暖通系统涵盖的设备种类众多，例如包括空调、多联机、热泵、热水器等设备，而暖通系统包括室内机和室外机。室内机特别是天花机，在制冷模式下，其中的蒸发器会产生冷凝水，该冷凝水滴落到电气元件上会使其受损，并且冷凝水向天花机外滴落还会影响用户体验。
相关技术中，空调室内机通过设置有接水盘与换热器直接接触，来承接换热器产生的冷凝水，这样换热器为冷源时，接水盘与换热器的接触传热会导致接水盘外侧有凝露产生，该凝露水无法汇集到接水盘中，会直接滴在空调室内机的内部，从而影响内部的各功能部件例如电控组件等的正常工作。
为解决上述问题，请参阅图1至3，本申请的第一方面提出了一种空调室内机1，在本申请实施例中，该空调室内机1包括机壳10、主接水盘20、换热器30以及副接水盘40。
机壳10包括相连接的外壳11和底盘12，机壳10可以是由不锈钢、铝合金等强度较高的材料制成，以更好保护设置于机壳10内部的各功能部件。主接水盘20与外壳11连接并位于外壳11的下方，底盘12连接于外壳11与主接水盘20之间，主接水盘20位于机壳10的底部。外壳11和底盘12可以是可拆卸形式连接，例如是螺接、卡接等，方便对内部的各部件进行维护，当然，二者也可以是一体成型结构，以提高机壳10的整体强度，本申请对此不作限制。进一步的，本申请机壳10还可以包括面板(未示出)，面板连接在外壳11的底部，并位于主接水盘20的下方，在空调室内机为天花机的情况下，在室内安装环境中，天花板上设置有安装口，面板封盖在该安装口处。其中面板和机壳10配合限定出风道，并且面板上设置有连通风道的回风口13(参图1)和送风口。
换热器30位于机壳10内且位于风道中，其中，换热器30可以是单折形式的板式换热器，也可以是多折板式换热器换热器30。在其为单折板式换热器的情况下，换热器30在主接水盘20的上方倾斜设置，且本申请换热器30倾斜设置于回风口13的上方，且换热器30在水平方向上的投影至少部分位于回风口13内。具体而言，参加图3，换热器30可以是与水平方向的夹角为θ，夹角θ的范围可选择为0°＜θ≤45°。在此，换热器30与水平方向的夹角θ越小，空调室内机1的整机厚度可以相应的减小，但是，换热器30在回风口13上的投影面积也将越来越大，即换热器30上的冷凝水也越容易从回风口13处滴出。因此，θ的范围可选择为15°≤θ≤45°。
可以理解的是，当换热器30为弧形或其他形式设置时，换热器30也可以为非倾斜设置，即换热器30可以水平设置于主接水盘20的上方，以适应其不同的结构形式，本申请对此不作限制。
当空调室内机1处于制冷模式或除湿模式时，换热器30为蒸发器，此时蒸发器表面会产生冷凝水，主接水盘20和副接水盘40能够对冷凝水进行收集并排出，从而避免冷凝水空调室内机1的内部的各功能部件，例如电控组件等造成损坏。
需要说明的是，为能够更好承接换热器30上由于重力作用顺流滴落的冷凝水，副接水盘40设于换热器30朝向机壳10的底部的一侧，并位于主接水盘20和换热器30之间。其中，换热器30包括配置为对流进风道的气流进行换热的换热主体32，副接水盘40包括接水槽体41，接水槽体41配置为承接自换热主体32下坠的冷凝水。也即，换热器30在水平面的投影落入主接水盘20和副接水盘40在水平面上的投影区域内，在换热器30表面上形成的冷凝水一部分顺着换热器30的主体结构的表面流动至换热器30的底端部，进入到主接水盘20中，而由于换热器30为倾斜设置，则另一部分冷凝水在重力的因素下，会直接下坠，该部分的冷凝水流入副接水盘40的接水槽体41内，其中，副接水盘40中的冷凝水可以排入主接水盘20内，也可以是直接通过管道排出至空调室内机1之外，本申请对此不作限制。
以及，主接水盘20背离换热器30的一侧表面还贴附有保温组件(未示出)，该保温组件可以是海绵、绒布等吸水性、隔热性较好的材质，如此，保温组件的包覆使得主接水盘20内部积蓄的冷凝水不会与外部空气进行良好热交换，而在主接水盘20的外侧产生凝露。也即，本申请主接水盘20和副接水盘40的配合形式，保证换热器30的冷凝水均能够被有效收集，并且能够防止冷凝水溢出导致空调室内机1产生漏电等安全隐患。进一步地，本申请还在接水槽体41与换热主体32之间设置有隔热层50，隔热层50可以有效隔离换热主体32与接水槽体41之间的热传递。
