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
在空调制冷制热过程中，由于冷空气密度相对较大有下沉趋势，热空气密度相对较小有上升趋势。因此，空调在制冷时需要将较冷风尽量向上吹，在制热时需要将热风尽量朝地面吹，以使冷风或热风在室内空间扩散更加均匀，使制冷制热速度更快。
现有的立式空调室内机通常设置一个朝前的出风口，并利导风板、摆叶等导风结构引导送风气流的出风方向，实现上吹风或下吹风。但是，当前的各种导风结构导风角度比较有限，也仅能向斜上方或斜下方送风，冷风或热风难以抵达屋顶或地板区域，影响制冷或制热效果。
发明内容
本发明的目的是要提供一种克服上述问题或者至少部分地解决上述问题的立式空调室内机，以加强立式空调室内机的上吹风和/或下吹风效果。
本发明的进一步的目的是要使导风通道的出风量可调。
本发明的进一步的目的是要方便上吹模式和下吹模式的切换。
特别地，本发明提供了一种立式空调室内机，其包括：
机壳，其上开设有出风口；和
导风罩环，其套在所述机壳外周，以与所述机壳的外周面限定出导风通道，以用于引导从所述出风口流出的送风气流沿所述机壳的外周面向上和/或向下流动；且
所述导风罩环配置成使其至少部分区段与所述机壳外周面的间距可调，以便调节所述导风通道的出风量。
可选地，所述导风罩环包括：本体段，安装于所述机壳；和调节段，与所述出风口位置相对，且沿接近或远离所述机壳外周面的方向上可移动地安装于所述本体段，以便调节其与所述机壳外周面的间距。
可选地，立式空调室内机还包括：至少一个第一齿轮齿条机构，用于驱动所述调节段沿接近或远离所述机壳外周面的方向平移；且每个所述第一齿 轮齿条机构包括第一电机、相互啮合的第一齿轮和第一齿条，所述第一电机安装于所述本体段，所述第一齿轮设置于所述第一电机上，所述第一齿条设置于所述调节段上。
可选地，所述本体段可上下平移地安装于所述机壳；且所述导风罩环具有从其内侧表面朝所述机壳外周面凸出的分隔部，以将所述导风通道分隔为开口朝上的上通道和开口朝下的下通道，并配置成：可移动至使所述分隔部位于所述出风口上方位置，以由所述下通道将所述送风气流向下引导；或移动至使所述分隔部位于所述出风口下方位置，以由所述上通道将所述送风气流向上引导。
可选地，所述分隔部的上下表面均为内凹的弧面。
可选地，立式空调室内机还包括：至少一个第二齿轮齿条机构，用于驱动所述本体段上下平移，每个所述第二齿轮齿条机构包括第二电机、相互啮合的第二齿轮和第二齿条，所述第二电机设置于所述机壳上，所述第二齿轮设置于所述第二电机上，所述第二齿条沿竖直方向延伸且设置于所述本体段上。
可选地，所述出风口开设于所述机壳前侧；所述本体段横向两侧内壁分别具有竖直延伸的挡风条，用于阻挡所述送风气流向后流动；且每个所述挡风条上形成有一个所述第二齿条。
可选地，所述出风口为长度方向沿水平方向设置的长条形。
可选地，所述出风口处安装有用于将所述送风气流向上或向下引导的导风摆叶。
可选地，所述出风口位于所述机壳前侧上部区域，所述机壳的后侧下部开设有进风口；且所述立式空调室内机的还包括离心风机和板状换热器，所述离心风机设置在所述进风口前侧且轴线沿前后方向延伸，所述板状换热器从上至下逐渐向前倾斜地设置在所述机壳内的上部区域内。
本发明的立式空调室内机中，机壳外套设有一个导风罩环，导风罩环与机壳外周面限定出导风通道。机壳内部的送风气流(例如冷风或热风)从机壳的出风口吹出后，受到导风罩环的阻挡，无法直接水平地吹出，而是沿着机壳的外周面向上和/或向下吹出。由于送风气流紧贴着机壳外周面流动，形成附壁效应，能够沿机壳外周面顺利到达屋顶或地面，使立式空调室内机的制冷或制热效果更好。同时也能避免冷风或热风吹人导致人体不适。
