Description
本发明涉及空气调节装置技术领域，特别涉及一种壁挂式空调室内机及其送风结构。
随着经济的发展，空调已经成为人们日常生活中必不可少的家用电器。
在空调使用时，空调出风直吹至用户身上时，往往导致用户难受甚至生病，因而，用户越来越关注到空调使用健康的问题。空调直吹不健康一直都是用户使用时的痛点，尤其是家中有小孩和老人的场景；同时，空调直吹问题很大程度限制了空调制冷制热的范围，造成临近空调区域过冷或过热。
为了改善空调出风直吹的问题，现在一般在空调出风口处的导风板上增加一种引流的结构-在导风板内侧的前端设置逐渐增高的凸起部，将流经导风板内侧的气流形成向上方向的导流。但是，这种结构的导流效果不明显且送风距离有很大的限制。而且，该引流结构与导风板一体成型，不可拆卸，导致用户在某些情况下迫切希望直吹的场景受限于引流装置的存在，无法实现或者直吹效果差。

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本实施例壁挂式空调室内机的送风结构在现有正常风道的基础上，增加扬风风道，扬风风道位于正常风道的下方，扬风风道为弧形风道，扬风风道的结构能够借助空气在该风道中流动的惯性和离心力，使得气流在离开出风口时能够同时具有向前和向上的分速度：气流在进入扬风风道时，气体分子“被迫”做圆周运动，向心加速度会使得气体分子在离心方向上受到一个虚拟的力的作用；在气体分子离开风道，从出口流出时，由于惯性的存在，气体分子仍会在前和上方向上有力分量的作用，由于力分量的存在，气体分子在上和前方向上的运动会有加速度存在，运动的距离会增加，空调器送风的距离和扬风的高度得到很大的提升，能够有效避免直吹。本实施例还设置有风道切换装置，通过风道切换装置能够使得空调的出风在正常风道和扬风风道之间进行切换，能够根据需求选择正常出风或者扬风出风，满足了用户的多种需求。
下面结合附图1-4对壁挂式空调室内机的送风结构进行具体说明：
一种壁挂式空调室内机的送风结构，包括出风口、正常风道、扬风风道和风道切换装置，在出风口处设置有对气流进行导向的导风板，下面对送风结构的各个组成部分进行具体的说明。
出风口11位于空调器的壳体1上，用于将空调器产生的气流排出至空调器所在的空间。
在壳体1上还设置有进风口12，空调器所在空间的空气通过进风口12进入空调器的壳体1内。
在壳体1内设置有换热器（图中未示出）和风机2，换热器和风机2的设置可与现有技术相同，此处不再赘述。
正常风道3与出风口11连通，壳体1内经过换热器换热的空气在风机2的作用下可通过正常风道3后从出风口11排出至空调器所在的空间。
正常风道3包括进风端31和出风端，出风端也即出风口11，进风端31靠近风机2。
正常风道3能够实现空调器的正常出风，并可通过设置在出风口11处的导风板6进行导向，用户可根据需求设置导风板6的导风方向。
扬风风道4与出风口11连通，扬风风道4位于正常风道3的下方，扬风风道4为弧形风道。气流在进入扬风风道4时，气体分子“被迫”在弧形风道内做圆周运动，向心加速度会使得气体分子在离心方向上受到一个虚拟的力的作用；在气体分子离开扬风风道4，从出风口11流出时，由于惯性的存在，气体分子仍会在前和上方向上有力分量的作用，由于力分量的存在，气体分子在上和前方向上的运动会有加速度存在，运动的距离会增加，空调器送风的距离和扬风的高度得到很大的提升，能够有效避免直吹。气流从出风口11吹出后的流动方向如图5所示。
优选的，扬风风道4内的气流的运动方式为圆周运动，以最大化的提高空调器送风的距离和扬风的高度。
