本实施例提供的一种空调器通过使用压缩机、冷凝器、膨胀阀和蒸发器来执行空调器的制冷制热循环。制冷制热循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向已被调节和热交换的空气供应冷媒介质。
压缩机压缩形成高温高压状态的冷媒气体并排出压缩后的冷媒气体。所排出的冷媒气体流入冷凝器。冷凝器将压缩后的冷媒冷凝成液相，并且热量通过冷凝过程释放到周围环境。
膨胀阀使在冷凝器中冷凝的高温高压状态的液相冷媒膨胀为低温低压的液相冷媒。蒸发器蒸发在膨胀阀中膨胀的冷媒，并使处于低温低压状态的冷媒气体返回到压缩机。蒸发器可以通过利用冷媒的蒸发的潜热与待冷却的材料进行热交换来实现制冷效果。在整个循环中，空调器可以调节室内空间的温度。
空调器的室外机是指制冷循环的包括压缩机、室外换热器和室外风机的部分，空调器的室内机包括室内换热器和室内风机的部分，并且节流装置(如毛细管或电子膨胀阀)可以提供在室内机或室外机中。
室内换热器和室外换热器用作冷凝器或蒸发器。当室内换热器用作冷凝器时，空调器执行制热模式，当室内换热器用作蒸发器时，空调器执行制冷 模式。
其中，室内换热器和室外换热器转换作为冷凝器或蒸发器的方式，一般采用四通阀，具体参考常规空调器的设置，在此不做赘述。
空调器的制冷工作原理是：压缩机工作使室内换热器(在室内机中，此时为蒸发器)内处于超低压状态，室内换热器内的液态冷媒迅速蒸发吸收热量，室内风机吹出的风经过室内换热器盘管降温后变为冷风吹到室内，蒸发汽化后的冷媒经压缩机加压后，在室外换热器(在室外机中，此时为冷凝器)中的高压环境下凝结为液态，释放出热量，通过室外风机，将热量散发到大气中，如此循环就达到了制冷效果。
空调器的制热工作原理是：气态冷媒被压缩机加压，成为高温高压气体，进入室内换热器(此时为冷凝器)，冷凝液化放热，成为液体，同时将室内空气加热，从而达到提高室内温度的目的。液体冷媒经节流装置减压，进入室外换热器(此时为蒸发器)，蒸发气化吸热，成为气体，同时吸取室外空气的热量(室外空气变得更冷)，成为气态冷媒，再次进入压缩机开始下一个循环。
参照图1-图7所示，根据本申请一些实施例，空调室内机，其包括：
外壳1，外壳1上设置有进风口101和出风口102；出风口102包括第一子出风口1021和第二子出风口1022，外壳1包括上壳体12和下壳体13，下壳体13设置在上壳体12上，第一子出风口1021和进风口101设置在下壳体13的底面，第二子出风口1022设置在下壳体13的侧壁；
室内换热器2，室内换热器2设置在外壳1中；
室内风机3，室内风机3设置在外壳1中；
具体而言，外壳1采用上壳体12和下壳体13组装而成，室内换热器2和室内风机3设置在外壳1中，而为了增大送风范围，则在下壳体13的底面上配置第一子出风口1021，第一子出风口1021能够直接朝下输送气流，进而满足冬季向室内的下方吹热风，以减少热气上升导致房间下部空间温度过低。
下壳体13的侧壁上配置有第二子出风口1022，第二子出风口1022能够横向输出气流，进而满足夏季向室内输送冷风以将冷风吹向横向房间的底部，冷风利用冷气下沉，以使得房间全方位的制冷。
在本申请的一些实施例中，为了方便吸入到外壳1中的空气与室内换热 器2充分的热交换，对于室内换热器2而言，其采用U型结构，室内换热器2半包围在室内风机3的外侧，第一子出风口1021和第二子出风口1022布置在室内换热器2的外侧区域，进风口101布置在室内换热器2的内侧区域。
具体的，采用U型结构的室内换热器2，能够充分利用外壳1内的空间布置足够大的换热面，进而提高空气的热交换效率。同时，室内风机3可以采用离心风机并被室内换热器2半包围住，室内风机3沿轴线吸入的空气将直接垂直外侧的室内换热器2，更有利于提高出风口102的出风风速。
第一子出风口1021和第二子出风口1022均分布在室内换热器2的外侧，对于第一子出风口1021而言，第一子出风口1021所在的地面与室内换热器2相对布置，从室内换热器2换热后的空气能够直接从第二子出风口1022输出；对于第二子出风口1022而言，第二子出风口1022所在的侧壁与室内换热器2相对布置，从室内换热器2换热后的空气能够直接从第二子出风口1022输出。
