Abstract

Described and illustrated is a washing machine for cleaning or treatment of textiles with the aid of the washing machine be supplied detergent, comprising a control unit, characterized in that the washing machine is associated with a detection device which detects information about the washing machine supplied textiles or the washing machine supplied detergent and to the control unit, wherein the control unit determines an appropriate washing program based on the information transmitted.

Description

The The invention relates to machines for cleaning or processing of textiles or crockery as well as corresponding textiles and containers Pickup, storage and transport of cleaning agents.

at The machines are washing machines for the Home or professional use and dishwashers.

Appropriate Household washing machines are available in almost every private household. These washing machines have in addition to a laundry drum Accommodating textiles usually a filling area for the supply of detergent as well as one or several controls for manually setting different Washing programs on.

in this connection It can happen that a washing machine user inadvertently Set a wrong washing program for a particular type of laundry. Thus, it can happen, for example, that textiles too hot be washed and shrink. Such a misoperation by The user may accidentally, as well as due to lack of Knowledge.

Furthermore There is a problem that the user of the washing machine at choice a wrong wash to a certain wash can. In this way, for example, a sensitive type of textile with a particularly aggressive detergent active in contact come, which lead to a destruction of the textile fabric could.

outgoing from the known prior art, the object of the present The invention is a system of a machine for cleaning Textiles or crockery, corresponding detergent containers and, where appropriate, appropriate textiles to provide an easier and safer implementation of a Washing process allows.

The Invention solves this problem according to a first aspect with the features of claim 1.

The Principle of the invention is according to the first Aspect is to provide a washing machine, which to a independent investigation or independent Collection of wash-related data is capable. A user needs the corresponding information of the washing machine thus no longer directly, for example via a wash program selector switch, feed. The washing machine provides the required information rather self-determined.

On The washing machine can then enter the basis of the determined data the imported laundry, or the supplied Select or calculate detergent, adjusted washing program and for the implementation of the appropriate washing program necessary parameters (for example regarding washing time, Water temperature and rotation frequency of the laundry drum).

Of the Washing machine is assigned for this purpose at least one detection device, what information about the laundry supplied to the washing machine or the detergent supplied to the washing machine or determine the washing method to be used. The detection device For example, optical, electromagnetic or electric Readout and evaluation include.

For example For example, the detection device may comprise a barcode scanner, which is arranged on or in the washing machine. The washing machine To be supplied detergent can be in a detergent capsule be arranged, which, for example, in the manner of a known Household press capsule system in a washing machine side recording is insertable. The barcode can be placed on the capsule and information about the contained in the capsule Detergent included. Inside the washing machine, the detergent capsule can be kept and read by the barcode scanner.

The This information can be determined, for example Information on the composition, nature or quantity of the have the detergent capsule arranged detergent, or also information about the use of the detergent, for example in the form of a washing program recommendation.

For a corresponding information acquisition needs the detergent but not encapsulated packed and brought into the washing machine to be. It is equally conceivable that a loose packaged detergent, for example on the outside the packaging attached or as an information element in the form of a machine-readable leaflet, coded information attached are. So a user can put the loose detergent in a receptacle Insert the washing machine while keeping the packaging Manually attached barcode information to a barcode scanner lead past.

The In particular, washing machine can do the information automatically capture, for example, as a result of a coupling process of a detergent container to a washing machine, in which a corresponding optical evaluation device is automatically triggered.

Instead of Of course, the washing machine can use an optical barcode scanner also have any other detection devices. Especially here are so-called RFID systems (Radio Frequency Identification) to call, in which a corresponding detergent container has the information in the form of an RFID transponder. Washer sided can be mounted according to a reader, which the, in particular factory-registered in the transponder, information at an approach of the transponder or the detergent container can automatically read to the washing machine.

Also Electrical detection devices are conceivable, in particular in cases where the detergent containers are formed on the washing machine attachable.

The Washing machine can alternatively or additionally also a Detection device, which information about determines the textiles to be washed or processed. For this For example, the washing machine can be in the area of its laundry drum or whose access opening has a sensor system which Information about the textiles introduced into the washing machine drum collects. During a filling process of the laundry drum For example, a user may attach one to the textiles Information carrier manually on a corresponding reader within pass the laundry chamber opening. For this can in particular a certain orientation of the information carrier be necessary relative to the detection device, for example for barcode scanners. Alternatively, of course, RFID systems applicable, which do not require a corresponding orientation.

Around the degree of pollution of imported textiles too determine, is in particular a purely optical detection device conceivable, which images of imported laundry created and by an evaluation of these images with the help of special Image recognition software, for example, the degree of pollution or the color of the imported laundry (white wash, Coloreds).

