The present invention is a top-down stove that uses bituminous coal as a fuel, and forms a combustion cylinder so that the stole can be placed at the bottom of the hopper at the top, and forms an opening and closing disc, a communication support plate, and a curved tube at the bottom, The present invention relates to a bituminous coal stove which can maintain a constant temperature at all times by forming a reverse wind preventing piece and has good thermal efficiency.

Conventional stoves mainly use petroleum or anthracite coal, but as the energy depletion phenomenon becomes clear, it accelerates the development of a combustor for alternative fuels.

The present invention has been devised in view of such a situation, and it is possible to reduce fuel costs by effectively using inexpensive bituminous coal without using expensive fuel such as petroleum or anthracite coal, and to improve thermal efficiency by completely burning. It will be able to perform much better than the stove.

This will be described in detail with reference to the accompanying drawings.

1 is a rectangular bottom plate. 2 is a cylindrical base, in which the mounting jaw 3 is formed at the outer periphery of the upper surface thereof, and the downwardly inclined surface 4 is formed at the inner side of the mounting jaw 3 with the through hole 4 'at the center thereof. ), The opening and closing disc (6) is adjusted to the handle (5) from the outside to install it on the top of the bottom plate (1). 7 is a combustion cylinder of the cylindrical body covering the lid (9 ') at the top and forming an air regulator (8) on the upper one side so that the inner circumferential surface is inscribed in the outer periphery of the mounting jaw (3). 9 is a communication support plate protruding the communication insertion portion 10 in the center, and a plurality of support rods 10 'are radially extended at the lower end of the inserting portion 10 so that the support rods 10' are placed on the upper surface of the mounting jaw 3. In the insert portion 10 is inserted into the curved tube 11 penetrating the outside of the combustion cylinder (7). 12 is a mounting jaw attached to the inner circumferential surface of the upper part of the combustion cylinder 7 to fix the ring body 13 to the upper end thereof. 14 is the primary communication inside The mold mounting plate 15 is inserted and the rostol 16 'having a plurality of through holes 16 is placed therein. 17 is a hopper, the lower end of which is installed in the primary combustion cylinder 14, and the upper end of the hopper is in close contact with the inner surface of the combustion cylinder 7. 18 is an exhaust pipe, which forms a preheating plate 19 at the lower end, forms a backflow preventing piece 20 in a zigzag, and protrudes the outlet 21 at the upper center. Reference numeral 22 is a return.

The present invention configured as described above is a solid alcohol, etc. in the preheating plate 19 to ignite to heat the inside of the exhaust cylinder (18). Then open the lid (7 ') and put a small amount of fuel in the primary combustion cylinder (14), and after igniting the required amount of fuel in the hopper (17) starts a full-fledged combustion and the air introduced into the air regulator (8) With the suction force of the exhaust cylinder 18, it is combusted in the primary combustion cylinder 14 and descends into the combustion cylinder 7 and continues to be combusted to the lower end of the communication support plate 9 and through the curved tube communication 11 through the insertion section 10. When it reaches (18), the residual gas in the exhaust cylinder 18 is completely burned by the primary preheated heat of the exhaust cylinder 18, and the last small amount of heat is discharged to the outside through the discharge port 21.

At this time, the burned ash is dropped as it is and is accumulated on the opening and closing disc 6, but completely burned down and the ash amount is extremely small, and after about 15-20 hours of use, when the handle 5 is turned, the opening and closing disc 6 is rotated and accumulated thereon. Ash is to fall to the ash tray 22.

On the other hand, the lower end of the hopper 17 receives a lot of heat, the primary combustion communication 14, the rostol 16, the mounting plate 15, the communication support plate 9, the curved tube communication 11 and the like are formed by casting It can be lifted up and disassembled or assembled so that if only some of them are broken, only the parts can be replaced.

In addition, not only accelerates combustion by heating the exhaust cylinder 18 primaryly, but also the heat burned in the primary combustion cylinder 14 is diffused downward through the rostol 16 to be moved into the combustion cylinder 7 and thus the combustion cylinder. Reburned in (7) and completely burned the residual gas in the exhaust cylinder (18), the thermal efficiency is good, and always maintain a high temperature of 500-600 ℃ in the combustion cylinder (7) to always keep the room temperature constant Temperature control is possible, and there is no inconvenience, such as placing a separate container in the communication because the internal temperature of the stove leads to severe fluctuations and water is generated inside the stove as in the prior art.

In addition, by forming the backwind prevention piece 20 in a zigzag, it is completely solved the disadvantage that the combustion is not well caused by the strong wind of the outdoors.

The present invention is easy to ignite and can be used for a long time by injecting fuel once, and can keep the room temperature at a constant temperature, and since it is completely burned, communication is not blocked, and odor and smoke peculiar to bituminous coal are generated by incomplete combustion. It has the advantage of not being.
