Description

立式空调室内机 技术领域
本发明涉及空气调节技术领域，特别涉及一种立式空调室内机。
背景技术
目前，传统的立式空调室内机多采用离心风扇作为动力源来驱动空气流动。离心风扇和换热器沿上下方向排布在室内机的机壳内，进风口设置于机壳的下部，并与离心风扇相对，出风口设置于机壳的前侧上部，并与换热装置相对。空气经下部的进风口进入机壳内，并依次流经离心风扇的风道和换热器后从上部的出风口处送出。由此可见，气流由进风口至出风口流经的距离较长，风压损失较为严重，能量消耗较大，风扇的输出能力减弱，使得整机的运行效率大幅度地降低。
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，提供一种风扇风压损失较小、运行更加节能的立式空调室内机。
本发明的进一步的目的是要方便立式空调室内机各个组件的拆装维修。
特别地，本发明提供了一种立式空调室内机，其包括机壳，设置在机壳内的换热器以及在机壳内上下排列、轴线竖向延伸且共线地设置的第一贯流风扇和第二贯流风扇，机壳包括：
骨架，用于安装换热器、第一贯流风扇和第二贯流风扇；
底板，设置在骨架下方，用于支撑立式空调室内机；
前立柱和后立柱，分别从底板的前后两边向上延伸至骨架的底端，以支撑骨架；
左立柱和右立柱，分别从底板的左右两边向上延伸至骨架的顶端，以固定骨架；
外壳，包围在骨架的外侧，且下端延伸至底板的边缘，外壳的前侧设置有多个出风口，后侧设置有进风口。
可选地，外壳上共设置有三个形状相同的出风口；且第一贯流风扇对应其中两个出风口，第二贯流风扇对应另外一个出风口。
可选地，外壳上共设置有两个出风口，第一贯流风扇对应的出风口的过流面积为第二贯流风扇对应的出风口的过流面积的两倍。
可选地，第一贯流风扇和第二贯流风扇的风轮直径相同；且第一贯流风扇的长度为第二贯流风扇的两倍。
可选地，第一贯流风扇位于第二贯流风扇的上方。
可选地，换热器为竖向延伸且开口朝前的“U”型换热器，第一贯流风扇和第二贯流风扇位于换热器的前方内侧。
可选地，骨架上设置有竖立在第一贯流风扇和第二贯流风扇的周向外侧的风道组件，风道组件包括：竖向间隔设置的两个端板部，第一贯流风扇的驱动电机和第二贯流风扇的驱动电机分别安装于两个端板部；蜗壳，竖立设置且连接在两个端板部之间；蜗舌， 竖立设置且连接在两个端板部之间，并与蜗壳共同将空气从换热器处向前引流至多个出风口处。
可选地，立式空调室内机还包括：风道分隔件，连接在蜗壳和蜗舌之间，且位于第一贯流风扇与第二贯流风扇之间，以将风道组件限定的空间分隔为上下两部分，分别容纳第一贯流风扇和第二贯流风扇；且风道分隔件上安装有分别与第一贯流风扇的转轴和第二贯流风扇的转轴匹配的两个轴承。
可选地，多个出风口均为圆形；立式空调室内机还包括：多个竖摆叶组，位于外壳内侧，与多个出风口一一匹配，每个竖摆叶组包括竖向延伸且分别可枢转地安装于骨架的多个竖摆叶，以枢转地实现左右摆风；和多个横摆叶组，在竖摆叶组后方与多个出风口一一匹配，每个横摆叶组包括水平延伸且分别可枢转地安装于骨架的多个横摆叶，以枢转地实现上下摆风。
可选地，立式空调室内机还包括人体检测装置，配置成检测室内人体信息，人体信息包括人数、人体温度、人体位置；以及主控板，配置成根据人体信息，控制第一贯流风扇和第二贯流风扇同时或择一开启，并控制第一贯流风扇和第二贯流风扇的风速或出风口的送风方向。
本发明的立式空调室内机利用贯流风扇送风，进风口设置在贯流风扇后方，出风口设置在贯流风扇前方，如此可极大缩短整个送风过程空气的流程，减小了风压损失，提升了空调的整机能效。另外，本发明利用骨架150安装换热器和两个贯流风扇，并且利用两个较短的前立柱和后立柱以及两个较长的左立柱和右立柱来支撑骨架，相比于传统的立式空调室内机的立柱较少，拆卸维修比较方便。
