Description

[0001] The present invention relates generally to the field of commercial dishwashing and, more particularly, to a dishwasher according to the preamble of independent claim 1.

[0002] Accordingly, the invention relates in particular to a dishwasher for cleaning items to be washed in the form of drinking vessels, in particular in the form of drinking cups, cups, glasses or bottles, wherein the dishwasher has at least one treatment zone and preferably exactly one treatment zone and preferably at least one transport device for transporting the items to be cleaned from a setting area of ​​the dishwasher through the at least one treatment zone of the dishwasher to a removal area of ​​the dishwasher.

[0003] The setting area of ​​the dishwasher is, in particular, the dirty-side input area, which is designed so that the dishes to be cleaned in the at least one treatment zone of the dishwasher can be manually inserted there. On the other hand, the removal area of ​​the dishwasher is, in particular, the clean-side output area, which is designed to dispense the dishes cleaned in the at least one treatment zone of the dishwasher so that they can then be manually removed.

[0004] The dishwasher according to the invention further comprises, in particular, a washing and / or rinsing system with at least one washing and / or rinsing pump and with washing and / or rinsing nozzles, via which cleaning liquid, in particular washing and / or rinsing liquid, can be sprayed onto the items to be cleaned in the at least one treatment zone of the dishwasher.

[0005] Dishwashers of the aforementioned type, and in particular dishwashers with a transport device for transporting the items to be cleaned through at least one treatment zone of the dishwasher, are typically used in commercial applications. Unlike household dishwashers, in which the items to be cleaned remain stationary in the dishwasher during cleaning, such conveyor dishwashers transport the items to be cleaned through various treatment zones of the machine.

[0006] Such a conveyor dishwasher is known, for example, from document DE 19 644 438 A1. This conveyor dishwasher comprises, in sequence in the direction of transport of the washware, a pre-cleaning zone with pre-cleaning nozzles for removing coarse soiling from the washware, at least one wash zone with wash nozzles for spraying wash liquid onto the washware, a pre-wash zone with pre-wash nozzles, and a fresh water rinse zone with rinse nozzles. The rinse nozzles spray rinse liquid, in particular fresh water, onto the washware. The sprayed rinse liquid enters a pre-wash tank, from which it is pumped to the pre-wash nozzles via a pump line. The pre-wash liquid sprayed by the pre-wash nozzles flows back into the pre-wash tank. Part of the pre-wash liquid sprayed by the pre-wash nozzles is directed through a deflector into the wash tank of the last wash zone.A liquid cascade system allows liquid to flow against the direction of the washware transport from the pre-wash tank into the last wash tank and from there on to a tank which collects the liquid sprayed by the pre-cleaning nozzles in the pre-cleaning zone.

[0007] Because conveyor dishwashers transport the wash ware through various treatment zones (particularly wash zones and final rinse zones), continuous operation is possible – unlike the batch processes of stationary programmable dishwashers, such as household dishwashers or undercounter dishwashers. The disadvantage of conveyor dishwashers, however, is the relatively large space required in the installation room (laundry room).

[0008] However, there is an increasing need to utilize the advantages of a conveyor dishwasher in applications where only a small installation space is available.

[0009] Nowadays, hotels, company canteens, public buildings, hospitals, schools, and rest stops almost always have self-service hot drink vending machines, especially coffee machines, of various models and sizes. These hot drink vending machines are typically designed to fill cups with a selected hot beverage, although plastic cups are also used in vending machine installations in companies or public buildings.

[0010] On the other hand, the use of plastic cups is increasingly decreasing due to ecological aspects, in favor of reusable tableware (glasses, cups, etc.).

[0011] To clean cups, glasses, etc. (hereinafter also referred to as "drinking vessels") after use, a standard commercial dishwasher is typically used. For this purpose, the dirty items are collected, transported to the dishwasher (which is usually not located directly near the hot drinks machine), cleaned there, and then returned to the hot drinks station or hot drinks machine.

[0012] Accordingly, a change in hot beverage vending machines from disposable to reusable tableware poses problems with regard to the logistics required, particularly in the form of workers to carry out the individual process steps, such as collecting the soiled, reusable tableware, filling a dishwasher usually provided externally, and returning the cleaned tableware to the hot beverage vending machine.

[0013] It is not possible to install a conventional conveyor dishwasher known from the prior art in the immediate vicinity of a hot drinks vending machine, since such conveyor dishwashers require a relatively large amount of space in the installation room, which is generally not found near hot drinks vending machines.

[0014] The document DE 27 27 067 A1 relates to a device for cleaning open vessels, such as glasses, jugs or the like, by means of liquid jets, in that the vessels are transported with the opening downwards on a transport device through a cleaning zone.

[0015] The invention is based on the object of developing a dishwasher of the type mentioned at the outset in such a way that it has a particularly compact design so that the dishwasher can also be used in applications in which conventional conveyor dishwashers cannot be used due to a lack of available installation space.