并且，本发明的立式空调室内机中，导风罩环的至少部分区段与机壳外周面的间距可调。当该间距被调大后，导风通道的出风截面变大，出风更加顺畅，使出风量更大；当该间距被调小后，导风通道的出风截面变小，出风量将变小，本发明通过调节导风罩环实现了出风量的调节，满足了不同使用工况或情景对于出风量的调节需求。
进一步地，本发明的立式空调室内机中，导风罩环可上下平移地安装于机壳，分隔部将导风通道分隔为开口朝上的上通道和开口朝下的下通道，以使立式空调室内机具有上吹模式和下吹模式以供选择，以便提升制冷和制热效果。例如，当空调制热需要运行下吹模式时，将导风罩环移动至使分隔部位于出风口上方位置，由下通道将送风气流向下引导。当空调制冷需要运行上吹模式时，将导风罩环移动至使分隔部位于出风口下方位置，由上通道将送风气流向上引导，结构简单且调节方便。
进一步地，本发明的立式空调室内机中，使分隔部的上下表面均为内凹的弧面，以及使出风口处安装有用于将送风气流向上或向下引导的导风摆叶，都能使送风气流在从出风口吹出然后向上或向下转向时，方向变化地更加缓和，减少风力损失和噪声。

本发明实施例提供了一种立式空调室内机，用于调节室内空气，例如制冷、制热、除湿、引入新风等等。
图1是根据本发明一个实施例的立式空调室内机的结构示意图；图2是图1所示立式空调室内机的示意性剖视图；图3是图1所示立式空调室内机在导风罩环平移段前移后的状态示意图；图4是图3所示立式空调室内机的示意性剖视图。图中用箭头示意了送风气流的流动方向。
如图1至图4所示，本发明实施例的立式空调室内机一般性地可包括机壳10和导风罩环20。
机壳10上开设有出风口12，用于将机壳10内的送风气流排向室内。该送风气流可为立式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，或者在新风模式下引入的新风等等。机壳10整体为竖直延伸的柱状结构，出风口12可设置在机壳10的前侧上部区域，参考图2，也可设置在机壳10的其他位置，例如前侧中下部或者横向侧部。
导风罩环20套在机壳10的外周，以与机壳10的外周面限定出导风通道21。导风通道21用于引导从出风口12流出的送风气流沿机壳10的外周面向上和/或向下流动。具体地，送风气流(例如冷风或热风)从机壳10的 出风口12吹出后，在导风罩环20的内壁阻挡下，无法直接水平地吹出，将沿着机壳10的外周面向上和/或向下吹出。该处的向上和/或向下吹出指的是：可以使送风气流仅能向上吹出，或者仅能向下吹出，或者既能向上又能向下吹出。送风气流紧贴着机壳10的外周面流动，形成附壁效应，也可称为贴附效应。在附壁效应作用下，送风气流能够沿机壳10的外周面顺利到达屋顶或地面，使立式空调室内机的制冷或制热效果更好。同时也能避免冷风或热风吹人导致人体不适。
图5是图2所示立式空调室内机切换至下吹模式时的示意图。图1和图2示意了立式空调室内机运行上吹模式的情况，图5示意了立式空调室内机运行下吹模式的情况。
如图1和图2所示，立式空调室内机运行上吹模式时，送风气流贴合着机壳10的外周面向上流动。气流到达最顶端后，再向下散落，形成一种淋浴式送风效果。如图5所示，使立式空调室内机运行下吹模式时，送风气流贴合着机壳10外周面向下流动，可向下流动至地面，然后向上扬起，形成一种地毯式送风效果。可使送风气流流经的机壳10外周面区域为平坦表面，以利于送风气流更好地贴合着机壳10的外周面流动。
前述的导风罩环20为全环状，也即为一个完整的环圈。此外，也可使导风罩环20为半环状，或者为劣弧状，或者接近为直线型，使其能包围机壳10开设有出风口12的周向区段即可，而无需完全包围机壳10。