进一步地，本发明通过设置多个出风口和第一贯流风扇和第二贯流风扇，并使第一贯流风扇对应的全部出风口的总过流面积大于第二贯流风扇对应的全部出风口的总过流面积，能够根据实际制冷/制热量需要，仅开启一个贯流风扇或者开启两个贯流风扇，不仅更加节能，还丰富了送风模式，提升了用户体验。
进一步地，本发明的立式空调室内机设置了一个风道组件和一个风道分隔件，风道分隔件将风道组件的空间分隔开分别容纳第一贯流风扇和第二贯流风扇，使两个贯流风扇的出风不会相互干扰，提升了送风效率。另外，相比于直接设置两个风道组件的方案，其结构更加简单，而且两个贯流风扇之间的衔接部位(该部位因无风扇，与之相对位的换热器部分的空气流动较差)更短，对换热器的换热更加有利。另外，通过在风道分隔件上设置轴承，使其结构更加巧妙。
进一步地，本发明的立式空调室内机，使出风口为圆形，更加美观。同时，将摆叶设置在前面板内侧的框架而非前面板上，可方便摆叶的设计、安装以及摆动。因为如果在圆形的出风口处设置摆叶，多个摆叶的长短不一，其在出风口处摆动时，两端也容易受到出风口弧形边缘的限制。
进一步地，本发明的立式空调室内机中，根据人体检测装置检测的人体信息来控制第一贯流风扇和第二贯流风扇的运行，使其控制更加合理、整机运行更加节能，人体感受更加舒适。
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。

具体实施方式
图1是根据本发明一个实施例的立式空调室内机的示意性前视图；图2是图1所示立式空调室内机的示意性爆炸图；图3是图2所示空调室内机骨架150结构的示意图；图4是图3的示意性爆炸图；图5是骨架150内部的风道组件、风机以及换热器的示意图。如图1至图5所示，本发明的立式空调室内机一般性地可包括机壳100、设置在机壳100内部的换热器200、两个贯流风扇即第一贯流风扇310和第二贯流风扇320，两个贯流风扇在机壳100内上下排列、轴线竖向延伸且共线地设置。
机壳100内部限定有容纳空间，以容纳贯流风扇和换热器200，其包括骨架150、底板160左立柱171和右立柱172、前立柱181和后立柱182以及外壳。骨架150用于安装换热器、第一贯流风扇和第二贯流风扇。底板160设置在骨架150下方，用于与地面接触，支撑立式空调室内机。
前立柱181和后立柱182分别从底板160的左右两边向上延伸至骨架150的底端，连接骨架150的底盘190，以支撑骨架150。使其延伸至骨架150底端是为了避免其阻挡立式空调室内机的进风和出风。左立柱171和右立柱172分别从底板160的前后两边向上延伸至骨架150的顶端，以固定骨架150。电器盒173连接在左立柱171和右立柱172之间，可起到进一步固位的作用。外壳包围在骨架150的外侧，且下端延伸至底板160的边缘，以构成立式空调室内机的外观。外壳的前侧设置有多个出风口112，后侧设置有进风口122。具体如图2所示，外壳包括前面板110、后面板120、左侧面板130以及右 侧面板140。前面板110上开设有竖向排列的多个出风口112，后面板120上设置有进风口122，进风口122可为设置在后面板120上的格栅结构。
换热器200与压缩机、冷凝器、节流装置、连接管路以及其他配件构成蒸汽压缩制冷循环系统，实现空调的制冷/制热，具体原理和结构在此不再赘述。
