Block is made of liquid crystal display and button.As shown in Figure 5 and Figure 6, using such structure setting, speed adjusting module passes through
TGS2600 oil smoke sensing monitoring oil smoke concentration in real time, and the data detected are converted into electric signal to be sent to STC89C52 mono-
Piece machine is handled, and is adjusted by the intelligence of DC motor speed, and then regulate and control kitchen ventilator and 2 wind speed size of air curtain component,
The man-machine mutual module of effect can realize that operating mode switches, and working condition is arranged with the function of the display of relevant parameter, to meet user
Individual demand.In addition, button has power supply and the wind speed regulating switch under automatic mode switch and manual mode, Yong Huke
By power supply by key control kitchen ventilator and its operating mode is adjusted, since kitchen ventilator currently on the market largely all only has
Three wind-speed gears, in order to meet the operating habit of user, the initial pattern of this item purpose is manual mode, and user can pass through wind speed
Regulating switch adjusts the size of wind speed, if user selects automatic mode, wind speed that can automatically adjust, liquid crystal display screen display oil
Smoke machine working condition is arranged and relevant parameter, guides user's operation.
It is learnt through experimental data, when low or first gear works, can exclude rate of release is now common smoke exhaust ventilator
0.7m/s oil smoke below；Top gear can exclude the oil smoke that rate of release is 1.0m/s, mean operating power 200W when working.
And certain wind speed is provided about in smoke exhaust ventilator petticoat pipe using air curtain, the wind speed of 3m/s, the discharge of enough flue gases can be reached.
