Definitions

  • the present invention relates to a control method of a washing machine and a washing machine, in particular a laundry washing machine or a domestic dish-washing machine, according to the preamble of the annexed claims 1 and 7.
  • domestic laundry-washing machines are equipped with dispensing devices of the washing agents, such as detergents, whiteners, softeners, etc.
  • Such dispensing devices are usually made up of a drawer-like container that is able to be charged with the washing agents, and to be successively passed over by a flow of conveying water.
  • the drawer is usually divided in a series of compartments, each of which is charged with a dosage of detergents or additive to be utilised during the various phases of the washing program; each of such compartments is obviously placed in communication, whilst in the working position, with suitable entrance and water drainage pipes.
  • the user selects a washing program and provides for introducing to the various compartments of the dispenser the recommended quantity of said washing agent; at an appropriate moment, upon a command of the control system (of the electro-mechanical or electronic type) of the machine, the water to be introduced to the washing chamber of the machine is made to pass through each of the various compartments, so as to carry the relative washing agents in the chamber; i.e. based on the selected program, and according to the washing phases reached, the control system provides for withdrawing at appropriate times the various washing agents from the relative compartments.
  • the control system of the electro-mechanical or electronic type
  • washing programs of laundry washing machines can provide for different phases, during which washing agents are introduced to the tub; for instance a washing program can, from among other phases, provide for:
  • Modern laundry washing machines therefore have numerous washing programmes incorporated that can be selected, comprising one or more of the aforementioned phases.
  • the great number of such programs may at times cause the user to make mistakes; for example the case wherein the user introduces, in the various compartments of the dispenser, detergents for the pre-wash, detergents for the wash itself and a softener, and then goes on to erroneously select a program that does not provide for a pre-wash and/or after-wash with softener; also imagine the case wherein the user of a laundry washing machine, or of a dish-washer, starts a program without having introduced to the dispenser device the necessary washing agents: the consequences of such errors are in both cases easily imaginable.
  • washing machine comprising systems for the automatic dosage and addition of the detergent, during a washing program. See for instance US 3,645,669, US 3,223,108 or FR-A-2.455.648.
  • the present invention is based on the acknowledgement of the aforementioned facts and its purpose is that of indicating a washing machine that, with simple and economic means, both being of improved functioning and reliability; further purpose of the present invention is that of indicating a washing machine in which possible operational errors of the user, in relation to the use of washing agents, can be reduced and/or corrected.
  • the present invention has as its subject a washing machine and a control method having the characterizing feature of the annexed claims.
  • the washing machine according to the present invention has a microcontroller type command unit, that works with fuzzy logic, and has an adequate knowledge base, obtained through the experience of technicians and by way of experimental research, and coded in the permanent memory associated to the microcontroller of the control unit; the control unit then has the use of, by way of appropriate measuring means, information relative to physical characteristics of the washing liquid.
  • the machine according to the invention is equipped with an appropriate measuring device of the resistivity of the washing water: in figure 1 one of the possible embodiments of such device is illustrated.
  • Said device for measuring the resistivity of the washing water within a laundry washing machine has two electrodes, indicated in figure 1 with the letters A and B.
  • the electrode A is constituted by an electrically conductive element, arranged in direct contact with the washing liquid, that in the case of figure 1 coincides with the same metallic body V of the machine (tub-basket complex), but could also be isolated from the same by way of an appropriate rubber seal.
  • the electrode B is constituted by an electrically conductive element arranged in direct contact with the washing liquid and isolated with regards electrode A.
  • Such flow of current goes on to supply the transient charge of the capacitor C and stops when such transient has finished, i.e. when a voltage being equal to the value of E is present at the ends of the capacitor C.
  • the duration of the charge transient depends upon the value of the capacitor C and on the value of resistivity of the means (washing water) through which the charge current flows.
  • the measuring of the charge time is carried out by a common commercial microcontroller MP (architectured to 4 or 8 bits) able to measure the time with a good resolution (for instance with a resolution of 1 microsecond).
  • a digital input of the microcontroller MP is connected to the ends of the capacitor C, while its digital output, named OUT, is used for piloting a transistor Q, used as a switch, the collector of which is in turn connected to the ends of the capacitor C.
