Definitions
- the invention relates to a cleaning cartridge for cleaning a soiled interior of a stove or steamer.
- the invention also relates to a device with such a cartridge and the use of such a cleaner cartridge in a method for cleaning such devices.
- DE 10 2006 025 508 A1 refers to a cleaning system for cleaning a baking or combi steamer appliance.
- filled or filled dispenser containers are positioned with liquid and / or liquid-form-treated cleaning agents.
- the dispenser containers are each connected via a pipe and controlled by a control device regulating units to a compressed air and / or pressurized water supply line.
- the dispenser containers are connected in each case via an exit tube with the baking / cooking space.
- a arranged under the baking / cooking space drain tank is connected via a pipe and a circulating pump with at least one housed in the oven spray head.
- Disadvantage of this solution is a cumbersome handling and the restriction to liquid cleaner.
- a solids cleaner must be transferred outside the cooking chamber and outside the cartridge manually by dissolution into a liquid product. Only then can a dispensing container be inserted into the cooking chamber and the liquid product released from the dispensing container and distributed by means of further, fixedly mounted in a cooking appliance or oven devices to be mounted, such as a fan or a nozzle.
- US 2010/0072188 A1 has a cooking appliance to the object.
- An enamel coating containing a phosphate-based additive is applied to an interior surface that defines a cooking chamber. The inner surface of the cooking chamber is cleaned in such a way that high-temperature cleaning water is used. This allows effective cleaning of the walls of the cooking chamber.
- WO 2008/032138 A1 has a washing device to the object.
- the washing device is particularly suitable for cleaning chambers of various devices for industrial and household applications.
- the washing device essentially comprises a rotary body, which is constructed from disc-shaped elements which are received on a bearing bush. About the bushing, the washing fluid is supplied.
- the disk-shaped parts are shaped such that when they are exposed to the washing fluid, a number of rotating washing jets are directed at different impact surfaces and also impact the surfaces of objects.
- the complex structure of the washing device described herein and their complex fluid management make this washing device very sensitive to clogging by dirt particles or poorly soluble detergent components, which can lead to a concomitant blockage of rotation.
- EP 1 582 265 A2 has a dispenser apparatus to the object.
- a collecting body collects fluid to be dispensed, which is distributed via a suitable rotor.
- This static rotor is connected to the collecting body by a rotary coupling, wherein the collecting body is designed such that it receives on its inside an essential part of the body of the rotor.
- the rotary coupling parts comprise fastening means with a sealing disc, which are located between the rotor and the collecting body.
- US 2009/0178664 A1 describes a cleaning cartridge with a rotating spray arm for cleaning an interior of a roasting oven.
- the object of the present invention is to provide a simplified cleaning system for appliances, in particular for the heat treatment of food, which is simple in design as well as in handling. So should be ensured by as few additional built-in service friendliness and failure-prone parts should be reduced or be exchangeable as a disposable component. Furthermore, a high degree of hygiene is to be achieved without loose dirt particles must be removed manually.
- the cleaner cartridge may have a filling volume of 25 ml to 500 ml, preferably from 50 ml to 450 ml and more preferably from 75 ml to 300 ml.
- the volume of the housing may be selected such that treatment agent can be accommodated for exactly one cleaning process. The need for treatment depends on the length of the cleaning process and the volume to be cleaned.
- the housing of the cleaner cartridge can be designed as a plastic housing.
- Such housings may include, for example, a plastic such as polyvinyl chloride (PVC), polyethylene (PE), especially lightly branched polyethylene (High Density Polyethylene, HDPE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyamide, polystyrene, polyurethane, polyethylene terephthalate, or mixtures thereof include.
- a plastic such as polyvinyl chloride (PVC), polyethylene (PE), especially lightly branched polyethylene (High Density Polyethylene, HDPE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyamide, polystyrene, polyurethane, polyethylene terephthalate, or mixtures thereof include.
- the housing is made of a plastic, which is not attacked by the stored in the housing treatment agent.
- the housing is made of a plastic which is resistant to the temperatures prevailing during the cleaning cycle. Typical temperatures are 30 ° C to 100 ° C, preferably 50 ° C to 90 °
- the housing of the cleaner cartridge can be designed as a metal housing.
- the treatment agent may contain, for example, a cleaning agent and / or a descaling agent.
- a cleaning agent are particularly suitable alkaline cleaning agents which have a pH of> 7, preferably between 9 and 13 in aqueous solution.
- alkaline detergents are, for example, alkali metal hydroxides, alkali metal carbonates, phosphates, silicates, peroxides, percarbonates, methylglycinediacetic acid (MGDA), phosphates, polycarboxylates, enzymes or mixtures thereof.
- surface-active substances such as surfactants, emulsifiers or inhibitors can be used.
- Common descaling agents may be, for example, citric acid, methanesulfonic acid (MSA), sulfamic acid, malic acid, maleic acid, tartaric acid, acetic acid, or mixtures thereof.
- the treatment agent can be taken up as granules, as a powder, as a gel, as a block, as a tablet or in liquid form in the housing.
- the treatment agent is received as a tablet, granules, powder, block or gel in the housing so as not to be able to escape unintentionally, for example during transport through the spray openings.
- the openings may be closed, for example with a peelable film, a tear-able film of a few microns, or a water-dissolvable film.
- the openings may be closed with a wax that melts at a certain temperature.
- the treatment agent can be released temperature-controlled.
- the openings may be closed by a water-soluble saccharide.
- the receptacle can be designed as a fixed or rotatable receptacle.
- the receptacle is designed for coupling the cleaner cartridge to a cleaning system of the device.
- the receptacle may have a closure, such as a screw cap or a bayonet closure.
- a connection element of the cleaning system can be made rotatable.
- the receptacle of the cleaner cartridge can be designed to be rotatable and the connection element of the cleaning system to be fixed.
- the housing is cylindrical with a peripheral surface, a cartridge head, and a bottom surface.
- the base of the cylinder can take any shape, such as round or square.
- an angular, in particular a rectangular shape or a housing in the form of a spray arm has the advantage that given a volume compared to a round shape, a greater distance to the axis of rotation and the greatest proximity to the side walls to be cleaned can be achieved. As a result, a stable rotation and a good cleaning result can be achieved.
- the receptacle can be arranged on the cartridge head of the housing.
- the housing may be closed or at least one spray opening may be disposed on the underside of the housing.
- the spray openings configured as rotation openings can be deformed inward in the direction of the tangential or inclined as a recess, so that the spray openings spray treatment agent mixture in the tangential direction.
- at least two rotational openings are arranged on the peripheral surface of the housing such that two tangentially directed jets with opposite spraying direction are produced during spraying.
- the rotation openings are designed in such a way that, in the case of a rotatably mounted cleaner cartridge, the cleaner cartridge is set into a rotational movement by the spraying of treatment agent mixture.
- a rotational opening may be sufficient if the torque generated by the removal of the outlet opening to the pivot point initiates a rotational movement of the cleaner cartridge.
- the spray openings are arranged at a regular distance on the peripheral surface of the housing; Particularly preferably, two spray openings on the peripheral surface of the housing are arranged opposite one another, which set the housing of the cleaner cartridge in rotation of the spray jets of the treating agent mixture in rotation.
