[0001] Predlagani izum se nanaša na kuhinjsko napo, obsegajočo zbiralni odsek, v katerega je vstavljena filtrima naprava, pri čemer slednja obsega filtrimi panel iz filtrimega materiala, razporejenega v nosilnem okviru, in pri čemer napa dalje obsega niz zasukljivih lamel, povezanih z omenjenim nosilnim okvirom, tako da vsaj deloma prekrivajo omenjeni panel iz filtrimega materiala.[0001] The present invention relates to a kitchen hood comprising a collection section into which the device filters are inserted, the latter comprising filter panels of a filter material disposed in the support frame, and wherein the hood further comprises a plurality of pivotable lamellas associated with said support frames so that at least partially overlap the said panel of the filter material.

[0002] Kuhinjska napa uvodoma navedene vrste je znana iz patenta št. EP 2 966 363 BI in obsega zbiralni odsek, v katerega je vstavljena filtrima naprava, ki ima v nosilnem okvira razporejen filtrimi panel iz filtrimega materiala, sesalni vod z vstopom, razporejenim nad panelom iz filtrimega materiala, odstranjevalnik plinov, razporejen v omenjenem vodu, pri čemer je vstopna odprtina omenjenega odstranjevalnika plinov obrnjena le k prvemu odseku omenjenega panela iz filtrimega materiala, in pri čemer je drugi odsek panela iz filtrimega materiala dosegljiv s sesanjem omenjenega odstranjevalnika plinov preko kanalske razporeditve. Znana kuhinjska napa dalje obsega niz lamel, ki imajo vnaprej določeno smer poteka in so povezane z omenjenim nosilnim okvirom ter prekrivajo omenjeni prvi odsek filtrimega panela, pri čemer je vsakokratna lamela iz niza lamel, kot posledica sesanja, ki ga ustvari omenjeni odstranjevalnik plinov, glede na omenjeni nosilni okvir prosto zasukljiva okoli svoje osi Υ-Υ med položajem, v katerem je v bistvu vzporedna s površino prvega odseka filtrimega panela, ki je obrnjen k vstopni odprtini odstranjevalnika plinov, tako da je nagnjeni položaj lamel funkcija obsega odsesavanja.[0002] A cooking hood of the above-mentioned type is known from Patent no. EP 2 966 363 BI and comprises a collecting section into which the filters are inserted a device which, in the carrier frame, is arranged with a filter panel panel of a filter material, an intake duct with an inlet arranged above a panel of a filter material, a gas discharger arranged in said duct; wherein the inlet opening of said gas removal device is directed only to the first section of said panel from the filter material, and wherein the second section of the panel from the filter material is accessible by suction of said gas detector via channel arrangement. The known cooking hood further comprises a series of lamellas having a predetermined direction of flow and associated with said support frame and overlapping said first section of the filter panel, wherein the respective lamellas from the series of lamellas as a result of the suction generated by said gas detector, on said support frame is freely rotatable about its Y-Y axis, in a position in which it is essentially parallel to the surface of the first section of the filter panel facing the inlet of the gas discharger so that the inclined position of the lamella is a function of the amount of suction.

[0003] Ker pa omenjene lamele v celoti prekrivajo omenjeni prvi odsek filtrimega panela, ni zagotovljenega enakomernega pretoka odsesovanega zraka po vseh površinah filtrimega panela. Zlasti se je omenjena pomanjkljivost pokazala v primera, ko pogonski motor odstranjevalnika plinov deluje z različnim številom vrtljajev.[0003] However, since said lamellas completely overlap the said first section of the filter panel, there is not provided a steady flow of the extracted air across all surfaces of the filter panel. In particular, said disadvantage has been shown in the case where the propulsion engine of the gas detector operates at different speeds.

[0004] Naloga izuma je ustvariti filtrimo napravo pri kuhinjski napi, s katero se zagotovi karseda enakomerno odsesovanje zraka preko vseh površin filtrimega panela.[0004] It is an object of the invention to provide a filtering device for a kitchen nap, which ensures as much as possible even air extraction over all surfaces of the filter panel.

[0005] Zastavljena naloga je po predlaganem izumu rešena z značilnostmi, podanimi v značilnostnem delu 1. patentnega zahtevka.

