可选地，所述内导风板为厚度均匀的弧形板，且具有首翼和尾翼，所述内导风板的弯曲程度由其首翼向其尾翼的方向逐渐或阶梯式地增大；且
所述内导风板在处于遮挡所述风口的状态时，其首翼位于其尾翼的前侧；所述内导风板在处于敞开所述风口的状态时，其首翼位于其尾翼的后侧。
可选地，所述内导风板的外表面沿外弧线由其首翼向其尾翼延伸，所述外弧线包括在由所述首翼向所述尾翼的方向上依次平滑连接的第一外圆弧、第二外圆弧和第三外圆弧；且
所述第一外圆弧所在圆的半径与所述第二外圆弧所在圆的半径之间的比值为范围在1.90～1.95之间的任一值；所述第二外圆弧所在圆的半径与所述第三外圆弧所在圆的半径之间的比值为范围在1.85～1.90之间的任一值。
可选地，所述内导风板的内表面沿内弧线由其首翼向其尾翼延伸，所述内弧线包括在由所述首翼向所述尾翼的方向上依次平滑连接的第一内圆弧、第二内圆弧和第三内圆弧；且
所述第一内圆弧所在圆的半径与所述第二内圆弧所在圆的半径之间的比值为范围在1.83～1.87之间的任一值；所述第二内圆弧所在圆的半径与所述第三内圆弧所在圆的半径之间的比值为范围在1.71～1.80之间的任一值。

进一步地，机壳内限定有微风风腔，微风风腔通过风口与出风风道连通，即微风口形成了微风风腔的气流出口，风口形成了微风风腔的气流入口。内导风板能够受控地遮挡风口或敞开风口。当内导风板转动至遮挡风口的状态时，可以阻止出风风道内的气流经风口流入微风风腔，避免气流从微风口流出；当内导风板转动至敞开风口的状态时，可以允许出风风道内的至少部分气流经风口流入微风风腔，从而经微风口流出。可见， 本发明利用内导风板转动过程中所处位置的不同实现了既能够与外导风板相配合调节出风口的出风方向的目的，又能够非常简便地控制微风口开闭的目的，无需设置诸如齿条、挡板等之类的部件，设计非常巧妙，简化了空调室内机的结构。

具体实施方式
现将详细参考本发明的实施例，其一个或多个示例在附图中示出。提供的各个实施例旨在解释本发明，而非限制本发明。事实上，在不脱离本发明的范围或精神的情况下对本发明进行各种修改和变化对于本领域的技术人员来说是显而易见的。例如，图示或描述为一个实施例的一部分的特征可以与另一个实施例一起使用以产生再另外的实施例。因此，本发明旨在涵盖所附权利要求书及其等同物范围内的此类修改和变化。
本发明提供一种空调室内机，图1是根据本发明一个实施例的空调室内机的示意性剖视图。参见图1，空调室内机1包括机壳10，机壳10具有用于供气流流入其中的进风口11、位于其底部前侧以供气流流出的出风口12以及位于其前侧下部以供气流流出的微风口13。机壳10的位于出风口12的内侧形成有出风风道14。具体地，进风口11可形成在机壳10的顶部，以使得空调室内机1从顶部进风、从底部和/或前侧下部出风。
进一步地，空调室内机1还包括位于机壳10内的换热器20和气流驱动装置30。换热器20用于与流经其的气流进行热交换。气流驱动装置30用于驱动气流从进风口11流向出风口12和/或微风口13。换热器20位于进风口11至气流驱动装置30之间的气流流动路径上。具体地，气流驱动装置30可以为风机，例如在图1所示实施例中，气流驱动 装置30为贯流风机。出风风道14与风机的出风口连通。
特别地，空调室内机1还包括外导风板40和内导风板50。外导风板40可转动地设置于出风口12处，以受控地调节出风口12的开闭和出风方向。内导风板50可转动地设置于出风风道14内，以受控地将出风风道14内的气流送往微风口13和/或出风口12，并调节气流流向出风口12的流向。也就是说，可以通过外导风板40转动位置的改变选择性地打开出风口12或关闭出风口12，还可以通过外导风板40转动位置的改变调节出风口12的出风方向。内导风板50可转动地设置于外导风板40的内侧，可以通过其转动位置的改变选择性地将出风风道14内的气流送往微风口13、出风口12或者同时送往微风口13和出风口12，并且通过内导风板50转动位置的改变还可以调节气流流向出风口12的流向，从而调节出风口12的出风方向。
