Description

Die Erfindung betrifft einen Mikrowellenofen, insbesondere für eine Verkaufsvorrichtung für erwärmte Lebensmittel, mit einem Garraum, der eine Wandung mit Bestückungsöffnung aufweist, sowie mit einer Erzeugungsvorrichtung für Mikrowellen.The invention relates to a microwave oven, in particular for a heated food vending apparatus, having a cooking chamber which has a wall with a loading opening, and a microwave generating device.

Entsprechende Verkaufsvorrichtungen sind beispielsweise bekannt aus der US-5,147,068 oder der WO 2004/075125 . Bei diesen bekannten Vorrichtungen sind jeweils von außen zugängliche Mikrowellenöfen vorgesehen. In deren Garräume werden durch Schwenktüren hindurch, die als Bestückungsöffnungen dienen, von der Verkaufsvorrichtung ausgegebene Fertiggerichte manuell eingesetzt und dann erhitzt. Nachteilig hieran ist, dass die Handhabung für Gerichte relativ aufwändig ist und auf jeden Fall durch den Benutzer der Verkaufsvorrichtung manuell durchzuführen ist.Corresponding sales devices are known, for example from the US 5,147,068 or the WO 2004/075125 , In these known devices, in each case externally accessible microwave ovens are provided. In their cooking chambers are prepared by swing doors, which serve as mounting openings, issued by the vending machine ready meals used manually and then heated. The disadvantage of this is that the handling of dishes is relatively complex and is in any case carried out manually by the user of the vending machine.

Eine erste Aufgabe der vorliegenden Erfindung ist es somit, eine Vorrichtung anzugeben, mit der Lebensmittel vor ihrer automatischen Ausgabe bereits erwärmt werden, ohne dass hierzu manuell eingegriffen werden muss.A first object of the present invention is therefore to specify a device with which food is already heated before it is automatically dispensed without having to intervene manually.

Ein besonderer Bedarf diesbezüglich besteht dabei für entsprechende Verkaufsvorrichtungen, die z.B. neben einem bekannten Verkaufsautomaten für Heißgetränke wie Kaffee, Espresso etc. angeordnet werden sollen, um ein zusätzliches Angebot wie ein erwärmtes Croissant, ein erwärmtes Brioche o.ä. anzubieten, die insbesondere in mediterranen Ländern gerne zu einem Heißgetränk wie erwähnt hinzugenommen werden. Entsprechende Verkaufsvorrichtungen müssen insbesondere schmal bauen, da der Aufstellungsraum für Heißgetränke-Verkaufsautomaten in Kantinen, Teeküchen, Büros etc. oft nur sehr beschränkt ist. Für entsprechende Verkaufsvorrichtungen werden Breiten von ca. 25 cm und weniger angestrebt. Hieraus ergeben sich zusätzliche Anforderungen im Hinblick auf das Bauvolumen, das für einen Mikrowellenofen zur Verfügung steht.There is a particular need for such vending devices, e.g. In addition to a known vending machine for hot drinks such as coffee, espresso, etc. are to be arranged to an additional offer such as a heated croissant, a heated Brioche o.ä. to be added to, especially in Mediterranean countries like a hot beverage as mentioned. Corresponding sales devices must be particularly narrow, since the space for hot drinks vending machines in canteens, tea kitchens, offices, etc. is often very limited. For appropriate sales devices widths of about 25 cm and less are desired. This results in additional requirements in terms of the volume of construction, which is available for a microwave oven.

Eine weitere Aufgabe der vorliegenden Erfindung ist es somit, auch diese Randbedingungen zu berücksichtigen.A further object of the present invention is therefore also to take into account these boundary conditions.

Die oben genannten Aufgaben werden erfindungsgemäß dadurch gelöst, dass bei dem erfindungsgemäßen Mikrowellenofen mindestens die Wandung des Garraumes verschwenkbar ist, so dass die Mikrowellen der Erzeugungsvorrichtung durch die Bestückungsöffnung des Garraumes zu leiten sind.The abovementioned objects are achieved according to the invention in that in the microwave oven according to the invention at least the wall of the cooking chamber is pivotable, so that the microwaves of the generating device are to be guided by the loading opening of the cooking chamber.

