Description
Technical field
The present invention relates to a kind of household gas range, specifically is a kind of gas combustion range flameout protector.
Background technology
Along with popularizing of household gas range, the safety in utilization of household gas range also comes into one's own day by day, and flame-out protection device is in the gas-cooker use, and flame runs into that wind or boiling water such as overflow at fortuitous event and when extinguishing, a kind of device that cuts off combustion gas automatically.At above-mentioned several conditions of being deeply in love, the household gas range standard GB 16410-2007 of new edition stipulates that clearly all household gas ranges comprise that desk-top and embedded gas-cooker must install flame-out protection device.The application of flame-out protection device has greatly improved the safety in utilization of gas-cooker.At present household gas range flame-out protection device structure applications is commonplace two kinds of versions:
1. thermoelectric (al) type flame-out protection device, its structure is that magnetic valve is installed in the gas-cooker plug valve gas circuit structure, and has a thermocouple to be connected with magnetic valve, the thermocouple temperature sensitive position is installed on the burner fire hole site.Its operation principle is after the operator presses down the plug valve rotating shaft and the spool of outwarding winding, the push rod that is installed in the plug valve backs down magnetic valve, combustion gas this moment gas circuit is connected, burner flame is lighted, be installed on the cool and thermal power kinetic potential that thermocouple on the burner utilizes flame to produce and make magnetic valve be held open state, the operator can unclamp the plug valve rotating shaft and made push rod break away from magnetic valve this moment.When the flame accident was extinguished, thermocouple can't produce electromotive force and offer magnetic valve owing to can not get the heat energy that flame produces, thereby magnetic valve cuts out the cut-out gas source automatically.But; there is following shortcoming in this blowout protection structure: on the one hand; the unlatching of magnetic valve is to be backed down by the push rod that is installed in the plug valve; this just requires the operator knob must be depressed the position of fully magnetic valve being backed down up to push rod when opening plug valve, so the plug valve internal structure is with regard to more complicated.On the other hand; because being held magnetic valve to the enough electric currents of generation by flame heat, thermocouple needs 3～5 seconds time; therefore the operator also needs the gas-cooker knob is pressed the normal startup that just can loose one's grip in 3～5 seconds with the assurance flame-out protection device after gas-cooker flame is lighted, and brings many inconveniences to the operator.
2. ion flame sensing type flame-out protection device, its structure is that a self-priming magnetic valve is installed on the gas-cooker air inlet pipe, general No. 1 dry cell power supply of two joints that adopts of self-priming magnetic valve is equipped with the ion flame-sensing needle that is used to survey flame in each burner fire hole site.Its operation principle is: when the operator opens the plug valve igniting, self-priming magnetic valve self-priming circuit is connected and is opened automatically, the combustion gas gas circuit is connected, and this moment, the ion flame-sensing needle detected burner flame, and signal is passed to ignition controller, ignition controller control self-priming magnetic valve is held open state, when the flame accident was extinguished, the ion flame-sensing needle was surveyed less than burner flame, and signal is passed to ignition controller, ignition controller control self-priming closed electromagnetic valve, thus fuel gas path cut off.But; the defective of this flame-out protection device is: on the one hand; because structural limitations; the self-priming magnetic valve is installed on the air inlet pipe and can only installs one; self-priming magnetic valve and all burners polyphone; therefore when gas-cooker is provided with two or more burners, can't accomplish blowout protection one to one, promptly any one burner flame accident extinguishes that then all burners will be by Close All.On the other hand, because the self-priming magnetic valve is kept the required power supply of opening and all provided by battery, therefore the power consumption of this blowout protection structure is bigger, and the battery altering frequency is higher.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of make stopcock structure simple, need not the blowout protection that prolongs the knob spinning time, can realize single burner and can save the gas combustion range flameout protector of battery.
For solving the problems of the technologies described above; a kind of gas combustion range flameout protector provided by the invention; comprise plug valve; the self-priming magnetic valve; burner; thermocouple; microswitch; the igniting pin; controller; battery; described microswitch is contained on the plug valve and with the controller lead and is connected; described igniting pin is connected with the controller lead; described thermocouple head is connected on the burner; its head is positioned at burner fire hole next door; described controller is connected with battery lead. and described self-priming magnetic valve is at plug valve and be connected between the gas-distributing pipe on the burner; described self-priming magnetic valve is connected with thermocouple wire, and is connected with the controller lead.
After adopting above structure, owing to adorned the self-priming magnetic valve between plug valve and burner gas-distributing pipe, stopcock structure is just simple, need not to install post rod mechanism.Magnetic valve is to utilize powered battery when opening, and then need not to prolong the spinning time of knob.Be to utilize thermoelectricly to meet the electromotive force power supply that flame heat energy produced by chance and be held open state after magnetic valve is opened, therefore need not powered battery, thereby can save battery.Moreover the self-priming magnetic valve is to be contained on the gas-distributing pipe of each burner of gas-cooker, can realize separately protected behind the burner accident extinguishing.
