Abstract
The invention relates to a water heater, in particular to a method for controlling a draught fan of a cold vibration prevention gas water heater. The rotating speed of the draught fan is controlled by adopting a proportion integration differentiation (PID) algorithm; a whole starting process is divided into three sections; the first section is a pre-sweeping stage before ignition for sweeping and exhausting by six times of a PID parameter; the second section is ignition service for igniting by two times of the PID parameter; and the third section is a preheating stage for preheating by a half of the PID parameter and getting into normal PID constant-temperature control after a preheating time. By the method, cold vibration can be reduced effectively, the working noise of the water heater can be lowered and the service life of the product is prolonged.
Description
Technical field
The utility model relates to the method for heating and controlling of a kind of gas heater, particularly a kind of constant temp gas water heater.
Background technology
Gas heater is a kind of water heater that utilizes combustion gas to heat non-storage-type, and its principle is to allow flow of hot water cross flame, in real time heating.In recent years, the constant-temperature hot water device occurs, met the requirement of the higher quality of life of people.Early stage constant-temperature hot water device, the method for taking are to regulate hot and cold water, this thermostatic control method temperature adjustment inaccuracy; So present constant-temperature hot water device all is to have adopted air door control realization, that is to say by the control to the combustion chamber blower fan, regulates combustion power, reaches the purpose of constant temperature, general adjustment control method is to use PID control.PID control is meant the control method of proportion of utilization, differential, integration, and present prior art is a constant PID control method from start to finish, and the output actual parameter of PID was not handled.
Because the rate of heat addition of constant-temperature hot water device has certain requirement, promptly need in short time, be heated to design temperature rapidly.In this time, the temperature difference of heating part is not bigger can to cause heating part and other, because the relation of expanding with heat and contract with cold, the degree of the expanding with heat and contract with cold difference of each parts, whole water heater can resonate along with the high velocity air of combustion chamber, causes very big noise, and this phenomenon is called cold shaking.When this in the winter time environment temperature was low, the cold phenomenon of shaking was particularly serious.
Summary of the invention
The present invention is exactly in order to overcome the shortcoming of the described existing general PID control blower fan of background technology, to invent a kind of blower control method that can alleviate the cold phenomenon of shaking.
For reaching the foregoing invention purpose, blower control method of the present invention, still adopt pid algorithm control rotation speed of fan, whole ignition trigger process is divided into three sections, it at first is prefiring preceding cleaning stage, cleaning air draft with big pid parameter, is ignition phase then, serves as the igniting service with bigger pid parameter; The 3rd is to preheat the stage, preheats with less pid parameter, enters the normal PID thermostatic control after preheating the time through one.
The time that preferably preheats is 20 seconds, and this time period has been taken into account rate of warming and pre-windproof shaking.
The present invention is according to the temperature difference, with front and back a period of time of whole igniting, cooperate after concrete the division and arrange more suitable fan speed, the final combustion power of realizing that output is different, allow heating process that a variation is arranged, not only do not influence firing rate and precision, and heating is mild, can effectively reduce the cold phenomenon of shaking.Reduce the operating noise of water heater, also prolonged the service life of product to a certain extent.
Description of drawings
Fig. 1, the flow chart of embodiments of the invention.
The specific embodiment
Fig. 1 is one embodiment of the present of invention.
After the blower fan control beginning, what at first carry out is preceding cleaning, and corresponding requires fan speed than very fast, and the residual exhaust gases in the pipeline is discharged, and the pid parameter of getting 6 times here carries out preceding cleaning; Begin igniting after cleaning is finished, in the time of igniting,, set 2 times pid parameter air quantity and serve igniting in order to prevent detonation; After lighting a fire successfully is to preheat the stage, and operation principle of the present invention is exactly the time period that the segmentation igniting takes fire, after igniting is finished, because this moment is when being exactly temperature difference maximum, so to the heating starting stage, the pid parameter of employing 1/2 preheats, and preheats time set 20 seconds.By the human intervention pid parameter, take heating means comparatively slowly, to reduce cold shaking.
After 20 seconds preheat finished, just enter in the normal PID heated at constant temperature control program.
Claims (3)
1. one kind prevents the cold gas heater blower control method that shakes, what adopt is pid algorithm control rotation speed of fan, it is characterized in that: whole starting process is divided into three sections, it at first is prefiring preceding cleaning stage, clean air draft with big pid parameter, being ignition phase then, serves as the igniting service with bigger pid parameter; The 3rd is to preheat the stage, preheats with less pid parameter, enters the normal PID thermostatic control after preheating the time through one.
2. a kind of cold gas heater blower control method that shakes that prevents according to claim 1 is characterized in that: described to preheat the time be 20 seconds.
3. a kind of cold gas heater blower control method that shakes that prevents according to claim 1 is characterized in that: the big pid parameter of cleaning is 6 times of pid parameters before described; Big pid parameter is meant 2 times of pid parameters; Less pid parameter is meant 1/2 times of pid parameter.