Diese konstruktiven Details der Erfindung haben den Vorteil, dass der Mikrowellenofen sehr kompakt gebaut werden kann, insbesondere muss kein Raum vorgesehen sein, um eine Tür zu öffnen, wie sie bei bisher bekannten Mikrowellenöfen vor der Bestückungsöffnung üblich ist. Des weiteren ist eine Verschwenkung der Wandung zum Schließen des Mikrowellenofens auch automatisiert möglich, so dass ein manuelles Eingreifen eines Benutzers überflüssig wird.These structural details of the invention have the advantage that the microwave oven can be made very compact, in particular, no space must be provided to open a door, as is common in previously known microwave ovens before the placement opening. Furthermore, a pivoting of the wall to close the microwave oven is also automated, so that a manual intervention of a user is unnecessary.

Ein weiterer Vorteil liegt auch darin, dass der Garraum keine wie sonst üblichen Öffnungen haben muss, um die Mikrowellen eintreten zu lassen. Er ist somit einfacher zu fertigen.Another advantage lies in the fact that the cooking chamber does not have to have openings as usual to allow the microwaves to enter. He is thus easier to manufacture.

Unter Fertigungsgesichtpunkten ist es dabei insbesondere auch vorteilhaft den Garraum als Ganzes zu verschwenken. Hierdurch entfallen ansonsten eventuell auftretende Dichtprobleme, die an den Bewegungsfugen auftreten könnten, die bei lediglich bewegter Wandung und feststehenden Boden und Decke auftreten könnten.Under manufacturing aspects, it is particularly advantageous to pivot the oven as a whole. This eliminates otherwise possibly occurring sealing problems that could occur at the movement joints, which could occur with only moving wall and fixed floor and ceiling.

Bei einer bevorzugten Ausführungsform ist die Erzeugungsvorrichtung für die Mikrowelle, üblicherweise ein Magnetron, mit einen Kanal gekoppelt, vor dessen Ausgang die Bestückungsöffnung des Garraumes verschwenkbar ist.In a preferred embodiment, the generating device for the microwave, usually a magnetron, is coupled to a channel in front of the outlet of which the loading opening of the cooking chamber can be pivoted.

Durch die Verwendung eines Kanals ist man bei der Positionierung der Mikrowellenerzeugungsvorrichtung freier. Außerdem kann die Magneterzeugungsvorrichtung so in einem geschützteren Bereich untergebracht werden und ist somit vor mechanischen Beschädigungen leichter zu schützen.By using a channel one is freer in positioning the microwave generating device. In addition, the magnetic generating device can be accommodated in a more protected area and thus is easier to protect against mechanical damage.

In diesem Zusammenhang wird auch vorgeschlagen, den Garraum in der Stellung mit seiner Bestückungsöffnung vor dem Kanalausgang translatorisch auf diesen zuzubewegen.In this context, it is also proposed to move the cooking chamber in the position with its loading opening in front of the channel exit translationally on this.

Dies ist insbesondere von Vorteil, wenn der Kanalausgang in einer Schließplatte angeordnet ist und zwischen dem um die Bestückungsöffnung des Garraumes umlaufenden Rand und dieser Schließplatte eine mikrowellendichte Dichtung angeordnet ist. Eine derartige Dichtung ist aufgrund der translatorischen Bewegung nicht in ungünstiger Weise scherend belastet.This is particularly advantageous if the channel exit is arranged in a closing plate and a microwave-tight seal is arranged between the edge surrounding the loading opening of the cooking chamber and this closing plate. Such a seal is not burdened by shearing due to the translational movement in an unfavorable manner.

Ansonsten ist diese Dichtung vorteilhaft, um ein unerwünschtes Austreten von Mikrowellenstrahlung zu verhindern.Otherwise, this seal is advantageous to prevent unwanted leakage of microwave radiation.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist der Garraum aus einer nach oben offenen Stellung um eine Horizontalachse schwenkbar in die Stellung, in der dann die Bestückungsöffnung vor dem Kanalausgang liegt. Diese letztere Position ist dann im Wesentlichen in einer Horizontalrichtung ausgerichtet.In a particularly preferred embodiment of the invention, the cooking chamber is pivotable from an upwardly open position about a horizontal axis in the position in which then the loading opening in front of the channel exit. This latter position is then aligned substantially in a horizontal direction.

