Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung für einen mit einer Ofentür versehenen Erhitzungsofen - insbesondere für einen Backofen, in dessen Ofenraum sich bei Erhitzungsvorgängen, wie beispielsweise Bratvorgängen, heiße Luft, insbesondere Wrasen, bildet - für den eine Absaugung der heißen Luft mittels einer Absaugeinrichtung mit Absaugöffnung vorgesehen ist.The invention relates to a device for a heating oven provided with an oven door - in particular for an oven, in the oven space of which during heating processes, such as roasting, hot air, especially vapors, forms - for which a suction of hot air by means of a suction device with suction opening is provided.
Aus der EP 0 290 925 A3 ist es bekannt, aus einem Back- oder Bratofen die sich beim Erhitzen bildende Heißluft permanent nach hinten abzusaugen. Weiterhin ist es aus der DE 83 08 713.3 U bekannt, die Heißluft oder den Wrasen nach oben abzuführen. Die Heißluft oder der Wrasen strömen in diesem Fall oberhalb der Ofentür nach vorn ab. Wegen der relativ hohen Temperaturen dieser Dämpfe ist das Bedienungspersonal beim Bedienen der Ofentür oder der Bedienungsknöpfe für den Ofen und die Herdplatten deutlich gefährdet.It is known from EP 0 290 925 A3, from a baking or Roast the hot air that forms when heated vacuum to the rear. Furthermore, it is from DE 83 08 713.3 U known to discharge the hot air or vapors upwards. The hot air or the vapors flow in this Fall forward above the oven door. Because of the relative high temperatures of these vapors is the operator when operating the oven door or the control buttons for the Oven and the hot plates are clearly at risk.
Obige Lösungen beschränken sich auf das konstante Ableiten von Wrasen während des Betriebes, gewährleisten jedoch nicht ausreichend das Austreten eines Schwalles heißer Dämpfe beim Öffnen der Ofentür, wenn in dem Ofen bereits bratendes Gut behandelt wird.The above solutions are limited to constant derivation of vapors during operation, but do not guarantee sufficient the escape of a gush of hot vapors Open the oven door if there is already food in the oven is treated.
Es ist Aufgabe der Erfindung, eine Vorrichtung der eingangs erwähnten Art zu schaffen, bei der das Austreten des Schwalles heißer Luft oder heißer Dämpfe beim Öffnen der Ofentür bei Bedarf unterbunden oder weitmöglichst verringert wird.It is an object of the invention, a device of the beginning to create the kind mentioned in which the discharge of the gush hot air or hot vapors when opening the oven door if necessary prevented or reduced as far as possible.
Die gestellte Aufgabe ist erfindungsgemäß dadurch gelöst, durch eine Vorrichtung für einen mit einer Ofentür versehenen Erhitzungsofen - etwa einen Backofen, der auch als Heißluftofen ausgebildet sein kann - in dessen Ofeninnenraum sich bei Erhitzungsvorgängen heiße Luft, insbesondere Wrasen, bildet, der eine Absaugung mittels einer oder mehrerer Absaugöffnungen und einer Absaugeinrichtung aufweist, wobei
- die Absaugöffnungen auch bei geschlossener Ofentür innerhalb des Erhitzungsofens im Ofeninnenraum angeordnet sind,
- die Absaugeinrichtung mittels eines Schalters zumindest teilweise vor dem Öffnen der Ofentür oder sogar ausschließlich vor dem Öffnen der Ofentür in Betrieb setzbar ist oder durch den Schalter die Absaugwirkung einer ständig im Betrieb befindlichen Absaugvorrichtung verstärkt wird und
- beim Öffnen der Ofentür, bei dem sich ein Türöffnungsspalt ausbildet, die Absaugeinrichtung so ausgelegt ist, daß durch das zumindest teilweise vor dem Öffnen der Ofentür bewirkte Absaugen das Austreten heißer Luft bzw. Wrasens aus dem Türöffnungsspalt vermindert wird.
- the suction openings are arranged inside the heating furnace even when the furnace door is closed,
- the suction device can be put into operation by means of a switch at least partially before the furnace door is opened or even exclusively before the furnace door is opened or the suction effect of a suction device which is constantly in operation is increased and
- when the oven door is opened, in which a door opening gap is formed, the suction device is designed such that the suction of hot air or fumes from the door opening gap is reduced by the suctioning effected at least partially before the opening of the oven door.
