Accordingly, the discharged fuel C is advanced, and at this time, the fuel C is pressed by the fuel C to push the lower plate 22b toward the upper plate 22a and return to the original position by the elastic force of the leaf spring 22c.

The recollection chamber 40 provided at the lower portion of the combustion chamber 10 includes a crushing member 41 in which ash falling from the combustion chamber 10 accumulates, and an injection member 45 provided in a plane of the crushing member 41. )

The shredding member 41 is first accumulated ash (C) falling from the combustion chamber 10 and passes through the through groove 44 formed in the shredding member 41 to be discharged to the re-discharge unit 50 to be described later .

In addition, the crushing member 41 crushes the ash (C) of a predetermined size or more, the screw thread (41a) formed on the outer circumferential surface of the crushing member 41 meshes with the rotating shaft (Ma) of the driving unit (Mb) Meshes in the state of being raised in the through groove 44 while being rotated in the forward or reverse direction along the direction of the rotation axis Ma of the driving unit M, thereby crushing the ash C. By the wing part 46 provided in the lower part, it is crushed again, and is conveyed to the redistribution part 50.

Furthermore, the injection member 45 for injecting the air introduced from the air inlet portion 43 formed inside the central axis 42 of the shredding member 41 is provided.

The injection member 45 is provided in plural in the plane of the shredding member 41 and made of a circular or polygonal, and is stacked at the plane of the shredding member 41 while rotating at the same time when the shredding member 41 rotates Air is injected into the ash (C).

At this time, it is preferable to satisfy the condition that the ash (C) is spread throughout the recollection chamber 40 while controlling the injection strength so that the ash (C) is not introduced into the combustion chamber 10 by the injected air.

The air injected from the injection member 45 may inject the air sucked from the outside to lower the temperature of the combustion chamber 10 and the recollection chamber 40.

The finely crushed and conveyed ash C in the recollection chamber 40 is transferred to the redistribution unit 50 and discharged to the collection box 52 provided outside the stove 100.

At this time, the redistribution unit 50 is composed of a screw rod 51 so that ash (C) is smoothly discharged toward the collection box 52, and the ash (C) is discharged toward the collection box 52 by the screw rod 51. will be.

Looking at the operation sequence of the present invention made as described above are as follows.

Check the time consumed a certain amount of solid fuel (C) by the heat source pre-ignited inside the stove 100 and input the confirmed time to the control unit after a certain time, the driving unit is operated by the control unit fuel transfer unit ( 30) is rotated.

The fuel transfer portion 30 has the fuel (C) discharged from the fuel storage portion 20 between the adjacent guide bar 32, the conveyor belt 31 of the fuel transfer portion 30 is rotated guide bar Advance (32) to transfer a certain amount of fuel (C) to the fuel input portion 12 of the stove (100).

The opening / closing member 12a provided in the fuel input unit 12 is pushed inward by the load of the transferred fuel C, and the fuel C is transferred to the combustion chamber 10 and burned by a heat source.
