Abstract

The dishwasher (1) has a control unit for supplying cleaning agents to a rinsing chamber (2), and a sensing unit for detecting constituents of rinsing water moving in the rinsing chamber and an associated line system, where the detected data adjusts dosing of the cleaning agents. The sensing unit comprises a sensor array or a lab on chip supplied with the rinsing water, and the cleaning agents are stored in a cartridge (7) inserted into the rinsing chamber. The control unit influences the cartridge regarding delivery time and/or delivery amount of the cleaning agents.

Description

The invention relates to a dishwasher, in particular household dishwashing machine, with a washing compartment, wherein cleaning agents can be fed in a dosed manner into the washing compartment by means of a control unit.

It is known in dishwashers, in particular before start-up to carry out a measurement of the degree of hardness of rinsing water to be introduced into the washing compartment and to adjust the detergent dosing to the measured water hardness. However, this means that there is only an inaccurate adaptation to the actually required quantities of cleaning agent, so that considerable incorrect dosages occur. As a remedy z. B. provided to adjust the required amounts of detergent for safety's sake as overdoses, so that the user finds clean dishes or the like after the rinse in any case.

The invention is based on the problem of achieving an improvement here.

The invention solves this problem by a dishwasher with the features of claim 1 and by a cartridge having the features of claim 16 and / or 17.

Characterized in that, in particular in the rinsing operation of the dishwasher, components of the rinse water are detected, information about the actual nature of the rinse water can be obtained as an instantaneous value and the control for the further detergent supply during operation can be adapted thereto. In particular, such measurements can be carried out several times during the rinsing operation in order to achieve an optimized metering for different phases of cleaning agents.

According to an expedient embodiment variant of the invention, cleaning agent can be stored particularly expediently in a cartridge which can be inserted into the washing compartment and which comprises one or preferably several storage spaces and can be influenced by a control unit with respect to its dispensing times and / or quantities of cleaning agents. With the o. G. multiple measurements during the wash cycle can be achieved for various contained in the reservoirs of the cartridge detergent optimized dosing adjustment.

The control unit or the control unit for the metered supply of detergent or cleaning agents in the washing compartment of the dishwasher can, for. B. change the opening times of outlet valves of the cartridge and / or vary an order of control of individual storage chambers of the cartridge by opening of respective exhaust valves with the received input data for dirt type.

In particular, ingredients of the rinsing water, preferably depending on the type of dirt introduced by the dishes, can be detected by the at least one sensor unit. Thus, for example, with only slight total contamination, the amount of the supplied detergent can be reduced overall.

A high accuracy of the addition can be achieved especially if different ingredients in particular are distinguishable from the sensor unit.

For example, dyes may be detectable in the rinse water, in addition or alternatively also fats, proteins and / or starch. Depending on their concentration, the metered addition of cleaning agents can then be selectively adjusted, with particular alkali carriers, eg. As alkalis, complexing and dispersing agents, enzymes such. As amylase, protease and / or lipase, bleach, bleach activators, surfactants, biocides and / or water surface tension reducing rinse aid come into question. The various cleaning agents can be stored in individual chambers of the cartridge and depending on the result of the currently detected by the sensor unit ingredients in the rinse water this fully automatically fed in adjusted dosing. A misdosing is thus avoidable; it results in a maximum efficiency of the utilization of the respective cleaning agent and the required energy and minimizing the duration of a wash cycle.

For a special resource conservation is achieved, in particular an optimized and thus reduced use of chemicals and energy, a reduction in water consumption and the time required for the flushing process.

In this case, it is particularly favorable for the sensor unit to perform not only a qualitative, but in particular also a quantitative detection with which the concentration of ingredients of the rinsing water is detected.