[0016] This object is achieved by the subject matter of independent patent claim 1, wherein advantageous developments of the dishwasher according to the invention are specified in the dependent patent claims.

[0017] Accordingly, the invention relates to a dishwasher for cleaning items to be cleaned in the form of drinking vessels, wherein the dishwasher has at least one treatment zone and preferably at least one transport device for transporting the items to be cleaned from a setting area of ​​the dishwasher through the at least one treatment zone of the dishwasher to a removal area of ​​the dishwasher. The dishwasher according to the invention further comprises a washing and / or rinsing system with at least one washing and / or rinsing pump and washing and / or rinsing nozzles, via which cleaning liquid, in particular washing and / or rinsing liquid, can be sprayed onto the items to be cleaned in the at least one treatment zone.

[0018] According to the invention, it is provided that the dishwasher is spatially divided into an over-counter area, which is located above a counter level when the dishwasher is in its intended use, and an under-counter area, which is located below the counter level when the dishwasher is in its intended use, wherein the setting area, the removal area and the at least one treatment zone of the dishwasher are each part of the over-counter area, and wherein at least the at least one washing and / or rinsing pump of the washing and / or rinsing system is part of the under-counter area.

[0019] The advantages that can be achieved with the dishwasher according to the invention are obvious: the dishwasher according to the invention allows the items to be washed individually as desired, so that the dishwasher is particularly suitable for cleaning reusable drinking vessels, such as coffee cups, wherein the dishwasher can be installed directly at a drinks machine, in particular hot drinks machines, or in the immediate vicinity of a drinks machine, in particular hot drinks machines.

[0020] Currently, beverage vending machines, especially hot beverage vending machines, are usually equipped with a device for dispensing disposable containers, which become waste after use or are subject to mandatory take-back following the entry into force of legal provisions.

[0021] There are also vending machines that don't provide or dispense containers, so users use their own cups or similar items, which they then clean themselves after use. This results in unnecessary freshwater consumption unless the user consciously uses it sparingly. Accordingly, unnecessary wastewater is generated, and paper towels or similar items are required to dry their reusable containers, which in turn become waste.

[0022] Due to the compact design of the conveyor dishwasher according to the invention, it is particularly suitable as a reusable drinking vessel dishwasher, such as a coffee cup dishwasher, which can be displayed in the immediate vicinity of the hot drinks machine / coffee machine or even be a partially integral part of the hot drinks machine.

[0023] The conveyor dishwasher has an input area into which the soiled items (especially drinking vessels) are placed. Furthermore, the conveyor dishwasher has a separate output area from the input area, from which the clean items can be removed.

[0024] The items to be washed (drinking vessels such as cups, glasses, etc.) can be added and removed individually (i.e. one at a time); however, loading in smaller groups is also possible.

[0025] In particular, the dishwasher according to the invention is a type of hybrid dishwasher that combines the technology of stationary programmable dishwashers for batch processes with the technology of conveyor dishwashers designed for continuous operation. On the one hand, the dishwasher according to the invention offers the advantage of stationary programmable dishwashers designed for batch processes, while on the other hand, it also utilizes the advantages of conveyor dishwashers. The space required to install the dishwasher according to the invention corresponds at most to the space required for a dishwasher designed as a stationary programmable dishwasher, while at the same time enabling continuous operation of the dishwasher, as is known and cited as an advantage of conveyor dishwashers.

[0026] In particular, it is conceivable in this context that the transport device is configured to selectively transport either a predetermined group of items to be cleaned in batches from the set-up area through the at least one treatment zone and then deliver the group of items to the removal area as cleaned items, or to transport the items to be cleaned individually from the set-up area through the at least one treatment zone and then deliver them to the removal area as cleaned items. This allows, in particular, individualized treatment and individualized delivery of the treated items to the removal area.

[0027] In other words, a dishwasher user can place his or her personal cup into the dishwasher's setting area, ensuring that this personal cup is identifiably dispensed at the dispensing area.

[0028] The dishwasher is therefore particularly suitable for coffee shops where customers bring their own cups, but these cups must be cleaned on-site before being filled with a hot beverage, for example. The cups to be cleaned can then be transported individually from the loading area through the treatment zone and then fed to the unloading area.

[0029] By dividing the dishwasher into an under-counter area, in which the technology is essentially housed, and an above-counter area, which has the washing and loading area, the dishwasher according to the invention can be ideally integrated into a counter system, in particular in a coffee shop.

[0030] It is advisable for the dishwasher's loading area to be accessible from the area assigned to the coffee shop's customer, in particular exclusively from this area of ​​the counter system, while the dishwasher's unloading area is accessible from the area of ​​the counter system assigned to the counter staff. The dishwasher's loading area corresponds to the "unclean area" in the sense of commercial dishwashing. This "unclean area" of the dishwasher, which may be part of the counter system, is preferably only accessible from the area of ​​the counter system assigned to the customer. This ensures a secure separation between the area "behind the counter" and the "area in front of the counter."

