参照图1所示，本公开一种实施例的整体式空调，为双风管结构的整体式空调，包括进排风组件10和室外换热组件20。具体的，进排风组件10与室外换热组件20连接，室 外换热组件20包括室外换热器21和排风蜗壳22，进排风组件10的其中一个风管引导室外的空气从整体式空调的进风口30进入，空气通过室外换热器21进行换热后，由排风蜗壳22将换热后的空气通过进排风组件10的另一风管排出至室外，从而实现整体式空调的换热过程。
参照图2和图3所示，本公开一种实施例的进排风组件10，包括第一风管100和第二风管200，第一风管100内限定出第一风道110，第一风道110与排风蜗壳22的出风口连通，使得第一风道110的密封性好，保证了从排风蜗壳22排出的风可以全部通过第一风道110排到室外；第二风管200套设于第一风管100外，第二风管200的内壁与第一风管100的外壁之间限定出第二风道210，第二风道210与整体式空调的进风口30连通，使得第二风道210的密封性好，从而将第二风道210和第一风道110相互隔离，即进风和排风相互隔离，避免了第二风道210和第一风道110之间发生热交换，从而影响整体式空调的换热效率，而且安装结构更加简单，装配更加方便。
可以理解的是，作为另一种实施方式，第一风道110可与整体式空调的进风口30连通，而第二风道210与排风蜗壳22连通，可参考图2所示结构将第二风管210与整体式空调的进风口30的连接方式，与第一风管110与排风蜗壳22的连接方式进行互换设计即可实现进排风组件10的连接，该连接方式也可以实现进风和排风的相互隔离，避免了进风和排风之间发生热交换。
本公开实施例的进排风组件10通过设置第一风管100和套设于第一风管100外的第二风管200形成双风管结构，相对于由两个分体式独立风管组成的双风管结构，结构更为简单美观，便于用户对双风管结构进行安装和调节，提升了用户体验；而且采用双风管结构的整体式空调能实现全屋制冷或制热，提高整体式空调的换热效率。
参照图2所示，本公开一种实施例的进排风组件10，还包括密封板300和固定环400，密封板300开设有第一通孔310，第一通孔310与第二风管200相连，第一通孔310用于使室外环境的空气进入第二风道210内；固定环400设于第一通孔310内，固定环400内限定出第二通孔410，第二通孔410与第一风管100相连，第二通孔410用于使第一风道110内的空气向室外环境排出。需要说明的是，密封板300与固定环400相连形成固定结构，该固定结构可通过固定件将密封板300和固定环400连接，或将密封板300和固定环400进行一体成型连接，在此不再具体限定。密封板300和固定环400可以将第二风管200和第一风管100进行定位，避免了第二风管200和第一风管100相互错位从而造成挡风，提高了连接的可靠性，使用户操作密封板300的过程中，可同时将第二风管200和第一风管100进行同步拉伸安装或收缩折叠，可便于用户对进排风组件10进行整体的拉伸和收缩，提高了进排风组件10安装、调节和拆卸的效率，进一步提升了进排风组件10的易用 度，提高了用户体验。进一步说明的是，密封板300和固定环400可通过一体注塑成型，其加工更加方便，结构更加稳定。
参照图4和图5所示，第一风管100的长度可调，举例来说，第一风管100可以为伸缩软管或硬质套管等结构，在此不再具体限定。第一风管100可相对于固定环400的轴向向外拉伸，即第一风管100可以朝向室外移动从而伸出一定的距离，例如伸出200mm至300mm的长度，从而使第一风管100朝向室外的一端端部和第二风管200朝向室外的一端端部相错开一定的距离，从而使进排风组件10的进风端和出风端隔开。可以理解的是，当第一风管100用于排风，而第二风管200用于进风时，可避免第一风管100排出的经过换热后的空气又被第二风管200吸入至室外换热组件20，从而形成串风现象，导致整体式空调能力能效的下降。进一步来说，如果整体式空调处于制冷模式，第一风管100向室外排出热风，通过设计第一风管100向室外移动延伸的结构，可避免热风直接被第二风管200吸回到室外换热器21中，从而提高了整体式空调的换热效率。
参照图5和图6所示，固定环400的内壁为光滑表面，使得用户在对位于固定环400朝向室外一端的第一风管100进行拉伸或收缩调节时更加顺畅，而且减少了对第一风管100外壁的磨损，提高了第一风管100的耐用性。