According to an advantageous development of the invention, the sensor unit particularly advantageously comprises at least at least one "lab-on-a-chip" which can be flown with the rinse water currently present in the rinsing liquor and therefore record current data such as the amount and / or type of contamination can. Such "lab-on-chips", for example, protein chips, consume over time, so it is convenient to place them in a space of the cartridge to arrange and replace with this after consumption of cleaning agents.

In this case, the cartridge can in particular possibly be assigned its own energy supply. The acquired data can be transmitted without contact, for example via a transponder or a similar Nahfunktechnik to the control unit of the dishwasher.

Alternatively, the cartridge can be connectable via electrical contacts as an interface with a reading device and / or a power supply of the dishwasher.

For an inexpensive production is an arrangement of multiple sensors in a multi-sensor module, d. H. "Sensor array", cheap. In this chemical and water-parametric sensors can be integrated, for example, at the same time the type of dirt (such as fats, spinach, starch, tea ...) and water parameters (such as hardness, pH value ...) and their reaction products, which arise in conjunction with the introduced detergents and the corresponding temperature, detect.

Furthermore, according to a further advantageous embodiment of the invention, one or more marker substances can be contained in the cartridge, which can be introduced into the rinse water during operation, the dishwasher being assigned a detection unit for detecting the one or more marker substances or their reaction products. This detection unit may in particular be provided with at least one UV light source and one or more photodiodes for detecting fluorescence or phosphorescence light and also forward the acquired data to a control unit. The detection unit may in particular also be accommodated in the cartridge. Additionally or alternatively, the detection unit may be arranged at a location in the piping system of the flushing water, in particular in the pump sump. As a result, the ingredients such. B. Soil type, reaction products dirt / cleaner, detect water constituents in the rinse water. If, in addition or independently, such a detection unit is provided in the washing compartment of the washing container, in particular also the dirt particles adhering to the items to be cleaned can be analyzed, preferably with regard to their type and / or concentration.

The invention also relates to a cartridge which can be filled or pre-filled with one or more cleaning agents and has at least one sensor unit for detecting constituents of the flushing water moved in the flushing space and / or an associated piping system, wherein the recorded data for setting a dosage of cleaning agents from the cartridge are usable.

Furthermore, the invention also relates to a cartridge which can be filled or pre-filled with one or more cleaning agents and which comprises one or more reservoir chambers with one or more marker substances, which can be dispensed via at least one outlet opening during at least one partial flushing operation.

Other advantageous embodiments and / or developments of the invention are given in the dependent claims. The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the subclaims can be used individually or else in any desired combination with one another in the dishwasher and / or cartridge according to the invention.

The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings.

Show it:

1 a schematic view of a dishwasher in a possible advantageous embodiment of the invention, wherein by way of example two possible arrangements for receiving spaces of a cartridge are indicated here,

2 an itemized view of the sake of clarity better unfilled and not provided with valves cartridge, approximately corresponding to the detail II in 1 wherein the cartridge has a transponder that can wirelessly transmit via RFID technology, and wherein the cartridge has a sensor module that can be flushed by rinsing water within a chamber,

3 in a similar view as in 2 an alternative cartridge, which additionally has a chamber for receiving and delivering marker substances to the rinsing liquor,

4 in a similar view as in 2 another alternative cartridge, which has a chip and is connected via electrical plug-in contacts with the dishwasher, and

5 a similar cartridge as in 2 with valves inserted therein.

Elements with the same function and mode of action are in the 1 With 5 each provided with the same reference numerals.

A dishwasher according to the invention can form a standalone or a built-in or installable device, such as within a kitchenette.

In the 1 Dishwasher shown schematically 1 is a household dishwasher with a dishwasher 2 for holding and cleaning dishes, cutlery, cooking utensils or the like. The dishwasher 2 is essentially cuboid and on five of its six outer surfaces of walls 3 a rinse container 21 the dishwasher and to the front of a door 4 bounded, here only by way of example in its lower portion pivotally mounted on a housing of the dishwasher 1 is articulated. In the dishwasher 2 may also include one or more rotatable spray arms (not shown) or other sprayers for distributing rinse water and multiple baskets 5 be held.

