Abstract

The utility model discloses a domestic energy economizing stove, comprising a core of furnace, a secondary inlet duct, a flue, a tank, a chimney, an upper and a lower cap plates, a fire-bars supporting foot and a casing, wherein,. The secondary inlet duct, the flue, the tank and the casing are provided surround the core of furnace, and the chimney is positioned under the core of furnace and the tank. The utility model has the advantages of simple manufacturing process, low cost, and strong applicability, which can be used for burning various coal, wood, combustion gas and electricity.

Description

Domestic energy economizing stove

The utility model is a kind of home furnace.

At present, the home furnace of disclosed use is common all to be to adopt an air intake, and chimney then is positioned at the top of cooking stove.It is insufficient that so structure can make fuel combustion, and firepower is not prosperous, and during chimney draught, firepower can be taken out and hold, and the thermal efficiency is reduced.Chinese patent application CN85202280u discloses the double-deck burner hearth of a kind of twice aeration, it is that secondary ventilating ducting and burner hearth are constituted an integral body, secondary ventilating ducting is made up of several ducts, the duct extends axially the appropriate location, upper end by the burner hearth lower end edge and turns in the burner hearth again, and the inner edge thickness at place, duct is greater than the thickness of outside, though this kind structure has secondary air, but because ventilating duct is positioned in the middle of the burner hearth, and burner hearth generally all is to adopt the material of poor thermal conductivity to manufacture, thereby making that the temperature of secondary air is lower, combustion-supporting effect is relatively poor.

The purpose of this utility model aims to provide and a kind ofly can make full use of flue residue heat, improves the thermal efficiency, has secondary air and manufacture easy cooking stove.

Cooking stove described in the utility model is by combustion chamber, secondary air road, flue, water tank, chimney, upper and lower cover plate, fire bars, feet and outer cover constitute, wherein the secondary air road, flue water tank and outer cover are successively in the periphery of combustion chamber, and chimney then is positioned at the bottom of combustion chamber and water tank.

Above-mentioned cooking stove is the bottom that chimney is loaded on stove, so just can utilize the waste heat of flue to come as thermal source, but the both water in the heating water tank can heat the air of coming in the secondary air road again, makes it to become high-temperature hot-air, plays good combustion-supporting effect.

Fig. 1,2,3,4 constitutes a kind of embodiment of the present utility model.

Cooking stove described in the utility model, be provided with secondary air road (4) flue (1) in the outside of combustion chamber (3) and be in close proximity to secondary air road (4) and water tank (2), fire bars (5) is movable, be used to support combustion chamber (3), discharge body of heater from the cigarette that flue (1) is come in by annular outlet flue (6) to chimney (7), one cigarette ash sprue (16) is arranged at the bottom of annular outlet flue (6), relative with it is fire door (9), can remove cigarette ash by fire door and cigarette ash sprue (16), the available bolt of bottom plate (13) is connected with body of heater, so that dismounting, feet (14) can directly be welded on the bottom plate (13), and upper cover plate (11) is movable, in order to make combustion chamber (3) fine location in stove, after it installs, be fixed by alignment pin (15),, improve the thermal efficiency in order to make full use of waste heat, annular conduit (8) can also be increased, so that utilize steam on cooking stove top.

In such an embodiment, the wall in secondary air road (12) can separate with the wall of water tank to be manufactured, but when assembling, wall (12) should seal with the intersection of water tank wall, in order to avoid leak cigarette or down draught, this sealing can be adopted provisional sealing, as applying etc. with mud is stifled, so that dismounting, the outer wall of water tank can directly utilize cooking stove shell (10).

Fig. 5,6,7 has constituted another kind of embodiment of the present utility model.

Be to adopt above-mentioned cooking stove to burn combustion gas in this kind embodiment, as shown in Figure 5, gas combustion apparatus (18) is placed combustion chamber (3), on the fire bars (5), secondary air road (4) is in close proximity to combustion chamber (3), in this example, water heater adopts circulating water pipe (17), and the space between circulating water pipe (17) promptly can be flue.

In this kind embodiment, because the existence of flue, can make full use of this part waste heat on the one hand, water in the heat cycles water pipe, all can from flue, discharge by the various smells that combustion gas brought on the other hand, if gas combustion apparatus has leakage slightly, the combustion gas that is spilt also can be discharged from flue, avoids causing danger.Present employed gas combustion apparatus is behind the water boil in the pot; usually can overflow and make fray-out of flame, greatly reduce safety coefficient, perhaps burn panhandle hot; for operation is made troubles; when using the described this cooking stove of present embodiment, just can avoid the generation of above-mentioned situation, and this circulating water pipe of use present embodiment; can utilize waste heat; supply with hot water continuously, both saved the energy, the thermal efficiency is improved.

Energy-saving cooking with the present design manufacturing, because its structure is taked local independent moulding, and organic composition one, not only be conducive to dismounting, and guaranteed the steadiness that it is whole, this kind cooking stove does not all have specific (special) requirements to material and manufacturing equipment, manufacturing process is simple, cost is low, can be used for burning various coals, bavin, combustion gas, electricity etc., and applicability is strong.

Claims
