Description

[Technical Field]

[0001] The present invention relates to a cleaning channel device for a basin, in particular a sink or washbasin, with a profile assembly according to the preamble of claim 1 .

[0002] The invention further relates to a basin, in particular a sink or washbasin, having a cleaning channel device. [Background technology]

[0003] Numerous embodiments of basins are known from the prior art, in particular sinks for use in kitchens and washstands for body care, with many variations. Such basins are used, for example, in the domestic, industrial and medical sectors.

[0004] In most cases, hygiene is of paramount importance, especially the sterility and cleanliness of the bath, which must therefore be cleaned regularly and thoroughly.

[0005] Most sinks and basins have a water inlet that is fitted with a fitting to provide a central water flow, but a central water flow is not conducive to completely and thoroughly cleaning the inside of the basin.

[0006] To aid in cleaning, fittings with flexible hoses that can be extended or retracted are known. However, they are relatively expensive to manufacture and may require repair. Furthermore, since the appearance of a bath (especially for home use) is often important, flexible fittings can limit the flexibility of the design of the bath and fittings.

[0007] To facilitate cleaning of the tub, Patent Document 1 proposes a tub whose upper tub rim is designed to dispense additional amounts of water at least in certain areas. For this purpose, an inner receiving area with a downwardly open gap is formed in the upper tub rim, in which a surrounding annular water dispenser in the form of a pipe is arranged. On its circumferential surface, the water dispenser has multiple nozzles from which a large amount of water can be dispensed.

[0008] A similar vessel is also disclosed in US Pat. No. 5,623,999, which proposes that the main supply lines for the vessel fittings run annularly around the upper vessel rim and are individually perforated.

[0009] In this way, the inner wall or the side wall of the tank can be selectively cleaned, which is intended to reduce the effort and frequency of manual cleaning.

[0010] However, known water-dispensing devices in this respect have proven only conditionally suitable for cleaning tubs, since the water is discharged in the form of a nozzle at a specific point, resulting in a very uneven flow along the tub sidewall. As a result, uniform and thorough cleaning is not guaranteed. The uneven distribution of water means that additional visible stains, such as limescale, may eventually appear along the tub sidewall.

[0011] Due to these drawbacks, this type of bath has not yet been fully implemented to date - despite the high need for hygiene and cleanliness - and this is where the present invention comes in. [Prior art documents] [Patent documents]

[0012] [Patent Document 1] DE 10 2010 021 541 A1 [Patent Document 2] DE 1 934 095 U Summary of the Invention [Problem to be solved by the invention]

[0013] In view of the known prior art, it is an object of the present invention to provide a cleaning channel arrangement to allow improved cleaning of a vessel, or at least to assist in cleaning of the vessel.

[0014] The present invention is also based on the object of providing an improved bath, preferably a self-cleaning bath, or at least a bath that is easy to clean. [Means for solving the problem]

[0015] The object is achieved by a cleaning channel device having the features set forth in claim 1. With respect to the bath, the object is Claim 24 This is achieved by the following features:

[0016] The dependent claims and features set forth below relate to advantageous embodiments and variants of the invention.

[0017] Provided is a bath cleaning flow path apparatus that includes a profile assembly having an interface or multiple interfaces for supplying liquid to a distribution line of the profile assembly and having a discharge area for dispensing liquid.

[0018] The interface may in particular be a port and / or opening for a liquid supply line.

[0019] The proposed cleaning channel device is particularly suitable for use in a sink or washbasin. In principle, however, the cleaning channel device can be suitable for any desired vessel for rinsing or cleaning. For example, the vessel may be in the form of a bathtub, shower tray, hair washing station or other vessel, but in particular a vessel for washing body parts, plants (plant parts) and / or objects.

[0020] The liquid is preferably water (especially drinking water or tap water), optionally containing additional materials or additives. In principle, any desired liquid suitable for rinsing or cleaning the bath can also be provided, for example a specially prepared cleaning liquid.

[0021] Preferably, the same liquid is supplied to the cleaning channel device as is used in conventional operation of the bath, optionally containing the additional materials or additives mentioned above.

[0022] According to the invention, it is provided that the profile assembly comprises a flow channel extending along a flow channel course from a distribution line to a discharge area, the distribution line, the flow channel and the discharge area extending through the profile assembly along the longitudinal axis of the profile assembly.

[0023] The inventor has realised that when the aforementioned flow path is formed between the distribution line and the discharge area, liquid is discharged from the cleaning flow path device in a manner that is particularly suitable for cleaning or rinsing the tank.

