Description

Bleach-containing cleaning agent

The present application describes bleach-containing detergents.

The make-up and supply forms of detergents and cleaners are subject to continuously changing requirements. For some time now, the main focus has been on the convenient dosing of detergents and cleaners by the consumer and the simplification of the work steps necessary to carry out a washing or cleaning process.

In this context, in particular dosing systems for the multiple dosing of detergents and cleaners have recently come into the field of vision of the product developers. In these devices, it is possible to distinguish between dosing systems integrated in the dishwasher or textile washing machine on the one hand and independent and mobile dosing systems independent of the dishwasher or textile washing machine on the other hand. By means of these metering systems, which contain the multiple of the amount of detergent necessary for carrying out a single cleaning process, detergent or cleaning agent portions are metered into the interior of the cleaning machine by means of a metering device from a cartridge in an automatic or semi-automatic manner in the course of several successive cleaning processes. For the consumer eliminates the need for repeated manual dosing of detergents and cleaners. Examples of such devices are described in European patent application EP 1 759 624 A2 (Reckitt Benckiser) or in German patent application DE 10 2005 062 479 A1 (BSH Bosch and Siemens Hausgeräte GmbH).

Irrespective of the exact type of dosing systems used in the interior of dishwashers or textile washing machines, the detergents or cleaning agents contained in these multidose dosing devices are exposed to varying temperatures over a relatively long period of time, these temperatures being approximately the same as for carrying out the washing or cleaning processes same water temperatures used. These temperatures can be up to 95 ⁰ C, wherein in the range of machine dishwashing usually only temperatures between 50 and 75 ⁰ C are reached. Accordingly, a washing or cleaning agent contained in a dosing system provided for multiple dosing is repeatedly heated to temperatures well above the temperatures customary for transport and storage in the course of several washing or cleaning processes, temperature-sensitive active substances in particular being able to be affected. The group of these temperature-sensitive washing and cleaning-active substances include, among others, the bleaching agents.

The use of bleaching agents to increase the washing and cleaning performance of detergents and cleaning agents has been established in the prior art for decades, being in the field of Machine textile and dishwashing in particular oxygen bleach with perborates and percarbonates find application.

The decisive for the end user cleaning effect of bleach used in detergents and cleaners is determined except by the bleach itself to a considerable extent by the nature of the preparation of these bleaches and their stabilization against environmental influences.

Bleaching agents are offered both in solid and in liquid, for example dispersed, form.

The object of the present application was to provide a chemically and physically stable bleach dispersion, wherein in particular a stabilization of the bleach dispersion against phase separation / loss of activity at multiple temperature fluctuations (10 to 75 ⁰ C) should be achieved. Corresponding bleach preparations should be storable in a storage device located in the interior of a dishwasher or textile washing machine without significant loss of activity and be usable over a plurality of rinse cycles.

It has been found that low-water or anhydrous bleach preparations can be stabilized in a matrix of organic solvents and suspending agents. A first subject of the present application is therefore a cleaning agent with a water content below 5 wt .-%, comprising a) 10 to 45 wt .-% oxygen bleaching agent b) 10 to 89.5 wt .-% organic solvent c) 0.5 to 5% by weight of suspending agent

The water content of cleaning agents according to the invention is preferably less than 4% by weight, preferably less than 2% by weight and in particular less than 0.5% by weight. Particularly preferred cleaning agents according to the invention are anhydrous.

Bleaching agent preparations according to the invention contain as the first essential constituent one or more oxygen bleaching agents a). Among the compounds which serve as bleaches and deliver H ₂ O ₂ in water, sodium percarbonate, sodium perborate tetrahydrate and sodium perborate monohydrate are particularly important. Other useful bleaching agents are, for example, peroxy pyrophosphates, citrate perhydrates and peracid salts or peracids which yield H ₂ O ₂ , such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid. Furthermore, bleaching agents from the group of organic bleaching agents can also be used. Typical organic bleaches are the diacyl peroxides such as dibenzoyl peroxide. Other typical Organic bleaches are the peroxyacids, examples of which include the alkyl peroxyacids and the aryl peroxyacids.

