Description

Die Erfindung betrifft einen Ofen, insbesondere Bratofen oder Backofen, mit einer Vorrichtung zum Erfassen der Temperatur im Innern eines Bratguts, Backguts oder dergleichen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a furnace, in particular roasting oven or oven, with a device for detecting the temperature in the interior of a roasting product, dough or the like according to the preamble of claim 1.

Bei bekannten Bratöfen und Backöfen besteht die Möglichkeit, die Temperatur des Bratguts bzw. Backguts mittels eines separaten Sensors zu bestimmen. Dazu umfasst der Sensor ein langgestrecktes Teil, das in das Bratgut bzw. Backgut eindringbar ist. Der bekannte Sensor ist über ein Kabel mit einem Stecker verbunden, der in einer Buchse lösbar befestigbar ist. Üblicherweise befindet sich die Buchse in einer Seitenwand des zu beheizenden Raums des Bratofens.In the case of known roasting ovens and ovens, it is possible to determine the temperature of the roasting product or baking product by means of a separate sensor. For this purpose, the sensor comprises an elongated part, which can be penetrated into the fried food or dough. The known sensor is connected via a cable with a plug which is detachably fastened in a socket. Usually, the socket is located in a side wall of the room to be heated of the roasting oven.

Derartige Backöfen sind in der DE 3 104 926 A oder der US-A-3089407 gezeigt.Such ovens are in the DE 3 104 926 A or the US-A-3089407 shown.

Dieses Konzept hat jedoch eine Reihe von Nachteilen. Da im beheizten Raum des Ofens Temperaturen von mehreren 100° C auftreten, müssen sämtliche Teile der Temperaturerfassungsvorrichtung entsprechend hitzebeständig ausgebildet sein. Dies bedeutet einen verhältnismäßig hohen konstruktiven Aufwand. Insbesondere muss der Bereich um die Buchse herum thermisch hinreichend abgedichtet sein. Aus Sicherheitsgründen sollte die Vorrichtung geerdet sein, was in einem Bereich mit hohen Temperaturen einen erhöhten Aufwand bedeutet. Im beheizten Raum kann Kondensat auftreten, das beispielsweise eine Korrosion auslösen kann. Die elektrische Kontaktsicherheit lässt sich bei derart hohen Temperaturen nur mit einem erhöhten konstruktiven Aufwand gewährleisten. Es sind Abschirmelemente erforderlich, um die Vorrichtung beispielsweise vor direkter Wärmestrahlung oder Spritzflüssigkeit zu schützen. Insgesamt sind für die bekannte Vorrichtung verhältnismäßig viele Einzelteile erforderlich, was einen hohen Montage- und Kostenaufwand bewirkt.However, this concept has a number of disadvantages. Since temperatures of several 100 ° C occur in the heated space of the furnace, all parts of the temperature detection device must be designed to be heat resistant. This means a relatively high design effort. In particular, the area around the bushing must be sufficiently thermally sealed. For safety reasons, the device should be grounded, which means increased expense in a high temperature area. In the heated room condensate can occur, which can cause corrosion, for example. The electrical contact safety can be at such a high Ensure temperatures only with increased design complexity. There are shielding required to protect the device, for example, from direct heat radiation or spray liquid. Overall, relatively many items are required for the known device, which causes a high installation and cost.

Weiterhin ist die Handhabung der bekannten Vorrichtung für den Benutzer schwierig. Bei der bekannten Vorrichtung ist die Buchse in einem schwer einsehbaren Bereich angeordnet, so dass das Anschließen des Steckers an der Buchse mit Problemen behaftet sein könnte.Furthermore, the handling of the known device is difficult for the user. In the known device, the socket is arranged in a hard-to-see area, so that the connection of the plug to the socket could be problematic.

Es ist Aufgabe der Erfindung, einen Ofen mit einer Vorrichtung der eingangs genannten Art bereitzustellen, bei der gegenüber dem Stand der Technik der konstruktive Aufwand verringert und die Bedienbarkeit für den Benutzer verbessert ist.It is an object of the invention to provide a furnace with a device of the type mentioned, in which compared with the prior art, the design complexity is reduced and the operability for the user is improved.