第一贯流风扇310和第二贯流风扇320各自对应一部分出风口，配置成促使空气经进风口进入机壳100，与换热器200换热后从对应的出风口吹出，实现室内空气与换热器200的强制对流换热，提升换热器200的换热效率。并且，优选使第一贯流风扇310的额定风量大于第二贯流风扇320的额定风量，使第一贯流风扇310对应的全部出风口的总过流面积大于第二贯流风扇320对应的全部出风口的总过流面积。
本发明实施例中，仅通过控制两个贯流风扇的开闭即可实现三个风量档的送风模式的切换，风量从小到依次为：仅开启第二贯流风扇320的模式、仅开启第一贯流风扇310的模式以及同时开启第一贯流风扇310和第二贯流风扇320的模式。并且，在这三种风量档送风模式下，再通过改变贯流风扇的风速，能够获取更加多样的送风模式，以满足用户的不同的需求，提升用户体验。
本发明利用骨架150安装换热器和两个贯流风扇，并且利用两个较短的前立柱181和后立柱182以及两个较长的左立柱171和右立柱172来支撑骨架150，相比于传统的立式空调室内机的立柱较少，拆卸维修比较方便。
此外，本发明实施例通过设置竖向排列的多个出风口112，能够在竖向方向上基本覆盖人体的活动空间，相比于现有技术的空调仅在前侧顶部设置一个出风口的方案，本发明实施例的送风范围更大(至少在上下方向上如此)。特别是在制热模式下，因热风具有上升趋势，如仅设置一个位置较高的出风口将不便于向下送热风，使室内底层空间的制热效果较差。而本发明实施例可利用最下方的出风口对底层空间输送热风，满足底层空间的制热需求。
在一些实施例中，使第一贯流风扇310位于第二贯流风扇320的上方。因第一贯流风扇310的额定风量更大，在立式空调室内机开启时，制冷量/制热量需求大，第一贯流风扇310被开启的可能极大，使其位于上侧，也就是使其处于稍稍低于人体身高的高度，便于向急需制冷/制热的人体周围空间送风。而第二贯流风扇320位于下侧，其对应下侧的出风口112，且风量较小，主要起到辅助第一贯流风扇310的作用。
在一些实施例中，如图1和图2所示，前面板110上共设置有三个形状相同的出风口112，且优选为圆形，以使立式空调室内机的外观更加美观。同时，使第一贯流风扇310对应其中两个出风口112，第二贯流风扇320对应另外一个出风口112。另外，如前所述，如使第一贯流风扇310位于第二贯流风扇320的上方，需使第一贯流风扇310对应上侧的两个出风口112，使第二贯流风扇320对应最下侧的出风口112。
本发明实施例可以通过竖摆叶和横摆叶来调节两个贯流风扇所对应的出风口112的出风方向，以扩大送风范围。
此外，优选使第一贯流风扇310和第二贯流风扇320的风轮直径相同，且使第一贯流风扇310的长度为第二贯流风扇320的两倍，如此使得第一贯流风扇310的额定风量为第二贯流风扇320的额定风量的两倍。
在一些附图未示意的替代性实施例中，也可使前面板110上共设置有两个出风口， 第一贯流风扇310对应的出风口的过流面积为第二贯流风扇320对应的出风口的过流面积的两倍，如此也能够实现多种风量档的送风模式。
在一些实施例中，如图5所示，换热器200优选为竖向延伸且开口朝前的“U”型换热器，第一贯流风扇310和第二贯流风扇320位于换热器200的前方内侧，或者说使两个贯流风扇被“U”型换热器三面包围，以在两个贯流风扇的运行时，使其三面吸风均经过换热器200，提升了换热器200的空气流通量，进而提升了其换热效率。
在一些替代性的实施例中，换热器200也可为平板状的换热器。
图6是图2的A处放大图；图7是图2中的风道分隔件500和轴承的示意性爆炸图；图8是图7中的风道分隔件500的底部结构示意图；图9是图5所示风道分隔件500、轴承以及两个贯流风扇的配合示意图。
如图2至图9所示，在本发明一些实施例中，骨架150内设置有风道组件400，其竖立在第一贯流风扇310和第二贯流风扇320的周向外侧，用于将空气从换热器200处向前引流至多个出风口112处。
