Description
Technical field
The present invention relates to water heaters and wall-hung boiler technical field, and in particular to gas heater and the adaptive flue of wall-hung boiler
The control method of the adaptive flue pressure change of the ignition control method and wall-hung boiler of pressure change.
Background technique
Gas heater or wall-hung boiler have become the heating equipment of family's indispensability, are widely used.And with height
Layer house is more and more, and the gas heater or wall-hung boiler of family are typically mounted on living balcony, gas heater or wall hanging
Furnace is influenced by floor wind pressure also increasing in use.
Existing gas heater or wall-hung boiler Ignition Logic only one switching value compensate, therefore, outside without rotation speed of fan
Caused point non-ignitable fire when boundary's wind pressure is excessive, downdraught or flue block lights flame-out, ignition difficulties, ignition deflagrating of hot etc.
Problem causes user not to be available water heater or wall-hung boiler, reduces gas heater or wall-hung boiler adaptability.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide gas heaters and the adaptive flue pressure of wall-hung boiler
The ignition control method of variation is realized highly reliable according to flue blockage or the quick air blower of compensating revolving speed of extraneous wind pressure size
Ignition success rate.
In order to achieve the goal above, the technical solution adopted by the present invention is that:
The ignition control method of gas heater and the adaptive flue pressure change of wall-hung boiler, comprising the following steps:
S1. in the case where gas heater or wall-hung boiler are in ideal case, hot water tap is opened, starts blower, is obtained practical
Rotation speed of fan；
S2. judge the size relation of the practical rotation speed of fan and theoretical rotation speed of fan, the theoretical rotational speed of the blower is
Rotation speed of fan when the flue external pressure of the gas heater or wall-hung boiler is equal with flue internal pressure, the reality of the blower
Rotation speed of fan when border revolving speed is the flue external pressure and unequal flue internal pressure of the gas heater or wall-hung boiler；
S3. according to the judging result of step S2, the rotation speed of fan and igniting for adjusting the gas heater or wall-hung boiler are patrolled
Volume, run the gas heater or wall-hung boiler normal ignition.
When gas heater or wall-hung boiler before ignition when, if to be greater than flue internal pressure or flue stifled for flue external pressure
Plug, main controller real-time monitoring blower actual speed and within the scope of preset rotation speed, it is corresponding increase wind velocity gradient, adjustment igniting is patrolled
Volume, realize that normal ignition, machine work normally.Flue inside and outside pressure can be detected by pressure sensor, and signal analyzes and determines
It is completed with transmission instruction by main controller.
Further, the specific judgement of the step S3 and method of adjustment are as follows: because flue external pressure is greater than inside
Pressure or flue blockage may the problems such as efficiency of combustion is relatively low, midway is flame-out and flame is excessive, therefore in order to realize machine just
Often work, avoids the above risk, and rotation speed of fan and general mood proportion are done and be adaptively adjusted as follows:
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets actual measurement rotation speed of fan in 3100r/min and 3450r/
When between min, adjustment rotation speed of fan is 3500r/min or more, and readjusts and execute Ignition Logic I, and the Ignition Logic I is
Increase by 5% on the basis of mathematical point fire PWM value；
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets actual measurement rotation speed of fan in 3450r/min and 3750r/
When between min, adjustment rotation speed of fan is 3900r/min or more, and readjusts and execute Ignition Logic II, the Ignition Logic II
It is to increase by 10% on the basis of mathematical point fire PWM value；
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets actual measurement rotation speed of fan in 3750r/min and 3950r/
When between min, adjustment rotation speed of fan is 4100r/min or more, and readjusts and execute Ignition Logic III, the Ignition Logic
III be to increase by 15% on the basis of mathematical point fire PWM value.
Further, when outdoor boundary wind-force is excessive, when being temporarily not suitable for using the gas heater or wall-hung boiler,
When exactly practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan greater than 3950r/min, prompt cannot make
With the gas heater or wall-hung boiler.
Further, if the gas heater or wall-hung boiler are just when practical rotation speed of fan is less than theoretical rotation speed of fan
Often work indicates the unplugged state of flue.
Beneficial effects of the present invention:
Compared with prior art, method of the invention can needle gas heater or wall-hung boiler when in use, to extraneous wind pressure
Excessive, downdraught or flue caused point non-ignitable fire when blocking light the problems such as flame-out, ignition difficulties and ignition deflagrating of hot,
According to flue blockage or the quick air blower of compensating revolving speed of extraneous wind pressure size, realizes highly reliable ignition success rate, avoid high level
When user uses gas heater or wall-hung boiler, because of external wind buckling, gas heater or the non-ignitable fire of wall-hung boiler point, point are caused
The problem of firing flame-out, ignition difficulties and ignition deflagrating of hot improves it while improving gas heater or wall-hung boiler safety in utilization
Efficiency of combustion, it is energy saving, also save for user with gas cost.
