Description

一种蜗壳风机组合结构及立式空调器
本申请要求于2015年09月11日提交中国专利局、申请号为201510579470.2、发明名称为“一种蜗壳风机组合结构及立式空调器”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及送风机构领域,具体涉及一种蜗壳风机组合结构及立式空调器。
背景技术
目前市面上的空气调节设备当有双向送风的需求时,有时会设置两个蜗壳风机,朝相反的两个方向送风。但由于蜗壳风机的功率和体积的限制,在比较大型的空气调节设备,例如立式空调上应用时,会出现出风量不足的问题。如果加大蜗壳风机的功率,随之也会增大蜗壳风机的体积,进而需要加大立式空调整体的体积,尤其是增大立式空调的宽度和/或厚度,增加立式空调的横向占用空间,对于立式空调的安装、使用、运输等都是不利的。
发明内容
有鉴于此,本发明提供一种在具有多蜗壳风机的送风装置中能够减少蜗壳风机的出风被相邻的蜗壳风机所影响的蜗壳风机组合结构。
为达此目的,本发明采用以下技术方案:

优选的,在前述的蜗壳风机组合结构中,所述安装板上设有分别对应安装第一蜗壳风机、第二蜗壳风机和第三蜗壳风机的第一风机安装部、第二风机安装部和第三风机安装部,其中所述第二风机安装部相对所述第一风机安装部和第三风机安装部向安装板的前方凸出的设置。
优选的,在前述的蜗壳风机组合结构中,所述第二蜗壳风机出风口的后壁内表面呈平面,所述平面的延长面与和所述第二蜗壳风机出风口相对的第一蜗壳风机和/或第三蜗壳风机的蜗壳不相交。
优选的,在前述的蜗壳风机组合结构中,所述第二蜗壳风机出风口沿从后方至前方的方向朝远离所述第二蜗壳风机的蜗壳的方向倾斜的延伸。
优选的,在前述的蜗壳风机组合结构中,所述第二蜗壳风机具有朝上方出风的第二蜗壳风机第一出风口和朝下方出风的第二蜗壳风机第二出风口;第二蜗壳风机第一出风口后壁内表面呈斜面或弧面,所述的斜面的延长面或者弧面的切面的延长面与所述第一蜗壳风机的蜗壳不相交;第二蜗壳风机第二出风口后壁内表面呈斜面或弧面,所述的斜面的延长面或者弧面的切面的延长面与所述第三蜗壳风机的蜗壳不相交。
优选的,在前述的蜗壳风机组合结构中,
至少在所述双向蜗壳风机第三出风口的前壁,设置平行于所述安装板的第一导流部;和/或至少在所述双向蜗壳风机第四出风口的前壁处,设置平行于所述安装板的第二导流部。
优选的,在前述的蜗壳风机组合结构中,所述第一导流部为向上方延伸的套筒,所述第二导流部为向下方延伸的套筒。
本发明的另一目的是提供一种立式空调器,具体采用以下方案:
一种立式空调器,包括外壳,所述外壳设有位于顶部的顶部出风口和位于底部的底部出风口;还包括设于外壳内的主体风道,所述主体风道分别与所述顶部出风口和所述底部出风口相连通,还包括前述的蜗壳风机组合结构,所 述蜗壳风机组合结构设于所述外壳内,并通过所述主体风道向所述顶部出风口和/或所述底部出风口送风。
本发明的有益效果是:

具体实施方式
以下基于实施例对本发明进行描述,但是本发明并不仅仅限于这些实施例。在下文对本发明的细节描述中,详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本发明。为了避免混淆本发明的实质,公知的方法、过程、流程、元件并没有详细叙述。
在本申请中,方向的定义如图1、2中所示,其中前后方向被定义为沿垂直于安装板4的方向,其中前面板51位于前方,后面板55位于后方;上下方 向被定义为沿平行于安装板的方向,其中顶部出风口53处于上方,下部出风口54处于下方。左右方向被定义为沿平行于安装板的方向并与上下方向垂直,其中图1中左手方向为左侧,右手方向为右侧,对于图2,垂直于纸面方向靠近观察者一侧为左侧,与左侧相反一侧为右侧。
