Description

[0001] Arrangement for cleaning a grill grate

[0002] The invention relates to an arrangement for cleaning a grill grate or a cooking surface or baking surface or an intermediate layer for cooking or baking or for a raclette, wherein adhesions that arise or remain during grilling, cooking, baking or raclette due to the grilled food or during raclette or cooking or baking are to be removed automatically and reliably. The term "grill grate" is understood broadly, so that it also includes sheet-like arrangements with openings or perforations or a surface structure or plates, including metal or stone, or other materials and constructions suitable for grilling, baking, cooking or raclette.

[0003] The object of the invention is to provide an arrangement for cleaning a grill grate which can be cleaned reliably, quickly and easily.

[0004] With the invention, in the specified application, it is achieved that an arrangement for cleaning a grill grate is created, wherein the arrangement comprises a holder for the grill grate and a high-pressure water cleaning device with at least one spray nozzle, wherein the grill grate can be arranged vertically, obliquely or horizontally, wherein at least the holder for the grill grate and the high-pressure water cleaning device are surrounded by a housing.

[0005] Advantageously, this arrangement allows any grill grate to be cleaned reliably, thoroughly, and also very conveniently or simply for the user. Furthermore, the inventive arrangement for cleaning a grill grate also allows for environmentally friendly criteria to be considered and implemented, since the inventive arrangement provides for high-pressure water cleaning, whereas previously cleaning even greasy grill grates was done directly or regularly with considerable use of cleaning agents or solvents in or into the environment.

[0006] For example, the high-pressure water cleaning device provides a pressure of 1,000 bar. Other pressures of 500 bar, 800 bar, or 1,200 bar are also conceivable.

[0007] Advantageous embodiments of the invention are presented in the subclaims. By advantageously providing the receptacle with a shelf, storage areas, a shaft, or at least one storage surface, the grill grate can be arranged reliably and securely for cleaning.

[0008] Alternatively or additionally, the grill grate can be pushed, inserted or inserted into the holder so that the grill grate is positioned reliably and securely for cleaning without moving or shifting.

[0009] By holding and clamping the grill grate at at least one edge and / or at least one edge area, the holder facilitates a comprehensive and almost surface cleaning of the grill grate in one cleaning cycle, whereby no further areas or only a few areas may need to be subjected to at least one further cleaning cycle.

[0010] By holding and clamping the grill grate on at least two opposite ends or outer edges, the holder facilitates a comprehensive and almost complete cleaning of the grill grate in at least one cleaning cycle. Furthermore, if necessary, the number of cleaning cycles can be limited to two by gripping the grill grate.

[0011] By acting on the grill grate from one side or from opposite sides or surfaces or edges, or by holding and clamping the grill grate, a comprehensive and almost surface-wide cleaning of the grill grate as well as a reliable position during cleaning is promoted.

[0012] By having the holder parallel and / or transverse to the grill grate and / or by having the grill grate movable or movable with the holder, a comprehensive and almost surface-wide cleaning of the grill grate as well as a simple construction of the high-pressure water cleaning device is facilitated.

[0013] By incorporating pressure elements or retaining elements that can be pressurized with air or liquid, the holder can be flexibly adapted to different grill grates and to different grill grates. By having a longitudinal section and / or a tubular section, with the longitudinal section and / or the tubular section arranged vertically or horizontally, the area of ​​contact or overlap of the holder on the grill grate can be reduced, thus facilitating cleaning with each cleaning cycle.

[0014] By providing at least part of the tubular area with a protective cover, the durability of the tubular area of ​​the holder is enhanced. Furthermore, complex and expensive materials for the tubular area of ​​the holder can be eliminated.

[0015] Furthermore, the protective cover can also have a surface shape or surface structure that deflects, shapes or guides the water jet, so that a water jet hitting the protective cover is still usably and effectively deflected or guided onto the grill grate.

[0016] Because the holder is pivotable, reversible or rotatable, the grill grate can be moved more easily and automatically into a convenient position for comprehensive or complete or double-sided cleaning or specifically to or in front of the high-pressure water cleaning device.

[0017] By comprising plate-shaped, cup-shaped or suction cup-shaped holding elements and / or at least one holding arm, the reliable clamping or holding of the grill grate during cleaning is facilitated.

[0018] By allowing the high-pressure water cleaning device to be moved horizontally and / or vertically and / or across at least part of the flat surface of the grill grate, the high-pressure water cleaning device can reach the entire grill grate, thus facilitating cleaning. Furthermore, the grill grate mounting can be simplified.

[0019] By arranging the high-pressure water cleaning device on one or both sides of the grill grate, whereby the high-pressure water cleaning device acts on or is directed towards the grill grate on one or both sides, the grill grate can also be fully reached by the high-pressure water cleaning device, thus facilitating cleaning and also simplifying the attachment for the grill grate.

