Automatic-cleaning extractor hood and control method thereof

The invention discloses an automatic-cleaning extractor hood. The automatic-cleaning extractor hood is mainly characterized by comprising a cleaning device, a controller and an air pressure detecting device, wherein the cleaning device and the air pressure detecting device are connected with the controller; the air pressure detecting device is used for detecting air pressure in an air cabinet of the extractor hood; and the controller is used for obtaining air pressure parameters of the air pressure detecting device, and controlling the cleaning device to start when the air pressure parameters are greater than or equal to a preset reference value. The control method for the automatic-cleaning extractor hood is characterized by comprising the following steps: a step that the air pressure detecting device detects an air pressure value in the air cabinet in real time, a step that a controller obtains the air pressure value detected by the air pressure detecting device, and the like. The automatic-cleaning extractor hood can accurately detect whether an oil screen of the extractor hood is blocked or not, and can automatically start the automatic cleaning function of the extractor hood when the oil screen is blocked, does not need a user to manually operate, and is convenient in use.