本申请设计一种空气调节设备的蜗壳风机组合结构,包括安装板4和多个蜗壳风机。所述的空气调节设备具体指立式空调、风扇、空气净化器等具有出风功能,能够调节室内空气参数的电器设备。如图1-3中所示,空气调节设备具有外壳5,在外壳5的上方,优选为顶部设有顶部出风口53;在外壳5的下方,优选在外壳5底部的底座上设有底部出风口54;外壳包括前面板51和后面板55,前面板51和后面板55之间围成中空的腔室。所述中空的腔室内设有蜗壳风机组合结构,主要由安装板4和多个蜗壳风机组成,其具体结构会在后面详细的描述。蜗壳风机组合结构沿上下方向布置在所述中空的腔室内,蜗壳设置在安装板4的前方并与前面板51位置相对。安装板4将中空的腔室分成两个独立的部分,安装板4后侧和后面板55之间的空间形成有进风风道57,进风风道57与位于后面板55上的进风格栅相连通,作为优选的方案,进风风道57内部还设有换热机构如蒸发器等。安装板4前侧和前面板51之间的空间形成空气调节设备的主体风道56,主体风道56分别与顶部出风口53和底部出风口54相连通。安装板4上在于蜗壳安装位置相对应的位置设有安装板进风口,安装板进风口的位置与蜗壳进风口位置相对,蜗壳的出风口与主体风道56相连通。当空气调节设备工作时,空气经过后面板55上的进风格栅后进入进风风道57,然后经过安装板进风口进入蜗壳进风口,被蜗壳风机的离心风扇加速后经过蜗壳出风口被送到主体风道56,然后在主体风道56内可向下运动由底部出风口54吹出,和/或向上运动由顶部出风口53吹出。
本申请的蜗壳风机组合结构,包括安装板和安装于安装板前侧面上的至少三个蜗壳风机,至少三个蜗壳风机中包括位于上方的具有设有朝上方出风的出风口的上蜗壳风机,以及位于下方的设有朝下方出风的出风口的下蜗壳风机,还包括设于上蜗壳风机和下蜗壳风机之间的至少一个中间蜗壳风机,至少一个中间蜗壳风机中包括至少一个双向蜗壳风机,所述双向蜗壳风机具有能够上下同时出风的双向出风口,所述双向出风口与和所述双向蜗壳风机相邻的蜗 壳风机在前后方向上错开的设置。至少一个中间蜗壳风机中可以是双向蜗壳风机和单向出风的蜗壳风机的组合,也可以全部是双向蜗壳风机。将双向出风口与和所述双向蜗壳风机相邻的蜗壳风机在前后方向上错开的具体方式可以采用将蜗壳风机前后方向错开、将双向出风口设置为倾斜出风以及上述两种方式的组合,具体结构会在下面详细的说明。
下面以图3-18为例对本申请的蜗壳风机组合结构进行详细的说明。如图5-7所示,蜗壳风机组合结构包括安装板4,以及三个蜗壳风机(以下简称风机)。三个蜗壳风机包括设于安装板4上侧的第一风机1,设于安装板4下侧的第三风机3,以及设于安装板4上并位于第一风机1和第三风机3之间的第二风机2。其中,第一风机1具有朝上出风的第一风机出风口18;第三风机设有朝下出风的第三风机出风口39;第二风机具有两个出风口,其中第二风机第一出风口28设置为朝上出风,第二风机第二出风口29设置为朝下出风。需要说明的是,虽然本实施例中安装板是上下方向设置的,三个蜗壳风机也是上下方向排列的,但是本申请的技术方案不应被局限于上下方向设置的安装板结构中,安装板采用水平布置或倾斜布置均是可以的,本文中所说的上下、左右、前后均是相对于安装板的相对方向。
