Embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings
The specific embodiment of the present invention is described in detail.
Reference picture 1, Fig. 1 is a kind of structural representation of range hood, and range hood includes：Air inlet 1
With can close the locking device 2 of air inlet 1.With reference to Fig. 2, the control method of range hood flame risk can
With including：Step S1 is performed, in culinary art and range hood operation, the flame risk of air inlet 1 is detected,
And flame risk signal is produced when detecting flame risk；Step S2 is performed, flame risk is being received
After signal, the control closing air inlet 1 of locking device 2.When being not detected by flame risk, locking device 2
It is maintained at the state for opening air inlet 1.
This control method proposes the new approaches of enhancing range hood fire prevention control.It is real in cooking process
When detection air inlet 1 whether there is flame risk.When range hood normal work, at locking device 2
In position A, air inlet 1 is opened, oil smoke is inhaled into air inlet 1.It is fiery when kitchen range catch fire in cooking process
Flame can scurry into air inlet 1, can now detect air inlet 1 and there is flame risk, locking device is controlled immediately
2 move to position B to air inlet 1, close air inlet 1.Locking device 2 can prevent propagation of flame to suction
