Description

Washing machine, Reiniqunqseinrichtung, methods for washing and dishwasher, u. a.

The invention first relates to a washing machine according to the

Preamble of claim 1.

In particular, the invention relates to a washing machine for use in the commercial sector. Such commercial washing machines are manufactured for some time and are used in particular for the cleaning of work clothes, such as work coats and trousers, which are exposed to heavy soiling, such as workwear in the slaughterhouse or butcher, bakery, firefighters etc.

There are a number of detergents known that contain particular active ingredients in adaptation to special requirements when washing the soiled textiles. In particular, it is known, depending on the application, to provide special enzymes, special surfactants, special bleaching agents, special odorants, special solvents, etc.

Even with commercial washing machines, however, it is not foreseeable in advance what kind of soiling the textiles to be cleaned, adjustments are required both in terms of degree of contamination, as well as with respect to the nature of the pollution and the nature of the textiles to be cleaned.

The object of the invention is a presupposed as known washing machine according to the preamble of the claim 1 in such a way that with high efficiency, the environmental impact is reduced.

The invention solves this problem with the features of claim 1, in particular with those of the characterizing part, and is accordingly characterized in that the receiving chamber in a switchable, communicative connection with a plurality of

Containers stands, wherein in the containers different active ingredients for mixing a detergent are arranged, and wherein by selecting a program on the program selector dosing devices are responsive, which are assigned to the different containers and / or the different agents to a to the type or

Composition of the objects and / or adapted to the type of pollution detergent composed of the active ingredients and forward the receiving chamber.

The principle of the invention is thus essentially to arrange a plurality of containers in spatial allocation to the washing machine. In the containers different active ingredients are arranged, which can be combined to form a detergent.

As possible, suitable active ingredients, for example, different enzymes and / or different surfactants are provided. Also, different enzyme mixtures or different surfactant mixtures in question.

Likewise suitable as active ingredients complexing agents, bleaching agents, preservatives, solvents, odors, corrosive agents, etc. in question. Almost all components of conventional detergents can be arranged in separate containers and metered individually by appropriate metering devices. By selecting a washing program on a program selector switch on the washing machine, the user can take into account which textiles or textiles to be cleaned are concerned and what type or degree of soiling they are. The program selector switch or a controller operatively connected thereto can then respond to the corresponding metering devices which are connected to the washing machine, for example via signal control lines. The metering devices can meter the individual active substances in accordance with a stored table in accordance with the selected washing program and feed them via a common supply line or via separate supply lines of the washing machine, in particular a receiving chamber for the objects to be cleaned. The containers are in communicative communication with the receiving chamber, that is to say that it is a tube, a hose, a screw conveyor or the like, which connects the containers together or separately to the receiving chamber and supplies the active ingredients to the container Recording chamber allows. The connection is switchable, that is via the metering device or additional separate valves or switching arrangements, the supply of the active ingredient can be initiated or prevented.

Because the individual active ingredients are sorted as a concentrate, separated and arranged separately in containers and can be metered individually, a detergent optimized with regard to the desired application can be put together. While conventional detergents try to provide a particularly wide range of applications, and for a particularly extensive mixture contain different active ingredients that cover virtually any purpose, that is, any possible degree of contamination, any type of contamination and any possible nature of the objects to be cleaned, according to the invention a variable composition of the detergent on site, done in or on the washing machine.

On the other hand, the fact that concentrates are used in active ingredients, the transport and packaging costs are significantly reduced. For example, conventional liquid detergents use water contents of more than 80%. In the washing machine according to the invention, a mixing of the active ingredients of the detergent with water can only take place during or after the supply of the active ingredients in the receiving chamber. The water is available on site, since the washing machine is already connected to a water pipe.

The fact that the high water content, which is common in liquid detergents omitted, the transport or packaging costs can be reduced by up to 70 to 80%.

A mixture of the active ingredients together to provide a detergent can be done either in the feed line or in the receiving chamber or in a mixing chamber upstream of the receiving chamber on the washing machine or on the supply line. As a receiving chamber in the sense of the present patent application is understood in the case of a washing machine, in particular a commercial washing machine or a household washing machine, a rotating drum. In the case of a cleaning device is understood as a receptacle each tub, the detergent or Spülmitte! to carry out the washing process of the objects to be cleaned.

