传统风管式空调室内机可以通过增设旋转风道组件，使其具有两种出风模式，一种是下风口102进风，侧风口101出风；另一种是侧风口101进风，下风口102出风。其中，壳体1包括固定壳部和可动壳部，可动壳部可向着远离固定壳部的方向移动，且移动行程允许旋转风道组件能够在壳体1内自由转动。旋转风道组件包括离心风轮组件。现有风管式空调室内机虽然能够实现风口切换出风，但是整个空调室内机的占用空间大，无法满足矮小楼层房屋内狭小天花板的空间要求。若将其安装在小尺寸的空调室内机上，为了保证机组送风性能，需要将蜗壳3尽量做大，但由于蜗壳3轮廓为非圆心结构，导致蜗壳3旋转时底部出现干涉，进而导致空调室内机卡顿甚至故障。
本公开实施例提供的空调室内机包括壳体1、风轮组件、蜗壳组件和调节机构。壳体1内固定有连接板13，所述连接板13上设置有调节机构；风轮组件包括转轴5和风轮6，所述转轴5固定穿设风轮6，转轴5可转动的设置在所述壳体1内，所述转轴5转动可带动所述风轮6绕第一旋转中心旋转；蜗壳组件包括密封隔板2和蜗壳3，所述密封隔板2固定设置有蜗壳3，所述密封隔板2与所述连接板13转动连接且能够沿第一方向移动，所述密封隔板2转动可带动所述蜗壳3绕第二旋转中心旋转；密封隔板2转动过程中，调节机构能够驱动密封隔板2相对连接板13在第一方向上产生位移，以调节第二旋转中心相对第一旋转中心的间距，其中，所述第一方向为背离所述蜗壳与所述壳体的干涉方向。
具体的，转轴5带动风轮6绕第一旋转中心旋转，第一旋转中心为转轴5轴心所在轴线，第一旋转中心位置固定。空调室内机在待机状态下，第二旋转中心与第一旋转中心重合，即风轮6的旋转中心点就是蜗壳3的旋转中心点。空调室内机需要进行不同出风模式的切换。在切换过程中，第二旋转中心位置是不断变化的，从而适应小尺寸空调室内机的需求。可以理解的，蜗壳3顶部位置随着旋转的开始，外轮廓逐渐减小，顶部空间越来越大，因此采用变旋转中心方案，蜗壳3边旋转边上移，从而能够充分利用机组内部空间，保证风机尺寸及机组送风性能。可以理解的，空调室内机也可以先上移再旋转。当需要设置蜗壳3边旋转边上移的方案，可以采用可调间距的齿轮系的调节机构；当需要设置蜗壳3先上移后旋转的方案，可以采用齿轮组和推杆的配合实现，在此对调节机构不做具体限定，只要能够调节第一旋转中心和第二旋转中心间的间距即可。
可选地，壳体1的侧板和底板上分别开设有相垂直的侧风口101和下风口102，密封隔板2转动，可使空调室内机在第一出风模式和第二出风模式间切换，第一出风模式下， 风由侧风口101进风，下风口102出风；第二出风模式下，风由下风口102进风，侧风口101出风；其中，第一出风模式或第二出风模式下，第二旋转中心与第一旋转中心重合，蜗壳3位于与风轮6同心位置；第一出风模式切换和第二出风模式切换过程中，调节机构调节第二旋转中心相对第一旋转中心的间距，使蜗壳3偏离风轮6轮心位置。
具体的，当空调室内机运行制热工况时，为第一出风模式，风由侧风口101进风，下风口102出风。空调室内机的出风方向为向下出风，由于热空气较轻，容易漂浮在房间顶部，通过下出风的方式，能够将热风送到人体区域，提升用户所在区域的舒适度。当空调室内机运行制冷工况时，为第二出风模式，风由下风口102进风，侧风口101出风。通过侧出风的方式，能够将冷风从上往下降落，使制冷送风更均匀。当空调室内机出风时，蜗壳3处于静止状态，此时，调节机构不发挥作用，第二旋转中心重合于第一旋转中心。当空调室内机进行风向切换过程中，蜗壳3进行旋转，以使蜗壳出风口朝向空调室内机的侧风口101或者下风口102，在蜗壳3旋转过程中，调节机构不断调节蜗壳3底部距离空调室内机壳体1内壁间的空间间距，防止类似蜗牛壳结构的蜗壳3旋转过程中与内体内壁发生干涉，进而导致空调室内机卡顿设置停机故障的问题。在蜗壳3旋转过程中，第一旋转中心位置固定，第二旋转中心与第一旋转中心间的间距，先逐渐增大后逐渐缩小。这样，无需为蜗壳3旋转提供额外的避让空间，并且能够保证空调室内机的送风性能以及运行稳定性。
