Definitions

  • the present invention refers to a washing machine.
  • the German type of approach also known as the "input system” provides for a user-appliance interface, i.e. a control panel, equipped with lots of buttons, lights and dials, provided for selecting the multitude of possible parameters and functions.
  • a control panel equipped with lots of buttons, lights and dials, provided for selecting the multitude of possible parameters and functions.
  • Such control panel is obviously made more complicated by the increase of the functions, as a consequence of the utilisation of the electronic control techniques.
  • the user has to input a great number of parameters and select the various functions of interest, and the electronic control system of the machine, acting on the inputs received and elaborating them, provides for carrying out a complete washing cycle.
  • the electronically controlled washing machine provides, in normal use, a single command means, which corresponds to the starting button of the washing cycle; the user is not therefore called upon to insert any input being particular to the electronic control system, thus in such situation it can be stated that the washing machine completely "dominates" the user.
  • the machines are also equipped with a complicated keyboard, for the completely manual programming of the multitude of operative parameters.
  • the manual programming option is selected, the user has to face the problems of complexity as expressed above, with reference to the programming approach of the "input system".
  • the user is called upon to supply numerous types of information (fabric type, quantity of fabric, washing temperature, spin speed, water hardness, etc.) thatcalls for a certain mental care and reasoning, and without which the household appliance, notwithstanding its capacity, is not able to function correctly; in view of its complexity, it may occur that the user forgets to supply some important information.
  • information fabric type, quantity of fabric, washing temperature, spin speed, water hardness, etc.
  • French patent FR-2 429 579 A discloses a dishwashing machine comprising an electronic control system and manual command means in the form of a keyboard associated to a display panel. Said washing machine is able to choose, in function of the information on the dishes type obtained by way of said keyboard , a predetermined treating cycle from among a plurality of different possible treating cycles stored in the memory of the control system.
  • the control system there disclosed operates through an electronic programmer that has necessity only of the information, inputted by the user by way of said keyboard, relative to the type of dishes loaded, the other parameters that determine the treating cycle being obtained in an automatic way by the programmer, through data coded in said memory.
  • the washing machine here disclosed suffers some drawbacks. In fact, there is no possibility of correlating the treating cycle to be choosen to the working conditions in which the choice is made, since the treating cycle is univocally determined by the user input. Another drawback is that there is no control on the correctness of the information inputted by the user. From DE-4 202 656 A a washing machine is known for which the user selects a program, e.g. "delicate items" to be performed by an electronic control system. The program which is selected by a program selector is associated to laundry-related parameters which are sensed after the beginning or during the washing cycle. The sensed parameter values are used to automatically modify or adapt the selected program.
  • the purpose of the present invention is that of overcoming the abovementioned drawbacks and of realising a control panel of a washing machine with a sophisticated electronic control, with the aim of rendering the dialogue between the user and the washing machine extremely simple and, at the same time, however being able to fully satisfy the mutual necessity, from the user to the machine and vice versa, of information being actually necessary.
  • the aims that the present invention intends to reach are obtained substantially by way of the electronic control system of the household appliance, which is equipped to carry out the three following related and complimentary actions.
  • the performance desired can be understood as the washing of the laundry without wearing the fibres, with a saving of water and electricity and having respect for the environment, to be obtained in relation to functional conditions of the machine such as the value of the power supply, the hardness level of the water, the quantity of detergents introduced by the user, the quantity and type of laundry, the quantity and type of dirt, the load unbalance entity of the laundry in the basket, etc.
  • washing machines such as a laundry washing machine and a dishwashing machine, on which the present invention finds a use being particularly advantageous.
  • Such laundry washing machine and dishwashing machine are schematically represented in figures 1 and 2.
  • the laundry washing machine indicated as a whole with 1 has an extremely simplified control panel 2.
