具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，在本申请中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请提出一种空调室内机100，包括壳体10，壳体10包括底盘组件11和面框组件13，底盘组件11连接面框组件13并围合形成风道，面框组件13开设有连通风道的进风口131和出风口133，风道内设有风轮17，以及围设于风轮17外侧的蒸发器15；
蒸发器15包括后蒸发段155，后蒸发段155设置在靠近所述底盘组件11的一侧，即设置在靠近壳体10的后侧，后蒸发段155于上下方向形成夹角γ，γ至少是25°且不超过50°。
本申请实施例中的空调室内机100主要为壁挂式空调室内机，风轮17可选为贯流风轮17。该壁挂式空调室内机100于安装完成时即具有使用状态，该使用状态下，机壳10的后侧通过安装板安装于安装载体，该安装载体通常为墙壁。定义垂直于该安装表面的方向为前后方向，并定义在同一水平面内与该前后方向相垂直的方向为左右方向，垂直于水平面的方向定义为上下方向，通常情况下，壁挂式空调室内机于该左右方向上的尺寸最大。可以理解地，在该壁挂式空调室内机100具有非使用状态时，前后方向、上下方向以及左右方向对其进行的限定均根据使用状态进行相应的调整。
本申请技术方案中，在风轮17的驱动下外界空气由进风口1311进入风道内，并于风道内的蒸发器15进行热交换，接着经过经风轮17和出风口1313吹出，该过程中蒸发器15的后蒸发段155设置的位置尤为重要，该后蒸发段155于上下方向的夹角γ越大，则后蒸发段155的迎风面积越大，换热效率越高；另外，后蒸发段155于上下方向的夹角γ越小，蒸发器15上形成的冷凝水的排除效率越高。因此，将蒸发器15的后蒸发段155与上下方向的夹角γ取值范围限定于：γ至少是25°且不超过50°，具体可以取值为25°、30°、40°或50°，或者25°~50°之间的任意值，从而能提高蒸发器15的换热效率以及排水的可靠性，能有效避免空调器产生吹水现象。
若γ的取值小于25°时，该后蒸发段155处迎风面积过小，换热效率太低；若γ的取值小于50°时，后蒸发段155上产生的冷凝水不易排出，从而使得蒸发器上细菌滋生，不利于使用者的身体健康。
进一步参见图1，后蒸发段155靠近底盘组件11。
蒸发器15的后蒸发段155靠近底盘组件11设置，从而能提高蒸发器15靠近底盘组件11处的空气换热效率，且使得蒸发器15靠近底盘组件11处产生的冷凝水排除效率高。
本申请实施例中，后蒸发段155靠近进风口131的一侧朝向远离底盘组件11方向倾斜设置。该后蒸发段155在排水效果好的同时迎风面积大、换热效率高。
本申请实施例中，底盘组件11包括底盘111和后蜗舌113，后蜗舌113一端于出风口133处连接底盘111并且另一端朝向后蒸发段155和风轮17之间的区域延伸，后蜗舌113靠近后蒸发段155的外壁面与上下方向形成夹角θ，θ至少是25°且不超过50°。
空气由进风口1311进入风道内，在流经蒸发器15的过程中存在一定的阻力，蒸发器15相当于对气流做了一次整流，空气流经蒸发器15后速度和方向都发生了改变，而流经蒸发器15后蒸发段155的空气不仅受到后蒸发段155位置的影响还受到后蜗舌113的影响，因此，后蒸发段155与上下方向的夹角γ以及后蜗舌113靠近后蒸发段155的外壁面与上下方向形成夹角θ的取值，对后蜗舌113附近区域气流第一次流经风轮17叶片时的角度和速度起到决定性的作用，参见附图3，后蜗舌113附近区域Ⅰ，气流第一次流经风轮17叶片的区域Ⅱ，气流第二次流经风轮17叶片的区域Ⅲ。该实施例中，后蒸发段155与上下方向的夹角γ限定在25°~50°的范围之内，具体可以取值为25°、30°、40°或50°，或者25°~50°之间的任意值。后蜗舌113靠近蒸发器15的外壁面与上下方向的夹角θ需要与后蒸发段的位置相匹配，若θ小于25°或大于50°均会使得后蒸发段的换热效率降低，对空气流动阻力增大。将后蜗舌113靠近蒸发器15的外壁面与上下方向的夹角θ限定在25°~50°的范围之内，使后蜗舌113与后蒸发段155布局角度相匹配，从而使得流经后蒸发段155的气流受到的阻力较小，并能更好的趋向于风轮17。
