Abstract

The utility model discloses a burning gas cooking appliance, which is composed of a coating and an inner bag that is sleeved on the inner sleeve of the coating; wherein, between the coating and the inner bag is provided with an enclosed interlayer hollow cavity, and the center of the inner bag is fixed with a hollow gas column; and the upper end of the gas column is provided with an air outlet hole, while the lower end of which is provided with an air inlet hole; and the outside of the coating has a wind inlet, while a fuel pipe is fixed on the wall of the inner bag through the wall of the coating; wherein, the wall of the inner bag is covered with an air inlet hole inclining to the horizontal direction, and the upper ends formed with the inner bag and the coating are provided with a fire-proof ring; and a primary and a secondary combustion chamber which are used for twice combustion, and the inclining hole on the inner bag can make the air and fuel materials in the primary combustion chamber form a convoluting inflammable mixed gas. Thus, compared with the current technologies, the utility model has higher degree of mixing with the air, and more complete burning and obvious energy saving effect, which can save 50 percents or more fuel oil with only 1.5 to 1.8 kg of diesel oil consumption per hour.

Description

A kind of burning kitchen range

Technical field

The utility model belongs to the burning kitchen range, is specifically related to a kind of burning kitchen range that use liquid or gaseous fuel.

Background technology

At present, generally use a kind of kitchen range of burning diesel oil at the restaurant, there is following problem in these kitchen range: the one, and energy consumption is higher, on average oil consumption 3.5-4.8 kilogram per hour; The 2nd, it is insufficient to burn, and the phenomenon of flame seedling is arranged; The 3rd, inner bag produces carbon distribution, stops up fire hole easily.This kitchen range can only burn diesel oil.

The utility model content

It is a kind of energy-conservation that the purpose of this utility model is to provide, sufficient combustion, the nonclogging burning kitchen range of fire hole.

The purpose of this utility model realizes in the following manner: the burning kitchen range have an overcoat, be set with an inner bag in the overcoat, form the interlayer cavity of a sealing between overcoat and the inner bag, the central authorities of inner bag are fixed with the gas column of a hollow, there is venthole the upper end of gas column, there is air admission hole the lower end, air inlet is arranged at the bottom of overcoat, cartridge passes overcoat wall and is fixed on the wall of inner container, be distributed with the air inlet inclined hole that tilts in the horizontal direction on the wall of inner container, the upper end that inner bag and overcoat are formed is provided with fire-resistant circle.

Operation principle of the present utility model: fuel (diesel oil, liquefied gas, aqua fuel etc.) enters in the inner bag from cartridge after pressurizeing, air enters the interlayer cavity that forms between overcoat and the inner bag from the air inlet of jacket bottom simultaneously, most of air forms high-speed rotational through oblique the entering in the inner bag of the air inlet inclined hole of wall of inner container periphery around gas column, make fuel atomization, and fully mix the formation burning mixture, carry out the burning first time in the primary zone that interior gallbladder intracavity forms; Another fraction air enters in the gas column from the lower end air admission hole of gas column, and again from the ejection of the venthole of upper end, the secondary combustion chamber that forms at fire-resistant circle inner chamber and carries out burning the second time after fuel also imperfect combustion in first time combustion process mixes once more.

In order to make the firepower after burning for the second time more concentrated, the inwall cavity of fire-resistant circle is the back taper of the contraction that makes progress.

For convenience kitchen range are installed on the kitchen range top, outer casing outer wall top is the sloping platform of an inverted cone shape.

Because the utility model is to utilize air to enter primary zone and secondary combustion chamber respectively from the interlayer cavity and the gas column of kitchen range, can carry out twice combustion, and the inclined hole on the inner bag can make air and the fuel so mist at the indoor formation eddy flow of primary combustion shape.Therefore, compare with existing diesel oil range, these kitchen range fuel and Air mixing degree are higher, and it is more abundant to burn, and energy-saving effect is remarkable, but fuel-economizing more than 50%, and per hour on average consuming diesel oil is the 1.5-1.8 kilogram.It is violent also to have firepower, and even at top speed, wall of inner container is carbon distribution not, and fire hole does not stop up, and can use advantages such as diesel oil, liquefied gas, aqua fuel pluralities of fuel.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The A-A view of Fig. 2 Fig. 1.

The specific embodiment

See Fig. 1, Fig. 2, the burning kitchen range have an overcoat 1, be set with an inner bag 4 in the overcoat 1, match with the convex edge 6 of inner bag 4 upper ends in the upper end of overcoat 1, make the interlayer cavity 13 that forms a sealing between overcoat 1 and the inner bag 4, the central authorities of inner bag 4 are fixed with the gas column 8 of a hollow with screw thread, there is the venthole 10 of horizontal direction the upper end of gas column 8, there is air admission hole 14 lower end, air inlet 15 is arranged at the bottom of overcoat 1, cartridge 2 passes overcoat 1 wall and is fixed on inner bag 4 walls with screw thread, be distributed with the air inlet inclined hole 3 that tilts in the horizontal direction on inner bag 4 walls, the upper end that inner bag 4 and overcoat 1 are formed is provided with fire-resistant circle 7, the back taper of inwall 11 for upwards shrinking of fire-resistant circle, and overcoat 1 outer wall top is the sloping platform 5 of an inverted cone shape.

Fuel oil enters in the inner bag 4 from oil pipe 2 by dotted arrow, and air enters in the inner bag 4 respectively and fire-resistant circle 7 inner chambers along solid arrow.Fuel oil in primary zone 12 that inner bag 4 inner chambers form by the high-speed rotational air atomizing, and mixing forms so mist, carry out the burning first time, secondary combustion chamber 9 in fire-resistant circle 7 inner chambers formation, air continues to mix with the most fuel oil of unburned when the primary combustion, carry out second-time burning, can reach clean-burning purpose.

Claims (3)

1, a kind of burning kitchen range, one overcoat is arranged, it is characterized in that being set with in the overcoat inner bag, form the interlayer cavity of a sealing between overcoat and the inner bag, the central authorities of inner bag are fixed with the gas column of a hollow, there is venthole the upper end of gas column, there is air admission hole the lower end, and air inlet is arranged at the bottom of overcoat, and cartridge passes overcoat wall and is fixed on the wall of inner container, be distributed with the air inlet inclined hole that tilts in the horizontal direction on the wall of inner container, the upper end that inner bag and overcoat are formed is provided with fire-resistant circle.

2, burning kitchen range according to claim 1 is characterized in that the back taper of the inwall cavity of fire-resistant circle for the contraction that makes progress.

3, burning kitchen range according to claim 1 and 2 is characterized in that outer casing outer wall top is the sloping platform of an inverted cone shape.
