Control device for methane combustion utensil

Abstract

The invention relates to a gas kitchen range controller, which comprises a power resource; a flame detecting unit, a valve control unit for controlling the gas supply; a logic control circuit, at least one group of liquid crystal panels on the control panel to display the setting and working condition; a control panel with several operation buttons and switches as the input interface to said logic control circuit, a clock part, a timing part, a timing controller to timing control said valve control unit to block the gas supply channel, a flame signal processing unit for analyzing the detected signal of said flame detecting unit, that when the flame is normal, keeping the gas supply channel open via said valve controller, and when the flame is abnormal, blocking the gas supply channel via said valve controller.

Description

technical field [0001] The invention relates to a gas burner control device, especially a multifunctional gas burner control device with automatic safety control and multi-reset setting Background technique [0002] According to the gas burner (gas stove for cooking, gas water heater) is a kind of appliance that is very widely used in cooking or heating at present, and although the general operating efficiency of the known gas burner is quite convenient, it is not as good as a general microwave oven. , induction cooker and other electric stoves can also be used for multi-functional control such as timing heating. In addition, because this kind of heating appliance uses flammable gas as fuel, if there is a little carelessness during use, gas will be generated. Leakage, causing gas poisoning, even gas explosion, fire and other major dangers; the above-mentioned problems are the shortcomings to be overcome by current gas burning appliances. [0003] It is currently known that ...

Problems solved by technology

[0004] For example: Taiwan Patent Announcement No. 00172382 "Safety Gas Furnace Controller Improvement Circuit (1)" patent case and Patent Announcement No. 00163892 "Novel Gas Burner Automatic Safety Control Circuit (2)" patent case proposed by the inventor of the present invention , the gas burner safety control circuit can display whether the driving power of the control circuit is normal when the gas stove is in use, save the power consumption of the safety automatic shutdown controller (solenoid valve), prevent the safety automatic shutdown controller from malfunctioning, and can The function of accurately setting the use time; however, the above-mentioned circuit does have the performance of accurately detecting the flame burning state and safely and automatically closing the gas supply valve, but its electronic circuit design is complex and the components are numerous, not only the production cost is high, but also the failure rate is relatively low. Improvement often leads to the failure of the overall safety control circuit to operate normally, and the purpose of setting up safety devices is lost; moreover, its complex electronic circuits and components consume a lot of power during operation. Frequent replacement of the battery can ensure the normal operation of the circuit, which makes users very troubled
