Definitions

  • the present invention refers to household washing machines, wherein it should straightaway be made clear that this term is used here to cover both clothes washing machines and the so called washer-driers, le combined clothes washing and drying machines
  • Machines of the above cited kind are commonly known to comprise an outer casing that encloses a suspended washing assembly along with a whole set of functional component parts and is furthei provided with a facia panel or control board wheie the vaiious contiol and adjustment means of the machine are arranged
  • Said washing assembly comprises in turn a tub that houses a drum rotating about a substantially horizontal axis In highei -performance models, it further houses an airangement, typically known as 'jet system' in the art, to lecirculate both the washing and the rinsing liquor
  • the outei casing of the washing machine compnses a door which, in a first topology of such machines, is located on the top side and, in a second topology, on the fiont side theieof In the latter case, the door is usually made m the form of a circulai porthole window
  • the door, or lid, arranged on the top side of the machine advantageously enables the user of the same machine to avoid bending down, le.
  • Washing machines provided with a front door m the form of a porthole window are also known, for instance from FR-A-1 594 442 which is believed by the Applicant to be the most lelevant document representing the state of the art, in which the axis of the rotating drum is inclined with respect to a horizontal plane
  • FR-A-1 594 442 which is believed by the Applicant to be the most lelevant document representing the state of the art, in which the axis of the rotating drum is inclined with respect to a horizontal plane
  • FIG. 1 is a simplified perspective, partially see-through view of a free-standing washing machine according to the present invention
  • FIG. 2 is a cross-sectional, again simplified view of the same washing machine according to a longitudinal vertical plane
  • an outer casmg 10 of a free-standing (le installed directly on the floor P of a loom) washing machine comprises a worktop 20 an inclined front facia panel 30 carrying the control and adjustment means 31 of the machine as well as the washing aids dispenser 32, and a door 50 m the form of a circular see-through porthole window foi loading and unloading the washload
  • the front face of the outei casing 10 (which is manufactured out of a smgle sheet-metal piece with the associated left-hand and right-hand sides of the same casmg) consists of an inclined and convex central portion 11 and two curvilinearly faceted side portions as the one indicated at 12 m Figure 1
  • said front face of the outer casing 10 blends smoothly, le without any interruption of continuity, into the visible surface of the facia panel 30, which is shaped m a similar way
  • an oscillating washing assembly 70 Inside the outei casmg 10 there are arranged an oscillating washing assembly 70 and well-known functional component parts (such as pumps, water-level and wash-liquoi tempeiature controls, programme sequence control means, lmt filters and the like) which aie not shown here for reasons of greater simplicity
  • the washing assembly 70 compnses (further to the component parts, again not shown, of an arrangement geneially known as 'jet system' for recirculating the wash and rinse liquor) a tub 71 and a drum 72 which is housed m the tub 71 and is adapted to rotate about an axis X that is inclined with respect to the floor P by an angle ⁇ of less than 15°, preferably of approximately 10°

  • the frame 51 which delimits the circular porthole 50 on the front side, is not symmetric, but has a width (thickness) that is greater in its lower part than in its upper part, owing to the fact that the centre of the outer circumference 52 of the frame 51 is situated on the rotation axis X of the drum 72, while the centre of the inner circumference 53 of the same frame 51 coincides with the centre of the porthole 50 and is therefore situated in a higher position.
  • This feature is instrumental in further promoting the visibility of the interior of the
  • the position of the centre 55 of the porthole 50 is relatively high, notwithstanding the fact that the machine (as this has been stated earlier in this description) has its control panel 30 on the front side thereof, rather than in a console on the rear side as in the case of some machines that are currently produced in the USA by another manufacturer.

  • h 0.50 H in traditional washing machines. This arrangement therefore constitutes an additional advantage for the user of a washing machine according to the present invention.
  • a washing machine according to the present invention has the additional advantage of practically requiring the same amount of floor space P as the one occupied by a traditional washing machine with the same performance capabilities (ie. washload capacity, revolving speed of the rotating drum, etc.).

Abstract

L'invention concerne un lave-linge à usage domestique, qui comprend une carrosserie externe (10) comportant un tableau de commande frontal (30) et une porte (50) de chargement et de déchargement du linge, située en dessous dudit tableau et se présentant de préférence sous forme de hublot circulaire. L'ensemble de lavage suspendu (70) de la machine comprend une cuve (71) et un tambour (72) tournant autour d'un axe (X) incliné par rapport à l'horizontale. De préférence, la machine comporte, pour faire circuler l'eau de lavage et de rinçage, un système connu. Un joint statique (75) du type à soufflet permet de relier les uns aux autres les ouvertures associées de la partie avant de la carrosserie (10), la cuve (71) et le tambour (72). Le diamètre (R0) de l'ouverture du tambour (72) devant les soufflets (75) est égal au moins aux deux tiers du diamètre (RB) de l'enveloppe, c'est-à-dire du manteau cylindrique latéral dudit tambour (72), de préférence (R0) ≃ 0,70(RB).
