A temperature detection device for detecting the bottom temperature of cookware on a cooking hob

摘要

The present invention relates to a temperature detection device for detecting the bottom temperature of cookware on a cooking hob (10). The temperature detection device comprises a pad (16) formed as a flat sheet. The pad (16) is provided for covering at least one cooking zone of the cooking hob (10). The pad (16) is provided as an underlayment of the cookware. The pad (16) is made of a heat resistant material. The temperature detection device comprises at least one SAW (surface acoustic wave) temperature sensor (18). The temperature detection device comprises at least one sensor antenna (20). The SAW temperature sensor (18) is electrically connected to the sensor antenna (20). The SAW temperature sensor (18) is embedded inside the pad (16). The sensor antenna (20) is embedded inside the pad (16) or arranged in a casing (24) above the pad (16).