[0020] By arranging or aligning the high-pressure water cleaning device opposite or offset from one another, or mirroring or non-offset from one another in a double-sided high-pressure water cleaning device, the cleaning of the grill grate is facilitated because the grill grate is fully reached by the high-pressure water cleaning device.

[0021] By guiding the high-pressure water cleaning device via a Cartesian system or having a Cartesian system, the cleaning of the grill grate can also be facilitated, since the grill grate is comprehensively reached by the high-pressure water cleaning device and unfavorable or concealing structures of the holder can be avoided by appropriate alignment of the high-pressure water cleaning device.

[0022] By guiding the high-pressure water cleaning device via a cable robot system or having a cable robot system, the guidance and alignment of the high-pressure water cleaning device is facilitated.

[0023] By having at least one spray bar with spray nozzles, the high-pressure water cleaning device facilitates cleaning of the grill grate and accelerates it due to the increased effective area of ​​the high-pressure water cleaning device. Furthermore, the flexibility of the arrangement with regard to grill grate shapes is increased.

[0024] By having the high-pressure water cleaning device at least one rotating spray bar with at least one spray nozzle or at least one rotating or movable or rotating spray nozzle or at least one rotating or movable spray carriage with at least one spray nozzle or a rotating spray nozzle, the cleaning of the grill grate and also the flexibility of the arrangement with regard to the shapes of the grill grate are promoted.

[0025] By having at least one fixed or movable spray plate, the spray plate comprising distributed spray nozzles, the cleaning of the grill grate is facilitated and accelerated by the increased effective area of ​​the high-pressure water cleaning device. This also allows for more flexibility in terms of grill grate shapes.

[0026] Since the high-pressure water cleaning device comprises a spray lance with at least one spray nozzle, wherein the spray lance is movable between an area away from the holder for the grill grate and an area of ​​the holder for the grill grate, the spray lance can be removed from a cleaning area in which the holder for the grill grate is located and thus facilitates the change in position or removal of the grill grate.

[0046] Fig. 22a to 22e an arrangement for cleaning a vertically arranged grill grate with movable and displaceable holding arms as a receptacle, each holding arm comprising a movable spray nozzle.

[0047] The arrangement according to the invention, as shown in Figures 1a to 1f, for cleaning a grill grate 1, has, in the specific exemplary embodiment, a holder 2 for the grill grate 1, into which the grill grate 1 can be pushed or inserted. The grill grate 1 is arranged horizontally. The grill grate 1 is placed via an inlet opening (not shown) onto the lower level of the holder 2, which is equipped with an inflatable hose battery. During one-sided cleaning from above, the holder 2 acts on the grill grate 1 from one side, i.e., from below. The grill grate rests on the holder 2.

[0048] Grill grate 1 can only be cleaned from one side. After cleaning the first side, it must be turned over.

[0049] To turn the grill grate 1, the holder 2 acts on the grill grate 2 from opposite sides or surfaces of the grill grate 1 and holds it or clamps it. The holder 2 is reversible or rotatable. For this purpose, a hose reel 17 or

[0050] Clamping drum 17 is present. In plates at the axial ends of the hose reel 17 or clamping drum 17, two geometrically defined curved slots 15 are provided, as shown in Figures 1c and 1e, which the receptacle 2 in the form of plates equipped with pneumatically equipped hoses as an inflatable hose battery, as shown in Figure 1a, moves towards each other upon rotation of the hose reel 17 or clamping drum 17, as shown in Figure 1f. As a result, the inserted grill grate 1 or the inserted grill grates 1 are clamped, as shown in Figure 1f, and can be turned over and placed on the opposite side. The second side of the grill grate 1 can now be cleaned.

[0051] Furthermore, a high-pressure water cleaning device 3 with a spray lance 14 is provided, which comprises at least one spray nozzle 4. The high-pressure water cleaning device 3 is arranged on one side of the grill grate 1 and acts on the grill grate 1 from one side. The spray lance 14 of the high-pressure water cleaning device 3 is guided via a Cartesian system 9.

[0052] The respective spray nozzle 4 can also be designed as a rotating spray nozzle 4.

[0053] For turning the grill grate 1, the pressure lance can be moved as a spray lance 14 between an area off, i.e. outside the area of ​​the holder for the grill grate 1, and an area of ​​the holder 2, i.e. in the area of ​​or between the holders 2 for the grill grate 1, as shown in Figures 1b, 1c and 1e.

[0054] By means of a pressure lance as a spray lance 19, which is driven by an upstream Cartesian system 9, which is therefore upstream of the hose reel 17 or clamp reel 17, the grill grate 1 is cleaned with one or more high-pressure water cleaning jets from at least one spray nozzle 4 with a pressure of, for example, 1000 bar and the entire surface is coated in a digitally controlled manner.