The Information determined by the detection device is detected Acquisition is transmitted to a control unit, which in particular together with the detection device as a common component or alternatively, in particular in several Detecting devices, spaced therefrom as a separate component can be trained.

information can be over well-known Transfer data paths from the detection device to the control unit which enables the control unit to have a proper wash program to determine. The control unit can, for example, to a predetermined Selection of already preselected and inscribed in the control unit Resort to washing programs. Alternatively, the control unit a washing program also on the basis of the transmitted data, in particular modular principle, self-assemble.

The The wash program determined in this way can then be used by the control unit be set directly, so that the user, for example, only still a start or an on / off button to press needs. Alternatively, this switch can be omitted, so that the washing machine control automatically determines the determined washing program, in particular timed, activated. In this way, the Ease of use of the washing machine according to the invention be particularly improved because of washing machines from the state known in the art program selector switch for different Washing programs can be omitted.

One However, such selector switch can of course additionally be provided, for example, in the event that the User with the washing program determined by the control unit contrary to expectations is not satisfied. The control unit can be the user suggest a specific washing program and, for example, about show a digital display. The user can then contact these Recommendation or also another washing program manually over select the selector switch.

Provided both the textiles to be imported and the textiles to be imported Detergent each having a detection device is assigned, can be checked by the control unit, whether the imported detergent to the imported Textiles fits and possibly a warning, for example in the form of a beep, to be sent out.

The described washing machine can be used particularly advantageously in the supply of separately encapsulated detergent, since encapsulation may be accompanied by a portioning of the detergent which is tailored to the needs of the user. Thus, the user can determine the amount of detergent used over the size of the detergent capsule guided detergent and the washing machine indirectly, via the detection device and the control unit, tell what amount of laundry is.

When Detergent or active ingredient in the sense of the present patent application different substances, for example liquid, gelatinous or powdery (also pressed) form, which for cleaning textiles but also for example for treating used the water used. This includes in particular Heavy-duty detergents, colored laundry detergents and laundry and fabric softeners, but also water softener, bleaching salt and the like Substances. As a detergent or drug but further Also understood as constituents of a detergent to be mixed, wherein a corresponding detergent container, for example may contain a substance which is mainly certain Enzymes, surfactants, catalysts, bleaches and / or similar Has detergent ingredients. In addition, as a detergent or Substance also understood substances, which are generally chemical Equipment can be designated. These include in particular bleaching, dyeing and impregnating agents, Fragrances and finishes, ie agents which essentially one Processing of imported into the laundry drum Serve textiles.

The Detergent can be fed directly to the washing machine be introduced by, for example, in a capsule-like form in the washing machine is, or alternatively, the detergent may also have separate Supply lines are supplied. This is especially true for industrial applied washing machines necessary, which spatially separate from the washing machine coupling points for detergent containers exhibit. These interfaces can then, for example be assigned optical or electromagnetic readout devices.

alternative there is a possibility that the coupling points are so Located close to the washing machine are the range of a in the washing machine arranged RFID reader to the coupling point and an attached there, an RFID element having detergent container ranges.

The Washing machine according to the invention has a detection device on, who can determine the information, either on the textile arranged or assigned to this, or to a detergent or arranged a container for the detergent or can be assigned to such a container. In the event that the information is in a Transponder stored on the textile can, after receiving the Information the control unit, for example, based on the received Information, eg. B. aware of the nature and condition of the textile, a detergent made up of several different ingredients or active ingredients to optimize the washing effect or in the sense of an optimized Mix treatment together.

According to one advantageous embodiment of the invention takes place the detection or detection of the information by the detection device automatic or automated. This allows for a special comfortable handling of the washing machine. The user needs this involves the collection of detergent information or textile information especially not to worry at all. For example can be a collection of detergent information during one or after an introduction of a detergent capsule in a corresponding washing machine side recording, due to a mechanical contacting of a machine-side trigger or as a result of the activation of a corresponding light barrier, respectively.

According to one further advantageous embodiment selects the Control unit the wash program due to the transferred Information from a bevy of given washing programs. This is particularly advantageous because such a procedure only small claims to the computing power of the control unit. It can various preset washing programs are written in the control unit become. Such programs can for example by a Users or a technician can be updated at any time. Therefor a corresponding interface may be provided, in particular Connected to an in-home wireless network for wireless Control of various household appliances.

alternative it is envisaged that the control unit will start the washing program the transmitted information itself. Here can the control unit receives the information obtained, such as the concentration of the introduced detergent, the type of imported textiles, etc., process such that they have the necessary washing parameters, such as the duration or the frequency of the tumble drum revolutions, stepless can regulate without having to observe the prescribed washing programs are.

