Description

Inner ring fire cover and kitchen range burner with same

Technical Field

The utility model belongs to the technical field of household kitchen ware, and particularly relates to an inner ring fire cover and a kitchen range burner with the same.

Background

The inner ring fire cover of the existing kitchen range burner generally comprises a fire cover body with an open upper part and a cover body arranged on the opening part of the fire cover body in a covering way, wherein the fire cover body is provided with a fire outlet. In the cooking process, overflowed liquid overflowed from the cooker can drop onto the cover body and flow downwards to the fire cover body along the cover body, so that the fire outlet hole on the fire cover body is plugged, and further the problems of accidental flameout, poor ignition and the like of the burner are caused.

In order to overcome the defects of the inner ring fire cover of the existing burner, the inner ring fire cover disclosed in the utility model patent application No. CN201710447014.1 (application publication No. CN 108006641A) of the utility model is provided with a fire cover body and a cover body, wherein the periphery of the cover body protrudes outwards from the fire cover body along the horizontal direction, at least part of the bottom of the periphery extends downwards to form a waterproof eave, and when the overflow flows to the periphery of the cover body, the overflow can flow and drop along the waterproof eave, so that the overflow is prevented from flowing into a fire outlet hole, and the flame is prevented from being extinguished. However, the structure of the cover body in the application can lead the overflow liquid to flow down randomly along the periphery of the cover body, and the flowing overflow liquid is easy to be influenced by external factors to flow into the fire outlet hole, so that the fire outlet hole is blocked.

In order to collect the overflowed liquid and make the overflowed liquid flow down along one side of the inner ring fire cover, the utility model patent No. 201922263295.2, an inner ring fire cover and a kitchen range burner using the inner ring fire cover (grant bulletin No. CN 211822385U) discloses a fire cover structure, which comprises a fire cover body and a cover body covered on the fire cover body, wherein a fire outlet hole is formed in the side peripheral wall of the fire cover body along the circumferential direction; the top of the cover body is downwards sunken to form a liquid containing groove for collecting the overflowed liquid, an opening communicated with the liquid containing groove and used for the overflowed liquid to flow out is formed on at least one side of the periphery of the cover body, and a diversion trench used for the overflowed liquid to flow down along the opening is formed on the side wall of the fire cover body. However, as part of the fire outlet holes are positioned in the diversion trench, the problem that the fire outlet holes in the diversion trench are blocked by the overflow liquid still exists.

Disclosure of Invention

The first technical problem to be solved by the utility model is to provide an inner ring fire cover aiming at the current state of the art so as to reduce the risk of blocking a fire outlet hole in a diversion trench.

The second technical problem to be solved by the utility model is to provide a kitchen range burner with the inner ring fire cover.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: an inner ring fire cover, comprising:

the fire cover comprises a fire cover body, wherein a diversion trench for overflows to flow down is formed in the peripheral wall of the fire cover body, the diversion trench is provided with a trench bottom wall extending up and down and trench side walls positioned at two sides of the trench bottom wall, and the trench bottom wall is provided with a fire outlet penetrating through the wall thickness;

the method is characterized in that:

the hole edge of the fire outlet hole extends outwards to form a convex part which is raised relative to the bottom wall of the diversion trench, and a gap for overflow liquid to flow down is formed between the convex part and at least one of the two trench side walls at intervals.

Therefore, the arrangement of the convex part does not influence the fire outlet of the first fire outlet hole, and meanwhile, overflow liquid can be prevented from entering the fire outlet hole, so that the risk of blocking the fire outlet hole in the diversion trench is reduced; and the overflow liquid in the diversion trench can flow down through the gap.

Preferably, the protrusion is located at a central position between the two groove side walls while being spaced apart from the two groove side walls. Thus, the overflow liquid in the diversion trench can flow down from the gaps at the two sides of the convex part.

In order to avoid that the overflow adheres to the protrusion, it is preferable that the lower surface of the protrusion is inclined downward from both sides to the center, thereby forming a downward pointed edge at the center. Thus, the overflow can be concentrated to the sharp edge along the lower surface of the convex part and fall from the sharp edge.

Further, the convex part is positioned at the upper part of the diversion trench.

Further, the distance between the two groove side walls at the upper part of the diversion trench is larger than the distance between the two groove side walls at the lower part of the diversion trench. Therefore, the fire holes can be formed in the two sides of the peripheral wall of the fire cover body, which are positioned at the lower part of the diversion trench, so that the overall structure is compact.

In the above schemes, in order to collect the spilled liquid better, preferably, the fire cover further comprises a cover body covering the fire cover body, wherein the top of the cover body is provided with a downward concave liquid receiving groove for collecting the spilled liquid, and a notch communicated with the liquid receiving groove is formed in the periphery of the cover body at a position corresponding to the diversion trench. Thus, the overflowed liquid can be collected in the liquid receiving groove and flows down from the diversion trench through the notch.

The liquid bearing groove can be realized by arranging a groove on the top surface of the cover body.

Preferably, the top surface of the cover body is convexly provided with a circumferentially extending baffle ring, and the baffle ring and the top surface of the corresponding cover body jointly define the liquid bearing groove.

Further, the baffle ring is positioned on the inner periphery of the cover body and is integrally C-shaped, and the C-shaped opening corresponds to the notch.

Further, the top surface of the cover body is inclined downwards, and the lowest point is located at the notch. Therefore, the overflow liquid on the top surface of the cover body can flow downwards and collect at the notch.

The utility model solves the second technical problem by adopting the technical proposal that: a kitchen range burner characterized by having an inner annular fire cover as described above.

Compared with the prior art, the utility model has the advantages that: the hole edge of the fire outlet hole is outwards extended to form a convex part protruding relative to the bottom wall of the diversion trench, and a gap for overflow liquid to flow down is formed between the convex part and at least one of the two trench side walls, so that the arrangement of the convex part does not influence the fire outlet of the fire outlet hole, and meanwhile, the overflow liquid in the diversion trench can be prevented from entering the fire outlet hole, thereby reducing the risk of blockage of the fire outlet hole in the diversion trench; and the overflow liquid in the diversion trench can flow down through the gap.
