Description

壁挂式空调室内机 技术领域
本发明涉及空气调节技术领域，特别涉及一种壁挂式空调室内机。
背景技术
随着时代的发展和技术的进步，用户不仅期望空调具有更快的制冷和制热速度，还越来越关注空调的舒适性能。
然而，为了实现更加快速地制冷和制热，难免需要进行大风量送风。但是，当风速过大的冷风或热风直吹人体时，必然会引起人体的不适。人体长期被冷风直吹还会引发空调病。
因此，如何实现空调的舒适送风成为空调行业亟待解决的技术难题。
发明内容
本发明的目的是要提供一种克服上述问题或者至少部分地解决上述问题，提供一种制冷和制热可选用不同送风模式的壁挂式空调室内机。
本发明的目的是要使送风模式的切换更加方便、准确。
特别地，本发明提供了一种壁挂式空调室内机，其包括：
机壳，其开设有朝前下方敞开的出风口；
挡风罩，可上下平移地安装于所述机壳，其包括用于在所述出风口前侧遮挡所述出风口的竖挡板；和
导风板，可转动地安装于所述出风口处；
所述挡风罩和所述导风板具有联动关系，以共同运动至下吹状态或前吹状态；
在所述下吹状态下，所述导风板位于所述出风口前侧，所述竖挡板位于所述导风板前方，以共同引导气流向下流动；且
在所述前吹状态下，所述导风板位于所述出风口下侧，以引导气流向前流动，所述竖挡板的顶端与所述出风口上端具有间隔，以避开前吹的气流。
可选地，所述挡风罩和所述导风板配置成可运动至所述下吹状态和所述前吹状态之间的状态，以使所述出风口的气流同时朝前、朝下吹出。
可选地，所述导风板的端部设置有第一齿轮；且
所述挡风罩上形成有上下延伸的第一齿条，第一齿条与所述第一齿轮啮 合，以在所述挡风罩上下平移时，带动所述第一齿轮转动，从而带动所述导风板转动。
可选地，所述第一齿轮的数量为两个，且分别设置在所述导风板的长度方向的两端。
可选地，所述机壳内具有风道，其由前后间隔设置的前风道壁和后风道壁限定出，所述前风道壁和所述后风道壁的出口端分别与所述出风口的上端和下端相接，以用于将所述机壳内的气流导向所述出风口；且
在所述下吹状态下，所述导风板的一个端部抵靠于所述前风道壁；
在所述前吹状态下，所述导风板的另一端部抵靠于所述出风口下端。
可选地，所述导风板在处于所述前吹状态时的上表面为弧形，且弧形的前端切线朝前上方，以便引导气流上扬流动。
可选地，所述挡风罩还包括两个侧板，其分别从所述竖挡板的横向两端向后延伸出，两个所述侧板分别用于可上下平移地安装于所述机壳的横向两端部。
可选地，所述挡风罩还包括底板，所述底板的横向两边分别连接于两个所述侧板，且处于所述机壳的底壁下方；
所述底板开设有与所述出风口相对的出气口，以允许气流向下流出。
可选地，在所述下吹状态下，所述竖挡板的上端抵靠于所述出风口上端，且所述竖挡板和所述两个侧板的外表面与所述机壳的外表面平齐。
可选地，所述机壳的横向侧端具有安装板，其上设置有齿轮齿条机构，用于驱动所述挡风罩上下平移，其包括电机、相互啮合的第二齿轮和第二齿条；
所述电机设置于所述安装板内侧，所述第二齿轮安装于所述电机，所述第二齿条可上下平移地设置于所述安装板内侧，且其一部分通过所述安装板开设的竖直长条让位孔伸出至所述安装板外侧，并与所述侧板连接。
本发明的壁挂式空调室内机中，挡风罩可上下平移地设置在出风口处，导风板可转动地设置在出风口处，且挡风罩和导风板具有联动关系，以共同运动至下吹状态或前吹状态。在下吹状态下，导风板位于出风口前侧，竖挡板位于导风板前方，以共同引导气流向下流动。在前吹状态下，导风板位于出风口下侧，以引导气流向前流动，竖挡板下移至导风板正前方空间的下方，以避开前吹的气流。空调制冷时可选择前吹模式，使冷风送风距离更远，然 后在逐渐下沉，形成淋浴式制冷效果。空调制热时可选择下吹模式，使热风更容易抵达地面，实现地毯式送风效果，避免因热空气密度小导致热空气无法抵达地面，使室内底层空间得不到制热。