[0055] The receptacle 2 for the grill grate 1 and the high-pressure water cleaning device 3 are surrounded by a housing 5, although the housing walls are not shown for clarity. Likewise, the grill grate 1 is only shown as a surface. A further embodiment of the arrangement according to the invention for cleaning a grill grate 1 is shown in Figures 2a to 2c, wherein a receptacle 2 for the grill grate 1 and a high-pressure water cleaning device 3 with at least one spray nozzle 4 are arranged in a housing 5. For clarity, the housing walls of the housing 5 are not shown. The grill grate 1 can be inserted vertically and arranged at an angle. The grill grate 1 can be pushed in or inserted from above via an input opening 18 and placed or set down on the lower level of the receptacle 2, i.e. parked at an angle, as shown in Figure 2c.

[0056] The high-pressure water cleaning device 3 comprises one or more spray nozzles 4 per side, as shown particularly in Figure 2c, which can be moved via a vertically arranged Cartesian system 9. This Cartesian system 9 is designed in duplicate, i.e. a Cartesian system 9 is used on both sides of the grill grate 1, as shown in Figures 2b and 2c. This allows both sides of the grill grate 1 to be cleaned at the same time. The forces acting on the grill grate 1, which are triggered by the water jets, are approximately the same on both sides. This creates a balance of forces and the grill grate 1 does not move during cleaning. The grill grate 1 is cleaned with one or more high-pressure water cleaning jets, for example at a pressure of 1000 bar, and the entire area to the left and right, i.e. on both sides, is digitally controlled and covered or scanned.

[0057] The further embodiment of the inventive arrangement for cleaning a grill grate 1, illustrated in Figures 3a and 3b, comprises a housing 5 with a hinged lid 16 that can be opened. Arranged in the housing 5 are a receptacle 2 for the grill grate 1 and a high-pressure water cleaning device 3 with at least one spray nozzle 4.

[0058] The grill grate 1 is inserted or pushed horizontally into built-in guides as a holder 2. The holder 2 is, for example, a clamp-like fastening, as shown in Figure 3a, or, for example, a rail-like fastening, as shown in Figure 3b, and acts on the grill grate 1 at the lateral edge area or from the edge during one-sided cleaning from above. A horizontal Cartesian system 9 for the high-pressure water cleaning device 3 with one or more nozzles as spray nozzles 4 is arranged in the housing cover 16. The one or more spray nozzles 4 can be moved via the Cartesian system 9. The grill grate 1 can only be cleaned from one side, the top side. After cleaning the first side, it must be turned over. An indicator signals when cleaning of a side is complete.When the indicator light, for example, turns green, the hinged cover can be opened again as housing cover 16, and the grate can be turned over as grill grate 1. The housing cover 16 is then closed again, and the other side can be cleaned. The grill grate is cleaned with one or more high-pressure water jets, for example, at a pressure of 1,000 bar, and the entire surface is digitally controlled by a spray or sweep.

[0059] As an alternative to the receptacle 2 as a clamp-like fastening as a rail-like fastening, the receptacle 2 can also comprise at least one inflatable tubular region 8 as an inflatable tubular profile 8.

[0060] Thus, as a receptacle 2, two or four of the tubular areas 8 can be arranged as tubular profiles 8 as a group above and below the grill grate 1 as an inflatable tubular battery 8.

[0061] Figures 4 and 5 show an arrangement according to the invention for cleaning a grill grate 1, in which a high-pressure water cleaning device 3 with at least one spray nozzle 4 is arranged only in the housing cover 16 as a hinged cover of a housing 5. As a receptacle 2, four tubular regions 8 as hose profiles 8 are arranged as a group above and below the grill grate 1 as an inflatable hose battery in the housing cover 16 and in the housing 5. The four tubular regions 8 as hose profiles 8 are each movable vertically, as shown in Figures 4 and 5, and also horizontally, so that the spray nozzle 4 can reliably clean the grill grate. The grill grate 1 can be clamped as a respective hose profile 8 between at least two opposite ones of the four tubular regions 8 and can also be moved laterally thereabove.

[0062] Advantageously, some of the tubular regions 8 can have a protective cover, at least in some areas, so that the spray nozzle in the region of one of the tubular regions 8 does not destroy the tubular region 8. The arrangements according to the invention for cleaning a grill grate 1 comprise a housing 5 with a hinged lid as the housing cover 16, which can be opened. Arranged in the housing 5 are a receptacle 2 for the grill grate 1 and a high-pressure water cleaning device 3 with at least one spray nozzle 4.

