Description

一种塔扇过滤网安装结构及塔扇
本申请要求于2018年9月18日提交中国专利局、申请号为201811088925.0、发明名称为“一种塔扇过滤网安装结构及塔扇”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
本发明属于连接结构技术领域，尤其涉及一种塔扇过滤网安装结构及塔扇。
背景技术
塔扇是根据气流学原理，让室内与室外空气形成立体交换系统，塔扇通常是把风通过贯流风机“甩”出，形成气流，也即通过风轮转动后造成风压产生离心式风力最后经过内部导风壁将风力传送出去。由于贯流风轮一般为圆筒状，因此使用塔扇获得的是立体状的气流墙或风幕，该风幕垂直于地面，左右摇摆吹送。贯流风轮具有很多的风叶，送风均匀柔和，非常接近于自然风。塔扇搭配空调使用，形成气流的循环，适合有老人及小孩的家庭，其360度全方位送风，让房间无送风死角，让人感觉舒适。
现有的塔式风扇，大多数不设置过滤网，塔扇吹出的风不能有效过滤空气中的大颗粒，造成损坏塔扇内部结构，也易对人体健康造成影响。同时，考虑到，过滤网若不方便拆卸和再安装，不能独立取出，也很难清理长时间使用的带过滤网塔扇，过滤网不定期清洗，容易附着大量灰尘，造成空气二次污染，不利于用户的健康。

后网组件1包括边框和形成在边框内侧的格网，后网组件1的边框包括长度方向的长边框和宽度方向的短边框，后网组件1的边框上设置有第二拆卸连接组件以及第三拆卸连接组件，后网组件1通过第二拆卸连接组件与过 滤网组件2的第一拆卸连接组件可拆卸连接，进而实现后网组件1与过滤网组件2的可拆卸连接。
后壳组件3包括设置在中部的安装槽和位于安装槽四周的边框，后壳组件3的边框包括长度方向的长边框和宽度方向的短边框，后壳组件3的边框上设置有第四拆卸连接组件，后壳组件3通过第四拆卸连接组件与后网组件1的第三拆卸连接组件可拆卸连接，进而实现后网组件1与后壳组件3的可拆卸连接。
如图2-4所示，示出了本发明的第一实施例，在该实施例中，本发明的塔扇过滤网安装结构包括后网组件1、过滤网组件2以及后壳组件3，过滤网组件2可拆卸地安装在后网组件1与后壳组件3之间。后网组件1、过滤网组件2以及后壳组件3均呈长板状，如矩形平面板状或矩形弧面板状。
实际安装过程中，先将过滤网组件2安装到后网组件1，然后再将安装有过滤网组件2的后网组件1一起安装到后壳组件3上。下面分别说明过滤网组件2与后网组件1的安装结构，以及后网组件1与后壳组件3的安装结构。
过滤网组件2呈长板状，过滤网组件2包括边框和沿宽度方向上设置的多个隔条22，每两个相邻隔条22之间均设置有过滤网，过滤网组件2的边框包括长度方向的长边框和宽度方向的短边框。过滤网组件2上还设置有至少2个导向筋条21，至少2个导向筋条21设置在宽度方向的短边框上，例如导向筋条21呈山字形，并且至少2个导向筋条21不对称地设置在过滤网组件2宽度方向的短边框上，即关于过滤网组件2宽度方向的短边框中心不对称。
后网组件1呈弧面板状，后网组件1包括边框和形成在边框内侧的格网，后网组件1的边框包括长度方向的长边框和宽度方向的短边框，后网组件1上设置有第一限位筋条12、第二限位筋条14、以及至少2个定位卡槽16。第一限位筋条12包括多个并且设置在后网组件1长度方向的第一边框上，第二限位筋条14也包括多个并且设置在后网组件1长度方向的第二边框上，所述第一边框与所述第二边框相对设置。至少2个定位卡槽16设置在后网组件 1宽度方向的短边框上，并且至少2个定位卡槽16不对称地设置在后网组件1宽度方向的短边框上，即关于后网组件1宽度方向的短边框中心不对称。
第一限位筋条12和第二限位筋条14为矩形凸条或U字型凸条，在图2中，第一限位筋条12为U字型凸条，第二限位筋条14为矩形凸条。应注意的是，第一限位筋条12和第二限位筋条14也可采用矩形凸条或U字型凸条的任意组合。定位卡槽16呈U字型槽状，包括底壁和与底壁两侧相连的两侧壁组成。
后网组件1与过滤网组件2装配时，过滤网组件2的至少2个导向筋条21对应插入后网组件1的至少2个定位卡槽16中，同时后网组件1上的第一限位筋条12和第二限位筋条14分别与过滤网组件2的两长边框接触配合定位。导向筋条21和定位卡槽16优选均有2个，从而进一步提高安装过程中的防呆作用。
后网组件1上还设置有多个第一推扣11、多个第二推扣15、至少一个导向板13以及螺钉过孔17。其中，第一推扣11和第二推扣15均呈L字型并且分别设置在后网组件1的两长边框上，L字型的推扣倒扣在后网组件1的长边框上，第一推扣11和第二推扣15均沿后网组件1的长度方向延伸。导向板13和螺钉过孔17分别设置在后网组件1的两短边框上。导向板13为后网组件1短边框上向外凸出的板状体，如矩形板。
