Embodiment 1

[0029] figure 1 It is a flow chart of a noise control method for a range hood provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where constant noise is maintained under the condition that the flue blockage degree of the range hood changes. The method can be composed of The noise control device of the range hood built in the range hood is implemented, specifically including the following steps:

[0030] S110. Determine the target noise value of the range hood.

[0031] The noise of range hoods usually changes with the degree of blockage of the flue. The blockage here not only refers to the blockage of the flue by oil or impurities in the flue, but also refers to the situation when multiple range hoods share one flue. The influence of smoke exhaust on each other. For example, during the peak season of cooking, residents of the same unit in a building share a flue, and a large amount of smoke and dust are discharged in a concentra...

Embodiment 2

[0054] figure 2 It is a flow chart of a noise control method for a range hood provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation of maintaining constant noise under the condition that the flue clogging degree of the range hood changes, and is a comparison of the embodiment Further refinement of one, the method can be implemented by the noise control device of the range hood built in the range hood, specifically including the following steps, wherein the steps that are the same as or similar to those in the first embodiment will not be repeated:

[0055] S210. Determine the target noise value of the range hood.

[0056] S220. Obtain the current power and current rotational speed of the motor of the range hood.

[0057] S230. Obtain noise relationship information of the range hood.

[0058] The noise relationship information of the range hood can be presented in the form of a table as in Embodiment 1, or can be abstracted into a ...

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 ...
