Description
The application is a divisional application of an invention patent application with the application date of 2009, 3 and 4, international application number of PCT/US2009/035950, national application number of 200980109371.0 and the invention name of "conveyor dishwasher and use method thereof".
Technical Field
The invention relates to a conveyor dishwasher and a method for using the same.
The invention relates in particular to a long-dragon dishwasher (ware washing machine) or a dish rack channel conveying dishwasher (ware washing machine).
Background
Conveyor dishwashers (warewashers) have been commercialized. When the household dish washer is used for washing the washing piece, the washing piece needs to be kept still; in contrast, when the conveyor dishwasher washes the washware, the washware is conveyed between the different treatment zones of the conveyor dishwasher.
In conveyor dishwashers, washing articles such as dishes, pots, cups, cutlery and other items to be washed are conveyed through several treatment zones, such as a pre-wash zone, a main wash zone, a post-wash or pre-rinse zone, a final rinse zone and a drying zone. However, different types of cleaning elements require different treatment parameters to be set in each treatment process due to different final use conditions, different oil contamination degrees, different shapes and different materials. Conveyor dishwashers currently in use are generally not capable of automatically distinguishing the type of wash ware; as a compromise, conventional systems are often designed to accommodate cleaning of a variety of different types of items.
The patent No. US 6530996B2 describes a rack aisle conveyor dishwasher, to which the items to be cleaned, which have been pre-sorted and have been placed on the racks, are conveyed to the various treatment zones of the rack aisle conveyor dishwasher. Conventional conveyor dishwashers provide sensors which determine the type of items to be washed by detecting identification features provided on the dish racks. Based on these detected identification features, an appropriate (dish) washing program is then selected for the conveyor dishwasher.
DE 19608030C 1 discloses another conveyor dishwasher, in which, depending on the type and degree of soiling of the items to be cleaned in the individual treatment zones of the conveyor dishwasher, additional spraying systems are activated or deactivated in order to change the spacing between the treatment zones of the items to be cleaned.
In the conveyor dishwasher patent No. DE 102005021101 a1, it is known that additional nozzles can be activated or deactivated depending on the conveying speed of the wash ware in the washing zone of the conveyor dishwasher in order to reduce the water consumption in the final rinse phase. A sensor for detecting the dishes is arranged at the inlet of the conveyor dishwasher, and the system automatically reduces the conveying speed when the number of washing parts entering the conveyor dishwasher decreases.
Disclosure of Invention
The invention is based on the object of providing a conveyor dishwasher comprising at least one washing zone, at least one final rinsing zone and a control device which, in addition to reducing the consumption of resources (clean water, chemicals and energy) during operation, allows good treatment of all types of washing stock. The invention will also describe a corresponding method for operating such a conveyor dishwasher.
On one hand, after the cleaning piece detector is installed, the type of the piece to be cleaned can be automatically detected. In a further aspect, an optimized treatment program can be automatically selected in at least one treatment zone of the conveyor dishwasher for each washing means that has been detected, and treatment parameters can be set in relation to the selected treatment program. By optimally adjusting the treatment parameters associated with the respective treatment zones, the consumption of clean water, chemicals and energy can be reduced.
In order to achieve an optimum adjustment of each program sequence in the treatment zone of the conveyor dishwasher in dependence on the detected type of wash ware, a predefined or settable wash ware grouping for the various types of wash ware in the treatment zone of the conveyor dishwasher is determined by the control device. Furthermore, for each wash-ware group there is a predefined treatment program according to which wash ware of the type belonging to this group is treated in at least one of the treatment zones of the conveyor dishwasher, for example a pre-wash zone, a main wash zone, a post-wash or pre-rinse zone, a final rinse zone and/or a drying zone.
The pre-set treatment program for each cleaning element group is preferably adjusted to the most economical optimization treatment program. Accordingly, the invention makes it possible to optimize and adjust automatically the treatment parameters of the conveyor dishwasher in accordance with the type of the various items to be treated.
Therefore, the invention can automatically distinguish the types of the cleaning pieces to be processed, and adjust the processing parameters of each processing step in the cleaning process so as to adapt to the cleaning piece group appointed for the types of the cleaning pieces to be cleaned.
By "type of cleaning element" is understood here the type of cleaning element to be treated and/or cleaned. The type of cleaning element depends, inter alia, on the characteristics of the cleaning element to be cleaned, such as size, shape and/or material.
