Summary: | To provide a combustion device which is furnished with a combustion chamber 2 and an air feed chamber 3 on its lower side in a combustion box 1, and in which air fed from a fan 6 to the air feed chamber 3 is fed to each burner 5 in the combustion chamber 2 as primary air, and fed to the combustion chamber 2 as secondary air via distributed holes 41 formed through a partition plate 4 of an upper surface of the air feed chamber 3, and which facilitates the flow of air also to the distributed holes formed in a part of the partition plate 4 near an air inlet 34, in an article in which the air inlet 34 for flowing air from the fan 6 into the air feed chamber 3 is opened in at least one wall surface of a back side surface 32 and one side wall surface in a lateral direction of the air feed chamber 3.SOLUTION: An air feed chamber 3 is furnished with a screen plate 35 facing an air inlet 34 and repelling a part of air flowing in from the air inlet 34 toward the air inlet 34 side, and is furnished with an eave part 36 projecting from an upper edge of at least a part of the air inlet 34 toward the inside of the air feed chamber 3.SELECTED DRAWING: Figure 4
【課題】燃焼筐1内に、燃焼室2とその下側の給気室3とが設けられ、給気室3にファン6から供給された空気が、燃焼室2内の各バーナ5に一次空気として供給されると共に、給気室3の上面の仕切板4に形成した分布孔41を介して燃焼室2に二次空気として供給されるようにした燃焼装置であって、ファン6からの空気を給気室3に流入させる空気流入口34が給気室3の後壁面32と横方向一方の側壁面との少なくとも一方の壁面に開設されるものにおいて、空気流入口34に近い仕切板4の部分に形成した分布孔にも空気が流れやすくする。【解決手段】給気室3に、空気流入口34に対向して、空気流入口34から流入した空気の一部を空気流入口34側に跳ね返す衝立板35を設ける。また、空気流入口34の少なくとも一部分の上縁から給気室3の内方に張り出す庇部36を設ける。【選択図】図4 |
