如图1和图2所示,本申请一实施例中的一种出风格栅10,包括:出风本体100,出风本体100设有出风端;及筋条,筋条设置于出风端,且筋条相对出风本体100的轴向倾斜设置,筋条的倾斜方向与风机的旋转方向相同,筋条呈弧形状,筋条沿靠近出风本体100中心的端部至筋条远离出风本体100中心的端部方向弯曲,且筋条的弯曲方向与风机的旋转方向相反。
上述出风格栅10在使用时,驱动风机旋转,风呈螺旋式向外移动,风速包括轴向的 速度分量、径向的速度分量和周向的速度分量,由于筋条相对出风本体100的轴向倾斜设置,如图1所示,箭头指示的方向为风机的旋转方向,如图2所示,箭头指示的方向为风的螺旋方向,筋条的倾斜方向与风机的旋转方向相同,如此,可以降低风在周向上的损耗,风可以顺着筋条的倾斜方向排出;进一步,筋条呈弧形状,筋条沿靠近出风本体100中心的端部至筋条远离出风本体100中心的端部方向弯曲,且筋条的弯曲方向与风机的旋转方向相反,如此,可以实现送风集中,进而提升送风距离。
如图1和图2所示,在上述实施例的基础上,筋条包括凸设的外壁312,外壁312与出风本体100的轴线的夹角沿出风本体100的中心至出风本体100的外壁312的方向逐渐增大。如此,因为上升的螺旋气流在不同半径上速度矢量的倾斜角度不同,半径越大处气流倾斜角度越大,为了顺应气流,减小能量损失,外壁312与出风本体100的轴线的夹角从内向外慢慢变大,进而,避免了外壁312与出风本体100的轴线的夹角从内到外一致导致外壁312与出风本体100的轴线的夹角在出风格栅10的内圈夹角过大,对上升气流造成阻挡,增加损耗且增加了出模的难度。在该实施例的基础上,筋条包括相对的第一端和第二端314,第一端靠近出风本体100中心设置,第二端314远离出风本体100中心设置,位于第二端314的外壁312与出风本体100的轴线的夹角为15°至40°。如此,如图2所示,位于第二端314的外壁312与出风本体100的轴线的夹角为α,当15°≤α≤40°时,风的损耗低,送风距离较大;当α<15°时,风在周向的损耗较大,降低送风距离;当α>40°时,出风阻力大,风在轴向的损耗较大,降低送风距离。在上述实施例的基础上,位于第二端314的外壁312与出风本体100的轴线的夹角为30°≤α≤40°。如此,位于第二端314的外壁312与出风本体100的轴线的夹角在该范围内时,风的损耗最低,送风距离最大。
如图1和图2所示,在上述任一实施例的基础上,筋条包括第一筋条210、第二筋条310、环形加强筋400及控制件500,出风本体100包括风道,第一筋条210的一端为第一端、并与控制件500连接,另一端与环形加强筋400连接,第二筋条310的一端与环形加强筋400连接、第二筋条310的另一端为第二端314、并与风道的内壁连接,第一筋条210的弯曲方向和第二筋条的弯曲方向相同。如此,通过设置第一筋条210和第二筋条310代替一个筋条,并将第一筋条210和第二筋条310设置于环形加强筋400上,可以提升出风格栅10的强度,在本次实施例中,控制件500为控制面板,控制面板设置于出风本体100的中部位置,第一筋条210和第二筋条310沿控制面板向外发散设置。
如图1所示,进一步,在上述任一实施例的基础上,第一筋条210的数量为多个,所有第一筋条210沿第一圆周间隔设置,第二筋条310的数量为多个,所有第二筋条310的 沿第二圆周间隔设置,且第一筋条210的数量小于第二筋条310的数量。由于,出风本体100的半径最大处,风速越高,因此为了使气流分布均匀,将第一筋条210的数量减少,使第一筋条210的数量少于第二筋条310的数量,进而,降低位于第一筋条210处的风阻,而位于第二筋条310处的风速也会降低,如此可以提升风量,同时可以降低气流噪声。
如图1所示,在上述任一实施例的基础上,相邻两个第一筋条210和第二筋条310交错设置。如此,可以提升整个出风格栅10的美感。在该实施例的基础上,相邻两个第一筋条210之间的夹角大于相邻两个第一筋条210和第二筋条310之间的夹角。如此,可以降低风流在内圈的风阻,如此,可以提升送风距离。
在上述任一实施例的基础上,第一筋条210的弦长长度等于第二筋条310的弦长长度。如此,由于第一筋条210和第二筋条310呈弧形,当第一筋条210的弦长长度等于第二筋条310的弦长长度时,第一筋条210和第二筋条310的强度接近相等,避免第一筋条210或第二筋条310因为强度过低,影响整个出风格栅10的整体强度。
另一方面,本申请还涉及一种空气净化器,包括出风格栅10。
上述空气净化器在使用时,驱动风机旋转,风呈螺旋式向外移动,风速包括轴向的速度分量、径向的速度分量及周向的速度分量,由于筋条相对出风本体100的轴向倾斜设置,如图1所示,箭头指示的方向为风机的旋转方向,如图2所示,箭头指示的方向为风的螺旋方向,筋条的倾斜方向与风机的旋转方向相同,如此,可以降低风在周向上的损耗,风可以顺着筋条的倾斜方向排出;进一步,筋条呈弧形状,筋条沿靠近出风本体100中心的端部至筋条远离出风本体100中心的端部方向弯曲,且筋条的弯曲方向与风机的旋转方向相反,如此,可以实现送风集中,进而提升送风距离。
以上实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