According to a preferred embodiment of the solution according to the invention, at least the following cleaning elements are detected with regard to the type detection of the cleaning elements:
-a plate of porcelain or porcelain-like material;
-cups of ceramic or ceramic-like, glass or glass-like material;
-a bowl of porcelain or porcelain-like, glass or glass-like material;
-a pallet or pallet-like item made of plastic;
-containers made of metal, in particular stainless steel, in particular of the GN type;
-a pan made of metal, in particular stainless steel;
-pans made of metal, in particular stainless steel;
-cutlery or cutlery-like articles made of metal, in particular stainless steel; and
a drinking cup of glass or similar glass material.
The present invention is based on the following findings: the process parameters selected for effective treatment and/or cleaning in the individual treatment zones depend on the type of piece to be cleaned. When different types of washing parts are to be treated, for example in the washing zone (pre-washing zone, main washing zone, post-treatment zone) of a conveyor dishwasher, a suitable treatment program needs to be selected. In particular, the treatment program is adjusted with regard to the volume flow of rinsing liquid sprayed per unit time in at least one of the rinsing zones and the rinsing liquid spray pressure in at least one of the rinsing zones. For example, relatively greasy dishes, such as trays or drinking glasses, need only to be sprayed with a relatively small flow of cleaning liquid per unit time and a relatively low spraying pressure in the washing zone; but not heavy greasy tableware such as burnt food and food residue which is difficult to remove.
On the other hand, different types of washing parts require different treatment programs, which should be adjusted with regard to the final-rinse liquid spray rate per unit time in the final-rinse zone, according to which the treatment of the washing parts in the final-rinse zone of the conveyor dishwasher needs to be carried out.
The solution according to the invention can be implemented: the cleaning regime of at least one of the cleaning zones (i.e. the cleaning fluid spray rate per unit time of the cleaning zone, and the cleaning fluid spray head pressure of the cleaning zone) can be optimally adjusted to the type of cleaning elements to be treated in the cleaning zone.
According to an alternative or additional solution of the invention, it is also possible to implement: for example, the spray rate of final-rinse liquid per unit time in the final-rinse zone can be optimally adjusted to the type of cleaning elements to be treated in the final-rinse zone.
Therefore, the 'over-cleaning' of the tableware with light oil stains, such as trays or drinking glasses, can be avoided in a direct and effective mode, and the unnecessary waste of energy, water and chemicals is avoided in the process of cleaning the tableware with light oil stains.
Thus, a reduction in the clean water consumption of the washing elements can be achieved, for example, in the final-rinse zone, or in the amount used in combination with other additives. The reduction in the clean water consumption of the conveyor dishwasher means that the amount of chemicals used, in particular rinsing and/or cleaning agents, can likewise be reduced without the chemical concentration of the various liquid formulations being affected. The reduced supply of purified water also means that the amount of water that needs to be heated is reduced, and therefore the purpose of energy saving can be achieved.
The object of the invention is further achieved with a method of operating a conveyor dishwasher having at least one washing zone, at least one final-rinse zone and a control device. The invention determines that the implementation steps of the operation method are as follows. First, the type of cleaning element to be treated is to be detected. Then, a preset or settable processing program is automatically selected for each cleaning article group, the cleaning article type assigned to the cleaning article group is to be processed in at least one cleaning zone in accordance with the processing program, and processing parameters associated with the processing program are set. As an alternative or in addition to the last-mentioned implementation step, a preset or settable treatment program is automatically selected for each wash ware group, the wash ware type assigned to the wash ware group is to be treated in accordance with this treatment program in at least one final rinsing zone, and treatment parameters associated with this treatment program are set.
The invention will now be described, by way of example, with reference to the accompanying drawings and using preferred embodiments.
Drawings
In the drawings:
FIG. 1 shows a longitudinal section through a conveyor dishwasher according to a first embodiment; and
fig. 2 shows a longitudinal section of a conveyor dishwasher according to a second embodiment.
Detailed Description
Fig. 1 shows a conveyor dishwasher 1 with a conveyor device 2, by means of which washing parts (not shown in the drawing) are conveyed through the conveyor dishwasher 1 in a conveying direction 3. The conveyor means 2 can be, for example, a conveyor belt which is preferably designed as a multi-component plastic conveyor belt and is preferably continuously driven by an electric motor (not shown in fig. 1), the cleaning elements placed on the conveyor belt 2 being conveyed in succession through the different treatment zones 6, 7, 8, 9, 10 and 26 of the conveyor dishwasher 1, as shown in fig. 1. The cleaning elements conveyed in the conveying direction 3 are usually placed on the conveyor or conveyor belt 2 in the region of the inlet 4. The cleaning elements are then transported from the inlet 4 in a transport direction 3 to the inlet channel 5, which transport direction 3 is indicated by an arrow in the figure.
