Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of stove structures, and in particular relates to a multifunctional stove for use with both firewood and coal. Background Art
[0002] Stoves are widely used in rural areas and outdoors. They are commonly used tools for heating and cooking. Traditional stoves are usually composed of a stove body, a combustion chamber, an ash box and a chimney. Fuel burns in the combustion chamber to release heat for heating or cooking. However, traditional stoves are usually single-layer structures, which dissipate heat quickly and consume fuel quickly. If you want to increase the firepower, you need to add a lot of fuel, resulting in fuel waste. In addition, traditional stoves have less functionality and do not have a special baking space, so they cannot bake food. Traditional smoke exhaust pipes are usually made of single-layer iron sheets or red bricks. Smoke exhaust pipes made of single-layer iron sheets have severe heat dissipation and high surface temperature, which are prone to scalding accidents. In order to avoid scalding, some smoke exhaust pipes are made into double-layer structures, which can effectively reduce the temperature of the smoke pipe surface and avoid scalding. However, the existing exhaust pipe shell and the internal smoke pipe are usually connected by welding, so it is necessary to add insulation material between the shell and the internal smoke pipe to prevent the outer shell from getting hot. In addition, the welding process is cumbersome, the material consumption is high, and the production cost is high. Summary of the invention
[0003] The purpose of the present invention is to provide a multifunctional stove for burning coal and firewood. A detachable furnace core is arranged in the furnace body, which can burn coal or firewood, reduce coal consumption and improve firepower. The chimney of the furnace body is arranged as a double-layer structure to prevent burns.
