Description

空调室内机及其导风筒 技术领域
本发明涉及空气调节技术领域，特别涉及一种空调室内机及其导风筒。
背景技术
随着空调技术的发展，空调室内机的外形和功能不断更新换代，各种新技术层出不尽。
但是，关于空调室内机的导风结构的创新结构非常少。现有方案通常都是在出风口处设置导风板和摆叶组，通过导风板调节出风口的一个方向维度的角度，通过摆叶进行另一方向维度的摆风。现有空调室内机大量采用上述导风结构，在使用体验和产品外观上趋于一致，难以提升产品档次。
因此，如何在导风结构方面实现创新成为空调行业亟待解决的技术难题。
发明内容
本发明的一个目的是要提供一种新型的导风筒及具有其的空调室内机，以提升产品的区分度和用户的使用体验。
本发明的另一目的是要解决出风气流的方向引导和微风效果不能兼顾的问题。
一方面，本发明提供了一种用于空调室内机的导风筒，所述导风筒用于可绕平行于其长度方向的轴线转动地安装于所述空调室内机的出风口处；且
所述导风筒的周壁包括沿其周向排列的导风段和通风段，以便允许所述出风口处的出风气流先经所述通风段的部分区域进入所述导风筒内部，接受所述导风段的内壁的引导，再经所述通风段的其余区域吹向室内环境。
可选地，所述通风段为开设有多个散风孔的板状。
可选地，每个所述散风孔为长度方向平行于所述导风筒长度方向的长条孔，且各所述散风孔沿所述导风筒的周向依次间隔排列。
可选地，任一所述散风孔的宽度为m，该散风孔与任一相邻散风孔之间所间隔的实体部分的宽度为n；满足：1.8≤m/n≤2.2。
可选地，所述导风段的内壁为母线平行于所述导风筒长度方向的内凹弯曲面。
可选地，所述导风筒为圆筒状，其转动轴线与圆筒的中心轴线重合。
可选地，所述导风筒为正多棱柱状，其转动轴线与多棱柱的中心轴线重合。
可选地，所述导风筒为正六棱柱状，其六个外侧面中的两个构成所述导风段的外表面。
另一方面，本发明提供了一种空调室内机，其包括：
壳体，其开设有出风口；和
如以上任一项所述的导风筒，其设置在所述出风口处。
可选地，所述空调室内机为壁挂式空调室内机，所述出风口为长度方向平行于水平横向的长条状，且开设于所述壳体的前侧下部；且
所述导风筒与所述出风口的下端具有间隔，所述空调室内机还包括导风板，所述导风板可转动地设置在所述导风筒与所述出风口的下端之间的间隔处。
本发明的空调室内机及其导风筒中，导风筒为筒状，相比于传统的导风板，结构更加新颖独特。导风筒的周壁包括沿其周向排列的导风段和通风段。空调室内机运行时，出风气流先经通风段的部分区域进入导风筒内部，然后接受导风段的内壁的引导，再经通风段的其余区域吹向室内环境。在此过程中，出风气流两次经过通风段，经历两次打散，且在导风筒内部进行一次周转盘旋，进一步加强了其柔和性，使得气流噪音更低，风感更加柔软。使空调室内机营造出一种静谧舒适的送风环境，使人体感觉更加舒适。
并且，本发明的导风筒不仅将出风气流柔化处理，而且还特别利用导风段的内壁进行导风，利用导风段发挥传统的导风板的作用，使得出风气流的指向性更强。本发明的导风筒兼顾了出风气流的方向引导和微风效果，结构既简单又巧妙。
进一步地，本发明中，若空调室内机为壁挂式空调室内机，特别使导风筒与出风口的下端具有间隔，且在此间隔处设置导风板，以便允许部分出风气流不经柔化处理直接向下吹出。从而在空调室内机制热时，加强制热下吹能力，使热风更好地抵达地面，避免常常出现的脚冷问题。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

本发明实施例一方面提供了一种导风筒20，用于安装于空调室内机的出风口12处，以引导出风口12处的出风方向。本发明实施例所述的空调室内机为空调的室内部分，用于调节室内空气，例如制冷/制热、除湿、净化、引入新风等等。本发明对空调室内机的样式不做限定，可以为壁挂式、立式、吊顶式等等，图1至图8示意的是壁挂式空调室内机的实施例，其他各种形式的空调室内机的实施例不进行赘述。
图1是本发明一个实施例的空调室内机结构示意图；图2是图1所示空调室内机的C-C剖视放大图；图3是图2中的导风筒20的放大图；图4是图2所示空调室内机运行上吹模式时的示意图。图中用箭头示意了气流的流动方向。
