Abstract

The utility model relates to a coal stove for hot air heating, which comprises a stove body which is composed of an outer housing, a stove plate, an internal furnace, a heat insulation layer, a fire sealing opening and a base. The outer ring of the heat insulation layer is sheathed with a star-shaped or tubular heatradiator of the internal furnace; one side of the stove plate is provided with a flue heat radiator. When cold air goes into the stove body, the utility model can carry out sufficient heat exchange through an air duct which is arranged in stove, the flue heat radiator and the heat radiator of the internal furnace; so the cold air become hot air and can be drained into rooms through the outlet of the air duct.

Description

The coal hot-air warming stove

The utility model relates to a kind of coal hot-air warming stove.

At present, for general family cook, the warm oneself coal stove of usefulness, what generally adopt is body of heater smoke pipe radiating mode, its shortcoming is that area of dissipation is little, it is slow to heat up, and temperature is low, and the temperature instability in the burner hearth, it is also insufficient to burn, though there are some burning hot blast warming stoves to appear on the market in recent years, in entering the body of heater heating chamber, air easily produces bias current, and the heat that causes burner hearth to distribute can not fully be absorption of air, thereby cause the waste of heat, influence heating effect.

The purpose of this utility model provides a kind of coal hot-air warming stove.It is to adopt direct heat transfer mode by force, and this mode can guarantee that fire box temperature is stable, makes full combustion of fuel, and the heat that stove produces can be absorbed to form hot blast by air as far as possible.

The purpose of this utility model is achieved in that it comprises by shell, stone or metal plate for standing a stove on as a precaution against fire, flue, heat-insulation layer and banks up a fire mouthful and body of heater that base is formed, and its primary structure is characterised in that,

In the outer ring of described heat-insulation layer, be with the flue radiator 8 of ¤ shape, tubular, between the shell of flue radiator and body of heater, be provided with air channel 9, this air channel 9 connects with the annular passage and the ducting outlet that are located in the base of furnace body,

The lower end of described stone or metal plate for standing a stove on as a precaution against fire also is provided with annular passage 10, is provided with wind inlet channel 11 in a side of stone or metal plate for standing a stove on as a precaution against fire, and above-mentioned air channel 9,10,11 is UNICOM successively in the joint,

Flue radiator 12 also is housed in wind inlet channel 11, and wherein the smoke intaking hole of flue radiator joins with the flue outlet that is located on the stone or metal plate for standing a stove on as a precaution against fire, and the exhaust smoke hole on the flue radiator and the external world are conducted,

Air-blast device also is equipped with at the air inlet place of above-mentioned wind inlet channel 11.

Good effect of the present utility model is, after cold air enters body of heater, through the pressurization of air blast, in body of heater, carry out sufficient heat exchange around flue radiator and flue radiator, become hot-air, enter indoor again by ducting outlet, be characterized under the situation that consumes equal fuel quick heating, heat energy utilization rate height, and the indoor no bias current phenomenon generation of being heated, hot blast air quantity, wind-warm syndrome are stablized.

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

Fig. 1 is a cutaway view of the present utility model,

Fig. 2 is an A-A cutaway view of the present utility model,

Fig. 3 is a flue radiator structural representation of the present utility model,

Fig. 4 is the sectional view of Fig. 3,

Fig. 5 is the side view of body of heater in the utility model.

As shown in Figure 1 and Figure 2, the utility model comprises the body of heater of being made up of shell 1, stone or metal plate for standing a stove on as a precaution against fire 2, flue 3, heat-insulation layer 4, base 5 and the mouth of banking up a fire, and the mouth of wherein banking up a fire comprises the bank up a fire mouth 6 and mouthful 7 (see figure 5)s of banking up a fire, and is located at the bottom and a side of body of heater lower end respectively, its contribution to prior art is

It also includes a flue radiator 8 that is ¤ shape, tubular, and this flue radiator muff-joint is provided with air channel 9 in the outer ring of heat-insulation layer between the shell of flue radiator and body of heater, and this air channel connects with the annular passage and the ducting outlet 14 that are located in the base of furnace body,

The lower end of above-mentioned stone or metal plate for standing a stove on as a precaution against fire also is provided with annular passage 10, relies on a side of its flue outlet at stone or metal plate for standing a stove on as a precaution against fire, is provided with wind inlet channel 11, and above-mentioned air channel 9,10,11 is UNICOM successively in the joint,

Flue radiator 12 also is housed in wind inlet channel 11, the heat abstractor that its shape and structure can be used with reference to other purpose of the work of seeing on the market, what choose in the utility model is one to have the cavity of smoke intaking hole and exhaust smoke hole, have dividing plate in the cavity, cavity is equipped with fin outward (sees Fig. 3, Fig. 4), with cigarette that increases heat or the time that gas stops within it as far as possible, make it fully carry out the heat exchange (see figure 2), the smoke intaking hole of above-mentioned flue radiator joins with the flue outlet that is located on the stone or metal plate for standing a stove on as a precaution against fire, and the exhaust smoke hole on the flue radiator and the external world are conducted, in order to quicken the hot-air exchange, air-blast device also is equipped with at the air inlet place of above-mentioned wind inlet channel.

Its course of work is as follows,

As shown in Figure 1; Cold air enters body of heater by the air inlet 16 (seeing Fig. 5) of wind inlet channel; By air-blast device 13 flue radiator 12 places are upwards delivered in its pressurization; Cold air is through the fin shunting of flue radiator; Carry out equably heat exchange; Fin imports annular passage 10 under the stone or metal plate for standing a stove on as a precaution against fire 2 with air-flow; Again carry out heat exchange along flue radiator 8 and the formed air channel 9 of body of heater shell again; Heated air enters indoor from ducting outlet 14 constantly; Can make at short notice room temperature rising 5-10 degree

The utility model is respectively equipped with the

mouth

6 and 7 of banking up a fire in a side and the bottom of body of heater lower end, its purpose is, increase the oxygen supply amount in the burner hearth, the waste gas and the part heat of burning enter flue radiator by the flue outlet that is located on the stone or metal plate for standing a stove on as a precaution against fire, after the outer cold air of fin on the process flue radiator 12 and flue radiator carries out heat exchange, pass through flue radiator exhaust smoke hole 15 again, or enter chimney, or otherwise discharge outdoor.
