Abstract

The utility model relates to a household two-purpose stove for cooking and heating, which comprises a combustion chamber, a water jacket stove wall and a chimney with a water jacket. The combustion chamber is divided into an upper combustion chamber and a lower combustion chamber through an upper fire grate and a lower fire grate. The two sides of the lower combustion chamber are provided with symmetric smoke and fire passages. The smoke and fire passages are communicated with a heating chamber arranged above the upper combustion chamber. The upper openings of the smoke and fire passages and an upper opening of the upper combustion chamber are respectively covered by a fire sealing cover. The back part of the heating chamber is communicated with a lower opening of the chimney through the smoke and fire passages. Heat pipes are uniformly distributed on the periphery of the chimney. The upper parts of the heat pipes are positioned in the water jacket of the chimney, and the lower parts of the heat pipes are positioned on the exits of the smoke and fire passages. The utility model causes the combustion coal to be sufficiently combusted, fully utilizes the residual heat of the fume to continuously heat the hot water in the water jacket and has the advantages of high heat efficiency, no black smoke overflow and pollution reduction.

Description

The household cooking and warming dual-purpose stove

The utility model relates to for family makes meal, the dual-purpose coal furnace of heating, particularly household cooking and warming dual-purpose stove.

The widely used coal-fired cooking-heating dual-purpose stove tool of vast urban and rural residents, the water jacket furnace wall of its body of heater is communicated with chimney water sleeve, combustion system just belongs to and burns, coal-fired in the burner hearth internal combustion, flue gas is discharged by chimney, the fired coal combustion liberated heat is with the heating of the water in water jacket furnace wall and the chimney water sleeve, and heated hot water can supply heating, sits pot and can cook above burner hearth.Weak point is that burning of coal is abundant inadequately, and the thermal efficiency is low, and the flue dust of discharge is big, contaminated environment.

The purpose of this utility model is to provide a kind of household cooking and warming dual-purpose stove, not only can make meal and supply heating, and can make the fire coal in the burner hearth fully burn thermal efficiency height, the waste heat that can also make full use of flue gas continues the hot water among the heating water jacket, has improved heat exchange efficiency.

The utility model is achieved in that a kind of household cooking and warming dual-purpose stove, comprise the combustion chamber, water jacket furnace wall and the chimney that has water jacket, the perisporium of body of heater is the water jacket furnace wall, by last fire grate and following fire grate the combustion chamber is separated into upper combustion chamber and lower combustion chamber, be provided with the smoke flue of symmetry in the both sides of lower combustion chamber, smoke flue is communicated with the heating clamber of upper combustion chamber top, on smoke flue is suitable for reading, be stamped fire sealing cover respectively, at the fire sealing cover that is stamped suitable for reading of upper combustion chamber, the rear of heating clamber is communicated with the chimney end opening by flue, is evenly equipped with heat pipe around chimney, the top of heat pipe is arranged in the chimney water sleeve, and the bottom of heat pipe is arranged on the exit of flue.

When the utility model uses, at first open the fire sealing cover of smoke flue setting suitable for reading, cover upper combustion chamber's fire sealing cover suitable for reading, light fuel in the upper combustion chamber by water inlet again with being full of water in the furnace water jacket, the unburnt fuel of upper combustion chamber falls to lower combustion chamber and burns away, fuel is fully burned, saved the energy, improved the thermal efficiency, enter the heat pipe of the flue gas elder generation heating chimney end opening of chimney from flue, heat pipe has improved heat exchange efficiency with the water in the heat transferred chimney water sleeve, and heated hot water connects the heating system heating by delivery port in the water jacket.When needs are made meal, cover smoke flue fire sealing cover suitable for reading, open the fire sealing cover of upper combustion chamber on suitable for reading, can sit pot and make meal, at this moment stove fire is just become by anti-burning and burns, and firepower is concentrated, the flame temperature height, and still can provide heating hot water as usual.

Fig. 1 is an A-A cutaway view of the present utility model, and Fig. 2 is a B-B cutaway view of the present utility model, and Fig. 3 is a C-C cutaway view of the present utility model.Below in conjunction with accompanying drawing the utility model is further described, a kind of household cooking and warming dual-purpose stove, comprise the combustion chamber, water jacket furnace wall and the chimney that has water jacket, the perisporium of body of heater is that water jacket furnace wall (1) is provided with water inlet (18) at the side-lower of body of heater, by last fire grate (6) and following fire grate (10) combustion chamber is separated into upper combustion chamber (4) that has fire door (5) and the lower combustion chamber (7) that has fire door (8), last fire grate (6) is the water pipe that two ends are communicated with water jacket, be provided with ventilation deashing chamber (11) in the below of lower combustion chamber (7), be provided with the smoke flue (9) of symmetry in the both sides of lower combustion chamber (7), smoke flue (9) is communicated with the heating clamber (2) of upper combustion chamber (4) top, on smoke flue (9) is suitable for reading, be stamped fire sealing cover (17) respectively, the fire sealing cover (3) that is stamped suitable for reading in upper combustion chamber (4), the rear of heating clamber (2) is communicated with the end opening of chimney (12) by flue (16), in flue (16), be provided with at least two and be communicated with water pipe (15), the upper end that is communicated with water pipe (15) is communicated with upper water sleeve furnace wall (1), the lower end that is communicated with water pipe (15) is communicated with the water jacket furnace wall (1) of bottom, around chimney (12), be evenly equipped with heat pipe (14), heat pipe (14) is the metal tube of sealed at both ends vacuum, seamless steel pipe preferably, the distilled water of heat-transfer working medium heat-transfer working medium for being made in proportion of some is housed in the heat pipe (14) of sealed vacuum, vinegar, liquor, the mixture of chlorination toluene sodium, the top of heat pipe (14) is arranged in the chimney water sleeve (13), and the bottom of heat pipe (14) is arranged on the exit of flue (16).Heat pipe (14) is in working order the time, because the boiling point of heat-transfer working medium is very low, become gas immediately after running into heating, the gas band heat and is risen, by heat pipe (14) wall with the water in the heat transferred chimney water sleeve (13), after the gas heat release, become liquid and flow to heat pipe (14) bottom, become gas after being heated and carry heat and rise, the heat transfer that moves in circles is provided with hot water outlet (19) at the upside of chimney water sleeve (13).
