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
相比于壁挂式空调室内机，立式空调室内机的匹数更大，制冷制热能力更强，通常放置客厅等面积较大的室内空间中。
由于立式空调室内机的覆盖面积更大，需要其具有更强的远距离送风能力和强劲出风能力。现有产品为实现远距离送风，通常采用提高风机转速，以提高风速和风量的方式。但风机转速的提高会导致空调功率增加、噪声增大等一系列问题，影响用户体验。
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，以实现更好的远距离送风和强劲送风效果。
本发明的进一步的目的是要使立式空调室内机具有上扬出风效果。
特别地，本发明提供了一种立式空调室内机，包括：
壳体，其前侧具有第一送风口；
风道，设置在壳体内，具有进气口和朝向第一送风口的第一出气口，用于将壳体内的气流引导至第一送风口处；其中风道临近第一出气口顶部边缘和横向两侧边缘的内壁是从后向前延伸的平面，风道临近第一出气口底部边缘的内壁包括从后向前逐渐朝第一出气口的水平中心轴线倾斜的底部弧形面和自底部弧形面向前延伸的底部平面，且进气口的位置低于第一出气口；和
导流件，配置成与风道临近第一出气口的内壁之间限定出环形出风间隙，用于将气流导向环形出风间隙并使气流在导流件和风道内壁引导下流出第一送风口并逐渐向气流中心方向聚合。
可选地，导流件的外表面是由导流线绕水平轴旋转一周形成，导流线包括依次光滑相接的第一线段、内凹的第二弧形段、外凸的第三弧形段、外凸的第四弧形段、第五线段、外凸的第六弧形段和第七线段，第一线段、第五线段、第七线段为直线段或外凸的弧形段，并且第二弧形段、第三弧形段、 第四弧形段在从后向前方向逐渐远离水平轴，第七线段的终点与第一线段的起点处于同一水平轴上。
可选地，第一线段为外凸的弧形段，半径是第三弧形段的半径的0.4-0.6倍；
第二弧形段的半径是第三弧形段的半径的2.2-2.7倍；
第四弧形段的半径是第三弧形段的半径的0.4-0.8倍；
第五线段为直线段；
第六弧形段的半径是第三弧形段的半径的0.2-0.4倍；
第七线段为外凸的弧形段，半径是第三弧形段的半径的1.8-3.0倍。
可选地，第五线段为直线段；导流件配置成：第四弧形段的前部、第五线段、第六弧形段的后部限定的环形面与底部弧形面和底部平面之间限定出环形出风间隙，导流件的前端面的至少一部分超出第一送风口。
可选地，底部弧形面的弧线半径是第五线段与底部平面之间的竖直距离的0.9-1.1倍；
第四弧形段的两端切线的相交点与第六弧形段的两端切线的相交点的水平距离是第五线段与底部平面之间的竖直距离的1.5-2倍。
可选地，导流件的最宽处的宽度是风道的临近第一出气口顶部边缘的平面与底部平面之间的竖直距离的0.6-0.8倍。
可选地，立式空调室内机还包括：多个导叶，间隔设置于风道临近第一出气口的内壁处，每个导叶沿前后方向设置，以对流入环形出风间隙的气流在第一出气口的径向方向上进行梳理。
可选地，风道还配置成：在第一出气口的前端形成有环圈，环圈自第一出气口从后向前逐渐远离第一出气口的水平中心轴线倾斜至第一送风口处。
可选地，立式空调室内机还包括：
换热器，设置于壳体内；和
风机，设置于壳体内，用于促使室内空气进入壳体与换热器进行换热，然后经风道从第一送风口吹出。
可选地，第一送风口是开设于壳体的上部前侧的圆形口，第一出气口是开设于风道的上部前侧的圆形口；
壳体的中部和/或下部的横向一侧或两侧还开设有长条形的第二送风口，风道的中部和/或下部的横向一侧或两侧对应第二送风口还开设有长条形的 第二出气口。
本发明的立式空调室内机中，导流件配置成与风道临近第一出气口的内壁之间限定出环形出风间隙，如此一来，从进气口进入风道的气流(换热气流、新风气流等)流向第一出气口的过程中，将在导流件引导下将吹向风道内壁，最终流至环形出风间隙内。由于环形出风间隙的出风截面更小，使得其出风速度更高。风道临近第一出气口顶部边缘和横向两侧边缘的内壁是从后向前延伸的平面，而风道临近第一出气口底部边缘的内壁包括从后向前逐渐朝第一出气口的水平中心轴线倾斜的底部弧形面和自底部弧形面向前延伸的底部平面，使得高速气流在风道异形内壁和导流件的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，满足了立式空调室内机对远距离送风和强劲送风的需求。同时配套将进气口的位置低于第一出气口以使气流从下至上流向导流件，高速气流从下部冲到第一出气口处经过导流后仍具有一定的向上势头，因此整体出风会上扬，达到不直吹人的效果。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验，提高用户使用舒适性。
