本申请基于申请号为202310672298.X、申请日为2023年6月7日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及空调技术领域，例如涉及一种用于空调滤网的自清扫结构和空调器。
背景技术
目前的空调室内机通过风扇系统对室内空气进行交换，其中在风扇系统前设置有过滤网，该过滤网能拦截空气中的灰尘、毛絮等脏物。但是随着空调室内机的长期运行，堆积在过滤网表面的脏物越来越多，如不及时清除，可能会滋生病菌，甚至产生异味，造成室内空气二次污染；此外，还会影响进风量，从而影响空调性能。
现阶段主要通过以下方式清扫过滤网，通过吸尘装置吸取过滤网上的灰尘；或者，通过毛刷清扫过滤网上的灰尘；又或者，通过驱动机构驱使过滤网与毛刷或吸尘装置同时运动清扫灰尘。比如相关技术中提供一种过滤网除尘机构。过滤网除尘机构包括分别用于过滤网收卷和展开的收卷装置和展开装置，其中，收卷装置上设置有除尘部，在过滤网收卷和/或展开过程中，过滤网上的灰尘会被除尘部清除。由此，实现了过滤网上灰尘的自动清理，提高了空调出风的净化程度，改善了空调出风质量。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
为便于清扫过滤网，在空调室内机中集成设置有滤网导向机构和除尘机构，但是过滤网的设置位置是在空调室内机的进风口和换热器之间。在换热器的温度过高或过低的情况下，滤网导向机构可能发生变形，从而导致导向失效，进而滤网运动容易产生变形，不仅影响滤网的清洁，甚至使滤网堆叠发生卡顿、卡死等问题。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

结合图1、图2、图5、图14以及图16所示，本公开实施例提供一种用于空调滤 网的自清扫结构，包括滤网安装架10、转动卷轴组、滤网104和集尘装置40。滤网安装架10，相对两侧构造有第一卷轴安装空间11和第二卷轴安装空间12，第一卷轴安装空间11和第二卷轴安装空间12之间具有龙骨架13；其中，第一卷轴安装空间11和/或第二卷轴安装空间12具有开口，且在开口的侧边形成有支撑板14；转动卷轴组，包括第一卷轴20和第二卷轴30，第一卷轴20转动设置于第一卷轴安装空间11内，第二卷轴30转动设置于第二卷轴安装空间12内；滤网，设置于龙骨架13和支撑板14的第一支撑面141，且第一侧边可拆卸地连接在第一卷轴20上，第二侧边可拆卸地连接在第二卷轴30上；其中，滤网104预缠绕在第一卷轴20或第二卷轴30上，且预缠绕的长度大于或等于滤网104移动的路径距离；集尘装置40，设置于支撑板14的第一支撑面141侧，集尘装置40具有与滤网抵接的毛刷组件42，用于清扫第一支撑面141处的滤网104。
采用本公开实施例提供的空调滤网的自清扫结构，第一卷轴安装空间11和第二卷轴安装空间12之间具有曲面结构的龙骨架13，第一卷轴安装空间11和/或第二卷轴安装空间12具有朝下的开口侧边形成有支撑板14，第一卷轴20转动设置于第一卷轴安装空间11内，第二卷轴12转动设置于第二卷轴安装空间12内。这样，在滤网104移动的过程中，曲面结构的龙骨架13和支撑板14能对整个滤网104的表面提供有效的支撑，从而防止滤网侧边发生弯曲或变形，能使滤网充分发挥过滤的作用。此外，滤网104预缠绕在第一卷轴20或第二卷轴30上，且预缠绕的长度大于或等于滤网104移动的路径距离，这样，即使在进行清洁滤网的情况下，预缠绕部分的滤网还可以起到过滤的作用。在此基础上，在支撑板14的第一支撑面141下方还设置有集尘装置40，通过毛刷组件42清扫第一支撑面141处的滤网104，能使毛刷组件42充分的与滤网104接触，使得清扫效果更好。