- rotational bodies can be arranged on the peripheral surface of the housing, which support a rotational movement of the cleaner cartridge.
- the rotation bodies are arranged opposite one another and comprise spray openings which serve as rotation openings and generate the rotation of the housing.
- the spray openings can be arranged on opposite sides of the two bodies of revolution, in order to generate a spray jet in the opposite direction and so set a rotational movement of the housing in motion.
- the spray holes can be arranged on the rotating bodies and the volume of the cleaner cartridge is not reduced by a chamfer of the peripheral surface.
- the distance from the fulcrum is increased and thus higher torque is achieved with respect to spray orifices integrated into the peripheral surface of the housing.
- additional spray openings may be arranged on the peripheral surface of the housing, the underside of the housing and / or on the rotational bodies, which have a smaller diameter than the spray openings, which cause the rotation of the housing.
- the additional spray openings are designed as holes in the peripheral surface of the housing. The additional spray openings support the mechanical removal of dirt particles in order to reach problematic areas of the room to be cleaned.
- a retaining device for example a collecting sieve, is arranged inside the housing.
- the built-in restraint allows the cleaner cartridge to form a strainer for cleaning systems with a cleaning solution return loop, which is removed along with the cleaner cartridge.
- a sieving device installed in the device or parts thereof. For example, it may be sufficient to provide a coarse sieve in the device which retains coarse food particles, such as bones, which could block a pump.
- a pump may be clocked.
- the retention device in the cleaner cartridge released by a return of dirt particles and it is possible to make the sieve area smaller in relation to the amount of dirt particles.
- a pump such as a recirculation pump

The cleaning cartridge is designed as a disposable cartridge, which is already filled with treatment agent and is used before each cleaning process. Depending on the configuration, the cleaner cartridge can thus store enough treatment agent for a cleaning process.
Beispielsweise kann die Reinigerkartusche ein Füllvolumen von 25 ml bis 500 ml, bevorzugt von 50 ml bis 450 ml und besonders bevorzugt von 75 ml bis 300 ml aufweisen. So kann das Volumen des Gehäuses derart gewählt sein, dass Behandlungsmittel für genau einen Reinigungsvorgang aufgenommen werden kann. Der Bedarf an Behandlungsmittel hängt dabei von der Länge des Reinigungsvorganges und dem zu reinigenden Volumen ab.
Weiterhin kann das Gehäuse der Reinigerkartusche als Kunststoffgehäuse ausgeführt sein. Derartige Gehäuse können beispielsweise einen Kunststoff, wie Polyvinylchlorid (PVC), Polyethylen (PE), insbesondre schwach verzweigtes Polyethylen (High Density PolyEthylen, HDPE), Polypropylen (PP), Polytetrafluorethylen (PTFE), Polyamid, Polystyrol, Polyurethan, Polyethylenterephthalat oder Mischungen hieraus umfassen. Bevorzugt ist das Gehäuse aus einem Kunststoff gefertigt, der durch die im Gehäuse bevorrateten Behandlungsmittel nicht angegriffen wird. Weiterhin ist das Gehäuse aus einem Kunststoff gefertigt, der bei den während des Reinigungsgangs herrschenden Temperaturen beständig ist. Typische Temperaturen sind 30°C bis 100°C, bevorzugt 50°C bis 90°C und besonders bevorzugt 60°C bis 85°C. Alternativ kann das Gehäuse der Reinigerkartusche als Metallgehäuse ausgestaltet sein.
Das Behandlungsmittel kann beispielsweise ein Reinigungsmittel und/oder ein Entkalkungsmittel enthalten. Als Reinigungsmittel eignen sich insbesondere alkalische Reinigungsmittel, die in wässriger Lösung einen pH-Wert von > 7, bevorzugt zwischen 9 und 13 aufweisen. Häufig verwendete Komponenten alkalischer Reiniger sind zum Beispiel Alkalihydroxide, Alkalicarbonate, Phosphate, Silikate, Peroxide, Percarbonate, Methylglycindiessigsäure (MGDA), Phosphate, Polycarboxylate, Enzyme oder Mischungen hieraus. Zusätzlich können oberflächenaktive Substanzen, wie Tenside, Emulgatoren oder Inhibitoren eingesetzt werden. Gängige Entkalkungsmittel können zum Beispiel Zitronensäure, Methansulfonsäure (MSA), Amidosulfonsäure, Apfelsäure, Maleinsäure, Weinsäure, Essigsäure oder Mischungen hieraus sein.For example, the cleaner cartridge may have a filling volume of 25 ml to 500 ml, preferably from 50 ml to 450 ml and more preferably from 75 ml to 300 ml. Thus, the volume of the housing may be selected such that treatment agent can be accommodated for exactly one cleaning process. The need for treatment depends on the length of the cleaning process and the volume to be cleaned.
Furthermore, the housing of the cleaner cartridge can be designed as a plastic housing. Such housings may include, for example, a plastic such as polyvinyl chloride (PVC), polyethylene (PE), especially lightly branched polyethylene (High Density Polyethylene, HDPE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyamide, polystyrene, polyurethane, polyethylene terephthalate, or mixtures thereof include. Preferably, the housing is made of a plastic, which is not attacked by the stored in the housing treatment agent. Furthermore, the housing is made of a plastic which is resistant to the temperatures prevailing during the cleaning cycle. Typical temperatures are 30 ° C to 100 ° C, preferably 50 ° C to 90 ° C, and most preferably 60 ° C to 85 ° C. Alternatively, the housing of the cleaner cartridge can be designed as a metal housing.
The treatment agent may contain, for example, a cleaning agent and / or a descaling agent. As a cleaning agent are particularly suitable alkaline cleaning agents which have a pH of> 7, preferably between 9 and 13 in aqueous solution. Frequently used components of alkaline detergents are, for example, alkali metal hydroxides, alkali metal carbonates, phosphates, silicates, peroxides, percarbonates, methylglycinediacetic acid (MGDA), phosphates, polycarboxylates, enzymes or mixtures thereof. In addition, surface-active substances, such as surfactants, emulsifiers or inhibitors can be used. Common descaling agents may be, for example, citric acid, methanesulfonic acid (MSA), sulfamic acid, malic acid, maleic acid, tartaric acid, acetic acid, or mixtures thereof.
Weiterhin kann das Behandlungsmittel als Granulat, als Pulver, als Gel, als Block, als Tablette oder in flüssiger Form in dem Gehäuse aufgenommen sein. Bevorzugt ist das Behandlungsmittel als Tablette, Granulat, Pulver, Block oder Gel in dem Gehäuse aufgenommen, um nicht unbeabsichtigt, zum Beispiel während des Transports durch die Sprühöffnungen entweichen zu können. Weiterhin können die Öffnungen verschlossen sein, beispielsweise mit einer abziehbaren Folie, einer reißfähigen Folie von wenigen µm, oder einer durch Wasser auflösbare Folie. Weiterhin können die Öffnungen mit einem Wachs verschlossen sein, das bei einer bestimmten Temperatur schmilzt. So kann das Behandlungsmittel temperaturgesteuert freigesetzt werden. Alternativ können die Öffnungen durch ein wasserlösliches Saccharid verschlossen sein.Furthermore, the treatment agent can be taken up as granules, as a powder, as a gel, as a block, as a tablet or in liquid form in the housing. Preferably, the treatment agent is received as a tablet, granules, powder, block or gel in the housing so as not to be able to escape unintentionally, for example during transport through the spray openings. Furthermore, the openings may be closed, for example with a peelable film, a tear-able film of a few microns, or a water-dissolvable film. Furthermore, the openings may be closed with a wax that melts at a certain temperature. Thus, the treatment agent can be released temperature-controlled. Alternatively, the openings may be closed by a water-soluble saccharide.