第二风机2被设置在第一风机1和第三风机3之间,并且出风口被设置为上下出风的方式。如果按照常规的将三个风机安装在同一平面上的方式,第一风机1的蜗壳和第三风机3的蜗壳会对第二风机2的出风形成阻挡,阻碍第二风机2吹出的风顺利的进入主体风道56,为此将三个风机设置成在空间上具有错开的结构,使得第二风机第一出风口28和第二风机第二出风口29与第一风机1和第三风机3的位置在空间上错开,将第一风机1和第三风机3对第二风机2的出风的影响尽可能的降到最低,例如将三个风机在前后方向和/或左右方向错开设置。
作为一种较优的实施方式,如图6中所示,采用的是将三个风机前后错开设置的方式,具体的,将第二风机2在安装板4上的安装位置设置在第一和第三风机的安装位置的前侧,即将第二风机2的设置位置相比较第一风机1和第三风机3的设置位置更靠近主体风道56设置,这样第二风机2的上下方向的出风即可至少部分的避开第一风机1的蜗壳和第三风机3的蜗壳的干扰, 更顺利的通过主体风道56被送出。优选的,将第二风机2在安装板4上的安装位置设置在第一和第三风机的安装位置的前侧是通过改变安装板4的形状来实现的,如图6-8中所示,安装板上具有第一风机安装部41、第二风机安装部42和第三风机安装部43,其中,第二风机安装部42与第一风机安装部41和第三风机安装部43之间形成台阶,使得第二风机安装部42相比较第一风机安装部41和第三风机安装部43向前方的前面板51方向凸出,这样在不改变三个风机的形状的情况下,可使得三个风机被安装于安装板4上时,第二风机2在安装板4上的安装位置位于第一和第三风机的安装位置的前侧。前后错开设置的好处是不增加蜗壳风机组件左右方向的宽度,只是前后方向的厚度有一定的增加,对于空气调节装置的整体尺寸影响比较小。作为一种较优的方式,第二风机第一出风口28和第二风机第二出风口29的后壁内表面可以呈平行于安装板的平面,平面的延长面分别与第一风机1和第三风机3的蜗壳不相交。这样可使第二风机2的出风不会吹到第一风机1和第三风机3的蜗壳上,将第一风机1和第三风机3的蜗壳对第二风机2的出风的影响降到最小
还可以采用将三风机在左右方向上错开的方式(图中未示出),即将第二风机2布置在第一风机1和第三风机3的左侧或者右侧,也可实现降低第一风机1和第三风机3对第二风机2的出风的干扰,但这种方式会大幅增加蜗壳风机组件的左右方向的宽度,不利于空气调节装置的整体布局。
作为另一种较优的实施方式,还可以将第二风机2的第二风机第一出风口28和第二风机第二出风口29设至为相对于第二风机2的蜗壳倾斜的设置。以图3-6为例,在实际安装状态下,第二风机2的蜗壳以基本平行于安装板4的第二风机安装部42的平面的方式安装,如图3中所示,第二风机2的蜗壳平面基本沿上下方向延伸。第二风机第一出风口28和第二风机第二出风口29被设置为从安装板4到前面板51的方向(即前后方向)朝远离蜗壳的方向延伸,具体的,第二风机第一出风口28被设置为朝前上方向出风,第二风机第二出风口29被设置成为朝前下方向出风。参见图6、10、11,第二风机第一出风口28包括靠近第二风机安装部42的第二风机第一出风口后壁内表面282和靠近前面板51的第二风机第一出风口前壁内壁281,第二风机第一出风口前壁内壁281可以呈斜面或者弧面,斜面或者弧面的切面的延长面2811与安 装板4平面呈第一倾角θ1;第二风机第一出风口后壁内表面282可以呈斜面或者弧面,斜面或者弧面的延长面2821与安装板4平面呈第二倾角θ2。第一倾角θ1与第二倾角θ2的大小可相同或者不同。第二风机第二出风口29具有靠近第二风机安装部42的第二风机第二出风口后壁内表面292和靠近前面板51的第二风机第二出风口前壁内壁291,第二风机第二出风口前壁内壁291可以呈斜面或者弧面,斜面或者弧面的切面方向2911与安装板4平面呈第三倾角θ3;第二风机第二出风口后壁内表面292可以呈斜面或者弧面,斜面或者弧面的切面方向2921与安装板4平面呈第四倾角θ4。