    Description


    [0001] The present invention relates to a laundry washing machine dispenser for detergent products or similar.

    [0002] The detergent dispenser of front-loading laundry washing machines normally comprises a drawer housed in the front wall of the machine and divided internally into compartments, at least one of which is filled manually with a given amount of a respective product before each wash.

    [0003] To avoid filling the detergent compartments manually before each wash, and at the same time dispense the detergent more accurately, laundry washing machines have been designed in which the conventional drawer dispenser is replaced with compartments for one or more cartridges, each of which contains a number of measures of a respective detergent, and is connected to a hydraulic circuit of the machine to release a measured quantity of detergent at each wash according to the selected wash program.

    [0004] Laundry washing machines of the type described,

    [0005] WO-A-8806199 discloses a loading apparatus for holding and dispensing a washing additive such as a cleansing agent. The loading apparatus includes a receptacle in which there is a plurality of compartments each for receiving a discrete portion of washing additive in the form of blocks consisting of, or containing, a given amount of cleansing agent. The compartments are at least partially defined by partitions forming part of a body which is movable to bring each portion adjacent to an opening provided in the receptacle. The portions then pass through the opening to be dispensed, preferably under force of gravity. The blocks could be replaced by refillable cassettes which are adapted to remain in the loader, even when over the above mentioned opening, while allowing their contents to pour out through the opening in the base when required.

    [0006] Document EP-A1-2152950, which is prior art according to Art. 54(3) EPC, discloses an automatically controlled washing machine with a drawer, which is accessible from the front, with at least one chamber for a hand-metered addition of a washing powder dose or washing liquid dose, said drawer further comprises at least one storage container, which is mounted in the upper machine space behind the chambers of the drawer, for storing liquid or gel-like washing agent and with a respective device for automatic metering of each stored washing agent, and with at least one device for receiving a transportable container, which comprises several doses, of liquid or gel-like washing agent.

    [0007] Laundry washing machines of the type described, however, have met with little success on the home market, on account of various drawbacks, which make them awkward to use and not very versatile. Foremost of these are the impossibility of loading products manually in the usual way, and the difficulty encountered in changing or filling the cartridges, on account of the cartridge compartments normally being located in poorly accessible parts of the machine, e.g. in the base or at the back of the machine, or, in some cases, in devices actually outside the machine itself.

    [0008] It is an object of the present invention to provide a laundry washing machine dispenser for detergent products, softeners or fresheners, designed to permit both manual loading of detergents at each wash, and automatic loading using long-term-release cartridges, and which at the same time is easy to use and cheap to produce.

    [0009] According to the present invention, there is provided a laundry washing machine dispenser for detergent products, softneners or fresheners as claimed in Claim 1 and, preferably, in any one of the Claims depending directly or indirectly on Claim 1.

    [0010] A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:

    Figure 1 shows a laundry washing machine featuring a preferred embodiment of the dispenser according to the present invention;

    Figure 2 shows the Figure 1 dispenser in a different operating configuration;

    Figure 3 shows a detail of Figure 1, with parts removed for clarity;

    Figures 4 and 5 show respective variations of the Figure 1 dispenser;

    Figure 6 shows a detail of containers, for detergent products, softeners or fresheners that can be used in the dispenser according to the present invention.



    [0011] Number 1 in Figure 1 indicates as a whole a laundry washing machine comprising a parallelepiped-shaped outer body 2; a laundry loading opening 3 formed in a front wall 4 of body 2; and a control panel 5 located on front wall 4, above opening 3.

    [0012] Machine 1 also comprises a dispenser 6 for detergent products or e.g. softeners, fresheners, etc., and which comprises a drawer 7 located in front wall 4, alongside control panel 5.

