根据本申请实施例的空调室内机100，将驱动模块11设置于电控腔室102内，并设置通风口103对电控腔室102内部空间进行散热，有利于驱动模块11的稳定运行，并方便驱动模块11与空调室内机100的主控制器进行信号交换，提高对风机组件20的控制效率和效果。
另外，电控腔室102与送风风道101可以相互隔开，在电控腔室102与送风风道101隔开时，电控腔室102与送风风道101可以并非完全隔离，电控腔室102与送风风道101之间也可以设置通风口进行连通，从而可以利用风机组件驱动空气在电控腔室102内流通，实现散热。当然电控腔室102与送风风道101也可以完全隔离。
其中，空调室内机还包括换热器，换热器设于壳体10内，以适于与气流换热。
本申请中的风机组件20可以包括风机21和电机22，风机21设于送风风道101内以驱动气流，电机22与风机21传动连接，以通过电机22驱动风机21，实现对气流的驱动，驱动模块11与电机22电连接，驱动模块11可以驱动电机22运行。另外，壳体10内可以设置换热器，而风机21可以驱动气流流经换热器以进行散热。
其中，电控腔室102上可以设置至少两个通风口103，以使电控腔室102内在通风口103之间构造出散热通道。通过设置多个通风口103，可以方便电控腔室102内的气流流通，实现对电控腔室102内的快速散热。另外，电控腔室102也可以仅设置一个通风口103，而气流可以从电控腔室102上的缝隙处进入到电控腔室102内，或从缝隙处排出，从而与通风口103组合形成气流的循环通道。而且，可以在电控腔室102的壁上设置多处缝隙，以提高散热的面积和效果。还可以在电控腔室102上设置一个通风口103，通过该通风口103进行气流的进出。
另外，如图2，空调室内机100可以包括主控模块12，主控模块12用于控制空调室内机100的运行，其中主控模块12可以设于电控腔室102内，也可以设置空调室内机100的其他位置。如图2至图12，在本申请的一些实施例中，电控腔室102内还设有主控模块12，驱动模块11与主控模块12电连接。驱动模块11与主控模块12之间的连接，能够方便进行信号传输，提高了信号传输的效率和效果。保证驱动模块11和主控模块12能够稳定。

另外，本申请的驱动模块11与主控模块12可以设置为分体式结构，也可以设为一体式结构，也就是说，驱动模块11与主控板可以集成于同一电路板上，也可以分别具有不同 的电路板结构。
如图3和图4，在本申请的一些实施例中，驱动模块11与主控模块12集成于同一电路板上。通过驱动模块11和主控模块12均设置于电控腔室102内，可减少结构件的数量，且驱动模块11和主控模块12之间的距离更近，信号传输距离短、传输速度更快，可更加快速的调整空调室内机100的出风量，方便对风机组件20进行控制，提高对驱动模块11的散热效率，加强散热效果。除此之外，将两个模块设置于同一个电控腔室102内，空调室内机100在组装过程中组装效率更高，可在一定程度上降低生产成本，也便于后续的维护和检修。
在本申请的另一些实施例中，如图5至图12，主控模块12和驱动模块11为分体式结构。可以降低主控模块12与驱动模块11的相互干扰。而且可以对相关技术中主控模块12、驱动模块11的结构无改动或改动小，可以降低空调室内机100的成本。
其中，可以将驱动模块11安装到主控模块12上，也可以将驱动模块11与主控模块12分开布置。
例如，在一些实施例中，可以将驱动模块11安装于主控模块12上，可以实现驱动模块11与主控模块12的集成，在对驱动模块11和主控模块12的结构改变较小的同时，能够方便空调室内机100的控制模块集成，方便空调室内机100的生产、装配以及维护。
其中，驱动模块11与主控模块12可以具有不同的配合和位置关系，如图5至图7，可以将驱动模块11垂直设于主控模块12上，这样可以将驱动模块11的占用空间，具体而言，主控模块12上一般具有体积较大的电容等结构，通过将驱动模块11垂直设置，能够充分利用主控板上的空间，提高空间利用率，从而可以降低驱动模块11和主控模块12组合形成的控制模块所占用的空间。