导风罩环还配置成：使导风罩环20的至少部分区段与机壳10的外周面的间距(图2、图4标示的B)可调，以便调节导风通道21的出风量。具体为，该间距B被调大后，导风通道21的出风截面变大，出风更顺畅，出风量更大；当该间距B被调小后，导风通道21的出风截面变小，出风量变小。本发明实施例通过调节导风罩环20实现了对出风量的调节，满足了不同使用工况或情景对于出风量的调节需求。
上述的导风罩环20的至少部分区段与机壳10的外周面的间距B可调，包括两种情况。具体为，使导风罩环20为一个整体，导风罩环20的整体(全部区段)与机壳10的外周面的间距可调。或者，使导风罩环20包括相拼接的多个区段(两个或更多)，使其中部分区段(一个或多个)可动，以使该区段与机壳10的外周面的间距B可调。
例如图1至图4所示，可使导风罩环20包括本体段201和调节段202。 本体段201安装于机壳10。调节段202与出风口12位置相对，且在接近或远离机壳10的外周面的方向上可移动地安装于本体段201，以便调节其与机壳10的外周面的间距。即，该调节段202即前述的与机壳10的外周面间距可调的“部分区段”。
具体如图2和图4所示，出风口12开设于机壳10的前侧，调节段202设置在出风口12前方，本体段201可前后移动地安装于本体段201。本体段201的前侧具有一段空缺，形成缺口，该缺口与出风口12相对，以用于容纳调节段202。调节段202的边缘形状与本体段201的缺口形状匹配(例如使两者均为矩形)，以便调节至恰好“嵌”在缺口处的嵌合位置，如图1，以使立式空调室内机外观更加美观。当空调处于关机状态时，可使调节段202处于该嵌合位置。
在一些实施例中，如图2和图5所示，可使导风罩环20的本体段201可上下平移地安装于机壳10。可以理解的是，本体段201上下平移时，调节段202也将随本体段201上下平移。并且，导风罩环20具有从其内侧表面朝机壳10的外周面凸出的分隔部23。分隔部23用于将导风通道21分隔为开口朝上的上通道212和开口朝下的下通道214。导风罩环20配置成：可移动至使分隔部23位于出风口12上方位置，以由下通道214将送风气流向下引导，如图5；或移动至使分隔部23位于出风口12下方位置，以由上通道212将送风气流向上引导，如图2。
如此一来，使立式空调室内机具有上吹模式和下吹模式以供系统或用户选择，使制冷和制热效果得到显著提升。例如，当空调制热需要运行下吹模式时，将导风罩环20移动至使分隔部23位于出风口12上方位置，由下通道214将送风气流向下引导，如图5。当空调制冷需要运行上吹模式时，将导风罩环20移动至使分隔部23位于出风口12下方位置，由上通道212将送风气流向上引导，如图2。
当然，也可使到风罩环20移动至上吹模式与下吹模式之间的位置，使从出风口12流出的送风气流的一部分从由上通道212向上引导，另一部分由下通道214向下引导，以同时向上和向下送风。
如图2所示，可使分隔部23的上下表面均为内凹的弧面，以便在送风气流在从出风口12吹出然后向上或向下转向时，使其方向变化地更加缓和，减少风力损失和噪声。
图6是图2的N-N剖视放大图；图7是图1所示立式空调室内机的示意性爆炸图。
如图6和图7所示，可使出风口12为长度方向沿水平方向的长条形。如此一来，可使出风口12横向跨度更大，利于将导风通道21设计为宽度(导风罩环20与机壳10外周面的间距B)较小、长度更长(即导风通道21沿机壳10周向方向的尺寸)的扁平状，以利于送风气流更多地贴合于机壳10的外周面，使贴附效果更好。而且，也使导风罩环20与机壳10距离更近，避免因设置导风罩环20使立式空调室内机变得更粗，以影响包装和美观。可如图4所示，进一步使导风通道21的宽度与出风口12的高度(出风口12在竖直方向的尺寸)之比在1/4至1/3之间，例如设置为0.3，以取得最优的贴附效果。