Preferred bleach preparations are characterized in that the oxygen bleach a) is sodium percarbonate.

The weight fraction of bleach a), based on the total weight of the bleach preparation, in preferred embodiments is between 15 and 40% by weight, preferably between 18 and 35% by weight and in particular between 21 and 30% by weight.

The cleaning agents according to the invention, hereinafter also referred to as bleach preparations, are in dispersed form. For the desired physical stability of the bleach preparation, it has proven to be advantageous to control the particle size of the solid oxygen bleach present in the dispersion and to limit it to particle sizes below 1, 0 mm.

Particularly preferred bleach formulations of the invention are characterized in that the particle size of the bleach is less than 100 microns, preferably less than 50 microns and more preferably less than 20 microns, with particle sizes between 0.1 and 100 .mu.m, preferably 0.1 and 80 .mu.m and in particular 0.1 and 50 microns are preferred.

Some exemplary and advantageous in their chemical and physical stability bleach preparations are listed in Table 1 below:

As a second essential ingredient, bleach compositions according to the invention contain one or more organic solvents b).

Preferred organic solvents are selected from the group of monohydric or polyhydric alcohols, alkanolamines or glycol ethers. The solvents are preferably selected from ethanol, n- or i-propanol, butanol, glycol, propane- or butanediol, glycerol, diglycol, propyl- or butyldiglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, etheylene glycol mono-n-butyl ether, diethylene glycol methyl ether , Di-ethylene glycol ethyl ether, propylene glycol methyl, ethyl or propyl ether, dipropylene glycol methyl or ethyl ether, methoxy, ethoxy or butoxy triglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether and mixtures of these solvents.

Be particularly advantageous for the chemical and physical stability of the bleaching compositions when stored at temperatures above 2O ⁰ C, the 1, 3 propandiol has been found. Detergents according to the invention, which contain propanediol as organic solvent 1, 3, are particularly preferred for this reason.

The proportion by weight of the organic solvent used in the bleach compositions according to the invention is, based on the total weight of the cleaning agent, preferably b) between 30 and 86% by weight, preferably between 50 and 82% by weight and in particular between 70 and 80% by weight. ,

Some exemplary and advantageous in their chemical and physical stability bleach preparations are listed in Table 2 below:

As a third essential ingredient, the bleaching compositions of the invention contain suspending agents. The suspended agent used not only enables the adjustment of the viscosity of bleach preparations according to the invention but surprisingly additionally contributes to the chemical stability of the preparations, wherein an increase in the bleach stability was observed, in particular at suspension levels of 1, 1 wt .-% and above.

The weight content of the suspending agent c) in the total weight of the cleaning agent is preferably between 1, 1 and 4 wt .-%, preferably between 1, 1 and 3 wt .-% and in particular between 1, 1 and 2.5 wt .-%.

Some exemplary bleach preparations which are advantageous in terms of their chemical and physical stability are listed in Table 3 below:

Particularly suitable as suspending agents c) are phyllosilicates (for example montmorillonites), castor oil derivatives, soya lecithin, ethylcellulose, low molecular weight polyamides, silicic acid (for example hydrophobicized and / or amorphous silica), polyacrylates, polyvinylpyrrolidone, cellulose derivatives, polyureas, polyurethanes and polysaccharides.

Preferred cleaning agents are characterized in that the suspending agent c) is a saccharide suspending agent or a silicic acid suspending agent or a mixture of a saccharidic suspending agent with a suspending agent of silicic acid. Particularly preferred cleaning agents comprise a) from 15 to 40% by weight of sodium percarbonate b) from 50 to 82% by weight of 1,3-propanediol c) from 1.1 to 5% by weight of suspending agent from the group of saccharidic suspending agents and silicic acid Suspending agent, where

Cleaning agent comprising a) 15 to 40 wt .-% sodium percarbonate b) 50 to 82 wt .-% 1, 3-propanediol c) 1, 1 to 5 wt .-% hydroxyethyl cellulose

respectively.