第三倾角θ3与第四倾角θ4的大小可相同或者不同。作为一种优选的方式,第二风机第一出风口后壁内表面282的斜面的延长面或者弧面的切面的延长面2821与第一风机1的蜗壳不相交,如图4中所示;第二风机第二出风口后壁内表面292的斜面的延长面或者弧面的切面的延长面2921与第三风机3的蜗壳不相交(图中未示出);不相交的含义具体是指,斜面的延长面或者弧面的切面的延长面2821上的与蜗壳在安装板上投影重合的部分在前后方向上位于蜗壳的前方。通过这样设置,可使得由第二风机第一出风口28和下出风口29吹出的风不会吹到第一风机1和第三风机3的蜗壳上,可减少第一风机1和第三风机3的蜗壳对第二风机2的出风的干扰。
作为另一种较优的实施方式,采用上述错开方式的组合,如图3-7中所示的,安装板上具有第一风机安装部41、第二风机安装部42和第三风机安装部43,其中,第二风机安装部42与第一风机安装部41和第三风机安装部43之间形成台阶,使得第二风机安装部42相比较第一风机安装部41和第三风机安装部43向前方的前面板51方向凸出;同时,将第二风机第一出风口28和第二风机第二出风口29被设置为相对于蜗壳倾斜的设置,即从安装板4到前面板51的方向(即前后方向)朝远离蜗壳的方向延伸。优选的,第二风机第一出风口后壁内表面282的斜面的延长面或者弧面的切面的延长面2821与第一风机1的蜗壳不相交,如图4中所示;第二风机第二出风口后壁内表面292的斜面的延长面或者弧面的切面的延长面2921与第三风机1的蜗壳不相交。这样组合的错开方式既可以降低前后方向错开导致的蜗壳风机组合结构的厚度(前后方向)的增加,同时也可避免第二风机第一出风口28和第二风机第 二出风口29相对于蜗壳倾斜的角度过大影响蜗壳风机出风,保证蜗壳风机组合结构的厚度(前后方向)和宽度(左右方向)都没有较大的尺寸的增加,有利于空气调节设备的整体结构优化设计,同时第一风机和第三风机对第二风机的出风的干扰也比较低,使得三个风机的出风能够顺畅的在主体风道56内运动。
作为另一种较优的方式,可以在第二风机的倾斜设置的第二风机第一出风口28和/或第二风机第二出风口29处设置导流部,如图12所示,在第二风机第一出风口28处设有上导流部280,在在第二风机第二出风口29处设置下导流部290。上导流部280至少设置在第二风机第一出风口28的前壁,即靠近前面板51的位置处;下导流部290至少设置在第二风机第二出风口29的前壁,即靠近前面板51的位置处;上导流部280、下导流部290整体大致呈平行于安装板4和/或前面板51的方式,即沿上下方向延伸,优选的,上导流部280、下导流部290具有套筒的结构,套筒设在第二风机第一出风口28和第二风机第二出风口29处,套筒沿大致上下方向延伸。这样由上出风口28和下出风口29吹出的风会以基本平行于主体风道56的走向的方式进入主体风道56内,可减少前面板51反射气流对主体风道56内气流的干扰,使主体风道56内的气流更加平顺,减少能量损失。同时如果顶部出风口53或底部出风口54之一被封闭,如图3B所示,以底部出风口54被关闭为例,此时第二风机第二出风口29和第三风机出风口39向下方吹出的风运动到主体风道56的下端后折返,经过第三风机3与第二风机2的蜗壳与前面板51之间形成的通道向顶部出风口53运动,由于下导流部290的存在,下出风口29向下吹出的风基本平行于主体风道56,下部折返的风经过第二风机2的蜗壳和前面板51之间的通道时不会受到下出风口29出风的干扰从而能顺利的向上运动。如果不设置下导流部290,下出风口29的向前下方的倾斜出风会对下部折返的风造成阻碍,使折返的风不能顺畅的向上运动。同理适用于上导流部280,当顶部出风口53被关闭时上导流部280所起的作用与下导流部290所起的作用相同。