扬风风道4具有进风端41和出风端42。优选的，进风端41和出风端42均与正常风道3相接，出风端42靠近出风口11，进风端41靠近风机2，此种设置方式可以避免扬风风道4占用正常风道3的空间。
扬风风道4的出风方向位于出风口11内，也即，扬风风道4的出风端的切线与出风口11相交。因而，扬风风道4的出风能够顺利从出风口11排出，不会被正常风道3所遮挡。
为了进一步提高送风距离和扬风的高度，沿扬风风道4的出风方向，扬风风道4的横截面积逐渐减小，会使气流在扬风风道4内进一步加速；通过控制扬风风道4的收窄，实现本实施例扬风风道4出风端42的风速要高于横截面积相同的风道出风的风速，因而，本实施例使得扬风风道4喷出的气流具有较大的速度，使得其在向前和向上的速度分量更大。
具体的，送风结构包括正常风道上壁32、正常风道下壁33、弧形扬风风道上壁43和弧形扬风风道下壁44。
正常风道3包括正常风道上壁32和正常风道下壁33，正常风道上壁32和正常风道下壁33相对形成正常风道3。正常风道上壁32位于壳体1的内侧，并延伸至靠近风机2的位置，通常，在正常风道上壁32的上方安装有换热器的接水盘。正常风道上壁32一般为贯流风机的蜗舌，正常风道下壁33一般为贯流风机的背板。
扬风风道4包括扬风风道上壁43和扬风风道下壁44，扬风风道上壁43和扬风风道下壁44相对形成扬风风道4。
扬风风道4的进风端41和出风端42均开设在正常风道下壁33上。
位于扬风风道4的进风端41和出风端42之间的正常风道下壁33和弧形扬风风道上壁43形成用于分隔正常风道3和扬风风道4的分隔件433。
其中，正常风道下壁33和扬风风道上壁43位于分隔件433上。
分隔件433包括正常风道下壁33和弧形扬风风道上壁43。分隔件433可以为半圆柱形，分隔件433的两端与壳体1的两个侧面板相接。
扬风风道下壁44位于壳体1的内侧，扬风风道下壁44为弧形。
优选的，扬风风道上壁43和扬风风道下壁44均为圆弧形。
风道切换装置5，用于调控正常风道3导通、扬风风道4截止以使空调室内机处于正常送风状态；用于调控正常风道3截止、扬风风道4导通以使空调室内机处于扬风送风状态。因而，本实施例可以根据用户需求进行正常风道3和扬风风道4之间进行选择，选择正常风道3时，出风口11为正常出风状态，此时通过导风板6进行出风方向的调节；选择扬风风道4时，导风板6打开，出风口11为扬风出风状态。
优选的，风道切换装置5为可转动地安装在分隔件433上的切换导板。风道切换装置5位于壳体1的两个侧面板之间，风道切换装置5的长度与分隔件433的长度相适配。
具体的，切换导板包括导板本体51、位于导板本体51两端的安装端52和自由端53，导板本体51的厚度自安装端52向自由端53逐渐减薄，可以减小切换导板在切换过程中对气流的阻挡，使切换导板在切换过程中对气流的影响降低到最小。自由端53在远离导板本体51的方向上逐渐减薄，以进一步减小切换导板对气流的阻挡。
导板本体51包括能够将气流导向至正常风道3的正常导风面511和能够将气流导向至扬风风道4的扬风导风面512。
优选的，正常导风面511为内凹的弧面，在切换导板截止扬风风道4时，切换导板与正常风道3的正常风道下壁33相接并形成圆滑的曲面，以便于正常风道3的出风。
扬风导风面512包括靠近自由端53的内凹部5121和靠近安装端52的外凸部5122，在切换导板截止正常风道3时，切换导板与正常风道3的正常风道上壁32相接，扬风导风面512与正常风道下壁32相对，形成一个缩口，以利于气流流向扬风风道4。
导风板6位于出风口11处，导风板6包括转动端61和出风端62，转动端61通过转轴安装在壳体1的两个侧面板上。
