Powdered and liquid detergent and additive detergent integrated dispenser for wasching machines, in particular household dish-washing machines

Abstract: Powdered and liquid detergent and additive detergent integrated dispenser for household dish-washing machines, comprising a box-like envelope (13) made of molded plastic material, in which there are embodied a first container (15) having long duration storage capacity with powdered detergent at such amounts as to perform different washing cycles, a second container (17) for liquid additive detergents like the brightness conditioner, and a third container (18) for powdered or liquid detergent, with a dose for a single washing cycle. The dispenser is arranged for being filled with detergents and additive detergents and for distributing them automatically during each selected washing cycle.

Description: The invention refers to a powdered and liquid detergent and additive detergent integrated dispenser for washing machines, in particular household dish-washing machines, adapted to hold metered amounts of these detergent materials, such as to permit that both a plurality of washing cycles and only one washing cycle be performed, as well as such detergent materials to be delivered to the tank of these washing machines at pre-established moments of the cycle. From EP-A-0457137 is known a dispenser in clothes and dish washing machines, having two compartments for storage of powder detergent and liquid rinsing aid which are provided with a respective movable lid, which when opened permits the access to the respective compartment for filling it with the correspondent detergent and rinsing aid. The powder detergent and the rinsing aid are discharged in the machine tank respectively by opening the lid and by actuating a valve provided in the rinsing aid comparment, and to this aim the lid and the valve are associated to a respective magnet co-operating with correspondent lamellar elements made of an iron-nickel alloy heated by a thermistor or a PTC heater, which elements maintain their magnetic properties until they are heated up to the Curie point thereof. In this way, when the lamellar elements are heated below their Curie point, they are attracted by the magnet so that the lid is kept closed and the valve shut off, thereby preventing the detergent and rinsing aid from being discharged from the respective compartment. On the contrary, when such lamellar elements are heated up to their Curie point, they become nonmagnetic and are not more attracted by the magnet, so as the lid and the valve are opened automatically and the detergent and rinsing aid are respectively discharged from the correspondent compartment in the machine tank, for performing a single washing cycle. From EP-A-0554676 is known a dispenser of detergent and rinse aid in washing machines, comprising a feedbox that receives the detergent from a reservoir and delivers it into a metering chamber, which is opened and closed by a movable lid and adapted to meter such detergent amounts for different washing cycles. This lid is provided with a flexible element and dimensioned and shaped in a manner to prevent clots and moist detergent powder from being formed and built up on the lower edge of the metering chamber, so as to permit the detergent to be discharged effectively from the metering chamber in the machine tank for performing the respective washing cycle. This prior art forms the preamble of independent claim 1. From EP-A-0602572 is known a dispenser device for liquid and powder agents for a dish-washing machine, comprising a first and a second delivery device for introducing the washing agents in the machine tank at distinct moments and/or washing phases, which devices are actuated by particular mechanisms independently from each other, for performing a single washing cycle. From DE-U-8602245 is known a dispenser for detergent and brightness conditioner provided with two compartments closed by a respective lid, actuated by correspondent mechanisms independently from each other, for discharging the detergent for a single washing cycle and the brightness conditioner for several washing cycles. From US-A-5211188 is known an additive dispenser provided with a container for rinse aid and detergent for a dish-washing machine, formed in the inner wall of the machine door and a cover movable between a position closing the container and a position exposing the container and discharging the rinse aid and the detergent into the machine tank, for performing a single washing cycle. The present invention refers to a detergent and additive detergent dispenser for washing machines, which is made with a holding capacity of such detergent materials at such amounts to be sufficient to perform various cycles, on the contrary of the dispensers disclosed by EP-A-0457137, EP-A-0602 572 and US-A-5211188 which are holding detergent materials for performing a single washing cycle only, and which is made in construction and operation in a manner different than those disclosed by EP-A-0554676 and DE-U-8602245, which are holding detergent materials for performing various cycles too. This dispenser is made as described on the characterizing part of claim 1.