Cleaning agent comprising a) 15 to 40 wt .-% sodium percarbonate b) 50 to 82 wt .-% 1, 3-propanediol c) 1, 1 to 5 wt .-% hydroxyethyl cellulose and silica

are very particularly preferred.

Some other exemplary bleaching agent formulations which are advantageous in terms of their chemical and physical stability are listed in Tables 4, 5 and 6 below:

Despite their high physical and chemical stability, the detergents according to the invention are distinguished by a low formulation complexity. This low level of complexity simplifies the preparation of the detergents and thus reduces the costs involved in providing these detergents. For this reason, preferred cleaning agents according to the invention are characterized in that, in addition to the essential constituents a), b) and c), they have at most three, preferably the highest two, more preferably at most one and in particular no further constituents. The proportion by weight of further constituents is preferably less than 10% by weight, preferably less than 5% by weight, more preferably less than 2% by weight and most preferably less than 0.1% by weight. Very particularly preferred cleaning agents according to the invention consist of the constituents listed in Tables 1 to 6. The cleaning agents according to the invention are combined in another embodiment with one or more further cleaning agents. A detergent combination comprising a) a cleaning agent A according to the invention; b) at least one, preferably at least two further cleaning agents other than A.

The further cleaning agents combined with the cleaning agent according to the invention are preferably detergents containing enzyme and / or surfactants and / or builders.

The separation of the cartridge and dosing device, for example, the filling of the cartridge is simplified. Alternatively, the detachable connection of cartridge and dispenser allows the replacement of the cartridges on the dispenser.

Preferred detergent combinations for use in such Reinigungsmittelangebots- forms can be found in Table 8 above.

Of course, detergent forms are also conceivable in which the cartridge and the dosing device are permanently connected to each other.

A subject matter of the present application is furthermore a detergent dosing system, comprising a) a cleaning agent A according to the invention in an amount sufficient for at least twice, preferably at least four, and in particular at least eight times, carrying out a machine dishwashing process; b) a cartridge for the cleaning agent A; c) a metering device undetachably connected to the cartridge.

The vorgenanten Reinigungsmitteldosiersysteme, comprising a cleaning agent according to the invention (and optionally one or two further, different from the cleaning agent according to the invention cleaning), a cartridge and a releasably connected to the cartridge dosing device are in a preferred embodiment in a common outer packaging, wherein the filled cartridge and the dosing device are particularly preferably contained separately from one another in the outer packaging. The outer packaging is used for storage, transport and presentation of the invention Reinigungsmitteangebotsform and protect them from dirt, shock and shock. In particular for the purpose of presentation, the outer packaging should at least partially be made transparent.

Alternatively or in addition to an outer packaging, it is of course possible to market the inventive detergents, detergent combinations or detergent product forms in conjunction with a dishwasher. Such a combination is particularly advantageous in cases in which the course of the automatic dishwashing process (for example duration, temperature profile, water supply) and the detergent formulation or the control electronics of the dosing device are matched to one another.

The dosing system according to the invention consists of the basic components of a cartridge filled with the detergent according to the invention and a metering device which can be coupled to the cartridge, which in turn is formed from further assemblies such as component carrier, actuator, closure element, sensor, energy source and / or control unit.

It is preferred that the metering system according to the invention is mobile. Movable in the sense of this application means that the metering system is not inseparably connected to a water-conducting device such as a dishwasher, washing machine, tumble dryer or the like, but for example from a dishwasher by the user removed or positionable in a dishwasher, so is independently handled, is According to an alternative embodiment of the invention, it is also conceivable that the dosing device for the user is not detachably connected to a water-carrying device such as a dishwasher, washing machine, tumble dryer or the like and only the cartridge is movable.

