如图1至图3所示，在本实施例提供的一种空调器室内机中，该空调器室内机包括室内机本体1以及设置于室内机本体1上的噪音收集器2和反噪音发生器3。室内机本体1包括设置在其外侧的出风口11以及设置于其内部的电脑板12；电脑板12的信号输入端与噪音收集器2通信连接， 电脑板12的信号输出端与反噪音发生器3通信连接；噪音收集器2的外表面设置有收音孔21；反噪音发生器3的外表面设置有发声口31，且反噪音发生器3设置成其发声口31位于出风口11的同侧。
示例性地，虽然附图1和2是以柜式空调器室内机为例、图3是以壁挂式空调器室内机为例对本实施例的室内机本体以及1空调器室内机进行说明的，但本实施例中的空调器室内机的类型并不限于此。在不偏离本发明原理的条件下，本领域技术人员可以根据需要对本实施例的空调器室内机的类型作出调整，以便适应具体的应用场合。可以理解的是，只要是使用了本实施例的上述技术手段来实现空调器室内机的降噪功能，即属于本实施例说明的空调器室内机以及本发明要求保护的空调器室内机的范围。
可以理解的是，本实施例的空调器室内机是在现有的空调器室内机的基础上进行的改造，故本实施例中的室内机本体1泛指现有的未使用上述技术手段来实现空调器室内机的降噪功能的所有现有空调器室内机。其中，室内机本体1除了上述提及的柜式、壁挂式之外，该室内机本体1还可以为吊顶式、嵌入式等。
其中，该噪音收集器2包括至少一个麦克风，即该噪音收集器2可以为通过一个麦克风收集室内的噪音；并且该噪音收集器2还可以设置有多个噪音收集器2，以分别用于检测不同方位的噪音，从而使得噪音收集效果更好。此外，反噪音发生器3包括至少一个扬声器，即该反噪音发生器3可以仅设置有一个扬声器，也可以设置有朝向多个方位的扬声器，以分别针对不同方位的噪音起到有效的消除作用。
如图4所示，该空调器室内机中的电脑板12包括存储器121和处理器122；存储器121与处理器122电连接；存储器121中存储有预先采集的多个噪音数据以及与其呈映射关系的反噪音数据；处理器122上设置有信号输入端和信号输出端。由于空调产生的噪音有其固有的一个或多个频率或者频率范围，在上述映射关系中，噪音的声波与反噪声的声波均可以由正弦波表示，每个噪音数据与其对应的反噪音数据的频率相同而相位相差半个周期，如此，噪音的声波与反噪音的声波频率相同，当噪音声波的波峰与反噪音的声波的波谷叠加后会形成振幅很小的声波，以起到降噪的作用。
其中，该存储器121包括但不限于随机存储器、闪存、只读存储器、可编程只读存储器易失性存储器、非易失性存储器、串行存储器并行存储器或寄存器等，该处理器122包括但不限于CPLD/FPGA、DSP、ARM处理器、MIPS处理器等。
在本实施例提供的一种空调器室内机中，室内机本体1上设置有噪音收集器2和反噪音发生器3，且室内机本体1中电脑板12的信号输入端与噪音收集器2通信连接，电脑板12的信号输出端与反噪音发生器3通信连接。如此，该空调器室内机能够根据噪音收集器2接收到的噪音数据产生反噪音数据并由反噪音发生器3发出与该噪音频率相同而相位相差半个周期的声波，以减弱或者抵消室内机本体1产生的噪音。同时，由于室内机本体1产生的噪音大多通过出风口11向室内传播，而反噪音发生器3设置成其发声口31位于室内机本体1的出风口11的同侧，从而更可靠地保证了该空调器室内机的降噪效果。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，如图1至图3所示，室内机本体1的内部设置有摆风组件，摆风组件包括摆叶45(如图2中叶扇4由多个摆叶45构成，或者如图3中铰接在共同的第一摆杆51上的多个摆叶45)和电机41；电机41通过第一传动部件(如图2中包括第一转轴43和第一副齿轮44，或者图3中包括第一摆杆51和未示出的第一连接柱)驱动摆叶45摆动，电机41还通过第二传动部件(如图2中的第二转轴32和第二副齿轮33，或者如图3中未示出的第二摆杆和第二连接柱)驱动反噪音发生器3与摆叶45同步摆动。
如此，在本实施例提供的一种空调器室内机中，电机41通过第一传动部件驱动摆叶45摆动的同时，还通过第二传动部件驱动反噪音发生器3与摆叶45同步摆动。如此，能够使得反噪音发生器3的发声口31随着摆叶45的摆动方向的改变而同步改变，并使发声口31始终朝向室内机本体1的出风方向。同时，反噪音发生器3与摆叶45由同一电机41驱动，一方面提高了电机41的利用率并节约了成本，另一方面能够准确地保证摆叶45和反噪音发生器3的摆动方向始终一致，并进一步提高了该空调器室内机的降噪效果。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，如图1和图2所示的室内机本体1为立柜式；在该立柜式空调器室内 机中，第一传动部件包括第一转轴43以及同轴连接在第一转轴43上的第一副齿轮44；摆叶45连接在第一转轴43上并平行于第一转轴43；第二传动部件包括第二转轴32以及同轴连接在第二转轴32上的第二副齿轮33；反噪音发生器3连接在第二转轴32上；第一转轴43与第二转轴32平行且均转动设置在室内机本体1上；电机41的输出轴上同轴套接有主齿轮42，主齿轮42的一侧与第一副齿轮44啮合且另一侧与第二副齿轮33啮合。
