Description

A combined fully enclosed smoke and dust removal energy-saving wood stove

Technical Field

The invention relates to a solid fuel stove, in particular to a combined fully enclosed smoke and dust removal energy-saving firewood stove.

Background technique

A wood stove is a cooking utensil that uses firewood as fuel. Existing wood stoves have made many improvements on the traditional earth stove structure. For example, the publication number CN207539937U discloses a combined multi-oxygen adjustable low-smoke wood stove, which includes a stove table and a stove body located below the stove table. The stove body is characterized in that an oxygen supply box is provided below the stove body, a furnace is provided inside the stove body, and the bottom of the furnace is an inner tank arranged in the oxygen supply box. The inner tank has a firewood storage space, a grate is provided at the bottom of the inner tank, and an ash storage drawer is provided below the grate; a flame oxygenation hole is provided on the upper apron of the inner tank; an outer cover is provided outside the inner tank, and a sealing sliding plate is provided at the bottom of the outer cover; an adjustable air door is provided on the oxygen supply box; and a detachable water-cooled chimney is provided at the edge of the stove table. The improvement focus of this patent is to increase oxygen when firewood is burned, which can both fully burn and save energy. However, this wood stove needs to control the size of the damper when igniting, and ignition is precisely the most difficult step of the wood stove. If the damper is too large, the initial flame is easily blown out by the airflow; if the damper is too small, the initial flame is easily extinguished due to lack of oxygen. Therefore, this wood stove has high requirements for ignition and is not easy to operate. At the same time, the air intake direction of this wood stove is located in the side direction of the combustion part, and the grate is fixed, so the ash will be blocked. As the combustion proceeds, the ash will accumulate more and more due to the decrease in falling efficiency, resulting in poor airflow in the center of the combustion part. The lateral air intake cannot improve this situation, and the accumulated ash will also affect the carbon output operation. Finally, although the chimney of the wood stove is detachable, the volume of the stove body plus the oxygen supplement box is still large, which is not conducive to transportation. Therefore, designing a wood stove that is easy to ignite, has higher efficiency in oxygenation and ash and carbon output, and is easy to transport is a problem that technicians in this field urgently need to solve.
