具体实施方式
以下将结合说明书附图对本发明的具体实施方案进行详细阐述，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
首先，对具体实施方式中涉及到的技术术语作一简要说明：
下述在提到每个结构件的前或后、上或下、左或右时，是以结构件正常使用状态下相对于使用者的位置来定义的。而且，需要说明的是，用前或后、上或下、左或右仅是为了便于描述和简化描述，而不是指示或暗示所指的装置或结构件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对发明的限制。下述的热交换风是指来自空调本体内部、经热交换器热交换后的风；非热交换风是指来自空调本体所处环境空间的风，是相对于热交换风而言、不是直接来自于热交换器的风；混合风是指热交换风与非热交换风混合形成的风。
双贯流空调器包括室内机和室外机，室内机和室外机通过联机管连接实现冷媒的循环，室内机和室外机通过联机线连接实现供电和通讯，室内机接水盘的排水管引出至室外。
空调室内机包括至少两个空调本体，本实施例以立式空调室内机为例进行说明，参照图1-图4，本实施例的立式空调室内机包括两个空调本体，即第一空调本体100和第二空调本体200，第一空调本体100与第二空调本体 200对称设置。
第一空调本体100包括柱形第一壳体101，在第一壳体101上开设有第一进风口102和第一出风口103，第一壳体101内设置有第一风道105和第一贯流风扇104，第一贯流风扇104与第一进风口102之间设置有第一换热器106。第一贯流风扇104用于使空气从第一进风口102流向第一出风口103，也即，第一空调本体100工作时，第一贯流风扇104转动，将第一空调本体100外部的空气经过第一进风口102进入第一空调本体100内部，与第一换热器106进行热交换后，从第一出风口103吹出热交换风。在第一出风口103处设置有调整出风方向的第一摆叶(图中未示出)和/或第一导风板107，以满足用户的出风方向需求。第一出风口103、第一进风口102均为长条状。
第二空调本体200与第一空调本体100的结构相同。第二空调本体200包括柱形第二壳体201，在第二壳体201上开设有第二进风口202和第二出风口203，第二壳体201内设置有第二风道205和第二贯流风扇204，第二贯流风扇204与第二进风口202之间设置有第二换热器206。第二贯流风扇204用于使空气从第二进风口202流向第二出风口203，也即，第二空调本体200工作时，第二贯流风扇204转动，将第二空调本体200外部的空气经过第二进风口202进入第二空调本体200内部，与第二换热器206进行热交换后，从第二出风口203吹出热交换风。在第二出风口203处设置有调整出风方向的第二摆叶(图中未示出)和/或第二导风板207，以满足用户的出风方向需求。第二出风口203、第二进风口202均为长条状。
第一空调本体100和第二空调本体200之间形成贯通风道，贯通风道包括后侧的引风风道310和前侧的送风风道320，引风风道310用于将外部空气引入贯通风道。也即是，引风风道310和送风风道320分别位于贯通风道的后部和前部。外部空气自空调器后侧进入贯通风道，依次经由引风风道310和送风风道320，向空调器前侧吹出。第一空调本体100和第二空调本体200的后端形成引风风道310的后端引风口301，第一空调本体100和第二空调本体200的前端之间形成送风风道320的送风口302。第一空调本体100的第一出风口103和第二空调本体200的第二出风口203位于送风风道320内。第一贯流风扇104和第二贯流风扇204转动时，第一空调本体100和第二空调本体200内的热交换风分别从其出风口吹出至贯通风道内。第一出风口103和第二出风口203均位于贯通风道内且靠近送风口302的位置，第一出 风口103和第二出风口203吹出的风不会互相干扰，送风角度和送风距离大大提高，有利于室内空气的流动。在第一空调本体100和第二空调本体200的同一横截面上，第一空调本体100的前端、后端所在的第一连线与第二空调本体200的前端、后端所在的第二连线平行。第一空调本体100和第二空调本体200配置为对应的贯流风扇转动时产生的负压使第一空调本体100和第二空调本体200外部的空气经过后端引风口301进入贯通风道，也即非热交换风进入贯通风道内，热交换风和非热交换风在贯通风道内混合，形成温度适宜的混合风；送风口302送出贯通风道内的空气，也即混合风。第一出风口103和第二出风口203位于贯通风道内，出风口的出风能够在贯通风道内形成较大的负压，引入外部较多的非热交换风与热交换风混合形成混合风，混合风能够从送风口快速、均匀地扩散，送风温度较为均匀、舒适；贯通风道可以对吸入的非热交换风进行梳理，不仅有助于提高吸风量，且能够提高非热交换风与热交换风的混合均匀性，提高送风的舒适性及均匀性。