示例性地，在该立柜式空调器室内机运行过程中，电机41的输出轴转动过程中，同时带动第一副齿轮44和第二副齿轮33绕相同的方向转动(即均顺时针转动或均逆时针转动)，使得摆叶45和反噪音发生器3同步摆动且摆动的方向相同，如此，保证了反噪音发生器3发出的声波与噪声的声波基本都沿着空调器室内机出风方向，从而极大地保证了空调器室内机的降噪效果。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，如图1中的A-A剖面图中，多个摆叶45绕第一转轴43的环向间隔设置并形成叶扇4。该叶扇4中绕转轴43最外两侧的摆叶45之间形成的夹角与摆叶45摆动的角度和出风口11的宽度相适应，即能够保证叶扇4往复摆动过程中，正对出风口11的摆叶45数量基本相等，以保证空调器室内机的摆风效果。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，需要说明的是，本实施例的第一转轴43上可以只是设置一个叶扇4。而在图1所示的柜式空调器室内机中，出风口11的长度沿着竖直方向，故图3所示第一转轴43沿其轴向间隔设置有多个叶扇4，能够满足空调器室内机沿其出风口11的长度方向的摆风效果。可以理解的是，该叶扇4中每个摆叶45沿径向的长度以及沿轴向的长度均可以根据该柜式空调器室内机本体1的尺寸以及摆风的强度要求来进行适应性的设置或者调整。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，在图1和图2中的柜式空调器室内机中，噪音收集器2设置在室内机本体1的上端，并可以相对于室内机本体1固定设置，而反噪音发生器3设置在噪音收集器2与室内机本体1之间。同时，该噪音收集器2在其外表面沿室内机本体1的轴向和周向均设置有多个收音孔21，以提高对室内各个方位噪音的收集效果。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，在图1和图2中的柜式空调器室内机中，该室内机本体1呈圆柱状，相应地，该噪音收集器2和反噪音发生器3均为与室内机本体1相匹配的圆盘状。如此，保证了空调器室内机整体在外部形状规格上的一致性，以及充分发挥该空调器室内机中噪音收集器2的噪音收集功能和反噪音发生器3产生噪音的功能，最终达到保证空调器室内机实现更好的降噪效果的目的。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，如图3所示的室内机本体1为壁挂式；其中，噪音收集器2和反噪音发生器3分别连接在室内机本体1的同侧(如图3中室内机本体1的右端，反噪音发生器3的发声口31位于出风口11的同侧)；第一传动部件包括第一摆杆51以及垂直并铰接在第一摆杆51的一端的第一连接柱(图中未示出)；多个摆叶45均铰接在第一摆杆51上，且多个摆叶45的两端还分别通过同轴连接的第一转杆52转动在室内机本体1的外壳内(如图3中该第一转杆52可以设置成垂直于纸面由外到内的水平方向)；第二传动部件包括第二摆杆(图中未示出)以及垂直并铰接在第二摆杆的一端的第二连接柱(图中未示出)；反噪音发生器3铰接在第二摆杆上，且反噪音发生器3还通过第二转杆(图中未示出)转动连接在室内机本体1的外壳内(如图3中该第二转杆可以竖直设置)；电机41的输出轴上同轴套接有转盘(图中未示出)，第一连接柱和第二连接柱分别连接在转盘的两侧外端并均平行于转盘的轴线，如此连接可以使得第一摆杆51与第二摆杆的摆动互不干扰。
可以理解的是，在如图3所示的壁挂式空调器中，电机41的输出轴带动转盘转动时，第一摆杆51与摆叶45的铰接部以及第二摆杆与反噪音发生器3的铰接部与电机41的输出轴之间的距离会周期性地发生改变，当摆叶45绕第一转杆52摆动的同时噪音发生器绕第二转杆摆动，使得噪音发生器与摆叶45同步摆动，以保证噪音发生器的发声口31始终朝向室内机本体1的出风方向，并保证了该空调器室内机的降噪效果。
当然，上述可以替换的实施方式之间、以及可以替换的实施方式和优选的实施方式之间还可以交叉配合使用，从而组合出新的实施方式以适用于更加具体的应用场景。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的保护范围之内并且形成不同的实施例。例如，在本发明的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