According to a further advantageous embodiment, the detergent container, which has the detergent, can be introduced into the machine. This allows a particularly advantageous assignment of the detergent container to the washing machine. The detergent container can basically be closed and opened during the coupling process of washing machine side opening means be bar. In this case, the detergent container can in particular be completely introduced into the machine. The detergent container may be formed in particular as a capsule.

alternative The detergent can also be partially removed from the washing machine protrude, for example, when the detergent container bottle-shaped is formed and with the help of a bottle-side screw thread and a washing machine side Gegenschraubgewindes on the washing machine can be coupled.

According to one further, particularly advantageous embodiment the detection device on the washing machine differently shaped insertion openings assigned for detergent containers. To this Way, a particularly advantageous coding and detection of Detergent information allows. The washing machine This can be different shots, each with different opening shapes a user having the detergent in corresponding Can buy forms packaged. For example, a corresponding Packaging round, rectangular or star-shaped be, with the appropriate washing machine openings also round, rectangular and star-shaped are. The user thus stands for every type of detergent a separate insertion opening available. The detection device can determine which insertion opening has been used by the user and thereby on the imported detergent back close. Accordingly, the control unit determine a suitable washing program.

The Invention solves the task according to a second aspect with the features of claim 16.

Therefore has a detergent container coupled to the washing machine a coding which is readable by the washing machine. The Coding can have different shapes.

she can, for example, as already described, in the form of an RFID chip or a barcode.

alternative a corresponding coding of the color of the detergent container to be provided. For example, different colored detergent capsules are provided, which each have other detergents or detergent ingredients. For example, a detergent for Weisswäsche packed in a white detergent capsule, colored laundry detergent for example in a blue capsule and washing machine descaler for example in a gray capsule. The appropriate color scheme can of washing machine side sensor elements, for example an optical detection element, detected and evaluated. A color coding is further also with respect to individual Areas of detergent containers possible, so z. B. by color stickers, which are only part of a Cover detergent capsule. The coloring must therefore not necessarily concern the entire detergent container.

Instead of Furthermore, a color coding is also a shape coding vornehmbar. For example, in their cross section triangular, round or rectangular detergent capsules provided be, which, for example, different washing machine side associated with shaped openings. The washing machine, but also their users can therefore on the Form the capsule on their contents infer. However, this does not rule out that the detergent capsule additional uncoded information for the user has, for example in the form of a labeled label. A Coding means in this sense that the required Information provided by the detergent container that they can be recorded and evaluated on the machine side.

The For example, information can refer to the Composition of the detergent contained, but alternatively for example, on the use of the detergent, for example based on a coded present washing recommendation, or the amount of the detergent. So are different sized detergent containers the same shape imaginable, which in the same recording of the washing machine can be introduced. Detergent-side detection devices can then be the size of the detergent container on the amount of detergent and thus on the amount of to infer the textiles to be washed. For example For example, a first detergent capsule could be designed in this way be that they take up a single serving of detergent, for example, is designed for a single household. Another detergent capsule could be twice as large be to take twice the amount of detergent, and that Allow washing of twice the amount of textiles.

ever according to the amount of textiles to be washed, the user can choose one of the use both capsules and tell the washing machine this way, the amount of textiles to be washed.

According to a particularly advantageous embodiment of the invention, the detergent a closure element, which is designed such that it is automatically openable during or as a result of a coupling process with the machine of the washing machine associated with opening means. This allows a particularly comfortable design of the washing system. In this way, a user does not come into contact with potentially highly concentrated and therefore hazardous raw materials of the detergent. This allows in particular a kind of parental control. For example, the detergent container may be capsule-shaped and have a membrane on one end face. This membrane can then be pierced or cut by a ram element associated with the washing machine.

According to a further particularly advantageous embodiment of the invention, the detergent container has a plurality of chambers separated from each other. This allows a particularly advantageous composition of the detergent. The detergent can thus be freshly mixed together just before the start of the washing process. The different chambers of the detergent container may in this case have different active ingredients of the detergent. Due to the multi-chambered capsule system, it is possible to specifically utilize a catalyst effect which occurs when different detergent constituents are mixed together. In particular, from enzymes existing biocatalysts, as for example from the US 5,876,625 Carnegie Mellon University are known to find use, which allows washing the textiles at very low washing temperatures. The washing process is therefore almost without heating or especially without heating. This is contrary to a washing machine with as few control elements as can be uniformly washed at approximately constant or completely identical water temperatures, especially cold.

Everyone the capsule chambers can each be assigned a separate coding be, so that the chambers in particular also modular principle to various detergent containers are composable. Alternatively, the detergent container also a common Coding, for example in the form of a barcode, for all have separated active ingredients of the detergent container.

