Description

空调室内机 技术领域
本发明涉及空调技术领域，特别涉及一种空调室内机。
背景技术
目前，传统的壁挂式空调室内机多为上进风、下出风的气流循环方式，且用于驱动气流循环的装置多为贯流风扇。气流沿垂直于贯流风扇的轴向方向进入贯流风扇的内部，并两次穿过贯流风扇的叶轮，在叶轮内部，气流被强制弯折，使得气流的压力损失较大，风量较低，整机运行时的噪音较大。
为了避免采用贯流风扇驱动气流循环带来的一系列问题，现有技术中的一些壁挂式空调室内机将贯流风扇替换成离心风扇。虽然这种壁挂式空调室内机能够在一定程度上解决上述风量较低、气流压损较大的问题，但效果却不是特别明显，并且丝毫不能解决噪音较大的问题。像噪音大、风量小这种用户能够通过直观感受体验到的缺陷严重影响了壁挂式空调室内机的整体使用性能，并且大大限制了壁挂式空调室内机的使用范围。
发明内容
本发明的目的旨在克服现有技术中的至少一个缺陷，提供一种风量较大且噪音较小的空调室内机。
本发明的进一步的目的是要优化空调室内机的外形，使其机身更薄，外观更加美观。
特别地，本发明提供了一种空调室内机，其包括：
壳体，其为中心轴线沿前后方向延伸的圆柱状，其后端为进风端，前端为出风端；
换热装置，其设置在壳体内，用于与从进风端进入壳体的空气进行热交换，形成热交换风；和
送风组件，其包括多个轴流风扇，多个轴流风扇前后串联设置在壳体内，且其旋转轴线均沿前后方向延伸，用于促使热交换风从出风端吹向室内。
可选地，壳体包括中心轴线沿前后方向延伸的圆柱状的筒体、安装在筒体后端的进风格栅以及安装在筒体前端且中部开设有圆形开口的前端盖；且 送风组件还包括风道部件，其包括嵌设在圆形开口内的外圈、位于外圈内侧的内圈以及两端分别连接于外圈前部和内圈前部的多个格栅条，外圈与内圈之间限定出环形风道，以允许热交换风经环形风道吹向室内；且多个轴流风扇采用同一电机驱动，电机固定于内圈内。
可选地，每个格栅条与内圈的连接点位于该格栅条与外圈的连接点的后方。
可选地，外圈的后端径向向外延伸出翻边，翻边抵靠于筒体的内周面。
可选地，内圈具有从前向后的凹腔，电机设置在凹腔内，凹腔前侧安装有盖板，以封盖凹腔。
可选地，换热装置为平板状翅片换热器。
可选地，换热装置设置在每个轴流风扇的后方；或换热装置设置在相邻两个轴流风扇之间。
可选地，多个轴流风扇的数量为两个。
可选地，每个轴流风扇均为子午加速轴流风扇。
可选地，空调室内机为壁挂式空调室内机。
本发明的空调室内机的壳体外形为圆形，外观非常时尚美观。并且，该空调室内机采用轴流风扇进行送风，气流由后向前地贯穿壳体，缩短了气流流动距离，减小了风压损失和能量损失，提高了空调室内机的运行效率。此外，轴流风扇的送风向外扩散比较快，避免了风向前直吹人体给人带来不舒适感。
并且，本发明将多个轴流风扇串联设置，相比于单轴流风扇的方案，风压更大，风量更大，送风距离更远。相比于单轴流风扇的方案，本发明的空调室内机可采用两个直径更小的轴流风扇，使空调室外机的壳体直径更小，满足用户的使用需求。
进一步地，本发明的空调室内机中，风道部件上集成了环形风道、格栅条、轴流风扇和电机，使结构更加紧凑，安装更加方便。
进一步地，本发明的空调室内机采用子午加速轴流风扇，与普通的圆柱面流动的轴流风扇相比，子午加速风扇轮毂从进风侧到出风侧为弧形渐扩的形状，使得空气流通面积逐渐变小，速度不断增大，从而提高了进出口侧压差。因此，子午加速轴流风扇具有高压、高效、流量大和噪音低等优点，更适合应用于本发明的空调室内机。
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。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据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所示空调室内机的剖视图；
图3是图1所示空调室内机的分解示意图；
图4是子午加速轴流风扇的结构示意图。
具体实施方式
下面参照图1至图4来描述本发明实施例的空调室内机，本发明实施例的描述中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件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。
图1是根据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所示空调室内机的剖视图；图3是图1所示空调室内机的分解示意图；图4是子午加速轴流风扇的结构示意图。如图1至图4所示，本发明实施例的空调室内机包括壳体100、换热装置200以及送风组件。图1和图2中标示了前后方向，图2标示了风向。