本发明的空调室内机1除了具有传统的底部出风口之外，还在其机壳10前侧下方特别设计微风口13；除了具有传统的外导风板40之外，还在位于外导风板40内侧的出风风道14内特别设计可转动的内导风板50。外导风板40可以调节出风口12的开闭和出风方向，内导风板50可以选择性地将出风风道14内的气流送往微风口13和/或出风口12，并调节气流流向出风口12的流向。由此，内导风板50和外导风板40可具有多种位置状态组合，可以通过内导风板50和外导风板40的配合实现空调室内机1的常规制冷、常规制热、冷风上扬、无风感舒适、垂直下吹等多种送风模式，满足了用户多样化的送风需求，提高了用户的使用体验。
进一步地，微风口13可包括紧密排列的多个细小的通风孔。由于通风孔的尺寸较小，且排列紧密，气流经微风口13的多个通风孔流出时，送风非常柔和、舒适，实现了微风舒适送风或者完全无风感舒适送风的目的。
在一个具体实施例中，微风口13可包括上下排列的多个条形的狭长通风孔，每个狭长通风孔均沿机壳10的横向延伸。
在另一个具体实施例中，微风口13可包括沿机壳10的横向排列的多个条形的狭长通风孔，每个狭长通风孔均沿上下方向延伸。
在又一个具体实施例中，微风口13可包括均匀分布的多个圆形通风孔。
在一些实施例中，机壳10内限定有微风风腔15，微风口13与微风风腔15连通，微风风腔15通过风口611与出风风道14连通，从而间接地连通了出风风道14和微风口13。
进一步地，内导风板50配置成受控地遮挡风口611以阻止出风风道14内的气流经风口611流入微风风腔15或敞开风口611以允许出风风道14内的气流经风口611流入微风风腔15并经微风口13流出。
也就是说，微风口13形成了微风风腔15的气流出口，风口611形成了微风风腔15的气流入口。内导风板50能够受控地遮挡风口611或敞开风口611。当内导风板50转动至遮挡风口611的状态时，可以阻止出风风道14内的气流经风口611流入微风风腔15，避免气流从微风口13流出；当内导风板50转动至敞开风口611的状态时，可以允许出风风道14内的至少部分气流经风口611流入微风风腔15，从而经微风口13流出。可见，本发明利用内导风板50转动过程中所处位置的不同实现了既能够与外导风板40相配合 调节出风口12的出风方向、又能够非常简便地控制微风口13开闭的目的，无需设置诸如齿条、挡板等之类的部件，设计非常巧妙，简化了空调室内机1的结构。
在一些实施例中，出风风道14由位于其前侧上部的前蜗壳61和位于其后侧下部的后蜗壳62以及位于其横向两侧的两个端板(图中未示出)限定而成。风口611开设在前蜗壳61上，内导风板50在处于遮挡风口611的状态时，其至少部分外表面与前蜗壳61的处于风口611后侧的表面相贴合。也就是说，出风风道14和风口611分别处在内导风板50的两侧，且内导风板50与前蜗壳61的表面之间没有允许气流通过的间隙。一方面，当出风风道14内的气流由后向前流动遇到内导风板50后，在内导风板50的阻挡下不会继续流向位于内导风板50另一侧的风口611，避免了气流经微风口13吹出；另一方面，还可以通过内导风板50在出风风道14内形成促使气流流向出风口12的弧形风道，以尽可能地减小内导风板50对气流产生的阻力。可见，本发明通过内导风板50与前蜗壳61的结构配合实现了打开或关闭微风口13的目的，设计非常巧妙。
