A smoke channel is arranged on the lower end of stove implements, a stove cavity as a fire wall keeps certain distance with the stove mouth, and a smoke gas passage is formed between the stove cavity and the stove outer housing. The smoke gas rises from the stove cavity to the stove mouth around, and then the smoke gas turns back downward, passing through the smoke gas passage between the stove cavity and the stove outer housing, to be discharged from the smoke channel under the lower end of the stove implements. The utility model has the advantages of unique structure, full utilization of heat energy, and quite obvious coal saving effect.

Description

Domestic energy-saving heating stove with back-fire function

The utility model relates to a kind of back-fire domestic energy-saving heating stove, is a kind of small-sized hot-water heating stove that is specifically designed to family expenses.

In the existing technology, be used for the small-sized hot-water heating stove of family, promptly native heating installation, varied, pluses and minuses are respectively arranged.All designs improve the stove of oneself per capita from each side in line with energy-conservation, as to reduce environmental pollution intention.What have utilizes the multilayer water jacket, and what have utilizes secondary wind, and what have utilizes water-gas, and what also have has all added water jacket or cyclic water jacket at flue, fire door, in order that make full use of energy.These technical schemes on Chinese utility model patent communique usually as seen.But the furnace gas flue in these schemes all is by orthodox practice flue to be located at the top of stove and accessory, and promptly flame rises and takes the useless gas of combustion away by flue in the burner hearth.But flue has also been taken a large amount of hot gas away simultaneously, and Here it is has a lot of designs to utilize the reason of flue heat.But flue is near the higher place of fire door fire cigarette temperature, and it is big to take heat away, and cigarette contains a lot of imperfect combustion gases, if device circulating water pipe in the flue, will be too big to the infringement of water pipe.

The purpose of this utility model is: design a kind of stove and accessory that makes full use of the flue heat, to reach the purpose of effectively utilizing the capacity of furnace.

Scheme of the present utility model is as follows: the lower end of flue being changed into stove outer covering, burner hearth discord fire door directly joins, burner hearth has a distance as fire division wall and fire door, in the time of near flame rises to fire door, return downwards to the flue of stove and accessory bottom again, and at stove outer covering and fire door all water jacket is set so that heat cycles water.One circle tubular type water jacket also can be set between the water jacket of stove outer covering and burner hearth, can utilize energy more fully.

Flue is arranged on the bottom of stove and accessory, after being risen, fiery cigarette near fire door, returns formation " back-fire " again downwards, whole stove outer covering and furnace saliva set have been heated, heat is utilized fully, water inlet pipe is located at the lower end of stove outer covering water jacket, and outlet pipe is located at the top of stove outer covering water jacket, and the Inlet and outlet water drop is big, also just needn't as the native heating installation horse that will dispel the heat like that get very highly, more effectively utilized heat.If add a circle tubular type water jacket again then better between burner hearth and stove outer covering water jacket, effect of coal saving is very obvious.

The drawings and Examples explanation:

Fig. 1 is the sectional structure chart of an embodiment of the present utility model, and Fig. 2 is that A-A is to view.

Embodiment 1:

Stove peripheral whole is a circle shell water jacket (6), and and furnace saliva set (2) communicate.Burner hearth (4) and fire door (3) and furnace saliva set (2) do not join, have one at interval, burner hearth and stove outer covering water jacket (6) form exhaust gases passes, after rising to fire door in the burner hearth, the fire cigarette returns downwards with the exhaust gases passes between burner hearth and the stove outer covering, to fire useless gas to flue (7) and take away, heat stove outer covering water jacket (6) and tubular type water jacket (5) simultaneously.Tubular type water jacket (5) is established a circle (as shown in Figure 2) in burner hearth (4) and the peripheral water jacket of stove (6), each pipe upper end and furnace saliva set (2) join, and the bottom of the peripheral water jacket of lower end and stove (6) communicates.Therefore, the stove of this back-fire formula, the heat that runs off in the flue are just seldom.Advance cold water pipe and be (10), outlet pipe is (1), and drop is big between the intake-outlet.Other, (9) are fire bars, (8) are boiler clothing (8).

Embodiment 2:

Can not establish the tubular type water jacket between burner hearth (4) and the stove outer covering water jacket (6).

Fig. 1 is a Figure of abstract.

Claims (2)

1, back-fire domestic energy-saving heating stove, fire door, stove outer covering constitute by water jacket, it is characterized in that flue is located at stove and accessory the bottom is arranged, be stove outer covering bottom, burner hearth has one at interval as fire division wall and fire door, space between burner hearth and the stove outer covering water jacket also is the circulation passage of fiery cigarette, and near the passage that fiery cigarette returns downwards burner hearth rises to fire door between burner hearth and stove outer covering water jacket is discharged by the flue that is located at the stove outer covering lower end.

2, back-fire domestic energy-saving heating stove according to claim 1, it is characterized in that furnace saliva set (2) and stove outer covering water jacket (6) communicate, the water inlet (10) of stove outer covering water jacket (6) at stove bottom, one tubular type water jacket (5) is arranged between burner hearth (4), the stove outer covering water jacket (6), the upper end of above-mentioned tubular type water jacket (5) and furnace saliva set (2) communicate, lower end and stove outer covering water jacket (6) communicate, and flue (7) is located at the lower end of stove outer covering water jacket (6).
