Abstract

Kochfeld (1) mit einer oder mehreren Kochstellen (2) und mit einer oder mehreren Aussparungen (4), wobei zwei oder mehrere Lüfter (38) vorgesehen sind.Hob (1) having one or more cooking zones (2) and having one or more recesses (4), wherein two or more fans (38) are provided.

Description

Die vorliegende Erfindung betrifft ein Kochfeld mit den im Patentanspruch 1 angegebenen Merkmalen.The present invention relates to a hob with the features specified in claim 1.

Aus dem Stand der Technik ist ein Kochfeld bekannt, welches beidseitig und rückseitig neben dem Kochfeld längliche, rechteckige Schlitze aufweist, durch welche die im Bereich des Kochfeldes entstehenden Kochdünste nach unten abgesaugt werden.
Dieses aus dem Stand der Technik bekannte Kochfeld mit beidseitig und rückseitig hiervon vorgesehenen Absaugschlitzen ist insbesondere deswegen nachteilig, weil dort die das Kochfeld tragende Arbeitsplatte - zumindest unmittelbar seitlich von dem Kochfeld - nicht vollständig für Abstellzwecke oder ähnliches nutzbar ist.
Dieses zum Stand der Technik gehörende Kochfeld mit beidseitig und rückseitig hiervon vorgesehenen Absaugschlitzen ist auch deswegen nachteilig, weil sich die beiden seitlichen und die rückwärtige Absaugströmungen - vor allem im besonders bedeutsamen Bereich des Zentrums des Kochfeldes - gegenseitig vollständig oder zumindest teilweise aufheben, so dass dort entstehende Kochdünste keiner effektiven Absaugströmung ausgesetzt sind und sich folglich ungehindert ausbreiten und aufsteigen können.
Ein weiterer Nachteil dieses aus dem Stand der Technik hervorgehenden Kochfeldes mit beidseitig und rückseitig hiervon vorgesehenen Absaugschlitzen besteht darin, dass dort ausgeprägte Herstellungskosten und Materialkosten - insbesondere wegen der Ausbildung der drei Absaugvorrichtungen und dem mit diesen in Verbindung stehenden Abluftkanal-System - anzusetzen sind.
Auch die Wartungskosten-sind bei diesem bekannten Kochfeld besonders hoch, insbesondere da dort drei (!) Fettfilter zu warten sind.
Da bei diesem bekannten Kochfeld mit beidseitig und rückseitig hiervon vorgesehenen Absaugschlitzen - bei Aktivierung der Kochdunstabsaugung - über alle Absaugschlitze gleichzeitig starke Absaugströme freigesetzt werden, ist dort der Energieaufwand für eine Kochdunstabsaugung besonders hoch, weshalb die Effizienz dieses bekannten Kochfeldes auffallend gering ist.
Aufgrund der dort erforderlichen drei starken Absaugströme ist dort auch die Lärmbelastung durch Strömungsgeräusche und Lüftermotoren des Absaug-Systemes ausgeprägt.
Ein weiterer wesentlicher Nachteil des bekannten Kochfeldes mit beidseitig und rückseitig hiervon vorgesehenen Kochdunst-Absaugschlitzen besteht darin, dass dort eine material- und zeitintensive Montage des Kochfeldes an der das Kochfeld tragenden Arbeitsplatte - unter Überbrückung der beidseitigen und rückwärtigen Kochdunst-Absaugschlitze - mittels eines separaten Einbaurahmens erforderlich ist.From the prior art, a cooktop is known, which has on both sides and back next to the hob elongated rectangular slots through which the cooking fumes arising in the region of the hob are sucked down.
This well-known from the prior art hob with both sides and back thereof provided suction slots is particularly disadvantageous because there is the hob carrying countertop - at least immediately laterally from the hob - not completely usable for Abstellzwecke or the like.
This belonging to the prior art cooktop with both sides and back of this provided suction slits is also disadvantageous because the two lateral and the rear Absaugströmungen - especially in the particularly significant area of the center of the hob - cancel each other completely or at least partially, so that there resulting cooking fumes are exposed to any effective suction flow and thus can spread unhindered and ascend.
Another disadvantage of this resulting from the prior art cooktop with both sides and back thereof provided suction slots is that there pronounced manufacturing costs and material costs - especially because of the formation of the three suction devices and related to these exhaust duct system - are to be recognized.
The maintenance costs-are particularly high in this known hob, especially since there are three (!) Grease filter are to be maintained.
Since in this known hob with both sides and back thereof provided suction slots - when activating the cooker extractor - on all suction simultaneously strong suction streams are released, there is the Energy consumption for a Kochdunstabsaugung particularly high, which is why the efficiency of this known hob is strikingly low.
Due to the required there three strong suction currents there is also the noise pollution by flow noise and fan motors of the extraction system pronounced.
Another major disadvantage of the known hob with both sides and back thereof provided cooking vapor extraction slots is that there is a material and time-consuming installation of the hob on the hob supporting countertop - while bridging the two-sided and rear cooker extraction slots - by means of a separate mounting frame is required.