后壳组件3包括设置在中部的安装槽和位于安装槽四周的边框，后壳组件3的边框也包括长边框和短边框。过滤网组件2和后网组件1均安装在后壳组件3的安装槽位置。后壳组件3的安装槽内设置有多个宽度方向延伸的横杆35，每个横杆35之间限定出矩形框架。
后壳组件3上设置有多个第一定位槽31、多个第二定位槽33、至少一个导向孔32以及螺钉过孔34，后网组件1的第一推扣11卡入后壳组件3的第二定位槽33中，后网组件1的第二推扣15卡入后壳组件3的第一定位槽31中，后网组件1的导向板13插入后壳组件3的导向孔32中，沿后壳组件3长度方向滑动后网组件1可使后网组件1与后壳组件3配合安装定位。
后网组件1安装到位时，后网组件1上的螺钉过孔17与后壳组件3上 的螺钉过孔34对齐，采用螺钉或螺栓将后网组件1与后壳组件3安装固定，例如采用螺钉将后网组件1与后壳组件3与塔扇内部机身螺钉柱配合连接。后网组件1安装到位时，过滤网组件2的隔条22与后壳组件3的横杆35对齐。
本实施例中，塔扇过滤网安装结构的拆卸方式为：将后网组件1上的螺钉过孔17中的螺钉旋出，推动后网组件1使第一推扣11和第二推扣15从后壳组件3上卸下，然后将过滤网组件2直接从后网组件1上沿着导向筋条21反方向滑出，即可完成拆卸。
如图5-7所示，示出了本发明的第二实施例，该实施例与第一实施例的区别仅在于过滤网组件2与后网组件1的安装结构。下面仅对过滤网组件2与后网组件1的安装结构进行详细说明，相同部分不再赘述。
过滤网组件2上设置有多个导向凸缘121，多个导向凸缘121设置在过滤网组件2的长边框上，导向凸缘121为过滤网组件2的长边框上向外凸出的板状体，如矩形板。过滤网组件2的两侧具有第一短边框123和第二短边框124，短边框123和短边框124的结构尺寸优选不一致，也即短边框123和短边框124采用不对称结构设计，以提供过滤网组件2装配过程中的防呆效果。
后网组件1上设置有第一限位凸缘114、第二限位凸缘116、定位卡槽112，第一限位凸缘114和第二限位凸缘116分别设置在后网组件1的两短边框上，第一限位凸缘114和第二限位凸缘116优选为矩形凸条。定位卡槽112设置在后网组件1的长边框上，例如定位卡槽112设置在后网组件1的第一长边框和/或第二长边框上。定位卡槽112呈U字型槽状，包括底壁和与底壁两侧相连的两侧壁组成，即与第一实施例中的定位卡槽16结构相同。
过滤网组件2上的导向凸缘121插入后网组件1上的定位卡槽112中，后网组件1上的第一限位凸缘114、第二限位凸缘116与过滤网组件2的第一短边框123和第二短边框124配合接触定位。
在本实施例中，塔扇过滤网安装结构的拆卸方式的拆卸方式与第一实施例类似，先将后网组件1上的螺钉过孔17中的螺钉旋出，推动后网组件1 使第一推扣11、第二推扣15从后壳组件3上卸下，过滤网组件2直接从后网组件1上沿着导向凸缘121的反方向滑出，即可完成拆卸。
因此，本实施例相对于第一实施例的区别在于，过滤网组件2上由导向凸缘121替换第一实施例中的导向筋条21，后网组件1上由第二限位凸缘116替换第一实施例中的定位卡槽16，以提供一种不同的连接安装方式。
过滤网组件2上增设第一导向孔23和第二导向孔24，增设的第一导向孔23和第二导向孔24可提高过滤网组件2与后网组件1的连接稳定性。
如图8-10所示，示出了本发明的第三实施例，该实施例与第一实施例的区别仅在于过滤网组件2与后网组件1的安装结构。下面仅对过滤网组件2与后网组件1的安装结构的区别点进行详细说明，相同部分不再赘述。
过滤网组件2上设置有至少2个导向筋条21、第一导向孔223以及第二导向孔224。至少2个导向筋条21与第一实施例中的导向筋条21结构和设置位置相同，第一导向孔223和第二导向孔224分别设置在过滤网组件2的两相对长边框上，第一导向孔223和第二导向孔224为过滤网组件2两相对长边框上设置的缺口。
后网组件1上设置有第一限位筋条12、第二限位筋条14、以及至少2个定位卡槽16，第一限位筋条12、第二限位筋条14、以及至少2个定位卡槽16的结构和设置位置与第一实施例相同。本实施例中，后网组件1在第一实施例的基础上，增设了第一导向孔223和第二导向孔224，两者装配时，后网组件1上的第一限位筋条12和第二限位筋条14分别嵌入过滤网组件2上的第一导向孔223和第二导向孔224，其余的安装结构与第一实施例相同。
因此，本实施例相对于第一实施例的区别在于，过滤网组件2上增设第一导向孔223和第二导向孔224，增设的第一导向孔223和第二导向孔224可提高过滤网组件2与后网组件1的连接稳定性。在本实施例中，塔扇过滤网安装结构的拆卸方式的拆卸方式与第一实施例类似，在此不再赘述。
根据本发明的另一方面，本发明还公开了一种包括上述塔扇过滤网安装结构的塔扇。
本专利的塔扇过滤网安装结构使得塔扇过滤网可拆卸清洗，能有效过滤空气中的大颗粒，并且过滤网拆卸和安装简易方便，清洗过滤网上大量的灰层，可避免空气二次污染。