在本公开实施例中，滤网安装架10的相对两侧构造有第一卷轴安装空间11和第二卷轴安装空间12，第一卷轴安装空间11和第二卷轴安装空间12之间具有曲面结构的龙骨架13。可选地，第一卷轴安装空间11具有朝下的开口，且在开口的侧边形成有支撑板14。可选地，第二卷轴安装空间12具有朝下的开口，且在开口的侧边形成有支撑板14。可选地，第一卷轴安装空间11和第二卷轴安装空间12均具有朝下的开口，且在开口的侧边形成有支撑板14。
这里，相比于平面结构的龙骨架，第一卷轴安装空间11和第二卷轴安装空间12之间的曲面龙骨架13以及支撑板14能够将滤网104支撑起来，保证滤网104不会弯曲变形，无需在侧边设置导向结构。进而在制冷或制热的情况下，不会影响滤网104移动。
在本公开实施例中，第一卷轴20能够实现滤网的展开或者滤网的收卷，第二卷轴30也能够实现滤网的展开或者滤网的收卷。这里，滤网的长度是足够长的，无论是展开或者收卷，滤网均能实现过滤的作用。这样，通过第一卷轴20和第二卷轴30的配合使用，完成滤网的展开或收卷。
在本公开实施例中，转动卷轴组的第一卷轴20转动设置于第一卷轴安装空间11内，转动卷轴组的第二卷轴30转动设置于第二卷轴安装空间12内。此外，滤网104的第一侧边可拆卸地连接在第一卷轴20上，滤网104的第二侧边可拆卸地连接在第二卷轴30上；滤网104能通过绕设的方式缠绕在卷轴上，能使滤网两侧边受力更加均匀，防止滤网两侧边局部变形，避免出现滤网堆叠等问题。在此基础上，滤网104预缠绕在第一卷轴20或第二卷轴30上，且预缠绕的长度大于或等于滤网104移动的路径距离；即使在进行清洁滤网的情况下，预缠绕部分的滤网还可以起到过滤的作用。此外，通过卷轴缠绕滤网的形式，缩小来整个自清扫结构的体积，因此不遮挡进风口的进风面积，从而提高空调的风量，提高制冷制热的效果。
在本公开实施例中，集尘装置40设置于支撑板14的第一支撑面141下方，集尘装置40具有与滤网抵接的毛刷组件42。支撑板14的第一支撑面141能对滤网104提供有效的支撑，防止滤网变形。在进行清扫滤网的情况下，由于滤网能与毛刷组件42的刷毛抵接，从而使毛刷能充分的与滤网104接触，进而使清扫效果更好。
结合图3至图5所示，在一些实施例中，龙骨架13与滤网接触的表面为第二支撑面，在第二支撑面上设置有滑动结构和/或滚动结构。由于滤网是柔性网状结构，龙骨架13能对整个滤网10的表面提供有效的支撑，防止滤网发生弯曲、变形等问题，进而使滤网能充分发挥过滤的作用。此外，在龙骨架13的第二支撑面设置有滑动结构和/或滚动结构，滤网的表面与滑动结构和/或滚动结构接触，在滤网移动的过程中，能减小与龙骨架13的摩擦力，不仅能减少滤网移动产生噪音，还能防止滤网破损等问题。
在本公开实施例中，滤网安装架10用于设置在空调的进风口下方，且位于换热器100的上方，用于过滤空调进风口的灰尘、杂质等。其中，滤网安装架10包括框体101和空调连接架102。这里，框体101和空调连接架102的形状相匹配，空调连接架102固定安装换热器100的上方，框体101可拆卸安装在空调连接架102上。
在本公开实施例中，由于滤网104设置在龙骨架13的上方。这里，为了使龙骨架13能够提供有效的支撑，龙骨架13由多个肋条组成，多个肋条之间具有较大的间距，用于空调进风。
可选地，龙骨架13可以为多个排列设置的竖向肋条组成，竖向肋条的与滤网的移动方向为垂直设置。可选地，龙骨架13可以为多个排列设置的横向肋条组成，横向肋条的与滤网的移动方向为平行设置。可选地，龙骨架13可以为多个交错设置的横向肋条和竖向肋条组成。可选地，龙骨架13可以为多个斜向肋条组成。
结合上述实施例，无论龙骨架13采用哪种结构，在龙骨架13的第二支撑面侧均设置有滑动结构和/或滚动结构，即在肋条侧均设置有滑动结构和/或滚动结构，从而能有效减少滤网与龙骨架13的接触面积。这样，能减少龙骨架13对滤网的阻力。同时，还能减少滤网移动产生噪音。此外，由于是滤网为柔性网布，与滑动结构和/或滚动结构滑动接触，也能防止滤网破损。