The fact that, depending on the choice of the wash program, a special composition of the Waschmitteis, the wastewater pollution can be kept low. Since in each case only the active ingredients are used, which considers the washing program after selection by the user to be essential, the waters are not burdened with expendable detergent ingredients.

The mixture of the individual active ingredients for the production of a detergent on site, ie in the washing machine or at least near the washing machine, is also advantageous, bearing in mind that it is not possible to mix any active ingredients with conventional detergents. Thus, it has been recognized by the Applicant that certain active ingredients can settle, for example, in liquid detergents, so that they are not homogeneously distributed in the finished conventionally produced detergent. It has also been observed by the Applicant that certain drugs can chemically react with each other when mixed together in a conventional detergent.

Due to the separate and separate storage of the individual active ingredients in individual containers according to the present invention and by the single-dose mixing together of the active ingredients only in or at least close to the washing machine, during washing or just before washing, such settling problems and unwanted chemical reactions be avoided between the individual active ingredients. The active ingredients are used directly there, namely in the receiving chamber, without the occurrence of a chemical reaction which is detrimental to their effectiveness. The applicant is aware of a washing machine of the prior art, in which the washing machine with different containers is in communicable communication, wherein in the containers different detergents are arranged. The washing machine according to the invention differs therefrom in that detergent active ingredients, that is to say components of a detergent, can be mixed together to form a detergent. As detergent active ingredients in particular enzymes, surfactants, complexing agents, etc. are considered.

It is particularly advantageous that several active ingredients of the receiving chamber can be fed simultaneously, since in this way a particularly homogeneous mixing of the active ingredients is possible.

Alternatively, it is advantageous that the active substances of the receiving chamber can be fed in succession. This can allow a time-delayed and optimized for the wash program addition of the individual active ingredients. Different washing steps during a washing program can also be carried out, for example, at different temperatures. According to the invention, certain active ingredients, e.g. certain enzymes or enzyme mixtures, are supplied at certain temperatures and thus optimized. Due to the individual metering of the individual active ingredients, a further optimization of the washing efficiency can take place.

Advantageously, the active ingredients are arranged as concentrates in the containers. As a concentrate is in particular a

Drug composition or the nature of a drug combination referred to, in the water or the

Filler shares are kept low or almost completely avoided become. Conventional liquid detergents have water contents of up to 80% in some cases. Conventional powder detergents have very high percentages of fillers, which are not active ingredients of a detergent, but only affect the consistency of the detergent. On these additives, which are present only as carriers to provide a conventional detergent, can be dispensed almost completely according to the invention.

According to an advantageous embodiment of the invention in a first container, a first enzyme as an active ingredient and in a second

Container a second, different enzyme arranged as an active ingredient

Splitting the detergent components into different enzymes and the ability to dispense these enzymes one at a time allows for optimized washing efficiency. For example, lipases can be used to break down fats and, for example, to optimally clean professional clothing such as that obtained in a slaughterhouse. Amylases should not be needed when cleaning greasy clothing, at least in some applications.

By choosing an appropriate washing program, e.g. entitled "Purification of greasy soiled professional gowns", it would then be possible to control that the enzyme amylase has been omitted or has only been metered low and that the enzyme lipase has been added in high doses to the detergent.

Alternatively, for example, when cleaning bakery

Clothes, where it is expected that very strong contamination of the textiles with flour, that is to say with starch, can be found, high-dose addition of amylase as an enzyme, while lipases are practically not needed. While currently in conventional detergents, for example, four different enzymes, namely proteases, amylases, lipases and cellulases, are used, it is expected that in the future even more separate enzymes can be used for further optimization. According to the number of reasonably separable enzymes, a corresponding number of containers should be provided for the different enzymes.

Under certain circumstances, a common container for a first enzyme mixture and another separate container for another, second enzyme mixture comes into consideration.

Likewise, advantageously, a first container for a first type of surfactant and a further container for a second type of surfactant may be provided. By providing different, individually metered surfactants, an adaptation to different contaminants can also be optimized. It is also possible, for example, for allergy sufferers without enzymes or without certain surfactants to carry out the washing programs.

The invention solves the above-described object also with the features of claim 15.