图8是图7的A处放大图，图9是图7的D处放大图。
如图6、图7和图9所示，立式空调室内机包括至少一个第一齿轮齿条机构，用于驱动调节段202沿接近或远离机壳10的外周面的方向平移。每个第一齿轮齿条机构包括第一电机71、相互啮合的第一齿轮81和第一齿条26，第一电机71安装于本体段201，第一齿轮81设置于第一电机71上，第一齿条26设置于调节段202上。第一电机71带动第一齿轮81转动时，使第一齿条26平移，以带动调节段202平移。具体地，第一齿轮齿条机构的数量优选为一个，第一电机71分别安装于本体段201缺口处的横向一边。此外，本体段201缺口处横向两边各设置一个滑轨282，调节段202横向两端各形成一个定位凸起281，每个定位凸起281可滑动地安装于一个滑轨282内，以对调节段202的平移运动进行导向。第一齿条26可形成于一个定位凸起281上。
如图6至图8所示，立式空调室内机包括至少一个第二齿轮齿条机构，以用于驱动导风罩环20的本体段201上下平移。每个第二齿轮齿条机构包括第二电机72、相互啮合的第二齿轮82和第二齿条251。第二电机72设置于机壳10上。第二齿轮82设置于第二电机72上。第二齿条251沿竖直方向延伸且设置于导风罩环20的本体段201上。第二电机72带动第二齿轮82转动时，使第二齿条251上下平移，以驱动导风罩环20的本体段201上下平移。具体地，第二齿轮齿条机构的数量优选为两个，其中两个第二电机72分别安装于机壳10的横向两侧，以使导风罩环20更加平稳地上下平移。
如图6和图7所示，可出风口12开设于机壳10前侧，使本体段201的内壁横向两侧分别具有竖直延伸的挡风条25，用于阻挡送风气流向后流动，使送风气流仅沿机壳10的前侧部分外周面向上或向下流动，避免其扩散地过于分散影响其风力。并且，每个挡风条25上形成有一个第二齿条251。即恰好利用挡风条25设置第二齿条251，结构更加巧妙。
如图2、图4和图7所示，可使出风口12处安装有用于将送风气流向上或向下引导的导风摆叶60。如此一来，在立式空调室内机运行上吹模式时，可利用导风摆叶60将送风气流向上引导；运行下吹模式时，可利用个导风摆叶60将送风气流向下引导，以使送风气流在从出风口12吹出然后向上或向下转向时，方向变化地更加缓和，减少风力损失和噪声。导风摆叶60可安装于框架61上，框架61直接安装于出风口12处。
如图7所示，可使出风口12位于机壳10的前侧上部区域，机壳10的后侧下部开设有进风口11。立式空调室内机的还包括离心风机50和板状换热器30。离心风机50设置在进风口11的前侧且轴线沿前后方向延伸，板状换热器30从上至下逐渐向前倾斜地设置在机壳10内的上部区域内。
如图7所示，机壳10由前壳101、后壳102、顶板103和底板104组成。出风口12开设于前壳101上，进风口11开设于后壳102上。蜗壳40设置在机壳10内且进口与进风口11相对，蜗壳40包括蜗壳本体41、蜗壳盖板42、引风圈45、衬垫44和接水盘43。板状换热器30位于蜗壳40的上方，其下端处于接水盘43的上方，以使其上的冷凝水滴落在接水盘43内。此外，机壳10上还可设置其余出风口，以进行常规模式的向前、左、右方向送风。
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。