另外，也可以将驱动模块11与主控模块12相互平行的设置。其中，在沿垂直于主控模块12的投影中，驱动模块11的投影可以完全落入到主控模块12上、部分落入主控模块12上、或完全落入主控模块12外。例如，可以将驱动模块11连接于主控模块12的边沿，从而尽量降低主控模块12与驱动模块11之间的相互干扰；也可以将驱动模块11与主控模块12在主控模块12的法向(参照图1中的左右方向)上相对设置，以提高空间利用率，同时也能降低信号干扰，并方便散热。
另外，还可以将驱动模块11相对于主控模块12倾斜预定角度，其中，在沿垂直于主控模块12的投影中，驱动模块11的投影可以完全落入到主控模块12上、部分落入主控模块12上、或完全落入主控模块12外。例如，可以将驱动模块11连接于主控模块12的边沿，并朝向远离主控模块12的方向、或与主控模块12法向相对的方向倾斜延伸。通过驱动模块11的倾斜设置，能够方便驱动模块11与主控模块12的连接，且倾斜设置能够降低 驱动模块11和主控模块12支架的间距，从而方便对控制模块进行装配和维护，同时也能降低信号干扰，并方便散热。
可选地，如图4和图5，在本申请的一些实施例中，驱动模块11安装于主控模块12的角部位置，结合前述，在驱动模块11与主控模块12集成于同一电路板上时，可以在主控模块12的电路板上靠近边沿的位置集成驱动模块11的电子元器件。同样的，在驱动模块11与主控模块12为分体结构时，可以在主控模块12的电路板上靠近边沿的位置安装驱动模块11。当然，还可以采用其他的方式将驱动模块11安装于主控模块12的角部位置。可以利于驱动模块11的散热，且可以避免驱动模块11与主控模块12上的其他部件发生干涉。通过将驱动模块11与主控模块12相连，进行合理布局，既可以实现节省空间的还可以达到较好的散热效果；且驱动模块11与主控模块12采用特定结构安装固定使得整体结构稳定可靠。
其中，主控模块12的角部位置可以是主控模块12上靠近主控模块12边沿的位置。当主控模块12上具有呈夹角的多个边沿时，可以将相近的两个以上的边沿围绕出的区域设为主控模块12的角部，例如，主控模块12可以设置为长方形形状，此时，主控模块12的四个角即为主控模块12的角部位置。同样地，当主控模块12为三角形、五边形等等形状是，主控模块12的各角即为主控模块12的角部位置。另外，主控模块12也可以设置为圆形、椭圆形或其他形状，也同样可以将主控模块12上邻近边沿的区域认定为主控模块12的角部位置。
另外，结合前述，驱动模块11与主控模块12为分体式机构，如图9至图12，还可以将驱动模块11与主控模块12在电控腔室102内分开布置，也就是说，将驱动模块11和主控模块12设于电控腔室102内的不同位置。可以提高运行的稳定性和安全性。可以避免二者之间发生信号干扰或互相影响，可以实现空调室内机100的集成化，且便于控制，提高了空调室内机100的模块化效果，便于主控模块12与驱动模块11之间的信号传输，以便于对风机组件进行控制，满足风机组件更为复杂的驱动要求。
其中，驱动模块11与主控模块12设于同一腔室内的不同位置，在散热过程中，可以同时对电控模块和驱动模块11进行散热。同样地，也可以将驱动模块11和主控模块12设于不同的腔室。例如，可以在电控腔室102内设置相互隔开的多个腔室，以用于分别存放主控模块12和驱动模块11。
例如，如图9和图10所示，可以将驱动模块11和主控模块12均平放于电控腔室102的壁上；如图11，也可以将主控模块12平放于电控腔室102的底壁上，而将驱动模块11平放于电控腔室102的侧壁上，等等，根据实际使用的需求，可以旋转驱动模块11与主控模块12的安装位置和安装形式。