In the Figures referred to, it is schematically represented an integrated dispenser 10 for powdered and liquid detergents and additive detergents for washing machines, in particular household dish-washing machines, adapted to hold such detergent materials and to deliver them into the tank of these machines at determined moments of each selected washing cycle. This integrated dispenser, which is formed by the component parts which will be described in detail in the Fig. 2, is advantageously fitted on the upper inner surface of the door 11 of the dish-washing machine 12, which door as usual is hinged frontally overturning on the same machine, and in the present case it is represented partially opened, in order to permit the access to such integrated dispenser 10 for filling it with the needed detergent materials. In the Fig. 2 it is now represented the dispenser 10, which is integrally made preferably with molded plastic material and comprises a box-like envelope 13 of parallelepiped form, or other suitable form, in which different rooms are provided on its front wall 14, for housing respectively a container 15 having a long duration storage capacity, for the introduction of powdered detergent through an upper cap 16 therein, at such amounts as to allow a plurality of washing cycles to be performed in the machine, a container 17 for liquid additive detergents like the brightness conditioner, and at least a container 18 for the powdered or liquid detergent, at such amount as to allow a single washing cycle to be performed. In particular, the container 15 with long duration storage capacity is advantageously shaped with an upper surface 19 and a lower one 20 having semicircular form and side surfaces 21 and 22 having rectilinear form, and is also housed in the correspondent room 23 of the box-like envelope 13, in such a way as to be hinged at the lower side of the same room, in order to be able to be displaced from an extracted position evident from the Fig. 2, for being filled with detergent through the cap 16, to a position inserted into said room, in which it enters the box-like envelope for a determinate depth thereof and its front surface flushes with the front wall 14, for the metered automatic delivery of such detergent into the machine tank on each washing cycle. Besides, this container 15 is provided with a peripheral outer gasket 24 (evident from the Figs. 5-7), adapted to be sealed against the correspondent peripheral edge 25 of the room 23 at the inserted position thereof into the container, for the reasons set forth below, which sealing is also made more effective thanks to the particular semicircular form of both the container upper wall 19 and lower one 20. Of course, the container may be made also with a different form that that described solely by way of example, by allowing always to perform the same functions thereof. This container 15 is provided additionally advantageously with at least a front opening 26 too, which is closed by transparent material, acting as indicator of the powdered detergent filling level into the same container, and accordingly marked with indication marks for the higher and lower detergent filling level into the container, as well as a projected handle 27, which in this case is provided on the upper side thereof, and can be grasped by the user in order to displace the same container into the above described two operative positions thereof, which handle is housed on a correspondent front recess 28 of the front wall 14 at the inserted position of said container. In turn, the liquid additive detergent container 17 is provided, as usual, with a removable front access cap 29 for the introduction of the liquid additive detergents therein, at least an indicator 30 for its filling level with such liquid additive detergents, made of adequate transparent material, a hole 31 for discharging the liquid additive detergents in the tank, which may be open and closed by means of per se known control means, not shown, while the container 18 is provided with an access lid 32 overturning as evident in the Figure, and movable by the machine timer from the container closed position, at the filled condition with detergents thereof, to this open position for delivering a single dose of detergent, against the action of a torsion spring 33 associated with said lid. The Figs. 8-13 will show better this lid. Finally, the present integrated dispenser 10 also comprises a powdered detergent automatic distributing and metering system, marked with the reference numeral 34, which communicates with the inside of container 15 with long duration storage capacity, and adapted to transer automatically the detergent form the same container toward the tank, which system in the present case is arranged below the container 15 and forms also the preamble of independent claim 1. Advantageously, a peripheral recess 35 is provided around the distributing and metering system 34 in the front wall 14 of the box-like envelope 13, in order to collect and discharge adequately into the tank any condensate and dripping from the inside of the same container. By examining now the Fig. 3, in which the back side of the container 15 with long duration storage capacity is shown, it is noted that a rotor 36 and a pneumatic actuator 37 are housed therein, which are adapted respectively to generate compressed air for the detergent distribution as well as to act on the above cited distributing and metering system 34, in order to operate this latter, so as to distribute and introduce through it metered amounts of powdered detergent from the container 15 toward the machine tank, by means of control of the timer during each washing cycle. Moreover, a first and a second electromagnet 38 and 39 or the like are also housed on the back side of the container 15, and connected in operation in the electric circuit of the machine and controlled by the timer thereof, of which the first electromagnet 38 is arranged adjacent the upper edge of the container 15, in such a way that its movable vertical core 40 interacts with a short horizontal arm 41 of a lever 42 pivoted on a bracket 43, fixed at the back and upper side of the container 15, which lever is provided with a vertical arm 44 joined to such horizontal arm and another horizontal extended arm 45, joined orthogonally to said vertical arm 44 and having its shaped end 46 entering a correspondent recess 47 provided on the upper side of the container 15. In turn, the lower free end 48 of the vertical arm 44 of the lever 42 is housed on the free end of a rectilinear arm 49 of another lever 50 situated below it, which is pivoted at its other end on a stud 51 fixed below the first electromagnet 38 and connected to the overturning lid 32 of the container 18 for the single dose of powdered or liquid detergent, in such a way that such lever 50 can be rotated limitedly around this fulcrum point, against the action of a torsion spring (not shown) wound around the stud 51 and urging the same lever toward its rest position of the Fig. 3, by causing at the same time the lid to be displaced on different operative positions thereof, which will be described in detail in Figs. 8-13. In this manner, the first electromagnet 38 is able to displace with its movable core 40 both the levers 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 the lever 42 has its shaped end 46 engaging the recess 47, thereby keeping the container 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 overhanging lever 42 and therefore keeps the overturning lid 32 at a closed condition thereof, engaging the container 18, thereby preventing it from being opened, to the operation position thereof, not evident, in which the lever 42 is rotated around its fulcrum point 43, thereby disengaging its shaped end 46 from the recess 