Abstract
The utility model discloses a novel firewood-burning air returning furnace core that is comprised of a combust supporting cover; the wall and the bottom of the combust supporting cover are provided with a plurality of air intake holes. The utility model is characterized in that: a flame controlling cover formed by the extension of the opening of the combust supporting cover is also comprised; the flame controlling cover is comprised of a circular table-shape cover body; and combust supporting cover and the flame controlling cover form an integer structure. One improvement is that one side on the opening of the circular table-shaped cover body is provided with a flame stopping flange that is higher that the circumference. By adopting the structure, the furnace core has an easier and more reasonable structure, which easing manufacturing and installation and decrease about 40 percent manufacturing cost of the furnace core; besides, more than 70 percent firewood is saved compared with traditional firewood-burning furnaces; the flame force is concentrated with strong power, thus the speed of water heating and cooking is fast; in addition, the available combusts are much, since dry firewood, wet firewood, straws, husks, and sawdust can all be applied.
Description
Affiliated technical field
The utility model relates to a kind of Domestic stove, especially a kind of combustion chamber of making the air return stove of fuel with bavin.
Background technology
Air return stove of the prior art, its air return type combustion system makes the hot air circulate convection current in the flue, and energy-saving effect is remarkable, but it only can make fuel with coal, and can not satisfy has bavin not have the hope that coal area people burn air return stove.Inventor's original application number be the burning bavin air return stove patent of 02223070.x and 200420060330.1, solved the problem of burning bavin, but there is following shortcoming in it: 1, firewood combustion is insufficient, and smog is big; 2, its return air interlayer is too thick, has influenced heat and has crossed the furnace wall bitterly to external radiation, is not easy to heating; 3, firepower is small and scattered, is not easy to heat up water, cook; 4, the wood stove core is easily burnt out, the use cost height.
The utility model content
Problem to be solved in the utility model is to provide a kind of novel combustion bavin air return stove combustion chamber, and its combustion chamber is simple in structure, is convenient to make and install, and production cost is low, thermal efficiency height.The utility model adopts following technical scheme: comprise fuel holder cover, described fuel holder cover comprises the cover mouth and the cover end, its cover mouth is big, the cover end is less, the cover wall of described fuel holder cover and the cover end, are provided with some air inlet pores, also comprise the fire casing that extends upward from the cover mouth of described fuel holder cover, described fire casing comprises the truncated cone-shaped body, and described fuel holder cover and described fire casing are integral structure.Owing to saved the structure of the outer field combustion chamber cover of fuel holder cover, the combustion bavin places in the fuel holder cover during use, and the air inlet pore intake is big, the heat that firewood combustion produces can be fast by furnace shell to indoor transmission, be particularly suited for warming.
As a kind of improvement of the present utility model, a side suitable for reading of described truncated cone-shaped body is provided with the back-fire relief flange a little more than periphery.This structure can stop duration and degree of heating, reduces the thermal loss that duration and degree of heating directly enters flue.
The another kind of improvement is also to comprise the charging breach that is positioned at described back-fire relief flange one side.Adopt this structure to be complementary, be convenient to add fuel with the furnace shell that is provided with the charging side door.
Employing the utlity model has following advantage:
1, combustion chamber adopts the integral type design, and is simple and reasonable, is convenient to make and install.
2,, thereby reduced the production cost about 40% of combustion chamber owing to saved the structure of the outer field combustion chamber cover of fuel holder cover.Compare with the wood stove core that was provided with the combustion chamber cover originally, each combustion chamber can have been saved the heavily about 2.5kg of ironcasting, about 13 yuan of cost saving.
3, owing to the combustion chamber reasonable in design, its sufficient combustion, thermal efficiency height has been realized smokeless combustion substantially.Because intake is big, firewood combustion is abundant, and the air return stove energy-saving effect is not fully exerted, and its more conventional Firewood burning stove kitchen range is economized bavin more than 70%.
4, firepower is concentrated, and strong and powerful, the speed of cooking of heating up water is fast, and heating is held concurrently and cooked, and convenient and practical, environmental sanitation is comfortable.
5, its optimum range is wide, and dried firewood, wet bavin, straw, chaff shell, sawdust all can use, and its combustion efficiency is similar to burning coal air return stove.
6, its a kind of improved procedure can add fuel from side door, uses more convenient.
Marginal data
Below in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is a kind of embodiment perspective view of the utility model.
Fig. 2 is the installment state schematic diagram of the utility model in body of heater.
Fig. 3 is the A-A cross-sectional schematic (the fuel holder cover partial structure of showing combustion chamber) of Fig. 2.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of embodiment of the utility model comprises fuel holder cover 1, described fuel holder cover 1 comprises the cover mouth 2 and the cover end 3, its cover mouth 2 is big, the cover end 3 is less, the cover wall 4 of described fuel holder cover 1 and the cover end 3, are provided with some air inlet pores 5, also comprise the fire casing 6 that extends upward from the cover mouth 2 of described fuel holder cover 1, described fire casing 6 comprises truncated cone-shaped body 7, and described fuel holder cover 1 is integral structure with described fire casing 6.Owing to saved the structure of fuel holder cover 1 outer field combustion chamber cover, during use, the combustion bavin places in the fuel holder cover 1, and air inlet pore 5 intakes are big, the heat that firewood combustion produces can be fast by furnace shell to indoor transmission, be particularly suited for warming.
To shown in Figure 2, as a kind of improvement of the present utility model, a side suitable for reading of described truncated cone-shaped body 7 is provided with the back-fire relief flange 8 a little more than periphery as Fig. 1.This structure can stop duration and degree of heating, reduces the thermal loss that duration and degree of heating directly enters flue.
As shown in Figure 1, 2, the another kind of improvement is also to comprise the charging breach 9 that is positioned at described back-fire relief flange 8 one sides.This structure can be complementary with the furnace shell that is provided with the charging side door.
The utility model is not limited to the concrete structure of the foregoing description, and the equivalent transformation of other homogeneous structure all falls within the protection domain of the present utility model.