Since the preparations to be dosed may have a pH between 2 and 12, depending on the intended use, all components of the dosing system which come into contact with the preparations should have a corresponding acid and / or alkali resistance. Furthermore, these components should be largely chemically inert by a suitable choice of material, for example against nonionic surfactants, enzymes and / or fragrances.

cartridge

For the purposes of this application, a cartridge is understood as meaning a packaging material which is suitable for enveloping or holding together flowable or spreadable preparations and which can be coupled to a dosing device for dispensing the preparation.

In particular, a cartridge can also comprise a plurality of chambers which can be filled with mutually different compositions. It is also conceivable that a plurality of containers is arranged to form a cartridge unit.

It is advantageous that the cartridge has at least one outlet opening, which is arranged such that a gravity-induced release of preparation from the container in the position of use of the dosing device can be effected. As a result, no further funding for the release of preparation from the container is required, whereby the structure of the metering device can be kept simple and the production costs low.

In a preferred embodiment of the invention, at least one second chamber is provided for receiving at least one second flowable preparation, the second chamber having at least one outlet opening arranged such that a gravity-induced product release from the second chamber in the use position of the dosing is effected. The arrangement of a second chamber is particularly advantageous if in the separate containers preparations are stored, which are usually not stable to each other, such as bleaching agents and enzymes.

Furthermore, it is conceivable that more than two, in particular three to four chambers are provided in or on a cartridge. In particular, one of the chambers can be designed for the delivery of volatile preparations, such as a fragrance to the environment. In a further embodiment of the invention, the cartridge is integrally formed. In this way, the cartridges, in particular by suitable blow molding, cost-effectively trained in a manufacturing step. The chambers of a cartridge can in this case be separated from one another, for example, by webs or material bridges.

The cartridge can also be formed in several pieces by injection molded and then assembled components.

Further, it is conceivable that the cartridge is formed in such a multi-piece, that at least one chamber, preferably all chambers, can be removed individually from the metering device or inserted into the metering device. This makes it possible, with a different consumption of a preparation from a chamber to exchange an already empty chamber, while the rest, which may still be filled with preparation, remain in the metering device. Thus, a targeted and needs-based refilling the individual chambers or their preparations can be achieved.

The chambers of a cartridge can be fixed to one another by suitable connection methods, so that a container unit is formed. The chambers can be fixed by a suitable form-fitting, non-positive or cohesive connection releasably or permanently against each other. In particular, the fixation by one or more of the types of compounds from the group of snap-in compounds, Velcro, press joints, fusions, glued joints, welded joints, solder joints, screw, wedge, clamp or bounce joints can be done. In particular, the fixation can also be formed by a shrink sleeve (so-called sleeve), which is pulled in a heated state over the entire or sections of the cartridge and firmly encloses the chambers or the cartridge in the cooled state.

To provide advantageous residual emptying characteristics of the chambers, the bottom of the chambers may be funnel-shaped inclined towards the discharge opening. Furthermore, the inner wall of a chamber can be formed by suitable choice of material and / or surface design in such a way that a low material adhesion of the preparation to the inner chamber wall is realized. Also by this measure, the residual emptiness of a chamber can be further optimized.

The chambers of a cartridge may have the same or different filling volumes. In a two-chamber configuration, the ratio of container volumes is preferably 5: 1, with a three-chamber configuration it is preferably 4: 1: 1, and these configurations are particularly suitable for use in dishwashers. As mentioned above, the cartridge preferably has 3 chambers. For the use of such a cartridge in a dishwasher, it is particularly preferred that the first chamber contains an alkaline cleaning preparation, the second chamber contains an enzymatic preparation and the third chamber contains a rinse aid, wherein the volume ratio of the chambers is approximately 4: 1: 1.

