[0002] A stove is a device that burns coal or other biomass fuels for heating or cooking. It mainly includes a stove barrel for insulation and a combustion chamber inside the stove. Coal or biomass fuel is placed in the combustion chamber and burns to generate heat, which is then dissipated by the stove body to achieve the purpose of heating.

[0003] For example, the patent with publication number CN107289466A discloses a stove with an induced draft device, including a base, a furnace body on the base, a fireproof cover on the furnace body, a panel on the fireproof cover, a furnace chamber in the furnace body, a furnace bridge in the furnace chamber, an ash hopper under the furnace bridge, a feed port passing through the furnace body and connected with the furnace chamber, an oven is provided on the side opposite to the furnace body and the feed port, a smoke exhaust channel is provided at the bottom of the oven, the smoke exhaust channel is provided with an outer smoke exhaust port and a lower smoke exhaust port, which can adapt to two chimney installation methods: overhead and underground. In the channel for smoke circulation, an induced draft device is provided, which is composed of fan blades and a drive shaft. The induced draft device is provided in the induced draft chamber or the base, and can also constitute a ground flue stove with an induced draft device in which the smoke pipe is installed close to the ground.

[0004] The problem with the above-mentioned existing technology is that when the stove is used, the ash hopper needs to be opened to let in air, the feed port needs to be opened to put the fuel on the stove bridge, and the fuel needs to be ignited. In actual use, the carbon ash formed after the fuel is burned will fall into the ash hopper. When the opening of the ash hopper is too large, the carbon ash in the ash hopper will easily drift into the room, thereby polluting the room. If the opening of the ash hopper is too small, the air intake will be reduced, resulting in incomplete combustion of the fuel, which is easy to produce carbon monoxide and waste resources.

[0005] For this reason, a multifunctional stove is proposed to solve the above-mentioned technical problems. Utility Model Content

[0008] As a further improvement of the above technical solution, at least one cooking port is provided on the top of the main body, and the cooking port is connected to the smoke exhaust assembly.

[0009] As a further improvement of the above technical solution, the smoke exhaust component includes a first smoke exhaust channel arranged at the top of the furnace and a second smoke exhaust channel arranged on the side of the furnace, and the first smoke exhaust channel is connected to the second smoke exhaust channel; the smoke exhaust component also includes an upper smoke exhaust pipe connected to the outside world or a lower smoke exhaust pipe connected to the outside world, and the second smoke exhaust channel is connected to the upper smoke exhaust pipe or the lower smoke exhaust pipe.

[0010] As a further improvement of the above technical solution, it also includes a fan, which is arranged on the outside of the main body and is connected to the lower smoke exhaust duct.

[0011] As a further improvement of the above technical solution, an oven is provided in the main body, and the oven is located in the second smoke exhaust channel.

[0012] As a further improvement of the above technical solution, a partition is provided between the second smoke exhaust channel and the upper smoke exhaust pipe.

[0013] As a further improvement of the above technical solution, a visual window is hinged at the feeding port.

[0014] As a further improvement of the above technical solution, a panel is provided on the top of the cooking opening.

[0015] The beneficial effects of the present invention are as follows: fuel enters from the charging port and is placed on the furnace bridge, the fuel is ignited, air can enter from the air inlet and enter the furnace from the air inlet channel, sufficient air is provided for the fuel, the carbon ash formed after the fuel is burned can fall into the ash hopper, and the generated smoke can be discharged to the outside through the smoke exhaust component.
