    DESCRIPTION
    [001] The present invention relates to a household appliance containing water, for example a washing machine or a dishwasher, and a method for operating this appliance.
    [002] Nowadays it is known to use household appliances containing water, for example washing machines and dishwashers, in which one or more items (for example clothes or crockery) can be loaded and treated with water and one or more additives (eg wash/rinse products).
    [003] The dosage or the additive is always a complicated issue, as too low an amount of additive can compromise the washing efficiency, while too high an amount of additive has the problem that some additive may settle on the washed items and remain in them even after removing them from the appliance and/or they could be a source of pollution.
    [004] The correct amount of additives is related to the specific treatment cycle (eg wash cycle) and the volume (or quantity, or weight) of items loaded.
    [005] There is, therefore, a need to know the exact amount of additive that has to be supplied to the device in relation to the selected treatment cycle and the quantity of items loaded.
    [006] As mentioned above, a household appliance containing water can be, for example, a washing machine or a dishwasher.
    [007] It should be noted that in the present application, the expression "washing machine" refers to both simple washing machines (ie washing machines that can only wash and rinse clothes) and washing machines and dryers laundry (ie washing machines that also dry clothes).
    [008] Known washing machines generally comprise an outer casing with a washing compartment that contains a rotating perforated drum where the laundry is placed (in this case the items to be washed).
    [009] The drum is rotated by an electric motor that can be connected to a rotating shaft of the drum by a belt pulley system or it can be a so-called "direct drive motor", that is, a motor fixed to the washing compartment and directly connected to the rotating shaft of the drum.
    [010] A loading/unloading door ensures access to the compartment and drum.
    [011] Washing machines typically comprise a detergent supply unit and a water inlet circuit for the introduction of water and additives, in that case washing/rinsing products (i.e. detergent, softener, etc.) , in the compartment. Known washing machines are also provided with water drain devices to drain water from the compartment.
    [012] According to the known technique, a complete washing cycle typically includes different phases during which the laundry to be washed is subjected to appropriate treatments. A wash cycle normally comprises a wetting phase with the addition of washing products, i.e. detergent, and a main wash phase during which, according to the washing program selected by the user, the water contained in the compartment is heated to a predetermined temperature and the drum is rotated to apply a mechanical cleaning action to the laundry. After the main washing phase, the water contained in the drum is drained from the compartment. A successive step of the cycle comprises a rinse phase which typically comprises one or more rinse cycles. In each rinse cycle, clean rinse water is added to the laundry, the drum is rotated and the water is then drained from the compartment to the outside of the washing machine. After the rinsing phase, a final rotation phase allows the extraction of residual water contained in the wet laundry. In the rotation phase, the drum is rotated, typically at a high rotation speed to obtain the extraction of water from the laundry. The water extracted during the rotation phase is drained out through the water drain devices.
    [013] Some washing machines are also provided with a weight measuring device configured to measure the weight of the laundry that is loaded into the washing drum, and with a logic unit configured to determine the required amount of washing product to be used on the basis of the measured weight, and to display via the user interface the amount of detergent to put in the detergent supply unit.
    [014] For example, JP 6233894 discloses a washing machine that is provided with a control panel comprising the operation of key switches as an input means to allow the user to manually select the laundry product, namely the laundry detergent. be used "concentrated", "normal" and "liquid", and set the water surface level. The washing machine is also equipped with a microcomputer configured to: detect the amount of laundry loaded, set the surface water level based on the detected amount of laundry loaded and determine the amount of washing product to be used, based on the selected wash product, the set surface water level and the amount of laundry loaded. The microcomputer is further configured to display the determined amount of laundry product through a viewing window on the control panel.
    [015] However, this washing machine cannot determine the correct amount of laundry product to be used in the wash cycle when the type of washing product selected by the user is not stored in the microcomputer. In addition, detergent producers often modify characteristics of wash products, i.e. the amount of wash product to be used per kilogram of laundry during certain wash programmes. In that case, the washing machine's microcomputer (disclosed in JP 6233894) can determine the amount of detergent based on incorrect data, and consequently presents incorrect information about the amount of washing product to be used.
