请参阅图1和图2，本发明实施方式的空调器10形成有进风口11。空调器10还包括 靠近进风口11设置的用于净化空气的净化滤网12。净化滤网12在进风口11的正投影与进风口11的面积之比大于30％。
本发明实施方式的空调器10，在靠近进风口11的位置设置有用于净化空气的净化滤网12，且净化滤网12在进风口11的正投影与进风口11的面积之比大于30％，如此，空调器10不仅能够调节室内温度，同时能够净化室内空气，并保证制冷制热性能基本不变。
在某些实施方式中，空调器10形成有位于进风口11下游的风道13。空调器10还包括设置在风道13内的风机14和换热器15。风机14用于建立气流，换热器15用于实现气流的换热以达到温度调节的目的。风道13形成有位于下游的出风口16。
在空调器10调节温度的过程中，室内空气由进风口11进入空调器10的室内机10a，经过换热器15时，与换热器15的铝箔和铜管发生热交换，从而实现升温或降温，发挥调节室内温度的作用。空气经过换热器15后，会经过风道13中的风机14，风机14用于驱动气流流经换热器15，从而发生热交换。当气流流经风机14后，从出风口16排出，完成一个温度调节循环。在这一循环过程中，气流温度在换热器15前被设置在风道13内的感温探头18检测，并由空调器10的单片机判断当前气流温度是否达到设定温度，以及计算当前气流温度与设定温度之间的差值。空调器10的单片机根据该差值发出相应的驱动信号驱动压缩机和风机14工作，从而使得室内的实际温度不断趋近于用户设置的室内理想温度(即设定温度)。
在一个实施方式中，净化滤网12设置在进风口11处(如图1所示)。更具体地，净化滤网12设置在进风口11前(按气流的方向判定，气流先经过的位置为前)。
当空调器10工作时，空气在风机14的驱动下，在进入空调器10的室内机10a之前，会经过净化滤网12，如此，实现了空气净化功能。
在另一个实施方式中，净化滤网12设置在进风口11和换热器15之间(如图3和图4所示)。
当空调器10工作时，空气在风机14的驱动下，在流经换热器15之前，会经过净化滤网12，如此，实现了空气净化功能。
当然，在其他实施方式中，净化滤网12还可以部分设置在进风口11处，部分设置在进风口11和换热器15之间(如图5所示)，这里不作限制。
可以理解，当净化滤网12在进风口11的正投影的面积越大时，空气进入风道13时受到的阻力越大，引起空调器10的风量衰减越大。在本发明实施方式的空调器10中，净化滤网12在进风口11的正投影与进风口11的面积之比只需大于30％，即可较好地实现空气净化功能。如此，降低了风阻，减小了由于净化滤网12引起的空调器10的风量衰减，从而避免了对空调器10的制冷制热的基本性能造成影响。
在某些实施方式中，净化滤网12呈平板状或曲面状。
例如，图1所示的空调器10的净化滤网12呈平板状，图3-5所示的空调器10的净化滤网12呈曲面状。可以理解，当净化滤网12呈曲面状时，同样应当满足净化滤网12在进风口11的正投影与进风口11的面积之比大于30％，而不是按照净化滤网12的实际平展面积与进风口11的面积之比大于30％来计算。
在一个实施方式中，当净化滤网12呈平板状时，净化滤网12平行于进风口11。也即是说，净化滤网12与进风口11相对的表面平行于进风口11与净化滤网12相对的表面。如此，进风口11各处进风和净化效果均匀，净化滤网12也容易安装。净化滤网12与进风口11之间的距离可以根据实际情况进行确定，以能达到最佳的空气净化效果和对空调器10的风量降低尽可能小为准。
请参阅图6-13，在某些实施方式中，进风口11呈矩形。净化滤网12包括沿进风口11的长度或宽度方向延伸直跨或斜跨进风口11的至少一个带状子滤网。
需要指出是，图6-13为净化滤网12的俯视图，即净化滤网12在进风口11的正投影视图。在此基础上，净化滤网12可以呈平板状或曲面状，这里不作限制。
