Description

Die Erfindung betrifft ein UV-Reinigungsmodul für eine gewerblich nutzbare Küchenluftreinigungsanlage, mit einem Flammschutzfilter, mit mindestens einem UV-Strahler zur Kaltverbrennung eines Öl- und/oder Fettnebels im Küchendunst. Das UV-Reinigungsmodul, mit einem quaderförmigen Modulgehäuse mit einem Innenraum, in dem ein UV-Lichtmodul mit mindestens einem UV-Strahler aufgenommen ist, ist angepasst für den Einbau in oder den Anbau an ein Gehäuse der Küchenluftreinigungsanlage. Das Modulgehäuse weist an einem unteren Gehäuseabschnitt unten eine Lufteintrittsöffnung in den Innenraum, an einem oberen Gehäuseabschnitt oben eine Luftaustrittsöffnung aus dem Innenraum und an einem dazwischen angeordneten mittleren Gehäuseabschnitt an einer zugänglichen Seitenwand einen Zugang zu dem Innenraum auf, der mit einer den Zugang freigebenden abdichtenden Zugangsabdeckung verschlossen ist, wobei das UV-Lichtmodul in dem mittleren Gehäuseabschnitt über Führungselemente lösbar befestigt ist.The invention relates to a UV cleaning module for a commercially useful kitchen air cleaning system, with a flame retardant filter, with at least one UV lamp for cold combustion of oil and / or grease mist in kitchen art. The UV cleaning module, with a cuboid module housing with an interior, in which a UV light module is accommodated with at least one UV lamp, is adapted for installation in or attachment to a housing of the kitchen air cleaning system. The module housing has at a lower housing portion below an air inlet opening into the interior, at an upper housing portion above an air outlet opening from the interior and an intermediate housing portion disposed therebetween on an accessible side wall access to the interior, with an access releasing sealing access cover is closed, wherein the UV light module is releasably secured in the central housing portion via guide elements.

Küchenluftreinigungsanlagen sind dazu bestimmt, den von einem Koch-, Brat- oder Grillgerät erzeugten Küchendunst aus der Küchenluft zu entfernen. Der Küchendunst, der die Küchenluft verschmutzt, umfasst unerwünschte Schwebstoffe wie beispielsweise fein verteilte Öl- oder Fetttröpfchen, Geruchsstoffe, Feststoffpartikel oder dergleichen. Bekannte gewerbliche Küchenluftreinigungsanlagen weisen in der Regel eine Dunstabzugshaube auf, der verschmutzte Küchenluft mittels einer Abzugseinrichtung zugeführt wird, sowie einen darauf folgenden Aerosolfilter mit einem in Strömungsrichtung danach angeordneten UV-Lichtmodul. Das Aerosolfilter filtert aus der durchgeleiteten Küchenluft feste oder flüssige Schwebeteilchen bis zu einer bestimmten Größe aus. Kleinere Schwebeteilchen können den Aerosolfilter als Schwebestaub bzw. Nebel passieren. Ohne das UV-Lichtmodul, das insbesondere die nicht ausgefilterten Öl- oder Fettanteile kalt verbrennt, würden sich diese an der Abzugseinrichtung sowie an dem Abluftschacht der Küchenluftreinigungsanlage ablagern. Derartige Ablagerungen müssen aus Brandschutzgründen regelmäßig entfernt werden, was mit erheblichem Aufwand verbunden ist.Kitchen air cleaning systems are designed to remove the cooking odor produced by a cooking, frying or grilling device from the kitchen air. The kitchen fume that soils the kitchen air includes undesirable particulates such as finely divided oil or fat droplets, odorants, solid particles, or the like. Well-known commercial kitchen air cleaning systems generally have an extractor hood, which is supplied to dirty kitchen air by means of a take-off device, and a subsequent aerosol filter with a downstream arranged in the flow direction UV light module. The aerosol filter filters solid or liquid airborne particles up to a certain size from the kitchen air. Smaller suspended particles can pass through the aerosol filter as dust or fog. Without the UV light module, which in particular burns the unfiltered oil or fat components cold, they would deposit on the extraction device and on the exhaust duct of the kitchen air cleaning system. Such deposits must be removed regularly for fire protection reasons, which is associated with considerable effort.