  • the measure of the charge time of the capacitor C is carried out by the following operations of the microcontroller MP:
  • the microcontroller MP is conveniently programmed according to the fuzzy logic technique, with an adequate knowledge base, coded in the permanent memory (ROM) of the microcontroller, for carrying out the calculation of the resistivity of the liquid in following the measure of the charge time of said capacitor.
  • the laundry washing machine according to the invention has adequate means for detecting the effective introduction of washing agents to the water: in fact the value of the ionic concentration in the water, which gives an indication as to the presence of a washing agent, can be estimated, by way of the memorised knowledge base and the fuzzy logic technique, through the resistivity measure of the liquid after the introduction of said agent.
  • figure 2 represents in a graphical form the result of experimental research that illustrates the relation between the concentration of the detergents and the resistivity, detected with the device of figure 1, expressed in grams per litre, in the presence of a temperature of 20°C (and for a water hardness value of 30°F).
  • the machine according to the invention is in the case described equipped with a dispensing device of washing agents; purely as an explanatory purpose in figure 3 only the drawer of such dispenser is schematically illustrated, indicated as a whole with 10 and divided in three distinct compartments, more precisely:
  • the drawer 10 is contained in an appropriate hopper container, for simplicity not represented in the figure, that has a pipe in its lower section, (F, in figure 4) in communication with the interior of the washing tub of the laundry washing machine (V, in figure 1); the hopper container then has in its superior section means (W, in figure 4) apt at selectively advancing the water from the mains to the single compartments 11, 12 and 13; such water therefore provides for withdrawing the various washing agents from said compartments and for transporting them to the washing tub, by way of the said lower pipe; the control of the means for selectively advancing the water to the various compartments is carried out by the control device of the machine.
  • a pipe in its lower section, (F, in figure 4) in communication with the interior of the washing tub of the laundry washing machine (V, in figure 1); the hopper container then has in its superior section means (W, in figure 4) apt at selectively advancing the water from the mains to the single compartments 11, 12 and 13; such water therefore provides for withdrawing the various washing agents from said compartments
  • control device of the machine and the relative commands are of the simplified type, i.e. realised so as that the presence of a particular phase of a "standard" washing program, characterised by the introduction of a washing agent, be considered optional or, if preferred, normally not present; in the particular case the optional phase is that of the pre-wash.
  • the user loads the washing machine with laundry, introduces the detergents for the washing in the compartment 12 and the additive in the compartment 13, and starts the machine selecting the said "standard" program.
  • the control device of the machine at this point can command the dispenser so as that the water to be charged passes through the compartment 12, for removing the detergents for the washing phase, and the washing program continues in the known manner.
  • the control device of the machine therefore commands the dispenser so as that the water charged from the mains is made to pass the compartment 11 for an amount of time that allows the removal of the detergents for the pre-wash phase, and supervises in a known way the execution of such pre-wash phase; the program then continues, still in a known way, with its other phases, such as the actual wash, the rinses, the softening phase, spinning, etc.
  • the washing program would be executed without the detergents, with a useless waste of time and energy, and with totally unsatisfactory results.
  • the machine according to the invention is able to understand the users mistake, and eventually signal such mistake by way of appropriate means.
  • the sensor of figure 1 checks the absence of detergents; the control device of the machine, by way of its memorised rules is able to act signalling the user.
  • an audio signal could be provided, that signals the user, and a luminous light that signals the absence of detergents; with simple and appropriate programming of the microcontroller, the control device of the machine is also able to act upon the carrying out of the washing program, for instance to interrupt the program until the user carries out a determined operation for instance, the user can open the drawer of the dispenser, insert the necessary detergents and press an appropriate confirmation button, that commands the conveying of the detergents that have just been inserted to the tub, and then continues the program.
  • the pressing of the confirmation button could command the drainage of the water already contained in the tub, so as to repeat the program, or a single phase of which, with the correct addition of the various washing agent or agents.