It is essential to the invention that the active substances or, if appropriate, the mixtures of active substances are fed successively to the receiving chamber within a washing program or within a washing process. Different active substances may themselves have different pH values, especially if they are already present in liquid form. Alternatively, the active ingredients in the washing liquid in the receiving chamber can develop different pH values. You can make sure that in the receiving chamber Washing liquid located at a certain time and for a certain duration of a certain pH value, which changes in the course of the wash program. Taking into account a particularly suitable pH, the active ingredients or, where appropriate, the additives can develop a particularly advantageous action and particularly efficiently clean or treat the objects to be washed.

In particular, during a wash program, first a first pH value a, subsequently a different pH value b and finally, if appropriate, a third pH value c, can be achieved during the program. Thus, the mode of action of the active ingredients can be significantly improved. It is also possible in accordance with the invention to use active ingredients which conventionally could not be used since the prior art only washed alkaline. For example, according to the invention, a washing program may begin first in an acidic environment, then in an alkaline d. H. basic environment can be continued with the same or with other active ingredients and finally terminated at the end in an acidic environment again.

For example, wool materials easily acidified after completion of washing process can be removed from the receiving chamber, so that an impregnation or a flame retardant coating or the like can be applied in a particularly simple manner, for example, because the adhesion has been improved. Other advantageously designed washes with a single or multiple change in pH are possible.

The advantages described in connection with the subject-matter of claim 15 apply equally or analogously to application in connection with the objects of claims 28, 35, 41 and 42. The invention relates to the Wetteren a cleaning device according to the preamble of claim 16th

Object of this invention is to further develop according to the preamble of claim 16 assumed cleaning device to the effect that the burden of wastewater is reduced.

The invention solves this problem with the features of claim 16, in particular with those of the characterizing part, and is accordingly characterized in that the receiving basin in a switchable, communicative connection with a plurality of

Containers stands, wherein in the containers different active ingredients of a cleaning agent are arranged individually, which are individually metered to mix a detergent composed of the active ingredients.

Analogous to the above-mentioned appreciation of the invention according to claim 1, the same advantages come into play here. By individually mixing a detergent of different active ingredients optimal adjustments can be made to the objects to be cleaned. This makes it possible to use only those active ingredients that are actually required for the respective application case. Unnecessary active substances are simply omitted, which reduces the pollution of the wastewater.

The invention further relates to a washing machine according to the preamble of claim 20. This is a household washing machine, that is to say a washing machine of essentially known dimensions, as can be found in virtually every household.

The invention has the object of providing a washing machine, which is assumed to be known according to the preamble of claim 20, to further develop that a more variable replaceability at high comfort is possible.

The invention solves this problem with the features of

Claim 20, in particular with those of the characterizing part, and is accordingly characterized in that the receiving chamber is in switchable, communicatively connected to a plurality of containers, wherein in the containers different active ingredients for mixing a detergent are arranged, and wherein by selecting a program on the program selector dosing devices are responsive, which are assigned to the different containers and / or the different active ingredients to assemble a matched to the nature or nature of the objects and / or the type of pollution detergent from the active ingredients and forward the receiving chamber.

The principle of the invention thus consists essentially, analogous to the invention described above in claim 1, also to provide a plurality of containers with different active substances in a domestic appliance. As active ingredients in a household washing machine essentially the same, explained above to claim 1 active ingredients in question. It should be noted that the design effort in a Haushaltswaschmaschϊne must be kept lower due to the price requirements than a commercial intended for washing machine. In question Therefore, for example, only three containers, one container for receiving bleach, another container for receiving enzymes or an enzyme mixture and a third container for receiving a surfactant or a surfactant used. The surfactant mixture may at the same time also contain other active ingredients as constituents of a detergent, such as corrosive agents, complexing agents and softeners.

For example, if an allergic person's laundry is to be laundered, a wash program may ensure that enzymes which could not trigger enzymes are added to the detergent.

In the event that cooking linen is washed, bleaching agent may be added accordingly. In the event that washed coloreds, it can be ensured that no bleach is added. The user of the washing machine therefore does not have to use different detergents for color and cooking laundry, but leaves the choice of detergent ingredients of the washing machine.

The invention further relates to a washing machine according to the preamble of claim 29.

