Abstract

Provided is an internal and external double-sleeve insulation furnace core, relating to a furnace core. An upper end in an external furnace core (4) is provided with a shrinking upper port (1); an inner step (2) is provided under the upper port; the lower part of the inner step is an inner wall (3) of an outer furnace core; a lower end of an inner core outer wall (5) of an inner furnace core (6) is provided with an outer protruding ring (8); an outer step (7) is provided above the outer protruding ring; a lower end of the outer furnace core is against on an upper end face of the outer protruding ring of the inner furnace core; the upper end of the inner furnace core is against on a surface of a lower part of the upper port; a gap (9) is formed between the upper end of the outer step of the outer furnace core and the outer step of the inner furnace core to form an insulation structure. According to the utility model, a present furnace core is divided into internal and external layers; the gap between the outer furnace core and the inner furnace core forms an insulation structure to realize rapid heating each time of making a fire or opening a fire cover.

Description

A kind of inside and outside two cover insulation combustion chambers

[technical field]

The utility model relates to a kind of combustion chamber, especially a kind of inside and outside two cover insulation combustion chambers.

[ Background technology]

Known; The operation principle of coal furnace is: coal briquette is placed in the cavity of combustion chamber; Slag notch by the bottom gets into air to fire coal comburant oxygen to be provided; The coal-fired heat energy that is produced through burning is by the gap of generation between the strong point on coal furnace top and the pot, heat energy along the bottom of a pan to around distribute heating kettle the bottom; Wherein is connected through filler around the combustion chamber with between the furnace wall, owing to be entity around the combustion chamber, so light a fire or when opening fiery the lid, it is slower to heat up, and influences the use progress at every turn.

[summary of the invention]

In order to overcome the deficiency in the background technology; The utility model discloses a kind of inside and outside two cover insulation combustion chambers; Said inside and outside two cover insulation combustion chambers are through two-layer inside and outside existing combustion chamber is divided into; Utilize the gap between outer combustion chamber and the inner stove core to form insulation construction, realized lighting a fire or the purpose that is rapidly heated when opening the fire lid at every turn.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of inside and outside two cover insulation combustion chambers comprise outer combustion chamber and inner stove core, and the inner upper end of said outer combustion chamber is provided with the suitable for reading of reducing, is provided with interior step in bottom suitable for reading, and said interior step bottom is the inwall of outer combustion chamber; The interior outer core lower end of said inner stove core is provided with outer outstanding ring, and the top of outer outstanding ring is provided with outer step; The lower end of outer combustion chamber withstands on the outstanding outward upper surface of encircling of inner stove core, and the upper end of inner stove core withstands on the face of bottom suitable for reading, is the gap between the outer step of the outer step upper end of combustion chamber and inner stove core outside, and said gap forms insulation construction.

Described inside and outside two cover insulation combustion chambers, the exterior face of said outer combustion chamber is circle or polygonal.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The said inside and outside two cover insulation combustion chambers of the utility model, by combustion chamber being divided into the inside and outside two-layer of inner stove core and outer combustion chamber, by the outer step and the outer outstanding ring of inner stove core, the suitable for reading and interior step of outer combustion chamber forms supporting construction; The utility model utilizes the gap to form insulation construction, has realized lighting a fire or the purpose that is rapidly heated when opening the fire lid at every turn.

Fig. 1 is the outer combustion chamber and the inner stove core sleeve structure sketch map of the utility model;

Fig. 2 is the outer combustion chamber and the inner stove core combination back structural representation of the utility model;

Fig. 3 is the perspective view of the utility model;

Among the figure: 1, suitable for reading; 2, interior step; 3, inwall; 4, outer combustion chamber; 5, interior outer core; 6, inner stove core; 7, outer step; 8, outer outstanding ring; 9, gap.

[specific embodiment]

Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope;

Inside and outside two cover insulation combustion chambers in conjunction with described in accompanying

drawing

1,2 or 3 comprise outer combustion chamber 4 and inner stove core 6, and the inner upper end of said outer combustion chamber 4 is provided with the suitable for reading 1 of reducing, and step 2 in suitable for reading 1 bottom is provided with, and said interior step 2 bottoms are the inwall 3 of outer combustion chamber 4; Interior outer core 5 lower ends of said inner stove core 6 are provided with outer outstanding ring 8, and the top of outer outstanding ring is provided with outer step 7; The lower end of outer combustion chamber 4 withstands on the upper surface of inner stove core 6 outer outstanding rings 8, and the upper end of inner stove core 6 withstands on the face of 1 bottom suitable for reading, is gap 9 between the outer step 7 of outer step 7 upper ends of combustion chamber 4 and inner stove core 6 outside, and said gap 9 forms insulation construction; The exterior face of said outer combustion chamber 4 is circle or polygonal.

Implement the said inside and outside two cover insulation combustion chambers of the utility model; By combustion chamber being divided into the inside and outside two-layer of inner stove core 6 and outer combustion chamber 4; Outer step 7 and outer outstanding ring 8 by inner stove core 6; Suitable for reading 1 of outer combustion chamber 4 forms supporting constructions with interior step 2, utilizes the gap formation insulation construction between the interior outer core 5 of outer combustion chamber inwall 3 and inner stove core 6; The utility model has been realized lighting a fire or the purpose that is rapidly heated when opening the fire lid at every turn.

The utility model does not detail part and is prior art.
