Abstract
A temperature control system for appliances, such as an electric grill, air fryer, vacuum blender, convection oven, induction cooker (e.g., wok), coffeemaker, etc. The control system comprises digital circuitry for controlling temperature of the appliance, and includes a first safety component in the circuitry for stopping the heating function at a threshold parameter, such as a maximum temperature, and a second safety component in the circuitry for stopping the heating function at a second threshold temperature if the first safety component fails at the first threshold temperature. The first and second safety components, preferably switches or fuses, are connected in series to establish a redundant safety mechanism.
