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。
现有的空调室内机多为单个贯流风扇配合单一常规出风口，存在以下问题：对于大客厅，送风量不足，送风角度小，送风距离单一，送风模式单一，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、送风调节模式更丰富的空调室内机。
本发明进一步的目的是要提高非换热气流与换热气流的混合效果。
本发明的进一步的目的是要提高每个风道的风量。
特别地，本发明提供了一种空调室内机，其包括：
机壳，其开设有一送风口，且其内形成有并排设置的两个风道，所述两个风道的出口连通所述送风口；和
中间送风部，在一缩进状态和伸出状态之间可往复运动地设置在所述两个风道之间，用于受控地向外输出气流；并配置成：
在所述缩进状态，所述中间送风部位于所述送风口内侧，以允许其输出气流和所述两个风道的出风气流均吹向所述送风口；且
在所述伸出状态，所述中间送风部将所述送风口分隔为两个区段，每个所述区段各对应一个所述风道的出口。
可选地，每个所述风道由间隔设置的第一风道壁和第二风道壁限定出；
两个所述第二风道壁相邻，且处于两个所述第一风道壁之间；且
每个所述第二风道壁沿气流方向依次包括转动连接的主体段和调节段，以在所述中间送风部处于不同状态时，使两个所述调节段转动至不同角度，以使两者末端贴靠于所述中间送风部表面。
可选地，所述中间送风部为中空结构，其外表面包括朝向所述送风口以 用作输出气流的出风面和从所述出风面的两侧朝背离所述送风口方向弯折延伸出的两个侧面；
在所述中间送风部处于所述缩进状态时，两个所述调节段的末端分别抵靠于所述出风面的横向两边；
在所述中间送风部处于所述伸出状态时，两个所述调节段的末端分别抵靠于两个所述侧面。
可选地，每个所述侧面与所述出风面的夹角为钝角。
可选地，在从所述风道的上游至下游的方向上，两个所述风道的间距先逐渐增大，后逐渐变小。
可选地，在从所述风道的上游至下游的方向上，两个所第二风道壁的距离先逐渐变大，后逐渐变小，两个所述第一风道壁均为弯曲状且两者的凹侧相向。
可选地，空调室内机还包括：两个风机，每个所述风机设置在一个所述风道内。
可选地，空调室内机还包括：两个导风装置，设置在所述送风口处用于引导风向，每个所述导风装置独立受控且对应一个所述风道的出口。
可选地，所述机壳为竖直延伸的柱状且所述送风口朝前敞开，所述两个风道沿所述机壳的横向并排设置；且所述中间送风部为竖条状。
可选地，所述中间送风部的输出气流为新风气流。
本发明的空调室内机中，并排的两个风道之间设置有一中间送风部，中间送风部输出的气流可为从室外引入的新风气流、经过净化或过滤的净化气流或者经加湿后的加湿气流、或者还可为室内常温空气。由于中间送风部可伸缩，使空调室内机具有多种送风模式。例如，可使中间送风部处于伸出状态，以将送风口分为两区段，使得两个风道与中间送风部的送风相互影响较弱，能够相对独立地进行送风。也可将中间送风部调节至缩进状态，这使得其输出气流和两个风道的出风气流均吹向所述送风口，在送风口处汇聚，两风道送风时在送风口形成压差，能够带动中间送风部内气流的流出，以使中间送风部无需常常开启风扇甚至省略风扇。而且，各股气流在送风口处提前进行混合，特别是当中间送风部吹出的为新风气流时，新风与换热气流提前混合会使室内清新速度更快。
进一步地，本发明的空调室内机中，使第二风道壁包括可转动的调节段， 以在中间送风部处于不同状态时，使两个调节段转动至不同角度，以使两者末端贴靠于中间送风部表面，避免风道流出的换热气流流至两个风道之间空间而导致浪费。

本发明提供了一种空调室内机。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、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7示意的是立式空调室内机的实施例。
图1是根据本发明一个实施例的空调室内机的分解示意图；图2是图1所示空调室内机在中间送风部70处于伸出状态时的示意图；图3是图2所示空调室内机切换为仅中间送风部70出风时的示意图；图4是图1所示空调室内机在中间送风部70处于缩进状态时的示意图。
如图1至图4所示，本发明实施例的空调室内机一般性地可包括机壳10和中间送风部70。