In einer weiteren Ausführungsform kann die Aufnahme als feststehende oder als drehbare Aufnahme ausgestaltet sein. Bevorzugt ist die Aufnahme zum Koppeln der Reinigerkartusche an ein Reinigungssystem des Geräts ausgestaltet. So kann die Aufnahme einen Verschluss, wie einen Schraubverschluss oder einen Bajonettverschluss, aufweisen. Beispielsweise kann bei einer feststehenden Aufnahme der Reinigerkartusche ein Anschlusselement des Reinigungssystems drehbar ausgestaltet sein. Umgekehrt kann auch die Aufnahme der Reinigerkartusche drehbar ausgebildet sein und das Anschlusselement des Reinigungssystems feststehend sein.In a further embodiment, the receptacle can be designed as a fixed or rotatable receptacle. Preferably, the receptacle is designed for coupling the cleaner cartridge to a cleaning system of the device. Thus, the receptacle may have a closure, such as a screw cap or a bayonet closure. For example, in the case of a fixed receptacle of the cleaner cartridge, a connection element of the cleaning system can be made rotatable. Conversely, the receptacle of the cleaner cartridge can be designed to be rotatable and the connection element of the cleaning system to be fixed.
In einer weiteren Ausführungsform ist das Gehäuse zylindrisch mit einer Umfangsfläche, einem Kartuschenkopf und einer Unterseite ausgeführt. Die Grundfläche des Zylinders kann dabei jede beliebige Form annehmen, etwa rund oder eckig. Dabei hat eine eckige, insbesondere eine rechteckige Form oder ein Gehäuse in Form eines Sprüharmes den Vorteil, dass bei gegebenem Volumen gegenüber einer runden Form ein größerer Abstand zur Drehachse sowie die größte Nähe zu den zu reinigenden Seitenwänden erreicht werden. Hierdurch kann eine stabile Rotation sowie ein gutes Reinigungsergebnis erreicht werden.In another embodiment, the housing is cylindrical with a peripheral surface, a cartridge head, and a bottom surface. The base of the cylinder can take any shape, such as round or square. In this case, an angular, in particular a rectangular shape or a housing in the form of a spray arm has the advantage that given a volume compared to a round shape, a greater distance to the axis of rotation and the greatest proximity to the side walls to be cleaned can be achieved. As a result, a stable rotation and a good cleaning result can be achieved.
Die Aufnahme kann an dem Kartuschenkopf des Gehäuses angeordnet sein. An einer gegenüberliegenden Unterseite des Gehäuses kann das Gehäuse geschlossen sein oder wenigstens eine Sprühöffnung kann an der Unterseite des Gehäuses angeordnet sein. Durch die gegenüberliegende Anordnung der Aufnahme und der Sprühöffnungen wird erreicht, dass im Betrieb beispielsweise Wasser zum Lösen des Behandlungsmittels über die Aufnahme in das Gehäuse eingebracht wird und sich dadurch der Druck innerhalb der Kartusche so erhöht, dass das Behandlungsmittelgemisch durch die Sprühöffnungen versprüht wird.The receptacle can be arranged on the cartridge head of the housing. At an opposite bottom of the housing, the housing may be closed or at least one spray opening may be disposed on the underside of the housing. By the opposite arrangement of the receptacle and the spray openings is achieved that in operation, for example, water is introduced to dissolve the treatment agent on the recording in the housing and thereby increases the pressure within the cartridge so that the treatment mixture is sprayed through the spray openings.
Zum Erzeugen einer Rotationsbewegung können die als Rotationsöffnungen ausgestalteten Sprühöffnungen in Richtung der Tangentialen nach innen verformt oder als Einbuchtung geneigt ausgeführt sein, so dass die Sprühöffnungen Behandlungsmittelgemisch in tangentiale Richtung versprühen. In einer weiteren Ausführungsform sind zumindest zwei Rotationsöffnungen an der Umfangsfläche des Gehäuses derart angeordnet, dass beim Versprühen zwei tangential gerichtete Strahlen mit entgegengesetzter Sprührichtung erzeugt werden. Die Rotationsöffnungen sind derart ausgestaltet, dass bei einer drehbar gelagerten Reinigerkartusche durch das Versprühen von Behandlungsmittelgemisch die Reinigerkartusche in eine Rotationsbewegung versetzt wird. Alternativ kann eine Rotationsöffnung ausreichen, wenn das durch die Entfernung der Austrittsöffnung zum Drehpunkt erzeugte Drehmoment eine Rotationsbewegung der Reinigerkartusche initiiert. Dabei ist es vorteilhaft, beispielsweise eine, zwei oder drei Öffnungen vorzusehen, die im Vergleich zu beispielsweise mehr als drei Öffnungen größer dimensioniert sein können, um einen entsprechenden Volumenstrom zu versprühen. Durch den größeren Durchmesser werden diese nicht so leicht von Schmutzpartikeln verstopft.To generate a rotational movement, the spray openings configured as rotation openings can be deformed inward in the direction of the tangential or inclined as a recess, so that the spray openings spray treatment agent mixture in the tangential direction. In a further embodiment, at least two rotational openings are arranged on the peripheral surface of the housing such that two tangentially directed jets with opposite spraying direction are produced during spraying. The rotation openings are designed in such a way that, in the case of a rotatably mounted cleaner cartridge, the cleaner cartridge is set into a rotational movement by the spraying of treatment agent mixture. Alternatively, a rotational opening may be sufficient if the torque generated by the removal of the outlet opening to the pivot point initiates a rotational movement of the cleaner cartridge. It is advantageous, for example, to provide one, two or three openings which, in comparison to, for example, more than three openings, can be dimensioned larger in order to spray a corresponding volume flow. Due to the larger diameter they are not so easily clogged by dirt particles.
In einer bevorzugten Ausführungsform sind die Sprühöffnungen in einem regelmäßigen Abstand an der Umfangsfläche des Gehäuses angeordnet; besonders bevorzugt sind zwei Sprühöffnungen an der Umfangsfläche des Gehäuses einander gegenüberliegend angeordnet, die das Gehäuse der Reinigerkartusche bei Austreten der Sprühstrahlen des Behandlungsmittelgemisches in Rotation versetzen.In a preferred embodiment, the spray openings are arranged at a regular distance on the peripheral surface of the housing; Particularly preferably, two spray openings on the peripheral surface of the housing are arranged opposite one another, which set the housing of the cleaner cartridge in rotation of the spray jets of the treating agent mixture in rotation.