The conveyor dishwasher 1 shown in fig. 1 has at least one washing zone, which, for example, as shown in fig. 1, can be a pre-washing zone 6, a first main-washing zone 7 or a second main-washing zone 8, which, viewed in the conveying direction 3, are arranged downstream of the pre-washing zone 6.
According to the conveyor dishwasher 1 shown in fig. 1, following at least one washing zone 6, 7, 8, in the conveying direction 3, is a post-wash treatment zone 9 and a final-rinse zone 10, the final-rinse zone 10 being located downstream of the post-wash treatment zone 9.
The conveyor 2 shown in fig. 1 is an endless conveyor belt. However, a rack into which a cleaning material (not shown) is inserted and which is placed on the upper side of the conveyor belt may be used as the conveyor 2.
Viewed in the conveying direction 3, the cleaning elements placed directly on the conveyor belt 2 or on a conveyor rack pass in the conveying direction 3 through the inlet channel 5, the subsequent pre-cleaning zone 6, the first main cleaning zone 7, the second main cleaning zone 8, the post-treatment zone 9, the final-rinse zone 10 and the drying zone 26 in succession, into the outlet zone 25.
The above-mentioned treatment zones 6, 7, 8, 9 and 10 of the conveyor dishwasher 1 are provided with spray heads 11, 12, 13, 14 and 15, respectively, through which liquid is sprayed onto the washing parts conveyed by the conveyor 2 through the treatment zones 6, 7, 8, 9 and 10, respectively. Each treatment zone 6, 7, 8, 9 and 10 is provided with a tank 16, 18, 20 and 22, respectively, which contains a spray liquid and/or supplies a liquid for the spray heads of the relevant zone. In the conveyor dishwasher 1 shown in fig. 1, final-rinse liquor in the form of clean water, which can be pure water or a mixture of water and further additives, which can be rinsing agents for example, is sprayed onto the washing elements (not shown in the drawing) via spray heads 15 of the final-rinse zone 10, which can be arranged on both sides, above and below the conveyor belt.
Part of the sprayed final rinse liquid is conveyed from one zone to the other zone through a cascade system in the opposite direction to the conveying direction 3 of the washing elements. The remainder is directed via valve 77 and bypass line 88 to prewash tank 16.
The sprayed final rinse liquid is collected in the water tank 20 (post-wash water tank 20) in the post-wash treatment zone 9, and is thereby delivered to the spray heads 14 (post-wash spray heads 14) of the post-wash treatment zone by the water pump device. In the post-wash treatment zone 9, the washing liquid is washed off the washing elements. The liquid accumulated in this area flows into the wash water tank 18b of the second main wash zone 8, and this liquid is usually sprayed onto the wash ware by the spray head 13 (wash spray head 13) of the second main wash zone 18 after the addition of the wash agent by means of a water pump. The liquid flows from the water tank 18b of the second main washing zone 8 into the washing tank 18a of the first main washing zone 7. Here, the liquid is sprayed again by the washing nozzles 12 of the first main washing zone 7 onto the washing elements by means of the water pump device. The liquid flows from the tank 18a of the first main washing zone 7 into the pre-wash tank 16 of the pre-washing zone 6. The liquid in the pre-wash tank 16 is sprayed by means of a water pump from the pre-wash nozzles 11 in the pre-wash zone 6 onto the wash ware in order to remove larger oil stains from the wash ware.
The separate cleaning systems of the treatment zones 6, 7, 8, 9 and 10 ensure that spray cleaning can be carried out simultaneously from the upper side to the lower side of the cleaning elements.
The individual washing zones 6, 7, 8, 9 and 10 of the conveyor dishwasher can be separated by a partition 37. In the embodiment shown in fig. 1, the inlet channel 5 itself is separated from the inlet 4 by a partition 37. The partition 37 prevents the washing liquid and the final rinse liquid from being sprayed onto the separated areas and prevents moisture from escaping the conveyor dishwasher.
