Definitions

  • the present invention refers to an improved kind of clothes washing or drying machine, preferably of the type intended for use in households, adapted to perform washing or drying cycles that are in a particular manner intended to adhere to and comply with the user's preferences in as close as possible manner.
  • Clothes washing machines are generally known in the art as being washing appliances that are capable of performing working cycles, i.e. washing programmes, in accordance with operating instructions that are entered each time by the user.
  • Such operating instructions are basic, very simple ones, relating generally to those process characteristics or parameters that have a direct influence on or directly affect either the actual performance of the machine in terms of ultimate washing or rinsing results (eg. the degree of soil to be removed from the clothes, the type of fabrics involved in the operation, the spin-extraction intensity, and the like) or, more generally, the way in which the machine goes through the required operating cycle (energy usage, time to complete the cycle, and so on).
  • clothes washing machines of this kind are not capable of providing any indication relating to some of the operating or process parameters that are a consequence of the particular control settings, i.e. the particular commands entered by the user, so that the latter is practically in a position in which he/she has to set the controls almost “blindly”, in the sense that he/she has to rely solely upon his/her ability in setting the controls in a properly accurate manner based on his/her being more or less familiar with the ways and modes of operation of the machine.
  • an inconsistence may exist if a command is entered for the machine to perform an intensive washing programme at a very low temperature of the washing liquor, since an intensive washing programme is specifically intended for use in connection with heavily soiled washloads that require being generally handled with hot water, i.e. at a very high temperature of the washing liquor.
  • washing woollens which is largely known to require a special cycle involving particular process parameters—at a very high temperature of the washing liquor, which is certainly not the ideal one for handling woollens.
  • Still another example relates to the economy of the selected cycle.
  • a given washing result on a given washload may be obtained both with a prolonged washing cycle performed at a low temperature and with a quicker, shorter washing cycle performed at a much higher temperature and, therefore, at a much higher cost.
  • the ability to select in a proper manner in such case is by no means unimportant, since the user might be in a position as to decide to select either one or the other of these cycles depending on his/her own particular preference and the particular circumstances existing at the moment; for example, under normal circumstances a user is quite likely to decide to select the most economic one between the two cycle options, whereas the quickest, i.e. shortest cycle would be the preferred option in certain other cases, notwithstanding the higher cost penalty.
  • the final process parameters of the machine eg. the spin-extraction speed, the washing temperature, the type of clothes in the washload, and so on
  • additional information which—as appropriately processed by the control unit of the machine—contributes to a more accurate definition of the washing cycle to be performed.
  • Machines of this kind can certainly be considered as a significant improvement, since they actually enable the user to at least partly define the desired priorities.
  • the user fails to be appropriately informed in advance on which effects his/her settings or selections will actually bring about, i.e. which results can ultimately be expected from the particular selection made by him/her, so that he/she is practically unable to intervene in order to modify the settings accordingly, in the case that these turn out to be inappropriate in view of his/her preferences, priorities or requirements at that particular moment.
  • FIG. 1 is an overall, exemplary overview of the various variables and the states which each one of such variables can take;
  • FIG. 2 is a schematical view of a logical and symbolical flow-diagram of the operating mode of the present invention
  • FIG. 3 is a schematical view of a logical and symbolical flow-diagram of an improved operating mode of the present invention.
  • a clothes washing machine comprises a plurality of variables that can be commanded, i.e. controlled in a variety of manners so as to take different, independently selectable states.
  • the variables that will be considered here are the information pieces entered by the user concerning both the characteristics and properties of the clothes loaded in the machine for washing and some operating modes and parameters of the machine itself.
  • variable “1) type of fabrics” can take following states corresponding to the different nature of the fabrics constituting the washload:
  • variable “2) Type of washing process to be performed” can be selected according to one of following distinct states:
  • FIG. 1 gives a general, although by no way limiting overview of the various variables and the related states, which each one of such variables can take.
  • k1 is the number of possible states of the first variable
  • k2 is the number of possible states of the second variable
  • kh is the number of possible states of the H th variable, and wherein C indicates the number of said possible combinations.
  • Each control for each state of each variable is connected to a central control, storage and processing unit (not shown) that is adapted to perform an identification of each combination being set, i.e. selected by the user through the controls commanding said variables.
  • said control unit Upon having so selected the desired settings for the states of the various variables, said control unit identifies which one among the C possible combinations has been selected.
  • This identification and recognition process can be most easily be carried out using largely known data processing techniques and means.
  • control, storage and processing unit is also provided with a memory, in which there are stored C groups or sets of distinct data.
  • Each one of these groups or sets of data comprises all machine instruction statements (parameters) that must be used by a common operating programme to carry out a distinct washing cycle.
  • Each one of these groups or sets of data further comprises, eg. in a separate storage register, a respective one of said combinations C.
  • FIG. 2 From a logic point of view, the operations that are carried out are shown schematically in FIG. 2 , where only the first tw blocks and the last two ones, i.e. IF and START, are actuated, set or controlled by the user by selecting the states of each variable (in other words, the user tells the machine what he/she prefers), whereas the following blocks are automatically executed by the machine.