在一些实施例中，风口611从后往前地水平贯穿前蜗壳61；或者，风口611从后往前地向上倾斜贯穿前蜗壳61，以减小气流流经风口611时的阻力，尽可能地保持较大的流速。
进一步地，风口611为沿机壳10的横向延伸的条形风口，以便于使得气流充满整个微风风腔15，防止微风风腔15的部分区域出现负压导致倒流现象。
在一些实施例中，内导风板50为厚度均匀的弧形板，且具有首翼51和尾翼52，内导风板50的弯曲程度由其首翼51向其尾翼52的方向逐渐或阶梯式地增大。也就是说，内导风板50靠近其尾翼52的区段弯曲程度最大，比较适合改变气流流向；内导风板50靠近其首翼51的区段弯曲程度最小，过度最平缓，对气流的阻力越小。
进一步地，内导风板50在处于遮挡风口611的状态时，其首翼51位于其尾翼52的前侧，即出风风道14内的由后向前流动的气流先接触内导风板50的尾翼52，然后再接触内导风板50的首翼51，以便有效地改变气流流向，促使出风风道14内的气流全部流向出风口12。内导风板50在处于敞开风口611的状态时，其首翼51位于其尾翼52的后侧，即出风风道14内的由后向前流动的气流先接触内导风板50的首翼51，然后再接触内导风板50的尾翼52，以循序渐进地调整气流的方向，减小气流阻力。
本发明的空调室内机1通过内导风板50和外导风板40的配合可以实现常规制冷、常规制热、冷风上扬、无风感舒适、垂直下吹等多种送风模式。下面以具体的实施例说明内导风板50和外导风板40的多种组合状态。
图1中，空调室内机1处于停机状态，此时外导风板40处于关闭出风口12的位置。
图2是根据本发明一个实施例的空调室内机处于冷风上扬状态下的示意性剖视图，图中的虚线箭头表示气流的大致流向。在冷风上扬状态下，外导风板40转动至大致水平的位置，内导风板50转动至其尾翼52向上倾斜15°左右的位置。此时，在气流驱动装置30的驱动下，经换热器20换热后的气流在内导风板50的引导下分流至微风风腔15和出风口12，流向微风风腔15的气流经微风口13水平地向前吹出，流向出风口12的气流在外导风板40的进一步引导下略向前上方送出，实现了冷风上扬不直吹人体的舒适效 果。
图3是根据本发明一个实施例的空调室内机处于微风舒适状态或无风感舒适状态下的示意性剖视图，图中的虚线箭头表示气流的大致流向。在微风舒适状态或无风感舒适状态下，外导风板40转动至关闭出风口12的闭合位置，内导风板50转动至向上倾斜40°左右的位置。此时，在气流驱动装置30的驱动下，经换热器20换热后的气流在内导风板50的引导下几乎全部流向微风风腔15，即使部分气流继续流向出风口12也会在外导风板40的引导下再流向微风风腔15。由此，全部气流均通过微风口13送出，实现了微风送风或无风感送风的舒适送风效果。
图4是根据本发明一个实施例的空调室内机处于常规制冷状态下的示意性剖视图，图中的虚线箭头表示气流的大致流向。在常规制冷状态下，外导风板40处于完全打开出风口12的状态，不会气流产生任何阻碍作用。内导风板50可在第一角度范围内来回转动，在气流驱动装置30的驱动下，经换热器20换热后的气流会按照可调的流量比分流到微风风腔15和出风口12，从而经微风口13和出风口12送出，实现了朝向机壳10前方和前下方吹风的常规制冷送风效果。
图5是根据本发明一个实施例的空调室内机处于垂直下吹状态下的示意性剖视图，图中的虚线箭头表示气流的大致流向。在垂直下吹状态下，外导风板40处于完全打开出风口12的状态，不会气流产生任何阻碍作用。内导风板50转动至使其尾翼52与前蜗壳61的位于风口611后侧的表面区域相贴合的位置，此时，内导风板50完全遮挡风口611，相当于关闭了微风口13。在气流驱动装置30的驱动下，经换热器20换热后的气流在内导风板50的引导下全部流向出风口12，并几乎垂直地经出风口12向下送出，实现了热风垂降暖足的送风效果。
