本发明的导流板包括第一导流部和导流面不同于第一导流部的第二导流部，不仅增大了室内机的有效导流面积，提高了导流效果，而且通过使导流板绕水平方向转动，可调节气体流过第一导流部和第二导流部的顺序、以 及位于下游的第一导流部或第二导流部的导风角度，进而实现多种送风角度和送风扬程的组合，提高了用户体验。
进一步地，采用本发明的方案，在制冷状态下，使导流板转动至使气体先流过直线延伸的第一导流部后流过弧线延伸的第二导流部，并使第二导流部的导流方向倾斜向上，可使导流板上方的空气在极短的距离内迅速达到升空所需的角度和速度，增大室内机的送风扬程，避免冷空气直吹人体；在制热状态下，使导流板转动至使空气先流过弧线延伸的第二导流部后流过直线延伸的第一导流部，并使第一导流部的导流方向倾斜向下，提高气体的流速和送风距离，使室内环境的下层空间快速升温。
进一步地，本发明的导流板还设置有自第二导流部靠近第一导流部的一端向远离第一导流部的方向延伸的第三导流部，并使第三导流部在制冷状态下向下倾斜延伸，在部分空气被第二导流部导流上扬的同时，使另一部分空气从与主风道的风道后壁基本相配的第三导流部的下方流出，这可在制冷状态时增大主风道的送风范围，保证主风道的送风风量和气流流速。

具体实施方式
图2是根据本发明一个实施例的空调室内机200的示意性剖视图。参见图2，空调室内机200可包括机壳210、设置于机壳210内的风机220和换热器230。空调室内机200可为壁挂式空调室内机。
机壳210可包括用于支撑风机220和换热器230的骨架、罩设在骨架上的罩壳、连接在罩壳的前侧以用于构成机壳210前部的面板以及分别设置于机壳210两侧的左端盖和右端盖。
罩壳可具有位于其顶部的进风口211和位于其底部的出风口212。进风口211处可设置有进风格栅，室内空气由进风格栅进入室内机200内部。连通进风口211和出风口212的主风道213可部分由骨架形成。
风机220可促使空气自进风口211流向出风口212。换热器230可设置于进风口211与出风口212之间的气体流路上，以与流经进风口211和出风口212之间的室内空气进行热交换。换热器230可设置于风机220的上游，以降低风阻。
在一些实施例中，罩壳可设置为向前拱起，以在前侧增大与换热器230的间隔，进而提高空调室内机200的送风量。
出风口212处可设置有可绕水平方向转动的导风板240，以在竖直方向上调整气流的流动方向。出风口212处可设置有可横向摆动的摆叶245，以在横向方向上调整气流的流动方向。
图3是根据本发明另一个实施例的空调室内机200的示意性剖视图，其中，空调室内机200处于制冷模式；图4是图3中区域A的示意性放大视图。参见图3和图4，本实施例与前述实施例(图2)的一个区别为在风机220的送风流路上增设导流板250。
特别地，导流板250可包括第一导流部251和第二导流部252。导流板250配置为可绕水平方向转动，以调节气体流过第一导流部251和第二导流部252的顺序、以及位于下游的第一导流部251或第二导流部252的导流角度。
本发明的导流板250包括第一导流部251和导流面不同于第一导流部251的第二导流部252，不仅增大了室内机200的有效导流面积，提高了导流效果，而且通过使导流板250绕水平方向转动，可调节气体流过第一导流部251和第二导流部252的顺序、以及位于下游的第一导流部251或第二导流部252的导风角度，进而实现多种送风角度和送风扬程的组合，提高了用户体验。“水平方向”可平行于机壳210的横向延伸方向。在一些实施例中，导流板250可绕沿水平方向延伸的转轴转动。例如，导流板250与转轴固定连接，并且转轴可以连接至驱动电机的输出轴。
在一些进一步的实施例中，上述转轴可由另外的驱动机构带动进行移动，以调整转轴的工作位置，从而实现多种送风角度和送风扬程的组合。该驱动机构可为电机、齿轮和/或齿条的组合。
在一些实施例中，第一导流部251可设置为直线延伸。第二导流部252可设置为弧线延伸，以实现更多种可能的角度调节。即，第一导流部251为平板状，第二导流部252为弧形板状。“沿直线延伸”以及“沿弧线延伸”分别是针对第一导流部251和第二导流部252以及下述第三导流部253的横截面的延伸方向进行描述。
第二导流部252的靠近第一导流部251的一端与远离第一导流部251的一端的连接平面与第一导流部251的夹角α可为25°～40°，以使气体的流动更加顺畅，并提高导流板250的结构强度。第二导流部252自第一导流部251的一端沿弧线、且朝向远离第一导流部251的方向延伸，以形成与第一导流部251相接的弧形板。例如，夹角α可为25°、36°、或40°。
