下面参照图1至图11描述根据本申请一些实施例所述的空调室内机1和空调器。
实施例一：
根据本申请的第一方面的一个实施例，本申请的第一方面提出了一种空调室内机1，包括：壳体10和设置在壳体10内的换热器12。
具体地，换热器12包括沿第一方向呈波浪形设置的多个第一换热段120，相邻两个第一换热段120之间形成有换热区，沿第一方向，换热器12依次设置有第一换热区122和第二换热区124；从壳体10的顶部至壳体10的底部的方向，第一换热区122沿第一方向的宽度逐渐增大，第二换热区124沿第一方向的宽度逐渐减小；其中，壳体10沿第一方向间隔的两个第一侧壁102上开设有第一入风口14，壳体10沿第二方向的顶壁上和/或壳体10沿第三方向间隔的两个第二侧壁104上开设有与第二换热区124对应的第二入风口16，壳体10沿第二方向的底壁上开设有与第一换热区122对应的第一出风口18；第一方向、第二方向和第三方向互相垂直，第二方向为重力方向。
本申请提供的空调室内机1，包括壳体10和设置在壳体10内的换热器12，其中，沿第二方向，第一出风口18设于壳体10的底壁，当空调室内机1在进行自然对流制冷时，气流经过换热器12后，变为用于制冷的冷空气，冷空气密度比空气更大，在重力的作用下冷空气换热后流向下方的第一出风口18，最终由第一出风口18进入室内进行制冷，冷空气流出后壳体10内形成负压，进而继续吸引空气从第一入风口14和第二入风口16流入壳体10，形成自然对流空气循环。通过自然对流的形式为室内的空气进行换热，整个换热过程无需风机20工作，进而在保证良好的换热能力的情况下，避免了风机20工作产生的噪音。
具体地，如图1和图2所示，第一方向为壳体10的宽度方向，第二方向为重力方向，也即壳体10的高度方向，第三方向为壳体10的长度方向。 第一出风口18设置在壳体10的底壁，也即沿重力方向，第一出风口18设置在壳体10的底板106上。沿重力方向，壳体10位于下方的壁面也即壳体10的底壁，也就是底板106的壁面；沿重力方向，壳体10位于上方的壁面也即壳体10的顶壁。
其中，换热器12包括沿第一方向设置的多个第一换热段120，多个第一换热段120呈波浪形，这样的设置方式在壳体10的体积确定的情况下，提高了换热效率，进而提升了空调室内机1的换热能力。相邻两个第一换热段120之间形成有换热区，且沿第一方向，换热器12依次设置有第一换热区122和第二换热区124，第一换热区122的宽度由壳体10的顶部至底部的逐渐增大，第二换热区124的宽度由壳体10的顶部至底部逐渐减小，也就是，第一换热区122由下至上逐渐缩小，因此第一换热段120上的冷凝水会沿翅片1200流下，避免冷凝水直接滴落，便于冷凝水的收集。
具体地，形成第一换热区122的相邻两个第一换热段120的上端部相互交错设置，使得相邻两个第一换热段120的顶部实现搭接，进而避免空气由未经过换热器12换热后进入第一换热区122。
可以理解的是，第一出风口18与第一换热区122对应设置，也就是空气由第一入风口14、第二入风口16进入壳体10后，与第一换热段120换热后进入第一换热区122，然后由第一出风口18流出。第二入风口16与第二换热区124对应设置，也就是空气由第二入风口16进入第二换热区124，然后与形成第二换热区124的第一换热段120换热后进入第一换热区122，然后由第一出风口18流出。
进一步地，如图2所示，第二入风口16设于两个第二侧壁104上；向垂直于第三方向的参考面进行投影，第二入风口16的投影位于第二换热区124的投影之内；和/或如图6所示，第二入风口16设于壳体10的顶壁上，向垂直于第二方向的参考面进行投影，第二入风口16的投影位于形成第一换热区122的两个第一换热段120的下端部的投影之间。
