Range hood with novel control system and working method for system

The invention relates to a range hood with a novel control system and a working method for the system. The range hood comprises a housing and an exhaust system installed in the housing, the front end of the housing is provided with a panel of the control system, and the range hood is characterized in that the control system comprises two groups of inductive control systems and a manual control system; each inductive control system comprises an infrared inductive probe and an LED spotlight with indication effect; and the two groups of the inductive control systems are respectively installed at the left side of the range-hood housing as an illumination inductive control system of the range hood and at the right side of the range-hood housing as a wind-wheel rotating-speed inductive control system of the range hood. The beneficial effects comprise that by respectively installing the infrared inductive probes for controlling illumination and wind-wheel rotating speed at the two sides of the range hood, a user can realize control on corresponding functions by shaking arms past the inductive area during cooking, and the control process does not need contact with the range hood, so that the range hood is convenient to operate and easy to clean.
