Ultrathin range hood and control method and control device thereof

The invention discloses an ultrathin range hood and a control method and device thereof. The ultrathin range hood comprises an oil smoke sensor, a central micro control unit (MCU) and a smoke exhaust unit, wherein the oil smoke sensor is used for acquiring an oil smoke signal in an environment where the ultrathin range hood is located and sending the oil smoke signal to the central MCU; the central MCU is used for determining a cooking scene identified by the oil smoke sensor according to the oil smoke signal and controlling the smoke exhaust unit according to the cooking scene identified by the oil smoke sensor; wherein the cooking scenes comprise a non-oil-smoke scene, a low-oil-smoke scene and a high-oil-smoke scene. According to the embodiment of the invention, the cooking scene can be automatically identified, and smoke discharge control is performed according to the cooking scene, so that energy waste can be reduced and working efficiency is improved. 本申请公开了一种超薄油烟机及其控制方法和控制装置；其中，该超薄油烟机包括：油烟传感器、中央微控制单元MC