[0063] Furthermore, Figures 6a and 6b show an arrangement according to the invention for cleaning a grill grate 1, in which a high-pressure water cleaning device 3 with at least one spray nozzle 4 is arranged only in the housing cover 16 as a hinged lid of a housing 5. As a receptacle 2, two tubular regions 8 as hose profiles 8 are arranged as a group in the housing cover 16 and in the housing 5, opposite one another, above and below the grill grate 1 as an inflatable hose battery. The two tubular regions 8 as hose profiles 8 are each movable vertically and horizontally, as shown in Figure 6b, so that the spray nozzle 4 can clean the grill grate reliably and without obstruction. As shown in Figure 6b, the grill grate 1 can be clamped at the edge or in the edge area between two opposite of the four respective tubular regions 8 as a respective hose profile 8 and can also be moved laterally thereabove.At least when changing from one group of two opposite tubular areas 8 as tubular profiles 8 to the other group, both groups grip the grill grate 1.

[0064] Deviating from the illustrations and exemplary embodiments of Figures 3a to 6b, in particular in Figure 7a and Figures 7b to 9b of the inventive arrangements for cleaning a grill grate 1, a high-pressure water cleaning device 3 with at least one spray nozzle 4 is shown arranged both in the housing cover 16 as a hinged cover of a housing 5 and in the housing 5, i.e., above and below the grill grate arranged in the housing. A horizontal Cartesian system 9 with one or more nozzles as spray nozzles 4 is arranged for the high-pressure water cleaning device 3 in the housing cover 16 and in the housing 5. The one or more spray nozzles 4 can be moved via the Cartesian system 9. The grill grate 1 can thus be cleaned from both sides simultaneously.

[0065] In Figure 7b, the grill grate 1 can be inserted or pushed horizontally into built-in guides as a holder 2. Holder 2 is, for example, a rail-like fastening and acts on the grill grate 1 during one-sided cleaning from above at the lateral edge area or from the edge.

[0066] In Figures 8a to 8c, four tubular sections 8, each in the form of hose profiles 8, are arranged as a group above and below the grill grate 1 as an inflatable hose battery, as a receptacle 2 in the housing cover 16 and in the housing 5. The four tubular sections 8, each in the form of hose profiles 8, are movable vertically and horizontally, so that the grill grate is reliably cleaned by the spray nozzle 4. The grill grate 1 can be clamped between at least two of the four tubular sections 8, each in the form of a hose profile 8, and can also be moved laterally thereabove.

[0067] With the housing cover 16 opened, the grill grate 1 can be placed or inserted onto the built-in holder 2 in the form of tubular areas 8 as hose profiles 8 as an inflatable hose battery. The four tubular areas 8 as hose profiles 8 as an inflatable hose battery are, for example, two plates (not shown) on both sides of the grill grate 1, each equipped with four pneumatically equipped or pressurizable hoses. These can be moved towards each other in pairs, in particular opposite one another, and thus clamp or fix the grill grate 1. For example, the left two tubular areas 8 as hose profiles 8 are digitally controlled for each level and brought into the clamping position. By moving the tubular areas 8 as hose profiles 8 towards each other, the inserted grill grate 1 can be clamped on one side on the left with the level below and above.The right-hand projecting part of the upper and lower sides of the grill grate 1 can be cleaned simultaneously because the spray nozzles 4 are arranged as water jet nozzles at the top and bottom. The high-pressure water cleaning device 3, guided via the Cartesian system 9 and equipped with at least one spray nozzle 4, is digitally controlled and sweeps over or covers the entire, particularly exposed, surface of the grill grate 1 with one or more high-pressure water jets, for example at a pressure of 1,000 bar.

[0068] For the other surface section of the grill grate 1, the four tubular areas 8 are designed as hose profiles 8 as an inflatable hose battery on the, for example, two plates (not shown) are on either side of the grill grate I, each with four pneumatically equipped or pressurizable hoses, which are moved towards each other in the same way. This time, the two right-hand hoses on each level are digitally controlled and brought into the clamping position. This way, the inserted grill grate 1 is clamped on one side on the right as the levels above and below are moved towards each other. The now left-hand projecting part of the upper and lower sides of the grill grate 1 can be cleaned simultaneously because the spray nozzles 4 are arranged above and below, i.e. above and below the grill grate 1, as described above.The high-pressure water cleaning device 3, which is guided via the Cartesian system 9 with two horizontal axes and one vertical axis and has at least one spray nozzle 4, is digitally controlled and sweeps over or covers the entire, in particular exposed, surface of the grill grate 1 with one or more high-pressure water cleaning jets, for example at a pressure of 1000 bar.

[0069] As shown in Figures 9a and 9b as an inventive arrangement for cleaning a grill grate 1, the grill grate 1 can have two tubular regions 8 as hose profiles 8 as a group above and below the grill grate 1 as an inflatable hose battery, as a receptacle 2 in the housing cover 16 and in the housing 5. The two tubular regions 8 as hose profiles 8 are each movable vertically and horizontally, so that the grilled toast can be reliably cleaned by means of the spray nozzle 4. The grill grate 1 can be clamped as a respective hose profile 8 between at least two of the four tubular regions 8 opposite one another and can also be moved laterally thereabove.

