本实用新型的目的在于提供一种风机,旨在解决现有技术中存在的风机应用于空气净化机中并不能根据空气净化机的不同档位来调整 t 值的大小以适应噪音与出风量的需求的问题。
技术解决方案
本实用新型是这样实现的, 一种风机,其包括罩壳、位于所述罩壳内的叶轮及驱动所述叶轮转动的电机,所述风机还包括围设于所述叶轮的外围且位于所述罩壳内的可相对于所述叶轮转动的导风装置,所述叶轮包括排布于同一第一圆上且沿第一时针方向旋转倾斜的若干叶片,所述导风装置包括排布于同一第二圆上且沿与所述第一时针方向相反的第二时针方向旋转倾斜的若干导风件,所述第二圆位于所述第一圆之外且所述第二圆与所述第一圆同心,所述若干导风件于相邻所述导风件之间形成若干出风口, 所述罩壳的外围对应于所述出风口开设有若干排风口,所述导风装置的所述导风件在所述叶轮的出风的推动下相对于所述叶轮转动。本实用新型的风机将导风装置限制于一罩壳内,且不需要蜗壳作为导风部件,而是将体积较大的蜗壳去除,采用体积较小的若干围设于叶轮外围的导风件,所有导风件之间形成若干出风口,通过若干出风口平均分配叶轮所带入的气流,然后通过这些出风口再由罩壳上的排风口均匀排出,风压减小,风速变得较适宜人体需要,通过若干导风件围设于叶轮的外围,在至少不增加风机的体积的前提下,增加了出风口的数量,提高了出风量,满足人们对空气净化的需求。

进一步地, 所述风机还包括安装板,所述叶轮的各个所述叶片的底端立于所述安装板上,所述叶轮的各个所述叶片的顶端固定连接有一固定板,所述电机的外壳固定安装于所述安装板的中部上,所述电机的输出轴转动连接于所述固定板的中部上。

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仅用以解释本实用新型,并不用于限定本实用新型。
请同时参阅图 2 和图 3 ,本实用新型实施例提供的 空气净化机 10 包括壳体 11 、设置于所述壳体 11 内的净化装置(图未示)及风机 13 ,所述风机 13 设置于所述壳体 11 的顶部 。

本实用新型的风机 13 设置于空气净化机 10 的壳体 11 的顶部,气流在壳体 11 内经过净化装置净化后再进入风机 13 内,再由风机 13 的多个出风口 20 排出,避免了现有技术中的风机 13 朝向净化装置吹风所带来的噪音大的问题。
本实用新型的风机 13 将导风装置 17 限制于一罩壳 14 内,且不需要蜗壳作为导风部件,而是将体积较大的蜗壳去除,采用体积较小的若干围设于叶轮 15 外围的导风件 19 ,所有导风件 19 之间形成若干出风口 20 ,通过若干出风口 20 平均分配叶轮 15 所带入的气流,然后通过这些出风口 20 再由罩壳 14 上的排风口 21 均匀排出,风压减小,风速变得较适宜人体需要,通过若干导风件 19 围设于叶轮 15 的外围,在至少不增加风机 13 的体积的前提下,增加了出风口 20 的数量,提高了出风量,满足人们对空气净化的需求。
请同时参阅图 4 和图 5 ,图 4 示出了气流的走向,图 5 示出了导风件 19 出风处的风速三角形,其中实线代表导风件 19 调整前的风速三角形,虚线代表导风件 19 调整后的风速三角形,在风速三角形中, B2 是指导风件 19 的出口角度,具体为,首先定义叶轮 15 的叶片 18 的出风端与该叶片 18 所在的圆的圆心的连线的垂直线为 A ;定义导风件 19 的出风端与该导风件 19 所在的圆的圆心的连线的垂直线为 B ,垂直线 A 与垂直线 B 之间的夹角即为 B2 ; W2 是净化机 10 的实际出风速度, W2 ' 是净化机 10 调整后的实际出风速度, C2r 为净化机的出风径向速度, C2r ' 是净化机 10 调整后的出风径向速度, U2 为净化机的出风轴向速度, U2 ' 为净化机 10 调整时补偿的出风轴向速度; W2 、 C2r 、 U2 三者组成调整前的风速三角形, W2 ' 、 C2r ' 、 U2-U2 ' 的差值组成调整后的风速三角形。