The Invention solves the task according to a Further aspect with the features of claim 26. Accordingly, can also the textiles to be processed or cleaned have a coding. This can in particular of washing machine side sensor elements when inserting the textiles into the laundry drum be recorded. The coding used here contains at least an information about a material property of the textile product in coded, so machine-readable form. The corresponding Washing machine can determine in this way, for example, whether in the laundry drum only white wash or mixed colored laundry was introduced. Therefore is also the laundry color as a material property in the sense to understand the present patent application. Alternatively, for example, too the nature of the tissue can be understood as a material property. So For example, the washing machine can detect that the machine is in the machine only wool wash is located. In particular, it is conceivable that coding of a chemical equipment of a textile Information about the working method to be used etc. has.

The The information-containing element can in particular directly to be attached to the laundry, for example, usually a washing information having textile label. In particular, the element may consist of a Imprint, for example, such that on a corresponding Label a barcode printed with machine-readable information is.

alternative but does not need the element directly to the individual textiles It can be fixed, for example, in industrial laundries also be assigned to a group of textiles. The element can For example, on laundry baskets, moving clothes racks and the like, so that a corresponding washing machine, Information about the person to be cleaned or processed Laundry with the help of an RFID system already on approach the collected textiles to the washing machine can determine.

The Invention solves the task according to a further aspect with the features of claim 31. Accordingly a method is provided, which determines the detection or the acquisition of washing Data independently by the washing machine allows. With respect to the above device claims The statements made are essentially identical transferable to the procedure.

The invention solves this problem according to two further aspects with the features of claims 32 or 33. Accordingly, a dishwasher may be provided to which the above-mentioned embodiments in connection with a dishwashing agent container and dishwashing agent disposed therein, as well as dishes to be cleaned substantially identical are transferable. To avoid unnecessary repetitions is waived to separate explanations.

Further Advantages of the invention will become apparent from the non-cited subclaims as well as from the following description of the figures.

Of the The following description of the figures should be made in advance, that the clarity half the same or comparable parts or components partially provided with the same reference numerals, partly under Addition of apostrophes or small letters, too as far as different embodiments are concerned are.

The in their entirety with 100 designated washing machine is evidenced 1 designed as a household washing machine for home use. Of course, this embodiment is to be understood as a household washing machine only by way of example. Accordingly, the illustrated machine could also be a commercial washing machine or a domestic dishwasher.

The illustrated household washing machine 100 has a schematically indicated receiving chamber 110 for textiles, which may in particular comprise a laundry drum, not shown. The reception chamber 110 is from a reception door 120 lockable, as a result of its opening by a user textiles in the receiving chamber 110 can be introduced. At the household washing machine 100 is in the embodiment according to 1 , operable from the front, a receptacle 130 arranged for the introduction of detergents. This recording 130 is by opening a front door 140 accessible. The peculiarity of in 1 shown washing machine is that both the detergent absorption 130 as well as the textile reception chamber 110 one sensor element each 150 and 150 ' a detection device 400 assigned. The detection device 400 also has ductwork elements 160 on which the sensor elements 150 and 150 ' for information transmission with a control unit shown only schematically 170 connect.

The control unit 170 is configured to be independent of the sensor elements 150 and 150 ' received information about the in the washing machine 100 imported textiles and / or in the washing machine 100 introduced detergent can process so that they can select a suitable wash program for the upcoming wash and offer or set directly. This washing program can take into account various factors relating to the textiles and the imported detergent. For example, the degree of soiling, the fabric and / or the color of the in the receiving chamber 110 imported textiles and, alternatively or additionally, the composition or Amount of detergent introduced into the washing machine. In a memory of the control unit 170 For this purpose, various washing programs can be pre-laid, which are provided by the control unit 170 can be selected according to the transmitted information. Alternatively, the control unit itself can put together a washing program.

The transmitted information may initially be information regarding the recording 130 act imported detergent. This information will be as in 1 represented by the sensor element 150 determined.

This sensor element 150 can be proven 2 as within the recording 130 arranged scanner element may be formed. 2 shows how the scanner element 150 with optical means information about one in the recording 130 introduced detergent capsule 180 detected. The detergent capsule 180 points to a front page 190 a readable element 200 on, which is for example one on the front page 190 the detergent capsule 180 Bonded barcode can act. The sensor element 150 This can for example be continuously active and the recording 130 constantly monitor. In the event that a detergent capsule 180 in the recording 130 is introduced, it can then a corresponding readable element 200 to capture. Alternatively, it is also conceivable that the sensor element 150 is activated by separate mechanical or other elements, for example by light barriers.

In any case, the sensor element determines 150 automatically information about the detergent capsule 180 , For example, about the composition or amount of the detergent contained.

