第二方面，本申请实施例提供了一种暖通设备，该空调器包括室外机和如上所述的室内机，所述室外机与所述室内机相连接。
基于本申请实施例的室内机和暖通设备，通过在蜗舌上间隔设置有多个导流筋，且相邻两个导流筋之间限定出导流槽，并在片主体的尾端上间隔设置有多个出风部，相邻两个出风部限定出出风槽，同时尾端与导流筋相对的叶片的出风部与导流槽相对，且该叶片的出风槽与导流筋相对，使得本实施例的室内机至少具有三个方面的效果：
一、由于风量较大风流的风速较高，会使得动压变大而静压降低，风量较小的风流的风速较低，会使得动压变小而静压升高，而静压较小的风流便会流向静压大的风流，也即风量大的风流会流向风量较小的风流，这时候便会导致产生涡流，进而产生出噪音。基于此，本申请实施例通过出风部与导流槽的相对设置，以及出风槽与导流筋的相对设置，使得出风部至导流槽的槽底壁的距离与导流筋至出风槽的槽底壁的距离尽可能一致，如此，能够使得叶片送出至蜗舌的风流在风轮的轴向上风量尽可能地处处相等，减少风量大的风流流向风量较小的风流的情况发生，如此，能够减少涡流的产生，便能够降低噪音的产生可能性。
二、流经叶片表面的风流中，靠近叶片表面的气流在受到叶片的表面的障碍下风速会降低，形成一层边界层，而边界层内的风流风速较低，而边界层之外的风流风速较高，这会导致易于在边界层处产生涡流，而本申请实施例在叶片形成有出风槽，出风槽能够打破边界层的排列，使得边界层内的风流无法形成完整的涡流，从而风流能更均匀地分布在叶片表面，以降低涡流产生的可能性，从而起到降低噪音的效果。
三、风轮送出的风流所产生的涡流，在流经蜗舌时，会被设置于蜗舌上的多个导流筋进行分隔，使得尺度较大的涡流会被打散为多个尺度较小的涡流，如此有利于将噪音离散为宽频噪音，降低噪音的影响效果，改善音质。并且，在多个导流筋的导流作用下，能够减少风流在风轮轴向方向上的流动，从而能够降低风流在流向出风口的流动过程中的能量损失。

请参阅图1，本申请实施例提出一种暖通设备。该暖通设备包括室内机1和室外机(图中未示出)，室内机1与室外机通过线缆、管路等相连，以联合运作起到调节室内环境的作用。可以理解地，室内机1被设置在室内，并通常采用吊顶的形式进行安装，用于对室内送风，其中室内机1可以为风管机。请结合参阅图1至图3，室内机1可以包括风道组件10、风机91、换热器92及电控盒93。
其中，风道组件10用于构造适用于暖通设备的室内机1的风道，以供气体流动。具体地，风道组件10的外轮廓可以是大致呈长方体状，而具有上下方向、前后方向以及左右方向，上下方向、前后方向以及左右方向两两呈夹角设置。请结合参阅图3，风道组件10内形成有依次相连通的风机腔11、扩压腔12以及换热腔13，并形成有连通风机腔11的回风口14和连通换热腔13的出风口15，而使风流能够从回风口14进入风道组件10内，并依次经风机腔11、扩压腔12及换热腔13，最后从出风口15流出。需要说明的是，本申请实施例不限制室内机1的壳体构成，既可以是风道组件10本身，也可以在风道组件10之外设置外壳。
下面结合附图对风道组件10的相关结构作出解释说明。请结合参阅图2至图3，在本申请的一些实施例中，为便于室内机1的装配，风道组件10包括上壳体20和下壳体30。上壳体20与下壳体30连接，以拼接形成上述壳体。其中，上壳体20和下壳体30分别可以是铝合金或不锈钢等金属材质，以满足高强度和耐腐蚀等要求，或者，上壳体20和下壳体30也可以采用塑料材质以实现壳体的轻量化，本申请对此不作限制。例如，壳体可以采用上壳体20为金属材质，而下壳体30为塑料材质的搭配组合。此外，本申请实施例对上壳体20和下壳体30的连接方式不作限定，它们可以单独或组合地通过卡接、铆接、焊接及螺栓连接等方式进行连接。
