Definitions

  • the subject of the present invention is a washing machine comprising a basic structure, a tub having a substantially axially symmetrical shape with respect to an axis and mounted inside the basic structure with the axis inclined to a horizontal axis, a drum for holding the laundry, mounted coaxially inside the tub and rotatable about the axis of symmetry, the tub and the drum defining a unit which oscillates inside the basic structure, and shock-absorbers operatively connected to a base of the basic structure and to the tub to limit the oscillations of the tub in operation.
  • the invention relates to a washing machine for domestic use.
  • a drum type washing machine with an outer box, a water tank which is disposed inside the outer box and a rotating tank disposed inside the water tank.
  • the water tank is mounted on shock-absorbers.
  • a front loader type of washing machine provided with at least two spring suspension units which support the drum unit from the bottom of the outer frame. Moreover are provided means for restraining the top of the drum unit comprising a non -extensible cord, cable or like element arranged to extend freely through a guide at the top of the drum unit and connected at opposite ends to the front and rear of the outer frame.
  • the rear connection incorporates a spring so that the non extensible element provides resilient support for the top of the drum unit.
  • the oscillating unit which is constituted by the tub with its counterweights, and by the drum, is suspended inside the basic structure which constitutes the outer casing of the washing machine.
  • the tub is suspended on the basic structure by means of resilient springs and at the same time is supported on the base of the basic structure with the interposition of the shock-absorbers.
  • the oscillating unit is arranged with its axis inclined to a horizontal plane.
  • the inclined axis permits the use of optimal water-column levels in a limited position in the drum, even in the presence of a small quantity of water.
  • the washing machine as described above has some disadvantages particularly connected with the problem of limiting the loads acting on the springs and on the shock-absorbers and of limiting the oscillations of the oscillating unit inside the basic structure.
  • shock-absorbers are mounted on the tub at points lying in a vertical plane perpendicular to the horizontal axis and extending through the centre of gravity of the oscillating unit.
  • a washing machine particularly for domestic use, is generally indicated 1.
  • the machine is composed of a basic structure 2 which constitutes the housing for an oscillating unit 3. As shown in Figure 1, access to the interior of the basic structure 2 is through a porthole 4.
  • the oscillating unit 3 is composed of a tub 5 having a substantially axially symmetrical shape with respect to an axis 6.
  • the front portion of the tub has an opening which faces the porthole 4 and the edges of the opening are connected to the basic structure by means of resilient couplings 7.
  • the axis 6 of the tub 5 is inclined to a horizontal axis 8 and this inclination, measured anticlockwise from the horizontal axis 8, may vary within a range of between 10° and 15°.
  • the inclination of the tub preferably adopts a value of 12° when the washing machine 1 is in the operating condition.
  • the tub 5 also comprises counterweights 9a and 9b disposed on the upper portion and on the lower portion of the tub, respectively.
  • the oscillating unit 3 comprises a drum 10 for holding the laundry.
  • the drum is coaxial with the tub and is driven by a motor and by transmission means, shown partially and indicated 11, so as to be rotatable about the axis 6.
  • an opening 12 which faces the corresponding opening of the tub 5 and the porthole 4 so as to afford access to the interior of the drum.
  • the counterweights 9a and 9b constitute parts of the oscillating unit 3 and are formed in a manner such that the centre of gravity of the oscillating unit is kept within the vertical projection of the oscillating unit in a horizontal plane, once the tub is inclined by the desired amount.
  • the counterweights 9a and 9b are also such as to shift the centre of gravity of the drum alone rearwardly relative to the baricentric plane of the unit as a whole and such that the centre of gravity of the fully-loaded drum is also shifted slightly from the vertical baricentric plane.
  • the counterweight 9a disposed on the upper portion of the oscillating unit advantageously has a substantially trapezoidal cross-section or, in any case, such as to have a greater height in the rear portion, whilst the upper surface of the counterweight is kept substantially parallel to the basic structure and the lower surface of the counterweight is kept in contact with the tub. This configuration enables approximately 80% of the weight to be kept in the rear portion of the oscillating unit.
  • the counterweight 9a is arranged symmetrically with respect to the vertical axis a-a, that is, to the line of the vertical plane containing the horizontal axis 8, and its lower surface preferably follows the external profile of the tub.
  • the counterweight 9b is arranged below and entirely in a position at the front of the oscillating unit. Moreover, considering the two portions into which it is divided by the axis a-a, a first portion corresponding to the right-hand portion including the motor will consequently have less weight than a second portion corresponding to the left-hand portion which does not include the motor.