参照图4和图6所示，固定环400的内壁沿周向间隔设有若干个第一卡扣420，第一风管100的上端设有与第一卡扣420相配合的第一接头120，第一接头120的外壁与若干个第一卡扣420卡接以固定第一风管100，该结构可以限制第一风管100相对于固定环400朝向下滑动，避免固定环400与第一风管100脱离，而且可方便地使第一风管100沿远离第一卡扣420的方向移动，即向室外延伸。可以理解的是，采用卡接的方式，其安装和拆卸方便、连接结构稳定。第一卡扣420的数量可设置为1个、2个、3个或多个，当第一卡扣420设置为多个时，多个第一卡扣420可均布设置于固定环400的内壁上，而且实际生产中可根据整体式空调采用的不同尺寸的第一风管100对第一卡扣420的数量进行设计。
参照图7所示，密封板300在朝向第二风管200的一端凸出设有定位环320，定位环320与密封板300之间形成定位台阶321，第二风管200与定位台阶321相连，限制了第二风管200相对于密封板300朝向上滑动，避免了第二风管200向室外脱出；而且使第二风管200与密封板300之间的连接更加可靠，不容易发生松脱。
参照图3和图7所示，定位环320沿周向间隔设有若干个第二卡扣322，第二风管200的上端设有与第二卡扣322相配合的第二接头220，第二接头220与若干个第二卡扣322卡接以固定第二风管200，限制了第二风管200相对于密封板300朝向下滑动，避免了第二风管200与密封板300相互脱开，且结合定位台阶321的结构，可以使第二风管200完全卡接固定于密封板300上。可以理解的是，采用卡接的方式，其安装和拆卸方便、连接 结构稳定。第二卡扣322的数量可设置为1个、2个、3个或多个，当第二卡扣322设置为多个时，多个第二卡扣322可均布设置于定位环320上，而且实际生产中可根据整体式空调采用的不同尺寸的第二风管200对第二卡扣322的数量进行设计。
在本公开其中一些实施例中，参照图2所示，固定环400与密封板300之间设有连接筋500，使密封板300和固定环400构造成一个整体，从而使用户操作密封板300的过程中，可同时将第二风管200和第一风管100进行同步拉伸安装或收缩折叠，可便于用户对进排风组件10进行整体的拉伸和收缩，提高了进排风组件10安装、调节和拆卸的效率，进一步提升了进排风组件10的易用度，提高了用户体验。
在本公开其中一些实施例中，进一步的，参照图6所示，连接筋500设有多个且多个连接筋500沿固定环400的周向间隔布置，提高了固定环400和密封板300连接的稳定性，提高了密封板300的结构强度，进而延长了进排风组件10的使用寿命。
在本公开其中一些实施例中，参照图7和图9所示，第一通孔310的轴心和第二通孔410的轴心不重合，即第二风管200和第一风管100偏心设置，可以将第二风道210和第一风道110沿垂直方向分开，使得室外的空气进出第二风管200时更加顺畅，减少第一风管100对第二风道210进出风造成的阻力，从而提高整体式空调的能效。
在本公开其中一些实施例中，参照图6和图7所示，密封板300、固定环400和连接筋500通过一体注塑成型，其加工更加方便，结构更加稳定。
参照图8和图9所示，本公开一种实施例的整体式空调，包括以上实施例的进排风组件10。本实施例的整体式空调通过进排风组件10设置密封板300和固定环400连接固定的结构，密封板300开设有第一通孔310与第二风管200相连，固定环400设有第二通孔410与第一风管100相连，使得第二风管200套设于第一风管100外从而形成稳定的双风管结构，避免了第二风管200和第一风管100相互错位从而造成挡风，提高了连接的可靠性，并提高了整体式空调的能效；而且通过操作密封板300即可实现第二风管200和第一风管100的同步拉伸或收缩，便于用户对进排风组件10进行安装和调节，提高了用户体验。
参照图10所示，本公开另一种实施例的整体式空调，通过进排风组件10设置密封板300和固定环400连接固定的结构，使得第二风管200套设于第一风管100外从而形成稳定的双风管结构，第一风管100可相对于固定环400的轴向朝向室外伸出一定的距离，从而使第一风管100朝向室外的一端端部和第二风管200朝向室外的一端端部相错开一定的距离，避免第一风管100和第二风管200在室外一端形成串风现象，进一步提高了整体式空调的能力能效。
上面结合附图对本公开实施例作了详细说明，但是本公开不限于上述实施例，在所述 技术领域普通技术人员所具备的知识范围内，还可以在不脱离本公开宗旨的前提下作出各种变化。