具体来说，请结合图2，上壳体20包括上盖20a和两个侧围板70。两个侧围板70在左右方向上间隔设置，限定出上壳体20的宽度；上盖20a大体设置在两个侧围板70的上方，并沿着前后方向延伸，上盖20a沿左右方向的两侧分别与两个侧围板70相连接；如此，上盖20a和两个侧围板70拼接形成罩壳状的上壳体20。当然，上盖20a与侧围板70可以是一体设置也可以是分体设置的，二者可采用相同或不同的材料制成，并采用卡接、铆接、焊接及螺栓连接等方式进行连接，本申请在此不多赘述。相应地，下壳体30与上盖20a在上下方向上间隔设置，并也沿着前后方向延伸设置，下壳体30设置在两个侧围板70之间，且下壳体30沿左右方向的两侧分别与两个侧围板70相连接，这样，上壳体20、下壳体30以及两个侧围板70拼接形成上述壳体。
请参阅图3，上壳体20与下壳体30的至少其中之一形成上述回风口14，即是说，回风口14可以是设置在上壳体20或下壳体30，也可以是由上壳体20和下壳体30构设形成。
请继续参阅图3至图5，沿前后方向由后至前地，上盖20a包括依次连接的风机腔上壳21、扩压腔上壳22以及换热腔上壳23，下壳体30则包括依次连接的蜗舌40、扩压腔下壳50以及接水盘60。风机腔上壳21与蜗舌40在前后方向上间隔设置，并至少与蜗舌40和侧围板70限定出风机腔11，也即蜗舌40限定出风机腔11的部分腔壁。扩压腔上壳22与蜗舌40、扩压腔下壳50及侧围板70共同围合形成扩压腔12。换热腔上壳23与接水盘60、侧围板70围设形成换热腔13。进一步地，请参阅图6，下壳体30还包括多个导流筋42，多个导流筋42间隔地凸设于蜗舌40，且相邻两个导流筋42之间限定出导流槽43。可以理解的是，风机91所送出的风流在导流筋42和导流槽43的导引下能流向扩压腔12。
请参阅图3，沿扩压腔12至换热腔13的方向上，扩压腔12呈渐扩设置。在一些实施例中，在远离接水盘60的方向上，扩压腔下壳50向上倾斜设置，扩压腔上壳22可以是水平设置的，或者扩压腔上壳22也可以是贴合气流流线的弧线设置。总之，沿靠近换热腔13的方向，扩压腔上壳22与扩压腔下壳50之间的距离逐渐增大，从而使扩压腔12内气体的横向流通面积逐渐变大，而随着气体的横向流通面积逐渐变大，气体的流速逐渐降低，动压变小。动压较小的气体流速使得气体在经过换热腔13时能够与换热器92充分的进行热交换。此外，根据伯努利定律，气体的动压变小的同时，气体的静压变大，因而气体在从出风口15流出时的静压较大。较大的静压能够帮助从出风口15流出的气流更有效的克服空气阻力，从而能够到达相对于出风口15更远处，使室内机1具有相当的送风距离。
而为了使风机91抽风更顺畅，回风口14与风机腔11的入口处的距离应尽量的短，以缩短气流行程。可选地，回风口14可正对风机腔11的入口处设置。比如，本申请实施例中，上盖20a(风机腔上壳21)沿上下方向的下端与接水盘60间隔设置，上盖20a的下端至少与接水盘60限定出回风口14。这一实施例中，回风口14位于风机腔11的下方，且气体在进入回风口14后，能够以较短的路径流入风机腔11，如此能够有效减少气体的损耗，有利于提高抽风顺畅性。