请再次参照图2，换热器30包括两相对设置的边板31，换热主体32连接在两边板31之间。换热主体32由换热翅片以及换热管构成，换热管在长度方向上穿设于换热翅片，换热翅片可以扩大外部空气与换热管中的冷媒之间的接触面积，从而提高外部空气与冷媒之间的热交换效率。也即，本申请在接水槽体41与换热主体32之间设置有隔热层50，可以理解为，在换热翅片的外表面与接水槽体41之间设置有隔热层50。
在一实施例中，接水槽体41与换热主体32之间存在有间隙，其中，间隙形成为隔热层50。也即，接水槽体41与换热主体32之间可以通过该间隙实现二者间的空气隔热。接水槽体41与换热主体32直接接触，会导致接水槽体41背离换热主体32的一侧表面遇冷产生凝露，该凝露水无法汇集于接水槽体41内，而是会直接顺延接水槽体41的外表面滴落至空调室内机1内，从而影响内部的各功能部件例如电控组件等的正常工作，而通过接水槽体41与换热主体32之间存在的间隙，可以减少上述凝露水的产生，从而进一步保证空调室内机1的工作稳定性。
为了进一步降低接水槽体41背离换热主体32的一侧表面遇冷产生凝露的情况，在一实施例中，还包括隔热材料层(未示出)，隔热材料层填充于上述的间隙，可选择的，隔热材料层的材质为海绵，如此可以在有效隔绝接水槽体41与换热主体32之间的接触的同时，还能防止在工作时由于机震，且二者之间存在间隙而造成的磕碰，减少对副接水盘40和换热器30的维护问题。当然的，隔热材料层也可以选择为其他材料，例如是绒布等，本申请对此不作限制。
请参照图5至图7，本申请接水槽体41包括多个接水壳体，每一接水壳体形成凹槽结构，凹槽结构开口朝向换热主体32，多个接水壳体在换热器30的宽度方向上间隔设置，并且每一接水壳体在换热器30的长度方向上延伸，则相邻的两个接水壳体之间形成有过风通道412，从而可以尽可能降低对由回风口13流入的气流的阻挡。进一步的，为了提升整个副接水盘40的结构强度，副接水盘40还包括连接槽体411，连接槽体411连接于接水槽体41上，其中连接槽体411可以连接在接水槽体41的中部位置，其中，连接槽体411可以将接水槽体41中的冷凝水导向主接水盘20，并且接水槽体41也可以将接水槽体41中的多个接水壳体连接成一体，从而提升结构强度。
此外，如图5和图6所示，副接水盘40还包括与连接槽体411连接的支撑部42，支撑部42抵接于换热主体32朝向机壳10的底部的一侧，以使得接水槽体41与换热主体32之间形成间隙。支撑部42可以在换热器30的宽度方向上为副接水盘40提供支撑力，同时引导换热器30上产生的冷凝水。
副接水盘40还包括引水槽体43，引水槽体43连接在接水槽体41的端部，引水槽体43配置为将接水槽体41中的冷凝水汇聚至主接水盘20，引水槽体43与接水槽体41可以为一体成型结构，以使的冷凝水在引水槽体43和接水槽体41之间的流动顺畅，减少漏水，提高排水效率。
具体的，引水槽体43包括槽主体431以及连接于槽主体431的第一连接部432和第二连接部433，槽主体431与所述接水槽体41连接。其中，第一连接部432与机壳10可拆卸连接，第二连接部433与其所对应的一边板31可拆卸连接。
请参照图4，示例性示出的，第一连接部432与底盘12的其中一者设置有卡扣121，另一者形成有卡孔4321，卡扣121与卡孔4321配合卡接。因副接水盘40设置于底盘12的下方，则当第一连接部432形成为卡孔4321形式，而与底盘12上的卡扣121配合卡接时，副接水盘40即可由该可拆卸形式吊装于底盘12上。可以理解的，第一连接部432与机壳10的可拆卸形式还可以是例如通过二者的材料形变构成。
