The structure of the utility model comprises a gas cooker shell, a cooker panel, a jamb, a work stand, a gas pipe line, a hand control valve, a hand switch, a pulse igniter and a fire disc. The utility model is characterized in that the utility model is provided with the safety control device which comprises a safety valve, a connecting bar and a copper-based shape memory alloy piece, wherein the safety valve is arranged between a main muzzle and the hand control valve, one end of the copper-based shape memory alloy piece is fixed and the other end is connected with the rotating bar of the safety valve by the connecting bar.
Description
What the utility model safety gas range related to is a kind of flame-out gas appliance of closing the source of the gas safety control automatically that has, and is applicable to places such as family, dining room, dining room, restaurant.
At present, life sources of the gas (abbreviation coal gas) such as natural, the artificial coal gas that China resident uses hots plate, warms oneself, liquefied gas are a kind of energy efficiently, be again a kind of easily right, explosive and poisonous hazardous gas, reach finite concentration in case leak, will cause catastrophic failures such as personnel's poisoning, fire even blast.Gas range is the indispensable daily life tools of China resident family.When there was non-normal flameout in present gas appliance, main control valve was shown in an open position all the time, caused coal gas to external leakage.Although existing many indoor gas leakage alarm tools, but still do not break through the level that the gas range accident extinguishing cuts off source of the gas automatically, thereby also do not have effectively to solve the problems such as disaster that the coal gas accidental release causes of taking precautions against.
The purpose of this utility model is to provide a kind of safe gas range at above-mentioned weak point, has the gas appliance safety control, make kitchen range automatic closed safe valve when non-normal flameout, stop coal gas to leak outside, and when the kitchen range operate as normal, be in open mode, and guarantee the kitchen range operate as normal, safe and reliable, easy to use, good energy-conserving effect.
Safe gas range takes following scheme to realize: safe gas range structure comprises gas range housing, range panel, burner, pot frame, gas pipeline, hand control valve, hand switch, pulse igniter, flame disk, safety control.Range panel is arranged at gas range housing top, the burner device is in the gas range housing, and the burner upper unit has flame disk, and device has hand switch on the gas range housing front panel, hand switch links to each other with hand control valve, and the hand control valve device is at gas range housing front panel rear portion.The safety control structure comprises safety valve, connecting rod, copper-based shape memory alloy sheet.Safety valve is made of valve body, spool, dwang, holddown spring.Spool is a cone-shaped.Safety valve be installed on that main jet is chewed and hand control valve between, the one end links to each other with hand control valve, the copper-based shape memory alloy sheet is a metallic object that is convexly curved.Copper-based shape memory alloy sheet one end is fixed on the burner, and the other end links to each other with the dwang of safety valve by connecting rod, and the copper-based shape memory alloy sheet is installed on the thermal site that is subject to that main jet is chewed the lower end.
Operation principle: when main jet is chewed ignition operation, hand switch is opened gas passage, and make marmem sheet distortion by the connecting rod effect, main jet is chewed normal combustion after the several seconds, the heat energy that the copper-based shape memory alloy sheet relies on main jet to chew burning continues to keep is shown in an open position safety-valve, thereby guarantees the kitchen range operate as normal.When accidental cause stops working kitchen range, because shrinking, the cooling of copper-based shape memory alloy sheet restores, by connecting rod cone rotary valve safety valve cuts out, close the gas passage of coal gas main control valve, thereby close coal gas, play flame-out automatic protective effect.
Close coal gas normally, promptly close manually-operated gate, this moment, gas piping stopped ventilation, flame does not extinguish because there being enough fuel, shortage of heat is so that the marmem sheet is kept labile state, and the marmem sheet recovers stable state equally, and gas range has recovered prefiring state.
Flame-out safety control of closing source of the gas is automatically set up in safe gas range employing at the source of the gas gauge tap position of ordinary gas stove, this flame-out core component of compressed air source unit of cutting out automatically is by a kind of copper-based shape memory alloy sheet control of lowering the temperature and restoring, can in the several seconds after kitchen range burning things which may cause a fire disaster accident is extinguished, close source of the gas automatically, thereby can fundamentally stop the generation of gas leak disaster accident.
The utility model is reasonable in design, simple in structure, and fitting operation is convenient, and the duration of ignition is fast, is to solve the relieved use gas appliance of huge numbers of families' safety, the ideal device of avoiding contingency to take place.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the front view of safe gas range.
Fig. 2 is the vertical view of safe gas range.
Fig. 3 is the safety valve structure schematic diagram of safe gas range.
Fig. 4 is the safety control structural principle schematic diagram of safe gas range.
With reference to accompanying drawing, safe gas range structure comprises gas range housing 22, range panel 2, burner 13, pot frame 21, gas pipeline 10, hand control valve 5, hand switch 20, pulse igniter 4, flame disk 2, safety control.Range panel is arranged at gas range housing 22 tops, burner 13 devices are in gas range housing 22, and burner 13 upper units have flame disk 2, and device has hand switch 20 on gas range housing 22 front panels, hand switch links to each other with hand control valve 5, and hand control valve 5 devices are at gas range housing front panel rear portion.With reference to accompanying drawing, the gas range safety control mainly comprises safety valve, connecting rod 11,12,14, copper-based shape memory alloy sheet 3.Safety valve is made of valve body 6, spool 7, dwang 17, holddown spring 8.Spool 7 devices are in valve body 6, and spool is a cone-shaped.Dwang 17 is equipped with on spool top, and holddown spring 8 is equipped with in the spool bottom.Safety control valve be installed on main jet chew 18 and hand control valve 5 between, its front end links to each other with hand control valve 5 by valve seat 19 usefulness bolts, the other end is chewed 18 external screw thread by internal thread and main jet and is fastenedly connected.Spool 7 and valve seat 19, holddown spring 8 are installed on the safety valve, and there is through hole 15 at spool 7 middle parts, and top links to each other with dwang 17, and holddown spring 8, post means are arranged at the bottom, and holddown spring 8 is pressed on bullet spool 7 on the taper hole of valve body.Copper-based shape memory alloy sheet 3 one ends are fixed on the fixing point 9 of burner 13, and the other end links to each other with connecting rod 12 by swivel pin.Copper-based shape memory alloy sheet 3 is installed on the below of main flame disk 2.When hand control valve 5 is opened, the spool 7 of safety valve is rotated, open gas distribution channel 16, and make 3 distortion of marmem sheet, pulse igniter 4 igniting by connecting rod 11,12,14, dwang 17, light main flame disk 2, after several seconds, copper-based shape memory alloy sheet 3 continues to maintain labile state under main flame disk 2 heat energy effects, it is motionless to make the spool 7 of safety valve remain on open position, the normal air feed work of kitchen range.When kitchen range master flame disk 2 extinguished because of accident, 3 coolings of copper-based shape memory alloy sheet were shunk and are restored, and make the spool 7 of Safety control valve turn to the closed position by connecting rod 11,12, cut off gas distribution channel 16, thereby play the blowout protection effect, stop coal gas to leak outside.
