Abstract

The utility model relates to an improvement of a stove burner, which is composed of a stove head seat and a stove head hood, wherein, the stove head hood is a tabular body made of mixed refractory volcanic ash-stone powder and nickel-chromium alloy, is provided with dense meshy gas holes and can be matched and assembled with the stove head seat; the inner part of the gas holes are provided with a plurality of volute convex ribs with a proper slope rate; the volute convex ribs can guide gas to cause volute air current outside the holes, so that each gas hole becomes an independent outer burning chamber to prompt oxygen and gas to be thoroughly mixed and reduce the generation of carbon monoxide gas. Thus, the utility model can meet requirements of environmental protection and security, obtain larger heat power efficiency, save energy and achieve the effects of practicality, safety, convenience and long service life.

Description

Furnace head burner

The utility model relates to a kind of improvement structure of furnace head burner, by the close and netted fuel gas hole structure of porous of burner cover, be provided with the volute fin in the hole and form eddy airstream with guiding gas, making oxygen and gas can fill part mixes, the generation of CO gas when reducing burning, compliance with environmental protection requirements, and can obtain bigger heat power efficiency reduces cooking time and has concurrently and saves the energy and enforcement, safety, convenience.

The gas burner radiation ceramic plate structure (shown in the cut-away view of Fig. 1) of common infrared heating heating furnace, be on burner 4 bodies, to be set as radiation pottery plate 5, and fixed by some fasteners 6, by the top 411,421 of burner 4 with radiation pottery plate 5 installing frame inner edges and

gas chamber clapboard

41,42, be designed to have ring-like prominent height, with the structure of rotary-cut air-flow promotion with the oxygen mix ratio.

Yet, the structure of this kind gas burner radiation ceramic plate, the flame 7 of methane gas generation is fuel gas hole 51 surface combustions at radiation pottery plate 5 in use, cause the disk body central authorities higher point place can't heat build-up, heat energy efficiency when hotting plate article is reduced, and the diffusion of the radiant heat of pan periphery, high heat around producing, cause heat radiation to scatter, waste energy and use inconvenience, and press close to burning when long of radiation ceramic plate surface high temperature, very easily reduce shortcomings such as service life because of flame.

In view of the foregoing, the inventor is at those unreasonable structure places, improves.

The utility model aims to provide a kind of improvement of furnace head burner structure, the burner cover of this burner has intensive netted fuel gas hole, establish the volute fin of the suitable slope of tool in the hole, can make oxygen and gas fill part mixes, reduce the generation of CO gas, and flame concentrates and not press close to surface combustion again, can obtain big heat power efficiency, reduces cooking time and also has the purpose of saving the energy, practicality, safe ready and increasing service life concurrently.

As for detailed construction of the present utility model, application principle, effect and effect, then be further described as follows with reference to following adjoint:

Fig. 1 is the cut-away view of common gas burner radiation ceramic plate structure.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is the three-dimensional generalized section of burner cover fuel gas hole of the present utility model.

Fig. 4 is a structure cut-away view of the present utility model.

Please referring to Fig. 2, shown in Figure 3, by finding out in graphic, the utility model can be installed on traditional furnace head base 1, this furnace head base 1 is by a plurality of gas adapting pipes 11,13 formations of ring in one outer shroud 12 and, wherein, be provided with an outer air chamber 121 in the outer shroud 12, should a plurality of pores 122 have been provided in outer air chamber 121 surfaces, interior ring 13 inner tools are provided with air chamber 131 in, provided a plurality of pores 132 on interior air chamber 131 surfaces, made gas derive burning through the pore 122,132 of inside and outside air chamber 121,131 by adapting pipe 11; And burner cover 2, mainly be by resistant to elevated temperatures volcanic ash stone flour, reach the housing body structure that nichrome is made, cover body provides intensive netted fuel gas hole 21, be provided with the volute fin 122 of the suitable slope in a plurality of roads in this fuel gas hole 21, and learn that according to experiment the best slope of this volute fin 211 is by vertical angle 15 to 25 degree that tilt.

Please see shown in Fig. 4 again, after both assemble and cooperate when burner cover 2 and furnace head base 1, volute fin 211 in the fuel gas hole 21 of burner cover 2, bootable gas air-flow of deriving by furnace head base 1, outer surface at fuel gas hole 21 produces eddy airstream, making oxygen and gas more fill part mixes, effectively reduce the generation of CO gas when reaching burning, increased security, because of the volute fin 211 in the fuel gas hole 21, can make flare do burning fully in a suitable elevation-over, this flare is more near the pan bottom, then the heat energy efficiency loss is few more, can shorten and hot plate the time fuel saving, be convenient to the demand of need again, and the heat build-up of burner cover 2 reaction also reduces than the big flame person of hotting plate, increase service life relatively, is its another characteristics.

In sum, the utility model furnace head burner, really has the generation that reduces carbon monoxide, meet environmental protection, safety requirements, and obtain big heat power efficiency, reduce cooking time and have the saving energy concurrently, the cover body surface is difficult for high heat and burns out, increase the effect in service life, changed the deficiency in the prior art structure, reached inventor's goal of the invention.
