Abstract
The utility model discloses a domestic gas heater's ignition, including some firearm, high temperature wire, ripples fine pipe, the outsourcing of ripples fine pipe is outside the wire, the wire tie point firearm switch, its characterized in that: the fixing base is installed to some firearm lower extreme, it is fixed that fixing base and wire pass through the flange, is provided with the sealing washer at flange joint end, ignition installs the position that the top is higher than the fire row around the combustor, and the utility model who adopts above technical scheme has the influence that does not receive environmental factor, and no electromagnetic interference, long service life ignites more reliably, makes domestic gas instantaneous water heater's single ignition success rate reach 100%, uses safe and reliable's advantage more.
Description
[technical field]
The utility model relates to a kind of igniter, is a kind of igniter that is applied in the domestic gas-fired water heater on the domestic gas-fired water heater concretely.
[background technology]
What at present, existing domestic gas instantaneous water heater igniter was used is the high-frequency impulse spark ignition.The high-frequency impulse spark ignition is exactly to be installed in two electrodes on the burner of gas instantaneous water heater by certain distance, getting electric spark after the energising releases energy, make the flammable mixture of discharging from gas instantaneous water heater burner pod apertures run into electric spark and lighted, but energy shortage one milli that electric spark discharges is burnt, so just there is the problem of lighting a fire and than difficult point, that is to say the high-frequency impulse spark ignition poor reliability of not only lighting a fire, and form unsafe detonation easily, service time is long slightly, two electrode surfaces also are easy to form carbon distribution, and so just more difficult point.The noise pollution and the electromagnetic interference of high-frequency impulse igniting have been brought for the automatic thermostat circuit of water heater and surrounding enviroment and are seriously influenced.
[utility model content]
The purpose of this utility model provides a kind of no electromagnetic interference, long service life, the igniter of the domestic gas-fired water heater of safety and reliability.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of igniter of domestic gas-fired water heater, comprise igniter, high temperature wire, the fine pipe of ripple, outer the wrapping in outside the high temperature wire of the fine pipe of ripple, described lead connects ignition switch, and described igniter lower end is equipped with holder, and described holder and lead are fixed by flange, be provided with sealing ring at flanged ends, the top that described igniter is installed in around the burner is higher than the position that fire is arranged.
Described ignition switch is a relay.
Described ignition switch is a FET.
Described igniter is made up of silicon nitride and molybdenum disilicide material.
The fine pipe of described ripple is braided glass tube.
Adopt the utility model of above technical scheme, solved all drawbacks that spark ignition exists, adopt the full ceramic high temperature igniter of a kind of brand-new Si3N4, single ignition success rate 100%, the non-detonating phenomenon is used safer, adapt to the greasy dirt wet environment, anti-area carbon.And long service life, (circulation) used 100,000 times.Can light various fuel gas mixtures fast, reach 1000 degrees centigrade (use controllers) in the second, reach 1200 degrees centigrade in 2 seconds, various gas mixtures can be lighted.Do not have electromagnetic interference during work, make domestic gas instantaneous water heater more secure and reliable to use.
[description of drawings]
Fig. 1 is the cutaway view of embodiment of the present utility model;
Fig. 2 is the structural representation of the utility model igniter;
Fig. 3 is the circuit diagram of relay switch of the present utility model;
Fig. 4 is the circuit diagram of fet switch of the present utility model.
[specific embodiment]
The utility model will be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in Figure 2, a kind of igniter of domestic gas-fired water heater, comprise igniter 5, high temperature wire 10, the lead 10 outer fine pipes 9 of ripple that are surrounded by, igniter 5 mainly is made up of silicon nitride and molybdenum disilicide, high temperature is (the reaching 1200 degrees centigrade 2 seconds) by the big electric current generation of moment, be applied on the pot-type boiler, can use 6V, 12V and 24V's, what power can be with 10W and 20W, voltage need be controlled at+10%-15% between, this lead grip tube 9 is a fiberglass pipe, igniter 5 lower ends are equipped with holder 6, and this holder 6 is fixedlyed connected by flange 7 with lead 10, are provided with sealing ring 8 at flange 7 links.This igniter 1 is installed in the top around the burner 2, is higher than the position of fire row 4-8MM, can guarantee that like this combustion gas 4 in it is lighted, and this igniter is applicable on the control circuit that is connected with feedback pin 3.
Because of igniter removes to light flammable mixture with high temperature, and high temperature is the big electric current generation (reaching 1200 degrees centigrade 2 seconds) by moment, so the on/off of control point firearm has two kinds of methods, a kind of is the switch of being made igniter by relay, and another kind is a switch of being made igniter by FET.
As shown in Figure 3, be first kind of embodiment of the present utility model, its circuit diagram is made up of ignition signal 12, triode 13, diode 14, relay 15, power supply 16, igniter 5.
As shown in Figure 4, be second kind of embodiment of the present utility model, promptly by the switch of FET 17 as igniter, it comprises fiery signal 12, FET 17, igniter 5, power supply 16.
The course of work is: after the power on circuitry, the igniter heating power, and gas electromagnetic valve is in the valve state that closes, igniter is through the energising preheating in 2 seconds, the ceramic heating element top has reached 1200 degrees centigrade, at this moment valve is driven in gas electromagnetic valve energising, and combustion gas is lighted by the high temperature of burner chance igniter and taken fire.Under the preheat mode of igniter, gas electromagnetic valve is in and closes the valve state, has only after the temperature of igniter has reached firing temperature the gas electromagnetic valve valve of just switching on out.That is to say that gas electromagnetic valve energising duration of valve opening is that 1-4 after the igniter energising is after second.
Adopt the utility model of above technical scheme, have following beneficial effect:
This igniter has solved all drawbacks that spark ignition exists, and adopts the complete ceramic surface ignition device of a kind of brand-new Si3N4, single ignition success rate 100%, the non-detonating phenomenon, uses safer, adaptation greasy dirt wet environment, anti-area carbon.And long service life, (circulation) used 100,000 times.Can light various fuel gas mixtures fast, reach 1200 degrees centigrade in 2 seconds, various gas mixtures can be lighted.Do not have electromagnetic interference during work, make domestic gas-fired water heater more secure and reliable to use.
Should be noted that the above only is part possible embodiments of the present utility model, all should be contained within the utility model protection domain so all equivalent structures of being done according to the utility model claim scope change.
