1 to 4 , the firewood 1 for camping according to an embodiment of the present invention may include a furnace part 100 and an outer housing 200 formed outside the furnace part 100 .

First, the furnace part 100 may include a combustion chamber 110 in which fuel is loaded and combusted, and, as will be described later, an ash receiving part 190 formed to collect the burnt and remaining ash may be formed at the bottom, The furnace part 100 may be divided by a loading frame 141 formed to load fuel, and may be divided into a combustion chamber 110 and a re-receiving part 190 .

The furnace unit 100 may include a lower air passage hole 120 at the lower portion so that the air inside the combustion chamber 110 can pass to the outside, and the air flow of the air rising from the outside or the lower portion is provided at the upper portion of the combustion chamber. It may include a plurality of upper air passage holes 130 to be introduced into the (110).

The upper and lower air passage holes 120 may be formed in a circular hole shape on the side and rear surfaces of the furnace part 100 except for the front surface.

The outer housing 200 may be formed to be spaced apart from the periphery of the furnace part 100 on the side and rear surfaces except for the front side of the furnace part 100, and is spaced between the furnace part 100 and the outer housing 200. The air passage 300 as much as the interval may be formed in a 'C' shape. In addition, external air inlets 210 may be formed at regular intervals in the lower portion of the outer housing 200 to allow external air to be introduced.

In addition, the outer housing 200 may have an opening and an opening formed on the upper surface so that the heat emitted from the combustion chamber 110 is discharged to the outside, but is not limited thereto.

At this time, since the cold air introduced from the outside is in contact with the heat emitted from the combustion chamber 110 and an upward airflow is formed, the external air flowing in from the external air inlet 210 is moved by the upward airflow to the upper air passage hole 130 . air flow may be formed to move to It may be introduced into the air passage 300 .

At this time, the size of the hole in which the lower air passage hole 120 formed in the lower portion of the furnace part 100 is formed is smaller than that of the external air inlet 210 formed in the outer housing. , the flow rate of the air introduced from the outside may be greater than the flow rate of the air of the furnace unit 100 introduced into the air passage 300 through the lower air passage hole 120 .

That is, the air flowing in from the outside forms an upward airflow due to the heat that meets as it flows into the air passage 300, and due to the pressure difference with the lower air passage hole 120 formed in the furnace part 100, the furnace part ( 100) It is possible to allow the internal air to flow into the air passage (300).

More specifically, as shown in Fig. 2, the campfire wood 1 of the present invention has an air passage 300 that is an air flow space between the furnace part 100 and the outer layer through the outer housing 200. Since it is formed in a structure, cold air introduced from the outside through the external air inlet 210 is introduced into the combustion chamber 110 through the upper air passage hole 130 , and the emitted heat can be raised upward.

In addition, the heat emitted from the combustion chamber 11 may be discharged to the air passage 300 through the lower air passage hole 120 so that heat is applied to the undecomposed fuel layer in the combustion chamber 11 .

At this time, the hot air discharged to the air passage 300 through the lower air passage hole 120 meets the cold air flowing in from the external air inlet 210 to form an upward airflow, and then through the upper air passage hole 130 again the combustion chamber ( 110), it can have the effect of completely burning the undecomposed fuel layer.

Meanwhile, referring to FIGS. 3 to 4 , the lower air passage hole 120 may further include a flow rate control unit 121 to control the flow rate of air passing therethrough, and the flow rate control unit 121 may include a furnace unit ( 100) is provided in a circular shape on the outside of the lower air passage hole 120 formed at the lower end, and can pass through the lower air passage hole 120 using the adjustment dial 121b formed in the flow rate control unit 121.

At this time, the air flow inducing film 310 is formed in a sector shape on the inner surface and upper portion of the outer housing 200 to form a curve, so that a vortex of the air flow is prevented from being generated.

At this time, the upper air passage hole 130 may be formed with a plurality of holes so that the upward air flow in the air passage 300 can be sufficiently introduced into the combustion chamber 110 .

In addition, referring to FIG. 6 , an airflow forming unit 160 is formed in the lower portion of the air passage 300 according to an embodiment of the present invention so that the air flowing into the air passage 300 forms an upward airflow stably. can

The airflow forming unit 160 may be provided with a fan generating wind at the lower end of the air passage 300 of the furnace unit 100 to generate wind in an upward direction so that an upward airflow may be generated.

That is, an upward airflow may be continuously generated inside the air passage 300 through the airflow forming unit 160 , and due to the difference in air pressure formed by the airflow forming unit 160 , the inside of the furnace unit 100 . It can be induced so that the air is introduced into the air passage 300 through the lower air passage hole (120).

At this time, the airflow forming unit 160 may be driven by providing a power supply device including a dry cell, a USB type auxiliary battery, etc., but the method of supplying power is not limited to any one method, and various power supply methods are available. It is possible to configure by applying the method.

In addition, it is possible to separately configure a protective casing (not shown) for protecting the airflow forming part 160 formed at the lower end of the air passage 300 , and the lower end of the air passage 300 . It may be provided as the bottom surface of the outer housing 200 instead of this, and may be formed to be attached and detached as needed.

In the campfire wood 1, in the state in which the fuel is burned before the air inside the combustion chamber 110 is sufficiently heated, the airflow of the internal air is not clearly formed, so that the smoke generated while burning the fuel does not move to the flue 220. Otherwise, there is a possibility that it may leak through an external hole, and there is a possibility that the fuel may not be burned properly because the supply of oxygen is not smooth due to stagnant air.

Therefore, in the initial stage of using the firewood for camping (1), the combustion chamber (110) smoke inside the combustion chamber (110) by heating the chimney 220 using the circulating heating unit 221 to induce the flow of air in the chimney 220 direction. can be induced to pass through.

That is, when the flue 220 is heated by the circulation heating unit 221 and the air temperature inside the flue rises, the air out of the flue rises so that the air inside the firewood 1 for camping is directed toward the flue 220. It is formed so as to be able to quickly supply air containing oxygen at the initial stage of use of the firewood for camping ( 1 ), and to prevent smoke such as soot from leaking from places other than the flue ( 220 ).

As described above, the present invention has been described with reference to the embodiment shown in the drawings, but it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. will be.
