Description

Technical Field

[0001] The invention relates to a device for holding and mechanically cleaning the inner surface of a hollow body, preferably a bottle or the like, which is arranged for use at a pull-out cutlery basket for a dishwasher, wherein the device consists of an elongated support rail which is provided with clamping elements along its longitudinal axis in order to provide a detachable clamping connection to the cutlery basket. Background Art

[0002] Devices for washing bottles or the like are already known in the prior art as bottle washing devices. For this purpose, reference is made, for example, to German documents DE 10 2020 110 229 A1, DE 2020 20 110 139 A1 or DE 10 2009 039585 A1. The document discloses a bottle washing machine for washing reusable bottles in the beverage industry. In the technical facilities and embodiments for washing the reusable bottles used, known lye baths and lye sprayers (also called lye softening) are used to soften dirt, labels, glue residues, etc. Here, it is common to immerse the bottles completely in the lye bath to treat the outside of the bottles and the inner space of the bottles. In addition, the bottle washing machine usually includes a bottle feeder and a bottle conveyor, which moves the bottles through the facility. The conveyor is surrounded by a support and a nozzle for the bottles, by which the bottles are transported in an inverted manner, that is, with the opening downward, and the nozzle sprays a cleaning liquid from the outside through the bottleneck into the bottles passing by for washing. It has proven to be disadvantageous that this type of cleaning of the inner surfaces of bottles, for example, is not usable in dishwashers. This technology with a conveyor device that moves through the facility in a conveying direction, in which the bottles are guided past nozzles, cannot be used in dishwashers.

[0003] Document DE 10 2011 082 702 B4 discloses a nozzle arrangement, in particular for cleaning inner surfaces of a cavity by means of at least one nozzle for generating at least one spray jet. A disadvantage of the nozzle is that the embodiment is not suitable for holding and cleaning bottles in a dishwasher.

[0004] The tableware washing basket for dishwashers is also known from the prior art. For example, the tableware washing basket in the document DE 1510 2012 219 818 A1 is mentioned here. This tableware washing basket is used to accommodate washing objects, in particular a variety of different tableware pieces. There is a rotatable spray arm below this tableware washing basket, which sprays the washing liquid to the dishes with its nozzle and then washes them. The great disadvantage of this cleaning is that the arrangement of the nozzle on the rotating spray arm and the nozzle itself are not suitable for washing the inner surface of the bottle through the narrowed bottleneck. In addition, the tableware washing basket is not suitable for holding long objects such as bottles, because the object must be stably maintained on the frame or tableware washing basket in an inverted, upright posture to be reliably washed and dried during the washing cycle. The known 1 to 2 liter water bottle composed of glass or plastic cannot be placed vertically due to insufficient space in the tableware washing basket. There is also no suitable support for baby bottles.

[0005] The device for holding bottles with a narrowed neck disclosed in EP 0 367 559 B1 shows a remedy for this disadvantage. The device consists of an elongated fixing part, which can be fixed to the dishwasher basket via a fixing device. The fixing part has a plurality of pairs of clamping parts for holding the bottle. Each pair of clamping parts is suitable for accommodating and clamping the bottle neck. The bottle is inserted vertically and inverted into the corresponding clamping pair of the annular structure. A disadvantage of this embodiment of the fixing device is that there is no separate nozzle for inserting into the bottle in order to clean the built-in bottle. Another disadvantage is that different bottle neck diameters cannot be accommodated by the clamping parts.

[0006] The washing device disclosed in document EP 3 319 499 B1 is considered to be the closest prior art. To this end, it begins to describe a device of this type, which uses a dishwasher in a dishwasher as a carrier. An elongated bottle device is fixed to a dishwashing basket via a clamping element, which extends over the entire width of the dishwashing basket and has a relatively low height, and the clamping element is located at the lower side of the bottle device. The bottle device has a non-rotating spray unit on its upper side, which is provided with a spaced-apart nozzle, which sprays cleaning liquid upward and directly into the corresponding cavity of the bottle. Protrusions are arranged on the left and right sides next to the nozzle. The protrusions prevent the lateral displacement of the bottle, which is placed upside down on the nozzle with its bottle opening. In order to prevent the bottle placed on the nozzle from falling in the dishwashing basket, the bottle is supported laterally by a plurality of crosspieces that can accommodate dishes. In order to be able to deliver cleaning liquid to the bottle washing device, the spray unit is provided with an interface. The interface corresponds to the interface opening in the rear wall when the dishwashing basket is pushed into the dishwasher, wherein the interface opening contains a safety valve. It has proven to be disadvantageous that bottle washing devices are not suitable for holding larger glass bottles and bottles made of plastic and for cleaning inner surfaces without residue.

[0007] All types of bottle washing at home can also be considered as prior art. At home, individual bottles are washed with the aid of a washing brush. For this purpose, there are a wide variety of bottle brushes. Bottle brushes are designed in various ways so that the brush passes through a narrow bottle neck and, on the other hand, is intended to reach and clean the entire bottle interior. However, the disadvantage is mostly that the narrow neck of the bottle only allows the brush to be introduced through the bottle neck. However, after the brush has been opened in the bottle interior, the brush is not of a size suitable for cleaning the entire interior. Summary of the invention

[0008] The object on which the present application is based is to avoid existing disadvantages and to improve upon the prior art.