[0031] This measure minimizes or even eliminates the risk of environmental contamination caused by containers (cups, etc.) that are not or not properly cleaned in the area of ​​the operational facilities required for filling the containers.

[0032] On the other hand, the dishwasher's removal area corresponds to the "clean area" in the sense of commercial dishwashing. This "clean area" of the dishwasher, if part of the counter system, is preferably accessible exclusively by counter staff.

[0033] This measure ensures that no customer-owned containers, especially cups, can enter operational areas where perishable food is openly handled. In particular, it effectively prevents staff from handling customer-owned reusable containers "behind the counter" without first treating them hygienically.

[0034] Preferably, all components belonging to the dishwasher's technology are integrated into the undercounter area of ​​the dishwasher, thus keeping the area above the counter as clear as possible, which is a basic requirement for integrating the dishwasher into a countertop system. According to implementations of the dishwasher according to the invention, at least one of the following components is integrated, at least partially, into the undercounter area of ​​the dishwasher: - a rinse aid dosing system for, in particular, selectively and / or as required, dosing of rinse aid to the cleaning liquid to be sprayed in the at least one treatment zone; - a cleaning agent dosing system for, in particular, selectively and / or as required, dosing a cleaning chemical into the cleaning liquid to be sprayed in the at least one treatment zone; - a washing tank for at least temporarily storing the cleaning liquid to be sprayed in the at least one treatment zone and / or for temporarily storing the cleaning liquid sprayed in the at least one treatment zone; - a rinse aid tank for providing liquid to be sprayed in the at least one treatment zone, to which rinse aid may be added; - a waste water tank for at least temporarily storing waste water generated during the cleaning of the washware; and / or - a water heater (English: booster) for heating, in particular selectively and / or as required, the cleaning liquid to be sprayed in at least one treatment zone.

[0035] Of course, this list is not exhaustive. It also goes without saying that not all of the above-mentioned components belonging to the dishwasher's "technology" have to be integrated into the undercounter area of ​​the dishwasher, especially not completely integrated.

[0036] In a preferred embodiment of the dishwasher, it has a body with an upper horizontal level which lies below the counter level, wherein the under-counter area of ​​the dishwasher is defined or formed by the body.

[0037] The term "carcass" used herein refers specifically to the supporting part of the dishwasher (supporting frame). The carcass may include side panels, a top and bottom shelf, and a rear panel, although this is not mandatory. Additionally, the carcass may include fixed center panels, fixed intermediate shelves, and front panels.

[0038] Preferably, the body of the dishwasher is supported by, in particular, height-adjustable feet or casters, or by a, in particular, height-adjustable substructure, base, frame, or the like. This measure allows the counter height, i.e., the counter level of the dishwasher, to be adjusted vertically and, in particular, to be adapted to counter concepts or counter systems, especially existing counter systems.

[0039] In this context, it is particularly conceivable for the upper horizontal level of the cabinet to be designed as an upper floor, at least in part. This measure allows the dishwasher to be integrated directly into an existing countertop system without interrupting the countertop level.

[0040] In the area of ​​the at least one treatment zone, the upper floor of the body should preferably have at least one passage or through-passage through which at least cleaning liquid can be transferred from the under-counter area, ie from the technology accommodated in the under-counter area, to the over-counter area, and in particular to the at least one treatment zone of the dishwasher, and vice versa.

[0041] The transport device is preferably arranged at least partially in the above-counter area of ​​the dishwasher, in particular below the at least one treatment zone. For this purpose, it is advisable for the transport device to be arranged at least partially in a base provided at least partially in the under-counter area of ​​the dishwasher.

[0042] In one conceivable implementation of the solution according to the invention, the transport device of the dishwasher has at least one transport track, in particular in the form of a conveyor belt, wherein this at least one transport track is designed to guide through at least one treatment zone of the dishwasher. In this context, it is particularly conceivable for the width of the transport track to be selected to be correspondingly narrow. In a preferred implementation of the dishwasher according to the invention, the at least one transport track thus has an effective width of preferably a maximum of 30 cm and even more preferably a maximum of 15 cm.

[0043] Especially for larger coffee shops, it is advantageous if the transport device has at least two parallel transport tracks, each in the form of a conveyor belt, to increase the cleaning performance of the dishwasher. To ensure that each of these two transport tracks can individually transport the wash items through at least one treatment zone, a correspondingly (small) width of the transport tracks should be selected. An effective width of a maximum of 30 cm and preferably a maximum of 15 cm has proven particularly advantageous.

[0044] The dishwasher according to the invention is designed as a so-called “carousel machine”.

