Description

一种排气扇
技术领域
本发明涉及一种安装在墙壁上预留的开孔内，用于给房间排气换气的具有空气过滤功能的排气扇，属于排气扇的优化技术。
背景技术
通常的排气扇，只有换气功能，包括只能单向换气的排气扇和能够双向换气的排气扇。
也有些排气扇含有简单的空气过滤功能，只能过滤掉较为粗大的粉尘，对于细小的粉尘和PM2.5基本上不起作用。如果想要能够过滤掉细小的粉尘，就需要加大滤网的密度，增加滤网的层数，由于滤网密度和层数增加了，电机的功率也需要相应的增加，否则换气量就会大幅度减小，起不到换气的作用。
市面上的窗式空调扇，能够起到向室内吹风及帮助室内降温的作用。这些空调扇，通常是利用窗户、门洞进行安装的湿式滤网换气扇。其工作原理是在过滤板的顶端设置水管，通过水管中流出的水对过滤板从上向下进行浸淋，使过滤板保持潮湿，当空气流过过滤板时，被过滤板含的水份加湿和降温。这类的窗式空调扇，由于设计目的是换气和降温，所以，通常只设置一层滤网，并且滤网的孔格通常都比较大，只能过滤掉较为粗大的粉尘，过滤不了细小的粉尘，更过滤不了PM2.5。
因此，需要寻找一种不仅换气量大，而且过滤功能更强还能够帮助室内降温的窗式排气扇。
发明内容
本发明的目的是：提供一种不仅换气量大，而且过滤功能强又能够帮助室内降温的窗式排气扇。
本发明的技术方案是：一种排气扇，主要由外壳1和主机组成，安装在墙壁上预留的安装孔内使用，将外壳固定在安装孔内；外壳1对着墙内的一面开孔，主机从开孔进出外壳；主机主要包括机箱以及安置在机箱内的干式滤网2、水箱3、鼓风机4和控制器；机箱朝向干式滤网的一端开口，干式滤网2将开口封住，所述的鼓风机4的进风口端设有导流罩41，导流罩的边缘与机箱的内孔边缘相连，在干式滤网与鼓风机之间形成一个密封的过滤加压仓；过滤加压仓的底壁上设有污水盘5，在污水盘上依次设有两块以上与干式滤网平行的湿式滤网6，这些湿式滤网之间留有空隙，在空隙内设有高压喷淋管7，在高压喷淋管7上设有密集的微形喷孔；水箱3安置在鼓风机导流罩与主机正面之间的空间内，水箱内设有高压水泵，高压水泵与送水管相连，送水管穿过鼓风机的导流罩41进入过滤加压仓并与高压喷淋管7相连；鼓风机的出风口42与主机的出风口相通，将经过过滤、加湿、降温的空气吹出主机；微型喷孔遍布高压喷淋管的壁面，形成360度的喷洒角度。
所述的所有的湿式滤网6，底部都位于污水盘5内，顶部及另两条侧边抵住主机内壁，使进入主机内的空气，必须经过湿式滤网的过滤，才能进入导流罩41。
在污水盘5内设有网格状分隔板，将污水盘分为上水盘和下水盘，在上水盘底壁上铺设污水滤网51，经过污水滤网过滤的水滴进下水盘中；在下水盘与水箱之间设有连接管52，在连接管上设有单向阀和增压水泵。
外壳1位于墙外的一面设有防护罩，防护罩上设有进气格栅。
有益效果：
1、在主机内设置污水盘，在污水盘上设置多个湿式滤网，在湿式滤网之间设置高压喷淋管，喷出细密的水雾和大量负离子，水雾使湿式滤网保持湿润，对进入过滤加压仓的空气进行进一步的过滤、加湿和降温，过滤功能强大，降温效果明显；
2、在过滤加压仓内设置污水盘，对污水进行过滤后再送到水箱中循环再用，节水的同时，减少了加水的频率。
附图说明
图1是本发明的主视结构示意图。
具体实施方式
如图1所示，一种排气扇，主要由外壳1和主机组成，安装在墙壁上预留的安装孔内使用，外壳1位于墙外的一面设有防护罩，防护罩上设有进气格栅；外壳1对着墙内的一面开孔，主机从开孔进出外壳。将外壳固定在安装孔内，防护罩对着墙外，主机工作时，就能够从进气格栅吸入空气，经过过滤、加湿和降温后再吹进室内。
需要对主机进行维护时，只需要从室内就能够将主机从外壳内拉出来，维护完毕再推回外壳内。当把排气扇安装在高层建筑上使用时，从墙外进行维护难度大，而且危险，所以，主机和外壳采用套接的方式，从室内就能够对主机进行维护，减少了维护成本和危险。
