Abstract
The utility model discloses a deflagration-proof gas water heater with step control, which comprises a controller, a combustor and a spraying nozzle for supplying fuel gas to the combustor, wherein the combustor comprises an ignition combustor and a main combustor. An electromagnetic valve I for controlling a fuel gas passage of the ignition combustor and an electromagnetic valve II for controlling a fuel gas passage of the main combustor are arranged on a fuel gas passage, and a fire needle and a sensing needle are arranged bedside the ignition combustor and are respectively electrically connected with the electromagnetic valve I and the electromagnetic valve II through the controller. The controller controls the two electromagnetic valves on the fuel gas passage through step control, so that a switch only needs to be switched on once and the water heater can automatically carry out step ignition. Under the condition that the ignition combustor doesn't ignite fuel gas in time, the time of fuel gas in a combustion chamber to reach the explosion limit is extended. The problem of deflagration caused by low ignition timely degree and ignition successful rate is relieved, and simultaneously, the utility model has the advantages of simple structure and operating program and is adapted to the requirements of consumers.
Description
Technical field
The utility model relates to a kind of domestic gas-fired water heater, particularly a kind of anti-burst-burning gas water-heater of the time stage control of lighting a fire.
Technical background
One of reason that causes detonation during the gas heater igniting is that whole combustion chamber gas concentration has reached explosion limit before point catches fire.The sparking mode of gas heater mainly contains two kinds at present, a kind of is to adopt the direct-fire on main burner of current control impuls igniter, it is simple to operate, but the igniting of burner igniting device is in time spent and success rate is lower, main burner sprays a large amount of combustion gas, cause the combustion gas discharge rate of burner more just to be lighted a fire successfully easily, form detonation.Another is to adopt pulse to light small fire burner earlier, utilizes small fire burner to light main burner again, and still, its operation sequence is many, and complex structure need be lighted small fire burner earlier, just can open water valve then, lights main burner by small fire burner.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of anti-burst-burning gas water-heater of simple in structure, easy to operate, grading control is provided.Particularly, when simplifying procedures, reduce the chance of detonation greatly at second kind of above-mentioned situation.
The anti-burst-burning gas water-heater technical scheme of the utility model grading control is: a kind of anti-burst-burning gas water-heater of grading control, comprise controller, burner and supply with the nozzle of combustion gas for burner, it is characterized in that: described burner comprises start-up burner and main burner, blast tube is provided with the electromagnetic valve I of control point ignition combustor fuel gas path and the electromagnetic valve II of control main burner fuel gas path, other igniting pin and the inductive needle of being provided with of start-up burner, described igniting pin and inductive needle are electrically connected with electromagnetic valve I and electromagnetic valve II respectively by controller.
The key of this scheme is, with two blast tubes of two magnetic valve grading control.During igniting, electromagnetic valve I is opened, controller passes through firing circuit simultaneously, the output firing pulse makes the igniting pin produce the discharge spark igniting, and behind the firing point ignition combustor, inductive needle is sensed flame, detection signal is delivered to controller by sensor circuit, controller is according to receiving signal, and opens solenoid valve II utilizes start-up burner to light main burner more automatically.
Described main burner fuel gas path end is provided with two or more nozzles, and described nozzle quantity is corresponding with the fire row quantity of main burner.
The beneficial effects of the utility model are, two magnetic valves on the controller grading control blast tube, like this, the only operation that need once open switch, water heater just carries out multistep ignition automatically, under the situation that start-up burner does not in time catch fire, combustion gas in the combustion chamber reaches the time elongation of explosion limit, when alleviating igniting and causing the detonation problem when in time degree and success rate are hanged down, the program that simplifies the structure and operate adapts to consumer demand more.
Description of drawings
Be further described below in conjunction with the anti-burst-burning gas water-heater of the drawings and specific embodiments the utility model grading control:
Accompanying drawing 1 is the anti-burst-burning gas water-heater part-structure schematic diagram of the utility model grading control;
Accompanying drawing 2 is the control block diagram of Fig. 1.
Among the figure: 1, electromagnetic valve I, 2, electromagnetic valve II, 3, controller, 4, nozzle, 5, fuel gas inlet, 6, start-up burner, 7 main burners, 8, the igniting pin, 9, inductive needle, 10, fire row.
The specific embodiment
Shown in accompanying drawing 1,2, the anti-burst-burning gas water-heater of the utility model grading control, its burner comprise start-up burner 6 and main burner 7, and main burner 7 is made up of two fire rows 10.Gas control valve comprises magnetic valve 1 that is located at ignition combustor 6 fuel gas paths in control point on the blast tube and the magnetic valve 2 of controlling main burner 7 fuel gas paths, start-up burner 6 other igniting pin 8 and the inductive needles 9 of being provided with, igniting pin 8 is electrically connected with magnetic valve 1 via controller 3 by firing circuit, and inductive needle 9 is electrically connected with magnetic valve 2 via controller 3 by sensor circuit.The start-up burner fuel gas path end that magnetic valve 1 is controlled is provided with nozzle 4, and the main burner fuel gas path end that magnetic valve 2 is controlled is arranged with two nozzles 4, and these two nozzles 4 are arranged 10 corresponding with the fire of two main burners 7 respectively.
Its combustion control device comprises two grading control loops, and first control loop is by the burning of magnetic valve 1, controller 3, firing circuit, igniting pin 8 common control ignition combustors 6.Second control loop is after inductive needle 9 is sensed the burning of start-up burner 6, gives controller 3 via sensor circuit output control signal, and controller 3 starts magnetic valve 2, lights main burner 9 under the effect of start-up burner 6.Specifically, magnetic valve 1 is opened during igniting, and combustion gas is by fuel gas inlet 5, through magnetic valve 1 and nozzle 4 point of arrival ignition combustors 6; Controller 3 is by firing circuit, and the output firing pulse makes igniting pin 8 produce discharge spark igniting, firing point ignition combustor 6.Behind the firing point ignition combustor 6, inductive needle 9 is sensed flame, and detection signal is delivered to controller 3 by sensor circuit, and controller 3 is according to receiving signal, and opens solenoid valve 2 utilizes start-up burner 6 to light main burner 7 more automatically.
