Gargeräte sind ebenfalls grundsätzlich im Stand der Technik in unterschiedlichsten Ausführungsformen bekannt. So sind insbesondere Gartiegel, wie sie insbesondere unter dem Handelsnamen Va-rioCookingCenter® vertrieben werden, mit einer Heizplatte zum Aufheizen eines Tiegelbodens im Stand der Technik bekannt.Cooking appliances are also basically known in the prior art in various embodiments.

Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 bis 19 beschrieben.Advantageous developments are described in claims 2 to 19.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, dass in einem Gargerät eine Berührungsfläche eines Sensors eines Thermoelements mit einer Wand, deren Oberflächentemperatur zu messen ist, insbesondere durch Anlegen einer definierten Anpresskraft komplett, kontaktierbar ist, und seitliche Temperatureinflüsse auf den Sensor, insbesondere durch Wärmestrahlung von einem die Wand aufheizenden Heizelement, ebenso wie Wärmebrücken, wie zwischen dem Sensor und einer das Thermoelement an der Wand haltenden Befestigungseinrichtung, durch Anordnen des Sensors an einem Halteglied mit einer schlechten Wärmeleitfähigkeit, also aus einem thermischen Isolationsmaterial im wesentlichen vermieden werden können, so dass die Oberflächentemperatur der Wand mit hoher Genauigkeit gemessen werden kann. Das erfindungsgemäße Thermoelement weist also eine definierte Berührungsfläche zum Kontaktieren besagter Wand auf. Das Halteglied des Thermoelements drückt zudem nach Art eines Stempels den Sensor unter Federvorspannung auf die Wand.The invention is based on the surprising finding that in a cooking appliance, a contact surface of a sensor of a thermocouple with a wall, the surface temperature is measured, in particular by applying a defined contact force completely, contactable, and lateral temperature influences on the sensor, in particular by thermal radiation of a heating element heating the wall, as well as thermal bridges, as between the sensor and a thermocouple to the wall holding fastener, can be substantially avoided by arranging the sensor on a holding member having a poor thermal conductivity, ie from a thermal insulation material, so that the Surface temperature of the wall can be measured with high accuracy.

Die Heizplatte 10 ist ihrerseits über eine Befestigungseinrichtung an dem Tiegelboden 1 angebracht, die eine Schraubverbindung mit vier Schrauben 15, jeweils in Wirkverbindung mit einer Mutter 17 und zwei Unterlegscheiben 14, 16, darstellt. Das Rechteck der Heizplatte 10 ist in vier rechteckige Abschnitte unterteilt, in denen jeweils eine Schraube 15 mittig verläuft, um so einen gleichmäßigen Andruck der Heizplatte 10 an dem Tiegelboden 1 zu erreichen. Zur weiteren Vergleichmäßigung des Andruckes der Heizplatte 10 an dem Tiegelboden 1 ist zumindest eine der Unterlegscheiben vergrößert ausgeformt, und zwar ist die Unterlegscheibe 14 mit einem kreisförmigen Umfang bereitgestellt, der sich über einen Großteil des jeweiligen rechteckigen Abschnitts des Rechtecks der Heizplatte 10 erstreckt, wie in Figur 2 dargestellt.The heating plate 10 is in turn attached via a fastening device to the crucible bottom 1, which is a screw connection with four screws 15, in each case in operative connection with a nut 17 and two washers 14, 16. The rectangle of the heating plate 10 is divided into four rectangular sections, in each of which a screw 15 extends centrally, so as to achieve a uniform pressure of the heating plate 10 on the crucible bottom 1. To further even out the pressure of the heating plate 10 on the crucible bottom 1, at least one of the washers is formed enlarged, namely, the washer 14 is provided with a circular circumference extending over a majority of the respective rectangular portion of the rectangle of the heating plate 10, as shown in FIG FIG. 2 shown.

