It is electrically connected with display.
The second solenoid valve 4 is arranged in the shell of gas-cooker 1, and the shell of gas-cooker 1 is arranged in the first solenoid valve 2
Outside, combustion gas probe 3 is arranged in the shell of gas-cooker 1 or outside shell.
A kind of operating method of the control system of intelligent safety gas range, comprising the following steps:
Step 1 is passed through the working time of 13 default setting gas-cooker of first timer, then by user by producer first
It is manually pressed by operating switch 8 to start, the wake-up beginning timing of first timer 13 of 6 output signal of pulser, first timer 13
Timing signal synchronization is exported to second timer 14, and following gas-cooker works normally until when working time countdown is zero；
Alternatively, passing through the working time of 13 default setting gas-cooker of first timer by producer first, then by user hand
Dynamic to press the starting of operating switch 8,6 output signal of pulser wakes up first timer 13 and starts timing, and following gas-cooker is normal
Work is until when working time countdown is zero.
In the present embodiment, since the above-mentioned working time is to pass through 13 default setting of first timer by producer first
, therefore be referred to as initially protecting the working time, its object is to improve the effect of protection gas-cooker.
Step 2,13 output instruction signal of first timer control the first solenoid valve 2 and second solenoid valve 4 to pulser 6
It closes respectively, first timer controls 13 control switch triode 12 of second timer and ends 0.1~2 second, at this point, relay
11 power loss, the normally opened contact of relay 11 return to normally-closed contact state, and 6 power loss of pulser resets, the first solenoid valve 2 and the second electricity

One solenoid valve 2 and second solenoid valve 4 are closed, and the second tunnel controls 14 control switch triode of second timer through first timer 13
12 cut-offs 0.1~2 second, 11 power loss of relay, the normally opened contact of relay 11 returns to normally-closed contact time, 6 power loss of pulser
It resets, power loss is again switched off respectively for the first solenoid valve 2 and second solenoid valve 4.
When gas-cooker operates normally at work, when there is accident extinguishing, the first via is by first electricity of the control of pulser 6
Magnet valve 2 and second solenoid valve 4 are closed respectively, and the second tunnel controls 14 control switch triode of second timer through first timer 13
12 cut-offs 0.1~2 second, 11 power loss of relay, the normally opened contact of relay 11 returns to normally-closed contact time, 6 power loss of pulser
It resets, power loss is again switched off respectively for the first solenoid valve 2 and second solenoid valve 4.
When combustion gas probe 3 detects gas leakage, 3 control pulser 6 of first via combustion gas probe at this time closes first
Solenoid valve 2 and second solenoid valve 4, the second tunnel at this time control 14 control switch triode of second timer through first timer 13
12 cut-offs 0.1~2 second, 11 power loss of relay, the normally opened contact of relay 11 returns to normally-closed contact time, 6 power loss of pulser
It resets, the first solenoid valve 2 and 4 power loss of second solenoid valve are again switched off.
When gas-cooker is without timing function and when combustion gas probe 3 detects gas leakage, 3 control pulser 6 of combustion gas probe
The first solenoid valve 2 and second solenoid valve 4 are closed respectively, meanwhile, combustion gas probe 3 directly controls switch triode 12 cut-off 0.1~2
Second, 11 power loss of relay, the normally opened contact of relay 11 returns to the normally-closed contact time, and 6 power loss of pulser resets, the first electromagnetism
Power loss turns off respectively for valve 2 and second solenoid valve 4.
When power failure, 11 power loss of relay, the normally opened contact of relay 11 returns to normally-closed contact state, and reserve battery 10 is automatic
Access.
The plus-minus of the operable time of time button 15 is adjusted, when operating between setting when increasing to maximum time,
First timer 13 is reset and output order controls to pulser 6 and closes the first solenoid valve 2 and second solenoid valve 4, the first timing
Device 13, which again exports timing signal synchronization, ends 0.1~2 second to 14 control switch triode 12 of second timer, relay 11
Power loss, the normally opened contact of relay 11 return to the normally-closed contact time, and 6 power loss of pulser resets, the first solenoid valve 2 and the second electromagnetism
4 power loss of valve is again switched off.The reason of operating in this way is: the increase adjusting key of working time is once out of control, and closing can keep away in advance
Exempt from initiation fire out of control.
In the present embodiment, this product can be preset: fire can be closed every time automatically after forty minutes by working normally after igniting,
Can also be by user's sets itself: 1 minute to 4 when after timed-shutoff fire.Also, the combustion gas of this product connection tracheae is cut not
Have gas leakage.In addition, it is in use in this product, once there is gas leakage, it will automatically cut off air inlet to ensure safety.
In the present embodiment, combustion gas includes natural gas and liquefied gas, artificial coal gas.First solenoid valve 2 and second solenoid valve 4
Normality be in off state.
