DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Example 1, as Figures 1 to 2As shown in the figure, a heating furnace includes a furnace core 1. On one side of the furnace core 1, a firewood feeding port 2 for adding firewood is connected and installed. At the bottom end of the furnace core 1, a metal furnace grate is installed. The top end of the furnace core 1 is in a fully open state. Outside the furnace core 1, a water tank 3 is provided. The water tank 3 is arranged in a surrounding manner around the furnace core 1, and the cross-sectional shape of the water tank 3 is set to be U-shaped. A welded and sealed cavity is formed between the furnace core 1 and the water tank 3, which is used to collect and discharge the waste smoke and exhaust gas generated by the combustion chamber to the outside through a metal smoke exhaust pipe 9. At the top of the furnace core 1, a tabletop 11 is provided, and a round hole is opened in the center of the tabletop 11. A cover plate 7 is fitted in the round hole.

[0021] In this embodiment, firewood is first added into the furnace core 1 through the firewood feeding port 2 for combustion. A sealed tabletop 11 is welded above the furnace core 1 and a round hole is opened in the middle. This round hole can be opened or closed by a movable cover plate 7. When needed, the cover plate 7 is opened to let the flames appear outside for cooking. When the flames are not needed to appear outside, the cover plate is closed to allow more heat energy to heat the water in the water tank 3 and provide warmth to the surroundings. On one side of the water tank 3, a water inlet and a water outlet are connected. Water is injected into the water tank through the water inlet, and the heated water can be discharged through the water outlet for use. By burning firewood and coal separately, the heat energy generated during the combustion process can be used for cooking or to raise the surrounding temperature for heating. At the same time, a surrounding water tank 3 is provided around the furnace core 1. After the water temperature in the water tank 3 rises, it can be used as domestic water and other hot water. The furnace body has rich functions, can meet a wider range of needs and uses, and shows higher flexibility and practicality.

[0022] Further, at the bottom of the metal furnace grate, a waste residue storage box 5 for collecting waste residues is provided. The waste residue storage box 5 passes through the water tank 3 and is in sliding fit with it. A first oxygen metal regulating valve 8 for adjusting the oxygen entering the combustion chamber is provided between the waste residue storage box 5 and the metal furnace grate. At one end of the metal smoke exhaust pipe 9 close to the combustion chamber, a second oxygen metal regulating valve 10 is provided.

[0023] In this embodiment, fuel is added through the firewood feeding port 2 and burned in the combustion chamber to generate heat energy. There is a cavity around the furnace core 1 to collect waste smoke and exhaust gas, which is discharged to the outside through the sealed tabletop 11. Outside the cavity is the welded and sealed furnace body. There is a metal furnace grate directly below the furnace core 1, and below the metal furnace grate is the waste residue storage box 5. This waste residue storage box 5 is designed in a drawer type, which is convenient for dumping the waste in the waste residue storage box 5. At the same time, a first oxygen metal regulating valve 8 for adjusting the oxygen intake is provided between the waste residue storage box 5 and the metal furnace grate. There is also a second oxygen metal regulating valve 10 at the initial stage of the tabletop 11. They work together to control the combustion speed and flame size of the combustion chamber.

[0024] Embodiment Two, as Figures 3 to 4As shown, a mounting base is installed at the bottom end of the water tank 3. A gas device box 4 is slidably connected inside the mounting base, and a natural gas combustion device 12 is arranged inside the gas device box 4.

[0025] In this embodiment, the gas device box 4 adopts a drawer-type design. At the same time, the natural gas combustion device 12 located inside the gas device box 4 can be used. The natural gas combustion device 12 can burn natural gas alone to heat the water in the water tank and warm the surrounding area. When burning natural gas alone, the heat energy generated during the combustion process can be used for cooking, and the surrounding temperature can be raised for heating. At the same time, the water tank 3 can be heated. After the water temperature in the water tank rises, it can be used for domestic living water and other hot water uses.

[0026] Furthermore, the gas device box 4 and the waste residue storage box 5 have the same size, and the gas device box 4 and the waste residue storage box 5 can be interchanged in position. After the gas device box 4 and the waste residue storage box 5 are interchanged in position and ignited, they can be used as an ignition source for the furnace core charcoal fuel.

[0027] Furthermore, the tabletop 11 is welded to the top of the water tank 3, and there is a gap between the top end of the furnace core 1 and the tabletop 11.

[0028] A gas device storage box 6 is slidably connected inside the water tank 3. The gas device storage box 6 is arranged at the gap position, and a large hole corresponding to the opening of the furnace core 1 in size is opened at the central part of the gas device storage box 6.

[0029] In this embodiment, the large hole opened at the central part of the gas device storage box 6 will not block the flame of the furnace core 1 from reaching the outside, thus affecting cooking. At the same time, the gas device storage box 6 has the same size as the gas device box 4 and the waste residue storage box 5. When the flame is needed at the position of the tabletop 11, the natural gas combustion device 12 can be placed inside the gas device storage box 6 for combustion and heating for cooking. There is also a surrounding of the water tank 3 under the tabletop 11. After the water in the water tank 3 is heated, the entire tabletop 11 and the surrounding of the furnace body will also become warm with the temperature rising.

[0030] Furthermore, a heat insulation net is distributed around the outside of the water tank 3 to prevent the people warming themselves from touching the high-temperature furnace body and getting scalded.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