[0006] Izum je v nadaljevanju podrobneje predstavljen na osnovi neomejujočega izvedbenega primera in s sklicevanjem na priložene skice, kjer kaže sl. 1 kuhinjsko napo v delnem prerezu v navpični ravnini in tridimenzionalnem pogledu; sl. 2 filtrimo napravo v pogledu v smeri puščice II s sl. 1; sl. 3 usmerjevalno napravo v tridimenzionalnem predstavitvenem pogledu; sl. 4 usmerjevalno napravo v pogledu od zgoraj; sl. 5 usmerjevalno napravo v delnem pogledu v smeri puščice V s sl. 3.[0006] The invention is further described below in more detail on the basis of the non-limiting embodiment and by referring to the accompanying drawings, wherein FIG. 1 kitchen hood in a partial cross-section in a vertical plane and three-dimensional view; Fig. 2, filter the device in the view in the direction of the arrow II in FIG. 1; Fig. 3 routing device in a three-dimensional representation view; Fig. 4 directional device in the top view; Fig. 5 is a directional device in a partial view in the direction of the arrow V in FIG. 3.

[0007] Kuhinjska napa 1 obsega sesalni kanal 2, ki praviloma poteka v navpični smeri, in zbiralni odsek 3, ki je priključen spodnjemu koncu sesalnega kanala 2. Zbiralni odsek 3 obsega na strani, obrnjeni proč od povezave s sesalnim kanalom 2, vsaj eno filtrimo napravo 4.[0007] The cooking hood 1 comprises a suction channel 2 which generally runs in a vertical direction and a collection section 3 which is connected to the lower end of the suction channel 2. The collecting section 3 comprises on the side facing away from the connection with the suction channel 2 at least one Filter the device 4.

[0008] Omenjena vsaj ena filtrima naprava 4 obsega nosilni okvir 5, v katerega je vstavljen oz. kateri vsebuje ploskovno intenziven filtrimi panel 6, ki prekriva celotno notranje območje nosilnega okvira 5. Omenjeni filtrimi panel 6 lahko vsebuje vsaj en kovinski mrežasti element in/ali element iz aktivnega oglja in/ali poliuretanski mrežasti element. Dalje je proti sesalnemu kanalu 2 obrnjena stran filtrime naprave 4 opremljena z vsaj eno usmerjevalno napravo 7, ki je s pomočjo niza lamel 7’, katerih vsaka je zasukljiva okoli svoje vzdolžne osi, zasnovana na način žaluzije.[0008] Said at least one filter device 4 comprises a support frame 5 into which it is inserted and / which comprises a panel-intensive panel panel 6 covering the whole inner region of the carrier frame 5. Said panel panels 6 may contain at least one metal mesh element and / or an activated carbon element and / or a polyurethane mesh element. Further, against the suction channel 2, the side of the filter device 4 is provided with at least one routing device 7 which, by means of a series of lamellae 7 ', each of which is rotatable around its longitudinal axis, is based on the manner of the louver.

[0009] Napa 1 dalje obsega sesalno sredstvo 8 s pogonskim motorjem, ki je razporejeno v sesalnem kanalu 2 in v območju nad zbiralnim odsekom 3. Omenjeno sesalno sredstvo 8, ki je primeroma razporejeno v neposredni soseščini usmerjevalne naprave 7 in približno središčno nad slednjo, transportira odsesane pline in maščobe skozi vod 9, ki je na po sebi znan način razporejen v sesalnem kanalu 2.[0009] The hood 1 further comprises a suction means 8 with a drive motor arranged in the suction channel 2 and in the area above the collection section 3. Said suction means 8, which is, for example, arranged in the direct neighborhood of the routing device 7 and approximately centrally above the latter, transports the exhaust gases and fats through the conduit 9, which is in a known manner arranged in the suction channel 2.

[0010] Po predlaganem izumu je predvideno, da so izmere omenjene usmerjevalne naprave 7, gledano ploskovno, manjše od izmer filtrime naprave 4. Po prednostnem izvedbenem primeru je predvideno, da je med vsaj enim odsekom oboda nosilnega okvira 5 filtrime naprave 4 in vsaj enim odsekom oboda usmerjevalne naprave 7 predviden odmik 10, ki predstavlja prosto površino filtrimega panela 6, to je površino, ki ni pokrita z usmerjevalno napravo 7. Pri prednostnem izvedbenem primeru je odmik 10 oz. je omenjena površina filtrimega panela 6, ki ni pokrita z usmerjevalno napravo 7, predvidena vzdolž vsaj dela zunanjega oboda oz. vzdolž vsaj ene zunanje stranice zbiralnega odseka 3. Po še bolj prednostnem izvedbenem primeru je predvideno, da je odmik 10 oz. je omenjena površina filtrimega panela 6, ki ni pokrita z usmerjevalno napravo 7, predvidena vzdolž obeh zunanjih bočnih stranic kot tudi vzdolž sprednje stranice, obrnjene k uporabniku, zbiralnega odseka 3. Po predlaganem izumu je tudi mogoče, da je odmik 10 oz. je omenjena površina filtrimega panela 6, ki ni pokrita z usmerjevalno napravo 7, predvidena vzdolž celotnega zunanjega oboda zbiralnega odseka 3.[0010] According to the present invention it is envisaged that the dimensions of said routing device 7, viewed flat, are smaller than the dimensions of the filter of the device 4. According to a preferred embodiment, it is provided that between the at least one portion of the periphery of the carrier frame 5 the filters of the device 4 and at least one a circumferential section 10 of the periphery of the routing device 7 is provided, which is the free surface of the filter panel 6, that is, the surface not covered by the routing device 7. In the preferred embodiment, the deviation is 10 oz. said surface of the filter panel 6, which is not covered by the routing device 7, is provided along at least a portion of the outer circumference, along at least one outer side of the collection section 3. According to an even more preferred embodiment, the deviation is 10 oz. said surface of the filter panel 6 which is not covered by the routing device 7 is provided along both of the outer lateral sides as well as along the front face facing the user of the collection section 3. According to the invention, it is also possible that the deviation of 10 oz. said surface of the filter panel 6 which is not covered by the routing device 7 is provided along the entire outer circumference of the collection section 3.