  • a smooth turning dial, indicated with 3, a LED display, indicated with 4 and a program starting button, indicated with 5 are in fact sufficient: as shall be explained in the following of the present description, such means are sufficient for exchanging with the user information being strictly necessary for obtaining the desired results, i.e. a washing program predetermined or complete, that the household appliance is able to express, in virtue of its sensor means and the control technique based on fuzzy logic.
  • buttons are further supplied, respectively indicated with 6 and 7, and respectively carrying the symbols "+" and "-".
  • control panel 2 On the control panel 2 a traditional general switch of the machine is finally indicated with 8, for enabling the electrical power supply, and with 9 a drawer of a washing agents dispenser; the panel 2 can also eventually have indicating lamps for signalling one or more functional conditions of the machine.
  • the dishwashing machine of figure 2 in practice has the same control elements as those represented in figure 1 on the laundry washing machine, and for this reason the elements have been distinguished with the same reference numbers, with the addition of the letter "A"; with 10 a handle is indicated for realising the opening of the frontal loading door of the dishwashing machine; naturally in the case of the dishwasher the drawer of the washing agents dispenser is not present, because such device, as is known, is housed on the inner door of the machine.
  • the only substantial difference between the control panels 2 and 2A of the dishwashing machine and the laundry washing machine is the printing on the controls 3 and 3A.
  • the dial 3 will be provided for the selection from among six options, corresponding to the following types of laundry to be washed: woollens, delicate fabrics, synthetics, coloured fabrics, very strong fabrics, or very dirty; such options can for instance be represented by way of graphic symbols, the likes of which recall the type of laundry.
  • the dial 3A will be for instance provided with the selection from among five options, corresponding to the following types of dishes to be washed: crystal, pots and pans, dishes with a normal level of soil, dishes with a low level of soil, wherein with crystal particularly delicate items are intended, such as for instance crystal glasses, whereas with pots and pans, items that can withstand vigorous treatment are intended, such for instance pans with a particularly resistant soil.
  • the electronic control system of the two washing machines 1 and 1A is of the type based on the use of a microcontroller, to which appropriate means are associated for realising the various actions in relation to the type of washing required; such control system provides for, in other words, a programmer, or timer, of the electronic type with which appropriate memory means are associated, within which the rules for realising the washing programs is stored in an appropriate manner.
  • control system sensor means are also associated, which allow for the control system in practice to obtain all the necessary quantitative information for the carrying out of the normal washing cycle.
  • such sensor means comprise:
  • such sensor means comprise:
  • the laundry washing machine 1 and the dishwashing machine 1A will reply in the following way.
  • the electronic control system Upon turning on the washing machine 1 or 1A, by way of the general switch 8 or 8A by the user, the electronic control system will make appear on a display 4 or 4A a simplified graphic information, expressing the level of water hardness present in the mains supply with which the washing machine is connected.
  • Such value of the water hardness shown on the display 4 or 4A is a "historic" value, i.e. obtained by way of measures carried out by the abovementioned hardness sensor, day after day, wash after wash, and stored, with a technique in itself known, in an appropriate way, in permanent memory means associated to the microcontroller which manages the control system of the machine.
  • three water hardness levels are established, i.e. low, medium or high, that are represented for instance on the display 4 or 4A respectively by way of one, two or three horizontal bars.
  • Such information relative to the water hardness is used by the user for carrying out, in the best way possible, the dosage of the detergents, in accordance with the amount specified by the producer of the washing agent; it is in fact known that such companies usually indicate, on the package of their products, the best quantity of detergent to use in accordance with the level of hardness of the water coming from the mains supply.
  • the dishwashing machine 1B on the display 4A seven levels of water hardness are indicated; such information being more accurate, represented for instance by a number of horizontal bars corresponding to the hardness level memorised, is useful to the user for appropriately adjusting the brightener dosing device; it is in fact known that, similarly as that which takes place for the detergents in the case of laundry washing machines, the recommended dosage of brightener to be associated to each wash of dishes varies according to the hardness of the water.