Jede Bedienungsperson kennt das Phänomen, daß die heiße Luft in das Gesicht steigt, z.B. die Brille beschlägt; man weicht unweigerlich vor dem heißen Schwall zurück. Ein gezieltes Absaugen vor und ggf. auch im Augenblick des Türöffnens verhindert diese lästigen Vorgänge oder macht sie wenigstens erträglicher. Es kommt noch hinzu, daß die Wrasen in der Küche nach oben steigen und die Wände, insbesondere die Küchendecke, nachhaltig verschmutzen. Dieser Nachteil fällt beim Einsatz der erfindungsgemäßen Vorrichtung weg oder wird wenigstens gemildert.Every operator knows the phenomenon that the hot air rising into the face, e.g. the glasses fog up; you give way inevitably back from the hot surge. A targeted one Suction before and if necessary also prevented at the moment of opening the door these annoying processes or at least do them more bearable. Add to that the vapors in the kitchen climb up and the walls, especially the kitchen ceiling, pollute sustainably. This disadvantage drops when using the device according to the invention away or will at least mitigated.
Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, daß ein oder mehrere Absaugöffnungen in der Nähe des Türöffnungsspaltes in den Ofenraum münden. According to a preferred embodiment of the invention, that one or more suction openings nearby of the door opening gap open into the furnace chamber.
Die Absaugvorrichtung kann zusätzlich auch als bei zumindest teilweise geöffneter Tür wirksame Türluftabsaugung ausgebildet sein, wobei die Türluftabsaugeinrichtung so ausgelegt und die Absaugöffnungen so im Erhitzungsofen angeordnet sind, daß die heiße Luft im Erhitzungsofen beim Öffnen der Ofentür, bei dem sich ein Öffnungsspalt bildet, durch die Türluftabsaugung vom Öffnungsspalt so weit wie möglich ferngehalten wird, um nicht aus dem Öffnungsspalt auszutreten.The suction device can also be used as at least partially opened door trained effective air extraction be, the door air suction device designed so and so arranged the suction openings in the heating furnace are that the hot air in the heating furnace when opening the Oven door with an opening gap through which Keep air extraction from the opening gap as far as possible in order not to emerge from the opening gap.
Der Schalter kann nicht nur als Ein- und/oder Ausschalter der Absaugeinrichtung bzw. in Bezug auf die Drosselklappen wirken, sondern auch so ausgebildet sein, daß er die Absaugwirkung auch hinsichtlich der Intensität variiert. Die erfindungsgemäße Absaugeinrichtung wird durch den Schalter gesteuert und ausschließlich vor dem Öffnen der Ofentür mit einer kurzeitig die heiße Luft / den Wrasen aus dem Offeninneraum entfernenden Absaugintensität betrieben. Der Schalter befindet sich vorzugsweise an der Vorderfront des Erhitzungsofens und wird weiterhin vorzugsweise von der Bedienungsperson manuell geschaltet.The switch can not only be used as an on and / or off switch the suction device or in relation to the throttle valves act, but also be designed so that it has the suction effect also varies in intensity. The invention Suction device is controlled by the switch and only before opening the oven door one briefly the hot air / vapors from the open interior removing suction intensity operated. The desk is preferably located on the front of the heating oven and continues to be preferred by the operator switched manually.
Vorzugsweise ist der Schalter weiterhin an eine Logik gekoppelt, die ein zeitlich verzögertes Deaktivieren der Absaugvorrichtung bzw. ein Schließen der Drosselklappen oder auch nur eine Verringerung der Absaugwirkung auslöst. Die Logik kann lediglich in einer Verzögerung des Deaktivierens um eine konstante Zeit bestehen, in der nämlich ein ausreichendes Absaugen des Wrasens bzw. der heißen Luft gewährleistet ist, um ein Öffnen der Ofentür ohne Belästigung durch ausströmende Ofeninnenluft zu erlauben oder aber auch an einen Temperaturfühler und das Unterschreiten eines Temperaturgrenzwertes gekoppelt sein.The switch is preferably also coupled to a logic, a delayed deactivation of the suction device or a closing of the throttle valves or also only triggers a reduction in the suction effect. The logic can only result in a delay of deactivation by one constant time, in which there is sufficient Suction of the vapors or the hot air is guaranteed, to open the oven door without being disturbed by escaping To allow furnace air or to a temperature sensor and falling below a temperature limit be coupled.
