Patent ID: 8220449

Claim:
A portable stove comprising: a base provided with a diffusion chamber and an air channel having an outlet in fluid connection with the diffusion chamber and an inlet wherein the air channel includes a volute integrally mounted to the base; a diffuser plate mounted to the diffusion chamber; the diffuser plate defining a biomass support and being provided with at least one aperture; an air flow generator mounted in the volute and being so associated with the inlet of the air channel as to positively pressurize the diffusion chamber with air, wherein the air flow generator includes an electric motor and a fan associated with a rotatable shaft of the electric motor; and a Peltier cell in heat transfer relationship with the diffuser plate and coupled to power the electric motor; wherein the diffuser plate is made of a heat conductive material and includes an integral extension; one of the opposite faces of the Peltier cell being positioned adjacent the integral extension; whereby the one of the opposite faces is heated by the integral extension; whereby the air positively pressurizing the diffusion chamber exhausts through the at least one aperture of the diffuser plate to thereby oxygenate the combustion of the biomass.