在该实施例中，对于第二入风口16设置在两个第二侧壁104上的情况，在垂直于第三方向的参考面进行投影，第二入风口16的投影位于第二换热区124的投影之内，使得形成第二换热区124的第一换热段120，能够与 由第二入风口16流入壳体10的空气换热，提高了空调器的制冷效率。对于第二入风口16设置在壳体10的顶壁上的情况，向垂直于第二方向的参考面进行投影，第二入风口16的投影位于第二换热区124的投影之内，使得由壳体10顶部的第二入风口16进入壳体10的空气，能够与形成第二换热区124的第一换热段120换热后由第一出风口18流出，也就是，通过第二入风口16的设置，保证了沿第一方向位于内部的第一换热段120也能实现换热，进而提升了空调器的换热能力。
其中，对于第二入风口16同时设置在壳体10的顶壁和两个第二侧壁104上时，增大了进风面积，进而提升了空调室内机1的出风量。
进一步地，如图2所示，形成第一换热区122的两个第一换热段120的上端部与下端部连线之间具有夹角β，夹角β小于180°，进一步地，夹角β小于90°，从而便于冷凝水的收集，在有限的空间内增大了空气与换热器12的换热面积，进而提升了空调室内机1的输出能力，提高了空调室内机1的换热效率，以尽快的达到用户的设定温度，进而提升用户使用的舒适性。
实施例二：
如图2和图3所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：空调室内机1还包括第二出风口24，沿第二方向，第二出风口24设于壳体10的底壁；其中，形成第二换热区124的相邻两个第一换热段120的下端部之间具有间隙，第二出风口24经过间隙与第二换热区124连通。
在该实施例中，空调室内机1还包括第二出风口24，第二出风口24设置在壳体10的底壁，并且第二出风口24经过间隙与第二换热区124连通，在空调室内机1实现自然对流出风时，由第一入风口14和第二入风口16进入壳体10的空气与换热器12换热后由第一出风口18流出，使得壳体10内形成负压，从而第二入风口16充当进风口，使得室内回风能够由第二入风口16经相邻第一换热段120之间的间隙进入第二换热区124，进而与第一换热段120换热后由第一出风口18流出，也就是，第二出风口24的设置，能够在自然对流换热时提高空调室内机1的进风量，进而提高 空调室内机1的换热效率。
实施例三：
如图6和图7所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：空调室内机1还包括风机20，风机20包括进口202和出口204，风机20设于第二换热区124内；风门22，风门22可开合地与第二入风口16连接；其中，在风机20开启的状态下，风门22关闭第二入风口16，由第一入风口14和第一出风口18流入壳体10的空气流入进口202，然后由出口204流向第二出风口24。
在该实施例中，空调室内机1还包括风机20和风门22，风机20设置在第二换热区124，风门22可开合地与第二入风口16连接，也就是，通过风门22的设置，使得第二入风口16能够实现开关，通过风机20的设置，能够实现主动送风，进而提升空调室内机1的制冷量。
如图7所示，当风机20开启时，第一入风口14、两个第一出风口18作为进风口与风机20的进口202连通，大大提升了进风量，第二出风口24作为出风口与风机20的出口204连通，将换热后的气流由第二出风口24排出至室内，以对室内环境制冷或者制热。风机20开启状态下，可通过风门22关闭第二入风口16，以避免从第二入风口16进入的气流未经换热器12换热排出而降低换热效率。
其中，风机20开启时，沿第一方向，一部分气流由靠近风机20进口202的第一侧壁102上的第一入风口14，和壳体10底壁上的第一出风口18被风机20抽吸至风机20内，进而由出口204排至第二出风口24；同时，一部分气流由远离风机20进口202的第一侧壁102对应的第一入风口14、壳体10底壁的另一个第一出风口18被卷吸至壳体10内，进而由第二出风口24排出壳体10，从而通过风机20的主动送风提供更大风量，实现了更大制冷量的效果。
