A transport device (112) transports the dishwasher basket automatically in a transportation direction (116) through the cleaning zone. The dishwasher basket has a contactlessly readable electronic identifier (164), and a reader (166) reads information of the electronic identifier, where the dishwasher is designed to select a parameter of a washing program according to the information. An independent claim is also included for a method for cleaning of cleaning goods using a conveying dishwasher.

Description

Field of the invention

The The invention relates to a continuous dishwashing machine for Cleaning of items to be cleaned and a method for cleaning Cleaned. Such continuous dishwashers and methods are used in particular in the field of commercial dishwashing used, for example, cleaning material of different Type, such as pots, pans, containers, Dinnerware, cutlery, glasses, trays or the like to clean. However, use in other areas is also possible For example, for cleaning medical equipment, care equipment or similar. As an example, here are care equipment in the form of bedding, bedpans or urine bottles.

State of the art

Especially in the field of commercial dishwashing, in which fast and reliable large quantities of items to be cleaned have to be cleaned, have continuous dishwashers proven, in which the cleaning material by means of a transport device is driven through at least one rinsing zone to with there to be acted upon a cleaning liquid. Such continuous dishwashers are, for example, as belt transport machines or as basket pass machines known.

A technical challenge with such continuous dishwashers consists, as with all dishwashers, therein, the Cleaning process optimally adapted to the cleaning material. to Solution to this problem are different from the prior art Methods and devices are known which accomplish this should.

So can be used, for example, basket traversing basket detection devices, which are formed by an arbitrarily designed mechanism. The mechanism is actuated by a passing dish rack, which acts on an electrical switch. This switch in turn acts on a machine control of the dishwasher one. Instead of electrical control switch can be also use magnets, in combination with reed contact switches.

Also Basket detection devices with one or more attached to the basket Magnets, which are not on a mechanical switch, but act directly on an electrical switch, for example a Inductive proximity switches are feasible. To this Way it is possible, for example, a normal basket to distinguish from a basket marked with a magnet. This Method can be used, for example, for baskets, which is especially for rinsing glasses are meant to be distinguished from normal baskets.

These However, known devices have the disadvantage that it means This device is only possible with a magnet To distinguish marked baskets from unmarked baskets. The The amount of data transferred is comparatively low.

The DE 195 14 873 A1 describes, for example, a program-controlled dishwasher for cleaning, disinfecting and drying of items to be cleaned such as breathing tubes, surgical instruments or the like. It is proposed to use the items to be cleaned in a Reinigungsgutkorb, which is introduced into a door-closed washing compartment of the dishwasher. Each basket carries a magnetic key, the magnetization of which determines the washing program for the loaded items to be cleaned. The magnetic key on the car or Reinigungsgutkorb is designed as a magnetic strip of several permanent magnets in a changeable Einzelpolaritätsausrichtung north-south / south-north. In this way, by detecting the magnetic key, a correct program for the basket can be selected.

In the DE 195 14 873 A1 However, the device described is technically relatively expensive. So it is not always possible in a simple manner to equip baskets with a magnet or to retrofit with such magnets due to the different basket designs. Furthermore, the magnetization and the detection of magnets in dishwashers are often disturbed by the fact that the cleaning material is in many cases even magnetic, for example in the form of magnetic cutlery.

Other types of information carriers for identifying the items to be cleaned are therefore known from other areas of dishwashing technology. For example, describes DE 199 17 206 A1 a washer-disinfector for cleaning medical devices or instruments, such as endoscopes. Each individual medical instrument is equipped with a separate data carrier containing its characteristics. All separate data carriers is assigned at least one in, on or outside half of the washing compartment in the machine and associated with the data carriers of the cleaning goods in the data transfer transmitting / receiving device. The individual instruments are in the closed washroom by means of the common or multiple transmitting / receiving devices separated according to type of cleaning product and optionally further cleaning and / or rinse-program specific characteristics recorded and logged. Depending on the characteristic data acquisition, a reprocessing program selected for all the items to be cleaned is then executed.

This in DE 199 17 206 A1 However, the method described is in principle not transferable to the commercial dishwashing technology. A marking, for example, individual plates or cutlery with data carriers is technically practically unrealizable or would involve immense costs that would put the economics of such a method in question.

Object of the invention

It It is therefore an object of the present invention to provide a device and to provide a method by means of which in continuous operation ensures a high degree of flexibility and economy of the dishwasher and which are also easy on existing methods or devices can be retrofitted.