[0009] The device according to the invention is a bottle rinsing system for a dishwasher, preferably a domestic dishwasher. Private domestic dishwashers are usually manufactured with a capacity of 12 to 14 cutlery sets with a width of 60 cm (European standard EN 1116) or a niche width of 55 cm (Swiss measurement system). The cutlery sets meet the standardized requirements of the European standard EN 50242 and have standardized baskets for the dishes to be washed.

[0010] Therefore, it is necessary to achieve this object: use a device with the dishwasher characteristics shown above and described below in order to achieve the desired cleaning effect in bottles. In principle, dishwashers are used for mechanical cleaning of cooking and eating utensils, cutlery and kitchen utensils, and bottles with narrow necks do not belong to this. According to the Schinner cycle, cleaning is carried out through the interaction of time, mechanical energy, temperature and chemical factors. Rotating nozzles spray or spray a strongly alkaline rinsing solution onto the dishware parts. However, the generated and moving jet does not reach the inside of the bottle with a narrow neck. In order to clean the internal surfaces, the high pH value of the lye, fat-dissolving surfactants and factors such as temperature, action time, pressure and volume flow of the water jet are very important for dissolving dirt. However, the dishwashers known in the prior art cannot meet these prerequisites for bottles or vases, etc. In addition, dishwashers also have a variety of rinse programs, the duration and temperature range of the rinse programs are the same as each other. The rinse programs are divided into a pre-rinse (cold water without detergent) to remove easily removable food residues, a main rinse (temperature approx. 30 to 70°C with detergent) and a rinse cycle (temperature approx. 65 to 85°C). The rinsed items are cleaned in both rinse cycles, while the rinse cycle is used to remove contaminated rinse water and to dry the rinsed items. This also prevents the formation of limescale and water spots. The rinse program is often also suitable for cleaning built-in surfaces such as bottles, vases, etc.

[0011] The object underlying the present invention is to find a solution for cleaning the inner surfaces of cavities, preferably the inner surfaces of bottles with relatively narrow necks, in known dishwashers using existing rinse programs. The solution consists of a bottle rinsing system integrated in the dishwasher basket and described below.

[0012] This object is achieved according to the invention by means of a device having the features of claim 1. Advantageous embodiments are apparent from the associated dependent claims.

[0013] The device according to the invention of a bottle rinsing system consists of a support rail, which has: at least one connecting element for accommodating a holding device for a pipe, wherein the holding device is arranged on a flat surface of a flange of the support rail; the support rail has at least one holding device, at least one pipe, at least one cleaning nozzle and at least one support frame.

[0014] In order to meet the needs of the bottle rinsing system for use at a removable dishwashing basket in a dishwasher, the device is equipped with an elongated carrying rail. The carrying rail has an L-shaped profile, which is formed by a vertical flange and a horizontal flange. The L-shaped profile can be formed by an isosceles profile a=b, preferably by an isosceles profile a<b, wherein a) forms the horizontal flange and b) forms the vertical flange.

[0015] The carrying rail is designed so that it can establish a detachable clamping connection with the cutlery basket, more precisely, on the inner side of the cutlery basket. For this purpose, the vertical flange of the L-shaped profile of the carrying rail has a clamping mechanism at the bottom and along its longitudinal axis. The clamping mechanism includes a plurality of bottom wires of the cutlery basket, which extend transversely to the longitudinal axis of the carrying rail. The horizontal flange of the carrying rail also has a clamping element. The clamping element includes a wire extending transversely to the bottom wire at a certain parallel spacing. The clamping element extends parallel to the longitudinal axis of the carrying rail. According to an embodiment of the cutlery basket, the carrying rail can be arranged on the inner side of the cutlery basket in the longitudinal direction or in the transverse direction. The carrying rail is preferably arranged at the inner bottom in the side area or rear area of ​​the cutlery basket.