进一步地，如图3和图6所示，当风机20关闭时，第一入风口14和第二入风口16作为进风口，气流由第一入风口14和第二入风口16经换热器12换热后由第一出风口18流出，使得腔体内形成负压，从而第二出风口24充当进风口，也即此时气流也能够通过第二出风口24流入壳体10， 并分别经形成第二换热区124的两个第一换热段120换热后由第一出风口18流出，增大了进风量和制冷量，提升了制冷效果。风机20关闭状态下，可开启第二入风口16，使得气流能够由第二入风口16进入的壳体10，与形成第二换热区124的第一换热段120换热，增加了自然对流的制冷量。
在另一个实施例中，如图4所示，风机20开启时，也可以不关闭第二入风口16，气流由第二入风口16进入风机20，然后与由第一入风口14、第一出风口18进入壳体10并与换热器12换热后的气流混合后由第二出风口24流出，提升了空调器的出风量，降低了风阻。
进一步地，在该实施例中，如图3和图4所示，壳体10同一侧的任一第二入风口16包括第一子风口160和第二子风口162，在垂直于第三方向的投影面上，壳体10同一侧的第一子风口160和第二子风口162分别位于风机20的两侧。如图4所示，当风机20开启时，一部分气流由第二子风口162经风机20抽吸后进入风机20，一部分气流在负压的作用下由第一子风口160进入壳体10，进而这两部分气流与由第一入风口14、第一出风口18进入壳体10并与换热器12换热后的气流共同由第二出风口24排出。
进一步地，如图1所示，风机20的数量为两个，两个风机20沿第三方向分布。
在该实施例中，风机20的数量为两个，两个风机20沿第三方向分布，从而在第三方向上提升了出风量。
进一步地，如图1所示，空调室内机1还包括镂空支架26，镂空支架26位于第二换热区124内，风机20设于镂空支架26上。
在该实施例中，空调室内机1还包括镂空支架26，风机20设置在镂空支架26上，对风机20起到支撑的作用，同时，镂空支架26能够供气流通过，降低了气流的流通阻力，提升了出风速度和出风量。
具体地，在关闭风机20时，部分气流还能够由第二出风口24经镂空支架26流向形成第二换热区124的第一换热段120，并经与第一换热段120换热后流向第一出风口18。
进一步地，风机20的顶端与壳体10的顶壁相连接，提升了风机20的可靠性。
进一步地，风机20包括贯流风机。
在该实施例中，风机20包括贯流风机，贯流风机具有风量大、噪声低、出风气流稳定等优点，从而使用贯流风机能够提升空调室内机1的出风量，且降低空调室内机1运行时的噪音。
实施例四：
根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：在垂直于第三方向的截面中，位于第一换热区122两侧的第一换热段120呈轴对称设置，轴对称设置的对称轴沿第二方向延伸。
在该实施例中，形成第一换热区122的两个第一换热段120对称设置，从而使得两个第一换热段120能够在有限的空间内增大了换热面积，提升换热能力，也即形成较大的第一换热区122，进而使得空气完全经过换热器12换热后再由第一出风口18流出。
当然，相邻的两个第一换热段120可以不完全对称，也即允许具有一定的偏差。例如，相邻的两个第一换热段120中的一个第一换热段120相对第二方向的倾角，与另一个第一换热段120相对第二方向的倾角相差不超过5°。
进一步地，相邻的两个第一换热段120沿第二方向的对称轴对称设置，从而能够在有限的空间内增大了换热面积，在开启风机20时，一侧主动制冷一侧被引射制冷，提升了换热能力及换热器12利用效率。
实施例五：
如图2所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：第一换热区122的数量为两组，沿第一方向，两组第一换热区122间隔设置，第一换热区122和第二换热区124交错分布；其中，第一出风口18的数量为两组，第一出风口18与第一换热区122一一对应设置，空调室内机1的第二出风口24位于两组第一出风口18之间。
