Embodiment 3

[0091] Figure 4 The flow chart of Embodiment 3 of the range hood control method provided in the present application. exist Figure 4 In the illustrated embodiment, the current control state is a constant air volume control state, and the target control state is a constant torque control state. like Figure 4 As shown, the method of this embodiment includes:

[0092] S301. In response to the need to switch between the constant torque control state and the constant air volume control state of the range hood, keep the speed control signals of the constant torque control state and the constant air volume control state consistent.

[0093] S302: Acquire an air volume value corresponding to the constant air volume control state.

[0094] A possible implementation method can be obtained by detecting the current input current and speed of the motor of the range hood; and obtaining the current input current and speed of the motor according to the preset relationship list between c...

Abstract

The invention provides a range hood control method and device, a readable storage medium and a range hood. The method comprises the steps: 1, switching different control states responding to the rangehood, and maintaining the consistency of rotating speed control signals of different control states; 2, acquiring a control signal corresponding to a target control state to be switched according toa state parameter corresponding to the current control state and the rotating speed control signal; and 3, controlling the range hood to be switched to the target control state according to the control signal corresponding to the target control state. According to the control method, when the range hood needs to be switched between the different control states, the speed outer loop closed-loop control is switched in firstly, and the rotating speed of a motor of the range hood before and after switching is kept unchanged, so that the soft switching between the two different control states is achieved, and shaking caused by sudden change of the rotating speed of the motor in the switching process of the different control states is avoided.

Description

technical field [0001] The embodiments of the present application belong to the technical field of smart home appliances, and in particular relate to a range hood control method, a device, a readable storage medium, and a range hood. Background technique [0002] The cooker hood is an indispensable kitchen appliance for purifying the kitchen environment. The cooker hood purifies the kitchen environment by quickly pumping and discharging the harmful gases in the kitchen. At present, range hoods generally use constant torque control and constant air volume control. Among them, the constant torque control mode is a control mode that keeps the current input to the motor unchanged, and the constant air volume control mode is to maintain the exhaust air of the range hood. A control method that does not change the size of the amount. [0003] In the traditional method, the constant torque control method and the constant air volume control method usually use double closed-loop cont...
