Description

Technical Field

[0001] The utility model relates to the field of oven temperature detection, in particular to a temperature detection device in an oven. Background Art

[0002] Oven temperature detection refers to the process of monitoring and adjusting the temperature inside the oven. Accurate and reliable control of the temperature inside the oven is crucial to the cooking and baking process, because different foods need to be cooked at specific temperatures. Too high or too low a temperature may cause the food to be burnt or undercooked. The temperature inside the oven is high, and the temperature sensor is easily damaged in a high temperature environment for a long time, resulting in errors in the data. In addition, the electromagnetic and high temperature environment in the oven will interfere with the signal line transmission, resulting in errors in the signal transmitted by the temperature sensor, resulting in inaccurate temperature data and affecting food processing.

[0012] The utility model provides a temperature detection device in an oven. An electric push rod is started by pressing a button to drive the temperature sensor to contact with a conduction head. The temperature sensor is closely contacted with the conduction head through the elastic force of a spring arranged between the temperature sensor and a slot block. The conduction head transmits the temperature in the oven to the temperature sensor for high temperature detection. The detected data is transmitted through a signal line. At the same time, a protection tube and an insulating shell insulate and heat-insulate the signal line to prevent signal interference. The signal line transmits the data to a display screen for display, thereby solving the problem that the temperature sensor is easily damaged in a high-temperature environment for a long time, resulting in data errors.