[0016] Another advantage of the carrier rail is that the carrier rail also has at least one additional connecting element of different design, preferably three additional connecting elements, which are arranged at a distance from each other at the vertical longitudinal side of the carrier rail. The connecting element of the carrier rail corresponds to the connecting element of the retaining mechanism in order to fix the retaining mechanism at the carrier rail. The carrier rail is an angle profile, which is composed of two flanges spaced 90 degrees apart. The vertical longitudinal side represents the inner side of the vertical flange of the carrier rail. Two of the three connecting elements are respectively located at the free end, and the third connecting element is arranged centrally between the other two connecting elements at the carrier rail when viewed in the longitudinal direction. In a first embodiment, the connecting element can be composed of an opening in the carrier rail, the opening accommodates at least one corresponding plug, which can have different shapes and is arranged at the retaining mechanism. Similarly, in a second embodiment of the carrier rail, a protrusion, for example in the form of a plug, is present instead of the opening, which is inserted into the corresponding opening of the retaining mechanism and thus establishes a mating connection. Therefore, the connecting element is composed of two fixing mechanisms inserted into each other, which establish a connection between the carrier rail and the retaining mechanism. Therefore, other connecting elements, such as screw connections, rivet connections, etc., can also be considered. In a specific embodiment, the connecting element between the carrying rail and the retaining mechanism can also be composed of an adhesive or adhesive connection. Therefore, the connecting element is used to fix the retaining mechanism for the pipeline, wherein the retaining mechanism itself can be composed of a clamping mechanism. In another specific embodiment, the carrying rail can be formed in one piece with one or more retaining mechanisms. The retaining mechanisms formed in one piece with the carrying rail are respectively located at the free ends of the carrying rail. However, this does not involve a retaining mechanism that is provided with two openings and is centrally arranged between the two retaining mechanisms. This means that, in an embodiment, only the retaining mechanism located in the middle, preferably one retaining mechanism, needs to be connected to the carrying rail. In another design, the retaining mechanism that is centrally arranged on the carrying rail is integrated at the carrying rail, and the two retaining mechanisms on the right and left sides of the centrally arranged retaining mechanism are installed at the carrying rail by means of a connecting element.

[0017] This holding mechanism fixed to the support rail advantageously has at least one opening for accommodating a rotatable pipe. This holding mechanism can be constructed similarly to the clamping mechanism known from the prior art for fixing a non-flexible plastic empty pipe. The clamping mechanism for the empty pipe consists of a clamping sleeve. However, the clamping sleeve for the bottle washing system must accommodate the pipe so that the pipe is fastened to the support rail on the one hand and can rotate around its own rotation axis in the opening of the holding mechanism on the other hand. As shown below, the holding mechanism has further tasks to be achieved. Therefore, a creative holding mechanism is needed. According to the present invention, the holding mechanism can also have an interface and / or a valve for the inflow of cleaning liquid.

[0018] The holding mechanism can also be formed by a bearing seat. An element that, for example, accommodates a sliding bearing and can be held in a specific position so that the shaft rotates therein is referred to as a bearing seat. Advantageously, a bearing seat at the support rail can be used as a holding mechanism, and the bearing seat can be accommodated in at least one opening of a rotatable, preferably plastic pipe as provided here according to the present invention. The two bearing seats arranged at the free end of the support rail have openings, which are formed as blind holes. That is to say, the two bearing seats are open on one side and closed on the side opposite to the opening. After being installed at the support rail, the open side of the support block faces each other with the support seat opening, wherein the opening is located on the same center line, and the closed side of the support block points outward along the longitudinal direction of the support rail. According to the present invention, the support seat can also have an interface and / or a valve for the inflow of cleaning liquid. In addition, in summary, it can be implemented that the pipeline T-piece formed by the pipeline is rotatably arranged in the holding mechanism or the support seat, wherein the pipeline T-piece has a branch pipe, and the cleaning nozzle can be detachably connected to the branch pipe.

[0019] The middle support seat arranged between the two outer support seats has a through opening and is also located on the same center line of the blind holes of the other two support seats. In this advantageous arrangement of the support seats and their embodiments, the pipeline is inserted into the borehole. In order to prevent the cleaning liquid from flowing out of the support seats, sealing rings, preferably O-rings, are arranged at the entrance of the borehole respectively, which prevent the cleaning liquid from escaping. In another advantageous embodiment of the support seat with blind holes, the sealing ring can be abandoned because the end of the pipe of the pipeline inserted into the opening of the support seat is closed. This is the case if the interface for the cleaning liquid is arranged centrally at the support seat arranged between the two support seats.

[0020] The middle support seat has another inventive feature. The support seat arranged between the two support seats is characterized in that an interface for the inflow of cleaning liquid is formed at the support seat, wherein the interface can also be formed by a detachable interface coupling. The design of an external holding device or an external support seat can also advantageously form an interface for the inflow of cleaning liquid, wherein the holding device is arranged on the left and right side of the middle support seat on the support rail. Another feature is that the middle support seat with the through opening can have two valves and thus also assume the function of an open or closed valve for the inflow of cleaning liquid.

[0021] The carrier rail according to the invention thus has a number of advantages resulting from the arrangement of the bearing seats on the carrier rail. Advantages arise from the fact that the bearing seats are arranged in a row and on the same center line, but at different spacings, preferably at equidistant spacings. Thus, a plurality of cleaning nozzles can be provided for the bottle rinsing system. Another advantage is that the pipe inserted into the bore of the bearing seat is designed in such a way that it can be rotated by a specific angle, preferably an angle between 0 and 90 degrees.

[0022] According to the invention, in an embodiment of the T-piece, the pipeline is inserted between two opposite bearing seats, whereby the pipeline T-piece becomes rotatable due to the two bearing seats. In this first design, the right bearing seat or the left bearing seat has a connection for the cleaning fluid. In the bearing seat, there is also a valve for the cleaning fluid to flow into the pipeline T-piece, which valve can be opened and closed.

