The purpose of this utility model is to provide a kind of domestic heating stove, not only makes fuel combustion abundant, the furnace temperature height, and quick heating, and also the furnace insulation performance is good, and thermal loss is few, thermal efficiency height, long service life.

The utility model is achieved in that kind of a domestic heating stove, comprise furnace shell, the ventilation deashing chamber, fire grate, burner hearth, chimney, assembling the lower hearth that refractory material constitutes on the inwall of the lower water jacket of garden tubular, on the outer wall of lower water jacket, be wrapped in heat-insulation layer, the inwall that is wrapped in the garden tubular upper water sleeve of heat-insulation layer on the outer wall constitutes upper furnace, the twice aeration band is being set between upper water sleeve and lower water jacket, uniform water pipe is communicated with upper water sleeve and lower water jacket, the air vent on ventilation deashing chamber top communicates with passage between furnace shell and the heat-insulation layer, the lower end that is distributed on the smoke flue in the upper water sleeve communicates with the twice aeration band, its upper end communicates with heating clamber, upper water sleeve is communicated with by the water jacket of water pipe with heating clamber top, accent wind dish is installed at the top of upper water sleeve, fire sealing cover is stamped at top at upper furnace, is stamped bell on the coal filling hole of the table that has heat-insulation layer.

Owing to all be added with insulation material in furnace shell of the present utility model and the table, can reduce scattering and disappearing of furnace heat, the lower hearth that is made of refractory material can prevent the lower hearth scaling loss, increase the service life, the twice aeration band and the fire sealing cover that are provided with can make full combustion of fuel, improve the thermal efficiency, and can regulate the size of intake by transferring the wind dish, easy to use.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is for transferring wind dish cutaway view, and Fig. 3 is for transferring wind dish vertical view.Below in conjunction with accompanying drawing the utility model is further described, a kind of domestic heating stove comprises furnace shell (4), ventilation deashing chamber (23), stove bamboo trunk (14), burner hearth, chimney (3), assembling the lower hearth (12) that refractory material constitutes on the inwall of the lower water jacket of garden tubular (11), uniform the guide groove of up/down perforation on the inwall of the lower hearth of garden tubular (12), guide groove can be beneficial to ash discharge and ventilation, impel coal-fired burning rapidly, on the outer wall of lower water jacket (11), be wrapped in heat-insulation layer (6), the inwall that is wrapped in the upper water sleeve (7) of heat-insulation layer (6) on the outer wall constitutes upper furnace (5), between upper water sleeve (7) and lower water jacket (11), twice aeration band (10) is being set, twice aeration band (10) communicates with passage between furnace shell (4) and the heat-insulation layer (6) for uniform air vent on the sidewall of annular, can make and enter the furnace air preheating, improve the thermal efficiency, make full combustion of fuel, air vent on the twice aeration band (10) also can be directly communicates with air vent on the furnace shell, uniform water pipe (9) is communicated with upper water sleeve (7) and lower water jacket (11), the air vent on ventilation deashing chamber (23) top communicates with passage between furnace shell (4) and the heat-insulation layer (6), the housing of ventilation deashing chamber (23) is provided with fire door (24), the lower end that is distributed on the smoke flue (8) in the upper water sleeve (7) communicates with twice aeration band (10), its upper end communicates with heating clamber (16), upper water sleeve (7) is crossed water pipe (22) and is communicated with the water jacket (25) on heating clamber (16) top, accent wind dish (20) is installed at the top of upper water sleeve (7), transfer the centre bore of wind dish (20) to match with the external part of the inwall of upper water sleeve (7), transferring wind dish (20) to go up uniform wind adjusting hole matches with smoke flue (8) hole on the upper water sleeve (7), on the last plane of transferring wind dish (20), linking wind adjusting rod (21), the handle of wind adjusting rod (21) is arranged on the outside of furnace shell (4), the handle of push-and-pull wind adjusting rod (21), transfer wind dish (20) to rotate along the external part of upper water sleeve (7) inwall, to regulate the size of air quantity, be stamped fire sealing cover (17) at the top of upper furnace (5), cover fire sealing cover (17) and can make full combustion of fuel, improve the thermal efficiency, on the coal filling hole of the table that has heat-insulation layer (18) (19), be stamped bell (15), chimney (3) is wrapped in the chimney water sleeve (2), can make full use of the waste heat of discharging flue gas and heat the water that chimney water sleeve (2) dashes, water inlet (13) is located at the bottom of furnace shell (4), and delivery port (1) is located at the top of chimney water sleeve (2).