如图12，在本申请的一些实施例中，电控腔室102内具有相互隔开的第一容置腔104和第二容置腔105，主控模块12设于第一容置腔104内，驱动模块11设于第二容置腔105内，驱动模块11与主控模块12电连接，且驱动模块11与风机组件电连接。驱动模块11与主控模块12分别设于电控腔室102内的第一容置腔104和第二容置腔105内，可以将驱动模块11与主控模块12分开布置，可以提高运行的稳定性。主控模块12和驱动模块11设置成分体结构，可以避免二者之间发生信号干扰或互相影响。更进一步地，驱动模块11与风机组件电连接，适于驱动模块11驱动风机组件运行，且驱动模块11与主控模块12电连接，便于主控模块12控制驱动模块11，从而更好的控制风机组件运行情况。在装配过程中，可以将主控模块12和驱动模块11装置分别装入第一容置腔104和第二容置腔105，提高了空调室内机100的模块化效果，便于主控模块12与驱动模块11之间的信号传输，以便于对风机组件进行控制，满足风机组件更为复杂的驱动要求。
其中，通风口103接通电控腔室102的外部空间和第二容置腔105。通风口103接通电控腔室102的外部空间和第二容置腔105，以适于第二容置腔105内的空气与电控腔室102外部进行换热，利于降低第二容置腔105内的温度。
可选地，电控腔室102呈扁平状的腔室，第一容置腔104和第二容置腔105沿预定方向布置，主控模块12平放于第一容置腔104内，且驱动模块11平放于第二容置腔105内或竖立于第二容置腔105内，其中，预定方向垂直于电控腔室102的厚度方向。电控腔室102呈扁平状的腔室，利于空间布置，主控模块12平放于电控腔室102内，且驱动模块11可以根据情况平放于电控腔室102内(驱动模块11的法线平行于电控腔室102的厚度方向)或竖立于电控腔室102(驱动模块11的法线垂直于电控腔室102的厚度方向)内。具体地，电控盒可以位于壳体10的一侧，便于空间布置，且便于维修和维护。电控腔室102的厚度方向参照附图1中的左右方向。
其中，扁平状的腔室是指，腔室的高度尺寸小于其长度尺寸和宽度尺寸。此时，腔室的高度所占用的尺寸较小，通过将主控模块12平方，可以充分地利用电控腔室102内的空间，而驱动模块11的尺寸较小，可以根据散热的需求对驱动模块11的位置进行设置，以提高散热的效果。
另外，电控腔室102与送风风道101沿风机组件20的轴向(参照附图1中的左右方向)排布，第一容置腔104和第二容置腔105沿风机组件20的轴向排布，也可以将第一容置腔104和第二容置腔105沿垂直于风机组件20的轴向的方向排布。通过第一容置腔104和第二容置腔105的排布，能够方便安装驱动模块11和主控模块12，以便于提高电控腔室102的空间利用率，并避免驱动模块11、主控模块12之间的热量、信号干扰，提高电控腔室102的稳定性。
结合图1和图12，风机组件20的轴向参考附图中的左右方向，其中，第一容置腔104和第二容置腔105可以沿前后方向排布。另外，也可以在电控腔室102内设置沿风机组件20轴线方向上的多层腔，以构造出第一容置腔104和第二容置腔105；另外，还可以将第一容置腔104和第二容置腔105呈内外排布，例如，将第一容置腔104绕设于第二容置腔105外侧；或将第二容置腔105绕设于第一容置腔104外侧等。当然，本申请中第一容置腔104和第二容置腔105的排布形式，仅仅是本申请的一些具体实施方式，并非是对本申请保护范围的限制。
如图12，在本申请的而一些实施例中，第一容置腔104和第二容置腔105沿垂直于轴向的方向排布。其中，第一容置腔104和第二容置腔105可以设置成沿图示中的前后方向、上下方向等进行排布。从而可以减小电控腔室102在风机组件20的轴向上的厚度尺寸，从而缩小整机尺寸，或提高空调室内机的送风风道和换热模块的体积等，提高空调室内机的功率和能效。
另外，主控模块12垂直于轴向，且驱动模块11垂直于轴向或平行于轴向。从而可以充分的利用电控腔室102内的空间，提高空间利用率和换热效率效果。
结合图12，电控腔室102内设有隔板106，隔板106与电控腔室102的壁的一部分合围出第二容置腔105，且通风口103设于电控腔室102的壁上与隔板106配合的部分上。具体地，隔板106可以在电控腔室102内构造出容置空间，驱动模块11安装于容置空间内，可以将驱动模块11与电控腔室102内的其他元器件分隔开，这样，可以减缓驱动模块11的热量向其他元器件传递，可以避免互相干扰。此外，在一些特殊情况下，当驱动模块11或其他元器件发生故障时隔板106也可以起到隔绝作用，从而降低风险，提高安全性，且驱动模块11单独设置还可以便于维护和维修。进一步地，通风口103设于与隔板106配合的部分上，也就是说，通风口103可以连通第二容置腔105和外部空间，便于第二容置腔105内的热量通过通风口103散出，提高了第二容置腔105的通风效果，利于驱动模块11散热，可以实现第二容置腔105的独立散热。
