Definitions

• the invention relates to a cleaning device for cleaning individual cutlery parts, in particular knives, with a liquid-tight container which has an opening through which a plug part can be at least partially inserted into the interior of the container.
• the publication DE 37 39 458 shows a bed cleaning device, with which people can remove knives from food residues during a meal, for example when using different spreads. It consists of a closed, preferably heatable, container filled with rinsing liquid and having an opening at the top.
• the cutlery part can be at least partially immersed in the rinsing liquid through the opening, ie up to the handle, and cleaned in this way. This process is facilitated by wiping lips at the opening.
• this device has the same disadvantages as an ordinary sink.
• a further possibility for cleaning cutlery items is provided by commercially available dishwashers, in which cleaning is carried out by liquid jets.
• these devices are not suitable for frequently used objects.
• the invention has set itself the task of developing a device that allows the quick, thorough and hygienically flawless cleaning of individual items of cutlery with little consumption of cleaning fluid.
• the container has nozzles on the inside provided with a feed line, through which a cleaning liquid can be injected, the nozzles are aligned in such a way that the cleaning liquid meets an inserted piece of cutlery, the container has a drain in its lower region, the feed line of the nozzles is provided with a valve and / or a pump and a control device is provided with which the valve or valves or the pump can be switched.
• the proposed cleaning device comprises an almost closed, liquid-tight container which has a drain in its lower region, preferably at its lowest point, the container bottom advantageously being inclined towards the opening. Because of the always open drain, the container is therefore always empty, in contrast to devices known from the prior art, ie there is no liquid in the container. In its interior it is provided with nozzles through which a cleaning fluid supplied via lines can be injected. In the case of cutlery items, water will be particularly suitable for this purpose; for cleaning special tools, for example paintbrushes or spatulas, it is also conceivable to use organic solvents.
• the container is preferably provided with an opening on its upper side or on a side wall, the diameter of which is sufficient to at least partially insert cutlery items, especially the area to be cleaned up to the handle attachment.
• the nozzles in the container are aligned in such a way that the liquid hits the inserted plug-in part and thus cleans it.
• the nozzles thus preferably point to the axis of the container running through the opening.
• the line pressure contributes to the cleaning process.
• individual or all liquid jets can strike the part to be cleaned at an acute angle to the drain opening; It is also conceivable to align individual nozzles on the container inner wall in order to ensure self-cleaning.
• the feed lines of the nozzles are provided with a valve, for the actuation of which there is a control device.
• a pump that can be operated by the control device is appropriate instead of or in addition to valves.
• the valves are opened or the pump is only operated when the object to be cleaned is inside the container. It is expedient, for example, to inject cleaning liquid only while a piece of cutlery is being pushed in and / or pulled out of the container or only when the part has been fully inserted up to the handle. In this way, low consumption can be achieved despite the liquid being used once.
• valves in the central feed line of all nozzles While in simple cases a valve in the central feed line of all nozzles is sufficient, the feed lines of individual or small groups of nozzles can also be equipped with valves for realizing special cleaning processes.
• the advantage is the possibility Ability to open the container, for example by means of a detachable lid, so that its interior is easily accessible for the purpose of removing deposits, for maintenance and for repairs.
• the cleaning device according to the invention allows thorough and hygienically flawless cleaning of individual cutlery items.
• it is also suitable for cleaning any other work tools or workpieces, provided that they can be handled with an area of the handle and are of elongated shape so that they can be inserted through the opening, e.g. Brushes by painters. Since the cleaning liquid always flows out directly through the drain, the device is largely self-cleaning and therefore requires little maintenance.
• Its installation in or on a table or a workbench is particularly advantageous, so that it is arranged directly in the work area and is always within easy reach while handling the cutlery. Regular and frequent cleaning of equipment is thus possible with almost no loss of time.
• the device can be retrofitted to existing workstations as well as integrated into tables or consoles when newly set up.
• the control device is operated with a switch, or in the simplest case is formed by the switch. Both hand and foot switches which the user actuates while the cutlery part is in the Container is inserted. Pushbuttons as switches ensure that no accidental operation takes place after the cleaning process has ended.
• the control device is actuated by a trigger unit which is arranged in the container or at its opening. It automatically triggers the cleaning process when an object is introduced or in its inserted state.
• a trigger unit which is arranged in the container or at its opening. It automatically triggers the cleaning process when an object is introduced or in its inserted state.
• a large number of different release units can be used, for example using mechanical contacts, which are activated by pressing a handle against the edge of the opening or in its immediate vicinity or by means of a rotatable sleeve in the opening Insertion of an object can be triggered.
• Alternatives are electrical contacts or optical devices, such as a light barrier in or immediately behind the opening. If the length of the plug-in parts is always the same, the release unit can be arranged in the container opposite the opening, so that the release takes place after it has been fully inserted.
