Cookery air purification and exhaust system

摘要

An air filtration and exhaust system is described. The system comprises a microcontroller, a power supply, and a series of sensors that detect the presence of airborne contaminants such as ultra fine particles, smoke, natural gas and radon gas. In the presence of these airborne contaminants, the system is designed to inactivate and prevent operation of nearby food preparation appliances. Once these contaminants have been safely removed, the operation of these appliances is restored. In addition, the ventilation system may be equipped with a purification subassembly, which safely and efficiently removes such containments from the area. The system may also comprise an alarm that is activatable in the presence of these contaminants.

1. A ventilation system, comprising:
a) a microcontroller electrically connectable to an electrical power supply; b) an impellor capable of variable speed operation electrically connectable to the microcontroller and the power supply; c) a sensor capable of emitting a measurable sensor signal electrically connectable to the microcontroller and the power supply; d) a filtration subassembly comprising a filter positioned within a filtration housing positionable adjacent the impellor; e) a stove shutoff mechanism activatable when a sensor threshold value is exceeded; f) an electrical outlet shutoff mechanism activatable when the sensor threshold value is exceeded; and g) wherein actuation of the stove shutoff mechanism and/or the electrical outlet shutoff mechanism occurs when the sensor signal has exceeded the sensor threshold value.