In einer weiteren Ausführungsform können Rotationskörper an der Umfangsfläche des Gehäuses angeordnet sein, die eine Rotationsbewegung der Reinigerkartusche unterstützen. Insbesondere sind die Rotationkörper einander gegenüberliegend angeordnet und umfassen Sprühöffnungen, die als Rotationsöffnungen dienen und die Rotation des Gehäuses erzeugen. Dabei können die Sprühöffnungen auf jeweils entgegengesetzten Seiten an den beiden Rotationskörpern angeordnet sein, um einen Sprühstrahl in entgegengesetzte Richtung zu erzeugen und so eine Rotationsbewegung des Gehäuses in Gang zu setzen. Durch die Rotationskörper können die Sprühöffnungen an den Rotationskörpern angeordnet sein und das Volumen der Reinigerkartusche wird nicht durch eine Abschrägung der Umfangsfläche reduziert. Zusätzlich wird die Entfernung vom Drehpunkt vergrößert und damit gegenüber Sprühöffnungen, die in die Umfangsfläche des Gehäuses integriert sind, ein höheres Drehmoment erreicht.In another embodiment, rotational bodies can be arranged on the peripheral surface of the housing, which support a rotational movement of the cleaner cartridge. In particular, the rotation bodies are arranged opposite one another and comprise spray openings which serve as rotation openings and generate the rotation of the housing. In this case, the spray openings can be arranged on opposite sides of the two bodies of revolution, in order to generate a spray jet in the opposite direction and so set a rotational movement of the housing in motion. By the rotary body, the spray holes can be arranged on the rotating bodies and the volume of the cleaner cartridge is not reduced by a chamfer of the peripheral surface. In addition, the distance from the fulcrum is increased and thus higher torque is achieved with respect to spray orifices integrated into the peripheral surface of the housing.
In einer weiteren Ausführungsform können zusätzliche Sprühöffnungen an der Umfangsfläche des Gehäuses, der Unterseite des Gehäuses und/oder an den Rotationskörpern angeordnet sein, die einen geringeren Durchmesser aufweisen als die Sprühöffnungen, die die Rotation des Gehäuses bewirken. Vorzugsweise sind die zusätzlichen Sprühöffnungen als Löcher in der Umfangsfläche des Gehäuses ausgestaltet. Durch die zusätzlichen Sprühöffnungen wird die mechanische Abtragung von Schmutzpartikeln unterstützt, um problematische Bereiche des zu reinigenden Raumes zu erreichen.In a further embodiment, additional spray openings may be arranged on the peripheral surface of the housing, the underside of the housing and / or on the rotational bodies, which have a smaller diameter than the spray openings, which cause the rotation of the housing. Preferably, the additional spray openings are designed as holes in the peripheral surface of the housing. The additional spray openings support the mechanical removal of dirt particles in order to reach problematic areas of the room to be cleaned.
In einer weiteren Ausführungsform ist innerhalb des Gehäuses eine Rückhaltevorrichtung, beispielsweise ein Auffangsieb, angeordnet. Durch die integrierte Rückhaltevorrichtung kann die Reinigerkartusche bei Reinigungssystemen mit einem Rückführkreis für die Reinigungslösung ein Schmutzfänger bilden, der zusammen mit der Reinigerkartusche entnommen wird. Damit sind keine zusätzlichen Maßnahmen notwendig, um die Schmutzpartikel nach dem Reinigungsvorgang aus dem zu reinigenden Innenraum des Gerätes zu entfernen. Zusätzlich kann auf eine im Gerät eingebaute Siebvorrichtung oder Teile derselben verzichtet werden. So kann es beispielsweise ausreichen, ein Grobsieb im Gerät vorzusehen, das grobe Speisereste, wie Knochen, die etwa eine Pumpe blockieren könnten, zurückhält.In a further embodiment, a retaining device, for example a collecting sieve, is arranged inside the housing. The built-in restraint allows the cleaner cartridge to form a strainer for cleaning systems with a cleaning solution return loop, which is removed along with the cleaner cartridge. Thus, no additional measures are necessary to remove the dirt particles after the cleaning process from the interior to be cleaned of the device. In addition, it is possible to dispense with a sieving device installed in the device or parts thereof. For example, it may be sufficient to provide a coarse sieve in the device which retains coarse food particles, such as bones, which could block a pump.
Bevorzugt kann eine Pumpe getaktet sein. So kann die Rückhaltevorrichtung in der Reinigerkartusche durch einen Rückstrom von Schmutzpartikeln wieder freigegeben werden und es ist möglich, die Siebfläche in Relation zur Menge an Schmutzpartikeln kleiner zu dimensionieren. Wird beispielsweise während des Reinigungsvorgangs eine Pumpe wie eine Umwälzpumpe getaktet, zum Beispiel alle 20 Sekunden, betrieben, so dass in Pausen etwa 5 Sekunden nicht gepumpt wird, läuft der Schmutz aus der innerhalb der Reinigerkartusche befindlichen Rückhaltevorrichtung in das Leitungssystem des Reinigungssystems oder auf den Boden des Innenraums des Gerätes zurück, sofern keine Rückflussverhinderungsvorrichtung vorhanden ist. Dies führt zu einem Rückstrom der Schmutzpartikel, wodurch die Rückhaltevorrichtung, wie das Auffangsieb, wieder vom Schmutz frei wird. Somit ist auch bei hoher Schmutzbelastung des Gerätes noch ein Umpumpen durch die relativ zur Schmutzmenge gering dimensionierte Siebfläche möglich. Ein in dem Gerät am Boden schwebendes Schmutzteilchen kann beim Abpumpen nach dem Reinigungsvorgang mit in den Ablauf abfließen. Lediglich Partikel an der Wandung und Decke des Gerätes sind so nicht abpumpbar. Die Ablagerung von abgelösten Partikeln an diesen Flächen wird jedoch durch das Auffangsieb in der Reinigerkartusche verhindert. In einer weiteren Ausführungsform ist neben der Rückhaltevorrichtung zusätzlich eine Rückflussverhinderungsvorrichtung innerhalb des Gehäuses angeordnet, um das Zurückfließen von Schmutzpartikeln in das Reinigungssystem zu vermeiden. Beispielsweise kann eine Rückflussverhinderungsvorrichtung ein in dem Reinigungssystem des Geräts integriertes Rückschlagventil umfassen. Im Innenraum des Gerätes und insbesondere in der Reinigerkartusche kann die Rückflussverhinderungsvorrichtung auch als Schmutzfalle durch eine Membran realisiert sein, die sich beim Zurückströmen des Behandlungsgemisches verschließt. Dadurch kann sichergestellt werden, dass Schmutzpartikel innerhalb der Reinigerkartusche gesammelt werden und nach Entfernen der Reinigerkartusche vollständig vom Reinigungssystem abgekoppelt werden. Damit können die hygienischen Bedingungen in dem Reinigungssystem verbessert werden. Weiter erfindungsgemäß wird ein Dampfgarer oder ein Ofen mit einem Reinigungssystem vorgeschlagen, wobei in einem zu reinigendem Innenraum des Gerätes Mittel zur Aufnahme der vorstehend beschriebenen Reinigerkartusche vorgesehen sind.
