Pulse ignition system of field effect ion induction stove

Abstract

The invention relates to a pulse ignition system of a field effect ion induction stove. The pulse ignition system comprises a stove, an igniter, a starting switch, a battery assembly and an electromagnetic valve, wherein the stove is provided with a plurality of burners; the igniter is respectively connected with the plurality of burners of the stove through a plurality of flame detection wires; the flame detection wires are used for transmitting the burning state signals of the burners to the igniter; the starting switch, the battery assembly and the electromagnetic valve are respectively connected with the igniter; the starting switch is used for providing an ignition or fire extinguishing signal for the igniter; the battery assembly is used for supplying power to the igniter; the electromagnetic valve is arranged in a gas passage; the igniter controls the opening and closing state of the electromagnetic valve, so that the igniter controls gas supply of the stove by means of the electromagnetic valve; and the igniter comprises a singlechip and a field effect tube, and the field effect tube is connected with the singlechip.

Description

technical field [0001] The invention relates to an ignition control system for a cooker, in particular to an ignition system for a cooker that detects and controls the ignition state of the cooker through a field effect tube. Background technique [0002] As we all know, with the progress of society, more and more appliances that can improve the quality of people's daily life are becoming more and more common in people's lives. Gas cookers are such appliances. Gas cookers generally use natural gas, liquefied petroleum gas 1. Artificial gas is used as a fuel to burn a stove, and the use of a gas stove to assist people in cooking food can improve cooking efficiency and simplify people's cooking work. [0003] The ignition methods adopted in the market for gas cookers mainly include the use of tinder, manual ignition with a point gun, piezoelectric ignition, and pulse ignition. [0004] Now the country compulsorily requires all cookers to have a flameout safety protection devi...

AI Technical Summary

Problems solved by technology

Cause flammable gas leakage, there is a serious safety hazard

[0008] 3. When the cooker is in use, when the soup overflows and pours onto the flame detection needle, the igniter will cause the cooker to shut down incorrectly under the condition of normal combustion.

[0009] 4. The igniter is used on the stove of the infrared burner. If the soup overflows between the flame detection needle and the ceramic plate, it will cause the flame to go out without closing the solenoid valve and cause gas leakage. This is a fatal safety hazard. Such phenomena can easily cause fire or gas explosion

[0010] 5. Since the negative voltage of the ion induction pulse igniter currently used in the market is an analog negative voltage, the input impedance is small and the insertion loss is large

Affected by the electrical conductivity of the burner material and coating, the igniter used on the burner with poor conductivity often works at full power, which consumes a lot of power, does not save electricity, does not save energy, is not environmentally friendly, and has a short service life of the battery. And this is the main shortcoming of traditional technology
