Definitions
- the present patent application relates to a system used to fix the two semi-shells of plastic tanks for washers, washer/dryer combos and similar appliances, and to the tank obtained with the said innovative technology.
- the aforementioned household appliances are provided with a fixed, basically cylindrical tank, moulded from plastic material (mostly polypropylene) and provided with a large front opening used to load laundry inside the traditional rotating drum.
- plastic material mostly polypropylene
- a similar tank is composed of two different semi-parts (or semi-shells) that are engaged and fixed by means of front coupling, in an orthogonal plane with respect to the longitudinal axis of the tank.
- each semi-shell is coupled after the traditional drum is placed in intermediate position between the two semi-shells, in order to be housed inside the tank.
- the circular opening of each semi-shell is provided with a perimeter border that protrudes outwards that acts as a flange.
- This fixing is obtained by means of an annular band designed to be closed with a screw; it being provided in particular that a similar band, suitably provided with a circumference that basically corresponds to the tank, has an upturned U-shaped transversal section that allows it to be exactly positioned on the protruding profile on the external perimeter of the tank, before being energetically tightened by means of the said screw.
- the energetic tightening of the band prevents the accidental uncoupling of the two flanges that form the protruding profile that is matched to the said band.
- the mutual fixing of the two flanges is obtained by means of a series of clamps mounted at a suitable distance astride the profile formed by the said flanges.
- fixing can also be obtained by means of a series of suitably spaced screws engaged in transversal direction within suitable pairs of threaded holes provided in aligned position on both flanges.
- the need to eliminate the complications of the aforementioned operations and simultaneously reduce production time has led to the development of the new fixing system that is the object of the present patent application.
- the new system is especially appreciated because it provides perfect hermetic seal between the flanges of the two semi-shells and mutual fixing, by means of a single, practical and quick operation.
- This particular technique basically consists in the application of an adhesive layer in intermediate position between the two interfaced surfaces of the two flanges, following to physical-chemical activation of the interested surfaces.
- the preliminary activation is necessary because the polypropylene that is traditionally used to produce the said semi-shells would not permit the stable energetic adhesion to the aforementioned adhesive layer.
- a similar chemical-physical activation of the surfaces to be adhered can be obtained by alternatively using the so-called “atmospheric plasma”, “crown”, “flame (methane)” or “UV- Ozone” techniques.
- the fixing system of the invention allows to uncouple, if necessary, the two semi-shells that were coupled by means of the said adhesion technique with prior physical-chemical activation.
- - figure 1 is the axonometric view of the tank obtained by using the new fixing system of the invention
- FIG. 2 is a cross-section with a transversal plane of a section of the perimeter profile formed on the outside of the tank by means of the cooperation of the two outward protruding flanges that surround the opening of the two semi-shells of the tank.
- the system of the invention is designed to fix the two semi-shells (1 , 2) of a traditional tank (V) for washers, washer/dryer combos and similar appliances.
- the openings of the two semi-shells (1 , 2) are usually provided with outward protruding perimeter flanges (10, 20) that are basically designed to be interfaced at very short distance.
- the flange (10) of the first semi-shell (1) is situated in slightly backward position with respect to the opening (1a) of the semi-shell (1 ), and the flange (20) of the second semi-shell (2) is flush with the opening (2a) of the semi-shell (2); it being provided that the opening (2a) has a slightly larger diameter than the back section due to the presence of an intermediate connection step (2b).
- the flanges (10, 20) are brought in a very close position that is useful for the execution of the fixing system of the invention.
- the two flanges (10, 20) are preferably provided with a basically sinusoidal profile (10a, 20a) on the internal surfaces. This has been studied to increase the useful surface of each flange

Abstract
L'invention concerne un système utilisé pour fixer les demi-coques (1, 2) de cuves en plastique (v) pour lave-linge, combinés lave-linge/sèche-linge et appareils similaires; lesdites cuves étant en plastique, de préférence en polypropylène, et étant formées par deux demi-coques pouvant être appariées, dont les ouvertures sont entourées par des brides (10, 20) faisant saillie vers l'extérieur qui favorisent un raccordement stable des demi-coques. Le système de l'invention est caractérisé en ce que les brides des demi-coques sont fermement assemblées par une couche adhésive intermédiaire (3) appliquée après activation physique-chimique des surfaces intérieures (10a, 20a).