Aufgabe der vorliegenden Erfindung ist daher die Bereitstellung eines Kochfeldes mit einer Einrichtung zum Abzug von Kochdünsten in vertikal unterhalb der Ebene des Kochfeldes liegender Richtung, welches die auf beiden Seiten und rückwärtig von dem Kochfeld befindlichen Flächen auf der das Kochfeld tragenden Arbeitsplatte nicht beansprucht, sondern für Abstellzwecke oder ähnliches nutzbar lässt, welches sowohl im zentralen Bereich des Kochfeldes als auch in dessen Randbereichen ein Aufsteigen und Ausbreiten von Kochdünsten sicher vermeidet, welches besonders niedrige Herstellungs-, Montage-, Wartungs- und Betriebskosten verursacht, welches keinen separaten Einbaurahmen zur Anbringung an die umgebende Arbeitsplatte benötigt, welches in Bezug auf die für die Absaugung eingesetzte elektrische Energie besonders effizient ist und deren Geräuschentwicklung während des Betriebes sehr gering ist.Object of the present invention is therefore to provide a hob with a device for the withdrawal of cooking fumes in vertically below the plane of the hob lying direction, which does not claim the on both sides and back of the hob surfaces on the hob carrying worktop, but for Abstellzwecke or the like can be used, which reliably avoids both rising and spreading of cooking fumes both in the central region of the hob and in its peripheral areas, which causes particularly low manufacturing, assembly, maintenance and operating costs, which does not have a separate mounting frame for attachment to the surrounding worktop is needed, which is particularly efficient in terms of the electrical energy used for the extraction and their noise during operation is very low.

Gemäß den Figuren 3, 5, 6 und 7 kann in jede Aussparung (4) des Kochfeldes (1) ein ein- oder mehrteiliger Fettfilter-Einsatz (6) einsetzbar sein. Dieser Fettfilter-Einsatz (6) ist in der Regel seitlich und/oder unten von einem Abluftkanal (9) umfasst. Vorzugsweise steht der Fettfilter-Einsatz (6) mit dem Randbereich der Aussparung (4) des Kochfeldes (1) dicht in Verbindung.
Der Fettfilter-Einsatz (6) kann beispielsweise im Querschnitt in der Form eines Buchstabens U (siehe Figuren 2, 3, 6 und 7) ausgebildet sein. Alternativ hierzu kann der Fettfilter-Einsatz (6) - zur Vergrößerung der Filterfläche und Reduzierung der Strömungsgeschwindigkeit und damit zur Verbesserung der Wirkung des Fettfilter-Einsatzes (6) - beispielsweise in der Form eines Buchstabens U mit sackförmiger oder mützenförmiger Aufweitung (17) (siehe Figur 5) seines unteren Bereiches zur Seite und/oder in stromabwärtiger Richtung, ausgebildet sein. Im Allgemeinen kann der Fettfilter-Einsatz (6) in seinen Wand-Bereichen Absaug-Öffnungen (7) mit darin integrierten Fettfiltern (8) aufweisen oder-zumindest bereichsweise - in der Art eines gas-permeablen Fettfilters (6) ausgebildet sein.According to the Figures 3 . 5 . 6 and 7 can in each recess (4) of the hob (1) a single or multi-part grease filter insert (6) can be used.