Die Aufgabe wird durch den Gegenstand gemäß Patentanspruch 1 gelöst.The object is achieved by the subject matter of claim 1.

Für den erfindungsgemäßen Ofen ist vorgesehen, dass die Buchse am Ofen außerhalb eines beheizten oder beheizbaren Raumes angeordnet ist.For the oven according to the invention it is provided that the bush is arranged on the furnace outside of a heated or heated space.

Durch die Anordnung der Buchse in einem Bereich mit verhältnismäßig niedrigen Temperaturen können kostengünstige Standardbauteile als Buchse und Stecker verwendet werden. Auch die Korrosions- und Dichtungsprobleme, wie sie bei einer Buchse innerhalb eines beheizten Raumes auftreten würden, sind beim erfindungsgemäßen Ofen gelöst.The arrangement of the bushing in a relatively low temperature range enables inexpensive standard components to be used as a socket and plug. Also, the corrosion and sealing problems that would occur in a socket within a heated space are solved in the oven according to the invention.

Vorzugsweise ist vorgesehen, dass die Buchse neben einer Öffnung des beheizten oder beheizbaren Raumes angebracht oder anbringbar ist. Dadurch befindet sich die Buchse in einem Bereich, der für den Benutzer leicht einsehbar und zugänglich ist. Der Stecker kann auf einfache Weise in die Buchse eingeführt werden.It is preferably provided that the bush is mounted or attachable adjacent to an opening of the heated or heated space. As a result, the socket is located in an area that is easily visible and accessible to the user. The plug can be easily inserted into the socket.

Weiterhin ist vorgesehen, dass der Ofen einen Rahmen aufweist, an dem die Buchse angebracht oder anbringbar ist. Ein solcher Rahmen befindet sich in einem Bereich mit verhältnismäßig niedriger Temperatur, so dass für Buchse und Stecker kostengünstige Standardbauteile verwendbar sind.Furthermore, it is provided that the furnace has a frame to which the socket is attached or attachable. Such a frame is located in an area with relatively low temperature, so that for female and male cost standard components are used.

Vorzugsweise ist vorgesehen, dass der Rahmen eine Öffnung des beheizten oder beheizbaren Raumes zumindest teilweise umschließt. Dadurch befindet sich die Buchse in einer geometrisch vorteilhaften Position, da einerseits der Abstand zum beheizten Raum verhältnismäßig gering und andererseits die Temperatur relativ niedrig ist. Weiterhin zeichnet sich der Rahmen, der den beheizten Raum umschließt, dadurch aus, dass er für den Benutzer leicht zugänglich und einsehbar ist.It is preferably provided that the frame at least partially surrounds an opening of the heated or heated space. As a result, the socket is in a geometrically advantageous position, since on the one hand, the distance to the heated space is relatively low and on the other hand, the temperature is relatively low. Furthermore, the frame, which encloses the heated space, characterized in that it is easily accessible and visible to the user.

Ebenso kann vorgesehen sein, dass der Ofen eine Ausnehmung, Bohrung, Ausstanzung, Prägung oder dergleichen aufweist, die zur Aufnahme der Buchse vorgesehen ist. Durch eine derartige Ausnehmung oder dergleichen kann beispielsweise die Buchse lösbar in der Ausnehmung montierbar sein. Dabei besteht auch die Möglichkeit, dass der Ofen auch nachträglich mit einer Temperaturerfassungsvorrichtung nachrüstbar ist. Weiterhin besteht die Möglichkeit, dass zur Aufnahme der Buchse derartige Ausnehmungen oder dergleichen verwendet werden können, die bereits ohnehin im Ofen vorhanden sind.Likewise it can be provided that the furnace has a recess, bore, punched out, embossing or the like, which is provided for receiving the bushing. By such a recess or the like, for example, the socket can be detachably mounted in the recess. There is also the possibility that the oven can also be retrofitted with a temperature detection device. Furthermore, there is the possibility that such recesses or the like can be used to accommodate the socket, which are already present in the oven anyway.

Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Ofen eine Verarbeitungseinrichtung aufweist, die mit der Buchse gekoppelt ist. Dabei handelt es sich vorzugsweise um eine elektrische oder elektronische Schaltung. Beispielsweise kann die Verarbeitungseinrichtung zum Weiterverarbeiten temperaturabhängiger Signale vorgesehen sein.In a preferred embodiment of the invention it is provided that the oven has a processing device which is coupled to the socket. This is preferably an electrical or electronic circuit. For example, the processing device can be provided for further processing of temperature-dependent signals.

Bei einer bevorzugten Ausführungsform ist vorgesehen, dass ein erfasster Temperaturwert zum Steuern und/oder Regeln der Temperatur des beheizten Raumes vorgesehen ist.In a preferred embodiment it is provided that a detected temperature value for controlling and / or regulating the temperature of the heated space is provided.

Bei einer bevorzugten Ausführungsform weist die Verarbeitungseinrichtung eine Temperaturanzeigeeinrichtung auf. Damit hat der Benutzer die Möglichkeit, den weiteren Brat- oder Backvorgang manuell zu steuern.In a preferred embodiment, the processing device has a temperature indicator. Thus the user has the Possibility to manually control the further roasting or baking process.

Alternativ oder zusätzlich kann vorgesehen sein, dass die Verarbeitungseinrichtung eine Steuer- und/oder Regeleinrichtung zum Einstellen der Temperatur im beheizten Raum aufweist. Damit besteht die Möglichkeit, den weiteren Brat- oder Backvorgang automatisch zu steuern. Dazu kann die Verarbeitungseinrichtung auch ein Computerprogramm aufweisen. Mit einer solchen Verarbeitungseinrichtung besteht die Möglichkeit, den Brat- oder Backvorgang so zu steuern, dass ein Anbrennen oder ein fehlerhaftes Braten oder Backen verhindert wird.Alternatively or additionally, it may be provided that the processing device has a control and / or regulating device for adjusting the temperature in the heated space. This makes it possible to automatically control the further roasting or baking process. For this purpose, the processing device can also have a computer program. With such a processing device, it is possible to control the roasting or baking process so that burning or bad frying or baking is prevented.

Außerdem ist vorgesehen, dass der Stecker als Winkelstecker ausgebildet ist. Der Winkelstecker lässt sich beispielsweise in einem engen Zwischenraum zwischen Rahmen und Ofentür anordnen. Bei dem Winkelstecker handelt es sich um ein kostengünstiges Standardbauelement.It is also provided that the plug is designed as an angle plug. The angle plug can be arranged, for example, in a narrow space between the frame and the oven door. The angle plug is a low-cost standard component.

Ebenso kann vorgesehen sein, dass die elektrische Leitung als Litze ausgebildet ist. Die Litze zeichnet sich insbesondere durch eine hohe Knickfestigkeit aus, was die Funktionssicherheit erhöht. Außerdem besteht die Möglichkeit, die Litze zwischen der flexiblen Dichtung und der Ofentür einzuklemmen, ohne dass die Dichtigkeit des zu beheizenden Raumes beeinträchtigt wird.Likewise, it can be provided that the electrical line is designed as a stranded wire. The strand is characterized in particular by a high kink resistance, which increases the reliability. In addition, it is possible to clamp the strand between the flexible seal and the oven door, without the tightness of the heated space is impaired.

Aus Sicherheitsgründen kann vorgesehen sein, dass der Sensor mit einer Niederspannung beaufschlagt oder beaufschlagbar ist. Dies trägt zur Sicherheit des Benutzers und des Gerätes bei. Außerdem bedeutet die Verwendung der Niederspannung einen relativ geringen konstruktiven Aufwand.For safety reasons, it can be provided that the sensor is acted upon or acted upon by a low voltage. This contributes to the safety of the user and the device. In addition, the use of low voltage means a relatively small design effort.

