  • Patent number: 8893709
    Abstract: The present invention provides a kitchen ventilation hood for ventilating the area above a cooking area and for exhausting air containing cooking by-products from a cooking station to an external environment through an exhaust duct while using a reduced airflow. The kitchen ventilation hood of the present invention is designed to minimize the required airflow through the hood in order to thoroughly evacuate the cooking by-products. The kitchen ventilation hood of the current invention has a structure incorporating an arched interior hood surface that directs the air to be ventilated through the air intake gap and the grease filter. The more efficient airflow resulting from the arched interior hood surface allows for removal of cooking by-products with a lower airflow than that required by currently available ventilation hoods. As such, the kitchen ventilation hood of the present invention represents a significant improvement over prior ventilation hoods.