如图2和图11所示，风道组件400包括竖向间隔设置的两个端板部430、440、蜗壳410以及蜗舌420。第一贯流风扇310的驱动电机318和第二贯流风扇320的驱动电机328分别安装于端板部430和端板部440。蜗壳410竖立设置且连接在端板部430和端板部440之间，蜗舌420同样竖立设置且连接在两个端板部430和端板部440之间，并与蜗壳410共同引导空气流向。
如图5至图9所示，风道分隔件500连接在蜗壳410和蜗舌420之间，并位于第一贯流风扇310与第二贯流风扇320之间，以将风道组件400限定的空间分隔为上下两部分，分别用于容纳第一贯流风扇310和第二贯流风扇320，以避免两个贯流风扇内的送风相互干扰。当然，直接设置两个相互独立的风道组件也可实现上述功能，但是本发明的风道组件400的结构更加简单，而且两个贯流风扇之间的衔接部位(该部位因无风扇，与之相对位的换热器部分的空气流动较差)更短，对换热器200的换热更加有利。
另外，风道分隔件500上安装有分别与第一贯流风扇310的转轴311和第二贯流风扇320的转轴321匹配的两个轴承520、550，以便安装两个贯流风扇。
风道分隔件500的一种可选的具体结构如图7至图9所示，风道分隔件500包括主体部510，其用于分隔风道组件400的空间。主体部510上具有开口朝下的筒状容纳空间(如图8)，其上开设有开孔513，轴承520从下位于容纳空间内，其上部伸出开孔513，轴承支架530在轴承520的下方顶住轴承520，使其保持位置，轴承支架530通过其上的卡扣532与主体部510上的卡孔512配合，完成安装。轴承520与第一贯流风扇310的转轴311配合。轴承支架540抵靠在轴承支架520下侧，轴承550被固定在轴承支架540与端板560之间，端板560上设置有开口563，以允许第二贯流风扇320的转轴321伸入。
图10是图2中的框架610的背部结构示意图；图11是以一水平面剖切风道组件400、风机以及导风装置600得到的剖视图；图12是导风装置600的运动机构的示意图；图13是摇杆630的结构示意图。图10仅示意出一个竖摆叶组，下侧的两个竖摆叶组被隐藏。
如图2至图6，图10至图13所示，在本发明一些实施例中，立式空调室内机的多个出风口112均为圆形，以使其更加美观。并且，立式空调室内机还还包括多个竖摆叶组和多个横摆叶组，用于引导各个出风口112的出风方向。多个竖摆叶组位于前面板110 的内侧，骨架150的前侧，与多个出风口一一匹配。每个竖摆叶组包括竖向延伸且分别可枢转地安装于骨架150的多个竖摆叶620，以枢转地实现左右摆风。具体地，骨架150前侧可设置一个框架610，将竖摆叶620安装在框架610上。多个竖摆叶620还可枢转至关闭出风口112的位置。
在上述实施例中，将竖摆叶620设置在前面板110内侧的框架620而非前面板610上，可方便竖摆叶620的设计、安装以及摆动。因为如果在圆形的出风口112处设置竖摆叶，多个竖摆叶的长短不一，其在出风口112处摆动时，两端也容易受到出风口112的弧形边缘的限制。
如图4，多个横摆叶组151在竖摆叶组后方与多个出风口112一一匹配。每个横摆叶组包括水平延伸且分别可枢转地安装于骨架150的多个横摆叶，以枢转地实现上下摆风。
如图11所示，优选使蜗壳410和蜗舌420连接至框架610的横向两端，以便将风直接引导至框架610上安装的摆叶620处，风向如图11中的箭头所示。
