    • The object is to provide a burner capable of taking in sufficient primary air even though the size thereof is compact, and capable of being used as an all-primary air burner. A burner includes a mixing pipe to which a fuel gas and combustion air are supplied, a burner main body having a mixing chamber at a top end on a downstream side of the mixing pipe, and a burner head which is provided at an upper part of the burner main body while communicating with the mixing chamber and has first and second burner ports for ejecting mixed gas of the fuel gas and air for combustion mixed in the mixing chamber. The burner further includes an extension pipe in the burner main body protruding inside the mixing chamber being formed by extending the mixing pipe.
    • 本发明的目的是提供一种能够承受足够一次空气的燃烧器,即使其尺寸紧凑,并且能够用作全一次空气燃烧器。 燃烧器包括供给燃料气体和燃烧空气的混合管,在混合管的下游侧的顶端具有混合室的燃烧器主体和设置在混合管的上部的燃烧器头部 该燃烧器主体与混合室连通并具有第一和第二燃烧器端口,用于喷射混合在混合室中的燃料气体和燃烧空气的混合气体。 燃烧器还包括在燃烧器主体中的延伸管,其通过使混合管延伸而在混合室内突出。

    • To provide a water heater capable of suppressing an increase of combustion air temperature and suppressing to generate nitrogen oxide with an easy structure. In a water heater, a burner provided in a combustion chamber provided below a hot water storage chamber is an all primary air burner taking in air required for combustion, where the air is mostly primary air. Further, the burner is provided with a supporting plate in the combustion chamber at the height that a part of a burner head is protruded into a space covered by a lower mirror plate.
    • 提供能够抑制燃烧空气温度升高并且以容易的结构抑制产生氮氧化物的热水器。 在热水器中,设置在设置在热水储存室下方的燃烧室中的燃烧器是全部一次空气燃烧器,其接收燃烧所需的空气,其中空气主要是初级空气。 此外,燃烧器在燃烧室中设置有支撑板,该支撑板在燃烧器头部的一部分突出到由下镜板覆盖的空间中的高度处。