  • the user sets one or more desired states referring to respective ones among the cited variables, such as type of fabrics, kind of washing process, spin-extraction speed, and the like;
  • the user upon having completed the above-noted selection, the user enters—with the help of generally known, conventional means—an appropriate command that is read by the machine as an information that the preceding selection step is complete and it must therefore switch over to the subsequent processing step;
  • machine instruction statements which, when imported and executed by a washing programme of a general type, but pre-arranged so as to be capable of importing said machine instruction statements (machine operating parameters), will enable the same washing programme to be tuned up and integrated to include all data and instructions required to allow it to fully and optimally adhere to the particular process conditions selected by the user in accordance with his/her preferences;
  • each one of the above-mentioned groups or sets of data includes—further to the afore-defined machine instructions—also a second set of data, which shall be referred to as user data hereinafter (and which are referred to as “responses” in the appended claims).
  • user data are contained in appropriate storage registers associated to respective combinations, and provide respective information concerning the operating modes of the machine.
  • the above-mentioned processing and control unit is also adapted to select and retrieve—in a way that is fully similar to the one used to select and retrieve the afore cited machine instructions, and upon the user having duly selected the various states of the variables—said user data, as well as transfer them onto appropriate display means for due user information.
  • the latter can confirm the settings entered by him/her by actuating a proper control 5 provided on the machine; otherwise, even these settings can be cancelled and the above-described procedure can be gone through iteratively.
  • the controls used to cancel the settings entered by the user, or to confirm them may be of a fully conventional kind, so that they shall not be described any further here.
  • the present invention is essentially based on the capability provided by said control, processing and storage unit of converting the information concerning each single combination of user-set states into a corresponding—since recognized as such—group or set of machine instruction statements (machine operation parameters) to be used in the washing cycle.
  • the present invention allows for a number of further improvements to be embodied: in fact, the user can set one or more states of respective variables, but may intentionally decide to avoid considering other variables, simply because he/she is not interested in defining specific preferences or priorities in connection therewith.
  • control, processing and storage unit is provided with standard default instructions, which are acquired as machine instruction statements (machine operation parameters) instead of the definition of the state(s) of the variable(s) that the user failed to define, and the procedure then goes on in the same way as illustrated above.
  • the command informing the machine to go on with the above-specified procedure even in the absence of a proper definition of the state for each variable, may be entered by using the same INPUT control as indicated above.
  • a further, advantageous improvement is allowed for by the present invention to cater for a particular circumstance; it must be in fact considered that—not only in theory, but also in practice—it may well happen that not all states that can be set by the user for the various variables turn necessarily out as being compatible with each other; as a matter of fact, it may occur that some settings turn out as clashing with each other, i.e. contradicting each other.
  • Another case in point would be the one arising when a washing cycle of the “INTENSIVE WITH PRE-WASH”-type is selected along with a washing temperature set on COLD.
  • this further improvement enables such incorrect or unsafe operating modes to be unfailingly and automatically prevented from being executed even if the user happens to accidentally or unintentionally set the related states.
  • the above-mentioned improvement consists in ensuring that, whenever any of such “impossible” combinations is selected, the machine instruction statements (parameters) corresponding to these particular combination are programmed to process and work out the condition of impossibility for any viable washing cycle to be performed, and the corresponding information is conveyed outside for the benefit of the user by means of appropriate, possibly visual display or warning means.
  • the machine may also be programmed so as to automatically stop, and switch over to a condition in which it is unable to perform any cycle at all, until a new combination of states concerning respective variables, and pre-defined as “acceptable”, is eventually set and entered.
  • a still further improvement can be easily embodied in the following way: with reference to FIG. 3 , this can be noticed to describe a quicker operating mode for selecting the various combinations and operation options and being immediately capable of taking notice of the “expected” result of such selection as processed out by the machine.
  • first block 11 there is again performed a selection of the states of the respective variables, as this has already been set forth with reference to FIG. 1 .
  • second block does however no longer represent an INPUT-type command to activate the machine, which is on the contrary provided with automatic processing means adapted to be readily activated by the simple command relating to the selection of the states of respective variables, even when just a single state is selected.
  • the machine automatically processes the related command and, on the basis of previously entered selections or, if no selection has already been entered, on the basis of the afore-mentioned default selections, works out a result that is automatically displayed as user data 12 , in a similar manner as in the afore considered case, however with the difference that, in this case, owing to the fact that the selection data are processed on a real-time basis, the man-machine dialogue, i.e. the dialogue between the user and the machine is a continuous and immediate one.
  • the user proposes his/her own preferred selections and, each time that a selection is entered, the machine immediately processes the related command and responses in an equally immediate manner by proposing the respective user data.
  • a decisive advantage deriving from such solution lies in the fact that the user is given the possibility of checking and accepting the results of his/her selections as soon as they are entered individually, i.e. before a cycle start command is eventually entered.
  • the machine in turn proposes a cycle involving:
  • the machine will propose a 60-min. washing cycle with a slightly higher water usage (in view of making rinses shorter), while the performance data change as follows:
  • Washing action Slightly soiled (the washing perfomance is scaled down to a lower class: less washing action)
  • Energy usage Normal (energy usage is scaled up to a higher class: more energy used)
  • Rinsing performance Sufficient (although the amount of water is increased, the rinsing performance will be not better than sufficient, since time is too short)
  • the machine will answer by proposing a 70-min. washing cycle with a water usage of 70 litres and following performance data:
  • Rinsing performance Good (rinsing performance is scaled up to the immediately higher class)
  • the present invention is fully applicable to other laundry machines, such as clothes dryers, provided that the variables and the related states being set or selected refer to programming modes and schemes that are typical of these machines (eg. type and amount of clothes in the drying load, final moisture content or degree of dryness desired, and so on).
  • the corresponding user data will be such as to generate indications that are effective in enabling the user to come to an appropriate final selection of the instructions to be entered, eg. the time required to complete the cycle, the energy usage, and the like).