[0011] Vse navedeno seveda velja tedaj, ko je kuhinjska napa 1 oz. je zbiralni odsek 3 le-te ploskovno gledano zasnovan kot mnogokotnik, običajno kot pravokomik. Če pa je kuhinjska napa 1 oz. je zbiralni odsek 3 le-te ploskovno gledano zasnovan drugače, na primer kot krog, elipsa ali podobno, je povsem očitno, da je odmik 10 oz. je omenjena površina filtrimega panela 6, ki ni pokrita z usmerjevalno napravo 7, predvidena po vsaj delu ustreznega oboda zbiralnega odseka 3.[0011] All of the above applies, of course, when the cooking hood is 1 oz. the collection section 3 of the latter is flatly viewed as a polygon, usually as a rectangle. However, if the cooking hood is 1 oz. the collecting section 3 of it is shaped differently from a planar view, for example, as a circle, an ellipse or the like, it is quite obvious that the deviation is 10 oz. said surface of the filter panel 6 which is not covered by the routing device 7 is provided by at least a portion of the corresponding circumference of the collection section 3.

[0012] Omenjena usmerjevalna naprava 7 obsega nosilni okvir 11, ki je s pomočjo prvega niza vodilnih štrlin 12 držan in v prvi smeri Y premakljiv v omenjenem nosilnem okviru 5 filtrime naprave 4.

In each case, the opposite side is configured with suitable guides for receiving said first set of projections 12.

[0013] V omenjenem nosilnem okviru 11 usmerjevalne naprave 7 je dalje razporejeno usmerjevalno ogrodje 13, ki je držano in v drugi smeri X premakljivo v omenjenem nosilnem okvirju 11 usmerjevalne naprave 7. Omenjena druga smer X poteka pri tem približno pravokotno na omenjeno prvo smer Y. Po predlaganem izumu je predvideno, da ležita omenjeni smeri X, Y v vodoravni ravnini oz. v ravnini filtrimega panela 6. Omenjeno držanje in/ali premikanje usmerjevalnega ogrodja 13 je doseženo s pomočjo drugega niza vodilnih štrlin 14, ki so lahko zasnovane bodisi na nosilnem okvirju 11 usmerjevalne naprave 7 ali na omenjenem usmerjevalnem ogrodju 13.

The said second direction X proceeds approximately perpendicular to said first direction Y According to the present invention, the said directions X, Y in the horizontal plane and / in the plane of the filter panel 6. The said holding and / or movement of the routing frame 13 is achieved by means of a second set of guide projections 14 which can be designed either on the carrier frame 11 of the routing device 7 or on the said routing frame 13. In each case, shaped with suitable guides for receiving said second set of projections 14.

[0014] Po predlaganem izumu je predvideno, da je ena od izmer usmerjevalnega ogrodja 13, prednostno izmera v omenjeni drugi smeri X, manjša od izmere nosilnega okvirja 11 usmerjevalne naprave 7, s čimer je omogočeno premikanje usmerjevalnega ogrodja 13 v ustrezni omenjeni smeri znotraj omenjenega nosilnega okvirja 11 in posledično nastanek omenjenega odmika 10.[0014] According to the present invention it is envisaged that one of the dimensions of the guide frame 13, preferably measured in said second direction X, is smaller than the dimensions of the carrier frame 11 of the routing device 7, so that it is possible to move the routing frame 13 in the corresponding said direction within said the supporting frame 11 and, consequently, the emergence of said distance 10.

[0015] Dalje je po predlaganem izumu predvideno, da je ena od izmer nosilnega okvirja 11 usmerjevalne naprave 7, prednostno izmera v omenjeni smeri Y, manjša od izmere nosilnega ogrodja 5 filtrime naprave 4, s čimer je omogočeno premikanje nosilnega okvirja 11 v ustrezni omenjeni smeri znotraj omenjenega nosilnega ogrodja 5 in posledično nastanek omenjenega odmika 10.[0015] Furthermore, according to the present invention, it is envisaged that one of the dimensions of the support frame 11 of the routing device 7, preferably measured in said direction Y, is smaller than the dimensions of the support frame 5 of the filter device 4, so that the supporting frame 11 can be moved in the corresponding said direction within the said support frame 5 and, consequently, the emergence of said distance 10.