壳体100为中心轴线沿前后方向延伸的圆柱状，其后端为进风端，前端为出风端，以允许室内空气从壳体100的后端进入壳体100，换热成为热交换风后从壳体100的前端吹出。具体地，如图2，壳体100可包括中心轴线沿前后方向延伸的圆柱状的筒体110、安装在筒体110后端的进风格栅120以及安装在筒体110前端且中部开设有圆形开口132的前端盖130。本发明实施例通过使壳体100的外形为圆柱状，使其外观非常时尚美观。
在一些实施例中，空调室内机可为壁挂式空调的室内机。
换热装置200设置在壳体100内，用于与从壳体100的进风端进入壳体 100的空气进行热交换，形成热交换风。具体为用于与经进风格栅120进入壳体100的室内空气进行热交换，形成热交换风。空调室内机可与空调室外机一同构成蒸气压缩制冷循环系统，实现对室内环境的制冷/制热。换热装置200可为翅片换热器，可为U型或平板状，优选为板状翅片换热器。
送风组件包括多个轴流风扇320。多个轴流风扇320前后串联设置在壳体100内，且其旋转轴线均沿前后方向延伸，用于促使热交换风从壳体100的出风端吹向室内。
空调运行时，轴流风扇320向前吸换热装置200处的热交换风，因气流由后向前贯穿空调室内机，缩短了气流流动的距离，减小了风压损失和能量损失，提高了空调室内机的整机的运行效率。串联设置多个轴流风扇相比于单轴流风扇的方案，风压更大，风量更大，送风距离更远。相比于单轴流风扇的方案，本发明的空调室内机可采用两个直径更小的轴流风扇，使空调室外机的壳体直径更小，满足用户的使用需求。轴流风扇的数量优选为两个，既能增大风量，又不会使空调室内机因设置过多风扇而过厚。
在一些实施例中，如图2和图3所示，送风组件还包括风道部件310。风道部件310包括嵌设在圆形开口132内的外圈311、位于外圈311内侧的内圈312以及两端分别连接于外圈311前部和内圈312前部的多个格栅条313。外圈311与内圈312之间限定处一个环形风道301，以用于换热装置200处的热交换风向外引导。多个格栅条313形成出风格栅，用于向外吹风，并可在一定程度上对出风的方向进行导向。多个轴流风扇320位于环形风道301的后侧进口处，且采用同一个电机321驱动，电机321固定于内圈312，其轴向后延伸以连接每个轴流风扇320，使多个轴流风扇320同速转动。轴流风扇320开启后，可促使热交换风经环形风道301向前吹出，吹向室内。换热装置200可设置在轴流风扇320的后方。在一些替代性的实施例中，也可将换热装置200设置在相邻两个轴流风扇之间。
在一些实施例中，如图1和图3所示，内圈312具有从前向后的凹腔316，电机321设置在凹腔316内，凹腔316前侧安装有盖板330，以封盖凹腔316。
本发明实施例的装配过程十分方便。参考图3，可先将进风格栅120安装于筒体110，将轴流风扇320与电机321装配好后，安装于风道部件310，再将风道从前向后嵌入筒体110，之后安装前端盖130，最后安装盖板330。
在一些实施例中，优选使轴流风扇320、筒体110以及环形风道301同 轴设置，以利于热交换风向前吹送，提升送风量和送风效率。
在一些实施例中，如图2和图3所示，外圈311的后端径向向外延伸出翻边314，翻边314抵靠于筒体110的内周面。翻边314作为外圈311的延伸，能够将热交换风全部引导至环形风道301内，而不会进入区域302造成浪费。而且，翻边314抵靠在筒体110的内周面还能够使外圈311与筒体110之间的连接更加稳固。
在一些实施例中，如图1和图3所示，每个格栅条313与内圈312的连接点位于该格栅条313与所述外圈311的连接点的后方，或者说，每个格栅条313从内圈312向外圈311延伸过程中，逐渐轴向向前偏斜。如此扩大了出风口的面积，利于出风的扩散，避免风大风量地直吹人体给人体带来不适。
在一些实施例中，可采用子午加速轴流风扇代替上述实施例的轴流风扇320。请参考图4，子午加速轴流风扇的叶轮包括轮毂322和多个扇叶323。轮毂322为锥形，即从进口处到出口处(从后向前)逐渐加大，使叶轮流道的截面积沿流动方向逐渐减少，气流经过叶轮子午面的分速度(子午速度)得到提高，提高了进出口侧压差。因此，子午加速轴流风扇具有高压、高效、流量大和噪音低等优点。
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。
