本发明实施例的空气净化装置：进风口1，换热器2，感温探头3，出风口4，风道5，导风板6，红外传感器7，离子发生器8。
相关技术中的空气净化装置：主机1’，进风口2’，换热器3’，风道4’，出风口5’，感温探头6’。
具体实施方式
如图7和图8所示，在相关技术中，空气净化设备用于净化空气、制热、制冷、送风等等。图1给出了常用的空调系统结构图。1’为常见的分体式空调室内机，一般的功能是以制冷或制热状态工作，从而调节室内的空气温度。在调节温度的过程中，室内空气由进风口2’进入空调室内机，经过换热器3’时，同换热器铝箔和铜管发生热交换，从而实现加温或降温，发挥调节空气温度的作用。空气流经换热器3’后，会经过风机风道系统4’中的风轮，在空调系统中，风机风道系统4’的主要功能是驱动气流流经换热器3’，从而发生热交换。当气流流经风轮后，会从出风口5’排出，完成一个温度调节循环。在这一循环过程中，气流温度会在换热器前被感温探头6’检测，并由空调内的单片机判定是否达到设定温度和与设定温度的差值，并由这一差值发出压缩机和风机的驱动信号，使室内实际温度不断趋近于用户设计的室内理想温度。
上述过程即为现有空气温度调节的原理，但现有空调仅能够调节室内空气温度。事实上，室内空气质量正越来越成为一个重要的问题，但现有空调技术无法对室内空气进行净化和消毒。
本发明涉及一种室内空气净化和消毒方法，目的是在使用空气调节系统调节室内温度的同时，能够同时对室内空气进行净化和消毒处理。在我国和其他一些主要发展中国家，空气质量长期不佳，由此给健康带来的影响不可忽视；同时，室内空气由于温湿度适宜，往往成为各种病菌滋生的温床。因此，本发明提出了一种适用于家用空调的室内空气净化和消毒方法，使得空调不仅能够控制室内温度，同时能够对室内空气进行净化和消毒。本发明在室内空气调节领域有较为广泛的应用价值。
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
如图1，根据本发明实施例的空气净化装置的杀菌方法，所述空气净化装置包括用于生成臭氧的杀菌元件和用于驱动臭氧在间室内流通的气流驱动件。所述杀菌方法包括以下步骤：
S1，检测人员与间室之间的距离L，可以通过检测人员与间室之间的距离L确定人员是否离开间室，也可以通过检测人员与间室之间的距离L确定人员是否将要回到间室。
S2，在检测到人员离开间室后所述杀菌元件产生臭氧并通过气流驱动件将臭氧送往间室内，臭氧具有杀菌的作用，可以灭杀间室内的细菌等，但是，高浓度(例如不小于0.3mg/m3)的臭氧可能会对人体产生影响，因此，需要在人员离开间室后对间室内进行杀菌。通过检测人员离开间室后产生臭氧，可以避免臭氧对人体产生的伤害。
S3，持续检测人员与间室之间的距离L，并监测人员是否将要回到间室，在利用臭氧杀菌运行的过程中，距离L的检测是持续进行的，以避免人员将要回到间室后，间室内的臭氧浓度依然过高。
S4，所述杀菌元件产生臭氧一段时间后或在检测到人员将要回到间室时杀菌元件停止产生臭氧。换言之，杀菌元件产生臭氧一端时间、人员将要回到间室这些条件是或的关系。也就是说，杀菌元件产生臭氧、人员将要回到间室这些条件中的至少一个满足时杀菌元件就停止产生臭氧。具体而言，在没有人员将要回到间室的条件下，如果杀菌元件产生臭氧一段时间后，间室内的杀菌目的已经完成，此时基于节能等要求，可以使杀菌元件不产生臭氧；而在检测到人员将要回到间室时，不论杀菌元件产生臭氧是否达到了足够的时间，均使杀菌元件不产生臭氧，以避免对人员的伤害。
根据本发明实施例的空气净化装置的杀菌方法，可以通过杀菌元件产生臭氧来进行杀菌，而且还可以避免对人员产生伤害，可以有效地灭杀细菌并保证人员安全。
