Description
Technical field
The utility model relates to the gas furnace technical field, is specifically related to a kind of novel gas stove switch electronic timer.
Background technology
Household gas range is principal home front yard cooker.Due to household gas range, take petroleum gas and be main fuel, caloric value is large, and belongs to naked light, therefore, uses safely particularly important.Protector of accident extinguishing mostly is housed on existing household gas range, but automatic self-closing gas kitchen range switch while being mainly used in gas leakage.
Blowout protection mode commonly used has three kinds in the market: heat-sensitive type, thermoelectric (al) type and photo-electric.
Heat-sensitive type: claim again double-metal sheet type.Bimetal leaf is that the metal-made by two kinds of different coefficients of expansion closes and forms, under the effect of temperature, the metal that the coefficient of expansion is large simultaneously can be crooked to the little metal one side of the coefficient of expansion, when losing temperature, the metal of former expansion bending can slowly return to original state again, so bimetal leaf is called again memorial alloy.By the sensor of bimetal leaf as safety guard, utilized just the characteristic of bimetal leaf expansion bending under temperature action.The advantage of bimetal leaf protective device be simple in structure, cost is low.Shortcoming is that difficulty is installed, and there is to very high requirement the installation site of bimetal leaf and the cooperation of plug valve and gas valve, and thermal inertia is large, drives valve and close time of valve longer, and service life is short.
Thermoelectric (al) type: this device is also the heat energy produced while having utilized fuel gas buring.The thermoelectric (al) type flame-out protector is comprised of thermocouple and magnetic valve two parts, and thermocouple is to be combined by two kinds of different alloy materials.Different alloy materials can produce different thermoelectrical potentials under the effect of temperature, the different manufacture of the thermoelectrical potential that thermocouple utilizes the different-alloy material to produce under the effect of temperature just forms, and it has utilized the electric heating difference of different-alloy material.When pressing knob, when little fire was lighted, thermocouple was heated by its flame, produced thermoelectrical potential.Thermoelectrical potential imports solenoid by wire, produces magnetic field and makes the magnetic valve adhesive, and gas valve is opened, the burning path is opened, and maintains its normal combustion, overflows in case run into strong wind or soup etc., stamp out the flames, the thermoelectrical potential of thermocouple drops to zero very soon, coil losing electricity, and magnetic valve lost efficacy, under spring action, reset rapidly, the valve closing fuel gas path, stop air feed, guarantees safety.The thermoelectric (al) type safety guard is simple in structure, easy for installation, cost is low, is used widely at present.But this kind protective device is usingd thermocouple as heat sensor, shortcoming is that thermal inertia is large, reaction speed is slow, makes the people feel operation inconvenience.
Photo-electric: also claim ion induction type.This device be utilize combustion gas when burning flame with ion and have the unilateal conduction characteristic.This safeguard protection mode is used on gas heater the earliest, and by early stage direct current induction, develops into present alternating current impression, makes reliability obtain significantly improving, and is applied in the history of also only having 3 or four years on kitchen range.The photo-electric cost is high, and technology is immature.
At present, the safety shutdown device that the gas-cooker of main flow adopts is thermoelectric (al) type, but in the process of using household gas range, owing to answering the call or other urgent things are left, forgets and closes fire, is easy to cause the accident.Especially the Baoshang of gradually accepting for the whole nation in Guangdong prevailing, after big fire is boiled, need little fire stewing boiling for a long time, if relied on the manpower monitoring flame-out, is easy to make to cook unsuccessfully for forgeing or incuring loss through delay due to the people, and security incident even occurs.Therefore, be necessary to provide a kind of timer and described safety shutdown matched with devices to use, can be after the time of setting auto extinguishing.But fixed pattern device in the market mostly adopts or contains mechanical device, and the life-span is short, poor reliability.