本实施例中贯通风道由第一壳体101和第二壳体201之间的间隙形成，贯通风道的风道壁为第一壳体101和第二壳体201的相对侧，也即第一壳体101和第二壳体201的内侧面。该内侧面是指位于空调器内部的、且位于贯通风道内部的侧面。当然，贯通风道的风道壁也可以是单独设置的，独立于第一壳体101和第二壳体201，能够与壳体固定或不与壳体固定的风道壁，此时，贯通风道为风道壁之间的空间。当然，风道壁也可以包括部分壳体和单独设置的部分风道壁，部分风道壁与部分壳体固定形成为一体，共同形成完整的风道壁，此时，贯通风道为部分风道壁之间、部分壳体之间的空间。
本实施例中，第一壳体101和第二壳体201的横截面均为近似椭圆形，当然，本发明中的第一壳体101和第二壳体201的横截面也可以为椭圆形、圆形、三边形和多边形等，均在本发明的保护范围之内。
进一步地，贯通风道内还设置有导板410。导板410通过由第一驱动机构驱动510驱动，能够绕贯通风道在长度方向上的中线旋转，通过调节打开角度调节进入引风风道310的引风量。贯通风道的长度方向L为图1中双向箭头所示的方向，中线C垂直于纸面延伸。其中，如图5和和图6所示，导板具有中空腔体411，可以减小导板的重量，便于导板的调节。导板410的截面形状优选为长方形、椭圆形或针锥形的一种。导板的中空腔体411截面优选为针锥形，以保证导板410的强度。
进一步地，导板410还由第二驱动机构520驱动，能够在引风风道310和送风风道320之间前后运动。第一驱动机构510驱动导板410转动，当导板410位于引风风道310时，能够通过调节打开角度调节进入引风风道310的引风量；当导板位于送风风道320时，能够通过调节打开角度，与第一出风口的第一导板107和第二出风口的第二导板207相互配合，调节送风风道320的出风风向。
在本实施例中，导板410设置在贯通风道在长度方向上的中线上，且能够绕该中线旋转，导板410的旋转中心设置在导板中间。当导板410运动到引风风道310时，导板410可转动至完全打开状态，此时，导板410与第一空调本体100和第二空调本体200的对称面重合，导板410对后侧的引风风道的引风基本没有阻挡作用，此时，引风量最大，如图2所示。导板410还可转动至完全关闭状态，此时，导板410与第一空调本体100和第二空调本体200的对称面垂直，将引风风道310和第一出风口103和第二出风口203隔离，贯通风道无法实现从后端引风口301的引风，如图3所示。参照图4，导板410可在完全打开状态和完全关闭状态之间转动，以实现引风量的动态调节；导板410可在完全打开状态和完全关闭状态之间定位，以实现从后端引风口301引入固定的引风量；当然，定位的角度可根据实际情况进行确定，以在不同定位位置实现不同的引风量。如图1所示，当导板410运动到送风风道320时，导板410可以通过调整其旋转角度，与第一出风口的第一导板107和第二出风口的第二导板207相互配合，调节出风风向。
导板410通过固定件420分别与第一驱动机构510和第二驱动机构520连接；固定件包括上连接板和下连接板，导板转动设置在上连接板和下连接板之间。
第二驱动机构包括第二电机和传动结构，传动结构包括齿轮齿条传动结构或蜗轮蜗杆传动结构。传动结构与上连接板或下连接板连接，驱动上连接板或下连接板前后运动。在其他的实施例中，可以设置两个传动结构，同时驱动上连接板和下连接板运动。
第一驱动机构包括第一电机，第一电机固定设置在上连接板或下连接板上，导板通过转轴与上连接板或下连接板连接。在本实施例中，驱动机构包括两个第一电机，两个第一电机分别固定设置在上连接板和下连接板上，导板410通过转轴分别与两个第一电机连接。
为了进一步提高引风效果，对贯通风道的结构进行优化设计，沿贯通风道的送风方向，贯通风道的内口径先减缩再渐扩。也即是，贯通风道的内口径先具有缩减的趋势而后具有扩大的趋势。其中，引风风道310的内口径减缩，送风风道320的内口径渐扩。第一出风口103和第二出风口203位于送风风道320的渐扩段，出风不会相互干扰，扩大了出风角度和送风距离。同时负压区形成在第一出风口103、第二出风口203和送风口303之间，在负压的作用下，外部空气经后端引风口301进入贯通风道，先经过渐缩通道再经过渐扩通道，使风速得以提高，提高引风效果。
本发明还包括一种双贯流空调室内机，包括上述的双贯流空调导板。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
