具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中 的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请提供一种空调器，如图1所示为本申请提供的空调器的结构示意图。本申请实施例提供的空调器包括室内机100、室外机200和加湿装置。室内机100连接有室内机排水管2，室外机200连接有室外机排水管3。储水盒1分别与室内机排水管2和室外机排水管3相连通，使室内机排水管2和室外机排水管3内的水能够流入到储水盒1内。
如图2所示为本申请提供的空调器中加湿装置的结构示意图，加湿装置包括储水盒1和加湿单元，加湿单元包括加湿体4和风机。储水盒1内设置有加热棒9，加湿体4的一部分位于储水盒1内用于吸收储水盒1内的水，加湿体4的另一部分位于储水盒1外，风机用于从加湿体4的一侧向加湿体4的另一侧送风。具体的，加湿体4可以由湿膜或其他高吸水性材料制成。湿膜的下部浸入储水盒1内的水中，上部伸出储水盒1外部，暴露于空气当中。储水盒1内的水沿湿膜上行，风机正对湿膜位于储水盒1外的部分进行吹风，使气流流经湿膜时得到加湿。其中，加湿体4可选用抑菌湿膜。加热棒9用于给储水盒1内的水进行加热，为环境提供水蒸气。
本申请提供的空调器，通过将室内机排水管和室外机排水管与储水盒相连通，将室内机和室外机的冷凝水和化霜水收集到储水盒内进行存储，以供加湿单元使用，无需频繁的补充加水，大大方便了用户对空调加湿功能的使用，提高了用户体验感。
进一步的，如图2所示，本申请实施例提供的空调器还包括UV光除菌器5，UV光除菌器5的光束照射于加湿体4，进一步降低了加湿器对人体产生的危害。其中，UV光除菌器5可安装于储水盒1的内部或外部，储水盒1内的水随加湿体4上行时经UV光的照射达到除菌效果。UV光除菌器5的光束可照射于加湿体4位于储水盒1外部的部分，以同时对加湿体4上的水以及流经加湿体4的空气进行除菌，
本申请提供的空调器，还包括湿度传感器，湿度传感器与风机通信连 接。具体的，湿度传感器和风机分别与控制器通信连接，湿度传感器用于感测室内环境的当前相对湿度并将检测结果输送到控制器，控制器可根据当前相对湿度判断是否需要加强除湿。例如，当湿度传感器检测到当前相对湿度偏低，则控制风机提高转速，以加快气流带出储水盒1内的水。或者，开启加热棒9对储水盒1内的水进行加热，加快水分从储水盒1内逸散。
进一步的，还包括温度传感器，温度传感器可采用室内机盘管自带的温度传感器；或者直接采用温度传感器与湿度传感器集成于一体的温湿度传感器。控制器可根据当前温度和湿度，对湿度进行湿度补偿，根据计算结果调节风机转速和/或加热棒的输出功率以调节湿度。
如图1所示，本申请实施例中，室外机排水管3和/或室内机排水管2连接有三通阀6，三通阀6的入水口61与室外机排水管3或室内机排水管2相连通，三通阀6的第一出水口62与储水盒1相连通，三通阀6的第二出水口63与外界相连通。
与室外机排水管3上设置的三通阀6为例，三通阀6的入水口61通过室外机排水管3与室外机的集水装置相连通，三通阀6的第一出水口62通过连接水管7与储水盒1相连通。当储水盒1内水量不足时，连通三通阀6的入水口61和第一出水口62，室外机冷凝器的冷凝水和化霜水依次流经室外机排水管3、三通阀6和连接水管7进入到储水盒1内。当储水盒1内的水量足够时，连通三通阀6的入水口61和第二出水口63，使多余的冷凝水或化霜水从第二出水口63排出。其中，第二出水口63可通过管路连通到外界。同理，室内机排水管2与三通阀6和储水盒1之间的连接关系与上述室外机排水管3与三通阀6和储水盒1之间的连接关系相同，在此不在赘述。