结合图2，在空调室内机100的横截面上，风轮17的中心至后蜗舌113最近点的连线与风轮17的中心至后蜗舌113的自由端的连线形成的夹角为β，β至少是10°且不超过30°。
具体地，定义后蜗舌113距离风轮17最近的点为A点，定义后蜗舌113的自由端的端点为B点，定义风轮17的中心为O点，∠AOB为β。
经实验数据表明，β的取值大小对后蜗舌113附近进入风轮17气流的稳定性起主导作用。该实施例中，将β限定在10°~30°之间，具体可以为10°、20°、30°，或者10°~30°之间的任意取值，该取值范围内，后蜗舌113附近进入风轮17的气流更加稳定，出风效果更好。该β值取值过大或过小，均会造成风轮出风效率降低。
定义风轮17的外径为d，风轮17与后蜗舌113的最小间距为δ，δ至少是0.035d，且不超过0.065d。参见图2，A点至风轮17的距离为δ，δ值可以为0.035d、0.04d、0.045d、0.05d、0.06d、0.065d。当δ值超过0.065d时，因风轮17与后蜗舌113之间的间隙过大会使得气流泄露严重，导致风量衰减。当δ值小于0.035d时，因风轮15与后蜗舌113之间的间隙过小而导致噪音值偏高，严重时会产生啸叫声。本实施例中，后蜗舌113距风轮17的最小距离为δ，δ在该取值范围内，能够确保后蜗舌113附近区域气流第一次流经风轮17叶片时的流通效率，减小涡流区的大小和强度，从而确保气流经过风轮17时的高效率和低噪声。
本申请实施例中，风轮17的中心至后蜗舌113最近点的连线与水平面所形成的夹角为α，α至少是20°，且不超过55°。在上述定义的横截面上，定义过风轮17中心点O点的水平面与底盘111的交点为D点，∠DOA为α，α的取值为20°、30°、40°、50°、55°。该δ的取值以及α的取值，共同确保后蜗舌113附近区域气流第一次流经风轮17叶片时的流通效率，更进一步减小涡流区的大小和强度，从而确保贯流风道的高效率和低噪声。α小于20°或大于55°时，会造成涡流区增大，强度升高等不良影响。
进一步地，α大于β。参见图2，该实施例中，定义A点和D点之间的一点C点，∠AOB=∠AOC，定义B点至C点部分为后蜗舌113部分。
本申请实施例中，后蒸发段155与上下方向的夹角γ，能改善后蜗舌113附近区域气流第一次穿越叶片时的角度和速度，提升气流在叶片间的流通效率，从而改善风轮17叶片对气流的做功效率，降低气流损失，提升风道效率，降低噪声。
参见图1，本申请实施例中，蒸发器15还包括中蒸发段153和前蒸发段151，后蒸发段155和中蒸发段153的一端于风轮17的上方相连接，后蒸发段155背离所述中蒸发段153的一端朝向风轮17的后侧方向延伸，中蒸发段153背离后蒸发段155的一端朝向风轮17的前侧方向延伸，前蒸发段151连接中蒸发段153背离后蒸发段155的一端，并位于风轮17的前侧。
该实施例中，前蒸发段151、中蒸发段153和后蒸发段155共同组成的蒸发器15围设于风轮17，前蒸发段151沿上下方向设置，以使得该前蒸发段151排水效率高，中蒸发段153在前后方向上位于后蒸发段155与前蒸发段151之间，并与上下方向形成夹角，使得蒸发器15整体换热效率高，且排水效率好。
进一步地，面框组件13包括面框131和前面板133，前面框131罩盖与底盘组件11，并于蒸发器15的上方开设进风口1311，前面板133连接面框131，并位于壳体10的前侧，与底盘组件11相对设置。该实施例中，蒸发器15与风轮17之间还设有电辅热，在应用该空调室内机100的空调器进行制热过程中，将电辅热开启，能够进一步提高空调器的制热效率。
本申请还提出一种空调器，该空调器包括空调室外机和空调室内机100，该空调室内机100的具体结构参照上述实施例，由于本空调器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有效果，在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