[0045] In the carousel machine design, it is provided that - viewed from above - the setting area, the at least one treatment zone and the removal area of ​​the dishwasher are arranged in a circle or at least in a circular segment.

[0046] In the embodiment as a carousel machine, it is further preferably provided that the transport device is designed to transport items to be washed, in particular in batches or individually, at least partially in a circular movement from the setting area through the at least one treatment zone to the removal area.

[0047] When designed as a carousel machine, the transport device should in particular be designed such that, especially during the transport of the items to be washed through the at least one treatment zone, the movement of the items to be washed is preferably a non-uniform movement and even more preferably a temporally interrupted and / or delayed movement, in which the items to be washed are temporarily stopped in the at least one treatment zone of the dishwasher and / or in which the movement of the items to be washed is delayed.

[0048] In particular, it is advantageous that the dishwasher has a corresponding control device which is designed to control the at least one transport device in such a way that the items to be cleaned are transported by the at least one transport device, in particular discontinuously, from the setting area of ​​the dishwasher through the at least one treatment zone to the removal area of ​​the dishwasher.

[0049] "Discontinuous" in this context means that, for example, the items to be cleaned are transported from the set-up area to at least one treatment zone using the transport device. The transport device then stops and the items are cleaned in a stationary manner in the treatment zone (wash phase, final rinse phase, or optionally subsequent drying phase, and any disinfection phase provided). The cleaned items are then transported to the removal area using the transport device. By performing different treatments one after the other in one and the same treatment zone, the space required by the dishwasher is reduced.

[0050] Alternatively, it is of course also conceivable for the dishwasher to have a control device configured to control the at least one transport device in such a way that the items to be cleaned are transported continuously, in particular at a predetermined or definable transport speed, through the at least one treatment zone. In this context, however, at least two treatment zones should be arranged one after the other in the transport direction of the items.

[0051] In the case of dishwashers designed as carousel machines, the transport device can have a horizontal and in particular circular support surface which is rotatable about a vertical axis of rotation relative to the machine frame of the dishwasher, wherein the support surface is preferably designed as a sieve or grid.

[0052] The setting area, the at least one treatment zone, and the removal area of ​​the dishwasher should be arranged with respect to the footprint of the transport device in such a way that, at any given time, a first circular segment area of ​​the footprint is present in the setting area, a second circular segment area of ​​the footprint is present in the area of ​​the at least one treatment zone, and a third circular segment area of ​​the footprint is present in the removal area, wherein, in particular, the first, second, and third circular segment areas are preferably of equal size. In this way, a circulating system for transporting the items to be cleaned from the setting area through the at least one treatment zone to the removal area of ​​the dishwasher can be realized. Of course, other solutions are also conceivable.

[0053] As already mentioned, the dishwasher should be equipped with a control unit. In particular, this control unit can be used to select and / or adjust the necessary and / or desired treatment parameters (temperature of the cleaning fluid, nozzle pressure, dwell time, etc.) for cleaning the wash items.

[0054] According to preferred developments of the dishwasher according to the invention, the control device is particularly designed to control the washing and / or rinsing system of the dishwasher or the technology associated with the washing and / or rinsing system of the dishwasher for treating the items to be washed in the at least one treatment zone in such a way that at least one washing phase and then at least one final rinsing phase, in particular a fresh water final rinsing phase, are carried out one after the other.

[0055] In a further development of the aforementioned aspect, it is provided that the control device is further designed to control the washing and / or rinsing system of the dishwasher or the technology assigned to the washing and / or rinsing system of the dishwasher for treating the items to be washed in the at least one treatment zone in such a way that at least one disinfection phase is carried out between the at least one washing phase and the at least one final rinsing phase.

[0056] Field tests have shown that sufficient cleaning of the items to be washed can be achieved if at least one washing phase lasts between 5 and 30 seconds, preferably between 5 and 20 seconds, and more preferably about 15 seconds.

[0057] A disinfection phase should last between 1 to 10 seconds and preferably about 7 seconds, while the rinsing phase should last between 1 to 10 seconds, preferably between 2 to 8 seconds and more preferably between 3 to 5 seconds.

[0058] Of course, significantly longer times for the washing phase, disinfection phase and / or rinsing phase are also conceivable, but longer periods would be disadvantageous when using the dishwasher in the counter area, especially in a coffee shop.

[0059] This aspect is based on the consideration that the dishwasher should advantageously be designed in such a way that the complete cleaning of wash items can be carried out within approximately 30 to 60 seconds, i.e. within the usual time period in which an order can be taken and billed by the counter staff.

[0060] Accordingly, especially because the dishwasher's loading area is accessible from the area of ​​the counter system assigned to the customer, the customer can place their own reusable container through the dishwasher's loading area when ordering from the counter staff. After the ordering and billing process, which typically takes between 30 and 60 seconds, the cleaned, customer-owned reusable container is then available at the dishwasher's loading area, preferably within the immediate reach of the counter staff. Therefore, no additional travel is required by the counter staff when (re)filling a reusable container brought by the customer.