In or on a chamber, a metering chamber may be formed in the flow direction of the preparation in front of the outlet opening. Through the metering chamber, the preparation amount that is to be released in the release of preparation from the chamber to the environment, set. This is particularly advantageous when the closure element of the dosing device, which causes the preparation discharge from a chamber to the environment, only in a dispensing and a closure state without control of the dispensing amount can be added. It is then ensured by the metering chamber that a predefined amount of preparation is released without an immediate feedback of the delivered preparation amount. The metering chambers can be formed in one piece or in several pieces.

According to a further advantageous development of the invention, one or more chambers in addition to an outlet opening each have a liquid-tight sealable chamber opening. Through this chamber opening, it is possible, for example, to refill stored in this chamber preparation.

For ventilation of the cartridge chambers ventilation possibilities can be provided in particular in the head region of the cartridge in order to ensure a pressure equalization with decreasing filling level of the chambers between the interior of the cartridge chambers and the environment. These ventilation options can be designed, for example, as a valve, in particular silicone valve, micro-openings in the cartridge wall or the like.

According to another embodiment, the cartridge chambers should not be aerated directly, but via the dosing device or no ventilation, e.g. be provided with the use of flexible containers, such as bags, so this has the advantage that at elevated temperatures in the course of a rinse cycle of a dishwasher by the heating of the chamber contents, a pressure is built up, which presses the preparations to be dosed in the direction of the outlet openings, so that a good residual emptying of the cartridge can be achieved. Furthermore, in the case of such an air-free packaging, there is no risk of oxidation of substances of the preparation, which makes bag packaging or else bag-in-bottle packaging appear expedient, in particular for oxidation-sensitive preparations.

The cartridge usually has a filling volume of <5,000 ml, in particular <1,000 ml, preferably <500 ml, more preferably <250 ml, most preferably <50 ml. The cartridge can take on any spatial form. It can for example be cube-shaped, spherical or plate-like.

The cartridge and the dosing device can in particular be configured with respect to their spatial form such that they ensure the least possible loss of useful volume, in particular in a dishwasher.

To use the dispenser in dishwashers, it is particularly advantageous to mold the device based on dishes to be cleaned in dishwashers. So this example, plate-shaped, be formed in approximately the dimensions of a plate. As a result, the metering device can save space, e.g. be positioned in the lower basket of the dishwasher. Furthermore, the correct positioning of the dosing unit opens up to the user intuitively through the plate-like shape. The cartridge preferably has a ratio of height: width: depth between 5: 5: 1 and 50: 50: 1, particularly preferably about 10: 10: 1. Due to the "slim" design of the dosing device and the cartridge, it is in particular possible to position the device in the lower cutlery basket of a dishwashing machine in the receptacles provided for plates This has the advantage that the preparations discharged from the dosing device pass directly into the wash liquor and can not adhere to other items to be washed.

Usually, commercial household dishwashers are designed in such a way that the arrangement of larger items to be washed, such as pans or large plates, is provided in the lower basket of the dishwasher. In order to avoid a non-optimal positioning of the metering by the user in the upper basket, the metering system is dimensioned in an advantageous embodiment of the invention such that a positioning of the metering system is only possible in the receptacles provided for the lower basket. For this purpose, the width and the height of the metering system can be selected in particular between 150 mm and 300 mm, particularly preferably between 175 mm and 250 mm.

However, it is also conceivable to form the metering unit in cup shape with a substantially circular or square base.

In order to protect heat-sensitive components of a preparation in a cartridge from heat, it is advantageous to produce the cartridge from a material with a low thermal conductivity.

Another way to reduce the influence of heat on a preparation in a chamber of the cartridge is to isolate the chamber by suitable measures, for example by the Use of thermal insulation materials such as polystyrene, which surround the chamber or the cartridge in a suitable manner, in whole or in part.

In a preferred embodiment of the invention, the cartridge has an RFID tag that contains at least information about the contents of the cartridge and that can be read by the sensor unit.