[0023] In another advantageous design, three bearing seats are arranged at the support rail. This means that the three bearing seats arranged at the support rail form two spacings, wherein each spacing is equipped with a pipeline T-piece. In this second design, the interface for the cleaning liquid is located in the middle bearing seat of the three bearing seats. In the middle bearing seat, there are also two valves for the cleaning liquid to flow into the two pipeline T-pieces, which can be opened and closed. One valve regulates the inflow of the cleaning liquid for the pipeline T-piece connected to the left, and the other valve regulates the cleaning liquid for the pipeline T-piece connected to the right. Therefore, the two opposite free ends of the pipeline T-piece are inserted into the corresponding bores of the opposite and spaced bearing seats.

[0024] The pipe T-piece forms a connecting link, which in most cases enables the branch pipe to be connected to an existing connection. The T-piece can be used in different technical fields of use. In the current case, the T-piece for the pipe connection is used as a liquid guiding system. The pipe T-piece is a base element for a bottle rinsing system in a liquid system. In another advantageous design of the carrier rail, the carrier rail can also accommodate four bearing seats, thereby forming three spacings between the bearing seats, and the spacings respectively accommodate the pipe T-piece, thereby obtaining three connecting links or three branch pipes. It can also be considered that: additional bearing seats are also arranged at the carrier rail, thereby increasing the number of bearing seats and thus increasing the number of pipe T-pieces and branch pipes. When the number of pipe T-pieces increases, the number of cleaning nozzles connected thereto also increases. However, the smaller the spacing between the pipe T-pieces becomes, the smaller the spacing between the cleaning nozzles becomes. The elongated carrier rail can extend over the entire length of the dishwasher basket and thus contain multiple cleaning nozzles.

[0025] According to the invention, the pipe T-piece performs several functions. The first function is to serve as a closure for the valve. When the cleaning nozzle is placed horizontally on the bottom wire of the dishwasher basket, the valve is closed. The second function is to let the cleaning liquid pass. When the valve is open, the cleaning liquid is guided through. The valve opens when the cleaning nozzle is aligned within a specific angle from the horizontal to the vertical angle. This angle is determined by the diameter of the bottle to be cleaned and the size of the support frame on which the bottle is placed. The third function is the rotatability of the pipe T-piece within a specific angle range, advantageously between 0 degrees and 90 degrees. The opening and closing of the valve is achieved depending on the rotatability of the pipe T-piece in the support seat. In the horizontal position of the branch of the pipe T-piece, the valve is closed. If the pipe T-piece is turned counterclockwise, the valve opens and the cleaning liquid can flow through the connected cleaning nozzle and clean the interior of the hollow body. Fourth, the branch of the pipe T-piece forms an interface for the cleaning nozzle as a connecting piece.

[0026] In a first embodiment, the interface at the branch of the pipeline T-piece can be formed by a screw connection, and a cleaning nozzle with a corresponding thread can be screwed into the screw connection. In a second advantageous embodiment of the interface, there is an interface coupling at the branch of the pipeline T-piece, preferably a quick-change coupling, into which the cleaning nozzle and its corresponding counterpart can be pushed. There is the feasibility of quickly and simply replacing the cleaning nozzle and, for example, descaling. In a special embodiment of the pipeline T-piece, the interface of the branch is configured so that it has an additional rotating element, which cooperates with the cleaning nozzle. The rotating element is configured so that the cleaning nozzle is rotated by means of a cleaning liquid. Thereby, the cleaning nozzle can rotate around its rotation axis. In particular, the rotation axis of the cleaning nozzle is arranged on the same rotation axis of the rotary joint oriented on the same center line of the branch of the pipeline T-piece and perpendicular to the rotation axis of the pipeline T-piece. Here, in principle, it can be considered that the rotating element and the branch of the pipeline T-piece are jointly formed at the detachable interface position at the cleaning nozzle to which it belongs. Due to the rotating element, the cleaning lance forms a rotating element.

[0027] The cleaning nozzle according to the present invention has many advantages. The cleaning nozzle is formed by a hollow body, preferably a tubular body, which is closed at its tapered end and has an opening for conveying cleaning liquid at the other end. Advantageously, the opening can be formed with an interface coupling. In a particularly advantageous design of the interface coupling, a rotating element is also provided, whereby the cleaning nozzle becomes a rotating body. In addition, the tubular body has openings distributed on its circumference or on its side surface and on the length of the tubular body. The openings can be distributed symmetrically on the circumference and in an equidistant manner on the length. The opening is configured as a pointed nozzle for guiding the cleaning liquid through, so as to wet and then clean the inner surface of the cavity. The diameter of the tubular body or the cleaning nozzle is approximately adapted to the diameter of the bottleneck. The diameter of the cleaning gun is smaller than the bottleneck diameter by a specific amount so that the cleaning liquid can flow out of the bottle interior space without hindrance.