[0061] In this context, according to preferred embodiments, the control device associated with the dishwasher is designed to control the transport device of the dishwasher, in particular depending on a selected and / or set treatment program. In particular, the control device is designed to control the transport device in such a way that: - Items to be washed are transported from the setting area to the at least one treatment zone within 1 to 5 seconds, preferably within 1 to 3 seconds, and more preferably within about 2 seconds; and / or - items to be washed are transported through the at least one treatment zone within 10 to 50 seconds, preferably within 15 to 40 seconds, and more preferably within about 30 seconds; and / or - Items to be washed are transported from the at least one treatment zone to the removal area of ​​the dishwasher within 1 to 5 seconds and preferably within 1 to 3 seconds and more preferably within about 2 seconds.

[0062] Of course, longer periods for the corresponding transport of the wash items are also conceivable, although the above-mentioned periods are preferred in order to ensure that complete cleaning and loading and unloading of the wash items can be implemented within the time window of 30 to 60 seconds.

[0063] In general, it is advantageous if the dishwasher's control device is designed to automatically detect when a dish item is inserted into the dishwasher's setting area, in order to then activate the transport device and the technology belonging to the dishwasher's washing and / or rinsing system. As soon as the cleaned dish items are dispensed from the dishwasher's unloading area, the control device should automatically deactivate the transport device and, in particular, the technology belonging to the dishwasher's washing and / or rinsing system, provided no further dish items are detected in the dishwasher's setting area.

[0064] The dishwasher according to the invention significantly reduces resources (water, energy, and chemicals), especially when handling customer-owned reusable tableware in a counter-service system. Previous counter-service systems are not designed to hygienically provide customer-owned reusable containers to the operating staff "behind the counter." Rather, it is currently common practice for customers' own reusable containers to be cleaned in a dishwasher outside the counter area. However, such dishwashers are generally designed to clean a large number of items simultaneously.

[0065] In practice, this means that when customers are offered the option of (re-)filling their own reusable containers, the reusable containers are cleaned individually in a dishwasher that is not part of the counter system, which inevitably results in increased water, energy and chemical consumption.

[0066] In this context, it should be noted that the dishwasher according to the invention, for example, has a fresh water consumption of approximately 0.2 to 0.3 liters per reusable cup, with an energy consumption of 200 W / h. This can thus achieve water savings of between 50% and 70% and energy savings of the same magnitude.

[0067] Since the dishwasher according to the invention is particularly designed to clean individual items of washware in batches, a particularly compact design of the dishwasher can be realized.

[0068] According to a further development of the dishwasher according to the invention, it is provided in particular that a fresh water tank is integrated in the under-counter area of ​​the dishwasher, which can preferably be connected to the fresh water network in terms of flow, in particular as required, for supplying fresh water to the dishwasher.

[0069] Alternatively or additionally, it is conceivable that a waste water tank is integrated in the under-counter area of ​​the dishwasher, which can preferably be connected to the waste water network as required, for the temporary storage of waste water generated during operation of the dishwasher.

[0070] With these precautions, the integration of a dishwasher into the counter system is possible even if the counter system itself is not connected or connectable to the fresh water network and / or waste water network.

[0071] In this context, it can preferably be provided that a heat exchanger system is assigned to the waste water tank in order to recover, if necessary, at least part of the thermal energy of the waste water generated during operation of the dishwasher and to use it, for example, to heat the fresh water required during operation of the dishwasher.

[0072] In particular, the dishwasher according to the invention is a type of hybrid dishwasher that combines the technology of stationary programmable dishwashers for batch processes with the technology of conveyor dishwashers designed for continuous operation. On the one hand, the dishwasher offers the advantages of stationary programmable dishwashers designed for batch processes, while on the other hand, it also utilizes the advantages of conveyor dishwashers. The space required to install the dishwasher corresponds at most to the space required for a dishwasher designed as a stationary programmable dishwasher.

[0073] In particular, by dividing the dishwasher according to the invention into an under-counter area and an over-counter area, the area on the counter surface available to the counter staff as a work surface can be used optimally, since only the counter area that corresponds to the setting area, the treatment zone and the removal area is actually “needed” by the dishwasher.

[0074] As already explained, according to further developments of the dishwasher according to the invention, it comprises a control device for controlling the transport device and the controllable components belonging to the washing and / or rinsing system (pumps, valves, heating device, etc.). The control device is preferably designed to accordingly design the transport of the washware items through the at least one treatment zone depending on the presence or absence of washware items in the input area and / or output area.

