Description

浴室用取暖换气扇 领域技术
本发明是关于一种换气扇， 尤其是关于一种浴室用取暖换气扇。 背景技术
如图 1所示， 为一种公知的浴室用取暖换气扇 100， 包括： 框架 110、 装有扇叶 120的马达 130、 罩住马达 130的蜗牛壳 140、加热装置（图中未示）、风路切换板 160 以及控制电路机构 Π0等， 其通过风路切换板 160的转动来实现取暖换气扇 100的取 暖、 换气、 和干燥功能。
如图所示， 通常情况下， 框架 110设置成长方形， 也就是说换气扇 100以从室内 空气进风口到室内暖风出风口 180的方向为长方向设置。并且设有室内暖风出风口 180 和向屋外排出空气的排气出风口 181这两个出风口。
为实现向两个出风口排气， 在装有扇叶 120的马达 130的出风口 131处利用风路 切换板 160切换风路。 而且在室内暖风出风口 180侧的风路处设加热装置。
如图 2所示， 为另一种类的公知的利用红外线灯泡发射红外辐射来实现取暖的浴 室用取暖设备 190， 这一类取暖设备不具循环空气功能。 这些取暖设备， 在正方形的 本体上向下排列 4个灯泡。 与上述利用设置送风机循环空气的浴室用取暖换气扇 100 相比， 浴室用取暖设备 190显得较小巧。
因此， 为把具向浴室循环空气功能的浴室用取暖换气扇 100安装在以上述浴室用 取暖设备 190为前提设计的浴室内， 框架 110要设成和浴室用取暖设备 190同样的形 状。 发明内容
本发明为解决上述问题， 特提供一种即使缩短室内空气进风口至室内暖风出风口 之间距离也能顺畅地吹出暖风， 热效率高的浴室用取暖换气扇。
为实现上述目的， 本发明提供一种浴室用取暖换气扇， 包括： 框架、 装有扇叶的 马达、 蜗牛壳、 设于蜗牛壳的出风口处、 切换换气扇本体出风口的风路切换板以及加 热装置、 使上述带扇叶的马达和风路切换板和加热装置运行的控制电路机构， 其特征 在于， 在换气扇本体的高度方向上分开、 重叠地设置风路切换板和加热装置， 扇叶中 心和蜗牛壳舌部偏离本体的中心线并位于同一侧， 并且本体的中心线、 风路切换板的 中心线、 加热装置的中心线成水平一致设置并重叠。
所述的浴室用取暖换气扇， 蜗牛壳舌部弯角的角度小于或等于 30度以内。
所述的浴室用取暖换气扇， 风路切换板风道长方向上的长度和加热装置长方向上 的长度相等。 '
所述的浴室用取暖换气扇， 控制电路机构设置在反舌部侧的风路外侧侧面部。 附图说明
图 1是一种公知浴室用取暖换气扇的示意图；
图 2是另一种公知浴室用取暖换气扇的示意图；
图 3是本发明的浴室用取暖换气扇的整体剖视示意图；
图 4是本发明的加热装置和风路切换板位置示意图。 具体实施方式
如图 3所示， 本发明的浴室用取暖换气扇的整体剖视 ¾^意图。 该图为平视产品 时示意图。
浴室用取暖换气扇 200， 包括： 框架 210、 装有扇叶 220的马达 230、 罩住马达' 230的蜗牛壳 240、设于蜗牛壳 240的出风口 243处切换本体出风口的风路切换板 260 以及设于由上述风路切换板 260切换的其中一个方向的风路的加热装置 250、 使上述 马达 230和风路切换版 260和加热装置 250运行的控制电路机构 270。
如图 4所示， 是本发明的加热装置和风路切换板位置示意图。 风路切换板 260 和加热装置 250在本体的高度方向上分开、 重叠设置。
再请参看图 3，扇叶中心 300和蜗牛壳 240的舌部 241偏离本体的中心线 400并 位于同一侧设置， 并且本体的中心线 400、 风路切换板 260的中心线、 加热装置 250 的中心线成水平一致设置并重叠。 所述的本体的中心线 400是指框架 210本体外轮廓 的中心线。
由于扇叶中心 300和蜗牛壳舌部 241偏离本体的中心线 400并位于同一侧设置， 所以舌部 241到蜗牛壳 240出风口 243的顶部 242之间的距离 L1可以设计得更加长， 舌部 241末端 244到风路切换板 260端部 261之间的的距离 L3可设置得更短， 也就 是说将风路切换板 260和蜗牛壳 240的出风口 243相对应的话， 风路切换板 260对应 上述 LI的长度占得比例大， 相反， 风路切换板 260除了对应 L1的长度后， 剩下的长 度 L2占得比例就小， 起到加大蜗牛壳 240的出风口 243和风路切换板 260， 并使舌部 241下侧区域的风量与上侧区域的风量平均化的作用；
再由于本体的中心线 400、 风路切换板 260的中心线、 加热装置 250的中心线成 水平一致并重叠，所以风路切换板 260和加热装置 250可以位于框架 210本体的中心， 也就是说， 风路切换板 260和加热装置 250可以以框架 210本体的中心向两端最大限 度地扩展。 而且， 风路切换板 260和加热装置 250共同形成的从本体中心向两端延长 的断面为长方形的风道中， 风路切换板 260的风道长方向上的长度和加热装置 250长 方向上的长度相等， 所以从蜗牛壳 240的出风口 243出来的风经过风路切换板 260的 风道后， 没有被压缩或扩大地直接通过加热装置， 起到风速均一的作用； 通过以上的 构造， 还可以将框架 210设置成大致正方形的产品， 框架 210的出风口的接头 246设 置在框架 210外侧的中心， 这样的话， 就可以把框架 210设成正方形， 即使是以先有 技术的浴室用取暖换气扇 100为前提设计的浴室也可以很容易安装。 还可以根据实际 施工的现场的需要， 分别 90度地转动正方形框架， 实现四个方向也可以排气施工。 因此， 虽然缩短了室内空气进风口至室内暖风出风口之间距离也能保持风路平滑， 确 保热效率。
蜗牛壳 240的舌部 241弯角 β的角度小于或等于 30度以内， 如图 3所示。 所述 的舌部 241弯角 β是指在平视产品时， 舌部风路壁与风路切换板 260的端部 261之间 的风路壁，和本体垂直的纵向直线 245之间的夹角。通过以上的构造，使得蜗牛壳 240 的出风口 243离扇叶中心 300的距离变小， 起到充分利用框架 210内空间的作用， 并 使整个产品的结构更加小型化， 方便安装。 提高产品的安装性。
控制电路机构 270设置在反舌部侧的风路外侧侧面部。所谓的舌部侧和反舌部侧， 是指扇叶 220的横向中心线 310把换气扇本体分为两部分， 设有舌部 241的一侧为舌 部侧 311， 不设舌部 241 的一侧为反舌部侧 312。 通过以上的构造， 将控制电路机构 270和风路切换板 260成 L字形的方位设置于反舌部侧 312的风路外侧侧面部， 这样 的话， 风路切换板 260的安装位置可以利用蜗牛壳 240的舌部 241下侧的空间， 使风 路切换板 260和加热装置 250安装的位置一致。 并且， 控制电路机构 270侧可设加热 装置 250的引线伸出部和风路切换板 260控制电机、 无线信号接收器等的作动装置， 通过在控制电路机构 270侧设作动装置使引线变短从而节省成本， 方便组装， 而且使 整个产品的结构更加小型化， 方便安装。
