Sensor is sequentially electrically connects, and the ignition module, flame detection modules electrically connect with the control module respectively, its IGNITION CONTROL
Method comprises the following steps：
Step 1: control module setting igniting duration and being sent to blower fan drive module and starting blower fan signal and to igniting
Module sends ignition signal；
Step 2: control module samples combustion chamber apoplexy pressure difference K sizes by blast sampling module, wind pressure sensor；
Step 3: control module calculates the controlled quentity controlled variable P, P=of the proportioning valve drive module corresponding to gas proportion valve opening
(K-K0) the minimum blast difference needed when * A+P0, wherein K0 are the igniting of setting in combustion chamber, A are that the direct proportion of setting is normal
Number, P0 are the gas ratio valve minimum ignition controlled quentity controlled variable of setting；
Step 4: control module sends control signal by the controlled quentity controlled variable P comparative example valve drive modules calculated, so as to pass through
Proportioning valve drive module controls the aperture of gas ratio valve；
Step 5: control module detects whether to light a fire successfully by flame detection modules, igniting is exited when lighting a fire successfully
Flow, when unsuccessful and duration of lighting a fire of lighting a fire is covered, igniting flow is exited, it is unsuccessful and duration of lighting a fire is not covered when lighting a fire
When, return to step two.
A kind of ignition control method of the gas constant-temp. water heater with wind pressure sensor as described above, the control module
On be also associated with auditory tone cues module, in step 3, as K-K0 ＜ 0, control module judges that blower fan does not work, control mould
Block sends auditory tone cues by auditory tone cues module, is then log out flow of lighting a fire.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the ignition control method of this case gas constant-temp. water heater is adjusted by measuring the blast difference of wind pressure sensor
The aperture of proportioning valve, and in a bit of time that blower fan starts, combustion chamber apoplexy pressure difference K gradually increases, in this way, P=(K-
K0) * A+P0 can realize the control of the flow of combustion gas from small to large so that the combustion gas and AIR Proportional value stabilization in combustion chamber are suitable
In the scope of chalaza fire, so as to improve the success rate of igniting.
2nd, as K-K0 ＜ 0, control module judges that blower fan does not work, and control module sends sound by auditory tone cues module
Sound is prompted, and flow of lighting a fire is then log out, to realize controling mechanism.
[brief description of the drawings]
Fig. 1 is the structured flowchart of this case.
Fig. 2 is the control flow sketch of this case.
[embodiment]
Feature of present invention and other correlated characteristics are described in further detail by the following examples, in order to the same industry
The understanding of technical staff：
