空调器一般包括空调外机和空调内机。空调外机内设有压缩机和冷凝器，压缩机将气态的制冷剂压缩为高温高压的气态制冷剂，气态制冷剂在冷凝器散热后成为常温高压的液态制冷剂，最后通过毛细管输送到空调内机。空调内机内设有蒸发器和贯流风扇，液态制冷剂到达蒸发器后空间突然增大，发生汽化变成气态低温的制冷剂，从而可吸收大量的热量；贯流风扇引导室内的空气从蒸发器中经过，空气在蒸发器中换热后从空调内机吹出至环境中，以降低环境的温度。

具体实施方式
如图1-图4所示，在相关技术的方案中，空调内机包括机壳110、蒸发器120、风道130、贯流风扇140和接水盘，蒸发器120和风道130相对设置在机壳110的内部，贯流风扇140设置在蒸发器120和风道130之间，接水盘位于风道130的下方。蒸发器120的两侧与风道130固定连接，其中，蒸发器120的右侧设有右管板121，右管板121与风道130 之间通过右连接板150相连接。具体的，沿空调内机的轴向方向，风道130上设有两个第一安装座131，右连接板150的第一侧设有两个与第一安装座131一一对应的第一固定孔151，风道130与右连接板150通过螺钉等紧固件实现连接固定；沿空调内机的轴向方向，右管板121上设有三个第二安装座1211，右连接板150的第二侧设有三个与第二安装座1211一一对应的第二固定孔152，风道130与右连接板150通过螺钉等紧固件实现连接固定。此外在右连接板150与风道130之间还设有密封垫160，以防止漏风。
但是，采用上述相关技术的方案，蒸发器120的右侧与风道130之间的连接结构较为复杂，影响了空调内机的组装效率。具体体现在：蒸发器120与风道130之间需要通过右连接板150实现连接，因此需要先将蒸发器120与右连接板150连接后，再将风道130与右连接板150实现连接，组装效率慢；并且在制造过程中需要单独设计右连接板150的模具，提高了整体成本。此外，右连接板150与风道130和右管板121之间均是通过螺钉连接的，螺钉连接本身的连接效率也较慢。
有鉴于此，本申请旨在提供一种空调内机及空调器，以简化蒸发器的右侧与风道之间的连接结构，提高空调内机的组装效率。
为使本申请实施例的目的、技术方案和优点更加清楚，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，所描述的实施例是本申请一部分实施例，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。
实施例一
图5是本申请一实施例提供的空调内机的结构简图；图6是图5的俯视图；图7是图6中A部的局部放大图；图8是图5的爆炸视图。
请参照图5-图8，本实施例提供一种空调内机，包括机壳210、蒸发器220、风道和贯流风扇240，机壳210包括沿空调内机的轴向相对设置的上固定座211和下固定座212，机壳210的表面设有进风口和出 风口，蒸发器220设置在机壳210内靠近进风口的一侧，风道设置在机壳210内靠近出风口的一侧，风道包括左风道231和右风道232，左风道231和右风道232之间形成有间隙，出风口与间隙相连通，贯流风扇240设置在蒸发器220和风道之间；蒸发器220的上下两端分别与上固定座211和下固定座212固定连接，蒸发器220的两侧分别与左风道231和右风道232相连接，其中，蒸发器220的右侧设有右管板221，右管板221连接在右风道232上。
具体的，本实施例中机壳210、蒸发器220、风道和贯流风扇240均是沿空调内机的轴向设置的。机壳210可以呈圆柱状或棱柱状，具体可根据实际需要进行选择；机壳210的材料可选用金属或塑料，本实施例对此不做限定。在机壳210的表面设有相对的进风口和出风口，空气从进风口进入机壳210内并从出风口吹出。机壳210还包括沿空调内机的轴向相对设置的上固定座211和下固定座212，上固定座211和下固定座212用于支撑并固定蒸发器220等零件，具体的固定方式可选用卡接、螺纹连接等。
蒸发器220设置在机壳210内靠近进风口的一侧，室内空气从进风口进入后被引导至蒸发器220内，从而实现热量的交换。风道设置在机壳210内靠近出风口的一侧，风道包括左风道231和右风道232，左风道231和右风道232之间形成有间隙，出风口与间隙相连通，空气从该间隙内流到出风口处。贯流风扇240设置在蒸发器220和风道之间，用于引导空气加速流动，提升换气效率。
本实施例中，蒸发器220的上下两端分别与上固定座211和下固定座212固定连接，蒸发器220的两侧分别与左风道231和右风道232相连接，其中，蒸发器220的左侧与左风道231之间可以采用螺纹连接、卡接等连接形式进行连接固定；蒸发器220的右侧设有右管板221，右管板221直接连接在右风道232上，具体连接方式可根据需要进行选择。这样，蒸发器220可以通过与上固定座211和下固定座212的连接结构实现固定防止蒸发器220发生倾倒等现象，保证蒸发器220在机壳210内的正常工作；蒸发器220与左风道231和右风道232之间连接后可以 保证内部风道的严密性，保证空调内机在运行过程中不漏风。