可选地，第一方向是指垂直于壳体1的底板的方向；或者垂直于壳体1的侧板的方向。第一风向可具体根据空调室内机的安装位置进行选择。可以理解的，当空调室内机作为风管机安装于天花板上时，由于天花板空间有限，因此对风管机的厚度要求较高。对于较薄的风管机而言，蜗壳3底部与空调室内机的底板内壁易产生干涉的问题，因此，风管机的第一方向为垂直于壳体3的底板方向。
可选地，空调室内机还包括动力组件。动力组件包括第一驱动装置41、主动齿轮42和从动齿轮43。第一驱动装置41固定在连接板13上，第一驱动装置41包括驱动输出端；主动齿轮42设置于驱动输出端上；从动齿轮43与主动齿轮42相啮合，从动齿轮43穿设连接板13与密封隔板2固定连接；其中，第一驱动装置41驱动主动齿轮42转动，进而带动从动齿轮43转动，以使从动齿轮43带动密封隔板2相对连接板13转动。具体的，空调室内机壳体1内的两侧壁均固定有连接板13，密封隔板2可转动的设置在两个连接板13之间。从动齿轮43和密封隔板2位于其中一个连接板13的两侧，从动齿轮43和密封隔板2固定连接。通过第一驱动装置41驱动主动齿轮42转动，进而能够带动从动齿轮43旋转，以使密封隔板2相对连接板13转动。
可选地，从动齿轮43包括齿轮本体、轮齿和连接柱。轮齿位于齿轮本体的头部，轮齿与主动齿轮42相啮合，轮齿包括第一弧形齿段和第二弧形齿段，第二弧形齿段位于两个第一弧形齿段之间，第二弧形齿段的齿顶圆直径大于第一弧形齿段的齿顶圆直径；连接柱与密封隔板2固定连接；第一弧形齿段的齿顶圆圆心和第二弧形齿段的齿顶圆圆心重合，二者的齿顶圆圆心均位于连接柱上，其中，从动齿轮43具有调节机构的功能，在转动过程中可以调节第二旋转中心相对所述第一旋转中心的间距。齿轮本体为扇形，其扇形角θ的范围为：75°≤θ≤85°。
具体的，从动齿轮43包括齿轮本体、轮齿、凸轮和连接柱。齿轮本体为扇形，轮齿位于齿轮本体的头部，轮齿与主动齿轮42相啮合；凸轮位于齿轮本体的尾部；连接柱与密封隔板2固定连接；其中，连接柱为轮齿的分度圆圆心。轮齿的两端分别为第一端部和第二端部，主动齿轮42啮合于所述第一端部，空调室内机运行第一出风模式；主动齿轮42啮合于第二端部，空调室内机运行第二出风模式。相比于传统可换向送风的空调室内机，本申请无需额外设置元件，如微控开关，便可以进行不同出风模式的切换，节省了元件的成本和空调室内机的内部空间。凸轮的设置能够使连接板13获得更大的空间，以便安装或避让其他元件。连接柱设置在轮齿的分度圆圆心上，能够使密封隔板2和蜗壳3绕着圆心所在直线进行轴向旋转。
在第一出风模式和第二出风模式切换过程中，主动齿轮42带动从动齿轮43转动。其中，靠近第一端部的第一弧形齿段为第一齿段，靠近第二端部的第一弧形齿段为第三齿段。主动齿轮42转动过程中，依次啮合于第一齿段、第二弧形齿段和第三齿段；或者，依次啮合于第三齿段、第二弧形齿段和第一齿段。第二弧形齿段的齿顶圆半径大于第一弧形齿段的齿顶圆半径。这样，在蜗壳3旋转过程中，蜗壳3的旋转中心先沿着第一方向上移，后逐渐回到原位，从而能够规避蜗壳3旋转过程中，蜗壳底部与空调室内机的底板内壁发生干涉的问题。