According to the illustrated embodiments, it is provided that in a wall 3 or in the door 4 (in 1 these two possibilities are indicated at the same time) a recording room 6 as a recessed niche for a cartouche 7 is trained. In this recording room 6 is a substantially designed as a rectangular flat body cartridge 7 can be used from above. Alternatively, a cartridge 7 also in a receiving basket 5 or in another holder in the sink 2 be usable. It may possibly also be designed as a loose component, the z. B. can be inserted in a dish rack. It may also be expedient to use the cartridge in a mobile receiving box, which is adjustable as a separate component in the washing compartment of the washing.

The cartouche 7 comprises a plurality of storage spaces V1 to V7 for cleaning agent and here a chamber V8, in which at least one sensor unit E is accommodated with at least one multiple sensor module M. At least the chamber V8 can be flowed through by rinsing water W from the rinsing liquor. The storage rooms V1... V7 can all or partly be filled with solid-state cleaners and / or with liquid and / or gel-type cleaning agents. Such storage rooms, which are filled with solid cleaners, preferably also have an introduction option for rinse water (not shown here). In the storage rooms filled with liquid cleaners, it is not necessary to introduce flushing water, but of course it is also possible. The release of detergents can be done solely by gravity. The sensor module or "sensor array" M could also be on the outside of the cartridge 7 lie in an area acted upon by rinse water W.

Next, the cartridge 7 be designed to be transparent as a plastic body and for easy optical level control. To simplify the manufacturing process, the cartridge 7 be formed in one piece in particular. You can z. B. form a produced in one operation injection molded part or be prepared by an internal gas pressure process. Furthermore, the cartridge 7 for her inclusion in the niche 6 form a flat body. This may for example be preferably 10 to 20 inches wide, a few inches high and especially less than five inches deep.

As described above, contains the cartridge 7 several - here exemplified seven - storerooms or pantries V1 ... V7. These can each be filled with the same detergent. In particular, the plurality of storage chambers can be of the same size. Alternatively, several storage chambers, in particular each different from each other, can be filled with different cleaning agents. The respective filling with the same cleaning agent or different cleaning agents can either be made by the customer, or the cartridge 7 is already pre-filled with the same detergent or different detergents, especially for several to several ten rinses acted. Even with such prefilled to acquire, replaceable, cartridges 7 There may be a refill at the end user itself. Even then, a filling for several rinses, for example, 20 or 30, possible. In any case, it is therefore not necessary to enter cleaners or tabs before each wash cycle. The comfort for the customer is thereby improved.

In particular, in each storage room, another cleaning agent may be included, such as pre-cleaner, cleaner with different enzymes, water softener and rinse aid.

As in the 2 to 5 can be seen, the storage rooms or pantries V1 to V7 may have different sizes in order to stock so differently metered detergent so that they are used up at the same time.

According to the illustrated embodiment, each storage space V1 ... V7 is a metering chamber or a metering chamber D1 ... D7 specifically downstream, the or with detergent (s) from the associated storage space V1 ... V7 can be filled and from which the filled Cleaning agent via an outlet opening A1 ... A7 to the washing compartment 2 is deliverable. It is not mandatory that each pantry is equipped in such a way, but In particular, in such pantries, which are provided for receiving solid-state cleaners, and a bottom of the pantry without underlying dosing can be provided only with openings. With an upright bracket of the cartridge 7 in the dishwasher 1 the leakage of the detergent from the storage space V1 ... V7 in the dosing D1 ... D7 gravity driven, as well as the further outlet in the washing compartment, if - as shown here - the metering chambers are arranged below the storage rooms.

The dosing chambers D1 ... D7 are here as well as the valves S1 ... S7 part of the cartridge 7 which is not mandatory.