Weiterhin ist es möglich, daß Zeit- und/oder Temperatur gesteuert zunächst ein Absaugen der Ofeninnenluft bewirkt wird und nachfolgend ggf. unter verminderter Saugleistung und gekoppelt an das Öffnen der Tür eine Türluftabsaugung zusätzlich aktiviert wird. Weiterhin kann der Bedienungsperson nach Aktivieren der Absaugeinrichtung ebenfalls Zeit- und/oder Temperatur gesteuert angezeigt werden, wann die Ofentür zu öffnen ist.It is also possible for the time and / or temperature to be controlled suction of the furnace interior air is initially effected and subsequently possibly with reduced suction power and coupled at the opening of the door an additional door air extraction is activated. Furthermore, the operator can after activating the suction device also time and / or temperature controlled when the oven door can be opened.
Die Türluftabsaugvorrichtung kann eine Regeleinrichtung aufweisen, mit der beim Öffnen der Ofentür die Türluftabsaugung ein- /zugeschaltet wird oder in der Absaugwirkung veränderbar ist, wobei der Türluftabsaugung durch einen beim Öffnen der Ofentür zusätzlich schaltenden Türluftabsaugschalter geschaltet wird oder durch zeitverzögertes Schalten des Schalters der Absaugeinrichtung bewirkt werden.The door air suction device can have a control device, with the door air extraction when opening the oven door is switched on / on or the suction effect can be changed is, the door air extraction by a when opening the door air extraction switch that switches the oven door or by delayed switching of the switch the suction device can be effected.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß ein oder mehrere Absaugöffnungen der Türluftabsaugeinrichtung in der Nähe des Türöffnungsspaltes in den Ofenraum münden. Damit läßt sich die heiße Luft im Bereich der sich beim Öffnen bildenden Öffnung verbessert erfassen.According to a further embodiment of the invention, that one or more suction openings of the door air suction device near the door opening gap in the furnace room flow out. This allows the hot air in the area of better register themselves when opening.
Weiterhin kann durch Schließen der Ofentür ggf. ein Steuerimpuls ausgelöst werden, der die Absaugvorrichtung einschließlich der Türluftabsaugung deaktiviert oder auf den Normalbetrieb zurückregelt.Furthermore, a control pulse may be triggered by closing the furnace door triggered, including the suction device the door air extraction deactivated or on the Regulates normal operation.
Soweit eine während des Ofenbetriebs ständig im Betrieb befindliche Absaugvorrichtung vorhanden ist, kann die Heißluft von der Ofentür weg in die Absaugluft der Absaugvorrichtung eingeleitet werden, indem im Türluftabsaugluftrohr zwischen den Absaugöffnungen am Öffnungsspalt des Ofenraumes und der Einmündung dieses Rohres in das Rohr der Absaugvorrichtung eine Vorrichtung, wie eine Drosselklappe , vorgesehen ist, die das Türluftabsaugluftrohr durch Wirkung des Schalters und/oder durch Öffnen der Ofentür ganz oder teilweise freigibt, wobei im Türluftabsaugluftrohr eine zusätzliche Türluftabsaugvorrichtung vorgesehen sein kann. Die zusätzliche vordere Türluftabsaugung ist vorzugsweise nur beim Öffnen der Ofentür zusätzlich aktiv.As far as one that is constantly in operation during furnace operation Suction device is available, the hot air away from the oven door into the suction air of the suction device can be initiated by between in the door air exhaust air pipe the suction openings at the opening gap of the furnace chamber and the Mouth of this pipe in the pipe of the suction device a device such as a throttle valve is provided, the the door air exhaust pipe by the action of the switch and / or fully or partially releases by opening the oven door, an additional door air suction device in the door air suction air pipe can be provided. The additional Front door air extraction is preferably only when opening the oven door is also active.
Die Saugwirkung der Türluftabsaugung kann z.B. durch eine Drosselklappe einstellbar sein. Weiterhin können in der Ofentür an Absaugkanäle angeschlossene Absaugöffnungen vorgesehen sein, über die heiße Luft aus dem Öffnungsspalt wegsaugbar ist. Durch obige Maßnahmen kann am Öffnungsbereich des Ofenraumes ein Luftvorhang gebildet werden, der das Austreten der heißen Luft aus dem Ofenraum möglichst weitgehend unterbindet. Die Türluftabsaugung wird vorzugsweise erst beim Öffnen oder kurz vor dem Öffnen wirksam.The suction effect of the door air extraction can e.g. by a Throttle valve can be adjustable. Furthermore, in the Furnace door provided on suction channels connected to suction channels be sucked out of the opening gap via the hot air is. The above measures can be taken at the opening area an air curtain is formed in the furnace chamber, which prevents leakage the hot air from the furnace space as much as possible prevents. The door air extraction is preferably only first effective when opening or shortly before opening.