Bei dieser Konstruktion ist das Zuführen eines zu erwärmenden Lebensmittel in den Garraum relativ einfach: Es kann von oben durch die Bestückungsöffnung in den Garraum aus einer darüberliegenden Speichereinheit hineinfallen. Der Garraum schwenkt dann mit dem Produkt befüllt in die Stellung vor dem Kanalausgang der Mikrowellenerzeugungsvorrichtung, so dass die aus diesem austretenden Mikrowellen das Produkt erwärmen.In this construction, the feeding of a food to be heated in the cooking chamber is relatively simple: It can fall from above through the loading opening in the oven from an overlying storage unit. The cooking chamber then pivots with the product filled in the position in front of the channel output of the microwave generating device, so that the microwaves emerging from this heat the product.

Danach schwenkt der Garraum vorteilhafterweise mit seiner Bestückungsöffnung in eine nach unten offene Stellung weiter, so dass das erwärmte Produkt aus dem Garraum herausrutscht oder herausfällt und aus einer darunter entsprechend angeordneten Auffangschale o.ä. entnommen werden kann.Thereafter, the cooking chamber pivots advantageously with its loading opening in a downwardly open position, so that the heated product slips out of the oven or falls out and from a correspondingly arranged below collecting tray. can be removed.

Es ist dann möglich, dass der Garraum mit seiner Bestückungsöffnung in die nach oben offene Stellung zurückschwenkt also insgesamt nur um etwa 180° verschwenkbar ist. Vorzugsweise wird aber vorgeschlagen, die beim Schwenken durchgeführte Rotationsbewegung zu vervollständigen und den Garraum somit lediglich in eine Dreh- bzw. Rotationsrichtung zu bewegen. Der Garraum wird dabei also insgesamt jeweils um 360° rotiert. Hierdurch ist Spiel innerhalb des Antriebs für die Schwenk- oder Rotationsbewegung für den Garraum zu vermeiden.It is then possible that the cooking chamber pivots back with its loading opening in the upwardly open position so that is only pivotable about 180 ° in total. Preferably, however, it is proposed to complete the rotation movement performed during pivoting and thus to move the cooking chamber only in a direction of rotation or rotation. The oven is thus rotated in total 360 °. As a result, play within the drive for the pan or rotary motion for the cooking chamber is to be avoided.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels. Dabei zeigt.

Figur 1
eine Verkaufsvorrichtung mit erfindungsgemäßem Mikrowellenofen in der Schnittansicht;
Figur 2
einen erfindungsgemäßen Mikrowellenofen mit verschiedenen Stellungen des Garraumes.
Further advantages and features of the invention will become apparent from the following description of an embodiment. It shows.
FIG. 1
a sales device with inventive microwave oven in the sectional view;
FIG. 2
a microwave oven according to the invention with different positions of the cooking chamber.

In Figur 1 erkennt man eine Schnittansicht durch eine Verkaufsvorrichtung 1. Diese weist in ihrem oberen Bereich einen Speicherraum 2 auf, in den Lebensmittel wie Croissants, Brioches etc. in Päckchen 3 haltbar verpackt auf mehreren Ebenen eingelagert sind.In FIG. 1 can be seen a sectional view through a vending device 1. This has in its upper part a storage space 2, in the food as Croissants, brioches, etc. packed in small packages 3 are stored on several levels.

Diese Päckchen stehen dabei in den Lücken von in Horizontalrichtung ausgerichteten schraubengangförmigen Wendeln 4. Für die Entnahme eines entsprechenden Päckchens wird eine solche Wendel durch eine nicht dargestellte Steuerung für eine Umdrehung durch einen ebenfalls nicht dargestellten Antrieb motorisch betätigt, wodurch ein entsprechendes Päckchen am vorderen Ende der Wendel über eine Kante 5 geschoben wird und dann nach unten fällt. Am Ende des Fallens wird das Päckchen dann durch ein Leitblech 6 zu einem verschwenkbaren Garraum 7 geführt. Dieser ist in der Figur 1 mit nach oben gerichteter Bestückungsöffnung 8 dargestellt.These packets are in the gaps of aligned in the horizontal direction helical spirals 4. For the removal of a corresponding packet such a helix is motorized by a control, not shown for one revolution by a likewise not shown drive, whereby a corresponding packet at the front end of Spiral is pushed over an edge 5 and then falls down. At the end of falling the packet is then passed through a guide plate 6 to a pivotable cooking chamber 7. This one is in the FIG. 1 with upwardly directed insertion opening 8 shown.

