Description

Energy-saving oil gas dual-purpose stove head

Technical field

The utility model provides the assembly on a kind of commercial oven tool, especially a kind of burner.

Background technology

Burner on the oil-gas two-way stove and accessory that commercial units such as dining room, restaurant, hotel use when being fuel with fuel oil such as diesel oil, adopts direct combustion system.Promptly directly light the fuel oil that flows out from oil inlet pipe, fuel oil is not handled through atomizing, and therefore, fuel oil and Air mixing are not good enough, and it is insufficient to burn, and efficiency of combustion is low, and power consumption is high.Flame temperature is low, and rubicundity, and produce exhaust emission influence the healthy protection with environment of cook, and the fuel oil smell is also scurried in the food of being processed easily.When this burner uses on stove and accessory, need the bigger blower fan of special installation power, noise is also just bigger.Because of fuel oil is handled without atomizing, thus ignition difficulties, need elder generation after the fuel Heating, with kindling material it is lighted again.Be that fuel also exists the inadequate problem of burning with combustion gas such as coal gas, liquefied gas.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of energy-saving oil gas dual-purpose stove head, to improve the convenience of energy-saving effect and use.

The utility model is to realize like this, energy-saving oil gas dual-purpose stove head, it has the burner shell, the axle bottom of fixing motor is equipped with the impeller of band blade in the burner shell, the burner shell upper is fixed with outer wall of combustion chamber by the outer ring, be fixed with combustion chamber inwall with holes in the outer wall of combustion chamber, the lower end of combustion chamber inwall is fixed with combustion chamber soleplate, escape pipe is arranged below the combustion chamber soleplate, venthole is arranged on the escape pipe, the top of axle is fixed with block, block is fixed with rotating cylinder outward, have the chimney fan lower end to be fixed on the base plate of combustion chamber soleplate below in the rotating cylinder, the oil-out of oil inlet pipe is positioned at the top of chimney fan, on the top board of burner shell upper exhaust vent is arranged.

Adopt the energy-saving oil gas dual-purpose stove head of said structure, when using fuel oil as fuel, atomizing effect is good, sufficient combustion, and flame is blue during burning, flame temperature height, so efficiency of combustion height, good energy-conserving effect.Blower fan, air door and burner integrator, simple in structure, easy for installation.Fuel oil and air good mixing have passed through sufficient atomizing, and therefore igniting also is very easy to.When being fuel with the combustion gas, it is also very abundant to burn.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and operation principle.

As shown in drawings, the energy-saving oil gas dual-purpose stove head of the utility model, it has burner shell (11), axle (13) bottom of fixing motor (12) is equipped with the impeller (24) of band blade (25) in the burner shell, the burner shell upper is fixed with outer wall of combustion chamber (5) by outer ring (8), be fixed with combustion chamber inwall (3) with holes in the outer wall of combustion chamber, the lower end of combustion chamber inwall is fixed with combustion chamber soleplate (18), escape pipe (19) is arranged below the combustion chamber soleplate, venthole is arranged on the escape pipe, the top of axle (13) is fixed with block (1), block is fixed with rotating cylinder (2) outward, have chimney fan (17) lower end to be fixed on the base plate (21) of combustion chamber soleplate below in the rotating cylinder, the oil-out of oil inlet pipe (7) is positioned at the top of chimney fan, and the top board of burner shell upper has exhaust vent on (22).

Another impeller (14) of band blade (15) also is installed in the bottom of described axle (13), has the deep bead (26) of being with blade (27) of keeping out the wind to be fixed on the bottom of burner shell (11) between two impellers, there is fresh air inlet in deep bead central authorities.The oil-gas two-way burner of this structure, wind-force is bigger.The existence of deep bead produces tempering phenomenon in the time of can preventing to place cooker on burner.

Air door plate (10) is installed under the exhaust vent of described top board (22), is fixed with tooth bar (33) on the air door plate, tooth bar and air door adjusting lever (30) are gone up fixing gear (34) and are meshed together.This is a kind of oil-gas two-way burner that can adjust the air quantity size.Air door adjusting lever outermost end is installed on the stove and accessory, can be fixed with knob above it.Rotate the air door adjusting lever, can pass through gear, the rotation of rack drives air door plate, thereby change the size of air door, the size of promptly regulating intake.

Be fixed with spark plug (31) on described outer wall of combustion chamber (5) and combustion chamber inwall (3), the ignitor on the spark plug (32) is positioned at outside the inwall of combustion chamber.Ignitor links to each other with firing circuit.During firing circuit work, produce electric spark between two ignitors, fuel oil can be lighted.

Be fixed with burner bottom enclosure (16) in described burner shell (11) lower end, there is fresh air inlet in burner bottom enclosure central authorities.Can further improve the air intake effect like this.

Between combustion chamber soleplate (18) and base plate (21), be fixed with support bar (20).Can there be blade (4) the rotating cylinder lower end.Impeller (24), (14) are fixed on the axle (13) by axle sleeve (23) and another axle sleeve (28) respectively.Air door plate is installed on the top board (22) by pole (9).On the combustion chamber soleplate

During use, the oil-gas two-way burner of the utility model is installed on the stove and accessory, air inlet pipe (29), escape pipe (19) and combustion gas such as coal gas, liquefied gas source are connected, oil inlet pipe communicates with fuel container.During work, motor rotates, and impeller is rotated, and wind enters from the fresh air inlet in the burner bottom enclosure, and the exhaust vent after impeller quickens on air door plate, the top board enters the cavity between base plate (21) and the top board (22).Rise along air duct is inner again, meet with the fuel oil that the oil inlet pipe oil-out sprays on air duct top.The wind fuel oil of promptly carrying under one's arms rises, and runs into block and stops that the back changes direction, and is descending along the cavity between rotating cylinder and the air duct, the cavity when entering base plate and burning between the base plate.Enter the cavity between outer wall of combustion chamber and the combustion chamber inwall then, the hole from the inwall of combustion chamber is microgranular ejection at last, fully mixes with air, thereby obtains good atomizing, can carry out work such as cooking after lighting with kindling material.

When adopting combustion gas to be fuel, combustion gas enters escape pipe (19) through air inlet pipe (29), flows out the hole from escape pipe, enter the cavity between outer wall of combustion chamber and the combustion chamber inwall, spray the hole from the inwall of combustion chamber at last, fully mix, get final product work after lighting with air.Because the oil-gas two-way burner air intake of the utility model is good, so fuel gas buring is also more abundant, also plays energy-saving effect preferably.