The object of the invention is to further develop a known as presupposed washing machine according to the preamble of claim 29 that a more variable substitution with high comfort is possible.

The invention solves this problem with the features of

Claim 29, in particular with those of the characterizing part, and is Accordingly, characterized in that a plurality of containers is provided, in which different active ingredients for mixing a detergent can be arranged, wherein by selecting a program on the program selector dosing devices are addressed, which are assigned to the different containers and / or the different agents to a to assemble from the active ingredients adapted to the nature or nature of the objects and / or the type of contamination detergent and supply the receiving chamber, wherein the containers are mounted directly on the washing machine.

According to the basic principle of this invention, a plurality of containers for holding different active ingredients for mixing a detergent are mounted directly on the washing machine. While for conventional detergents e.g. Receiving drawers are provided, in which, for example, a liquid detergent can be given, in the washing machine according to the invention, a plurality of containers arranged directly on the washing machine, wherein the containers in particular the separate housing and recording of

a) bleaching agents,

b) Enzyme mixtures and

c) surfactant mixtures,

optionally with other active ingredients serve.

The containers are preferably releasably fastened in the washing machine. You can in particular the manner of a cartridge be formed, and also individually, or together as a structural unit, releasably be fastened in the washing machine. The containers can be filled individually. Thus, the user can refill bleach at regular intervals, refill enzyme mixture or top up surfactant mixture. Each container has a volume that allows the inclusion of an amount of the corresponding active ingredient, which is sufficient for a variety of washes. It is particularly advantageous if the individual containers are designed in the manner of cartridges, as known from color ink-jet printer cartridges.

The invention further relates to a method for washing articles, such as textiles, industrial products od. Dgi., According to claim 36.

This invention has for its object to improve a method for washing articles, as practiced with a conventional washing machine to improve.

The invention solves this problem with the features of

Claim 36, in particular with those of the characterizing part, and is accordingly characterized in that to adapt to the type of contamination of the objects to be cleaned and / or in adaptation to the nature or nature of the objects, a suitable washing program is selected, and that in or at the washing machine according to the selected washing program a detergent from individual, located in different containers concentrates of active ingredients is mixed together by individual dosage of the active ingredients. With regard to the method, the advantages mentioned above for a washing machine apply analogously, so that reference can be made to this.

The invention further relates to a dishwasher according to the preamble of claim 43.

Such a dishwasher is the kind of a usual

Household appliance as known provided. In the known dishwasher, a first container for a cleaning tab, another

Container for rinse aid and a third container for salt provided.

Each rinse requires a new detergent tab.

Starting from a known dishwasher, the object of the invention is to further develop the dishwasher so that a higher efficiency is possible.

The invention solves this problem with the Merkmaien of claim 43, in particular with those of the characterizing part, and is accordingly characterized in that a container for a liquid detergent is provided which has a volume for receiving a detergent dose for a plurality of rinses , And that a metering device is provided, which makes a dosage of Reinigungsmitteis according to a selected wash program.

The principle of the invention is a container for liquid

Provide cleaning agent, which is a large amount of

Detergent can absorb. A dosing device allows for individual dosing, according to the selected program and at the desired time. For example, during a Rinsing program several times, eg at an optimal temperature, rinsing center! to be added. The container can be detachably attached to the dishwasher and in particular be designed as a cartridge. Thus, if necessary, the corresponding container can be refilled or replaced and replaced with a new container.

It is therefore no longer necessary to insert a separate detergent tab for each rinse, so that the comfort can be increased. A sufficiently large sized container, for example, for 30 or 50 rinses, increases the extent of the comfort in the operation of the dishwasher. By arranging a liquid detergent, a particularly fine dosage can be made, for example, if only slightly dirty dishes to be cleaned. This also reduces the wastewater load and increases the efficiency of the dishwasher. In each case only as much cleaning agent is added as required.

The invention further relates to a dishwasher according to claim 47.

The object of this invention is to provide a dishwasher which can be used variably.