    [016] US 2010/0186460 A1 discloses a washing machine which operates using a method for adding solid or liquid detergent active ingredients in portions and comprises an electronic program control unit in addition to devices for the introduction and/or determination of information concerning the desired or necessary composition of a treatment program, to determine and/or enter parameters, i.e. the type of washing introduced in the washing machine, the degree of soiling and/or the weight of said laundry. Information concerning active detergent and laundry ingredients is read by information vehicles read automatically via a reading device and the program control unit calculates and issues recommendations for the addition of a particular type of detergent active ingredient and the quantity of said ingredient together with that information, the chosen treatment program and the parameters related to the washing. In detail, the washing machine comprises a reading device that recognizes transponders, i.e. RFID markers. Such a reading device recognizes garments with transponders, i.e. the package of a detergent active ingredient containing information concerning the accompanying detergent active ingredient. Instead of a reading device and in case a washing machine is connected to a data network via a data network interface, the data can also be read at any point in the data network or left from there. back to the washing machine control unit.
    [017] Unfortunately, using the reading device and/or data network interface in the washing machine, as disclosed in US 2010/0186460, causes the complexity and cost of the machine to increase. Furthermore, the washing machine with a reading device disclosed in US 2010/0186460 binds users to the use of detergent packages provided with the transponders.
    [018] The purpose of the present invention is as such to obtain a household appliance containing water, for example a washing machine or a dishwasher that, on the one hand, can inform the user about the right amount of any type of additive to be used in a treatment cycle, this is without any limitation on the type of additive used and on the other hand does not require any additional complex and/or costly devices like data network interfaces or reading devices.
    [019] It is, therefore, the objective of the present invention to solve the aforementioned problems, thus eliminating the disadvantages of the aforementioned prior art.
    [020] The Applicant has found that by using a domestic appliance containing water configured to be programmed by the user to store information relating to the predetermined maximum amounts of additive associated with the maximum carrying capacity of the appliance, for example in accordance with the recommended values provided by the additive producer, it is possible to provide the user, before starting a treatment cycle (for example a wash cycle), with information about the right amount of additive to be used to treat the actual amount of parts loaded in a cycle. selected treatment, without requiring online updates or reading devices or other complex solution.
    [021] The above objective and objects, as well as others that will become clearer later on, are achieved by a household appliance containing water comprising: - a treatment chamber in which one or more items can be loaded and treated with water and one or more additives; - a logic unit to control the electrical and/or electronic components of the apparatus so that the latter performs a treatment cycle to treat the one or more items with water and one or more additives; - a device for charge quantity acquisition to acquire and communicate to the logical unit information related to the quantity of one or more items in the treatment chamber; - a user interface configured to allow a user to define parameters related to the treatment cycle and the one or more additives to be used during the treatment cycle.

    [033] The method comprises the steps of: - storing in the logical unit, during a programming state, information related to the additive defined by the user through the user interface; the information relating to the additive comprising one or more numerical values that are indicative of the predetermined maximum amount of additive associated with the maximum load capacity of the treatment chamber; and - before the water-containing household appliance starts a selected treatment cycle, perform the following phases: - acquire the quantity of the one or more items loaded by the load quantity acquisition device, - determine the quantity of additive to be loaded for that treatment cycle based on the maximum programmed quantity of additive associated with a selected additive, in quantity acquired of the one or more loaded items and in the selected treatment cycle,- provide the user, through the user interface, with information related to the determined quantity of additive to be loaded.
    [034] Preferably, in the domestic appliance containing water in which the inventive method is performed, the charge quantity acquisition device is configured to detect the quantity of the one or more items loaded in the treatment chamber and/or is configured to allow the user to define a parameter related to the quantity of one or more items loaded in the treatment chamber.
    [035] Advantageously, the inventive method comprises the step of presenting through the user interface a numerical value in grams or milliliters, which is an indicator of the determined amount of additive dosed.

    [039] Preferably, in the method according to the invention, the maximum predetermined amount of additive is associated with a numerical value recommended by the producer of the additive.
    [040] Advantageously, the additive in the inventive method comprises a liquid detergent, and/or a concentrated detergent, and/or a gel detergent, and/or a tablet detergent, and/or a powder detergent and/or a fabric softener.

    [043] The following description refers to an advantageous embodiment of the invention in which the water-containing household appliance is a washing machine 1.
    [044] However, it is clear that the invention can also be applied to other household appliances containing water, for example a dishwasher, not illustrated.
    [045] The washing machine 1 according to the invention which is schematically illustrated in the attached figures is advantageously of the front loading type; it is, however, clear that the invention is applicable, substantially without any crucial modification, to a top loading washing machine.