These Task is through a continuous dishwasher as well a method for cleaning items to be cleaned with the features of solved independent claims. advantageous Further developments of the invention, which individually or in combination are realizable are in the dependent claims shown. The proposed method may in particular Use of a continuous dishwashing machine according to the invention carried out so that for possible optional configurations of the method to details of possible embodiments the dishwasher can be referenced.

It is a continuous dishwasher for cleaning Cleaning goods proposed. The cleaning material can in particular Dishes, such as pots, pans, containers, dishes, Include cutlery, glasses, trays or the like, Wherein under dishes basically any kind of Objects are to be understood, which directly or indirectly come in contact with food or drinks or can come. Basically however, the proposed continuous dishwashing machine, as shown above, also for other types of items to be cleaned used. The continuous dishwasher can in particular be used in the commercial sector, so for example in Canteens of schools, businesses, hospitals, authorities, Care facilities or the like.

The Continuous dishwashing machine comprises at least one cleaning zone for charging the cleaning product with at least one cleaning liquid. Preferably, a plurality of such cleaning zones are provided, which arranged, for example, one behind the other in a transport direction could be. For example, one or several of the following cleaning zones are combined: a pre-evacuation zone, a rinse zone, a pump rinse zone, a fresh water rinsing zone. Furthermore you can one or more drying zones to be included, in which the item to be cleaned, for example, with an air flow, for example be subjected to an air flow of elevated temperature can. Other zones may be provided.

The Continuous dishwasher further comprises at least a crockery basket for receiving the cleaning material. This dish basket can at least one piece, preferably a plurality of Pieces of the cleaning material and in particular specially adapted to this type of cleaning material. For example Plastic baskets can be used as baskets use, for example, baskets with a square Base area, for example, with dimensions of about 500 mm × 500 mm and, depending on the purpose, different heights Side walls of, for example, about 100 mm up to about 300 mm, the latter for example for very tall glasses. Basically, the baskets are also made of other materials and / or in other geometry.

The Throughput dishwasher is in total as a basket throughput machine designed. The continuous dishwasher includes a transport device which is arranged to the dish rack automatically in a transport direction through the at least one Transport cleaning zone. This transport device can For example, gears, belts, link chains, rollers, rollers or similar types of transport devices, which, for example, in conventional basket transport machines are provided.

The crockery basket comprises at least one non-contact readable electronic identifier. Thus, this electronic identifier differs for example from the in DE 195 14 873 A1 proposed magnetic keys. An electronic identifier is generally an identifier which can generate at least one electronic signal or can be read out by means of at least one electronic signal. In particular, this electronic identifier may comprise one or more identifiers that can be read electromagnetically. For example, this identifier may be configured to send a response signal in response to an electronic interrogation signal that which is usually called a transponder. This transponder can be equipped with its own power supply, but its energy supply can also be obtained via the interrogation signal, that is configured as a purely passive component. Alternatively or additionally, it is also possible to use so-called high-frequency labels, which are frequently also referred to as RFID labels and which, similarly to a transponder, can likewise be read electromagnetically. Both terms, ie the concept of the transponder and of the high-frequency label, are mostly used synonymously in the literature, as is also the case in the following description. Furthermore, other types of electromagnetically readable identifiers may be present, such as non-contact electromagnetically readable microcomputer, for example cast in a plastic housing. Such microcomputers or microprocessors can also be read out, for example, with the aid of RFID technology.

Of the For example, electronic identifier can be in or on the dish rack be appropriate, for example by non-positive, positive or cohesive connection. For example, the identifier can be affixed to the dish rack, be attached to this or be poured into this. Others too Types of fixation techniques are conceivable.

The Continuous dishwasher still has at least a reader for reading at least one piece of information of the contactless readable electronic identifier on. This reader can, for example, a transponder reader and in particular, the type of electronic identifier be adjusted. In this case, the reader, for example provided at the entrance of the conveyor dishwasher be, for example, at the entrance of a cleaning tunnel of the continuous dishwashing machine. Also several readers can be provided. For example, if several cleaning zones are provided, so can These each have one or more own readers feature. In this case, each individual cleaning zone, for example, over have at least one own reader, which a particularly precise control of a washing program allows. However, other embodiments are possible. Also a drying zone, for example, via a separate Reader.

The at least one information of contactless readable electronic identifier comprises in the simplest case a simple binary 0-1 information. However, one is preferred Higher information depth, so at least 2 bits, for example an information depth of at least 4 bits or at least 8 bits.

