[0002] Wind-heated fireplaces are independent or wall-built indoor heating devices that use combustibles as energy. They have chimneys inside and originated from heating facilities in Western homes or palaces. Existing fireplaces generally include exhaust pipes and combustion chambers.

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] Example: Reference Figure 1-2A wind-heated cooking fireplace comprises a furnace body 1, in which a fuel delivery mechanism 2, a heat exchange mechanism 3 and a combustion chamber 4 are installed. The combustion chamber 4 is located at one side of the furnace body 1, and the fuel delivery mechanism 2 is located at the other side of the furnace body 1. The heat exchange mechanism 3 is located between the combustion chamber 4 and the fuel delivery mechanism 2; the combustion chamber 4 comprises a combustion box 5, the output end of the fuel delivery mechanism 2 is connected to the upper part of the combustion box 5, and the lower part of the combustion box 5 is connected to an oxygen delivery pipe 6. A sieve plate is installed in the combustion box 5, and the sieve holes on the sieve plate can be used for ventilation. While keeping oxygen entering the combustion chamber 4 smoothly, large particles of fuel waste can be prevented from entering the oxygen delivery pipe 6, thereby reducing the pollution of the fuel to the oxygen delivery pipe 6. The fuel delivery mechanism 2 comprises a silo 10 and a feeding assembly. The silo 10 is installed at one side of the furnace body 1, and the outlet of the silo 10 is connected to the feeding assembly. The feeding assembly includes a first feeding motor 11 and a second feeding motor 12. The first feeding motor 11 is located above the second feeding motor 12. The outlet of the silo 10 is connected to a first feeding pipe 15. The first feeding pipe 15 is connected to the second feeding pipe 16. The second feeding pipe 16 is connected to the third feeding pipe 17. The third feeding pipe 17 is connected to the combustion chamber 4. A first feeding auger 13 is installed in the first feeding pipe 15. The output end of the first feeding motor 11 is connected to the first feeding auger 13. A second feeding auger 14 is installed in the third feeding pipe 17. The output end of the second feeding motor 12 is connected to the second feeding auger 14. The fuel is poured into the silo 10 and flows into the first delivery pipe 15 from the outlet of the silo 10. The first feeding motor 11 is started, driving the first feeding auger 13 to rotate, thereby driving the fuel in the first delivery pipe 15 to flow into the second delivery pipe 16 and the third delivery pipe 17 in sequence. At the same time, the second feeding motor 12 is started, driving the second feeding auger 14 to rotate, thereby driving the fuel in the third delivery pipe 17 to flow into the combustion box 5. Oxygen is transported into the combustion box 5 from the oxygen delivery pipe 6, making the fuel combustible. The method of feeding by the first feeding auger 13 and the second feeding auger 14 can avoid the problem of spontaneous combustion caused by the backflow of outdoor air into the furnace body 1. A water boiling and cooking port 7 is provided at the top of the furnace body 1, which is located just above the combustion chamber 4. A heat conducting plate 8 is placed on the top of the water boiling and cooking port 7. The heat conducting plate 8 is made of microcrystalline glass. A pipe 9 is connected to the furnace body 1 above the water boiling and cooking port 7. The pipe 9 can concentrate the flame on the pipe 9. The flame can transfer heat to the heat conducting plate 8 through the pipe 9, so that the pot and kettle placed on the heat conducting plate 8 can be heated to achieve the effect of cooking and boiling water. At the same time, the heat energy generated by the combustibles can be fully utilized to improve the thermal efficiency.

[0019] The heat exchange mechanism 3 includes a heat exchange chamber 18, a heat exchange tube 19 and an inertial flow fan 20. The inertial flow fan 20 is connected to the heat exchange chamber 18. The heat exchange chamber 18 is located in the furnace body 1 and between the combustion chamber 4 and the fuel delivery mechanism 2.

The heat exchange mechanism 3 also includes a smoke exhaust mechanism, which includes a smoke exhaust fan 21. The smoke exhaust fan 21 is connected to the combustion chamber 4. After the fuel is burned, the high-temperature smoke generated flows from the upper part of the combustion chamber 4 into the heat exchange tube 19, then flows into the lower part of the combustion chamber 4 through the heat exchange tube 19, and then is discharged through the smoke exhaust fan 21. At the same time, the airflow flowing into the room flows into the upper part of the heat exchange chamber 18, passes through the outer surface of the heat exchange tube 19 for heat exchange, and is discharged through the inertial flow fan 20, thereby increasing the temperature of the indoor air.

[0020] The working principle of the utility model is as follows: the fuel is poured into the silo 10, and flows into the first feeding pipe 15 from the outlet of the silo 10. The first feeding motor 11 is started, driving the first feeding auger 13 to rotate, thereby driving the fuel in the first feeding pipe 15 to flow into the second feeding pipe 16 and the third feeding pipe 17 in sequence. At the same time, the second feeding motor 12 is started, driving the second feeding auger 14 to rotate, thereby driving the fuel in the third feeding pipe 17 to flow into the combustion box 5. Oxygen is transported into the combustion box 5 from the oxygen delivery pipe 6, so that the fuel can be combusted. The flame generated by the fuel is concentrated below the heat transfer plate 8 through the pipe 9, and its heat is transferred to the heat transfer plate 8, so that cooking and boiling water can be carried out. After the fuel is burned, the high-temperature smoke generated flows from the upper part of the combustion chamber 4 into the heat exchange tube 19, and then flows into the lower part of the combustion chamber 4 through the heat exchange tube 19, and then is discharged through the smoke exhaust fan 21. At the same time, the airflow flowing into the room flows into the upper part of the heat exchange cavity 18, passes through the surface of the heat exchange tube 19 for heat exchange, and is discharged through the inertial flow fan 20, thereby increasing the temperature of the indoor air, and it works in this way.