在本申请一些实施例中，可以在下壳体13的前侧壁设置有第二子出风口1022，而在下壳体13的两端部的底面位置分别设置有第一子出风口1021。由于在安装时，所述空调室内机的后部一般靠近墙壁安装，这样，从下壳体13的前侧壁的第二子出风口1022输出的横向气流能够最大限度的覆盖整个房间；而下壳体13底面上的两个第一子出风口1021则能够从两端部朝向房间送风，进一步的覆盖外壳1的底部区域。
在本申请一些实施例中，为了在使用时方便的将冷凝水排出至外部，空调室内机还包括水泵6，所述水泵布置在所述外壳靠近前侧壁的位置，所述水泵位于所述室内换热器和所述室内风机之间。
具体的，所述水泵根据需要可以安装在上壳体12或下壳体13上，以安装在上壳体12为例进行说明。在使用过程中，尤其是夏季制冷时，所述室内换热器产生的冷凝水收集在所述室内换热器配置的接水盘中，然后，通过所述水泵将冷凝水排出。
而通过将所述水泵布置在靠近所述外壳的前侧壁位置，所述室内风机吹出的风越过所述水泵从所述室内换热器输出。通过所述室内换热器遮挡所述水泵，以降低所述水泵吸水产生的噪音外泄。在一些实施方式中，所述水泵布置在所述室内换热器的角部位置，这样，所述室内风机吹向所述水泵的气流受所述室内换热器的角部区域缓冲，以减少风噪，提高用户体验性。
在本申请另一些实施例中，所述下壳体的下表面还设置有检修口103，所述检修口上设置有可拆卸地检修盖104；所述上壳体上设置有控制器7，所述控制器与所述检修口相对布置。
具体的，所述控制器则与空调室内机的电器部件连接，以控制相关电器部件的运行，如控制器7控制室内风机3、水泵6等电器部件运行。而为了方便后期维修，则在所述下壳体的下表面还设置有检修口103，通过打开检修盖104便可以对控制器7进行维修操作，以提高维修便利性。
在另一些实施例中，为了方便吊挂安装，外壳1的两侧分别设置有多个挂杆10。空调室内机还包括吊装支架4，吊装支架4的两侧分别设置有多个挂钩41；其中，挂杆10用于插在对应的挂钩41中。
具体而言，在将空调室内机在房间内进行安装过程中，先将吊装支架4通过膨胀螺栓42固定安装在房间的顶面1000；然后，将外壳1举起并使得挂杆10插入到对应的挂钩41中，以通过挂钩41和挂杆10配合，实现外壳1吊装在屋顶上。
通过将吊装支架固定在房间的顶部，以满足外置式安装的要求，吊装支架上配置有挂钩，同时，在外壳上配置挂杆，在安装时，挂杆则直接插入到挂钩中，以实现将外壳吊挂在房间的顶部，这样，一方面使得空调室内机不占用室内的有效空间，另一方面使得空调室内机满足已装修好的房间的使用要求，增大了空调室内机的使用范围。
在本申请的一些实施例中，为了在挂杆10挂在挂钩41上后，确保外壳1能够牢固可靠地的固定在吊装支架4上，则挂杆10的自由端部设置有螺纹部(未标记)，所述螺纹部上螺纹连接有螺母100。
具体的，在安装过程中，挂杆10插入到对应的挂钩41上后，挂杆10的自由端部将伸出至挂钩41的外侧，然后，将螺母100螺纹连接到挂杆10的自由端部，以通过拧紧螺母100对挂杆10进行锁紧，进而提高安装可靠性。
在本申请的一些实施例中，对于挂钩41的具体结构形式，可以有多种方式，在一些实施方式中，可以在吊装支架4上形成一体结构的挂钩41，具体的，吊装支架4的两侧分别设置有朝下延伸的悬挂板43，悬挂板43的一侧边设置有缺口结构，所述缺口结构形成挂钩41。
在加工吊装支架4的过程中，通过弯折边缘以形成悬挂板43，然后，采用冲孔等机加工方式，在悬挂板43上形成缺口结构以构成挂钩41。挂钩 41一体形成在吊装支架4上，进而使得挂钩41与吊装支架4的连接强度更高。
而对于吊装支架4而言，在某些实施例中，为了减少吊装支架4所占用的高度空间，吊装支架4整体呈板状结构，并同时配置有凹凸结构或加强筋结构以增强吊装支架4的结构强度。
在本申请的一些实施例中，所述缺口结构的入口处设置有朝上突出的限位部44。
具体的，在将挂杆10插入到挂钩41的过程中，挂杆10从缺口结构的入口滑入，并越过限位部44以完成安装。挂杆10在限位部44的作用下，将减少出现挂杆10从挂钩41中脱离出的现象发生，进而提高安装可靠性。
在一些实施例中，为了方便操作人员安装，所述缺口结构的入口为喇叭口。具体的，所述缺口结构的入口采用喇叭口的形式，使得挂杆10能够方便的从较大开口处滑入到所述缺口结构中，以使得挂杆10能够准确方便的挂在挂钩41上。