请参阅图3，在一些实施例中，室内机1还包括保温层80，具体包括上保温层81和下保温层83。上保温层81可以是连接在换热腔上壳23靠近换热器92的一侧，下保温层83可以是连接在接水盘60背离换热器92的一侧，如此，通过上保温层81和下保温层83，可以起到一定程度上保持风道组件10内的温度，降低室内机1内的能量通过上壳体20以及下壳体30向外散发的概率。
请结合参阅图1至图3，在一种结构形式中，下壳体30还包括格栅98，格栅98至少连接扩压腔下壳50和风机腔上壳21的下端，其上形成有多个通孔，穿过回风口14的气体能够通过多个通孔进入风机腔11。设置格栅98能够有效避免较大的异物进入风机腔11，影响风机91的运行。格栅98呈网格状设置，以尽可能地增大通孔，减少对气流的影响。
可选地，格栅98整体可以呈弧形设置；或者，格栅98还可以包括呈夹角设置的第一格栅981和第二格栅983，第一格栅981连接风机腔上壳21的下端并沿前后方向向前延伸设置，第二格栅983连接第一格栅981远离风机腔上壳21的一端，并向上延伸设置，第二格栅983远离第一格栅981的一端连接扩压腔下壳50。其中，第一格栅981和第二格栅983可以为一体结构，整体性较好且易于加工，或者第一格栅981和第二格栅983还可以是分体结构，并通过螺栓连接或焊接等方式连接。呈夹角设置的第一格栅981和第二格栅983距离风机91较远，风机91的进风侧与格栅98之间有充分的空间，更便于风机91抽风。
请结合参阅图2至图3，风机91设置在风机腔11内，且能够抽取回风口14的风流，并对其做功使其以较快的流速流至扩压腔12，为上述风道的风流循环提供动力。风机91可以是贯流风机91、离心风机91或者轴流风机91等等，其中，贯流风机91具有节能、风量大、噪音低、安装简单的优点。以贯流风机91为例，风机91可以包括有风轮911和电机913，风轮911可以是呈长筒状设置，并收容于风机腔11内，电机913设置在风轮911的一端并与壳体的侧围板70相连接，且电机913的输出轴连接风轮911，以驱动风轮911进行转动，使得风轮911能够被配置为可转动地收容于风机腔11内。
请结合参阅图2至图3，换热器92收容于换热腔13内，用于与流经换热腔13并穿过换热器92的气体进行换热，起到对气体进行制冷或制热的作用。比如，换热器92内穿设有多条冷媒管，气体在穿过换热器92时与管内的冷媒换热，从而温度降低，形成低温空气。而为了增大换热器92的换热面积，换热器92可以是呈V形、弧形或者波浪形设置，并由一个单独的换热片构成，或由多个换热片组合而成。
电控盒93内设置有电控板组件，电控板组件上集成了多种电子元器件，用于电连接风机91等装置，并用于对室内机1的整体运行状况进行总体控制。不可避免地，电子元器件在运行过程中会产生较多的热量。本申请实施例中，电控盒93可以设置在风道组件10所形成的风道内，或贴近风道设置，以藉由风道内风流对电控盒93进行一定程度的散热，避免电控板组件过热所造成的器件运行故障或损坏等，提高室内机1的运行稳定性，延长使用寿命。
请结合参阅图7至图9，风轮911包括多个叶片914以及两个端板918，多个叶片914沿风轮911的环向间隔排布，并且每一叶片914安装在两个端板918之间，电机913的输出轴连接于任一端板918，以通过驱动侧板转动而实现带动叶片914的转动。其中，当风轮911为塑料材质时，可以通过一体注塑成型的形式加工制成，也即叶片914与端板918均为塑料材质且整体为一体结构，如此使得叶片914与端板918的连接更为牢固，且风轮911的整体重量较轻，对壳体所造成的负荷较小。当然，风轮911也可以为金属材质，例如铝合金材质，具有强度较佳等优点，本实施例对此不作限制。