如图1至图4所示，本发明实施例的导风筒20为筒状，其具有长度方向。导风筒20用于可绕平行于其长度方向的轴线x转动地安装于空调室内机的出风口12处，以便引导出风口12处的出风方向。
并且，导风筒20的周壁包括沿其周向排列的导风段21和通风段22，也就是说，导风段21和通风段22属于导风筒20周壁的两个区段。如此设置，以便允许出风口12处的出风气流先经通风段22的部分区域进入导风筒20内部，接受导风段21的内壁211的引导，再经通风段22的其余区域吹向室内环境。
当然，导风筒20还可包括两个端壁(未图示)，两个端壁与周壁共同限定出导风筒20的内部空腔。空调室内机可包括电机，电机的转轴连接于一个端壁，以用于驱动导风筒20绕x轴转动。电机可为步进电机。可使电机与空调室内机的控制器电连接，以便受控制器的控制。
本发明实施例的空调室内机及其导风筒20中，导风筒20为筒状，相比 于传统的导风板50，结构更加新颖独特。并且，导风筒20的周壁包括沿其周向排列的导风段21和通风段22。空调室内机运行时，出风气流先经通风段22的部分区域进入导风筒20内部，然后接受导风段21的内壁211的引导，再经通风段22的其余区域吹向室内环境，如图4。在此过程中，出风气流两次经过通风段22，经历两次打散，且在导风筒20内部进行一次周转盘旋，进一步加强了其柔和性，使得气流噪音更低，风感更加柔软。使空调室内机营造出一种静谧舒适的送风环境，使人体感觉更加舒适。
现有技术存在一些在壳体或者导风板上开设微孔，以实现微孔送风效果的方案。但是，这些方案中，气流吹出后的方向得不到引导，使得出风的指向性不好。本发明实施例的导风筒20不仅将出风气流柔化处理，而且还特别利用导风段21的内壁211进行导风，利用导风段21发挥传统的导风板50的作用，使得出风气流的指向性更强。本发明的导风筒20兼顾了出风气流的方向引导和微风效果，结构既简单又巧妙。
在本发明的一些实施例中，如图3所示，可使通风段22为开设有多个散风孔222的板状。具体地，可使每个散风孔222为长度方向平行于导风筒20长度方向的长条孔，且各散风孔222沿导风筒20的周向依次间隔排列。相比于矩阵式排列的圆孔或方孔，这种长条孔的通风面积要更大，以避免通风面积过小导致出风不畅，从而影响空调室内机的制冷/制热效率。可使每个散风孔222的长度方向的两端分别延伸至邻近导风筒20的长度方向的两端的位置，使其长度能够覆盖出风口12的整个长度方向。
在一些实施例中，如图3所示，可使任一散风孔222的宽度为m，该散风孔222与任一相邻散风孔222之间所间隔的实体部分的宽度为n；满足：1.8≤m/n≤2.2。优选地，使1.9≤m/n≤2.1，例如使m/n＝2。如此可实现出风畅快性与柔和性的平衡。各个散风孔222的宽度m可相同，也可不同。各实体部分的宽度n可相同，也可不同。优选地，使各个散风孔222的宽度m相同，各实体部分的宽度n相同。
在一些实施例中，如图3所示，导风段21的内壁211为母线平行于导风筒20长度方向的内凹弯曲面。如此设置，可使内壁211能更好地引导风向，使得气流的转向更加平缓。例如，可使导风板50的内壁211为中心轴线平行于导风筒20长度方向的弧面。进一步可使其中心轴线与导风筒20的转动轴线x重合。
在一些实施例中，如图2至图4所示，可使导风筒20为圆筒状，其转动轴线与圆筒的中心轴线重合。并且，导风段21所占据的圆心角a的范围在110°至130°之间，例如使a＝120°。
在另一些实施例中，参考图8，导风筒20可为正多棱柱状，其转动轴线与多棱柱的中心轴线x重合。当然，本实施例并非严格限定导风筒20为几何意义的正多棱柱，其每个侧面并非必须平面，也可为内凹或外凸的曲面，只要整体大致为正多棱柱即可落入本发明实施例的保护范围。例如图8所示，可使导风筒20为正六棱柱状，其六个外侧面中的两个构成导风段21的外表面，且该两个外侧面对应的内侧面为一个整体的圆弧面，构成导风段21的内壁211。
本发明实施例另一方面提供了一种空调室内机。如图1至图4所示，空调室内机一般性地可包括壳体10和如以上任一项的导风筒20。
壳体10限定有用于容纳空调室内机的各部件的容纳空间，壳体10内部形成用于调节室内环境的气流。例如制冷模式下的冷风、制热模式下的热风以及新风模式下的新风气流等等。壳体10开设有出风口12，用于引出壳体10内的气流。
