Description
Technical field
The present invention relates to a kind of burners, more particularly, to a kind of cooker burner.
Background technique
The primary air ratio of existing air suspended type cooker burner is generally 0.4-0.7, and the air of premix is not achieved completely
The air capacity that burner needs, in addition various factors, needs certain auxiliary air coefficient to supplement, also, in order to reduce CO's
Discharge, auxiliary air coefficient supplement should as far as possible sufficiently.Currently, the mode of cooker burner supplement air is varied, one
As have the mode of side air inlet and lower air inlet, the mode of side air inlet opens side air admission mouth in the side of mixing chamber, and outside air is logical
It crosses the side air admission mouth and carries out auxiliary air supplement, the mode of lower air inlet opens lower air inlet in pedestal pedestal, below kitchen range
Air carries out auxiliary air supplement by the lower air inlet.Wherein, although the mode of lower air inlet has intake resistance small, air inflow
Still the problem of there are many problems in big advantage, still, the burner of existing lower air inlet, firstly, there are hardly possible cleanings, because overflowing
Liquid is easy to flow directly to the inside of kitchen range or even cabinet interior, keeps kitchen range and cabinet not easy to clean, and have discharge inside kitchen range
After stay in some potential safety problems；Secondly as the burner aperture of lower air inlet is all bigger, auxiliary air is directly entered inner ring
And outer ring channel, air supplement is inaccurate, and auxiliary air excessively will lead to efficiency decline instead.In conclusion needing to existing
The lower air inlet structure of cooker burner is further improved.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to above-mentioned state of the art, a kind of secondary sky of lower air inlet is provided
The good cooker burner of gas supplementary result.
The technical scheme of the invention to solve the technical problem is: the cooker burner, including pedestal, mixed gas
Room, interior ring fire cover and external ring fire cover, the mixing chamber are set to above pedestal and have circular passage, the interior ring fire cover and outer ring
Fire cover is set to above mixing chamber and is located at the inside and outside two sides of the circular passage, the bottom of the pedestal have with it is described
Longitudinal auxiliary air hole that circular passage is connected, it is characterised in that: further include having flow distribution plate, the upper cap of the flow distribution plate is set
There are outer ring air inlet gap on the external ring fire cover and between external ring fire cover, the lower part formation of the flow distribution plate is protruded into described
The auxiliary air distributary division of outer passage and inner channel, the secondary sky in longitudinal direction are separated into circular passage and by circular passage
Stomata, which is connected by outer passage with outer ring air inlet gap, constitutes outer ring secondary-air passage, the auxiliary air distributary division
There are inner ring air inlet gap between interior ring fire cover, the longitudinal direction auxiliary air hole passes through inner channel and inner ring air inlet gap phase
It is connected to and constitutes inner ring secondary-air passage.
Auxiliary air distributary division can have a variety of structures, it is preferable that the auxiliary air distributary division include annular outer wall,
Annular inner wall and the bottom plate between annular outer wall and annular inner wall, between the annular outer wall and the lateral wall of circular passage
The outer passage is formed, forms the inner channel between the annular inner wall and the inner sidewall of circular passage.Using
After above structure, what a spill can be formed on the bottom of flow distribution plate holds liquid zone, can accept the discharge and impurity of a part.
In order to play preferably guiding role to the inner ring auxiliary air after shunting, the annular inner wall has from bottom to top
The vertical wall that the inclined wall extended in the diagonal and the top vertical from inclined wall upwardly extend, the vertical wall and the interior ring fire
There are the inner ring air inlet gaps between the lateral wall of lid.After the guiding of inclined wall, inner ring auxiliary air can more collect
It is added in interior ring fire middlely, supplementary result is more preferable.
In order to keep outer ring auxiliary air supplementary result more preferable, the top of the flow distribution plate from the top of the annular outer wall to
Upper extend is in loudspeaker oral area, and the shape of the loudspeaker oral area is adapted with the shape of the external ring fire cover upper surface, also, described
The outer ring air inlet gap is formed between loudspeaker oral area and external ring fire cover.
Discharge flows on external ring fire cover in order to prevent, and the outside portion of the loudspeaker oral area has to the horizontal-extending ring in periphery
Shape flange, also, the outer diameter of the annular flange is greater than the outer diameter of the external ring fire cover.
For the ease of fixed and positioned flow distribution plate, limiting slot is formed on the upper surface of the external ring fire cover, described
The bottom of annular flange forms the spacing block set matched with the limiting slot.
In order to preferably be positioned to flow distribution plate, the limiting slot at least there are three and along external ring fire cover it is circumferentially-spaced
Even distribution, accordingly, the spacing block set at least there are three and be uniformly distributed to interval in the circle along the annular flange.
In order to keep inner ring auxiliary air supplementary result more preferable, it is provided with and the circular passage phase in the side of the mixing chamber
The radial second airport of connection is provided with corresponding with radial second airport logical on the annular outer wall of the flow distribution plate
Hole, the through-hole are radially penetrated through with corresponding radial second airport.In this way, auxiliary air is by radial second airport and leads to
Hole can add to interior ring fire, keep interior ring fire burning more abundant, also, after through-hole and radial second airport radial communication,
The discharge of acceptable water conservancy diversion a part outward, conducive to the cleaning for keeping burner internal.
Further preferably, the radial second airport at least there are three and along the mixing chamber it is circumferentially-spaced
Even distribution, accordingly, the through-hole at least there are three and be uniformly distributed along the circumferentially-spaced of the annular outer wall.
Compared with the prior art, the advantages of the present invention are as follows: after the cooker burner is by setting flow distribution plate, by mixing chamber
Circular passage be separated into outer passage and inner channel, longitudinal auxiliary air hole on pedestal by outer passage and outer ring into
Gas gap is connected and constitutes outer ring secondary-air passage, and longitudinal auxiliary air hole passes through inner channel and inner ring air inlet gap phase
It is connected to and constitutes inner ring secondary-air passage, so that the auxiliary air in longitudinal auxiliary air hole shunts in rear portion adds to
Ring fire, another part add to outer ring fire, and auxiliary air supplementary result is good, so that burner combustion is more abundant.