图6是根据本发明一个实施例的空调室内机处于常规制热状态下的示意性剖视图，图中的虚线箭头表示气流的大致流向。在常规制热状态下，外导风板40处于完全打开出风口12的状态，不会气流产生任何阻碍作用。内导风板50可在第二角度范围内来回转动，以将换热后的全部或大部分热风引导至出风口12，从而尽可能地朝机壳10的前下方送风，实现了常规的制热送风效果。
可以理解的是，内导风板50和外导风板40的组合状态并不限制为以上几种，还可以有其他更多可能的组合状态，这里不再一一举例说明。
还可以理解的是，内导风板50具有内表面和外表面。图7是根据本发明一个实施例的内导风板的示意性剖视图，图8是根据本发明一个实施例的内导风板外表面的具体形状划分示意图。在一些实施例中，内导风板50的外表面沿外弧线53由其首翼51向其尾翼52延伸，外弧线53包括在由首翼51向尾翼52的方向上依次平滑连接的第一外圆弧531、第二外圆弧532和第三外圆弧533。
进一步地，第一外圆弧531所在圆的半径R1与第二外圆弧532所在圆的半径R2之间的比值为范围在1.90～1.95之间的任一值；第二外圆弧532所在圆的半径R2与第三外圆弧533所在圆的半径R3之间的比值为范围在1.85～1.90之间的任一值。由此，外弧线53的各个圆弧之间的连接过度更加平稳和光滑，可以保证内导风板50的外表面更加光 滑。当内导风板50处于遮挡风口611的状态时，能够确保内导风板50的外表面尽可能紧密地贴合于前蜗壳61，避免漏风的可能性，同时确保内导风板50具有合适的向下弯曲角度以更好地将气流引导至出风口12。
具体地，第一外圆弧531所在圆的半径R1与第二外圆弧532所在圆的半径R2之间的比值例如可以为1.90、1.91、1.92、1.93、1.94或1.95。第二外圆弧532所在圆的半径R2与第三外圆弧533所在圆的半径R3之间的比值例如可以为1.85、1.86、1.87、1.88、1.89或1.90。
在一些实施例中，参见图9所示的根据本发明一个实施例的内导风板内表面的具体形状划分示意图。内导风板50的内表面沿内弧线54由其首翼51向其尾翼52延伸，内弧线54包括在由首翼51向尾翼52的方向上依次平滑连接的第一内圆弧541、第二内圆弧542和第三内圆弧543。
进一步地，第一内圆弧541所在圆的半径r1与第二内圆弧542所在圆的半径r2之间的比值为范围在1.83～1.87之间的任一值；第二内圆弧542所在圆的半径r2与第三内圆弧543所在圆的半径r3之间的比值为范围在1.71～1.80之间的任一值。由此，内弧线54的各个圆弧之间的连接过度更加平稳和光滑，可以保证内导风板50的内表面更加光滑，从而减小气流流经内导风板50时的阻力。
具体地，第一内圆弧541所在圆的半径r1与第二内圆弧542所在圆的半径r2之间的比值例如可以为1.83、1.84、1.85、1.86或1.87。第二内圆弧542所在圆的半径r2与第三内圆弧543所在圆的半径r3之间的比值例如可以为1.71、1.72、1.73、1.74、1.75、1.76、1.77、1.78、1.79或1.80。
