Abstract
A low depth telescoping downdraft ventilator controlled by an electronic controller providing a precisely controlled and efficient way of removing gases and fumes is disclosed. The low depth telescoping downdraft ventilator has the ability to fit behind a built-in oven placed below a cook top unit. The telescoping downdraft ventilator has an almost infinitely selectable range of heights above a cook top with a built in oven. The ventilator collects and draws in exhaust fumes and smoke, filters it and re-circulates or expels it either outdoors or indoors. The inner member of the telescoping ventilator may house the exhaust fans and may move up or down without the use of mechanical switches for elevation detection and stopping. The ventilator may have sensors to detect temperatures, filter change need, fan speeds, telescoping stop points, energy consumption, resistance and voltage, enabling programmable set point operation.
