[0002] In rural, outdoor, and remote areas, wood-burning stoves have long been widely used as the primary cooking and heating tools. However, existing traditional stoves employ an open combustion structure, resulting in incomplete fuel combustion (thermal efficiency less than 20%), requiring frequent refueling and consuming large quantities of fuel. Simultaneously, unburned smoke (containing harmful substances such as CO and PM2.5) is directly emitted into indoor spaces or the environment, endangering health and causing air pollution. Furthermore, existing stoves only have single functions such as cooking, failing to meet people's growing needs, and require manual adjustment of airflow and ash removal, while also posing safety hazards such as flame splashing and backdraft.
[0003] Therefore, a new type of stove structure is needed to solve the above problems. Summary of the Invention

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] Please see Figure 1 The multifunctional smokeless wood gasification furnace shown in a preferred embodiment of this application includes a base 9 and a furnace body 12 disposed on the base 9. An oxygen inlet switch 11 and an ash collection box 10 are disposed below the furnace body 12. A wood-adding port 15 is disposed on the side wall of the furnace body 12, and a furnace door is disposed on the wood-adding port 15.
[0021] Specifically, the furnace body 12 includes an internal gasification chamber 14, a cast iron furnace liner 13, and an oven 7;
[0022] More specifically, a heating tube is installed inside the furnace body 12, and an air inlet pipe 6 and an air outlet 8 are provided on the furnace body 12. The two ends of the heating tube are connected to the air inlet pipe 6 and the air outlet 8, respectively.
[0023] Furthermore, a water tank 16 is provided above the furnace body 12, and a removable water tank cover 17 is provided on the water tank 16. The water tank 16 is connected to an external water source pipeline through a float control valve 18, and has the functions of automatic water storage and automatic shutdown when the water is full.
[0024] Preferably, the water tank 16 has a volume of 40-60L, which can meet the needs of family bathing and domestic water use. The water tank 16 is equipped with a faucet 19 and other drainage devices. It can also be connected to an external water pump to pump water into insulated containers such as insulated buckets or water heater storage tanks, or it can be pumped directly to the bathroom and connected to a mixing valve and shower head for bathing.
[0025] The furnace body 12 is also equipped with a flue 5, which extends out of the furnace body 12 and has an exhaust pipe 1 at the end. The end of the exhaust pipe 1 is connected to the chimney or directly passes through the roof to the outside.

[0027] Working principle:
[0028] Open the furnace door, add firewood to the furnace chamber through the firewood inlet and ignite it. Then close the furnace door, open the water valve of the water tank to fill water, and when the combustion inside the furnace chamber reaches a certain temperature, close the oxygen inlet switch to force the smoke into the gasification chamber, forming a gasification effect. This allows most of the smoke particles and toxic gases to be fully combusted before being discharged outdoors through the chimney.
[0029] During this process, the high temperature generated inside the furnace is transferred to the furnace body to heat the water tank and oven. At the same time, a small blower can be installed in the air inlet pipe to heat the cold air and discharge it through the exhaust port, which can be used as a warm air conditioner. The water tank cover can also be used as a tabletop.
[0030] In summary, the stove shown in this application has a simple structure, diverse functions, is easy to use, and is energy-saving and environmentally friendly, giving it a significant advantage over existing technologies.
