- DE 198 06 700 A1 discloses a component according to the preamble of claim 1.
- the present invention also relates to a dishwashing machine comprising an integrated component of the type mentioned above.
- Figure 1 shows an integrated component for supplying and treating water for a dishwashing machine, said component comprising a monolithic body 10 of plastics material.
- the latter comprises an approximately flat part 12 arranged in a substantially vertical manner, from a lower portion of which there protrudes an attachment 14 having a substantially parallelepiped shape.
- the term "monolithic” in the present description is intended to mean an assembly formed by two or more parts which are joined permanently to one another and are no longer separable, apart from possibly as a result of irreversible breakage.
- the monolithic body 10 is produced by welding together ( Figure 2 ) two half-parts 10a, 10b along a line which lies in a vertical plane.
- the half-part 10a, arranged at the rear with reference to Figure 2 may be a simple planar sheet, or may include elevations which, in combination with those of the half-part 10b, form the internal circuits of the component, which includes ( figures 6-9 ):
- a pump of this type brings about a flow of regenerating brine in the chamber 20, and comprises: a body in which a brine inflow conduit provided with a one-way valve and a brine outflow conduit provided with a one-way valve are defined; a solenoid having a longitudinal axis and arranged within the body; and a core controlled by the solenoid, mobile along the axis, provided with return elastic means and having an upper end associated to the body and a lower end connected to a centre portion of a membrane, whose peripheral portion is fixed to the body.
- the outflow conduit has an initial portion coaxial with the axis so that, when the pump is not active, the mouth of the initial portion is closed by the centre portion of the membrane which ensures the water-tightness in both directions between the
- the inlet opening 32 of the compartment 30 for blowing out vapours is formed ( Figures 1 and 10 ) in a protrusion 42 of the central portion of the substantially flat part 12, which has a substantially circular cross section and a substantially horizontal axis 44 and has a plurality of elastic tabs 46 on its lateral external surface.
- Each tab 46 has, in plan view, a substantially rectangular shape, is connected to the protrusion 42 only on one side 48, and has a thickness which increases gradually proceeding towards the opposite side which constitutes a free edge.
- the filler tube 28 for loading the salt is part of a protrusion 50 of the attachment 14 of the monolithic body 10, said filler tube having a substantially circular cross section and a substantially vertical axis 52 and having a plurality of elastic tabs 46 on its lateral external surface.
- the structure of these tabs 46 is substantially analogous to that of the tabs described previously in relation to the protrusion 42.
- the protrusions 42, 50 make it possible for the component to be connected directly to a washing tank 54 of the dishwashing machine, without it being necessary to use additional fixing elements, such as nuts and the like, and/or tubes, thereby facilitating the adoption of automated assembly processes.

- the possibility to conventionally use known fixing elements, such as tightening nuts and the like, for at least one of the two connections is not excluded, however.
- the tank 54 is made from metal sheet and has, in a substantially vertical side wall 56 and in a substantially horizontal bottom wall 58, a respective projection 60, within each of which provision is made of an opening 62 having a shape corresponding to that of the protrusion 42, 50 of the integrated component inserted therein.
- This insertion is made possible by the curvature of the respective elastic tabs 46, which firstly curve inwards radially and then expand radially outwards, acting as elastic holding means which prevent subsequent inadvertent removal of the component.
- a water-tight seal at the openings 62 of the tank 54 is ensured by respective O-rings 64 arranged between the internal wall of each projection 60 and a facing section of the external wall of the protrusion 42, 50.
- Both of the connections between the openings 62 of the tank 54 and the protrusions 42, 50 of the monolithic body 10 are formed with a certain degree of play, corresponding to the machining tolerances with which the openings 62 can be formed.
- the connection which involves the protrusion 42 has to allow a movement along the horizontal axis 44
- the connection which involves the protrusion 50 has to allow a movement along the vertical axis 52.
- the opening 32 is in communication with the tank 54 and can thus act as an inlet into the compartment 30 for the vapours which are generated in the tank 54 during the washing operations and should be removed.
- these vapours can be discharged later passing through the outlet opening 34 of the compartment 30. This discharge also makes it possible to dampen any pressure variations which form in the washing tank 54 due to variations in temperature.
- the chamber 20 containing ion exchange resins has an outwards opening 66 provided with a removable plug 68, also typically made of plastics material, such as to allow for the introduction or removal of said resins, as desired.
- the plug 68 has a plastic coupling advantageously with a degree of play of less than 0.2 mm in the part in contact with the resins and a coupling on the wall of the opening 66 which prevents water escaping owing to a plastic-on-plastic contact. If appropriate, provision may be made for a sealing gasket to be present between the wall of the opening 66 and the plug 68.
- the plug 68 may be formed in one piece with one of the two half-parts 10a, 10b, to which it is connected by a flap or similar holding means which allow for the opening/closing movement with respect to the opening 66, in any case holding the plug on the body 10.