In Hotels, Kantinen und Fast-Food-Gaststätten werden in Küchenluftreinigungsanlagen zunehmend UVC-C-Strahler zum Abbau der fetthaltigen, organischen und geruchstragenden Stoffe eingesetzt. Das von dem UV-Lichtmodul abgestrahlte UV-Licht erzeugt Ozon, welches mit den verbliebenen Öl- oder Fettpartikeln reagiert. Dies führt zum Einen dazu, dass öl- oder fetthaltige Ablagerungen in der Küchenluftreinigungsanlage weitgehend vermieden werden und bringt zum Anderen auch den positiven Effekt mit sich, dass eine deutliche Geruchsreduzierung erzielt und zudem die Reinigungskosten erheblich reduziert werden. Die gereinigte Küchenluft kann anschließend ohne weitere Maßnahmen ins Freie abgeleitet oder der Raumluft wieder zugeführt werden, falls notwendig über einen Aktivkohlefilter.In hotels, canteens and fast-food restaurants, kitchen air-cleaning systems are increasingly using UVC-C lamps to degrade fatty, organic and odor-carrying substances. The UV light emitted by the UV light module generates ozone, which reacts with the remaining oil or fat particles. This leads to the fact that oil or greasy deposits in the kitchen air cleaning system are largely avoided and on the other hand also brings the positive effect that a significant reduction in odor achieved and also the cleaning costs are significantly reduced. The cleaned kitchen air can then be discharged into the open without further measures or returned to the room air, if necessary via an activated carbon filter.

Die am Markt verfügbaren UV-C-Abluftreinigungsanlagen sind jedoch auch mit verschiedenen Nachteilen behaftet. Häufig wird bei herkömmlichen UV-Systemen die Strahlenbelastung des Küchenpersonals nicht vollkommen und nachhaltig verhindert. Außerdem funktionieren derartige Systeme in der Regel nur mit geeigneten Aerosolabscheidern und Zwischenfiltern. Auch führt das vom UV-Licht erzeugte Ozon mancherorts zu Genehmigungsproblemen für die Betreibung der Küchenluftreinigungsanlage durch die Behörden. Zudem ist bei diesen Systemen die Wartung sehr komplex. Der durch Alterung bzw. starke Verschmutzung notwendige Strahleraustausch ist meist sehr kompliziert und kann daher meist nur durch Servicekräfte des Herstellers durchgeführt werden. Die diesbezügliche Wartung der Küchenluftreinigungsanlage kann auch nicht während des Betriebes durchgeführt werden, so dass der Betrieb für die Reinigung unterbrochen werden muss. Der Betrieb der Luftreinigungsanlage ohne oder mit einem nicht ordnungsgemäß funktionierendem UV-Modul führt zu unkontrollierten Ablagerungen, die mit der Zeit zu einem Druckabfall im Rohrsystem und damit zu einem erhöhten Energieverbrauch führen können. Auch reagiert der Ventilator der Abzugseinrichtung durch Ablagerungen auf den Lüfterschaufeln mit einer kürzeren Lebensdauer. Ein ungenügender Unterdruck im Rohrsystem hat zur Folge, dass sich schnell ein Öl- oder Fettfilm im Raum an Decken, Wänden, Böden sowie auf Einrichtungen und Gegenständen der Küche bildet. Dies führt wiederum zu einem erhöhten Reinigungsaufwand und damit zu erhöhten Betriebskosten. Die weitaus größere Gefahr geht jedoch von einem möglichen Fettbrand aus. Die Entzündungstemperatur alter Fette oder Öle liegt je nach Alter und/oder Beschaffenheit bei etwa 200 °C. Bei einem derartigen Brand können die Flammen über den Abluftkanal das komplette Gebäude zerstören. Außerdem können bei ungenügender Absaugung des Küchendunstes die durch den Raum ziehenden öl- oder fetthaltigen Schwaden die Gesundheit des Küchenpersonals gefährden. Zum Stand der Technik wird beispielhaft auf die Druckschriften US 2004/211321 A1 , WO 01/039868 A1 und ES 2 169 007 A1 verwiesen.However, the UV-C exhaust air purification systems available on the market also have various disadvantages. Frequently, in conventional UV systems, the radiation exposure of the kitchen staff is not completely and sustainably prevented. In addition, such systems usually only work with suitable aerosol separators and intermediate filters. Also, the ozone generated by UV light leads in some places to licensing problems for the operation of the kitchen air purification system by the authorities. In addition, the maintenance is very complex in these systems. The by aging or heavy pollution necessary replacement of the lamp is usually very complicated and therefore can usually only be carried out by service staff of the manufacturer. The maintenance of the kitchen air cleaning system in this regard can not be performed during operation, so that the operation for cleaning must be interrupted. Operation of the air purifier without or with a malfunctioning UV module will result in uncontrolled deposits which, over time, can lead to a pressure drop in the piping system and therefore increased energy consumption. Also, the fan of the discharge device reacts by deposits on the fan blades with a shorter life. Insufficient underpressure in the piping system results in the rapid formation of an oil or grease film in the room on ceilings, walls, floors, as well as on kitchen equipment and objects. This in turn leads to an increased cleaning effort and thus to increased operating costs. The far greater danger, however, is based on a possible fat burning. Depending on the age and / or condition, the ignition temperature of old fats or oils is around 200 ° C. In such a fire, the flames over the exhaust duct can destroy the entire building. In addition, with insufficient extraction of kitchen artishness, the oily or greasy swaths passing through the room can endanger the health of the kitchen staff. The state of the art is exemplified in the documents US 2004/211321 A1 . WO 01/039868 A1 and ES 2 169 007 A1 directed.