The detergent capsule 180 in this case, in particular, two different chambers 210a and 210b which may contain different detergent ingredients. So that the detergent ingredients in the chambers 210a and 210b do not react with each other before this is desired, the detergent capsule indicates 180 a capsule wall 220 on which the two capsule chambers 210a and 210b separated from each other vacuum-tight. At the capsule wall 220 it may be, for example, a membrane, which in particular also a part or the entire surface of the detergent capsule chamber 210a or 210b can surround.

The readable element 200 the detergent capsule 180 can advantageously information about both capsule chambers 210a and 210b contain. Alternatively, it is also conceivable that each capsule chamber has its own element 200 assigned.

The detergent capsule 180 is by inserting into the receptacle 130 The washing machine not only automatically readable but also automatically openable. The recording 130 this is an opening device 230 associated with the detergent capsule 180 for releasing the pre-portioned packaged detergent or detergent ingredients can be opened. The device 230 here has one about a pivot axis 240 swiveling two-armed lever 250 on. This includes an actuation end 260 , which when inserting the detergent capsule 180 in the recording 130 from the capsule-side actuating surface 270 will be contacted. The re 2 Counterclockwise preloaded lever 250 is at a retraction movement of the detergent capsule 180 taken in a clockwise direction, making one as a ram 280 trained area of the lever 250 the front side 190 pierce the detergent capsule and into the chamber 210b can penetrate. Thereby, the capsule is opened and access to the interior of the package, ie to the detergent or to the detergent ingredient in the chamber 210b provided.

After the detergent from the chamber 210b was removed, the detergent capsule 180 be rotated by a rotation mechanism, not shown, such that the opening means 230 Access to the other detergent capsule chamber 210a Has.

There are different possibilities here, the detergent or detergent ingredients from the detergent capsule 180 extract. In 2 is a water pipe 290 hinted, which partly in the lever 250 integrated and in particular by the plunger 280 passed through.

alternative it is also possible, at least one capsule chamber two places open and through the first opening Water and water through the second opening together with the dissolved detergent or detergent ingredient deploy.

In the illustrated embodiment is through the water line 290 introduced both water and water with the dissolved therein detergent from the detergent capsule 180 applied.

Finally, it is also possible that the lever 250 after it has opened the capsule, returns to a release position and releases the opening in the capsule to provide easier access for flushing water.

On an in 2 not shown way the recording 130 over the water pipe 290 with the laundry receiving chamber 110 connected. At the beginning of the washing process, the detergent or detergent component can be introduced into the chamber by a stream of water in which the detergent dissolves 110 be transported. Here, in the detergent capsule chambers 210a and 210b stored detergent ingredients are mixed.

After the detergent from the chambers 210a and 210b Is discharged, the detergent capsule can 180 from the water pipe 290 even rinsed separately, so cleaned, and then removed or via a disposal device 300 be disposed of. This disposal corresponds in the illustrated embodiment disposal, as it is known from conventional household press capsule machines. In this case, a blocking element 310 automatically or manually triggered along a release direction X are displaced, whereby one about a pivot axis 320 pivotable trapdoor 330 can yield, leaving the detergent capsule 180 into a disposal area 340 which, for example, but not shown, may be formed as drawer drawer by the user.

The decisive factor here is that of the sensor element 150 collected information about the detergent capsule 180 about the in 1 illustrated line elements 160 to the control unit 170 be transmitted.

The control unit 170 are also information regarding the in the laundry room 110 insertable textiles. This is the washing machine 100 evidenced 1 in the area of one of the receiving door 120 concealed opening of the receiving chamber 110 another sensor element 150 ' assigned. This sensor element may likewise be a scanner element in the manner of a barcode scanner. A corresponding barcode can in this case, in particular, as it is in 3 is shown on a textile product 350 be arranged in the illustrated embodiment, a Mr. T-shirt. This is an in 3 only schematically illustrated readable element 360 in the area of the collar 370 of the T-shirt 350 appropriate. The readable element 360 For example, it may be present as a barcode printed on a T-shirt label.

The user can do this in 3 illustrated T-shirt after opening the in 1 shown receiving door 120 for detection on the barcode scanner 150 ' pass by, this one being in the barcode 360 Automatically collect and store the data contained in the 1 shown control unit 170 can transfer. To control the data acquisition, the washing machine in positive detection, a signal, for example in the form of a sound signal or by lighting a the sensor element 150 ' assigned indicator light 380 , output.

Alternatively, however, it is also conceivable that the sensor element 150 ' Part of an RFID system, wherein the textiles have RFID chips. The detection system of the washing machine 100 In this case, information about the textiles can already be obtained when the textiles approach the washing machine. For example, in a private household, a laundry basket with laundry of a particular color, for example white laundry, may be present, wherein the laundry basket has an RFID chip which contains information about the color composition of the laundry collected in the laundry basket. When approaching the laundry basket to the machine 100 This can thus automatically select a corresponding white wash program via their control unit.

