Definitions

  • This invention relates to attaching a balance weight to a washing tank used in a washer/dryer.
  • a washer with an internal diameter size limiting the stretching of the plastic component beyond a specific value is utilized. Setting the dimensions of the internal diameter of the washer to be utilized and the diameter of the connection holes of the balance weight, in relation to each other, is critical ( Figure 4). Plastic extensions on the washing tank should be stretched with a screw just enough to be able to hold the balance weight and this operation should not cause the formation of cracks on the balance weight. A possible time-dependent change in the dimension of the connection hole diameter of the balance weight and yielding of plastic material cause the force to fix the balance weight to drop.
  • the balance weight starts to slightly loosen, increases the amplitude of the motion as it enlarges the space for its own on the plastic extensions in time and, causes the noise level to increase during operation.
  • the pre-stressed bolt itself is utilized ( Figure 2) or a spring washer is used to ensure the desired pre-stress ( Figure 3).
  • German Patent Document DE 4238686 a description is given of an application wherein the bolt of the plastic is attached with a spring washer in order to prevent the loosening that results from the yielding of the plastic material in time.
  • a pre-stress is formed by the deflection of the spring washer in the axial direction.
  • the balance weight with a concrete main body which is used in a washing machine is supported with metal reinforcement components and, by screwing the connecting elements connected to the said reinforcement components it is attached to the washing tank of the washing machine.
  • the aim of the present invention is the realization of a washer/dryer comprising a connection mechanism whereby it is prevented that the balance weight attached to the washing tank loosens in time and detaches from its fixed position.
  • Fig.l - is a schematic view of a washer/dryer.
  • Fig.2 - is a sectional view of a washing tank of a washer/dryer and a balance weight attached to the said washing tank by means of an pre-stressed bolt, in the state of the art.
  • FIG.3 - is a sectional view of a washing tank of a washer/dryer and a balance weight attached to the said washing tank by means of a spring washer, in the state of the art.
  • FIG.4 - is a sectional view of a washing tank of a washer/dryer and a balance weight attached to the said washing tank by means of a washer the internal diameter size of which is fixed, in the state of the art.
  • Fig.5 - is a sectional view of an extension located on a washing tank.
  • Fig.6 - is a sectional view of a balance weight.
  • Fig.7 - is an A-A sectional view of an extension.
  • Fig.8 - is a sectional view of a spring washer.
  • Fig.9 - is a perspective view of a spring washer.
  • Fig.10 - is a sectional view of a spring washer that fits onto an extension.
  • Fig.l 1 - is a sectional view of a connection mechanism whereby the washing tank — balance weight connection is established, not assembled.
  • Fig.12 - is a sectional view of a connection mechanism whereby the washing tank — balance weight connection is established, assembled.
  • the washer/dryer (1) comprises a body (2), a drum (3) where laundry is placed into, a washing tank (4) manufactured from plastic material where the drum (3) moves in, a balance weight (5) manufactured from concrete material, which assists to attenuate the forces applied during operation by increasing the inertia of the washing tank (4) and, one or more than one connection mechanism (6) whereby the balance weight (5) is attached to the washing tank (4).
  • the connection mechanism (6) comprises one or more extensions (boss) (7) located on the front wall of the washing tank (4), manufactured via plastic injection to be single piece with the washing tank (4), whereby the balance weight (5) attached onto the washing tank (a) is carried and wherein its end comes out of the other side of the balance weight (5) as a distance X as the balance weight (5) is attached, an extension housing (8) which is positioned in the balance weight (5) and where mentioned extension (7) passes therethrough, a screw (9) whereby it is achieved to extend the extension (7) to the sides and to lean it against the extension housing (8) internally, by being screwed to the interior of the extension (7) and, a spring washer (10) located between the screw (9) and the extension (7), whereby it is accomplished to attach the balance weight (5) to the washing tank (4) as pre-stressed and with a gap-free and flexible connection method by applying both a radial and an axial force.
  • extensions located on the front wall of the washing tank (4), manufactured via plastic injection to
  • the extension (7) comprises a screw hole (11) where the screw (9) fits into, more than one extension leg (12) which leans against the interior of the extension housing (8) by being extended to the sides as the screw (9) is screwed to the screw hole (11) and, one or more than one split (13) which is used to facilitate the extension legs (12) to extend as mentioned.
  • the spring washer (10) comprises a free height (H) which is preferably longer than the length (X) of the portion of the extension (7) that comes out of the balance weight (5).
  • H free height
  • the spring washer (10) comprises a curvilinear pressure surface (14) which stretches and extends along the radial direction and prevents the balance weight (5) from moving back and forth by continuously applying a pressure in the direction of screw (9) tightening as the screw (9) is screwed to the extension (7) and, whereby it is achieved that it slides on the balance weight (5) meanwhile applying a pressure onto the said balance weight (5) as mentioned, a washer hole (15) the edges of which curve towards the screw hole (11) as it fits onto the extension (7) and the edges of which apply a pressure to the screw hole (11) in radial direction as being forced by the screw (9) head and, an extension fitting surface (16) which fits onto the extension legs (12) and permits said extension legs (12) to stretch outward.
  • the extension fitting surface (16) permits the portion of the extension legs (12) which is located outside of the balance weight (5) to extend to the sides for a certain amount.
  • extension legs (12) tightly lean against the internal wall of the extension housing (8).
  • the portion (X) of the extension (7) that comes out of the balance weight (5) circumferentially extends for a certain amount permitted by the extension fitting surface (16). This amount is larger than that of the portion that is located inside the extension housing (8) and thereby, the balance weight (5) is prevented from sliding on the extension (7).
  • the pressure surface (14) prevents the balance weight (5) to move back and forth and cause a gap in time.
  • the spring washer (10) comprises a hat form which circumferentially fits onto the extension legs (12) covering from the tips ( Figure 8, Figure 9).

Abstract

La présente invention concerne un mécanisme de connexion (6) utilisé dans des lave-linge/sèche-linge (1), qui comprend une rondelle élastique (10) servant à fixer la masse d'équilibrage (5) sur la cuve de lavage (4) sans qu'il existe d'espace entre ces dernières. La masse d'équilibrage (5) vise à atténuer les forces appliquées pendant le fonctionnement du fait qu'elle augmente l'inertie de la cuve de lavage (4), de sorte qu'un certain relâchement dépendant du temps, en fonctionnement, est compensé et que le niveau sonore ne peut augmenter, lorsque, éventuellement, la masse d'équilibrage (5) se détache de sa position fixe retenue.