This information can be used to select a dosing program stored in the control unit. In this way it can be ensured that an optimal dosing program is always used for a particular preparation. It can also be provided that in the absence of an RFID label or an RFID label with a false or faulty identifier, no dosage is done by the dosing and instead an optical or acoustic signal is generated that the user on the present Error indicates.

To preclude misuse of the cartridge, the cartridges may also have structural elements which cooperate with corresponding elements of the metering device according to the key-lock principle, so that, for example, only cartridges of a particular type can be coupled to the metering device. Furthermore, this configuration makes it possible for information about the cartridge coupled to the dosing device to be transmitted to the control unit, as a result of which control of the dosing device coordinated with the contents of the corresponding container can take place.

The cartridge is designed in particular for receiving flowable detergents or cleaning agents. Particularly preferably, such a cartridge has a plurality of chambers for the spatially separated receiving in each case of different preparations of a washing or cleaning agent. By way of example, but not exclusively, some possible combinations of the filling of the chambers with different preparations are listed in Tables 1 to 8 above in the description.

The cartridge may be designed so that it can be detachably or firmly arranged in or on the dishwasher.

dosing

The control unit, sensor unit and at least one actuator necessary for operation are integrated in the dosing device. Preferably, an energy source is also arranged in the metering device. Preferably, the metering device consists of a splash-proof housing, which prevents the penetration of spray water, as may occur, for example, when used in a dishwasher, into the interior of the metering device.

It is particularly preferred that the dosing device comprises at least a first interface, which in or on a water-conducting device such as in particular a water-conducting household appliance, preferably a dishwashing or washing machine formed corresponding interface cooperates in such a way that a transfer of electrical energy from the water-bearing device realized for dosing.

In one embodiment of the invention, the interfaces are formed by connectors. In a further embodiment, the interface cells can be designed in such a way that a wireless transmission of electrical energy is effected.

In an advantageous further development of the invention, in each case a second interface on the dosing device and the water-conducting device, such as a dishwasher, for transmitting electromagnetic signals, which in particular Betriebszustandands-, measuring and / or control information of the dosing and / or the water-bearing device such as Dishwasher represent trained.

adapter

By means of an adapter, a simple coupling of the dosing system with a water-conducting domestic appliance can be realized. The adapter serves for the mechanical and / or electrical connection of the metering system with the water-conducting household appliance.

The adapter is, preferably fixed, connected to a water-carrying pipe of the household appliance. However, it is also conceivable to provide the adapter for positioning in or on the household appliance, in which the adapter is detected by the water flow and / or spray of the household appliance.

The adapter makes it possible to carry out a dosing system both for a stand-alone version and a build-in version, and it is also possible to design the adapter as a charging station for the dosing system in which, for example, the dosing device's energy source is charged or data is transferred be exchanged with the dosing device and the adapter.

The adapter can be arranged in a dishwasher on one of the inner walls of the washing chamber, in particular on the inner side of the dishwasher door. However, it is also conceivable that the adapter is positioned as such inaccessible to the user in the water-conducting domestic appliance, so that the dosing device, for example, during assembly with the domestic holding device is inserted into the adapter, wherein the adapter, the dosing device and the household appliance are designed in such a way that a cartridge can be coupled by the user with the dosing device.

The metering chamber inlets 21a, 21b furthermore have means which, when the cartridge 1 is pushed onto the metering device 2, open the outlet openings 5a, 5b of the chambers 3a, 3b, so that the interior of the chambers 3a, 3b communicates with the metering chamber inlets 21a, 21 b is connected.

The cartridge 1 may consist of one or more chambers 3a, 3b. The cartridge 1 may be integrally formed with a plurality of chambers 3a, 3b or more pieces, in which case the individual Chambers 3a, 3b are joined together to form a cartridge 1, in particular by cohesive, positive or non-positive connection methods.

In particular, the fixation by one or more of the types of compounds from the group of snap-in compounds, compression joints, fusions, adhesive bonds, welded joints, solder joints, screw, wedge, clamp or bounce joints can be done. In particular, the fixation can also be formed by a shrink sleeve (so-called sleeve), which is pulled in a heated state at least in sections over the cartridge and firmly encloses the cartridge in the cooled state.