Schließlich kann vorgesehen sein, dass der Ofen eine Mehrzahl von Vorrichtungen aufweist, die zum Erfassen der Temperatur im Innern eines Bratguts, Backguts oder dergleichen, vorgesehen sind. Damit kann gleichzeitig die Temperatur des Bratguts oder Backguts an mehreren Stellen unabhängig voneinander erfasst werden. Damit besteht beispielsweise die Möglichkeit, die räumliche Temperaturverteilung im beheizten Raum zu regeln.Finally, it can be provided that the furnace has a plurality of devices which are provided for detecting the temperature in the interior of a roasting product, baking stock or the like. Thus, at the same time, the temperature of the food or baking material can be detected independently at several points. This makes it possible, for example, to regulate the spatial temperature distribution in the heated space.

Weitere Merkmale, Vorteile und besondere Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Further features, advantages and particular embodiments of the invention are the subject of the dependent claims.

In der nachstehenden Figurenbeschreibung wird eine bevorzugte Ausführungsform der Erfindung unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert. Es zeigen:

In the following description of the figures, a preferred embodiment of the invention will be explained in more detail with reference to the accompanying drawings. Show it:
FIG. 1
a preferred embodiment of the apparatus of the furnace according to the invention for detecting the temperature in the interior of a roasting product, baked goods or the like; and
FIG. 2
a perspective view of a central portion of a furnace according to the invention.

In FIG 1 ist eine bevorzugte Ausführungsform der Vorrichtung des erfindungsgemäßen Ofens zum Erfassen der Temperatur dargestellt. Die Vorrichtung umfasst einen Temperatursensor 10, eine elektrische Leitung 12, einen elektrischen Stecker 14 und eine elektrische Buchse 16. Der Temperatursensor 10 ist als langgestreckter Stift ausgebildet, der in Bratgut, Backgut oder dergleichen eindringbar ist. Dazu weist der Temperatursensor 10 an seinem vorderen Ende eine Spitze auf. Die Temperatur in der Umgebung der Spitze wird vom Temperatursensor 10 erfasst. Am hinteren Ende des Temperatursensors 10 ist eine elektrische Leitung 12 angeschlossen. Die elektrische Leitung 12 ist als Litze ausgebildet. Die elektrische Leitung 12 verbindet den Temperatursensor 10 mit dem elektrischen Stecker 14. Die elektrische Buchse 16 ist kompatibel zum elektrischen Stecker 14 ausgebildet. Es ist vorgesehen, die elektrische Buchse 16 außerhalb des beheizten oder zu beheizenden Raumes an einem Ofen anzubringen. Weiterhin ist vorgesehen, dass der elektrischen Buchse 16 eine Verarbeitungseinrichtung nachgeschaltet ist, die temperaturabhängige Signale verwertet. Dabei kann es sich beispielsweise um eine Temperaturanzeigeeinrichtung handeln, von der ein Benutzer die Temperatur ablesen kann, die im Innern des Bratguts oder Backguts vorherrscht. Dies ermöglicht dem Benutzer, beispielsweise manuell den Ofen einzustellen oder die Bratzeit bzw. Backzeit festzusetzen. Ebenso kann die Verarbeitungseinrichtung als Steuerschaltung oder Regelschaltung für den Ofen ausgebildet sein. Damit kann beispielsweise die Wärmezufuhr oder der Luftdurchsatz für den beheizten Raum des Ofens eingestellt werden.In FIG. 1 a preferred embodiment of the apparatus of the invention for detecting the temperature is shown. The device comprises a temperature sensor 10, an electrical line 12, an electrical plug 14 and an electrical socket 16. The temperature sensor 10 is designed as an elongated pin, which can be penetrated into fried food, dough or the like. For this purpose, the temperature sensor 10 has a tip at its front end. The temperature in the vicinity of the tip is detected by the temperature sensor 10. At the rear end of the temperature sensor 10 is an electrical line 12th connected. The electrical line 12 is formed as a stranded wire. The electrical lead 12 connects the temperature sensor 10 to the electrical connector 14. The electrical socket 16 is compatible with the electrical connector 14. It is intended to mount the electrical socket 16 outside of the heated or heated space to a furnace. Furthermore, it is provided that the electrical socket 16 is followed by a processing device, which utilizes temperature-dependent signals. This may be, for example, a temperature indicator, from which a user can read the temperature prevailing inside the frying or baking material. This allows the user to manually set the oven, for example, or set the roasting time or baking time. Likewise, the processing device can be designed as a control circuit or control circuit for the furnace. Thus, for example, the heat supply or the air flow rate for the heated space of the furnace can be adjusted.

