Abstract

An infrared ray burner includes an upper combustion layer ceramic plate, a lower combustion layer metallic plate, a shell, a ferrule and a wire netting. An air inlet pipe is arranged on the shell, a hole capable of containing a combustion gas nozzle is arranged at outer end of the air inlet pipe, an air inlet is arranged on the air inlet pipe, the shell is of a circle shape, and a lower air inlet of the lower combustion layer metallic plate is arranged at center of the shell. The lower combustion layer metallic plate is mounted on the shell through fireproof, heat insulation and sealing material, and is isolated from the shell. The upper combustion layer ceramic plate is fixed on the shell through the ferrule, the upper combustion layer ceramic plate is parallel with the lower combustion layer metallic plate, a circuit of small holes on the ferrule are upper air inlets of the lower combustion layer metallic plate, and the wire netting is mounted in the shell below the lower combustion layer metallic plate. When used, combustion gas is injected into the air inlet pipe of the shell by the nozzle, is mixed with the entered air, comes out through holes of the lower combustion layer metallic plate, and is ignited by a igniter. Flame heats the upper combustion layer ceramic plate, uncombusted combustion gas comes out from the small holes of the upper combustion layer ceramic plate, is burned again when contact with air and generates stronger infrared ray. The infrared ray burner is suitable for baking oven and cooking stove.

Description

Infrared burner

Technical field:

The present invention relates to a kind of baking oven and cooking stove infrared burner.

Background technology:

Baking oven of Xiao Shouing and cooking stove all are made up of shell and ceramic honey comb plate with infrared burner in the market, and air inlet pipe is arranged on the shell, and there is the hole that gas nozzle is installed the outer end of air inlet pipe, and air inlet is arranged on the air inlet pipe.Following shortcoming is arranged when adopting the infrared burner of this structure to make baking oven:

1, burning is insufficient, and when gas valve opening was arrived maximum, the stainless steel bar that is placed on baking oven top 20 centimeters was immediately by sooting.

2, be easy to be put out,, be not suitable for open-air use as long as just give a puff and baking oven can be blown out with mouth by wind.

3, thermal inertia is big, needs for a long time to burning the red pottery porcelain plate from lighting stove fire again, also has this situation when regulating stove fire.

During 4, as the smoke-less oven, the thermal efficiency is very low.The infrared burner of smoke-less barbecue is tilted or vertically lays, the food of barbecue heats by the infrared radiation of baking oven entirely, and the flame of existing infrared burner burns on ceramic wafer, most of heat is used for the air on heating ceramic surface, and the ascension at once of these heated air and carbon dioxide is left away, can heat food.

When existing infrared burner was used on the cooking stove, combustion gas was burnt on the ceramic honeycomb plate, except the air of heating ceramic honey comb plate top, also heated the ceramic honeycomb plate, made it rubescent, had produced infrared radiation.Except air that heating is arranged with the heat transferred the bottom of a pan, also have infrared radiation to transmit heat and give the bottom of a pan, so the thermal efficiency increases, but still have the potential to be tapped.

Summary of the invention:

The present invention can overcome the defective of existing infrared burner.Infrared burner of the present invention is made up of shell, last burning zone ceramic wafer, following burning zone metallic plate, ferrule, wire netting.Material fire-resistant with having, adiabatic, sealed characteristic will descend the burning zone metallic plate to isolate, and be fixed on the shell.The circular hole of many projectioies or the slit of projection are arranged on the following burning zone metallic plate.With ferrule last burning zone ceramic wafer is fixed on the shell, last burning zone ceramic wafer is parallel with following burning zone metallic plate.One circle aperture is arranged in the ferrule, is the last air inlet on the following burning zone metallic plate.Shell is " returning " font, and central authorities are following air inlets of following burning zone metallic plate, and air inlet pipe is arranged on the shell, and there is the hole that gas nozzle is installed the outer end of air inlet pipe, and air inlet is arranged on the air inlet pipe.Have in the shell and be parallel to the wire netting of burning zone metallic plate down.Last burning zone ceramic wafer can be foam-like ceramic wafer or ceramic honeycomb plate, and the ceramic wafer surface can be concavo-convex alternate irregular structure, and spraying plating one deck tungsten.Adopt the infrared burner of this structure, when being used on the baking oven, combustion gas sprays from nozzle, enter after the housings with enter shell in air mix, from the aperture of following burning zone metallic plate, come out, lighted by igniter, air helps fuel gas buring above the openning of the aperture of ferrule and shell central authorities enters down the burning zone metallic plate.Flame on the following burning zone metallic plate burns the red stronger infrared radiation of sending with top last burning zone ceramic wafer heating, contacts burning for the second time with air after unburnt combustion gas is come out from the hole of last burning zone ceramic wafer, so ratio of combustion is more abundant.During open-air the use, the flame under strong wind can not blown out yet on the burning zone metallic plate.Because the last burning zone ceramic wafer that uses is thinner, lighter weight is so thermal inertia is less.Because the residue combustion gas is burnt on last burning zone ceramic wafer, the hot gas lta that produces, so upwards ascension, when leaving, produce negative pressure on last burning zone ceramic wafer surface, flame under this negative pressure attracts by the hole on the last burning zone ceramic wafer on the burning zone metallic plate, no matter infrared burner tilts or vertical the use, flame on the following burning zone metallic plate all can point to burning zone ceramic wafer generation infrared ray in burning zone ceramic wafer, the heating, has only the remaining combustion gas of small part to add hot-air in the surface combustion of last burning zone ceramic wafer.So the infrared ray that produces is stronger, heated air is less.For the smoke-less oven, the thermal efficiency improves a lot.

When infrared burner of the present invention is used on the cooking stove,, have only the combustion gas of fraction residue on last burning zone ceramic wafer, to burn because most of combustion gas is being burnt on the burning zone metallic plate down, the flame on the above burning zone ceramic wafer lower.We can be the bottom of a pan near last burning zone ceramic wafer, and does not influence fuel gas buring.If last burning zone ceramic wafer uses rough ceramic wafer, we can go up the burning zone ceramic wafer to the bottom of a pan contact, the residue combustion gas is in sunk local burning, because the bottom of a pan is with last burning zone ceramic wafer contact area is less can not take away most of heat of last burning zone ceramic wafer, and the combustion gas of influence residue is burnt in the sunk place of last burning zone ceramic wafer.We know that heat transmission has three kinds of modes, and directly transmission efficiency is the highest, and when indirect transfer and radiation delivery, thermal source and heated body are high more the closer to heat transference efficiency.So when infrared burner of the present invention was used on the cooking stove, thermal efficiency order improved widely.
