Examples

Referring to fig. 1 and 2, the present embodiment provides a hot air heating furnace, which includes a furnace body 1, a combustion chamber 2 is disposed inside the furnace body 1, a furnace chamber 3 and an ash collecting chamber 4 are sequentially disposed below the combustion chamber 2, in order to add fuel into the furnace chamber 3 and clean ash generated after fuel is combusted in the ash collecting chamber 4, a feed port 5 and an ash removing port 6 are disposed on the furnace body 1, the feed port 5 is communicated with the furnace chamber 3, and the ash removing port 6 is communicated with the ash collecting chamber 4. Preferably, the feeding port 5 of the present embodiment is obliquely arranged so that fuel can enter the hearth 3 quickly, the bottom of the hearth 3 is provided with a grate, the ash collecting chamber 4 and the ash removing port 6 are ash collecting drawers which can be pushed and pulled, and when ash falls into the ash collecting drawers and is accumulated to a certain extent, the ash collecting drawers can be directly pulled out to clean the ash in the ash collecting drawers.

Meanwhile, in order to improve the combustion effect of the fuel, a combustor 7 is arranged at the top of the hearth 3, and the combustion chamber 2 is communicated with the hearth 3 through the combustor 7. In order to facilitate the discharge of the flue gas generated in the combustion chamber 2, the furnace body 1 is provided with a smoke exhaust pipe 8, the side wall of the combustion chamber 2 is provided with a smoke exhaust port, and the smoke exhaust pipe 8 is communicated with the combustion chamber 2 through the smoke exhaust port.

Considering that the existing heating furnace usually uses water as a heating medium, the heating process is slow and the heating effect is poor. For this reason, the periphery of the combustion chamber 2 of this embodiment is provided with a heating chamber 9, the heating chamber 9 is arranged around the combustion chamber 2, and the furnace body 1 is provided with an air inlet pipe 10 and an air outlet pipe 11 which are communicated with the heating chamber 9. Preferably, the air inlet pipe 10 and the air outlet pipe 11 of the present embodiment are oppositely disposed at two sides of the furnace body 1, so that the air entering the heating cavity 9 from the air inlet pipe 10 can be fully contacted with the wall of the combustion chamber 2, the heating process of the air is accelerated, and the heating effect is improved. In addition, an exhaust fan 12 is connected to one end of the air inlet pipe 10 far away from the heating cavity 9, and the speed of the external air entering the heating cavity 9 can be reasonably controlled by the exhaust fan 12, so that the using effect is optimized.

Through the arrangement, when in use, a corresponding cooker for cooking can be installed on the combustion chamber 2, so that the combustion chamber 2 at the moment forms a relatively closed combustion cavity. When fuel burns and forms flame in the combustion chamber 2, the flame and high temperature flue gas constantly impact the wall of the combustion chamber 2, meanwhile, outside air is sucked into the heating chamber 9 through the exhaust fan 12, cold air entering the heating chamber 9 is constantly contacted with the wall of the combustion chamber 2 to realize heat exchange, and finally heated hot air is discharged through the air outlet pipe 11 to flow to a place needing to utilize the hot air. Therefore, the heating cavity 9 for heating cold air is directly arranged on the periphery of the combustion chamber 2, and air is used as a heating medium, so that the heat utilization rate and the heating effect during fuel combustion can be improved on the basis of accelerating the whole heating process.

In addition, the lateral wall of furnace body 1 of this embodiment is netted orifice plate, and this netted orifice plate has the panel of a plurality of louvres for surface array distributes, and partial heat can be discharged through the louvre when the fuel burning to obtain partial heat from the outside of furnace body 1 in order to improve the heating effect.