The invention solves this problem with the features of

Claim 47, in particular with those of the characterizing part, and is accordingly characterized in that a plurality of containers for different active ingredients of a cleaning agent, such as enzymes, surfactants, od. Like. Are provided, wherein metering devices are provided with which the active ingredients according to a selected washing program individually can be dosed. The principle of the invention consists essentially in that analogous to the arrangement described above for a washing machine a plurality of containers with different active ingredients of a cleaning agent is provided. In the containers, active ingredients as constituents of a rinsing agent, such as enzymes, surfactants, od. Dg! .., Arranged, which can be dosed and mixed together as needed on the spot, controlled by a corresponding wash program, in order to optimally adapted rinsing - or detergent to represent. In the event that, for example, allergy sufferers can not tolerate certain active ingredients of a cleaning agent, such components can be omitted by an intelligent control.

The invention further relates to a cleaning device according to claim 48.

Cleaning devices on the type of car washes are well known. Car washes for passenger cars or for commercial vehicles are known, for example, in the form of stationary or mobile equipment in which the vehicle is either actively passed through an appropriate cleaning device or pulled through it. In mobile vehicle washes, portals or similar devices may also be moved relative to the stationary vehicle.

A conventional car wash has as a device for

Applying a detergent-containing liquid on the

Vehicle outer surface numerous nozzles or the like spray heads with which the cleaning liquid or washing liquid on the Vehicle outer surface is applied. For this purpose, conventional cleaning agents are used in the prior art.

The invention has for its object to form a known cleaning environmentally friendly.

The invention solves this problem with the features of claim 48.

In the inventive way, for example, consists of

Possibility to design a detergent composition variable depending on the type of contamination of the vehicle and so individually dosed and efficiently bring the active ingredients used. Thus, the environmental impact can be reduced. Also, the active ingredients in their composition can be mixed as desired or individually metered successively applied at different times via the nozzles on the vehicle surface.

Preferably, the active ingredients are housed as a concentrate individually in different containers. In this case, the active ingredients are diluted with water before they are sprayed onto the vehicle surface via the nozzles or similar devices.

More significant advantages of the invention will become apparent from the non-cited subclaims and with reference to the following description of several illustrated in the drawings Ausführungsbeispϊele. In it show, all in a schematic, simplified representation:

Fig. 8 in a schematic interior view according to arrow VIII in Fig. 7, the dishwasher of FIG. 7, and

FIG. 9 is a schematic view analogous to FIG. 6 of a further embodiment of a cleaning device according to the invention designed as a washing line

The same or comparable parts or elements are in the following description of the figures, even as far as different embodiments are concerned, partially denoted by the same reference numerals.

As shown in FIG. 1, a commercial washing machine 10 of essentially conventional design has a receiving chamber 11 which is typically formed by a rotating drum and is door-lockable by a closure glass, not shown. A Programmwahischalter 12 is indicated and used for manual adjustment of a particular program by the operator. Other program selection devices, for example, the nature of the textiles to be cleaned, the nature and the degree of contamination may be provided on the washing machine 10, but are not shown in Fig. 1.

The schematic diagram of FIG. 1 shows that the washing machine 10 is connected via a feed line 13 to different containers 15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h. From the central supply line 13, therefore, corresponding branches 17a, 17b, 17c, 17d, 17e, 17f, 17g, 17h go to the corresponding containers.

Similarly, an electronic control line 14 is provided, which can also be designated as a signal line and which is also connected to the individual containers 15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h. Here, too, branches 14a, 18b, 18c, 18d, 18e, 18f, 18g, 18h depart from the signal line 14.

First, it should be noted that the architecture of both the lead 13 and the signal line 14 is to be understood purely schematically. For example, a star connection may alternatively be provided, according to which starting from the washing machine 10 to each 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 is connected to the end shown broken off in Fig. 1 with a water line. This water pipe can also feed the washing machine to carry out a washing process. Alternatively, of each container 15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h ago a separate water feed done. The water flowing in the water pipes can also bring about a transport of the active ingredients, and entrain these active ingredients, for example, in the water flow or, dissolved therein, take along.

Finally, the control line 14, as shown, with

Be equipped branches. Alternatively, from the washing machine, or from a not shown central electronic control of the washing machine, to each container 15a, 15b, 15c, 15d, 15e, 15f, 15g,

15h separate control lines run.