结合图3至图5所示，在一些实施例中，滑动结构131包括设置在龙骨架13上的 多个弧形凸起。使得滤网能在龙骨架13上顺畅的滑动。
在本公开实施例中，以龙骨架13为多个交错设置的横向肋条和竖向肋条组成例。这里，横向肋起到将多个竖向肋条固定连接在一起，保证整个龙骨架13的稳定性，防止竖向肋条弯曲或折断。其中，滑动结构131包括多个弧形凸起，该弧形凸起设置在竖向肋条上，即弧形凸起的数量与竖向肋条的数量相同。此外，弧形凸起的长度是与竖向肋条的长度相匹配的，该弧形凸起的截面为拱状结构。在滤网移动的过程中，滤网与弧形凸起的最上部接触，相比于与肋条接触，大大减小了接触面积，进而不仅能起到支撑作用，还能使滤网在龙骨架13上顺畅的滑动，避免滤网叠堆卡在框体101上。
在一些实施例中，滚动结构包括设置在龙骨架13上的多个转动滚轴。使得滤网能在龙骨架13上顺畅的移动。
在本公开实施例中，以龙骨架13为多个交错设置的横向肋条和竖向肋条组成例。其中，滑动结构131包括多个转动滚轴(图中未示出)，该转动滚轴设置在竖向肋条上，转动滚轴的数量与竖向肋条的数量相同。该转动滚轴包括在竖向肋条上开设的通槽，滚轴的轴体在通槽内转动。这样，在滤网移动的过程中，能从滑动摩擦变为滚动摩擦，进一步减小对滤网的阻力，使得滤网能在龙骨架13上顺畅的移动，避免叠堆卡在框体101上。
结合图4和图5所示，在一些实施例中，龙骨架13的截面为曲面结构。这样，能保证滤网始终与龙骨架13接触，同时将滤网完全撑开。
在本公开实施例中，由于滤网是柔性网布，在没有支撑力的情况下，自身容易褶皱变形。因此，可以通过两端部的力使滤网为绷直状态。这里，第一卷轴安装空间11与第二卷轴安装空间12之间是具有高度差的，并且在第一卷轴安装空间11和第二卷轴安装空间12之间设置有的龙骨架13具有弧度，使得龙骨架13形成拱形。这样通过第一卷轴20和第二卷轴30能将滤网变为绷直状态，同时龙骨架13能支撑滤网，使滤网始终与龙骨架13相接触。
结合图6所示，在一些实施例中，框体101的侧边框上设置有与空调连接架102可拆卸连接的侧端连接部103。其中，在空调连接架102上设置有相应的配合结构，用于与侧端连接部103可拆卸连接。
结合图6所示，在一些实施例中，侧端连接部103包括固定结构1031，设置于框体101的侧边框中部，用于空调连接架102与框体101连接固定。
在本公开实施例中，在框体101的侧边框中部设置有固定结构1031，相应地，空调连接架102上设置有相应的固定配合结构。这样，固定结构1031与固定配合结构能将框体101固定在空调连接架102上。这里，固定结构1031和固定配合结构两者中的一个为卡扣，固定结构1031和固定配合结构两者中的另一个为卡槽。其中，在固定结构1031为卡扣的情况下，固定配合结构为卡槽；在固定结构1031为卡槽的情况下，固定配合结构为卡扣。这样，通过卡扣与卡槽相互卡接，以使框体101与空调连接架 102连接固定。
结合图6所示，在一些实施例中，侧端连接部103还包括定位结构1032，设置于框体101的侧边框两端部。用于定位空调连接架102与框体101连接定位。
在本公开实施例中，在框体101的侧边框中部设置有定位结构1032，相应地，空调连接架102上设置有相应的定位配合结构。这里，框体101的侧边框设置有固定结构1031和定位结构1032，空调连接架102上设置有固定配合结构和定位配合结构，固定结构1031和固定配合结构在定位结构1032和定位配合结构的定向方向上的卡合位置卡合。其中，固定结构1031和固定配合结构用于保证框体101与空调连接架102之间的连接稳定性；定位结构1032和定位配合结构用于保证框体101与空调连接架102之间的连接准确性。这样，方便框体101与空调连接架102之间连接固定。