Das Thermoelement 100 ist mittig innerhalb der Heizplatte 10 angeordnet, und zwar mit gleichem Abstand zu jeder der vier Schrauben 15, wie auch am besten in Figur 2 zu sehen ist.The thermocouple 100 is located centrally within the heating plate 10, equidistant from each of the four screws 15, as well as best in FIG FIG. 2 you can see.

Das Thermoelement 100 besteht aus einer Hülse 101, einem Stempel 102, einem Edelstahlplättchen 103 und Kabeln 104a, 104b, siehe Figuren 3 und 4. Genauer gesagt ist das in Draufsicht im wesentlichen kreisförmige, den eigentlichen Sensor darstellende, Edelstahlplättchen 103 auf einer Aufliegefläche eines Kopfes 102a1 des Stempels 102 angeordnet. Das Edelstahlplättchen 103 weist auf seiner der Aufliegefläche des Kopfes 102a1 gegenüberliegenden Seite eine Berührungsfläche zum Kontaktieren des Tiegelbodens 1, wie in Figur 1 dargestellt ist, auf. Auf das Edelstahlplättchen 103 sind auf der der Auflagefläche zugewandten Seite ferner zwei Kabeln 104a aufgeschweißt, die, mit PTFE isoliert, in Schlitzen 102b des Stempels 102 bereichsweise geführt sind. Nach Verlassen der Schlitze 102b sind die Kabel 104b durch eine Hülle aus Silikon weiter isoliert und geschützt, und verlaufen zwischen einem Stiel 102a2 des Stempels 102 sowie der Hülse 101, um schließlich aus der Hülse 101 auszutreten, siehe Figur 3. Die Kabel 104a, 104b dienen somit auch dem Halten der Hülse 101 auf dem Stempel 102, nämlich im Bereich des Stiels 102a2, der einen deutlich geringeren Querschnitt als der Kopf 102a1 des Stempels 102 aufweist.The thermocouple 100 consists of a sleeve 101, a punch 102, a stainless steel plate 103 and cables 104a, 104b, see Figures 3 and 4 , More precisely, the stainless steel plate 103, which is essentially circular in plan view and represents the actual sensor, is arranged on a resting surface of a head 102a1 of the punch 102. The stainless steel plate 103 has on its side opposite the support surface of the head 102a1 side a contact surface for contacting the crucible bottom 1, as in FIG. 1 is shown on. On the stainless steel plate 103, two cables 104a are further welded on the side facing the support surface, which, isolated with PTFE, in regions 102b of the punch 102 are partially guided. After leaving the slots 102b, the cables 104b are further insulated and protected by a sheath of silicone and extend between a stem 102a2 of the punch 102 and the sleeve 101 to finally exit the sleeve 101, see FIG. 3 , The cables 104a, 104b thus also serve to hold the sleeve 101 on the punch 102, namely in the region of the stem 102a2, which has a significantly smaller cross-section than the head 102a1 of the punch 102.

Der Stempel 102 samt Edelstahlplättchen 103 und Kabeln 104a ist in Figur 3 in die Hülse 101 eingeführt zu sehen. Demnach liegt der Kopf 102a1 des Stempels 102 auf einem Ende der Hülse 101 auf. Die Hülse 101 ist dabei im wesentlichen hohlzylindrisch ausgeformt, weist also einen Hohlzylinder 101b auf, und zwar mit einem Innendurchmesser, der kleiner als der Außendurchmesser des Kopfes 102a1 des Stempels 102 ist, jedoch groß genug für die Beherbergung des Stiels 102a2 des Stempels 102 samt Kabel 104a. Zudem weist die Hülse 101 einen Bereich mit vergrößertem Durchmesser auf, der im Folgenden Kragen 101a genannt wird.The stamp 102 together with stainless steel plate 103 and cables 104a is in FIG. 3 to see introduced into the sleeve 101. Accordingly, the head 102a1 of the punch 102 is located on one end of the Sleeve 101 on. The sleeve 101 is formed substantially hollow cylindrical, thus has a hollow cylinder 101b, with an inner diameter which is smaller than the outer diameter of the head 102a1 of the punch 102, but large enough for the harboring of the stem 102a2 of the punch 102 together with cable 104a. In addition, the sleeve 101 has an area with an enlarged diameter, which is referred to below collar 101 a.