[0075] The dishwasher according to the invention is - as already stated - designed in particular for coffee shops. Due to its compact design, the dishwasher can be integrated, for example, into the counter concept of a coffee shop. The over-counter area of ​​the dishwasher preferably has a base area with dimensions of a maximum of 500 mm x 500 mm and preferably a maximum of 400 mm x 400 mm and more preferably a maximum of 250 mm x 600 mm and even more preferably a maximum of 330 mm x 330 mm or a maximum of 220 mm x 380 mm. A maximum height of 500 mm for the over-counter area is preferred. The under-counter area of ​​the dishwasher preferably has a base area with dimensions of a maximum of 400 mm x 600 mm and preferably a maximum of 300 mm x 600 mm.

[0076] Depending on the dishwasher's design, it features a door, such as a drum door, for closing an access opening leading to the dishwasher's adjustment area as needed. Instead of a door, a splash guard (or lace curtain) can also be provided at the access opening.

[0077] In particular, it is advantageous for the at least one treatment zone to be assigned an extraction device for extracting vapors, for example, also integrated in the undercounter area of ​​the dishwasher. Alternatively or additionally, it is advantageous to provide a corresponding splash guard to prevent vapors and / or liquids from escaping from the at least one treatment zone.

[0078] The dishwasher's access opening preferably has a maximum height of 330 mm and preferably a maximum height of 300 mm, and a maximum width of 350 mm and preferably a maximum width of 260 mm. This allows drinking vessels to be placed individually or side by side within the access area.

[0079] The over-counter area of ​​the dishwasher and in particular the controllable components of the over-counter area are preferably detachably connected to the under-counter area or the components of the under-counter area, in particular via at least one quick coupling or plug connection.

[0082] In the following, with reference to the illustrations in Fig. 1 to Fig. 7 describes a first exemplary embodiment of the dishwasher 1 according to the invention. The dishwasher 1 is particularly suitable for cleaning items 2 in the form of drinking vessels, in particular in the form of drinking cups, mugs, glasses, or bottles. Of course, the dishwasher 1 is also suitable for cleaning other utensils, in particular, for example, coffee spoons, drinking cup lids, etc.

[0083] For cleaning the items to be washed 2, the dishwasher 1 has a (here: a single) treatment zone 3 and a transport device 4 for transporting the items to be cleaned 2 from a setting area 5 of the dishwasher 1 through the treatment zone 3 of the dishwasher 1 to a corresponding removal area 6 of the dishwasher 1.

[0084] The transport device 4 is designed to transport washware items 2 individually or a pre-defined or definable group of washware items 2 to be cleaned in batches from the setting area 5 through the treatment zone 3 and then to feed the washware item 2 or the group of washware items 2 in the cleaned state to the removal area 6.

[0085] Specifically, the dishwasher 1 comprises a housing 16 in which the treatment zone 3 is housed. In the illustrated embodiment, the treatment zone 3 serves to sequentially carry out a washing phase, then optionally a disinfection phase, and then a final rinse phase. In principle, it is also conceivable in this context for a subsequent drying phase to take place in the treatment zone 3.

[0086] The washing phase is a cleaning phase in which the items 2 or the item 2 to be washed is washed with a washing liquid in treatment zone 3. The optional disinfection phase is a cleaning or treatment phase in which the washed item 2 is exposed to either a disinfectant chemical or hot fresh water or hot steam to achieve appropriate disinfection. The final rinse phase is a cleaning phase in which the washed item 2 and the possibly disinfected item 2 are rinsed with heated fresh water and, if necessary, added rinse aid.

[0087] To enable these process steps to be carried out, the dishwasher 1 preferably has two independent fluid systems. A first fluid system is a wash water circuit, which is responsible for washing the item(s) 2 to be washed, with the washing being carried out using recirculated water from a wash tank 10 of the dishwasher 1. The other fluid system is a fresh water system, which is responsible for the final rinse. The final rinse is—as already mentioned—carried out with fresh water, preferably with fresh water from a water heater (booster). After being sprayed in the treatment zone 3, the fresh water is also collected by the wash tank 10 of the dishwasher 1.

[0088] The main task of the final rinse is to remove any lye that may be present on the item 2 to be washed. In addition, the final rinse water flowing into the wash tank 10 during the final rinse phase serves to regenerate the wash water present in the wash tank 10.

[0089] Before fresh water is sprayed as a final rinse liquid during the final rinse phase and is thereby fed into the wash tank 10 of the dishwasher 1, an amount of wash liquid equal to the amount of fresh water is preferably pumped out of the wash tank 10.

[0090] Although in the exemplary embodiments of the dishwashers 1 according to the invention shown in the drawings only a single treatment zone 3 is used in each case, it is fundamentally also conceivable to provide a separate treatment zone for each cleaning phase, wherein the individual treatment zones are arranged spatially separated from one another, and wherein a corresponding splash guard, for example in the form of a curtain, can preferably be provided between the treatment zones in order to prevent liquid from splashing over and re-soiling of the items 2 to be washed.

