Description

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。
现有空调室内机通常在机壳前侧设置一个竖条状或横条状的出风口，通过导风装置实现上下左右摆风，扩大送风角度。
在此基础上，一些现有技术对出风结构进行了很多改进，但由于受到出风口本身朝向的约束，空调的送风方向、送风范围和送风距离仍然受到极大限制，特别是制冷时冷风吹人的问题难以解决，影响用户体验。
发明内容
本发明的目的是要克服上述问题或者至少部分地解决上述问题，提供一种送风体验更好的空调室内机。
本发明的目的是要丰富空调室内机的送风调节模式。
本发明的目的是要增大空调室内机的送风角度和送风距离。
特别地，本发明提供了一种空调室内机，其包括：
机壳，其限定有至少一个主风道和与之相邻的聚合风道，所述主风道具有主送风口，所述聚合风道具有聚合送风口，均用于向室内环境送风；所述主风道开设有一旁通开口与所述聚合风道连通，以将所述主风道的调节气流引入所述聚合风道；所述聚合风道至少邻近所述聚合送风口的区段为使出风截面沿气流方向逐渐变小的渐缩状；和
导流件，设置在所述聚合风道内，用于将气流导向所述聚合风道的内壁，使气流经所述导流件与所述聚合风道内壁之间的间隙流出，并且在所述聚合风道内壁的引导下在所述聚合送风口外侧聚合。
可选地，所述主风道的数量为两个，所述聚合风道设置在两个所述主风道之间。
可选地，所述机壳为竖直延伸的柱状；
两个所述主风道沿所述机壳的横向排列；且
两个所述主送风口和所述聚合送风口均朝前敞开。
可选地，每个所述主风道的进口处设置有一贯流风机；且
所述空调室内机还包括换热器，其位于两个所述贯流风机后方，所述换热器的横向两侧向前弯折，以使其两个边缘分别抵靠于两个所述主风道的内壁。
可选地，所述导流件配置成可沿接近或远离所述聚合送风口的方向平移，以便调节其与所述聚合风道内壁的间距。
可选地，所述导流件为长度方向垂直于所述聚合送风口的宽度方向的柱状；且所述导流件的横截面整体为椭圆形或橄榄形，其两个尖端分别朝向所述聚合风道的两侧内壁，一个外凸曲面朝向所述聚合送风口。
可选地，所述导流件在移动至使其两个尖端分别抵靠于所述聚合风道的两侧内壁时，使所述导流件将所述聚合风道封闭。
可选地，每个所述旁通开口处设置有一风门，所述风门配置成受控地开闭所述旁通开口。
可选地，所述风门可枢转地安装于所述旁通开口的一边，以转动地开闭所述旁通开口。
可选地，所述风门配置成在打开所述旁通开口后，可转动至遮挡所述主风道的位置。
本发明的空调室内机中，主风道旁边设置有聚合风道，主风道通过旁通开口连通聚合风道，以将主风道内的调节气流(冷风或热风)引入聚合风道，使气流在导流件的作用下分流至聚合风道的渐缩状内壁，使气流在渐缩状内壁的引导下逐渐靠近，在聚合送风口外实现聚合，实现聚合送风效果，使风力更强、送风距离更远。本发明的空调室内机既可通过主送风口实现常规送风，又能通过聚合送风口实现聚合送风，送风方式更加多样化，拥有多种送风模式，以充分满足用户不同情况的不同需求，使得用户的风感体验更好。
进一步地，本发明的空调室内机中，使导流件能沿接近或远离聚合送风口的方向平移，以使导流件与聚合风道内壁的间隙可调，从而能够调节聚合送风的风量。并且，本发明还能进一步利用导流件关闭聚合风道，使聚合送风量调节为零。
进一步地，本发明的空调室内机中，每个旁通开口处设置有一风门，以便开闭旁通开口，以开启或停止聚合送风。此外，还可进一步使风门配置成 在打开旁通开口后，可转动至遮挡主风道的位置，如此，空调能够具有纯聚合送风模式，送风模式更加多样化。

图1是本发明一个实施例的空调室内机的结构示意图；图2是图1所示空调室内机在导流件50前移一定距离后的示意图；图3是图2所示空调室内机在导流件50进一步前移以关闭聚合风道30时的示意图。需要注意的是，各图仅仅示意了本发明的一些可选的送风模式，还有一些送风模式并未明确列出介绍。
如图1至图3所示，本发明实施例的空调室内机一般性地可包括机壳10和导流件50。
其中，本发明实施例所述的机壳10包括用于构成室内机基本框架的骨架和用于限定出风道的蜗壳、蜗舌等机体部件。机壳10限定有至少一个主风道20和与之相邻的聚合风道30(聚合风道30的两侧内壁分别为B1C和B2D)。主风道20具有主送风口11，聚合风道30具有聚合送风口12(CD)，主送风口11和聚合送风口12均用于向室内环境送风，也就是将空调室内机制取的调节气流经主送风口11和/或聚合送风口12吹向室内环境，完成对室内空气的调节过程。调节气流可为空调室内机在制冷模式下制取的冷风，在制热模式下制取的热风。主风道20开设有一旁通开口21(两个旁通开口21分别为A1B1、A2B2)与聚合风道30连通，以将主风道20的调节气流引入聚合风道30。也就是说，聚合风道30的气流来源于主风道20。聚合风道30至少邻近聚合送风口12的区段为使出风截面沿气流方向逐渐变小的渐缩状， 例如图1所示，使聚合送风口12的全部区段为渐缩状。
导流件50设置在聚合风道30内，用于将气流导向聚合风道30的内壁，使气流经导流件50与聚合风道30内壁之间的间隙流出，并且在聚合风道30内壁的引导下在聚合送风口12的外侧聚合。