  • the weight of the left-hand portion is greater than the weight of the right-hand portion by a value calculated in dependence on the weight of the motor and of its eccentricity and is preferably greater than or equal to twice the weight of the right-hand portion.
  • the weights of the two counterweights 9a and 9b are preferably interdependent.
  • the weight of the upper counterweight 9a is indicated P and the weight of the lower counterweight 9b is indicated p, the following is preferably true: 21/15 ⁇ P/p ⁇ 43/27. This proportion is obtained owing to the fact that the percentage variation in the angle of the tub when it is empty and when it is fully loaded is preferably between 0.1 and 0.2 for the corresponding initial angle values of between 12° and 15°.
  • the entire oscillating unit 3 is suspended inside the basic structure 2.
  • the tub 5 is supported from below by two shock-absorbers 13 each having an end 13a connected to the tub and an end 13b connected to a base 14 of the basic structure 2.
  • shock-absorbers 13 have the purpose of limiting the oscillations of the oscillating unit 3, and particularly of the tub 5, when the washing machine 1 is in operation.
  • the shock-absorbers 13 are mounted on the tub in an original manner at points lying in a vertical plane 15 perpendicular to the horizontal axis 8 and extending through the theoretical centre of gravity of the tub 5 and of the drum 10, that is, of the oscillating unit 3 including the counterweights 9a and 9b.
  • the vertical plane 15 is illustrated by its line in the plane of the drawing and, in particular, the shock-absorbers 13 are aligned along this line, that is, they have axes which lie in the vertical plane 15.
  • the shock-absorbers 13 are arranged on opposite sides of a vertical axis of symmetry and each is preferably inclined at approximately 10°-12° to a vertical line 15a when unloaded.
  • the two shock-absorbers are inclined in a manner such that the distance between the two is greater at the points at which they are connected to the base of the basic structure than at the point at which the shock-absorbers are connected to the tub. If the distance between the points at which the two shock-absorbers are connected to the base of the basic structure is indicated A and the distance between the two points at which the shock-absorbers are connected to the tub is indicated B, A is therefore greater than B and, in particular, is advantageously greater by 20-22%.
  • each shock-absorber 13 is connected to the tub 5 is arranged 45° from the vertical axis extending through the centre line of the tub.
  • Each shock-absorber 13 and, in particular, each of its ends 13a and 13b, is connected to the tub 5 or to the base 14, respectively, by an articulated connection 16 with the interposition of at least one resilient vibration-damping element 17 of known type.
  • the resilient element 17 which is present in the lower connection, that is, that between the shock-absorber 13 and the base 14 of the basic structure 2, is compressed between the respective shock-absorber 13 and a bracket fixed firmly to the basic structure 2.
  • the resilient element 17 may be compressed axially relative to the articulated connection 16, or radially, or in both directions.
  • the resilient element 17 may advantageously be made of a material having a hardness value of about 63° Shore, insofar as production tolerances allow.
  • the inclination of the tub 5 allows the deformability of the resilient element 17 to be utilized fully so that it is always working not only in response to a vertical force component but also in response to oscillations of the oscillating unit relative to the horizontal axis 8, in the plane of Figure 1.
  • the oscillating unit 3 and, in particular, the tub 5 is also suspended inside the basic structure 2 by means of resilient components 18 fastened to the upper portion of the tub 5.
  • the resilient components 18 are also fastened to the tub at points lying in the vertical plane 15 perpendicular to the horizontal axis 8 and extending through the centre of gravity of the oscillating unit 3.
  • the resilient components 18 have axes which lie in the vertical plane 15 and which are therefore aligned with the respective shock-absorbers disposed at the bottom.
  • each resilient component 18 is inclined to a vertical line 15a.
  • Each component is preferably inclined at 15° to the vertical line.
  • the two resilient components 18 also have opposite inclinations.
  • the two resilient components 18 are inclined in a manner such that the distance between the two is greater at the level of the connection to the basic structure than at the points at which the resilient components are connected to the tub. If the distance between the points at which the two resilient components are connected to the basic structure is indicated C and the distance between the two points at which the resilient components are connected to the tub is indicated D, D is therefore less than C and, in particular, is advantageously less by about 14%.
  • the oscillating unit and the respective resilient suspension components and shock-absorbers are substantially in line vertically.
  • the oscillating unit is extremely free and can oscillate, hinged on the resilient suspension components, loading both the shock-absorbers and the resilient vibration-damping elements 17 in a symmetrically oriented manner so that the particular configuration described above enables, in particular, a damping oscillatory motion to be achieved.
