The conventional stove construction includes a storage container for storing and storing combustion-passing pellet fuel for igniting and burning pellet fuel, and a transfer device such as a screw or a conveyor belt for transferring the pellet fuel stored in the storage container to the combustion column.

However, the conventional stove using the pellet fuel has the following problems by providing a transfer device for transferring the pellets.

There is a problem that the operation cost is not reduced but the adverse effect is increased and the supply of the pellet fuel is stopped when the power supply is cut off because the power is supplied to operate the motor of the transfer device.

Further, by providing a large reservoir separately, there is a problem that the installation space is limited due to the problem that the volume of the hearth increases, and the assembly and disassembly of the hearth is not easy.

In addition, due to the increase in the volume of the hearth due to the large reservoir, there arises a problem that it is difficult to install in a residential space having a small area such as a general house or a restaurant.

Also, there is a problem that the user's life is not easy due to operation noise of a motor and a screw or a conveyor operated by a power source.

In addition, there was a problem that the livestock kept in the housing decreased in breeding status due to the stress caused by the operating noise.

As shown in FIG. 3, the combustion member 50 is provided with a "V" -shaped portion 52, which is hooked on the lower end of the fuel intake passage 42, And is positioned above the filter cover 46-1 of the refill container 46. The filter cover 46-1 of the refill container 46 is disposed at the upper portion of the filter cover 46-1.

In addition, the filtering section 52 includes a plurality of filtering sections 54 integrally formed at predetermined intervals so as to discharge the fuel uniformly.

In addition, it is preferable that the interval of the filtering piece 54 is narrow so that the air is circulated at one side thereof, and the interval at the other side is wide so that the fuel is discharged constantly from the combustion passage 44.

The circulation unit 60 includes an inlet 62 connected to the combustion passage 44 of the combustion unit 40 so as to be integrally connected with the combustion passage 44, And a circulation cover 66 provided at an upper portion of the circulation passage 64 and recirculating the heat to the lower portion of the circulation passage 64. The circulation passage 64 is provided in the upper portion of the circulation passage 64, And an outlet 68 on the other side of the lower portion for discharging the smoke.

In addition, a communication (not shown) coupled to the outlet may be further provided to discharge the smoke discharged from the outlet to the outside.

In addition, the fuel 12 according to the present invention may be pelletized, but may use a common solid fuel at the user's option. For example, small sized coal or finely crushed wood or charcoal may be used.

In addition, the storage unit 20, the combustion unit 40, and the circulation unit 60 are illustrated as being formed in a rectangular barrel. However, the barrel may have a cylindrical shape or a polygonal shape of a triangle or more by a user. As well as the technical ideas of

As shown in FIGS. 4 and 5, the furnace of the present invention as described above burns fuel by non-dynamic force to circulate heat.

First, as shown in FIG. 4A, the fuel 12 is charged into the fuel supply passage 42 of the combustion section 40 by the storage section 20 in which the fuel is stored, and is stacked.

Then, the stacked fuel 12 is hooked on the combustion member 50 and the fuel 12 is loaded to a certain extent of the combustion passage 44.

At this time, the fuel 12 is stacked on the upper portion of the filter cover 46-1.

The fuel 12 is ignited by an ignition means (not shown) through an ignition port 44-1 provided in the upper portion of the combustion passage 44. [

In this case, the ignition means is preferably a torch.

Then, as shown in FIG. 4B, when the fuel is ignited, the fuel is burned and the burned heat is introduced into the circulation unit 60.

At this time, since the circulation unit 60 is maintained in the closed state, the heat is introduced from the combustion unit 60, the air of the circulation unit 60 is burned by the heat and the smoke is discharged naturally so that the circulation unit 60 is in a vacuum state .

Therefore, since the heat of the combustion unit 40 and air are sucked in the circulation unit 60, air is introduced into the air inlet 48 provided at one side of the combustion unit 40, The fuel is injected constantly through the combustion tube 56 of the fuel tank 56 to push the fuel stack.

Therefore, the loaded fuel 12 continues to flow in a certain amount, and the burned fuel 12 can be burned more easily by the air blowing in the combustion tube 56, thereby maximizing the burning rate of the fuel 12. [

In addition, the ash of the combusted fuel 12 is collected into the refueling container 46 through the filter cover 46-1.

5 and 6, the heat generated by the combustion of the fuel 12 in the combustion section 40 is circulated through the air in the combustion section 40 by the circulation section 60 maintaining the vacuum state And is constantly introduced through the circulation passage 64 due to the sucking.

The heat is discharged to the inside of the upper portion of the circulation portion 60 through the circulation passage 64.

At this time, the heat is circulated to the lower portion of the circulation unit 60 along the upper portion of the circulation unit 60 by the circulation cover 66 provided at an upper portion of the circulation passage 64 at a predetermined angle.

Further, the circulation wall 70 is further provided on both sides of the circulation passage 64 so that the heat is circulated downward and circulated to the space below the circulation wall 70 toward the circulation wall side.

The heat is circulated inward once more by the partition 76 provided on the front surface of the discharge part 68, and foreign substances such as ashes are caught by the partition 76 to be blocked.

The heat once further circulated by the partition wall 76 is completely burned in the circulation part and is discharged to the communication pipe 80 through the discharge port 68.

That is, in the non-powered circulation hearth 10 according to the present invention, the fuel of the storage part 20 is automatically supplied to the combustion part 40 by a predetermined amount, and is constantly burnt by the combustion member 50 in the combustion path 44 The refuse ash is collected, and the burned heat is circulated through the circulation unit 60 to be completely burned and discharged to the discharge port 68.

Further, the ignited fuel 12 is completely burned, the circulation unit 60 is sealed, and the air of the circulation unit 60 is burned by the heat, so that it is evacuated to continue the heat and the air of the combustion unit 40 And is continuously circulated without power by ignition once until the combustion of the fuel 12 is ended.

Therefore, the power-free circulation furnace according to the present invention does not need to include a separate power unit and fuel injecting unit since the fuel is always constantly injected by the storage unit and the fuel is continuously combusted by circulation by ignition.

Further, the fuel is introduced into the combustion passage at a constant rate by the filtering portion of the combustion member, air is uniformly introduced by the combustion tube, and the fuel is blown into the combustion passage, so that the fuel can be constantly combusted.

In addition, the structure is simple, mass production is easy, maintenance and repair are easy with less failure and damage.

In addition, the combustion rate of the fuel can be maximized by the circulation system, the heat can be maximally circulated by the circulation of the circulation unit, thereby maximizing the heat efficiency and minimizing the discharge of dust or ash.

The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention as set forth in the appended claims. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
