KITCHEN VENTILATION SYSTEM

摘要

A ventilation system for a cooking area includes a hood having top, front and rear walls and adapted for mounting above the cooking area. A front chamber located in the hood adjacent the front wall has an upper section and a lower section. A rear chamber in the hood is located adjacent the rear wall and is adapted to remove smoke-laden air. Both the front and rear chambers extend horizontally from one side of the hood to the other side. A central region located between the front and rear chambers has an open bottom end and a top end closed by the top wall. Filter means are provided across the bottom of the rear chamber in order to clean the exhaust air. One or more registers are located in an inner wall dividing the upper section of the front chamber from the central region. One or more further registers are located in an inner wall dividing the lower section of the front chamber from the central region. These further registers permit make-up air to flow downwardly and inwardly from the front chamber into an open space between the hood and the cooking area. All of these registers have louvers or blades for adjusting the airflow therethrough. A sloping baffle is located along the bottom edge of the front wall of the rear chamber. Two elongate, opposed blade dampers extend from one side of the front chamber to the other. These dampers are positioned between the upper and lower sections.