可以理解的是，第二连接部433可以仅设置于副接水盘40的长度方向上的其中一侧，以对副接水盘40与边板31的连接起定位作用的同时，节省生产材料；或者，第一连接部432与第二连接部433还可以设置于副接水盘40的长度方向上的两端，由此，第一连接部432与底盘12可拆卸连接后，第二连接部433与边板31插接，以此将副接水盘40固定于机壳10的内部，实现副接水盘40的快速安装以及定位，以及，副接水盘40的可拆卸连接还可方便对其进行清理、维护以及更换，节省维护成本。
另外，槽主体431的底部抵接在主接水盘20上，当第一连接部432与机壳10可拆卸连接，第二连接部433与边板31可拆卸连接后，副接水盘40即吊装于机壳10内，而副接水盘40的槽主体431此时可抵接于主接水盘20上，以对副接水盘40下部进行支撑，实现对副接水盘40的三方位支撑及限位，更好保证副接水盘40的安装稳定性，并且槽主体431的底部形成有的冷凝水，也可以通过与主接水盘20的抵接而流入主接水盘20内，如此也能够更有效的避免冷凝水滴落至两接水盘的外部。
在一实施例中，为能够更有效快捷的将主接水盘20内收集到的冷凝水排出空调室内机1外，空调室内机1还包括有水泵，水泵与主接水盘20连通，则可以通过水泵将主接水盘20内收集的冷凝水排出空调室内机1外，提升了主接水盘20的排水效率。可以理解的是，主接水盘20也可以采用重力排水的方式，以此实现将主接水盘20收集的冷凝水排出空调室内机1外，当然，还可以同时采用上述两种方式进行排水，从而能够更高效的将主接水盘20内的冷凝水快速排出空调室内机1外，如此可以进一步提高了主接水盘20的排水效率，本申请对此不作限制。
请参照图8至图11，在一些实施例中，机壳10还可以包括面板，面板与外壳11连接，外壳11内具有空腔，面板和外壳11配合限定出风道10a(如图14所示)，也即该空腔的一部分也形成风道10a，且面板上设置有连通风道10a的回风口和送风口。换热器30以及主接水盘20均位于风道10a内，且主接水盘20位于换热器30的下方，其中面板位于主接水盘20的下方。
其中，机壳10上设置有第一限位结构14，主接水盘20上设置有第二限位结构21，第一限位结构14与换热器30的上端卡持配合，第二限位结构21与换热器30的底端抵接配合，且第一限位结构14与第二限位结构21配合以将换热器30固定于风道10a中，从而减少换热器30在风道10a中发生移动。
需要说明的是，在换热器30进行安装时，先将换热器30的上端卡接或插接到机壳10的第一限位结构14中，然后通过安装主接水盘20，并使得主接水盘20上的第二限位结构21与换热器30的底端抵接，由此完成换热器30的固定安装。本申请实施例通过在机壳10上设置第一限位结构14，并且在主接水盘20上设置第二限位结构21，使得换热器30可以在第一限位结构14以及第二限位结构21的限位作用下固定于机壳10的风道10a中，从而简化空调室内机1中换热器30的安装方式及安装步骤，同时，机壳10内形成有风道10a，风道10a中会有气流的流动，换热器30在风道10a中也会受到气流作用，本实施例可以提高换热器30的稳定性，且减少换热器30在气流的负压作用下产生晃动。
另外，在相关技术中，换热器30的边板上通常需要设置伸出换热器30本体的固定耳，以实现换热器30可以用螺钉进行固定，但是因为固定耳的存在，会导致换热器30的生产无法采用连体切工艺，从而存在换热器30生产效率低下问题。而在本申请实施例中，换热器30通过机壳10以及主接水盘20的限位，来实现换热器30的安装固定，本实施例通过改变换热器30的安装方式，以使得换热器30的生产物料以及装配操作减少，由此提高换热器30的可制造性，同时，取消对换热器30上固定耳的设置，还可以避免固定耳在换热器30的周转运输过程中发生碰伤变形的问题。
在本申请一些实施例中，在换热器30沿其长度方向L1的相对两侧均设置有第一限位结构14。
