The main body 2 is provided with a smoke absorbing hole 23 and a smoke exhaust hole 24 on a bottom plate constituting the lower surface.

The oven body 3 is composed of an oven portion 31 and a flue 32, and the flue 32 is spatially connected to the combustion chamber 28 by a smoke suction hole 23 and a smoke exhaust hole 24. The oven portion 31 is a space formed in a rectangular parallelepiped shape by an upper surface and a lower surface and four side surfaces including the front surface and the back surface, and the upper surface is in contact with the combustion chamber 28 via the bottom plate of the main body portion 2. Further, the oven portion 31 is in contact with the flue 32 on the lower surface and the side surface.

By covering the periphery of the oven unit 31 except the front surface with the combustion chamber 28 and the flue 32, heat is supplied to the oven unit 31 from multiple directions. In the present embodiment, the back surface of the oven unit 31 faces the outside instead of the flue 32, but the smoke can pass through the back side of the oven unit 31 so that smoke can pass through the flue 32 on all surfaces other than the front surface. May be placed.

Further, the oven main body 3 is provided with a lid portion 33 that closes the front surface, and the lid portion 33 can be arbitrarily removed. Therefore, when cooking using the oven unit 31, the user can put on and take off the lid unit 33 to put in and take out foodstuffs and the like.