After the final-rinse zone 10, viewed in the transport direction 3 of the washing parts, is located the drying zone 26 already mentioned. In the drying zone 26, the cleaning elements are dried using dry, heated air in order to blow off and dry moisture located on the cleaning elements. In order to keep the moisture content of the air within a range that is favorable for drying of the cleaning elements, it is possible, for example, to supply ambient air through an opening, for example through an outlet of the cleaning elements. Hot air containing water is discharged from the drying zone 26 through another opening, for example, possibly by means of a fan 31. It is further advantageous if here the exhaust gases of the drying zone 26 pass through a heat recovery device 30, which may be provided with a compressor. The heat recovery device 30 is used to recover at least part of the heat energy in the exhaust gas.
In current longmen/dish rack tunnel conveyor dishwashers, the wash ware is conveyed through several treatment zones, for example a pre-wash zone, a main wash zone, a post-wash treatment zone, a final rinse zone and a drying zone. As already mentioned, different types of washing parts in conveyor dishwashers require different treatment parameters. However, the conveyor dishwashers known at present do not automatically distinguish between the types of washing ware to be treated, in which case conventional systems are often designed with a compromise in order to be suitable for a plurality of types of washing ware, with either high or low efficiency. This means that: a greater consumption of significant, unnecessary resources (energy, water, chemicals, etc.) is typically required to dispose of the cleaning elements than is actually required.
As shown for example in fig. 1, a conveyor dishwasher 1 made in accordance with the invention is characterized in that a wash ware detector 34 is provided for detecting the type of wash ware to be treated in the conveyor dishwasher 1. The term "wash ware detector" as used herein may refer to any detector designed to detect and/or determine the type of wash ware to be treated in the conveyor dishwasher 1. In this case, in particular the wash-ware detector 34, is equipped with at least one detection device 35 which can detect the size, shape and/or material of the wash ware to be treated in the conveyor dishwasher 1.
In a preferred embodiment of the conveyor dishwasher 1 made according to the invention, the wash-ware detector 34 has at least one preferably optical, inductively or capacitively operated detection device 35, the type of wash ware being determinable by direct detection of the size, shape and/or material of the wash ware. However, it is also possible that the detection means 35 is constituted by other types of detectors, such as inductively operated proximity sensors, optical sensors, light curtains, laser scanners, 3D lasers, cameras, rotary sensors, etc.
A wash ware detector 34 is preferably mounted at the inlet 4 of the conveyor dishwasher 1 in order to detect the type of wash ware to be fed into the respective treatment zones 6, 7, 8, 9, 10 and 26 of the conveyor dishwasher 1. Of course, the wash item detector 34 can also be mounted in a suitable manner in the interior of the conveyor dishwasher 1.
The conveyor dishwasher 1 made according to the invention can also have a control device 36 as illustrated in fig. 1. The control device 36 is designed to trigger the individual triggerable components of the conveyor dishwasher 1, such as the individual water pumps and valves, according to a preset or settable program sequence, in order to allow the setting of the appropriate treatment parameters for the individual treatment zones 6, 7, 8, 9, 10 and 26 of the conveyor dishwasher 1.
As shown, the control device 36 is connected to the wash-ware detector 34 via a suitable communication link in order to query continuously or on a predetermined time basis and/or upon the occurrence of a predetermined event for the type of wash ware which is fed into the conveyor dishwasher 1 and is detected by the wash-ware detector 34.
The control device 36 is designed to function in order to automatically detect the cleaning elements to be treated on the basis of the type of cleaning element detected by the cleaning element detector 34. The control device 36 can preferably automatically detect at least the following cleaning elements:
-a plate of porcelain or porcelain-like material;
-cups of ceramic or ceramic-like, glass or glass-like material;
-a bowl of porcelain or porcelain-like, glass or glass-like material;
-a pallet or pallet-like item made of plastic;
-containers made of metal, in particular stainless steel, in particular of the GN type;
-a pan made of metal, in particular stainless steel;
-pans made of metal, in particular stainless steel;
-cutlery or cutlery-like articles made of metal, in particular stainless steel; and
a drinking cup of glass or similar glass material.
The washing members associated with the detected washing member type, which cannot be ascertained by the control device 36, are classified as "other types of washing members".
The solution provided by the invention is advantageous not only in that the type of cleaning elements can be detected automatically and the cleaning elements to be treated can be detected automatically, but also in that the control device 36 has an additional function, on the basis of which the latter can assign a predetermined or settable cleaning element group to each type of cleaning element detected.