Dabei kann die vorstehend beschriebene Reinigerkartusche über ein Anschlusselement des Reinigungssystems an eine Wasserversorgung koppelbar sein. Bevorzugt ist die Aufnahme mit dem Anschlusselement der vorstehend beschriebenen Reinigerkartusche verbindbar. Insbesondere ist die vorstehend beschriebene Reinigerkartusche in dem zu reinigenden Innenraum vorgesehen, wobei die Aufnahme mit dem Anschlusselement gekoppelt ist.Preferably, a pump may be clocked. Thus, the retention device in the cleaner cartridge released by a return of dirt particles and it is possible to make the sieve area smaller in relation to the amount of dirt particles. For example, during the cleaning process, when a pump such as a recirculation pump is timed, for example, every 20 seconds so that it does not pump for about 5 seconds during pauses, the debris from the restraint within the purifier cartridge will run into the purge system piping or to the floor the interior of the device, if no backflow prevention device is present. This leads to a return flow of the dirt particles, whereby the restraint device, such as the collecting sieve, is again free from dirt. Thus, even with high contamination of the device still pumping through the relative to the amount of dirt small dimensioned screen surface is possible. A dirt particle floating in the device on the ground can flow into the drain during pumping after the cleaning process. Only particles on the wall and ceiling of the device are not pumpable. However, the deposition of detached particles on these surfaces is prevented by the collecting sieve in the cleaner cartridge. In a further embodiment, in addition to the retaining device, a backflow prevention device is additionally arranged inside the housing, in order to prevent the backflow of dirt particles into the cleaning system. For example, a backflow prevention device may include a check valve integrated in the cleaning system of the device. In the interior of the device and in particular in the cleaner cartridge, the backflow prevention device can also be realized as a dirt trap through a membrane which closes when the treatment mixture flows back. This ensures that dirt particles are collected within the cleaner cartridge and are completely decoupled from the cleaning system after removal of the cleaner cartridge. This can improve the hygienic conditions in the cleaning system. Further according to the invention, a steamer or an oven with a cleaning system is proposed, wherein means are provided for receiving the cleaning cartridge described above in an interior of the device to be cleaned.
In this case, the cleaner cartridge described above can be coupled via a connecting element of the cleaning system to a water supply. Preferably, the receptacle is connectable to the connection element of the cleaner cartridge described above. In particular, the above described cleaner cartridge provided in the interior to be cleaned, wherein the receptacle is coupled to the connection element.
Je nach Ausgestaltung der Reinigerkartusche kann der Ofen oder der Dampfgarer ein Reinigungssystem unterschiedlicher Ausführung umfassen. Bevorzugt umfasst das Reinigungssystem des Gerätes wenigstens eine Wasserversorgung, um Wasser unter Druck in die Reinigerkartusche zu befördern und eine Ablaufleitung, um Wasser aus dem Innenraum entweder zu entsorgen oder über eine Rückführleitung erneut dem Reinigungsvorgang zuzuführen.
Die Wasserversorgung kann etwa über eine Frischwasserleitung oder einen Tank im Gerät bereitgestellt werden. Zur Beförderung des Wassers in die Reinigerkartusche kann weiterhin eine Pumpe vorgesehen sein, die Wasser etwa aus dem Tank oder aus der Frischwasserleitung über Leitungen des Reinigungssystems in die Reinigerkartusche befördert.
In einer weiteren Ausführungsform ist das Anschlusselement drehbar oder statisch ausgebildet. Umfasst die Reinigerkartusche beispielsweise ein statisches Verbindungselement, kann das Anschlusselement des Reinigungssystems, an das die Reinigerkartusche koppelbar ist, drehbar, beispielsweise mit einem Rotor, ausgestaltet sein. Umfasst umgekehrt die Reinigerkartusche beispielsweise ein drehbares Verbindungselement, kann das Anschlusselement im Reinigungssystem, an das die Reinigerkartusche koppelbar ist, nicht drehbar ausgestaltet sein.
Weiterhin kann im Innenraum des Gerätes ein Ablauf mit einem Sieb vorgesehen sein, um Schmutzpartikel zu sammeln und von dem Reinigungssystem fern zu halten. Dieses Sieb fängt die Schmutzpartikel auf und kann nach dem Reinigungsvorgang entleert werden.
In einer Ausführungsform kann die Reinigerkartusche seitlich, oben oder unten im Innenraum des Gerätes angeordnet sein. Vorzugsweise wird die Kartusche in einem mittleren Bereich einer seitlichen, oberen oder unteren einer den Innenraum begrenzenden Wandung des Gerätes angeordnet, um eine möglichst große Reinigungswirkung zu entfalten. Bevorzugt wird die Reinigerkartusche an einer oberen Wandung im Innenraum des Gerätes angeordnet, um die größtmögliche Reinigungswirkung zu entfalten.Depending on the configuration of the cleaner cartridge, the oven or steamer may comprise a cleaning system of different design. Preferably, the cleaning system of the apparatus comprises at least one water supply to convey water under pressure into the purifier cartridge and a drain line to either dispose of water from the interior or to recycle water via a return line.
The water supply can be provided via a fresh water pipe or a tank in the device. For the transport of the water in the cleaner cartridge, a pump may further be provided which conveys water from the tank or from the fresh water line via lines of the cleaning system in the cleaner cartridge.
In a further embodiment, the connection element is rotatable or static. If the cleaner cartridge includes, for example, a static connection element, the connection element of the cleaning system, to which the cleaner cartridge can be coupled, can be designed rotatably, for example with a rotor. Conversely, if the cleaner cartridge includes, for example, a rotatable connection element, the connection element in the cleaning system, to which the cleaner cartridge can be coupled, can not be made rotatable.
Furthermore, a drain can be provided with a sieve in the interior of the device to collect dirt particles and keep away from the cleaning system. This sieve absorbs the dirt particles and can be emptied after the cleaning process.
In one embodiment, the cleaner cartridge can be arranged laterally, above or below in the interior of the device. The cartridge is preferably arranged in a middle region of a lateral, upper or lower wall of the device delimiting the interior in order to develop the greatest possible cleaning effect. Preferably, the cleaner cartridge is arranged on an upper wall in the interior of the device in order to develop the greatest possible cleaning effect.
In einer weiteren Ausführungsform stellt die Wasserversorgung Wasser in einem Druckbereich bereit, der es ermöglicht, beim Versprühen des gelösten Behandlungsmittels auch eine mechanische Reinigungswirkung zu erzielen. Beispielsweise kann die Pumpe einen Druck von 0,1 bar - 4,0 bar, bevorzugt von 0,2 bar - 2,0 bar erzeugen. Um eine bessere Benetzung und Verteilung des Behandlungsmittelgemisches im Innenraum des Dampfgarers oder des Ofens oder dergleichen zu erreichen, kann die Pumpe auch mit wechselnden Drücken arbeiten.
Weiter wird erfindungsgemäß die Verwendung der vorstehend beschriebenen Reinigerkartusche in einem Verfahren zum Reinigen eines Innenraums eines Gerätes vorgeschlagen. Zum Reinigen kann die vorstehend beschriebene Reinigigerkartusche vor Beginn des Reinigungsvorganges an ein Reinigungssystem des Gerätes gekoppelt werden, wenigstens ein Reinigungszyklus gestartet werden und die Reinigerkartusche nach Beendigung des Reinigungsvorganges entnommen werden. Dabei kann die Reinigerkartusche während des Reinigungsvorganges mit Wasser beaufschlagt werden, das mit dem in der Reinigerkartusche aufgenommenen Behandlungsmittel ein Behandlungsmittelgemisch bildet und durch die Sprühöffnungen versprüht wird.