[0070] Likewise, with the housing cover 16 folded open, the grill grate 1 can be placed or inserted onto the built-in holder 2 in the form of tubular areas 8 as hose profiles 8 as an inflatable hose battery. The two tubular areas 8 as hose profiles 8 as an inflatable hose battery are each equipped with two pneumatically equipped or pressurizable hoses. These can be moved in pairs opposite one another and thus clamp or fix the grill grate 1. For example, the left and / or right tubular area 8 as hose profile 8 are digitally controlled for each level and brought into the clamping position. By moving the tubular areas 8 as hose profiles 8 towards one another, the inserted grill grate 1 can be clamped on one side on the left and / or right with the level below and above, as shown for the right side in Figure 9b.The right or, as shown in Figure 9b, the left projecting part of the upper and lower sides of the grill grate 1 can now be cleaned simultaneously because the spray nozzles 4 are arranged as water jet nozzles at the top and bottom. The high-pressure water cleaning device 3, guided via the Cartesian system 9 and equipped with at least one spray nozzle 4, is digitally controlled and sweeps over or covers the entire, particularly exposed, surface of the grill grate 1 with one or more high-pressure water jets, for example, at a pressure of 1,000 bar.

[0071] In the exemplary embodiments according to Figures 10 to 16, in the arrangements according to the invention for cleaning a grill grate 1, the high-pressure water cleaning device 3 is guided via at least one cable robot system 10, as shown by way of example in Figure 11. Furthermore, the arrangement according to the invention for cleaning a grill grate 1 comprises a housing 5 with a hinged lid as the housing cover 16. Arranged in the housing 5 are a receptacle 2 for the grill grate 1 and the high-pressure water cleaning device 3 with at least one spray nozzle 4. The respective spray nozzle 4 can also be designed as a rotating spray nozzle 4.

[0072] As shown in Figures 12a and 12b, a high-pressure water cleaning device 3 is mounted only in the housing cover 16 via a cable robot system 10, and is thus arranged horizontally during operation. Accordingly, only one-sided cleaning of the grill grate is provided, and the grill grate must be turned over to clean the other side.

[0073] In Figures 13a and 13b, a high-pressure water cleaning device 3 is arranged in the housing cover 16 and a high-pressure water cleaning device 3 is arranged in the housing 5. This allows both sides of the grill grate to be cleaned simultaneously, or at least without turning. In this example, the cable robot systems 10 are also arranged horizontally during operation.

[0074] The receptacles 2 are, as described above for Figures 3a and 3b, provided, for example, as a rail-like fastening, as shown in Figure 10.

[0075] Furthermore, receptacles with tubular areas 8 as tubular profiles 8, as described above for Figures 8a to 9b, are also used, as shown in Figures 12a to 13b and 15a to 16.

[0076] According to Figures 12a and 12b, two tubular regions 8, as shown in Figures 13a and 13b, or four, as shown in Figures 12a and 12b, are arranged as a group above and below the grill grate 1 as an inflatable hose battery as a receptacle 2 in the housing cover 16 and in the housing 5. The two or four tubular regions 8, as hose profiles 8, are each movable vertically, as shown in Figures 12b and 13b, and also horizontally, as shown in Figure 13b, so that the grilled toast can be reliably cleaned using the spray nozzle 4. The grill grate 1 can be clamped as a respective hose profile 8 between at least two opposite ones of the two or four tubular regions 8 and can also be moved laterally thereabove.

[0077] As already described above, with the lid as housing cover 16 opened, the grill grate can be inserted onto the built-in guides. The tubular areas 8 as hose profiles 8 are arranged as a group, for example on two plates (not shown), on both sides of the grill grate 1, each with four, as shown in Figures 12a and 12b, or two, as shown in Figures 13a and in particular 13b, pneumatically equipped hoses and are moved towards each other in pairs to clamp the grill grate 1. For each level, the two left or right opposite hoses or, as shown in Figures 13a and in particular 13b, the two opposite hoses are digitally controlled and brought into the clamping position. In this way, the top and bottom levels are moved towards each other and the inserted grill grate 1 is clamped on one side on the left or right.The corresponding right or left projecting part of the grill grate can, as shown in Figures 12a and 12b, be cleaned only from above, while, as shown in Figures 13a and 13b, the upper and lower sides of the grill grate 1 are cleaned simultaneously, since the water jet nozzles, as spray nozzles 4 of the high-pressure water cleaning device 3, are arranged above and below the cable robot system 10 (with two horizontal axes and one vertical axis). Using the spray nozzles 4, one or more high-pressure water cleaning jets, for example at a pressure of 1000 bar, can be digitally controlled to cover the corresponding area.

