SUMMARY pznE iNVENTIbN
f003.1 It is a main advantage of this invention to provide for a washing machine that has tanks for various laundry products capable of containing products for several wash cycles.
[004] It is another advantage of this invention to have a system for cont-zSlling the sequence, quantities and types of products required as per user selected options.
[005} In order to do so, the invention comprises a plurality of tanks with each one containing one type of laundry product. Pumping means pump the required amount of laundry product into the tub at predetemiined times during the wash cycle.
[006] The foregoing and other objects, features, and advantages of this invention will become more readily apparent from the following detailed description of a preferred embodiment with reference to the accompanying drawings, wherein the preferred emboqiment of the invention is shown and described, by way of examples. As will be realized, the invention is capaple of other and different embodiments, and its several details are capable of modifir.ations in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

(0016] A laundry washing machine with automatic dispensers (10) is comprised of a plurality of product tanks (12', 12", 12'") with each one containing one type of laurtdry produd_ Pumping nroeans (14', 14", 14"') pump the required amount of laundry product into a tub (16) at predetermined times during ihe wash cycle.
(0017] Laundry produtxs pumpirtg means (14', 14", 14"') are simple in design and are of the type known in the art. For excample pumping means (14', 14", 14'") used in the automotive industry for spraying windshield cleaner could be readily used.
15[00181 Besides the standard buttons found on typical clothes washing machines such as water level button (1), water temperature button (2), type of washing button (5) there is a new type of button located on a washing machine control panel (17) known as product dispensing button (18), with related monitoring lights (4), all controlled by an electronic PCB controller (not shown) which controls the type and amount of the various laundry products that need to be dispended in function of the wash load. Of course, in the case of a wasing mdchine having electronic controls instead of buttons, this function would be Integrated as part of the available functions provided by the control panel. The user inputs the type of loads (smalt, medium, large) on the water level button (1) and a given amount of water fills the tub (16), this part is known in the 5 art, what is new in the interrelation between the amount of water selected and the amount of laudry product dispensed. Given that the pumping means (14', 14". 14"') have a set dispensing volume per second, by simply allowing the given one of the pluraiity of pumping means (14', 14", 14"') to run a given amount of seconds wiM reliably dispense a given amount of laudry product. It is understood that the iaundry detergent needs to be in liquid form as opposed to granular form. What is also relatively new is that at the same time that the user selects its load, the type of washing is also selected, that is detergent;
datergent/bleach; detergent/softener; detergentlbieachlsoftener.
15[0019] Products tanks (12', 12", 12"") are advantageously positioned in the empty eomers (20', 20", 20'") of Conventioani washing machines (22).
Those comers (20, 20'. 20", 20"') are usually empty since the tub (15) is round. For front loading washing machines (22'), comers (20', 20", 20"') can also bu used except that the tanks (12', 12", 12"') would be laid horizontally instead of vetacaiiy but would stiq be capable of holding the same amount of laundry products. The tanks (12', 12", 12"') can be grouped together or can be spaced apart, one per each of the comers (20', 20", 2D'"). A funnel conduit (21', 21", 21") leads a iaundry product that is being poured into any given tank tank (12', 12",12 25[0020) Products tank (20', 20", 20"') are mare of compounds designed to withstand the long term chemical effect that laundry products can have and so are the hoses (24', 24", 24'") and intemal pump means components (not shown) that come in contact with the laundry products.
