Description

Reverse Combustion Firewood Stove

The present invention relates to a wood stove, and more particularly, to a wood stove that burns upside down, which can delay heat and prevent backflow of smoke.

In general, a wood stove is a method in which air is introduced through an air passage formed at the lower end of the stove body, and solid fuel is burned in the stove body. This type of wood stove has a problem in that a lot of smoke and soot are generated because the solid fuel on the upper part of the solid fuel in the stove body does not burn well.

A wood stove that burns upside down is proposed to solve the problem of the wood stove. A firewood stove that burns upside down is characterized in that the passage of air introduced into the hearth body is formed at the upper end of the stove body.

Korean Patent Registration No. 1587377, which is a prior art of a firewood stove burning upside down, has the advantage of being able to ignite quickly to form an updraft and easy to clean the ash and soot remaining after combustion in order to solve the problems of the prior art. There are insufficient points to prevent the backflow of smoke and soot or to keep the heat inside the stove for a long time.
