the maximum force on the edge of the major axis of the elliptical path.
  • the spring (6) and the block (7) are mounted according to the rotation direction of the tub (3) and at a position consecutive to the lowest region of the tub (3). For example, in Figure 2 and 3, because the drum (5) rotates clockwise, the spring (6) and the block
  • block (7) is fastened to the tub (3) with the help of more than one spring (6). Accordingly, constants of springs (6) can be different from each other. Consequently, the block (7) can move almost vertically to the surface of the tub (3).
  • washing machine (1) comprises a guide (8) mounted to the tub (3) enabling vertical movement of the spring (6) and the block (7) to the surface of the tub (3).
  • the guide (8) prevents the block (7) from moving in a different direction other than the direction of the spring (6).
  • the present invention since the block (7) anchored by the spring (6) does not touch anything, the energy transmitted to the body (2) and accordingly the noise level is minimized. Since the balance weights are not required, mounting of larger size tubs (3) to the same volume of body (2) becomes possible. Under this condition, capacity of the washing machine (1) can be increased; the production of lighter washing machines becomes possible since the balance weights are not required; advantages in transportation and packaging are provided. Furthermore, the present invention also enables the use of simpler and cheaper bellows.