Weitere vorteilhafte Ausgestaltungen sind den rückbezogenen Ansprüchen zu entnehmen.This object is achieved by a UV cleaning module having the features of claim 1. Further advantageous embodiments can be found in the dependent claims.

Das erfindungsgemäße UV-Reinigungsmodul weist ein Modulgehäuse mit einer im wesentlichen quaderförmigen Kontur auf und ist außen an das Gehäuse einer bestehenden Küchenluftreinigungsanlage ohne UV-Fett- und/oder Ölverbrennung anbaubar oder in ein solches Gehäuse einbaubar. Es weist an seiner Unterseite an einem unteren Gehäuseabschnitt eine Eintrittsöffnung in und an seiner Oberseite an einem oberen Gehäuseabschnitt eine Austrittsöffnung aus dem Innenraum des Modulsgehäuses für die Küchenluft auf. Zwischen dem unteren und dem oberen Gehäuseabschnitt ist ein mittlerer Gehäuseabschnitt angeordnet, an dem an einer zugänglichen Seitenwand ein Zugang zu dem Innenraum des Modulgehäuses vorgesehen ist. Der Zugang ist mit einer den Zugang freigebenden abdichtenden Zugangsabdeckung verschlossen, die mit der entsprechenden Seitenwand abnehmbar oder schwenkbeweglich verbunden ist, wobei die Zugangsabdeckung einen Teil des mittleren Gehäuseabschnitts des Modulgehäuses bildet. Das UV-Lichtmodul ist in dem mittleren Gehäuseabschnitt über Führungselemente lösbar insbesondere einschiebbar befestigt ist. Dazu sind an dem UV-Modul und dem Modulgehäuse jeweils Führungselemente angeordnet, die komplementär zueinander ausgebildet sind. Die Zugangsabdeckung kann dabei von einem losen Zugangsdeckel oder von einer vorzugsweise vertikal angelenkten Zugangsklappe gebildet sein und ist mit der Seitenwand verriegelbar. Dabei kann das UV-Lichtmodul an einer dem Innenraum zugeordneten Innenseite der Zugangsklappe oder des Zugangsdeckels oder an einer Innenseite des unteren, mittleren und/oder oberen Gehäuseabschnittes lösbar befestigt sein. Vorzugsweise ist das UV-Lichtmodul an der jeweiligen Innenseite einschiebbar oder einhängbar befestigt. Das UV-Lichtmodul bildet zusammen mit dem Modulgehäuse das erfindungsgemäße UV-Reinigungsmodul. Erfindungsgemäß ist bei dem Modulgehäuse des UV-Reinigungsmoduls der untere Gehäuseabschnitt als unterer modularer Gehäuseeinsatz und/oder der obere Gehäuseabschnitt als oberer modularer Gehäuseeinsatz ausgebildet, wobei die Gehäuseeinsätze mit dem mittleren Gehäuseabschnitt fest verbunden, vorzugsweise verschraubt sind. Das UV-Reinigungsmodul weist auch einen Flammschutzfilter auf. Dabei weist die Austrittsöffnung des Modulgehäuses sich in Richtung der Eintrittsöffnung erstreckende Luftleitbleche auf. Die sich an der Austrittsöffnung des Modulgehäuses in Richtung der Eintrittsöffnung erstreckende Luftleitbleche leiten die Küchenluft, die zur Fett- bzw. Ölverbrennung des Küchendunstes um die UV-Strahler des UV-Lichtmoduls herum geleitet wird, nach der Bestrahlung mit UV-Licht direkt zu der Austrittsöffnung. Die Luftleitbleche verhindern einen Stau sowie Verwirbelungen der bestrahlten Küchenluft und damit etwaige Ablagerungen in der Umgebung der Austrittsöffnung des UV-Reinigungsmoduls.The UV cleaning module according to the invention has a module housing with a substantially cuboid contour and is outside of the housing a existing kitchen air purification system without UV-fat and / or oil burning attachable or can be installed in such a housing. It has on its underside at a lower housing portion an inlet opening in and at its upper side on an upper housing portion an outlet opening from the interior of the module housing for the kitchen air. Between the lower and the upper housing portion, a central housing portion is arranged, on which an accessible side wall access to the interior of the module housing is provided. The access is closed by an access-releasing sealing access cover which is removably or pivotally connected to the corresponding side wall, the access cover forming part of the central housing portion of the module housing. The UV light module is detachably fastened in particular in the middle housing section via guide elements, in particular being pushed in. For this purpose, each guide elements are arranged on the UV module and the module housing, which are complementary to each other. The access cover can be formed by a loose access cover or by a preferably vertically hinged access flap and can be locked to the side wall. In this case, the UV light module can be detachably fastened to an inner side of the access flap or access cover assigned to the interior or to an inner side of the lower, middle and / or upper housing section. Preferably, the UV light module is attached to the respective inner side inserted or suspended. The UV light module together with the module housing forms the UV cleaning module according to the invention. According to the invention, in the case of the module housing of the UV cleaning module, the lower housing section is designed as a lower modular housing insert and / or the upper housing section as an upper modular housing insert, wherein the housing inserts are firmly connected, preferably screwed, to the central housing section. The UV cleaning module also has a flame retardant filter. In this case, the outlet opening of the module housing in the direction of the inlet opening extending air baffles. The at the outlet opening of the module housing in the direction of the inlet opening extending air baffles The kitchen air, which is routed around the UV lamps of the UV light module for the purpose of burning off the fats or oils of kitchen fumes, leads directly to the outlet opening after irradiation with UV light. The baffles prevent congestion and turbulence of the irradiated kitchen air and thus any deposits in the vicinity of the outlet opening of the UV cleaning module.