在本申请的一些实施例中，还包括装饰板5，装饰板5设置在外壳1上并遮盖住对应位置处的挂杆10。
具体的，由于挂杆10在挂在挂钩41上后，挂杆10的自由端部外露在挂钩41的外侧，同时，螺母100也外露在挂钩41的外侧。而通过在外壳1上配置装饰板5，利用装饰板5来遮挡挂杆10和螺母100，以优化整体外观效果。
在一些实施例中，为了方便快捷的安装装饰板5，装饰板5卡装在外壳1上。
具体的，在实际安装过程中，将挂杆10安装在挂钩41上并螺纹连接上螺母100后，便可以采用卡装的方式将装饰板5快捷的装配到外壳1上。
其中，可以在外壳1上设置有卡槽123，装饰板5上设置有卡爪51，卡爪51卡在卡槽123中。
另外，为了方便准确的定位，外壳1上还设置有定位孔122，装饰板5上还设置有定位柱52，定位柱52插在定位孔122中。
具体的，外壳1上设置有多个卡槽123，同样的，装饰板5上设置有相对应数量的卡爪51。在装配装饰板5时，先将定位柱52插入到定位孔122中，然后，将装饰板5推向外壳1，在定位柱52的导向作用下，使得卡爪 51准确的卡在卡槽123中。
在本申请的一些实施例中，外壳1包括钣金顶板11和壳体，钣金顶板11上设置有挂杆10，所述壳体上设置有进风口101和出风口102，室内换热器2和室内风机3设置在钣金顶板11，所述壳体设置在钣金顶板11上并遮盖住室内换热器2和室内风机3。
具体的，为了提高空调室内机的整体稳定性，对于室内换热器2和室内风机3而言，则固定安装在钣金顶板11上，钣金顶板11具有足够的结构强度来满足承载室内换热器2和室内风机3等部件的要求，而壳体则主要用于装饰和进出风。
在本申请的一些实施例中，为了提高第二子出风口1022的出风量，上壳体12的前侧壁设置有出风缺口121，下壳体13的前侧壁上设置有第二子出风口1022，第二子出风口1022与出风缺口121相对布置。
具体的，由于室内换热器2和风机均安装在外壳1的钣金顶板11上，从室内换热器2输出的气流经由出风缺口121能够直接从第二子出风口1022输出，以减少风阻提高送风量。
在本申请的一些实施例中，外壳1还包括进风格栅14，进风格栅14设置在下壳体13的底面并遮盖住进风口101。
具体的，进风格栅14设置在下壳体13的底面以遮挡住进风口101，进而提升外观效果，而进风格栅14自身结构，又能够满足进风口101顺畅进风的要求。
在本申请的另一些实施例中，下壳体13的侧壁包围在上壳体12的侧壁外部。
具体的，对于上壳体12和下壳体13在组装过程中，下壳体13将从上壳体12的下部包围在上壳体12的外部，这样，用户在房间内向上方看整机的整体外观效果更佳。
而对于上壳体12和下壳体13之间的组装方式，可以采用卡装、螺钉连接等方式，在此不做限制和赘述。
在本申请的一些实施例中，为了减少外观上外露螺钉，优选采用卡装的方式，具体的，下壳体13的侧壁上设置有导向凸起131和卡扣132，上壳体12的侧壁上设置有导向槽124和限位孔125，导向凸起131插在导向槽124中，卡扣132卡在限位孔125中。
具体的，在组装过程中，上壳体12设置在钣金顶板11上，两者固定的方式可以采用螺钉等常规连接方式。而下壳体13则通过导向凸起131与导向槽124相互配合进行导向安装，最终，使得卡扣132卡装在限位孔125中。
在卡扣132与限位孔125的作用下，可以确保上壳体12与下壳体13之间牢固的连接，同时，由于下壳体13的包裹在上壳体12的外部，使得整体外观无需螺钉显露。
在本申请的一些实施例中，由于室内换热器2需要进行冷媒管路的连接，而室内风机3需要进行电缆的连接，为了方便向外引线并实现隐藏布线的要求，则可以在上壳体12上设置有用于布设管线的通道126，通道126靠近在上壳体12的后侧壁。
具体的，在安装过程中，冷媒管路和线缆从上壳体12引出并经由通道126进行布线，冷媒管路和线缆位于通道126中，以减少管线的外露，一方面优化整体外观效果，另一方还可以确保管线安全可靠的布线，以提高后期使用安全性。
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。