本发明的立式空调室内机中，导流件不仅与风道内壁限定出了环形出风间隙，达到提升风速的作用，同时也恰好能将气流导向环形出风间隙，或者说是强迫气流朝环形出风间隙流动，以迫使气流接受风道内壁的聚合引导，形成最终的聚合出风效果。本发明仅通过改进风道形状和增设一导流件就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。
进一步地，本发明还对导流件的形状进行了特别设计，使得导流件由包括依次光滑相接的第一线段、内凹的第二弧形段、外凸的第三弧形段、外凸的第四弧形段、第五线段、外凸的第六弧形段和第七线段的导流线绕水平中心轴线旋转一周形成，使得气流流动过程中的流动阻力更小，能量损耗和噪声更小，同时汇聚效应更明显，提升了出气口的聚合送风效果。
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

具体实施方式
本发明实施例提供了一种立式空调室内机，为分体式空调器的室内部分，用于调节室内空气，例如制冷/制热、除湿、引入新风等等。例如，立式空调室内机可为通过蒸气压缩制冷循环系统进行制冷/制热的空调器的室内机。

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壳体10、风道20和导流件30。壳体10前侧具有第一送风口11。第一送风口11用于将壳体10内的气流吹向室内，以调节室内空气。前述的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。第一送风口11的数量可为一个，也可为多个。壳体10上还可开设有进风口13，以用于引入室内空气。壳体10可由前机壳101和后机壳102组合而成。风道20设置在壳体10内，具有进气口23和朝向第一送风口11的第一出气口21，用于将壳体10内的气流引导至第一送风口11处；其中风道20临近第一出气口21顶部边缘和横向两侧边缘的内壁 252是从后向前延伸的平面，风道20临近第一出气口21底部边缘的内壁251包括从后向前逐渐朝第一出气口21的水平中心轴线倾斜的底部弧形面2511和自底部弧形面2511向前延伸的底部平面2512，且进气口23的位置低于第一出气口21。换言之，在临近第一出气口21处，沿着气流方向，风道20的过流截面先逐渐变小之后保持最小过流截面直至第一出气口21。导流件30配置成与风道20临近第一出气口21的内壁之间限定出环形出风间隙25，用于将气流导向环形出风间隙25并使气流在导流件30和风道20内壁引导下流出第一送风口11并逐渐向气流中心方向聚合(图2和图3用箭头示意了气流走向)。
本发明实施例的立式空调室内机中，导流件30配置成与风道20临近第一出气口21的内壁之间限定出环形出风间隙25，如此一来，从进气口23进入风道20的气流(换热气流、新风气流等)流向第一出气口21的过程中，将在导流件30引导下将吹向风道20内壁，最终流至环形出风间隙25内。由于环形出风间隙25的出风截面更小，使得其出风速度更高。风道20临近第一出气口21顶部边缘和横向两侧边缘的内壁252是从后向前延伸的平面，而风道20临近第一出气口21底部边缘的内壁251包括从后向前逐渐朝第一出气口21的水平中心轴线倾斜的底部弧形面2511和自底部弧形面2511向前延伸的底部平面2512，使得高速气流在风道20异形内壁和导流件30的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，满足了立式空调室内机对远距离送风和强劲送风的需求。同时配套将进气口23的位置低于第一出气口21以使气流从下至上流向导流件30，高速气流从下部冲到第一出气口21处经过导流后仍具有一定的向上势头，因此整体出风会上扬，达到不直吹人的效果。
本发明实施例的立式空调室内机中，导流件30不仅与风道20内壁限定出了环形出风间隙25，达到提升风速的作用，同时也恰好能将气流导向环形出风间隙25，或者说是强迫气流朝环形出风间隙25流动，以迫使气流接受风道异形内壁的聚合引导，形成最终的聚合出风效果。本发明仅通过改进风道20形状和增设一导流件30就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。
