Thus, to achieve the discharge of the ignition needle, the voltage at the discharge end is higher than the voltage at the receiving end, and a voltage difference is generated between the two ends to achieve the discharge between the two ends. The receiving end may be grounded, in which case the thermocouple is grounded by a housing connected to the gas valve.

[ detailed description ] of the utility model
For a further understanding of the objects, constructions, features, and functions of the present application, the cooperating embodiments are described in detail below.
As shown in fig. 1 and 2, the gas range includes a burner 1, an ignition needle 2 and a thermocouple 3 positioned in the vicinity of the burner 1. The ignition needle 2 has a discharge end 4, and the discharge end 4 is used for igniting the fuel gas sprayed from the burner 1.
The thermocouple 3 serves as a receiving end for the discharge of the ignition needle 2, and ignition spark or continuous arc is generated between the discharge end 4 and the thermocouple 3 at the time of ignition to ignite the gas ejected from the burner 1.
The discharge end 4 of the ignition needle 2 discharges in the direction of the thermocouple 3, so that a stable ignition loop is formed among the ignition needle 2, the thermocouple 3 and the valve after the switch knob is pressed during ignition, and ignition flowers or continuous electric arcs are generated between the discharge end 4 and the thermocouple 3 to ignite fuel gas sprayed from the burner 1, thereby improving the ignition efficiency and realizing quick ignition.
If the ignition needle 2 discharges towards the inner ring fire cover 5, after the switch knob is pressed during ignition, an ignition loop is formed among the inner ring fire cover 5, the fire cover base, the furnace end, the ignition needle 2 and the valve body, the number of contacts among the ignition loops is relatively large, the fire cover base and the furnace end are movably connected, and as long as one contact is not well connected or a part with an insulating coating is used, the risk of non-conduction can be brought to the discharge loop, even the phenomenon of ignition leakage occurs in the ignition loop, and the possibility of ignition failure can be brought. By adopting the scheme of the embodiment, the ignition circuit has fewer contacts, different parts are fixedly connected, and the connection relationship is stable, so that the ignition circuit is stable and reliable, the energy loss is reduced, and the ignition efficiency and the ignition success rate are improved.
The ignition needle 2 includes an electric spark electrode 7 and an insulating case 8 wrapped around the electric spark electrode 7, and the insulating case 8 is made of ceramic material. The end of the spark electrode 7 is exposed to the housing. The ignition electrode includes a discharge end 4 exposed outside the housing, the discharge end 4 being located at the end of the ignition electrode exposed outside the housing.
The gas range further includes a gas valve (not shown) for controlling gas, which is used to adjust the flow rate of gas supplied to the burner 1.
The thermocouple 3 is made of copper and other special metal materials. The thermocouple 3 is fixedly connected to the shell of the gas valve, the thermocouple 3 is grounded, and the thermocouple 3 serves as a grounding end when the ignition needle 2 discharges and also serves as a receiving end when the ignition needle 2 ignites.
To achieve the discharge of the ignition needle 2, the voltage of the discharge terminal 4 is higher than the voltage of the receiving terminal, and a voltage difference is generated between the two terminals to achieve the discharge between the two terminals. In this embodiment, the thermocouple 3 is a receiving terminal, and the receiving terminal is grounded, so that a voltage difference is generated between the discharge terminal 4 and the thermocouple 3, and when the ignition needle 2 is ignited, a continuous arc is generated between the discharge terminal 4 and the thermocouple 3, thereby realizing rapid and stable ignition.
The thermocouple 3 is used for flameout protection of the gas stove at the same time, after the flame burns to the thermocouple 3, induced electromotive force can be generated and used as a signal for controlling to open a gas source, and when the flame is extinguished, the electromotive force is rapidly reduced, and the gas source is closed. Before ignition, the thermocouple 3 is not burned by flame, and the induced electromotive force is zero, so that the thermocouple can be used as a grounding structure for ignition.
The burner 1 comprises an inner ring flame cover 5 and an outer ring flame cover 6 arranged around the inner ring flame cover 5, the ignition needle 2 and the thermocouple 3 being located between the inner ring flame cover 5 and the outer ring flame cover 6.
Wherein the distance from the discharge end 4 to the thermocouple 3 is smaller than the distance from the discharge end 4 to the inner annular fire cover 5. When the discharge end 4 of the ignition needle 2 discharges, the thermocouple 3 relatively close to the discharge end 4 becomes a receiving end, the discharge end 4 discharges towards the thermocouple 3, and electric sparks are generated between the discharge end 4 and the thermocouple 3, so that rapid and stable ignition is realized.
The distance between the discharge end 4 and the thermocouple 3 is between 2mm,5 mm. In a preferred embodiment, the distance between the discharge end 4 and the thermocouple is 4mm.
If the ignition distance is too large, the arc between the discharge end 4 and the thermocouple 3 is liable to be unstable, the discharge direction of the discharge end 4 is not liable to be fixedly directed toward the thermocouple 3, the spark energy is not concentrated, and rapid ignition is not liable to occur. When the distance between the discharge end 4 and the thermocouple 3 is in the range of 2mm and 5mm, the electric arc is stable, the discharge direction is fixed, and the spark energy is more concentrated, so that the rapid ignition is easier.
In one embodiment, as shown in fig. 4, the discharge end 4 is inclined toward the thermocouple 3. In an alternative embodiment, as shown in fig. 5, the thermocouple 3 is inclined towards the discharge end 4. This not only shortens the distance between thermocouple 3 and discharge end 4, but also is favorable to discharge end 4 to thermocouple 3 direction, and the discharge direction is stable, and spark energy is more concentrated, is favorable to quick ignition.
In a further embodiment, as shown in fig. 3, the device further comprises a metal accessory 9 sleeved on the thermocouple, and the metal accessory 9 extends towards the discharge end 4 of the ignition needle 2, and the distance between the metal accessory 9 and the thermocouple 3 is smaller than the distance between the ignition needle 2 and the thermocouple 3. This not only shortens the ignition distance further, makes the spark energy more concentrated, but also the discharge direction of the ignition needle 2 is more stable, which is advantageous for realizing rapid ignition.
