摘要

[Abstract] To prevent the plaques baked [PROBLEMS] the baked product is to provide a gas oven to form a wide space for accumulation heat of the combustion gases at the top of the baking chamber. A gas oven fixed A1 A reference numeral 1 is equipped with a firing chamber 11 for accommodating an object to be fired product 2 of dough, etc.. On fire burners 3a is disposed on the upper side of the baking chamber 11, a gas burner 3 for burning down the lower side of the baking chamber 11 b is disposed. On the back side of the baking chamber 11, the firing chamber 1 the combustion gas in the gas fuel is combusted in a burner flame above 3a Outlet 4a is provided with a plurality of upper for discharging out of the 1, the discharge port 4a is positioned lower than the flame hole on the fire burners 3a on.