Bei einer bevorzugten Ausführungsform der UV-Reinigungsmoduls ist an dem unteren Gehäuseabschnitt innenliegend ein einschiebbarer die Lufteintrittsöffnung überdeckender Flammschutzfilter angeordnet, der bei geöffnetem Zugang in das Modulgehäuse einsetzbar bzw. aus diesem entfernbar ist. Dazu weist die Eintrittsöffnung oder das Modulgehäuse auf der der Austrittsöffnung gegenüber liegenden Seite Befestigungsmittel für den dem UV-Lichtmodul lösbar vorschaltbaren Flammschutzfilter auf. Die Befestigungsmittel können beispielsweise als Führungsschienen oder als Verrastungen ausgebildet sein. Die Verwendung des Flammschutzfilters ist optional und davon abhängig, welche Filtertypen bereits vor der Eintrittsöffnung des Modulgehäuses in der Küchenluftreinigungsanlage vorgesehen sind. Der Flammschutzfilter ist vorzugsweise durch den geöffneten Zugang zu dem mittleren Gehäuseabschnitt in das Modulgehäuse einsetzbar bzw. aus diesem entfernbar, ohne das der UV-Lichtmodul entfernt wird. Dies erleichtert die Prüfung und die Reinigung bzw. den Ersatz des Flammschutzfilters falls erforderlich.In a preferred embodiment of the UV cleaning module, a retractable flameproofing filter covering the air inlet opening is arranged on the inside of the lower housing section, said flameproofing filter being insertable into or removable from the module housing when the access opening is open. For this purpose, the inlet opening or the module housing on the side opposite the outlet opening side fastening means for the UV light module releasably upstream flame retardant filter. The fastening means may be formed, for example, as guide rails or as latches. The use of the flameproof filter is optional and depends on which filter types are already provided in front of the inlet opening of the module housing in the kitchen air cleaning system. The flame retardant filter is preferably insertable into or removed from the module housing through the open access to the central housing portion without removing the UV light module. This facilitates testing and cleaning or replacement of the flameproof filter if necessary.