The at least one piece of information can basically be any Types of information included, which includes different ones Way can be interpreted. The information can for example, in numerical form, for example in binary form, and accordingly, for example, at least contain a number. Basically, however, are others Types of information possible, such as the simple information that at all an electronic Identifier is within range of the reader.

Especially For example, the at least one piece of information may contain information about a kind of cleaning material received in the dish rack, a Information about a type of contamination of the cleaning material, an information about a degree of contamination of the cleaning or include information about the type of crockery basket.

The Passage dishwasher is set up to at least a parameter of a washing program according to the information to choose. Under a washing program is included to understand generally the type of cleaning of the cleaning material, So for example, the timing of cleaning, the control the at least one cleaning zone, the type and temperature of Cleaning fluid, the cleaning time, the speed or similar. It can also several rinse programs be provided and selectable for example by a user be. Accordingly, the at least one parameter of the washing program, which according to the at least one read information is selected, for example, an adaptation of a transport speed the transport device, a beginning and / or an end of a loading the cleaning product with cleaning liquid in the cleaning zone, a beginning and / or end of a drying of the cleaning product in at least one drying zone of the continuous dishwashing machine, an adaptation of a pump capacity of at least one pump for delivery the cleaning liquid (for example, a circulation pump a Vorabräumzone, a rinsing zone or a Pump rinsing zone), a temperature of the cleaning liquid, a metered amount of a cleaner, a dosage of a chemical Additive or detergent or the like.

The at least one parameter can be changed simultaneously for all cleaning zones if several cleaning zones are specified. However, it is particularly preferred if this at least one parameter is changed in different ways for at least two different cleaning zones. For example, how As described above, different readers may be provided for different cleaning zones, so that in turn, for example, at least one parameter for the respective cleaning zone can be adjusted individually. In particular, depending on the type of cleaning product or the type of contamination level, for example, an exposure time of the cleaning (eg via a transport speed through the respective cleaning zone) and / or another type of parameter can be adapted specifically to this information.

Farther at least one can pass dishwasher Basket counters include. This basket counter can completely or may be partially identical to the reader, however also, alternatively or additionally, for example in one Control of continuous dishwasher integrated be. This basket counter can, according to the information, detect a number of crockery baskets containing the continuous dishwashing machine have passed through, for example, within a given operating period. In this way, for example, profitability calculations create for a machine. In this case, the at least an information example, as shown above, simply the Information includes that a dish rack is a reader happened.

The Profitability calculation can be completely or partially already within the continuous dishwasher or can, alternatively or in addition, even in whole or in part, for example, outside respectively. The dishwasher or a controller The dishwasher can, for example, an interface include. For example, this interface can be used also information about the number of baskets be queried. Currently existing mechanical basket counter work due to the very different basket guides usually only insufficient and are for example on limited to a certain type of dish rack.

Farther The continuous dishwasher can also be a documentation device include. Like the basket counter, this documentation device can for example, in whole or in part in a control of the continuous dishwasher be integrated. The documentation device may, for example implemented wholly or partly in a data processing device be, which can be set up according to program technology. The documentation device is set up for the crockery basket at least one cleaning information about the washing program, which has passed through the dish rack, save. Through the use of such marked baskets So can machine settings of the continuous dishwasher and easily record and save corresponding specifications. The Documentation of certain machine parameters is for example in hygiene-critical areas, such as the geriatric care or in clinics or similar facilities, partially required and is facilitated or enabled by the described method.

The Continuous dishwasher can in particular a plurality differently designed dish racks for include different types of items to be cleaned. Each of these Baskets can be equipped with a readable electronic identifier be provided. These readable electronic identifiers may include, for example, individual identifiers, which identify each dish basket individually, so for example at least one of the readable information of the corresponding Information of another dish basket is different. In this way For example, you can use special washing programs carried out for glasses or the like if the pass-through dishwasher will work accordingly the at least one information recognizes that such a glass dish rack just the dishwasher and / or a specific Cleaning zone of the dishwasher happens.