此外，由于挡风罩和导风板是联动的，无需设置两套驱动机构，只需要利用电机驱动其中一个即可，这简化了机壳内部结构。而且，联动相接也使得挡风罩和导风板的相对位置关系是被设定好的，能够更加精确地抵达前吹状态和下吹状态。

本发明实施例的提供了一种壁挂式空调室内机。壁挂式空调室内机为分体壁挂式房间空调器的室内部分，用于调节室内空气，例如制冷/制热、除湿和/或引入新风等等。
图1是根据本发明一个实施例的壁挂式空调室内机的结构示意图；图2是图1所示壁挂式空调室内机的剖视放大图；图3是图2所示壁挂式空调室内机在切换至前吹模式时的示意图。
如图1至图3所示，本发明实施例的壁挂式空调室内机一般性地可包括机壳10、挡风罩20和导风板30。机壳10开设有朝前下方敞开的出风口12。机壳10限定有用于容纳壁挂式空调室内机的各部件的容纳空间。出风口12可开设于机壳10的前侧下部，以便朝前下方敞开。出风口12用于将机壳10内的气流排向室内环境，以对室内空气进行调节。所排出的气流指的是被机壳10内的风机作用，以加速流过出风口12的、用于调节室内环境的气流，例如制冷模式下的冷风、制热模式下的热风和/或新风模式下的新风气流等等。机壳10可为长度方向(图1标示的横向方向)水平设置的长条状，出风口12可为长度方向平行于机壳10的长度方向的长条状，如图1。
挡风罩20可上下平移地安装于机壳10，挡风罩20包括用于在出风口12前侧遮挡出风口12的竖挡板21。挡风罩20运动至图2所示位置时，以便在出风口12的前侧遮蔽出风口12，使机壳10内的出风气流无法向前吹出。挡风罩20运动至图3所示位置时，远离出风口12的前侧，以不会阻碍出风气流正常向前或向前上方吹出。导风板30可转动地安装于出风口12处。具 体地，导风板30为长度方向平行于机壳10的长度方向的长条状，其转动轴线x平行于其长度方向。
挡风罩20和导风板30具有联动关系，以共同运动至图2所示的下吹状态或图3所示的前吹状态。
如图2所示，在下吹状态下，导风板30位于出风口12的前侧，竖挡板21位于导风板30前方，以共同引导气流向下流动。空调制热时可选择下吹模式，使热风更容易抵达地面，实现地毯式送风效果，避免因热空气密度小，导致室内底层空间得不到制热。
如图3所示，在前吹状态下，导风板30位于出风口12的下侧，以引导气流向前流动，竖挡板21的顶端与出风口12上端具有间隔，以便竖挡板21避开前吹的气流。空调制冷时可选择前吹模式，使冷风送风距离更远，然后在逐渐下沉，形成淋浴式制冷效果。
由于挡风罩20和导风板30是联动的，无需设置两套驱动机构，只需要利用电机71驱动其中一个即可，这简化了机壳10的内部结构。而且，联动相接也使得挡风罩20和导风板30的相对位置关系是被设定好的，能够更加精确地抵达前吹状态和下吹状态。
在一些实施例中，如图2和图3所示，机壳10内具有风道50，风道50由前后间隔设置的前风道壁200和后风道壁100限定出。前风道壁200和后风道壁100的出口端分别与出风口12的上端和下端相接，以用于将机壳10内的气流导向出风口12。机壳10的顶部开设有进风口11，轴线沿横向方向延伸的贯流风机40设置于风道50的进口处。三段式换热器60围绕在贯流风机40的上方。壁挂式空调室内机运行制冷模式或制热模式时，室内空气经进风口11进入机壳10的内部，与三段式换热器60完成换热，最后被贯流风机40吸入风道50中，流向出风口12。
