The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, present embodiment comprises burner 1, blower fan 2, blender 3, controller 4, gas ratio valve 5.
Burner 1 is provided with air admission hole 11 and venthole 12, and blower fan 2 is provided with air inlet 21 and air outlet 22.
Gas ratio valve 5 is provided with into gas port 51 and goes out gas port 52, the gas port 33 that goes out to mix of blender 3 is communicated with air admission hole 11 on the burner 1, the air outlet 22 that goes out gas port 52, blower fan 2 of gas ratio valve 5 is communicated with blender 3, gas ratio valve 5, blower fan 2 electrically connects with controller 4, and gas ratio valve 5, blower fan 2 make under the control of controller 4 that the ratio of combustion gas and air is the ratio that reaches completing combustion in the gaseous mixture.
Controller 4 stores the combustion gas of energy completing combustion and the ratio value of air, and this ratio value can be the ratio value of a kind of combustion gas and air, also can be the different proportion value of different combustion gas and air.Standard oil liquefied gas (C for example 3H 8: 75%, C 4H 10: 25%) ratio with air completing combustion needs can be 1:26; Standard natural gas (CH for example 4: 100%) ratio with air completing combustion needs can be 1:10.Gas-cooker on the market can only use a kind of combustion gas at present, when changing the combustion gas use, then must transform or change gas-cooker to gas-cooker.And the gas-cooker among the present invention can general multiple combustion gas, when the combustion gas of input not simultaneously, 4 need of controller call corresponding preset ratio value can make the combustion gas of input and air reach can completing combustion ratio, do not need gas-cooker is transformed.
In the entering gas port 51 places a combustion gas inductive probe can be installed of gas ratio valve 5, combustion gas inductive probe and controller 4 electrically connect.This combustion gas inductive probe can judge which kind of combustion gas the combustion gas of input is, be liquefied gas or natural gas etc., then signal is passed to controller 4, controller 4 calls different preset ratio values according to the difference of gas kind, different ratio value correspondences the rotating speed of different blower fan 2 and the aperture of gas ratio valve 5, controller 4 is adjusted the aperture of rotating speed and the gas ratio valve 5 of blower fan 2 by adjusting curtage, thereby makes the ratio of combustion gas and air satisfy the needs of completing combustion.
Can be provided with into air scoop 31, fuel gas inlet 32 on the blender 3, go out to mix gas port 33, advance air scoop 31 and be communicated with the air outlet 22 of blower fan 2, fuel gas inlet 32 is communicated with the gas port 52 that goes out of gas ratio valve 5.Enter the position of air scoop 31, fuel gas inlet 32 for being connected with blower fan 2, gas ratio valve 5 on the blender 3, advancing air scoop 31, fuel gas inlet 32 can also can unite two into one for 2 holes independently.When advance air scoop 31, when fuel gas inlet 32 is a hole, combustion gas and air enter in the blender 3 in a place, can be conducive to promote mixed effect.
Blender 3 comprises blender upper casing 34, blender lower casing 35, and blender upper casing 34 covers at blender lower casing 35 and connects into an integral body.When blender 3 is divided into 2 parts and makes, simplified manufacturing technique and cost effectively.After blender upper casing 34, blender lower casing 35 are made, only need the two tight connection can be formed complete blender 3 by multiple connected mode of the prior art.
Blender upper casing 34 can be provided with upper stop piece 341, and the purpose that upper stop piece 341 is set is to increase resistance and the stroke of mist in blender 3, with the effect of further lifting mixing.
Through hole can be provided with on the upper stop piece 341, to change the shunt paths of mist, mixed effect can be further promoted.
Blender lower casing 35 can be provided with lower stop piece 351, also can be provided with through hole on the lower stop piece 351, and its purpose also is in order further to promote mixed effect.
Upper stop piece 341 and lower stop piece 351 show dislocation arranges (being crisscross arranged), after blender upper casing 34 and blender lower casing 35 connect into an integral body, forms the hybrid channel 36 of continuous the confession combustion gas of " U " type and air mixing at the inner chamber of blender 3.
During household gas range work, combustion gas is advanced gas port 51 and is flowed into from gas ratio valve 5, enter the blender 3 from going out gas port 52 fuel gas inlet 32 of flowing through, air enters (the required air capacity of combustion gas completing combustion is all provided by blower fan 2) from the air inlet 21 on the blower fan 2, enters the blender 3 through advancing air scoop 31 from air outlet 22.
The combustion gas and the air that enter blender 3 mix in hybrid channel 36, and upper stop piece 341 and lower stop piece 351 when gaseous mixture is flowed multiple impact take place in hybrid channel 36, make its mixing more even.
Combustion gas and air mix the back and flow out from going out to mix gas port 33 in blender 3, flow into the burner 1, at last from venthole 12 blow-off point fire burns from air admission hole 11 then.
Hybrid channel 36 has effectively increased the mixed path of mist, make combustion gas and air incorporation time longer, and then make combustion gas and air mix more fully, promoted mixed effect preferably, be conducive to the completing combustion of combustion gas, so the present invention can make combustion gas and air mix in proportion effectively, and then make fuel gas buring abundant, and then avoid occurring the insufficient phenomenon of burning such as Huang Yan, the thermal efficiency that promotes gas-cooker there is positive role.
