Fig. 4 is a front view of the present invention, in which combustion preventing rings 40 and 41 are formed in the air inlet ports 20 and 21, respectively.

Fig. 5 is a cross-sectional view of the present invention and an enlarged cross-sectional view of a combustion preventing ring. Fig. 5 is a cross-sectional view of the combustion preventing ring of the present invention. And the lower concave groove 33 is shown.

6 is a cross-sectional view of a log burner having an exhaust port 32 according to another embodiment of the present invention.

As shown in the above figure, the air intake port 20 of the present invention is formed in a plurality of, and is installed at an appropriate height according to the length of the log, so that the air is supplied uniformly up and down. So that the amount of air can be adjusted, and the thermal power and the combustion time can be adjusted.

In other words, when a strong firepower is needed for cooking, a large amount of air is injected by opening the entire air intake port, and normally only one or two firepower can be controlled by opening the air intake port.

The number of the air intake openings 20 is preferably two to six, and the air intake openings 20 can be additionally installed depending on the thickness and length of the logs, and the diameter of the air intake openings 20 can be adjusted within a normal range.

The combustion preventing ring 40 is installed at the inlet of the air intake port to prevent the air intake port 20 from being burnt earlier than the combustion port 30 side during combustion of the log to prevent the log from being burned evenly. And is formed to have a length of 1/4 to 1/10. If it is shorter than the above range, the combustion preventing effect is deteriorated, and if it is longer, it interferes with the log burning.

Further, the combustion auxiliary port 31 functions to increase the initial combustion amount by widening the combustion area to increase the initial firepower, and the combustion auxiliary port 31 is formed with a plurality of, preferably 2 to 8, downward inclines around the combustion port according to the thickness of the log.

The exhaust port 32 is used as a passage through which a flame or smoke is discharged when the cooking container is placed in a log burner when cooked, and the cooking container can be directly placed on a log burner without using any other tool.

The structure of the exhaust port is connected to the combustion auxiliary port and made up of continuous grooves to the outside of the logs.

The recessed groove (33) is formed at a lower end of the combustion port lower than the air inlet (20).

The concave groove is provided to contain burning material such as paraffin for igniting the initial log. The combustion material falls and is deposited on the burning material. This concave groove is formed by the air intake port It is to act to prevent.

Hereinafter, the configuration and operation effects of the present invention will be described with reference to the most preferred embodiments of the present invention.

First, a circular combustion hole 30 is formed in the log from the upper center to the lower end of the log. Normally, the diameter of the combustion hole is in the range of 10 to 25% of the log diameter. Outside of this range, the burning time is delayed or accelerated and the effect as a log burner is reduced.

And the depth of the combustion port is formed to a depth of 80 to 95% of the log length.

Since the combustion of the logs is usually carried out in the upper part, it is preferable that the thickness of the lower part is made as thin as possible within the above range.

The combustion auxiliary port 31 is formed in a cruciform shape downwardly after the combustion port 30 is formed and the air inlet port 20 is formed on the combustion recess bottom recessed groove 33 and a plurality (21, 22, etc.) of the air intake port and the combustion preventing ring (40) is formed in the air intake port.

In the present embodiment, four air inlets are provided (see FIGS. 20, 21 and 23, see FIG. 5, and the remaining air inlets are not shown).

An exhaust port 32 communicating with the combustion auxiliary port 31 is formed to be connected to the outside of the log.

The operation of the log burner having the above structure will be described.

First, the concave groove 33 of the log burner is filled with a combustion material such as paraffin, and a core (not shown) immersed with paraffin is extended to the outside of the lowermost air inlet 20.

(Not shown) of the concave groove 33 along the wick when the wick is burned to ignite the log burner, and the fire is transferred to the log by the burning port 30 in the log by the firebox The fire is spreading in the upper part while sticking. At this time, more air is supplied from the zigzag air inlet (21, 22, etc.) formed at the upper part to complete combustion, and a combustion initializing force is obtained by widening the combustion area by the combustion auxiliary port (31).

It takes about 10 to 20 minutes to generate a strong initial firepower of the present invention, but it took about one hour for a conventional log burner and about 30 minutes for an air supply means such as a hose.

Also, after the cooking is finished, the part of the air intake port is closed to lower the firearm, so that the firepower can be adjusted and the burning time can be extended.

The air intake port 20 is provided with a combustion preventing ring 40 to prevent combustion of the air intake port by backfire so that the combustion of logs is made constant.

The conventional log burner has no combustion preventing ring 40, and the air intake port and the combustion port are simultaneously combusted due to the backflow, so that the logs can not be uniformly combusted.

Further, since the cooking vessel can be placed directly on the log burner by forming the exhaust port 32, an auxiliary tool is not required. However, the conventional log burner has the disadvantage of separately preparing a mounting tool on the upper part, have.

As described above, the present invention solves the problems of the conventional log burner and greatly improves the effects thereof.