可选地，定位结构1032和定位配合结构两者中的一个为定位导轨，定位结构1032和定位配合结构两者中的另一个为定位槽。其中，在定位结构1032为定位导轨的情况下，定位配合结构为定位槽；在定位结构1032为定位槽的情况下，定位配合结构为定位导轨。
结合图7所示，在一些实施例中，第一卷轴20沿其轴向的表面上设置有第一安装结构21，滤网的第一侧边可拆卸地连接在第一安装结构21；第二卷轴30沿其轴向的表面上设置有第二安装结构31，滤网的第二侧边可拆卸地连接在第二安装结构31。
在本公开实施例中，转动卷轴组的两个卷轴均用于安装滤网，这样，第一卷轴20和第二卷轴30能组成转动结构。其中，第一卷轴20和第二卷轴30均为圆杆结构，这样，在滤网安装在第一卷轴20和第二卷轴30的情况下，可以通过多种方式使滤网移动。可选地，通过第一卷轴20的主动转动带动第二卷轴30从动转动。可选地，通过第二卷轴30的主动转动带动第一卷轴20从动转动。可选地，通过第一卷轴20和第二卷轴30的同步主动转动。
由于滤网预缠绕在第一卷轴20或第二卷轴30上，且预缠绕的长度大于或等于滤网移动的路径距离。因此为了防止滤网安装架10妨碍滤网104移动，在一些实施例中，第一卷轴20的周向表面与第一卷轴安装空间11的内壁之间具有设定间距；第二卷轴30的周向表面与第二卷轴安装空间12的内壁之间具有设定间距。这样，能保证第一卷轴20或第二卷轴30上的滤网不会与第一卷轴安装空间11或第二卷轴安装空间12接触，从而使滤网可以顺畅地移动。
可选地，结合图5所示，第一卷轴安装空间11和第二卷轴安装空间12均为弧形槽体结构，由于第一卷轴20和第二卷轴30均为圆杆结构，因此第一卷轴20在第一卷轴安装空间11内的安装形式与第二卷轴30在第二卷轴安装空间12内的安装形式相同。这里，以第一卷轴20安装在第一卷轴安装空间11内为例，第一卷轴20的两端分别连接在弧形槽体的两端，并且第一卷轴20的外表面与弧形槽体的内壁之间是具有特定的设定间距，该设定间距的路径距离至少需要满足预缠绕滤网后的叠堆的滤网厚度。这样，能保证第一卷轴20或第二卷轴30上的滤网不会与第一卷轴安装空间11或第二卷 轴安装空间12接触，从而使滤网可以顺畅地移动。
结合图7和图8所示，在本公开实施例中，以第二卷轴30的主动转动带动第一卷轴20从动转动为例，滤网的第一侧边安装在第一安装结构21上，并且滤网沿第一卷轴20的外圆周进行部分预缠绕。可选地，第一安装结构21包括开设在第一卷轴20表面的第一条形槽211和设置在第一条形槽211内的第一夹持条212，滤网的第一侧边通过第一夹持条212夹持在第一条形槽211内。可选地，第一安装结构21包括粘结部，滤网的第一侧边也可以直接通过粘结的方式固定在第一卷轴20的轴向表面。
在本公开实施例中，第一条形槽211为沿其第一卷轴20的轴向表面开设的通槽，第一夹持条212的长度与第一条形槽211的长度匹配。在安装滤网的情况下，首先将滤网的侧边放入至第一条形槽211内，再将第一夹持条212放入至第一条形槽211。这样，能使滤网夹持固定在第一条形槽211内。在拆卸滤网的情况下，将第一夹持条212从第一条形槽211内扣下即可。
结合图7和图8所示，在本公开实施例中，第二卷轴30沿其轴向的表面上设置有第二安装结构31，可选地，第二安装结构31包括开设在第二卷轴30表面的第二条形槽311和设置在第二条形槽311内的第二夹持条312，滤网的第二侧边通过第二夹持条312夹持在第二条形槽311内。可选地，第二安装结构31包括粘结部，滤网的第二侧边也可以直接通过粘结的方式固定第二卷轴30的轴向表面。这里，滤网安装在第二安装结构31上的形式与滤网安装在第一安装结构21上的形式相同，不再赘述。
其中，在上述实施例中，滤网一侧边通过夹持的方式固定，另一侧也可以采用粘结的方式固定。