Die im Rahmen der Reinigerkartusche beschriebenen Merkmale gelten entsprechend für das Gerät zum Reinigen eines Innenraums eines Geräts. Umgekehrt gelten die im Rahmen des Geräts zum Reinigen eines verschmutzten Innenraums des Geräts beschriebenen Merkmale entsprechend für die Reinigerkartusche.In a further embodiment, the water supply provides water in a pressure range, which makes it possible to achieve a mechanical cleaning effect when spraying the dissolved treatment agent. For example, the pump can produce a pressure of 0.1 bar - 4.0 bar, preferably 0.2 bar - 2.0 bar. In order to achieve a better wetting and distribution of the treating agent mixture in the interior of the steamer or the oven or the like, the pump can also work with changing pressures.
Further, the invention proposes the use of the above-described cleaning cartridge in a method for cleaning an interior of a device. For cleaning, the cleaner cartridge described above can be coupled to a cleaning system of the device before the start of the cleaning process, at least one cleaning cycle can be started and the cleaner cartridge removed after completion of the cleaning process. In this case, the cleaner cartridge can be subjected to water during the cleaning process, which forms a treatment agent mixture with the recorded in the cleaner cartridge treatment agent and is sprayed through the spray holes.
The features described in the cleaner cartridge apply to the device for cleaning an interior of a device. Conversely, the features described in the unit for cleaning a soiled interior of the unit apply to the cleaner cartridge accordingly.

In der nachfolgenden Beschreibung werden gleiche oder ähnliche Bezugszeichen für gleiche oder ähnliche Komponenten verwendet, wobei in Einzelfällen auf eine wiederholte Beschreibung verzichtet wird. Die Zeichnungen stellen den Gegenstand der Erfindung nur schematisch dar.In the following description, the same or similar reference numerals are used for the same or similar components, in which case a repeated description is omitted. The drawings illustrate the subject matter of the invention only schematically.
In dem Gehäuse 16 ist ein Reinigungssystem 12 vorgesehen, das den Reinigungsvorgang durchführt. Das Reinigungssystem 12 umfasst eine Versorgungsleitung 20, eine Pumpe 22, ein Ventil 24 und ein Steuergerät 26 zum Steuern der Wasserversorgung. Weiterhin kann das Reinigungssystem 12 mit einer Reinigerkartusche 14 gekoppelt werden, die ein Behandlungsmittel bevorratet. Als Behandlungsmittel sind beispielsweise ein Reinigungsmittel und/oder ein Entkalkungsmittel in Form einer Tablette, eines Granulats, einer Flüssigkeit, eines Pulvers oder Blocks, eines Gels in der Reinigerkartusche 14 aufgenommen. Zum Koppeln der Reinigerkartusche 14 an das Reinigungssystem 12 umfasst die Reinigerkartusche 14 ein Verbindungselement 30, dass mit einem Anschlusselement 32 mit der Versorgungsleitung 20 gekoppelt, beispielsweise verschraubt ist.In the
Soll ein Reinigungsvorgang gestartet werden, wird die Reinigerkartusche 14 an das Anschlusselement 32 des Reinigungssystems 12 gekoppelt, und die Wasserzufuhr über das Ventil 24 und die Pumpe 22 von einem Steuergerät 26 gesteuert. Beim Starten des Reinigungsvorganges wird Wasser druckseitig von der Versorgungsleitung 20 in die Reinigerkartusche 14 gepumpt, wodurch sich das Behandlungsmittel im Wasser löst. Ein sich dabei bildendes Behandlungsmittelgemisch wird durch Sprühöffnungen 27 in der Reinigerkartusche 14 in den Innenraum 28 gesprüht.If a cleaning operation to be started, the
Durch Versprühen des gelösten Behandlungsmittelgemisches wird Schmutz auf der Innenseite des Gehäuses 16 im Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens abgetragen. Dabei erfolgt das Abtragen von Schmutz sowohl mechanisch als auch chemisch. Das ablaufende Schmutzwasser wird über einen Ablauf 31 im Boden des Gehäuses 16 abgeleitet. Schmutzpartikel werden in einem Sieb 34, dass dem Ablauf 31 vorgeschaltet ist, gesammelt und sind nach Beendigung des Reinigungsvorganges manuell zu entfernen. Nach Beendigung des Reinigungsvorganges wird die Reinigerkartusche 14 vom Reinigungssystem 12 entfernt und das zu reinigende Gerät 10, beispielsweise ein Dampfgarer oder ein Ofen, steht erneut zur Verfügung.By spraying the dissolved treatment mixture, dirt is removed on the inside of the
Auch in dieser Ausführungsform wird vor dem Start des Reinigungsvorganges eine Reinigerkartusche 14 an das Reinigungssystem 12 gekoppelt. Wasser wird aus dem Wassertank 36 durch die Pumpe 22 bei geöffnetem Ventil 24 in die Reinigerkartusche 14 gepumpt. Das Behandlungsmittel und das Wasser bilden ein gelöstes Behandlungsmittelgemisch, das durch die Sprühöffnungen 27 im Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens verteilt wird. Durch Versprühen des gelösten Behandlungsmittelgemisches wird Schmutz auf der Innenseite des Gehäuses 16 angelöst und abgetragen. Dabei erfolgt das Abtragen von Schmutz sowohl mechanisch als auch chemisch. Das ablaufende Schmutzwasser wird über den Ablauf 31 in die Ablaufleitung 33 oder über einen Rücklauf 38 erneut in die Reinigerkartusche 14 geleitet.Also in this embodiment, a
Um Schmutzpartikel aufzufangen und nicht erneut im Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens zu verteilen, ist in der Reinigerkartusche 14 ein Auffangsieb 40 angeordnet. So werden Schmutzpartikel aus dem Schmutzwasser in der Reinigerkartusche 14 gesammelt. Zusätzlich kann zwischen dem Auffangsieb und der Wasserversorgung eine Rückflussverhinderungsvorrichtung vorgesehen sein, die eine Membran 41 aufweist. Die Membran 41 ist dabei so ausgestaltet, dass Wasser und Schmutzpartikel in einer Pumprichtung passieren können und in der entgegengesetzten Richtung zurückgehalten werden. Die Reinigungslösung kann durch das Sieb und die Sprühöffnungen 52 ablaufen, während die Schmutzpartikel im Auffangsieb zurückgehalten werden. Alternativ zur Membran 40 kann auch ein Rückschlagventil (nicht dargestellt) in der Versorgungsleitung 20 vorgesehen sein.To collect dirt particles and not to redistribute again in the
