Full premix is controlled fuel gas frying stove automatically
The present invention relates to a kind of stir-fry stove, particularly a kind of full premix is controlled fuel gas frying stove automatically.
Gas furnace has been that broad masses use, traditional gas furnace, and its combustion gas is just to mix with air while being transported on burner ignition, and to obtain oxygen, there is air undermixing in this mode, burns insufficient, causes the thermal efficiency lower, and combustion gas is wasted.Have subsequently the jet type gas furnace that is transported to again burner burning after first combustion gas being mixed with air, but existing jet type gas furnace, due to structural defect, when being used, reality still exist combustion gas to mix the weak points such as even not, thermal loss is large with air.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of heat utilization efficiency is high, and burning velocity is fast, and high, easy to use, the reliability and durability full premix of flame temperature is controlled fuel gas frying stove automatically.
In order to solve the problems of the technologies described above, full premix of the present invention is controlled fuel gas frying stove automatically, comprise burner hearth, air blast, gas pipeline, burner hearth middle part is provided with burner, described gas pipeline is provided with air valve, air valve outlet connects respectively Chang Minghuo tracheae and fries stove supervisor, and stir-fry stove supervisor back end inside diameter narrows and be provided with elongated gas nozzle, external diameter is connected with mixing tube, and the mixing tube other end is communicated with burner; Described burner hearth is the double-layer stainless steel structure of hollow, and burner hearth interlayer is provided with into and out of air port, and air inlet connects air blast by airduct, and air outlet is communicated with the mixing tube at gas nozzle root place by warm-air pipe, forms the hot-air channel that enters mixing tube.
Further improvement of the present invention, the valve hinges outside of described air valve is connected with tooth plate, and upper tooth plate is provided with the shifting block that can control a motor switch contact action, and motor switch is electrically connected to air blast and ignition system; Described blower export is provided with lateral, and lateral is provided with air door in corresponding air valve position, and this air door outside is provided with lower tooth plate and is connected with upper tooth plate by chain; Upper tooth plate is provided with outward pulls handle.
Further improvement of the present invention, described stir-fry stove supervisor is provided with two-way.
Further improvement of the present invention, described stir-fry stove supervisor's front portion is provided with magnetic valve, and magnetic valve is electrically connected to anti-empty burning device.
The invention has the beneficial effects as follows: during work, air is introduced into the preheating of burner hearth interlayer, then from burner, spray after fully mixing with combustion gas, effectively improved heat utilization efficiency, make burning velocity fast, flame temperature is high; Burner hearth is that double-layer stainless steel material is special, and in burner hearth, heat loss is few, neat and artistic, and in addition, owing to adopting metal structure, in burner hearth, without laying bricks, cooking stove is slimmer and more graceful, transports more convenient; Because gas nozzle is elongated design, combustion gas is just ejection after gas nozzle stretches into mixing tube one segment distance, separated by a distance with the entrance of pressure-air, has avoided the impact of pressure-air stream on combustion gas normal discharge; On the other hand, owing to adopting interlock to control, after opening point internal heat valve, automatic ignition and the automatic blower fan that starts, igniting and speed on fire are fast, and firepower is easy to adjust.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
The specific embodiment
Shown in Fig. 1, full premix is controlled fuel gas frying stove automatically, comprise burner hearth 1, air blast 2, gas pipeline 3, burner hearth 1 middle part is provided with burner 4, gas pipeline 3 is provided with air valve 5, air valve 5 outlet connects respectively Chang Minghuo tracheae 6 and fries stove supervisor 7, fries stove and is responsible for that 7 back end inside diameter narrow and be provided with elongated gas nozzle 71, external diameter is connected with mixing tube 8, and mixing tube 8 other ends are communicated with burner 4; The double-layer stainless steel structure that burner hearth 1 is hollow, burner hearth 1 interlayer is provided with into and out of air port, and air inlet connects air blast 2 by airduct 21, and air outlet is communicated with the mixing tube 8 at gas nozzle 71 root places by warm-air pipe 22, form the hot-air channel that enters mixing tube 8.During work, air is introduced into the preheating of burner hearth interlayer, then from burner, sprays after fully mixing with combustion gas, has effectively improved heat utilization efficiency, makes burning velocity fast, and flame temperature is high.
In addition, because gas nozzle 71 is elongated design, combustion gas is just ejection after gas nozzle stretches into mixing tube one segment distance, separated by a distance with the entrance of pressure-air, avoided the impact of pressure-air stream on combustion gas normal discharge, in addition,, when combustion gas stop supplies, the gaseous mixture of mixing tube all sprays from burner spray orifice; Effectively avoid tempering, safe.
The valve hinges outside of air valve 5 is connected with tooth plate 5, and upper tooth plate 5 is provided with the shifting block 52 that can control motor switch 55 contact actions, and motor switch 55 is electrically connected to air blast 2 and ignition system; Air blast 2 outlets are provided with lateral 23, and lateral 23 is provided with air door in corresponding air valve 5 positions, and this air door outside is provided with lower tooth plate 24 and is connected with upper tooth plate 5 by chain 53; Outer being provided with of upper tooth plate 5 pulled handle 54.When needs are opened stove fire, pull handle 54, motor switch 55 actions, in the time of system igniting, blower fan is also opened, and cooking stove is normally worked, when the open degree of air valve 5 less, cooking stove is when little fiery state, and owing to linking by chain and upper and lower tooth plate between air valve 5 and air door, now air door is in the larger state of open degree, the part air that air blast 2 is produced by boasting is discharged from lateral 23, prevents that cooking stove from putting out fire because wind-force is excessive under little fiery state; When needing big fire, the open degree of air valve is larger, gas flow is large, under interlock effect, air door is corresponding being turned down, and most of air that now air blast 2 is produced by boasting participates in mixed combustion, and the design is simple in structure, easy to operate, sturdy and durable, effectively guaranteed the stable of stove fire, also effectively guaranteed the service life of air blast simultaneously.
In order to make the burning of the mist that enters burner 4 more stable, fry stove supervisor 7 and be provided with two-way, corresponding, mixing tube 8 is also provided with two-way, and warm-air pipe 22 is provided with two-way branch and enters in corresponding mixing duct at its end.
Further; the front portion of frying stove supervisor 7 is provided with magnetic valve 72; magnetic valve 72 is electrically connected to preventing dry combustion holding circuit; preventing dry combustion holding circuit can be infrared induction device, manual overvide; pressure control device etc.; its objective is that induction installation feeds back to holding circuit by information after pan leaves burner hearth, thereby realize, automatically close down combustion gas.
The foregoing is only preferential embodiment of the present invention, as long as within the technical scheme that realizes the object of the invention with basic identical means all belongs to protection scope of the present invention.
