Abstract
In an infrared stove apparatus, there is provided a stove body having a radiation window at the front and upper portions of the stove body. A frame is placed within the stove, and one open end of the frame faces to the front portion of the stove body so as to serve as a radiation opening, the other open end of the frame having a porous burner plate through which a mixture of fuel gas and air is to be released. An exhaust opening is provided at the upper lateral side of the frame to pass exhaust gas released through the porous burner plate when the mixture of fuel gas and air is ignited at the time of operation. A metallic net of a suitable mesh screen is provided within the exhaust opening to increase fluid-resistance of the exhaust gas flowing out through the exhaust opening so as to keep a uniform velocity distribution of the exhaust gas while restraining outside air from entering into the frame through the radiation opening leading to the exhaust opening.