[0078] Further embodiments of the arrangements according to the invention for cleaning a grill grate (1) according to Figures 14a to 16 provide for two high-pressure water cleaning devices (3), each having a vertically arranged cable robot system (10), between which the grill grate 1 is arranged or can be arranged. In addition, a receptacle 2 for the vertical fixation of the grill grate 1 is provided. Accordingly, here too, the cover can be opened as a housing cover 16 and the grill grate 1 can be placed on or between the vertically installed guides. The receptacle (2) can, as described above, be a rail-like fastening, for example, and acts, as shown in Figures 14b and 14c, on the lateral edge area or on the edge area above and below or from the edge on the grill grate (1).

[0079] Furthermore, as described above, tubular sections 8 can also be used as hose profiles 8 as a group of hydraulically or pneumatically pressurized hoses, which are arranged vertically like the cable robot systems (10) of the high-pressure water cleaning devices (3). Thus, on both sides of the grill grate 1, as shown in Figures 15a and 15b, two or, as shown in Figure 16, four tubular sections 8 as hose profiles 8 are present as a group of hydraulically or pneumatically pressurized hoses, and can be moved in pairs opposite one another to clamp the grill grate 1.For each level, as shown in Figures 15a and 15b, the left or right opposing hoses, or, as shown in Figure 16, the two left or right opposing hoses, are digitally controlled and brought into the clamping position, and the inserted grill grate 1 is clamped on one side on the left or right. The corresponding right or left projecting part of the grill grate 1 can, as shown in Figures 15a and 15b, be cleaned on both sides simultaneously, since the water jet nozzles, as spray nozzles 4 of the high-pressure water cleaning device 3, are arranged laterally above the cable robot system 10 with two vertical axes and one horizontal axis. By means of the spray nozzles 4, the corresponding area can be digitally controlled with one or more high-pressure water cleaning jets (for example, at a pressure of 1000 bar).

[0080] Further embodiments of the arrangement according to the invention for cleaning a grill grate (1 according to Figures 17a to 17c) provide for a high-pressure water cleaning device (3) to be present, which has two vertically movable spray bars (11) with spray nozzles (4), between which the grill grate 1 is also arranged or can be arranged vertically and whereby the grill grate 1 can be cleaned on both sides.

[0081] In addition, there is a receptacle 2 for the vertical fixation of the grill grate 1, which, as described above, is for example a rail-like fastening, as shown in Figures 17a and 17b, holds the grill grate (1) at the lateral edge area or at the edge area above and below or from the edge.

[0082] Furthermore, as described above, tubular areas 8 can also be used as hose profiles 8 as a group of hydraulically or pneumatically pressurizable hoses, which, as shown in Figure 17c, are arranged horizontally in the upper and lower areas of the vertical grill grate 1. Thus, on either side of the grill grate 1, two horizontally arranged tubular areas 8 as hose profiles 8 as a group of hydraulically or pneumatically pressurizable hoses are present and can be moved horizontally towards each other in pairs to clamp the grill grate 1. Depending on the area to be cleaned, the upper or lower opposing hoses are digitally controlled and brought into the clamping position, and the inserted grill grate 1 is clamped accordingly in the upper or lower area.The corresponding lower or upper projecting part of the grill grate 1 can be cleaned simultaneously on both sides, since the water jet nozzles, as spray nozzles 4 of the spray bar 11 of the high-pressure water cleaning device 3, can each be moved vertically along the grill grate 1. Using the spray nozzles 4, the corresponding area can be digitally controlled with several high-pressure water cleaning jets, for example, at a pressure of 1000 bar.

[0083] Furthermore, the lid can also be opened accordingly as a housing cover 16 and the grill grate 1 can be placed on or between the vertically or vertically stacked guides.

[0084] Alternatively, in an arrangement according to the invention (not shown) for cleaning a grill grate (1), two vertical plates are provided with four pneumatically equipped hoses, each equipped as an inflatable hose profile 8, as an inflatable hose section 8. These are moved towards each other. For each vertical level, the two left or right hoses are digitally controlled and brought into the clamping position. As a result, the vertical levels on the left and right are moved towards each other, and the vertically inserted grill grate 1 is clamped on one side on the left or right. The right or left projecting part of the left and right side of the grill grate 1 can be cleaned simultaneously because the water jet nozzles are arranged as spray nozzles 4 on the left and right.The two vertically movable spray bars 11, equipped with spray nozzles 4 for the high-pressure water jets (for example with a pressure of 1000 bar), clean the free projecting vertical surface of the grill grate 1.