下面对蜗壳风机组件的具体安装方式进行说明,如图7-9所示的结构。安装板上具有第一风机安装部41、第二风机安装部42和第三风机安装部43,第一风机安装部41、第二风机安装部42和第三风机安装部43上分别设有第一 风机安装面,第二风机安装面和第三风机安装面(图中未示出),其中第二风机安装面相对于第一风机安装面和第三风机安装面朝向前面板51方向凸出的设置;第一风机安装面和第三风机安装面的边缘设有围板可增强安装板的整体强度,同时使得第一风机安装部41和第三风机安装部43形成凹陷部,如图8中所示;第一风机安装面,第二风机安装面和第三风机安装面上分别形成有第一安装板进风口411,第二安装板进风口421,第三安装板进风口431,如图8所示。风机的蜗壳由两个半壳组成,两个半壳拥有大致相同的厚度,优选的,两个半壳由蜗壳从与蜗壳轴线垂直的中线处剖开形成,这样设置便于半壳的制造。具体的,第一风机1包括第一风机后半壳15、第一风机前半壳13、第一电机11、第一叶轮14,第一风机后半壳15与第一风机前半壳13组成第一蜗壳,第一风机后半壳15上开设有第一蜗壳进风口,第一电机11和第一叶轮14安装在第一风机前半壳13上;第二风机2包括第二风机后半壳25、第二风机前半壳23、第二电机21、第二叶轮24,第二风机后半壳25与第二风机前半壳23组成第二蜗壳,第二风机后半壳25上开设有第二蜗壳进风口,第二电机21和第二叶轮24安装在第二风机前半壳23上;第三风机3包括第三风机后半壳35、第三风机前半壳33、第三电机31、第三叶轮34,第三风机后半壳35与第三风机前半壳33组成第三蜗壳,第三风机后半壳35上开设有第三蜗壳进风口,第三电机31和第三叶轮34安装在第三风机前半壳33上;具体如图9所示。
当第一风机1、第二风机2、第三风机3被分别安装到第一风机安装部41、第二风机安装部42和第三风机安装部43上时,先将第一风机后半壳15、第二风机后半壳25、第三风机后半壳35分别通过连接件固定到第一风机安装部41、第二风机安装部42和第三风机安装部43的第一风机安装面、第二风机安装面和第三风机安装面上,所述连接件可以是螺钉、螺栓、铆钉等,如图8B所示,采用的是螺钉91的方式。第一蜗壳进风口、第二蜗壳进风口、第三蜗壳进风口分别与第一安装板进风口411,第二安装板进风口421,第三安装板进风口431相对。由于第一风机安装部41和第三风机安装部43形成凹陷部,所述第一风机后半壳15和第三风机后半壳35嵌入所述凹陷部内,第二风机后半壳25位于第二风机安装部42上突出于安装板4。第一风机前半壳13、第二 风机前半壳23、第三风机前半壳33在安装好对应的电机和叶轮后被一体的分别与第一风机后半壳15、第二风机后半壳25、第三风机后半壳35相连接,进而组成整个蜗壳风机组合结构,如图9所示。相比较传统的将电机固定到安装板的方式,本申请的电机被安装在蜗壳上,电机和叶轮可同蜗壳一起拆卸,不需要拆卸安装板,提高了整体的组装便捷性和可维护性。蜗壳风机的具体结构将在后面详细的说明。