另外，通过将电控腔室102的壁的一部分构造出第二容置腔105的壁，能够方便设置通风口103以实现气流流通。
在本申请的一些实施例中，第一容置腔104被构造成密封的空腔。由此，第一容置腔104内的主控模块12可以与第二容置腔105内的驱动模块11在电控腔室102内分离布置，可以对主控模块12提供有效地保护，避免外部的尘土、水等进入到第一容置腔104内，也能够避免外部的含尘气流、含水气流等进入到第一容置腔104内，提高主控模块12运行的稳定性，并可以在一定程度上避免产生凝露。当然第一容置腔104的壁可以设为导热材料，以便于与外部环境进行换热，实现主控模块12的散热和冷却。
结合图12，隔板106在电控腔室102内合围出“U”形结构，且U形结构的开口端连接于电控腔室102的壁上，且该壁上设有通风口103，由此，构造出第二容置腔105。驱动模块11平放于第二容置腔105内，且散热板与驱动模块11相对，散热板覆盖于驱动模块11的上方。其中，第二容置腔105的尺寸可以设置成适于放置驱动模块11的形式，以提高空间利用率。
本申请中，可以通过空调室内机100的壳体10的壁构造出电控腔室102，也可以在壳体10内设置电控盒，以通过电控盒构造出电控腔室102。其中，电控盒可以包括金属外壳以及设置于金属外壳内的塑料内壳。具体地，电控腔室102的内壳可以采用塑料，具有一定的绝缘性和阻燃性，可以降低由于内部电路故障可能引起的漏电风险；外壳可以采用金属材料，金属材料具有一定的防火性且抗变形能力较强，可避免温度过高导致电控腔室102内部起火时对电控腔室102外部器件的影响。在本申请的另一些实施例中，电控腔室102还可以为耐火材料，可以直接采用耐火材料注塑或者其他方式一体加工电控腔室102即可，制作工序更简单，更加便于生产。
另外，本申请中的通风口103可以设于电控腔室102的不同位置，根据实际需求，可以选择不同的通风口103位置。其中，可以设在电控腔室102的朝向壳体10回风侧的一侧(参照图1中电控腔室101的前侧)、朝向壳体10送风侧的一侧(参照图1中电控腔室101的后侧)、朝向送风风道101的一侧(参照图1中电控腔室101的左侧)、背离送风风道101的一侧(参照图1中电控腔室101的右侧)、顶壁(参照图1中电控腔室101的上侧壁)和底壁(参照图1中电控腔室101的下侧壁)中的至少一处设有通风口103。其中，送风风道101具有送风口和回风口，壳体10具有回风侧和送风侧，在风机组件20的驱动作用下，回风侧的气流将通过回风口进入到送风风道101内，并在送风风道101内进行换热后，通过送风口送出至送风侧，随后进入到室内后回流至壳体10的回风侧，从而形成换热循环。
举例而言，电控腔室102的朝向送风风道101的一侧设置通风口103时，可以利用风机组件20驱动气流通过电控腔室102，来实现对电控腔室102的散热。另外，可以在壳体10内设置风道来将一个或多个通风口103与风机组件20相连通，也可以如图9所示，设置散热风扇16等结构来单独驱动电控腔室102内的气流流通，还可以依靠电控腔室102内外气流的自然流通实现冷却和散热。
需要说明的是，壳体10内的空气通过送风口送往壳体10送风侧，壳体10外的气流可以通过回风口送入到壳体10回风侧。如图1所示，壳体10内具有沿前后方向延伸的送风风道101，送风风道101的前端构造出回风口，送风风道101的后端构造出送风口，因此，壳体10的前侧为壳体10的回风侧，壳体10的后侧为壳体10的送风侧。另外，电控腔室 102设于送风风道101的右侧，因此，电控腔室102的左侧为电控腔室102朝向送风风道101的一侧，电控腔室102的右侧为电控腔室102背离送风风道101的一侧。其中，在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