In 5 It becomes clear that an outlet valve S1... S7 between a refilling position releasing the passage of detergent from the respective storage space V1... V7 into the specifically downstream metering space D1... D7 and a discharge of cleaning agent from the metering space into the Wash cabinet 2 releasing outlet position (shown here at the passage space D3) is movable.

In this case, each of the same outlet valve S1 ... S7 both the passage of detergent from the respective pantry V1 ... V7 in the downstream of him dosing D1 ... D7 and the exit of detergent from the respective dosing into the washing compartment 2 controllable.

Here in the exemplary embodiment, the valves between the two said positions, which simultaneously form an upper and a lower extreme position of a stroke movement of the respective valve, by means of an actuator acting on each valve actuator of the dishwasher 1 or the cartridge 7 acted upon.

When the passage from the respective storage space (for example V1) to the respective associated metering space (for example D1) is opened via the downwardly displaced valve S1, at the same time an outlet opening (such as A1) is directly into the washing space 2 or in a lower sump, from which detergent can get into the washroom, sealed. Conversely, in the 5 By way of example, in the storage space V3 the passage into the associated, downstream metering space D3 is closed via the upwardly displaced valve S3, but at the same time the outlet opening A3 of the metering space D3 is opened, so that here cleaners from the metering chamber D3 into the flushing space 2 can arrive without a run on from the storage room V3 would be possible. For such a refilling of the dosing chamber D3, only a renewed valve lift of the valve S3 would be required. The per supply and downstream Dosierraumpaar only one valve is thus in a double function between the flow from the respective storage space V1 ... V7 in the respective associated metering D1 ... D7 releasing refill and one the passage or outlet of detergent from the respective dosing D1 ... D7 in the washing compartment 2 releasable outlet position movable.

The movement of the respective valve can be counter to the force of a downwardly pressing spring 12 , which sits here in the respective storage space, by means of an associated actuator - not shown here - in which the outlet opening of the respective metering space releasing sense done. These actuators can act like plungers.

As in further 5 is shown, the outlet valves S1 ... S7 in mounted position of the cartridge 7 held at an angle of at least 20 ° to the vertical or gravity direction and in particular at an angle of at least 20 ° to the horizontal inclined. As a result, when leakage of detergent from the respective dosing such. B. D3 in the dishwasher 2 Air in the metering room such. B. follow D3 and the subsequent valve lift of the valve such as S3 by means of its spring element 12 down to close the outlet opening such. B. A3 of the dosing such. B. D3 air in the storage room such. B. V3, so that there is a negative pressure is prevented even without further ventilation opening and detergent alone by its gravity from the storage room can run into the dosing. The cartouche 7 is thus particularly inexpensive to produce and due to the lack of other openings also very safe against unwanted skin contact with the partially aggressive cleaning agents.

Each of the valves S1 ... S7 is separate from a control unit 8th switchable (see eg 2 ). The control unit is formed in particular by the program sequence control device of the dishwasher. Through the control unit 8th is a very fine and needs-based dosage of individual cleaner components so possible that compared to conventional solutions considerable savings in cleaner and energy can be achieved. For example, with the in the control unit 8th Evaluated data of the sensor unit E depending on the current contamination of the rinse water, the appropriate enzymes from the different storage rooms V1 ... V7 be added. It can also be detected via the sensor unit E, when a sufficient clarification of the rinse water has occurred that rinse aid can be added in the final phase of the rinse cycle. The dosage can thus be significantly reduced and specified. In the central control unit 8th the dishwasher 1 For this purpose, different rinse programs with different Opening times and / or opening periods of the respective valves S1 ... S7 stored. The control unit can in particular operate fully electronically and use data transmitted by the sensor unit E as input data for different rinse programs. Other input data, such as hardness, temperature, information on the concentration and effect of the respective cleaners, can also be taken into account. The sensor unit may contain various components of the washing compartment 2 and / or an associated piping system moving rinse water during operation and capture this data for adjustment to the control unit 8th to control the dosage of different detergents.