[0024] In contrast to known "self-cleaning" baths, in which water is dispensed directly from the dispensing line through separate nozzles or holes, the flow channels allow for a more uniform laminar flow, resulting in a uniform wetting of the interior of the bath. In this context, it has been shown that the uniform distribution of liquid during bath cleaning contributes substantially to the sterility and overall cleanliness of the bath.

[0025] In one refinement of the invention, it can be provided that the interface for supplying the liquid comprises an opening in a side wall of the profile assembly extending along the longitudinal axis.

[0026] The interface may include, for example, a liquid supply line (e.g., a rigid or flexible pipe), a portion of the liquid supply line, and / or a coupling for connecting the liquid supply line as a whole to the profile assembly.

[0027] In principle, any number of interfaces may be provided, for example exactly one interface, two interfaces, three interfaces, four interfaces or even more interfaces, distributed (e.g. evenly or equidistantly) along the longitudinal axis of the profile assembly.

[0028] However, preferably only one interface is provided, which allows for easy connection of the cleaning channel device to existing sanitary equipment.

[0029] The distribution lines of the profile assembly can advantageously contribute to a uniform distribution of liquid along the longitudinal axis of the profile assembly or within the cleaning channel arrangement.

[0030] In one refinement of the invention, it can be provided that the channel courses are aligned perpendicular to the longitudinal axis of the profile assembly.

[0031] It should be noted that the longitudinal axis of the profile assembly must not have a straight, i.e. linear, course, but preferably has a curved course or at least a curved portion, in particular to follow the course of the side wall of the tank.

[0032] The channel course also preferably does not follow a straight, i.e. rectilinear, course but has at least curved portions, e.g. bends not yet described below, and thus the channel course can preferably form at least one loop (preferably several loops).

[0033] According to one refinement of the invention, it can be provided that the distribution line has a distribution channel diameter (or distribution channel width) that is larger than the maximum channel diameter (or maximum channel width) of the channel.

[0034] Insofar as "diameter" is mentioned in this application, it can in principle mean the diameter of a circular or at least approximately circular channel / line. However, it can also mean the height and / or width of a channel / line having any desired cross section, for example a rectangular cross section. The term "diameter" should therefore not be explicitly understood to mean a circular cross section.

[0035] The fact that the discharge area has a larger flow path diameter, i.e. a larger flow path width, than the flow paths can result in improved distribution of the liquid along the longitudinal axis of the profile assembly: the distribution lines can thereby receive a relatively large amount of liquid and can therefore act as a buffer or reservoir.

[0036] In one refinement of the invention, it can be provided that the distribution line merges into the flow path along a cross-sectional constriction.

[0037] Preferably, a uniform cross-sectional constriction, in particular a linear cross-sectional constriction, can be provided, which can substantially prevent turbulence when the liquid is dispensed.

[0038] In an advantageous refinement of the invention, the distribution line may comprise a distribution element arranged in the region of at least one interface, provided for directing the liquid supplied through the interface through the distribution line in at least two different directions (for example, in opposite directions along the longitudinal axis of the profile assembly).

[0039] This allows for a more uniform distribution of the liquid within the cleaning channel arrangement, and in particular for the occurrence of unfavorable turbulence or vortices to be avoided or at least reduced.

[0040] In principle, an individual interface can also consist of several distribution elements. If several interfaces for supplying liquid are provided, it is preferable to assign at least one dedicated distribution element to each interface.

[0041] The distribution element may be located within the interface or fixed to the interface, but the distribution element may also be located within the distribution line adjacent to the interface.

[0042] According to one refinement of the invention, it can be provided in particular that the distribution element is arranged on the inner wall of the distribution line, opposite the interface in the feed direction of the liquid.

[0043] The distribution element may be configured with a tip or tapered edge aligned in the direction of the interface. The distribution element preferably has a wedge shape with a straight or concavely curved wedge profile. Pyramidal distribution elements may also be provided.

[0044] In one refinement of the invention, it can be provided that the discharge area is in the form of a discharge slot extending along the longitudinal axis of the profile assembly.

[0045] In particular, a continuous discharge slot extending along the longitudinal axis of the profile assembly can distribute the liquid in the tank particularly evenly, but where appropriate, it is also possible to provide a plurality of non-continuous discharge areas, in particular discharge slots, e.g., one discharge area for each side wall of the tank.

[0046] The discharge slot preferably has a discharge diameter or width that is smaller than the minimum flow path diameter / minimum flow path width of the flow path.

[0047] The discharge diameter or width is smaller than the flow path diameter / width, so the discharge area forms a kind of elongated nozzle. The discharge amount and flow velocity of the discharged liquid discharged through the discharge area can be set by the discharge diameter or width.