This assignment capability ensures that the different types of wash ware which can be treated in the individual treatment zones 6, 7, 8, 9, 10 and 26 in the conveyor dishwasher 1 according to the same treatment parameters can be grouped together. Here we find that: in order to subject dishes made of porcelain or porcelain-like material and cups and bowls made of porcelain or porcelain-like material, glass or glass-like material to the pre-washing, main-washing, final-rinsing and drying procedures in the treatment zones 6, 7, 8, 9, 10 and 26, the same or substantially the same parameter settings can be selected to optimize these types of cleaning elements while making the best use of resources.
In contrast, when treating trays made of plastic or tray-like articles, the pre-wash stage can be skipped altogether and the flow of final rinse solution sprayed in the final-rinse zone 10 units of time can be reduced compared to treating dishes, cups or bowls.
In contrast, when treating containers made of metal, in particular stainless steel, in particular GN-type containers, pots and pans, the quantity of cleaning liquid sprayed per unit time in the washing zones 6, 7, 8 of the conveyor dishwasher 1 and the pressure of the cleaning liquid spray heads in the washing zones 6, 7, 8 should be increased in order to achieve a better cleaning result than in the case of other types of cleaning elements. Furthermore, the transport speed of these types of washing elements through the treatment zones 6, 7, 8, 9, 10 and 26 of the conveyor dishwasher 1 can be slowed down in the treatment of containers, pots and pans, in order to prolong the individual treatment times in the individual treatment zones. This in turn makes it possible to set the value of the final-rinse flow sprayed per unit of time in the final-rinse zone 10 of the conveyor dishwasher 1 to a relatively low level.
In the treatment of cutlery or cutlery-like items made of metal, in particular stainless steel, in the pre-wash zone 6 and the main wash zone 7, 8 of the conveyor dishwasher 1, preferably the same or similar treatment parameters as those used for the treatment of dishes, cups or bowls are required.
However, the type of wash ware to which the cutlery and cutlery-like items belong preferably requires an increased flow rate of final rinse liquid per unit time compared to the treatment of dishes, cups or bowls in the final rinse zone 10 of the conveyor dishwasher 1.
If the wash item detector 34 detects a drinking glass made of glass or the like, the treatment of such wash items may completely skip the pre-wash program phase of the pre-wash zone, since if not, such wash items may be contaminated or adversely affected by the wash liquid already sprayed in the pre-wash zone 6, which is usually already greasy. Nevertheless, for the treatment of such washing elements (drinking glasses), only one of the two main washing zones 7, 8 shown in fig. 1 needs to be opened.
In order to prevent recontamination of such washing parts (drinking glasses) in the post-wash treatment zone 9 of the conveyor dishwasher 1, the following measures should be taken: in order to treat such cleaning elements, the post-wash treatment zone 9 is closed, for example, to prevent post-wash rinsing liquid from entering the post-wash treatment zone 9. The lack of a pump flush in the post-wash treatment zone 9 can be counteracted by increasing the clean water flush in the final-rinse zone 10, for example by increasing the final-rinse flow sprayed per unit time in the final-rinse zone 10.
In order to be able to select the optimum process parameters for the different types of cleaning elements, the following grouping designations can preferably be made with the aid of the control device 36:
-a plate made of porcelain or porcelain-like material, cups and bowls made of porcelain or porcelain-like material, glass or glass-like material being assigned to a first washing member group;
containers made of metal, in particular stainless steel, in particular GN-type containers, pots and pans are designated as a second wash ware group;
-a plastic tray or tray-like article is assigned a third wash-ware group;
-drinking glasses made of glass or similar glass are assigned a fourth washing-element group; and
the cutlery and cutlery items made of metal, in particular stainless steel, are assigned to a fifth cleaning element group.
The above-mentioned cleaning member components have been previously defined. However, if desired, the operator of the conveyor dishwasher 1 can of course also make changes to the wash-ware grouping.
The solution provided by the invention has the advantages that: the control device 36 is designed to automatically select a set-up process program (preset or later set by the user) for each cleaning agent group, to process the cleaning agent types assigned to the cleaning agent groups in the pre-cleaning zone 6, the main cleaning zones 7, 8 and/or the post-cleaning treatment zone 9 according to the set-up process program, and to set up process parameters associated with the selected process program. As an alternative or in addition to this, the control device 36 can also automatically select a preset or settable treatment program for each wash ware group, specify the type of wash ware of the wash ware group to be treated in the final-rinse zone 10 according to the treatment program, and set the treatment parameters associated with the selected treatment program.
For this purpose, the control device 36 can be equipped, for example, with a memory device (for example a memory — not shown in fig. 1) which is accessible to the control device 36 and on which an optimally adjusted processing program and the corresponding processing parameters for the operation of the respective processing zone 6, 7, 8, 9, 10 and 26 are stored for the respective cleaning-component group concerned.
