Abstract

本发明涉及一种用于旁通管鼓风机马达组件的扩压器盘22，该扩压器盘具有多个翼片(34)，用于在一叶轮箱中从一个叶轮向出口引导气流。每个翼片具有两个弯曲的引导气体的叶片(36)、(37)。叶片(36)轴向和周地向从叶轮向该出口引导气流，而另一叶片(37)径向引导该气流通过出口。

Description

鼓风机马达
技术领域
本发明涉及一种鼓风机马达，尤其涉及用于旁通管或湿型真空清洁器的鼓风机马达。
背景技术
旁通管真空清洁器的鼓风机马达具有一叶轮，该叶轮用于从安装在该马达的一叶轮箱的入口向出口驱动空气而不使其经过马达自身。这种结构可使该真空清洁器在吸灰尘和脏物的同时还能吸液体，而不损坏电动马达。
该叶轮安装在该马达的一轴上。该轴支撑在一轴承上，该轴承穿过该马达箱的一端托架，其还用作该马达与该叶轮之间的间隔物。一个扩压器盘设置在该托架的端部，在该叶轮腔内通过叶轮将空气引导该出口。通常，该扩压器靠在叶轮腔中形成的气压周向和/或轴向地引导该空气，迫使空气通过开口流出。这会导致在该气流路内的阻碍并产生了大量的噪音，以及使得该鼓风机的操作效率低。
发明内容
本发明试图通过引导空气朝着并通过该叶轮箱内的出口通道来解决这一问题。该目的是通过提供一带多个翼片的扩压器盘实现的，该翼片带有两个叶片，用于轴向和径向引导空气。
因此，本发明提供了一种旁通管鼓风机马达组件包括：一马达，该马达包括一轴和支承一用于该轴的轴承的风扇端托架；一安装于该风扇端托架的扩压器盘；一固定在该轴上以在其轴上旋转的叶轮；以及一具有一个入口和多个出口的叶轮箱，该叶轮轴向固定在该入口和出口之间，并用于在二者之间造成气流，而该扩压器盘具有多个周边的翼片，该翼片设置用于从该叶轮向该出口引导该气流，该翼片引导该气流轴向离开该叶轮，周向上分别对准该出口并径向通过该出口。
其它的和/或优选的特征体现在从属权利要求中。
附图说明
通过结合附图将对只作为一个例子的一最佳实施例的进行描述，附图如下：
图1是包括有本发明的扩压器盘的旁通管鼓风机马达组件的部分剖面图；
图2是图1中的组件所使用的风扇端部托架从上部的透视图；
图3是图2中所示托架从下部的透视图；
图4是图1中所示的扩压器盘的从上部的透视图；
图5是图4中所示的扩压器盘的从下部的透视图。
具体实施方式
图1表示旁通管鼓风机马达组件的部分剖面图。该组件具有一马达部分10和一鼓风机部分11。该马达部分包括一通用马达。该马达的操作是众所周知的并将不再进行描述。
该鼓风机部分11包括位于一叶轮腔13内的一离心扇型叶轮12，该叶轮腔13由一拉长的杯形的叶轮箱14限定，该叶轮箱14具有一底壁和一周壁，且二者结合于该马达的一风扇端托架20的一凸缘21。该风扇端托架20将该鼓风机部分11与该马达部分10分开，并封闭该叶轮箱14的开口端。该叶轮箱14在其底壁具有单独一个中央的入口23，在其周壁具有多个出口24。
该通用马达具有一安装在轴承16和17上的轴15。轴承17安装在该风扇端托架20内的一个凸台18上，而轴承17安装在一输入托架19上。该马达10的一定子铁心25夹在该两个端部托架19、20之间。
通过旋转，该叶轮12通过该入口23将空气吸入该叶轮腔13，并通过离心力在该叶轮腔13中压缩该空气，因而迫使该空气从出口24流出。为了操作效果更安静，该出口24并非在轴向与叶轮12对准，且在轴向有所间隔。一个扩压器盘22用于将该气流从该叶轮12引导该出口24。该扩压器盘22具有一用于接触该风扇端托架20的中央部分，其包括一轴向延伸的周边裙部33。该裙部33支承多个翼片34，每个出口24一个，用于将该空气从该叶轮12引导通过该出口24。该翼片34具有两个叶片36、37。一个叶片36从该扩压器盘22的一个轴向面向环绕该周边裙部33的另一曲面延伸。因此叶片36同时轴向及周向引导该空气，使气流对准该出口。叶片36还沿该轴向弯曲，逐渐改变该轴向移动率。另一叶片37沿该裙部33切向延伸，且径向弯曲以缓缓引导并推动该气流流向并通过该出口24。
如图4和5所示，该叶片36从该扩压器盘的一个轴侧向另一轴侧延伸，并最终埋入该风扇端托架20面对轴向面的平面。
上述实施例仅仅以例子的方式给出，且不脱离本发明权利要求书限定的范围的各种变型对于本领域的技术人员来说都是显而易见的。例如，该风扇端托架边缘可具有一轴向的倾斜面，也即一与该扩压器盘(diffuserplate)和风扇匹配的圆锥面。