空调室内机可为各种形式，例如图1至图4所示，空调室内机为壁挂式空调室内机，出风口12为长度方向平行于水平横向的长条状，且开设于壳体10的前侧下部。导风筒20的长度方向平行于出风口12的长度方向。
在一些实施例中，如图2和图4所示，导风筒20与出风口12的下端B具有间隔，以便允许部分出风气流不经柔化处理直接向下吹出。从而在空调室内机制热时，加强制热下吹能力，使热风更好地抵达地面，避免常常出现的脚冷问题。空调室内机还包括导风板50，导风板50可转动地设置在导风筒20与出风口12的下端之间的间隔处，以用于开闭该间隔，以及引导该间隔处的出风方向。导风板50的转动轴线为y。
在一些实施例中，如图2所示，可使空调室内机还包括风道60。风道60的出口连通出风口12。风道60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的邻近出风口12的区段为内凹段230(CA段)，以便给导风筒20让位，避免干涉。具体地，内凹段230可为以导风筒20的转动轴线为轴的圆弧。
本发明实施例的空调室内机具有多种送风模式。
图5是图2所示空调室内机运行下吹模式时的示意图；图6是图2所示空调室内机运行双向送风模式时的示意图；图7是图2所示空调室内机运行最大送风模式时的示意图；图8是应用了本发明另一实施例的导风筒20的空调室内机的结构示意图。
如图2所示，当空调室内机处于关机状态或其他不需要送风的状态时，可使导风筒20转动至使导风段21朝外的角度，且使导风板50转动至关闭状态，以便利用导风段21和导风板50共同封闭出风口12。以避免灰尘等杂质通过出风口12进入壳体10内部。
如图4和图8所示，可使导风板50转动至关闭状态，使导风筒20转动至使导风段21的内壁211朝后上方的角度，以便将气流向前或上扬吹出，形成上吹模式。当空调室内机运行制冷模式时，优选采用上吹模式，实现天幕式柔风制冷。
如图5所示，可使导风板50转动至打开状态，使导风筒20转动至使导风段21的内壁211朝后的角度，以便将气流向下方引导，形成下吹模式。空调室内机运行制热模式时，优选采用下吹模式，使热风更好地抵达地面，实现地暖式柔风制热。
如图6所示，可使导风板50转动至打开状态，使导风筒20转动至使导风段21的内壁211朝上的角度，以使气流分成两路向外吹出，实现双向送风模式，形成环绕形气流。
如图7所示，可使导风板50转动至打开状态，使导风筒20转动至使导风段21的内壁211朝后下方的角度，以便尽量少地遮挡出风口12，从而导风筒20对气流的阻碍最小，使得气流最为顺畅地向外吹出，形成最大送风模式。
在一些实施例中，空调室内机设置有能感测人体位置的传感器，其与空调的控制器电连接，以便控制器根据人体与空调室内机的距离来自动选择送风模式。
具体地，当传感器检测到人员距离空调室内机较远时，控制器自动调整导风筒20和导风板50的角度，进入最大送风模式，此时整个风道全部打开，风阻小，风速高，送风距离远；
当传感器感知到人员由远及近的靠近空调室内机时，控制器自动调整导风筒20和导风板50的角度至上吹模式，以使气流向上倾斜一定角度后送出， 避免冷风直吹人体带来的不舒适感；
当传感器感知到人员处于空调室内机正前方时，自动调整导风筒20和导风板50的角度，进入双向送风模式，此时气流分别送上下两个方向环绕出风，不吹人体，同时增加空间空气流动效率，增加人员舒适性。
如图2所示，本发明实施例中，壁挂式空调室内机可为利用蒸气压缩制冷循环系统进行制冷/制热的分体壁挂式房间空调器的室内部分。壳体10的内部设有换热器30和风机40。换热器30、节流装置与设置于空调室外机内的压缩机、冷凝器以及其他的制冷元件通过管路相连接，构成一蒸气压缩制冷循环系统。在风机40的作用下，室内空气经壳体10顶部的进风口11进入壳体10的内部，与换热器30完成强制对流换热后，形成热交换风，然后再在风道的引导下吹向风道的出口，然后经出风口12吹向室内环境，完成对室内环境空气的调节。风机40优选为贯流风机，其设置在风道的进口处。换热器30优选为三段式换热器。
在本实施例的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
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。
