Description

Technical Field

[0001] The utility model relates to a burner for a gas stove, in particular to a burner combined with stainless steel and aluminum alloy materials. Background Art

[0002] At present, most of the gas stove burners used in the domestic stove market are composed of aluminum die-casting, aluminum casting, copper forging combustion body and copper fire cover. Under the current high copper price, there are disadvantages of high material cost and heavy emission pollution. In response to this, a variety of stainless steel burners have been launched on the market to reduce production costs. However, since stainless steel burners are made of thin plate materials and the fire holes of the burners are designed in strip-shaped, small-hole and other structural forms, there are also defects such as flame continuity and floating flames. Utility Model Content

[0003] The utility model aims to provide a combined burner with reasonable structure, scientific materials, low cost, energy saving and environmental protection, high temperature resistance, high combustion thermal efficiency and clear combustion flame.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions. The combined burner includes a large fire cover, a large fire guide plate, a small fire cover, a small fire guide plate and a combustion body. The large fire cover, the large fire guide plate, the small fire cover and the small fire guide plate are all made of stainless steel plates, and the combustion body is made of aluminum alloy. The large fire cover is arranged on the upper part of the combustion body, and a segmented groove is arranged on the large fire cover. The outer ring cone surface is provided with a whole row of large fire holes, and the segmented radial cone surface and the inner inclined surface are provided with fire transfer holes. The large fire guide plate is arranged below the large fire cover at an interval of 2-6 mm, and its appearance is similar to the large fire guide plate. Correspondingly, the lower plane of the outer circle of the large fire guide plate is connected to the upper plane of the outer circle of the combustion body. The vertical surface of the inner circle is provided with two concave notches to cooperate with the positioning columns of the combustion body for positioning. The small fire cover is arranged above the core of the combustion body. The small fire cover is a conical shell. A whole row of small fire holes is arranged on its small fire outer conical surface. The small fire guide plate is arranged below the small fire cover at an interval of 2-6 mm. Its outer shape is a conical shell. The inner side surface of the small fire guide plate is fitted with the end face of the anti-dry burning tube, and the inner side surface of the small fire cover is fitted and sealed with the inner side surface of the anti-dry burning tube.

[0005] The combined burner has an outer ring of a high fire cover and an outer ring of a combustion body, an inner ring of a high fire cover and an inner ring of a combustion body, and an outer ring of a low fire cover and an outer ring of a central core of the combustion body.

[0006] Since the utility model adopts the above technical scheme, it has the following beneficial effects: (a) due to the innovative design of the annular segmented structure of the large fire cover, the burner has a heavy feeling, and the burning flame is clear and the flame is blue; (b) due to the large fire guide plate arranged at a distance of 2-6 mm below the large fire cover, its shape corresponds to the large fire guide plate, and a gap of 2-6 mm is formed between the two, so that the gas pressure distribution of the large fire cover is uniform and the flame combustion state is clear; (c) due to the small fire guide plate arranged at a distance of 2-6 mm below the small fire cover, a gap of 2-6 mm is formed between the two, so that the gas pressure distribution of the small fire cover is uniform and the flame combustion state is clear; (d) due to the use of an integrated riveted structure of the large fire cover and the small fire cover, it has the advantages of simple process and stable and firm structure; (e) due to the raw materials of the burner fire cover are all made of stainless steel plates, which have excellent properties of high temperature resistance and corrosion resistance, and at the same time, it has the characteristics of high production efficiency, mass production, no pollution, low energy consumption and environmental protection in production process.