[0028] In order to use the cleaning nozzle arranged in the inner space of the cutlery basket, the cleaning nozzle can be lifted from the flat static position. In the static position, the cleaning nozzle is placed on the bottom wire of the cutlery basket, and the valve in the holding mechanism or the support seat is closed so that no cleaning liquid can flow through the cleaning nozzle. In the static position, the cutlery basket can be used for normal washing of dishes. If one or more cleaning nozzles are to be used to wash bottles, the cleaning nozzle is raised to a specific angle between 0 and 90 degrees, wherein the pipeline T-piece opens the valve in the holding mechanism or the support seat. Now, the hollow body (preferably a bottle) is turned upside down on the cleaning nozzle paper with its bottleneck, wherein the other end of the bottle, more precisely the bottle belly, is placed on the opened support frame. The support frame is foldable and can be folded upward from the basic position and folded down again to the basic position. In the basic position, the support frame is placed on the bottom wire of the cutlery basket. After the cutlery basket is pushed into the dishwasher, the cleaning process of the bottle rinsing system can be started. After the cleaning process, the cutlery basket is pulled out again and one or more bottles are taken out of the cleaning nozzle. The cleaning lance is now lowered again. By lowering the cleaning lance into the rest position, the valve in the holding mechanism or the support is closed again. When the bottle rinsing system is in use, more precisely when the device is loaded with bottles, the free area in the dishwashing basket can also be filled with dishes and used for washing.

[0036] like Figures 1 to 5 As shown in the perspective view in FIG. 1 , an embodiment of the bottle rinsing system according to the invention comprises a device 1 for holding and mechanically cleaning the inner surface 33 of a bottle 29, wherein the bottle 29 is arranged in a pull-out lower dishwashing basket 17 of a dishwasher. The bottle 29 is placed upside down with its neck 37 on the cleaning nozzles 9.1, 9.2, wherein the neck 37 is placed on a support frame 38 and the bottle belly 41 is placed on the support frames 10.1, 10.2 respectively (see FIG. 1 ). Figure 5 The cleaning nozzles 9.1, 9.2 are rotatably connected to the pipes 8.1, 8.2, which are supported in the holding mechanisms 3.1, 3.2, 3.3. The holding mechanisms 3.1, 3.2, 3.3 are fixed to the support rail 2, wherein the support rail 2 has clamping elements 5.1, 5.2, 5.3, 6 (see Figure 2 ), the clamping element is connected to the wires 15, 16 of the dish rack 17 on the inner side 19 of the extendable cutlery basket 17. One wire 15 forms the bottom wire transversely to the insertion direction 54, and the other wire 16 forms the bottom wire longitudinally to the insertion direction 54. The inflow of cleaning liquid takes place via the interface 22 arranged at the holding device 3.3. From the interface 22, the cleaning liquid then flows through at least one conduit 8.1, 8.2 and then through at least one cleaning nozzle 9.1, 9.2, which distributes the cleaning liquid with its nozzle 32 in the interior of the bottle 29 and cleans the internal surface 33. The cleaning liquid then flows back into the circuit of the dishwasher from the opening in the neck 37 of the bottle 29 arranged obliquely on the support frame 10.1.

[0037] Bottle rinsing system Figure 1The device 1 shown in the perspective view in FIG. 1 is essentially composed of a device 1 for holding and cleaning an inner surface 33 of two bottles 29, wherein the device 1 is equipped with bottles 29. The device 1 is arranged for use at a pull-out cutlery basket 17. For the sake of clarity, the rotating spray arm arranged below the cutlery basket 17 is not shown. The cutlery washing basket 17 is used to accommodate the rinsed items and, according to the invention, its functionality is extended by the device. The device 1 is composed of an elongated support rail 2. The support rail 2 has a longitudinal axis 35 (see FIG. 2 ). Figure 2 ), the longitudinal axis is spaced parallel to the longitudinal side 24 of the cutlery basket 17 and extends in the direction of the insertion direction 54. This advantageous arrangement of the support rail 2 on the cutlery basket 17 is realized for the connection 22 for the cleaning liquid: it corresponds to the docking opening on the rear wall of the tank of the dishwasher (not shown). The elongated support rail 2 is provided with clamping elements 15.1, 5.2, 5.3 on the lower side 36 along the longitudinal axis 35 (for the sake of clarity in the illustration). Figure 2 The clamping elements 1 5.1, 5.2, 5.3 comprise a bottom wire 15 arranged transversely to the insertion direction 54 of the cutlery basket 17, so as to realize a detachable clamping connection 18 on the inner side 19 of the cutlery basket 17. In addition, the carrying rail 2 has a plurality of retaining means 3.1, 3.2, 3.3 (see also Figure 3 ) of multiple connecting elements 7.1, 7.2, 7.3 (see Figure 2 ), the holding means is the carrier of the two pipes 8.1, 8.2. The holding means 3.1, 3.2, 3.3 of the pipes 8.1, 8.2 are arranged at the flat surface of the vertical flange 14 of the L-shaped profile 11 of the carrier rail 2 (see Figure 2 and Figure 3 The two pipes 8.1 and 8.2 are respectively formed by pipe T-pieces 25.1 and 25.2 (see Figure 3 ). Clean the nozzles 9.1 and 9.2 (see Figure 3 and Figure 4 ) are arranged at the branches 26.1, 26.2 of the pipe T-pieces 25.1, 25.2, respectively. The cleaning nozzle 9.1 is in a horizontal rest position 39 and is placed on a bottom wire 16 extending transversely to the insertion direction 54, wherein the bottom wire 16 is U-shaped at the placement position of the cleaning nozzle 9.1 in the direction of the bottom tank of the dishwasher to accommodate the lowered cleaning nozzle 9.1. In the rest position 39, the valve 51.2 in the middle holding device 3.2 is closed, and the other cleaning nozzle 9.2 is in the working position 40. In the working position 40, the cleaning nozzle 9.2 is raised counterclockwise by a specific angle 52 (see also Figure 3), and the valve 51.1 in the holding device 3.3 with the cleaning interface 22 is opened. In the position bent from the horizontal bottom wires 15, 16, i.e. in the working position 40, the bottle 29 is turned upside down on the cleaning nozzle 9.2, wherein the cleaning nozzle 9.2 extends into the interior of the bottle 29 through the bottleneck 37. In order to be able to position the bottle 29 to be cleaned in the working position 40, the bottleneck 37 is placed on a support frame 38, which prevents the bottle 29 from sliding relative to the holding device 3.2, 3.3. The pin 78 arranged in the branch pipe 26.1, 26.2 of the pipeline T-piece 25.1, 25.2 can also be used as a base 13 (see Figure 4 ), used to replace the support frame 38. At the same time, the bottle belly 41 of the bottle 29 is placed on the upwardly folded support frame 10.1 (see Figure 5 ), the support frame can have different shapes.