另外，驱动模块11可以包括智能功率模块和微控制单元集成电路等电子元器件，以适于驱动风机组件20工作，具体地，风机组件20可以包括一个或多个风机，其中，可以通过驱动组件驱动一个、两个或者多个风机转动，当空调室内机100包括多个风机时，多个风机沿空调室内机100的长度方向(参照附图1中的左右方向)分布。
如图2，在本申请的而一些实施例中，电控腔室102的侧壁上设有通风口103，且通风口103在从电控腔室102内侧到外侧的方向上，至少一部分向下延伸。将通风口103的至少一部分向下延伸，这样，在气流通往电控腔室102内时，即使存在灰尘等杂质或产生冷凝水，也会通过通风口103中向下延伸的部分阻挡，避免直接流入到电控腔室102内，从而提高对电控腔室102的防护。另外，也保证了气流的流通，可以提高换热的效果。
在本申请的一些实施例中，通风口103处设有防尘网和/或干燥层。通过防尘网和干燥层，能够实现通往电控腔室102内的气流维持在干燥无尘，避免水气等跟随空气进入到电控腔室102内在电控腔室102内产生的冷凝水，使得电控模块能够稳定地运行。
在将驱动模块11设置于电控腔室102内之后，驱动模块11将成为电控腔室102内最主要的热源之一，因此，需要提高对驱动模块11的散热效果。本申请中可以将驱动模块11设置于前述的散热通道流经的位置。进一步地，可以将驱动模块11与一通风口103相对设置，以进一步地提高散热的效果。其中，如前所述电控腔室102可以具有两个以上的通风口103，也可以将多个通风口103与驱动模块11相对，以进一步地提高对驱动模块11的散热效果。
为了进一步地提高电控腔室102的散热效果，维持驱动模块11等运行的稳定性，在本申请的一些实施例中，空调室内机100还包括散热器15，散热器15设于电控腔室102内部或至少部分位于电控腔室102外部。其中，在散热器15至少部分设置电控腔室102内时，可以将散热器15与通风口103相对，通过气流来带走散热器15上的热量，以提高电控腔室102内的散热效率和效果。如图13，散热器15可以设于电控腔室102内，也可以将散热器15的至少一部分伸出电控腔室102，可以散热器15将热量引出电控腔室102，来实现对电控腔室102内的散热，其中，通过增加散热器15，可以提高与空气的接触面积，以提高对电控腔室102内元器件的散热效果。
结合图5和图6，在本申请的一些实施例中，驱动模块11水平设置，驱动模块11的驱动芯片设于驱动模块11的上侧，散热器15设于驱动芯片的上方，并遮盖驱动芯片。具体地，由于空调室内机100通常呈竖直放置的形式，驱动模块11水平设置，可以充分利用空调室内机100水平方向的空间，利于减小空调室内机100体积。进一步地，驱动芯片设于驱动模块11上侧，既可以面向散热器15，又可以使散热器15可以位于驱动芯片的上方，这样，可以提高散热器15对驱动芯片的散热效果，同时散热器15还可以遮挡驱动芯片，避免驱动芯片累积灰尘，提高防尘功能，避免影响芯片运行；且利于空间布置。
另外，驱动模块11中的其他电子元件，可以设置驱动模块11的下侧，这样可以进一步地维持驱动模块11的运行环境。
结合图5，在本申请的一些实施例中，散热器15完全覆盖驱动模块11上的驱动芯片，利于散热器15对驱动芯片进行快速降温，且散热器15的周缘伸出驱动芯片，并与驱动模块11之间具有气隙。这样，在散热器15周缘与驱动板之间的间隙可以形成风道，利于气流流过，提高散热效果，还可以提高散热器15的换热面积。
结合图1至图13，本申请中的散热器15可以安装于主控模块12上，也可以安装于电控腔室102的壁上，本申请中，可以在散热器15与对接结构(例如前述的电控腔室102的壁、主控模块12等)之间设置绝缘结构，以维持电控腔室102内元器件的运行稳定性。其中，空调室内机100还包括绝缘支撑17，可以通过绝缘支撑17将散热器15安装于对接结构上，提高结构稳定性，此外，可以在两者之间形成间隙，风从间隙吹过时，可以带走热量从而利于提高散热效果。
