Abstract
A dental furnace (10) for dental restorations comprising a firing chamber into which, in particular between a furnace bottom part (14) and a furnace upper part (12), the dental restoration, in particular within a muffle, can be introduced, and a sensor that is connected with a control device (52) for the dental furnace (10), wherein the sensor, in particular the temperature sensor (22), is arranged outside the firing chamber and comprises a detection range (40) that also extends outside the firing chamber.
Claims22
A dental furnace for dental restorations comprising
- a furnace bottom part,
- a furnace upper part,
- a firing chamber having a muffle into which the dental restoration can be introduced, and
- a temperature sensor that is connected with a control device for the dental furnace,
- wherein the temperature sensor is arranged outside the firing chamber and comprises a detection range that also extends outside the firing chamber,
- wherein the temperature sensor responds to objects that are located within the detection range and which have an elevated temperature, and
- wherein the detection range of the temperature sensor enlarges in a direction transverse to the temperature sensor if starting from the temperature sensor, and that the detection range extends obliquely to a lateral surface of the dental furnace.
