The deflection member (23) is designed as a tube, single flap or double flap and is preferably adjustable in orientation. It is arranged in the region of the central longitudinal axis of the cooking space (7). The screen (11) has at the top and at the bottom a passage for the return of the air to the blowers. Additionally, a radiator (17, 18) is arranged in each case in the region of the floor (8) and of the roof (9), which radiators can be switched in a programmable manner. This oven takes account of all current practices and wishes. It represents a more far-reaching optimisation for the most practicable satisfaction of all requirements. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Back-, Brat- und Grillofen.The present invention relates to a baking, roasting and grilling oven.

Derartige Oefen sind beispielsweise in der CH-PS 631 802 eingehend erläutert.Such ovens are described in detail in CH-PS 631 802, for example.

Die bekannten Oefen versuchen wohl die immer höheren Ansprüche, insbesondere an den Energieverbrauch und im Hinblick auf den Umweltschutz, zu optimieren. Da­bei wird aber auch noch eine gleichmässige Behandlung des Gargutes verlangt, was zum Teil nur durch den vorgenannten Bedürfnissen widersprechende Massnahmen erreicht werden konnte.The well-known furnaces are trying to optimize the ever higher demands, especially regarding energy consumption and environmental protection. However, even treatment of the food to be cooked is also required, which in some cases could only be achieved by measures contradicting the aforementioned needs.

Die vorliegende Erfindung bezweckt daher, eine all diesen Bedingungen Rechnung tragende, d.h. weiterge­hende Optimierung zu verwirklichen, zu tunlichster Befriedigung aller Ansprüche, allerdings unter Voran­stellung der Behandlung des Gargutes, dem eigentli­chen und grundsätzlichen Zweck derartiger Back-, Brat- und Grillöfen entsprechend.The present invention therefore aims to take account of all of these conditions, i. Realizing further optimization, to the most satisfactory satisfaction of all claims, but with the treatment of the food being cooked in advance, in accordance with the actual and basic purpose of such baking, roasting and grilling ovens.

In diesem Sinne zeichnet sich der erfindungsgemässe Back-, Brat- und Grillofen durch die Massnahme eines der Ansprüche aus.In this sense, the baking, roasting and grilling oven according to the invention is characterized by the measure of one of the claims.

Die Erfindung wird anschliessend beispielsweise an­hand einer Zeichnung erläutert.The invention is subsequently explained, for example, using a drawing.

Es zeigen:

  • Fig. 1 eine schematische Darstellung eines ver­tikalen Längsschnittes durch einen Back-, Brat- und Grillofen, mit einge­zeichneter Luftführung,
  • Fig. 2 eine Innenansicht des Backraumes von vorne gesehen,
  • Fig. 3 eine Ansicht analog Fig. 2, mit weggeho­bener Blende und Einsicht in den Geblä­seraum,
  • Fig. 4 die trennende Blende in Seitenansicht.
Show it:
  • 1 is a schematic representation of a vertical longitudinal section through a baking, roasting and grilling oven, with the air duct shown,
  • 2 an interior view of the baking chamber seen from the front,
  • 3 is a view analogous to FIG. 2, with the cover removed and a view of the blower compartment,
  • Fig. 4 shows the separating screen in side view.

Der in Fig. 1 schematisch dargestellte Längsmittel­schnitt durch einen Backofen 1 zeigt eine Frontwand 2, eine Gehäuserückwand 3 sowie einen Boden 4 und eine Decke 5 des Gehäuses. Ferner ist der Garraum 7 mit dem Garraumboden 8, der Garraumdecke 9 und der einen Garraumseitenwand 10 dargestellt. Der Garraum 7 ist mittels einer Blende 11 von einem Gebläseraum 12 getrennt, dessen Rückwand mit 13 bezeichnet ist. Im Gebläseraum 12 befinden sich ein unteres und ein oberes Umwälzgebläse 14 bzw. 15, welche grundsätz­lich durch ein einziges Gebläse ersetzt werden könn­ten. Durch die Verwendung von zwei - oder mehreren - Gebläsen ist aber der Backofen für die Anpassung an besondere Umstände beweglicher. In diesem Sinne ist es ferner möglich, jedes Gebläse, z.B. durch Aende­rung seiner Drehzahl, dem zugehörenden Backgut anzu­passen. Bei Benützung nur eines Bleches kann der nicht benötigte Umlüfter abgeschaltet und dessen An­saugöffnung in der Blende 11 mittels einer Rückstau­klappe geschlossen werden. Es kann auch eine Umkeh­rung des Drehsinns der Umlüfter zweckmässig sein.The longitudinal central section shown schematically in FIG. 1 through an oven 1 shows a front wall 2, a rear wall 3 and a bottom 4 and a ceiling 5 of the housing. Furthermore, the cooking space 7 with the cooking space floor 8, the cooking space ceiling 9 and the one cooking space side wall 10 is shown. The cooking chamber 7 is separated by a cover 11 from a blower chamber 12, the rear wall of which is designated 13. In the blower chamber 12 there are a lower and an upper circulation blower 14 and 15, which could in principle be replaced by a single blower. By using two - or more - fans, the oven is more flexible for adaptation to special circumstances. In this sense, it is also possible to adapt each fan to the associated baked goods, for example by changing its speed. If only one sheet is used, the can Circulating fans that are not required are switched off and its intake opening in the panel 11 is closed by means of a backflow flap. It may also be appropriate to reverse the direction of rotation of the fan.