进一步地，请参阅图9，每一叶片914的横截面形状可以是均呈翼型状，翼型状可以优化风流在叶片914的表面上的分布，使叶片914表面的风流更加均匀，降低风流在叶片914表面的湍流度，从而提高风轮的气动性能，提高风轮911运行时的稳定性。示范性地，翼型状可以具体是对称翼型、平凸翼型或者凹凸翼型等等形状，本实施例对此不作限制。
请结合参阅图7至图9，在一种结构形式中，叶片914包括片主体915以及多个出风部916，片主体915具有在其延伸方向上相背的首端和尾端，且相邻两个片主体915之间的间隙形成为风流通道，且该风流通道具有进口和出口，可以理解的是，相邻两个片主体915的首端之间配合限定出进口，该进口可以供回风口14处的风流进入风流通道，而相邻两个片主体915的尾端之间配合限定出出口，该出口可以供风流由风流通道流出。多个出风部916间隔设于尾端上，且相邻两个出风部916之间限定出出风槽917。如此，当风流由风流通道的出口流出时，分别流经出风部916和出风槽917后，再流向蜗舌40。
出风槽917的横截面形状与导流筋42的横截面形状相适配，具体地，每一出风槽917的横截面形状可以是均呈梯形、三角形或者矩形，相对应地，每一导流筋42的横截面形状可以是对应均呈梯形、三角形或者矩形，本申请对此不作限制。如此，在风道组件10的前后方向上，能够使得出风槽917与导流筋42之间处处距离相等。
其中，请参阅图10，在风轮911转动至任一角度的状态下，沿风道组件10的前后方向，尾端与导流筋42相对的叶片914的出风部916与导流槽43相对设置，且，该叶片914的出风槽917与导流筋42相对设置。可以理解的是，风轮911的转动角度范围在0度至360度之间，因此，风轮911可以是转动至该转动角度范围内的任一角度，例如0度、90度、180度、270度或者360度等等，而当风轮911转动任一角度并停留在该角度下时，沿前后方向，尾端与导流筋42相对的叶片914，其出风部916与导流槽43相对，且其出风槽917与导流筋42相对，如此，风轮911无论转动至任一角度并停留时，均会存在有叶片914的出风部916是与导流槽43相对，且出风槽917与导流筋42相对的情况，从而该叶片914的出风部916所送出的风流会尽可能地流向所对应的导流槽43，且流经出风槽917而被送出的风流也会尽可能地流向所对应的导流筋42，也即无论风轮911转动任一角度，都会有尾端与导流筋42相对的叶片914进行送风。需要说明的是，此处的相对可以是部分相对或者完全相对，本申请在此不作限制。
综上，通过在蜗舌40上间隔设置有多个导流筋42，且相邻两个导流筋42之间限定出导流槽43，并在片主体915的尾端上间隔设置有多个出风部916，相邻两个出风部916限定出出风槽917，同时尾端与导流筋42相对的叶片914的出风部916与导流槽43相对，且该叶片914的出风槽917与导流筋42相对，使得本实施例的室内机1至少具有三个方面的效果：
一、由于风量较大风流的风速较高，会使得动压变大而静压降低，风量较小的风流的风速较低，会使得动压变小而静压升高，而静压较小的风流便会流向静压大的风流，也即风量大的风流会流向风量较小的风流，这时候便会导致产生涡流，进而产生出噪音。基于此，本申请实施例通过出风部916与导流槽43的相对设置，以及出风槽917与导流筋42的相对设置，使得出风部916至导流槽43的槽底壁的距离与导流筋42至出风槽917的槽底壁的距离尽可能一致，如此，能够使得叶片914送出至蜗舌40的风流在风轮911的轴向上风量尽可能地处处相等，减少风量大的风流流向风量较小的风流的情况发生，如此，能够减少涡流的产生，便能够降低噪音的产生可能性。