In dem Garraum 8 wird das Päckchen mit dem darin enthaltenen Lebensmittel erwärmt, wie dies weiter unten anhand der Figur 2 erläutert wird, und wird abschließend nach unten in eine Auffangschale 9 ausgegeben, aus der es durch eine Klappe 10 zu entnehmen ist.In the cooking chamber 8, the packet is heated with the food contained therein, as described below with reference to FIG. 2 is explained, and is finally issued down into a drip tray 9, from which it can be seen through a flap 10.

Anhand der Figur 2 wird nun der Erwärmungsvorgang eines Päckchens 3 innerhalb des Garraumes 7 schrittweise erläutert. Zu Beginn fällt ein Päckchen 3 von oben in den Garraum 7, dessen Bestückungsöffnung 8 dabei nach oben gerichtet ist.Based on FIG. 2 Now, the heating process of a packet 3 is explained step by step within the cooking chamber 7. At the beginning of a packet 3 falls from above into the cooking chamber 7, the loading opening 8 is directed upward.

An den Seiten ist der Garraum 7 mit Lagerstutzen 10 verbunden, deren Mittelachse sich in Horizontalrichtung erstreckt. Mit diesen Lagerstutzen ist der Garraum 7 über Gleitsteine 11 in einer Traverse 12 beweglich gelagert. Die Traverse 12 läuft dabei in etwa horizontal seitlich an einem ebenfalls horizontal liegenden Kanal 13 entlang, in den von einem Magnetron als Mikrowellenerzeugungsvorrichtung 14 Mikrowellen abgegeben werden. Das Magnetron 14 erhält seine Energie dabei über einen Transformator 15 sowie entsprechende Steuerungs- und andere elektronische Bauelemente 16.On the sides of the cooking chamber 7 is connected to bearing neck 10, whose central axis extends in the horizontal direction. With these sockets, the cooking chamber 7 is movably mounted on sliding blocks 11 in a traverse 12. The traverse 12 runs approximately horizontally along the side of an also horizontally lying channel 13 along, are emitted into the microwaves from a magnetron 14 as a microwave generating device. The magnetron 14 receives its energy via a transformer 15 and corresponding control and other electronic components 16th

Nachdem das Päckchen mit dem darin enthaltenen Lebensmittel in dem Garraum 7 aufgenommen wurde, verschwenkt der Garraum wie in der Figur 2B dargestellt mit seiner Bestückungsöffnung in Richtung auf den Ausgang 17 des Kanals 13, wobei dann die Bestückungsöffnung im Wesentlichen zur Seite geschwenkt ist. In dieser Stellung wird der Garraum 17 dann durch einen Elektroantrieb 18 über eine Verschiebung der Gleitsteine 11 entlang der Traverse 12 translatorisch bewegt, wobei eine Dichtung 19, die um die Bestückungsöffnung 8 an dem Garraum 7 umläuft in eine korrespondierende Aufnahme an einer Schließklappe 20 eingeführt und dichtend zur Anlage gebracht wird, wie dies in der Figur 2C dargestellt ist.After the packet was received with the food contained in the cooking chamber 7, the cooking chamber pivots as in the FIG. 2B shown with its loading opening in the direction of the outlet 17 of the channel 13, in which case the loading opening is pivoted substantially to the side. In this position, the cooking chamber 17 is then moved translationally by an electric drive 18 via a displacement of the sliding blocks 11 along the traverse 12, wherein a seal 19 which surrounds the loading opening 8 on the cooking chamber 7 in a corresponding receptacle on a closing flap 20 is inserted and brought into sealing contact, as shown in the Figure 2C is shown.