Das erfindungsgemäße UV-Lichtmodul, das zum Einbau in eine Küchenluftreinigungsanlage vorgesehen ist und mindestens einen UV-Strahler zur Kaltverbrennung eines Öl- und/oder Fettnebels im abgezogenen Küchendunst aufweist, ist in einem Gehäuse der Küchenluftreinigungsanlage anordenbar, das für UV-Licht undurchlässig ausgebildet ist und einen Strömungskanal aufweist, durch den der Küchendunst von einer Absaugung abgezogen wird. Derartige Gehäuse sind in der Regel aus korrosionsbeständigen, einfach zu reinigenden und abgekanteten Edelstahlblechen hergestellt. Das UV-Lichtmodul ist insbesondere in das Gehäuse einschiebbar ausgebildet. Es weist seitliche Halterungen zur Aufnahme des UV-Strahlers auf, die den UV-Strahler mindestens an einem Ende aufnehmen und die über Quertraversen miteinander starr verbunden sind.The UV light module according to the invention, which is intended to be installed in a kitchen air cleaning system and has at least one UV radiator for cold combustion of an oil and / or grease mist in the extracted kitchen art, can be arranged in a housing of the kitchen air cleaning system, which is impermeable to UV light and a flow channel through which the kitchen fume is extracted from a suction. Such housings are usually made of corrosion-resistant, easy to clean and folded stainless steel sheets. The UV light module is formed in particular insertable into the housing. It has lateral brackets for Recording of the UV lamp, which receive the UV lamp at least at one end and are rigidly connected to each other via crossbeams.

Die Halterungen können beispielsweise bearbeitete Bleche sein. Die Traversen können an sich eine beliebige Querschnittsform aufweisen, d. h. beispielsweise als Blechstreifen, Profil oder Stange mit einer an die UV-Strahler angepassten Länge ausgebildet sein. Günstig ist es, wenn die Traversen als Strömungsleitbleche wirken und vorzugsweise in Strömungsrichtung der zu reinigenden Küchenluft direkt vor dem jeweiligen UV-Strahler angeordnet sind und diese um den UV-Strahler herum leiten. Damit wird eine frühzeitige Verschmutzung des mindestens einen UV-Strahlers vermieden. Die Halterungen weisen Ausnehmungen auf, in die sich die Enden des UV-Strahlers erstrecken. Dabei genügt es in der Regel, wenn der UV-Strahler einseitig an einer der Halterungen befestigt ist, da die Halterungen mit den Traversen ein stabiles Gestell bilden. Das andere Ende des UV-Strahlers kann, muss aber nicht an der anderen Halterung fixiert oder dort geführt sein.The brackets may be, for example, processed sheets. The trusses may in themselves have any cross-sectional shape, i. H. For example, be designed as a metal strip, profile or rod with a matched to the UV lamp length. It is advantageous if the trusses act as flow baffles and are preferably arranged in the flow direction of the kitchen air to be cleaned directly in front of the respective UV radiator and guide them around the UV radiator. This prevents premature contamination of the at least one UV emitter. The brackets have recesses into which extend the ends of the UV lamp. It is usually sufficient if the UV lamp is attached to one side of one of the brackets, since the brackets form a stable frame with the trusses. The other end of the UV lamp can, but does not have to be fixed or guided on the other holder.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen UV-Lichtmoduls ist an mindestens einer Halterung auf der dem UV-Strahler abgewandten Seite eine abgedichtete Anschlusssteckverbindung direkt an der Halterung oder an einem an der Halterung befestigten Verteilergehäuse angeordnet, das mit der Halterung dichtend verbunden ist. In dem Verteilergehäuse ist eine elektrische Verbindung zwischen dem UV-Strahler und der Anschlusssteckverbindung hergestellt. Die Anschlusssteckverbindung umfasst ein Steckerteil und ein Gegensteckerteil, das von dem Steckerteil lösbar und wieder mit diesem verbindbar ist. Das Gegensteckerteil ist für die Kontaktierung eines elektrischen Anschlusskabels vorgesehen, das von einer Steuerung für das UV-Lichtmodul ausgeht, so dass die elektrische Verbindung zu dem UV-Lichtmodul einfach und schnell trennbar und wiederherstellbar ist.In a preferred embodiment of the UV light module according to the invention, a sealed connection plug connection is arranged directly on the holder or on a distributor housing fastened to the holder on at least one holder on the side facing away from the UV emitter, which is sealingly connected to the holder. In the distributor housing, an electrical connection between the UV lamp and the connection plug connection is made. The connection plug connection comprises a plug part and a mating plug part, which can be detached from the plug part and can be connected to it again. The mating connector part is provided for contacting an electrical connection cable, which starts from a controller for the UV light module, so that the electrical connection to the UV light module can be easily and quickly separated and restored.