现有空调室内机在模式切换时，风轮组件需要相对壳体1转动80°-100°或170°-190°的转动范围，使可换向送风的空调室内机占用空间大。本申请中设置的齿轮本体的扇形角θ的范围为：75°≤θ≤85°，仅需旋转75°-85°的范围便能够实现在垂直设置的侧风口101和下风口102间旋转切换出风。
空调室内机处于第一出风模式，蜗壳出风口所在平面与第一底板的夹角范围在5°到10°之间，风由侧风口101进风，下风口102出风；空调室内机处于第二出风模式，蜗壳出风口所在平面与第一底板的夹角范围在80°到85°之间，风由下风口102进风，侧风口101出风。因此本申请的蜗壳3仅需要进行小角度转动，便能够在两个垂直风口间切换出 风，且无需预留蜗壳3旋转的避让空间，使空调室内机在整机厚度200mm空间内进行风口切换出风。本申请的空调室内机的空间占有率小，进一步解决了因天花板空间过小而无法安装换向出风的空调室内机的问题。优选地，齿轮本体的扇形角θ为79°，从而能够在整机厚度200mm空间内，使风管式空调室内机具有更好的出风性能。
可选地，空调室内机还包括轴承9，轴承9可移动地设置于连接板13上，轴承9包括轴承内圈和轴承外圈，轴承内圈固定套设在连接柱上，轴承外圈与缓冲本体固定连接，从动齿轮43转动可带动轴承9在第一方向上转动。这样，既能够避免密封隔板2相对连接板13转动时产生摩擦，避免元件不必要的损伤；又能避免蜗壳3旋转过程中，缓冲件在蜗壳3旋转方向上产生形变的问题。
可选地，调节机构还包括缓冲机构14。缓冲机构14包括缓冲本体141和位于缓冲本体上的弹性件142，缓冲本体141与主动齿轮42位于从动齿轮43的两侧；弹性件142位于缓冲本体141上，弹性件142用于在密封隔板2位移过程中提供阻尼位移的阻尼力，以限定主动齿轮42与从动齿轮43啮合；其中，主动齿轮42在弹性件142的弹性方向的延长线上。这样，能够避免从动齿轮43偏离主动齿轮42的问题，使二者始终处于啮合传动的关系中。弹性件142的弹性方向为从动齿轮43轮心和主动齿轮42轮心所在延长线上，这样，能够使弹性件142更稳定地调节间距。
可选地，缓冲本体包括弧形条框和凸柱。弧形条框包括同心设置的内弧面和外弧面，内弧面固定贴合在轴承外圈上；凸柱固定在外弧面上；其中，缓冲件包括弹簧，弹簧的一端套设在凸柱上。弧形条框套设在扇形齿轮的连接柱外侧轴承9上，且位于远离主动齿轮42的一侧。凸柱的数量为多个，多个凸柱上套设有弹簧，弹簧自然状态下的长度要远大于凸柱长度。弹簧的一端在凸柱上，并压在外弧面上，弹簧的另一端抵接在连接板13开设的限位孔21内，从而调节密封隔板2在竖直方向上的位移，进而调节蜗壳3的旋转中心位置，避免蜗壳3旋转过程中出现运行干涉的问题，提高空调室内机的运行稳定性和出风性能。
可选地，连接板13开设有限位孔21，连接柱穿设限位孔21，齿轮本体和密封隔板2位于连接板13的两侧；其中，弹簧的另一端抵接在限位孔21内侧壁上，限位孔21用于为连接柱提供运行轨道，以使扇形齿轮旋转过程中带动蜗壳3偏离风轮6的轮心，并能够在弹簧的弹性力作用下使蜗壳3回到与风轮6同心位置上。这样，空调室内机在出风时，第二旋转中心和第一旋转中心重合，使蜗壳3和风轮6的旋转轴5线重合，提高空调室内机的送风稳定性。在切换过程中，又能使蜗壳3边旋转边上移，节省空间，且能够避免蜗壳3底部与壳体1内壁发生干涉的问题。
可选地，蜗壳3旋转时的最大偏心量为第二弧形齿段的齿顶圆与第一弧形齿段的齿顶圆的径向间距；其中，限位孔21在第一方向上的长度大于或等于蜗壳3旋转时的最大偏心量，以为轴承的移动提供避让空间。