The preferred embodiment of a conveyor dishwasher 1 as shown in fig. 1 made in accordance with the invention determines explicitly: when the control device 36 detects that the cleaning elements belong to the first, third, fourth or fifth cleaning element group, the flow of cleaning liquid sprayed per unit time in the two main cleaning zones 7, 8 is automatically set to a preset average value, for example 600 l/min. Furthermore, for the treatment of the cleaning elements, the pressure of the spray heads spraying cleaning liquid in the two main cleaning zones 7, 8 is preferably set to a predetermined average value, for example 0.2 to 0.4 bar.
On the other hand, the preferred embodiment of the conveyor dishwasher 1 determines: the control device 36 detects that the cleaning elements belong to the second cleaning element group and automatically sets the flow rate of cleaning liquid sprayed per unit time in the two main cleaning zones 7, 8 to a preset high value, for example greater than 650 l/min. The pressure of the spray heads spraying the cleaning liquid in the two main cleaning zones 7, 8 should likewise be adjusted to a predetermined high value, here greater than 0.4 bar.
With regard to the treatment of the washing members in the final rinse zone 10, a preferred embodiment of the control device 36 determines: when the control device 36 detects that the wash ware belongs to the first wash ware group, the flow rate of final rinse liquid sprayed per unit time in the final rinse zone 10 is automatically set to a preset average value, for example 170 to 200 l/h. In contrast, when the control device 36 detects that the wash ware belongs to the second or third wash ware group, the flow rate of final rinse liquid sprayed per unit time in the final rinse zone 10 is preferably automatically set to a preset low value, for example below 170 l/h. In contrast, when the control device 36 detects that the wash ware belongs to the fourth or fifth wash ware group, the flow rate of final rinse liquid sprayed per unit time in the final rinse zone 10 is automatically set to a preset high value, for example to a value higher than 200 l/h.
The values mentioned above are only examples and are not actually limited to these values.
In principle, in the conveyor dishwasher 1 shown in fig. 1, the conveying speed of the washware to be treated through the treatment zones 6, 7, 8, 9, 10 and 26 of the conveyor dishwasher 1 can be selected and set automatically in accordance with the specified washware group, in order to adjust the treatment times in the respective treatment zones 6, 7, 8, 9, 10 and 26 in accordance with the type of washware to be treated. When the control device 36 detects that the cleaning elements belong to the second cleaning element group, it is preferred that the control device automatically sets the conveying speed to be lower than when the cleaning elements are detected as belonging to the first, fourth or fifth cleaning element group.
Fig. 2 shows a schematic side view of a second embodiment of a conveyor dishwasher according to the invention. The conveyor dishwasher 1 shown in fig. 2 differs from the embodiment described previously with reference to fig. 1 in that: in a second embodiment, only one main wash zone is provided. The rest of the conveyor dishwasher 1 according to fig. 2 is constructed identically to the conveyor dishwasher according to fig. 1, so that reference can be made here to the description relating to fig. 1.
The invention is not limited to only the two embodiments of fig. 1 and 2 in the drawing examples. Rather, the invention results from a combination of the patent claims and a comprehensive and technical insight into the description of the exemplary embodiments.
In particular, for example, the conveyor dishwasher 1 according to the invention can also be equipped with a steaming zone (not shown in the drawing), the control device 36 automatically providing a set value for each wash ware group for determining the steam supply to the steaming zone to be switched on or off, preferably automatically switching on the steam supply to the steaming zone when wash ware belonging to the second wash ware group is detected.
In principle, the conveyor dishwasher 1 according to the invention can also be equipped with a direct-action detergent spray system, and the control device 36 can automatically provide a setpoint value for each wash ware group for determining the opening or closing of the detergent supply of the direct-action detergent spray system or for controlling the quantity of detergent to be used in accordance with the wash ware group.
The control device 36 can also be realized to automatically select a preset or settable treatment program for each washing-ware group, to which treatment program the type of washing ware assigned to the washing-ware group is to be treated in the drying zone 26, and to set treatment parameters associated with the selected treatment program.
In principle, it is preferred that the control device 36 selectively automatically selects and accordingly sets the treatment parameters which enable an optimum treatment of the various types of washing elements, so that in principle the user of the conveyor dishwasher can also manually set or change the treatment parameters to be carried out in the individual treatment zones.