Vorzugsweise weist zumindest die Halterung, an der der UV-Strahler unbeweglich befestigt ist, ein elastisches Lager für den UV-Strahler auf. Das elastische Lager kann zwei abdichtende Ringe oder Scheiben aufweisen, die an den Flachseiten der Halterungen anliegen. Die jeweils zwei Ringe oder Scheiben können auch durch ein einziges Formteil ersetzt werden, das ring- oder scheibenförmig mit einer außen umlaufenden Ringnut ausgebildet ist. Die elastischen Lager können den UV-Strahler vor Vibrationen schützen, so dass es sinnvoll erscheint, diesen an beiden Enden elastisch aufzunehmen. Das Material für die elastischen Lager muss im Hinblick auf UV-Beständigkeit ausgewählt werden. Des Weiteren ist es vorteilhaft ein lichtundurchlässiges Material zu verwenden, da damit seitlich an den Halterungen kein UV-Licht austreten kann.Preferably, at least the holder to which the UV emitter is fixed immovably, an elastic bearing for the UV lamp on. The elastic bearing may have two sealing rings or discs on the flat sides rest the brackets. The two rings or discs can also be replaced by a single molded part, which is formed ring-shaped or disc-shaped with an outer circumferential annular groove. The elastic bearings can protect the UV emitter from vibrations, so that it makes sense to take this elastically at both ends. The material for the elastic bearings must be selected for UV resistance. Furthermore, it is advantageous to use an opaque material since no UV light can escape laterally from the holders.

Bei einer Ausführung der Erfindung ist das UV-Lichtmodul modular erweiterbar. Dabei kann die Anzahl der UV-Strahler des UV-Lichtmoduls entsprechend der benötigten Leistung verändert werden. Es können sowohl UV-Strahler entfernt wie auch ergänzt werden. Die Halterungen sowie das Verteilergehäuse sind entsprechend vorbereitet bzw. ausgebildet.In one embodiment of the invention, the UV light module is modular expandable. In this case, the number of UV lamps of the UV light module can be changed according to the required power. Both UV lamps can be removed and supplemented. The brackets and the distributor housing are prepared or formed accordingly.

Das vorgeschlagene UV-Lichtmodul ist zudem vorteilhafterweise wasserdicht und spülmaschinenfest ausgebildet. Es kann nach der Entnahme aus dem Modulgehäuse in einer Gewerbespülmaschine problemlos in kurzer Zeit gereinigt und getrocknet werden, ohne dass es beschädigt wird. Auf diese Weise ist eine gründliche Reinigung sichergestellt.The proposed UV light module is also advantageously waterproof and dishwasher safe. It can be easily cleaned and dried in a short time after removal from the module housing in a commercial dishwasher, without it being damaged. This ensures thorough cleaning.

Vorzugsweise ist das UV-Lichtmodul bei einer günstigen Ausführungsform mittels den Halterungen an der Innenseite des mittleren Gehäuseabschnittes befestigt. Dazu können an den Halterungen schienenförmige oder hakenförmige Abkantungen, Bohrungen mit oder ohne Gewinde bzw. andere geeignete Ausnehmungen oder Stehbolzen mit oder ohne Gewinde angeordnet sein. Eine einfache mögliche Befestigungsart für die Halterungen des UV-Lichtmoduls an der Innenseite des mittleren Gehäuseabschnittes umfasst eine Schraubverbindung, die einfach herstellbar und lösbar ist. Die Schraubverbindung kann einen Gewindebolzen mit einer Vierkant-, Sechskant-, Flügel- oder Rändelmutter aufweisen oder eine Schraube mit einem geeigneten Kopf, der eine Bohrung mit Innengewinde zugeordnet ist. Alternativ kann die Innenseite beispielsweise hinterschnittene Schiebeführungen oder Tragehaken für dasPreferably, the UV light module is attached in a favorable embodiment by means of the brackets on the inside of the central housing portion. For this purpose, rail-shaped or hook-shaped bends, holes with or without thread or other suitable recesses or studs with or without thread can be arranged on the holders. A simple possible method of attachment for the holders of the UV light module on the inside of the central housing section comprises a screw connection which is easy to manufacture and detach. The screw can have a threaded bolt with a square, hexagon, wing or knurled nut or a screw with a suitable head, which is associated with a bore with internal thread. Alternatively, the inside, for example, undercut sliding guides or hooks for the