[0085] In further embodiments of the arrangement according to the invention for cleaning a grill grate (1) according to Figures 18a and 18b as well as 19a and 19b, in contrast to the embodiments according to Figures 17a and 17b and 17c, instead of the vertically moved spray bar 11, a high-pressure water cleaning device (3) with a rotating or movable spray nozzle (4) or at least one rotating or movable spray carriage (12) with at least one spray nozzle (4) is used, which or whose rotating path is also vertically movable. This allows the grill grate 1 to be cleaned all around. The respective spray nozzle 4 can also be designed as a rotating spray nozzle 4.

[0086] For a more detailed description of the respective receptacle 2 with respect to the embodiment according to Figures 18a and 18b, reference is made to the description of the embodiments of Figures 17a and 17b, and for a more detailed description of the respective receptacle 2 with respect to the embodiment according to Figures 19a and 19b, reference is made to the description of the embodiment of Figure 17c.

[0087] Furthermore, the lid can also be opened accordingly as a housing cover 16 and the grill grate 1 can be placed on or between the vertically or vertically stacked guides.

[0088] Alternatively, in an inventive arrangement (not shown) for cleaning a grill grate 1, two vertical plates are equipped with four pneumatically equipped hoses, each forming an inflatable hose-shaped section 8, forming an inflatable hose profile 8. These hoses can be moved toward one another. For each vertical plane, the two left-hand hoses are digitally controlled and brought into the clamping position. This moves the left and right vertical planes toward one another, and the vertically inserted grill grate is clamped on one side, either on the left or right. The right or left projecting portion of the left and right sides of the grill grate can be cleaned simultaneously because the water jet nozzles are arranged on a spray bar running along the left.A spray bar 11, which can be moved vertically on the left or right side and rotates horizontally as a spray carriage 12 of the high-pressure water cleaning device 3, equipped with water jet nozzles as spray nozzles 4 for high-pressure water cleaning jets, for example with a pressure of 1000 bar, cleans the free projecting vertical surface.

[0089] Further embodiments of the arrangement according to the invention for cleaning a grill grate 1 according to Figures 20a to 21c provide for a high-pressure water cleaning device 3 which has a spray plate 13, wherein the spray plate 13 comprises distributed spray nozzles 4, between which the grill grate 1 is arranged or can be arranged horizontally and whereby the grill grate 1 can be cleaned on both sides.

[0090] According to the embodiment shown in Figure 20a, a spray plate 13 is arranged in the housing cover 16 and a spray plate 13 in the housing 5 as the high-pressure water cleaning device 3. The grill grate 1 can be placed or inserted onto the spray plate 13 in the housing 5, which also functions as a holder 2. For cleaning, the housing cover 16 can be closed, and cleaning is carried out using the spray plates 13 in the housing cover 16 and in the housing 5 and the spray nozzles 4 provided therein for the high-pressure water cleaning jets, for example, at a pressure of 1000 bar.

[0091] Advantageously, the spray plate 13 is displaceable horizontally, as shown in Figure 20b and particularly in Figure 20c. Accordingly, in the embodiment shown in Figure 20b, the grill grate 1 can be placed on or inserted into the housing 5. For cleaning with the housing cover 16 closed, the spray plate 13 is displaceable horizontally within the housing cover 16 and within the housing 5, thus reaching the entire surface of the grill grate 1.

[0092] The further embodiment of the arrangement according to the invention for cleaning a grill grate 1 provides a horizontally displaceable spray plate 13 with distributed spray nozzles 4 as a high-pressure water cleaning device 3 in the housing cover 16 and in the housing 5 according to Figures 21a to 21c, wherein tubular regions 8 as hose profiles 8 are provided as receptacles 2. It is provided that two tubular regions 8 as hose profiles 8 in the housing cover 16 and two tubular regions 8 as hose profiles 8 in the housing 5 are each arranged laterally and parallel to the spray plate 13 and are vertically and horizontally displaceable. The tubular regions 8 as hose profiles 8 are hydraulically or pneumatically actuated hoses.Accordingly, on either side of the grill grate 1, two horizontally arranged tubular areas 8 are provided as hose profiles 8 as a group of hydraulically or pneumatically pressurizable hoses. These hoses can be moved vertically relative to one another in pairs to clamp the grill grate 1. Depending on the area to be cleaned, the upper or lower opposing hoses are digitally controlled and brought into the clamping position, as shown in Figure 21b, and the inserted grill grate 1 is clamped accordingly in the lateral area. The unused tubular areas 8 as hose profiles 8 can be moved out of the cleaning area, as also shown in Figure 21b.When changing sides between the tubular areas 8 as tubular profiles 8, all tubular areas 8 as tubular profiles 8 clamp the grill grate 1 for a moment, as shown in Figure 21c.