结合图7和图8所示，在一些实施例中，第一卷轴20包括：第一轴杆22，其轴向中部至少部分为中空通腔；第一轴套23，一端插接固定在第一轴杆22的第一端，另一端转动连接在第一卷轴安装空间11的第一端；弹性复位组件24，一端插接固定在第一轴杆22的第二端，另一端固定连接在第一卷轴安装空间11的第二端。
在本公开实施例中，第一轴杆22其轴向中部至少部分为中空通腔，能使弹性复位组件24伸入即可。这里，在第一轴杆22的表面开设有第一条形槽211。其中，第一条形槽211的两端通过第一轴套23和弹性复位组件24进行封堵。
在本公开实施例中，第一卷轴20为从动转动，第二卷轴30为主动转动。其中，第一卷轴20包括第一轴杆22和设置在两端的第一轴套23和弹性复位组件24。第一轴套23转动连接在第一卷轴安装空间11的第一端，用于第一轴杆22的转动。弹性复位组件24固定连接在第一卷轴安装空间11的第二端，用于第一轴杆22做复位转动。比如在第二卷轴30转动的情况下，滤网会随之移动，第一卷轴20也会随之转动，待滤网清扫完毕后，第二卷轴30反向转动，此时第一卷轴20通过弹性复位组件24做复位转动，使得滤网能恢复到原来位置。
在上述实施例中，第一卷轴20通过弹性复位组件24进行滤网的收卷动作，第二卷轴30进行滤网的展开动作。
结合图9和图10所示，为了便于弹性复位组件24进行滤网的收卷动作，在一些实施例中，弹性复位组件24包括：连接座241，插接在第一轴杆22的第二端，连接座241的中部设置有插孔242；销轴243，一端通过插孔242伸入至第一轴杆22的中空通腔内，另一端用于固定连接在第一卷轴安装空间11的第二端；扭簧244，套设于销轴243，且一端与连接座241固定连接，另一端与销轴243位于中空通腔的端部固定连接。
在本公开实施例中，弹性复位组件24包括连接座241、销轴243和扭簧244。由于第一轴杆22其轴向中部为中空通腔，插接固定好连接座241后，销轴243能通过插孔242伸入到中空通腔内，将扭簧244套接在销轴243上，扭簧244一端与连接座241固定连接，扭簧244的另一端与销轴243位于中空通腔的端部固定连接。
在第二卷轴30带动第一卷轴20转动的情况下，第一轴杆22带动弹性复位组件24中的连接座241转动，使得连接座241在销轴243上转动，由于扭簧244一端固定连接在连接座241上，扭簧244另一端固定连接销轴243上，连接座241与销轴243发生相对转动，从而使扭簧244扭转弹性变形产生弹力；在第二卷轴30反向转动的情况下，通过扭簧244的弹力迫使第一轴杆22转回到原始位置。
结合图10所示，在一些实施例中，销轴243的轴向长度大于扭簧244的轴向长度，其中，销轴243位于中空通腔的端部开设有固定槽247，扭簧244的另一端固定连接于固定槽247。
在本公开实施中，可以根据第一轴杆22所需要的扭矩或旋转力，改变扭簧244的长度或者扭簧244的簧圈之间的间距。这里，扭簧244的第一端部固定在连接座241上，扭簧244的第二端部固定在销轴243上。其中，在销轴243的端部开设有固定槽247，扭簧244的轴向端部插入固定在固定槽247内。比如扭簧244的端部为钢丝，钢丝固定插接在固定槽247内。当第一轴杆22绕着扭簧244中心逆向旋转时，扭簧244的两端将会产生扭矩或旋转力。
结合图10所示，在一些实施例中，销轴243位于连接座241侧设置有连接槽口245，弹性复位组件24还包括：固定板246，一端插接在连接槽口245上，另一端固定连接在第一卷轴安装空间11的第二端。
在本公开实施中，为方便固定销轴243，在销轴243上设置有连接槽口245，该槽口为方形槽口。这样，在固定板246插入到连接槽口245上时，能防止固定板246与销轴243之间发生转动。其中固定板246位于第一卷轴安装空间11的第二端的一侧设置于固定孔，通过螺钉穿过固定孔将固定板246固定在第一卷轴安装空间11的第二端。
