参照图1和图4所示，本公开一种实施例的移动空调，包括机壳100和出风壳体200，出风壳体200安装于机壳100内，出风壳体200具有进风孔210和出风孔220，进风孔210处安装有换热器300，出风壳体200在出风孔220处安装有送风机构400，参照图8所示，机壳100的后端设于背板110，背板110开设有第一进风口111，第一 进风口111与进风孔210相对设置并连通，第一进风口111与外界环境连通，第一进风口111为移动空调的主进风口，用于供外界环境的空气进入换热器300进行换热。当移动空调制冷运行时，出风壳体200内的风轮(图中未示出)转动，带动空气从第一进风口111进入机壳100内，并通过换热器300进行换热，换热后的空气在风轮的引导作用下从送风机构400吹出，对外界环境的温度进行调节。
参照图1和图2所示，本公开一种实施例的移动空调，机壳100设有后壳体140，后壳体140通过机壳100的后端相对于背板110凸出而形成，后壳体140与第一进风口111沿上下方向分隔布置。后壳体140开设有通风孔120，通风孔120可以设置为一个或多个长条状结构，长条状结构可以沿水平方向延伸设置，或沿垂直方向延伸设置，在此不再具体限定；另外通风孔120还可以设有多个且多个通风孔120通过组合构造成格栅结构，在此不再具体限定。参照图3和图4所示，机壳100内形成有与通风孔120连通的风道130，风道130的两端分别连接通风孔120和进风孔210，从而将通风孔120补充的风量引导至出风壳体200内，从而增强了换热器300的换热效率，提高了移动空调的换热效果，增大了送风机构400的出风量，使得用户体验感更加。而且，当移动空调靠墙安装时，因为第一进风口111被墙面或位于背板110后方的风管500进行阻挡，有效进风面积小，进风量少，此时通风孔120可以起到补充风量的作用，提升移动空调的能力和实际的制冷制热效果。
在本公开的一些实施例中，风道130通过机壳100的内部结构之间限定出，风道130的设置方式可以采用每个通风孔120均独立设置一个风道130，也可以采用多个通风孔120共用一个风道130。
参照图4和图5所示，在本公开的一些实施例中，移动空调还包括中隔板600，中隔板600位于机壳100内，中隔板600和机壳100之间形成用于容纳出风壳体200的腔体，出风壳体200安装于中隔板600上，中隔板600和后壳体140之间形成密封的腔体，腔体内限定出连通通风孔120和进风孔210的风道130，使得风道130的密封性较好，避免通风孔120的进风气流在机壳100内发生窜风，进而导致进风的风量损失。另外，通风孔120通过密封的风道130将补充进风气流汇入至出风壳体200内，从而提高移动空调的换热效率。
参照图4、图5和图6所示，在本公开的一些实施例中，移动空调还包括位于后壳体140内的导风器700，导风器700的两端分别连接中隔板600和风管500，使得移动空调与室外环境换热的进风道与风道130隔离且相互密封，避免两者之间发生窜风，从而影响送风机构400的送风效果。另外，参照图8和图9所示，导风器700的外壁呈流线型，导风器700、中隔板600和后壳体140之间形成风道130，因此风道130的阻力更小，进风更加顺畅，增强了换热器300的换热效率，提高了移动空调的换热效率，而且能有效降低进风噪音。
参照图1和图2所示，为了整体结构设计美观，风管500一般安装于后壳体140的上端且位于背板110的后端，因此会对背板110上的第一进风口111存在一定的阻挡，从而影响出风壳体200的进风。所以，通过将通风孔120设置为沿风管500的周边间隔设置，能在第一进风口111的附近位置进一步补充进风量，可以有效提高出风壳体200的进风量，从而提高了移动空调的换热效率；而且通风孔120的布局更加紧凑，使得移动空调的结构更加紧凑。另外，通风孔120可以设于后壳体140沿左右方向的壁面上，可以理解的是，通风孔120可以布置于后壳体140的左侧壁面、右侧壁面或左右侧壁面。通风孔120设置于侧壁上，可以减少风管500对通风孔120的影响，保证通风孔120的补充风量的效果。