Es muß natürlich sichergestellt sein, daß empfindliches Backgut nicht durch die schlagartig einsetzende Absaugung beschädigt wird. So kann Kuchen, wenn er eine plötzliche Abkühlung durch die verstärkt einsetzende Absaugung erfährt, zusammenfallen. Nach einer weiteren Ausgestaltung der Erfindung ist deshalb vorgesehen, daß die Absaugwirkung an einer Regeleinheit, z.B. einem Regelschalter, einstellbar ist. Die Wirkung der Absaugeinrichtung einschließlich der Türluftabsaugeinrichtung kann dabei manuell oder elektronisch gesteuert variiert und ggf. bis auf Null zurückgestellt werden.It must of course be ensured that sensitive Baked goods not due to the sudden onset of suction is damaged. So can cake if it has a sudden cooling experienced by the increasing suction, collapse. According to a further embodiment of the invention is therefore provided that the suction effect on a Control unit, e.g. a control switch, is adjustable. The Effect of the suction device including the door air suction device can be controlled manually or electronically varied and, if necessary, reset to zero.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Stellung der Drosselklappe(n) mittels des Türluftabsaugschalters einstellbar ist.According to a further embodiment of the invention, that the position of the throttle valve (s) by means of the door air extraction switch is adjustable.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß im Öffnungsbereich des Ofenraumes, d.h. auf der der Öffnung zugewandten Seite, ein flächiger Luftvorhang ausgebildet wird, der das Austreten der heißen Luft aus dem Ofenraum möglichst weitgehend unterbindet. According to a further embodiment of the invention, that in the opening area of the furnace space, i.e. on the the Side facing the opening, a flat air curtain is formed the hot air escaping from the furnace chamber prevented as far as possible.
Wenn kein Leerrohr für das Abführen der heißen Dämpfe nach Außen oder in den ggf. über dem Herd befindlichen Wrasenabzug oder eine Filtervorrichtung zur Verfügung steht, dann bringt die Hitze der abgesaugten Luft und deren Verschmutzung, beispielsweise durch Fett, Probleme mit sich.If no empty pipe for the removal of hot vapors after Outside or in the fume hood possibly located above the stove or a filter device is available, then brings the heat of the extracted air and its pollution, for example due to fat, problems with itself.
Nach einer weiteren Ausgestaltung der Erfindung ist deshalb vorgesehen, daß die heiße Luft aus dem Backofen vor dem Ableiten aus dem Erhitzungsofen zunächst in einem Filter gereinigt und danach ggf. zusätzlich in einem Kühler abgekühlt wird. Der Filter kann beispielsweise ein Edelstahlfilter sein. Als Kühler kann ein Flüssigkeitsbad, insbesondere ein Wasserbad, dienen. Filter und der Kühler lassen sich vorteilhaft unterhalb des Backofens anordnen.According to a further embodiment of the invention provided that the hot air from the oven before draining first cleaned in a filter from the heating furnace and then optionally cooled in a cooler becomes. The filter can be a stainless steel filter, for example his. A liquid bath, in particular a Water bath, serve. Filters and the cooler can be advantageous Arrange below the oven.