导流板250可设置为在换热器230处于制冷状态下，转动至使气体先流过第一导流部251并后流过第二导流部252，并使第二导流部252的远离第 一导流部251的一端的导流方向倾斜向上，以使导流板250上方的空气在极短的距离内迅速达到升空所需的角度和速度，增大室内机200的送风扬程，避免冷空气直吹人体。
在一些进一步地实施例中，导流板250还可包括第三导流部253。第三导流部253可设置为自第二导流部252的靠近第一导流部251的一端向远离第一导流部251的方向延伸，并在换热器230处于制冷状态下向下倾斜延伸，以提高导流板250的结构强度，避免第二导流部252本身在气流流过时产生振动，并在部分空气被第二导流部252导流上扬的同时，使另一部分空气从与主风道213的风道后壁基本相配的第三导流部253的下方流出，在制冷状态时增大主风道213的送风范围，保证主风道213的送风风量和气流流速。
第二导流部252在第一导流部251的延伸方向上的尺寸可与第一导流部251在其延伸方向上的尺寸L 1基本相等。第三导流部253在第一导流部251的延伸方向上的尺寸L 3可与第一导流部251在其延伸方向上的尺寸L 1基本相等，以进一步地提高导流板250的结构强度，提高从第三导流部253的下方流出的气流的流速。
第一导流部251和第三导流部253可设置为直线延伸并且共线，以提高从第三导流部253的下方流出气流的流动顺畅性。上述“共线”是指第一导流部251的横截面和第三导流部253的横截面共线，第一导流部251和第三导流部253的整体可呈平板状。
导流板250可设置在机壳210的主风道213内。第一导流部251和第三导流部253与主风道213的后壁的最小间距D可大于等于第一导流部251或第三导流部253在其延伸方向上的尺寸L 1或L 3，以提高导流板250的可转动角度范围。
第二导流部252在换热器230处于制冷状态下时的延伸平面可不高于机壳210的前面板的底端，以避免前面板凝露。
图5是图3所示空调室内机200的另一示意性剖视图，其中，空调室内机200处于制热模式。参见图5，导流板250可设置为在换热器230处于制热状态下，转动至使气体先流过第二导流部252而后流过第一导流部251，并使第一导流部251的远离第二导流部252的一端的导流方向倾斜向下，以提高气体的流速和送风距离，使室内环境的下层空间快速升温。
图6是图3所示空调室内机200的又一示意性剖视图，其中，空调室内 机200处于不吹人模式。参见图6，机壳210的底部可开设有分流风道214。分流风道214的气流入口可设置为与机壳210的主风道213连通、气流出口可位于出风口212的后侧并开口向下，以将主风道213内的气流全部或部分分流至分流风道214，减小由主风道213吹出气流的流速和风量，减小或避免气流直吹人体的问题。气流出口可为多个贯穿孔215，以实现无风感送风。
分流风道214的气流入口处可设置有挡板260。挡板260设置为可旋转开闭气流出口，以导通分流风道214或阻断分流风道214。挡板260可设置为绕其中部转动。
在图6实施例中，导风板240处于关闭状态，挡板260处于打开状态，换热空气全部经由分流风道214的气流出口流出。导流板250可转动至将主风道213内上部的空气导流至分流风道214的气流入口的下部，以使气流出口出风均匀。
图7是对图1所示空调室内机100进行测试测得的流场图，其中，导流板基本与主风道的导流方向相同；图8是对图3所示空调室内机200进行测试测得的流场图，其中，导流板250基本与主风道213的导流方向相同。从图7和图8的测试结果可以看出，在其他条件相同的情况下，罩壳向前拱起相比于罩壳前壁贴近换热器可显著地提高空调室内机的送风量。
图9是对图1所示空调室内机100进行测试测得的流场图，其中，导流板处于向上转动的极限位置；图10是对图3所示空调室内机200进行测试测得的流场图，其中，导流板250处于向上转动的极限位置。从图9和图10的测试结果可以看出，在其他条件相同的情况下，采用平板状的导流板最高可将气流导向水平向下15°左右，而采用本发明实施例的导流板250导出的气流可实现几乎水平吹出，具有更好的制冷效果。
图11是对图1所示空调室内机100进行测试测得的流场图，其中，导流板处于向下转动的极限位置；图12是对图3所示空调室内机200进行测试测得的流场图，其中，导流板250处于向下转动的极限位置。从图11和图12的测试结果可以看出，在其他条件相同的情况下，采用平板状的导流板最低可将气流导向水平向下60°左右，而采用本发明实施例的导流板250最低可将气流导向水平向下65°左右且气体流速更快，具有更好的制热效果。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根 据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
