Definitions

  • the present invention refers to a dish-washing machine comprising a washing chamber and a cabinet, said cabinet having a base and an upper part.
  • dish-washing machines with a parallelepiped base in plastic material have been realised, supporting the steel sheet cabinet and the chamber also being of steel sheet; dish-washing machines with the washing chamber completely in plastic material have also been proposed.
  • Document EP-A-0 452 287 discloses a dish-washing machine in which the washing chamber comprises a base and an upper part.
  • Document FR-A-2 371 281 discloses a dish-washing machine comprising a self-supporting washing chamber.
  • the aim of the present invention is that of solving the abovementioned problems, and to indicate a dish-washing machine that has a consistent savings in production costs, without having the drawbacks of traditional dish-washing machines.
  • the present invention has as its subject a dish-washing machine as defined in the appended claims.
  • the idea to also incorporate in the plastic base of a dish-washing machine the bottom of the washing chamber represents a practical and economical solution, mainly in union of the idea to give a metallic appearance, to the visible part of such chamber bottom (or even to the visible parts of a chamber entirely realised in plastic).
  • the traditional taste requirements of the user that takes into account the aesthetic appearance, can be satisfied conferring to the internal part of the chamber the traditional metallic appearance, as will be described in the following.
  • Figure 1 schematically represents an element in a plastic material of a dish-washing machine according to the invention, realised in a single piece, for example utilising the hot blow moulding system.
  • Such system consists in the hot extrusion of a tube in a plastic material (for example in the case of the element of figure 1 polypropylene may be utilised, possibly with the addition of glass or talc); the tube is then shaped, inside a suitable mould, by blowing air into it.
  • a plastic material for example in the case of the element of figure 1 polypropylene may be utilised, possibly with the addition of glass or talc
  • reference number 1 indicates the base of the piece, of a rectangular form; towards the bottom the base is open, so as to enable access to its interior for the assembly of hydraulic components; the piece 1 also incorporates three fixed feet; a fourth foot is provided that can be adjusted for ensuring stability.
  • Reference numbers 2a and 2b indicate two lateral support stanchions, that support the skirt and the top of the washing chamber, these being made in stainless steel and fixed to the base 1 as will be later illustrated with reference to figure 2.
  • Reference number 2c indicates a fixing point of the support for the rails of the upper basket; a similar firing point is naturally arranged on the lateral support 2a.
  • Reference number 3 indicates a vent device, in itself known, obtained together with the lateral stanchion 2a, of which it forms an integral part.
  • Reference number 4 indicates the drainage sump, incorporated with the bottom of the chamber 30 (note fig. 2), also incorporated in the base 1; said sump has a circular seat for the usual filter, that withholds the particles of residues present in the washing liquid.
  • Reference number 5 indicates a container of the water softener device, also incorporated in the bottom of the chamber 30; as will later be seen the water softener in reality is not complete.
  • Reference number 6 indicates the support of the lower rotary spraying arm of the dish-washing machine (indicated with 21 in Figure 2), also incorporated in the bottom of the chamber 30.
  • Reference number 7 indicates a rail of the lower basket, that is obtained from a band elevating from the base; a similar rail is obtained on the symmetric side (as seen in fig. 2).
  • reference number 5 indicates the salt container being part of the water softener device
  • reference number 8 indicates the bottom of the container 5, to which it is welded
  • reference number 9 indicates the cover of the same water softener device.
  • Reference number 7 indicates the rails of the lower basket, indicated with 10; reference number 11 indicates the connection and sealing system between the stainless steel skirt of the chamber, indicated with 12, and the plastic base; as can be seen, in particular in figure 3, the steel sheet that constitutes the skirt of the chamber is pinch-folded in 13, creating a supplementary edge for protection against water loss; in 14 a seal of rubber or of an equivalent material is indicated; the seal is held under pressure by suitable brackets 15 screwed to the plastic base and causing pressure on the steel sheet edge; one of fixing screws is indicated with 16.
  • FIG. 3 With reference number 23 one of the side walls of the cabinet of the machine is indicated, being a double wall; with 24 a protrusion obtained by the pinch-folding of such wall 23 is shown, that is inserted in a suitable seat 25 (fig. 1) realised on the base of the machine; the fixing between the walls 23 and base 1 is ensured by means of screws 26.
  • reference number 17 indicates the water flow that effects from drainage sump 4 in the direction of the washing pump
  • reference number 18 indicates the water flow in the direction of the drainage pump
  • reference number 19 indicates the heating resistor, that it is always submerged, being in the sump under the filter 20.
  • Reference number 21 indicates the lower rotary spraying arm.
  • the dish-washing machine is equipped with a device, of the type known, for example a pressure switch, that controls the attainable maximum level of water in the chamber; such maximum level, indicated with the letter B, is lower than the level (indicated with the letter A) of the skirt-base joint of the chamber, this ensures that the junction does not have to be watertight, but solely provided against the showers produced by the rotary spraying arms.
