Abstract

The utility model discloses a safety gas range which can automatically cut off a gas source, ensuring safe in the flameout condition inartificially, the gas range is characterized in that an ignition burner and a thermocouple are arranged on a range burner; the thermocouple is connected with an electromagnetic valve by a thermocouple wire; one side of the electromagnetic valve is provided with a time control valve which is connected with a pressure transmission rod by a push rod; the pressure drive rod is arranged under a pan frame. The utility model has the advantages of high ignition efficiency, no burning of the range surface, long service life, and single regulation and total regulation with large, middle and small fire, and is suitable for cooking various eats; the utility model can cut off the gas source automatically in the flameout condition inartificially or take off the pot to prevent accidents from happening.

Description

Safety gas cooker

The utility model relates to a kind of non-artificial safety gas cooker that can cut off fuel gas source after flame-out automatically, belongs to a kind of kitchen range:

Existing gas-cooker does not generally have safety device, and what have adds safety device, but complex structure, maintenance is inconvenient.The gas combustion range ignition nozzle that uses is whenever lighted the kitchen range face that once then burns a time below the kitchen range face at present, thereby reduces the service life of kitchen range face.

The purpose of this utility model is to overcome the weak point in the background technology and provides a kind of simple and reasonable, and long service life is taken away after stopping working or with pot and can both be cut off source of the gas in back 5 minutes automatically, prevents the safety gas cooker that accident takes place.

The purpose of this utility model be achieved in that it be on the basis of automatic ignition gas-cooker, carry out improved, comprise kitchen range face, pallet, pot frame, release knob, igniting nozzle, piezoelectric ceramics, switch valve, air regulating board, the igniting Gas Pipe that is connected with the nozzle of lighting a fire, main feature is that igniting nozzle, thermocouple place on the kitchen range, and thermocouple links to each other with magnetic valve by thermoelectric coupling wire; Magnetic valve one side is equipped with time control valve, and time control valve links to each other with the pressure drive link by push rod, and the pressure drive link is positioned at below pot frame.

The purpose of this utility model can also reach by following technical measures: thermocouple and the corresponding setting of igniting nozzle; Kitchen range is three, one of them single fiery kitchen range, two fiery kitchen ranges, three fiery kitchen ranges; Igniting nozzle, thermocouple place the center of single fiery kitchen range, in the middle of the large and small pyrosphere of two fiery kitchen ranges, in the middle of the little middle pyrosphere of three fiery kitchen ranges, also are provided with a thermocouple between its big or middle pyrosphere.

Operation principle: when kitchen range burns, thermocouple produces electric current, make the magnetic valve adhesive, when the kitchen range fire extinguishes, do not produce electric current because of thermocouple can not get heat energy, the magnetic valve dead electricity, under spring action,, cut off fuel gas source with closed electromagnetic valve, after preventing to put out fire because of the soup class is excessive in the pot, combustion gas continues discharging and accidents caused generation.

After pot is taken away, the moving push rod of shipper pole on the pressure drive link decompression, the contact transfer time control valve, source of the gas is closed in action after 5 minutes, thereby after realizing taking away without chafing dish, even forget that close also can auto extinguishing, saves combustion gas and try to avert accidents thereby reach.

The utility model compared with prior art has following advantage:

1, owing to the igniting nozzle is installed on the kitchen range, so the ignition effectiveness height, the kitchen range face that do not burn, long service life;

2, since in the pot soup class excessive etc. non-artificial flame-out can the automatic self-closing gas source, try to avert accidents;

3, taking away when pot need not when fire, can cut off source of the gas automatically in 5 minutes, reaches the saving combustion gas, and the accident that prevents takes place;

4, have dull, the tracking function of large, medium and small fire, adapt to various foods and make required firepower;

5, the kitchen range air inlet pipe adopts flange-connection stainless steel metal flexible pipe, has advantages such as anticorrosive, anti-aging, easy scouring.

The explanation of accompanying drawing drawing:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model list kitchen range eye cutaway view.

Among the figure: air inlet pipe (1), change core valve (2), hose coupling (3), flexible pipe (4), kitchen range face (5), pot frame (6), pallet (7), two fiery kitchen ranges (8), thermocouple (9), igniting nozzle (10), release knob (11), single fiery kitchen range (12), three fiery kitchen ranges (13), air regulating board (14), kitchen range nozzle (15), piezoelectric ceramics (16), switch valve (17), igniting Gas Pipe (18), magnetic valve (19), time control valve (20), ignition lead (21), push rod (22), thermoelectric coupling wire (23), discharge needle (24), main air inlet pipe (25), pressure drive link (26), kitchen range air flue (27).

Below in conjunction with drawings and Examples in detail the utility model is described in detail:

Air inlet pipe (1) is connected with metal hose (4) by hose coupling (3), and being provided with between air inlet pipe (1) and hose coupling (3) changes core valve (2).Pallet (7), pot frame (6) are housed on the kitchen range face (5), are provided with pressure drive link (26) below pot frame (6), it links to each other with time control valve (20) by push rod (22).Metal hose (4) is communicated with main air inlet pipe (25), and main air inlet pipe (25) other end links to each other with time control valve (20).The utility model kitchen range is 3, i.e. three kitchen ranges, one of them single fiery kitchen range (12), two fiery kitchen ranges (8), three fiery kitchen ranges (13), the kitchen range eye can make as required, also can be made into series of products, single-hole range can be made into single fiery kitchen range (12), two fiery kitchen ranges (8), three fiery kitchen ranges (13); The eyes kitchen range can be made into the single, double fiery kitchen range of eyes, eyes list, three fiery kitchen ranges, eyes three fiery kitchen ranges; Three kitchen ranges can be made into three single, double, two fiery kitchen ranges, three single, double, three fiery kitchen ranges, three fiery kitchen ranges of list, three two, two, three fiery kitchen ranges, three two, three, three fiery kitchen ranges, three three, three, three fiery kitchen ranges.The center that igniting nozzle (10), thermocouple (9) place on the kitchen range, its igniting nozzle (10), thermocouple (9) correspondence are arranged on single fiery kitchen range (12), in the middle of the large and small pyrosphere of two fiery kitchen ranges (8), in the middle of little, the middle pyrosphere of three fiery kitchen ranges (13), also be provided with a thermocouple (9) between its big or middle pyrosphere, it is large, medium and small that the arranging of pyrosphere is followed successively by from outside to inside.Thermocouple (9) links to each other with magnetic valve (19) by thermoelectric coupling wire (23), being positioned at kitchen range face (5) front side release knob (11) links to each other with kitchen range nozzle (15) by switch valve (17), kitchen range nozzle (15) links to each other with kitchen range air flue (27), and its junction is provided with air regulating board (14).Switch valve (17) one sides are provided with igniting Gas Pipe (18), its other end links to each other with igniting nozzle (10), point high-voltage line (21) one ends alive link to each other with piezoelectric ceramics (16), another termination discharge needle (24), discharge needle (24) and the corresponding setting of igniting nozzle (10).Fig. 2 is the cutaway view of single kitchen range eye (i.e. kitchen range), and eyes kitchen range, three kitchen range controlling organization structures are identical with it, and controlling organization and kitchen range eye are complementary.
