Description

The coal electric furnace

(1) technical field

The utility model relates to a kind of cooking or fire coal electric furnace.

(2) background technology

Present stove and accessory is generally coal, the single stove of using of electricity, when using coal stove, need light a fire with combustible, and the duration of ignition is long, the smoke pollution environment; For few igniting, adopt the method for banking up a fire to expend coal again; In the cooking,, add charcoal and too many or too much for use again, waste energy in needs short time during vigorous fire; When the coal fast burn burnt down, caloric value was not enough, does not reach application target, abandoned and still had surplus heat availablely, caused and used waste; Coal burning is incomplete, and the coal gas that discharges from coal when particularly burning is discharged in the air, both wastes energy, again contaminated air.Only use electric furnace, often do not reach instructions for use again.

(3) utility model content

The utility model is at the above-mentioned deficiency of existing stove and accessory, but provide a kind of adopt electric ignition, not only can make coal stove but also can do electric furnace also the coal electricity shared, can satisfy the cooking heating to different firepower needs, burning fully, the novel stove and accessory of high, the environmental protection of the thermal efficiency.

The technical scheme that realizes the utility model purpose is: it comprises furnace shell, Lu Quan, thermal insulation layer, ash drawing port, base, it is sleeved on together liner and combustion chamber, the end liner that seals, support the grate frame at the grate frame of combustion chamber and liner lower end, electric furnace in the grate frame or grate frame in addition in thermal insulation layer, leave the gap between combustion chamber and the liner, combustion chamber has pore from bottom to top, the grate frame divides two-layer up and down, the periphery on upper strata have with combustion chamber and liner between the hole that is communicated with, gap.When igniting and coal electricity are shared, in the grate frame, place electric furnace, when burning coal only, the taking-up electric furnace, the grate frame seals on grate frame flap.

In order to realize its purpose better, on the stone or metal plate for standing a stove on as a precaution against fire of electric furnace, have passage.The effect of perforate is to change existing electric furnace to only depend on radiant heat transfer be that radiation adds convection heat transfer' heat-transfer by convection on electric furnace pan, improves the thermal efficiency, particularly when electric furnace is used to light a fire, because hot gas rises, makes the igniting effect better.

Because the said structure of coal electric furnace during use, is opened the ash drawing port lid, plugs in, the electric furnace heating realizes electric ignition; The air that enters from ash drawing port in the burning, a part enters body of heater, the burning of coal supply charcoal, another part enters the gap between combustion chamber and the liner from the hole on grate frame upper strata, hole from the combustion chamber enters body of heater from different height again, coal gas that discharges from coal during so that burn and the carbon dust that rises with hot gas obtain sufficient oxidizing fire, can improve the thermal efficiency and the pollution that reduces environment of coal greatly; When the coal burning in the stove soon to the greatest extent the time or firepower when strong inadequately, culinary art at this moment or heating need the very hot oven of short time again, and coal can burn again, electric furnace can be put on grate frame or the stove circle, plug in, the coal electricity is shared, can save the energy and shorten the time that very hot oven is provided.

Therefore, the utlity model has electric ignition, igniting is fast, but not only can make coal stove but also can do electric furnace also the coal electricity shared, can satisfy the cooking heating to different firepower needs, burning fully, the characteristics of high, the environmental protection of the thermal efficiency.

(5) specific embodiment

Be described further below in conjunction with accompanying drawing, but be not limited only to this.

Shown in Fig. 1,2,3,4,5,6, the utility model coal electric furnace comprises furnace shell 2, stove circle 1, thermal insulation layer 3, ash drawing port 7, base 8, and is sleeved on together liner 4 and combustion chamber 5 in thermal insulation layer 3, seals 9 at the grate frame 6 of combustion chamber 5 and liner 4 lower ends, electric furnace 10 in grate frame 6 or grate frame, supports the end liner 11 of grate frame 6.Leave the gap between combustion chamber 5 and the liner 4, combustion chamber 5 has pore 12 from bottom to top; Grate frame 6 minutes is two-layer up and down, the periphery on upper strata have with combustion chamber 5 and liner 4 between the hole that is communicated with, gap; The stone or metal plate for standing a stove on as a precaution against fire of electric furnace 10 has passage 10a.When electric furnace 10 is in the grate frame, seal 9 without the grate frame, during without electric furnace 10, seal 9 with the grate frame and seal grate frame mouth.

Claims (2)

1, a kind of coal electric furnace, it comprises furnace shell (2), stove circle (1), thermal insulation layer (3), ash drawing port (7), base (8), it is characterized in that: it is sleeved on together liner (4) and combustion chamber (5) in addition in thermal insulation layer (3), grate frame (6) in combustion chamber (5) and liner (4) lower end, electric furnace (10) or grate frame in grate frame (6) seal (9), support the end liner (11) of grate frame (6), leave the gap between combustion chamber (5) and the liner (4), combustion chamber (5) has pore (12) from bottom to top, grate frame (6) divides two-layer up and down, the periphery on upper strata have with combustion chamber (5) and liner (4) between the hole that is communicated with, gap.

2, coal electric furnace according to claim 1 is characterized in that: the stone or metal plate for standing a stove on as a precaution against fire of electric furnace (10) has passage (10a).