  • a device of the type known, for example a pressure switch, that controls the attainable maximum level of water in the chamber; such maximum level, indicated with the letter B, is lower than the level (indicated with the letter A) of the skirt-base joint of the chamber, this ensures that the junction does not have to be watertight, but solely provided against the showers produced by the rotary spraying arms.
  • Reference number 30 indicates the chamber bottom; said bottom 30, at least in its visible part, is coated with a thin foil of stainless steel sheet, that is incorporated during the hot blow-moulding operation.
  • reference number 22 indicates a plastic enbloc realised with the previously described system of hot blowing; the lateral walls and of the top are all double: thus in the cavity of the double walls sound-proofing material may be advantageously introduced, for absorbing the functional noise of the dish-washing machine.
  • the previously mentioned protrusion of the wall 23 is represented, that is inserted in the suitable seat 25 (Fig. 1) realised in the base 1.
  • the suitable seat 25 Fig. 1
  • a part of the enbloc for example the upper part 27, may be coated with a decorative foil for aesthetic reasons.
  • FIG 5 a door for traditional dish-washing machines in metal is represented; reference number 28 indicates the internal part of the door, or door lining, in stainless steel; reference number 29 indicates the external part of the door, in sheet-plate; reference number 40 indicates a control board.
  • figure 6 represents schematically in section a door realised in plastic for the dish-washing machine according to the invention
  • reference number 40 indicates the control board, the same as that of the traditional door
  • reference number 41 indicates the internal part of the door according to invention
  • reference number 42 indicates the external part of the same door.
  • the door is also realised with the same hot blowing system as previously described and with a double wall; the cavity of the door can also be filled with a foam sound-proofing material; likewise a part of the door may be coated with a decorative foil for aesthetic reasons (for example the external part) or may be treated for providing, in the previously described manner, a metallic appearance (for example the internal part).
  • reference number 1' indicates the base of the dish-washing machine, that comprises all the visible elements of the base in figures 1 and 2, with the exception of the vent hole 3;
  • reference numbers 2a', 2b' and 43 show respectively the two lateral stanchions, of reduced height compared of those visible in Figure 1, and a rear support stanchion, destined to bear the superior part of the cabinet; for such results seats and pinch-folds are provided on stanchions 2a', 2b', 43 and on the base 1' for realising the fixing and ensuring the necessary water-tightness.
  • enbloc 22' a plastic enbloc is schematically illustrated representing the superior part of the cabinet (side walls, rear wall and top) of the dish-washing machine: such enbloc 22', that it is realised with the previously described hot blowing system, incorporates in this case the skirt and top of the washing chamber.
  • the internal part of the side 23' and rear 44 walls actually constitute the skirt of the washing chamber, while the underside of the top 27' realises the top of the same chamber; naturally the part in view of the plastic chamber obtained in this manner can be covered with the previously described techniques, in order to provide a metallic appearance, as those realised traditionally in steel.
  • the external part of the lateral and rear walls and the superior part of the top realise on the contrary the exterior of the dish-washing machine, in view of the user; a part of the cabinet, for example the top 27' may be coated with a decorative covering for aesthetic reasons.
  • the enbloc 22', or the ensemble of side walls 23', the rear wall 44 and the superior plane 27' (or top) is realised with the double wall system; also in this case, therefore, in the cavity of the double walls sound-proofing, foam or similar material may be introduced in the known way for absorbing the noise generated during the functioning of the dish-washing machine.
  • Reference number 2c' finally indicates a fixing point of the support for the rails of the upper basket; a similar fixing point is naturally arranged on the left side wall 23'.
  • the lower part of the side walls 23' and of the rear wall 44 also have steps and pinch-folds, through which the fixing between the upper part and the base of the cabinet of the dish-washing machine is obtained, as already previously mentioned.
  • reference number 11' indicates a possible connection and sealing system between the upper part 22' (side walls, rear wall and top) of the cabinet, that incorporates the skirt and the top of the chamber, and the plastic base 1'; as can be seen, in the internal part of side walls 23' (and rear 44, not visible), that constitute the skirt of the chamber, a pinch-fold 45 is provided that creates a protective edge against water losses; with 46 a seal in rubber or equivalent material is indicated.
  • a further pinch-folding, of the external part of the walls, is indicated with 47; such pinch-fold determines an edge destined to cooperate with an appropriate seat (shown with 25' in Figure 7) provided on the base 1' of the machine; the fixing between the walls 23' (and 44) with the base 1' is realised by means of screws 26'.
  • the dish-washing machine according to invention allows for obtaining a drastic reduction in the number of pieces, with consequent advantages from the viewpoints of time and of production costs, transformation and assembly.
  • the base 1 has the function of at least 11 pieces of traditional dish-washing machines (even those that already utilise a base in plastic, require however at least six pieces); also the enbloc 22 (or 22'), incorporates in a single piece at least the lateral visible walls and the top of the dish-washing machine (or also the skirt and top of the washing chamber).
  • the described solution has a reduced cost of equipment, due to the adopted technology and the possibility of automating a large part of the manufacturing process.
  • vent device for the steam of the chamber could be incorporated in the base 1' or in the enbloc 22', during the previously described hot blowing operations.