可选地，空调室内机的部分部件间存在如下尺寸关系：h＝k*D，k∈[2.5％,5.5％]；h为蜗壳3旋转时的最大偏心量，D为风轮6的直径。其中，蜗壳3旋转时的最大偏心量的定义公式为：h＝sd1-sd0，第一弧形齿段的齿顶圆的半径为sd0，第二弧形齿段的齿顶圆的半径的半径为sd1。这样，既能保证主动齿轮42与从动齿轮43处于啮合传动状态，并且能够根据风轮6和轮齿的尺寸，更好的调控蜗壳3旋转时的最大偏心量，合理利用空调室内机的内部空间。
可选地，限位孔21位于连接板板面上且垂直弹簧弹性方向上的孔内间距大于或等于轴承9外圈的外直径；或者，限位孔21位于连接板板面上且垂直弹簧弹性方向上的孔内间距大于或等于弧形条框的两端端部间的间距。这样，能够使第二旋转中心仅在竖直方向上相对第一旋转中心进行偏移，提高了空调室内机的稳定性。
可选地，轮齿的齿面包括齿顶和齿根，扇形齿轮旋转以使轮齿从齿根到齿顶之间逐渐过渡，以使与主动齿轮相啮合的扇形齿轮能够从第一弧形齿段到第二弧形齿段平稳过渡，或者从第二弧形齿段到第一弧形齿段平稳过渡。通过弹簧与轮齿的配合，使得旋转时出现偏心，在弹簧的弹力下使得蜗壳3回到初始位置。
可选地，密封隔板2设置有多个避让缺口22，多个蜗壳3的出风口一一卡接在多个避让缺口22上。密封隔板2包括第一隔板和第二隔板。第一隔板开设有避让缺口22，蜗壳出风口固定在避让缺口22上；第二隔板与第一隔板垂直固定连接；其中，第二隔板数量为两个，分别位于蜗壳3进风口的两侧，第一隔板位于两个第二隔板之间。这样，能够使第一隔板与第二隔板间连接更可靠，定位更准确。密封隔板2不仅对多个蜗壳3起到了一定承载和支撑作用，防止壳体1变形。而且能够带动蜗壳3转动，使空调室内机无需额外的风道切换元件便能实现风口的切换出风。
可选地，离心风机的数量为多个，转轴5固定穿设多个离心风机的风轮6，转轴5轴向转动可带动多个风轮6旋转。转轴5与密封隔板2互相独立，从而使蜗壳3和风轮6能够独立工作，以实现多种出风模式。其中，离心风机的数量在此不做具体限定，其个数可根据实际使用情况设置任意数量。
可选地，蜗壳3包括上蜗壳部和下蜗壳部，上蜗壳部包括蜗壳出风口和上壳面，上蜗壳部一体成型。多个上蜗壳部固定卡接在密封隔板2的多个避让缺口22上，下蜗壳部与上蜗壳部一一对应连接。下蜗壳部和上蜗壳部可采用卡扣的形式相连接，也可采用其他可 拆卸的连接形式，在此不做限定。为了加强上蜗壳部的强度，可增设L形固定板，L形固定板的两侧边分别固定在上蜗壳部的出风口位置和密封隔板2上。
可选地，空调室内机还包括挡板7和第二驱动装置8。挡板7包括枢转轴71，挡板7通过枢转轴71与密封隔板2枢转连接；第二驱动装置8固定在密封隔板2上，第二驱动装置8用于驱动枢转轴71轴向旋转以带动挡板7转动，挡板7用于隔离蜗壳3的进风气流和出风气流。具体的，密封隔板2将蜗壳出风口和蜗壳3两侧进风口隔离开，密封隔板2下部可通过枢转轴71与挡板7枢转连接。密封隔板2可带动蜗壳3旋转，以使蜗壳出风口的出风方向由下风口102切换到侧风口101，之后通过调节挡板7转动的角度，使风道形成完整的风道曲线，进而使进风风道和出风风道分隔开，避免了进风风道和出风风道因存有空隙进而相互干扰造成湍流和紊流的问题，有利于降低空调室内机内的噪音，提升空调室内机的送风性能。
可选地，挡板7为弧形板，挡板7的弧形角度风道的弧度相契合。可转动挡板7能够使空调室内机在第一出风模式和第二出风模式下，均能够形成完整的风道曲线，不仅避免了蜗壳3进风气流和出风气流相互影响，而且优化了送风风道，提升了送风性能。
可选地，连接板13设置有避让导轨131，避让导轨131为弧形槽，密封隔板2带动第二驱动装置8转动，避让导轨131为第二驱动装置8的转动提供轨道。同时，避让导轨131能够在第一出风模式和第二出风模式切换中，起到对第二驱动装置8的限位作用。避让导轨131的弧形角的范围为75°-85°。通过弧形缺槽的设置，能够使空调室内机整机厚度200mm空间内，获得更大的风道空间。
