Claims (5)
- Glühkerze (10), umfassend:ein Metallrohr (40, 70), das sich entlang einer Axiallinie (O) erstreckt, wobei ein vorderes Ende des Rohrs (40, 70) in eine Axiallinienrichtung geschlossen ist; undeine wärmeerzeugende Spule (50, 80), die in dem Rohr (40, 70) angeordnet ist und hauptsächlich aus Wolfram gebildet ist, wobei ein eingebetteter Abschnitt (53, 82) in einem vorderen Endabschnitt der wärmeerzeugenden Spule (50, 80) in einem vorderen Endabschnitt (41, 71) des Rohrs (40, 70) eingebettet ist,wobei die wärmeerzeugende Spule (50, 80) einen spiralförmigen Abschnitt (51, 81) beinhaltet, der mindestens einen Teil des eingebetteten Abschnitts (53, 82) beinhaltet und der kontinuierlich aus dem eingebetteten Abschnitt (53, 82) zu einer Innenseite des Rohrs (40, 70) gebildet ist, dadurch gekennzeichnet, dass:
in der wärmeerzeugenden Spule (50, 80), die in einem Längsabschnitt der Glühkerze (10) einschließlich der Axiallinie (O) vorhanden ist, ein erster Durchschnittswert, der durch Teilen einer ersten Summe, die eine Summe aus Flächen von Querschnitten des spiralförmigen Abschnitts (51, 81) in dem eingebetteten Abschnitt (53, 82) ist, durch die Anzahl der Querschnitte des spiralförmigen Abschnitts (51, 81) in dem eingebetteten Abschnitt (53, 82) berechnet ist, kleiner als ein zweiter Durchschnittswert ist, der durch Teilen einer zweiten Summe, die eine Summe aus Flächen von Querschnitten des spiralförmigen Abschnitts (51, 81) in dem Rohr (40, 70) ist, durch die Anzahl der Querschnitte des spiralförmigen Abschnitts (51, 81) in dem Rohr (40, 70) berechnet ist. - Glühkerze (10) nach Anspruch 1,
wobei ein verschmolzener Abschnitt (56, 87), in dem der eingebettete Abschnitt (53, 82) und der vordere Endabschnitt (41, 71) des Rohrs (40, 70) miteinander verschmolzen sind, gebildet ist, und
wobei, in der wärmeerzeugenden Spule (50, 80), die in dem Längsabschnitt der Glühkerze (10) einschließlich der Axiallinie (O) vorhanden ist, ein dritter Durchschnittswert, der durch Teilen einer Summe aus einer Summe aus Flächen von Querschnitten des verschmolzenen Abschnitts (56, 87) und der ersten Summe durch die Anzahl der Querschnitte des spiralförmigen Abschnitts (51, 81) in dem eingebetteten Abschnitt (53, 82) berechnet ist, kleiner als der zweite Durchschnittswert ist. - Glühkerze (10) nach Anspruch 1 oder 2, wobei, in der wärmeerzeugenden Spule (50, 80), die in dem Längsabschnitt der Glühkerze (10) einschließlich der Axiallinie (O) vorhanden ist, jede der Flächen der Querschnitte des spiralförmigen Abschnitts (51, 81) in dem Rohr (40, 70) 1,3-mal der erste Durchschnittswert oder kleiner ist.
- Glühkerze (10) nach einem der Ansprüche 1 bis 3,
wobei der vordere Endabschnitt (71) des Rohrs (70) einen konvexen Abschnitt (71a) beinhaltet, der nach innen konvex ist, und
wobei, in der wärmeerzeugenden Spule (80), die in dem Längsabschnitt der Glühkerze (10) einschließlich der Axiallinie (O) vorhanden ist, ein vierter Durchschnittswert, der durch Teilen einer dritten Summe, die eine Summe aus Flächen von Querschnitten eines ersten spiralförmigen Abschnitts (83, 84) ist, der ein Abschnitt des spiralförmigen Abschnitts (81) in dem Rohr (70) ist, wovon mindestens ein Teil um den konvexen Abschnitt (71a) herum angeordnet ist, durch die Anzahl der Querschnitte des ersten spiralförmigen Abschnitts (83, 84) berechnet ist, kleiner als ein fünfter Durchschnittswert ist, der durch Teilen einer Differenz zwischen der zweiten Summe und der dritten Summe durch eine Differenz zwischen der Anzahl der Querschnitte des spiralförmigen Abschnitts (81) in dem Rohr (70) und der Anzahl der Querschnitte des ersten spiralförmigen Abschnitts (83, 84) berechnet ist. - Glühkerze (10) nach einem der Ansprüche 1 bis 3, wobei, in der wärmeerzeugenden Spule (50, 80), die in dem Längsabschnitt der Glühkerze (10) einschließlich der Axiallinie (O) vorhanden ist, ein sechster Durchschnittswert, der durch Teilen einer vierten Summe, die eine Summe aus Flächen von Querschnitten eines zweiten spiralförmigen Abschnitts (83, 84, 85) ist, der ein Abschnitt des spiralförmigen Abschnitts (51, 81) in dem Rohr (40, 70) ist, wovon mindestens ein Teil innerhalb von 3 mm von dem vorderen Ende (46, 75) des Rohrs (40, 70) zu einer Rückseite angeordnet ist, durch die Anzahl der Querschnitte des zweiten spiralförmigen Abschnitts (83, 84, 85) berechnet ist, kleiner als ein siebter Durchschnittswert ist, der durch Teilen einer Differenz zwischen der zweiten Summe und der vierten Summe durch eine Differenz zwischen der Anzahl der Querschnitte des spiralförmigen Abschnitts (51, 81) in dem Rohr (40, 70) und der Anzahl der Querschnitte des zweiten spiralförmigen Abschnitts (83, 84, 85) berechnet ist.