[0048] In an advantageous refinement of the invention, it can be provided that the outlet diameter or outlet width is approximately or exactly 0.1 mm to 2.0 mm, preferably 0.3 mm to 1.5 mm, particularly preferably 0.5 mm to 1.0 mm, for example 0.8 mm.

[0049] The above ranges have proven to be particularly suitable and allow for specific outlet diameters or widths, which can preferably be determined depending on the pressure used to supply the liquid (in particular with regard to the pressure in the liquid supply line). The above values ​​are particularly advantageously suitable for use at conventional domestic mains pressures of about 3-4 bar.

[0050] In one refinement of the invention, it can be provided that the discharge area comprises an extensible diaphragm, for example a rubber lip.

[0051] The elastic diaphragm is preferably designed to close the ejection area when no liquid is being ejected from the ejection area.

[0052] The elastic diaphragm can optionally further improve hygiene of the cleaning channel device, as it can prevent dirt and / or bacteria from entering the discharge area.

[0053] In an advantageous refinement of the invention, it can be provided that the flow channel forms at least one bend along its course, preferably at least two bends, particularly preferably at least three bends. The flow channel preferably has a looped course.

[0054] Surprisingly, it has been found that by using in particular bends or looped courses of channels it is possible to create a uniform laminar flow that is particularly suitable for cleaning tanks.

[0055] The looped course or bend(s) may further provide a siphon-like flow path, thereby simultaneously providing an odor trap and / or preventing the ingress of dirt or bacteria into the cleaning flow path device.

[0056] In an advantageous refinement of the invention, it can be provided that the flow channel has a smaller cross section along the bend.

[0057] This allows the flow behavior of the liquid to be further optimized.

[0058] The cross section of the flow channel along the bend preferably corresponds to the above-mentioned "minimum flow channel diameter" or "minimum flow channel width" of the flow channel. The cross section of the flow channel along the (generally) linear or straight portion between the bends may preferably correspond to the above-mentioned "maximum flow channel diameter" or "maximum flow channel width."

[0059] In an advantageous preferred refinement of the invention, it can be provided that the distribution lines, the flow passages and the discharge area extend over the same length along the longitudinal axis of the profile assembly.

[0060] However, it may alternatively be provided that the distribution lines, the flow paths and the discharge area do not extend over the same length along the longitudinal axis of the profile assembly, for example that the discharge area extends only over one or more small areas along the longitudinal axis of the profile assembly.

[0061] In one refinement of the invention, it can be provided that the profile assembly has an essentially closed or at least substantially closed course along the longitudinal axis.

[0062] The profile assembly preferably forms a completely closed ring or is completely closed around its periphery, so that the entire periphery of the tub can be cleaned.

[0063] According to one refinement of the invention, it can be provided that the profile assembly has a one-piece or multi-piece form.

[0064] The decision as to whether the profile assembly has a one-piece or multi-piece form can be made in view of, among other things, the manufacturing process, the starting materials of the bath, and the starting materials of the cleaning channel device. Generally, a multi-piece configuration of the profile assembly is preferred for the manufacturing process.

[0065] The profile assembly may have the form of one piece, especially if the cleaning channel arrangement is integrally formed with the basin.

[0066] In an advantageous refinement of the invention, it can be provided that the profile assembly comprises a first profile part and a second profile part, which, when connected to one another, form the discharge area, the flow path and the distribution line (if necessary together with the reservoir).

[0067] In principle, it is also possible to provide further profile parts, for example a third, fourth or even more profile parts, but the construction of a multi-part profile assembly consisting of exactly two profile parts has proven to be particularly suitable for achieving the optimum between economical production and easy installation.

[0068] It may also be provided that the tank or a component of the tank, for example one or more inner walls or side walls of the tank, form part of a (multi-part) profile assembly, for example the discharge area may be formed from a profile part of the profile assembly and a side wall of the tank.

[0069] In an advantageous refinement of the invention, it may be provided that the discharge area, the flow passages and / or the distribution lines are provided with ribs extending between their respective side walls.

[0070] The ribs preferably extend at least in certain parts along the channel course, on the one hand making it possible to regulate the flow of liquid through the profile assembly and on the other hand making it possible to improve the stability of the profile assembly or of the cleaning channel arrangement.

[0071] In an advantageous refinement, it can be provided that the cleaning channel arrangement comprises at least one supply device for supplying an additive to the liquid.

[0072] The additives may be, for example, cleaning substances, such as rinse aids, sanitizing agents, disinfectants and / or descalers, which can improve the functionality of the rinsing of the bath by the cleaning channel device, for example by increasing the cleaning action of the rinsing.

[0073] According to one refinement of the invention, it can be provided that the supply device comprises a reservoir for supplying the additive.