在下吹状态下，导风板30的一个端部抵靠于前风道壁200，使沿着前风道壁200流动的气流能更好地过渡到导风板30上，接受导风板30的引导，减少流动损失。在前吹状态下。导风板30的另一端部抵靠于出风口12的下端，使沿着后风道壁100流动的气流能更好地过渡到导风板30上，接受导风板30的引导，减少流动损失。
在一些实施例中，如图3所示，导风板30在处于前吹状态时的上表面为弧形，且弧形的前端切线朝前上方，以便引导气流上扬流动，利于提高气 流的上扬角度，以便将冷风以更大的上扬角度(气流吹出角度与水平面的夹角)吹出，从而可达到躲避人体的目的，以上扬角度吹出的冷风达到最高点后向下散落，可实现淋浴式制冷体验。
图4是图2所示壁挂式空调室内机在切换至前吹模式与下吹模式之间的状态的示意图。
在一些实施例中，如图4所示，挡风罩20和导风板30配置成可运动至下吹状态和前吹状态之间的状态，以使出风口12的气流同时朝前、朝下吹出。
图5是图1中的挡风罩20的结构示意图。
在一些实施例中，如图1至图5所示，挡风罩20还包括两个侧板22，其分别从竖挡板21的横向两端向后延伸出，两个侧板22分别用于可上下平移地安装于机壳10的横向两侧部。设置两个侧板22，使挡风罩20两侧的外观更加美观，而且利于在机壳10横向端部设置连接和驱动结构。在下吹状态下，竖挡板21的上端抵靠于出风口12的上端，且竖挡板21和两个侧板22的外表面与机壳10的外表面平齐，以使挡风罩20与机壳10形成完整对接的外观效果。当壁挂式空调室内机处于非工作状态时，可使挡风罩20处于该状态，以使外观更加美观。
挡风罩20还包括底板23。底板23的横向两边分别连接两个侧板22，且处于机壳10的底壁下方。如此，使得挡风罩20的底部外观更加完整、美观。底板23开设有与出风口12相对的出气口230，以允许气流向下流出。即，机壳10内的出风气流向下流动时，需先流经出风口12，后经出气口230吹向室内环境。竖挡板21、底板23以及两个侧板22构成一体成型的整体件。
图6是壁挂式空调室内机的挡风罩20和导风板30的驱动机构示意图。
在一些实施例中，壁挂式空调室内机利用齿轮齿条机构实现导风板30与挡风罩20的联动。如图6所示，导风板30的端部设置有第一齿轮31，挡风罩20上形成有上下延伸的第一齿条211，其与第一齿轮31啮合，以在挡风罩20上下平移时，带动第一齿轮31转动，从而带动导风板30转动。具体地，可使第一齿轮31的数量为两个，两者分别设置在导风板30的长度方向的两端，以使导风板30两侧均受到扭矩，转动更加平稳。
图7是图6的另一角度的示意图。
在一些实施例中，壁挂式空调室内机利用齿轮齿条机构驱动挡风罩20 上下平移。如图6和图7所示，机壳10的横向两端部具有安装板13，安装板13上设置有齿轮齿条机构，用于驱动挡风罩20上下平移。安装板13具有多个耳板132，以便通过螺钉连接于机壳10的端盖。齿轮齿条机构包括电机71、相互啮合的第二齿轮72和第二齿条73。电机71设置于安装板13内侧，第二齿轮72安装于电机71，第二齿条73可上下平移地设置于安装板13内侧，且其一部分通过安装板13开设的竖直长条让位孔131伸出至安装板13外侧，并与挡风罩20的侧板22连接。
电机71带动第二齿轮72转动时，第二齿轮72带动第二齿条73上下平移，以驱动挡风罩20上下平移。
本实施例将齿轮齿条机构的主体结构安装于机壳10的横向侧端，不影响壁挂式空调室内机的外观。
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。