Provided that the items to be cleaned are correctly inserted into the respectively provided baskets, an automatic adaptation of the dishwasher parameters to the particular item to be cleaned can be carried out in this way. For example, the parameters can be automatically optimized for difficult-to-clean laundry cleaning products. In this way, for example, can reduce the transport speed, increase the pump power, increase a tank temperature of a cleaning liquid tank, increase a detergent dosage, switch on a special intensive treatment by chemical cleaners or the like. The parameters for an optimum rinsing result can be stored for example in a database and / or a memory, for example in an electronic table, a data processing device, a volatile and / or non-volatile memory, a database or the like. The parameters for the optimum washing result and also for the economy of the continuous dishwasher generally depend heavily on the type of cleaning product. For heavily soiled cookware, moderately dirty breakfast and lunch dishes, difficult to clean cutlery or delicate glassware, wine glasses, etc. are usually different sets of parameters considered optimal. By the individual marking of the baskets with, for example, a suitably coded microchip as a contactless readable electronic identifier In many ways, the machine parameters can be adapted to the particular item to be cleaned. The possibilities of incorrect operation, as they can occur, for example, by a manual program selection on the machine control, are thereby almost impossible.

Farther Can the pass-through dishwasher's reading device also be set up to a position of the dish rack in the To recognize continuous flow dishwasher, wherein for position detection For example, again the non-contact readable electronic Identifier can be used. For example, the reader include a certain range of identification within which the information of the identifier can be read out. As soon as an identifier is within this range and accordingly an identification or information available is, the dishwasher can recognize accordingly, that a dish rack is positioned in a certain way, namely within reach. Alternatively or in addition signal strengths can also be evaluated or, for example, more complex positioning determinations be carried out, for example by means of triangulation. For example, each dish rack can contain several Identifiers may be provided whose signal strength is evaluated separately can be. By means of this position detection, for example enables the continuous dishwashing machine be a timing of the washing program according to the To control position. For example, a rinsing process, for example in a Vorabräumzone, a rinsing zone, a pump rinsing zone or a fresh water rinsing zone, then be started when it is detected that a crockery basket on Entrance or already located in this cleaning zone. To this Way can save energy and cleaning fluid Overall, the proposed process is therefore very environmentally sound can be configured. Also the beginning of a drying process, which is usually very energy-intensive, can accordingly to be controlled.

• – ein Start und/oder ein Stopp mindestens einer Pumpe, insbesondere mindestens einer der folgenden Pumpen: einer Vorwaschpumpe; einer Waschpumpe; einer Klarspülpumpe;
• – ein Start und/oder ein Stopp einer Frischwasserklarspülung;
• – ein Start und/oder ein Stopp eines Trocknungsgebläses.

In general, it is preferred if, according to the positioning, at least one of the following functions of the continuous dishwasher is activated and / or deactivated:

• - A start and / or stop at least one pump, in particular at least one of the following pumps: a Vorwaschpumpe; a washing pump; a rinse pump;
• A start and / or stop of a fresh water rinse;
• A start and / or stop of a drying blower.

All in all are the proposed pass-through dishwasher and the proposed method for cleaning of cleaning so extremely flexible with regard to the type of cleaning product. The cleaning can for the particular cleaning material or the Cleaning baskets can be optimally adjusted by the at least a parameter is optimally adapted to this type of cleaning material. The efficiency can thus be compared considerably increase conventional devices or methods. farther can save considerable amounts of energy, what in commercial dishwashing, especially in Continuous dishwashers, a significant savings potential of great economic value.

embodiments

Further Details and features of the invention will become apparent from the following Description of preferred embodiments in conjunction with the dependent claims. The embodiments are shown schematically in the figures. The invention is not limited to the embodiments.

It shows:

1 An embodiment of a continuous dishwasher according to the invention.

In 1 is a possible embodiment of a continuous dishwashing machine according to the invention 110 shown in a sectional view from the side. The pass-through dishwasher 110 is configured in this embodiment as a basket conveyor machine and has a transport device 112 for the transport of cleaning goods 111 on. The cleaning material 111 can be of various kinds and include, for example, pots, pans, containers, dinnerware, cutlery, glasses or the like. The cleaning material 111 is in baskets 113 , For example, plastic baskets used, which at a Aufgabestelle 114 on the transport device 112 be applied. From there they are transported in one direction 116 through the continuous dishwashing machine 110 transported to a take-off point 118 on the outlet side of the continuous dishwasher 110 be removed in a purified state again.

The transport device 112 which is for the transport of baskets 113 It does not necessarily have to be on the continuous dishwasher 110 be limited, but can, for example, even before the continuous dishwashing machine 110 begin and / or also over the end of the pass-through dishwasher 110 lead out. The sweeping dishwashing machine ne 110 Accordingly, it can be integrated into a larger cleaning system.

