Abstract
The utility model provides a flameout protection device for double-head flame induction needle of a household gas cooker, consisting of a burner, an ignition controller, a gas valve and a gas pipe, wherein the gas valve is arranged on the gas pipe. The device is characterized in that a double-head flame induction needle is provided between the burner and the ignition controller; one end of the double-head flame induction needle connects with the ignition controller, and the other end connects with a grounding piece. The utility model further improves the flameout protection device of an ion induction needle and, overcoming defects of prior art, provides a flameout protection device for double-head flame induction needle which has the advantages of simple structure, convenient assembly, reliable safety as well as low cost and can independently constitute a flame induction signal circuit.
Description
Technical field
The utility model relates to gas combustion range flameout protector, a kind of double end flame inductive needle flame-out protection device of saying so more specifically.
Technical background
Existing household gas range flame induction flame-out protection device mainly contains two kinds on ion inductive needle and temperature sense pin.Its intermediate ion inductive needle is to constitute signal circuit by inductive needle and burner; start safeguard measure during fray-out of flame, stop gas leakage: but this mode produces and forms dirt etc. in oxidation and long-term the use and cause loose contact to make the flame induced signal not constitute the generation that the loop produces fault and causes security incident standing long term high temperature because of burner easily.The temperature sense pin is that the distortion of directly adopting the temperature-sensitive material temperature influence to produce starts safeguard measure; this type of device exists induction blunt; induction sensitivity and heat dissipation environment are closely related; and therefore shortcomings such as inductive material wears out under the effect of long term high temperature easily have bigger potential safety hazard.
Summary of the invention
The utility model is to do further improvement in the structure to the flame-out protection device of ion inductive needle; its purpose is to have overcome above-mentioned technical disadvantages; provide a kind of simple in structure; easy for installation; safe and reliable, cost of manufacture is low and can constitute the double end flame inductive needle flame-out protection device in flame induced signal loop alone.
The utility model mainly is achieved through the following technical solutions its goal of the invention:
The utility model is a kind of double end flame inductive needle flame-out protection device; form by burner, ignition controller, gas valve and Gas Pipe; gas valve is arranged on the Gas Pipe; it is characterized in that between burner and ignition controller, being provided with double end flame inductive needle; double end flame inductive needle one end is connected with flame detection circuit in the ignition controller, and the other end is connected with the ground strip of ignition controller.The utility model when kitchen range in when burning, flame contacts simultaneously on double end flame inductive needle, and double end flame inductive needle directly is connected with ignition controller, after the flame detection circuit that the loop signal that constitutes on the double end flame inductive needle directly enters ignition controller inside amplifies processing, thereby signal is delivered to the valve state of opening that the gas valve control circuit is kept gas valve, as when accident extinguishing occurring, because of the double end flame inductive needle sensing that is connected with flame detection circuit less than flare up fire, then the gas valve control circuit is driven valve because of nothing and is kept signal gas valve is closed.Thereby security incident and the personal injury of having avoided accident extinguishing to cause; also avoided simultaneously the fault and the security incident that are caused because of the burner loose contact; the utility model is a double end flameout protective device a kind of simple in structure, easy for installation, safe and reliable.
The utility model can be provided with one or more double end flame inductive needles.The number of the burner that is provided with according to gas furnace can all dispose double end flame inductive needle for each burner, makes each burner possess the function of independent blowout protection; Also can play the function of multiple protective to burner for burner is equipped with a plurality of double end flame inductive needles.
The utility model has kept the ground strip in original ion inductive needle technology, plays the function of duplicate protection, has alleviated the loss to double end flame inductive needle simultaneously, has increased the life-span of using.
Of the present utility modelly be a little:
1. adopt to constitute the double end flame inductive needle in flame induced signal loop alone, thereby stopped to produce and produce the fault that dirt etc. causes loose contact to cause in loose contact that oxidation causes and long-term the use because of burner stands long term high temperature;
2. only be on original blowout protection circuit, to do simple improvement, alleviated the cost of circuit design, make simple and easy;
3. employing double end flame inductive needle replaces the ion inductive needle in original technology, and is simple in structure, installs simple and easy;
4. be independently double end flame inductive needle of each burner configuration, make each burner that independently extinguish protection function all be arranged, be more convenient for daily use;
5. keep the grounding function of original ion inductive needle flame-out protection device and, play the function of multiple protective for burner is equipped with a plurality of ion inductive needles, safe and reliable.
