Abstract

The utility model relates to an energy-saving heating stove which is composed of a stove casing, a stove core, a water storage chamber, a waste heat chamber, an ash bucket, a stove grate, a heating chamber, a water supply pipe, a water return pipe, a stove plate and a flue. The utility model is characterized in that a plurality of smoke outlet passages are arranged on the circumjacent walls of a burning chamber; a plurality of side flues are also arranged on the upper part of the stove core and the circumference of a stove opening. The utility model makes full use of the heat energy and the waste heat of the fume gas in coal combustion and has the advantages of scientific, unique and reasonable structural design, coal saving, high heat efficiency and quick temperature rise. The cooking and heating can be carried out at the same time, which achieves the purpose of one furnace with multiple functions and saves cost.

Description

The energy-saving heating stove

The utility model relates to a kind of coal furnace of using that can heat and can heat up water and cook more.

At present, central heating for various reasons, is still failed to realize so far in most of area of China, and warming still adopts common coal stove mostly, and this coal stove can only solve the local heating problem of placing in the stove room; To this, also once the someone developed a kind of heating stove (being commonly called as native heating installation), and it can solve the heating problem of suite, but it exists coal consumption big again, can only single solution heating problem, and can not heat up water simultaneously, cook.So still can not get the public's approval so far, fail penetration and promotion.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of heating problem that both can effectively solve suite is provided, and can heat up water simultaneously again, cook, and thermal efficiency height.The consumption coal is few, and energy savings is used again easily heating stoves of using more.

The technical solution of the utility model is: this heating stove comprises furnace shell (8), the ash bucket (13) of furnace shell (8) bottom one side, return pipe (19), furnace shell (8) center is flue (9), fire grate (12) is arranged at the bottom of flue (9), fire grate (12) is gone up the attaching tooth (20) of scratching in the ashes, the periphery of flue (9) is water storage room (15), the outer ring of water storage room (15) is waste heat chamber (10), the bottom of waste heat chamber (10) is heat-insulation layer (11), the top of flue (9) is fire door (16), has several side flues (6) around the fire door (16), and the top of fire door (16) is hollow round table-like heating clamber (5), have several smoke ducts (7) on all around wall of heating clamber (5), the upper side of furnace shell (8) has flue (17), upper hose (18), and stone or metal plate for standing a stove on as a precaution against fire (1) is arranged at the top of furnace shell (8), outer bell (2), inner roof brick (3); On fire door (16), also can join a fire sealing cover as required in addition.

Advantage of the present utility model and effect are: owing to have some smokes duct (7) on all around wall of combustion chamber (5), also have several side flues (16) around the fire door (16), increased the heating surface area of water storage room, the hot cell (10) because the utility model design is had a surplus again, make cigarette before flue (17) is discharged, can waste heat be passed to water storage room (15) in that waste heat is indoor, improve or keep the temperature of water in the water storage room (15), because the unique reasonable structural design of the utility model, the heat energy that has produced when having made full use of coal combustion and the waste heat of flue gas, so this stove has thermal efficiency height, temperature waterborne is fast, can realize multi-use, not only economy but also material benefit.

Characteristics of the present utility model and being also advantageous in that: also can be equipped with a fire sealing cover (4) on the fire door (16), temperature is too high in the too high or room when the water temperature in the water storage room (15) when not needing to heat again, fire sealing cover (4) can be buckled on the fire door (16), this moment, flue gas can only be emerged from side flue (6), coal in the flue (9) just can not fully burn this moment, thereby prolonged the burning of coal time, be sparing in the use of coal, main is has controlled the water temperature of water storage room (15) and has regulated the room temperature, when room temperature is crossed low maybe need use hot water the time, only need fire sealing cover (4) is taken off on fire door (16), coal in the flue (9) just can fully burn again, and inner temperature of room increases with the water temperature in the water storage room (15) and increases.

Fig. 1 is a longitudinal sectional drawing of the present utility model.

Fig. 2 is a transverse cross-sectional view of the present utility model.

As Fig. 1, Fig. 2, in upper hose (18) injects water water storage room (15), take away inner roof brick (1) and outer bell (2) and fire sealing cover (4), in burner hearth (14), add coal, ignite behind the coal, just pot or kettle can be placed on the stone or metal plate for standing a stove on as a precaution against fire (1) and cook, heat up water, flue this moment (9) just partly passes to water storage room (15) with the heat energy that coal combustion produced, the flue gas part that coal combustion produces directly enters in the heating clamber (5) from fire door (16), another part enters heating clamber (5) through side flue (6), and the entrained heat of flue gas this moment is partly passed to water storage room (15) by side flue (6), and the flue gas smoke duct (7) on heating clamber (5) wall more directly discharges or discharges after waste heat chamber (10), the overall process of fume emission, all the time the flow through locular wall of water storage room (15), enlarge heating surface area like this, slowed down the speed that flue gas is discharged, thereby prolonged the time of contact of flue gas and water storage room (15) locular wall, improved the thermal efficiency, made the water quick heating in the water storage room (15).

Claims