The used crockery baskets 113 can, as described above, for example, be made of plastic and may for example have a square or rectangular base. Typical dimensions are 500 mm × 500 mm. Depending on the application, different height side walls of about 100 mm to 300 mm may be provided, the latter, for example, for high glasses as cleaning 111 ,

The pass-through dishwasher 110 has in the illustrated embodiment, a plurality of cleaning zones, which successively from the cleaning material 111 to go through. Such is a pre-rinse zone 120 provided, with a pre-wash tank 122 and a pre-rinse system 124 , which has a pre-wash pump 126 from the pre-wash tank 122 is fed.

The pre-rinse zone 120 in the transport direction 116 downstream of this and optionally by a separation curtain 128 separated is a main wash zone 130 provided with a main rinse tank 132 and one via a main wash pump 136 from the main rinse tank 132 fed main wash system 134 ,

The main wash zone 130 is in turn, optionally again by a curtain 128 separated, a rinse zone 138 downstream, which is in a pump rinsing zone 140 and a fresh water rinsing zone 142 divided. The rinse zone 138 includes a common rinse tank 144 and a pump flushing system 146 the pump rinsing zone 140 as well as a freshwater rinsing system 148 the fresh water rinsing zone 142 , While the pump flushing system 146 over a rinse pump 150 with rinse liquid from the rinse tank 144 is fed, the freshwater rinse system 148 over a fresh water pipe 152 from a water inlet 154 fed.

The rinse zone 138 downstream of this and in turn by an optional separation curtain 128 separated is a drying zone 156 which, for example, via a blower 158 and an exhaust device 160 can dispose of. The fresh water pipe 152 For example, by the exhaust device 160 , For example, a heat exchanger of this exhaust device 160 , be guided and can continue a boiler 162 to bring the incoming water to a temperature required for the rinse.

It should be noted that the in 1 shown continuous dishwasher 110 merely by way of example, and that the continuous dishwashing machine can also be designed in a different way, for example only with a single cleaning zone. In particular, the continuous dishwashing machine 110 be varied with regard to the nature and design of the rinsing zones and the nature and design of the rinsing systems.

The baskets 113 the pass-through dishwasher 110 each have an electronic identifier in the illustrated embodiment 164 on. This electronic identifier 164 , where mutatis mutandis, several such identifiers 164 per crockery basket 113 can be provided, is contactless readable and example, designed as a transponder chip, which, for example, in the baskets 113 or at the baskets 113 can be appropriate. For example, these transponder chips can be replaced by a corresponding encapsulation or other encapsulation with respect to the ambient conditions in the continuous-type dishwashing machine 110 be protected or can also be completely in the baskets 113 be integrated, for example by molding with the material of the dish rack 113 ,

Furthermore, the continuous dishwasher in the illustrated embodiment has a plurality of readers 166 , These readers 166 For example, in a tunnel 168 the pass-through dishwasher 110 be arranged and are in 1 only symbolically indicated. As readers 166 For example, commercially available transponder chip readers may be used, which may be of the electronic identifier type 164 can be adjusted.

It is in the in 1 illustrated embodiment of the pre-rinse zone 120 , the main flushing zone 130 , the rinse-off zone 138 and the drying zone 156 each with its own reader 166 assigned. Other embodiments are possible, for example with a higher number of readers 166 or a smaller number of readers 166 for example by grouping together several zones.

The readers 166 are exemplary in the illustrated embodiment on the ceiling of the tunnel 168 arranged. Since conventional tweeter technologies have only a very limited range of, for example, 50 cm to 1.5 m, the readers are 166 Thus, at the same time usable as position detecting devices and are adapted to at least approximately a position of a dish rack 113 to determine. For example, the signals of several readers 166 be evaluated, taking from the signal strength of each reader 166 For example, by means of a triangulation method, exactly on the positioning of the dish rack 113 can be closed as the dish rack 113 on the transport device 112 can move only one-dimensional and because, for example, the signal strength as a function of the distance between the electronic identifier 164 and reader 166 can be known.

The contactless readable electronic identifier 164 transmits at least one piece of information to the reader 166 , for example, as a result of a polling pulse of this reader 166 , For example, any reader 166 at regular or irregular intervals or continuously send such a polling pulse to ask if there is an electronic identifier 164 within range of the respective reader 166 located. If this is the case, then this electronic identifier 164 be configured to a corresponding response pulse, comprising the at least one information, to the questioning reader 166 to send. This at least one identification can, for example, information about the type of dish rack 113 (and thus implicitly, for example, about the type of cleaning product 111 especially if different crockery baskets 113 for different types of items to be cleaned 111 may be used), a serial number, information on a degree of pollution, information on the nature of the pollution or the like.

