Abstract
An upper air inlet type burner for a gas stove comprises a base, a gas mixing chamber, an outer ring fire cover and an inner ring fire cover. The base is provided with a cavity with an upward opening, the gas mixing chamber is arranged above the base and provided with an annular cavity, and the inner ring fire cover and the outer ring fire cover are arranged on the gas mixing chamber and located on the inner side and the outer side of the annular cavity respectively. The upper air inlet type burner is characterized in that the cavity is isolated from the annular cavity, the side portion of the gas mixing chamber is provided with a primary air hole and a secondary air hole, the primary air hole is communicated with the cavity to form a primary air channel, and the secondary air hole is communicated with the annular cavity to form a secondary air channel. The upper air inlet type burner has the advantages that due to the fact that the cavity of the base is isolated from the annular cavity of the gas mixing chamber, and the primary air hole is formed in the side portion of the gas mixing chamber, primary air supplement can be carried out without arranging a gap between the gas mixing chamber and the base, a panel screw can be hidden below the gas mixing chamber, and the structure of the burner can be simple; in addition, secondary air can be supplemented to the inner ring fire cover through the annular cavity via the secondary air hole, and therefore the inner ring fire combustion efficiency can be improved.
Description
Technical field
The present invention relates to a kind of burner, more particularly, to a kind of upper wind inlet type burner for gas-cooker.
Background technology
At present, have begun to use the burner of Full-upside air inlet type in many gas kitchen ranges, due to full upward air intake
The burner of formula first and second air required in burning is all from the top of stove panel, thus the chassis of gas kitchen ranges can
With hermetically sealed, compared with the burner of traditional lower air inlet structure, the burner of Full-upside air inlet type not only using safer,
And can well solve the problems, such as that switching cupboard door causes kitchen range to stop working.However, the burner of traditional full upward air intake
When primary air is supplemented realized by the gap between mixing chamber and pedestal, the problem thus brought is, mixing chamber with
There is gap between pedestal, after the mounting screw of panel is installed, from combustor external mounting screw can be seen, cause burner
Profile it is not attractive in appearance enough.Also, arrange behind gap between pedestal and mixing chamber, discharge can flow into pedestal by the gap
It is interior, not only bad for the cleaning of burner, and if discharge cannot remove for a long time, influence whether normally making for burner
With.
Chinese utility model such as Patent No. ZL201020579358.1 (Authorization Notice No. is CN2018586642U) is special
Disclosed in profit《A kind of Full-upside air inlet type burner》, the Full-upside air inlet type burner include furnace head base, fire cover seat, center
Fire cover and external ring fire cover, wherein fire cover seat include seat and central gas-supply hole under the fire cover seat of honour, fire cover, under fire cover seat and furnace head base it
Between have primary air air inlet gap, and primary air air inlet gap be located at panel top.And for example Patent No.
Disclosed in the Chinese utility model patent of ZL201120527929.1 (Authorization Notice No. is CN202392799U)《It is completely enterprising
Wind cooker burner》, the stove burner with complete upper air feeding includes the seat of honour and lower seat two parts, and lower seat is used to connect combustion gas, on
Seat is burnt for spraying combustion gas located at lower seat top, once air inlet gap between the seat of honour and lower seat, the seat of honour and under
Induction tunnel and nozzle are provided between seat, nozzle is connected to lower seat and relative with induction tunnel air inlet.It can be seen that, above two goes up completely
Between the burner of air intake is supplemented between gap and the seat of honour and the lower seat that primary air passes through respectively between lower seat and furnace head base
Gap needs to be further improved in structure realizing.
The content of the invention
The technical problem to be solved is for above-mentioned state of the art, there is provided a kind of primary air and secondary
The upper wind inlet type burner for gas-cooker that air is all filled into by the airport on mixing chamber.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：This is used for the upper wind inlet type burner of gas-cooker
Including pedestal, mixing chamber, external ring fire cover and interior ring fire cover, the pedestal has opening up cavity, and the mixing chamber is located at
Pedestal top simultaneously has annular chamber, and the interior ring fire cover and external ring fire cover are located at mixing chamber top and respectively positioned at the annular chamber
Inside and outside both sides, it is characterised in that：The cavity and annular chamber are mutually isolated, are provided with once in the sidepiece of the mixing chamber empty
