Therefore, in recent years, the use of cheap and environmentally friendly pellets fuel has been increasing, and pellets fuel is also used in the hearth for heating the room.

The pellet stove using the pellet fuel as described above is disclosed in Japanese Patent Application Laid-Open No. 10-1271748 (Registration date 2013.05.30) and No. 10-1564844 (Registration date 2015.10.26), and most of these pellet stoves The external air required for the combustion of the pellet fuel flows through the vent hole formed in the bottom surface of the furnace where the pellets are burned and the pellet fuel is burned. Is heated and exchanged with the air supplied to the blowing fan, and the heated air is sent to the discharge port to heat the room.

That is, the pellet stove disclosed in the above-mentioned prior art supplies the pellet fuel using a transfer device such as a fuel supply device in the storage hopper, with the furnace at the bottom of the main body, When the heat generated by the flame is generated, the air sucked from the indoor side passing through the heat exchange line is heat-exchanged to be heated to a predetermined temperature, and the air (or heating heat) So that it can be discharged to the room side through the heating pipe.

Fig. 1 is a perspective view of a conventional pellet stove, Fig. 2 is an exploded view of a conventional pellet stove, and Fig. 3 is a sectional view of a conventional pellet stove.

1 to 3, the conventional pellet stove forms a closed space (a) for air circulation at the lower end side of the furnace 10, while a box-like structure is provided at the lower end side of the closed space (a) The ash receptacle 20 is fixedly installed so that the ashtray 20 is caught during the combustion of the pellet fuel in the furnace 10 to collect the residue (for example, fly ash) scattered.

At this time, in the closed space (a) for air circulation formed at the lower end of the furnace (10), various residues (for example, ash, clinker, slag Slag) and the like are discharged and can be dropped into the ashtray 20.

However, when a large amount of residue is accumulated in the closed space (a) when the pellet stove is operated for a long time, there is a problem that the residue accumulated in the closed space (a) can not fall on the ash receiver 20, Therefore, conventionally, the air circulation through the vent hole 11 of the furnace 10 is not properly performed, and the combustion efficiency with respect to the pellet fuel in the furnace 10 is lowered.

Particularly, since the ashtray 20 applied to the conventional pellet stove has a fixed structure in which the separation is not free, there is a considerable difficulty in processing the residue accumulated in the closed space (a).

3, when the furnace 10 and the ashtray 20 are separated by the partition 30, the furnace 10 is installed in the installation hole 301 provided in the partition 30, So that various residues generated by the burning of the pellet fuel in the furnace 10 can be prevented from entering the ashtray 20 through the bottom of the ashtray 20, A part of the residue is accumulated in the closed space a and the blast furnace 10 is first removed from the partition 30 and the installation hole 31 of the partition 30 is removed, The suction pipe of the vacuum cleaner enters the bottom of the air suction space (a) or the residue accumulated in the ash receiver 20 is removed.

However, the installation hole 31 of the partition 30 is narrow and the inconvenience of removing the ash using a separate cleaning tool such as a vacuum cleaner can not be avoided, The air is not smoothly circulated from the closed space a to the air hole 11 of the blast furnace 10 and is interfered with, The combustion efficiency with respect to the pellet fuel in the furnace 10 was inevitably lowered.