图10是根据本发明一个实施例的空调室内机的部分尺寸标注图。在一些实施例中，内导风板50的转轴55在竖直方向上与前蜗壳61之间的距离W1为机壳10在竖直方向上的整体高度H的0.05～0.10倍。具体地，内导风板50的转轴55在竖直方向上与前蜗壳61之间的距离W1例如可以为机壳10在竖直方向上的整体高度H的0.05倍、0.06倍、0.07倍、0.08倍、0.09倍或0.10倍。由此，可以在内导风板50与前蜗壳61之间保持合适的距离，使得内导风板50能够与前蜗壳61的位于风口611后侧的表面贴合，从而达到遮挡风口611的目的。若W1设置的过小，内导风板50与前蜗壳61的接触位置可能会处在风口611之前或处在风口611中，无法达到遮挡风口611的目的。若W1设置的过大，内导风板50可能根本无法接触到前蜗壳61，也根本达不到遮挡风口611的目的。
在一些实施例中，机壳10具有位于其前侧的前面板16，前面板16的板体沿竖直方向延伸，风口611形成在前面板16上。内导风板50的转轴55在水平方向上与前面板16之间的距离W2为机壳10在竖直方向上的整体高度H的0.20～0.24倍。具体地，内导风板50的转轴55在水平方向上与前面板16之间的距离W2例如可以为机壳10在竖直方向上的整体高度H的0.20倍、0.21倍、0.22倍、0.23倍或0.24倍。由此，便于在内导风板50与前蜗壳61之间保持合适的距离，使得内导风板50能够与前蜗壳61的位于风口611后侧的表面贴合，从而达到遮挡风口611的目的。若W2设置的过小，内导风板50的转轴55过于靠前，根本无法遮挡风口611；若W2设置的过大，内导风板50的转轴 55过于靠后，无法更加有效地调节气流流向，并且内导风板50在出风风道14内的转动范围会受到较大的限制，甚至会与前蜗壳61和/或后蜗壳62产生结构干涉。
本发明通过对内导风板50的内表面和外表面的具体形状和尺寸、以及内导风板50的转轴55的位置进行上述特别的限定，可以在内导风板50能够有效导风的同时，确保空调室内机1在垂直下吹状态时，内导风板50遮挡风口611的同时，邻近其首翼51区段恰好能够将气流垂直地向下引导，实现了较佳的垂降效果。
在一些实施例中，参见图9，首翼51与尾翼52之间的连线形成内导风板50的线性长度L，内导风板50的线性长度L为机壳10在竖直方向上的整体高度H的0.17～0.20倍。具体地，内导风板50的线性长度L1例如可以为机壳10在竖直方向上的整体高度H的0.17倍、0.18倍、0.19倍或0.20倍。由此，既能够确保内导风板50具有足够长的长度以有效地引导出风风道14内的气流流动，又可避免内导风板50过长导致其与前蜗壳61和/或后蜗壳62产生结构干涉。
在一些实施例中，微风口13在竖直方向上延伸的高度H1为机壳10在竖直方向上的整体高度H的0.05～0.08倍。具体地，微风口13在竖直方向上的高度H1例如可以为机壳10在竖直方向上的整体高度H的0.05倍、0.06倍、0.07倍或0.08。由此，既能够起到明显的微风送风效果，又不会产生回流现象。若H1设置的过小，显然不足以起到明显的送风效果；若H1设置的过大，微风风腔15内无法形成足够的风压使气流充满整个微风风腔15，微风口13的局部区域可能没有气流流出或者气流较少，外部空气可能会经该局部区域流入微风风腔15内部产生倒流现象，进而会在微风风腔15内形成凝露。
本领域技术人员还应理解，本发明实施例中所称的“上”、“下”、“前”、“后”、“顶”、“底”等用于表示方位或位置关系的用语是以空调室内机1的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或不见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发明的限制。
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。