二、流经叶片914表面的风流中，靠近叶片914表面的气流在受到叶片914的表面的障碍下风速会降低，形成一层边界层，而边界层内的风流风速较低，而边界层之外的风流风速较高，这会导致易于在边界层处产生涡流，而本申请实施例在叶片914形成有出风槽917，出风槽917能够打破边界层的排列，使得边界层内的风流无法形成完整的涡流，从而风流能更均匀地分布在叶片914表面，以降低涡流产生的可能性，从而起到降低噪音的效果。
三、风轮911送出的风流所产生的涡流，在流经蜗舌40时，会被设置于蜗舌40上的多个导流筋42进行分隔，使得尺度较大的涡流会被打散为多个尺度较小的涡流，如此有利于将噪音离散为宽频噪音，降低噪音的影响效果，改善音质。并且，在多个导流筋42的导流作用下，能够减少风流在风轮911轴向方向上的流动，从而能够降低风流在流向出风口15的流动过程中的能量损失。
请结合参阅图7至图9，在一些实施例中，多个叶片914的出风槽917沿风轮911的轴向间隔排布形成有多圈，其中，每一圈的多个出风槽917在风轮911的环向上呈相对设置。
如此，一方面，基于出风均匀性而言，当每一圈的多个出风槽917在风轮911的环向上相对时，在风轮911进行转动下，能使得每一圈内的每一出风槽917的位置与导流筋42的位置所对应，如此，在风轮911进行转动实现送风时，能够使得流经每一圈内的出风槽917所送出的风流的流动方向尽可能一致，从而使得风轮911在其轴向上的送风更为均匀，从而能够减少在轴向上风流之间的扰动，且使得最终流向出风口15且由出风口15流出的风流分布得更为平均，避免风流过于集中在某一区域内，如此，能够提升使用者在使用室内机1时舒适性。
另一方面，当风轮911为塑料材质且在对风轮911进行注塑制造时，可以通过在用于生产叶片914的模具的模腔内凸设有多条间隔排布的凸筋，且每条凸筋可以被配置为环状，如此，通过多条凸筋实现多个叶片914的每一圈出风槽917的成型，而当属于同一圈的多个出风槽917在环向上相对时，对应的凸筋整体是连续且不间隔的筋体，从而使得凸筋的结构设计更为简单，降低模具的生产成本，且能够更便于进行脱模，方便注塑生产。
请参阅图10，而为了进一步减少风轮911送出至蜗舌40的风流所产生的涡流，在一些实施例中，沿风道组件10的前后方向进行投影，出风部916在蜗舌40的投影位于与该出风部916相对的导流槽43之内，且，导流筋42在蜗舌40的投影位于与该导流筋42相对的出风槽917在蜗舌40的投影的区域范围内。如此，尾端与导流筋42相对的叶片914，其出风部916会和与之对应导流槽43完全相对，并且，其出风槽917会和与之对应的导流筋42完全相对，相较于部分相对的形式，本实施例的形式使得出风部916至导流槽43槽底的距离与出风槽917槽底至导流筋42的距离尽可能相等，从而能够进一步实现叶片914送出至蜗舌40的风流在风轮911的轴向上风量尽可能地处处相等，降低风量大的风流流向风量较小的风流的情况发生的可能性，如此，能够进一步减少涡流的产生，便能够更为有效降低噪音的产生可能性。
在一些实施例中，请结合参阅图7至图9，风轮911还可以进一步包括有多个风轮段912和多个分隔板919，多个风轮段912在风轮911的轴向上依次连接，且，每一风轮段912包括多个叶片914，每一分隔板919连接在相邻两个风轮段912的叶片914的片主体915之间，实现通过分隔板919以分隔出多个风轮段912，而位于风轮911相背两端的风轮段912的叶片914的片主体915，其一端与端板918连接，另一端与分隔板919连接。
