The invention discloses a flue gas turbine. The flue gas turbine comprises a main controller, a motor control unit, a fan system and a motor information acquisition unit, wherein the motor control unit comprises an air flow control subunit and a frequency conversion control subunit; the fan system comprises a motor; the air flow control subunit compares the target torque current and the actual torque current of the motor, and the frequency conversion control subunit changes rotating voltage according to a comparison result, so that the actual torque current and the target torque current of themotor are equal. Besides, the invention also discloses an air flow regulating method of the flue gas turbine. The flue gas turbine and the air flow regulating method thereof have the advantages thatthe air flow control subunit compares the sizes of the target torque current and the actual torque current of the motor, and the frequency conversion control subunit changes the rotating voltage according to the comparison result to regulate the actual torque current of the motor, so that rotating speed of the motor is regulated, the flue gas turbine keeps constant air flow output of a corresponding gear, and automatic air flow regulation is realized.
Description
technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood and a method for adjusting the air volume of the range range. Background technique [0002] In the related art, the blockage of the air channel of the range hood will increase the wind pressure and reduce the exhaust air volume, resulting in poor effect of exhausting the oil fume. At present, the fan of the range hood cannot automatically adjust the air volume under the premise of satisfying the air volume. Contents of the invention [0003] Embodiments of the present invention provide a hood and a method for adjusting air volume of the hood. [0004] The cigarette machine in the embodiment of the present invention includes a main controller, a motor control unit, a fan system, and a motor information collection unit; [0005] The main controller is used to send a gear position control command, and the gear position control command includes the target torque cur...