在本申请的一些实施例中，散热器15与驱动模块11换热连接，可以实现对驱动模块11进行散热，提高散热效果，利于实现驱动模块11的稳定运行，避免驱动模块11过热，提高其使用寿命。
结合图8，在本申请的一些实施例中，驱动模块11具有模块引脚，驱动模块11通过模块引脚与主控模块12连接，可以实现驱动模块11与主控模块12的分开连接，同时利于实现主控模块12对驱动模块11的控制，利于实现集成化，利于降低驱动模块11与主控模块12支架之间的干扰和影响。
其中，引脚可以是一个或者多个，例如为1个引脚，利于简化结构。模块引脚处可以设置光箔。散热光箔可以进一步增强散热效果，可以避免驱动模块11与主控模块12的连接处过热，从而降低强电与弱电之间的干涉。模块引脚为台阶状结构，利于提升整体结构可靠性。具体地，模块引脚的一端插装于主控模块12的主控模块12上，且模块引脚的台阶面支撑于主控模块12上，可以提高引脚与主控模块12的连接时的接触面积，提高连接的结构稳定性。
可选地，散热器15的翅片间隙与一通风口103相对。具体而言，散热器15包括多个翅片，多个翅片沿第一方向(参照图8中垂直于纸面的方向)延伸并沿第二方向(参照图8中的上下方向)间隔开，且多个翅片与至少一个通风口103沿所述第一方向相对，从而可以优化散热效果。
可选地，电控腔室102内可以设有用于检测温度的温度传感器，当电控腔室102内温度较高时，温度传感器可以发出提示，以提高空调室内机100运行安全性。也可以是，将温度传感器与驱动模块11和散热器15中的至少一个相连或温度传感器靠近驱动模块11，以检测驱动模块11的温度，从而合理控制散热器15的，以提高散热效果且利于节能。
其中，空调室内机100还可以包括电控盒，电控盒设于壳体10内，电控盒内构造出电控腔室102。具体地，电控盒具有防尘功能，可以保护电控腔室102内部器件的安全性。具体地，电控盒可以位于壳体10的一侧，便于空间布置，且便于维修和维护。电控盒可以设有本体和盖体，本体和盖体为可拆卸式连接，盖体可以封盖本体，以保护腔室内元器件。当需要对电控腔室102及其内部的主控模块12或驱动模块11进行维修或更换时，打开盖体即可。
本申请中，将驱动模块11设置在电控腔室102内，驱动模块11与电机22分离设置，便于对驱动模块11进行灵活设计。例如，可以灵活设计驱动模块11上的电路、接口，以优化驱动模块11的功能；在使用过程中，用户也能够更方便地对驱动模块11进行维修、改造。
将驱动模块11设于电控腔室102内，可以方便装配和维护，在对驱动模块11检修过程中，不需要拆卸风机组件20，提高维护的效率，并避免了维修过程中造成的损坏，还可以方便对驱动模块11进行升级，以便于满足人们对空调室内机100的日益增加的功能要求。将驱动模块11设置于电控腔室102内，也能够避免驱动模块11设于电机22内导致电机22体积过大影响送风风道101空间的问题，也可以避免将驱动模块11放在送风风道101内占用送风风道101内的空间，从而提高送风风道101的送风量。
而且，将驱动模块11设于电控腔室102内，充分利用电控腔室102内的剩余空间。例如，电控腔室内102的主控模块存在体积较大的元器件(例如电容等)、也存在体积较小的元器件(例如电阻等)，这些元器件装在一起时，电控腔室102内存在较多剩余空间。
可见，本申请中将驱动模块11设于电控腔室102内，不会对空调室内机的其他结构造成影响，也不会增大对电控腔室102的空间需求，可以适用于现有的空调室内机中，降低模具成本。另外，可以方便实现驱动模块的升级和扩展等，在需要变更或增加驱动模块或电机的功能时，只需要更换驱动模块11即可。在空调室内机100的生产、装配、维护过程中，可以在不改变空调室内机100的整机结构的情况下，就可以完成驱动模块11的更新和 变更，而不会造成装配工艺、模具结构的变化，降低成本，优化了空调室内机的模块化设计。例如，对于具有恒风量出风功能和不具有恒风量出风功能的空调室内机，空调室内机的生产工艺不变，变更驱动模块即可。
