Description

Burner fire lid for gas-cooker
Technical field
The present invention relates to gas-cooker field, refer specifically to a kind of burner fire lid for gas-cooker.
Background technology
Chinese utility model patent ZL201520202421.2 discloses " burner of a kind of household gas range ", and it includes Fire cover, is provided with fuel chamber in described fire cover, described fire cover lateral wall is provided with annular recess.Described recess is provided with main fire hole and position Stable flame hole above main fire hole, described stable flame hole is positioned at the described recess top near the region at fire cover center, and described Stable flame hole is horizontally disposed with or described stable flame hole is internal to the outside downward-sloping setting of described fire cover by described fire cover.This practicality is new The burner of the household gas range described in type, main fire hole and stable flame hole be hidden in recess, and the discharge in cooking process is by fire cover The flange of end blocks, and fluid is not easily accessible and blocks main fire hole, and is horizontally disposed with due to stable flame hole or described stable flame hole is by institute State fire cover internal to the outside downward-sloping setting of described fire cover, be avoided that the bottom of a pan fluid enters and blocks stable flame hole.
Summary of the invention
The technical problem to be solved is that the present situation for prior art provides one can be prevented effectively from tempering The burner fire lid for gas-cooker.
The present invention solves the technical scheme that above-mentioned technical problem used: this is used for the burner fire lid of gas-cooker, bag Include annular body, the annular top surface of described body with downwardly extend from the inside edge of this annular top surface, outer ledge respectively Form mixing chamber between internal ring wall, external annulus, described body is interval with the main fire hole of the described mixing chamber of multiple connection;
It is characterized in that:
The annular top surface of described mixing chamber has internal ring portion and outer portion two parts;The top of described internal ring portion exceeds described The top of outer portion;
Each described main fire hole is circumferentially in described outer portion;
The stable flame hole that multiple and described mixing chamber is connected, going out of described stable flame hole is circumferentially had on described internal ring portion Mouth is towards described main fire hole, and the outlet of described stable flame hole is positioned at the lower section of described main fire hole outlet.
Preferably, the axis of described stable flame hole is 90~150 ° of angles with the axis of described main fire hole.Steady flame in the program Flame is while stablizing main fire control flame, and two bundle flames can be good at convergeing to together, improves the efficiency of heating surface.
Preferably, the outlet of described main fire hole can be towards the inner side of described body, and the outlet of described stable flame hole is towards institute State the outside of body, and the axis of described main fire hole is from bottom to top to the centerline dip of described body.The program can make Stable flame hole blow-through is to the root of main fire control flame, while obtaining the most steady flame effect, and stable flame hole flame and main fire control fire Flame merges, it is possible to improve the thermal efficiency further.
In order to obtain good steady flame effect, described internal ring portion towards described outer portion wall can in from inside to outside to The ring plain of upper inclination or ring-type cambered surface.This structure makes the air inlet of stable flame hole more smooth and easy, thus ensures that stable flame hole flame is steady Fixed good burning.
In above-mentioned each scheme, each described stable flame hole and each described main fire hole can be arranged with one_to_one corresponding, preferably, each described Stable flame hole is uniform staggered with successively with each described main fire hole.This structure further improves steady flame effect.
For being further ensured that stable flame hole and the stability of main fire hole burning, described mixing chamber is directly connecting with described stable flame hole Logical position can be cross section be the first annular air cavity of inverted " V " type, described mixing chamber is directly connecting with described main fire hole Position be cross section be the second annular air cavity of inverted " V " type.This structure can not only ensure the smooth and easy of air-flow, and the first air cavity energy Enough spaces providing buffering when airflow fluctuation, it is to avoid the airflow fluctuation impact to main fire hole flame, further avoid tempering Phenomenon.
Compared with prior art, the burner fire lid for gas-cooker provided by the present invention, stable flame hole to main fire hole, Flame in stable flame hole is to the root-burn to main fire hole flame, the problem having eradicated tempering, and can merge with main flame, Improve the efficiency of heating surface.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is the schematic perspective view of embodiment of the present invention different angles;
Fig. 3 is the longitudinal sectional view (ladder cuts open) of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, this burner fire lid being used for gas-cooker includes:
Body 1, for circulus, the annular top surface 23 of body 1 with respectively from inside edge, the outside of this annular top surface 23 Mixing chamber 2 is formed between internal ring wall 21 that edge downwardly extends, external annulus 22;The medial surface 21 of mixing chamber 2 includes being positioned at lower section Vertical endless inner wall 21a and be inclined upwardly from inside to outside along the upper edge of endless inner wall 21a and connect the upper end of internal ring portion 4 Circumferentia 21b of edge;The lateral surface 22 of mixing chamber is parallel to endless inner wall 21a.
The end face 23 of mixing chamber 2 is provided with internal ring portion 4 and outer portion 5.
Internal ring wall 4 is arranged oppositely with external annulus 5;Wherein outer portion 5 from bottom to top, from outside to inside towards the center of body 1 Line tilts;Internal ring portion 4 the most from bottom to top, the centerline dip of body 1 the most dorsad.
It is evenly equipped with the main fire hole 3 of multiple connection mixing chamber 2 in outer portion 5, internal ring portion 4 is evenly equipped with multiple connection mixing chamber The stable flame hole 6 of 2.The main centrage of fire hole 3 and the centrage of stable flame hole are 140 ° of angles.
Mixing chamber 2 at the position directly connected with stable flame hole 6 be cross section be the first annular air cavity 24 of inverted " V " type, mixed gas Room 2 at the position directly connected with main fire hole 3 be cross section be the second annular air cavity 25 of inverted " V " type.
The outlet of stable flame hole 6 is positioned at the most close internal ring portion 4 in lower section and the intersection of outer portion 5 of the outlet of main fire hole 3, with The flame making stable flame hole blows to the root of main fire hole flame.
Each stable flame hole 6 and each main fire hole 3 interlaced arrangement successively.
During burning, combustion gas and the gaseous mixture of air in mixing chamber 2 spray in each stable flame hole and main fire hole, burn, by Go up greatly the least 2 times in mixing chamber, therefore, it is possible to ensure the flow velocity of gaseous mixture, make stable flame hole flame to steady to the root of main fire hole flame Fixed burning, effectively prevent tempering phenomenon;In stable flame hole, the flame of ejection is incorporated in main fire hole flame simultaneously, improves heating Efficiency.