具体地，图6-9为带状子滤网沿进风口11的长度方向延伸直跨进风口11的四个实施例。其中，A1-A3中至少有一个为带状子滤网，A4-A5中至少有一个为带状子滤网，A6-A9中至少有一个为带状子滤网，A10-A14中至少有一个为带状子滤网。各带状子滤网的分布位置和个数不作限制。例如，可以是A2、A5、A6、A8、A11、A13为带状子滤网，A1、A3、A4、A7、A9、A10、A12、A14为空白区域。
图10-12为带状子滤网沿进风口11的宽度方向延伸直跨进风口11的三个实施例。其中，B1-B5中至少有一个为带状子滤网，B6-B7中至少有一个为带状子滤网，B8-B14中至少有一个为带状子滤网。各带状子滤网的分布位置和个数不作限制。例如，可以是B1、B3、B5、B7、B9、B11、B13为带状子滤网，B2、B4、B6、B8、B10、B12、B14为空白区域。
图13为带状子滤网沿进风口11的宽度方向延伸斜跨进风口11的实施例。其中，C1-C8中至少有一个为带状子滤网。带状子滤网的分布位置和个数不作限制。例如，可以是C2、C4、C6、C8为带状子滤网，C1、C3、C5、C7为空白区域。
同理，带状子滤网可以沿进风口11的长度方向延伸斜跨进风口11，在此不再举例说明。
在某些实施方式中，带状子滤网包括多个且间隔设置。
例如，在图8-10中，A6、A8为带状子滤网，A6、A8间隔设置；A11、A13为带状子滤网，A11、A13间隔设置；B1、B3、B5为带状子滤网，B1、B3、B5间隔设置。多个带状子滤网的宽度可以相等或不等。多个带状子滤网间隔的距离可以相等或不等。也即是说，A6-A14、B1-B5的宽度相互之间可以相等或不等。
在一个实施方式中，多个带状子滤网的宽度相等。多个带状子滤网间隔的距离相等。
如此，净化滤网12容易制造，空气净化效果均匀，且进风区域均匀分布在进风口11，空气进入风道13后与换热器15换热效率高，不会存在换热器15的一侧过度工作的现象，有利于延长空调器10的使用寿命。
可以理解，即使多个带状子滤网间隔设置，导致进风口11的部分面积未被净化滤网12覆盖，但是通过合理调校各子滤网覆盖进风口11的位置、面积和块数，空调器10整体的空气净化效果仍然能达到较佳。具体地，可以通过合理布置不同带状子滤网的位置、面积和块数等(例如，将各子滤网配置在其能发挥最佳过滤效果的风速上，同时考虑到对空调器10的风量降低尽可能小)，如此，以最小的净化滤网12的面积，实现最佳的空气净化效果、对空调器10的风量降低尽可能小和保证空调器10的制冷制热性能基本不变。
请参阅图14，在某些实施方式中，净化滤网12在进风口11的正投影与进风口11的面积之比为100％。
也即是说，净化滤网12在进风口11的正投影完全覆盖进风口11。
需要指出是，图14为净化滤网12的俯视图，即净化滤网12在进风口11的正投影视图。在此基础上，净化滤网12可以呈平板状或曲面状，这里不作限制。
由于在进风口11大面积使用了净化滤网12，空气进入换热器15前基本都需要经过净化滤网12，空调器10具有明显的空气净化效果，可以达到较高的CADR(clean air delivery rate，洁净空气量)数值。
请参阅图15-17，在某些实施方式中，净化滤网12为形成有切口的一体结构且净化滤网12的外轮廓与进风口11配合。
如此，净化滤网12为一体结构，容易安装。
需要指出是，图15-17为净化滤网12的俯视图，即净化滤网12在进风口11的正投影视图。在此基础上，净化滤网12可以呈平板状或曲面状，这里不作限制。
具体地，净化滤网12整体为不规则的形状，净化滤网12可以边缘形成有切口(如图15中的D1和图17中的D3)，或者净化滤网12中间形成有切口(如图16中的D2)等，切口的形状可以为三角形、长方形、平行四边形、圆形或不规则形状等。净化滤网12的外轮廓与进风口11配合可以是指净化滤网12的大小和弯曲弧度与进风口11的结构进行配合，以便安装。