Die Ofentür läßt sich dann nur öffnen, wenn eine wirkungsvolle Absaugung durch die Öffnung (9) und ggf. die Türabsaugung über die Rohrleitung (12) zusätzlich aktiviert wurde. Dafür kann eine mechanische Sperre vorgesehen sein, die für wenige Sekunden das Türöffnen blockiert. Beide Wrasenabzüge (5) und (5a) wirken in der dargestellten Ausführungsform im Augenblick des Türöffnens gemeinsam als Türluftabsaugeinrichtungen und werden für diesen Zweck auch gemeinsam in der Absaugleistung so eingeregelt, daß an allen Absaugöffnungen der Ausführungsbeispiele genügend Absaugleistung zur Verfügung steht, um den Wrasen oder die Heißluft am Öffnungsspalt (14a) gar nicht oder möglichst wenig austreten zu lassen. Durch den Schalter (18) wird im Regelfall höchste Absaugleistung eingestellt. Um beim Backen von empfindlichen Gütern, wie Kuchen, diese nicht zu schädigen, ist vorgesehen, die Leistung des Wrasenabzuges (5), bzw. beider Wrasenabzüge (5) und (5a) für den Zeitraum des Ofentüröffnens nach Wunsch einzustellen. Hierzu ist der Schalter (18) als regelbar vorgesehen, mit dem die Absaugleistung von Hand bis auf Null zurückgestellt werden kann.One belonging to the kitchen stove serving as a suction device Vapor extractor (5) has an extractor fan, not shown on the hot air, the vapors, through the exhaust air pipe (11) sucks. That is why the suction is in operation the suction device by pressing the switch (18) to the rear furnace area (13), in Heating operation of the exhaust air pipe (12) by means of a Throttle valve (16) closed, which is only when the The oven door (8) opens. The opening of the throttle valve (16) is used a switch (17). In the exhaust air pipe (12) is still another fume hood acting as a fume hood (5a), which can be switched on together with the throttle valve (16) is. To the effect of the suction at the moment of opening To improve the oven door (8), a time advance can be set become. Even the suction power at this moment increase. The oven door can then only be opened if effective suction through the opening (9) and if necessary, additionally extract the door via the pipe (12) was activated. A mechanical lock can be provided for this that blocks the door opening for a few seconds. Both vapors (5) and (5a) act in the shown Embodiment at the moment of opening the door together as Door air suction devices and are used for this purpose too adjusted in the suction power so that at all Suction openings of the exemplary embodiments have sufficient suction power is available to the vapors or the hot air at the opening gap (14a) not at all or as little as possible to let out. The switch (18) is usually highest suction power set. To when baking sensitive goods, such as cakes, not to damage them, the output of the vapor extraction (5) or both vapor vents (5) and (5a) for the period of the oven door opening adjust as desired. This is the switch (18) is provided as controllable, with which the suction power of Hand can be reset to zero.
Es sind hier diverse Betriebsvarianten möglich. Als Beispiele seien genannt:Various operating options are possible here. As examples are mentioned:
Der Wrasenabzug (5) ist unter geringerer Saugleistung ständig im Betrieb, wobei das eigentlich impulsartige Absaugen des Wrasens aus dem Offeninnenraum durch Aktivieren des Schalters (18) vor dem Öffenen der Ofentür (8) bewirkt wird und die vordere Absaugung mit dem Wrasenabzug (5a) nur beim Öffnen der Ofentür in Betrieb gesetzt wird.The fume hood (5) is constantly under lower suction power in operation, which is actually pulsed suction the vapor from the open interior by activating the Switch (18) before opening the oven door (8) is effected and the front suction with the vapor extraction (5a) only at Opening the oven door is put into operation.
Der Wrasenabzug (5a) fällt weg und das Absaugen des Wrasens wird nach Aktivieren des Schalters (18) einzig durch den Wrasenabzug (5) bewirkt.The fume hood (5a) is omitted and the fume suction is only activated by the switch (18) Fume extraction (5) causes.
Fig. 3 zeigt die Absaugwirkung im vorderen Bereich (14) des Backofens (6). Man erkennt, daß der sich oberhalb eines Bratgutes (19), beispielsweise einer Gans, bildende Wrasen beim Öffnen der Ofentür (8) aus dem sich dabei bildenden Öffnungsspalt (14a) in die Abzugsrohre (11) und (12) gesaugt wird und so nicht nach außen austritt. Die Bewegung der Wrasenströme ist mit den Pfeilen (20) und (29) angegeben.Fig. 3 shows the suction effect in the front area (14) of the Oven (6). One recognizes that the one above Roasted food (19), for example a goose, forming vapors when opening the oven door (8) from the resulting Opening gap (14a) sucked into the exhaust pipes (11) and (12) and does not leak outwards. The movement of the vapors is indicated by the arrows (20) and (29).