在该实施例中，第二换热区124的数量为两组，两组第二换热区124间隔设置，且第一换热区122和第二换热区124交错设置，第一出风口18与第一换热区122一一对应设置，且第二出风口24设置在两组第一出风口18之间，该种设置方式，在保证了空调器的换热效果的同时，减小了空调室内机1沿第 一方向的尺寸。
进一步地，在垂直于第三方向的截面中，第一换热区122的截面呈倒置的V形，第二换热区124的截面呈V形。
在该实施例中，倒置的V形和V形是指大致的V形，或类似V形。一方面，倒置的V形结构，使得形成第一换热区122的两个第一换热段120中的至少一者相对于第二方向倾斜设置，在有限的壳体10空间内增加了换热面积；另一方面，倒置的V形结构，便于冷凝水的收集，避免冷凝水滴落在壳体10的底壁上或直接滴落在室内的地面上。同样地，第二换热区124的截面呈V形，便于放置风机20，以及便于形成第二换热区124的两个第一换热段120上的冷凝水的收集。
其中，在一个实施例中，如图8所示，沿第一方向，位于最外侧的第一换热段120的上端部与下端部之间的连线相对于第二方向倾斜设置。
在该实施例中，位于最外侧的第一换热段120的上端部与下端部之间的连线相对于第二方向倾斜设置，也就是，第一换热段120倾斜设置，进而在增加换热面积的同时，还便于第一换热段120上冷凝水的收集。
其中，在另一个实施例中，如图9所示，沿第一方向上，位于最外侧的第一换热段120的上端部与下端部之间的连线相对于第二方向平行设置。
在该实施例中，位于最外侧的第一换热段120的上端部与下端部之间的连线，相对于第二方向平行设置，从而使得第一方向的进风与第一换热段120完全换热后排出，提升了换热效果，同时也缩短了壳体10在第一方向上的宽度。
实施例六：
如图8和图9所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：换热器12还包括：第二换热段28和第三换热段30，第二换热段28和第三换热段30设于第二换热区124内；其中，第二换热段28与第三换热段30之间形成第三换热区32，从壳体10的顶部至壳体10的底部的方向，第三换热区32沿第二方向的宽度逐渐增大。
在该实施例中，换热器12还包括第二换热段28和第三换热段30，第二换热段28和第三换热段30均设置在第二换热区124内，并形成第三换热区 32，增加了第二换热区124内的换热面积，进而提升了制冷或制热能力。其中，第三换热区32的宽度由壳体10顶壁至壳体10底壁逐渐增大，从而第二换热段28和第三换热段30形成的第三换热区32对气流起到向下引导的作用，便于自然对流时气流的流出，提升自然对流能力。
进一步地，在垂直于第三方向的截面中，第三换热区32呈倒置的V形。
实施例七：
如图5所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：在垂直于第三方向的截面中，形成第一换热区122的两个第一换热段120中，一个第一换热段120的上端部与下端部的连线，相对于第二方向形成的夹角为第一夹角α1，另一个第一换热段120的上端部与下端部的连线相对于第二方向形成的夹角为第二夹角θ1；第二夹角θ1大于或等于第一夹角α1的一半与10°之差，且小于或等于第一夹角α1的一半与10°之和。
在该实施例中，在形成第一换热区122的两个第一换热段120中，一个第一换热段120靠近风机20设置，另一个第一换热段120远离风机20设置，因此，第二夹角θ1越大，则靠近风机20的第一换热段120距离风机20越远，相应地，第二入风口16的面积也会越大，当第二入风口16未关闭时，风机20抽吸到的未经换热的室内回风就越多，经换热器12换热后的气流越少，进而导致第二入风口16未关闭时开启风机20时的主动强风效果下降；当第二夹角θ1为0°时，靠近风机20的第一换热段120竖直设置，在风机20开启时的制冷性能较好，但此种形态下自然对流效果较差，因此，将第二夹角θ1设计为大于或等于第一夹角α1的一半与10°之差，且小于或等于第一夹角α1的一半与10°之和，既兼顾了自然对流的性能，又不影响风机20开启时的主动吸风效果。