Es ist vorgesehen, dass lediglich der Temperatursensor 10 und derjenige Abschnitt des elektrischen Kabels 12, der sich an den Temperatursensor 10 anschließt, im beheizten Raum befinden und somit einer hohen Temperatur ausgesetzt sind. Im Gegensatz dazu befinden sich die Buchse 16 und der Stecker 14 außerhalb des beheizten Raumes des Ofens. Dadurch sind der Stecker 14 und die Buchse 16 nicht allzu hohen Temperaturen ausgesetzt, was die Verwendung von kostengünstigen Standardbauelementen für den Stecker 14 und die Buchse 16 ermöglicht. Lediglich der Temperatursensor 10 und die elektrische Leitung 12 müssen den hohen Temperaturen, die im beheizten Raum vorherrschen, standhalten. Da die elektrische Leitung 12 als Litze ausgebildet ist, kann sie beispielsweise zwischen Ofentür und Dichtung eingeklemmt werden, ohne dass eine Beschädigungsgefahr für die Leitung 12 besteht. Außerdem wird dadurch die Dichtigkeit des beheizten Raumes 20 nicht beeinträchtigt.It is envisaged that only the temperature sensor 10 and that portion of the electric cable 12, which adjoins the temperature sensor 10, are located in the heated space and thus exposed to a high temperature. In contrast, the socket 16 and the plug 14 are outside the heated space of the furnace. As a result, the plug 14 and the socket 16 are not exposed to excessive temperatures, which allows the use of inexpensive standard components for the plug 14 and the socket 16. Only the temperature sensor 10 and the electrical lead 12 must withstand the high temperatures prevailing in the heated space. Since the electrical line 12 is formed as a strand, it can be clamped, for example, between the oven door and seal without a Risk of damage to the line 12 is. In addition, the tightness of the heated space 20 is not affected thereby.

In FIG 2 ist eine Perspektivansicht des zentralen Bereiches des erfindungsgemäßen Ofens dargestellt. Der Ofen umfasst einen beheizbaren Raum 20, dessen Vorderseite eine Öffnung 18 aufweist und dessen übrige Seiten abgeschlossen sind. Die Öffnung 18 ist mittels einer nicht dargestellten Ofentür abschließbar. Die Öffnung 18 umfasst eine flexible Dichtung 24, die die Öffnung 18 vollständig umschließt. Die Dichtung 24 ist dazu vorgesehen, den beheizbaren Raum 20 zur Ofentür hin abzudichten. Die Öffnung 18 ist von einem Rahmen 22 umschlossen. Der Rahmen 22 dient insbesondere zur Montage des beheizbaren Raumes 20. Außerdem ist an dem Rahmen 22 die Ofentür montierbar. Die Buchse 16 ist ebenfalls am Rahmen 22 angeordnet. Die Buchse 16 befindet sich ebenso wie der Rahmen 22 außerhalb des beheizten Raumes 20, so dass diese nur verhältnismäßig niedrigen Temperaturen ausgesetzt sind. Der Stecker 14 befindet sich in der Buchse 16, so dass auch dieser keiner hohen Temperatur ausgesetzt ist. Lediglich die elektrische Leitung 12 und der Temperatursensor 10 sind zum Einsatz innerhalb des beheizten Raumes 20 vorgesehen. Dies bedeutet, dass für den Stecker 14 und die Buchse 16 kostengünstige Standardbauelemente verwendet werden können. Da die Buchse 16 im Rahmen 22 und nicht im beheizbaren Raum 20 installiert ist, werden von der Buchse 16 keine Korrosionsprobleme, Dichtungsprobleme und dergleichen verursacht.In FIG. 2 is a perspective view of the central region of the furnace according to the invention shown. The oven comprises a heatable space 20, the front side of which has an opening 18 and the remaining sides of which are closed. The opening 18 is lockable by means of an oven door, not shown. The opening 18 includes a flexible seal 24 that completely encloses the opening 18. The seal 24 is intended to seal the heatable space 20 towards the oven door. The opening 18 is enclosed by a frame 22. The frame 22 is used in particular for mounting the heatable space 20. In addition, the oven door can be mounted on the frame 22. The bush 16 is also arranged on the frame 22. The sleeve 16 is located as well as the frame 22 outside the heated space 20, so that they are exposed to relatively low temperatures. The plug 14 is located in the socket 16, so that this is not exposed to high temperature. Only the electrical line 12 and the temperature sensor 10 are provided for use within the heated space 20. This means that cost-effective standard components can be used for the plug 14 and the socket 16. Since the bush 16 is installed in the frame 22 and not in the heatable space 20, no corrosion problems, sealing problems and the like are caused by the bush 16.

