The second charging port 30 is provided with a lid 31 that can be opened and closed. When the wood stove S is used, the lid 31 is closed. When the second charging port 30 is used, the soot can be stored in the cylindrical body 14a, so that it is not necessary to repeatedly perform the soaking operation of the soot, and the complexity can be reduced accordingly.
[0016]
An ash removal outlet 15 is provided on the front side of the placing portion 13, and ash is scraped from the ash removal outlet 15 into a drawer-like ash receiving portion 16 provided at the lower portion of the placement portion 13. Yes.
[0017]
In addition, the main body 10 includes an inclined air supply pipe 40 having an outlet 41 that can supply outside air from obliquely upward toward the upper center of the mounting portion 13, and the outlet 41 is a center line P of the mounting portion 13. A plurality (a pair in the embodiment) are provided so as to be symmetrically arranged. Specifically, the inclined air supply pipes 40 are provided on the left and right sides of the main body 10, the inflow ports 42 are exposed to the outside of both sides of the main body 10, and the outflow ports 41 are positioned above the placement unit 13. The inclined air supply pipe 40 extends along the outer side of the main body 10, and an outside air inlet 42 is located on the lower side of the main body 10. In other words, the inlet 42 side of the inclined air supply pipe 40 is extended so as to extend downward on the side of the main body 10 to form the extending portion 43, and the inlet 42 is directed to the ground. The outlet 41 faces the opening at the lower end of the cover part 14 and is arranged symmetrically with respect to the center line P of the placement part 13 so as to face each other.
[0018]
Furthermore, the main body 10 has a horizontal air supply pipe 50 having an outlet 51 that can supply external air horizontally toward the upper center of the mounting portion 13, and the outlet 51 is a center line P of the mounting portion 13. A plurality (a pair in the embodiment) are provided so as to be symmetrically arranged. Specifically, each horizontal air supply pipe 50 includes an inflow port 52 and an outflow port 51, the inflow port 52 is provided in the lower part of the main body 10, and the outflow port 51 is centered on both sides of the mounting portion 13 so as to face each other.

While visually checking the flame from the window 22, the intensity of the flame can be adjusted, and the inflow of outside air can be suitably adjusted.
[0020]
Therefore, when using the wood stove S of the present invention, as shown in FIGS. 2 to 4, the firewood is placed on the placement portion 13 and ignited, as shown in FIGS. The soot is stored and ignited. The soot loaded in this way and placed on the placement unit 13 starts to burn with the outside air supplied from the horizontal air supply pipe 50 and the inclined air supply pipe 40.
In this case, since the outside air is supplied horizontally from the outlet 51 of the horizontal air supply pipe 50 toward the upper center of the mounting portion 13, the outside air is supplied all along the surface of the mounting portion 13. Primary combustion is promoted and generation of unburned gas is reduced. Moreover, since the outflow port 51 is arrange | positioned symmetrically with respect to the centerline P of the mounting part 13, the convection of gas will be stabilized regularly, Therefore Combustion is performed smoothly.
[0021]
The gas containing unburned gas that has not been burned rises upward from the placement unit 13, but the outside air flows from the outlet 41 of the inclined air supply pipe 40 toward the upper center of the placement unit 13 obliquely from above. Supplied. Therefore, the unburned gas is burned with high efficiency by supplying sufficient air above the mounting portion 13, and exhaust of the unburned gas from the chimney 17 is reduced. In addition, since the outside air is supplied obliquely from above, the unburned gas is pushed back to the primary combustion side and burned. In this respect, the unburned gas is burned with high efficiency, and the unburned gas is discharged. Can be reduced. Furthermore, since the outflow port 41 is disposed symmetrically with respect to the center line P of the mounting portion 13, the convection of gas is regularly stabilized, and therefore combustion is performed smoothly.
[0022]
Further, in this case, since the inclined air supply pipe 40 is extended to the outside of the main body 10, the backflow of the exhaust gas hardly occurs and the combustion is performed smoothly. Specifically, since warmed air (including exhaust gas) in the main body 10 tends to go upward, when the exhaust gas tries to flow backward from the outlet 41 of the inclined air supply pipe 40, the inlet 42. Is directed toward the ground surface, it becomes difficult for warm exhaust gas to flow out of the inlet 42. For this reason, the exhaust gas is exhausted from the chimney 17, and the backflow from the air supply pipes 40 and 50 can be prevented unless the pressure inside the main body 10 becomes abnormally high for some reason.
[0023]
Furthermore, since the cover part 14 is provided above the center of the mounting part 13 and the outlet 41 of the inclined air supply pipe 40 faces the opening at the lower end of the cover part 13, unburned gas is suppressed by the cover part 14. The air rises and becomes difficult to convect, and the air from the outlet 41 of the inclined air supply pipe 40 flows into the restrained and stopped unburned gas, so that secondary combustion is reliably performed.
As a result, good secondary combustion can be performed, unburned gas is reduced, and unburned gas in the exhaust gas exhausted from the chimney 17 is reduced.
[0024]
5 and 6 show a wood stove S according to the second embodiment of the present invention. The soot stove S is formed in substantially the same manner as the soot stove S according to the first embodiment, but unlike the first embodiment, the cover portion 14 is formed in a cup shape, and the inside of the combustion chamber 11 Is housed in. The operation and effect are the same as those in the first embodiment. In this case, a space is created on the upper side of the main body, which can be used for cooking and the like.
[0025]

Can be made difficult to pollute the surrounding environment.
[0026]
In addition, since the outside air is supplied obliquely from above, the unburned gas is pushed back to the primary combustion side and burned. In this respect, the unburned gas can be burned with high efficiency, and the unburned gas from the chimney can be burned. Exhaust of combustion gas can be reduced. Furthermore, since the outlet is arranged symmetrically with respect to the center line of the mounting portion, the convection of the gas is regularly stabilized, and therefore combustion can be performed more smoothly.
Furthermore, it is possible to burn unburned gas with high efficiency by supplying sufficient air with a simple structure in which an inclined air supply pipe is provided without using a catalyst as in the prior art. Can be reduced.
[0027]
In addition, when the inclined air supply pipe is extended along the outer side of the main body and the outside air inlet is located on the lower side of the main body, the backflow of the exhaust gas hardly occurs from the inclined air supply pipe. The combustion can be performed reliably.
Further, a plurality of horizontal air supply pipes having outlets capable of supplying outside air horizontally are provided toward the upper center of the mounting part so that the outlets are arranged symmetrically with respect to the center line of the mounting part. In this case, it is possible to supply the entire outside air along the surface of the mounting portion, promote primary combustion, and reduce generation of unburned gas. Further, since the outlet is arranged symmetrically with respect to the center line of the mounting portion, the convection of gas is regularly stabilized, and therefore combustion can be performed smoothly.
[0028]
Furthermore, when a cylindrical cover is provided at the upper center of the mounting part and the outlet of the inclined air supply pipe faces the opening at the lower end of the cover, the unburned gas is suppressed by the cover and rises. As a result, it becomes difficult to convect, and air from the outlet of the inclined air supply pipe flows into the unburned gas that has been restrained and stopped, so that secondary combustion can be performed reliably.
In addition, when the cover is formed as a spout opening that can be opened and closed at the upper end, and configured with a cylindrical body that stores the spear that has been thrown in, the spear can be stored, and the frequency of throwing the spear can be reduced, There is an effect that labor can be saved and complexity can be reduced.
