The present invention relates to a laundry washing or washing/drying machine with speech recognition and response capabilities, in particular speech response, and a method for operating thereof.
The problem has always existed of washing a laundry mixture composed of different types of clothes without damaging the individual items of laundry, such problem has been a challenge for designers of laundry washing machines. An example of a solution to this technical problem is given by the German patent application DE 39 10 763 in the name of Licentia. Even if the washing machine described in said German patent application has speech recognition capabilities, quite advanced at the time of filing this application, 1989, the problem of washing a mixture of laundry composed of different type of clothes is solved in a very poor manner and even today has not been solved in a satisfactory manner. In fact, in the presence of different types of laundry, like bed linen, towels, colored cotton items, undergarments and the like, the washing program, selected by the washing machine, provides for making the most delicate treatment in accordance with the most delicate category of laundry inserted in the tub of the washing machine, i.e. undergarments or colored cotton items.
In other words, even if together with a silk shirt bed linen is among the items to be washed, that normally requires a much more thorough washing program, such as 90°, the program selected by the machine is the one that, from among those that could be the most appropriate for the different type of laundry, guarantees the washing temperature, or the agitation of the clothes in the tub, or the drying spinning speed, or the quantity of detergent, or all of the above, which is the lower one in relation to the most delicate item inserted in the tub.
It is to be noted that the solution, given from the German patent application, i.e. that it is enough to have a wash program including a pre-wash, in order to ensure an intense cleansing action, does not work. In fact every person skilled in the art of laundry washing machines knows that the three principal factors influencing laundry washing are: temperature, agitation of the items, and detergent. If the temperature, or the agitation, or the quantity of detergent are not sufficient, laundry can be washed even for a very long period of time, but the result will still be very poor.
A further solution of the prior art system is given by US 2001/042391 in the name of BSH Bosch Siemens that comprises an automatic washing machine that is able to propose a washing program to a user based on the typologies of fabrics placed within the drum machine by way of a spectrometer sensor. However the technology of using a spectrometer sensor for determining a washing program does not provide an advantageous solution for the user, inasmuch such sensors are only able to recognize the fabrics of the items and not the items themselves. This system obviously has drawbacks inasmuch as cotton fabric, for instance, may be used for bed linen, shirts, undergarments, handkerchiefs, etc. and the machine would only recognize the fabric as being cotton and then propose a program based on such typology of fabric. It is known that bed linen, shirts, undergarments and handkerchiefs require distinct washing programs. Moreover, this solution does not take into consideration the level of dirtiness and the color degree (intensity) of the items introduced in the drum of the wash-tub.
It is therefore an aim of the present invention to indicate an automatic laundry washing machine with speech recognition and response capabilities, in particular speech response and a method for operating thereof which do not suffer the drawbacks of the prior art.
This and other aims of the present invention are reached by way of an automatic laundry washing or washing/drying machine with speech recognition and response capabilities, in particular speech response and a method for operating thereof as claimed in the annexed claims that constitute an integral part of the present description.
In synthesis, the fundamental idea of the present invention relates to a laundry washing or washing/drying machine (1) comprising:
The present invention also refers to a method used for controlling the above said automatic laundry washing or washing/drying machine.
Further objects, features and advantages of the present invention will become apparent from the following detailed description and from the annexed drawings, which are supplied by way of a non-limiting example.
It is to be understood that the figures and descriptions of the present invention have been simplified to illustrate elements that are relevant for a clear understanding of the present invention, while eliminating, for purposes of clarity, many other elements which are conventional in this art. Those of ordinary skill in the art will recognize that other elements are desirable for implementing the present invention. However, because such elements are well known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements is not provided herein.
The present invention will now be described in detail on the basis of exemplary embodiments.
With reference to
The output means 5, 6 can comprises a loudspeaker 5 and/or a display device 6, such as a LED/OLED display panel or similar, for interacting with the user in relation to the washing cycle selected by the automatic laundry washing or washing/drying machine 1 in relation to the items loaded within the wash tub.
As an alternative, it is possible to replace both the HID controller 3 and the display device 6 with a single touch screen display also equipped with a loudspeaker 5 and microphone 4 (not shown in the drawings), which can provide the same functionalities in a single device without departing from the teachings of the present invention.
With reference also to
The control unit 2 comprises the following elements:
that, in a variant of the present invention, a user of the machine 1 can manually input the typology and the characteristics of the items loaded in the wash tub of said machine 1;
Data management means 21 are simply indicated in the figure with the symbol CPU.
As an alternative to the communication bus 20, it is possible to connect the above-described components by means of a star type architecture, without departing from the teachings of the present invention.
In order to allow user-machine interactions, the washing or washing/drying machine 1 also comprises a microphone (microphone means) 4, suitable for transforming the speech of a human user in electrical signals apt to be managed by the control unit 2, so that it allows the user to vocally interact with said machine. In this way, the user may operate the machine 1 in a hands-free way.