[0091] However, in order to achieve the most compact design possible for the dishwasher 1, it is advantageous for the cleaning phases, or at least some cleaning phases, of the dishwasher 1 to be carried out in a common treatment chamber of the dishwasher 1. In this case, the dishwasher 1 should have a control device designed to control the transport device 4 of the dishwasher 1 such that the items 2 to be cleaned are transported discontinuously through the treatment zone 3 of the dishwasher 1 by the transport device 4.

[0092] The exemplary embodiments of the dishwashers 1 according to the invention, as schematically illustrated in the drawings, are characterized in particular by the fact that they are spatially divided into an over-counter area 7 and an under-counter area 8. The over-counter area 7 is located above a counter level 13 during the intended use of the dishwasher 1 (see Fig. 2b), while the under-counter area 8 is located below the counter level 13 during the intended use of the dishwasher 1.

[0093] In particular, it is provided that the controllable components necessary for carrying out the cleaning phases in the treatment chamber are accommodated in the under-counter area 8. In particular, these are the wash and / or rinse pump(s) 9 of the wash and / or rinse system of the dishwasher 1, i.e., those pumps assigned to the wash water circuit and the fresh water system of the dishwasher 1.

[0094] Preferably, the wash tank 10 of the dishwasher 1 and, if applicable, a wastewater tank are also located in the undercounter area 8 of the dishwasher 1. As already mentioned, the wash tank 10 serves to at least temporarily store the cleaning fluid to be sprayed in the treatment zone 3 of the dishwasher 1 or to temporarily store the cleaning fluid sprayed in the treatment zone 3.

[0095] It is further advantageous if a fresh water tank or rinse aid tank 11 is also accommodated in the under-counter area 8 of the dishwasher 1, which provides at least part of the rinse aid or fresh water to be sprayed in the treatment zone 3.

[0096] Likewise, a rinse aid dosing system for, in particular, selectively and / or as needed, adding rinse aid to the cleaning liquid to be sprayed in the treatment zone 3 and / or a detergent dosing system for, in particular, selectively and / or as needed, adding a detergent chemical to the cleaning liquid to be sprayed in the treatment zone 3 can be accommodated in the under-counter area 8 of the dishwasher 1.

[0097] The same applies to the water heater (booster), which is used to selectively and / or as needed heat the cleaning liquid (rinse liquid) to be sprayed in treatment zone 3.

[0098] On the other hand, in the above-counter area 7 of the dishwasher 1, preferably only the setting area 5, the removal area 6, and the treatment zone 3 of the dishwasher 1 are provided. The treatment zone 3 or a corresponding washing and / or spray nozzle system assigned to the treatment zone 3 is in fluid communication with the washing liquid system and rinse liquid system and the corresponding components of the washing and / or rinsing system, preferably located in the under-counter area 8 of the dishwasher 1.

[0099] The washing or spray nozzle system is preferably arranged above and / or below the treatment zone 3, although a lateral arrangement of corresponding washing and / or spray nozzles is also conceivable. In particular, at least some of the washing and / or spray nozzles are arranged below the treatment zone 3 in a corresponding base area 17, which also belongs to the undercounter area 8 of the dishwasher 1, with a spray direction directed upwards into the treatment zone 3.

[0100] The representations in Fig. 1, Fig. 2 and in Fig. 4 to 7 that the exemplary embodiment shown therein comprises a body 12 with an upper horizontal plane located below the actual counter plane 13. The undercounter area 8 of the dishwasher 1 is formed by the body 12, wherein the body 12 in this case comprises height-adjustable feet 14, by which the body 12 is supported.

[0101] The top view in Fig. 3 and the partially sectioned views in Fig. 6 and Fig. 7 shows that the upper horizontal plane of the body 12 is formed, at least in some areas, as an upper floor 15. Preferably, in the area of ​​the treatment zone 3 of the dishwasher 1, the upper floor 15 has a passage or through-passage through which the fluid systems for supplying fresh water and wash water to the wash and spray arms to the components in the under-counter area 8 are ensured.

[0102] In the embodiment shown in the drawings, the transport device 4 is arranged in the over-counter area 7 of the dishwasher 1 at least partially below the treatment zone 3, wherein in this case the transport device 4 is located at least partially in the base 17 provided at least partially in the under-counter area 8 of the dishwasher 1.

[0103] As is particularly evident in the top view in Fig. 3 can be removed, the exemplary embodiment of the dishwasher 1 shown there is provided with a transport device 4 which is designed to transport items to be washed 2 in batches, at least partially in a circular movement, from the setting area 5 through the treatment zone 3 to the removal area 6.

[0104] During the transport of the wash items 2 through the treatment zone 3, the movement of the wash items 2 is temporarily interrupted or at least delayed, so that the wash items 2 are temporarily stopped in the treatment zone 3 or the movement of the wash items 2 is delayed.

