Description

一种过滤网受风面积大的双侧过滤进风空气净化器 技术领域
本发明涉及空气净化技术领域，具体涉及一种空气净化装置。
背景技术
目前市场上的空气净化器其进风口设置在一侧，离心风轮为一侧开口，离心风轮将空气经由过滤网并从设置在空气净化器一侧的进风口吸入风道，上述现有空气净化器其进风口尺寸与离心风轮直径大致等同，进风口狭小，因此其吸入风道的空气量小，净化的空气量也较小，电机效率低且空气经由过滤网从进风口吸入风道时，外部空气无法穿过过滤网表面的各个角落，进风口附近过滤网即过滤网中间部分使用效率高，其余部分使用效率低，过滤网并不能发挥最大使用效率。如中国发明申请公布专利（申请号201210277744.9）公布的具有新型进风系统的空调器其在空调器两侧增设进风口并在风道外沿开孔，使得两侧进风口空气经由风道外沿开孔绕道风道后侧进风，上述技术方案虽然解决了市场上空气净化器因进风口小导致的吸入风道的空气量小及净化空气量小，风量小的问题，但其结构复杂，同时其两侧进风需绕道损失较大，具有一定的局限性。
技术问题
而且上述目前市场上的空气净化器其进风口设置在一侧，离心风轮为一侧开口，若要同时在净化器上附加加湿和静电集尘功能，加湿叶轮和静电集尘网只能设置在同一侧，而又由于空气净化器内部空间结构限制，静电集尘网距离加湿叶轮距离较近，因此其爬电距离及电器间隙难以满足，因此无法实现同时附加加湿和静电集尘功能。
针对上述问题，有必要对目前市场上的空气净化器进行改进。

优选的，上述辅助风道其进风端与出风端口径收缩截面形状呈漏斗状。
或者，所述电机为双轴电机，所述风轮为单向风轮，双轴电机其两输出轴分别固定连接一个单向风轮。
优选的，所述风道两侧分别设置有三个辅助风道，上述辅助风道设置在风道上远离其出风口的三个边角位置上。
进一步的，所述前机壳还包括前面板，前面板固定安装在前机壳本体上且与前机壳本体保留有供外部空气流入的进风间隙；所述后机壳还包括后面板，后面板固定安装在后机壳本体上且与后机壳本体也保留有供外部空气流入的进风间隙。

后机壳50包括后机壳本体501、第二过滤网502和后面板503，后机壳本体501一体成型有第二腔体，第二过滤网502装置在该后机壳本体其第二腔体上，所述第二腔体其与第二过滤网502贴合的底板上设置有后主进风口501b，位于所述后主进风口501b附近也设置有与风道30上靠近后机壳本体一侧的辅助风道30c连通的后辅助进风口501c；所述后面板503固定连接在后机壳本体501上且与后机壳本体501之间也保留有供外部空气流入的进风间隙；
顶盖60上设置有供净化后空气排出的排气格栅601；前机壳本体401与后机壳本体501拼接形成用于装置单轴电机10、双向风轮20和风道30的空间，顶盖60固定安装在前机壳本体401与后机壳本体501上方且位于风道30其出风口30b上方，净化后空气由风道30其出风口30b流出后再经由顶盖60上的排气格栅601向外排出。
如图3所示为风道30其靠近前机壳本体401一侧的结构示意图，所述风道30除设有由空腔30a与出风口30b形成的主风道外，风道30上远离出风口30b的三个边角位置上还设置有三个辅助风道30c，该辅助风道30c从风道30其靠近前机壳本体一侧贯穿至风道30另一侧即靠近后机壳本体一侧，且所述辅助风道30c其进风端30c-1口径尺寸较大并逐渐收缩成设置在风道30另一侧即靠近后机壳本体一侧的口径尺寸较小的出风端30c-2。又如图4所示，所述辅助风道30c其进风端30c-1与出风端30c-2口径收缩截面形状呈漏斗状，该漏斗状通道即为辅助风道30c。辅助风道30c为漏斗状通道其进风端30c-1口径比出风端30c-2口径大，辅助风道30c其出风端30c-2可形成较大的气压，从而流经辅助风道30c内的气流具有单向性，空气只能由口径大的进风端30c-1流至口径小的出风端30c-2而无法从口径小的出风端30c-2回流至口径大的进风端30c-1，漏斗状通道可避免空气乱流的产生，同时可避免产生乱流杂音。
如图5所示为风道30其靠近后机壳本体501一侧的结构示意图，所述风道30除设有由空腔30a与出风口30b形成的主风道外，风道30上远离出风口30b的三个边角位置上也设置有三个辅助风道30c，该辅助风道30c从风道30其靠近后机壳本体一侧贯穿至风道30另一侧即靠近前机壳本体一侧，且所述辅助风道30c其进风端30c-1口径尺寸较大并逐渐收缩成设置在风道30另一侧即靠近前机壳本体一侧的口径尺寸较小的出风端30c-2，同理设置在风道30其靠近后机壳本体501一侧上的辅助风道30c，其进风端30c-1与出风端30c-2口径尺寸收缩也呈漏斗状。
如图6所示，上述单轴电机10和双向风轮20也可以由双轴电机70和两个分别连接在上述双轴电机70两输出轴上的单向风轮80替代。
如图7所示，上述单轴电机10和双向风轮20也可以由单轴电机和与单轴电机输出轴传动连接的单向可贯通式风轮替代。
上述装置在前机壳本体401其第一腔体401a上的第一过滤网402、装置在后机壳本体501其第二腔体上的第二过滤网502可以为相同功能的过滤网，也可以是不同功能的过滤网，如物理过滤网、静电集尘网或加湿叶轮等不同功能过滤网的配合。
本发明工作原理为：单轴电机10驱动双向风轮20运转或双轴电机70驱动两单向风轮80运转后，外部空气从两侧分别经由前机壳40的第一过滤网402、设置在前机壳本体401上的前主进风口401b，后机壳50的第二过滤网502、设置在后机壳本体501上的后主进风口501b进入风道30其空腔30a；与此同时，外部空气经由前机壳40的第一过滤网402、设置在前机壳本体401上的前辅助进风口401c，进入设置在风道靠近前机壳本体一侧的辅助风道30c其进风端30c-1并经由漏斗状辅助风道30c从设置在风道另一侧即靠近后机壳本体一侧的出风端30c-2吸入至风道30其空腔30a；同时外部空气从另一侧经由后机壳50的第二过滤网502、设置在后机壳本体501上的后辅助进风口501c，进入设置在风道靠近后机壳本体一侧的辅助风道30c其进风端30c-1并经由漏斗状辅助风道30c从设置在风道另一侧即靠近前机壳本体一侧的出风端30c-2吸入至风道30其空腔30a；上述四股风流汇聚经过由空腔30a与出风口30b形成的主风道通过出风口30b排出，最终通过顶盖60上的排气格栅601向外排出，两侧工作原理相同。
为环保，上述风道30采用泡沫、高密度纸或纤维压制成型，也可以采用其他易回收易降解的对环境无害的材料。
对于本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及变形，而所有的这些改变以及变形都应该属于本发明权利要求的保护范围之内。