另外，需要说明的是，在一些情况下，并非人员离开间室后就产生臭氧，也并非只有在产生臭氧一端时间、人员将要回到间室中的一个条件满足就停止臭氧，也可以基于其它因素选择是否启动臭氧杀菌，例如，室内存在宠物、室内存在不适于臭氧环境的物品等情况时不会产生臭氧进行杀菌，又例如，在检测到人员将要回到间室内时，根据使用者的选择决定是否停止产生臭氧，举例而言，在通过距离L检测到人员将要回到间室，但是仅仅是距离L检测的结果，使用者可以根据实际选择是否停止产生臭氧，当然，应当建立相应的保护机制，例如降低间室内的臭氧浓度、提供报警信号等等，以保证人员安全。而且，杀菌方法中，也并非是人员离开间室后就产生臭氧，可以选择人员离开间室后经过一端时间后启动臭氧杀菌。
本领域技术人员可以理解的是，本发明中提及的是杀菌的方法，并非是只要人员离开间室就产生臭氧，而是根据实际情况进行选择，例如人为决定是否运行本发明中杀菌的方法、或每间隔一段时间(例如一周、几天等)运行杀菌等等。
在本发明的一些实施例中，在所述S2中，当检测到所述距离L不小于下阈值H1时判定人员离开间室。也就是说，在需要杀菌时，如果检测到距离L≥H1则运行杀菌元件产生 臭氧。
在所述S3中，当检测到所述距离L不大于上阈值H2时判定人员将要回到间室。也就是说，在人员离开后，且处于杀菌的状态下，如果检测到距离L≤H2，则杀菌元件停止产生臭氧。
另外，下阈值H1不大于上阈值H2(H1≤H2)。
其中，下阈值H1与上阈值H2可以相同，也就是，距离L小于阈值则停止产生臭氧；距离L大于阈值则产生臭氧。
另外，下阈值H1与上阈值H2可以不相同。
例如，可以为H1＜H2，也就是说，距离小于下阈值H1时不产生臭氧；距离大于H1时产生臭氧；在杀菌元件产生臭氧时，如果距离小于H2则停止产生臭氧(距离小于H1时必然不产生臭氧)。
也可以为H1＞H2，也就是说，距离大于H1时开始产生臭氧；距离不大于H2时如果杀菌元件在产生臭氧，则是杀菌元件停止产生臭氧(距离小于H2时必然不产生臭氧)。
当然，上述描述仅仅是本发明的一个具体实现方式，还可以结合定时控制的方式来进行控制。
另外，在本发明的一些实施例中，所述方法还包括检测人员相对于间室的移动方向，具体而言，就是检测人员是靠近间室还是远离间室。
其中，当检测到所述距离L不大于下阈值H1时杀菌元件不产生臭氧；当检测到所述距离L在下阈值H1和上阈值H2之间时，如果人员朝远离所述间室移动时判定人员离开间室，如果人员朝向所述间室移动时判定人员将要回到间室；当检测到所述距离L不小于上阈值H2时判定人员离开间室，所述下阈值H1不大于所述上阈值H2。
换言之，可以根据距离L与人员的移动方向来确定是否需要产生臭氧。
具体而言，L≤H1时不产生臭氧；L∈(H1，H2)时，如果人员靠近间室则停止产生臭氧，如果人员远离间室则产生臭氧；L≥H2时，产生臭氧。
需要说明的是，本发明上述描述的方案中，处于节点状态时，也就是说L＝H1或L＝H2时，其选择何种控制模式都应该在本发明的保护范围内，本发明上述描述仅仅是为了保证方案的完整性而对节点进行了说明，并非是对本发明保护范围的限制。例如，在前述根据距离L和人员移动方向组合来确定是否产生臭氧时，如果L＝H1，在不同的空气净化装置中，可以选择不产生臭氧或根据人员的移动方向确定是否产生臭氧。这对于本领域技术人员是很容易理解的。
上述阈值的选用主要考虑到臭氧的分解时间，需要满足人员回到间室后，臭氧的浓度已经分解至无法对人员产生伤害，其中，上述阈值H1与H2可能会根据人员的行进速度进 行选择，例如，采用交通工具时，人员的行进速度回比较快，此时可以相应地提高阈值的大小；在步行时，人员的行进速度比较慢，可以相应地降低阈值的大小。
另外，可以根据数据分析来获取人员将要回到间室的时间，例如，根据距离确定人员将要回到间室的时间。
由上述可以看出，阈值H1和H2的选取方式，主要是考虑到了臭氧的分解时间，一般情况下，可以预留半小时来供臭氧杀菌和分解，可选地，上阈值H1和下阈值H2都可以选择在1公里到5公里的范围内。
为了进一步地保证人员的安全，在本发明的一些实施例中，所述S4还包括：在人员与间室之间的距离不大于下阈值H1时，如果所述杀菌元件在产生臭氧则发出室内有臭氧的警告信息，在发出警告信息的同时可以选择控制所述杀菌元件停止产生臭氧，可以通过提示使用者选择是否停止产生臭氧，也可以通过系统自动判定，对于不同的空气净化装置，可以选用不同的方式。