结合图7和图8所示，在一些实施例中，第二卷轴30包括：第二轴杆32；传动件33，一端插接固定在第二轴杆32的第一端，另一端与第二卷轴安装空间12的驱动端连接；第二轴套34，一端插接固定在第二轴杆32的第二端，另一端转动连接在第二卷轴安装空间12的转动端。
在本公开实施例中，第二轴杆32为实心杆，在第二轴杆32的表面开设有第二条 形槽311。其中，第二条形槽311的两端通过第二轴套34和传动件33进行封堵。并且在第二轴套34和传动件33能够通过螺钉连接的方式固定在第二轴杆32的两端。
在本公开实施例中，第二卷轴30为主动转动。其中，第二卷轴30包括第二轴杆32和设置在两端的第二轴套34和传动件33。第二轴套34转动连接在第二卷轴安装空间12的转动端，用于第二轴杆32的转动。传动件33与第二卷轴安装空间12的驱动端连接，用于主动转动第二轴杆32。可选地，在第二卷轴安装空间12的驱动端侧设置有驱动电机，驱动电机与传动件33连接。
在上述实施例中，第一轴套23和第二轴套34均采用自润滑材质制成，这样，能减小各卷轴与连接部之间的摩擦力。
结合图11至图14所示，在一些实施例中，集尘装置40包括：集尘盒41，设置于支撑板14的第一支撑面141下方，集尘盒41具有朝向第一支撑面141侧的敞口；其中，毛刷组件42设置于集尘盒41内，位于敞口的下方，毛刷组件42的刷毛从敞口露出，在集尘盒41的敞口处设置有滤网经过的支撑板14，以对滤网提供有效的支撑，防止滤网变形。在集尘盒41设置有毛刷组件42，并且毛刷组件42的刷毛与滤网抵接。这样，在进行清扫滤网的情况下，第一支撑面141能对滤网提供有效的支撑，避免与毛刷组件42的刷毛接触后产生过度变形，从而使毛刷组件42的刷毛能充分的与滤网接触，便于使清扫滤网的灰尘和杂质，进而提高除尘结构的清扫效果。
结合图14所示，在一些实施例中，支撑板14的第一支撑面141为拱起面结构或平面结构，其中，支撑板14的第一支撑面141还设置有支撑凸起142，以支撑起经过第一支撑面141的滤网。
在本公开实施例中，由于支撑板14的第一支撑面141能支撑起滤网，因此，第一支撑面141为拱起面结构或平面结构。这里，拱起面结构指的是支撑板14为弧形板，平面结构指的是支撑板14为平板。其中，滤网与第一支撑面141抵接，同时毛刷组件42的刷毛也是与滤网抵接，这样第一支撑面141能保证毛刷组件42不会使滤网变形。在此基础上，在第一支撑面141还设置有支撑凸起142，该支撑凸起142在第一支撑面141上具有一定的高度。因此，该位置处的滤网与第一支撑面141分离。这样，能使毛刷组件42的刷毛穿过滤网的过滤孔，对滤网进一步清洁。
结合图14所示，在一些实施例中，第一支撑面141还设置有避让槽143，位于毛刷组件42的移动路径侧，毛刷组件42的刷毛穿过滤网能进入避让槽143。这样，不仅能使毛刷组件42的刷毛与滤网充分接触，还能减弱毛刷组件42的受力，避免毛刷组件42的刷毛长时间受到第一支撑面141的挤压，导致毛刷组件42的刷毛弯曲。
在一些实施例中，支撑板14的第一支撑面141侧边为弧形边。能防止支撑板14的侧边刮破滤网。这里，滤网是经过整个第一支撑面141，但是滤网是如果以绕设的形式在支撑板14上，即滤网是能与第一支撑面141侧边抵接的。为了防止支撑板14刮破滤网，在第一支撑面141的边缘处为圆角结构，进而不仅能减小侧边对滤网的阻力，还能防止支撑板14的侧边刮破滤网。
结合图14和图15所示，在一些实施例中，集尘装置40还包括：清扫结构43，设置于集尘盒41内和/或集尘盒41的开口处，用于清理毛刷组件42中的刷毛。
在本公开实施例中，在毛刷组件42清理滤网灰尘的过程中，虽然能将滤网的灰尘清理掉。但是，毛刷组件42的刷毛上不可避免的会存在残留灰尘和杂质，在长时间的使用下，清扫效果会变差，甚至失去清扫能力。因此通过清扫结构43清理毛刷组件42中刷毛的灰尘，提高清扫效果。可选地，可以在集尘盒41内设置有清扫结构43。可选地，可以在集尘盒41的开口处设置有清扫结构43。可选地，可以在集尘盒41内和集尘盒41的开口处均设置有清扫结构43