• the device is used for cleaning plug-in parts of different lengths.
• nozzles evenly distributed over the container and comparatively short parts, a larger number of jets do not strike the cutlery part, so that the liquid is lost unused.
• all surface areas of the cutlery part are guided through the nozzle plane and cleaned uniformly in the process.
• a container in the interior of which one or more scrapers are arranged, along which the cutlery part can be moved.
• Lips made of rubber or an elastic plastic are particularly suitable as wipers.
• the wipers can also be used to remove residues of the cleaning liquid, so that drying of the cleaned cutlery parts is unnecessary.
• the arrangement of a scraper in the region of the opening is particularly advantageous for drying purposes. It can also serve as a seal in order to prevent the cleaning liquid from splashing out during the cleaning process.
• An alternative possibility of sealing the opening consists in parallel rollers, between which the cutlery part is inserted and at the same time serve to actuate the trigger unit.
• wipers and / or seals are preferred which consist of several parts which are movable relative to one another perpendicular to the direction of insertion of the cutlery part.
• the parts can be moved, for example, by a spring mechanism, electromagnets or a motor, which are preferably actuated by the control device. The movement is advantageously carried out in such a way that the parts of the wiper or seal
• Pushing in the cutlery part are spaced apart and lie on its surface during the cleaning or after its completion for mechanical cleaning, drying or sealing.
• a detachable fastening of wipers and seals of the opening is expedient in order to be able to clean them carefully, e.g. in a dishwasher.
• the cleaning device has a storage container for the cleaning liquid and a pump for the cleaning liquid Funding on. This opens up the possibility of operating the device independently of a connection to a supply line, for example at a sales stand or cart. Furthermore, the addition of additives, such as a dishwashing or disinfectant, is made easier with a metering device in a storage container.
• the storage container can be heated. It is also conceivable to introduce a continuous-flow heater into the feed lines of the nozzles.
• the advantage, in particular with water as the cleaning liquid, is that the ability to remove fat significantly improves with increasing temperature.
• the hot cleaning liquid has a germicidal effect at a sufficient temperature.
• the cleaning takes a certain amount of time, the draining liquid becoming increasingly clean towards the end of the process. If adequate hygiene is ensured, for example by heating or a disinfectant, and a circulation pump for conveyance is available, it is conceivable to at least partially return the cleaning liquid to the storage container in order to reduce consumption.
• the liquid already used can be used in particular to remove the coarsest soiling at the start of cleaning, whereas fresh cleaning medium is preferred for rinsing towards the end of the process. Should only be one If part of the draining liquid is to be reused, a T-piece, possibly with a change-over valve, must be inserted into the drain, which allows the heavily contaminated liquid to drain before it is returned.
• the control can be carried out using the control device and a timer or a sensor for determining the degree of contamination.
• the interior of the container is preferably easily accessible by releasably attaching the lid or one or more walls, e.g. with bayonet locks. Complete disassembly of the container is also conceivable. It is advisable in this case to provide an inner container in which the cutlery parts are cleaned and which in turn can be removed from an outer container for easy cleaning. Furthermore, a sieve can be provided in front of the drain, which collects coarse dirt and thus prevents clogging.

• the cleaning device comprises a container (1) which can be admitted, for example, into the plate of a table and has an opening on its top.
• a piece of cutlery (10), for example a knife, can be inserted through the opening, with the exception of its handle, along the axis of the container into the interior of the container.
• the liquid-tight container (1) has a drain (9) on the bottom, so that a cleaning liquid (8), preferably water, injected into it through nozzles (6) can drain freely and its interior is always almost empty. In this way it is avoided that the cleaning liquid (8) is in the container (1) and offers hygienically questionable microorganisms good opportunities for life.
• the cleaning liquid (8) is supplied via a supply line (5).
• axially movable or pivotable switching levers (7) are arranged near the opening, with which the valves of the nozzles (6) can be actuated.
• the switch lever (7) opens the valve.
• the cleaning liquid (8) is thus only injected into the container (1) when the cutlery part (10) to be cleaned is in a suitable position.
• the Nozzles (6) are arranged in a plane which is adjacent to the opening of the container (1). When pulling out, the entire inserted part of the knife is guided through the plane of the nozzles (6) and cleaned of the cleaning liquid (8), a sufficient spray duration being achievable by means of the trigger unit or timer.
• the opening is also provided with a scraper (3).
• the stripper (3) closes the opening, so that the cleaning liquid (8) is not sprayed out.
• its cover (2) is detachably fastened with a closure (4), for example a bayonet closure.
• Figure 2 shows the top view of the lid (2) of the container (1), the arrangement of the scraper (3) being clearly visible. It can be detached from the cover (2) for cleaning or replacement.