In order to provide advantageous residual emptying properties of the cartridge 1, the bottom of the cartridge 1 may be funnel-shaped inclined to the discharge opening 5a, 5b. Furthermore, the inner wall of the cartridge 1 can be formed by suitable choice of material and / or surface design in such a way that a low material adhesion of the product to the inner cartridge wall is realized. Also by this measure, the residual emptying of the cartridge 1 can be further optimized.

The chambers 3a, 3b of the cartridge 1 may have the same or different filling volumes. In a two-chambered configuration 3a, 3b, the chamber volume ratio is preferably 5: 1, in a 3-chamber configuration it is preferably 4: 1: 1, which configurations are particularly suitable for use in dishwashers. A connection method can also be that the chambers 3a, 3b are inserted into one of the corresponding metering chamber inlets 21a, 21b of the metering device 2 and thus fixed against each other.

The connection between the chambers 3a, 3b may in particular be made detachable in order to allow a separate exchange of a chamber.

The chambers 3a, 3b each contain a preparation 40a, 40b. The preparation 40a, 40b may have the same or different composition.

Advantageously, the chambers 3a, 3b are made of a transparent material, so that the filling level of the preparations 40a, 40b is visible from the outside by the user. However, it may also be advantageous to manufacture at least one of the chambers from an opaque material, in particular when the preparation contained in this chamber contains light-sensitive ingredients. The outlet openings 5a, 5b are designed such that they form a positive and / or non-positive, in particular liquid-tight, connection with the corresponding metering chamber inlets 21a, 21b.

It is particularly advantageous that each of the outlet openings 5a, 5b is formed so that it fits only one of the Dosierkammereinlässe 21a, 21b, thereby preventing a chamber is accidentally plugged onto a wrong Dosierkammereinlass.

The cartridge 1 usually has a filling volume of <5,000 ml, in particular <1,000 ml, preferably <500 ml, more preferably <250 ml, most preferably <50 ml.

The metering unit 2 and the cartridge 1 can be adapted in the assembled state in particular to the geometries of the devices or in which they are applied in order to ensure the least possible loss of useful volume. To use the dosing unit 2 and the cartridge 1 in dishwashers, it is particularly advantageous to mold the dosing unit 2 and the cartridge 1 on the basis of dishes to be cleaned in dishwashers. Thus, the dosing unit 2 and the cartridge 1, for example, plate-shaped, be formed in approximately the dimensions of a plate. As a result, the dosing unit can be positioned to save space in the lower basket.

To provide an immediate optical level control, it is advantageous to form the cartridge 1 at least in sections of a transparent material.

In order to protect heat-sensitive components of a product contained in a cartridge from heat, it is advantageous to produce the cartridge 1 from a material with a low thermal conductivity.

The outlet openings 5a, 5b of the cartridge 1 are preferably arranged on a line or in alignment, whereby a slender, plate-shaped design of the dosing dispenser is made possible.

FIG. 2 shows a self-sufficient dosing device with a two-chamber cartridge 1 in the dish drawer 11 with the dishwasher door 39 of a dishwasher 38 open.

Figure 3 shows a two-chamber cartridge 1 in the separated state to a self-sufficient dosing device 2 and an internal, machine-integrated dosing. In this case, the cartridge 1 is designed in such a way that it can be coupled both to the self-sufficient dosing device 2 and to the machine-integrated dosing device (not shown), which is indicated by the arrows illustrated in FIG. A recess 43 into which the cartridge 1 can be inserted is formed on the side of the dishwasher door 39 directed inside the dishwasher 38, the outlet openings 5a, 5b of the cartridge 1 communicating with the adapter pieces 42a, 42b being connected by insertion. The adapter pieces 42a, 42b are in turn coupled to the machine-integrated dosing device.