[0074] The reservoir is preferably manually fillable or can be fed from a supply line.

[0075] In an advantageous refinement of the invention, it can be provided that the supply device comprises a conveying device, in particular a pump and / or a venturi nozzle, for conveying and metering the additive.

[0076] The pump may be an electric pump and / or a mechanical pump, for example a foot operated pump.

[0077] The supply device may further comprise electrical and / or mechanical valves to meter the additive as required or to interrupt the supply as required.

[0078] The pumps, valves and, if necessary, the venturi nozzles may be mechanically and / or electronically actuated. Optionally, automated open-loop or closed-loop control may be provided, although purely manual operation is also possible.

[0079] The cleaning channel arrangement may also be provided with a transport unit, in particular a pump, for transporting and / or metering liquid, which may be supplied to the cleaning channel arrangement from a reservoir or liquid store, together with or separately from the liquid for the purposes of conventional use of the bath.

[0080] As long as the reservoir for the additive or the reservoir for the liquid or the liquid storage is located at an elevated position, it is possible to optionally omit the respective pump.

[0081] In an advantageous refinement of the invention, it can be provided that the cleaning channel device is in the form of an integral part of the bath or an insert into the bath.

[0082] According to one refinement of the invention, it can be provided that the profile assembly is provided with an antibacterial coating in certain areas or on the entire surface, preferably affecting the interface, the ejection area and / or the flow path. The antibacterial coating can be, for example, a nanosilver coating.

[0083] In this way, even if the cleaning channel device or tank is not used for a relatively long period of time, the formation of biofilms can be prevented and a sterile state can be ensured.

[0084] In one refinement of the invention, it may be provided that the cleaning channel arrangement comprises a control device configured to control and / or monitor the ejection of liquid from the ejection area, preferably in response to a user input.

[0085] The controller may be communicatively connected (wired and / or wirelessly) to electronic components of the cleaning flow path device, such as pumps, other actuators, sensors, radiation sources as described below, discharge devices as described below, or other devices.

[0086] The control device may include a user interface to allow user input from a user of the cleaning flow device or bath and / or to allow status and measurement readings. The user interface may include a display device, such as a screen, and / or an input device, such as one or more push buttons. Any wireless standard may be used, in particular Bluetooth, WLAN, Zigbee, GSM, or another wireless standard, although a wireless user interface, in particular within the ISM band, is preferably provided. The user interface may constitute a web application and / or an application on a mobile terminal ("app").

[0087] The control device may be equipped with a data interface, via which the control device is connected to a database and optionally to an external computer unit. In particular, the data interface may provide an internet connection, so that the control device can be connected to, for example, a cloud system.

[0088] The controller may preferably be configured to schedule and manage the wash cycles according to an automatable schedule regarding the start, end, duration and / or intensity of the wash cycles, and may also monitor fill levels etc.

[0089] In one refinement, it may be provided that the cleaning channel device comprises a generator for partially converting the kinetic energy of the supplied liquid (cleaning liquid and / or liquid used in the conventional operation of the bath) into electrical energy, preferably for the purpose of providing a self-sufficient power supply for the electronic components of the cleaning channel device. In this way, it is possible to control the cleaning channel device without access to an electrical connection.

[0090] The power plant may in particular consist of a water turbine and an electric generator connected to the water turbine.

[0091] Optionally, an electrical energy storage device, such as a rechargeable battery pack, may be provided to store the electrical energy generated by the power generation device. The electrical energy storage device, in particular a replaceable or rechargeable energy storage device, may be provided as a comprehensive alternative to the power generation device. In this way, the cleaning flow path device can operate autonomously, at least for a while.

[0092] The generator may preferably be located directly upstream, downstream or at the interface of the profile assembly. However, placement in the supply or distribution line to the interface may also be provided. It may also be provided to connect the generator to any liquid supply line of the tank, and, if appropriate, to a conventional fitting of the tank (i.e., for example, a building angle valve). The generator may be equipped with a 3 / 8 inch coupling, in particular for the purpose of connecting to the liquid supply line.

[0093] The invention also relates to a basin, in particular a sink or washbasin, comprising a cleaning channel device according to the above and below description.

[0094] Advantageously, a self-cleaning recirculating cleaning channel basin can be provided. Dirt, food residue, bacteria, etc. that falls into the basin according to the invention generally cannot accumulate on the side walls and can be easily washed away or removed by the cleaning channel device. Therefore, even if dirt does adhere to the basin side walls, it can be easily removed thereafter. In this way, the basin can be self-cleaning or at least support manual cleaning.

[0095] The present invention can significantly improve hygiene conditions when baths are operated, for example in hospitals, nursing homes, medical practices, laboratories, private homes, and even in the food industry. The possibility of infection and contamination of sinks or washbasins, for example, can be significantly reduced by the present invention.