    [046] It is also clear that the invention can be applied, substantially without any modification, to both a "simple" washing machine (ie a machine that can only wash and rinse clothes) and a washing machine. laundry (ie a washing machine that also dries clothes).
    [047] With reference to Figures 1 to 7, the washing machine 1 comprises an outer casing 2 in whose front wall 2a (the front wall 2a was not shown in Figure 1) an access opening 3 is obtained, provided with a door loading/unloading compartment 4 allowing access to a washing compartment 5 contained in the outer casing 2; the washing compartment 5 contains a rotating perforated drum 6 in which the laundry to be washed, marked with the number 7 in Figures 5 and 7, can be loaded and unloaded. In this advantageous embodiment, the drum 6 therefore includes a treatment chamber in which one or more items (pieces of clothing 7 in this advantageous embodiment) can be loaded and treated with water and one or more additives (products washing/rinsing in this advantageous embodiment).
    [048] The washing compartment 5 is connected to the outer casing 2 preferably by means of a flexible bellows, not shown, connected between the open front surface of the washing compartment facing the access opening 3, and the limit of the last.
    [049] In the example illustrated in Figure 1, the washing compartment 5 is elastically supported by the outer casing 2 by means of a suitable resistant support system, comprising, for example, two or more springs 8; preferably, the oscillations of the washing compartment 5 are attenuated by suitable shock-absorbing devices or dampers 9 interposed between the washing compartment 5 and the bottom of the housing 2.
    [050] Clearly the washing compartment 5 can be associated with the casing in any other suitable way.
    [051] Advantageously, the washing machine 1 comprises a water inlet circuit 10 only partially illustrated in Figure 1, adapted to feed water and washing/rinsing products to the washing compartment 5; the water inlet circuit 10 comprises, for example, a removable drawer 10a, adapted to be filled with washing and/or rinsing products, for example liquid or concentrated detergent or gel, or powder detergent, or softener, a tube of inlet 10b, only partially represented in Figure 1, which can be connected to water supply means present on the outside of the washing machine 1 and adapted to supply fresh water to the drawer 10a and to the washing compartment 5 and adapted to supply water and products wash/rinse to wash compartment 5.
    [052] The washing machine 1 also advantageously comprises a drain circuit 11 only partially shown in Figure 1, fluidly connected to the bottom of the washing compartment 5 and adapted to drain the washing/rinsing liquid from the washing compartment 5; in an advantageous embodiment, not illustrated, the drain circuit 11 can also be provided with a recirculation circuit, adapted to drain the washing/rinsing liquid from the bottom of the washing compartment 5, and to readmit such liquid to a region. top of the washing compartment 5 to improve the wetness of the laundry.
    [053] The washing machine 1 also comprises some electrical and/or electronic components, not illustrated, adapted to perform some specific functions: for example, the washing machine may comprise an electric motor to rotate the rotating drum 6, an electric pump adapted to feed the washing/rinsing liquid to the wash compartment 5, an electric pump adapted to drain and/or recirculate the washing/rinsing liquid from the wash compartment 5, an electric heater adapted to heat the washing/rinsing liquid, etc.
    [054] The washing machine 1 advantageously comprises a logical unit (for example an electronic board, a microcontroller, or any other similar electronic control unit/device), schematically indicated in Figure 1, with the block numbered 12, configured to control the electrical and/or electronic components of the washing machine 1 so as to cause the washing machine 1 to carry out a treatment cycle, in this advantageous embodiment a washing cycle, advantageously comprising one or more phases; for example, the wash cycle may comprise a prewash phase, an immersion phase, a main wash phase (comprising, for example, adding water mixed with detergent into the wash compartment 5 and rotating the drum 6 , in order to apply a mechanical action to the laundry), a steam supply phase, a rinse phase, a rotation phase, etc. The washing cycle may comprise one or more of the above-mentioned steps (or also other steps well known in the art) adapted to apply a chemical and/or physical action to the laundry to be washed. A wash cycle phase can be carried out, during a single wash cycle, only once or also twice or more. Clearly, the duration of the total wash cycle depends on the type, number and duration of its phases.