Nach Beenden des Reinigungsvorganges wird die Reinigerkartusche 14 inklusive der Schmutzpartikel aus dem Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens entfernt. Die
Die Reinigerkartusche 14 umfasst ein Gehäuse 42, das in zylindrischer Form mit einer Umfangsfläche 44, einem Kartuschenkopf 48 und einer Unterseite 46 ausgeführt ist. Der Kartuschenkopf 48 des Gehäuses 42 ist als Aufnahme 50 ausgestaltet, die an die Versorgungsleitung 20 des Reinigungssystems 12 koppelbar ist. In der dargestellten Ausführungsform ist die Aufnahme 50 als einfacher Schraubverschluss ausgestaltet. Entsprechend umfasst die Versorgungsleitung 20 des Reinigungssystems 12 einen komplementär ausgestalteten Schraubverschluss als Anschlusselement 32. Die in
Die Unterseite 46 des Gehäuses 42 umfasst Sprühöffnungen 52, wie in
Die Sprühöffnungen 54 sind derart angeordnet, dass beim Versprühen des gelösten Behandlungsmittelgemisches eine tangentiale Kraftkomponente erzeugt wird. Dazu ist das Gehäuse 42 im mittleren Bereich 56, insbesondere im Bereich der Sprühöffnungen 54 in Richtung der Tangentialen nach innen verformt oder als Einbuchtung geneigt ausgeführt, so dass die Sprühöffnungen 54 Behandlungsmittelgemisch in tangentialer Richtung versprühen. Wird die Reinigerkartusche 14 mit einem rotierbaren Anschlusselement 32 verbunden, erzeugt das Versprühen des gelösten Behandlungsmittelgemisches über die am Umfang 44 angeordneten Sprühöffnungen 54 eine tangentiale Kraftkomponente, die eine Rotationsrichtung 60 der Reinigerkartusche 14 zur Folge hat.The
So kann der Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens gleichmäßig mit dem gelösten Behandlungsmittelgemisch aus der Reinigerkartusche 14 benetzt werden. Um ein Öffnen des Schraubverschlusses zwischen der Aufnahme 50 und dem Anschlusselement 32 des Reinigungssystems 12 zu verhindern, ist die Rotationsrichtung 60 der Kartusche identisch mit einer Einschraubrichtung 62 der Aufnahme 50 gewählt. Die
Die Reinigerkartusche 14 gemäß der
Zur Verbindung der Aufnahme 50 mit dem Anschlusselement 32 des Reinigungssystems 12 umfasst die Aufnahme 50 einen Lagerzapfen 66 sowie einen Schraubverschlusskörper 68 für die Fixierung am Anschlusselement 32 des Reinigungssystems 12. In dieser Ausgestaltung sind die Einschraubrichtung 62 des Schraubverschlusskörpers 68 und die Rotationsrichtung 60 der Reinigerkartusche 14 identisch.To connect the
Der Lagerzapfen 66 wird in das korrespondierende Anschlusselement 32 des Reinigungssystems eingeschraubt. Der Lagerzapfen 66 weist daher am oberen Ende entweder ein Innen- oder ein Außengewinde auf. Der Schraubverschlusskörper 68 seinerseits muss bei Verwendung einer Einwegreinigerkartusche nicht zu öffnen sein und kann fest mit der Reinigerkartusche 14 verbunden sein. Wird hingegen eine Reinigerkartusche 14 eingesetzt, die als Mehrwegkartusche ausgeführt ist, so ist der Schraubverschlusskörper 68 mit einem Gewinde versehen, um den Schraubverschlusskörper 68 von der Reinigerkartusche 14 zur erneuten Befüllung trennen zu können.The bearing

Die
Die Reinigerkartusche 14 umfasst am Umfang 44 des Gehäuses 42 neben den Sprühöffnungen 54 zusätzlich beispielsweise zwei einander gegenüberliegende flügelförmige Rotationskörper 70. Dabei sind die Rotationskörper 70 so ausgestaltet, dass eine gleichmäßige Rotation des Gehäuses 42 der Reinigerkartusche 14 relativ zur Aufnahme 50 möglich ist, da das Drehlager 76 vorgesehen ist. Insbesondere sind die Rotationskörper 70 mit einem dreieckigen Querschnitt ausgestaltet, wobei die Rotationskörper 70 eine gerade Seite 72 in Rotationsrichtung 60 aufweisen. Weiterhin ist eine Seite 74 schräg ausgestaltet. Die Sprühöffnungen 54 sind in der geraden Seite 72 der Rotationskörper 70 angeordnet.The
Die Reinigerkartusche 14 umfasst Sprühöffnungen 78, 80, 54 in unterschiedlichen Bereichen und mit unterschiedlichen Größen am Umfang 44 des Gehäuses 42. Die Sprühöffnungen 78 sind in einem abgeschrägten Bereich 82 des Gehäuses 42 vorgesehen, innerhalb dessen der Umfang des Gehäuses 42 zur Aufnahme 50 hin abnimmt. Die Sprühöffnungen 78 dienen dabei dem gezielten Versprühen von gelöstem Behandlungsmittelgemisch 61 an die Oberseite des Gehäuses 16 im Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens wie in
Im mittleren Bereich 56 des Gehäuses 42 sind zwei Typen von Sprühöffnungen 80, 54 vorgesehen. Die Sprühöffnungen 80 dienen zum gleichmäßigen Benetzen der Seitenwände des Gehäuses 42 des Innenraums 28 des zu reinigenden Dampfgarers 10 oder Ofens, wie in
Die Sprühöffnungen 54 sind in den Rotationskörpern 70 angeordnet und erzeugen zusätzlich die Rotationsbewegung. Durch Versprühen von gelöstem Behandlungsmittelgemisch 61 aus den Sprühöffnungen 54 wird eine Rotationsbewegung erzeugt, die die Reinigerkartusche 14 in eine Rotationsbewegung in Rotationsrichtung 60 versetzt.The
Zusätzlich umfasst die gezeigte Reinigerkartusche 14 ein Auffangsieb 40 im Innern des Gehäuses 42. Dieses hält Schmutzpartikel zurück, so dass nur Behandlungsmittelgemisch 61 oder Reinigungslösung das Auffangsieb 40 passieren kann und über das Auffangsieb 40 in den Innenraum 28 des zu reinigenden Dampfgarers 10 oder Ofens austreten kann. Eine Membran 41 oder eine Schmutzfalle 84 am Einlauf der Reinigerkartusche 14 verhindert das Zurückströmen von Schmutzpartikeln und Behandlungsmittelgemisch 61 zurück zur Pumpe 22 und Wasserversorgung 20, insbesondere wenn die Pumpe 22 getaktet betrieben wird.In addition, the cleaning

Die Reinigerkartusche 14 umfasst weiterhin ein Auffangsieb 40 innerhalb des Gehäuses 42, das Schmutzpartikel aus dem rücklaufenden, gelösten Behandlungsmittelgemisch 61 sammelt. Die Schmutzpartikel werden vom Auffangsieb 40 zurückgehalten, so dass diese nicht durch die Sprühöffnungen 54, 80 erneut im Innenraum 28 verteilt werden. Zusätzlich wird ein Verstopfen der Sprühöffnungen 54, 80 verhindert. Am Ende des Reinigungsvorgangs, bei ausgeschalteter Pumpe 22, sedimentieren die Schmutzpartikel am Boden des Auffangsiebes 40, wobei das in der Reinigerkartusche 14 befindliche gelöste Behandlungsmittelgemisch 61 durch die Sprühöffnungen 54, 80 in den Innenraum 28 austritt und diesen über den Ablauf 31 verlässt.The