Weiterhin kann die Buchse 16 im Rahmen 22 innerhalb einer Ausnehmung, Prägung, Bohrung, Ausstanzung oder dergleichen angeordnet sein, die auf einfache Weise herstellbar sind. Die Buchse 16 kann auch im Rahmen 22 innerhalb einer Ausnehmung angeordnet sein, die ohnehin schon im Rahmen 22 vorhanden ist. Dieses Konzept ermöglicht einem Hersteller, den Rahmen 22 für verschiedene Öfen sowohl mit als auch ohne Temperaturerfassungsvorrichtung anzubieten, wobei der Mehraufwand für eine Montage der Temperaturerfassungsvorrichtung sehr gering ist. Auch das Auswechseln der Temperaturerfassungsvorrichtung lässt sich auf einfache Weise durchführen.Furthermore, the sleeve 16 may be arranged in the frame 22 within a recess, embossing, bore, punching or the like, which can be produced in a simple manner. The bushing 16 can also be in the frame 22 within a recess be arranged, which is already present in the frame 22 anyway. This concept allows a manufacturer to offer the frame 22 for various ovens both with and without a temperature sensing device, with very little overhead for mounting the temperature sensing device. Also, the replacement of the temperature sensing device can be carried out in a simple manner.

Die Anordnung der Buchse 16 im Rahmen 22 hat weiterhin den Vorteil, dass für den Benutzer die Buchse 16 ohne weiteres einsehbar und zugänglich ist. Dadurch lässt sich auf einfache Weise der Stecker 14 mit dem Temperatursensor 10 anschließen und wieder abklemmen.The arrangement of the socket 16 in the frame 22 also has the advantage that the socket 16 is readily visible and accessible to the user. This makes it easy to connect the plug 14 with the temperature sensor 10 and disconnect again.

Bei einer weiteren Ausgestaltung der Erfindung kann ein Ofen mehrere Temperaturerfassungsvorrichtungen aufweisen. Dabei könnten beispielsweise im Rahmen 22 mehrere Buchsen 16 angeordnet sein, an denen mehrere Stecker 14 mit angekoppelten Temperatursensoren 10 anschließbar sind. Damit besteht die Möglichkeit, gleichzeitig an mehreren Stellen des Bratguts oder Backguts die Innentemperatur zu erfassen. Dies ist insbesondere dann vorteilhaft, wenn die Temperatur im beheiz-baren Raum 20 lokal abhängig einstellbar ist.In a further embodiment of the invention, a furnace may have a plurality of temperature sensing devices. In this case, for example, could be arranged in the frame 22 a plurality of sockets 16 to which a plurality of plugs 14 with coupled temperature sensors 10 are connectable. This makes it possible to simultaneously detect the internal temperature at several points of the food or baking stock. This is particularly advantageous if the temperature in the heatable chamber 20 is locally dependent adjustable.