    [055] The washing machine 1 is also equipped with a load quantity acquisition device which, in a preferred embodiment, may comprise a weighing device, schematically represented in Figure 1, with the block numbered 13, which is configured to detect/measure the weight of the laundry 7 loaded into the rotating drum 6. For example, the weighing device 13 may comprise one or more transducers, operatively connected to a logic unit 12; the transducers may comprise, for example, a loading cell or strain gauge and may be associated with the resilient support system 8 supporting the washing compartment 5.
    [056] In another embodiment not illustrated, one or more transducers of the weighing device 13 may be associated with the support of the washing machine 1 (for example, to one or more support feet, not shown, adapted to support the housing 2 of the washing machine 1), in order to detect the overall weight of the washing machine 1 (in the latter case, the weight detected by one or more transducers increases when the laundry is loaded into the rotating drum 6).
    [057] In another embodiment thereof, the weighing device 13 may comprise one or more transducers, not listed, configured to detect a variation in the length of the shock absorbing devices or dampers 9 and to communicate this information to the logic unit 12 configured to associate this variation in length with a variation in the weight of the washing compartment 5 and as such to the weight of the laundry 7 loaded into the rotating drum 6. For example, one or more of the dampers 9 interposed between the washing compartment 5 and the bottom of the housing 2 may comprise a piston 9a movable in a cylindrical housing structure 9b, and a device, not illustrated, adapted to measure the position of the piston 9a within the housing structure 9b; such device may comprise a coil unit wound around the housing 9b of the shock absorber 9 and a sensor element located at the end of the piston 9a located within the cylindrical housing structure 9b. The sensor element can be made of metal, for example iron. The coil unit is connected by a wire to an evaluation unit of the washing machine 1, operatively connected to the logic unit 12 (the evaluation unit can for example be comprised in the logic unit 12). When the piston 9a, and thus the sensor element, moves, for example due to loading the washing machine 1 with laundry 7, the sensor element changes the inductivity of the coil unit. Since the change in inductivity is proportional to the depth of penetration of the piston 9a into the coil unit, the length of travel of the piston 9a can be determined by the evaluation unit. The logic unit 12 can in that case be configured to calculate the weight of the laundry loaded into the rotating drum 6 as a function of the measured path length of the piston 9a.
    [058] However, it is stressed that the use of a particular weighing device 13 is not critical to the invention, and as such substantially any device adapted to measure the weight of laundry 7 loaded into the rotating drum 6 can be used.
    [059] In another advantageous embodiment, the charge quantity acquisition device can be configured to allow a user to define a parameter (eg weight) related to the quantity of the one or more items (clothing 7 in that advantageous embodiment) loaded in the treatment chamber (the drum 6 in that advantageous embodiment). In that case, the charge quantity acquisition device may advantageously comprise an input device, for example a selector, a switch, a button, a region of a touch screen, etc. arranged to allow the user to communicate to the logic unit 12 information relating to the quantity of items loaded, for example the weight of the laundry loaded (which can be estimated by the user or measured for example by a weighing device external to the washing machine) , or the fact that the wash cycle has to be performed for an amount of laundry that is half the maximum allowable load (so-called "half load" cycle or program).
    [060] The washing machine 1 comprises a user interface 14 operatively linked to the logic unit 12 and configured to allow the user to manually define a washing cycle to be carried out, and to select a type of additive (in this case, a washing product , i.e. a detergent, a softener or any other similar washing product) to be used during the wash cycle.
    [061] The user interface 14 may comprise, for example, a touch screen display adapted to present information and receive information input from the user and or may comprise one or more keys, and/or switches and/or buttons and /or displays etc., allowing the user to receive information and enter instructions/commands directed to the logic unit 12.
    [062] Advantageously, the user interface 14 is further configured to allow the user to program during a programming state, "information relating to the additive (in this embodiment, washing product)" indicative of the maximum amount of additive ( in that embodiment, washing product) which is suitable (preferably recommended by the additive producer) for the loading capacity of the drum 6 of the washing machine 1.
    [063] In other words, the user, through the user interface 14, can program washing machine 1 with one or more values indicative of the maximum recommended amount of specific washing products (preferably this recommended maximum amount was determined by the producer of additive) for a maximum weight of laundry that can be loaded into the rotating drum 6 of the washing machine 1.
    [064] User interface 14 can be further configured to present user information; such information may comprise the name of a particular wash cycle, the weight of the laundry loaded, the duration of the wash cycle, the temperature of the wash/rinse liquid, the speed of rotation, etc. More generally, the user interface 14 is designed to present information relating to the wash cycle and/or the status of washing machine 1.