本发明中的间距L可以通过多种方式进行检测确定，例如，人员与间室之间的距离L由卫星定位系统检测确定。当然，还可以通过其他的方式还确定人员与间室之间的距离L，例如，通过雷达、距离传感器等等。
进一步地，人员与间室之间的距离由适于人员随身携带的移动终端与间室之间的距离确定。有利地，可以检测多个点的距离并判断最小值，例如，存在多个使用者共同使用空气净化装置时，可以判定多个使用者均离开间室后产生臭氧。
当然，检测距离的方法很多，本发明不在一一描述，现有技术中可以用作检测人员与间室之间距离的检测方法都可以选用。
本发明第二方面提供了另一种空气净化装置的杀菌方法，所述空气净化装置包括用于生成臭氧的杀菌元件和用于驱动臭氧在间室内流通的气流驱动件。
如图2，所述杀菌方法包括以下步骤：
S1’,接收外部输入的间室内无人的时间段(t1，t2)，可以通过多种方式输入室内无人的时间段，例如，通过移动设备、遥控器、空气净化装置上的按钮等等，从而通过确定室内无人的时间段来确定室内是否有人；
S2’，在达到间室内无人时间段(t1，t2)内后所述杀菌元件产生臭氧并通过气流驱动件将臭氧送往间室内。臭氧具有杀菌的作用，可以灭杀间室内的细菌等，但是，高浓度(例如不小于0.3mg/m3)的臭氧可能会对人体产生影响，因此，需要在人员离开间室后对间室内进行杀菌。通过检测人员离开间室后产生臭氧，可以避免臭氧对人体产生的伤害。
S3’，在达到时间t2-t之前所述杀菌元件停止产生臭氧，其中，t为小于t2-t1的预定值。选择预留的时间t来方便臭氧的分解以及杀菌，可以提高空气净化装置的安全性。
根据本发明实施例的空气净化装置的杀菌方法，可以通过杀菌元件产生臭氧来进行杀菌，而且还可以避免对人员产生伤害，可以有效地灭杀细菌并保证人员安全。
其中，需要说明的是，在达到间室内无人时间段(t1，t2)内后所述杀菌元件产生臭氧并通过气流驱动件将臭氧送往间室内。并非是指知道达到时间点t1就执行杀菌，也可以经过预定时间之后再进行杀菌。
另外，为了方便，时间t不小于半小时。预留半小时以上的时间可以实现臭氧的有效分解，以避免对人体产生伤害。
另外，需要指出的是，还可以在间室内设置传感器，如果检测到室内有人，无论任何情况，不允许运行杀菌。例如，在间室内或空气净化装置上设置红外传感器。
有利地，根据外部的设定时间确定是否杀菌的方法可以结合前述根据距离L确定是否杀菌的方法。可选地，如果设定的室内无人的时间为(t1，t2)，但是，前述检测中距离L的检测结果不适于杀菌，也不应该运行杀菌过程。
在本发明的一些实施例中，所述杀菌元件为离子发生器，所述离子发生器适于低压运行以产生离子且不产生臭氧。有利地，在不需要杀菌元件杀菌时，杀菌元件可以低压运行以避免产生臭氧。
其中，本领域技术人员可以理解的是，离子发生器低压运行时产生离子，而离子发生器高压运行时产生臭氧，这里的低压和高压是相对的，换句话说，离子发生器产生臭氧时就是高压，而离子发生器工作且不产生臭氧时就是低压，对于不同的离子发生器，足够产生臭氧的电压并不相同，因此，高压和低压是相对的，对于不同的离子发生器具有不同的大小。
例如，在一些离子发生器中，在电压在3kv到5kv的范围内时可以产生臭氧，在1kv到2kv之间可以产生离子而不产生臭氧，因此，可以理解地这些离子发生器中，所称的低压在1kv到2kv的范围内，而对应的高压在3kv到5kv的范围内。
当然，如前所述，对于不同的离子发生器，产生臭氧的电压、产生离子不产生臭氧的电压并不相同，因此，对于不同的离子发生器，本发明中的低压和高压需要根据实际情况进行选择。
另外，还需要说明的是，本发明中的产生臭氧是指产生足够灭菌的臭氧，也就是说产生的臭氧浓度应该达到足够灭菌(并非是指杀灭所有细菌)。而一些杀菌元件(离子发生器)低压下可以浓度极其低的臭氧(例如低于0.1ppm甚至低于0.01ppm)，则并不认为杀菌元件产生了臭氧。
本发明第三方面提供了一种空气净化装置，包括：本体、杀菌元件8和控制器。