[0016] Omenjeno usmerjevalno ogrodje 13 je zasnovano iz paroma medsebojno vzporednih stranic 13’; 13”, pri čemer je prvi par medsebojno vzporednih strani 13’ predviden za drsno sodelovanje z omenjenim drugim nizom štrlin 14 nosilnega okvirja 11. Vsakokratna stranica 13” iz drugega para medsebojno vzporednih stranic 13” je v smislu žaginega lista zasnovana z nizom približno trikotnih zob 15, katerih prosta boka 16 oz. 17 sta postavljena pod kotom a oz. β glede na splošni vodoravni potek filtrime naprave 4. Vsakokratni zob 15 prve stranice iz para medsebojno vzporednih stranic 13” je v območju svojega prvega boka 16 s pomočjo usmerjevalne stene 18 povezan z območjem prvega boka 16 nasproti ležečega zoba 15 druge stranice iz para medsebojno vzporednih stranic 13”. Omenjena usmerjevalna stena 18 prednostno zavzema enak nagib oz. kot a glede na splošni vodoravni potek filtrime naprave 4, kot omenjeni prosti bok 16 zoba 15.[0016] Said routing frame 13 is formed from a pair of mutually parallel sides 13 '; 13 ", wherein the first pair of mutually parallel sides 13 'is provided for sliding engagement with said second array of projections 14 of the support frame 11. Each page 13' from the second pair of mutually parallel sides 13 'is, in the sense of a saw blade, designed with a series of approximately triangular teeth 15, whose free side is 16 oz. 17 are placed at an angle a and / β with respect to the general horizontal flow of the device filters 4. Each tooth 15 of the first side of the pair of mutually parallel sides 13 ' is in the region of its first side 16 by means of the guide wall 18 connected to the region of the first flank 16 of the opposite tooth 15 of the second side of the pair of each other parallel pages 13 ". Said guiding wall 18 preferably occupies the same inclination or inclination. as with respect to the general horizontal flow of the filters of the device 4 as said free side 16 of the tooth 15.

[0017] Med vsakokratnim zobom 15 prve stranice iz para medsebojno vzporednih stranic 13” in vsakokratnim nasproti ležečim zobom 15 druge stranice iz para medsebojno vzporednih stranic 13” je razporejena omenjena lamela 7’, ki je na po sebi znan način zasukljivo razporejena v območju vsakokratnega zoba 15. Po predlaganem izumu je predvideno, da lamela 7’ nalega na omenjeni drugi bok 17 vsakokratnega zoba 15, s čimer omenjena lamela prednostno zavzema enak nagib oz. kot β glede na splošni vodoravni potek filtrime naprave 4, kot omenjeni prosti bok 17 zoba 15.[0017] Between the respective teeth 15 of the first side of the pair of mutually parallel sides 13 ' and the respective opposite tooth 15 of the second side of the pair of mutually parallel sides 13 ' the said lamella 7 ' is arranged which is in a known known way rotatably arranged in the region of the respective According to the present invention, the lamella 7 'is placed on said second flank 17 of each tooth 15, whereby said lamella preferably occupies the same slope, as β with respect to the general horizontal flow of the filters of the device 4, as said free side 17 of the tooth 15.

[0018] Omenjena lamela 7’ prednostno obsega ugoden aerodinamičen prečni presek, s čimer se pozitivno vpliva na tok zraka skozi lamele. Dalje je po predlaganem izumu predvideno, da lamele 7’ obsegajo enak ali medsebojno različen prečni presek. Omenjene lamele 7’ lahko po svojem vzdolžnem poteku obsegajo enak ali spremenljiv prečni presek. Še dalje je predvideno, da lamele 7’ obsegajo enako ali medsebojno različno maso, kar se doseže na primer s pomočjo uporabe različnih materialov za posamezno lamelo 7’, vnosom ene ali več votlin v posamezno lamelo 7’ in podobnega.[0018] The said lamellae 7 'preferably comprise a favorable aerodynamic cross-section, thereby positively influencing the flow of air through the blades. Further, according to the present invention, the lamellae 7 'encompass the same or mutually different cross-section. Said blades 7 'may, according to their longitudinal course, comprise an identical or variable cross-section. It is further provided that the lamellae 7 'comprise the same or different mass, which is achieved by, for example, the use of different materials for a single lamella 7', the introduction of one or more cavities into a single lamella 7 'and the like.
