Description

一种斜流风机
技术领域
本实用新型属于风机技术领域，尤其涉及一种高效斜流风机，应用于各种通风装置、设备及系统。
背景技术
根据扇叶与轴向倾角的大小，风机可分为轴流、斜流（也称作混流）和涡轮风机，斜流风机因兼具较大风量及风压，且具有良好的线性和较宽的调速范围，因而被广泛应用于有一定风阻负载的通风装置、设备及系统。一般的斜流风机只是简单地将扇叶分布于圆柱形电机外壳/罩，外壳通常也为圆柱形，进出风口直径相同，没有前、后导风结构，扇叶前进风至后出风端气流速度有较大变化甚至突变，扇叶两面具有较大压差，从而造成紊流及噪声，并且出风气流成螺旋状，造成气流与出风后部件的摩擦阻力增加，降低了能效，风压通常也在200pa以下，致使其应用受到一定限制。
发明内容
本实用新型提供了一种斜流风机，旨在至少在一定程度上解决现有技术中的上述技术问题之一。
本实用新型是这样实现的，一种斜流风机，包括扇叶/体、导风罩、定向导风叶和外壳，所述扇叶/体和 定向导风叶 之间通过中心的轴承连接，固定在 圆锥形扇叶/体 中心的轴承穿过 定向导风叶 中心的预留孔并固定，所述导风罩通过卡点的作用直接卡住在外壳上的相应位置，所述定向导风叶与外壳通过 螺丝固定。
本实用新型实施例采取的技术方案还包括：所述扇叶/体为圆锥形。
本实用新型实施例采取的技术方案还包括：所述圆锥形扇叶/体的锥度A在50°至60°之间。
本实用新型实施例采取的技术方案还包括：所述圆锥形扇叶与轴向倾角B1为大于45°至B2为小于65°之间。
本实用新型实施例采取的技术方案还包括：所述圆扇叶数量为奇数。
本实用新型实施例采取的技术方案还包括：所述导风罩为喇叭口锥形，所述导风罩靠近扇叶/体，所述导风罩锥度D比扇叶锥度小6°至8°。
本实用新型实施例采取的技术方案还包括：所述导风叶起始弧段切线与轴向倾角E约为45°。
本实用新型实施例采取的技术方案还包括：所述定向导风叶数量为偶数，仅比扇叶数量多一片。
本实用新型实施例采取的技术方案还包括：所述外壳为圆柱形外壳。
相对于现有技术，本实用新型实施例所产生的有益效果在于：本实用新型的斜流风机，采用圆锥形扇叶/体及电机外壳/罩，锥度在50°至60°之间，并在扇叶前端至送风整个部分采用圆锥形导风罩，其锥度比扇叶锥度小6°至8°，使两扇叶间送风截面积在整个过程中适量逐渐变小（空气在压缩后体积缩小），以使气流在改变流向时保持流速尽可能一致，从而在扇叶前后两端产生“虹吸效应”，并使扇叶两面的压差最小，最大限度地减小了驱动阻力 ，同时，进一步在扇叶出风端采用定向导风叶，将螺旋形气流导流至轴向直流，减少气流与出风后部件的摩擦阻力，成倍地提高了风机的风压和能效，并有效降低了噪声。

图2为本实用新型实施例的斜流风机的剖面示意图；
图3为本实用新型实施例的斜流风机的正视图。
具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本实用新型，并不用于限定本实用新型。
请参阅图1至图3，图1为本实用新型实施例的斜流风机的组装示意图；图2为本实用新型实施例的斜流风机的剖面示意图；图3为本实用新型实施例的斜流风机的正视图。本实用新型实施例的斜流风机包括扇叶/体1、导风罩2、定向导风叶3和外壳4。扇叶/体1为圆锥形，也可以为其他形状。扇叶/体1和 定向导风叶3 之间通过中心的轴承（图未示）连接。固定在 圆锥形扇叶/体 中心1的轴承，穿过 定向导风叶3 中心的预留孔并固定。导风罩2通过卡点的作用直接卡住在外壳4上的相应位置。定向导风叶3 与外壳4的连接方式是用螺丝固定，也可以通过其他方式固定。
圆锥形扇叶/体1的锥度A在50°至60°之间，圆锥形扇叶与轴向倾角B1为大于45°至B2为小于65°之间，即圆锥形扇叶切风角度C2为大于25°至C1为小于45°之间，圆锥形扇叶数量为奇数 。
导风罩2为喇叭口锥形，导风罩2尽可能靠近圆锥形扇叶/体1，其锥度D比扇叶锥度小6°至8°，以使两扇叶间送风截面积在整个过程中适量逐渐变小（空气在压缩后体积缩小），以使气流在改变流向时保持流速尽可能一致，从而在扇叶前后两端产生“虹吸效应”，并使扇叶两面的压差最小，最大限度地减小了驱动阻力，并成倍地提高了风压，可达500-700pa，甚至以上。
定向导风叶3使螺旋形出风气流导流为轴向直流，减小了气流与出风后部件的摩擦阻力。定向导风叶3设计要点：导风叶3起始弧段切线与轴向倾角E约为45°，数量为偶数，仅比扇叶数量多一片，在有效导风的同时最大限度地减小导风阻力。
外壳4为圆柱形外壳，可以理解，外壳4也可以为其他形状。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