Das Thermoelement 100 ist über eine Federklemme 110 relativ zum Tiegelboden 1 fixierbar, wie in Figur 1 dargestellt. Die Heizplatte 10 weist zu diesem Zwecke zusätzlich zu Aussparungen 10a für die Schrauben 15 eine Aussparung 10b für das Thermoelement 100 auf, so dass das Edelstahlplättchen 103 den Tiegelboden 1 mit einer definierten Berührungsfläche kontaktieren kann. Die Federklemme 110 drückt dabei gegen den Kragen 101a der Hülse 101 und sorgt somit für eine definierte Anpresskraft, während die Ausgestaltung der Hülse 101 sowie auch des Stempels 102 aus Keramik dafür sorgt, dass seitliche Temperatureinflüsse auf das Thermoelement 100 durch die Heizplatte 10 vernachlässigbar gering sind. Zudem stellen die Hülse 101 und der Stempel 102 aufgrund ihrer schlechten Wärmeleitung sicher, dass im wesentlichen keine Wärmebrücken über die Federklemme 110 zum Edelstahlplättchen 103 überschlagen können.The thermocouple 100 is fixed via a spring clip 110 relative to the crucible bottom 1, as in FIG. 1 shown. The heating plate 10 has for this purpose in addition to recesses 10a for the screws 15 a recess 10b for the thermocouple 100, so that the stainless steel plate 103 can contact the crucible bottom 1 with a defined contact surface. The spring clip 110 presses against the collar 101a of the sleeve 101 and thus ensures a defined contact pressure, while the design of the sleeve 101 and the ceramic stamp 102 ensures that lateral temperature influences on the thermocouple 100 by the heating plate 10 are negligible , In addition, the sleeve 101 and the punch 102, due to their poor heat conduction, ensure that substantially no thermal bridges can roll over the spring clip 110 to the stainless steel plate 103.

Die Federklemme 110 ist in Figur 5 im Detail dargestellt und umfasst danach sieben Teilbereiche. Von diesen sieben Teilbereichen sind drei im wesentlichen eben ausgebildet und stellen Andrückbereiche 111a, 111b1, 111b2 dar, die über Biegekanten 112a1 bis 112b22 mit unter Vorspannung stehenden, weiteren Teilbereichen verbunden sind, von denen jeweils zwei sich im wesentlichen V-förmig in Figur 5 nach oben erstrecken. An ihren beiden Enden weist die Federklemme 110 somit jeweils einen Andrückbereich 111b1, 111b2 mit einem Loch 110b zur Fixierung zwischen Unterlegscheiben 14 und 17 der Befestigungseinrichtung bei festgedrehten Muttern 16 auf den entsprechenden Schrauben 15 auf, siehe Figur 1. An diese ersten Andrückbereiche 111b1, 111b2 schließt sich jeweils über eine Biegekante 112b11, 112b12 ein sich von der Heizplatte 10 weg erstreckender Teilbereich an, an den sich nach einer weiteren Biegekante 112b21, 111b22 ein weiterer Teilbereich jeweils anschließt, der wieder zur Heizplatte 10 geneigt ist. Die beiden zur Heizplatte geneigten Teilbereiche grenzen über Biegekanten 112a2 und 112a1 an einen zweiten, ebenen Andrückbereich 111a an. In dem zweiten Andrückbereich 111a ist ein Abschnitt 110a2 eines zweiten Lochs bzw. Doppellochs 110a angeordnet, in dem das Thermoelement 100 in Figur 1 fixiert dargestellt ist.The spring clip 110 is in FIG. 5 presented in detail and then includes seven subareas. Of these seven subregions, three are substantially planar and constitute pressure regions 111a, 111b1, 111b2, which are connected via bending edges 112a1 to 112b22 with prestressed, further subregions, two of which are substantially V-shaped in FIG. 5 extend upwards. At its two ends, the spring clip 110 thus has a respective pressure region 111b1, 111b2 with a hole 110b for fixing between washers 14 and 17 of the fastening device with nuts 15 tightened on the corresponding screws 15, see FIG. 1 , A partial region extending away from the heating plate 10 adjoins these first pressing regions 111b1, 111b2 via a bending edge 112b11, 112b12, to which, after another bending edge 112b21, 111b22, another subregion adjoins, which is inclined again to the heating plate 10 , The two subregions inclined to the heating plate adjoin via bend edges 112a2 and 112a1 to a second, flat pressure region 111a. In the second pressing portion 111a is a Section 110a2 of a second hole or double hole 110a arranged in which the thermocouple 100 in FIG. 1 is shown fixed.