Im Garraum 7 sind ferner ein Oberhitze- 17 und ein Unterhitze-Heizkörper 18 vorgesehen.An upper heat 17 and a lower heat radiator 18 are also provided in the cooking chamber 7.

In diesem Backofen 1 ist ferner ein oberes Blech 20 und ein unteres 21 zur Aufnahme des zu behandelnden Gutes dargestellt. Wichtig ist der Umstand, dass diese Bleche 20 und 21 hinten mit der Blende 11 bün­dig abschliessen und ebenso seitlich. Dadurch erge­ben sich oben, unten und seitlich begrenzte Kanäle, dass sich die Luft gezwungenermassen, wie mit den Pfeilen in Fig. 1 dargestellt, in Kanälen bewegt. Es können aber auch mehr als zwei Bleche und eine ent­sprechende Einschiebeschienenzahl am Backofen und zugehörige Heizkörper angeordnet werden, um die Ofenkapazität zu erhöhen. Eine entsprechende Anzahl von Gebläsen erlaubt eine angepasste Luftumwälzung.In this oven 1, an upper plate 20 and a lower 21 for receiving the goods to be treated are also shown. It is important to note that these sheets 20 and 21 are flush with the cover 11 at the back and also on the side. This results in channels which are delimited at the top, bottom and on the side so that the air is forced to move in channels, as shown by the arrows in FIG. 1. However, it is also possible to arrange more than two trays and a corresponding number of insertion rails on the oven and associated radiators in order to increase the oven capacity. An appropriate number of fans allows an adapted air circulation.

Als Folge der grundsätzlichen Asymmetrie der Guts- und zugehörigen Luftströmungsverhältnisse ist die Blende 11 mit einem Luftlenkorgan 23 versehen, wel­ches gestattet, den aus dem Gebläseraum 12 austre­tenden Luftstrahl so zu lenken, dass letztendlich das zu behandelnde Gut in den beiden Blechen 20 und 21 möglichst in gleicher Art und Weise im zeitlich vorgegebenen Rahmen behandelt wird. Dies bedingt im vorstehenden Falle eine Ablenkung des Luftstrahles nach oben, da hier das Gut auf seiner unteren Seite, welche auf dem Blech liegt, die Wärme nicht direkt von der Luft, sondern erst nach der Wärmeleitung durch den Boden des Bleches 20 aufnehmen kann. Dage­gen erfährt der Boden des unteren Bleches 21 den Einfluss des unter ihm liegenden Unterhitze-Heizkör­pers 18 direkt. Flankierend dazu kann die program­mierbare Ober- und/oder Unterhitze, je nach Backgut, das auch unterschiedlich sein kann, zur Anwendung gebracht werden.As a result of the basic asymmetry of the material and associated air flow conditions, the diaphragm 11 is provided with an air steering element 23, which allows the air jet emerging from the blower chamber 12 to be directed in such a way that ultimately the material to be treated in the two plates 20 and 21 is as possible as possible is treated in the same way in a timely manner. In the above case, this causes the air jet to be deflected upwards, since here the material on its lower side, which lies on the sheet metal, does not directly apply the heat from the air, but only after heat conduction through the bottom of the sheet 20. In contrast, the bottom of the lower plate 21 directly experiences the influence of the lower heat radiator 18 located below it. To accompany this, the programmable top and / or bottom heat can be used, depending on the baked goods, which can also be different.