参考图4，导流件30的外表面是由导流线绕水平轴旋转一周形成，导流线包括依次光滑相接的第一线段(ab段)、内凹的第二弧形段(bc段)、 外凸的第三弧形段(cd段)、外凸的第四弧形段(de段)、第五线段(ef段)、外凸的第六弧形段(fg段)和第七线段(gh段)，第一线段(ab段)、第五线段(ef段)、第七线段(gh段)为直线段或外凸的弧形段，并且第二弧形段(bc段)、第三弧形段(cd段)、第四弧形段(de段)在从后向前方向逐渐远离水平轴，第七线段(gh段)的终点与第一线段(ab段)的起点处于同一水平轴上。本发明实施例还对导流件30的形状进行了特别设计，使得导流件30由包括依次光滑相接的第一线段(ab段)、内凹的第二弧形段(bc段)、外凸的第三弧形段(cd段)、外凸的第四弧形段(de段)、第五线段(ef段)、外凸的第六弧形段(fg段)和第七线段(gh段)的导流线绕水平中心轴线旋转一周形成，使得气流流动过程中的流动阻力更小，能量损耗和噪声更小，同时汇聚效应更明显，提升了出气口的聚合送风效果。此外，本发明实施例的导流件30可以是实心结构也可以是空心结构。
进一步地，本发明实施例通过对各线段的形状和大小关系进行优化，以强化上述效果。参考图2至图4，本发明实施例中，第一线段(ab段)为外凸的弧形段，半径是第三弧形段(cd段)的半径的0.4-0.6倍，例如0.4倍、0.5倍、0.6倍；第二弧形段(bc段)的半径是第三弧形段(cd段)的半径的2.2-2.7倍，例如2.2倍、2.5倍、2.7倍；第四弧形段(de段)的半径是第三弧形段(cd段)的半径的0.4-0.8倍，例如0.4倍、0.6倍、0.8倍；第五线段(ef段)为直线段；第六弧形段(fg段)的半径是第三弧形段(cd段)的半径的0.2-0.4倍，例如0.2倍、0.3倍、0.4倍；第七线段(gh段)为外凸的弧形段，半径是第三弧形段(cd段)的半径的1.8-3.0倍，例如1.8倍、2.5倍、3.0倍。从另一个角度，导流件30的外表面包括后端面37、第一环形导风面31、第二环形导风面32、第三环形导风面35、环形外周面33、环形过渡面36和前端面34，其中后端面37由第一线段(ab段)限定出，第一环形导风面31由第二弧形段(bc段)限定出，第二环形导风面32由第三弧形段(cd段)限定出，第三环形导风面35由第四弧形段(de段)限定出，环形外周面33由第五线段(ef段)限定出，环形过渡面36由第六弧形段(fg段)限定出，前端面34由第七线段(gh段)限定出。这里，当第五线段(ef段)为外凸的弧形段时，半径是第三弧形段(cd段)的半径的至少5倍，例如5倍。气流流动至导流件30时，先流经第一线段(ab段)，由于第一线段(ab段)为外凸的弧形段，使得气流容易受导流件30引导。之后流经第 二弧形段(bc段)，由于第二弧形段(bc段)为内凹设计，使气流流速加快，以远离第一出气口21的中心轴线地快速冲向风道20的内壁。第三弧形段(cd段)和第四弧形段(de段)均为外凸设计，以与风道20内壁更加接近，使得气流在流入环形出风间隙25过程中受到的阻力更小。第五线段(ef段)为直线段，可以对进入环形出风间隙25的气流进一步梳理出风流线，引导出风方向，减少出风阻力，提升出风强度，达到射流高速送风效果。第七线段(gh段)为外凸的弧形段的设计是作为导流件30的前端面34将其设计成外凸形状可以使导流件30本身具有一定的将气流向前汇聚的效果。第六弧形段(fg段)作为第五线段(ef段)和第七线段(gh段)的过渡区段，为外凸形状，以便气流从第五线段(ef段)光滑过渡至第七线段(gh段)。
如图2所示，在一些实施例中，第五线段(ef段)为直线段；导流件30配置成第四弧形段(de段)的前部、第五线段(ef段)、第六弧形段(fg段)的后部限定的环形面与底部弧形面2511和底部平面2512之间限定出环形出风间隙25，导流件30的前端面34的至少一部分超出第一送风口11。通过将环形出风间隙25主要由第五线段(ef段)的直线结构与底部弧形面2511和底部平面2512之间限定出，可保证明显的气流引导效果；导流件30的前端面34的至少一部分超出第一送风口11，可以对流出第一送风口11的气流继续向前汇聚，以进一步提升射流出风效果。