[0038] exist Figure 2 Shows that you can Figure 1 Schematic diagram of a support rail 2 of an apparatus 1 formed of an angle profile, the support rail being formed by two flanges 12, 14 bent 90 degrees. Figure 1 The reference numerals shown in . The angle profile of the carrying rail 2 forms an L-shaped profile 11, which is composed of a vertical flange 14 and a horizontal flange 12. The horizontal flange 12 has a plurality of recesses 42, 43, whereby three connecting pieces 44, 45, 46 are formed in the horizontal flange 12. Two of the three connecting pieces 44, 46 are respectively located near the free ends 23.1, 23.2 of the horizontal flange 12 of the carrying rail 2, and the third connecting piece 45 is centrally located between the other two connecting pieces 44, 46 at the carrying rail 2, as viewed in the longitudinal direction 35. The two outer connecting pieces 44, 46 have openings 47, 48, respectively, which extend in the connecting pieces 44, 46 and are perpendicular to the vertical flange 14. The openings 47, 48 accommodate a wire, which forms a support frame 38 for supporting the neck 37 of the bottle 29 (see Figure 1 ). In addition, the horizontal flange 12 has a continuous opening 49 in the longitudinal direction of the longitudinal axis 35, which is arranged in the corner region of the vertical flange 14 relative to the horizontal flange 12. The opening 49 forms a longitudinal slot, which is designed as a clamping element II 6. The clamping element II 6 comprises the upper wire 16 of the cutlery basket 17 (see Figure 1 ). The elongated support rail 2 also has clamping elements 1 5.1, 5.2, 5.3 on the underside 36 along the longitudinal axis 35. The clamping elements 1 5.1, 5.2, 5.3 comprise the bottom wire 15 of the cutlery basket 17 and form with the bottom wire 15 a detachable clamping connection 18 on the inner side of the cutlery basket 17 (see Figure 1). The clamping elements 1 5.1, 5.2, 5.3 are arranged in the vertical flange 14 of the support rail 2. The spacing between the clamping elements 1 5.1, 5.2, 5.3 is determined by the spacing of the bottom wires 15 of the cutlery basket 17 extending transversely to the insertion direction 54.

[0039] Furthermore, further connecting elements 7.1, 7.2, 7.3 are arranged on the inner side 20 along the vertical flange 14 of the carrying rail 2. The connecting elements 7.1, 7.2, 7.3 are located below the horizontal connecting pieces 44, 45, 46, respectively. In a first embodiment, the connecting elements 7.1, 7.2, 7.3 can be formed by at least one opening 50 in the carrying rail 2, which corresponds to a corresponding hook (not shown) at the holding means 3.1, 3.2, 3.3. In an alternative embodiment, instead of the opening 50, there is a small protrusion, for example in the form of a hook (not shown), which is inserted into a corresponding opening in the holding means 3.1, 3.2, 3.3. Further different connecting elements 7.1, 7.2, 7.3 between the carrying rail 2 and the holding means 3.1, 3.2, 3.3 are conceivable.