主机主要包括机箱以及安置在机箱内的干式滤网2、水箱3、鼓风机4和控制器；机箱朝向干式滤网的一端开口，干式滤网2将开口封住，当空气在鼓风机的吸力作用下从进气格栅进入，首先经过干式滤网进行过滤，把空气中大的粉尘过滤掉。
所述的鼓风机4的进风口端设有导流罩41，导流罩的边缘与机箱的内孔边缘相连，在干式滤网与鼓风机之间形成一个密封的过滤加压仓，经过干式滤网过滤的空气进入过滤加压仓。
过滤加压仓的底壁上设有污水盘5，在污水盘上依次设有一块以上与干式滤网平行的湿式滤网6，这些湿式滤网之间留有空隙，在空隙内设有高压喷淋管7，在高压喷淋管7上设有密集的微形喷孔。水箱3安置在鼓风机导流罩与主机正面之间的空间内，水箱内设有高压水泵，高压水泵与送水管相连，送水管穿过鼓风机的导流罩41进入过滤加压仓并与高压喷淋管7相连。
使用前，在水箱内加水，工作时，鼓风机将墙外的空气吸入过滤加压仓，高压水泵将水箱内的水经送水管送到各高压喷淋管，水从高压喷淋管上的微型喷孔喷出，形成细密的水雾。
微型喷孔遍布高压喷淋管的壁面，形成360度的喷洒角度。喷洒出的水雾喷淋向位于高压喷淋管两侧的湿式滤网，使其保持湿润。水雾会与空气中的粉尘结合形成更大的粉尘颗粒，由于颗粒大了，更容易被湿式滤网阻隔下来。
在湿式滤网表面积聚的水雾及粉尘颗粒，被后续喷淋过来的水雾进一步补充，颗粒越来越大，最后在重力的作用下向下滴淋到污水盘中。也有部分水雾粘住粉尘后直接向下坠落到污水盘中。
进入过滤加压仓的空气，穿过湿式滤网和过滤加压仓的空间时，其中的粉尘和PM2.5大部分被湿式滤网和水雾过滤掉滴入污水盘或粘在湿式滤网上，经过过滤的空气变得更为干净、湿润且温度降低，再被鼓风机吸入加压后从出风口42吹出主机进入室内，给房间提供源源不断的新鲜空气。
所述的所有的湿式滤网6，底部都位于污水盘5内，顶部及另两条侧边抵住主机内壁，使进入主机内的空气，必须经过每一层湿式滤网的过滤，才能进入导流罩41。
每一层湿式滤网的网格大小不同，从进风到出风的方向，网格越来越小，每一层湿式滤网不仅能够过滤掉大小比其网格更大的所有粉尘，在水雾的帮助下，还能过滤掉比其网格更小的粉尘。
每一层湿式滤网，不宜做得过厚，以免降低进气量。
鼓风机的出风口42与主机的出风口相通，高压喷淋管在喷出水雾的同时，还会产生大量负离子，这些负离子随着经过过滤、加湿、降温的空气吹出主机进入室内，使室内的空气保持新鲜。
为使污水能够循环再用，在污水盘5内设有网格状分隔板，将污水盘分为上水盘和下水盘，在上水盘底壁上铺设污水滤网51，经过污水滤网过滤的水滴进下水盘中。在下水盘与水箱之间设有连接管52，在连接管上设有单向阀和增压水泵。下水盘内经过过滤的水，在增压水泵的作用下经连接管52补充到水箱中，再被加压后送到高压喷淋管循环再用。这样不仅能够节水，还能减少向水箱内补水的频率。
在所述的上水盘外壁设有排污阀。对主机进行维护时，将主机从外壳内拉出，拿出干式滤网、湿式滤网和污水滤网进行清洗，打开排污阀，将上水盘中的污水排掉。
在下水盘内设有水位开关。当下水盘内的水位低于预先设定的水位下限时，控制器就不会打开连接管上的增压水泵向水箱内补水。只有当水位超过水位下限，控制器才会打开增压水泵向水箱内补水。相应的，在水箱内也设有水位开关，当水箱内的水位低于水箱水位下限时，控制器发出需要加水的警示，并让鼓风机和水箱里的高压水泵停止工作。
想让降温效果更为明显，通过在水箱内加入冰块或冰球来实现。
上述实施例仅是用来说明解释本发明的用途，而并非是对本发明的限制，本技术领域的普通技术人员，在本发明的实质范围内，做出各种变化或替代，也应属于本发明的保护范畴。