具体地，第一限位结构14与换热器30的上端卡持配合，第一限位结构14可以沿换热器30的长度方向L1设置于换热器30的相对两侧，也就是说，第一限位结构14可以与换热器30上方的相对两端卡持配合，以对换热器30的上端进行固定。相对于第一限位结构14沿换热器30的长度方向L1延伸设置而言，本实施例仅在换热器30的相对两侧设置第一限位结构14，一方面可以减少第一限位结构14的生产用料，另一方面可以减少第一限位结构14对风道10a中气流的遮挡，使得换热器30在风道10a中可以交换更多气流。其中，如图8所示，机壳10的外形大致为长方体，换热器30呈长条状设置于机壳10内，即换热器30的长度方向L1与机壳10的长度方向L1相同。
请参见图11，在本申请一些实施例中，换热器30包括互相连接的换热主体32和边板31，换热主体32和/或边板31与第一限位结构14卡持配合，换热主体32和/或边板31与第二限位结构21抵接配合。
可以理解的是，第一限位结构14可以卡持固定换热器30的换热主体32，也可以卡持固定换热器30的边板31，也可以同时卡持固定换热器30的换热主体32和边板31；同理，第二限位结构21可以与换热器30的换热主体32抵接固定，也可以与换热器30的边板31抵接固定，也可以与换热器30的换热主体32和边板31同时抵接固定，可以根据实际情况进行选择设置。
其中，边板31的制作材料可用塑料或金属等，保证边板31具有一定的强度，可选地，边板31通过注塑开模制作而成，或者，边板31用金属板拉伸冲压而成。
进一步地，请参见图9至图13，在本申请一些实施例中，第一限位结构14具有容纳槽141，换热主体32和/或边板31卡持于容纳槽141中。
示例性的，换热主体32的上端卡接于容纳槽141中，容纳槽141的各个槽壁与换热主体32上端的顶壁以及侧壁均接触，并沿换热主体32的宽度方向L2，对换热主体32进行限位，以防止换热器30在换热主体32宽度方向L2上发生位移。同理，边板31的上端卡接于容纳槽141中，容纳槽141的各个槽壁与边板31上端的顶壁以及侧壁均接触，并沿换热主体32宽度方向L2，对边板31进行限位，以防止换热器30在换热主体32宽度方向L2上发生位移。其中，若换热器30竖直设置，则换热主体32的宽度方向L2是指换热器30的高度，若换热器30倾斜设置，则换热主体32的宽度方向L2是指换热器30的上端到换热器30下端的倾斜连线的延伸方向。
或者，在本申请一些实施例中，第一限位结构14具有限位孔，边板31上设置有定位件，定位件插接于限位孔中，以对换热器30整体进行限位。第一限位结构14可以在换热主体32的宽度方向L2抵接边板31的顶端，定位件插接到限位孔中，还可以在换热主体32的长度方向L1限制换热器30的移动，从而进一步的对换热器30进行限位。其中，本实施例对定位柱的制备材料以及形状均不做具体限定，例如，定位柱可以采用强度较大的金属或塑料材质制备，且定位柱的形状可以为方柱体或圆柱体等。
请继续参见图9和图10，在本申请一些实施例中，机壳10上还设置有第三限位结构15，在换热器30的长度方向L1上，换热器30的相对两侧均设有第三限位结构15，且当换热器30在安装到机壳10上时，第三限位结构15与换热器30沿换热器30的长度方向L1的相对两侧均接触，从而在换热器30的长度方向L1上为换热器30提供限位作用，防止换热器30在换热器30的长度方向L1上发生位移。
其中，换热器30的边板31可以位于换热主体32靠近主接水盘20的一侧，也就是说，换热主体32靠近机壳10的一侧可以与第三限位结构15进行接触限位；或者，第三限位结构15也可以与边板31进行接触限位，此处不做具体限定。
请参见图11至图13，在本申请一些实施例中，第二限位结构21包括第一凸起部211，第一凸起部211沿换热主体32的长度方向L1延伸(如图2所示)，且第一凸起部211与换热主体32的底端抵接，以为换热器30的底部提供支撑，限制换热器30在重力作用下滑动。易于理解的是，第一限位结构14到第一凸起部211的距离与换热器30的宽度相同，由此可以提高换热器30安装到第一限位结构14与第一凸起部20之间的可靠性。
请参见图11、图14和图15，在本申请一些实施例中，换热器30在主接水盘20的上方倾斜设置，也即，换热器30的上端与下端的连线与竖向呈夹角设置。