[0040] Figure 3 A schematic diagram of a specific embodiment of a carrying rail 2 and three holding mechanisms 3.1, 3.2, 3.3 arranged thereon according to the present invention is shown. Figure 2 The holding means 3.1, 3.2, 3.3 are configured as bearing seats 4.1, 4.2, 4.3. The bearing seats 4.1, 4.2, 4.3 are connected via connecting elements 7.1, 7.2, 7.3 (see Figure 2 ) is connected to the support rail 2. The support seats 4.1, 4.2, 4.3 are used to accommodate the pipes 8.1, 8.2. The pipes 8.1, 8.2 are configured as pipe T-pieces 25.1, 25.2. Branch pipes 26.1, 26.2 are respectively configured at the pipe T-pieces 25.1, 25.2, and cleaning nozzles 9.1, 9.2 are respectively arranged at the branch pipes (see Figure 1 and Figure 4). The pipe T-pieces 25.1, 25.2 are used to allow the cleaning liquid to flow through. Therefore, there are two integrated pipe T-pieces 25.1, 25.2 between the three bearing seats 4.1, 4.2, 4.3 arranged at the inner side 20 of the L-shaped profile 11 of the support rail 2 in the immediate vicinity of the connecting pieces 44, 45, 46. Depending on the angular position 52 of the branch pipes 26.1, 26.2 and the pipe T-pieces 25.1, 25.2 between 0 and 90 degrees, preferably between 0 and 45 degrees, the valves 51.1, 51.2 in the bearing seats 4.2, 4.3 are opened or closed. The valves 51.1, 51.2 are opened and closed by rotating the pipe T-pieces 25.1, 25.2 about the axis of rotation 21. If the pipe T-pieces 25.1, 25.2 are rotated counterclockwise, the valves 51.1, 51.2 are open. If the pipeline T-pieces 25.1, 25.2 are rotated clockwise, the valves 51.1, 51.2 are closed. The first valve 51.1 is located in the support seat 4.3, which has a connection 22 for the cleaning liquid. The branch pipe 26.2 of the pipeline T-piece 25.2 is located in an angular range of about 45 degrees, which corresponds to the working position 40 of the connected cleaning nozzle 9.2. In the working position 40, the valve 51.1 in the holding mechanism 3.3 is open. The other branch pipe 26.1 of the pipeline T-piece 25.1 is located in an angular range of 0 degrees, which corresponds to the static position 39 of the connected cleaning nozzle 9.1. The valve 51.2 integrated in the intermediate support seat 4.2 is closed. In another embodiment of the intermediate support seat 4.2, the valve 51.2 is operated manually or the like, and then the operating element 53 is rotated to open or close the valve 51.2, thereby regulating the flow of cleaning liquid to the cleaning nozzle 9.1. The cleaning nozzles 9.1, 9.2 are closed on the center line 74 of the branch pipes 26.1, 26.2, see below. Figure 4 .

[0041] Figure 4 A schematic diagram of a cleaning nozzle 9.1 with a rotating element 28 and an interface coupling 27 is shown, which is arranged at the branch 26.1 of the pipeline T-piece 25.1. At the branch 26.1, a pin 78 arranged transversely to the branch 26.1 is located near the free end 59. The pin 78 forms a base 13 for supporting the neck 37 of the bottle 29. In this case, a similar method is used. Figure 1 and 3The reference numerals shown in . The pipeline T-piece 25.1 has a branch pipe 26.1, and in a first embodiment, the cleaning nozzle 9.1 is detachably connected to the branch pipe. The branch pipe 26.1 forms a connecting piece with the cleaning nozzle 9.1, and therefore has an internal thread 57 for connecting the cleaning nozzle 9.1 at the free end 59. In order to be detachable, the cleaning nozzle 9.1 is provided with an external thread 58 at one of the two free ends 60, and the external thread corresponds to the internal thread 57 in the branch pipe 26.1 of the pipeline T-piece 25.1. The other free end 55 forms the tip of the cleaning nozzle 9.1. In the first embodiment, the interface at the branch pipe 26.1 of the pipeline T-piece 25.1 is composed of a spiral connection provided with a sealing ring 61. In the second embodiment, the connection between the branch pipe 26.1 and the cleaning nozzle 9.1 is composed of a quickly detachable interface connector 27, and the interface connector is composed of a plug-in connector. The plug-in coupling is a secure connection which can be established in a short time by means of simple manipulation and can be separated just as quickly. The interface coupling 27 is a through-coupling and a (plug-in) sleeve with a free passage; neither component has a valve. The plug-in coupling 27 is used to connect the cleaning lance 9.1 to the branch pipe 26.1 in a quickly detachable manner. The plug-in coupling closes and locks automatically by a linear axial displacement.

[0042] In a third embodiment, the connection between the branch pipe 26.1 and the cleaning lance 9.1 is designed so that an additional rotating element 28 is connected to the quickly removable interface coupling 27, which cooperates with the cleaning lance 9.1. The rotating element 28 is designed so that the cleaning lance 9.1 causes a rotation 62 by means of the cleaning liquid flowing through. The cleaning lance 9.1 can thereby rotate about its axis of rotation 63. Advantageously, instead of the rotation 62, an oscillating movement of the cleaning lance 9.1 can also be performed. In particular, the axis of rotation 63 of the cleaning lance 9.1 is arranged on the same axis of rotation of the rotating element 28. The axis of rotation of the rotating element 28 in turn extends along the center line 74 of the branch pipe 26.1 of the pipeline T-piece 25.1. The center line 74 is perpendicular to the axis of rotation 21 of the pipeline T-piece 25.1. Due to the rotating element 28, the cleaning lance 9.1 forms a rotating element.

