A kind of ignition control device and method of cooking stove
Technical field
The invention belongs to commercial kitchen tool fields, and in particular to a kind of ignition control device and method of cooking stove.
Background technique
Commercial stove is widely used in the occasions such as restaurant, hotel, mostly liquefied gas combustion heat supplying, and liquefied gas needs to mix empty
It could full combustion after gas.Most conventional commercial stove generally includes gas inlet, kindling material control valve and main fiery control valve,
It is first turned on kindling material control valve, Chang Minghuo is lighted by fire rod, main fire control valve point is then opened and fires main fire, whole process
It needs to be manually operated.In order to keep sparking mode more convenient, later commercial stove uses igniter just to replace manual ignition
Stick, commercial stove also have added flame-out protection device, and can close gas inlet when burner fray-out of flame ensures combustion gas
Initiation safety problem will not be revealed.But simply using igniter and flame-out protection device only it is simple solve igniting and
The problem of blowout protection, can not control the flame combustion situation of entire cooking stove on the whole.When there is maloperation in cook, than
Flame is caused to be unable to normal combustion initiation gas leakage as unignited Chang Minghuo opens main fiery control valve;For example cooking stove is using
Midway flame extinguishes suddenly and does not prompt cook, also results in a large amount of gas leakages;Such as in use process combustion gas gas
It presses unstable or wind pressure unstable and cannot be understood in time by cook, cause general mood proportion unbalance and fuel gas buring is caused not fill
Point, exhaust emission rate is exceeded etc., these problems all easily cause security risk, can even jeopardize the person of user when serious
Safety.
