Description
- The present invention relates to a laundry washing machine dispenser for detergent products or similar.
- 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.
- 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.
WO-A-8806199 - 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.
- It is an object of the present invention to provide a laundry washing machine dispenser for detergent products or similar, 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.
- According to the present invention, there is provided a laundry washing machine dispenser for detergent products or similar, as claimed in
Claim 1 and, preferably, in any one of the Claims depending directly or indirectly onClaim 1. - 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 theFigure 1 dispenser in a different operating configuration; -
Figure 3 shows a detail ofFigure 1 , with parts removed for clarity; -
Figures 4 and 5 show respective variations of theFigure 1 dispenser; -
Figure 6 shows a detail of containers, for detergent products or similar, that can be used in the dispenser according to the present invention. -
Number 1 inFigure 1 indicates as a whole a laundry washing machine comprising a parallelepiped-shapedouter body 2; alaundry loading opening 3 formed in afront wall 4 ofbody 2; and acontrol panel 5 located onfront wall 4, above opening 3. -
Machine 1 also comprises adispenser 6 for detergent products or similar, e.g. softener, freshener, etc., and which comprises adrawer 7 located infront wall 4, alongsidecontrol panel 5. - More specifically, as shown in
Figures 1-3 ,drawer 7 comprises anouter handle 8, which is flush withfront wall 4 whendrawer 7 is in the closed position (not shown); and a slide-inbody 9 divided into twosections Section 10 is located at the front, in the opening direction ofdrawer 7 substantially perpendicular tofront wall 4, and is in turn divided into twocompartments compartment 10c located insidecompartment 10b and normally used for liquid softener. - As shown in
Figure 2 ,section 11 is located behindsection 10 in the opening direction ofdrawer 7, and houses one ormore containers 12, each containing a sufficient quantity of detergent or similar for a given number of washes. - In the
Figure 2 example,section 11 houses onecontainer 12, which may be a refillable container integral withsection 11, or a standard cartridge that can be removed fromsection 11 and changed manually when used up. - In the
Figure 4 example,section 11 houses two side byside containers 12. - In the
Figure 5 variation,section 11 is divided into a number ofcompartments 13 of given sizes, each housing arespective container 12. In this case, too, all or at least some ofcontainers 12 may be integral withrespective compartments 13, or defined by known removable cartridges. - As shown in
Figure 6 , the rear end of eachremovable container 12 has aconnector 14 for connectingcontainer 12 to a known hydraulic circuit (not shown) for feeding the detergent to the laundry during the wash cycle. - Each
container 12 also has a known electroniclevel identification device 15, which, in use, interfaces with an electronic device (not shown) onmachine 1 to automatically meter the product during the wash cycle in known manner. -
Drawer 7 is mounted inside acompartment 16 inbody 2 to slide along two grooves (not shown) extending along respectivelateral walls 18 ofcompartment 16 and engaged in sliding manner by respectivelongitudinal edges 19 ofdrawer 7. - As shown in
Figure 3 ,dispenser 6 comprises astop device 20, which, whendrawer 7 is opened by the user, retainsdrawer 7 in a first extracted position (Figure 1 ), in whichsection 10 projects fromfront wall 4, whilesection 11 remains insidebody 2. -
Stop device 20 comprises two elastic levers 21 (only one shown inFigure 3 ), each of which is integral with a respectivelateral wall 18 ofcompartment 16, extends parallel to the opening direction ofdrawer 7, and has a respectivetriangular tooth 22 projecting towardsdrawer 7 and movable elastically, in a direction crosswise to the opening direction ofdrawer 7, between an idle position (not shown), in whichtooth 22 presses againstrelative edge 19, and a work position (Figure 3 ), in whichtooth 22 engages a V-shaped recess 23 formed in a portion ofrelative edge 19 at the end ofsection 11 next tosection 10. - In a variation,
stop device 20 may comprise only onetooth 22 and, therefore, only one recess 23. - In actual use, when
drawer 7 is in the closed position and theuser pulls handle 8,drawer 7 slides out until it is stopped in the first extracted position byteeth 22 engagingrespective recesses 23. This configuration allows free access by the user to all thecompartments section 10 to load detergents or similar manually. - Conversely, to operate
machine 1 in automatic dispensing mode, and to insert or change or refill one or more ofcontainers 12, the user simply pulls further onhandle 8 to exert sufficient force initially ondrawer 7 to overcome the resistance ofteeth 22 and flex levers 21, so thatteeth 22, sliding along respective sloping surfaces ofrespective recesses 23, slide out ofrecesses 23 into the idle position, anddrawer 7 can be pulled open into a final second extracted position, in whichsection 11 projects completely fromfront wall 4 and is fully accessible to the user. - The advantages of
dispenser 6 in terms of easy, versatile use ofmachine 1 will be clear from the foregoing description. -
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; andsection 11 indrawer 7 for housing container/s 12 enables container/s 12 to be changed or refilled as easily as in conventional manual loading mode. - Finally, it should be pointed out that the above, relative to
dispenser 6, also applies in theevent dispenser 6 is used in a drying machine, as opposed tolaundry washing machine 1.