47 and therefore permitting the container 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 lower free end 48 of the vertical arm 44 of the lever 42, so that such lever 50 by rotating in the direction indicated by the arrow A causes the displacement of the overturning lid 32 of the container 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, the second electromagnet 39 is arranged at an inclined position thereof and connected to the control means for the liquid additive 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, a further lever 52 is housed on the back side of the container 15, at a position below the container 15 and co-operating therewith, which lever is interconnected by means of a flexible cable 53 with the lock 54 of the door 11 of the dish-washing machine, and is pivoted rotatable thereon in such a way as to be actuated by the container 15 in two different operative positions thereof, respectively from a first position in which it pulls the flexible cable 53 downward, in the direction of the arrow B of the Fig. 4, when the container 15 is housed on its seat and engaged by the lever 42, in which condition a control mechanism 55 of conventional kind provided on the free end of such cable 53 does not affect said lock 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 the lever 52 displaces the cable upward, in the direction of the arrow C of Fig. 4, when the container 15 is released by the lever 42 and therefore moved to its opened position, in which condition the control mechanism 55 of the cable 53 affects the lock 54, thereby preventing the door 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 an additional container 151 inside it having dimensions slightly lower, which defines a hollow space 56 between it and the surrounding walls of the container 15, for circulating a flow of cooling air generated by the rotor 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 its container 15, and also at least an inner valve member 57 of per se known kind, acting on the lower drainage hole 58 thereof and operable through the shaped end 46 of the lever 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 the lever 42 into different positions thereof, as well as a filtering element 59. In the Figs. 5 and 6 is shown the container 15 at the closed position thereof, in which condition the additional container 151 is arranged for distributing the detergent into the tank, through the automatic distributing and metering system 34 which in this case communicates with both the drainage hole 58 of the container 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 the container 151 is put into communication with the tank through the flexible conduit 60 made of resilient material, which is affected by a separated pressing member 61 adapted to be pressed or not pressed against said flexible 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 a suitable compression spring 62, as well as operated by a shaft 63 (evident in the Fig. 3) orthogonal to the flexible conduit 60 and actuated in rotation by the pneumatic actuator 37 under the control operation of the machine timer, in the present example such pressing member being not compressed against the flexible conduit 60. Under these circumstances, however, the detergent isn't distributed into the tank, since the drainage hole 58 of the container 151 is closed by the valve member 57 and such distribution occurs as soon as said valve means is operated into its opened position, thereby by releasing the drainage hole 58 and permitting the detergent to pass through the flexible conduit 60. On the contrary, in the Fig. 6 it is noted that the pressing member 61 has been actuated by the pneumatic actuator 37 into its operative position, compressed against the flexible condit 60, in which also the spring 62 is compressed, with consequent squeezing of said flexible conduit and interruption of the connection between the container 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 shaped end 46 of the lever 42 is disengaged from the recess 47 of the same container, with consequent access to the additional container 151 for filling it with the powdered detergent or for any possible cleaning or maintenance operation thereof, in which circumstance the communication between the drainage hole 58 of said additional container and the flexible conduit 60 is interrupted. By examining now the Figs. 8-13, it is shown schematically the overturning lid 32 for the access to the detergent single 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 the container 18 and adapted to co-operate both with a correspondent counter-hook 66, projected from a bent arm 67 fixed to the stud 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 the first electromagnet 38, in such a way that such 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 the container 18, in which condition the counter-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 the hook 65. Then, at this operative position of the lid 32, it is kept engaged and permits the container 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 the hook 65, in which it is disengaged from both and therefore permits the lid 32 to be opened and the dose of detergent to be distributed from the container 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 the hook 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 the container 18 during the carrying out of each washing cycle, with subsequent lid unlocking which is made possible by displacing the counter-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 thin peripheral frame 68 having the same shape and dimensions slightly larger than the box-like envelope 13 of said integrated dispenser 10, for the accommodation around the entire peripheral outline of said box-like envelope thereof, said frame being provided with two half-portions 69 and 70 identical and symmetrical to each other, having a plurality of insertion tongues 71 which can be engaged around said box-like envelope, whose ends are provided with respective folded edges 72, 73 and 74, 75 turned toward each other and matching to each other, as well as adapted to be joined reciprocally by means of screws 76 or the like after that said half-portions have been fitted around the box-like envelope 13, at the condition in which such peripheral frame 68 holds in its seat also the peripheral 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 the indicator 30 and the discharge hole 31 of the liquid additive 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 the container 15 is housed almost at the same preceding position thereof, however in this case it has different shape (square) with dimensions slightly smaller and its handle 27 is projected laterally at the left-hand side instead of upwardly, and is hinged laterally in its accommodation space, while in turn the liquid additive detergent 17 is arranged near the upper edge of the box-like envelope 13, laterally at the left-hand side of the container 15, and at the position below it there are arranged aligned vertically both the corresponding indicator 30 and the discharge hole 31, and finally the distributing and metering system 34 is arranged below the container 18 and associated lid 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 its handle 27 be slightly projected beyond the left-hand side peripheral edge of the same container, while in turn the liquid additive detergent container 17 is arranged between the container 15 and the container 18 with relative lid 32, which are held together with the distributing and metering system 34 at the same position of the preceding figures 19-21, and at a position below the container 17 there are arranged aligned vertically said indicator 30 and discharge 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.