在本实用新型中,导风装置 17 的各个导风件 19 是可以相对于叶轮 15 转动的,当风机 13 的叶轮 15 的转速高于设计转速时,导风件 19 相对于叶轮 15 转动,对于由叶轮 15 的两个叶片 18 之间流出的一股气流来说,该股气流在导风件 19 相对于叶轮 15 固定不动时,本该直接由相邻导风件 19 之间排出,但由于导风件 19 转动,该股气流在相邻导风件 19 之间并由该导风件 19 带动着在导风件 19 之间产生一个减速效应,使得该股气流流过导风件 19 的时间增长,路程也变长,等同于背景技术中的 t 值的变大,相当于净化机 10 输入一个 U2 ' 的补偿值,形成调整后的风速三角形,由此达到降低气流噪音的目的;当风机 13 的叶轮 15 转速小于设计转速时,该股气流在导风件 19 之间流过的时间会缩短,路程变短,等同于 t 值减小,使出风量相应地增加,由此,当上述风机 13 应用于 空气净化器 10 等家电产品中 上时,对于不同的档位,由导风件 19 相对于叶轮 15 的转动来实现出风量和噪音的最佳组合。
所述导风装置 17 的各个所述导风件 19 根据所述叶轮 15 的转速而调整相对于对应的所述叶片 18 的转动位置。
所述导风装置 17 相对于所述叶轮 15 转动具有预定转动阻尼力,所述叶轮 15 的出风对所述导风装置 17 的所述导风件 19 具有一推动力,所述导风装置 17 的所述导风件 19 于所述推动力大于所述预定转动阻尼力时相对于所述叶轮 15 转动。
在这里, U2 ' 同 U2 成正比关系,满足上述的要求。只要适当的调整叶轮 15 的预定转动阻尼力,就能够调整出满足空气净化器等家电不同档位的出风量及噪音要求。
所述壳体 11 上开设有进风口(图未示),气流由该进风口进入壳体 11 内,并经过净化装置的净化后进入风机 13 内部,然后由风机 13 的若干个出风口 20 排出至室内。
所述壳体 11 对应所述风机 13 的底部开设有若干通风口(图未示),该通风口的存在,使经过净化装置净化后气流由该通风口进入风机 13 的叶轮 15 处。
请同时参阅图 6 ,所述风机 13 还包括安装板 31 ,所述叶轮 15 的各个所述叶片 18 的底端立于所述安装板 31 上,所述叶轮 15 的各个所述叶片 18 的顶端固定连接有一固定板 50 ,电机 16 的输出轴 161 穿过该安装板 31 与叶轮 15 安装,以驱动叶轮 15 的旋转。所述安装板 31 对应所述叶轮 15 开设有通口,使在电机 16 的驱动下,叶轮 15 的转动会将气流带入叶轮 15 内,然后由相邻导风件 19 之间形成的出风口 20 排出至室内。
具体地,所述电机 16 的外壳固定安装于所述安装板 31 的中部上,所述电机 16 的输出轴 161 转动连接于所述固定板 50 的中部上。

进一步地, 所述安装板 31 的中部开设有通口 32 ,所述安装板 31 于所述通口 32 的周围设置有若干固定孔 33 ,所述电机 16 的外壳凸设有若干固定部 160 ,所述电机 16 的上部穿过所述通口 32 ,所述固定部 160 与所述固定孔 33 对应固定。固定部 160 位于安装板 31 之下。
请同时参阅图 7 ,在本实施例中,所述空气净化机 10 所使用的叶轮 15 的尺寸参数如下:轮叶直径 D : 250mm ,进口直径 d : 200mm ,入口角 σ : 40 度,出口角 ρ : 50 度,轮叶高度 h : 80mm ,叶片 18 数量: 36 ,这里所说的轮叶高度是指叶片 18 的长度。对于轮叶直径 D 与进口直径 d 根据在相同罩壳 14 下所能够允许的尺寸进行设定,不一定如本实施例的尺寸参数。同样地,入口角 σ 和出口角 ρ 可以根据在风量要求进行设定,不一定如本实施例的尺寸参数。