其中，相邻两个风轮段912的叶片914沿风轮911的环向交替设置。如此，当风轮911进行转动时，可以避免因风流在同一时刻同时通过所有叶片914的风流通道而产生相同的噪音频谱，从而能够避免多个相同的噪音频谱叠加而产生啸叫声，进而能够有效改善风轮911运行时的噪音音质，避免产生啸叫声，起到降低噪音，改善音质的效果。
在一些结构形式中，同一叶片914上的多个出风部916在风轮911的轴向上呈等距分布或者呈不等距分布。可以理解的是，当出风部916呈等距分布或者不等距分布下，实际上出风槽917会与出风部916对应，也相对应呈等距分布或者不等距分布。此外，当风轮911为包括多个风轮段912的形式下，可以是风轮段912的每一叶片914上的多个出风部916在风轮911的轴向上呈等距分布，而当风轮911为非包括多个风轮段912的形式下，可以是沿风轮911的环形间隔排布的多个叶片914中的任一叶片914上的多个出风部916在风轮911的轴向上呈等距分布。
在呈等距分布下的形式下，能够使得风流分别经过每个出风部916和每个出风槽917时，风轮911所送出的风流的流线形状会较为平滑且规律，变化较小，这种流线形状有助于使得风流流动更加平稳，减少涡流，实现降低噪音。
而在呈非等距分布下的形式下，叶片914能够更好地适应不同的环境和风流情况，也即，根据实际的环境和风流情况，来调整具体的相邻两个出风部916之间的距离(同时也能实现调整具体的相邻两个出风槽917之间的距离)，如此，风轮911所送出的风流的流线形状会呈现出所需的变化，也即呈现出一种特定的规律或不规律性，如此，风轮911的适用性能够得到提升，适配范围更广。
请参阅图9，在一些结构形式中，片主体915包括呈相背设置的外表面915a和内表面915b，尾端连接在外表面915a与内表面915b之间。可以理解的是，相邻两个叶片914中，一个叶片914的外表面915a和另一个叶片914的内表面915b之间构设出上述的风流通道，而此处所指的两个表面，两者的关系是相互面向的关系。
其中，出风槽917可以是由外表面915a延伸至尾端，且不贯穿内表面915b设置。该设置形式下，一方面，出风槽917的槽底壁连接在相邻两个出风部916之间，并且会具有一定的厚度，便使得出风槽917的槽底壁将两个出风部916进行连接，如此，使得两个出风部916之间构成为一个整体，实现增强两个出风部916的强度，提高了相邻两个出风部916之间各自的稳定性和抗变形性。另一方面，在实际的注塑制造过程中，在出风槽917不贯穿内表面915b下，可以通过位于模具的模腔内的环形凸筋，一次性在叶片914上形成出一圈的出风槽917，如此，在模具的模腔内无需对一圈的多个出风槽917分别设置多个凸筋来一一对应，从而能够使得模具的结构设计更为简单，降低模具的生产成本，且能够更便于进行脱模，方便注塑生产。
或者，出风槽917也可以是由外表面915a延伸至尾端，且贯穿内表面915b设置。该设置形式下，能够使得相邻两个出风部916之间的区域完全形成为出风槽917，如此，能够进一步保证由相邻两个出风部916之间的区域至导流筋42的距离与出风部916至导流槽43之间的距离相等，从而由片主体915尾端流出的风流，无论是以经过出风部916流出的流动路径或者是经过出风槽917流出的流动路径，在流向蜗舌40的情况下风量都会尽可能地相等，进一步减少风量大的风流流向风量较小的风流的情况发生，如此，能够更为有效减少涡流的产生，进一步降低噪音的产生可能性。