    [065] According to the present invention, the user interface 14 is further configured to provide/suggest the right dose/amount of washing product that the user must fill/load into drawer 10a before washing machine 1 starts to carry out the selected wash cycle to wash a certain amount (weight) of loaded item (clothing). The user interface 14 is configured to present information related to the dose/amount of wash product that the user must manually fill/load into the removable drawer 10a after the wash cycle and wash product have been selected, but before to start the wash cycle.
    [066] In the embodiment illustrated in the attached figures, the user interface 14 advantageously comprises a display device, preferably an LCD or an LED display, designed to present information to the user, and a separate input device, not illustrated, comprising for example a keyboard, and/or a set of keys or buttons and/or one or more touch sensitive information input devices, etc., adapted to set a wash cycle and information relating to the wash product .
    [067] In another embodiment, not illustrated, the user interface 14 may comprise a touch-sensitive display adapted both to present information to the user and to allow the user, by touching some specific zones of that touch-sensitive display, to define a cycle of washing and information on the additive (washing product).
    [068] In another embodiment, not illustrated, the logic unit 12 can be advantageously integrated in the user interface 14.
    [069] It is emphasized that in this application, the expression "program the information related to the additive (washing products, in the illustrated advantageous embodiment)" is intended to mean the following:- select one or more types of additive (products of washing, in the illustrated advantageous embodiment), for example detergents, comprised in a list of additive types (e.g. powder, liquid, gel, tablets, etc.), stored in the memory of the logic unit 12 (if such a list is provided) or manually entered by the user through the user interface 14.- program, for a selected additive, the maximum amount of additive associated with the maximum load capacity of the water-containing appliance 1 (for example, in a washing machine 1 , programming the maximum weight of laundry that can be loaded into the rotating drum 6.
    [070] For example, the user can select/define, through the user interface 14, a washing product corresponding to a "concentrated detergent", a "liquid detergent", a "powder detergent", a "powder detergent", gel", a "tablet detergent", a "softening detergent" or any other detergent suitable for a wash cycle present in a stored additive type list (or the user can manually add a new additive type, optionally to be added to the stored additive type list, if provided, via the user interface 14), and he can set the maximum amount of additive calculated by the additive producer, based on the maximum laundry capacity of drum 6.
    [071] For example, the user can obtain/read information regarding the additive to be programmed, on the packaging of an additive (eg, washing products), which typically contains information regarding the suggested dose of additive and program the maximum amount of additive based on reading the information relating to the additive.
    [072] After the user has programmed the maximum amount of additive, and before washing machine 1 starts a selected wash cycle, logic unit 12 preferably acquires the weight of the loaded laundry 7 (or the user manually enters related information with the weight of the laundry loaded, for example you can define the "half load" cycle) and the type of washing product selected by the user (information that can be provided by the user via interface 14) and calculate the right amount of additive (by example washing product) to be added to apparatus 1 (for example in drawer 10a) based on the maximum amount of additive stored associated with the type of additive selected, the weight of laundry loaded and the selected wash cycle.
    [073] For example, Figures 2, 3 and 4 illustrate a washing machine 1 and the user interface 14 during a programming state in which the user programs the information relating to washing products (additive), i.e., the maximum amount of washing products (additive) associated with the load capacity of drum 6, while figures 5, 6 and 7 illustrate the condition in which the user defines the washing cycle and load of clothes 7 into the rotating drum 6 and preferably at the same time, the user interface 14 presents the calculated dose/amount of washing product (additive) to be used.
    [074] With reference to Figures 2 and 3 showing an example of the programming status, the user selects a washing product to be programmed (a detergent/softener), via the user interface 14 (for example by pressing an icon showing the word "LIQUID" on a touch screen advantageously understood in user interface 14; after selection, user interface 14 presents a settings window providing a message inviting the user to set the recommended value/amount of the selected detergent to be associated at the maximum load capacity of the drum 6. For example, the value of the maximum amount of detergent can be adjusted and displayed via the 14 user interface in grams (as in Figure 3), or milliliters, or number of tablets, depending on the type of washing product that the user has selected. It is evident that in the case of liquid detergent or gel or liquid or gel softener, the maximum amount is preferably regulated/displayed and m milliliters, whereas for powder detergent the maximum amount is preferably set/displayed in grams. For example, the user can adjust a numerical value indicating the amount of washing product by pressing control keys/icons present on the user interface 14 and command the storage of the selected numerical value by pressing one or more confirmation keys/icons.