请同时参阅图 8 和图 9 ,每一所述导风件 19 为呈片状的导风片,每一所述导风片具有入风端 41 及出风端 42 ,若干所述导风片的入风端 41 均位于同一第一圆线 43 上,若干所述导风片的出风端 42 均位于同一第二圆线 44 上。
进一步地,每一所述导风片的所述入风端 41 与该导风片所在的所述第一圆线 43 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角均相同,每一所述导风片的所述出风端 42 与该导风片所在的所述第二圆线 44 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角均相同。
进一步地,每一所述导风片的所述入风端 41 与该导风片所在的所述第一圆线 43 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角 ω 范围为 5-20 度,即导风片的入口角 ω 范围为 5-20 度;每一所述导风片的所述出风端 42 与该导风片所在的所述第二圆线 44 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角 φ 范围为 36-45 度,即导风片的出口角 φ 范围为 36-45 度。
优选地,每一所述导风片的所述入风端 41 与该导风片所在的所述第一圆线 43 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角 ω 为 10 度,即导风片的入口角 ω 为 10 度;每一所述导风片的所述出风端 42 与该导风片所在的所述第二圆线 44 的圆心之间的连线的垂直线及该导风片所在倾斜的方向之间所形成的锐角 φ 为 38 度,即导风片的出口角 φ 为 38 度。
在本实施例中,每一所述导风片所在的第一圆线 43 的直径为 270mm ,每一所述导风片所在的第二圆线 44 的直径为 340mm ,每一所述导风片的高度为 100mm ,这里所说的导风片的高度是指导风片的长度,所应用的导风片的数量为 15 。
可以理解地,导风片的具体排布的片数及尺寸可以根据罩壳 14 内所述能排布导风片的空间来决定。
在本实施例中,风机 13 的出风口 20 的数量多于四个,使叶轮 15 所带入的气流更加均匀地由出风口 20 排出,可以理解地,罩壳 14 的排风口 21 也分布于罩壳 14 的外围,以便于由出风口 20 排出的气流再由排风口 21 排到室内。
在本实用新型的风机 13 中,风机 13 采用导风件 19 的结构配合叶轮 15 来完成气流的分配,在本领域内,对于现有技术中存在的叶轮 15 与蜗壳的配合实现气流的分配,由于蜗壳的设计是有一定的设计规格的,对于同样的叶轮 15 来说,采用一个出风口的蜗壳会比本实用新型的风机 13 里所使用的导风件 19 所占的体积要大,因此,本实用新型的风机 13 采用导风件 19 的设计使整个风机 13 的体积减小,进而整个空气净化机 10 的体积也相应减小。
上述空气净化机 10 采用导风件 19 配合叶轮 15 实现多个出风口 20 的设计,使风机 13 的出风量增加,虽然,此时出风量增加或多可少都会减小出风口 20 的风压,但对于空气净化机 10 来说,增加出风量后的风压足够使用。
为了更好地描述本实用新型的有益郊果,对有可转动的导风件 19 的风机 13 (即本实用新型的风机 13 )、有不可转动的导风件 19 的风机及无导风件的风机(如图 7 所示)进行的测试对比,具体如下:
环境条件:温度: 27℃ ;湿度: 71% 。
测试地点:技术实验室