In this case, information on the amount of contamination and the type of contamination of the introduced dishes or the like can ideally be obtained in particular by way of the detection of ingredients of the rinse water.

For example, dyes may be detectable in the rinse water, additionally or alternatively also fats, spinach, tea, egg whites and / or starch. Depending on their concentration, the metered addition of cleaning agents can then be selectively adjusted, with particular alkali carriers, eg. As alkalis, complexing and dispersing agents, enzymes such as amylase, protease and / or lipase, bleaching agents, bleach activators, surfactants, biocides and / or the water surface tension reducing rinse aid come into question. Depending on the result of the sensor unit. E currently detected ingredients of the rinse water W, the control unit 8th react automatically and practically without time delay and adjust the dosage. Also, other water parameters, such. B. temperature and hardness of the rinse water, are detected by the multiple sensor module M. It is also possible to determine chemical reaction products that are associated with the cleaning chemistry and the temperature.

The sensor unit E preferably comprises one or more "lab-on chips" which are known from medical technology and are also referred to as biochips or protein chips. They can be designed in particular as sensor arrays. These "lab-on-chips" are here with each currently in the rinsing liquor located Spülwasser W wettrömbar and can thereby record current data, such as pollution amount and type. Such "lab-on-chips", for example, protein chips, consume themselves over time, so it is convenient to place them in a space of the cartridge 7 to arrange and replace with this after consumption of cleaning agents. The entire sensor unit E can therefore be fixedly arranged in a space V8. If the cleaning agents are used up, for example, after 20 or 30 rinses, therefore, the cartridge 7 be completely disposed of with the sensor unit E. The space V8 is open at the top, for example, whereby a direct inlet of rinse water W from the washroom 2 or from a piping system above the cartridge 7 is possible.

Also, the sensor unit E with its own power supply in the cartridge 7 be provided, for example, a button cell 9 , Alternatively, it is also possible to use the energy from the dishwasher 1 to use, especially with a fixed electrical connection 16 between this and the cartridge 7 (please refer 4 ).

In 2 is shown that of the sensor unit E in the cartridge 7 recorded data contactless of one of the dishwasher 1 associated reader 11 are readable. For this includes the cartridge 7 a readable transponder 10 which can be active or passive, ie, that has its own power supply to the cartridge 7 with the transponder 10 not mandatory, but possible.

Alternatively, according to 4 the cartouche 7 via electrical contacts 16 connectable with a reading device and / or a power supply of the dishwasher. Here is the otherwise unchanged cartouche 7 an electronic module provided with at least one memory chip, for example, to an external power supply to an interface 17 in the dishwasher 2 is connectable. In this case, the electrical contacting can take place via contact pins, which upon insertion of the cartridge 7 forcibly get into electrical contact, so that incorrect operation is excluded. Again, the data read via the interface are in turn sent to the control unit 8th forwarded to the dishwasher, so that there again a variant already stored with respect to the dosage and the flushing technology can be selected and activated for the flushing process, or it may also be new dosing and program changes or program variants of the memory chip of the cartridge 7 to the main controller 8th be handed over. These programs then directly influence the valve opening times and thus the time and dosage of the cleaning agent, whereby a very good effectiveness with minimal use of cleaning agent is achieved.

Due to the electrical contact, the cartridge 7 also with an energy supply to the dishwasher 1 can connect, here is its own power supply of the cartridge 7 not required, but possible.