For allowing voice interactions and speech recognition, the control unit 2 also comprises the following elements:
communication with the loudspeaker 5, so as that the control unit 2 can generate audio and/or vocal responses which can be heard by the user. The user can also control the volume of the audio and/or vocal responses through traditional means;
wherein both the audio converters 24, 25 and the display controller 26 are in communication with the other elements of the control unit 2 preferably by means of the communication bus 20.
Operation of the automatic laundry or washing/drying machine 1 with speech recognition and response capabilities, according to the present invention results in being both rapid and user-friendly thanks to the above-described elements.
The washing or washing/drying machine 1, when using the speech recognition facilities of the invention, would enable a user to individually load the washing machine item by item as follows:
As said before, these essential pieces of information are the ones that influence the performance of washing programs of the machine 1. In fact, if items having very different typologies and characteristics are put together during a single washing program, the most delicate items, which require a delicate washing program, may be damaged.
By way of example, the user, during the loading process of the tub, can enounce or indicate the following list of items:
With this information, the washing machine 1, based on its control unit 2, will be able to automatically calculate and determine the appropriate or best washing program from those available in the memory means 22 of the machine. These programs have been tested several times by the machine manufactured and memorized in a list of possible programs.
In a particular embodiment of the invention the washing programs memorized in the memory means 22 can be periodically updated through an interface, for instance using a USB port or a Wi-Fi connection or a wireless connection or the like in order to provide the user with a set of washing programs that are always the best ones available in connection with the improvements of detergents and/or energy saving rules and/or new washing tests made by the washing machine manufacturer.
As a possible further variation or feature of the invention, the washing machine 1, byway of an LCD screen or machine produced voice, can instruct the user how much detergent and softener to insert in the appropriate compartments of the machine or to take them automatically from an internal dispenser for several washes, or asking or suggesting the user if a drying process is required or the like, thus creating a true man-machine interaction.
The proposed washing or drying/washing machine 1 has the characteristic feature to instruct the user to remove a certain piece of laundry, previously identified thanks to the human interface device 4 apt to receive by the user information regarding the items to be washed, in particular the speech recognition facility, and inserting into the tub the laundry, item by item, in order not to jeopardize the quality of the wash or damage the contents of the load when all the items put together in a single wash cannot be properly washed together.
For instance, if the above-mentioned wash load is enounced or indicated and loaded in the tub of the machine 1, the output means 5, 6 will inform the user to remove the pair of intense color blue jeans.
In another example of operation of the machine 1, the user, during the loading process of the tub, can enounce or indicate the following list of items:
After the above-mentioned wash load is enounced or indicated and loaded in the tub of the machine 1, the output means 5, 6 will inform the user to remove the lightly soiled white silk blouse and the a lightly soiled red woolen sweater.
More examples of erroneous wash loads can be made. All of them however share this common critical point: the essential pieces of information characterizing each item inserted in the wash tub of the machine 1 allow for recognizing in the wash load the presence of laundry items that cannot be washed properly. This also means that, if a proper washing of all the items has to be obtained, some conflicting items should be removed, otherwise they will be certainly damaged.
In order to make possible the use of the automatic laundry washing machine 1 even by people who are not able to or do not want to take advantage of the speech recognition method according to the invention, the user can load the tub without enabling speech recognition, as per traditional washing machines.
Summarizing, the laundry washing or washing/drying machine 1 comprising:
wherein the user introduces into the wash tub the items to be washed, specifying for each item essential information comprising a typology (bed linen, shirts, underwear, etc.) and a description of its characteristics, in particular the type of fabric, the degree of soil, the color and its intensity, said essential information being given by the user through said human interface 4, memorized in said memory means 22 and used for determining the most appropriate washing program among said set of washing programs, chosen taking into account the items singularly specified through said essential information when they are introduced in said wash tub and wherein the data management means 21 are also configured for reporting to the user, by means of said output means 5, 6, the presence of at least a conflicting laundry item into the wash tub, after having determined on the basis of said essential information which conflicting laundry item is unsuitable to be washed by means of the selected washing program.
With reference also to
the above mentioned operational mode described and applied to the automatic laundry washing machine 1 according to the invention, also comprises the following states:
When the washing machine 1 is in a working condition and the speech recognition is enabled, the control unit 2 enters in the state S1.