本实施例通过将蒸发器220的右侧直接连接在右风道232上，从而省去了相关技术中的右连接板等零件，这样不仅简化了组装过程，有利于提高空调内机的组装效率，还能够省去制造右连接板的模具，有利于降低成本。
在一种可能的实施方式中，如图7所示，本实施例的右管板221包括本体2211、第一折板2212和第二折板2213。本体2211设置在蒸发器220的右侧面，本体2211上穿设有多根冷媒管道。第一折板2212连接本体2211的第一端且朝向背离蒸发器220的一侧延伸。第二折板2213连接本体2211的第二端且朝向蒸发器220的一侧延伸。
右风道232朝向右管板221的一侧设有连接部233，第一折板2212与连接部233相连接，从而实现蒸发器220与右风道232的直接相连。第一折板2212与连接部233的具体连接结构可以采用以下两种形式。
请继续参照图7，在一种可能的实施方式中，第一折板2212可以抵接在连接部233上。
具体的，本实施例的连接部233呈柱状(可以呈圆柱状或棱柱状，本实施例以棱柱状为例进行说明)。连接部233包括相对平行设置的第一平面2331和第二平面2332，第一平面2331和第二平面2332均与右风道232相连接；连接部233背离右风道232的一侧还设有相连接的连接面2333和过渡面2334(也可以不设过渡面2334，使连接面2333的两端分别与第一平面2331和第二平面2332相连接)，连接面2333连接第一平面2331，过渡面2334连接第二平面2332。连接面2333与第一折板2212平行，第一折板2212抵接在连接面2333上。通过将连接面2333设置成与第一折板2212平行的结构，可以提高第一折板2212抵接在连接面2333上的稳定性，防止连接结构实效。
进一步地，第一折板2212与连接部233之间还设有密封垫250，密封垫250可以提高连接面2333与第一折板2212之间的密封性能，从而防止发生漏气。密封垫250可以套设在连接部233上，在图7所示的平面内，密封垫250的形状可以与连接部233的形状相似，从而更好的实 现与连接部233之间的连接。密封垫250可选用海绵或泡棉等材料，密封垫250与连接部233及第一折板2212之间可采用粘接连接的方式实现固定。
更进一步地，本实施例的机壳210上还设有连接座213，连接座213设置在机壳210的内侧。连接座213上设有支撑板214，支撑板214背离连接座213的一侧设有抵接件215，抵接件215的一端与支撑板214相连接，抵接件215的另一端抵接在第二折板2213上。其中支撑板214可选为金属板，抵接件215可以为弹性件，抵接件215设置在第二折板2213和支撑板214之间时可以处于压缩状态，从而给第二折板2213施加一个抵接力，有利于保持第一折板2212与连接部233之间的抵接连接关系。
在另一种可能的实施方式中，本实施例的第一折板2212还可以卡接在连接部233上。采用卡接连接的方式也能够实现简化组装过程，提高空调内机的组装效率的目的。
具体的，可以在第一折板2212上设有卡爪，在连接部233上设有卡槽，将卡爪卡接固定在卡槽内以实现第一折板2212与连接部233之间的卡接。
请继续参照图6，本实施例中蒸发器220包括左段2201、右段2202和弯曲段2203，弯曲段2203设置在左段2201和右段2202之间，右段2202背离弯曲段2203的一侧设有右管板221，左段2201朝向贯流风扇240的一侧以及右段2202朝向贯流风扇240的一侧均为平面，弯曲段2203朝向贯流风扇240的一侧为曲面。相较于相关技术中的蒸发器，本实施例通过上述设置省去了一个曲面段和一个平面段，整个蒸发器220的体积有了较大的降低，从而可以节省材料，降低整体成本。
综上所述，本实施例通过将蒸发器220的右侧直接连接在右风道232上，从而省去了相关技术中的右连接板等零件，这样不仅简化了组装过程，有利于提高空调内机的组装效率，还能够省去制造右连接板的模具，有利于降低成本。
实施例二
本实施例提供一种空调器，包括相互连接的空调内机和空调外机，其中，空调内机采用如上述实施例一的空调内机。
本实施例的空调器主要包括压缩机、冷凝器、蒸发器、四通阀和毛细管组件等，其中，压缩机、冷凝器和四通阀设置在空调外机内，蒸发器设置在空调内机内，毛细管组件连接蒸发器和冷凝器，毛细管组件中设有流动的制冷剂。
空调器的制冷过程为：压缩机将气态的制冷剂压缩为高温高压的气态制冷剂，然后送到冷凝器散热后成为常温高压的液态制冷剂，液态制冷剂通过毛细管组件进入蒸发器，由于制冷剂从毛细管到达蒸发器后空间突然增大，制冷剂受到的压力减小，液态的制冷剂就会汽化，变成气态低温的制冷剂，从而吸收大量的热量，蒸发器就会变冷，空调内机的贯流风扇引导室内的空气从蒸发器中吹过，从而使空调内机吹出冷风。空调器的制热过程与上述制冷过程的原理相同，只不过利用四通阀使制冷剂在冷凝器与蒸发器的流动方向与制冷时相反，从而实现制热的目的。
本实施例的空调器由于采用了上述实施例一的空调内机，因此省去了相关技术中的右连接板等零件，这样不仅简化了组装过程，有利于提高空调内机的组装效率，还能够省去制造右连接板的模具，有利于降低成本。