- This arrangement is extremely advantageous because it makes it possible to hydraulically test the component before the resins are introduced into the chamber 20. As a result, only the parts which have passed the test are loaded with the resins, whereas those which are rejected can be passed on directly for the recycling operations. Analogously, at the end of the service life of the component, it is possible to remove the plug 68 and empty the chamber 20 of the resins, such that in this case, too, the component from which the latter have been removed can easily be recycled.
- the mains water is supplied from the inlet conduit 16 into the chamber 20, where it is decalcified by the ion exchange resins (cf. Figures 6 and 7 ).
- the decalcified water exits from the top of the chamber 20 through the conduit 22, and firstly passes through the air break section 24, which does not cause a loss of pressure owing to its position downstream of the chamber 20.
- the decalcified water enters ( Figures 10 and 12 ) into a conduit 53, which issues, in a manner known per se, into the washing tank 54 through a passage formed between an arch of the circumferential wall of the filler tube 28 and the wall of the protrusion 50 arranged coaxially outside it.
- the closed-circuit regeneration method described above has a number of advantages. On the one hand, it does not involve additional consumption of water, since only that which is initially present in the chamber 20 is used, nor does it require devices for measuring and collecting the quantity of water intended to form the brine. Indeed, from that described above it results that the chamber 20 for containing ion exchange resins also acts as a container for the water intended to form the brine, thereby making it possible to do without a vessel intended specifically for that function, with a resultant simplification of the structure of the integrated component. In addition, the salt reservoir 26 is not placed under pressure, and therefore the brine cannot penetrate into the washing tank 54, even if the plug 29 of the filler tube 28 is not sealed. On account of this, the regeneration can also be carried out during any desired operating stage of the dishwashing machine, with a reduction in the overall time required by the respective washing cycle.

Figure 1 shows an integrated component for supplying and treating water for a dishwashing machine, said component comprising amonolithic body 10 of plastics material. The latter comprises an approximatelyflat part 12 arranged in a substantially vertical manner, from a lower portion of which there protrudes anattachment 14 having a substantially parallelepiped shape. The term "monolithic" in the present description is intended to mean an assembly formed by two or more parts which are joined permanently to one another and are no longer separable, apart from possibly as a result of irreversible breakage. - Advantageously, the
monolithic body 10 is produced by welding together (Figure 2 ) two half-parts part 10a, arranged at the rear with reference toFigure 2 , may be a simple planar sheet, or may include elevations which, in combination with those of the half-part 10b, form the internal circuits of the component, which includes (figures 6-9 ): - an
inlet conduit 16 for water, on which aflowmeter 18 is optionally positioned; - a
chamber 20 containing substances with water-softening properties, in particular ion exchange resins, into which theinlet conduit 16 opens out and out of which there leads anoutlet conduit 22 having anair break 24 in its initial section; - a salt-containing
reservoir 26, positioned in theattachment 14, that is in the lowest portion of thebody 10, and having afiller tube 28 for loading the salt, which is provided with a plug 29 (shown for greater clarity only inFigures 12 and13 ); - a
compartment 30 for blowing out vapours, having an inlet opening 32 and an outlet opening 34; - a
conduit 36 for supplying water to thereservoir 26 so as to produce a brine for regenerating substances with water-softening properties; and - a
conduit 38 for connecting thereservoir 26 to thechamber 20, on which there are positioned means for controlling the flow of the brine, such as apump 40. - By way of example, the latter may be of the type described in the Italian patent application
102015000025500 chamber 20, and comprises: a body in which a brine inflow conduit provided with a one-way valve and a brine outflow conduit provided with a one-way valve are defined; a solenoid having a longitudinal axis and arranged within the body; and a core controlled by the solenoid, mobile along the axis, provided with return elastic means and having an upper end associated to the body and a lower end connected to a centre portion of a membrane, whose peripheral portion is fixed to the body. The outflow conduit has an initial portion coaxial with the axis so that, when the pump is not active, the mouth of the initial portion is closed by the centre portion of the membrane which ensures the water-tightness in both directions between the inflow and outflow conduits. - The inlet opening 32 of the
compartment 30 for blowing out vapours is formed (Figures 1 and10 ) in aprotrusion 42 of the central portion of the substantiallyflat part 12, which has a substantially circular cross section and a substantiallyhorizontal axis 44 and has a plurality ofelastic tabs 46 on its lateral external surface. Eachtab 46 has, in plan view, a substantially rectangular shape, is connected to theprotrusion 42 only on oneside 48, and has a thickness which increases gradually proceeding towards the opposite side which constitutes a free edge. On the other hand, thefiller tube 28 for loading the salt is part of aprotrusion 50 of theattachment 14 of themonolithic body 10, said filler tube having a substantially circular cross section and a substantiallyvertical axis 52 and having a plurality ofelastic tabs 46 on its lateral external surface. The structure of thesetabs 46 is substantially analogous to that of the tabs described previously in relation to theprotrusion 42. - As is shown in
