Description
Technical field
The utility model relates to field of household appliances, more specifically, relates to a kind of burner of gas-cooker and a kind of gas-cooker comprising this burner.
Background technology
As shown in Figure 1, the combustion gas of outer burner port 221 ' the place discharge of the burner 1 ' of gas-cooker is when burning, and required a part of combustion oxygen derives from the auxiliary air flowed from bottom to top along air duct 8 '.Wherein, oxygen meeting in auxiliary air and combustion gas are reacted and burn, and when the temperature of burning is higher, nitrogen in auxiliary air also can participate in the middle of combustion reaction and generate nitrogen oxide, nitrogen oxide is discharged in air can have a negative impact to environment (being one of factor producing acid rain), be unfavorable for environmental protection, also affect the healthy of consumer simultaneously.Therefore, how to reduce even eliminate nitrogen oxide growing amount, simultaneously also prevention generates CO gas is the current technical problem that need solve.
And solution used in the prior art, be by arranging auxiliary air back-up ring or by reducing air duct 8 ' cross-sectional area, reduce the quantity delivered of auxiliary air bottom air distribution disk, to realize the object reducing formation of nitrogen oxides.But, because the magnitude of recruitment of auxiliary air reduces, the oxygen required for burning can be caused not enough, easily cause incomplete combustion, well could not accomplish the generation preventing carbon monoxide, thus make the content overproof of carbon monoxide in flue gas, can not eliminate and environment and consumer health are had a negative impact.
Utility model content
Analysis background technology can be found out: the transport path of auxiliary air in air duct and how many external burner port place nitrogen oxide of transmission quantity and the growing amount of carbon monoxide number have a great impact, therefore control the growing amount of outer burner port place nitrogen oxide and carbon monoxide by controlling the transport path of auxiliary air in air duct.
The utility model is intended at least to solve one of technical problem existed in prior art.
For this reason, the utility model provides and a kind ofly can reduce the burner of gas-cooker even eliminating nitrogen oxide and carbon monoxide emission, environment protection health, the growing amount of outer burner port place nitrogen oxide and carbon monoxide is reduced better by the conveying track controlling auxiliary air in air duct, to be satisfied with the requirement of environmental protection better, thus reduce the harm healthy to consumer.
For achieving the above object, the embodiment of the utility model aspect provides a kind of burner of gas-cooker, and comprising: outer shroud air flue, its top has outer burner port; Inner ring air flue, is positioned at the inner side of described outer shroud air flue and forms the air duct of annular separately with described outer shroud air flue, and the top of described inner ring air flue has internal combustion hole burning; With back-up ring (arranging closer to outer burner port), between described outer shroud air flue and described inner ring air flue, and outside it with the middle part of the madial wall of described outer shroud air flue or top is connected, the lateral wall of inner edge and described inner ring air flue separately.
The burner of the gas-cooker that the utility model provides, the flow direction of auxiliary air in air duct is changed by the middle part or top that back-up ring are arranged on the madial wall of outer shroud air flue, make the flow direction of auxiliary air in air duct away from the combustion flame at outer burner port place, to prevent auxiliary air under the ejector action and buoyancy lift effect of flame, too much is supplied in the middle of flame, and the problem that the growing amount of nitrogen oxide is increased occurs.
Therefore: the burner of the gas-cooker that the utility model provides can reduce the growing amount of nitrogen oxide time burning in combustion gas combustion outer hole place, prevent the content overproof of nitrogen oxides in effluent, effectively avoid consumer when using gas-cooker, suck too much pernicious gas, meet environmental protection, healthy designing requirement better.
