    • a closing cover that couples with the upper edges of the lateral walls and the internal walls of the shower group, so as to delimit and isolate the storage chambers of the water and conveying channels of the water.

  • In a novel way, the device (1) for a washing machine for supply of water comprises a plurality of assembly channels (6) defined, in a coupling configuration (Z), by the closing cover (5) and the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2).
  • The assembly channels (6) advantageously have plastic material (7) (for example thermoplastic, heat-hardening plastic, etc.) injected therein, by means of injection moulding, so as to isolate and delimit the storage chambers (3) of the water and the conveying channels (4) of the water.
  • In a first embodiment, illustrated in figures 5, 5A and 5B, the assembly channels (6) are defined by first grooves (50) realised in the closing cover (5) with the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2) being faced to the first grooves (50) in the coupling configuration (Z).
  • In a second embodiment, illustrated in figures 4, 4A and 4B, the assembly channels (6) are further defined by second grooves (250) realised in the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2).
  • In the coupling configuration, the second grooves (250) face the first grooves (50), so as to define the assembly channels (6).
  • In a third embodiment, illustrated in figures 6, 6A and 6B, the assembly channels (6) can be defined by projections (350) which extend from the upper ends (200) of the lateral walls (20) and of the internal walls (25) of the shower group (2).

  • The closing cover (5) can be complementarily profiled with respect to the storage chambers (3) and the conveying channels (4) of the shower group (2). Concerning the method for realising the device (1) of the invention for a washing machine for supply of water into the trays of the washing machine containing detergents, in known ways as described in the preamble, it comprises:
    • providing a shower group (2) which comprises a perforated base (28) from which a plurality of lateral walls (20) and internal walls (25) extend which define water storage chambers (3) and channels (4) for conveying the water to the storage chambers (3), the shower group (2) being installable in the washing machine so that the perforated base (28) is arranged above the trays and faces the trays in order to enable water supply contained in the storage chambers (3);
    • providing a closing cover (5) able to couple with the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2) which define the storage chambers (3) and the conveying channels (4) (figures 4B, 5B).
  • In a novel way, the method for realising the device (1) of the invention for a washing machine for supply of water into the trays of the washing machine containing detergents further comprises following operating steps:
    • providing a mould containing the shower group (2) and the closing cover (5) in a coupling configuration (Z), so as to identify a plurality of assembly channels (6) defined by the closing cover (5) and the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2) (figures 4A, 5A);
    • injection of plastic material (7) internally of the assembly channels (6), so as to isolate and delimit the storage chambers (3) of the water and conveying channels (4) of the water (figures 4, 5).
  • By way of example, providing a mould containing the shower group (2) and the closing cover (5) in a coupling configuration (Z) comprises:
    • providing a first matrix containing the shower group (2) and providing a second matrix containing the closing cover (5);
    • mutual positioning of the first matrix and the second matrix so as to arrange the shower group (2) and the closing cover (5) in the coupling configuration (Z).
  • In particular, the mutual positioning of the first matrix and the second matrix can comprise a translation and/or rotation movement.
  • By way of example, translation of the second matrix containing the closing cover (5) can be included so as to face the closing cover (5) to the shower group (2) contained in the first matrix, to define the coupling configuration (Z).
  • Alternatively the first matrix containing the shower group (2) can be translated so as to face the shower group (2) to the closing cover (5) contained in the second matrix.
  • A further possibility is to rotate the second matrix containing the closing cover (5) so as to face the closing cover (5) to the shower group (2) contained in the first matrix, or alternatively to rotate the first matrix containing the shower group (2) so as to face the shower group (2) to the closing cover (5) contained in the second matrix.
  • The mutual positioning of the first matrix and the second matrix might include a combined translation and rotation movements.
  • In a first mode of actuation, the injection of plastic material (7) internally of the assembly channels (6) comprises an injection internally of the first grooves (50) realised in the closing cover (5) with the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2) being faced to the first grooves (50) in a coupling configuration (Z) (figures 5, 5A, 5B).
  • In a second embodiment, the injection of plastic material (7) internally of the assembly channels (6) further comprises the injection internally of the second grooves (250) realised in the upper ends (200) of the lateral walls (20) and the internal walls (25) of the shower group (2) (figures 4, 4A, 4B).
  • In this case the first grooves (50) facing the second grooves (250) in a coupling configuration (Z), define the assembly channels (6) (figure 4A).
  • On the basis of the preceding description it is very clear that the proposed device for a washing machine for supply of water to the trays of the washing machine containing detergents enables a rapid and simple assembly of the shower group and the closing cover.
  • This is fundamentally owed to the realisation of a plurality of assembly channels defined, in the coupling configuration, by the closing cover and the upper ends of the lateral walls and the internal walls of the shower group; the assembly channels having plastic material (7) injected therein by means of injection moulding (e.g. thermoplastic, heat-hardening, etc.).
  • The proposed device for a washing machine for supply of water is consequently free of burring and/or machining residues which might obstruct and/or deviate the water pathway, as occurs in the devices of the prior art in which the coupling of the shower group and the closing cover is done by welding (vibration, hot-knife, spot) with extremely long working times.
  • The proposed method for realising the device for a washing machine for supply of water of the invention is able to ensure assembly steps of the shower group and the closing cover that are extremely rapid and intuitive.