The container 15a is shown schematically in Fig. 1, a Dosϊereinrichtung 16, e.g. a conventional metering pump, assigned. The control line 14 connects the washing machine 10 via the branch 18a with the metering device 16. In the container 15a is a first enzyme, for example, lipase E ^ arranged. By selecting a corresponding washing program with the program selector switch 12 can be set, for example, that greasy soiling should be solved. The metering device 16 receives from the control device, not shown, the washing machine 10 therefore at an optimized time during the wash program, the instruction to introduce a certain amount of lipase egg from the container 15a in the corresponding feed branch 17a of the supply line 13.

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

In the container 15b is an enzyme E ₂ , for example

Cellulase. Another enzyme E ₃ is in container 15c, for example, amylase. Finally, there is an enzyme E ₄ , eg protease, in the container 15 d.

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 fumes and refreshes colored textiles. By individually dosing the different four enzymes Ei, E2, E3, E ₄ can thus be optimally adapted to the pollution production of a detergent without causing unnecessary active ingredients get into the detergent and contaminate the waste water unduly, but at the same time the required active ingredients in the sufficient amount can be used.

The containers 15e, 15f contain different surfactants Ti 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 an eznzel dosability of the detergent active ingredients is desired.

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

The container 15h exemplified serves for receiving, for example, a solvent or a complexing agent or an anti-corrosive agent or a bleaching agent, or the like. Other containers, not shown in FIG. 1, can also 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.

As shown in FIG. 2, an alternatively constructed container 15a has four chambers 19a, 19b, 19c, 19d. Here, the enzymes Eu E ₂ , E ₃ , E ₄ are arranged in the individual chambers, which should be illustrated by different levels of filling. The dosing device 16 also shown is now able to act separately on the individual chambers 19a, 19b, 19c, 19d and to dose the individual enzymes Ei, E ₂ , E ₃ , E4 individually. The container 15a here thus has four separate containers in the sense of the patent application.

As active ingredients in the context of the present patent application, enzymes and surfactants are referred to inter alia, but also mixtures thereof. The term active ingredient mixture also includes any mixtures of active ingredients with additives such as, for example, solvents, complexing agents, bleaching agents, anti-corrosive agents, 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.

With the washing machine according to the invention and

Cleaning device can be made sure that individual

Active ingredients or drug mixtures are fed during a wash program successively in the receiving chamber. The active ingredients within a wash program can be different Times and at different pH values of the present in the receiving chamber wash water or the washing solution act.

In other words, the pH of the wash liquid may change during a wash program. The change in the pH can be caused directly by the active substances or by mixtures of active ingredients or alternatively by separate additives which are added to the active ingredients or active substance mixtures, or which are supplied separately.

Thus, for example, it can be ensured that at the beginning of a wash program, a first active ingredient is passed into the receiving chamber and because of its chemical properties there provides for an alkaline environment, or contains the additives that provide an alkaline environment. If appropriate, the additives can also be supplied from a separate container.

Subsequently, advantageously only after a period of time during which the active substance has exhibited its optimum effect, another active substance can be introduced into the receiving chamber, wherein at the same time the pH value changes in a predetermined manner into the acidic environment.

Subsequently, z. B. a third active ingredient or the aforementioned first active ingredient are added and in turn provide for a change of the wash water milieu into the alkaline.

In this way, the textiles or articles to be cleaned or the active ingredients during a wash program be exposed to different pH values, whereby an optimal effect of the individual active ingredients can be achieved.

Fig. 3 shows a household washing machine 20 according to the invention, which is connected in an analogous manner to the embodiment of FIGS. 1 and 2 via a supply line 21 and a signal line or control line 22 with individual containers 23a, 23b, 23c, 23d _r 23e.

According to the invention, the household washing machine has at least three different containers 23a, 23b and 23c. In the first container 23a is a concentrate of a bleaching agent B, in the second container 23b is an enzyme mixture E and in the third container 23c is a surfactant mixture T, which also also complexing, anti-corrosive! and water softener.

Optionally, further containers 23d and 23e as well as further containers (not shown) may also be provided, which allow an even finer individual variable composition of a detergent for operating the household washing machine 20.

As shown in FIG. 4, a washing machine 30 according to the invention has an insert 31 or a structural unit 31 which, as shown in FIG. 5, consists of three different containers 32a, 32b and 32c. The insert 31 can be detachably attached to the washing machine 30 as a unit as a cartridge.