Begünstigt werden Führungselemente, die schienenartig ausgebildet sind und damit eine Führung bilden.Have UV light module, which interact with correspondingly complementary trained rails, hooks, bolts or the like of the UV light module. Favored are guide elements which are rail-like and thus form a guide.

Bei einer vorteilhaften Ausführungsform der Erfindung weist das UV-Lichtmodul und/oder die Innenseite des Modulgehäuses bzw. der Zugangsabdeckung Verriegelungsmittel zur Lagesicherung und Festlegung des UV-Lichtmoduls auf. Die Ausbildung der Verriegelungsmittel ist abhängig von der Position und Anordnung und Ausgestaltung der Führungselemente für das UV-Modul. Sie sollen zuverlässig ein ungewolltes Verschieben gegenüber oder ein unbeabsichtigtes Lösen des UV-Lichtmoduls von dem Modulgehäuse oder der Zugangsabdeckung verhindern. Günstig ist es, wenn die Verriegelungsmittel beispielsweise federbeaufschlagt sind und die Verriegelung automatisch vornehmen, sobald das UV-Lichtmodul eine bestimmte Position eingenommen hat. Auch das Lösen der Verriegelung ist in diesem Fall besonders einfach vorzunehmen.In an advantageous embodiment of the invention, the UV light module and / or the inside of the module housing or the access cover has locking means for securing the position and fixing the UV light module. The design of the locking means is dependent on the position and arrangement and design of the guide elements for the UV module. They are intended to reliably prevent unintentional shifting or inadvertent release of the UV light module from the module housing or access cover. It is advantageous if the locking means are, for example spring-loaded and make the lock automatically when the UV light module has taken a certain position. Also, the release of the lock is particularly easy to do in this case.

Das Modulgehäuse des erfindungsgemäßen UV-Reinigungsmoduls ist günstigerweise aus abgekanteten korrosionsbeständigen und einfach zu reinigenden Edelstahlblechen hergestellt und modular aufgebaut. Es besteht vorzugsweise aus modular ausgebildeten unteren und oberen Gehäuseabschnitten, die idealerweise mit einem standardmäßigen mittleren Gehäuseanschnitt fest oder lösbar verbunden sind. Der mittlere Gehäuseabschnitt ist an das aufzunehmende UV-Lichtmodul angepasst. Der untere und der obere Gehäuseabschnitt können in der äußeren Kontur und/oder in der Größe bzw. in der Form der Eintrittsöffnung respektive der Austrittsöffnung variiert werden, ohne dass der mittlere Gehäuseabschnitt verändert wird. Damit ist auf einfache Weise eine Adaptierung des Modulgehäuses mit dem darin aufgenommenen UV-Modul an verschiedene Küchenluftreinigungsanlagen möglich.The module housing of the UV cleaning module according to the invention is conveniently made of folded corrosion-resistant and easy-to-clean stainless steel sheets and modular. It preferably consists of modular lower and upper housing sections, which are ideally fixed or detachably connected to a standard central housing section. The middle housing section is adapted to the male UV light module. The lower and the upper housing section can be varied in the outer contour and / or in the size or in the shape of the inlet opening and the outlet opening, respectively, without the central housing section being changed. This is a simple way of adapting the module housing with the recorded therein UV module to various kitchen air cleaning systems possible.

Bei einer Ausführungsform der Erfindung weist der untere Gehäuseabschnitt einen unteren Gehäuseeinsatz mit einer Eintrittsöffnung für den mit Öl oder Fett belasteten Küchendunst und der obere Gehäuseabschnitt einen
oberen Gehäuseeinsatz mit einer Austrittsöffnung für den gereinigten, d. h. öl- bzw. fettfreien Küchendunst auf. Der obere Gehäuseeinsatz ist abhängig von der Ausbildung entweder mit dem oberen Gehäuseabschnitt und/oder dem mittleren Gehäuseabschnitt verschraubt. Er kann jedoch auch mit diesen vernietet oder verschweißt sein. Gleiches gilt sinngemäß für den unteren Gehäuseeinsatz.In one embodiment of the invention, the lower housing portion has a lower housing insert with an inlet opening for the oil or grease loaded kitchen art and the upper housing portion a
upper housing insert with an outlet opening for the purified, ie oil or grease-free kitchen art. The upper housing insert is screwed depending on the training either with the upper housing portion and / or the central housing portion. However, it can also be riveted or welded with these. The same applies mutatis mutandis to the lower housing use.

