Embodiment 1
[0035] An embodiment of the present invention provides a method for controlling a range hood.
[0036] The control method of the range hood is applied to the range hood. Wherein, the range hood includes a smoke guide plate and an action mechanism for controlling the movement of the smoke guide plate. In addition to the function of guiding and collecting smoke, the smoke deflector also has the function of condensing oil fume and separating grease. The action mechanism usually includes a motor and a transmission mechanism arranged between the motor and the smoke deflector. The common transmission mechanism can choose gear mechanism, pull rod mechanism and so on. It is finally determined according to the structure of the range hood. The forward rotation of the motor can drive the smoke guide plate to move forward to close through the transmission mechanism, and the reverse rotation of the motor can drive the smoke guide plate to move backward to open.

Embodiment 2
[0051] An embodiment of the present invention also provides a control device for a range hood, including:
[0052] The detection module is used to detect whether there is an abnormal sound signal during the closing process of the smoke deflector of the range hood;
[0053] The execution module is used to control the reverse movement of the smoke guide plate relative to the closing movement.
Embodiment 3
[0055] The embodiment of the present invention also provides a control device for a range hood, including a controller and a sound sensor.
[0056]In this embodiment, the controller is used to implement the control method in Embodiment 1. The controller includes one or more processors 11 and memory 12, figure 2 A processor 11 is taken as an example.
[0057] The controller may also include: an input device 13 and an output device 14 .
[0058] Processor 11, memory 12, input device 13 and output device 14 can be connected by bus or other ways, figure 2 Take connection via bus as an example.
[0059] The processor 11 may be a central processing unit (Central Processing Unit, CPU). The processor 11 can also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application-specific integrated circuits (Application Specific Integrated Circuit, ASIC), field programmable gate array (Field-Programmable Gate Array, FPGA) or other programm...