During the time in which the washing machine 1 remains in this state S1, the washing machine verifies that an item of laundry has been introduced by the user and that a vocal description of the item introduced has been provided (option block C1), for example considering that the procedure for introducing items of laundry is finalized when the user inputs a command, such as “Start Wash”, either vocally by way of the microphone 4, or manually by way of the keyboard 3, or by way of a dedicated key, such as a Start key, not illustrated in the FIGS.. In the case in which an appropriate command, such as “Start Wash” has not been entered by the user, the method returns to state S1, and the previously inputted essential information identifying the laundry item, if any, is stored in the memory means 22. On the other hand, if the machine successfully recognizes a user command, such as “Start Wash” the washing machine 1 will pass on to the successive state S2 and select the most appropriate washing cycle/program from its internal memory 22, based on the items of laundry introduced and vocally, or manually described, item by item, by the user. Before initiating the appropriate washing cycle/program, the washing machine 1 calculates whether the user has introduced an item or items of conflicting laundry that could jeopardize the washing cycle/program and/or damage the laundry (option block C2). If the control unit 2 of the washing machine 1 identifies the presence of conflicting laundry item(s), it will instruct the user to remove the conflicting item(s) byway of vocal/visual instruction, announced through the loudspeaker 5 and/or text messages displayed on the display panel 6. The washing cycle/program will not initiate until the control unit 2 is satisfied that the conflicting item has been removed; the user would confirm removal by way of inputting a vocal/manual command, making use of the microphone 4, or by manually inputting confirmation of removal, byway of the keyboard 3, answering a Yes/No type question relative to the conflicting item being removed announced through the loudspeaker 5 and/or displayed on the display device 6. When the control unit 2 is satisfied that the conflicting item of laundry has been removed, the machine will go into state S3 and the most appropriate washing cycle/program for the items of laundry introduced by the user (and present into the wash tub) will initiate. It is to be noted that during the operational process described herein, the washing machine will interact with the user, either vocally, by way of the loudspeaker 5 and/or the display device 6, asking and/or suggesting processes, such as “Add soap/detergent”, “Is softener necessary”, “Start drying cycle at the end of the washing cycle”, etc. It is moreover noted that the detergent and/or softener may be manually introduced by the user or be automatically measured and introduced during the washing cycle by way of appropriate internal dispensers.
After the activation state S3 is finalized, the washing machine 1 will exit the operational procedure and end the cycle by automatically turning itself off.
Summarizing, the method for operating a laundry washing or washing/drying machine 1 according to the invention comprises the following phases:
Assuming that in a wash load there are NI items and the machine 1 can select between NP available washing programs, the conflicting items can be found (during the phases a., b. and c. of the above-mentioned method), for instance, by means of an algorithm that executes the following phases:
The proper likelihood functions for operating the laundry machine 1 in a proper way should be provided by the manufacturer of said machine 1.
The skilled person may use a different algorithm from the one described above without departing from the teachings of the present invention.
The use of an operational procedure as described herein above allows for creating a simple, user friendly washing cycle/program wherein the user can instruct the washing machine 1 vocally and the washing machine can interact with the user whenever necessary with questions and/or instructions.
Technicians of the art may use a different recognition interface with regards to that described hereinabove, without however for this departing from the teachings of the present invention. For instance in the above description reference has been made to a washing machine where the wash tub is provided with an internal drum for accepting items to be washed. It is clear that the invention also works in the case where instead of a drum, the wash tub is provided with an agitator or similar means for washing items.
The technician of the art may be able to create an automatic washing machine 1 incorporating selection of a washing cycle/program based on the identification of individual items of laundry different from that described hereinabove, without for this departing from the teachings of the present invention.
In fact the basic concept of the present invention is the fact that through the identification of the typology and the different characteristics of the items to be washed, made item by item, it is possible to ascertain if, in the mix of items loaded in the wash tub of the machine, there are conflicting items which render impossible to perform a good washing program or can damage one or more of the loaded items. In this way, the user can be informed of such situation by announcing or displaying which items have to be removed, in order to perform a good washing program without incurring in the risk of damaging some of the items to be washed.
In a variation of the invention, the user may be able to store habitual washing programs in the internal memory means 22 of the washing machine 1 and allocate a dedicated program phrase, such as “Wash Cycle One”; upon calling the stored washing program the washing machine 1 would interact with the user, either vocally, by way of the loudspeaker 5 or by way of the display panel, with a list of laundry items associated to such stored program and wait for confirmation from the user before initiating the desired washing cycle/program. In any case, in presence of items in conflict with the type of selected program, the machine will inform the user about the fact that this/these item/s cannot be washed properly, and has/have to be removed from the wash tub.
The operational procedure, system and method described herein by way of an example may be subject to many possible variations without departing from the novelty spirit of the present idea; it is also clear that in the practical implementation of the invention the illustrated details may have different devices or be replaced with other technically equivalent elements, as well as providing different sequences or steps.
It can therefore be easily understood that the present invention is not limited to the above described machine, system and method, but may be subject to many modifications, improvements or replacements of equivalent parts and elements without departing from the inventive idea, as clearly specified in the following claims.
While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of the inventions as defined in the following claims.
The present application claims priority from International Patent Application No. PCT/EP2013/071597 filed on Oct. 16, 2013, the disclosure of which is incorporated herein by reference in its entirety.