结合图14和图15所示，在一些实施例中，清扫结构43包括：第一清扫部431，设置于集尘盒41内，位于支撑板14的第一支撑面141的下方，第一清扫部431具有与毛刷组件42的刷毛抵接的第一清扫边。
在本公开实施例中，第一清扫部431与支撑板14是相对设置，第一清扫部431与第一支撑面141的间距是小于毛刷组件42的直径的。因此，在毛刷组件42转动的过程中，不仅能与滤网侧抵接，还能与第一清扫部431的第一清扫边抵接。这样，毛刷组件42清理滤网的灰尘后，经过第一清扫部431的第一清扫边清扫毛刷组件42上剩余的灰尘。
可选地，结合图15所示，第一清扫部431包括一个或多个依次相连设置的竖向板4311，其中，各竖向板4311的竖向面与毛刷组件42的轴心具有夹角，且各竖向板4311朝向毛刷组件42侧边为锯齿状结构，多个锯齿状结构组成第一清扫边。其中，为了使清扫效果更好，多个竖向板4311倾斜的设置在集尘盒41的底部，在竖向板4311上设置有锯齿状结构，该锯齿状结构也为倾斜设置。这样，能使锯齿状结构设置的更加密集，进而清扫的更干净。
结合图14和图15所示，在一些实施例中，清扫结构43还包括：第二清扫部432，设置于集尘盒41的敞口侧，位于支撑板14的侧方，第二清扫部432具有与毛刷组件42的刷毛抵接的第二清扫边。
在本公开实施例中，在毛刷组件42转动的过程中，毛刷组件42首先将第一支撑面141的滤网进行清扫，然后毛刷组件42经过第二清扫部432，第二清扫部432对毛刷组件42进行一次粗清理，可以将毛刷组件42上较大的灰尘颗粒清理掉；然后毛刷组件42再经过第一清扫部431，第一清扫部431对毛刷组件42进行一次细清理，可以将毛刷组件42上剩余的细小的灰尘颗粒清理掉。这样，毛刷组件42经过第二清扫部432和第一清扫部431的清理，能将毛刷组件42的大部分灰尘、杂质处理掉，保证干净的毛刷组件42清理滤网。
可选地，第二清扫部432包括沿集尘盒41的敞口向支撑板14侧延伸的延长边4321，延长边4321的侧边为锯齿状结构，连续的锯齿状结构组成第二清扫边。其中，该延长边4321朝向支撑板14侧，并且向集尘盒41的盒底侧弯曲，这样，能保证毛刷组件42的灰尘、杂质能都进入到集尘盒41，避免落到集尘盒41外侧。
在一些实施例中，集尘盒41的内壁贴附抗菌材料的贴纸或涂层。这样，方便清理集尘盒41内收集的灰尘，也能防止集尘盒41内的灰尘产生细菌流入到室内。
在本公开实施例中，抗菌材料包括无机抗菌剂、有机(合成类)抗菌剂、天然有机抗菌剂、高分子类抗菌剂或复合抗菌剂等，通过上述中的一种或多种抗菌剂制作成贴纸，并将该贴纸贴敷于集尘盒41的内壁。
在本公开实施例中，也可以通过上述中的一种或多种抗菌剂制作成涂层，并将该涂层涂敷于集尘盒41的内壁。
可选地，可以在集尘盒41内设置有相应的传感器，待检测到集尘盒41内的灰尘已经达到设定阈值的情况下，清理集尘盒41。
结合图16和图17所示，在一些实施例中，用于空调滤网的自清扫结构还包括：驱动装置50，设置于滤网安装架10侧方，通过传动齿轮组60带动第二卷轴30和毛刷组件42同步转动。
在本公开实施例中，第二卷轴30为主动转动，在第二卷轴30侧设置有驱动装置50，该驱动装置50可以采用能正转和反转的驱动电机。这样，在需要清洁滤网的情况下，驱动电机正转，通过第二卷轴30展开滤网；在需要清洁滤网结束后，驱动电机反转，通过一卷轴20和第二卷轴30收卷滤网。这里，驱动装置50能通过传动齿轮组60带动第二卷轴30和毛刷组件42同步转动。这样，能保证只要滤网移动，就可以实现毛刷组件42清理滤网。
