Noise control method and device of smoke exhaust ventilator, smoke exhaust ventilator and storage medium

Abstract

The invention discloses a noise control method and device of a smoke exhaust ventilator, the smoke exhaust ventilator and a storage medium. The noise control method of the range hood comprises the following steps: determining a target noise value of the range hood; acquiring the current power and the current rotating speed of a motor of the range hood; determining the current noise value of the range hood and the current blockage degree of a flue of the range hood according to the current power and the current rotating speed; determining whether the operation state of the motor needs to be adjusted according to the target noise value and the current noise value; and when the operation state of the motor needs to be adjusted, the operation state of the motor is adjusted based on the current blockage degree and the target noise value. According to the technical scheme, the problem that the range hood cannot adjust the running state of the motor in time according to the flue blocking degree is solved, and the effects that the running state of the motor is adjusted in time under the condition that the flue blocking degree is large or small, and stronger suction force is provided as much as possible under the condition that constant noise is kept are achieved.

Description

technical field [0001] The embodiment of the present invention relates to the performance optimization technology of a range hood, and in particular to a noise control method and device for a range hood, a range hood and a storage medium. Background technique [0002] As the residential floors get higher and higher, the number of users carried by the common range hood smoke exhaust pipe in the building is increasing. For users at different times or on different floors, the smoke exhaust resistance of the range hood is different. [0003] In the existing range hood, when the smoke exhaust duct is blocked or the pressure is high during the peak cooking period, the motor speed of the range hood will automatically increase, and the pressure in the exhaust duct is relatively high during the low peak cooking period. Hours, the range hood still maintains the previous motor speed, so there is a problem that the noise of the range hood increases significantly during the peak cooking ...

Problems solved by technology

[0003] In the existing range hood, when the smoke exhaust duct is blocked or the pressure is high during the peak cooking period, the motor speed of the range hood will automatically increase, and the pressure in the exhaust duct is relatively high during the low peak cooking period. Hours, the range hood still maintains the previous motor speed, so there is a problem that the noise of the range hood increases significantly during the peak cooking period and cannot provide stronger suction within the acceptable range of the noise value during the low peak cooking period, which brings troubles to the user