[0093] The corresponding laterally projecting part of the grill grate 1 can be cleaned on both sides simultaneously using the movable spray plate 13, since the water jet nozzles, as spray nozzles 4 of the spray plate 13 of the high-pressure water cleaning device 3, are each directed vertically onto the grill grate 1. Using the spray nozzles 4, the corresponding area can be digitally controlled with several high-pressure water cleaning jets, for example, at a pressure of 1,000 bar.

[0094] Furthermore, the lid can also be opened accordingly as a housing cover 16 and the grill grate 1 can be placed on or between the vertically or vertically stacked guides.

[0095] Alternatively, in an arrangement according to the invention (not shown) for cleaning a grill grate 1, two horizontal plates are equipped with four pneumatically equipped hoses, each forming an inflatable hose-shaped section 8, forming an inflatable hose profile 8. These hoses can be moved towards one another. For each horizontal plane, the left or right two hoses are digitally controlled and brought into the clamping position on the grill grate 1. The horizontal planes are moved towards one another on the left and right, and the horizontally inserted grill grate is clamped on one side on the left or right. The right or left projecting part of the left and right side of the grill grate 1 can each be cleaned on both sides, i.e. from above and below at the same time, because the many stationary water jet nozzles are arranged as spray nozzles 4 on a spray plate 13 above and below the grill grate 1.A large number of spray nozzles 4 in or on the spray plate 13 provide high-pressure water cleaning jets, for example with a pressure of 1000 bar, for cleaning the free right or left cantilevered horizontal surface on both sides.

[0096] A further embodiment of the arrangement according to the invention for cleaning a grill grate 1 is shown in Figures 22a to 22e. Here, the grill grate 1 is or will be arranged vertically. The arrangement provides a receptacle 2 for the grill grate 1 and a high-pressure water cleaning device 3 with at least one spray nozzle 4. The receptacle 2 for the grill grate 1 and the high-pressure water cleaning device 3 are surrounded by a housing 5, as shown in Figure 22c. The arrangement comprises, as shown in Figure 22c, an input opening 18 into which the grill grate 1 can be pushed or inserted into the housing and / or the receptacle 2. The receptacle 2 comprises four holding arms 19, with plate-shaped, cup-shaped, or suction cup-shaped holding elements 7 being arranged on each of the holding arms 19. Two holding arms 19 are arranged adjacent to one another at a distance from one another in parallel.The holding elements 7 on the holding arms 19 are arranged opposite one another and facing one another on the respective holding arms 19.

[0097] The holding arms 19, each arranged adjacent to one another at a height and spaced parallel to one another, can be pivoted parallel and transversely to the grill grate 1 from an open position into a closed position, thus holding the grill grate, as shown in Figures 22d and 22e. The holding elements 7 are arranged on the holding arms 19 such that, in the holding position of the holding arms 19, the holding elements 7 act on the grill grate 1 from opposite surfaces and hold and clamp the grill grate 1, as shown in Figure 22e.

[0098] Furthermore, the holding arms 19 can be vertically displaced or moved as a receptacle in pairs alone and / or with the grill grate 1 as required, as shown in Figure 22a.

[0099] The high-pressure water cleaning device 3 with a horizontally movable spray nozzle 4 is provided on each of the support arms 19. The spray nozzle 4 can also be arranged in a movable spray carriage 12.

[0100] It is intended that initially the pair of upper or lower two holding arms 19, which are arranged adjacent to one another at a height and spaced parallel to one another, hold the grill grate 1 in the closed position. The other two correspondingly lower or upper two holding arms 19, which are arranged adjacent to one another at a height and spaced parallel to one another, are in an open position in which a vertical movement of the holding arms 19 is possible. In addition to the vertical movement of the holding arms 19, the horizontally movable spray nozzles 4 move on the holding arms 19 in the open position. The movable spray nozzles 4 or the movable spray carriages 12 can each be driven by means of toothed belts, as shown in Figure 22b.

[0101] By means of the spray nozzle, the high-pressure water cleaning jets can be provided, for example, with a pressure of 1000 bar to clean the free surface of the grill grate 1, ready on both sides.

[0102] Thus, the high-pressure water cleaning device 3 can be moved horizontally and vertically and over at least part of the planar extent of the grill grate 1. Furthermore, the high-pressure water cleaning device 3 is arranged on both sides of the grill grate 1, with the high-pressure water cleaning device 3 acting on or being directed at the grill grate 1 from both sides.

[0103] In the double-acting high-pressure water cleaning device 3, the high-pressure water cleaning devices 3 can be arranged or aligned opposite or offset from one another. Likewise, the high-pressure water cleaning devices 3 can be arranged or aligned opposite one another in a mirrored manner or without offset.

[0104] Alternatively, the respective high-pressure water cleaning device 3 is also provided with a spray bar 11 with spray nozzles 4, which can be moved vertically and over at least a portion of the flat extension of the grill grate 1 with the respective support arm 19 of the holder 2.
