Description

Close type fireplace

Technical field

The utility model relates to a kind of fireplace, especially adopts the close type fireplace of wooden shot band self-feeding.

Background technology

Existing main structure of fireplace is made up of combustion chamber and base, its opening is arranged on the combustion chamber, towards an indoor side, top of combustion chamber is provided with outlet port, be with manually fuel being sent in the combustion chamber by opening during use, the heat that burning produces then is delivered to indoor by natural radiation, the cold air in the heating clamber raises indoor temperature.

The fireplace that heating of house the is used waste gas of discharging that need prevent to burn is drained into indoor, therefore the opening part transfer the fuel from the combustion chamber makes the waste gas of the inside enter into indoor easily, cause the pollution of room air, and adopt artificial interpolation fuel also dangerous, the air supply system of combustion chamber also is relevant with opening, there is not other ventilation shaft, the heat that produces also is to adopt radiation, and the area that distributes is not extensive, and careat is big, the place of distance, the DeGrain of intensification.

Summary of the invention

The utility model has solved to be needed in the prior art opening of combustion chamber is opened artificial interpolation fuel, and dangerous also inconvenient shortcoming provides a kind of and indoor airtight, only blows out the close type fireplace that hot blast makes indoor intensification by the blowing pipeline.

The utility model has also solved does not have ventilation shaft in the prior art, cause burning insufficient, the bad shortcoming of indoor remote local intensification effect, independently ventilation shaft of a kind of employing is provided, heat can be dispersed into indoorly by the blowing pipeline, improve the close type fireplace of intensification effect than distant positions.

A purpose more of the present utility model provides a kind of timber that adopts branch, leaf, cornstalk etc. to make as raw material and acts as a fuel, and cost is low, the close type fireplace that economic benefit is high.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of close type fireplace, comprise burner hearth, dyestuff conveying device and automaton, be provided with ventilation shaft and combustion chamber in the burner hearth, wherein, ventilation shaft comprises exhaust duct, fresh wind tube and blowing pipeline; Exhaust duct is in the blowing pipeline; The burner hearth front is provided with the fire door of fixing seal, and fire door is a multilayer sheet metal frame structure, the intermediate layer devitrified glass; Be provided with the stove box in the described combustion chamber, the stove box links to each other with the heating muff that inside is provided with heating rod; The blowing pipeline is provided with warm-air pipe, and the outer wall of warm-air pipe contacts with the combustion chamber, and inwall communicates with the blowing pipeline.Close type fireplace is provided with independently ventilation shaft, waste gas that the combustion chamber produces and residue are discharged outdoor by exhaust duct, can not impact indoor, the fresh wind tube road can provide air sufficient in the combustion chamber to burn, on the blowing pipeline warm-air pipe that is exposed in the combustion chamber is set, make the heat of generation indoor except radiation is dispersed into, also can blow to indoor position far away by the blowing pipeline, it is more even that indoor temperature is raise; The fire door in burner hearth front is a multistory frame structure, and the intermediate layer adopts devitrified glass preventing to improve radiation effect when the inside waste gas from revealing, and devitrified glass is transparence, can observe inner burning, improves appreciation effect; The periphery sealing of fire door is adopted the alumina silicate band to inlay and is formed, and the heat resistance of devitrified glass can reach more than 1000 degree; By the automatic control of fuel delivery means, realize carrying out automatically the interpolation of fuel; The waste gas that exhaust duct is discharged has heat, and the blowing pipeline can utilize the heat of waste gas in the exhaust duct to heat air in the blowing pipeline when blowing.