在一些实施例中，出风槽917的槽底壁的厚度在远离尾端的方向上逐渐减小。如此，在实际注塑过程中，通过在模具的模腔内的环形凸筋设置，实现一次性在叶片914上形成出一圈的出风槽917，而在叶片914的横截面形状呈翼型状的情况下，出风槽917的槽底壁的厚度会在远离尾端的方向上逐渐减小，同时，也能够便于进行脱模，方便注塑生产。
请结合参阅图5至图6，在一些实施例中，蜗舌40具有作为弧面的第一蜗舌导流面411，多个导流筋42设于第一蜗舌导流面411上，扩压腔下壳50具有朝向扩压腔12设置的下壳导流面511，其中，蜗舌40导流面与下壳导流面511不共面，导流筋42向扩压腔下壳50延伸的末端与第一蜗舌导流面411相接。如此，在多个导流筋42未延伸至下壳导流面511的情况下，多个导流筋42并不会占用到扩压腔12的空间，从而能够避免扩压腔12供风流流通的空间发生减少，进而能够避免流经扩压腔12的风流的风量减少，保证出风量；另一方面，本实施例的多个导流筋42未延伸至下壳导流面511时，能够减少各个导流筋42的体积，从而能够减少导流筋42的材料用量，降低蜗舌40的生产成本。
进一步地，蜗舌40还具有作为平面的第二蜗舌导流面412，第二蜗舌导流面412与第一蜗舌导流面411相连且在相连处形成相交线，且第二蜗舌导流面412位于第一蜗舌导流面411与下壳导流面511之间并与下壳导流面511共面。
沿多个导流筋42的排布方向(也即左右方向)进行投影，导流槽43的槽底具有槽底型线，导流筋42具有导流筋42型线，导流筋42型线向扩压腔下壳50延伸的末端与槽底型线相交。风轮911所吹出的风流，在流经第一蜗舌导流面411时，经过导流槽43的引导后，会在流向第二蜗舌导流面412后流向扩压腔12。而导流筋42型线的末端在与槽底型线相交，导流筋42的末端并未延伸至扩压腔下壳50的下壳导流面511上。
而为了使得风流在流出导流槽43后，减少风流的能量损耗，本实施例的导流筋42型线向扩压腔下壳50延伸的末端延伸至相交线，如此，相较于导流筋42型线向扩压腔下壳50延伸的末端延伸至相交线之前的形式(也即与槽底型线相交)，风流在流出导流槽43后，便直接流经第二蜗舌导流面412，避免在流出导流槽43后，还需继续流经第一蜗舌导流面411再流向第二蜗舌导流面412，以减少流出过程中风流的损耗。当然，本实施例的导流筋42型线向扩压腔下壳50延伸的末端可以是延伸至相交线之前，本实施例对此不作限定。
在一实施例中，扩压腔12位于换热腔13的一侧，且沿扩压腔12至换热腔13的方向，或者说沿前后方向自后向前地，扩压腔12结束于换热腔13的入口处。扩压腔上壳22远离风机腔上壳21的一端与换热腔上壳23的起始端连接，并不伸入换热腔13内，同样地，扩压腔下壳50远离蜗舌40的一端与接水盘60的起始端连接，并不伸入换热腔13内。由此，扩压腔12的腔顶壁和换热腔13的腔顶壁直接相接，扩压腔12的腔底壁和换热腔13的腔底壁直接相接，而不存在沿上下方向投影时的重合区域。
进一步地，在扩压腔12与换热腔13的连接处，风流的横向流通面积不变或增大。需要说明的是，扩压腔12与换热腔13通过连通口相连通，扩压腔12与换热腔13的连接处具体指沿前后方向，连通口之前至连通口之后的一部分区域。比如，连接处可指扩压腔12中段之后、换热器92之前的这一区域。在一些实施例中，扩压腔12的风流横向流通面积在扩压腔12的结束处最大，换热腔上壳23和接水盘60在上述区域内的部分分别与扩压腔上壳22、扩压腔下壳50在该区域内的部分的延伸方向相同，或者，换热腔上壳23相对于扩压腔上壳22更向上延伸、接水盘60相对于扩压腔下壳50在该区域内的部分更向下延伸，从而使风流的横向流通面积不变或增大。