The laundry program to be selected thus does not need to be selected by the user himself. This only needs an on / off switch 390 (see. 1 ), which has exactly one adjustment. The user is thus not overwhelmed, as in conventional household washing machines by a variety of washing programs to be set. In particular, no separate program selector switch is necessary.

A second embodiment is in 4 shown. The household washing machine shown here 100 ' corresponds in large part to the washing machine according to 1 , An essential difference consists in a different embodiment of the detergent receiving area 130 ' , This has in the illustrated embodiments, not only a receptacle for a single detergent capsule, but three separate openings 140a . 140b and 140c , In these three openings 140a . 140b . 140c Assigned recordings each sensor means not shown a detection device are arranged, which via the conduit element 160 ' with the control unit 170 ' are connected.

During the first detergent opening 140a is formed star-shaped, is the second detergent opening 140b round and the third detergent opening 140c square shaped.

The detergent openings 140a . 140b . 140c thus allow only the inclusion of detergent capsules of certain forms. So can the opening 140a assigned recording record only in cross-section star-shaped detergent capsules.

The associated detergent capsules make it possible, via their shape, to make a statement regarding the detergent contained in them. For example, a detergent capsule of round cross-section may contain a colored laundry detergent. If the user wants to wash a wash load of colored laundry, he can put the laundry in the laundry room 110 ' Introduce the receiving door 120 Close and then a round in cross-section, a corresponding Buntwaschmittel having detergent capsule in the opening 140b introduce. One in the area of the opening 140b arranged sensor element, such as a light barrier, now detects the introduction of the capsule and passes the information to the control unit 170 ' Next, which then automatically selects the appropriate Buntwaschprogramm. The user only needs the power switch to start the wash program 390 ' to use. This can alternatively be operated before introducing the laundry or detergent capsule.

The principle of in 4 Form coding shown is alternatively transferable to a degree coding. For example, different detergent container openings of the same or different shape, but of different dimensions, may be provided on the washing machine. By choosing a corresponding rumble detergent capsule of the washing machine thus indirectly information about the amount of laundry to be washed can be transmitted.

Another embodiment shows 5 , evidenced 5 has a designed as a substantially conventional commercial washing machine 10 trained inventive device 80 a receiving chamber 11 which is typically formed by a rotating drum and can be closed door-like by a closure glass, not shown. A program selector 12 is indicated and used for manual adjustment of a particular program by the operator. Other program selectors, for example, the nature of the textiles to be cleaned, the type and degree of contamination may be on the washing machine 10 be provided, but are in 5 not shown.

The outline of the 5 shows that the washing machine 10 via a supply line 13 with different containers 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h connected is. From the central supply line 13 therefore go corresponding branches 17a . 17b . 17c . 17d . 17e . 17f . 17g . 17h to the appropriate containers.

Equally, an electronic control line 14 provided, which is also denominatable as a signal line and also with the individual containers 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h connected is. Again, go from the signal line 14 corresponding branches 18a . 18b . 18c . 18d . 18e . 18f . 18g . 18h from.

First, it should be noted that the architecture of both the supply line 13 as well as the signal line 14 purely schematic and only to be understood as an example. For example, it may alternatively be provided a star connection, which, starting from the washing machine 10 to every container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h a separate control line 14 and a separate supply line 13 runs. It can also be provided that the supply line 13 at the in 5 aborted shown end connected to a water pipe. This water pipe can also feed the washing machine to carry out a washing process. Alternatively, from any container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h a separate water supply takes place. The water flowing in the water pipes can also bring about a transport of the active ingredients, and entrain these agents, for example, in the water stream or, z. B. also dissolved in it, take along.

Finally, the control line can 14 , as shown, be equipped with branches. Alternatively, from the washing machine, or from an indicated central electronic controller or control unit 73 the washing machine, to every container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h or in each case to a dedicated metering separate control lines run.

The container 15a is, schematically in 5 shown, a metering device 16 , z. As a conventional metering pump assigned. The control line 14 connects the washing machine 10 , in particular the control unit 73 , over the junction 18a with the metering device 16 , In the container 15a is a first enzyme, for example, lipase E ₁ , arranged. By selecting a suitable washing program with the program selector switch 12 For example, it can be set to dissolve greasy soiling. The metering device 16 receives from the control unit 73 of the washing machine 10 therefore, at an optimized time during the wash program, instructing a certain amount of lipase E ₁ from the container 15a in the corresponding feeder branch 17a the supply line 13 contribute.

Corresponding metering devices 16 are also the other containers 15b . 15c . 15d . 15e . 15f . 15g . 15h assigned, for reasons of clarity but in 5 not shown.