Es ist dabei möglich, die Lage dieser Luftlenkorgane 23 zu verstellen, wobei dieses Organ entweder aus Klappen oder aus einem Rohr bestehen kann. Die Ein­stellung kann entweder permanent oder von aussen mittels eines Betätigungsgestänges, gegebenenfalls in Funktion von Gutstemperaturen, reguliert werden.It is possible to adjust the position of these air directing members 23, which member can either consist of flaps or a tube. The setting can be regulated either permanently or from outside using an actuating linkage, possibly in function of good temperatures.

Wie aus Fig. 2 ersichtlich, ist die Blende 11 an ih­ren Rändern 24 an der Rückwand 15 befestigt, so dass sich ein achteckiger Gebläseraumquerschnitt bildet. Dessen Schrägseiten sind mit 25 bezeichnet.As can be seen from FIG. 2, the panel 11 is fastened at its edges 24 to the rear wall 15, so that an octagonal blower chamber cross section is formed. Its sloping sides are designated by 25.

Aus Fig. 3 ist die Anordnung der beiden als Propel­lergebläse ausgebildeten Umwälzgebläse 14 und 15 er­sichtlich, welche selbstredend durch eine andere Ge­bläsebauart, wie Radialgebläse, Querstromgebläse, Axiallüfter o. dgl. ersetzbar sind.3 shows the arrangement of the two circulating fans 14 and 15 designed as propeller fans, which of course can be replaced by another fan type, such as radial fans, cross-flow fans, axial fans or the like.

Beim beschriebenen Umluft-, Brat-, Back- und Grill­ofen kann es sich um einen Ofen mit sog. pyrolyti­schem Reinigungssystem handeln, wobei dieser Ofen weitgehend automatisiert ist. Bei dieser Konstruk­tion wird grundsätzlich das Prinzip hochgehalten, die Speisen im ganzen Ofenraum bzw. Garraum gleich­ zeitig auf gleiche Temperaturen zu bringen und damit einer möglichst gleichen homogenen Behandlung zu un­terziehen. Dies kann auf zwei oder mehr Ebenen er­folgen, wobei, wie geschildert, das asymmetrische Anbringen des Gutes im Garraum dazu zwingt, mit an­deren asymmetrischen Komponenten, z.B. Stereoreg­lern, tunlichst Symmetrie bezüglich des zu behan­delnden Gutes zu erreichen.The circulating air, roasting, baking and grilling oven described can be an oven with a so-called pyrolytic cleaning system, this oven being largely automated. In this construction, the principle is basically upheld, the food in the entire oven space or cooking space is the same to bring them to the same temperatures in good time and to subject them to the same homogeneous treatment as possible This can be done on two or more levels, whereby, as described, the asymmetrical placement of the food in the cooking space forces other symmetrical components, for example stereo controls, to achieve symmetry with the goods to be treated, if possible.

Im Sinne der vorliegenden Erfindung ist erkannt wor­den, dass die Kombination des Anbringens der Wärme­quelle im Bereich des Gargutes einerseits und deren einstellbarem Bestreichen durch im Umwälzsystem ge­förderte Luft andererseits die besagte Gutsasymme­trie zu egalisieren vermag. Durch diese Kombination der direkten Strahlungswärme von den Heizelementen einerseits und der turbulenten temperaturausglei­chenden Luftbewegung andererseits sowie durch die Möglichkeit der Regulierung der einzelnen Komponen­ten bezüglich Temperatur, Energie, Umwälzgeschwin­digkeit, Umwälzrichtung der bewegten Luft u. dgl. wird eine Anpassung in optimierendem Sinne möglich.In the sense of the present invention, it has been recognized that the combination of attaching the heat source in the region of the food to be cooked on the one hand, and its adjustable brushing by air conveyed in the circulation system, on the other hand, can equalize the said goods asymmetry. This combination of the direct radiant heat from the heating elements on the one hand and the turbulent temperature-compensating air movement on the other hand and by the possibility of regulating the individual components with regard to temperature, energy, circulation speed, circulation direction of the moving air and the like. Like. An adjustment in an optimizing sense is possible.

Dadurch ergibt sich sogar die Möglichkeit, unglei­ches Gargut gleichzeitig im gleichen Backofen zu­friedenstellend zu behandeln.This even makes it possible to treat dissimilar items satisfactorily in the same oven at the same time.

Alle in der Beschreibung und/oder den Figuren darge­stellten Einzelteile und Einzelmerkmale sowie deren Permutationen, Kombinationen und Variationen sind erfinderisch, und zwar für n Einzelteile und Einzel­merkmale mit den Werten n = 1 bis n → ∞.All the individual parts and individual features shown in the description and / or the figures, as well as their permutations, combinations and variations, are inventive, namely for n individual parts and individual features with the values n = 1 to n → ∞.
