Abstract

The invention discloses an extractor hood with a fume run-away prevention function. The extractor hood comprises a machine body (7), and an air channel system and a controller are arranged in the machine body (7). A draught fan is arranged in the air channel system and electrically connected with the controller. A fume run-away detection device and a cleaning device for cleaning away oil dirt on the fume run-away detection device are arranged on the side wall of the machine body (7). The fume run-away detection device and the cleaning device are both electrically connected with the controller. Running-away oil fumes can be detected through the fume run-away detection device of the extractor hood, gears can be automatically shifted according to detected signals so as to enhance the operating air pressure and suction force of the extractor hood, and the fume run-away phenomenon is eliminated accordingly.

Description

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