Abstract

The invention is an energy-saving and environment-friendly flame cover for the open fire stove, belonging to an energy-saving and environment-friendly device matching the civil gas/oil open fire stove. The invention consists of a cover (1), an upper mouthpiece (2), an lower mouthpiece (3) and spider leg. At present, the original design of the civil gas/oil stove is open fire and the utilization ratio of heat energy is only about 50 per cent. The fuel is not burnt to the root, so the emission pollutes the environment. The purpose of the utility model is to install a metal cover (1) for the open fire of the civil gas/oil stove to isolate the flame from the air and form a pan bottom type high-temperature combustion chamber (8) between the pot body (7) and kitchen range mouthpiece (9), thus stopping the escape of heat energy. Because the high temperature of high-temperature combustion chamber (8 ) exceeds 1,300 Celsius system, the fuel can be burnt more fully and the emission is reduced effectively. If this utility model is used for the civil open fire gas/oil stove, the heat energy utilization ratio of the present gas stove can be raised from 50 per cent to more than 75 per cent.

Description

Naked fire cooking stove energy conservation environment protection flame cover

Technical field the utility model relates to a kind of domestic gas fuel oil naked fire cooking stove increases the tubbiness metal flame cover device of installing, especially a kind of energy-conservation bad device of protecting.

Background technology is present, the former design of domestic gas Oil-burning range is the naked light burning, do not pay attention to the energy-conserving and environment-protective factor, flame appearance during burning directly contacts with air, the temperature difference is greater than 1000 ℃ mutually, cause nearly 50% heat energy to be escaped, so the heat energy utilization rate of present domestic gas Oil-burning range has only about 50% with flowing fast of air.Because be the naked light burning, it is insufficient that comburant burns, and causes the emission contaminated environment.

Utility model content the purpose of this utility model is, flame when giving the burning of domestic gas Oil-burning range naked light is installed metal cap (1) completely cuts off the surface of flame and air, and forms the high temperature combustors (8) of pot bottom type shape at pot body (7) and kitchen range interface (9).Effectively stoped the escape of heat energy.Because the high temperature of high temperature combustors (8) surpasses 1000 ℃, and comburant is burnt more fully, has effectively reduced emission.Experiment showed, that the utility model can have only present domestic gas Oil-burning range the heat energy utilization rate about 50% to improve 50% again, reaches more than 75% the heat energy utilization rate.Last interface (2) can carry out activity according to the difformity the bottom of a pan and connect, miniature contact gap after the connection is as steam vent (6), be equipped with and the active stent foot (4) that is connected of any naked fire cooking stove kitchen range interface (9) at lower interface (3), the gap between the stent foot (4) is as air admission hole.

The utility model with there to be technology to compare, following good effect is arranged: because of the design defective, the heat energy utilization rate of domestic gas fuel oil naked fire cooking stove is too low, has only about 50%, this is worldwide, a historical difficult problem." household gas utensils " state compulsion standard code of the up-to-date appearance of China: gas kitchen ranges heat energy utilization rate is 〉=55%.In fact, 50% of gas kitchen ranges heat energy by slatterning in vain.The utility model can make present gas kitchen ranges heat energy utilization rate bring up to more than 75% by 50%, is higher than state compulsion standard thermal utilization rate and is 〉=55% more than 20 percentage points.

The utility model is simple in structure, and cost is low, and energy-saving effect is remarkable, has the energy-saving and environmental protection double effects, is the revolution to the gas kitchen ranges power-economizing method, and the utility model is promoted the use of and can be produced huge economic benefit and social benefit.

The utility model is easy to use, is easy to promote, and does not need existing stove and accessory, pot body are carried out any technological improvement, can realize active the connection with the utility model.

Description of drawings Fig. 1, structural representation of the present utility model

Fig. 2, the utility model and pot body, kitchen range interface activity are connected to form pan bottom shape high temperature combustors schematic diagram

The planar structure schematic diagram of the active connecting interface of Fig. 3, the utility model and kitchen range interface

The floor map of Fig. 4, the utility model and the active connecting interface of pot body

The specific embodiment: describe the utility model in detail below in conjunction with accompanying drawing; and provide an example: naked fire cooking stove energy conservation environment protection flame cover (1); be that one (2) suitable for reading are big; the tubbiness metal flame cover device that end opening (3) is little; (2) suitable for reading can realize active the connection with the pot body (7) of Any shape, specification; end opening (3) has 3-5 stent foot (4) to realize active the connection with the former pot body stent interface (9) of the cooking stove of any specification, the high temperature combustors (8) of formation pot bottom type shape.The utility model has the function that replaces pot body stent simultaneously.Air flows into from air admission hole (5), with comburant mixed combustion, forms the high temperature aspect of conducting heat to the bottom of a pan more than 1300 ℃ in the combustion chamber (8) of pot bottom type shape, and the micro-waste gas after the burning flows out from steam vent (6).

Claims

1, naked fire cooking stove energy conservation environment protection flame cover is gone up interface (2) lower interface (3) lower interface stent foot (4) by tubbiness cover body (1) and is formed, and it is characterized in that: tubbiness cover body (1) forms pot bottom type high temperature combustors (8) with the bottom of a pan (7) kitchen range interface (9).

2, according to the described naked fire cooking stove energy conservation environment protection flame cover of claim 1, it is characterized in that: going up interface (2) can carry out the active interface that connects according to the difformity the bottom of a pan.

3, according to the described naked fire cooking stove energy conservation environment protection flame cover of claim 1, it is characterized in that: be equipped with and the active stent foot (4) that is connected of any naked fire cooking stove kitchen range interface (9) at lower interface (3).