Figures 3-5 , theprotrusions washing tank 54 of the dishwashing machine, without it being necessary to use additional fixing elements, such as nuts and the like, and/or tubes, thereby facilitating the adoption of automated assembly processes. In particular, first the protrusion 50 (Figure 4 ) and then the protrusion 42 (Figure 5 ) are connected. The possibility to conventionally use known fixing elements, such as tightening nuts and the like, for at least one of the two connections is not excluded, however. - The
tank 54 is made from metal sheet and has, in a substantiallyvertical side wall 56 and in a substantiallyhorizontal bottom wall 58, arespective projection 60, within each of which provision is made of anopening 62 having a shape corresponding to that of theprotrusion elastic tabs 46, which firstly curve inwards radially and then expand radially outwards, acting as elastic holding means which prevent subsequent inadvertent removal of the component. A water-tight seal at theopenings 62 of thetank 54 is ensured by respective O-rings 64 arranged between the internal wall of eachprojection 60 and a facing section of the external wall of theprotrusion - Once the component has been connected to the
washing tank 54 at thevertical wall 56 and at thehorizontal wall 58, the weight of said component is supported essentially by theprotrusion 42 of the central portion of the substantiallyflat part 12. - Both of the connections between the
openings 62 of thetank 54 and theprotrusions monolithic body 10 are formed with a certain degree of play, corresponding to the machining tolerances with which theopenings 62 can be formed. In particular, the connection which involves theprotrusion 42 has to allow a movement along thehorizontal axis 44, whereas the connection which involves theprotrusion 50 has to allow a movement along thevertical axis 52. - The presence of a respective connection on each of the two
orthogonal walls tank 54 intrinsically stable, and therefore the presence of elastic holding means, such as thetabs 46, on theprotrusions protrusions tabs 46 and the component is kept assembled on thetank 54 owing to the interference which exists between the respectively facing parts and the interposed O-rings 64. - At the end of the assembly process, the
opening 32 is in communication with thetank 54 and can thus act as an inlet into thecompartment 30 for the vapours which are generated in thetank 54 during the washing operations and should be removed. In a manner known per se, these vapours can be discharged later passing through the outlet opening 34 of thecompartment 30. This discharge also makes it possible to dampen any pressure variations which form in thewashing tank 54 due to variations in temperature. - At the top (
Figure 1 ), thechamber 20 containing ion exchange resins has an outwardsopening 66 provided with aremovable plug 68, also typically made of plastics material, such as to allow for the introduction or removal of said resins, as desired. Theplug 68 has a plastic coupling advantageously with a degree of play of less than 0.2 mm in the part in contact with the resins and a coupling on the wall of the opening 66 which prevents water escaping owing to a plastic-on-plastic contact. If appropriate, provision may be made for a sealing gasket to be present between the wall of the opening 66 and theplug 68. In embodiments of the invention which are not shown, theplug 68 may be formed in one piece with one of the two half-parts body 10. - This arrangement is extremely advantageous because it makes it possible to hydraulically test the component before the resins are introduced into the
chamber 20. As a result, only the parts which have passed the test are loaded with the resins, whereas those which are rejected can be passed on directly for the recycling operations. Analogously, at the end of the service life of the component, it is possible to remove theplug 68 and empty thechamber 20 of the resins, such that in this case, too, the component from which the latter have been removed can easily be recycled. - During normal operation of the component, the mains water is supplied from the
inlet conduit 16 into thechamber 20, where it is decalcified by the ion exchange resins (cf.Figures 6 and 7 ). The decalcified water exits from the top of thechamber 20 through theconduit 22, and firstly passes through theair break section 24, which does not cause a loss of pressure owing to its position downstream of thechamber 20. Then, the decalcified water enters (Figures 10 and12 ) into aconduit 53, which issues, in a manner known per se, into thewashing tank 54 through a passage formed between an arch of the circumferential wall of thefiller tube 28 and the wall of theprotrusion 50 arranged coaxially outside it. - When the ion exchange resins are exhausted, it is necessary to regenerate them. For this purpose (cf.
Figures 8 and 9 ), it is sufficient to activate a single control device, that is thepump 40 positioned on theconduit 38, which forces the water remaining in thechamber 20 to enter into thesupply conduit 36 of thesalt reservoir 26, in which it produces a brine. The latter enters into the connectingconduit 38 and is sucked up by thepump 40 into thechamber 20, where it regenerates the ion exchange resins. - The closed-circuit regeneration method described above has a number of advantages. On the one hand, it does not involve additional consumption of water, since only that which is initially present in the
chamber 20 is used, nor does it require devices for measuring and collecting the quantity of water intended to form the brine. Indeed, from that described above it results that thechamber 20 for containing ion exchange resins also acts as a container for the water intended to form the brine, thereby making it possible to do without a vessel intended specifically for that function, with a resultant simplification of the structure of the integrated component. In addition, thesalt reservoir 26 is not placed under pressure, and therefore the brine cannot penetrate into thewashing tank 54, even if theplug 29 of thefiller tube 28 is not sealed. On account of this, the regeneration can also be carried out during any desired operating stage of the dishwashing machine, with a reduction in the overall time required by the respective washing cycle. - Clearly, without departing from the principle of the invention, the constructional details and the embodiments may be greatly varied with respect to that described purely by way of example, without thereby departing from the scope of the invention as defined in the accompanying claims.