结合图18所示，在一些实施例中，传动齿轮组60包括：第一齿轮61，设置于第二卷轴安装空间12侧，连接在第二卷轴30的端部；第二齿轮62，设置于集尘装置40侧，连接在毛刷组件42的端部；第二齿轮62，靠近第一齿轮61和第二齿轮62设置，且分别与第一齿轮61和第二齿轮62啮合；第四齿轮64，设置于滤网安装架10侧，与第三齿轮63啮合；其中，第四齿轮64与驱动装置50的驱动端连接。
在本公开实施例中，为能使第二卷轴30和毛刷组件42同步转动，传动齿轮组60包括多个齿轮组成，包括第一齿轮61、第二齿轮62、第三齿轮63和第四齿轮64。其中，第一齿轮61和第二齿轮62为第二卷轴30和毛刷组件42的直接齿轮，第三齿轮63为同步传动齿轮，第四齿轮64为驱动齿轮。通过第四齿轮64与第三齿轮63啮合转动，第三齿轮63能同时带动第一齿轮61和第二齿轮62转动，从而使第二卷轴30和毛刷组件42同步转动。
在一些实施例中，第一齿轮61、第二齿轮62和第四齿轮64的直径均小于第三齿轮63的直径。这样，驱动装置50更加方便的通过第三齿轮63控制第一齿轮61和第二齿轮62的转动角度，进而控制滤网的移动速度。此外，驱动装置50安装的位置位置更多，无需设定在特定的位置，影响其他部件的使用。比如驱动装置50安装在集尘装置40侧，可能会影响用户清理灰尘等。
在本公开实施例中，为了使驱动装置50能通过传动齿轮组60带动滤网移动，其在齿轮传动侧的动力矩和阻力矩应该满足如下条件：
M1*Z2/Z1＞Mn*Z2/Z4+Mb*Z2/Z3
其中，M1为驱动装置50的扭矩，Mn为卷轴的阻力矩，Mb为毛刷组件42的阻力矩，Z1为第四齿轮64的直径，Z2为第三齿轮63的直径，Z3为第二齿轮62的直径，Z4为第一齿轮61的直径。
在本公开实施例中，卷轴侧的阻力矩应该满足如下条件：
Mn＝R4*Fn
其中，R4为第二卷轴30的半径，Fn为第二卷轴30的阻力矩。
在本公开实施例中，第二卷轴30的阻力矩的应该满足如下条件：
Fn＝{K*S/(R5*R5)+f2+f3}
其中，K为扭簧244的刚度，S为滤网移动的距离，R5为第一卷轴20的半径，f2为滤网104与毛刷组件42的阻力，f3为滤网104与滤网安装架10的阻力。
在本公开实施例中，毛刷组件42的阻力矩应该满足如下条件：
Mb＝R3*f2
其中，R3为毛刷组件42的半径。
结合上述实施例，齿轮传动侧的动力矩与阻力矩的比例取值范围为[1.1，1.9]，即保证动力矩大于阻力矩即可。可选地，该动力矩与阻力矩的比例取值范围为[1.2，1.8]。可选地，该动力矩与阻力矩的比例取值范围为[1.3，1.7]。可选地，该动力矩与阻力矩的比例取值范围为[1.4，1.6]。可选地，该设定夹角的取值范围为1.5。
在一具体应用中，动力矩与阻力矩的比例取值为1.5。当然，在其他应用中，动力矩与阻力矩的比例取值范围可以选自[1.1，1.9]内的任意比例，依据实际需要设置即可。
在上述实施例中，由于滤网很薄，并且滤网在第一卷轴20和第一卷轴20的缠绕层数有限，因此，忽略滤网缠绕过程中两个卷轴总直径尺寸的变化。
本公开实施例还提供一种空调器，包括：空调器本体，具有进风口；如前述实施例所述的用于空调滤网的自清扫结构，自清扫结构的滤网安装架10设置于进风口的下方，滤网安装架10上设置有滤网。
参照上述实施例，该空调器包括上述的用于空调滤网的自清扫结构，参照上述实施例，因此至少具有上述实施例的技术方案所带来的有益效果，在此不再一一赘述。
以上描述和附图充分地示出了本公开的实施例，以使本领域的技术人员能够实践它们。其他实施例可以包括结构的以及其他的改变。实施例仅代表可能的变化。除非明确要求，否则单独的部件和功能是可选的，并且操作的顺序可以变化。一些实施例的部分和特征可以被包括在或替换其他实施例的部分和特征。本公开的实施例并不局限于上面已经描述并在附图中示出的结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