如图10至图13所示，每个竖摆叶组利用各自的驱动装置驱动竖摆叶摆动。每个驱动装置包括电机640、主摇杆630、连杆660以及多个摇杆630。其中，电机640安装于框架610。主摇杆630的一端固定连接于电机640的转轴，以受电机640的驱动而摆动，主摇杆630的另一端铰接于连杆660。多个摇杆630与多个竖摆叶620一一匹配，每个摇杆630的一端固定连接于竖摆叶620的枢转轴，另一端铰接于连杆660。需要调节出风口112的出风方向时，可控制电机640转动，使其带动主摇杆630摆动，主摇杆630带动连杆660平移，连杆660带动多个摇杆630同步摆动，多个摇杆630带动多个竖摆叶620同步枢转。电机640优选为转动过程可控性更好的步进电机。
横摆叶也可采用上述原理的驱动机构进行驱动，具体结构在此不再赘述。
在一些实施中，如图6所示，可使每个竖摆叶620的前表面为上下延伸的竖条纹结构，在多个竖摆叶620处于关闭出风口112的位置时，修饰两个相邻竖摆叶之间的缝隙，给用户一种两个竖摆叶紧密连接的视觉效果。
图14是图1中的人体检测装置800的结构示意图；图15是图14所示人体检测装置800安装于前面板110时的示意性剖视图。
如图1、图14和图15所示，在本发明一些实施例中，立式空调室内机还包括人体检测装置800。人体检测装置800配置成检测室内人体信息，人体信息包括人数、人体温度、人体位置。主控板配置成根据人体信息，控制第一贯流风扇310和第二贯流风扇320同时或择一开启，并控制第一贯流风扇310和第二贯流风扇320的风速或风向。
例如，主控板可根据人体检测装置800检测的室内人数控制两个贯流风扇的开启和关闭。当人数少于m时，仅开启第二贯流风扇320，当人数多于m少于n时，开启仅开启第二贯流风扇320，当人数多于n时，同时开启两个贯流风扇。并且，在一个或两个贯流风扇开启后，还可根据人数的多少控制风速。
主控板还可根据人体检测装置800检测的人体温度控制贯流风扇的开启数量或风速，当人体温度与人体舒适温度相差较大，主控板即判断人体较热或较冷，此时可多开启贯流风扇或加大其风速，以加快制冷或制热速度。
主控板还可根据人体检测装置800检测的人体位置控制贯流风扇的风向，以达到冷风避人，热风迎面的效果，是人体更加舒适。
人体检测装置800的具体结构如图14和图15所示。人体检测装置800可包括前侧敞开的安装盒840，球壳810、球壳驱动电机830以及温冷感传感器820。其中，安装盒840设置在前面板110的内侧。球壳810可绕一竖向轴线X1转动地设置在安装盒840内，且其前部通过前面板110上开设的圆孔凸伸出前面板110，以便实行检测。球壳810可由两个半球壳拼接而成，球壳810的前侧具有开孔812。球壳810驱动电机设置于安装盒840，用于驱动球壳810旋转。温冷感传感器820用于检测前述的人体信息，其固定于球壳810内且其探头位于开孔处，以允许光线进入探头。温冷感传感器820可为红外线传感器。
本发明实施例通过使球壳810带动温冷感传感器820旋转，能够极大增加其检测范围。如图1所示，人体检测装置800优选设置在前面板110的顶部区域，也是为了增大检测范围。
在一些实施例中，人体检测装置800还包括开口朝前的半球形遮挡板850。半球形遮挡板850与球壳810间隔地设置在球壳810后侧，并固定于安装盒840。人体检测装置800配置成在球壳810转动至使半球形遮挡板850完全遮挡温冷感传感器820的检测光路时，使温冷感传感器820仅检测室内温度。也就是说，在温冷感传感器820的探头转动到后侧时，其无法接收到室内空间人体发出的红外线信号，因此使其仅检测室内温度，避免误检测。
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。
