需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
本发明提供了一种空调器，请参考图1和图2，包括空调器进风口70、空调器出风口80和设置在空调器进风口70和空调器出风口80之间的风道结构，风道结构包括：贯流风叶20；蜗壳蜗舌组件10，贯流风叶20设置在蜗壳蜗舌组件10内；其中，蜗壳蜗舌组件10包括进风口11和出风口12，沿贯流风叶20的延伸方向，进风口11的高度为a，出风口12的高度为b，空调器进风口70的高度为h，空调器出风口80的高度为k，其中，k＜b＜a＜h。
本发明的空调器，沿贯流风叶20的延伸方向，进风口11的高度为a，出风口12的高度为b，空调器进风口70的高度为h，空调器出风口80的高度为k，通过设置有k＜b＜a＜h，从而可以减小风道结构的贯流风道的两端面位置处形成的回流涡，以此避免造成出风不均的现象。其中，空调器包括空调器进风口70、空调器出风口80和设置在空调器进风口70和空调器出风口80之间的风道结构，风道结构包括蜗壳蜗舌组件10和贯流风叶20，贯流风叶20设置在蜗壳蜗舌组件10内，蜗壳蜗舌组件10包括进风口11和出风口12。本发明的空调器可以减小风道结构的贯流风道的两端面位置处形成的回流涡，以此避免造成出风不均的现象，解决了现有技术中的空调器的风道结构出风不均的问题。
在本实施例中，蜗壳蜗舌组件10具有贯流风道，贯流风道具有进风口11和出风口12。
优选地，6mm≤a-b≤15mm。
在本实施例中，对于风道结构，进风风阻变大，风道结构的流通负载阻力变大。出风风阻变大，风道结构流通负载阻力变小。因此当出风口12高度小于进风口11高度时，有利于保证风道结构的进出风的连续性和顺畅程度。在6mm≤a-b≤15mm时，既可以保证较佳的进出风顺畅程度，又不至于对贯流风叶20造成较大的遮挡高度，进而保证贯流风叶20的有效工作高度。

为了保证贯流风叶20正常运行，贯流风叶20与第一挡圈50间隙配合。
优选地，贯流风叶20与第一挡圈50之间的间隙为c，其中，5mm≤c≤10mm。
在本实施例中，贯流风叶20两端的流量和流速较低，压力梯度较大，控制间隙较小，可以减少这种压力梯度的剧烈变化，改善因压力变化产生的喘振现象。但间隙太小，对风叶的动平衡、风道精度等要求很高，实际很难达到而导致风机运转时与风道内壁产生碰撞或摩擦的问题，故，在本实施例中，当5mm≤c≤10mm时，可以有效地减少贯流风叶20两端的压力梯度的剧烈变化。
针对第一挡圈50的具体结构，如图3所示，第一挡圈50包括：第一进风挡圈段51，第一进风挡圈段51设置在上端盖30靠近进风口11的一侧；第一出风挡圈段52，第一出风挡圈段52设置在上端盖30靠近出风口12的一侧；其中，第一进风挡圈段51的外端面距贯流风叶20的第一端的端面的距离为e，第一出风挡圈段52的外端面距贯流风叶20的第一端的端面的距离为d，e＜d。
在本实施例中，第一挡圈50由第一进风挡圈段51和第一出风挡圈段52组成，其中，第一进风挡圈段51设置在上端盖30靠近进风口11的一侧，第一出风挡圈段52设置在上端盖30靠近出风口12的一侧。
为了保证进风口11的高度为大于出风口12的高度，优选地，第一进风挡圈段51的外端面距贯流风叶20的第一端的端面的距离为e，第一出风挡圈段52的外端面距贯流风叶20的第一端的端面的距离为d，其中，e＜d。
优选地，3mm≤d-e≤8mm。
在本实施例中，通过设置3mm≤d-e≤8mm，既可以保证较佳的进出风顺畅程度，又不至于对贯流风叶20造成较大的遮挡高度，进而保证贯流风叶20的有效工作高度。
相应地，风道结构还包括：下端盖40，下端盖40设置在蜗壳蜗舌组件10的第二端；第二挡圈60，第二挡圈60设置在下端盖40上，贯流风叶20的第二端的至少部分穿设在第二挡圈60内；其中，第一挡圈50和第二挡圈60相对设置，进风口11和出风口12位于第一挡圈50和第二挡圈60之间。
优选地，贯流风叶20与第二挡圈60间隙配合。
优选地，贯流风叶20与第二挡圈60之间的间隙为s，其中，5mm≤s≤10mm。
针对第二挡圈60的具体结构，如图2和图4所示，第二挡圈60包括：第二进风挡圈段61，第二进风挡圈段61设置在下端盖40靠近进风口11的一侧；第二出风挡圈段62，第二出风挡圈段62设置在下端盖40靠近出风口12的一侧；第二进风挡圈段61的外端面距贯流风叶20的第二端的端面的距离为f，第二出风挡圈段62的外端面距贯流风叶20的第二端的端面的距离为g，f＜g。
在本实施例中，第一进风挡圈段51和第二进风挡圈段61之间为进风口11，第一出风挡圈段52和第二出风挡圈段62之间为出风口12。
优选地，3mm≤g-f≤8mm。
优选地，空调器包括空调器进风口70和空调器出风口80，风道结构位于空调器进风口70和空调器出风口80之间；其中，沿贯流风叶20的延伸方向，空调器进风口70的高度大于进风口11的高度，和/或出风口12的高度大于空调器出风口80的高度。
优选地，沿贯流风叶20的延伸方向，空调器进风口70的高度为h，空调器出风口80的高度为k，其中，6mm≤h-a≤15mm，和/或，6mm≤b-k≤15mm。
在本实施例中，整体风道沿流动方向满足风道高度逐步变小的变化趋势。空调器进风口70、进风口11、出风口12和空调器出风口80为逐渐收窄的结构设计。
空调器还包括换热器90，换热器90设置在空调器进风口70和贯流风道的进风口11之间。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
本发明的空调器，沿贯流风叶20的延伸方向，进风口11的高度为a，出风口12的高度为b，空调器进风口70的高度为h，空调器出风口80的高度为k，通过设置有k＜b＜a＜h，从而可以减小风道结构的贯流风道的两端面位置处形成的回流涡，以此避免造成出风不均的现象。其中，空调器包括空调器进风口70、空调器出风口80和设置在空调器进风口70和空调器出风口80之间的风道结构，风道结构包括蜗壳蜗舌组件10和贯流风叶20，贯流风叶20设置在蜗壳蜗舌组件10内，蜗壳蜗舌组件10包括进风口11和出风口12。本发明的空调器可以减小风道结构的贯流风道的两端面位置处形成的回流涡，以此避免造成出风不均的现象，解决了现有技术中的空调器的风道结构出风不均的问题。
贯流风道系统两端为相对低压区，贯流风叶在工作过程中，容易在两端面位置处形成回流涡，造成出风不均的现象，容易引起噪声问题，另外在空调应用制热送风时，由于存在回流现象，导致两端面卷吸出风口外空气，从而导致出风口两端面的温度明显低于风口其余位置的温度，存在出风不均的问题。
本发明的空调器，整体风道沿流动方向满足风道高度逐步变小的变化趋势。空调器进风口70、进风口11、出风口12和空调器出风口80为逐渐收窄的结构设计，解决了贯流风道出风端面出风不均、出风温度不均的问题。
