Fig. 2 is a schematic left view of the utility model.

The utility model is described in further detail in conjunction with accompanying drawing and embodiment now.

As shown in the figure, the utility model includes a furnace body and a furnace tile 4, a grate 2 is installed at the bottom of the furnace tile 4, and an ash bucket 1 is arranged directly below the furnace grate 2, which is composed of the grate 2 and the ash bucket 1 The dust cleaning device is also the first air inlet channel. The furnace body is composed of an inner cylinder 15, an outer cylinder 18, a fire-holding cylinder 14, an inclined fire pipe 8, and a fire-holding plate 19. The inner cylinder 15 and the fire-holding cylinder 14 are fixedly connected, and the air barrier between them and the outer cylinder 18 is a heating water container. 20. One end of the inclined fire tube 8 is fixedly connected to the fire holding tube 14, and the other end is fixedly connected to the fire holding plate 19. The inclined fire pipe 8 can be one or more, and is evenly distributed in the heating water container 20. The heating water container 20 The upper and lower parts respectively have a heating water outlet 7 and a heating water inlet 17. A secondary air inlet pipe 3 is fixedly installed between the furnace tile 4 and the inner cylinder 15, and one end of the secondary air inlet pipe 3 leads to the fire suffocating tube 14 on the top of the furnace tile 4, and the other end protrudes from the bottom of the furnace tile 4 to communicate with the outside world. In the same way, the air directly enters the fire-holding tube on the upper part of the furnace tile to meet the hot carbon monoxide and intensify the combustion. The heating water container 20 is surrounded by a sanitary hot water heating pipe 5, one end of the sanitary hot water heating pipe 5 extends out of the outer cylinder 18 as the sanitary hot water inlet 6, and the water to be heated enters therefrom, and the other end also extends out of the outer cylinder 18 as the sanitary hot water inlet 6. Sanitary hot water outlet 13, from which hot water is discharged. A return water suspension box 16 is fixedly connected to the outer cylinder 18 at the lower part of the inner cylinder 15. The return water suspension box 16 is provided with a heating water inlet 17 communicating with the lower part and extending out of the outer cylinder 18 and a heating water inlet 17 communicating with the upper part and extending out of the outer cylinder 18. The water outlet 7 is connected with the indoor heating water pipe, and the purpose of heating and sanitary hot water supply is achieved through the reciprocating circulation of hot water in the water pipe. An inner fire cover 9 is arranged on the top of the fire tube 14, and an outer fire cover 10 is provided on the top of the outer tube 18. A chimney seat 12 is fixedly installed on the upper side of the outer tube 18, and a windshield is arranged in the chimney seat 12. The plate 11 controls the degree of opening and closing of the windshield 11 as required.

The fire holding device is composed of a fire holding tube 14, an inner holding fire cover 9, an outer holding fire cover 10, and an inclined fire pipe 8. The heating water container 20 is composed of an inner cylinder 15, an outer cylinder 18, a holding fire tube 14, and a fire holding plate 19. The sanitary hot water device is constituted by a sanitary hot water heating pipe 5 built in a heating water container 20 .

The above-mentioned inclined water pipe 8 is oblique relative to the radial or axial direction of the fire holding tube 14 .

The above-mentioned sanitary hot water device is arranged in the heating water container 20, and its water heating method is a flowing water type rather than a volumetric type.

Above-mentioned suffocating fire tube 14 is trumpet type or inverted T-shaped structure.

When in use, the fuel burns in the furnace tile 4, and the heat transferred radially from the upper half of the furnace tile 4 heats the heating water in the heating water container 20. When the fire is suppressed, the high-temperature furnace gas is forced to exchange heat through the inclined fire tube 8 to heat the heating water again, and flows into the upper space to be discharged through the flue. When cooking with an open fire, you only need to open the inner and outer lids 9 and 10 to place the pot on it. At this time, because the upper flow resistance of the high-temperature furnace gas is reduced, the burning speed is accelerated, and the high-temperature furnace gas directly scours the bottom of the pot upwards. To achieve the purpose of cooking. With the acceleration of the burning speed, the resistance of the high-temperature furnace gas to scour the bottom of the pot increases, and a part of the high-temperature furnace gas still flows out through the inclined fire tube 8 to heat the heating water and sanitary hot water, which not only achieves the purpose of heating and cooking, but also can be used at any time. Sanitary hot water is provided. When using sanitary hot water, the running water enters the sanitary hot water heating pipe 5 from the sanitary hot water inlet 6 and then flows out through the sanitary hot water outlet 13. By heating and adjusting the flow rate of the sanitary hot water, the temperature of the discharged hot water can be controlled to achieve the washing effect. Purpose. The three functions of heating, cooking and providing sanitary hot water can be realized simultaneously or separately.