进一步地，如图5所示，形成第二换热区124的第一换热段120的上边缘，与空调室内机1的风机20之间的间距s1，大于或等于壳体10在第二方向上的高度H的0.22倍，且小于或等于壳体10高度H的0.64倍。
在该实施例中，形成第二换热区124的第一换热段120靠近风机20设置，因此形成第二换热区124的第一换热段120与风机20的距离影响风机20的 主动吸风能力，具体地，形成第二换热区124的第一换热段120的上边缘与风机20距离越远，当第二入风口16未关闭时，会导致风机20抽吸到的未经换热的室内回风越多，影响空调室内机1的制冷效果，形成第二换热区124的第一换热段120的上边缘与风机20距离越近，则使得形成第二换热区124的第一换热段120的长度越小，进而会影响自然进风时的换热效果。因此，按照上述设置既兼顾了自然对流的性能，又不影响风机20开启时的主动吸风效果。
进一步地，第一换热段120包括多个翅片1200和多个换热管1202，多个换热管1202呈单排设置，多个翅片1200套设于换热管1202上。
在该实施例中，第一换热段120包括多个翅片1200和多个换热管1202，其中，任一第一换热段120的多个换热管1202呈单排设置(如图2中虚线a、b、c、d所示方向排列成一排)，这样，有利于降低空调器在自然对流状态下的风阻，同时也利于提升换热效率。
进一步地，相邻的两个翅片1200之间沿第三方向的间距与单个翅片1200的宽度之比大于或等于0.1，且小于或等于0.45。
在该实施例中，通过设置第一换热段120的翅片1200间距与翅片1200宽度的比值，有利于增大经换热器12换热前后的温度差，可以有效提升自然对流效果，提升空调室内机1的性能。
实施例八：
如图1和图10所示，根据本申请的一个实施例，包括上述任一实施例限定的特征，以及进一步地：壳体10包括：进风罩体105、底板106和端板107，第一入风口14和第二入风口16设于进风罩体105上；进风罩体105设置于底板106上，第一出风口18设于底板106上；端板107与底板106相连接，位于壳体10内，端板107上设有安装孔108，换热管1202的端部安装在安装孔108内。
在该实施例中，壳体10由罩体、底板106和端板107构成，罩体罩设于换热器12和风机20，第一入风口14和第二入风口16设于进风罩体105上，第一出风口18和第二出风口24形成在底板106上，换热管1202的端部通过端板107安装在底板106上，提高了换热器12的稳定性。
具体地，端板107上设有第一安装孔108和第二安装孔108，其中，相邻两组第一换热段120的两组换热管1202的端部分别安装在第一安装孔108和第二安装孔108内。
需要说明的是，第一安装孔108包括多个第一孔，第二安装孔108包括多个第二孔。
进一步地，如图1和图5所示，空调室内机1还包括：多个接水槽，设于壳体10内，任一第一换热段120的底部均设有接水槽。
在该实施例中，空调室内机1还包括多个接水槽34，将多个接水槽34分别设置在多个第一换热段120的底部，既保证了气流的流通效果，又能够收集冷凝水，避免冷凝水直接滴落。
进一步地，沿第二方向，向垂直于第二方向的平面内投影；在得到的投影面内，第一换热段120上的翅片1200靠近对应的接水槽34的一端的投影，位于对应的接水槽34的投影区域内。
在该实施例中，翅片1200靠近壳体10底壁的一端，沿翅片1200的宽度方向，其投影位于对应的接水槽34内，也即，沿第一方向，接水槽34的宽度能够覆盖翅片1200端部的片宽在第二方向上的投影，从而使得接水槽34能够完全接住翅片1200上流下的冷凝水，避免冷凝水由翅片1200直接滴落在壳体10底壁或者直接滴落在空调室内机1外部。
