In this manner, thefirst electromagnet 38 is able to displace with itsmovable core 40 both thelevers 42 and 50 simultaneously from the one to the other one of their two operative positions, respectively from the first rest position thereof, illustrated by the Fig. 3, in which thelever 42 has its shapedend 46 engaging therecess 47, thereby keeping thecontainer 15 into its engaged condition in which the powdered detergent contained therein may be distributed by a timed controlled operation into the tank, in the manner hereinafter described, while in turn the lever 50 isn't pushed downward by the overhanginglever 42 and therefore keeps the overturninglid 32 at a closed condition thereof, engaging thecontainer 18, thereby preventing it from being opened, to the operation position thereof, not evident, in which thelever 42 is rotated around itsfulcrum point 43, thereby disengaging its shapedend 46 from therecess 47 and therefore permitting thecontainer 15 to be opened and filled with the powdered detergent in the manner hereinafter described, while in turn the lever 50 is pushed downward by the consequent lowering of the lowerfree end 48 of thevertical arm 44 of thelever 42, so that such lever 50 by rotating in the direction indicated by the arrow A causes the displacement of the overturninglid 32 of thecontainer 18 in the released position thereof, in which it is opened and therefore permits the detergent contained therein to be distributed in the tank. Besides, thesecond electromagnet 39 is arranged at an inclined position thereof and connected to the control means for the liquidadditive detergent container 17, which are constituted preferably by a conventional valve (not shown), in such a way that to actuate the same at an opened and closed position thereof for determining or preventing the distribution of such liquid additive detergents into the tank. Finally, afurther lever 52 is housed on the back side of thecontainer 15, at a position below thecontainer 15 and co-operating therewith, which lever is interconnected by means of aflexible cable 53 with thelock 54 of thedoor 11 of the dish-washing machine, and is pivoted rotatable thereon in such a way as to be actuated by thecontainer 15 in two different operative positions thereof, respectively from a first position in which it pulls theflexible cable 53 downward, in the direction of the arrow B of the Fig. 4, when thecontainer 15 is housed on its seat and engaged by thelever 42, in which condition acontrol mechanism 55 of conventional kind provided on the free end ofsuch cable 53 does not affect saidlock 54 and therefore any opening and closing operation of said door by means of said lock is permitted, to a second operative position thereof in which thelever 52 displaces the cable upward, in the direction of the arrow C of Fig. 4, when thecontainer 15 is released by thelever 42 and therefore moved to its opened position, in which condition thecontrol mechanism 55 of thecable 53 affects thelock 54, thereby preventing thedoor 11 from being closed. - By referring now to the Figs. 5, 6 and 7, shown therein is the
container 15 of the present integrated dispenser in three different operative conditions thereof, in which it is noted that such container and to this aim it includes anadditional container 151 inside it having dimensions slightly lower, which defines ahollow space 56 between it and the surrounding walls of thecontainer 15, for circulating a flow of cooling air generated by therotor 36 or by natural convection, and adapted to maintain the detergent within the pre-established temperature boundary which are compatible for the use thereof.Such container 151 is additionally provided with adequate means for locking it into itscontainer 15, and also at least aninner valve member 57 of per se known kind, acting on thelower drainage hole 58 thereof and operable through theshaped end 46 of thelever 42, which can be coupled thereto, in a manner to close or open such hole, in order to prevent or permit the detergent distribution depending on the displacement of thelever 42 into different positions thereof, as well as afiltering element 59. In the Figs. 5 and 6 is shown thecontainer 15 at the closed position thereof, in which condition theadditional container 151 is arranged for distributing the detergent into the tank, through the automatic distributing andmetering system 34 which in this case communicates with both thedrainage hole 58 of thecontainer 151 and the tank. - In Fig. 5, in particular, it is noted that the automatic distributing and
metering system 34 is operated on the opened position thereof, in which thecontainer 151 is put into communication with the tank through theflexible conduit 60 made of resilient material, which is affected by a separated pressingmember 61 adapted to be pressed or not pressed against saidflexible conduit 60. - In this case, the
pressing member 61 is made rotatable with a limited angle of rotation, and maintained at this rest position by asuitable compression spring 62, as well as operated by a shaft 63 (evident in the Fig. 3) orthogonal to theflexible conduit 60 and actuated in rotation by thepneumatic actuator 37 under the control operation of the machine timer, in the present example such pressing member being not compressed against theflexible conduit 60. - Under these circumstances, however, the detergent isn't distributed into the tank, since the
drainage hole 58 of thecontainer 151 is closed by thevalve member 57 and such distribution occurs as soon as said valve means is operated into its opened position, thereby by releasing thedrainage hole 58 and permitting the detergent to pass through theflexible conduit 60. On the contrary, in the Fig. 6 it is noted that thepressing member 61 has been actuated by thepneumatic actuator 37 into its operative position, compressed against theflexible condit 60, in which also thespring 62 is compressed, with consequent squeezing of said flexible conduit and interruption of the connection between thecontainer 151 and the tank, in which condition the detergent distribution into the same tank is prevented. - Finally, in the Fig. 7 it is noted that in this case the
