[0042] For a better understanding of the content of the present disclosure, further description will be made below with reference to specific embodiments and the accompanying drawings. It should be understood that these embodiments are provided for further illustration of the present disclosure only and are not intended to limit the scope of the present disclosure. Further, it should be understood that after reading the content of the present disclosure, those skilled in the art may make some non-essential changes or adjustments to the present disclosure, which still fall within the scope of protection of the present disclosure.

Embodiment 1

[0043] As shown in FIGS. 1 to 8, a fireplace for gasifying and burning fuel according to this embodiment includes a housing 1, a burner 2, a gasification device 3, a liquid supply device 4, a fuel tank 5, a controller 6, and a decorative piece 7. In this embodiment, the burner 2 is provided above the housing 1. The burner 2 is composed of a gas intake port 21, six horizontal portions 22, and three inclined portions 23. The inclined portions 23 are inclined upwardly at an angle < with respect to the horizontal portions 22. In this embodiment, upwardly inclined angles < of the three inclined portions 3 are different from each other, and are 46, 55, and 62, respectively. In this embodiment, an upper surface of each horizontal portion 22 is horizontal, and a lower surface of the horizontal portion 22 has an upwardly inclined angle <. In this embodiment, < is 3 for all the horizontal portions 22. A lower end of each inclined portion 23 is connected and fixed to one end of a horizontal portion 22, and the other ends of all six horizontal portions 22 are connected to the combustion chamber main body 24 so that the other ends of the horizontal portions 22 are connected to each other, and the horizontal portions 22 are arranged around the circumference of the combustion chamber main body 24. In this embodiment, the spacing between any two of the horizontal portions 22 is the same, and the combustion chamber main body 24, the horizontal portions 22, and the inclined portions 23 each have an internally hollow structure and communicate with each other. The horizontal portions 22 are provided with a plurality of first flame holes 221, the inclined portions 23 are provided with a plurality of second flame holes 231, and the combustion chamber main body 24 is provided with a plurality of third flame holes 241. The gas intake port 21 is provided below the combustion chamber main body 24. The gas intake port 21 is connected to an outlet of the gasification device 3 through a gas inlet pipe 8 made of non-metal. The combustion chamber main body 24 is further provided with three combustion air inlets 242 through which combustion air can be supplemented for a middle region of the burner 2, and upper surfaces of the combustion air inlets 242 are higher than an upper surface of the combustion chamber main body 24. The gasification device 3 includes a gasification chamber 31 and heating elements 32, an inner cavity of the gasification chamber 31 is provided with cooling fins 33, and the heating elements 32 are provided below the inner cavity of the gasification chamber 31. The gasification device 3, the liquid supply device 4, and the controller 6 are all arranged inside the housing 1, and the fuel tank 5 is arranged outside the housing 1. An output port of the fuel tank 5 is connected to an inlet of the liquid supply device 4, and an outlet of the liquid supply device 4 is connected to an inlet of the gasification device 3. The controller 6 is matched and connected to the gasification device 3, the heating elements 32, and the liquid supply device 4. In this embodiment, the liquid supply means 4 is a constant delivery pump. The decorative piece 7 is provided at the periphery of the housing 1, the burner 2, and the fuel tank 5. The housing 1, internal components thereof, and the fuel tank 5 are hidden inside the decorative piece 7. The burner 2 is provided at a middle position of the decorative piece 7. The bottom of the burner 2 is provided and covered with pebbles 9, used to simulate the structure of a carbon bed after a real solid fuel is burned. The pebbles 9 may cover the combustion chamber main body 4 and/or the horizontal portions 2, so that it looks more beautiful and realistic as a whole, and only the burner 2, the pebbles 9, and the decorative piece 7 can be seen in the whole appearance. In this embodiment, three simulated solid fuels 5 are further included. Supporting surfaces 232 are provided on the inclined portions 23, and the simulated solid fuels 25 are fastened to the inclined portions 23, and supported and positioned by the supporting surfaces 232. Moreover, the simulated solid fuels 25 have textures and colors simulating real firewood.

[0044] In addition, in this embodiment, an ignition device 10 and a flame detecting device 20 are further included. The ignition device 10 is arranged close to the first flame holes 221, and the flame detecting device 20 is also arranged close to the first flame holes.

[0045] The operation process of the fireplace for gasifying and burning fuel according to this embodiment is as follows: [0046] during the operation of this embodiment, the controller 6 controls the liquid supply device 4 to draw the liquid fuel from the fuel tank 5 into the gasification device 3. The controller 6 controls the heating elements 32 to heat, so that the liquid fuel is gasified in the inner cavity of the gasification chamber 31. Then, the gasified fuel enters the interior of the burner 2 through the gas intake pipe 8, is diffused into the combustion chamber main body 24 and/or the interior of the horizontal portions 22 and the inclined portions 23, and further emitted from the third flame holes 241, the first flame holes 22 and the third flame holes 231. At this time, the controller 6 controls the ignition device 10 to ignite the gaseous fuel, and then flames are burning in each of the combustion chamber main body 24 and/or the horizontal portions 22 and the inclined portions 23, thereby forming a flame effect in a three-dimensional (3D) form. The flame detecting device 20 may detect the flame state of the burner 2 to ensure stable flame combustion. Moreover, the combustion air inlets 242 may be used to supplement the middle region of the burner with air required for combustion, so that the combustion is more complete and the flames are brighter.

[0047] In addition, the simulated solid fuels 25 are provided on the inclined portions 23, and the bottom of the burner 2 is provided with the pebbles 9 to cover the combustion chamber main body 24 and the horizontal portions 22, so that a user can see only the pebbles 9 and the simulated solid fuels 25 at the time of viewing for enjoyment, which is more harmonized and unified as a whole, making the flames more realistic like real firewood burning in a bonfire, which is warm and comfortable.

Embodiment 2

[0048] As shown in FIGS. 9 to 13, this embodiment is different from Embodiment 1 described above in that the housing 1 is a cavity body having an internal furnace cavity 11, the burner 2 is provided in the internal furnace cavity 11 of the housing 1, the burner 2 of this embodiment has no combustion chamber main body, and only two horizontal portions 2 are arranged opposite to each other; and the two horizontal portions 2 are connected to each other to form one body, and the gas intake port 1 is provided below the horizontal portions 2. In this embodiment, the fuel tank 5 is also provided inside the housing 1 and below the burner 2.

[0049] A furnace door 13 with a flame observation opening 12 is further provided in front of the housing 1, so that the burner 2 and the flames burning thereon can be observed through the flame observation opening 12. A smoke exhaust device 14 is further provided at the back of the housing 1, and exhaust gas such as carbon dioxide generated by combustion can be exhausted to the outside through the smoke exhaust device 14.

[0050] The flame observation opening 12 may be directly hollow, and the furnace cavity 11 is in direct communication with the outside of the furnace door 13, so that heat diffusion is better performed. The flame observation opening 12 may also be provided with transparent glass, so that the carbon dioxide generated by the combustion does not diffuse through the flame observation opening 12 to the space where the use environment is located, and the heat generated by the combustion is not blocked too much.

[0051] The above description does not limit the present disclosure, and the present disclosure is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the essence of the present disclosure shall also fall within the protection scope of the present disclosure.