由于增加了导流件50，调节气流向前流动过程中，导流件50后表面引导下分别流向导流件50的两侧，分别流向导流件50与聚合风道30内壁形成的间隙，出风速度更快。且由于聚合送风口12的邻近聚合送风口12的区段为渐缩状，使得各股气流在向外流动过程中逐渐向气流中心方向聚合，汇聚成一股，使得风力非常强劲，送风距离更远，满足了空调室内机对远距离送风和强劲送风的需求
本发明实施例的空调室内机既可通过主送风口11实现常规送风，又能通过聚合送风口12实现聚合送风，送风方式更加多样化，拥有多种送风模式，以充分满足用户不同情况的不同需求，使得用户的风感体验更好。
在图1至图5所示实施例中，机壳10呈竖直柱状延伸，也就是使空调室内机为立式空调室内机。主风道20、主送风口11、聚合风道30和聚合送风口12均为竖条状。导流件50为竖直延伸的柱状。当然，在附图未示意的实施例中，也可使空调室内机为壁挂式，使机壳为长度方向水平延伸的长条状，使主风道、主送风口、聚合风道和聚合送风口相应均为水平横向延伸的长条状，具体不再赘述。
在一些实施例中，如图1至图3所示，导流件50配置成可沿接近或远离聚合送风口12的方向平移，以便调节其与聚合风道30内壁的间距。例如，相比于图1，图2的导流件50更加接近聚合送风口12，使其与聚合风道30内壁的间距更小。本实施例通过平移导流件50，调节其与聚合风道30内壁的间距，从而能够调节聚合送风的风量。进一步地，还可使导流件50能关闭聚合风道30。例如图3所示，可进一步平移导流件50，使其与聚合风道30的内壁接触，从而关闭聚合风道30，也就是将聚合送风量调节为零。可利用电机和齿轮齿条机构驱动导流件50平移，具体结构不再赘述。
如此，使得本发明实施例的空调室内机的送风调节模式非常丰富，便于空调室内机根据运行工况的不同和用户需求的不同来调节不同的送风模式。例如，如图1所示，可使聚合送风口12和主送风口11均打开，以同时进行常规送风和聚合送风。或者，如图2所示，平移导流件50，调小聚合送风量。 或者如图3所示，关闭聚合送风口12，完全由主送风口11送风。
主送风口11处可设置有导风装置60，以对主送风口11的送风方向进行引导。例如图1至图3所示，导风装置60可为导叶。
在一些实施例中，可使导流件50为长度方向垂直于聚合送风口12的宽度方向的柱状，即长度方向垂直于各图的纸面方向。导流件50的横截面整体为椭圆形或橄榄形。可知，椭圆或橄榄形具有两个尖端(a、b)以及两个外凸曲面51、52。两个尖端(a、b)分别朝向聚合风道30的两侧内壁(B1C、B2C)，一个外凸曲面51朝向聚合送风口12。当导流件50在移动至使其两个尖端(a、b)分别抵靠于聚合风道30的两侧内壁时，使导流件50将聚合风道30封闭，如图3。由于外凸曲面52朝向聚合风道30的内部，能将气流顺畅地分散至导流件50的横向两个尖端处，也就是导流件50与聚合风道30形成的两个间隙处。使另一外凸曲面51朝向室外环境，气流在康达效应的作用下，能引导聚合风道30两侧内壁的气流沿该外凸曲面51的表面向其中心方向流动，有助于两股气流的聚合。
图4是本发明另一实施例的空调室内机的示意图；图5是图4所示空调室内机在风门70打开后的示意图。
如图4和图5所示，在一些实施例中，每个旁通开口21处设置有一风门70，风门70配置成受控地开闭旁通开口21。当风门70打开旁通开口21时，允许主风道20内的气流进入聚合风道30，进行聚合送风。反之，当风门70关闭旁通开口21时，主风道20内的气流无法进入聚合风道30，不进行聚合送风。
在一种可选方案中，如图4和图5所示，风门70可枢转地安装于旁通开口21的一边，以转动地开闭旁通开口21。可利用电机驱动风门70转动。进一步地，还可使风门70配置成在打开旁通开口21后，可转动至遮挡主风道20的位置。具体地，使风门70的枢转端连接于旁通开口21的靠近下游的一边。如此，风门70打开旁通开口21后，即关闭了主风道20，使得气流全部进入聚合风道30，使聚合出风风量更大。
在一些替代性实施例中，也可使风门70可平移地地开闭旁通开口21，具体结构不再赘述。
在一些实施例中，主风道20的数量为两个，聚合风道30设置在两个主风道20之间。例如图1至图5所示，对于立式空调室内机，机壳10为竖直 延伸的柱状，优选使两个主风道20沿机壳10的横向排列(图中已经标示出横向)，两个主送风口11和聚合送风口12均朝前敞开。本实施例设置左右两个主风道20，每个主风道20的送风模式都可独立受控，这使得送风角度范围更大，送风调节模式更多。
如图1所示，可使每个主风道20的进口处设置有一贯流风机80，空调室内机还包括换热器40，换热器40位于两个贯流风机80后方，换热器40的横向两侧向前弯折，以使其两个边缘分别抵靠于两个主风道20的内壁。机壳10的进风口(未图示)开设于机壳10的后壁，在贯流风机80的作用下，室内气流从进风口进入机壳10，与换热器40完成换热，然后进入两个主风道20。由于换热器40已经完全封堵两个主风道20的进口，使得换热气流完全进入两个主风道20，避免风量浪费。
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。