Innerhalb der Schließklappe 20 ist der Ausgang 17 des Kanals 13, in den durch das Magnetron 14 die Mikrowellen eingespeist werden. Diese treten jetzt durch den Ausgang 17 in der Schließklappe 20 und durch die Bestückungsöffnung 8 in den Garraum 7 hinein und erwärmen dort das darin befindliche Päckchen mit einem Lebensmittel.Within the closing flap 20 is the output 17 of the channel 13, in which the microwave is fed by the magnetron 14. These now pass through the outlet 17 in the closing flap 20 and through the loading opening 8 into the cooking chamber 7 and heat there the package located therein with a food.

Am Ende dieses Erwärmungsvorganges werden über den Elektroantrieb 18 die Gleitsteine 11 wieder in Horizontalrichtung translatorisch zurückbewegt, wodurch die Dichtung 19 wieder von der Schließplatte 20 getrennt wird wenn der Garraum 7 geöffnet wird, bevor dann wie in der Figur 2D dargestellt der Garraum 7 weiter geschwenkt wird, bis seine Bestückungsöffnung 8 nach unten gerichtet ist und damit das Päckchen 3 aus dem Inneren des Garraumes 7 nach unten herausrutscht. Der Garraum 7 wird dann weiter rotiert, bis er wieder die Position erreicht, die in der Figur 2A dargestellt ist. Alternativ ist es auch möglich, den Garraum 7 zurückzuschwenken, wobei dann lediglich der Schließvorgang ausgelassen wird, der in der Figur 2C dargestellt ist.At the end of this heating process, the sliding blocks 11 are again moved back translationally in the horizontal direction via the electric drive 18, whereby the seal 19 is again separated from the closing plate 20 when the cooking chamber 7 is opened before then as in the FIG. 2D shown the cooking chamber 7 is further pivoted until its loading opening 8 is directed downward and thus the packet 3 from the interior of the cooking chamber 7 slips down. The cooking chamber 7 is then rotated further until it reaches the position again in the FIG. 2A is shown. Alternatively, it is also possible to zurückzuschwenken the cooking chamber 7, in which case only the closing operation is omitted, in the Figure 2C is shown.

Die hier beschriebene Vorrichtung ist besonders kompakt und ermöglicht es, ein Produkt wie ein Brioche, ein Croissant o.ä. zu erwärmen, wobei die Breite, insbesondere auch des Verkaufsautomaten 1 sehr gering bleiben kann, beispielsweise im Bereich von weniger als 25 cm.The device described here is particularly compact and allows a product such as a brioche, a croissant or similar. to heat, wherein the width, in particular of the vending machine 1 can remain very low, for example in the range of less than 25 cm.

Es soll dabei aber auch erwähnt werden, dass ein entsprechender Mikrowellenofen natürlich auch in einem breiteren Verkaufsautomaten einsetzbar ist, bei dem dann ggf. auch mehrere Speicherplätze mit schraubengangförmigen Wendeln 4 nebeneinander angeordnet sind. Bei einem solchen breiteren Verkaufsautomaten wäre dann das Leitblech 6 ggf. auch trichterförmig ausgebildet, um von seitlich oberhalb herunterfallende Produkte zu der nach oben gerichteten Bestückungsöffnung 8 zu leiten.It should also be mentioned, however, that a corresponding microwave oven can of course also be used in a wider vending machine, in which then, if necessary, several memory locations with helical spirals 4 are arranged side by side. In such a broader vending machine then the baffle 6 would possibly also funnel-shaped, in order to guide from above falling above products to the upwardly directed loading opening 8.

Es kann auch dabei im übrigen vorgesehen werden, dass auf besonderen Wunsch eines Kunden ein Päckchen 3 nicht erwärmt wird. Hierfür kann am Automaten eine Taste vorgesehen sein, deren Drücken durch die Steuerung berücksichtigt wird, die die oben beschriebenen Vorgänge innerhalb des Verkaufsautomaten steuert.It can also be provided, moreover, that at the special request of a customer, a packet 3 is not heated. For this purpose, a key can be provided on the machine, the pressure of which is taken into account by the controller which controls the above-described operations within the vending machine.