Die Planfläche 65 des Gehäuses 42 wird von einem Fluidfilm 90 benetzt. Dieser entsteht dadurch, dass am unteren Ende des Lagerzapfens 66 eine Fluidführung 88 ausgeführt ist, die einen Teilstrom des den Lagerzapfen 66 passierenden Wasserstroms abzweigt und um den Kartuschenkopf 48 herumführt, so dass sich auf der Planfläche 65 besagter Fluidfilm 90 bildet. Dieser dient der Herabsetzung der Reibung zwischen dem Gehäuse 42 der Reinigerkartusche 14 relativ zu dessen Lagerung am Lagerzapfen 66. Auch in der in
Bei der erfindungsgemäß vorgeschlagenen Lösung wird als Behandlungsmittel bevorzugt Reiniger in Feststoffform, sei es in Tablettenform, als Pulver oder Granulat oder in Blockgform oder in Gelform eingesetzt, wobei das Behandlungsmittel innerhalb der Reinigerkartusche 14 innerhalb des Gerätes erst nach dem Start des Reinigungsganges zu einem flüssigen Behandlungsmittel durch Zufuhr von H2O gelöst wird. Dies stellt eine besonders bequeme und sichere Anwendung dar. Bei der erfindungsgemäß vorgeschlagenen Lösung ist die Reinigerkartusche 14 mit mindestens einer Sprühöffnung 54 ausgestattet, die neben der Herbeiführung einer Rotation des Gehäuses 42 der Reinigerkartusche 14 auch zielgerichtet Problembereiche des verschmutzten Innenraumes 28 erreicht. Die Aufnahme 50 ermöglicht eine Verbindung der Reinigerkartusche 14 jeweils vor dem Reinigungsgang mit dem zu reinigenden Dampfgarer 10 oder Ofen wobei nach dem Reinigungsvorgang die Reinigerkartusche 14 aus dem zu reinigenden Gerät 10 entnommen und entsorgt werden kann.In the proposed solution according to the invention is preferably used as a treatment agent cleaner in solid form, be it in tablet form, as a powder or granules or in Blockgform or in gel form, wherein the treatment agent within the
Aufgrund des Umstandes, dass durch die Entfernung der wenigstens einen Sprühöffnung 54 vom Drehpunkt des Gehäuses 42 das Drehmoment einerseits maximiert wird und andererseits die Beibehaltung des Großteiles des Volumens und damit der Masse in der Nähe des Drehpunktes die der Drehung entgegenwirkende Massenträgheit minimiert wird, kann auch bei relativ großvolumigen Reinigerkartuschen 14 eine stabile Drehung erreicht werden.Due to the fact that the removal of the at least one
Des Weiteren zeichnet sich die erfindungsgemäß vorgeschlagene Lösung dadurch aus, dass die wenigstens eine Sprühöffnung 54 das gezielte Versprühen des Behandlungsmittelgemisches 61 ermöglicht, um die mechanische Abtragung zu unterstützen. So können spezielle Sprühöffnungen 78 in der Decke der Reinigerkartusche 14 sowie Sprühöffnungen 52 vorgesehen werden, die von der Unterseite 46 der Reinigerkartusche 14 auf den Boden des zu reinigenden Dampfgarers 10 oder Ofens d.h. auf den zu reinigenden Innenraum 28 begrenzenden Boden gerichtet sind. Eine zielgerichtete Besprühung der Decke ist sinnvoll, ebenso wie ein gezieltes Besprühen des Bodens des Innenraumes 28, da der Bodenbereich des Innenraumes 28 als Sammelpunkt für von den Begrenzungswänden des Innenraumes 28 ablaufenden Schmutz, wie zum Beispiel Fett, Öle oder Zucker dient und einen nur sehr schwer zu reinigenden Bereich darstellt.Furthermore, the solution proposed according to the invention is characterized in that the at least one
Die Reinigerkartusche 14 hat einen Volumenkörper mit einem Volumen, welches je nach Anwendungszweck von 25 ml bis 500 ml, bevorzugt von 50 ml bis 450 ml und besonders bevorzugt von 50 ml bis 300 ml beträgt.The

Unterhalb der ersten Kammer 100 befindet sich eine zweite Kammer 102, die durch einen Verschluss 104 verschlossen ist, der ein retardierendes Freigeben des in der zweiten Kammer vorliegenden Behandlungsmittels oder des dort vorliegenden Behandlungsmittelgemisches ermöglicht. Der Verschluss 104, der eine am Boden der zweiten Kammer ausgebildete Öffnung verschließt, ist bevorzugt aus Wachs oder einer anderen bei einer Temperaturerhöhung schmelzenden oder sich besser in Behandlungsmittelgemisch oder Wasser lösenden Substanz gebildet. Abhängig von der Temperatur, die im Innenraum 28 des zu reinigenden Geräts 10 herrscht, schmilzt oder löst sich der Verschluss 104 und gibt die sich an der Unterseite der zweiten Kammer 102 befindende Öffnung frei, wie in
Aufgrund der abhängig von den im Innenraum 28 herrschenden Temperaturen ist ein Schmelzen des Verschlusses 104, der vorzugsweise aus Wachs oder einer anderen bei einer Temperaturerhöhung schmelzenden oder sich besser in Behandlungsmittelgemisch oder Wasser lösenden Substanz gefertigt ist, möglich, so dass ein verzögertes Freisetzen des in der zweiten Kammer 102 der Zwei-Kammerkartusche 98 bevorrateten Behandlungsmittelgemisches erfolgen kann.Due to the temperatures prevailing in the interior 28, melting of the
Während das in der ersten Kammer 100 bevorratete Behandlungsmittel direkt mit dem Reinigungssystem 12 verbunden ist, enthält die zweite Kammer 102 ein davon verschiedenes Behandlungsmittel und hat keine Verbindung zur ersten Kammer 100. Das in der ersten Kammer 100 enthaltene Behandlungsmittel wird unmittelbar nach Start des Programmes gelöst, das Behandlungsmittelgemisch 61 bildet sich und tritt über die Sprühöffnungen 54 in den Innenraum 28 des zu reinigenden Gerätes 10 ein. Die Freisetzung des in der zweiten, untenliegenden Kammer 102 bevorrateten Behandlungsmittels erfolgt dann, wenn eine gewünschte Temperatur erreicht wird, der durch Wachs gebildete Verschluss 104 schmilzt und das Produkt aus der dann freigegebenen Öffnung 106 in vertikale Richtung in den Innenraum 28 des zu reinigenden Gerätes eintritt.
Das zu reinigende Gerät kann zwischen der Wirkungsphase des ersten Behandlungsmittelgemisches aus der ersten Kammer 100 und der Wirkungsphase des zweiten Behandlungsmittelgemisches aus der zweiten Kammer 102 gespült werden.
Eine solche Zwei-Kammer Kartusche kann beispielsweise ein erstes Behandlungsmittel wie z.B. ein alkalisches Reinigungsmittel in der ersten Kammer 100 und ein weiteres alkalisches Reinigungsmittel oder ein saures Entkalkungsmittel in der zweiten Kammer 102 aufweisen. Hierdurch kann das zu reinigende Gerät 10 innerhalb eines Reinigungsprogramms des Reinigungssystem 12 entweder gereinigt und entkalkt oder durch zwei aufeinanderfolgende Reinigungen tiefengereinigt werden.While the treating agent stored in the