[0043] The cleaning nozzle 9.1 is formed by a hollow body, preferably a tubular body, which is closed at its tapered end 55 and has an opening 56 for conveying cleaning liquid at the other end. The branch pipe 26.1 or the interface coupling 27 or the rotating element 28 is connected to the opening 56. In addition, the tubular body has openings 31 on its circumference or on its side surface 30. The openings 31 are distributed over the length of the tubular body. The openings 31 can be distributed symmetrically on the circumference and / or at equidistant intervals along the length direction. The openings 31 serve as a pointed nozzle 32, which is used to pass the cleaning liquid through to wet the inner surface 33 of the cavity of the bottle 29 (see Figure 1), and then clean it. The diameter 64 of the tubular body or cleaning nozzle 9.1 is approximately adapted to the diameter of the bottleneck 37. The diameter 64 of the cleaning nozzle 9.1 is smaller than the diameter of the bottleneck 37 by a certain amount so that the cleaning liquid can flow out of the inner space of the bottle 29 without hindrance. The length 75 of the cleaning nozzle 9.1 is approximately adapted to the height of the bottle 29. Because there are bottles 29 of different sizes, there are cleaning nozzles 9.1 of different lengths accordingly. However, the free end 55 of the cleaning nozzle 9.1 is several centimeters away from the bottom 76 of the bottle. Due to the arrangement of the nozzle 32 and the obliquely arranged opening 31 at the tapered end 55, the bottom 76 of the bottle (see Figure 1 ) is optimally cleaned of contaminants. The interface coupling 27 enables quick and simple replacement of the cleaning nozzles 9.1, 9.2.

[0044] Figure 5 Shown for supporting Figure 1 Schematic diagram of two supports 10.1, 10.2 for bottles 29 shown in FIG. The supports 10.1, 10.2 are formed by the same wire 65 as the cutlery basket 17. The supports 10.1, 10.2 are fixed to the inner side 19 of the cutlery basket 17 at the bottom wire 15 (see FIG. Figure 1 ). In order to fix the support frames 10.1, 10.2 to the bottom wire 15 of the cutlery basket 17, clamping means 67.1, 67.2, 67.3, 67.4 are arranged at the free ends 66.1, 66.2, 66.3, 66.4 of the wire 65. The clamping means 67.1, 67.2, 67.3, 67.4 are inserted around the bottom wire 15 of the cutlery basket 17. In addition, the wire 65 of the support frames 10.1, 10.2 is rotatably fixed in the clamping means 67.1, 67.2, 67.3, 67.4. Due to the rotatability of the support frames 10.1, 10.2, the support frames can be folded upwards from the basic position 68 into the supporting position 69 and folded downwards again. Between the basic position 68 and the support position 69 there is an angle 34 between 80 and 120 degrees, advantageously 90 degrees, wherein the support frames 10.1, 10.2 are releasably locked in the clamping mechanisms 67.1, 67.2, 67.3, 67.4 in the support position 69. In the folded-away support position 69 of the support frame 10.1, the bottle belly 41 of the bottle 29 can be placed on the crossbars 70.1, 70.2, as shown in FIG. Figure 1As shown. As shown, the crossbars 70.1, 70.2 are composed of horizontally arranged wires, which have two free ends and a length of between about 3 cm and 10 cm, preferably 10 cm. The crossbars 70.1, 70.2 can also have a curved shape that is approximately the radius of the bottle belly 41, thereby achieving a stable posture of the bottle 29 (not shown). In the basic position 68, the support frame 10.2 is folded down and placed on the bottom wire 15 of the cutlery basket 17. In the basic position 68, the cleaning nozzle 9.1 can be placed on the flat support frame 10.2 and then in the static position 39. The support frames 10.1, 10.2 have a shape that is approximately a rectangular function. The horizontal parts 72.1, 72.2, 72.3, 72.4 of the wire 65 are arranged rotatably around the center line 71 in the clamping mechanism 67.1, 67.2, 67.3, 67.4. The parts 73.1, 73.2, 73.3, 73.4 merge in one piece into the connected crossbars 70.1, 70.2, which are formed in one piece at the horizontal wire 65 and are bent by 90 degrees. The crossbars 70.1, 70.2 are spaced apart parallel to the center line 71 of the horizontal parts 72.1, 72.2, 72.3, 72.4 of the wire 65. The support frames 10.1, 10.2 are characterized in that the vertical parts 73.1, 73.2, 73.3, 73.4 of the wire 65 do not merge straight or vertically into the crossbars 70.1, 70.2, but are bent at a specific radius 77.1, 77.2, 77.3, 77.4, so that the two crossbars 70.1, 70.2 are not located in the same plane as the horizontal and vertical wires 65. The plane of the crossbars 70.1, 70.2 is spaced a certain distance from the plane of the horizontal and vertical wires 65. This distance corresponds approximately to the diameter 64 of the cleaning nozzle 9.1. Thus, in the basic position 68 of the support frame 10.2, the crossbar 70.2 is located approximately below the bottom wire 15 of the cutlery basket 17 and serves as a support for the cleaning nozzle 9.1 lying flat, i.e. in the rest position 39 (see Figure 1 ).