[0096] It may be provided that the cleaning channel arrangement is glued, screwed or in any other way removably or non-removably connected to the bath. As already mentioned above, it is also possible to provide that the cleaning channel arrangement and the bath are integral.

[0097] The cleaning channel arrangement for rinsing the bath may be mechanically and / or electronically actuated.

[0098] The rinse (cleaning) interval or rinse intervals for rinsing the bath with the cleaning channel device can preferably be freely selectable and definable, for example by a timing circuit.

[0099] In order to operate the cleaning channel arrangement, a control device, in particular as described above, may be provided, for example for the purpose of controlling valves, pumps, electromechanical nozzles and / or for evaluating sensors and actuation switches.

[0100] The controller may be in the form of a microprocessor, or alternatively any desired additional device for implementing the controller, such as one or more arrangements of discrete electrical components on a printed circuit board, a stored program controller (SPC), an application specific integrated circuit (ASIC) or another programmable circuit, such as a field programmable gate array (FPGA), a programmable logic array (PLA), and / or an off-the-shelf computer.

[0101] The vessel can be made of metal, in particular metal sheet, ceramic and / or plastic material. The vessel can also be made preferably of a composite material, for example a quartz composite material. Of course, a combination of various materials is also possible. In principle, the vessel can be made of any desired material.

[0102] The cleaning channel device, in particular the profile assembly of the cleaning channel device, can preferably be made from a plastic material. In principle, however, the cleaning channel device or the profile assembly can be made from any desired material, for example, metal. Of course, combinations of various materials can also be provided.

[0103] In an advantageous refinement of the invention, it can be provided that the discharge area of ​​the cleaning channel device is designed so that the liquid discharged from the discharge area rinses at least one side wall of the tank, preferably two side walls of the tank, more preferably three side walls of the tank, and very particularly preferably four side walls of the tank or all side walls of the tank.

[0104] The cleaning channel device is particularly preferably arranged in the bath so that the cleaning channel device can rinse the entire inside of the bath.

[0105] In principle, the tank can be provided with any desired optional components, in particular a liquid outlet (outflow, downpipe and / or siphon) for the liquid, a liquid drain, a deposition surface, etc.

[0106] As a refinement, it may in particular be provided that the tank comprises a fitting supplied by a main supply line (in particular with drinking water or mains water).

[0107] The main supply line is preferably fluidly connected to the liquid supply line and / or the interface of the cleaning channel device and supplies the same liquid to the reservoir via the fitting and via the discharge area of ​​the cleaning channel device.

[0108] Preferably, the supply of liquid via the cleaning channel device together with the liquid supply line is adjustable by the coupling, e.g. to allow simultaneous or synchronous discharge of liquid from the coupling and the cleaning channel device. The fluid connection between the main supply line and the liquid supply line may be arranged downstream of the valve of the coupling in the flow direction, e.g. to adjust the discharge of liquid from the cleaning channel device via the valve of the coupling.

[0109] However, the fluid connection between the main supply line and the liquid supply line is preferably arranged upstream of the valve of the fitting in the flow direction, which makes it easier to retrofit the cleaning channel device into existing tanks or to use the cleaning channel device with conventional fittings, in which case the cleaning channel device may, if appropriate, consist of a separate (electrical and / or mechanical) valve.

[0110] The rinsing action using the cleaning channel device can be optionally activated automatically and / or manually depending on the contamination situation.

[0111] It may also be provided that the fittings and / or cleaning channel arrangements are activated by proximity sensors and / or motion sensors.

[0112] According to one refinement of the invention, it can be provided that the bath or the cleaning channel device comprises at least one radiation source for generating ionizing radiation. A UVC radiation source for generating UVC radiation is preferably provided.

[0113] Ionizing radiation can further enhance the cleaning or sterilizing action of the bath according to the invention or the cleaning channel device according to the invention. The wavelength of the ultraviolet light can be, for example, 100 nm to 400 nm, preferably 200 nm to 300 nm, particularly preferably about or exactly 254 nm.

[0114] In one refinement, the radiation source may be arranged in particular in the liquid outlet of the vessel and / or in the profile assembly. It is also possible to provide several radiation sources.

[0115] The radiation source, in particular the UVC radiation source, is preferably optically shielded, for example located behind a cover for the liquid outlet.

[0116] In one refinement of the invention, it is further possible to provide a drainage device for filtering and draining solids (for example hair and other organic but also inorganic contaminants) from the liquid.

[0117] The discharge device is preferably arranged near the bottom, ie in the lower region of the vessel, or particularly preferably at the liquid outlet of the vessel.