本体内形成有风道，且风道内设有气流驱动件，风道具有进风口和出风口，气流驱动 件用于驱动气流在风道内由进风口送往出风口以进行间室内的气流循环，气流驱动件驱动气流在风道内流通，具体而言，气流从进风口进入风道内后，从出风口送出，送出室内的气流在经过室内后回流到进气口形成循环。杀菌元件设在本体上，杀菌元件可以用来杀菌，例如，通过杀菌元件产生臭氧，杀菌元件产生的臭氧经过气流驱动件的驱动作用送出风道并送往室内，然后对间室内进行杀菌。控制器与气流驱动件相连，且控制器执行根据前述的空气净化装置的杀菌方法。
根据本发明实施例的空气净化装置，可以通过杀菌元件产生臭氧来进行杀菌，而且还可以避免对人员产生伤害，可以有效地灭杀细菌并保证人员安全。
如图3至图6，在本发明的一些实施例中，杀菌元件为在出风口阵列排布的多个或设在在出风口两侧的多个。例如，在图3中，杀菌元件排布于出风口处并阵列，在图5中，杀菌元件排布于出风口两侧。
图1示出了本发明的一个实施例的空气净化装置。在本发明中，在空调室内机中设置了若干处离子发生器，其可以通过尖端放电或其他形式，向室内空气释放电荷，进一步形成空气离子(正离子或负离子)。这些离子发生器需要设置在空气流速较高的区域，例如风道内、进风口、出风口以及风道在进风口和出风口的延长位置，借助空气流动均匀扩散到室内空气之中，例如在图2给出的发明实例中，多个离子发生器8在空调室内机出风口形成阵列，借助出风口的气流，将空气离子均匀输送至房间内的各位置。
利用离子发生器，对室内空气进行净化和消毒的原理是，如果在离子发生器位置，对空气以较高的电压进行电离，会产生大量臭氧。臭氧对室内空气具备较强的消毒效果，其能够氧化分解细菌内部的酶，破坏细菌、病毒的细胞器和DNA\RNA，使细菌发生通透性畸变，通过以上三种形式，臭氧可以强效杀灭空气中的各类细菌和病毒。此外，臭氧具备强氧化性，还可以和各类有机污染物发生反应，如酚、苯、甲醛等，产生二氧化碳和水。因此采用电离空气的方式形成臭氧，具备强力消毒的作用。此外，离子发生器产生的正负离子，也可以吸附在室内颗粒物上，发挥促进室内空气中的颗粒污染物沉降的功能，从而发挥空气净化效果。
但是，高浓度臭氧会刺激和损害眼睛、呼吸系统等粘膜组织，对人体健康产生负面作用。因此，本发明的重要保护点是：通过手机或其他远程控制方式，在人员不在室内时，利用离子发生器，对空气电离并释放臭氧，从而发挥净化和消毒效果，臭氧很不稳定，在常温下快速分解。因此可以通过以下方式，实施空气净化和消毒。
杀菌的方法包括很多，本发明主要描述例如如下几种杀菌方法：
1、定时设置法：通过手机或其他远程控制方式，设置室内无人时间，空调根据此时间段长度，在保留充足的臭氧分解时间基础上，计算得到臭氧发生时间，并利用室内无人时 间段，完成室内空气的杀菌和消毒。
2、定位设置法：即通过手机或其他方式设置位置，当室内人员远离房屋位置一段距离后，空调开始生成臭氧，当室内人员靠近房屋位置到一定距离后，空调停止产生臭氧，留出充分时间供已产生臭氧分解，完成室内空气的杀菌和消毒。
此外，室内空气净化(颗粒污染物的离子吸附沉降)过程不需臭氧参与，不产生有害气体和物质，此时，离子发生器的离子发生电压不高，仅向空气中释放离子(正离子或负离子)，由于电压不够高，释放的臭氧浓度很低，远达不到损害人体健康的程度，这一空气净化过程无需进行定时或定位设置，在室内有人和无人时都可以进行。图3给出了本发明的另一实施实例，离子发生器位于空调出风口位置的两侧，事实上，离子发生器可以位于空调室内机结构的任何位置。
另外，参照图，本发明的空气净化装置可以为空调器，空气净化装置具有进风口1、换热器2、感温探头3、出风口4、风道5、导风板6、红外传感器7、离子发生器8。
在气流驱动件(风轮)的驱动作用下，空气从进风口进入空气净化装置内，并在与换热器2换热后从出风口4排出，感温探头3可以检测气流和/或换热器的温度，导风板6可以对出风口排出的气流进行导风。
在气流流通过程中，离子发生器8可以产生离子或臭氧，并随着气流送往室内。
本发明的空气净化装置还可以是空气净化器、空调，新风系统等等。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
