Description

{USING PELLET STOVES}

The present invention relates to a stove using pellets, and more particularly, to a stove using a pellet, and more particularly, to a pellet stove which uses a gravity and a convection to burn pellets so as to have a high thermal efficiency with a small heat source, The present invention relates to a fireplace using pellets which can be used for heating indoor.

In recent years, wood-pellets fuels have come into the spotlight, where fuel costs are low and environmental and human health are not harmed. Wood pellets are eco-friendly products that process wood by-product, sawdust, and reduce carbon dioxide formed into small granular pellets at high temperatures and pressures using a pellet molding machine. In addition, since the lignin component in the wood is melted and molded into pellets without any additive in the pellet process, manufacturing cost is reduced, and it is much lower than the cost of purchasing petroleum or coal used as fuel, which is widely used worldwide.

Conventional stoves using such pellets are disclosed in Japanese Utility Model Registration No. 450891 (name: Pellet-free pellet stove), Utility Model Registration No. 4485540 (name: pellet stove), Patent Publication No. 2009-68265 (titled: Multifunctional Pellet Combustor ) Was released. The conventional stoves include a storage container for storing and storing the combustion-passing pellet fuel for igniting and burning the pellet fuel, and a transfer device such as a screw or a conveyor belt for transferring the pellet fuel received in the storage container to the combustion column.

However, the above-described conventional techniques have a disadvantage in that a structure is complicated and manufacturing cost is increased because a means for transferring fuel is required.

In order to solve the above-mentioned problems, in Korean Patent Registration No. 1258023, pellets are contained in a reservoir, and a grill is installed at the bottom of the pellet. When the pellets are ignited at the bottom of the grill, the pellets are burnt sequentially from the bottom of the reservoir, A burning configuration has been proposed.

This is characterized in that there is no conventional conveying device, and the pellets contained in the reservoir are burnt in the lower part of the reservoir and are continuously moved downward by their own weight in the process of falling below the grill.

The conventional patent No. 1258023 can not reduce the gap between the grill and the bottom much because the burning pellets fall down vertically to serve as a heat source for burning the pellets above the grill.

Therefore, when a large amount of pellets are accumulated on the bottom of the grill, it is necessary to remove the pellets.

In addition, there is a disadvantage in that the heat of the pellet being burned upwardly collides with the air required for the combustion to be introduced into the air inlet hole and thus the air can not flow smoothly. Since the bottom of the storage container is blocked by crossing with the grill, The pellets that are burning can not fall smoothly, and the grill may be clogged.

In addition, since the storage grill and the combustion space are integrally provided in the hearth, if one of them fails, the hearth can not be used. Moreover, since the hearth and the combustion space are not separated from each other,

Further, there is a problem in that it is difficult to control the pellet combustion due to the adjustment of the amount of the pellet fuel and the fixed spacing between the combustion space and the grill, so that the continuous heating effect can not be obtained.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the problems described above, and it is an object of the present invention to provide a pellet in which a pellet made by compressing sawdust is placed in a fuel cell and burned sequentially from the bottom, And the stove is provided with a space where the stove is retained so that the combustion mechanism can be separated from the stove, thereby providing a stove using the pellet which is easy to repair and move.