为了提高扬风效果，导风板6自转动端61向出风端62逐渐减薄，且导风板6上表面的弯度小于下表面的弯度，因而，气流在流经导风板6时，由于导风板6的形状结构，会产生“上洗“的气流，使得气流在流经导风板6后会受到斜向上的作用力，以进一步提高扬风效果。
出风端62在远离导风板6的方向上逐渐减薄并最终减薄为尖锐的薄片。
出风端62与导风板6呈一定角度，出风端62比导风板6偏离出风口11。
出风端62与导风板6，出风端62的设置可以防止导风板6上下两侧的气流在导风板6尾段发生上下方气流剧烈耦合，本实施例将出风端62设置一个极尖的小挡板，可以减弱上下侧气流的影响。
优选的，在扬风出风状态时，导风板6打开角度为导风板6的出风端62接近于水平面的位置，其中，导风板6的出风端62是指导风板转动过程中转动行程最大的一端。
本实施例通过扬风风道4配合导风板6，能够实现很好的扬风效果，避免直吹。
一种壁挂式空调室内机，包括壳体1和位于壳体1内的换热器（图中未示出）、风机2，壳体1上设置有进风口12和出风口11，空调器室内机包括送风结构。
下面结合附图1-4对壁挂式空调室内机的送风结构进行具体说明：
一种壁挂式空调室内机的送风结构，包括出风口、正常风道、扬风风道和风道切换装置，在出风口处设置有对气流进行导向的导风板，下面对送风结构的各个组成部分进行具体的说明。
出风口11位于空调器的壳体1上，用于将空调器产生的气流排出至空调器所在的空间。
在壳体1上还设置有进风口12，空调器所在空间的空气通过进风口12进入空调器的壳体1内。
在壳体1内设置有换热器（图中未示出）和风机2，换热器和风机2的设置可与现有技术相同，此处不再赘述。
正常风道3与出风口11连通，壳体1内经过换热器换热的空气在风机2的作用下可通过正常风道3后从出风口11排出至空调器所在的空间。
正常风道3包括进风端31和出风端，出风端也即出风口11，进风端31靠近风机2。
正常风道3能够实现空调器的正常出风，并可通过设置在出风口11处的导风板6进行导向，用户可根据需求设置导风板6的导风方向。
扬风风道4与出风口11连通，扬风风道4位于正常风道3的下方，扬风风道4为弧形风道。气流在进入扬风风道4时，气体分子“被迫”在弧形风道内做圆周运动，向心加速度会使得气体分子在离心方向上受到一个虚拟的力的作用；在气体分子离开扬风风道4，从出风口11流出时，由于惯性的存在，气体分子仍会在前和上方向上有力分量的作用，由于力分量的存在，气体分子在上和前方向上的运动会有加速度存在，运动的距离会增加，空调器送风的距离和扬风的高度得到很大的提升，能够有效避免直吹。气流从出风口11吹出后的流动方向如图5所示。
优选的，扬风风道4内的气流的运动方式为圆周运动，以最大化的提高空调器送风的距离和扬风的高度。
扬风风道4具有进风端41和出风端42。优选的，进风端41和出风端42均与正常风道3相接，出风端42靠近出风口11，进风端41靠近风机2，此种设置方式可以避免扬风风道4占用正常风道3的空间。
扬风风道4的出风方向位于出风口11内，也即，扬风风道4的出风端的切线与出风口11相交。因而，扬风风道4的出风能够顺利从出风口11排出，不会被正常风道3所遮挡。
为了进一步提高送风距离和扬风的高度，沿扬风风道4的出风方向，扬风风道4的横截面积逐渐减小，会使气流在扬风风道4内进一步加速；通过控制扬风风道4的收窄，实现本实施例扬风风道4出风端42的风速要高于横截面积相同的风道出风的风速，因而，本实施例使得扬风风道4喷出的气流具有较大的速度，使得其在向前和向上的速度分量更大。
具体的，送风结构包括正常风道上壁32、正常风道下壁33、弧形扬风风道上壁43和弧形扬风风道下壁44。
