Abstract

The utility model relates to a household heating stove comprising a chimney (1), a water jacket, a fin (3), a stove ring flat cover (4), a portfire (5), a heat insulation layer (8), a stove door (9), an ash bucket (10), a fire passing ring (11), a flame retardant layer (12), a movable stove grate (13), a stove casing (14), a heat increasing cover (15), a water inlet pipe (17) and a water outlet pipe (18). The household heating stove is characterized in that the water jacket is composed of an upper hearth water jacket (6) of a four-bevel pipe, a lower hearth water jacket (7) of the four-bevel pipe, and a flue water jacket (2); a movable windscreen arranged on the heat increasing cover can regulate flue suction. The household heating stove can be use for cooking, heating and showering, and has the advantages of large heat exchange areas, high heat efficiency, material saving and labor saving.

Description

The domestic heating stove

The utility model relates to a kind of domestic heating stove.

The domestic heating stove that existing market is sold as: Sang Pulu (ZL90200056.X) is made up of shell, cyclic water jacket, furnace lining, grate, flue, insulation material, the inner chamber that it is characterized in that cyclic water jacket is established the water conservancy diversion rib, processed complex, the radiation heat transfer area of burner hearth top is less, flue does not have water jacket exhaust gas temperature height, the inabundant heat exchange of flue gas is just drained, and has reduced the thermal efficiency.

The purpose of this utility model is to provide a kind of heat exchange area big, makes simple domestic heating stove.This stove can also be regulated the flue draft.

The utility model adopts truncated rectangular pyramids pipe water jacket to increase heat exchange area, because the circle that diameter is identical with the square length of side, its girth that is to say the lateral area of cylindrical side area less than quadrangular less than foursquare girth, and the quadrangular stove is bigger than the heat exchange area of cylindrical stove thus.

The utility model comprises chimney, water jacket, fin, stove circle flat cover, portfire, heat-insulation layer, fire door, ash bucket, crosses pyrosphere, flame retardant coating, moving grate, furnace shell, heating cover, water inlet pipe, outlet pipe.Described water jacket is by truncated rectangular pyramids pipe upper furnace water jacket, truncated rectangular pyramids pipe lower hearth water jacket, and the flue water jacket constitutes.

One movable windscreen is housed on the described heating cover.

The utlity model has following advantage:

1. water jacket of the present utility model adopts two truncated rectangular pyramids pipes to form the water jacket of square " vase " formula, and is bigger than the column type water jacket heating surface area of same size.The utility model heating area is 100m ²The stove floor space be 80m than heating area on the market ²The stove floor space little, and highly low.

2. because stove adopts the truncated rectangular pyramids shape, processing does not need rotary machine, has reduced processing cost.

3. owing to strengthened the water jacket area of upper furnace, and be welded with the tilting V-type fin of a circle on this surface, water jacket place with steel, can absorb the radiant heat in the stove in a large number, the V-type fin changes the flow direction of inner flue gas of the stove simultaneously, strengthened the heat convection between flue gas stream and the heating surface, increased and exerted oneself.

4. owing on heating cover, increased movable wind shelves,, can regulate temperature and be used for banking up a fire night by regulating the flue draft.

5. stove can not only be used for heating, can also be used for cooking, wash dry.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the utility model structural representation.

Fig. 2 is heating cover and a movable wind shelves schematic diagram in the utility model.

Fig. 3 is the schematic diagram of portfire.

As shown in the figure, 1 is chimney, and 2 is the flue water jacket, and 3 is the V-type fin, 4 is stove circle flat cover, and 5 is portfire, and 6 is truncated rectangular pyramids pipe upper furnace water jacket, 7 is truncated rectangular pyramids pipe lower hearth water jacket, and 8 is heat-insulation layer, and 9 is fire door, 10 is ash bucket, and 11 was pyrosphere, and 12 is flame retardant coating, 13 is moving grate, and 14 is furnace shell, and 15 is heating cover, 16 is movable wind shelves, and 17 is water inlet pipe, and 18 is outlet pipe.

The water jacket of stove is made of truncated rectangular pyramids pipe upper furnace water jacket 6, truncated rectangular pyramids pipe lower hearth water jacket 7 and flue water jacket 2; Movable windscreen 16 is housed on the heating cover 15.

When heating, put heating cover 15, lid upper furnace ring flat cover 4, and open fire door 9 when needing to strengthen the heating temperature, turns over movable windscreen 16 on heating cover 15, this moment the flue non-resistance, the flue draft increases, the furnace temperature increase.

Flue gas flow is: coal is from stove circle flat cover 4, through upper furnace, cross pyrosphere 11 and add lower hearth, air is after fire door 9, moving grate 13 enter the burner hearth burning, from crossing 11 mouthfuls of ejections of pyrosphere, after heating cover 15 stopped, the annular space that flow through truncated rectangular pyramids pipe upper furnace water jacket 6 and V-type fin 3 are formed entered chimney 1 emptying.

The flow process of water is as follows: backwater in the radiator, and enter truncated rectangular pyramids pipe lower hearth water jacket 7 from water inlet pipe 17 and enter truncated rectangular pyramids pipe upper furnace water jacket 6 then, enter flue water jacket 2 at last and enter heating system once more from outlet pipe 18.

When being used for cooking, take off heating cover 15, stove circle flat cover 4, put into portfire 5, flue gas is through portfire 5 ejections, and from chimney 1 emptying, the flow process of water is as mentioned above.

When banking up a fire, cover heating cover 15, stove circle flat cover 4 and put down movable windscreen 16, movable windscreen 16 is gapped with flue, can reduce the chimney draft when movable windscreen 16 puts down.