Bei einer Variante des erfindungsgemäßen UV-Reinigungsmoduls weist der mittlere Gehäuseabschnitt eine von dem UV-Lichtmodul abgetrennte abgedichtete Kammer für eine vorzugsweise einschiebbare Steuerung für die Ansteuerung des UV-Lichtmoduls auf. Die Steuerung ist beispielsweise über ein elektrisches Anschlusskabel mit dem Gegensteckerteil der Anschlusssteckverbindung elektrisch verbunden, wobei das Gegensteckerteil einfach und schnell mit dem an dem UV-Lichtmodul unlösbar befestigten Steckerteil der Anschlusssteckverbindung verbunden oder von diesem getrennt werden kann. Die abgedichtete Kammer schützt die Steuerung vor Fett- und/oder Ölablagerungen und vor hohen Temperaturen, die von den UV-Strahler und dem Verbrennungsprozess verursacht werden. Die Steuerung kann bei Störungen oder Ausfall problemlos ausgetauscht werden.In a variant of the UV cleaning module according to the invention, the middle housing section has a sealed chamber separated from the UV light module for a preferably insertable control for controlling the UV light module. The control is for example via an electrical connection cable electrically connected to the mating connector part of the connection plug-in connection, wherein the mating connector part can be easily and quickly connected to or disconnected from the plug-in part of the connection plug connection permanently attached to the UV light module. The sealed chamber protects the controller from grease and / or oil deposits and high temperatures caused by the UV lamps and the combustion process. The controller can be replaced easily in case of failure or failure.

Für einen sicheren Betrieb und um Funktionsprobleme der Küchenluftreinigungsanlage jederzeit zu erkennen und entsprechende Meldungen auszugeben, wird deren ordnungsgemäße Funktion über das Modulgehäuse und das UV-Lichtmodul überwacht. Hierfür kann beispielsweise eine intelligente Steuerung mit einer entsprechenden Software und zugeordneten Sensoren verwendet werden. Dazu gehört zum einen, dass sich das UV-Lichtmodul nur einschalten lässt, wenn die Abzugseinrichtung für die Küchenluft in Betrieb ist, und zum anderen dass die Strömung durch das Modulgehäuse über einen dort vorgesehenen Sensor fortlaufend überwacht wird. Ebenso wird das Vorhandensein des Flammschutzfilters über einen Mikroschalter im Modulgehäuse kontrolliert. Die Funktion der einzelnen UV-Strahler wird über deren Stromaufnahme ebenfalls überprüft. Zusätzlich wird über einen Fett-Sensor die Fettverschmutzung der UV-Strahler gemessen. Durch eine Impulsüberwachung wird die Häufigkeit der Reinigungen des UV-Lichtmoduls gezählt, ebenfalls gezählt werden die Betriebsstunden der einzelnen UV-Strahler. Die Steuerung sowie die Software können Module enthalten, die eine Fernüberwachung der Küchenluftreinigungsanlage ermöglichen. Damit können Fehlermeldungen online als SMS oder E-Mail zu der Servicefirma übertragen werden.To ensure safe operation and to detect functional problems of the kitchen air cleaning system at any time and to output appropriate messages, their proper function is monitored via the module housing and the UV light module. For example, an intelligent controller with corresponding software and associated sensors can be used for this purpose. This includes, on the one hand, that the UV light module can only be switched on when the extraction device for the kitchen air is in operation, and, secondly, that the flow through the module housing is continuously monitored by means of a sensor provided there. Likewise, the presence of the flameproof filter is controlled by a microswitch in the module housing. The function of the individual UV lamps is also checked via their power consumption. In addition, the fat contamination of the UV lamps is measured via a fat sensor. By a pulse monitoring, the frequency of cleaning the UV light module is counted, are also counted the operating hours of each UV lamp. The controller as well as the software may contain modules that allow remote monitoring of the kitchen air cleaning system. This allows error messages to be transmitted online as SMS or e-mail to the service company.