The readers 166 These can be at least one piece of information, for example, to a controller 170 the pass-through dishwasher 110 convey which in 1 is shown only symbolically. This control 170 For example, a central control of the continuous dishwasher 110 which may be arranged to pass programs of the dishwasher 110 to control. For this purpose, the controller 170 For example, all or some of the machine functions of the continuous dishwasher may be set up 110 centrally or decentrally to control, regulate or control in general and turn on after a respective wash program corresponding scheme or timing, shut down or adjust accordingly.

This wash program can now provide the at least one piece of information from the readers 166 is transmitted, process and set at least one parameter of the wash program accordingly. In the simplest case, this at least one piece of information can be a simple presence information of a dish rack 113 include, so the information that a particular dish rack 113 in the range of a particular reader 166 is. This again corresponds to the position detection described above. Accordingly, the at least one parameter may also include a parameter of a time sequence, so that, for example, the individual cleaning zones 120 . 130 . 138 (respectively. 140 . 142 ) as well as the drying zone 156 can be switched accordingly, as soon as a dish rack 113 within reach of these zones. In this way, for example, avoid unnecessary operation of the individual zones, which can save energy and cleaning fluid. An automatic detection of the baskets 113 can be used, for example, to the economic operation of the continuous dishwasher 110 to increase. So can one on the transport route of the transport device 112 promoted crockery basket 113 via the carcass recognition device by means of the readers 166 the pass-through dishwasher 110 put into operation at the right time and put back into a pause state, for example, after passing through the conveyor dishwasher. Also, by means of the basket detection certain functions within the continuous dishwasher 110 enable or disable. These functions include, for example, a start and a stop of the pumps 126 . 136 or 150 a start of the fresh water rinse, a start of the blower drying in the drying zone 156 (where mutatis mutandis, several such blower 158 or drying zones 156 may be provided) or the like.

Since the at least one piece of information of the electronic identifier 164 For example, information about the type of cleaning 111 may also include, for example, difficult to clean cleaning supplies 111 automatically parameters of cleaning can be optimized, allowing automatic adjustment of the parameters individually on this cleaning material 111 can be done. Thus, for example, in particularly difficult to clean cleaning products 111 a reduction in the transport speed of the transport device 112 an increase in pump performance, an increase in tank temperatures, an increase in detergent dosage, a connection of special intensive treatment by chemicals or chemical additives or the like. The parameters for an optimal washing result and also for the economy of the continuous dishwasher 110 depend very much on the type of laundry. By marking the baskets 113 with the electronic identifier 164 , For example, a corresponding coded microchip, can in many ways the machine parameters to the respective items to be cleaned 111 be adjusted. As a result, for example, the possibilities of incorrect operation, for example by a manual program selection on the controller 170 , almost impossible.

Furthermore, the controller 170 a do kumentationsvorrichtung 172 include, or such a documentation device 172 Can be used as a separate device in the continuous dishwashing machine 110 be provided. This documentation device 172 For example, one or more of the at least one transmitted information of the electronic identifier 164 to save. In this way can be, through the use of marked baskets 113 For example, you can easily and very easily record and save the machine settings (parameters) and presets. The documentation of certain machine parameters, for example, in hygiene-critical areas, such as the care of the elderly or in clinics or similar institutions, partly already prescribed.

By means of the illustrated continuous dishwasher 110 can also be easily counted crockery baskets. For example, for this purpose, the controller 170 the function of a basket counter 174 take over, or it can separately such a basket counter 174 be provided. Such a basket count may be required, for example, in the preparation of profitability calculations for the continuous dishwasher 110 , The illustrated basket count is characterized by the readers 166 and the electronic identifiers 164 very flexible with regard to the technical versions of the baskets 113 and is not limited to, for example, a particular basket type of baskets 113 ,

Finally, it should be noted that instead of in 1 illustrated continuous dishwasher 110 the idea of the invention, ie the use of electronically readable identifiers 164 and readers 166 and the corresponding device of the machine for selecting the at least one parameter of a washing program, in principle, could also be used in other types of cleaning devices. Thus, such a detection of information of the identifiers, for example, in principle, in program machines or in cleaning and disinfection equipment can be used, for example, to program parameters, such as cleaner dosages to adapt. In the mentioned continuous dishwashing machines 110 the embodiment of the invention, however, is particularly advantageous because here an intelligent management of the handling of baskets 113 is required.