Vorzugsweise sind dann die Drehrichtungen (73) der beiden Lüfterräder (65) dieser beiden Radial-Lüfter (38) zueinander entgegengesetzt: Gemäß Figur 15 kann - in einer Draufsicht - das linke Lüfterrad (65) entgegen dem Uhrzeigersinn rotativ antreibbar sein, während - in einer Draufsicht - das rechte Lüfterrad (65) dann im Uhrzeigersinn rotativ antreibbar ist. In diesem Falle können die beiden Ausblaskammern (67) der beiden Radial-Lüfter (38) zu der zentralen Abluft-Leitung (50) benachbart sein.
Die gegenläufige Ausrichtung der Drehrichtungen (73) gemäß Figur 15 führt zu dem Vorteil, dass die beiden Kochdunst-Ausblasströme (69) den stromabwärts von dem Raum (68) zur Aufteilung und Ausrichtung der Ausblasströme (69) vorgesehenen Geruchsfilter (71) mittelbar über Luftleitflächen (70) oder unmittelbar gleichmäßig anströmen.How special FIG. 15 can be - in a plan view - two radial fan (38) in the fan housing (48) on both sides of the downstream of the central hob recess (4) provided, tubular exhaust air line (50) positioned.

In this case, the two Ausblaskammern (67) of the two radial fan (38) may be adjacent to the central exhaust air line (50).
The opposite orientation of the directions of rotation (73) according to FIG. 15 leads to the advantage that the two Kochdunst Ausblasströme (69) the downstream of the space (68) for dividing and alignment of the Ausblasströme (69) provided odor filter (71) indirectly via air guide surfaces (70) or directly flow uniformly.

Insbesondere Figur 14 zeigt, dass - in einer Draufsicht - der im Inneren des hohlzylindrischen Fettfilters (6) befindliche zentrale Boden-Bereich (74) zumindest gegenüber den beidseitig von diesem zentralen Boden-Bereich (74) vorgesehenen seitlichen Böden (42) der beiden Ansaugkammern (39) unter Ausbildung eines Anschlages (75) für den unteren Randbereich (53) des hohlzylindrischen Fettfilters (6) zumindest etwas abgesenkt sein kann. Ferner kann der zentrale Boden-Bereich (74) - zum Sammeln und Auffangen von übergelaufener Flüssigkeit - zu einer zentralen oder randwärtigen Absenkung (76) geneigt ausgebildet sein. In diesem Falle besteht eine besonders bedienerfreundliche Zugriffsmöglichkeit auf den zentralen Boden-Bereich (74) zu Reinigungszwecken.Especially FIG. 14 shows that - in a plan view - located in the interior of the hollow cylindrical grease filter (6) central floor area (74) at least opposite to both sides of this central floor area (74) provided lateral bottoms (42) of the two suction chambers (39) forming a stop (75) for the lower edge region (53) of the hollow cylindrical grease filter (6) may be at least slightly lowered.

Da die Vorrichtung (5) zum Abzug von Kochdünsten nunmehr im Bereich des geometrischen Flächenschwerpunktes (3) des Kochfeldes (1) zentral vorgesehen ist, wirken auf der gesamten Fläche des Kochfeldes (1) ausreichend starke und sich nicht gegeneinander aufhebende Absaug-Strömungen. Hierdurch werden sowohl im zentralen Bereich des Kochfeldes als auch in dessen Randbereichen ein Aufsteigen und Ausbreiten von Kochdünsten sicher vermieden.
Besondere Vorteile des erfindungsgemäßen Kochfeldes (1) sind ferner darin zu sehen, dass dessen Herstellungs-, Montage-, Wartungs- und Betriebskosten besonders gering sind.
Vorteilhaft im Falle des erfindungsgemäßen Kochfeldes (1) ist außerdem, dass die für die Absaugung eingesetzte elektrische Energie besonders effizient genutzt wird, weshalb der Wirkungsgrad des erfindungsgemäßen Kochfeldes (1) besonders groß ist.
Ein weiterer Vorteil des erfindungsgemäßen Kochfeldes (1) liegt darin, dass die Geräuschentwicklung auch während des Kochdunst-Absaug-Betriebes sehr gering ist.
Bezüglich des erfindungsgemäßen, in Form einer Montageeinheit mit einer Vorrichtung (36) ausgebildeten Kochfeldes (1) kann zusammenfassend festgestellt werden, dass dessen Bauhöhe besonders gering ist, wodurch der im Küchenkorpus ungehindert nutzbare Raum ausgeprägt ist.
Von besonderem Vorteil des erfindungsgemäßen, in Form einer Montageeinheit mit einer Vorrichtung (36) ausgebildeten Kochfeldes (1) ist ferner dessen Kompaktheit und die Tatsache, dass es im Werk vollständig vormontiert werden kann. Dadurch sind der Planungs- und Montageaufwand besonders gering. Schließlich muss die komplett vormontierte, kompakte Montageeinheit nur mehr in eine Aussparung der Arbeitsplatte eingesetzt werden, wodurch sich eine besonders schnelle, einfache und kostengünstige Montage ergibt.Since the device (5) for the extraction of cooking fumes is now provided centrally in the area of the geometric centroid (3) of the hob (1), acting on the entire surface of the hob (1) sufficiently strong and not against each other canceling suction currents. As a result, rising and spreading of cooking fumes are safely avoided both in the central region of the hob and in its peripheral areas.
Particular advantages of the hob according to the invention (1) are also to be seen in the fact that its manufacturing, assembly, maintenance and operating costs are particularly low.
Advantageous in the case of the hob according to the invention (1) is also that the electrical energy used for the extraction is used very efficiently, which is why the efficiency of the hob according to the invention (1) is particularly large.
Another advantage of the hob according to the invention (1) is that the noise is very low even during the cooker-suction operation.
With regard to the hob (1) according to the invention, which is designed in the form of a mounting unit with a device (36), it can be stated in summary that its overall height is particularly low, as a result of which the space usable unhindered in the kitchen cabinet is pronounced.
Of particular advantage of the invention, in the form of a mounting unit with a device (36) formed hob (1) is also its compactness and the fact that it can be completely pre-assembled in the factory. As a result, the planning and assembly costs are particularly low. Finally, the completely pre-assembled, compact mounting unit only needs to be inserted into a recess of the worktop, resulting in a particularly quick, easy and inexpensive installation.