For fixing the cartridge 1 in the recess 43 holding elements 44a, 44b may be provided on the recess 43, which ensure a positive and / or positive fixing of the cartridge in the recess 43. Of course, it is also conceivable that corresponding retaining elements are provided on the cartridge 1. The holding elements 44a, 44b may preferably be selected from the group of snap connections, latching connections, snap-lock connections, clamping connections or plug-in connections.

During operation of the dishwasher 38, preparation 40a, 40b from the cartridge 1 through the adapter elements 42a, 42b is added to the corresponding rinsing cycle by the machine-integrated dosing device.

Figure 4 shows the error! Reference source could not be found, known cartridge 1 in the installed state in the door 39 of a dishwasher 38th

Another embodiment of the invention is shown in FIG. FIG. 5 shows the cartridge 1 known from FIG. 3 with a chamber 45 arranged at the head of the cartridge 1, which chamber has a plurality of openings 46 in its lateral surface. Preferably, the chamber 45 is filled with an air freshener formulation which is delivered through the openings 46 to the environment. The air-conditioning preparation may in particular comprise at least one fragrance and / or an odor-controlling substance.

Unlike the arrangement of the cartridge 1 in the interior of a dishwasher 38 known from FIGS. 3 and 4, it is also possible to provide a recess 43 with adapter elements 42a, 42b for coupling to the cartridge 1 on an outer surface of a dishwasher 38. This is shown by way of example in FIG. 5 and FIG.

Of course, the cartridge 1 depicted in FIG. 5 and FIG. 6 can also be arranged with a chamber 45 containing an air-improving substance in a correspondingly formed receptacle in the interior of a dishwasher 38.

A further embodiment of the invention is shown in FIG. The dosing device 2 can in this case be coupled to the cartridge 1, which is indicated by the first, left-hand arrow in the drawing. is interpreted. Subsequently, cartridge 1 and dosing device 2 are coupled as an assembly via the interface 47, 48 to the dishwasher, which is indicated by the right arrow. The dosing device 2 has an interface 47, via which data and / or energy are transferred to and / or from the dosing device 2. In the door 39 of the dishwasher 38, a recess 43 for receiving the dosing device 2 is provided. In the depression 43, a second interface 48 is provided, which transmits data and / or energy to and / or from the dosing device 2.

Preferably, data and / or energy are exchanged wirelessly between the first interface 47 on the dosing device 2 and the second interface 48 on the dishwasher 38. It is particularly preferred that energy from the interface 48 of the dishwasher 38 is transmitted wirelessly via the interface 47 to the dosing device 2. This can be done, for example, inductively and / or capacitively.

It is also advantageous to form the interface for transmitting data wirelessly. This can be realized by the methods known in the prior art for the wireless transmission of data, such as by means of radio transmission or IR transmission.

Alternatively, the interfaces 47, 48 may be formed by integrated connectors. Advantageously, the connectors are formed in such a way that they are protected from the entry of water or moisture.

FIG. 9 shows a cartridge 1 whose chambers 3a, 3b can be filled via the head-side openings 49a, 49b, for example by means of a refill cartridge 51. The openings 49a, 49b of the cartridge 1 may be formed, for example, as silicone valves, which open when piercing through the adapter 50a, 50b and close again upon removal of the adapter 50a, 50b, so that an inadvertent leakage of preparation from the cartridge is prevented.

The adapters 50a, 50b are formed in such a way that they can pierce the openings 49a, 49b of the cartridge 1. Advantageously, the openings 49a, 49b of the cartridge 1 and the adapters 50a, 50b are configured with regard to their position and size in such a way that the adapter can engage in the openings 49a, 49b only in a predefined position. In this way, in particular, incorrect filling of the cartridge chambers 3a, 3b can be prevented and it is ensured that the respectively identical or compatible preparation passes from a chamber 52a, 52b of the refill cartridge 51 into the corresponding chamber 3a, 3b of the cartridge 1.
