Abstract

The utility model discloses a burner for gas cooker, comprising a toroidal burning chamber with more than a circle of burner ports, an inner circle duct, an outer circle duct, an air inlet pipe, and a gas burner. The center of the burner has a central burning chamber, a central air inlet pipe and a central burner. The burner port of the central burning chamber is a firn-jet head, whose inner diameter is similar to the central air inlet pipe. The central firn-jet head has a very strong central flame when igniting. The utility model is very suitable for cooking vegetables, which can be used in the household gas range and the gas range of the hotel and the dining room. The utility model can use the natural gas, the manufactured gas and the liquefied petroleum gas, etc., which has high thermal efficiency.

Description

Burner for gas cooker

The utility model relates to the burner that a kind of Chinese meal gas range is used.

Chinese meal burner for gas stove commonly used generally all adopts the version of two circles or three circle apertures, air is advanced in center and outer ring, thereby in use, low and the temperature height all around of the central temperature that has a pot, the phenomenon of " pot limit Jiao's do not boiled in the center " can not satisfy instructions for use during particularly with spherical pot of cooking.

The utility model purpose is the structure that proposes the strong especially burner for gas stove of a kind of center firepower.

This burner for gas stove comprises that combustion chamber, the both sides, combustion chamber of an annular have an inner ring air channel to link to each other with an air inlet pipe with air channel, an outer ring, toroidal combustion chamber, one jet for gas is arranged on the air inlet pipe, toroidal combustion chamber cover the above burner port of a circle, the center of burner also has a central combustion chamber and central intake pipe that links to each other with it and central nozzle, and the burner port of central combustion chamber is the firn-jet head that an internal diameter and central intake pipe are close.

When this burner is lighted, on the burner port of toroidal combustion chamber, have the circle flame, one flame of centre is arranged on the firn-jet head of center, because from then on coal gas one air Mixture of coming from central intake pipe all sprays the firn-jet head, thereby the intensity height of flame, burning is directly sprayed center, the bottom of a pan fully, is specially adapted to cooking.At gas pressure hour, though flame slightly reduces, because air-flow concentrates, thereby the center firepower is still bigger, and can not cause tempering.

Accompanying drawing 1 is the structural representation of this burner.Accompanying drawing 2 is the vertical view of burner.

Introduce the embodiment of this burner in detail below in conjunction with accompanying drawing.

As shown in drawings, (1) central combustion chamber among the figure, (2) firn-jet head, (3) center ventilation chamber cap, (4) divide burner, (5) pot frame, (6) pot ring support, (7) air channel, outer ring, (8) annular firing chamber cap, (9) toroidal combustion chamber, (10) inner ring air channel, (11) air inlet pipe, (12) air door, (13) nozzle, (14) central intake pipe, (15) central nozzle, (16) center air door, (17) annular firing mouth, (18) center air-exchanging chamber, (19) inner ring burner port, (20) outer ring burner port, (21) outer ring air inlet, (22) inner ring air inlet.

Inside and outside two circle burner ports (19), (20) are arranged on the annular firing chamber cap (8) among the figure, the diameter in hole is generally 4～5 millimeters, and the air in inner ring air channel (10) and air channel, outer ring (7) is to suck from several air inlets (21) of bottom, air channel, (22).Firn-jet head (2) is in the center of burner, faces central intake pipe, thus from the coal gas-air mist that central intake pipe is come in fling and on, resistance is minimum, and enough big jet power is also arranged when gas pressure is very little.

In order further to increase the strength of flame of centre, and eliminate tempering phenomenon fully, improve efficiency of combustion, center ventilation chamber cap (3) in an annular of the outside of firn-jet head (2) cover, form the annular firing mouth (17) of a center air-exchanging chamber (18) and a slit-shaped between this center ventilation chamber cap and the center firn-jet head (2), the bottom of center air-exchanging chamber relies on several holes to be connected with central combustion chamber (1).

For heat-insulating property and the uniform performance of flame of strengthening burner, can open some less branch burners equably except over against operator's one side on the edge of doing the pot frame (5) of an annular, pot frame around the burner.

This burner can be made combination shape, particularly firn-jet head, center ventilation chamber cap, and the consumable accessorys such as annular firing chamber cap above only need being shelved on simply, are convenient to mounting or dismounting, keep in repair and are changed. A tungsten net can be put in the burner port top, plays the effect of low baking temperature, temperature fire or heating. As long as change different nozzles, this burner just can use the various gases such as natural gas, artificial coal gas and liquefied petroleum gas, and the thermal efficiency is reaching more than 26%. This burner can be used on the household gas cooker, on the gas range that also can be used for the dining room of machine-operated hostel, restaurant, hotel, industrial and mining enterprises using.

Claims

1, a kind of gas burner, comprise the combustion chamber (9) of an annular, annular inner ring air channel (10), air channel, outer ring (7), the air inlet pipe (11) that links to each other with toroidal combustion chamber and the nozzle (13) of both sides, combustion chamber, the above burner port of one circle is arranged on the lid of toroidal combustion chamber (8), the center that it is characterized in that this burner also has a central combustion chamber (1) to reach central intake pipe (14) and the central nozzle (15) that links to each other with central combustion chamber, and the burner port of central combustion chamber is the firn-jet head (2) that an internal diameter and central intake pipe are close.

2, burner as claimed in claim 1, it is characterized in that also being with on the described firn-jet head (2) the center ventilation chamber cap (3) of an annular, form the annular firing mouth (17) of a center air-exchanging chamber (18) and a slit-shaped between this center ventilation chamber cap and the center firn-jet head (2), the bottom of center air-exchanging chamber (18) relies on several holes to be connected with central combustion chamber.
