Abstract
The invention discloses a low-noise high-firepower combustor which comprises a cylindrical outer shell and a cylindrical inner shell sleeved in the outer shell. The top of the outer shell and the top of the inner shell are in closed connection, an interlayer cavity is formed between the outer shell and the inner shell, an air inlet is formed in the bottom of the outer shell, the bottom of the inner shell is sealed, an inner cavity of the inner shell is provided with at least two or more steps gradually enlarged from bottom to top, and the lengthwise side wall of each step is provided with widespread vent holes. Airflow blown out of a bottom cavity is ejected outwards from the space corresponding to the bottom cavity, airflow blown out of each cavity above the bottom cavity can be ejected outwards from the enlarged space corresponding to the cavity, collision and pushing of the airflow of the steps at different heights are much weakened as compared with traditional collision and pushing, turbulence can be effectively reduced, and offset of the ejection force of the airflow ejected out of the combustor from the steps at different heights can also be effectively weakened.
Description
Technical field
The present invention relates to technical field of burner.
Background technology
At some professional culinary gas-cookers such as catering trades, in order to add high flame, air blast often is installed, the burner be connected with blower fan is by shell and the inner casing of tubular, and inner casing is set with in the enclosure, the closed connection between the top of shell and inner casing, form the interlayer cavity between shell and inner casing, the bottom of shell is provided with air intake, the sealed bottom of inner casing, and the sidewall of inner casing offers the passage spread all over.At present, inner casing as the burning use furnace chamber, no matter be the burner of any form, inner casing be all be set as straight-cylindrical.Mix the mode of gas and divide the interior mixed gas of furnace chamber and furnace chamber mixed gas outward, combustion gas is taken over to straight cutting and enter in furnace chamber for mixing gas in furnace chamber.No matter be that a kind of mode, during burning, have gas to be blown into from the passage of interior shell side wall, blow out from the nozzle of inner casing, form flame.Because passage spreads all over the sidewall of inner casing, form the air-flow of differing heights layer, the air-flow of these differing heights layers can collide mutually, forms turbulent flow.During burning, in the straight-cylindrical confined space of inner casing, the space that the air-flow originally blown out from low layer is full of, then blow into high-rise air-flow, the collision between air-flow is stronger, mutually push between air-flow, offset, turbulent flow is strong, causes combustion noise very large, and strong turbulent flow can be offset the dynamics of air-flow from the nozzle ejection, cause flame height inadequate, the firepower shortcoming of gas-cooker.
Summary of the invention
The technical problem to be solved in the present invention is to provide the burner of the blower fan gas-cooker that the low firepower of a kind of noise is strong.
For solving the problems of the technologies described above adopted technical scheme: a kind of noise hangs down the strong burner of firepower, include cylindrical outer casing and tubular inner casing, the inner casing cover in the enclosure, the closed connection between cover top portion and inner casing top, form the interlayer cavity between shell and inner casing, the bottom of shell is provided with air intake, the sealed bottom of inner casing, it is characterized in that: the inner chamber of described inner casing is set as and is from top to bottom step by step at least two-stage that enlarges or above step shape, and the length direction sidewall of every one-level all offers the passage spread all over.
On the basis of the above, the step shape inner chamber of described inner casing is set as three grades, and the quantity of the passage of every one-level increases from top to bottom step by step.
On the basis of the above, the sidewall of described shell is coated with combustion gas and takes over, and the inner that combustion gas is taken over is provided with the cavity ejecting device jet to surrounding between outer casing bottom and inner shell bottom.
On the basis of the above, described ejecting device comprises the cavity that is formed on inner shell bottom, and the sidewall of cavity offers the passage spread all over, and combustion gas is taken over and inserted in cavity.
The beneficial effect that adopts the present invention to bring: the present invention is set as the inner chamber of inner casing to be from top to bottom at least two-stage that enlarges step by step or above step shape, the air-flow that the bottom cavity blows out to should the layer cavity space spray outward, the air-flow that every one-level cavity up blows out all can spray outward from the space to should level enlarging, collision between the air-flow of differing heights level is compared traditional having weakened much with pushing like this, can effectively reduce turbulent phenomenon, and the counteracting of the outer ejection dynamics of past burner between differing heights level air-flow also can effectively be weakened.Therefore, adopt burner of the present invention to contrast traditional burner, not only can effectively reduce combustion noise, and burned flame is high, the firepower of gas-cooker is strong.Combustion gas is abundant with mixing of air, makes the completing combustion of combustion gas energy, can save combustion gas, while turning firepower down, can not stop working, the convenient use.
The accompanying drawing explanation
The structural representation that Fig. 1 is the burner that the low firepower of noise of the present invention is strong.
The specific embodiment
As shown in Figure 1, a kind of noise hangs down the strong burner of firepower, include cylindrical outer casing 1 and tubular inner casing 2, inner casing 2 is enclosed within shell 1, the closed connection between shell 1 top and inner casing 2 tops, forms the interlayer cavity between shell 1 and inner casing 2, the bottom of shell 1 is provided with air intake 11, bottom 21 sealing of inner casing 2, the inner chamber of inner casing 2 is set as and is from top to bottom at least two-stage that enlarges step by step or above step shape, and the length direction sidewall of every one-level all offers the passage 22 spread all over.Concrete, the step shape inner chamber of described inner casing 2 is set as three grades, and the quantity of the passage 22 of every one-level increases from top to bottom step by step.
In the present embodiment, the sidewall of described shell 1 is coated with combustion gas and takes over 3, and the inner of combustion gas adapter 3 is provided with the cavity ejecting device jet to surrounding between shell 1 bottom and inner casing 2 bottoms.Concrete, described ejecting device comprises the cavity 23 that is formed on inner casing 2 bottoms, and the sidewall of cavity 23 offers the passage 22 spread all over, and combustion gas is taken over 3 and is inserted in cavity 23.Certainly, ejecting device also can adopt other common Annular Nozzle etc. as shower nozzle, is responsible for combustion gas the cavity between shell 1 bottom and inner casing 2 bottoms jet to surrounding, reaches and the well-mixed purpose of air.
Air is sent into from the air intake from shell 1 bottom by blower fan, combustion gas is taken over 3 from combustion gas and is sent into cavity 23, passage 22 ejection from spreading over cavity 23 sidewalls again, after the interlayer cavity between shell 1 and inner casing 2 mixes, enter the furnace chamber burning through the passage 22 of inner casing 2 sidewalls.In fact, also can, without combustion gas adapter and ejecting device are arranged on burner, combustion gas can be sent into from the air intake of shell 1 bottom in company with air.