进一步的，储水盒1内安装有水位传感器10，三通阀6与水位传感器10通信连接。具体的，三通阀6为电磁阀，水位传感器10和三通阀6分别与控制器通信连接，水位传感器10用于检测储水盒1内的水位高度，控制器可根据储水盒1内的水位高度调节三通阀6的阀芯位置。当水位高度达到设定值时，控制三通阀6连通入水口61和第一出水口62；当水位未到达设定值时，则控制三通阀6连通入水口61和第二出水口63。
本申请实施例中，室外机排水管3与储水盒1的连通管路内设有过滤网8，用于过滤室外结霜水或冷凝水的杂质，以提高加湿水的质量，减少或避免加湿器的定期维护，降低维护成本。当然，室外机排水管3与储水盒1的连通管路包括三通阀6，过滤网8也可以设置于三通阀6内，如图1所示。
本申请实施例中，室外机200安装有集水装置，用于收集室外机200的冷凝水或结霜水，其中，集水装置可以为位于安装于室外机200下方的集水盘，集水盘的出水口与室外机排水管相连。集水装置的安装高度高于储水盒1的安装高度，使得集水装置内的水能够在重力作用下自然流入储水盒1。当然，室内机100也安装有集水装置，用于收集室内机100的冷凝水或结霜水，该集水装置的安装高度也高于储水盒1的安装高度。
如图1所示，本申请实施例中，室内机100包括机壳101，机壳101设有进风口和出风口1011以及连通进风口和出风口1011的风道，储水盒1安装于机壳101内，加湿体4位于所述储水盒外的部分位于所述风道内，风机用于驱动空气从进风口流入所述风道并从出风口1011流出。空气从进风口进入风道并经加湿体4加湿后从出风口1011吹出。其中，加湿体4可设置于风道的任一位置，例如，靠近出风口1011的位置或者靠近进风口的位置。
进一步的，室内机100还包括蒸发器102，蒸发器102安装于所述风道内，也即该风道为空调换热系统的换热风道。加湿体4位于该换热风道内。所述风机为换热系统的贯流风机，也即加湿装置与空调换热系统共用一个风机。储水盒1可安装于换热风道内或换热风道外，只要保证位于储水盒1外的部分加湿体4位于换热风道内即可。该出风口1011为空调换热系统对应的室内风出风口。空调换热系统在运行过程中，经蒸发器102换热后的部分空气在贯流风机的作用下经过加湿体4后从出风口1011吹出，达到加湿效果。本实施例中的空调器无需在空调器上设置单独的加湿器出风口，简化了机壳101的结构。
本申请还提供一种空调器的加湿控制方法，图3是本申请提供的空调器的加湿控制方法的流程示意图，该空调器的加湿控制方法包括步骤：
S100，获取环境的当前相对湿度；
S200，根据所述当前相对湿度控制所述风机的转速和加热棒9的输出功率。
具体的，可通过湿度传感器检测环境的当前相对湿度并将检测结果发送给控制器。控制器根据当前相对湿度确定风机的转速和加热棒9的输出功率，并相应的控制风机和加热棒9的工作。加湿体4将储水盒1内的水吸至储水盒1外，在风机作用下，储水盒1上方产生的气流流经加湿体4，使加湿体4中的水分扩散到环境当中。随着风机转速的增大，单位时间流经加湿体4的空气流量则会增多，从而会加快加湿体4内水分的扩散。加热棒9位于储水盒1内，用于对储水盒1内的水进行加热，使储水盒1内的水直接以水蒸气的形式扩散到环境中。可通过调节加热棒9的输出功率来调节加热棒9的制热效率，从而调节储水盒1内的水的蒸发速率，以增大除湿力度。
本申请实施例中，在步骤S100中获取环境的当前相对湿度之前，还包括开启所述风机和UV光除菌器5，即在系统开启加湿功能时，同时开启UV光除菌功能，利用UV光除菌器5对加湿体4进行除菌，防止加湿体4滋生细菌，保证输出干净的湿空气。
