Abstract

The utility model discloses a novel gas cooker burner fire cap, whose cap body is ring shaped structure, the cap body of the fire cap respectively has fire holes with circular and bar, and a gap, adopting the special pottery moulding technics for moulding, and adopting the special pottery preparation technique, made of incompletely sintered pottery material, whose surface has a heat resisting paint and glaze, in contrast with the fire cap made of routine copper product or cast iron material, the utility model has the distinct advantages of low product cost, enhancing heat resisting, anti corrosion performance, non deforming and oxygen proof performance of the product, long thermal stability and long service life of the product.

Description

A kind of burner fire lid of gas kitchen ranges

Technical field

The utility model relates to a kind of improvement of domestic gas kitchen range burner, especially the improvement of burner for gas stove fire lid.

Background technology

Gas kitchen ranges is used by the family of China widely, and present gas kitchen range fire cap is owing to the reason of manufacturing process and combustibility requirement, now all be that metal material is made, great majority adopt cast iron materials or copper to become, these fire lids have processing technology less demanding, be easy to the advantage transporting and deposit, but it has the defective of following aspect.

(1) these materials are owing to be metal material, and thermal conductivity factor is big, and its heat conduction is fast, and when the primary air amount is big, or flame tempering phenomenon occurs when burning easily near fire hole, and the anti-tempered performance of product is poor.

(2) heat resistance is poor, and when fire lid higher temperatures, occur distortion easily, thereby cause product normally to use, or life of product difference or tempering phenomenon occurs.

When (3) easily oxidized and corrosion, especially higher relatively or Acidity of Aikalinity is stronger kitchen condition in temperature, product be prone to because oxidized, corrode and cause service life poor.

(4) product cost is higher, especially uses the more apparent product of situation of copper product significantly very high, and has consumed too many copper product resource.

(5) if adopt the ceramic material manufacturing, because the ceramic material water absorption rate is smaller or equal to 0.5%, its thermal shock resistance is poor, anti-rapid heat cycle poor performance, and life of product is poor.

Summary of the invention

The purpose of this utility model is, by employing new technology and new production technology, adopt the nonmetallic materials of novel low thermal coefficient of expansion and anticorrosive oxidation, good thermal shock, adopt special forming technique and firing process, providing a kind of product cost low and product heat resistance, decay resistance, anti-deformation and anti-oxidation performance are good, the gas stove burner fire lid of product heat endurance, long service life.

The utility model is realized by the following technical solutions: a kind of burner fire lid of gas kitchen ranges, fiery cap body (1), burning fire hole (2) by annular are formed, fire cap body (1) is that ceramic material between 2% and 35% is made by water absorption rate, burning fire hole (2) can be circular fire hole, also can be bar shaped fire hole, trapezoidal fire hole, or the slit-shaped fire hole; Burning fire hole (2) can be that row's fire hole or two row's fire holes distribute, and also can be that many row's fire holes or irregular fire hole are arranged; There is the resistant to elevated temperatures organic coating of one deck on the surface of fire cap body (1), and one deck inorganic color is perhaps arranged, and one deck ceramic glaze is perhaps arranged.The ceramic material of fire cap body (1) is made up of ceramic raw material such as cordierite, mullite, aluminium titanates, lithium raw material or their mixture, its product forming technique is different from the mechanical processing technology of copper or cast iron materials fire lid fully, and its adopts is methods such as half-dried molded, injection forming, injection moulding or hot injection moulding.Like this, owing to adopted manufacturing process such as new moulding and firing process, the material coefficient of thermal expansion coefficient is low, and burner fire lid heat resistance of the present utility model is good, good thermal shock, anti-tempering ability is strong, and resistance to corrosion is good, product cost is low, and the situation of temperature distortion can not appear in long service life.

Advantage of the present utility model is, product cost is low, heat resistance good, good thermal shock, good, the anti-tempering ability of heat endurance is strong, resistance to corrosion is good, long service life, no temperature distortion.

The specific embodiment

Embodiment 1 (seeing Fig. 1, Fig. 2):

A kind of burner fire lid of gas kitchen ranges is made up of the fiery cap body (1) of annular, burning fire hole (2), and fiery cap body (1) is that ceramic material between 2% and 35% is made by water absorption rate, and the fire hole (2) that burns is trapezoidal fire hole; The ceramic material of fire cap body (1) is that primary raw material is formed with the cordierite, and its product forming technique is different from the mechanical processing technology of copper or the fiery lid of cast iron materials fully, adopts the moulding of hot die-casting molding method; The upper surface of fire cap body (1) has the resistant to elevated temperatures organic coating of one deck.Like this, owing to adopted manufacturing process such as new shaping and firing process, the material coefficient of thermal expansion coefficient is low, and this burner fire lid heat resistance is good, good thermal shock, anti-tempering ability is strong, and resistance to corrosion is good, product cost is low, and the situation of temperature distortion can not appear in long service life.

Embodiment 2 (seeing Fig. 3, Fig. 4):

With embodiment 1, the fire hole (2) that just burns is circular fire hole.

Embodiment 3 (seeing Fig. 5, Fig. 6):

A kind of burner fire lid of gas kitchen ranges, external ring fire cover lid (1), outer shroud burning fire hole (2), the fiery cap body of interior evil idea (3), interior ring fire hole (4) by annular are formed, external ring fire cover lid (1) and interior ring fire cap body (3) are that ceramic material between 2% and 35% is made by water absorption rate, and burning fire hole (2) is trapezoidal fire hole.The ceramic material of fire cap body (1) and interior ring fire cap body (3) is formed by primary raw material with the cordierite, its product forming technique is different from the mechanical processing technology of copper or cast iron materials fire lid fully, adopt the moulding of hot die-casting molding method, the upper surface of fiery cap body (1) has one deck inorganic color.Like this, owing to adopted manufacturing process such as new shaping and firing process, the material coefficient of thermal expansion coefficient is low, and this burner fire lid heat resistance is good, good thermal shock, anti-tempering ability is strong, and resistance to corrosion is good, product cost is low, and the situation of temperature distortion can not appear in long service life.