In a further embodiment according to 3 are additional or supplementary to Sensor unit E in at least one other chamber - here, for example, the chamber V9 -, into which rinse water W can be introduced during operation, one or more so-called marker substances 13 contain. Of course, the storage chamber can also have a plurality of chambers for the selective storage and addition of marker materials. These marker substances work via fluorescence or phosphorescence according to the following principle:
To large biomolecules can be attached by a chemical reaction, a fluorescent chemical group, which then serves as a sensitive marker for this molecule. The marker substances can be based on organic molecules, such as. As dirt components, chemically react. By a suggestion 14 In particular with UV light, the markers are excited to glow and can thus be detected on the basis of the respective specific wavelength. For example, coupling to spinach produces a green light, while coupling to starch produces a blue light. With this information, the appropriate cleaning agents can then be added from further chambers V2... V6.

The marker materials 13 can also be added from the chamber V9 controlled during the rinse cycle.

The light stimulation 14 and also a detection unit 15 for detecting the marker substances or their reaction products is the dishwasher 1 assigned and in 1 by way of example in a lower area of the door 4 located.

This registration unit 15 is with a UV light source 14 and photodiodes arranged, for example, in an array, for detecting fluorescent or phosphorescent light. This detection unit is arranged in particular at a point in the line system of the dishwashing machine of the rinsing water, in particular in the pump sump. As a result, the ingredients such. B. Soil type, reaction products dirt / cleaner, detect water constituents in the rinse water. If, in addition or independently, such a detection unit is provided in the washing compartment of the washing container, in particular also the dirt particles adhering to the items to be cleaned can be analyzed, preferably with regard to their type and / or concentration.

Alternatively, it is also possible to equip the cartridge itself with such a detection unit.

In all embodiments, refillability of the cartridge by the customer may be possible. Also, the cartridge can be traded as a tightly closed body, which is returned after use in about 20 to 40 rinses and factory to refill or is then disposed of completely. In these variants, the user is also given maximum protection against skin contact with a cleaning agent and against incorrect operation.

An insertable and filled or unfilled cartouche 7 is claimed separately. It is designed in particular as a replaceable module.

In summary, the following embodiment variants of an interchangeable cartridge designed according to the invention may be expedient in particular:
Advantageously, the integration of a multi-sensor module is provided in the cartridge, which communicates via a discrete interface or a transponder (+ reader) with the main controller or the control unit of the dishwasher. In the sensor module in particular chemical and water-parametric sensors can be integrated with the z. For example, the particular type of soil (such as fats, spinach, starch, tea, etc. ...), water parameters (eg hardness, pH value) and their reaction products, which in conjunction with the cleaning chemistry and the Temperature arise, can be detected.

The sensor module can, for. B. in so-called "lab-on-chip" technology (also known as so-called "biochip" or "protein chip" technology) are executed. This results in a cost-effective system. Since chemical sensors are subject to aging in practice, they can be easily renewed. They are designed in particular as "one-way sensors".

The sensor module is based in particular on the following functional principle:
To large biomolecules can be attached by a chemical reaction, a fluorescent chemical group, which then serves as a very sensitive marker for this molecule. The marker substances can be based on organic molecules, such as. B. dirt components react chemically. By a suggestion z. B. with UV light, the marker excited to light and can be detected by the specific wavelength.

In particular, the following technical embodiment may be appropriate for this purpose:
The marker materials can be stored in the ADS ("Automatic Dosing System") cartridge and added via the ADS dosing device during a rinse phase. The specific wavelengths and their intensity can be detected via photodiode array. As the transmitting unit is in particular at least one UV light source, as a receiver unit is at least one wavelength-selective optical receiver for receiving at least one specific. Wavelength ("fluorescence spectroscopy") provided. Transmitting unit and receiver unit may preferably be combined to form a detection unit. This detection unit can be arranged in the rinsing water for the detection of the ingredients (such as dirt, reaction products dirt / cleaner, water constituents) in the water and / or in the washing compartment for the detection of the dirt particles adhering to the items to be washed.

Advantage of the sensor module:

It is now an adaptation of the dosage and the washing program to the chemical conditions (such as dirt type and amount, water hardness) provided. Furthermore, a resource conservation through the optimized use of chemistry, energy, water consumption, running time, etc. is made possible.