在一个实施方式中，多个切口均匀分布(如图17所示)。
如此，净化滤网12容易制造，空气净化效果均匀，且进风区域均匀分布在进风口11，空气进入风道13后与换热器15换热效率高，不会存在换热器15的一侧过度工作的现象，有利于延长空调器10的使用寿命。
需要指出的是，本发明上述各实施方式的净化滤网12的布置方法可以相互组合，例如，净化滤网12可以包含多个子滤网，部分子滤网为带状，部分子滤网为带有切口的结构，甚至可以为不规则形状或任意形状；各子滤网可以沿进风口11的长度方向布置，也可以沿进风口11的宽度方向布置；净化滤网12可以全覆盖进风口11，也可以部分覆盖进风口11，只需满足净化滤网12在进风口11的正投影与进风口11的面积之比大于30％即可。
请再次参阅图1，在某些实施方式中，空调器10还包括设置在风道13内的离子发生器17。离子发生器17用于产生正离子和/或负离子。
具体地，离子发生器17利用高压变压器将工频电压升压到所需电压的方法产生离子，并释放到周围的环境中，以净化空气。
离子发生器17可以为负离子发生器、或者正离子发生器、或者正负离子发生器。可以理解，负离子发生器用于产生负离子，正离子发生器用于产生正离子，正负离子发生器用于产生正离子和负离子。离子发生器17的种类可以根据实际情况进行选择。
离子发生器17产生正离子和/或负离子，一方面可以杀灭空气中的病菌，另一方面可以使得空气中的尘埃或颗粒带电，从而更容易吸附在净化滤网12上。此外，空气中的尘埃或颗粒带电后，即使通过过滤孔径远大于自身尺寸的净化滤网12(特别是通过带相反电荷的净化滤网12)，也会以非常高的效率被吸附。如此，净化滤网12的过滤孔径可以远大于尘埃或颗粒的直径，从而大幅较低净化滤网12的通过风阻，保证空调器10自身的制冷制热性能和风量基本不受影响。
在一个实施方式中，离子发生器17可以与净化滤网12搭配使用。例如，当离子发生器17为负离子发生器时，净化滤网12可以为带正电荷的净化滤网12。如此，离子发生器17产生负离子，使得空气中的尘埃或颗粒带负电，从而更容易的吸附在带正电荷的净化滤网12上，进而提升CADR数值。
在某些实施方式中，离子发生器17设置在出风口16处。
如此，离子发生器17通过产生正离子和/或负离子杀灭空气中的病菌和净化空气。
当然，在其他实施方式中，离子发生器17还可以设置在空调器10的室内机10a的其他位置，以达到杀灭病菌和净化空气的作用。
在某些实施方式中，净化滤网12包括静电驻极滤网或有源静电吸尘滤网。
具体地，静电驻极滤网利用电荷的静电力作用捕集尘粒。静电驻极滤网采用静电驻极材料制作而成，该材料具备优异的介电性能，如高体电阻和表面电阻，高介电击穿强度，低吸湿性和透气率等，能够在无外界电源输入的情况下长期存储空间电荷或偶极电荷，从而发挥利用电荷的静电力捕集空气中尘埃粒子的功能。
本发明实施方式中的静电驻极材料主要以高聚物为主，包括聚丙烯、聚四氟乙烯、六 氟乙烯/聚四氟乙烯共聚物、聚三氟乙烯、聚丙烯(共混)及聚酯等。
具体地，有源静电吸尘滤网利用库仑力捕集空气中的尘粒。有源静电吸尘滤网由吸尘电极组成，具体排布方式为正负电极交错排布，从而形成多个电场区域，利用库仑力捕集空气中的尘埃粒子。
需要指出的是，当净化滤网12包括静电驻极滤网或有源静电吸尘滤网时，静电驻极滤网和有源静电吸尘滤网均可拆卸清洗或更换。
在一个实施方式中，静电驻极滤网或有源静电吸尘滤网可以与离子发生器17结合使用。
可以理解，风道13内设置有离子发生器17时，离子发生器17向空气中发散正离子和/或负离子，使得尘埃或颗粒带电，包括有静电驻极滤网或有源静电吸尘滤网的净化滤网12的空气净化功能将进一步提升，同时有利于降低静电驻极材料和吸尘电极的使用强度，降低净化滤网12的通过风阻。
