Description

high efficiency dual-purpose stove

The utility model relates to a kind of domestic cooking, the dual-purpose stove and accessory of heating.

Along with improving constantly of living standards of the people, people also improve day by day to the requirement of living environment, not only require indoor air temperature to get well, and require indoor environment cleaning, health, therefore, the family life environment of traditional civil stove and accessory of cooking in indoor direct heating incompatibility today because it pollutes room, heating effect difference.So, the existing trend that progressively replaces traditional coal stove of a large amount of civilian native heating installation.

The producer that produces stove implements at present is a lot, and the structure of stove implements is also various, but because of structural problem can not reduce heat loss effectively, heating effect is not satisfactory, and some Range structure is comparatively complicated, and trouble is installed, and is difficult for promoting.

The purpose of this utility model provides a kind of high-efficiency dual-purpose stove and accessory that is used for cooking and heating, and it can improve the thermal efficiency of stove and accessory effectively, and fuel savings is eliminated flue dust, and had good heat insulation effect.

The purpose of this utility model is achieved in that it is made of body of heater, burner hearth, stove seat, tile, flue etc., flue is annular flue, one exhaust opening is arranged on the flue, between burner hearth and annular flue, ring-shaped water jacket is housed, there is a delivery port water jacket upper end, the lower end is a water return outlet, and at least one heat pipe is housed in the body of heater, and the heat pipe upper end feeds ring-shaped water jacket.

That the utility model has adopted is unique, heat pipe heat exchanging technology efficiently, it is loaded on heat pipe in the body of heater, the lower end of heat pipe is in the high-temperature region around the burner hearth, insert in the water jacket upper end, because heat pipe is the minimum heat transfer element of a kind of thermal resistance, its heat transfer efficiency and heat transfer rate are high, and can transmit a large amount of thermic loads under the minimum situation of the temperature difference, therefore the heat pipe that is installed in the body of heater of a large amount of waste heats of burner hearth absorbs, and conducts in water jacket.At this moment, the ring-shaped water jacket that is installed between burner hearth and the annular flue is subjected to the thermal source heating of three places, one place is the direct heating of fire door firepower, second place is the heating of the waste heat of annular flue to water jacket, the 3rd place is that heat pipe absorption burner hearth waste heat conducts the heat in water jacket, and this three places thermal source is rapidly heated the cold water in the water jacket, boosts, be connected with radiator by delivery port, realize circulation heating.After banking up a fire night, because the temperature in the burner hearth is also more than 100 ℃, by heat pipe for thermal conductivity, room temperature descends few.

Because heat pipe design uniqueness of the present utility model can be got nearly all heat energy and heat loss back, and be output as practical heat energy efficiently, improve indoor temperature and heating area, so performance is higher than like product; Fume extractor is designed to annular flue, has reduced exhaust gas temperature, helps the waste heat recovery in the flue, has dust removing effects simultaneously, indoor no coal gas.

The utility model has the advantages that: compact conformation, thermal efficiency height, coal consumption is lower than like product, and smoke abatement and dust control is safe and reliable, long service life, installation, maintenance is all very convenient.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the heat pipe schematic diagram among the utility model embodiment 1.

Fig. 3 is the heat pipe schematic diagram among the utility model embodiment 2.

Among the figure, 1. body of heater 2. heat pipes 3. exhaust openings 4. delivery ports 5. water jackets 6. flues 7. water return outlets 8. tiles 9. burner hearths 10. stove seats

High-efficiency dual-purpose stove provided by the utility model, the outer wall of body of heater (1) is equipped with insulation material, tile (8) is housed around the burner hearth (9), flue (6) is annular flue, on the annular flue exhaust opening (3) is arranged, between burner hearth (9) and annular flue (6) ring-shaped water jacket (5) is housed, it is water return outlet (7) that there are a delivery port (4), lower end in water jacket (5) upper end.In embodiment 1, uniform three heat pipes (2) between body of heater (1) outer wall and the tile (8), the upper end of heat pipe feeds ring-shaped water jacket (5), and heat pipe (2) and the weldering of ring-shaped water jacket (5) junction are dead.

This stove and accessory fire door can be cooked, and water jacket (5) is discharged hot water for heating by delivery port (4), and cold water enters water jacket from the water return outlet (7) of water jacket, and at this moment water jacket (5) is subjected to the firepower heating of three places: the firepower of fire door is the heating water jacket directly; The waste heat of the annular flue (6) of water jacket periphery also about 160 ℃, can directly heat water jacket; The waste heat that burner hearth (9) laterally distributes utilizes heat pipe (2) that waste heat is almost all reclaimed about 400 ℃, conducts in ring-shaped water jacket.Therefore, the cold water in the ring-shaped water jacket can heat up rapidly, boosts, and is transported to radiator by delivery port (4), reaches circulation heating purpose.

Adopt the heat pipe heat exchanging technology to also help indoor heat insulating after banking up a fire, because of the rear hearth waste heat of banking up a fire also more than 100 ℃, make the water in the water jacket keep uniform temperature by heat pipe for thermal conductivity, so room temperature descends seldom.

The heat pipe of embodiment 2 (2) adopts annular tube type heat pipe (as shown in Figure 3), and its installation site is identical with embodiment 1.The annular tube type heat pipe has increased the heat pipe for thermal conductivity area, has further improved the thermal efficiency.

After tested, the utility model thermal efficiency is up to 80%-85%, quick heating, and the consumption coal is low, and fire-sealing time is long, is cooking, heating equipment desirable in the family.

Claims (2)

1, a kind of high-efficiency dual-purpose stove, by body of heater (1), burner hearth (9), stove seat (10), tile (8), flue formations such as (6), it is characterized in that: flue (6) is annular flue, one exhaust opening (2) is arranged on the flue (6), between burner hearth (9) and annular flue (6) ring-shaped water jacket (5) is housed, it is water return outlet (7) that there are a delivery port (4), lower end in the water jacket upper end, at least one heat pipe (2) is housed in the body of heater (1), and the heat pipe upper end feeds ring-shaped water jacket (5).
