2, system open-close on-off 11 and sensing element are all connected, as shown in Figure 1 with control chip 3 circuit.Control chip 3 is for passing through
Sensing element judge gas valve keying and control ignition electrode 21 kindling material is carried out igniting compensate chip.
On-off circuit 1 and control chip 3 are connected with the outfan of rectification circuit 4, and the input of rectification circuit 4 connects to be had
AC220V voltage.
Gas valve is manual main air valve 12, as shown in Fig. 6 to Figure 12.Manual main air valve 12 includes valve body 121 and handle
122, the part side that handle 122 is connected with valve body 121 is provided with flange 123, and flange 123 can rotate with handle 122.Sensing unit
Part is magnetic induction switch or position sensor or optical sensor.In the present embodiment, sensing element is magnetic induction switch, and it includes phase
Adaptive Magnet 124 and magnetic induction part 125, magnetic induction part 125 is Hall element Q5, magnetic induction part 125 and control core
Sheet 3 connects.Magnet 124 is fixed on flange 123, can rotate with handle 122；Magnetic induction part 125 is fixed on valve body 121.
By turning handle 122, get final product band moving magnet 124 closer or far from magnetic induction part 125.
In the present embodiment, turning handle 122, make valve body 121 open, as shown in Figure 10 to Figure 12, now Magnet 124 away from
Magnetic induction part 125, magnetic induction part 125 does not produce the signal of telecommunication, and control chip 3 judges that valve body 121 is in opening；Turn
Fixed handle 122, makes valve body 121 close, and as shown in Figure 7 to 9, now Magnet 124 is near the side to magnetic induction part 125,
Magnetic induction part 125 produces the signal of telecommunication and sends control chip 3 to, and control chip 3 judges that valve body 121 is closed.
System open-close on-off 11 can be to use magnetic induction part or position sensor or the inductive switch of optical sensor,
It can by the one in button or rotary handle or plectrum or wherein combination in any mode control.System in the present embodiment opens
11 use magnetic induction parts are closed in make and break, specifically include Hall switch Q3.System open-close on-off 11 is operated by button-pressing way,
Its keying that can be used for controlling electromagnetic valve 5.Hall switch Q3 is connected with control chip 3.
Magnetic induction part is realized by magnetic induction principle, is not readily susceptible in stove environment when circuit is controlled by it
Liquid and the impact of greasy dirt, it is possible to ensure the normal operation of switch.
The ignition control method that commercial bakeware band kindling material compensates comprises the following steps:
1) system start-up step: press the button in system open-close on-off 11, sends enabling signal to control chip 3, makes
Control chip powers on, and electromagnetic valve 5 is opened；
2) kindling material lighting up procedure: when by magnetic induction part 125, control chip 3 senses that manual main air valve 12 is in closedown
State, then control ignition electrode 21 and enter long fired state, and kindling material is ignited；Combustion gas is supplied also to kindling material by kindling material air supply pipe 6
Ignited pin 21 is lighted, ignition electrode 21 constant ignition, to maintain kindling material not extinguish；
3) opening main fire step: open manual main air valve 12, combustion gas is delivered to burner by main fire air supply pipe 7, connects with kindling material
Main fire is fired in contact；By magnetic induction part 125, control chip 3 senses that manual main air valve 12 is opened, make to be in fired state
Ignition electrode postpones to close for 3 seconds, and this igniting of 3 seconds is to maintain the kindling material will not be because of combustion gas air pressure or the change of flow and moment master
Fire combustion disturbance and extinguish, after ignition electrode 21 is closed, mutually maintain fired state by main fire and kindling material；
4) main fire step is closed: closing manual main air valve 12, control chip 3 senses that manual main air valve 12 is in closedown shape
State, controls ignition electrode 21 and initially enters long fired state, allows kindling material keep burning, to maintain kindling material not extinguish, is now ready for
It is again introduced into main fire lighting up procedure；
5) system closes step: again press the button in system open-close on-off 11, sends to control chip 3 and closes letter
Number, making control chip 3 power-off, electromagnetic valve 5 cuts out.
During kindling material igniting, opening main fire and close main fire, due to gas flow change, air pressure changes or oxygen supply is unstable
The problem that kindling material is unstable or flame-out, the existing benefit being carried out kindling material by long igniting and delayed firing are easily occurred when Ding
Repay igniting, to ensure that kindling material will not stop working during these three, thus avoid repeatedly lighting a fire, improve work efficiency and safety
Performance.Use control chip 3, thus the control to compensating the duration of ignition is more accurate.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in enforcement disclosed above
Example, and amendment, the equivalent combinations that the various essence according to the present invention is carried out should be contained.