机壳10开设有一送风口12，机壳10内形成两个并排设置的多个风道20，两个风道20的出口连通送风口12，以经送风口12向室内环境送风。当然，机壳10也可以具有其他的送风口。本实施例所述的机壳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20的风道壁等机体部件。送风口12用于将机壳10内的调节气流吹向室内，以调节室内空气。
中间送风部70在一缩进状态和伸出状态之间可往复运动地设置在两个风道20之间，用于受控地向外输出气流。
在图1至图7所示的实施例中，风道20输出的调节气流为换热气流，也就是空调室内机在制冷模式下制取的冷风，或者在制热模式下制取的热风。空调室内机可为利用蒸气压缩制冷循环系统进行制冷/制热的空调的室内机，其内设置有换热器40。室内空气经进风口进入机壳10，与换热器40完成换热后形成换热气流，在风机80作用下进入风道20，然后经送风口12吹向室内环境。
中间送风部70输出的气流可为非换热气流，例如从室外引入的新风气流。具体地，中间送风部70为筒状结构，其引入室外新风气流，然后通过筒壁的孔口结构向外输出。当然，中间送风部70还可包括风扇以促使新风气流的流出。或者，中间送风部70输出的气流也可为经过机壳10内部净化部件净化、过滤的净化气流或者经加湿后的加湿气流、或者还可为室内常温空气。
中间送风部70配置成：在缩进状态，其处于送风口12内侧，以允许其输出气流和两个风道20的出风气流均吹向送风口12，如图4；在伸出状态，中间送风部70将送风口12分隔为两个区段，每个区段各对应一个风道20的出口，如图2。中间送风部70的这种可伸缩结构使得空调室内机具有多种送风模式。
例如图2所示，将中间送风部70调节至伸出状态，使其将送风口12分为两区段，每个风道20通过相应的区段向外送风，使得两个风道20与中间送风部70的送风相互影响较弱，能够相对独立地进行送风。如图3所示，也可仅使中间送风部70送风，使两个风道20不送风。当室内环境没有制冷/制热需求时，但有新风或净化需求时，可仅开启中间送风部70。当然，这需要中间送风部70独立匹配风扇，以促使其内气流的流出。
例如图4所示，也可将中间送风部70调节至缩进状态，这使得其输出气流和两个风道20的出风气流均吹向所述送风口12，在送风口12处汇聚，两风道20送风时在送风口12形成压差，能够带动中间送风部70内气流的流出，以使中间送风部70无需常常开启风扇甚至省略风扇。而且，各股气流在送风口12处提前进行混合，使得非换热气流与换热气流的混合效果更好。特别是当中间送风部70吹出的为新风气流时，新风与换热气流提前混合会使室内清新速度更快。
在一些实施例中，如图1至图4所示，空调室内机还包括两个风机80， 每个风机80设置在一个风道20内。风机80的作用是促使机壳10内的气流流入风道20，然后经送风口12吹向室内环境。可以理解的是，两个风机80的运行也是独立受控的，可以选择仅开启一个风机80，或选择同时开启两个风机80。每个风机80的转速也是独立受控的。每个风机80的额定功率可以相同，也可以不同。在一些替代性实施例中，也可使两个风道20共用一个风机。
图5是图1所示空调室内机在中间送风部70处于伸出状态但不出风时的示意图；图6是图5所示空调室内机在左侧导风装置61朝左导风，右侧导风装置62朝右导风时的示意图；图7是图1所示空调室内机在中间送风部70处于缩进状态但不出风时的示意图。
本发明一些实施例中，如图5至图7所示，当室内环境仅有制冷/制热的需求时，也可使中间送风部70能停止出风，使空调室内机仍利用风道20正常吹出换热气流。
在一些实施例中，如图1至图4所示，每个风道20由间隔设置的第一风道壁21(即蜗壳)和第二风道壁22(即蜗舌)限定出。第二风道壁22为两个。两个第二风道壁22相邻，且处于两个第一风道壁21之间。每个第二风道壁22沿气流方向依次包括转动连接的主体段221和调节段222(两个转动轴线分别为x1、x2)，以在中间送风部70处于不同状态时，使两个调节段222转动至不同角度，以使两者末端(C、D)贴靠于中间送风部70的表面。本实施例通过使两个第二风道壁22的调节段222能转动，使两调节段222的末端始终与中间送风部70相贴靠，形成密封，以避免风道20的气流流入两个第二风道壁22之间空间，造成浪费。