[0118] As a result, solids that accumulate during use of the tank are filtered before entering the drain system, preventing drain blockages, bacterial growth in the drain, and the generation of unpleasant odors.

[0119] In one refinement, it may be provided that the ejector comprises a sheet-like filter element (strip, mat, fabric, film, etc.) through which liquids flow while solids remain on the surface of the sheet-like filter element.

[0120] The surfaces of the filter elements can eventually be cleaned (manually and / or automatically) to remove the solids according to requirements or periodically, for example by transferring the solids to a collection container or by replacing the filter elements.

[0121] In a preferred refinement, the sheet-like filter element is attached to a circulating roller conveyor and can be circulated by driving at least one roller of the roller conveyor, and can discharge the filtered solids on demand and transfer them, for example, to the above-mentioned collection container.

[0122] At this point, it should be noted that this specification also includes the following inventions which are independent of the claims, and the applicant reserves the right to separately claim the mentioned inventions.

[0123] According to a first alternative invention, a bath, in particular a sink or washbasin, is provided with a generator for partially converting the kinetic energy of the liquid fed into the bath into electrical energy. The generator is preferably arranged in the supply line to the bath's fitting. The features of the generator described in connection with the cleaning channel device according to claim 1, and all further features herein, form advantageous refinements of the first alternative invention.

[0124] According to a second alternative invention, there is provided a bath, in particular a sink or washbasin, comprising at least one radiation source for generating ionizing radiation, preferably UVC radiation, the radiation source being preferably arranged in the liquid outlet of the bath. Claim 24 The features of the radiation source described in connection with the vessel described above, and all further features herein, form advantageous refinements of the second alternative invention.

[0125] According to a third aspect of the present invention, there is provided a tank, particularly a sink or washbasin, having at least one discharge device for filtering and discharging solids from a liquid flowing out of the tank, the discharge device being located near the bottom of the tank or at the liquid outlet of the tank. The discharge device preferably comprises a sheet-like filter element through which the liquid can flow away while the solids remain on the surface of the filter element. The sheet-like filter element is preferably mounted on a circulating roller conveyor and can be circulated by driving at least one roller of the roller conveyor to discharge the filtered solids on demand. Claim 24 The features of the discharge device described in connection with the vessel described in 1. above, and all further features herein, form advantageous refinements of the third alternative invention.

[0126] The features described in relation to one of the subject matters of the present invention, in particular the features provided by the cleaning channel device and the bath, can also be advantageously implemented in the other subject matters of the present invention, as well as in the first, second and third independent inventions. Likewise, advantages mentioned in relation to one subject matter of the present invention can also be understood to relate to the other subject matters of the present invention, as well as to the first, second and third independent inventions.

[0127] Furthermore, it should be noted that terms such as "comprising," "having," or "with" do not exclude other features or steps. Furthermore, terms such as "a," "an," or "the" referring to a single number of steps or features do not exclude a plurality of features or steps, and vice versa.

[0128] However, in a pure embodiment of the invention, it may be provided that the features introduced into the invention by the terms "comprising", "having" or "with" constitute an exhaustive list. Thus, within the context of the present invention, one or more lists of features may be considered as self-contained, e.g., for each claim. The invention may, for example, consist solely of the features recited in claim 1.

[0129] It should be noted that designations such as "first" or "second" are primarily used to distinguish the functions of each device or method, and are not necessarily intended to indicate that the functions are mutually necessary or related to each other.

[0130] It should also be emphasized that the values ​​and parameters mentioned herein include deviations or variations in the respective stated value or parameter of not more than ±10%, preferably not more than ±5%, more preferably not more than ±1%, and very particularly preferably not more than ±0.1%, provided that these deviations are not excluded when actually carrying out the invention. Furthermore, the specification of ranges by starting and ending values ​​includes all values ​​and fractions included in the respective stated ranges, in particular the starting and ending values ​​and the respective average values.

[0131] Exemplary embodiments of the invention are explained in more detail below on the basis of the drawings.

[Figure 10] FIG. 1 shows a discharge device for filtering and discharging solids from the liquid at the liquid outlet of the tank. DETAILED DESCRIPTION OF THE INVENTION

[0135] 1 to 4 show a cleaning channel device 1 according to a first exemplary embodiment of the present invention. The geometric dimensions and relationships should be understood as merely exemplary in the drawings to explain the functional principles of the present invention.

[0136] The cleaning channel device 1 includes a profile assembly 2, which in the exemplary embodiment shown in Figures 1 to 4 has a multi-part configuration, but which in principle can also have a single-part configuration. As can be seen particularly well in Figure 3, which should be understood as merely an example, the profile assembly 2 comprises a first profile part 3 and a second profile part 4. This allows for simplified manufacturing of the cleaning channel device 1.