    [075] In the advantageous example shown in Figure 4, during the programming state of the additive (wash product) information, a user interface programming window displays a selected detergent and a numerical value of the maximum amount of detergent that the user has to define; for example, in Figure 4, the user interface 14 shows that the selected washing product is a liquid detergent and the numerical value indicative of the maximum amount of liquid detergent programmed by the user (for example according to the indication of the detergent producer) it is 80 grams for a load capacity of about 8 kg; after setting the maximum amount of liquid detergent, the user interface 14 invites the user to confirm the set/programmed numerical value.
    [076] After having finished programming the maximum amount of a certain type of washing product, the user can repeat, via user interface 14, the above operations for one or more other types of washing product. For example, in Figure 4, after having completed the programming of the maximum amount associated with a liquid detergent, the user starts to define a washing product corresponding to a concentrated detergent and adjusts the numerical value indicators of the maximum amount of concentrated detergent recommended by a detergent producer in order to fix it at 40 g corresponding to the load capacity of drum 6 of 8 kg; after programming the maximum amount of concentrated detergent, the user interface 14 invites the user to confirm the maximum dose assigned to the concentrated detergent.
    [077] In another embodiment, not illustrated, the logic unit 12 is configured to allow the user to add (for example via user interface 14) to the detergent type list shown for example in Figure 3 (in this case, the list comprises three types of additives which are CONCENTRATE, LIQUID, SOFTENER), other types of additives that can be defined/programmed (eg a POWDER detergent, a GEL detergent, etc.).
    [078] In the example shown in Figures 5, 6 and 7, the user is loading the laundry 7 into the drum 6 and is setting the wash cycle and wash product before starting the wash cycle; preferably during the loading of the laundry 7 (but in another advantageous embodiment this step can also be carried out after loading, i.e. when the loading procedure has already ended, which can be communicated to the logic unit 12, for example) by a suitable switch connected to the open/closed state of the door 4), the user interface settings window 14 advantageously suggests/displays to the user the calculated dose of liquid detergent to be added to drawer 10a. For example, in Figure 6, the user has defined liquid detergent and wash cycle number 1; the logic unit 12 advantageously calculates the right dose of liquid detergent based on the measured weight of the laundry loaded 7, the maximum stored quantity associated with the liquid detergent and the selected wash cycle; the user interface 14 presents the calculated dose of liquid detergent to be suggested to the user.
    [079] In another advantageous embodiment, the information related to the amount of charge is entered by the user for example via the user interface 14; in that case, the logic unit 12 calculates the right dose of liquid detergent based on the information entered in relation to the quantity (for example weight) of the laundry 7 loaded, the maximum stored quantity associated with the additive and the selected washing cycle; and the user interface 14 presents the calculated dose of liquid detergent to be suggested to the user.
    [080] With reference to Figure 8, a preferred embodiment of the inventive method for operating water-containing apparatus (eg a washing machine 1) made in accordance with the principles of the present invention should now be described, advantageously with particular reference to a washing machine 1.
    [081] It is, however, clear that the same method can be applied without any crucial modification to other household appliances containing water, for example a dishwasher.
    [082] In the initial phase, the programming status of information relating to the additive (washing product, in this embodiment) is started (block 100). The programming state can be performed when the water-containing household appliance (washing machine 1, in this embodiment) is in an idle state.
    [083] The user selects a type of additive (wash product), ie a detergent (block 110) (user interface shown in Figure 3).
    [084] According to a preferred embodiment, the user interface 14 can be configured to present various types of additives (detergents) that can be selected by the user. In a different embodiment, the user interface 14 can be configured so that the user can directly input the detergent he wants to program/set.
    [085] After the user has selected (or entered) a type of additive, the user interface 14 advantageously presents the programming window to allow the user to regulate/set the numerical value associated with the maximum amount of the selected additive (product of washing) according to the recommendation/ indications provided by the additive producer (product washing) (block 120) (Figure 3).
    [086] After the user has defined the maximum amount of additive (wash product), preferably the user interface 14 advantageously invites the user to confirm the maximum programmed/set amount of additive (wash product) (block 130 ) (Figure 4).
