Darüber hinaus ist aus der WO 2004/106899 A1 eine Ausgestaltung bekannt, bei der drahtlos optische Signale bei einer Messeinrichtung zur Erfassung einer Temperatur im Inneren eines Garguts übertragen werden.

In addition, WO 2004/106899 A1 discloses an embodiment in which wirelessly optical signals are transmitted in a measuring device for detecting a temperature in the interior of a food. However, the functionality of this known measuring device with regard to wireless communication is limited.

It is an object of the present invention to provide a measuring device for detecting in particular a temperature inside a food, a device with such a measuring device and a domestic appliance for preparing food, at or in which the wireless communication can be made extended, and to provide a method for operating a measuring device.

Eine erfindungsgemäße Messvorrichtung zur Erfassung insbesondere einer Temperatur im Inneren eines Garguts umfasst eine optische Signalübertragungsvorrichtung, welche zur drahtlosen Kommunikation mit einer extern zur Messvorrichtung angeordneten Sende- und/oder Empfangseinheit ausgebildet ist. Die optische Signalübertragungsvorrichtung ist zum Senden von optischen Datensignalen und zum Empfangen von optischen Energieversorgungssignalen für die Energieversorgung der Signalübertragungsvorrichtung aus- gebildet. Es können also eine Mehrzahl unterschiedlicher Signale drahtlos empfangen und gesendet werden, so dass zum einen die über die Temperatur im Inneren des Garguts mit der Messvorrichtung erhaltenen Daten in optischen Datensignalen gesendet werden und andererseits darüber hinaus zur Energieversorgung der Signalübertragungsvorrichtung selbst extern entsprechende Energieversorgungssignale im optischen Spektral- bereich erfasst werden. Messgrößen können auch eine Feuchte, ein Fettgehalt eines Gargutes oder andere Parameter sein. A measuring device according to the invention for detecting in particular a temperature inside a food to be cooked comprises an optical signal transmission device, which is designed for wireless communication with a transmitting and / or receiving unit arranged externally to the measuring device. The optical signal transmission device is designed to transmit optical data signals and to receive optical energy supply signals for the power supply of the signal transmission device. Thus, a plurality of different signals can be received and transmitted wirelessly, so that, on the one hand, the data obtained via the temperature inside the food with the measuring device are transmitted in optical data signals and, on the other hand, to the energy supply of the signal transmission device itself, corresponding external energy supply signals in the optical spectrum - area are recorded. Measured variables can also be a moisture, a fat content of a food or other parameters.
Vorzugsweise sind als optische Signale derartige verstanden, die eine Wellenlänge im für das menschliche Auge sichtbaren Spektralbereich aufweisen. Preferably understood as optical signals such that have a wavelength in the visible to the human eye spectral range.
Durch eine derartige Ausgestaltung der Messvorrichtung kann diese mit umfänglicher Kommunikation drahtlos betrieben werden, was besonders vorteilhaft bei der Verwendung in einem Garraum eines Hausgeräts zum Zubereiten von Lebensmitteln ist. Da darüber hinaus alle unterschiedlichen gesendeten und empfangenen Datensignale optische Sig- nale sind, ist auch die Verwendung dieser Messvorrichtung beispielsweise in Mikrowellengeräten problemlos möglich.
Vorzugsweise ist die Messvorrichtung ein Temperaturspieß, der in das Gargut einsteckbar ist. By such a configuration of the measuring device, it can be operated wirelessly with extensive communication, which is particularly advantageous when used in a cooking chamber of a domestic appliance for preparing food. Moreover, since all the different transmitted and received data signals are optical signals, the use of this measuring device, for example in microwave ovens, is also possible without problems. Preferably, the measuring device is a temperature spit that can be inserted into the food.
Vorzugsweise ist die optische Signalübertragungsvorrichtung mit einem Elektronikmodul ausgebildet, welches in einer Spitze des Temperaturspießes angeordnet ist. Insbesonde- re ist dieses Elektronikmodul daher sehr klein und Platz sparend ausgebildet und ermöglicht eine sehr präzise Temperaturerfassung. Preferably, the optical signal transmission device is formed with an electronic module, which is arranged in a tip of the temperature spit. In particular, this electronic module is therefore very small and space-saving design and enables a very precise temperature detection.
Insbesondere umfasst das Elektronikmodul dazu einen Temperatursensor und eine eigene Energieversorgungseinheit und darüber hinaus eine Signalverarbeitungseinheit, wel- che zur Signalverarbeitung und Signalübertragung und somit -aussendung ausgebildet ist. In diesem relativ kleinen Elektronikmodul sind daher unterschiedliche elektronische Bauteile angeordnet beziehungsweise integriert und insbesondere eine eigene Energieversorgung über optische Energieversorgungssignale kann gewährleistet werden. Vorzugsweise ist das Elektronikmodul direkt mit einem Lichtleiter in der Messvorrichtung optisch gekoppelt. In particular, the electronic module for this purpose comprises a temperature sensor and a separate power supply unit and, moreover, a signal processing unit which is designed for signal processing and signal transmission and thus transmission. In this relatively small electronic module therefore different electronic components are arranged or integrated and in particular a separate power supply via optical power supply signals can be ensured. Preferably, the electronic module is optically coupled directly to a light guide in the measuring device.