本申请实施例中，步骤S200中，根据所述当前相对湿度控制所述风机的转速和加热棒9的输出功率，包括：
S201，获取环境的当前温度和目标相对湿度；
S202，根据所述当前温度和所述目标相对湿度，确定需对所述当前相对湿度进行的湿度补偿；
S203，根据所述湿度补偿调节所述风机的转速和加热棒9的输出功率。
具体的，可通过温度传感器检测环境的当前温度并将检测结果发送给控制器。当然，也可以采用温湿度传感器检测环境的当前温度和当前相对湿度。目标相对湿度可以为系统自带也可以通过用户根据自身需要人为设定。控制器比较当前相对湿度和目标相对湿度，根据当前相对湿度和目标相对湿度的差值，并在当前温度下对当前相对湿度进行温度补偿。根据该温度补偿确定合适的风机转速和加热棒9的输出功率，并相应的控制风机和加热棒9的工作。
本申请实施例中，可根据设定的相对湿度区间来调节风机转速和加热 棒9的输出功率，以简化调节步骤。具体的，步骤S200中，所述根据所述当前相对湿度控制所述风机的转速和所述加热棒的输出功率，具体包括：
S204，若所述当前相对湿度小于第一相对湿度阈值，则控制所述风机的转速为第一转速，加热棒9的输出功率为第一输出功率；
S205，若所述当前相对湿度不小于第一相对湿度阈值且小于第二相对湿度阈值，则控制风机的转速为第二转速，加热棒9的输出功率为第二输出功率；
S206，若所述当前相对湿度不小于第二相对湿度阈值，则控制风机的转速为第三转速，加热棒9的输出功率为第三输出功率；
其中，所述第三转速小于所述第一转速和所述第二转速，所述第一输出功率大于所述第二输出功率和所述第三输出功率。
具体的，第一相对湿度阈值和第二相对湿度阈值可以为系统自带，也可以通过用户根据自身需要设置人为设定。第一相对湿度阈值和第二相对湿度阈值将湿度划分为三个湿度范围区间。本实施例中风机的第一转速、第二转速和第三转速，以及加热棒9的第一输出功率、第二输出功率和第三输出功率均可以为根据温度补偿计算得到的，也可以为预先设定的定值。
例如，第一相对湿度阈值为20％，第二相对湿度阈值为40％。若前相对湿度小于20％，此时判断环境比较干燥，则控制调节风机的转速为最大转速，加热棒9的输出功率为最大输出功率，将加湿力度调节到最大；若前相对湿度不小于20％且小于40％，此时判断环境相对干燥，则控制调节风机保持以最大转速运转，或者以较大转速运转，加热棒9的输出功率为0，即关闭加热棒9；若前相对湿度不小于40％，此时判断环境湿度较为适宜，则控制调节风机的转速为以较低转速运行并关闭加热棒9。
进一步的，若所述当前相对湿度在预设的标准相对湿度范围内，则控制所述风机的转速为最低转速并控制加热棒9关闭。其中，标准相对湿度可由系统自带，也可以通过用户根据自身需求人为设定。系统实时根据当前相对湿度调节风机的转速和加热棒9的输出功率，直至当前相对湿度达到标准相对湿度范围。例如，标准相对湿度范围为相对湿度不小于50％。当检测到当前相对湿度达到50％时，控制风机以最低转速运行并关闭加热棒9，此时加湿装置进入休眠状态。
进一步的，本申请实施例中，三通阀6和水位传感器10通信连接。具体的，控制器分别与三通阀6和水位传感器10通信连接。当水位传感器10检测到储水盒1内的水位高于设定最高水位时，控制器控制三通阀6的电磁阀芯移动，关闭第一出水口62，打开第二出水口63，以将室内机排水管或室外机排水管内多余的水排出到外界，避免储水盒1的水溢出。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