下面以第一风机1与安装板4为例对蜗壳风机的安装结构进行详细的说明,如图13-18中所示的。在以下的说明中,轴向方向被定义为与电机轴线平行的方向,径向方向被定义为与电机轴线垂直的方向,周向方向被定义为绕电机轴线旋转的方向;侧方均是相对于电机轴线方向而言,例如图13中第一半壳13(第一风机前半壳)位于一侧,第二半壳15(第一风机后半壳)位于另一侧,叶轮14位于第一半壳13和第二半壳15的中间。
如图15所示的,所述蜗壳从包含电机的轴线111的平面切断蜗壳得到的轴向截面上看,在所述轴线方向上靠近蜗壳中线的蜗壳周壁到所述轴线的距离大于在轴线上位于两侧的蜗壳周壁距离所述轴线111的距离,该距离是周壁中线到叶轮的轴线144的距离,差值为H。优选的,在所述轴线111方向上靠近蜗壳中线139的蜗壳周壁外壁到所述轴线111的距离大于在轴线111上位于两侧的蜗壳周壁外壁距离所述轴线111的距离,其差值为H1(图中未示出)。优选的,蜗壳的周壁外壁的轴向截面可以是弧形、梯形、切边的弧形、三角形或者其他多边形。优选的,所述蜗壳从包含所述电机的轴线111的平面切断蜗壳得到的轴向截面上看,在所述轴线111方向上靠近蜗壳中线139的蜗壳周壁内壁到所述轴线111的距离也大于在轴线上位于两侧的蜗壳周壁内壁距离所述轴线111的距离,其差值H2(图中未示出)。H1、H2可以与H相同或者不同,具体取决于蜗壳周壁的厚度变化;优选的,蜗壳的周壁内壁的轴向截面也可以是与周壁外壁的形状相匹配的弧形、梯形、切边的弧形、三角形或者其他多边形。通过将蜗壳的周壁外壁设计成中间突出的结构,可以适应不同的如具有曲线外壳的立式空调结构。此外,由于蜗壳周壁的厚度通常是均匀的,所以周壁外壁的凸出会使周壁内壁也呈凸出的结构,对比周壁与侧壁相垂直的蜗壳可增大蜗壳内部的容积,提高蜗壳风机的送风能力。
为了便于制造,可将蜗壳设置成分体的结构。如图13-15中所示。蜗壳包括第一半壳13和第二半壳15,第一半壳13包括第一半壳周壁131和第一半壳侧壁132,第二半壳包括第二半壳周壁151和第二半壳侧壁152,第一半壳周壁131和第二半壳周壁151以包围叶轮14的外周的方式弯曲。第一半壳周壁131包括与第一半壳侧壁132的边缘部相连接的固定端和远离第一半壳侧壁132的第一连接端1311,第二半壳周壁151包括与第二半壳侧壁152的边缘部相连接的固定端和远离第二半壳侧壁152的第二连接端1311,第一半壳周壁131的第一连接端1311与第二半壳周壁151的第二连接端1311相连接,从而使得第一半壳13和第二半壳15的内部形成容置腔,其用于容纳该叶轮14,并形成为相对于电机轴线111而言的半径沿叶轮14的旋转方向变大的筒状。
本实施例中的蜗壳风机的电机11包括电机本体117和旋转轴112。所述叶轮14安装在容置腔内,其成为在电机轴线111的轴向上细长地形成的多张叶片141相对于电机轴线111呈放射状且以规定间隔配置而成的圆筒形状。叶片141的一端安装于大致圆形的旋转圆板142的外缘部分,叶片141的另一端安装于环状的支承环143并在内部形成叶轮进风口。旋转圆板142在中央固定于电机的旋转轴112,在电机11的驱动下,叶轮14以旋转轴112为中心进行旋转。第一半壳13上设有电机安装口133,所述叶轮的旋转圆板142靠近所述电机安装口133设置,电机11的旋转轴112穿过电机安装口与叶轮14的旋转圆板142相连接,进而带动旋转圆板142转动,所述第二半壳15上设有蜗壳进风口153,蜗壳进风口153与叶轮进风口位置相对应用于向叶轮14内侧引导空气。电机本体117由第一半壳13所支撑。在电机本体117与第一半壳13之间设置有第一减振装置,第一减振装置的结构和具体安装方式将在下面进行详细的描述。