[0105] In detail, the dishwasher 1 according to Fig. 1 to Fig. 7 comprises a transport device 4 having a horizontal and, in particular, circular support surface 18 that is rotatable about a vertical axis of rotation relative to the machine frame of the dishwasher 1. The support surface 18 is preferably designed as a sieve or grid.

[0106] The setting area 5, the treatment zone 3, and the removal area 6 of the dishwasher 1 are arranged with respect to the storage area 18 of the transport device 4 such that, at any given time, a first circular segment area of ​​the storage area 18 is present in the setting area 5, a second circular segment area of ​​the storage area 18 is present in the area of ​​the treatment zone 3, and a third circular segment area of ​​the storage area 18 is present in the removal area 6. In the embodiment shown, the aforementioned circular segment areas are of equal size.

[0107] However, the present invention is not limited to a carousel solution as in the embodiment according to Fig. 1 to Fig. 7. In principle, a linear solution is also conceivable; in this context, reference should be made to the schematic representation of the over-table area 7 in Fig. 9 to Fig. 10.

[0108] In the linear solution, the setting area 5, the at least one treatment zone 3 and the removal area 6 of the dishwasher 1 are arranged in series such that the setting area 5 and the removal area 6 are arranged opposite each other with the treatment zone 3 interposed.

[0109] If a transport device 4 is used (which is not absolutely necessary, especially in the linear solution), it should be designed to transport washware items 2, especially in batches, in a translational movement from the setting area 5 through the treatment zone 3 to the removal area 6.

[0110] If in particular only a single treatment zone 3 is used, in particular when transporting the items to be washed 2 through the single treatment zone 3, the translational movement of the items to be washed 2 should preferably be a non-uniform translational movement and even more preferably a temporally interrupted and / or delayed translational movement in which the items to be washed 2 are temporarily stopped in the at least one treatment zone 3 and / or in which the movement of the items to be washed 2 is delayed.

[0111] Due to the compactness of the dishwasher 1, the loading opening of the adjustment area 5 can be correspondingly small. If—as in the exemplary embodiments shown in the drawings—the dishwasher 1 is used to clean drinking vessels, in particular reusable drinking vessels such as coffee cups, the loading opening of the adjustment area 5 can be slightly higher than the drinking vessel to be treated.

[0112] Although not shown in the drawings, the access opening of the setting area 5 of the dishwasher 1 can be assigned a guide corresponding to the drinking vessel to be cleaned in order to specify an orientation of the drinking vessel when the drinking vessel is introduced into the setting area 5.

[0113] The dishwasher 1 preferably has a control device for controlling the transport device 4 and the controllable components assigned to the treatment zone 3. The control device is designed to control the transport device 4 of the dishwasher 1 and, if applicable, the controllable components of the treatment zone 3 or of the washing and rinsing system of the treatment zone 3 depending on the presence or absence or depending on the number of drinking vessels in the setting area 5 and / or removal area 6.

[0114] In particular, the dishwasher 1 according to the invention is designed, due to its design and size, to be integrated into the counter concept of, for example, a coffee shop, so that a dirty cup can be placed in the machine by the customer in an area in front of the counter, and the clean cup can then be removed from the machine by the staff behind the counter after the cleaning process has been completed, in order to then use it directly for refilling according to the customer's order. In particular, it is provided that the technology for the washing and / or rinsing system is housed in the under-counter area 8 of the dishwasher 1, so that as much space as possible is available in the over-counter area 7 of the dishwasher 1, thus allowing the entire dishwasher 1 to be easily integrated into the counter concept of, for example, a coffee shop.

[0115] Particularly in embodiments in which the over-table area 7 is designed as a linear system (cf. Fig. 8 to 10), it is advantageous if the dishwasher 1 has a door, in particular a drum door 19, in order to close an access opening to the setting area 5 of the dishwasher 1 as needed. The door can be operated manually or automatically. With automatic operation of the door, the setting area 5 can be assigned a sensor system which is designed to detect the presence of a piece of wash ware in the setting area 5, wherein the sensor system, upon detecting a piece of wash ware in the setting area 5, controls a door mechanism in order to close the door and start a treatment program of the dishwasher 1.

[0116] The embodiment in Fig. 8 to 10, it can also be seen that, in particular, over-table areas designed as a linear system, in which the setting area 5 and the removal area 6 are arranged on opposite sides, a transport device 4 can also be dispensed with. In detail, in the case of the Fig. 8 to Fig. 10, it is provided that the item of washware 2 to be cleaned is placed manually into the treatment zone 3.

[0117] In Fig. 11a to Fig. 11c, a further embodiment of an over-counter area 7 of the dishwasher 1 according to the invention is provided, wherein the transport device 4 is designed as a carousel.

[0118] The invention is not limited to the embodiments shown in the drawings, but results from a combination of all features disclosed herein.