    [087] In the negative case (NO output of block 130), preferably the method executes the previous phase (block 120), while in the positive case (YES output of block 130), preferably the logic unit 12 stores in a memory the program/fixed quantity associated with the type of additive selected (washing product) (block 140).
    [088] The logic unit 12 advantageously checks whether another type of additive (washing product) has been selected/defined by the user (block 150), and if so (YES output from block 150), the operating phases revealed in the blocks 110-140 are advantageously repeated for the other type of additive (washing product) (Figure 4), while in the negative case (NOT output of block 150), the programming status of information relating to the additive (washing product) ) is terminated advantageously.
    [089] After the definition of the additive information (eg washing product) has been completed, the user can use the household appliance containing water (eg a washing machine 1) to treat (eg wash) the one or more loaded items (clothes in the embodiment of a washing machine, but it can be dishes if it is a dishwasher) getting, after setting the wash cycle and before the household appliance containing water (for example washing machine 1) start the washing cycle, preferably during the loading of items (eg laundry 7) which must be filled/loaded (in the illustrated embodiment, in drawer 10a) for the actual amount of items loaded (per example the actual weight of the laundry loaded 7).
    [090] With reference to Figures 6 and 7, the user selects a treatment cycle (eg a wash cycle called "PROGRAM 1" and the type of additive (eg detergent called "LIQUID") to be used, and loads the item(s) (eg laundry 7) into the treatment chamber (eg rotating drum 6) (block 160). The logic unit 12 determines preferably during the loading of the items (but it is possible that this step is only carried out at the end of the loading phase, the end of which can be communicated to the logic unit 12 for example by a suitable switch connected to the open/closed state of the door 4), the weight of the items (for example laundry 7) loaded in the treatment chamber (by example drum 6) based on the data provided by the load quantity acquisition device (eg weighing device 13) (block 170) and calculates the dose/amount of additive (eg washing product) to be recommended to the user with base on quantity m Maximum stored additive (eg washing product) associated with selected additive, the selected treatment cycle (eg washing cycle called "PROGRAM 1" in Figure 6) and the purchased quantity of loaded item or items (eg determined weight or introduced in clothes) (block 180).
    [091] In another advantageous embodiment, information related to the amount of charge can be entered by the user for example via the user interface 14; in that case, the logic unit 12 calculates the right dose of additive (eg liquid detergent) based on the information entered in relation to the quantity (eg weight) of the item(s) (eg laundry 7) loaded, the maximum quantity stored associated with the selected additive and the selected treatment cycle (eg wash cycle).
    [092] The logic unit 12 controls the user interface 14 to display the calculated dose of additive (wash product) (block 190) and preferably checks the amount of load (eg weight of laundry loaded into drum 6 by user) is changing (block 200). Preferably, if the amount of load is changing (SIM output from block 200), the logic unit 12 performs operational phases revealed in blocks 170-200. Preferably, if the amount of charge is not changing (NOT output from block 200), the user interface 14 keeps displaying the last calculated amount of additive to be charged.
    [093] In a preferred embodiment, the presentation by user interface 14 of the amount of additive to be filled/loaded can end when the appliance door 4 is closed, after loading the items and/or immediately before the appliance containing water starts running the treatment cycle.
    [094] In an advantageous embodiment, the presentation by the user interface 14 of the amount of additive to be filled/loaded can be performed only after the loading of the item(s) is finished, information that can be communicated to the logical unit 12 for example by a suitable switch connected to the open/closed state of door 4 of the water-containing appliance, and/or by a control device (eg a switch or an icon selectable by means of a touch screen, etc.) which can be operated by a user.
    [095] It is clear that the step of storing, during a programming state, information relating to the additive comprising one or more numerical values that are indicative of the predetermined maximum amount of additive associated with the maximum loading capacity of said treatment chamber can be performed , does not have to be performed each time the water-containing apparatus has to be used, since the logic unit 12, once the information relating to the additive has been stored, advantageously stores the information relating to the additive stored so that it can be used to determine the amount of a selected additive to be loaded by any other treatment cycle.
    [096] The water-containing appliance and the method of the present invention have the advantage of being able to inform the user about the right dose/amount of any type of additive before the water-containing home appliance starts a selected treatment cycle, without any limitation on the type of additive used, without requiring any additional complex and/or expensive additional devices such as data network interfaces or reading devices.
    [097] Clearly, changes can be made to the operating method and washing machine as described and illustrated herein, without, however, departing from the scope of the present invention.