由于蜗壳通常采用塑料材料制作,整体强度不高,将电机本体117直接安装到第一半壳13上可能会导致第一半壳13的强度不足以支撑电机的动力导致第一半壳13变形或者损坏,为此作为一种较优的实施方式,包括支撑盘12,所述支撑盘12由金属材料制作,所述支撑盘12固定在所述第一半壳13上,优选的固定在第一半壳13的第一半壳侧壁132的外壁上,电机本体117固定在支撑盘12上。优选的,电机本体117固定在支撑盘12的远离第一半壳13 的侧面上。通过设置支撑盘12,可使得电机本体117能够设置在蜗壳上并由蜗壳支撑,同时不会对蜗壳产生变形或者损害。
当设置有支撑盘12时,可将第一减振装置设置在支撑盘12和电机本体117之间。在电机本体117的周壁外壁上设置凸缘133,凸缘133被固定到支撑盘12上,第一减振装置设置在凸缘133与支撑盘12之间。优选的,所述第一减振装置优选为设置在凸缘133和支撑盘12之间的第一减振垫圈114。作为一种优选的方案,如图13中所示,第一减振垫圈114设置为柱状,柱状的第一减振垫圈114的外周上设置有插口,凸缘133为片状,从所述插口插入到第一减振垫圈114的内部,第一减振垫圈114上设有与凸缘133的安装孔连通的贯通孔,连接件如螺钉、螺柱穿过第一减振垫圈114的贯通孔和凸缘133的安装孔后与支撑盘12相连接进而固定电机本体117。第一减振垫圈114优选采用橡胶支座。当不设置支撑盘12时,电机11也可以将支撑盘12替换为第一半壳13的方式通过上述的第一减振装置与第一半壳13直接连接。
所述第一半壳周面131从固定端到第一连接端1311在径向方向上朝远离电机轴线111的方向延伸,第二半壳周面151从固定端到第二连接端1311在径向方向上朝远离电机轴线111的方向延伸。优选的,第一半壳周壁131的第一连接端1311与第二半壳周壁151的第二连接端1311的连接处靠近垂直于电机轴线111的蜗壳中线139或与垂直于电机轴线111的蜗壳中线139重合。
为了提升蜗壳的气密性,可在第一半壳13与第二半壳15的连接处设置密封结构。优选的,该密封结构为设置在第一半壳周壁131的第一连接端1311与第二半壳周壁151的第二连接端1311中的一个上的凸筋和设置在另一个上的凹槽,优选的,图15中所示的,在第一半壳周壁131的第一连接端1311上设有朝向第二半壳15延伸的凸筋1312,在第二半壳周壁151上与凸筋1312相对应的设有凹槽1512,第一半壳13与第二半壳15相连接时,凸筋1312嵌入所述凹槽1512内,可提高半壳的密封性,避免蜗壳的周壁漏风以降低蜗壳风机的效率。凸筋1312和凹槽1512的结构可以设置一道也可设置多道。
密封结构还可以采用密封圈的形式,通过在第一半壳13与第二半壳15中的一个上设置凸缘,另一个上设置凹槽,凸缘与凹槽抵接并将密封圈压紧在凹槽内以实现密封。密封圈可采用橡胶或其他软质的材料。密封结构设置在蜗 壳的周壁的径向外侧或者径向内侧均可。
作为一种较优的实施方式,如图15中所示,旋转圆板142从边缘向着旋转圆板142的轴心的方向朝叶轮14的内部突出的设置,旋转圆板142呈现为大致碗形或者锥形,旋转圆板142的径向内侧形成电机容纳空间,电机的旋转轴112穿过蜗壳进入蜗壳内,电机主体117的一部分可位于电机容纳空间内,这样做的好处是可以减少电机11突出于蜗壳外部的长度,减小蜗壳风机轴向方向上的安装宽度,使得蜗壳风机整体结构更加的紧凑。此时,对应的将第一半壳13的第一半壳侧壁132的上形成内凹部1321,内凹部1321的中心设有电机安装口133,内凹部1321也设置为从边缘向着电机安装口133的轴心的方向朝叶轮14的内部突出的设置。
