An auxiliary cap 78 is detachably attached to the part. The auxiliary air introduction pipe 76 may be provided only on one side of the exhaust housing 12.

  Thus, when the auxiliary cap 78 is removed, the auxiliary air introduction port 70 is opened, outside air is introduced through the auxiliary air introduction port 70, and part of the introduced air is supplied to the combustion chamber 4. However, the remainder is discharged to the outside through the exhaust housing 12 and the exhaust chimney 16. In addition, in a state where the auxiliary cap 78 is attached, the auxiliary air introduction port 70 is closed, and the outside air is not introduced through the auxiliary air introduction port 70. When a small amount of air can be supplied through the air introduction holes 44 and 46 of the left and right door members 24 and 26, the auxiliary air introduction port 70 can be omitted.

  A heating plate 80 is provided on the upper surface of the stove body 2. The heating plate 80 is made of a metal plate such as an iron plate, and is fixed to the upper surface of the stove body 2 by welding or the like. The heating plate 8 is heated by the heat from the stove body 2 and can be used for cooking by placing a cooking pan or the like, and can be used for boiling hot water by placing a kettle or the like. In addition, the heating plate 80 can be used for grilled dishes and the like, and various uses are possible.

  The stove body 2 is installed on the floor surface 86 (or the ground) or the like via the front leg body 82 and the rear leg body 84. The front leg body 82 and the rear leg body 84 have substantially the same configuration. Hereinafter, the front leg body 82 (rear leg body 84) will be described. The front leg body 82 (rear leg body 84) is grounded to the floor surface 86 and the like. The support plate 92 is supported on the ground plate 88 via a plurality of (four in the specific example) support columns 90, and the stove body 2 is fixed to the support plate 92 by welding. . The front part of the stove body 2 is fixed to the support plate 92 of the front leg body 82, and the rear part thereof is fixed to the support plate 92 of the rear leg body 84. In order to reinforce the fixing of the stove body 2, a substantially L-shaped reinforcing member 94 is provided between the stove body 4 and the support plate 92.

  This wood stove is used as follows, for example. In order to burn the soot 96, the front cap member 64 is removed, and the open / close door 22 (left and right door members 24, 26) is rotated outward to open the soot opening 6, and through the open soot opening 6 What is necessary is just to put the soot 96 which should be burned into the combustion chamber 4, and to combust it (it should be noted that after the soot 96 is combusted, the door 22 is closed). When the soot 96 is put into the combustion chamber 4 through the soot inlet 6, the introduced soot 96 is stacked on the upper side of the intake air intake pipe 60 as shown in FIG. In this embodiment, since the intake introduction pipe 60 is disposed so as to be inscribed in the inner peripheral surface of the stove body 2, a gap is generated between the stove 96 and the stove body 2 and the intake introduction pipe 6. Such a gap becomes a space through which the combustion air flows, and thus a space for the combustion air can be secured even at the bottom of the pile 96 stacked.

  During combustion, air (outside air) sucked through the intake pipe 60 is supplied to the combustion chamber 4 from the air holes 68 as combustion air. The air thus supplied flows through the gap between the stacked bowl 96 and the stove body 2 and the intake pipe 60, and sufficient air can be supplied to the stacked bowl 96. In this wood stove, since the air hole 68 is provided only in the front portion of the intake air introduction pipe 60, the outside air (air) is not excessively supplied to the combustion chamber 4. Further, the combustion exhaust gas generated by the combustion of the soot 96 flows toward the exhaust chimney 16 behind the combustion chamber 4, flows through the exhaust opening 20 and the exhaust housing 12, and is discharged from the exhaust chimney 16 to the outside.

  In order to suppress the combustion of the soot 96, the front cap member 64 is attached to the front end portion of the intake air introduction pipe 60, and combustion air is supplied through the air introduction holes 44, 46 of the left and right door members 24, 26. Good. When the front cap member 64 is attached, the suction port of the suction introduction pipe 60 is closed, and the supply of outside air (air) through the suction introduction pipe 60 is stopped. Further, the left and right sub-gripping members 56 and 58 are gripped to rotate the left and right air adjustment plates 40 and 42, and the overlapping ratio between the adjustment holes 52 and 54 and the air introduction holes 44 and 46 of the left and right door members 24 and 26. Is adjusted, the outside air (air) is supplied to the combustion chamber 4 through the air introduction holes 44 and 46 whose openings are adjusted. At this time, the supply amount of the air supplied through the air introduction holes 44 and 46 is smaller than the supply amount of the air supplied through the intake air introduction pipe 60. Thus, by reducing the supply amount of the air, the 薪 96 Combustion can be suppressed and the generation of combustion heat can be reduced.

  In order to further suppress the combustion of the soot 96, the supply of the combustion air through the air introduction holes 44 and 46 of the left and right door members 24 and 26 is stopped and the combustion air is supplied through the auxiliary air introduction port 70. That's fine. When the left and right auxiliary gripping members 56 and 58 are gripped and the left and right air adjustment plates 40 and 42 are rotated to block the air introduction holes 44 and 46 of the left and right door members 24 and 26 with the left and right air adjustment plates 40 and 42, The introduction of air through the air introduction holes 44 and 46 of the door members 24 and 26 is stopped. When the auxiliary cap 78 is removed, the auxiliary air introduction port 70 is opened, and the outside air (air) in the exhaust housing 12 is supplied through the auxiliary air introduction pipe 76 and the auxiliary air introduction port 70, and thus one of the supplied air is supplied. The part is supplied to the combustion chamber 4 and used for combustion of the soot 96, and the remaining part of the air flows into the exhaust chimney 16 together with the combustion exhaust gas and is discharged to the outside. At this time, the amount of air supplied to the combustion chamber 4 through the auxiliary air introduction port 70 is so small that the combustion state of a small flame is maintained, and such an air supply state is maintained during sleep at night. Be drunk.

  In order to remove the ash accumulated in the combustion chamber 4, after the combustion is finished, the front cap member 64 and the rear cap member 66 are removed from the intake pipe 60, and in this state, an ash removal brush (not shown) is removed. It is only necessary to insert from the front end opening (or rear end opening) of the intake air inlet pipe 60 and move it backward (or forward) to push out the ash inside, and thus the ash can be easily discharged. . The ash in the combustion chamber 4 may be pushed out as described above after being dropped into the intake pipe 60 through the air hole 68.

  As mentioned above, although one embodiment of the wood stove according to the present invention has been described, the present invention is not limited to such an embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, when a large amount of combustion air is supplied, it is supplied through the intake pipe 60, and when a small amount of combustion air is supplied, it is supplied through the air introduction holes 44, 46 of the left and right door members 24, 26. However, instead of such a configuration, a front cap member (not shown) having an opening degree adjusting function is detachably attached to the front end portion of the intake air introduction pipe 60, and the opening degree of the front cap member is adjusted. In this case, the air introduction holes 44 and 46 of the left and right door members 24 and 26 can be omitted.