Durch das Vorsehen von zwei oder mehreren, zueinander gegenüberliegenden Radial-Lüftern (38) stromabwärts von dem hohlzylindrischen Fettfilter (6) - gemäß den Figuren 17 und 18 - ergibt sich eine deutlich vergrößerte Wirkfläche des Fettfilters (6) und eine Erhöhung des Durchsatzvolumens unter Verbesserung des Fett-Abscheidegrades sowie unter Ausbildung eines besonders niedrigen Druckverlustes an der größeren, effektiv wirksamen Fettfilterfläche (6). Dies führt zu dem Vorteil, dass die Lüfter-Motoren (56) der Radial-Lüfter (38) besonders klein, energiesparend, energieeffizient und leise ausgebildet sein können. Außerdem kann die Drehzahl der Lüfter-Motoren (56) geringer gewählt werden, weshalb die erfindungsgemäß eingesetzten Radial-Lüfter (38) besonders leise, vibrationsarm und energieeffizient arbeiten.By providing two or more opposing radial fans (38) downstream of the hollow cylindrical grease filter (6) - in accordance with FIGS. 17 and 18 - Resulting in a significantly increased effective area of the grease filter (6) and an increase in the throughput volume to improve the grease separation efficiency and to form a particularly low pressure loss at the larger, effective effective fat filter surface (6). This leads to the advantage that the fan motors (56) of the radial fans (38) can be designed to be particularly small, energy-saving, energy-efficient and silent. In addition, the speed of the fan motors (56) can be selected to be lower, which is why the radial fans (38) used according to the invention operate in a particularly quiet, low-vibration and energy-efficient manner.

Ein besonderer Vorteil des erfindungsgemäßen, in Form einer Montageeinheit mit einer Vorrichtung (36) ausgebildeten Kochfeldes (1) besteht darin, dass sie einen effektiven Schutz vor und Unempfindlichkeit gegenüber übergelaufener, durch die zentrale Aussparung (4) eingedrungene Flüssigkeit - bis zu einem Volumen von 5 l- bietet. Denn durch die Aufhängung der Lüfter-Motoren (56) an dem Boden (45) des Gehäuses (44) für die Beheizungs- oder Kochfeldbeheizung- und Steuerungselektronik steht grundsätzlich das wannenartige Volumen der tiefstliegenden Kochdunst-Ansaugkammer (39) zur Aufnahme von ÜberlaufFlüssigkeit unter Ausschluss einer Gefährdung der Lüfter-Motoren (56) zur Verfügung.A particular advantage of the invention, in the form of a mounting unit with a device (36) formed hob (1) is that it has effective protection against and insensitivity to overflowed, through the central recess (4) penetrated liquid - up to a volume of 5 l- offers. Because by the suspension of the fan motors (56) on the bottom (45) of the housing (44) for the heating or Kochfeldbeheizung- and control electronics is basically the tub-like volume of the lowest cooking fume suction chamber (39) for receiving overflow liquid under exclusion Danger to the fan motors (56) available.
