Abstract
The utility model discloses an anti-backfire domestic gas stove which comprises a bottom shell, a panel, a gas valve, an electromagnetic valve on the gas valve, a controller, a burner, an ignition needle and a thermocouple, and further comprises an anti-backfire plate and a temperature sensor, wherein the anti-backfire plate comprises a base plate and a fire baffle plate; the base plate is in fit with air inlet end faces of an inner injecting pipe and an outer injecting pipe; an nozzle runs through a nozzle inserting hole formed in the base plate and is inserted in nozzle holes of the inner injecting pipe and the outer injecting pipe, and a primary air hole is aligned to an air hole; the fire baffle plate is arranged above the nozzle; the temperature sensor is arranged on the upper surface of the fire baffle plate and is connected to the controller. In case of backfire in the gas stove, gas burns to heat the anti-backfire plate when gas burns in the gas stove, a signal is transmitted to the controller through the temperature sensor and reverse electromotive force is transmitted to the electromagnetic valve through the controller, so as to forcedly turn off the electromagnetic valve and cut off a gas path; therefore, backfire flames go out to take a protecting action.
Description
Technical field
The utility model relates to a kind of household gas utensils.
Background technology
Currently available technology, a kind of anti-backfire household gas utensils, comprise drain pan, panel, gas valve, be arranged on magnetic valve, controller, burner, ignition electrode and thermocouple on gas valve, described burner comprises burner, burner comprises interior induction tunnel and outer induction tunnel, has nozzle bore and the airport that is positioned at nozzle bore both sides on the injection mouth of pipe of interior induction tunnel and outer induction tunnel; Controller is connected with ignition electrode, and thermocouple is connected with magnetic valve.Existing problems: when gaseous-pressure is low or burner is installed marquis when incorrect, fire is easy to burn at nozzle place, because nozzle is generally all contained in gas-cooker inside, burning causes gas utensil to damage, even explode, cause fire hazard, the face glass that combusts for a long time gas kitchen as naked light can cause glass breakage; If burn out fuel gas pipeline, may cause gas leakage, cause blast or fire.
Summary of the invention
The purpose of this utility model is: a kind of anti-backfire household gas utensils are provided, and its tool is when gas kitchen ranges generation tempering, and in the time of gas-cooker internal-combustion, Self-shut electromagnetic valve cuts off fuel gas pipeline, has eliminated potential safety hazard.
The utility model is achieved in that a kind of anti-backfire household gas utensils, comprise drain pan, panel, gas valve, be arranged on magnetic valve, controller, burner, ignition electrode and thermocouple on gas valve, on two escape pipes of gas valve, be provided with nozzle; Described burner comprises burner, and burner comprises interior induction tunnel and outer induction tunnel, has nozzle bore and the airport that is positioned at nozzle bore both sides on the injection mouth of pipe of interior induction tunnel and outer induction tunnel; Controller is connected with ignition electrode, and thermocouple is connected with magnetic valve; It is characterized in that: also comprise anti-backfire plate and temperature sensor,
Described anti-backfire plate comprises seat board and fireguard, has the hole group corresponding with interior induction tunnel and outer induction tunnel on described seat board, and a hole group comprises a nozzle spliced eye and the primary air hole that is positioned at the nozzle spliced eye left and right sides;
The air inlet end face laminating of described seat board and interior induction tunnel and outer induction tunnel, in nozzle inserts through the nozzle receptacle on seat board, in the nozzle bore of induction tunnel and outer induction tunnel, primary air hole and airport align; Fireguard is positioned at the top of nozzle;
Described temperature sensor is arranged on the upper surface of fireguard, and temperature sensor is connected with controller.
The anti-backfire household gas utensils of described one, its special character is: on the lower surface of described fireguard, have poly-fiery chamber.
A kind of anti-backfire household gas utensils of the utility model; when gas kitchen ranges generation tempering; in the time of gas-cooker internal-combustion; fuel gas buring heating anti-backfire plate, temperature sensor passes the signal along to controller, and then controller sends inverse electromotive force to magnetic valve; make magnetic valve positive closing; cut off combustion gas gas circuit, back fire flame is extinguished, thereby played a protective role.

As shown in Figure 1 and Figure 2, a kind of anti-backfire household gas utensils, comprise drain pan (not going out in figure), panel 1, gas valve 2, be arranged on magnetic valve 21, controller 3, burner 4, ignition electrode 5 and thermocouple 6 on gas valve 2, described burner 4 comprises burner 41, burner 41 comprises interior induction tunnel 42 and outer induction tunnel 43, has nozzle bore and the airport that is positioned at nozzle bore both sides on the injection mouth of pipe of interior induction tunnel 42 and outer induction tunnel 43; Controller 3 is connected with ignition electrode 5, and thermocouple 6 is connected with magnetic valve 21, on two escape pipes 22 of gas valve 2, is provided with nozzle 9.
Also comprise anti-backfire plate 7 and temperature sensor 8, as shown in Figure 3, described anti-backfire plate 7 comprises seat board 71 and fireguard 72, on described seat board 71, have the hole group corresponding with interior induction tunnel and outer induction tunnel, a hole group comprises a nozzle spliced eye 711 and the primary air hole 712 that is positioned at the nozzle spliced eye left and right sides;
Described seat board 71 is fitted with the air inlet end face of interior induction tunnel 42 and outer induction tunnel 43, and in nozzle 9 inserts through the nozzle receptacle 711 on seat board 71, in the nozzle bore of induction tunnel 42 and outer induction tunnel 43, primary air hole 712 and airport align; Fireguard 72 is positioned at the top of nozzle 2;
Described temperature sensor 8 is arranged on the upper surface of fireguard 72, and temperature sensor 8 is connected with controller 3.
On the lower surface of described fireguard 72, there is poly-fiery chamber 721.
Above-described is only preferential embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, in the situation that not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
