Description
Technical field
The present invention relates to a kind of mechanical temperature adjustment gas heater, especially a kind of startup method of gas heater with electronic blower fan smoke evacuation.
Background technology
Present prior art, gas heater comprises blower fan, blast switch, magnetic valve, igniting pin and inductive needle etc.During use, in the time of must guaranteeing water heater working, can the flue gas behind the fuel gas buring be drained into outdoor, and excessive when extraneous wind-force, when flue gas can not effectively be discharged, water heater must quit work, and is safe in utilization to guarantee product.The existing structure forced-ventilated water heater of taking out by force mainly detects blower fan inner flow passage negative pressure through blast switch and solves above problem.Its basic principle is: when water heater was not worked, blower fan negative pressure mouth pressure was zero, the blast switch normally open; During the water heater operate as normal, blower fan negative pressure mouth pressure is a negative value, and blast switch is in the short circuit state; Water heater working and extraneous blast be excessive, in the time of can not effectively flue gas being discharged, blower fan negative pressure mouth pressure is for rising, blast switch is in off-state.
According to the existing structure forced-ventilated water heater working program of taking out by force, after water heater was opened, blower fan began to rotate, rotating speed improves gradually; After the blast switch action, water heater igniting pin begins discharge, after time-delay in more than half seconds; The water heater magnetic valve is opened, and after water heater is lighted a fire successfully, gets into normal operating conditions.
This working method has two drawbacks: the duration of ignition is long, behind the each boiling water of user, all will wait for about 5 seconds; Water heater could be lighted a fire, and cold day is longer the duration of ignition, during water heater to discharge a large amount of cold water; Waste a large amount of running water; And user health is had adverse effect, and especially winter, the running water temperature was lower, caused the user to suffer from cold, catch a cold easily; The blast switch operating pressure is extremely low, influences its reliability.
Summary of the invention
The objective of the invention is: a kind of control method of the mechanical temperature adjustment gas instantaneous water heater with the smoke evacuation of electronic blower fan is provided, and it can guarantee effectively that water heater starts fast, and operate as normal, guarantees that flue gas normally discharges.
The present invention is achieved in that a kind of control method of the mechanical temperature adjustment gas instantaneous water heater with the smoke evacuation of electronic blower fan, it is characterized in that: may further comprise the steps:
(1) opening power, water is through behind the aqueous vapor interstage valve, and microswitch is connected on the aqueous vapor interstage valve;
(2) igniting needle-discharging, the motor of blower fan rotates, and the Hall element that is arranged in the blower fan detects the motor speed of blower fan, as does not reach the speed of setting, after the time-delay, outage, blower fan stops operating;
(3) after rotation speed of fan reached the rotating speed of setting, magnetic valve was opened, and burner begins igniting, and is long like the duration of ignition, then closed electromagnetic valve;
(4) inductive needle detects flare up fire, as responding to less than flare up fire closed electromagnetic valve;
(5) blower fan is by setting rotary speed working, and water heater is accomplished and started;
(6) after the water heater operate as normal, Hall element detects rotation speed of fan, inductive needle induction flare up fire, and blast switch detects extraneous blast, and anti-dry protection temperature controller should be in normal operating conditions; If rotation speed of fan does not reach requirement, inductive needle is responded to less than flare up fire, and water heater gets into guard mode, closed electromagnetic valve, and blower fan stops operating after delaying time.
The control method of described a kind of mechanical temperature adjustment gas instantaneous water heater with the smoke evacuation of electronic blower fan; Its special character is: in the said step (3), at ignition phase, after rotation speed of fan reaches the fire speed minimum requirements; Blower fan keeps power supply, makes rotation speed of fan continue to rise; After rotation speed of fan surpassed peak fire rotating speed, blower fan was stopped power supply, and blower fan turns round under action of inertia, rotating speed continues to descend; After rotation speed of fan was lower than the fire speed minimum requirements, blower fan was supplied power once more, made rotation speed of fan continue to rise, so repeatedly.
A kind of control method of the mechanical temperature adjustment gas instantaneous water heater with the smoke evacuation of electronic blower fan, the influence with the external condition of not receiving guarantees normally to use, and can effectively flue gas be discharged to outdoor characteristics.
Description of drawings
Fig. 1 is a front view of the present invention.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
As shown in Figure 1; A kind of mechanical temperature adjustment gas instantaneous water heater with electronic blower fan smoke evacuation; Comprise aqueous vapor interstage valve 1, magnetic valve 2, microswitch 3, burner 4; Blower fan 6, controller 7, igniting pin 8, the inductive needle 9 of water tank 5, band rotation speed of fan test Hall element, blast switch 10 and anti-dry heating temperature controller 11.
Said water tank 5 comprises combustion chamber and the heat exchanger that is made up of water pipe;
A kind of control method of the mechanical temperature adjustment gas instantaneous water heater with the smoke evacuation of electronic blower fan, it may further comprise the steps:
(1) opening power, water are gone forward side by side through the aqueous vapor interstage valve behind the water tank, and microswitch is connected on the aqueous vapor interstage valve;
(2) igniting needle-discharging, the motor of blower fan rotates, and the Hall element that is arranged in the blower fan detects the motor speed of blower fan, as does not reach the speed of setting, after the time-delay, outage, blower fan stops operating;
(3) after the rotating speed of motor of blower fan reached the rotating speed of setting, magnetic valve was opened, and burner begins igniting, and is long like the duration of ignition, then closed electromagnetic valve;
(4) inductive needle detects flare up fire, as responding to less than flare up fire closed electromagnetic valve;
(5) motor fan is by setting rotary speed working, and water heater is accomplished and started;
(6) after the water heater operate as normal, Hall element detects rotation speed of fan, inductive needle induction flare up fire, and blast switch detects extraneous blast, and anti-dry protection temperature controller should be in normal operating conditions; If rotation speed of fan does not reach requirement, inductive needle is responded to less than flare up fire, and water heater gets into guard mode, closed electromagnetic valve, and blower fan stops operating after delaying time.