Vorzugsweise umfasst die Signalübertragungsvorrichtung einen Lichtleiter, welcher sich vom Griff des Temperaturspießes bis zur Spitze im Inneren des Temperaturspießes er- streckt. Dadurch kann zum einen eine bestmögliche Positionierung für das Elektronikmodul im Hinblick auf die Temperaturerfassung ermöglicht werden und darüber hinaus eine sehr gezielte umfängliche optische Signalleitung im Temperaturspieß über eine möglichst große Strecke verlustfrei gewährleistet werden, um diese optischen Signale dann an der geeignetsten Stelle des Temperaturspießes drahtlos auszusenden und entsprechende Energieversorgungssignale zu empfangen. Preferably, the signal transmission device comprises a light guide, which extends from the handle of the temperature spit to the tip in the interior of the temperature spit. As a result, on the one hand, the best possible positioning for the electronic module with respect to temperature detection is made possible and, moreover, a very targeted circumferential optical signal line in the temperature spike can be ensured lossless over as large a distance as possible in order to wirelessly emit these optical signals at the most suitable point of the temperature spit and receive corresponding power supply signals.
Vorzugsweise weist die Signalübertragungsvorrichtung eine Einkoppellinse auf, welche am hinteren Ende eines Griffs des Temperaturspießes angeordnet und mit einem Lichtleiter optisch gekoppelt ist. Dadurch kann sowohl die Auskopplung der zu sendenden Da- tensignale über eine drahtlose Schnittstelle als auch der Empfang von drahtlos gesendeten und von der Messvorrichtung empfangenen optischen Energieversorgungssignalen besonders geeignet erfolgen. Darüber hinaus ist diese Position der Einkoppellinse gerade für das Empfangen und das Senden der Signale eine besonders bevorzugte Position.
Des Weiteren betrifft die Erfindung eine Einrichtung für ein Hausgerät zum Zubereiten von Lebensmitteln mit einer erfindungsgemäßen Messvorrichtung oder einer vorteilhaften Ausgestaltung davon. Die Einrichtung umfasst darüber hinaus eine extern zur Messvorrichtung angeordnete Sende- und/oder Empfangseinheit, welche zum Empfangen der optischen Datensignale der Messvorrichtung und zum Senden der optischen Energieversorgungssignale ausgebildet ist. Preferably, the signal transmission device has a coupling lens, which is arranged at the rear end of a handle of the temperature spike and optically coupled to a light guide. As a result, both the decoupling of the data signals to be transmitted via a wireless interface and the reception of wirelessly transmitted optical energy supply signals received by the measuring device can take place particularly suitably. Moreover, this position of the coupling lens is a particularly preferred position for receiving and transmitting the signals. Furthermore, the invention relates to a device for a household appliance for preparing food with a measuring device according to the invention or an advantageous embodiment thereof. The device furthermore comprises a transmitting and / or receiving unit which is arranged externally to the measuring device and which is designed to receive the optical data signals of the measuring device and to transmit the optical power supply signals.
Vorzugsweise ist die Sende- und/oder Empfangseinheit zur Kommunikation mit einer extern zur Messvorrichtung angeordneten Steuereinheit ausgebildet. Insbesondere ist die Sende- und/oder Empfangseinheit an einer Deckenwand einer einen Garraum des Hausgeräts begrenzenden Muffel angeordnet. Die Steuereinheit ist diesbezüglich insbesondere beabstandet außerhalb der Muffel angeordnet. Zum einen kann dadurch die bestmögliche und verlustärmste Übertragung der optischen Signale erfolgen und darüber hinaus wird die Steuereinheit im Hinblick auf ihre Funktionalität durch die im Garraum entstehende Wärme nicht beeinträchtigt. Preferably, the transmitting and / or receiving unit is designed for communication with a control unit arranged externally to the measuring device. In particular, the transmitting and / or receiving unit is arranged on a ceiling wall of a cooking chamber of the household appliance limiting muffle. The control unit is arranged in this regard, in particular spaced outside the muffle. On the one hand, the best possible and lowest-loss transmission of the optical signals can take place and, moreover, the control unit is not impaired in terms of its functionality by the heat generated in the cooking chamber.

The lens 7 is formed at a rear end 8 of the handle 2 and optically coupled to the light guide 6, in particular directly connected thereto. The light guide 6 extends inside the handle 2 and the rod 3 and extends to a tip 9 of the measuring device first In the tip 9, an electronic module 10 is arranged, which is optically coupled to the light guide 6. The electronic module 10 includes a temperature sensor 1 1, a power supply unit 12 and a signal processing unit 13. By the power supply unit 12, the electronic module 10 is supplied with energy, with optical power supply signals on the Transmitting and / or receiving unit 4 are sent and received by the measuring device 1.
