Abstract (en)
[origin: WO0066950A1] Known cooker hoods may be controlled by a combination of sensors, such as for humidity and temperature, and commence increased action when thresholds are exceeded. Some sensors may be sensitive to particular compounds in gas form. Such combinations only react to a very specific range of chemical substances and are sensitive to contamination. According to one embodiment of the invention three sensors are used, the first sensor being sensitive to water vapour but not sensitive to grease and fat vapours, the second sensor being sensitive to both water vapour and to fat vapour, with opposing reactions, and the third having a high sensitivity to fat vapours, and a low sensitivity to water vapour. The sensors are all mounted above the grease filter and below the fan impeller.