这样一来，风流在经过在扩压腔12与换热腔13的连接处时，由于扩压腔12与换热腔13是直接相接的，这种设置方式能够减少或避免风流流出扩压腔12时在连通口附近产生涡流或紊流等扰动情况，能够减少压力损失并减少噪音。由于风流在流经扩压腔12与换热腔13的连接处时，风流的流通面积不变或增大，避免因为风流流通面积变小而造成风流的压力损失。通过上述设置，本申请实施例的风道组件10能够有效减少或避免由于扩压腔12至换热腔13这一气流过程中产生涡旋或变截面所带来的压力损失，使风机91所送出的风流的动压更大化地转化为静压，从而有效提高室内机1的出风口15处的静压水平，提升送风距离。而由于减少了气流涡旋等扰动，室内机1在送风时的噪音也将有效减小，送风品质得到提高。
在一些实施例中，沿扩压腔12至换热腔13的方向，在风流流经换热器92之前，扩压腔12与换热腔13的连接处不存在与风流的流动方向呈夹角设置的挡风面。挡风面，指的是风道内与风流的流动方向呈夹角设置的面，可以理解地，这个夹角大于0度，比如为60度，90度等等。试想，若是在风流的流动方向上存在挡风面，风流撞击挡风面便会造成能量损失，不利于风流动压向静压的转化。由此，在本申请的一些实施例中，扩压腔12的内壁大致呈喇叭状扩口设置；而在扩压腔12与换热腔13的连接处，换热腔13的内壁，如换热腔上壳23所限定出的腔顶壁和接水盘60所限定出的腔底壁，相对于连通口呈外扩状设置。这样，风流从扩压腔12流至换热腔13并在穿过换热器92之前这一过程中，并存在因挡风面阻挡而产生的压力损失，进一步提高风流动压转化至静压的转化率。
在一些实施例中，扩压腔上壳22与换热腔上壳23为一体结构，或者扩压腔下壳50以及接水盘60为一体成型构件，亦或者是扩压腔上壳22与换热腔上壳23为一体结构且扩压腔下壳50以及接水盘60为一体成型构件。比如，下壳体30可通过塑胶注塑一体成型，塑胶材料质量较轻，可以降低产品重量，方便运输和安装。本申请实施例中减少了上壳体20和/或下壳体30的零部件的数量，制作工艺简单，适于商业性生产，能够有效提高生产效率和安装效率，并降低成本。
此外，本申请实施例大大降低了多个壳体板件进行拼接的情况，从而减少了连接处出现缝隙的情况，扩压腔12和换热腔13的内壁具有更高的一体性，气流流动过程中的泄漏量大大减少，静压损失也降低，气流传送得更为流畅，从而提高了送风量和换热效率，且减少噪音的产生。
总而言之，扩压腔上壳22与换热腔上壳23为一体成型、扩压腔下壳50与接水盘60一体成型的设计不仅减少了零部件的数量，还降低了装配过程中的复杂度。这种一体成型的结构能够提高整体的稳定性和耐久性。其次，采用一体成型的扩压腔12内壁和换热腔13内壁还可以提供更加均匀的气流分布。相较于使用多个板件拼接而成的壳体结构，一体成型的设计能够消除拼接处的不平整问题，确保气流在风道中的流动更为顺畅，减少了能量损失和压力损耗。此外，由于腔壁是通过一次成型制造而成，不存在拼接处，因此能够有效减少气流泄漏的可能性。这种优化的密封性不仅可以提高系统的工作效率，还有助于防止无关气体或异物进入风道，保护换热腔13的安全和稳定运行。总的来说，本申请实施例基于一体成型的设计理念，通过扩压腔12和换热腔13之间的连接结构进行优化，不仅简化了制造和装配过程，还提升了系统的稳定性、耐久性以及整体的工作效率。
