Abstract

The utility model relates to a burner of a gas kitchen range, which comprises a barrel connected with an air pipe. The center of the barrel is provided with an ignition bowl composed of an ignition cover at the upper part of the ignition bowl, discharge holes installed at the lateral part of the ignition bowl, and a heater which is input by a gas pipe and is arranged in the center of the ignition bowl. An air passage cycle, the diameter of which is similar to that of the ignition bowl, is arranged between the barrel of the ignition bowl and the ignition cover. A nick is opened on a fan shroud, and an everlasting fire device is arranged in the nick. The utility model is a safe and reliable burner of a gas kitchen range and can guarantee that the everlasting fire is difficult to quench. The utility model can ignite the kitchen range in time and the combustion efficiency is high.

Description

Burner for gas stove

The utility model relates to the kitchen range burner, especially blowing type gas kitchen range burner.

The blowing type gas kitchen range is food and drink, dining room, hotel kitchen range, is fuel with artificial coal gas, liquefied petroleum gas, natural gas etc., adopts air blast oxygenation and combustion gas mixing, thereby improves efficiency of combustion.Burner is again the most important parts of gas-cooker.Existing burner for gas stove comprises the cylindrical shell that inserts airduct, the central authorities of cylindrical shell are provided with fire bowel, comprise that the ignition cover on fire bowel top, the sidepiece of fire bowel are provided with the wind hole, the central authorities of fire bowel are imported by Gas Pipe, the combustion gas mixing after-combustion that draw at wind and fire bowel center.But the air blast tolerance of existing burner and the ratio deficiency of combustion gas, the design of part-structure is unreasonable, cause firepower not strong, the thermal efficiency is low, expend shortcomings such as fuel, ever-burning flame device in original burner be the wind comes from outward easily or inner air blast is blown out, and brings danger and inconvenience for the use of blowing type gas kitchen range.In addition, through test shows, existing burner for gas stove produces carbon monoxide all greater than 0.2% when burning, and shows that burning is not enough, and burner exists obvious not enough.

The purpose of this utility model is: provide a kind of safe and reliable burner for gas stove, the ever-burning flame device that especially be provided with safely, is difficult for extinguishing; Improve the thermal efficiency of burner, reduce the content of carbon monoxide simultaneously.

The purpose of this utility model is achieved in that a kind of burner for gas stove, comprise the cylindrical shell that inserts airduct, the central authorities of cylindrical shell are provided with fire bowel, comprise that the ignition cover on fire bowel top, the sidepiece of fire bowel are provided with many vents, the central authorities of fire bowel are provided with the heater of Gas Pipe input, it is characterized in that being provided with the diameter wind channel ring close, on wind loop, offer breach, in breach, be provided with the ever-burning flame device with the fire bowel diameter in the centre that fire bowel cylindrical shell and ignition are covered.

Further improvement of the utility model is: the wind hole that the sidepiece of fire bowel is provided with becomes the 1-12 degree with the vertical direction of fire bowel wall, be that this hole is not the center of the accurate fire bowel in opposite, but an inclined to one side side at the bowl center, all inclined to one side homonymy of each wind hole angulation at the center.Airduct inserts from the tangential direction of cylindrical shell, forms rotation wind in cylindrical shell.The whirlwind direction of rotation is not directly injection from the wind hole.

Characteristics of the present utility model are: this is a kind of safe and reliable burner for gas stove, can guarantee that ever-burning flame is difficult for extinguishing, and in time lights kitchen range; The efficiency of combustion height generally can improve 5-10%, and the content of carbon monoxide reduces greatly in the waste gas, generally can drop to below 0.02%.And simple to operation, long service life.

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the plan structure schematic diagram of the utility model burner

Fig. 2 is the A-A cutaway view of Fig. 1

Fig. 3 is a fire bowel wind orifice angle distribution schematic diagram among Fig. 1

As shown in Figure 1, 2, burner for gas stove comprises the cylindrical shell 2 that inserts airduct 13 from sidepiece, and cylindrical shell is connected with cooking stove through flange 1 usefulness bolt or alternate manner.Cylindrical shell 2 is the cylindrical tube chamber, and its central authorities are provided with fire bowel 11, and fire bowel is the concavity bowl shaped container, and diameter is less than cylindrical shell, and fire bowel upper and lower and cylindrical shell seal, the uniform air-out aperture of bowl wall.Fire bowel top is provided with the ignition cover 3 that refractory material is made, and the outside of ignition cover 3 is made by heat-resisting cast iron.The central authorities of fire bowel are provided with the Gas Pipe 9 of drawing the end of from, the fire bowel cylindrical shell is provided with the diameter ever-burning flame wind channel ring 10 close with the fire bowel diameter with the centre of ignition cover, on wind channel ring, offer breach 10-1, in breach, be provided with the ever-burning flame device, promptly comprise gas spray head 5 and the ever-burning flame nozzle 4 of introducing ever-burning flame, finish the setting of ever-burning flame.Heater 7 is hollow circular cylinders among Fig. 2, cover on gas inlet pipe, and top closure, Qi Bishang offers a plurality of gas outlets hole 7-1.Heater 7 and height flush with fire bowel.14 is valve pull bar on the airduct, is used to control the size of air quantity, and it is incendivity that the combustion gas mixing of drawing from the air-out and the fire bowel center of fire bowel wall is lighted through ever-burning flame.And quantity-adjustable and flame size.Fire bowel and heater can be cast iron or other heat-resisting alloy is made, and generally makes with the alloy that is rich in nickel and tungsten, chromium, and the multiple commercial trade mark is arranged, can anti-1200 ℃ high temperature.And wind channel ring is also made for heat-resisting alloy, and certain thickness is arranged.

As shown in figures 1 and 3, the wind hole that the sidepiece of fire bowel is provided with becomes the 3-9 degree for well with the vertical direction of fire bowel wall, for example 5 degree or 7 degree.Be the center of this hole and non-aligned fire bowel, but an inclined to one side side at the bowl center, all inclined to one side homonymy of each wind hole angulation at the center.Airduct 13 inserts from the tangential direction of cylindrical shell 2, and the tangential direction of airduct and airduct acutangulate in fire bowel incision place wind hole 15, has so both formed rotation wind in cylindrical shell, and the whirlwind direction of rotation is not directly injection from the wind hole.