  • the user can close the loading door of the machine and appropriately position the control dial 3 or 3A, for indicating to the control system the most delicate item to be washed, in the case of the laundry washing machine, or the type of dishes or the dirt level, in the case of the dishwashing machine 1A. At this point the user can start the washing cycle, pressing the appropriate button 5 or 5A.
  • control system Upon such action, the control system provides for making appear on the display 4 or 4A the temperature value that the control system itself has chosen in an automatic manner, in function of the "qualitative" information that the user inputted by way of the dial 3 or 3A, in virtue of the knowledge base encoded in the memory means.
  • the user only if desired, can modify such temperature value, but only within determined "safety" limits which the machine allows; i.e. be it in the case of the laundry washing machine 1 or in the case of the dishwashing machine 1A.
  • the temperature can be modified by the user by way of the appropriate increase buttons 6 or 6A (+) or the decrease buttons 7 or 7A (-).
  • control system of the laundry washing machine 1 imposes, so as to avoid damaging the fabric, a maximum limit to the temperature value, above which the user cannot go; such maximum limit is strictly correlated to the position selected by way of the dial 3, through which the user supplies the information relative to the most delicate item loaded in the machine.
  • a maximum temperature value and a minimum temperature value are associated and the user can therefore propose the eventual variations, by way of buttons 6A and 7A, only within such range; in the case of the dishwashing machine the maximum limit has the purpose to avoid damaging the dishes, while the lower limit has the purpose of guaranteeing the washing performance; even in such case the imposed limits are correlated to the position selected by way of the dial 3A.
  • a time estimate of the activated washing cyde appears, calculated by the microcontroller of the control system by way of its internal clock; such time indication, that can for instance be expressed in hours and minutes, is updated by the control system with the passing of time, so as give a backward count.
  • the washing program is therefore managed by the control system, that will appropriately command the various agent devices of the machine, making use of the information obtained by way of its various sensors, its programmed functional rules and the information coming from the user.
  • the control system of the machine according to the invention is programmed according to the fuzzy logic technique, in virtue of the capacity of such technique to manage information being of the "qualitative" type.
  • dial 3 or 3A is an instrument that allows the user to condition in an important manner the washing strategy chosen by the control system from among the various strategies available, in consideration of the data detected by the sensors; in other words, therefore, the user does in fact have the possibility of dominating the machine, despite the high level of technology, with a very simple operation, such as rotating the dial.
  • the information associated to the dial 3 or 3A is of the qualitative type, i.e. being substantially relative to a single characteristic of the article that the machine has to treat, and deriving from the day to day experience of the user.
  • control system of the machine according to the invention can be when needed programmed for controlling, within certain limits, the correctness of the selection carried out by the user of the dial 3; in other words, therefore, the control system is able to detect eventual discrepancies between the type of laundry actually introduced in the machine 1 and the type of laundry selected by way of the dial 3.
  • the control system will be able to detect the discrepancy between the inputted information and the reality, by way of the said sensor of the type of laundry (for such aims note , as previously mentioned, the Italian patent application T093A000798) and eventually indicate such discrepancy to the user.
  • Figure 3 schematically illustrates a possible variant of the present invention, according to which the said key board is integrated in the dial 3 (or 3A) of the washing machine.
  • the dial 3 of figure 3 is in particular of the type able to take on two axially functional positions, i.e.:
  • said mechanical-kinematic means comprising for instance a mobile element having inclined planes and a spiral spring, are of the known type (generally known as push-push) and are already used on household appliances.
  • keys 12 that can comprise the previously mentioned keys 6 and 7, are of the type normally used with remote control units, or of the type in which the selection of the desired function simply takes place by simply touching the actual key, without the necessity of excessive pressure; naturally appropriate means are provided for the connection of such keys to the control system.
  • selection dial 3 or 3A could be substituted with a suitable cursor, i.e. a linear movement selector rather than an angular movement selector.
  • Such various options can be managed by the mentioned infra-red remote control, or by way of the mentioned key pad, being integral or not to the dial 3 or 3A, that is substantially the same as that of the remote control.