container 15 is displaced into the opened position thereof, being extracted forward and rotated around its lower hinged position, in which condition the shapedend 46 of thelever 42 is disengaged from therecess 47 of the same container, with consequent access to theadditional container 151 for filling it with the powdered detergent or for any possible cleaning or maintenance operation thereof, in which circumstance the communication between thedrainage hole 58 of said additional container and theflexible conduit 60 is interrupted. By examining now the Figs. 8-13, it is shown schematically theoverturning lid 32 for the access to the detergentsingle dose container 18, which is represented into three different operative positions thereof. - This lid, in particular, is provided at its inner surface with a hollow 64 and a lower projected
hook 65, turned toward the inside of thecontainer 18 and adapted to co-operate both with acorrespondent counter-hook 66, projected from abent arm 67 fixed to thestud 51 acting as a fulcrum of the lever 50 and operable in rotation by such lever, which in turn is operated by as already described by thefirst electromagnet 38, in such a way thatsuch counter-hook 66 may be actuated into three different positions thereof corresponding to such operative positions of the overturning lid. - In the Figs. 8 and 9, in particular, it is noted that the
lid 32 is closed in front of thecontainer 18, in which condition thecounter-hook 66 has been displaced upward by the rotation of the lever 50, so as to engage the hollow 64 only and to be disengaged from thehook 65. - Then, at this operative position of the
lid 32, it is kept engaged and permits thecontainer 18 to be filled with detergent, and may be disengaged manually therefrom for any possible introduction of additional detergent therein. - In the Figs. 10 and 11 it is noted that the
counter-hook 66 has been displaced by the rotation of the lever 50 at a position intermediate between the hollow 64 and thehook 65, in which it is disengaged from both and therefore permits thelid 32 to be opened and the dose of detergent to be distributed from thecontainer 18 toward the machine tank. - Finally, in the Figs. 12 and 13 it is noted that the
counter-hook 66 has been displaced downward by the rotation of the lever 50, so as to engage thehook 65 only and to be disengaged from the hollow 64. - Then, at this operative position of the
lid 32, it remains engaged permanently and cannot be opened automatically therefrom, thereby excluding the possibility to add still detergent in thecontainer 18 during the carrying out of each washing cycle, with subsequent lid unlocking which is made possible by displacing thecounter-hook 66 again into its other operative positions in the same manners as described above. In the Figs. 14-16 it is now illustrated another constructive component part of the present integrated dispenser, which permits a simple and quick assembling and disassembling thereof with respect to the dish-washing machine. This component part is substantially formed by a thinperipheral frame 68 having the same shape and dimensions slightly larger than the box-like envelope 13 of said integrateddispenser 10, for the accommodation around the entire peripheral outline of said box-like envelope thereof, said frame being provided with two half-portions insertion tongues 71 which can be engaged around said box-like envelope, whose ends are provided with respective foldededges screws 76 or the like after that said half-portions have been fitted around the box-like envelope 13, at the condition in which suchperipheral frame 68 holds in its seat also theperipheral sealing gasket 24 of the container 15 (see Figs. 15 and 16). - By examining now the remaining Figures 17-22, shown therein are different possible embodiments of the present integrated dispenser, obtained by modifying adequately the reciprocal arrangement of the different component parts of the same dispenser. In the Figs. 17 and 18 it is noted that the arrangement of the different component parts is practically the same of the Fig. 2, except that in this case the
container 15 is shaped in a reversed mode and both theindicator 30 and thedischarge hole 31 of the liquidadditive detergent container 17 are aligned with each other in a vertical direction instead of horizontal one, as from the Fig. 2. In the Figs. 19, 20 and 21 it is noted that thecontainer 15 is housed almost at the same preceding position thereof, however in this case it has different shape (square) with dimensions slightly smaller and itshandle 27 is projected laterally at the left-hand side instead of upwardly, and is hinged laterally in its accommodation space, while in turn the liquidadditive detergent 17 is arranged near the upper edge of the box-like envelope 13, laterally at the left-hand side of thecontainer 15, and at the position below it there are arranged aligned vertically both thecorresponding indicator 30 and thedischarge hole 31, and finally the distributing andmetering system 34 is arranged below thecontainer 18 and associatedlid 32, which are held at the same preceding position thereof. - Finally, in the Fig. 22 it is noted that the
container 15 is practically identical to that of the Figs. 19-21 and with respect thereto it is displaced at the left-hand side, so as itshandle 27 be slightly projected beyond the left-hand side peripheral edge of the same container, while in turn the liquidadditive detergent container 17 is arranged between thecontainer 15 and thecontainer 18 withrelative lid 32, which are held together with the distributing andmetering system 34 at the same position of the preceding figures 19-21, and at a position below thecontainer 17 there are arranged aligned vertically saidindicator 30 anddischarge hole 31. Of course, it is also possible to arrange these component parts in different manners and combinations with respect to those described by way of example only, as well as it is also possible to operate these component parts with different criteria with respect to those previously described, provided that it is always obtained an identical operation of the present integrated dispenser, thereby without departing from the protection field of the invention.
