The outdoor air inflow type brazier according to the present invention configured as described above is used as follows.

First, the combustion material is introduced into the opening hole 301 of the upper plate 300 , and the combustion material is seated on the combustion plate 400 installed in the inner space S of the side panel part 100 .

And, when the combustion material provided in the combustion plate 400 is ignited by using a separate ignition tool (eg, lighter, match), the combustion material is ignited and a flame is generated in the inner space (S). occurs

At this time, when air is introduced into the inner space S through the air inlet hole 201 of the side panel part 100 and the lower plate 200 forming the inner space S, the air is supplied as a flame. As a result, the flame burns the combustible material while causing a combustion action, and is maintained in an ignited state.

In particular, the side panel part 100 is fixed in an upright state between the upper and lower plates 300 and 200, and is installed to overlap each other in an annular shape, and by forming an air channel 100a therebetween, the air channel ( Air around the side panel part 100 is supplied to the inner space S through 100a).