具体的，换热器30设置在机壳10的风道10a内，换热器30的上端被机壳10上的第一限位结构14限位，主接水盘20位于换热器30的下方，换热器30的下端被主接水盘20上的第二限位结构21限位，由于换热器30是倾斜设置，则换热器30具有朝向主接水盘20的运动趋势，在本申请实施例中，第二限位结构21还包括第二凸起部212，第二凸起部212与换热主体32和/或边板31朝向主接水盘20的一侧抵接，也即第二凸起部212与换热器30的倾斜侧面抵接，从而使得第二凸起部212为换热器30提供支撑，从而使得换热器30的设置更稳定，且第二凸起部212沿换热主体32的长度方向L1设置于第一凸起部211的相对两侧，以使得换热器30的相对两侧均可以受到支撑作用。
在本申请一些实施例中，机壳10、第一限位结构14、第一凸起部211以及第二凸起部212共同形成安装腔(图中未示出)，换热器30设置于安装腔内，其中，安装腔的内侧壁是由机壳10、第一限位结构14、第一凸起部211以及第二凸起部212的侧壁形成，安装腔的内侧壁与换热器30的周侧接触，也就是说，安装腔的形状与换热器的形状适配，由此提高换热器30在安装腔中的安装可靠性。
其中，如图13和图15所示，第一凸起部211具有配置为与换热主体32的底端抵接的第一表面213，第二凸起部212具有配置为与边板31朝向主接水盘20的侧面抵接的第二表面214，第一表面213与第二表面214限定出一个放置空间，以便于为换热器30提供限位。
为了进一步提升换热器30的稳定性，在一些实施例中，请参照图14至图18，机壳10与换热器30之间设置有止挡部61，止挡部61与换热器30背离主接水盘20的一侧抵接。可以理解的是，止挡部61位于换热器30背离主接水盘20的一侧，第二凸起部212位于换热器30靠近主接水盘20的一侧，且止挡部61以及第二凸起部212均与换热器30的侧面抵接，也就是说，止挡部61以及第二凸起部212相对设置在换热器30的两侧，同时，第一凸起部211设置在换热器30的底端，由此止挡部61、第一凸起部211以及第二凸起部212共同合围形成夹持空间，换热器30的底端位于该夹持空间内，即使风道10a内有气流对换热器30产生负压作用，换热器30的位置也可以更稳定，减少换热器30发生晃动。
其中，如图16所示，机壳10内还设置有风轮62，风轮62位于换热器30的一侧，当风轮62设置为一个时，风轮62的一侧设置电机，另一侧设置止挡部61；当风轮62设置有多个时，相邻两个风轮62之间通过联轴器连接，止挡部61设置在联轴器上。
在本申请一些实施例中，机壳10包括位于换热器30沿其长度方向L1相对两侧的侧板15(如图8所示)，侧板15覆盖副接水盘40的边缘部分，也就是说，有部分侧板15可以压住副接水盘40靠近侧板15的边缘部分，以对副接水盘40形成限位，降低副接水盘40发生松动的可能性。
其中，空调室内机1在组装时，可以先将换热器30的上端卡持到机壳10的第一限位结构14中，然后将副接水盘40的底端安装到机壳10上，且将副接水盘40上的第二连接部433与边板31上的通孔插接，此时副接水盘40靠近侧板15的边缘部分被侧板15压住，随后将主接水盘20上的第二限位件对准换热器30的底端，且将主接水盘20与侧板15进行连接固定，由此完成空调室内机1的组装。
本申请还提出一种暖通系统，该暖通系统包括如上所述的空调室内机1，且该暖通系统的具体结构参照上述实施例，由于本暖通系统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有益效果，在此不再一一赘述。其中，上述暖通系统包括且不限于空调、多联机、热泵、热水器等设备。
本实施例的附图中相同或相似的标号对应相同或相似的部件；在本申请的描述中，需要理解的是，若有术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此附图中描述位置关系的用语仅配置为示例性说明，不能理解为对本申请的限制，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