正常风道3包括正常风道上壁32和正常风道下壁33，正常风道上壁32和正常风道下壁33相对形成正常风道3。正常风道上壁32位于壳体1的内侧，并延伸至靠近风机2的位置，通常，在正常风道上壁32的上方安装有换热器的接水盘。正常风道上壁32一般为贯流风机的蜗舌，正常风道下壁33一般为贯流风机的背板。
扬风风道4包括扬风风道上壁43和扬风风道下壁44，扬风风道上壁43和扬风风道下壁44相对形成扬风风道4。
扬风风道4的进风端41和出风端42均开设在正常风道下壁33上。
位于扬风风道4的进风端41和出风端42之间的正常风道下壁33和弧形扬风风道上壁43形成用于分隔正常风道3和扬风风道4的分隔件433。
其中，正常风道下壁33和扬风风道上壁43位于分隔件433上。
分隔件433包括正常风道下壁33和弧形扬风风道上壁43。分隔件433可以为半圆柱形，分隔件433的两端与壳体1的两个侧面板相接。
扬风风道下壁44位于壳体1的内侧，扬风风道下壁44为弧形。
优选的，扬风风道上壁43和扬风风道下壁44均为圆弧形。
风道切换装置5，用于调控正常风道3导通、扬风风道4截止以使空调室内机处于正常送风状态；用于调控正常风道3截止、扬风风道4导通以使空调室内机处于扬风送风状态。因而，本实施例可以根据用户需求进行正常风道3和扬风风道4之间进行选择，选择正常风道3时，出风口11为正常出风状态，此时通过导风板6进行出风方向的调节；选择扬风风道4时，导风板6打开，出风口11为扬风出风状态。
优选的，风道切换装置5为可转动地安装在分隔件433上的切换导板。风道切换装置5位于壳体1的两个侧面板之间，风道切换装置5的长度与分隔件433的长度相适配。
具体的，切换导板包括导板本体51、位于导板本体51两端的安装端52和自由端53，导板本体51的厚度自安装端52向自由端53逐渐减薄，可以减小切换导板在切换过程中对气流的阻挡，使切换导板在切换过程中对气流的影响降低到最小。自由端53在远离导板本体51的方向上逐渐减薄，以进一步减小切换导板对气流的阻挡。
导板本体51包括能够将气流导向至正常风道3的正常导风面511和能够将气流导向至扬风风道4的扬风导风面512。
优选的，正常导风面511为内凹的弧面，在切换导板截止扬风风道4时，切换导板与正常风道3的正常风道下壁33相接并形成圆滑的曲面，以便于正常风道3的出风。
扬风导风面512包括靠近自由端53的内凹部5121和靠近安装端52的外凸部5122，在切换导板截止正常风道3时，切换导板与正常风道3的正常风道上壁32相接，扬风导风面512与正常风道下壁32相对，形成一个缩口，以利于气流流向扬风风道4。
导风板6位于出风口11处，导风板6包括转动端61和出风端62，转动端61通过转轴安装在壳体1的两个侧面板上。
为了提高扬风效果，导风板6自转动端61向出风端62逐渐减薄，且导风板6上表面的弯度小于下表面的弯度，因而，气流在流经导风板6时，由于导风板6的形状结构，会产生“上洗“的气流，使得气流在流经导风板6后会受到斜向上的作用力，以进一步提高扬风效果。
出风端62在远离导风板6的方向上逐渐减薄并最终减薄为尖锐的薄片。
出风端62与导风板6呈一定角度，出风端62比导风板6偏离出风口11。
出风端62与导风板6，出风端62的设置可以防止导风板6上下两侧的气流在导风板6尾段发生上下方气流剧烈耦合，本实施例将出风端62设置一个极尖的小挡板，可以减弱上下侧气流的影响。
优选的，在扬风出风状态时，导风板6打开角度为导风板6的出风端62接近于水平面的位置，其中，导风板6的出风端62是指导风板转动过程中转动行程最大的一端。
本实施例通过扬风风道4配合导风板6，能够实现很好的扬风效果，避免直吹。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。