[0137] The profile assembly 2 has at least one interface 5 for supplying a liquid (preferably water or tap water). The interface 5 has a recess 6 in a side wall of the profile assembly 2 that extends along the longitudinal axis L of the cleaning channel device 1. A liquid supply line 7 (see FIG. 5) may be connectable to the interface 5.

[0138] Liquid can be introduced into distribution lines 8 of the profile assembly 2 via interface 5. The distribution lines 8 extend completely through the profile assembly 2 along the longitudinal axis L of the profile assembly 2 to distribute the liquid around the cleaning channel device 1.

[0139] In principle, it is also possible to provide further interfaces 5 for supplying liquid, for example an interface 5 on each side of the profile assembly 2. However, it is preferred to provide only a single interface 5.

[0140] The profile assembly 2 also has a discharge area 9 for discharging liquid. The discharge area 9 also extends completely through the profile assembly 2 along the longitudinal axis L of the profile assembly 2. The discharge area 9 is in the form of a discharge slot extending along the longitudinal axis L of the profile assembly 2. The discharge area 9 map preferably optionally includes an elastic diaphragm 10, such as a rubber lip (shown in dashed lines in FIG. 2), designed to close the discharge area 9 when no liquid is being discharged from it. This can improve sterility of the cleaning channel device 1.

[0141] It is provided that the profile assembly 2 comprises a flow channel 11 extending along a flow channel course K from the distribution line 8 to the discharge area 9 (see Figures 1 and 2). The flow channel 11 also extends through the profile assembly 2 along the longitudinal axis L of the profile assembly 2. In this respect, the flow channel course K is aligned perpendicular to the longitudinal axis L of the profile assembly 2 (see in particular Figure 1).

[0142] The flow channel 11 can make the flow of liquid ejected from the ejection area 9 particularly uniform and laminar, thereby improving the cleaning action of the cleaning channel device 1 according to the invention.

[0143] The distribution line 8 , the flow passage 11 and the discharge area 9 preferably extend over the same length along the longitudinal axis L of the profile assembly 2 .

[0144] The distribution line 8 has a maximum flow path diameter (or a maximum flow path width) D max The distribution channel diameter (or distribution channel width) D is larger than V (see FIG. 2). The distribution line 8 can merge with the flow channel 11 in particular along a cross-sectional narrowing 12.

[0145] Furthermore, the discharge area 9 or the discharge slot is such that the minimum flow path diameter (minimum flow path width) D min Discharge diameter (or discharge width) D AIt may be specified that the discharge diameter or discharge width D A may be, for example, about or exactly 0.1 mm to 2.0 mm, in particular about or exactly 0.8 mm.

[0146] As can be seen particularly well in Figures 1 and 2, the flow channel 11 forms a number of bends 13 along the flow channel course K. In the exemplary embodiment, exactly three bends 13 are provided. Optionally, the flow channel 11 has a smaller cross section along the bends 13, in particular according to a minimum flow channel diameter or minimum flow channel width Dmin. The loop formed by the flow channel 11 can have a particularly positive effect on the liquid flow and can also eliminate backflow and therefore carryover of bacteria into the cleaning flow channel device 1.

[0147] The cleaning channel device 1 may be in the form of an integral part of the tank 14 (see Figures 1 to 4 and 7) or an insert into the tank 14 (see Figure 6). In the exemplary embodiment shown in Figures 1 to 4, the first profile part 3 is formed integrally with the tank 14. The tank 14 and the second profile part 4 therefore together form a profile assembly 2. In the case of a second exemplary embodiment not yet described below, the two-part cleaning channel device 1 can be inserted into an existing tank 14, with the last loop of the channels 11 and the discharge area 9, or discharge slot, being formed between the first profile part 3 and the tank 14.

[0148] In the exemplary embodiment, the profile assembly 2 has an essentially closed annular course along its longitudinal axis L (see in particular FIG. 4). However, in principle, the profile assembly 2 does not have to be completely essentially closed and may, for example, simply cover a single side wall 15 or a portion of a side wall 15 of the tank 14.

[0149] Optionally, it may be provided that the discharge area 9, the flow passages 11 and / or the distribution lines 8 comprise ribs 16 extending between their respective side walls. Purely by way of example, a single rib 16 is shown adjacent the discharge area 9 in Figure 3. The rib 16 may improve the stability of the profile assembly 2 and further optimize the flow path.

