Definitions

  • the present invention relates to a front-loading home laundry washing machine, to which the following description specifically refers purely by way of example without this implying any loss of generality.
  • a front-loading home laundry washing machine generally comprises: a substantially parallelepiped-shaped, self-supporting boxlike outer casing structured for resting on the floor; a substantially horizontally-oriented and nearly cylindrical, cup-shaped washing tub which, in use, contains the washing liquid and is suspended in floating manner inside the casing, with the front mouth directly facing a laundry loading-unloading through opening formed in the front wall of the casing; a substantially cylindrical, cup-shaped rotatable drum which is structured for accommodating the laundry to be washed, and is fitted in axially rotatable manner inside the washing tub with the concavity facing the laundry loading-unloading opening, so as to be able to freely rotate inside the washing tub about its substantially horizontally-oriented, central axis locally coinciding with the longitudinal axis of the washing tub; an elastically-deformable bellows which watertight connects the front mouth of the washing tub to the laundry loading-unloading opening formed in the front wall of the casing; a porthole door which is hinged
  • the laundry washing machine is furthermore characterized in that the annular housing has a tubular structure with a substantially polygonal-shaped, transversal cross-section.
  • the laundry washing machine is furthermore characterized in that the annular housing includes an inner annular hemishell and an outer annular hemishell which are discrete and complementary to one another, extend astride of the midplane of the annular housing, are concentric to one another and are finally joined to one another so as to form/delimit the annular inner cavity of said annular housing.
  • washing tub 3 is preferably suspended in floating manner inside the boxlike casing 2 via a suspension system that preferably comprises at least one, and preferably a couple of coil springs 10 connecting the upper portion of washing tub 3 to the top of casing 2, and preferably at least one and more conveniently a couple of vibration dampers 11 connecting the bottom portion of washing tub 3 to the bottom of casing 2.
  • a suspension system that preferably comprises at least one, and preferably a couple of coil springs 10 connecting the upper portion of washing tub 3 to the top of casing 2, and preferably at least one and more conveniently a couple of vibration dampers 11 connecting the bottom portion of washing tub 3 to the bottom of casing 2.
  • the rotatable drum 4 is preferably substantially cup-shaped and is fitted in axially rotatable manner inside the washing tub 3 with its concavity facing the front mouth of washing tub 3.
  • the rotatable drum 4 is furthermore arranged inside washing tub 3 with the drum rotation axis A locally substantially coaxial to the longitudinal axis of washing tub 3, and with its nearly circular front mouth directly aligned and faced to the front mouth of washing tub 3, so as to receive the laundry to be washed through the laundry loading-unloading opening present on front wall 9.
  • the drum rotation axis A is preferably substantially horizontal.
  • the polygon defining/resembling the transversal cross-section of inner cavity 16, or rather of annular housing 15, preferably has at least five sides.
  • both annular hemishells 18 and 19 preferably extend astride of the midplane P of annular housing 15 and the annular hemishell 19 surrounds the annular hemishell 18.
  • the transversal cross-section of outer annular hemishell 19, therefore, includes the first and second consecutive sides of the polygon defining/resembling the transversal cross-section of annular housing 15.
  • the inner annular hemishell 18 is preferably provided with a first wall segment 21 and a second wall segment 22 nearly faced and non-parallel to one another, and a third wall segment 23 connecting the first wall segment 21 to the second wall segment 22.
  • consecutive wall segments 21 and 23 of annular hemishell 18 are preferably arranged substantially astride of the midplane P of annular housing 15, are inclined to one another and are both non-perpendicular to the midplane P.
  • the wall segments 21 and 23 of annular hemishell 18 therefore correspond to the third and fourth consecutive sides of the preferably irregular, simple polygon defining/ resembling the transversal cross-section of annular housing 15.
  • the annular hemishells 18 and 19 are preferably shaped so that the two annular rims/edges 18a and 18b of annular hemishell 18 and the two annular rims/edges 19a and 19b of annular hemishell 19 are located/extend/lie on a same/common frustoconical surface which is coaxial to the central axis B of annular housing 15 and has an opening angle lower than 150°.
  • annular rims/edges 18a, 18b, 19a and 19b of the annular hemishells 18 and 19 are located/extend/lie on a frustoconical surface whose generatrix f is preferably inclined with respect to central axis B by an angle ⁇ roughly equal to 15°.
  • the balancing ring 13 may lack the dumbing liquid.