进一步地，本发明实施例通过对导流件30和风道20的尺寸关系进行优化，以强化上述效果。参考图2，底部弧形面2511的弧线半径R是第五线段(ef段)与底部平面2512之间的竖直距离d1的0.9-1.1倍，例如0.9倍、1.0倍、1.1倍，底部弧形面2511的圆角太小会导致出风损失过大，而圆角太大会使出风过于上偏，影响整体的出风距离。第四弧形段(de段)的两端切线的相交点与第六弧形段(fg段)的两端切线的相交点的水平距离L4是第五线段(ef段)与底部平面2512之间的竖直距离d1的1.5-2倍，例如1.5倍、1.8倍、2.0倍，足够长的近似直段可以引导出风更加平直进一步提升出风距离。导流件30的最宽处的宽度D1是风道20的临近第一出气口21顶部边缘的平面与底部平面2512之间的竖直距离L3的0.6-0.8倍，例如0.6倍、0.7倍、0.8倍，该尺寸主要会影响风量，倍数越小风量越大，倍数越大风量越小。继续参考图2，还可以对导流件30的最长处的长度L1进行限定，例如导流件30的最长处的长度L1是第四弧形段(de段)的两端切线的相交 点与第六弧形段(fg段)的两端切线的相交点的水平距离L4的2.9-3.1倍，例如2.9倍、3.0倍、3.1倍，使得导流件30整体与该近似直段共同引导向前平直出风。此外，可以将导流件30的最长处的长度L1限定为是风道20的第一出气口21正对应的后壁至前壁的长度L2的0.6-0.8倍，例如0.6倍、0.7倍、0.8倍，以便平衡风道20过风，保证第一送风口11的上下出风均匀。
现参考图5和图6，在一些实施例中，立式空调室内机还包括：多个导叶70，间隔设置于风道20临近第一出气口21的内壁处，每个导叶70沿前后方向设置，以对流入环形出风间隙25的气流在第一出气口21的径向方向上进行梳理。在第一出气口21出风时，两侧的出风没有受到有效引导，可能会导致上扬势头过大，整体出风较为散乱，通过设置导叶70后，气流会被再次被梳理，使出风集中度更高，风向上扬更合理。
在一些实施例中，风道20还配置成：在第一出气口21的前端形成有环圈24，环圈24自第一出气口21从后向前逐渐远离第一出气口21的水平中心轴线倾斜至第一送风口11处。通过设置环圈24可以使风道20与壳体10的配合更紧密，使经过环形出风间隙25的气流能更顺畅的流经第一出气口21和第一送风口11。
立式空调室内机还可包括换热器40和风机50。换热器40设置于壳体10内。风机50设置于壳体10内，用于促使室内空气进入壳体10与换热器40进行换热，然后经风道20从第一送风口11吹出。如图5至图7所示，风道20可包括前壳201、后壳202和接水盘203。前壳201的后侧和下侧敞开，第一出气口21开设于前壳201上。后壳202的前侧和下侧敞开，后壳202罩扣在前壳201后侧，共同构成下侧敞开的结构。接水盘203罩扣在前壳201和后壳202的下侧，以封闭其下侧的敞开口。风道20的进气口23开设于接水盘203上。将风道20分解为前壳201、后壳202和接水盘203三部分，方便对各部分独立加工制作，以更好地满足性能需求。如图5所示，可将换热器40设置在风道20内部，且安装于接水盘203上。换热器40可为两段式结构，两个换热段均为平板状且两者顶端相接，两个换热段的底端置于接水盘203上且分别位于进气口23的两侧。换热器40的这种倒“v”形结构可使其具有足够大的换热面积，且使其与进气口23向上流动的气流的接触更加充分，换热效率更高。接水盘203一方面用于承载换热器40，另一方面用于承接空调制冷时由换热器40表面滴落的冷凝水。可使风道20处于壳体10 的中上部，壳体10的下部开设有一个或多个进风口13，例如图7所示将进风口13开设于壳体10的后侧。可使风机50安装于风道20下方，且面对进气口23，以便将从进风口13进入壳体10下部空间的气流吹向风道20内部。风机50可如图6所示的双吸离心风机，或者也可为其他形式的风机。可以理解，当风机50为双吸离心风机时，配套设置有蜗壳51和电机52。
除此之外，还可使壳体10上设置其他送风口，以与第一送风口11配合使用，实现多种送风模式。例如图5至图7所示，风道20上具有两个第二出气口22。壳体10具有两个第二送风口12，以分别与两个第二出气口22匹配。两个第二送风口12分别开设于壳体10的横向两侧。例如，可使第一送风口11是开设于壳体10的上部前侧的圆形口，第一出气口21是开设于风道20的上部前侧的圆形口，使两个第二送风口12位于壳体10的中部或下部，以使各送风口送出的风在上下方向和左右方向错开，形成一种环抱送风的效果，使送风气流更加分散，提升立式空调室内机的制冷/制热速度和气流的舒适度。还可使每个第二送风口12为长度方向沿竖直方向设置的长条形，以利于其向斜下方送风，实现制热下吹，加快制热速度，提升制热舒适性。每个第二送风口12处可安装有导风机构，例如图7所示，每个第二送风口12处安装一个轴线沿竖直方向延伸的导风板60，以便转动地引导送风方向。
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。
