Protrusion 112 is provided with multiple inside fire holes 1121 in inner bulge 112, and inside fire hole 1121 runs through inner bulge 112, in reality
In the application environment of border, inner bulge 112 supports cookware, and inside fire hole 1121 is set in inner bulge 112, is equivalent to inside
Raised 112 indents, and inside fire hole 1121 is connected to through inner bulge 112 with external, therefore inside fire hole 1121 will not be because
The problem of pot causes air supplement insufficient, the thermal efficiency is caused to reduce is sat for cookware.
It please referring to shown in Fig. 1, Fig. 3 and Fig. 4, outside ontology 120 is provided with the second main surface 121, in the present embodiment,
Second main surface 121 is the body surfaces that outside ontology 120 is used to support cookware in actual application environment, the second main surface
It is provided with multiple outside protrusions 122 on 121, interconnected the first outside fire hole 1221 and is provided in outside protrusion 122
Two outside fire holes 1222, the first outside fire hole 1221 is by close to 1222 end of the second outside fire hole to the outer surface of outside protrusion 122
Through the outside protrusion 122, the second outside fire hole 1222 is outside outside protrusion 122, the first outside fire hole 1221 and second
Side fire hole 1222 is the flute profile fire hole of depth gradual change, and the orifice area of the first outside fire hole 1221 is less than the second outside fire
The orifice area in hole 1222.
In the present embodiment, the first outside fire hole 1221 is set to the bottom of the second outside fire hole 1222, the second outside fire
Hole 1222 is equivalent to raised 122 indents in outside and the second outside fire hole 1222 through outside protrusion 122, in actual application environment
In, outside protrusion 122 supports cookware to sit pot, and the first outside fire hole 1221 is contacted with outside air with the second outside fire hole 1222
Well, air supplement is unaffected, therefore the thermal efficiency will not reduce.Meanwhile first outside fire hole 1221 compare second outside fire
1222 orifice area of hole is small, is not susceptible to from flame, and the first outside fire hole 1221 is equivalent to the steady flame slot of the second outside fire hole 1222,
In practical applications, it is equivalent to the first outside fire hole 1221 and lights the second outside fire hole 1222, the setting of the first outside fire hole 1221
In the bottom of the second outside fire hole 1222, so that the second outside fire hole 1222 does not occur from flame yet.
Inferior body 110 and outside ontology 120 are cyclic structure, and the outer rim of inferior body 110 and outside ontology 120
Inner edge connection.
Please continue to refer to described in Fig. 3, outside protrusion 122 is provided with sequentially connected the 1223, second protrusion of first crowning
Face 1224 and third protrusion face 1225, the first crowning 1223 and third protrusion face 1225 are prolonged by the inner edge of outside ontology 120
It extends to outer rim and is obliquely installed in 121 on the second main surface, and be obliquely installed towards the second crowning 1224, the second crowning
1224 and second main surface 121 be relatively arranged between the first crowning 1223 and the second crowning 1224.In the present embodiment
In, the first crowning 1223 is mutually drawn close with third protrusion face inclined direction, the first crowning 1223, the second crowning 1224 and
Third protrusion face 1225 is rectangular surfaces.
Second outside fire hole 1222 is set on third protrusion face 1225, and direction of slotting is perpendicular to third protrusion face
1225, and outside protrusion 122 is run through by the outer rim of outside ontology 120 to inner edge.In the present embodiment, the second crowning 1224
For the contact surface of outside protrusion 122 and cookware, the second outside fire hole 1222 is set on third protrusion face, avoids cookware to air
The interference of supplement, meanwhile, outside protrusion 122 is run through by outer rim to the inner edge of outside ontology 120, fire hole is easy to clean.
Second outside fire hole 1222 be rectangular channel, and its groove depth by outside ontology 120 outer edge to interior acies by
Cumulative big, the first outside fire hole 1221 is rectangular channel, length less than the second outside fire hole 1222 length, in the present embodiment
In, width is equal to the width of the second outside fire hole 1222, and the groove depth of the first outside fire hole 1221 is by close to the second outside
One end of one end of fire hole 1222 to the outer rim close to outside ontology 120 is gradually increased, in actual application environment, because first
Outside fire hole 1221 is closest to the fire hole of 100 outer rim of fire cover, and speed air flow is fast, the fluting of the first outside fire hole 1221
Depth close to one end of the second outside fire hole 1222 to one end of outer rim close to outside ontology 120 by being gradually increased, when burning
When primary air is filled by the first outside fire hole 1221 close to one end of 120 outer rim of outside ontology, groove depth is gradually reduced, air resistance
Power is gradually increased, and the flow velocity of primary air reduces, and avoids the generation from flame phenomenon.
The fluting direction of inside fire hole 1121 and the first main surface 111 are in angle and to the first main surface 111 is directed toward, equally
, inside fire hole 1121 is also rectangular channel.
Fire cover 100 provided by the utility model is combined by inner bulge 112 with inside fire hole 1121, outside protrusion
122 and first outside fire hole 1221 and the second outside fire hole 1222 combination, ensure that fire cover 100 provided by the utility model has
Have compared with high thermal efficiency, while the special setting mode of the first outside fire hole 1221 and the second outside fire hole 1222, avoids from flame
The generation of phenomenon, fire hole is to run through setting, easy to clean.
Second embodiment
The present embodiment provides a kind of gas cookers, and including the fire cover 100 that body and first embodiment provide, fire cover 100 is set
It is placed on body.In the present embodiment, body plays a part of to arrange fuel gas pipeline and fuel gas pipeline valve is arranged, while also acting as branch
Support the effect of fire cover 100.
Gas cooker provided by the utility model does not occur from flame phenomenon, and the thermal efficiency is higher, saves user cost.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
