Anti-lampblack-escape range hood and control method thereof

Abstract

The invention discloses an anti-lampblack-escape range hood. The anti-lampblack-escape range hood comprises a body (7), wherein an air duct system and a controller are arranged in the body (7); a fan is arranged in the air duct system; and the fan is electrically connected with the controller. The anti-lampblack-escape range hood is characterized in that a lampblack-escape detection device is arranged on the sidewall of the body (7); and the lampblack-escape detection device is electrically connected with the controller. The anti-lampblack-escape range hood is capable of detecting escaping lampblack, and capable of automatically switching over gears according to the detected signal to enhance the running air pressure and suction force of the range hood, thus a lampblack-escape phenomenon is eliminated.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, and more specifically relates to a range hood for preventing runaway smoke and a control method thereof.