[0150] The cleaning flow path apparatus 1 may be provided with at least one supply device 17 for supplying an additive 18 to the liquid. An exemplary supply device 17 is shown schematically in FIG. 5. The additive 18 may be, for example, a cleaning substance, a disinfectant, a descaler, etc. The supply device 17 may include a reservoir 19 for supplying the additive 18. To transport and / or meter the additive, the supply device 17 may include a pump, such as the illustrated electronically actuated pump 20, a mechanically / electronically actuated valve, and / or a Venturi nozzle.

[0151] The cleaning channel device 1 may include a controller 21 configured to control and / or monitor, preferably in response to user input, the dispensing of liquid from the dispensing region 9. The controller 21 is shown in dashed lines in Figure 5 and is illustratively communicatively connected to a pump 20 for the purposes of operating the controller.

[0152] A power generator 22, also shown in dashed lines in Figure 5, may be provided in the liquid supply line 7 in order to preferably self-sufficiently supply power to the cleaning channel device 1, e.g., the control device 21, the pump 20, etc. The optional power generator 22 can in principle be provided in the cleaning channel device 1 or in the tank 14 at any desired location through which the liquid flows.

[0153] 6, already mentioned, shows a two-part cleaning channel device 1 according to a second exemplary embodiment of the invention. The cleaning channel device 1 is in the form of an insert for and can be inserted into a bath 14, which is shown only diagrammatically (preferably made of metal). The discharge area 9 is formed between the profile assembly 2 of the cleaning channel device 1 and each side wall 15 of the bath 14. This is intended to show that, if the cleaning channel device 1 is formed essentially independently of the bath 14, the bath 14 can also function as a functional component of the profile assembly 2.

[0154] 7 shows a basin 14 (for example a sink) into which the cleaning channel device 1 according to the present invention is fully integrated. The basin 14 includes various known components of the basin 14, and in this respect in particular a fitting 23 supplied by a main supply line, not shown in detail. The main supply line is preferably fluidly connected to the liquid supply line 7, or interface 5, of the cleaning channel device 1, and supplies the same liquid, preferably drinking water or mains water, to the basin 14 via the fitting 23 and via the discharge area 9 of the cleaning channel device 1.

[0155] The discharge area 9 of the cleaning channel device 1 is preferably designed so that the liquid discharged from the discharge area 9 rinses all the inner walls or side walls 15 of the tank 14. However, in principle, it may also be provided that the cleaning channel device 1 rinses only a portion of the side walls 15 of the tank 14 or only a portion of an individual side wall 15 of the tank 14.

[0156] 7, a radiation source 24 can be provided to generate ionizing radiation and sterilize the liquid before and / or after it flows through the vessel 14 or components of the vessel 14. In this regard, at least one radiation source, in particular a UVC radiation source for generating UVC radiation, is preferably arranged in the liquid outlet 25 of the vessel 14. The ionizing radiation can be optically shielded, for example, by a protective metal sheet 26.

[0157] It should be noted that in principle it is also possible to distribute several cleaning channel devices 1 within a common bath 14 .

[0158] To illustrate further refinements that can be combined with all exemplary embodiments, FIG. 8 shows a cross-sectional side view of the first profile part 3 of a further cleaning channel device 1, which has a distribution element 27 arranged in the region of the interface 5 for supplying liquid. FIG. 9 shows a plan view of the distribution element 27 of the cleaning channel device 1. The distribution element 27 is arranged in the distribution line 8 in the region of the interface 5 and guides the liquid supplied via the interface 5 through the distribution line 8 in at least two different directions (see arrows in FIG. 9 ). To this end, the distribution element 27 is arranged on the inner wall of the distribution line 8, facing away from the interface 5 in the liquid supply direction, and aligned towards the interface 5 by means of a tapered edge. In the exemplary embodiment, the distribution element 27 has a wedge shape with a concavely curved profile on the side (see FIG. 9 ).

[0159] Finally, a further advantageous configuration of the present invention is shown in FIG. 10 , which includes a discharge device 28 for filtering and discharging solids from the liquid. The discharge device 28 is located at the liquid outlet 25 of the tank 14, thus filtering solids that accumulate during use of the tank 14 before they enter the drainage system. This prevents clogging of the drainage system, the development of bacteria, and unpleasant odors. The discharge device 28 includes a sheet-like filter element 29 through which the liquid can flow away, while the solids remain on the surface of the filter element. The surface of the filter element 29 can eventually be cleaned (manually and / or automatically) to remove the solids as needed or periodically, for example, by transferring the solids to a collection container 30. In an exemplary embodiment, for this purpose, the filter element 29 is attached to a circulating roller conveyor 31, which can be circulated by driving at least one roller of the roller conveyor 31. As a result, the filtered solids can be transferred to the collection container 30. [Explanation of symbols]
