Technical Field

The invention relates to an integrated cooker, in particular to a gas cooker in the integrated cooker.

Background

At present, most of external fire covers on integrated cookers are external fire covers on traditional gas cookers, and the outermost ends of the external fire covers of most cookers are provided with a circle of external fire. The outer ring fire holes of the outer fire cover can block air from supplementing the inner ring fire holes during combustion, so that the inner ring fire is not combusted fully; secondly, the distance of the smoke stove on the integrated stove is shorter than that of the traditional smoke stove, the wind generated by the integrated stove at the working process of the oil absorption device can enable the outer fire ring of the outer fire cover to be virtual long, and the flame is burnt to the outside of the pot bottom, so that the flame cannot be sufficiently utilized, and the heat loss is caused.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: an external fire cover structure is provided which overcomes the above-mentioned deficiencies.

The solution of the invention for solving the technical problem is as follows: an outer fire cover comprises a cover body which is annularly arranged, wherein the cover body comprises a bottom surface, an upper end surface and a central arc surface, the upper end surface is positioned above the central arc surface, and the bottom edge of the upper end surface is superposed with the upper edge of the central arc surface; the included angle between the upper end face and the bottom face is alpha, wherein 20 degrees < alpha <40 degrees; the upper end face is provided with a plurality of bosses, a first layer of fire outlets are arranged in the bosses, a second layer of fire outlets are arranged on the upper end face, and a third layer of fire outlets is arranged on the central cambered surface.

The invention has the beneficial effects that: the structure of the outer fire cover is high outside and low inside, and the upper end surface of the outer fire cover is obliquely arranged in an inward concave shape with the horizontal plane; the upper end face of the cover body is provided with a boss, the boss is provided with a first layer of fire outlet, the upper end face of the cover body is provided with a second layer of fire outlet, and the central arc surface is provided with a third layer of fire outlet; meanwhile, the flame on the outer fire cover is layered, so that flame connection phenomenon during combustion can be avoided, air can smoothly enter the inner part of the outer fire cover due to the fact that the air is not blocked by the outer fire in the combustion process, and air can be supplemented more fully.

As a further improvement of the technical scheme, the cross section of the first layer of fire outlets is prolate, and the included angle between the opening direction of the first layer of fire outlets and the upper end surface is beta₁Wherein 30 DEG C<β₁<80 degrees. After adopting above-mentioned structure, can reduce the influence of wind to flame, prevent that wind from lengthening flame, maintain combustion stability.

As a further improvement of the technical scheme, the included angle between the opening direction of the fire outlet on the second layer and the upper end surface is beta₂Wherein 30 DEG C<β₂<80°。

As a further improvement of the technical scheme, the number of the first layer fire outlets is the same as that of the second layer fire outlets, and one second layer fire outlet is arranged between every two adjacent first layer fire outlets.

As a further improvement of the technical scheme, all the bosses are uniformly distributed on the upper end face, and all the second-layer fire outlets are uniformly distributed on the upper end face.

As a further improvement of the technical scheme, the cross section of the third layer of the fire outlets is circular, the number of the third layer of the fire outlets is multiple, and the multiple third layer of the fire outlets are uniformly distributed on the central cambered surface.

As a further improvement of the technical scheme, the central cambered surface comprises an air supply through groove, and the air supply through groove is positioned below the third layer fire outlet. Through above-mentioned structure, can improve the air supply of outer fire lid, the burning is more abundant, improves combustion efficiency.

The invention also provides a burner for a gas stove, which comprises a burner and the outer fire cover, wherein the burner is provided with an outer gas cavity, and the outer fire cover is communicated with the outer gas cavity. The outer fire cover of the embodiment has at least the beneficial effects of the outer fire cover.

The invention also provides an integrated cooker applying the burner.