  • control system of the washing machine provides at appropriate moments for measuring the ionic concentration of the washing liquid, once the resistivity value has been detected, by way of the device of figure 1, and carries out the necessary eventual comparisons; as mentioned such measures can for example take place during the initial phase of the first loading of the water (so as to verify whether a pre-wash is necessary) and at the beginning of every single phase that requires the introduction of washing agents, for detecting the effective presence of such.
  • Figure 4 illustrates an explanatory example of a possible embodiment of the control system of a washing machine, in particular a laundry washing machine, realised according to the present invention.
  • W indicates a supply pipe, apt at selectively advancing water coming from the mains to the various compartments (11-13) of the detergents dispenser 10; with F the said pipe which connects the distributor 10 to the washing tub V of the machine; R indicates the group of the components E,A,B,C and Q of the water resistivity measuring device, described with reference to figure 1; MP indicates said microcontroller, while ROM indicates the permanent memory associated to the microprocessor MP; the ROM memory contains criterion for measuring the resistivity of the washing water and for deducing its ionic concentration.
  • T indicates a programming device of the washing machine, for example of the electromechanical type, connected to the microcontroller MP (the presence of an electromechanical timer is obviously not necessary in the case of machines equipped with an electronic programmer);
  • S indicates the said signalling device, for example an indicator lamp, whilst U indicates a command device, such as a confirmation button.
  • FIG 5 a possible logic flow diagram of the microprocessor MP of figure 4 is represented during the aforementioned "standard" phase of the washing program.
  • block 21 indicates the pre-wash phase, or better the admission of water coming from W in the compartment 11 of the dispenser 10: the water passes through the compartment 11 and reaches, through pipe F, the tub V of the machine;
  • block 22 indicates the liquid resistivity measuring phase and that of deducing the presence of detergents, by way of R and MP (as described with reference to figure 1);
  • block 23 is a control block, for deciding whether to execute the pre-wash phase: if the microcontroller MP does not detect the presence of detergents in the washing liquid that has reached the tub V (No output), the control passes to block 24, that indicates the execution of the actual washing phase; if on the other hand MP deduces the presence of detergents (YES output), control passes to block 25, that indicates execution of the pre-wash phase.
  • control therefore passes to block 26, that indicates a new resistivity measuring phase of the washing liquid, for deducing the eventual presence of detergents;
  • block 27 indicates a control block, for deciding whether to continue with the selected washing program; if the presence of detergents is deduced (YES output), control passes to block 28, for the continuation of the "standard” program; vice-versa, if no presence of detergents id detected (NO output), control passes to block 29, that indicates the activation of signalling means S and the interruption of the washing program;
  • block 30 is a control block, for controlling whether the user has pressed the confirmation button U: the pressing of such button is an indication of the fact that the user has received the signal (and has taken the necessary measures, such as introducing the missing detergents); when the button U is pressed (YES output), control passes to block 31, that the eliminates signalling condition and passes the control to block 26. 31 indicates the end of the "standard” wash program.
  • the measuring of the ionic concentration of the washing liquid can be carried out with a device similar to that of figure 1, in a moment established by the control system of the dish-washer; even in this case, in conditions of an absence of detergents, the control device of the machine can provide for warning the user and/or interrupting the program and/or draining the water already present in the tub, thus allowing the addition of detergents.
  • the implementation of the invention results in being very cost effective, due to the fact that its constituting elements are already normally part of almost all dish-washing machines; in fact the cost of the microcontroller (when not provided with the dish-washing machine) costs approximately one dollar, and, in the same way, the cost of the components of the water resistivity measuring device are practically considered to be insignificant with regards the benefits, in terms of usefulness and efficiency, offered by the control system of the machine subject of the present invention.
  • the measure of the ionic concentration of the water could be improved, or integrated with other information, such as the water hardness and its temperature, the quantity of water charged, the type of laundry to be washed, the type of soil associated to the fabric, etc.
  • an excellent method for enabling the coding in a compact form of the substantial mass of information that the control unit has to treat is that offered by the technology based on fuzzy logic; the knowledge base of the method according to the invention is coded, in the permanent memory of the microcontroller under the form of "rules" (IF...THEN rules) by way of the fuzzy logic technique.
