Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0021] see figure 1 and figure 2 , an over-temperature automatic flameout protection method for a gas cooker, which uses a temperature sensing probe assembly 1 and a temperature control body 2, the temperature control body 2 is connected with a solenoid valve on the gas cooker to form a circuit, and the sensor of the temperature sensing probe assembly 1 The temperature package 4 sticks to the heated object above the gas cooker. When the heated object above the gas cooker reaches a certain temperature value, the medium in the temperature sensor package 4 expands and pushes the elastic element in the temperature control body 2 to move, thereby cutting off the circuit and starting To the role of automatic flameout protection.

[0022] see figure 1 and figure 2 , a body expansion type gas cooker over-temperature automatic flameout protection device, w...

Abstract

The invention discloses an automatic over-temperature flame-out protection method and device for a gas stove. The device comprises a temperature sensing probe component and a temperature control main body, wherein the temperature control main body is connected with an electromagnetic valve on the gas stove to form a loop; a temperature sensing bulb of the temperature sensing probe component is attached to a heated object above the gas stove; when the heated object above the gas stove reaches a certain temperature value, a medium inside the temperature sensing bulb expands to push an elastic element inside the temperature control main body to act so as to cut off the loop, and thus an automatic flame-out protection effect is achieved. The method and the device can meet the pan demands during normal heating or cooking and cut off the gas in over-heating, and thus the gas security is ensured.

Description

technical field [0001] The invention relates to the field of gas cookers, in particular to an over-temperature automatic flameout protection method and device for a body-expansion gas cooker. Background technique [0002] With the continuous improvement of living standards, people generally use gas cookers. Although there are also gas cookers with safety devices to produce now, generally thermocouples or probes are always installed on the stove to realize accidental flameout and shut off gas in its structure. The Chinese patent once disclosed a complete set of components consisting of burners, thermocouples, timers, electromagnets, springs, cams, push rods, action sleeves, pull rods, piezoelectric ceramics, ignition valves, intake pipes, valves, etc. The automatic multi-function safety gas oven (96213243.8) is characterized in that a safety valve locked by a low-melting point alloy pin is connected to the gas supply line, and a flame-out automatic control device controlled ...