In the container 15b there is an enzyme E ₂ , for example cellulase. Another enzyme E ₃ be found in the container 15c , for example, amylase. Finally, there is an enzyme E ₄ , z. B. protease, in the container 15d ,

Proteases primarily cleave proteins and act against soiling, such as spinach and the like. Amylases break starch and act against mashed potatoes, chocolate, pudding and the like. Lipases split fats and act against salad oil, dripping, sunscreen, make-up and the like. Cellulase removes cotton fluff and refreshes colored fabrics. By individual dosing of the different four enzymes E ₁ , E ₂ , E ₃ , E ₄ can thus be optimally adapted to the pollution production of a detergent, without bringing unnecessary agents into the detergent and pollute the waste water unduly, but at the same time the required Active ingredients can be used in sufficient quantities.

The containers 15e . 15f contain different surfactants T ₁ and T ₂ , or different surfactant mixtures. This is intended merely to illustrate, by way of example, that it is advantageously possible to also provide different containers for different surfactants. The number of containers or the number of different surfactants or surfactant mixtures depends on the extent to which individual dosability of the detergent active ingredients is desired.

The container 15g serves to accommodate a complexing agent K. Also, the complexing agent can be controlled by the washing machine 10 be metered depending on the choice of the washing program.

The container shown by way of example 15h serves to accommodate, for example, a solvent or a complexing agent or an anti-corrosive agent or a bleaching agent, od. Like. Also, in 5 not shown containers can be provided. It is also possible to mix individual active ingredients, for example surfactants, with complexing agents, etc. It is important that the active ingredients are present in concentrate form, without emulsifiers, preservatives and carriers, such as fillers or water, stabilizers, etc. mixed or mixed in excessive amounts.

At every container 15 is an RFID chip 70 arranged in which information about the active substance contained in the container is inscribed. At the container 15a is an RFID chip 70a arranged, and for example at his respect 5 glued left outside. In the RFID chip 70a is the information inscribed in the container 15a Lipase E ₁ is located. In the RFID chip 70b which is attached to the second container 15b is attached, the information is inscribed in that container 15b Cellulase is located.

Also in the rest, in 5 indicated RFID elements 70c . 70d . 70e . 70f . 70g . 70h is in each case the information inscribed, which active ingredient, ie the enzymes E ₃ , E ₄ , the surfactants T ₁ , T ₂ , the complexing agent K, etc. is located in the respective container.

At the washing machine 10 is a detection means indicated only by dashed lines 71 arranged. The detection device 71 is capable of the RFID chips 70a . 70b . 70c . 70d . 70e . 70f . 70g . 70h to read and to capture the information stored therein each. The readout is wireless and contactless. The registration unit 71 may be conventional and emit an electromagnetic signal, which is to excite the electrical circuit in the RFID chip 70a . 70b . 70c . 70d . 70e . 70f . 70g . 70h leads. The detection device 71 can then that due to the excitation of the corresponding circuit in the RFID chip 70a . 70b . 70c . 70d . 70e . 70f . 70g . 70h capture and detect and assign or process generated signal. This information can then be sent to the control unit 73 connected to the detection device 71 connected in a manner not shown, are transmitted.

In the event that the container 15a with the enzyme lipase E ₁ to the coupling site 72 can be brought, for example, due to the mechanical coupling a corresponding query by the detection device 71 be initiated automatically.

alternative A registration can also be regular, in specific time intervals. Finally, can An information collection regularly also only be made at the beginning of a wash program.

Is the container 15a with the RFID chip 70a in or at the designated coupling point 72 so is the RFID element 70a in a sufficient proximity to the detection device 71 arranged. A readout of the information can be at this small spatial proximity of the elements 70a and 71 done to each other. Of course, this also applies equally to the furthest from the detection device 71 remote RFID elements 70h and 70d , These are also from the registration unit 71 detectable.

The coupling point 72 For example, it may be a conventional receptacle for a receptacle having a plug-like end. Also other connectors, snap-in connections, contact connections or the like, a finally, bayonet-type or helical connections between the container 15a and the coupling point 72 come into question. It is crucial that after completion of the Ankoppelvorganges the respective metering device 16 from the interior of the container 15a dosed individually can take a certain amount of active ingredient if necessary.

Is the container 15 empty, this can be from the coupling point 72 be solved in a simple manner and replaced by a new container filled with active ingredient. This new container in turn carries an RFID element 70a So it's from the capture device 71 can be detected as soon as the corresponding new container to the coupling point 72 docked.