可选地，空调室内机还包括控制单元，被配置为由第二出风模式切换为第一出风模式过程中，先控制挡板7相对密封隔板2转动第一预设角度后，控制密封隔板2带动挡板7整体旋转第二预设角度，再控制挡板7相对密封隔板2转动第三预设角度；由第一出风模式切换为第二出风模式过程中，先控制挡板7相对密封隔板2转动第三预设角度后，控制密封隔板2带动挡板7整体旋转第二预设角度，再控制挡板7相对密封隔板2转动第一预设角度；其中，密封隔板2带动挡板7转动过程中，第二旋转中心先逐渐偏离第一旋转中心，后逐渐调整回到第一旋转中心所在位置。这样，既能避免出现气流紊流的问题，同时能够在整机厚度200mm内，使蜗壳3高度能够设定在180mm到190mm的范围内不会产生干涉问题，提高了空调室内机的出风性能。其中，第一旋转角度范围为55°-65°，第二旋转角度范围为75°-85°，第三旋转角度范围为5°-15°。
可选地，空调室内机还包括换热器和接水盘。换热器倾斜设置在换热腔内；接水盘固定在第一底板上，接水盘位于换热器下方；其中，空调室内机由侧风口101出风时，挡板 7与接水盘的外表面无缝贴合。
具体的，换热器包括基板和多个翅片。多个翅片垂直于侧风口101。在第一出风模式下，蜗壳3由下风口102斜向下出风；在第二出风模式下，由于蜗壳3旋转角度为锐角，进而导致蜗壳出风口处的出风方向为侧向下出风，易使冷风直吹用户，体验感较差。通过将换热器的多个翅片倾斜设置在换热器的基板表面，使多个翅片与第一侧板相垂直，能够使冷风在侧风口101处水平出风，增大了侧风口101处的气流到人体的距离，避免风管式空调室内机出风直接对着使用人员的身体。
当风管式空调室内机运行制热工况时，出风方向为向下出风，由于热空气较轻，容易漂浮在房间顶部，通过下出风的出风方式，能够将热风送到人体区域，使用户所在区域空间的舒适性更好。当风管式空调室内机运行制冷工况时，出风方向为侧向出风，制冷时冷空气从上往下降落，制冷送风更加均匀。在第一出风模式下，挡板7通过转动可抵接在接水盘的外沿，从而使蜗壳3出风气流和进风气流完全分隔开。这样，避免出现空气紊流的问题，提升了空调室内机的送风性能。
可选地，空调室内机还包括密封衬垫，固定在密封隔板2上，密封隔板2可带动密封衬垫转动；其中，壳体1还包括第二底板，第二底板平行于第一底板，空调室内机由侧风口101出风时，密封衬垫贴合第二底板。在第一出风模式下，蜗壳3的上壳面与第一底板存在偏移角度，所以密封隔板2与第一底板间具有空隙。通过增设密封衬垫填补空隙，从而更好地隔离蜗壳3的进风气流和出风气流。
可选地，空调室内机还包括密封衬垫和顶板。顶板平行于底板，密封衬垫固定在第二底板上。空调室内机由侧风口101出风时，密封隔板2抵接在密封衬垫上，从而封堵密封隔板2与顶板间的空隙，避免出现进风气流和出风气流发生紊流的问题，提升送风性能。
可选地，空调室内机还包括固定座10和第三驱动装置12。固定座10固定在壳体1上，转轴5穿设固定座10；第三驱动装置12用于驱动转轴5轴向旋转，从而使风轮6旋转出风。
可选地，空调室内机还包括固定架11和滚动轴承9。固定架11固定在壳体1上；滚动轴承9的外圈与固定架11固定连接，内圈与转轴5固定连接。固定架11固定在空调室内机的壳体1上，固定架11嵌设有滚动轴承9，滚动轴承9外圈与固定架11固定连接，轴承9内圈与转轴5固定连接，以使转轴5转动连接到壳体1上。固定架11和固定座10共同承担转轴5的载荷，从而使转轴5更加稳定的运行。