进一步地，请参考图2和图4，中间送风部70为中空结构，其外表面包括朝向送风口12以用作输出气流的出风面701和从出风面701的两侧朝背离送风口12方向弯折延伸出的两个侧面702。出风面701上可设置出风口71。在中间送风部70处于缩进状态时，两个调节段222的末端(C、D)分别抵靠于出风面701的横向两边(a、b)，这使得出风面701构成两个调节段222末端的连接面，避免两者之间产生泄漏。在中间送风部70处于伸出状态时，两个调节段222的末端分别抵靠于两个侧面702，如图2。具体可使两个调节段222的末端分别抵靠于两个侧面702的末端(c、d)。如此使得两个侧面702充当两个调节段222的延长段，使得两个侧面702也构成两 个风道20的内壁，用于引导气流，设计非常巧妙。每个侧面702与出风面701的夹角为钝角，如此可使两个侧面702从内向外间距逐渐变大，使得两个风道20的出口更大。此外，中间送风部70还包括背面703(cd段)，其横向两边连接在两个侧面702的后边。
在一些实施例中，如图1至图4所示，在从风道20的上游至下游的方向上，两个风道20的距离先逐渐变大，后逐渐变小，以通往同一送风口12。如此一来，一方面能够更加高效地利用机壳10的宽度，形成风道20需要的高效率蜗形。另一方面也使得每个风道20的出风气流朝另一风道20偏斜(左侧风道20出风气流朝右偏斜，右侧风道20的出风气流朝左偏斜)，使得两股气流在送风口12处能够相互冲击，使两个风道20的出风气流的相互促进作用更加强大。
具体地，在从风道20的上游至下游的方向上，两个第二风道壁22的距离先逐渐变大，后逐渐变小，两个第一风道壁21均为弯曲状且两者的凹侧相向。这样即构成了高效率的蜗形，且在从风道20上游至下游的方向上，使两个风道20的间距先逐渐增大，后逐渐变小。
此外，空调室内机还包括两个导风装置61、62。两个导风装置61、62设置在送风口12处用于引导风向，每个导风装置独立受控且对应一个风道20的出口。也就是说，每个导风装置61、62的导风方向是互不影响的，能够独立地对其所覆盖区域的气流进行方向引导。由于设置了多个独立受控的导风装置61、62，如此，既能利用多个导风装置61、62朝多个方向导风，扩大整体送风范围，又能利用多个导风装置61、62朝同一方向导风，使得多股气流相互汇集促进，使风力更加强劲，对室内某区域针对性地吹风。
前文已述，图1至图7示意了立式空调室内机的实施例，图1至图7示意的以水平面剖切空调室内机得到的剖视图。
对于立式空调室内机的实施例，机壳10为竖直延伸的柱状，且优选使送风口12朝前敞开，两个风道20沿机壳10的横向并排设置，且中间送风部70为竖条状。可使风道20和送风口12均为沿上下方向延伸的长条状。风机80优选为轴线竖直延伸的贯流风机。在一些替代性实施例中，也可使送风口12为其它形状，相应地，风机80也可为轴流风机、离心风机等其他样式的风机。本发明对风道20、送风口形状以及风机样式不作特别限定。
可使整个送风口12的风向是相同的，以便能够使两个风道20吹出的两 股气流(或者还包括中间送风部70的出风气流)汇集后相互促进，使风力更加强劲，能够对室内某区域针对性地吹风，如图2、图4、图5和图7，使两个导风装置61、62均朝前导风。当然也可以均朝左或均朝右导风。
或者，还可使两个导风装置61、62的导风方向不同，扩大整体送风范围。例如可如图6所示，使左侧的导风装置61朝左导风，使右侧的导风装置62朝右导风。此外，还可使导风装置61、62能够遮蔽风道20的出口，例如图3，以便选择封闭一个或两个风道20，同时关闭相应的风机80。
当然，前文仅仅以图1至图7为例，对本发明的空调室内机部分优选的送风方式进行举例介绍，但并未穷尽，本发明的空调室内机还有更多的送风方式，在此不再一一列举。
在一些实施例中，如图1至图7所示，每个导风装置61、62包括多个摆叶，每个导风装置61、62的各摆叶配置成同步转动地调节送风口12的横向出风方向。具体地，每个摆叶沿竖直方向延伸的条形板状，每个摆叶的转动轴线平行于竖直方向，多个摆叶之间可通过联动机构实现联动，在电机的驱动下实现同步转动。这种多个摆叶的联动机构在空调领域使用非常广泛，在此不详细介绍。当多个摆叶转动至共面状态时，其能够遮挡送风口12。在一些替代性实施例中，也可使导风装置61、62为单个竖直延伸的可转动的条状导风板，具体不再介绍。
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。