    [0013] More specifically, as shown in Figures 1-3, drawer 7 comprises an outer handle 8, which is flush with front wall 4 when drawer 7 is in the closed position (not shown); and a slide-in body 9 divided into two sections 10, 11. Section 10 is located at the front, in the opening direction of drawer 7 substantially perpendicular to front wall 4, and is in turn divided into two compartments 10a, 10b, normally for powdered or liquid detergent, and a compartment 10c located inside compartment 10b and normally used for liquid softener.

    [0014] As shown in Figure 2, section 11 is located behind section 10 in the opening direction of drawer 7, and houses one or more containers 12, at least one of which contains a sufficient quantity of detergent for a given number of washes.

    [0015] In the Figure 2 example, section 11 houses one container 12, which may be a refillable container integral with section 11, or a standard cartridge that can be removed from section 11 and changed manually when used up.

    [0016] In the Figure 4 example, section 11 houses two side by side containers 12.

    [0017] In the Figure 5 variation, section 11 is divided into a number of compartments 13 of given sizes, each housing a respective container 12. In this case, too, all or at least some of containers 12 may be integral with respective compartments 13, or defined by known removable cartridges.

    [0018] As shown in Figure 6, the rear end of each removable container 12 has a connector 14 for connecting container 12 to a known hydraulic circuit (not shown) for feeding the detergent to the laundry during the wash cycle.

    [0019] Each container 12 also has a known electronic level identification device 15, which, in use, interfaces with an electronic device (not shown) on machine 1 to automatically meter the product during the wash cycle in known manner.

    [0020] Drawer 7 is mounted inside a compartment 16 in body 2 to slide along two grooves (not shown) extending along respective lateral walls 18 of compartment 16 and engaged in sliding manner by respective longitudinal edges 19 of drawer 7.

    [0021] As shown in Figure 3, dispenser 6 comprises a stop device 20, which, when drawer 7 is opened by the user, retains drawer 7 in a first extracted position (Figure 1), in which section 10 projects from front wall 4, while section 11 remains inside body 2.

    [0022] Stop device 20 comprises two elastic levers 21 (only one shown in Figure 3), each of which is integral with a respective lateral wall 18 of compartment 16, extends parallel to the opening direction of drawer 7, and has a respective triangular tooth 22 projecting towards drawer 7 and movable elastically, in a direction crosswise to the opening direction of drawer 7, between an idle position (not shown), in which tooth 22 presses against relative edge 19, and a work position (Figure 3), in which tooth 22 engages a V-shaped recess 23 formed in a portion of relative edge 19 at the end of section 11 next to section 10.

    [0023] In a variation, stop device 20 may comprise only one tooth 22 and, therefore, only one recess 23.

    [0024] In actual use, when drawer 7 is in the closed position and the user pulls handle 8, drawer 7 slides out until it is stopped in the first extracted position by teeth 22 engaging respective recesses 23. This configuration allows free access by the user to all the compartments 10a, 10b, 10c in section 10 to load detergents or similar manually.

    [0025] Conversely, to operate machine 1 in automatic dispensing mode, and to insert or change or refill one or more of containers 12, the user simply pulls further on handle 8 to exert sufficient force initially on drawer 7 to overcome the resistance of teeth 22 and flex levers 21, so that teeth 22, sliding along respective sloping surfaces of respective recesses 23, slide out of recesses 23 into the idle position, and drawer 7 can be pulled open into a final second extracted position, in which section 11 projects completely from front wall 4 and is fully accessible to the user.

    [0026] The advantages of dispenser 6 in terms of easy, versatile use of machine 1 will be clear from the foregoing description.

    [0027] Machine 1, in fact, can be used in the same way as a conventional manually loaded dispenser machine, as well as in automatic dispensing mode; and section 11 in drawer 7 for housing container/s 12 enables container/s 12 to be changed or refilled as easily as in conventional manual loading mode.

    [0028] Finally, it should be pointed out that the above, relative to dispenser 6, also applies in the event dispenser 6 is used in a drying machine, as opposed to laundry washing machine 1.