进一步地，沿第二方向，接水槽34的底壁设置设有排水孔。
在该实施例中，沿第二方向，接水槽34的底壁设有排水孔，从而可通过排水孔将冷凝水排出至壳体10外部。
进一步地，沿第三方向，接水槽34的底壁向接水槽34的中部倾斜。
在该实施例中，沿第三方向，接水槽34的底壁向接水槽34的中部倾斜设置，也即接水槽34由两端至中部向壳体10底壁倾斜，使得在第三方向上，接水槽34包括由一端向中部倾斜的第一底壁，和由另一端向接水槽34的中部倾斜的第二底壁，从而便于冷凝水顺利排出。
进一步地，接水槽34的第一底壁与第三方向的夹角大于或等于3°，第二底壁与第三方向的夹角大于或等于3°。
实施例九：
根据本申请的第二方面，还提出了一种空调器，包括：如上述任一实施例提出的空调室内机1。
本申请第二方面提供的空调器，因包括上述任一实施例提出的空调室内机1，因此具有空调室内机1的全部有益效果。
进一步地，空调器还包括控制***，控制***能够获取空调器的工作模式指令，并根据工作模式指令控制空调室内机1进行自然对流换热，或风机20主动换热，或者自然对流换热和风机20主动换热同时进行，以满足用户的不同需求，并最大程度地提高用户的舒适度。
具体地，本申请提供的空调室内机1可以应用于家用空调、中央空调多联机、商用风幕机、商用空调室内末端等多个产品。
实施例十：
根据本申请的一个具体实施例，提供了一种空调室内机1，包括至少两种工作模式，其中，包括自然风模式，可适用于睡眠模式制冷等；和主动强风模式，可适用于快速制冷或快速制热。
具体地，如图3所示，在自然风模式下，气流流向如图3中虚线箭头所示，风机20关闭，室内回风由第一入风口14和第二入风口16进入壳体10，与换热器12进行热交换，降温后的冷空气由于密度增大，在重力的作用下从第一出风口18流出至室内，而室内的热空气又会以回风的形式在进入壳体10，完成空气的循环。此时，第二出风口24在一定程度上充当进风口，少量的室内回风会通过第二出风口24经由镂空支架26在经过靠近风机20的第一换热段120被降温。
具体地，在主动强风模式下制冷或制热，通过风门22关闭第二入风口16，气流流向如图7中虚线箭头所示，在风机20的抽吸下，气流分两路由对应第一换热区122的第一入风口14、第一出风口18被吸入风机20内，其中，一路气流由靠近风机20进口202的第一入风口14经第一换热段120换热后流入风机20，一路气流由第一出风口18经第一换热段120降温后流入风机20，风机20竖直向下出风，形成一定的负压区域，在负压的驱动下，促使风机20另一侧的回风也通过类似上述的两个风口的进风方式被卷吸进入风道，也即，对一部分气流由远离风机20的第一入风口14经第 一换热段120换热后进入风机20、一部分气流由第一出风口18经第一换热段120换热后进入风机20，最终，风机20抽吸换热后的气流通过第二出风口24流出。
实施例十一：
根据本申请的一个具体实施例，提供了一种空调室内机1，包括自然对流和主动强风换热同时进行的模式，在该模式开启时，如图1至图11所示，风机20开启，在风机20的抽吸下，一路气流由靠近风机20进口202的第一入风口14经第一换热段120换热后流入风机20，一路气流由第一出风口18经第一换热段120降温后流入风机20，风机20竖直向下出风，形成主动出风，且形成一定的负压区域，在负压的驱动下，促使风机20另一侧的回风加快流动，也即，一路气流由远离风机20进口202的第一入风口14进入壳体10，与第一换热段120换热后由第一入风口14流出，形成自然对流换热，在该实施例中，由于风机20开启，一方面实现了主动送风，加大了制冷量，另一方面，由于风机20开启后形成负压，因此促进了风机20另一侧的气流的流动速度，加大了空调室内机1的空气量，进而增加了自然对流的制冷量。