The of the detection device 71 captured information is sent to the control unit 73 forwarded, which processes this information. The control unit 73 For example, it may be noted that, if improperly used in place of the desired agent, e.g. As the enzyme E ₂ due to an exchange of the container 15b accidentally a container with another active substance, eg. B. with the enzyme E ₁ (lipase) is coupled. Such a confusion can occur when the two containers 15a and 15b have a same outer shape.

According to the invention by the coding of the two containers 15a . 15b with an RFID chip and with information about the active ingredients contained such a permutation are excluded.

The information about each in the container 15a contained active ingredient, for. B. E ₁ , can be encoded, for example, with the aid of an article number or the like, or directly, be inscribed as an enzyme name in the RFID element. When using codes, such as. B. article numbers, the control unit 73 or possibly even the detection device 71 associate these codes with the actual enzyme names or, at any rate, the codes or enzyme names or drug names required to perform the wash.

It should be noted that instead of an RFID element on the containers 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h fastened elements 70a . 70b . 70c . 70d . 70e . 70f . 70g . 70h of course also be provided by another electronic storage element or the other transponder or other suitable element which can carry information. For example, the container could 15a with an electronic memory, z. B. be equipped with an EEPROM memory, a Flashstick or the like, and have electronic or electrical plug contacts, with mating plug contacts in the coupling point 72 can be brought into electrical contact. Via a signal line, which is the coupling point 72 with the detection device 71 connects, then the respective information could be queried as signal data via this control line.

evidenced 6 has an alternatively constructed container 15a four chambers 19a . 19b . 19c . 19d on. Here, the enzymes E ₁ , E ₂ , E ₃ , E ₄ are arranged in the individual chambers, which should be illustrated by different levels of filling. The dosing device also shown 16 is able to access the individual chambers 19a . 19b . 19c . 19d to act separately and to dose the individual enzymes E ₁ , E ₂ , E ₃ , E ₄ individually. The container 15a thus has four separate containers here.

The container 15 with its four chambers 19a . 19b . 19c . 19d can be as a unit of four part containers 19a . 19b . 19c . 19d be considered. Each subcontainer has its own RFID chip here 70a . 70b . 70c . 70d as already associated with the embodiment of 5 has been explained.

Alternatively, it is also possible to the container 15a to assign a common RFID chip containing information about all the active ingredients in the four chambers 19a . 19b . 19c . 19d are housed.

In the embodiment of the 6 is indicated that the detection device 71 also the metering device 16 can be assigned. Thus, the detection device 71 capture the information and, if necessary, directly to control the metering device 16 use. Alternatively, the information from the detector 71 but also over the lines 18a respectively 14 to the control unit 73 or via separate lines, not shown, or wireless, optical or electromagnetic to the control unit 73 be transmitted. On the location of the detection device 71 it does not matter in that respect. The example of 6 illustrates, however, that an arrangement of the detection device 71 in the immediate vicinity of the elements 70a . 70b . 70c . 70d to read the information may be advantageous.

For the purposes of the present patent application, the term "active ingredient" includes enzymes and surfactants, but also mixtures thereof and complete detergents. The term active ingredient mixture also includes any mixtures of active ingredients with additives such as solvents, complexing agents, bleaching agents, anti-corrosives, fillers, stabilizers and water. It should be noted that certain active ingredients or drug mixtures achieve their optimum cleaning soil-dissolving or functional effect advantageously in a particular alkaline or acidic environment.

The Washing machine and cleaning device according to the invention can ensure that individual drugs or drug mixtures during a washing program successively in the receiving chamber be supplied. In this case, the active ingredients within a wash program at different times and at different pH values of the in the receiving chamber located Wash water or wash solution act.

Different In terms of the pH of the washing or cleaning fluid during a wash program change. The change The pH value can be directly from the active ingredients or from Drug mixtures are caused or alternatively by separate Additives which are attached to the active substances or mixtures of active substances or which are supplied separately.

So For example, you can make sure that at the beginning a washing program, a first active ingredient in the receiving chamber and because of its chemical properties there for an alkaline environment, or containing additives, which provide an alkaline environment. The additives If necessary, they can also be obtained from a separate container be supplied.

below, advantageously only after expiration of a period of time during the active substance has its optimal effect another active substance can be introduced into the receiving chamber, wherein at the same time the pH in a predetermined manner in the acidic environment replaced.

following can z. B. a third active ingredient or the aforementioned first drug to be added and turn for a change of the washing water milieu towards the alkaline.

On This can be the textiles or objects to be cleaned or the active ingredients during a wash program different pH values be exposed, thereby ensuring optimal effect of each active ingredient can be achieved.

The In particular, as described herein, action on the pH has Combination with the possibility of cold washing, as above also described the positive effect that overall a calcification is avoided. Therefore, by the described measures especially the use of complexing agents completely avoided or at least minimized.
