Abstract
The present invention provides a method for monitoring the use of a cooking hob, including but not limited to: (a) obtention of multiple infrared images of the cooking hob; (b) multiple identification of individual cooking areas; (c) providing one or more predetermined responses where that cooking area deviates from its relevant criteria, such as setup temperature; (d) providing one or more predetermined responses associated to the hood based on the IR input; (e) further thermographic analysis to diagnose any deviation from its relevant criteria, such as reduction of any fire risk conditions, such as dry pot detection, (f) user presence detection, (g) lid on pan detection, and (h) energy consumption optimization.
The IR camera is placed onto an adjustable frame that allows us to change relative position (and angle) to the hob, with the aim of monitoring all the cooking surface on a wide variety of different combinations between hob and hood. Even for a specific hob model, the orientation may need some adjustment depending on the Hob-to-hood distance, which can’t be limiting for the consumer.
We consider two main scenarios. The first scenario is called stand-alone hood, where the smart hood is combined with any hob model from any manufacturer, regardless the layout and technology (induction, gas or mix). In this case the hood works only monitoring all the temperatures on the hood, so no closed-loop control between hob and hood is possible.
The second scenario includes both hood and hob that can communicate each other and react based on the IR sensor input. In this case it’s not only possible to monitor the temperature of each cooking zone but also to keep them all under control by closing the loop between the hob and the hood.