Fig. 4 und 5 zeigen die Wirkungsweise von Varianten, die die Wirkung der Absaugung weiter verbessern. In der Ofentür (8) sind ein oder mehrere Absaugkanäle (21) vorgesehen, die an Absaugöffnungen (23) auslaufen, die zum Ofenraum (7) offen sind. Man erkennt anhand der Bewegungspfeile (24), wie die heiße Luft aus dem Öffnungsspalt (14a) weggerissen wird: Eine weitere Verbesserung bringt es, wenn noch weitere Absaugöffnungen (25) und (26) vorgesehen werden, die an den oder die Absaugkanäle (21) angeschlossen sind.4 and 5 show the operation of variants that the Further improve the suction effect. In the oven door (8) one or more suction channels (21) are provided which are connected to Suction openings (23) run out, which open to the furnace chamber (7) are. You can see from the movement arrows (24) how the hot air is torn out of the opening gap (14a): one it brings further improvement if there are more suction openings (25) and (26) can be provided to the or the suction channels (21) are connected.
Es ist auch denkbar und in Fig. 5 gezeigt, einen Luftvorhang (27) zu bilden. Die Luft würde dann im vorderen oberen Bereich (14) beispielsweise aus Düsen (28) nach unten strömen. Der Wrasen wird nach hinten geführt in Richtung der Pfeile (29). Durch Absaugöffnungen (30) wird die Luft des Luftvorhanges (27) durch den Verbindungskanal (31) zum Wrasenabzug (5) geleitet. Die Strömungsrichtung des Luftvorhanges (27) kann natürlich auch umgekehrt von unten nach oben verlaufen.An air curtain is also conceivable and shown in FIG. 5 (27) to form. The air would then be in the front upper area (14) flow down from nozzles (28), for example. The vapor is directed backwards in the direction of the arrows (29). The air of the air curtain is removed through suction openings (30) (27) through the connecting channel (31) to the vapor extraction (5) headed. The flow direction of the air curtain (27) can of course also run the other way round from bottom to top.
In Fig. 6 ist eine Aufbereitung des Wrasens für den Fall dargestellt, in dem der Wrasen nicht heiß und möglichst wenig schmutzführend abgeführt werden soll. Im Öffnungsbereich (14) des Backofens (6), nahe dem Öffnungsspalt (14a), wird beim Öffnen der Ofentür (8) die heiße, durch die Pfeile (20) angedeutete Luft durch die Absaugöffnungen (10) in das Absaugluftrohr (12) eingesaugt. Eine Absaugeinrichtung (5a verstärkt die Saugwirkung. Zuvor wurde ein weiterer Teil der heißen Luft durch die Absaugöffnung (9) und ein Saugrohr (33) nach unten abgesaugt, wo in das Saugrohr (33) das Absaugluftrohr (12) mündet. Die heiße Luft strömt im Saugrohr (33) vereint schließlich in einen Filter (34). Der Filter (34) kann ein Edelstahlfilter und der Kühler (35) ein Wasserbad sein. Vorzugsweise sind der Filter (34) und der Kühler (3) unterhalb des Erhitzungsofens (6) angeordnet.In Fig. 6 is a preparation of the fumigation for the case shown in which the vapors are not hot and as little as possible to be carried away in a dirt-carrying manner. In the opening area (14) of the oven (6), near the opening gap (14a) when opening the oven door (8) the hot arrow (20) indicated air through the suction openings (10) into the suction air pipe (12) sucked in. A suction device (5a increases the suction effect. Previously, another part of the hot air through the suction opening (9) and a suction pipe (33) sucked down, where in the suction pipe (33) the suction air pipe (12) opens. The hot air flows in the intake manifold (33) finally united in a filter (34). The filter (34) a stainless steel filter and the cooler (35) a water bath his. Preferably, the filter (34) and the cooler (3) arranged below the heating furnace (6).
Unterhalb dieses Filters (34) befindet sich ein Wasserbecken (35), in das die im Filter (34) gereinigte Luft einfließt und sich abkühlt. Der Wrasenabzug (5) saugt die nun gereinigte und abgekühlte Luft in das Abzugsrohr (4), welches unmittelbar nach außen oder in den Wrasenabzug (2) für die Küchendünste führt.A water basin is located below this filter (34) (35) into which the air cleaned in the filter (34) flows and cools off. The vapor extractor (5) sucks the cleaned one and cooled air in the exhaust pipe (4), which immediately to the outside or into the fume hood (2) for the kitchen vapors leads.
Der Filter (34) und das als Kühler (35) dienende Wasserbecken sind als eine Behandlungseinheit (36) zusammengefaßt, die hinter einer Klappe (37) angeordnet ist.The filter (34) and the water basin serving as a cooler (35) are combined as a treatment unit (36), which is arranged behind a flap (37).