测试仪器:稳频稳压电源、电子风量仪、风压表、 JH11 净化机 1 台( 220V/50Hz )、、 噪音计, 其中, JH11 空气净化器使用的叶轮 15 参数为轮叶直径: 250mm ;进口直径: 200mm ;入口角: 40 度;出口角: 50 度;轮叶高度: 80mm ;叶片 18 数量: 36 , JH11 空气净化器使用的导风件 19 的参数如下: 每一所述导风片所在的第一圆线 43 的直径为 270mm ;每一所述导风片所在的第二圆线 44 的直径为 340mm ;每一所述导风片的长度为 100mm ,所应用的导风片的数量为 15 ,导风片的入口角为 10 度, 导风片的出口角为 38 度。
测试步骤:
在无导风件的条件下给 JH11 净化机 通上 220V,50HZ 电源,测试对应的电机 16 功率,电机 16 转速,出风量。并记录到对应表格。
给 净化机 装上导风件 19 ,该导风件 19 不可转动,调整输入电压,使得电机转速同无导风件的测试的电机转速一致,测试在该条件下的电机功率,出风量。并记录到对应表格。
给净化机装上导风件 19 ,该导风件 19 是可转动的,调整输入电压,使得电机转速同无导风件的测试的电机转速一致,测试在该条件下的电机功率,出风量。并记录到对应表格。
当净化机处于高档(转速 1588RPM )时,测试数据如下:
测试项目 无导风件 有导风件(不可转动) 有导风件(可转动)
电机转速( RPM ) 1588 1588 1588
电机功率( W ) 132 135 133
出风量( m ³ /h ) 410 490 470
噪音( dB ) 67 69 66
当净化机处于中档(转速 1290RPM )时,测试数据如下:
测试项目 无导风件 有导风件(不可转动) 有导风件(可转动)
电机转速( RPM ) 1290 1290 1290
电机功率( W ) 87 88 87
出风量( m ³ /h ) 320 380 370
噪音( dB ) 54 57 55
当净化机处于低档(转速 960RPM )时,测试数据如下:
测试项目 无导风件 有导风件(不可转动) 有导风件(可转动)
电机转速( RPM ) 960 960 960
电机功率( W ) 32 32 32
出风量( m ³ /h ) 160 220 230
噪音( dB ) 38 40 40
测试结论:
当使用导风件后,出风效率在各个档位出风效能都有明显提升,而使用可转动的导风轮后,低档时产品出风量明显提升,高档的噪音比固定导风轮有明显改善。
上述实验数据是针对具体 叶轮来测试地,具体叶轮 15 参数为轮叶直径: 250mm ;进口直径: 200mm ;入口角: 40 度;出口角: 50 度;轮叶高度: 80mm ;叶片 18 数量: 36 ,但 轮叶直径 D 与进口直径 d 可根据在相同罩壳 14 下所能够允许的尺寸进行设定,不一定如上述实验中所设计的尺寸参数。同样地,入口角 σ 和出口角 ρ 可以根据在风量要求进行设定,不一定如上述实验中的尺寸参数。在具体实验过程中,也针对不同叶轮尺寸进行了实验,其测试数据及测试结论与上述实验数据相当,在此不加赘述。
对于上述实施例的空气净化机 10 ,叶轮 15 的叶片 18 与导风件 19 的时针方向不同,对于通常技术人员来说,必定会认为,由叶轮 15 排出的气流撞击到导风件 19 上,该空气净化机的噪音会增加很多,但经过上述测试数据可知,有导风件 19 的空气净化机的噪音相对于无导风件的空气净化机的噪音只高出 2 dB ,是用户可以承受的程度。
请同时参阅图 8 ,本领域的普通技术人员看到图 8 时,会想当然认为气流在离开叶轮 15 的叶片 18 外圈时方向发生改变,实际是由于叶轮 15 在转动,所以叶轮 15 内的气流和叶轮 15 外的气流有一个相对的圆周运动,两个方向叠加后的这种导风方式是合适的。
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。