Zur Fixierung des Thermoelements 100 in dem Lochabschnitt 110a2 ist das Thermoelement 100, mit seinem Edelstahlplättchen 103 zuerst, in einen ersten Abschnitt 110a1 des zweiten Loches 110a einzuführen, und zwar bis der Kragen 101a den ersten Lochabschnitt 110a1 der Federklemme 110 passiert hat. Sodann kann das Thermoelement 100 in den zweiten Lochabschnitt 110a2 verschoben werden, so dass die Federklemme 110 im zweiten Andrückbereich 111b auf dem Kragen 101a aufliegt, siehe Figur 1. Die Federklemme 110 kann entweder mit dem Thermoelement 100 vormontiert und sodann zwischen den Unterlegscheiben 14 und 17 befestigt werden. Alternativ dazu kann die Federklemme 110 zwischen den Unterlegscheiben 14 und 17 vormontiert, aber nicht fest eingespannt sein, so dass dann das Thermoelement 100 mit der Federklemme 110 verbindbar ist, und im Anschluss durch Festschrauben der Muttern 16 auf den jeweiligen Schrauben 15 die Federklemme 110 fest eingespannt werden kann.For fixing the thermocouple 100 in the hole portion 110a2, the thermocouple 100, with its stainless steel plate 103 at first, is to be inserted into a first portion 110a1 of the second hole 110a until the collar 101a has passed through the first hole portion 110a1 of the spring clip 110. Then, the thermocouple 100 can be shifted into the second hole portion 110a2, so that the spring clip 110 rests on the collar 101a in the second pressing portion 111b, see FIG FIG. 1 , The spring clip 110 may be preassembled with either the thermocouple 100 and then secured between the washers 14 and 17. Alternatively, the spring clip 110 may be preassembled between the washers 14 and 17, but not clamped tightly, so that then the thermocouple 100 is connectable to the spring clip 110, and then by tightening the nuts 16 on the respective screws 15, the spring clip 110 firmly can be clamped.

Das erfindungsgemäße Thermoelement 100 weist eine geringe Masse der einzelnen Komponenten auf und ist einfach montierbar, um mit hoher Genauigkeit die Oberflächentemperatur des Tiegelbodens 1 zu messen, so dass ein sich auf dem Tiegelboden 1, und zwar auf der der Heizplatte 10 abgewandten Seite, angeordnetes, nicht gezeigtes Gargut, wie Rührei oder dergleichen, über den Tiegelboden 1 gleichmäßig erhitzbar ist.The inventive thermocouple 100 has a low mass of the individual components and is easy to assemble to measure with high accuracy, the surface temperature of the crucible bottom 1, so that on the crucible bottom 1, on the heating plate 10 side facing away, arranged, not shown Gargut, such as scrambled eggs or the like, on the crucible bottom 1 is uniformly heated.

Die in der vorstehenden Beschreibung, den Ansprüchen sowie den Zeichnungen offenbarten Merkmale können sowohl einzeln als auch in jeder beliebigen Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features disclosed in the foregoing description, the claims and the drawings may be essential both individually and in any combination for the realization of the invention in its various embodiments.