参照图2所示，为了进一步增加进风效果，通风孔120可以设置有多个，多个通风孔120分布设于后壳体140的后壁面和上壁面或其他侧壁上，从而进一步提高了补充风量的效果，提升移动空调的换热效果。
参照图2所示，在本公开的一种实施例中，通风孔120的宽度方向的尺寸为d，d满足：d≥20mm。需要说明的是，通风孔120的宽度方向尺寸d指的是通风孔120的最小直径或较短的一边的长度，满足上述尺寸的情况下，通 风孔120的进风阻力小，进风更加顺畅，而且通风孔120可以方便用户对通风孔120内部的结构进行清洁。
参照图2所示，在本公开的另一种实施例中，通风孔120的宽度方向的尺寸d满足：0<d≤8mm。满足上述尺寸的情况下，通风孔120可以避免异物从通风孔120落入机壳100内，对移动空调的运行造成损伤，而且便于对后壳体140的侧壁进行清洁。
参照图7和图8所示，在本公开的一些实施例中，第一进风口111可拆卸连接有第一过滤组件150，第一过滤组件150通过卡扣151连接于背板110上，卡扣151可以设有多个，多个卡扣151沿第一过滤组件150的周向设置；为了方便第一过滤组件150从上往下插入安装，第一过滤组件150的下端一般不设置卡扣151。当然，第一过滤组件150也可以采用其他便于拆卸的方式安装于背板110上，例如螺栓等方式。需要说明的是，第一过滤组件150覆盖在第一进风口111，对第一进风口111进入的空气进行过滤，避免空气对换热器300造成污染，而且还能提升送风机构400吹出的空气的质量，提升了用户体验。
参照图4和图9所示，在本公开的一些实施例中，机壳100内还形成有位于风道130内的第二进风口160，第二进风口160形成于中隔板600和后壳体140之间，第二进风口160位于第一进风口111的下方。为了避免通风孔120的进风气流污染换热器300的表面，第二进风口160处还设有第二过滤组件170，第二过滤组件170对通风孔120的进风气流进行过滤，避免补充进风对换热器300造成污染，而且还能提升送风机构400吹出的空气的质量，提升了用户体验。
参照图5和图8所示，在本公开的一些实施例中，第二过滤组件170与第一过滤组件150固定连接，用户在拆出第一过滤组件150的同时可以一同拆出第二过滤组件170，第二过滤组件170可以和第一过滤组件150一样通过第一进风口111向上抽出，使得第二过滤组件170的拆装更加方便，便于用户清洗。可以理解的是，第二过滤组件170和第一过滤组件150可以构造为一体件，第二过滤组件150通过将第一过滤组件150向下延伸形成，同样可以便于用户同时拆出第一过滤组件150和第二过滤组件170。
具体的，参照图7所示，在本公开的一些实施例中，第一过滤组件150包括安装架152和过滤网(图中未示出)，安装架152上设置与机壳100可拆卸连接的结构，例如卡扣151等。安装架152上还形成有用于容置过滤网的凹槽(图中未示出)，过滤网可固定于凹槽内；当然，过滤网也可以通过粘接、螺接等方式固定于安装架152上，在此不再具体限定。需要说明的是，安装架152的表面设有格栅153，空气通过格栅153进入过滤网进行过滤，过滤后的空气再进入换热器300进行换热，能有效阻隔空气中的尘埃等微粒，避免换热器300表面积聚杂质，进而影响换热器300的换热效率。
参照图5和图6所示，在本公开的一些实施例中，中隔板600安装有定位架610，定位架610位于机壳100内，定位架610位于第二进风口160，用于对第二过滤组件170进行定位。而且，定位架610还具有导向部611，导向部611用于将风道130导向至第二进风口160，使得通过风道130的补充进风气流均通过第二过滤组件170进行过滤，保证了补充进风气流进入到换热器300时的洁净度。在本实施例的一些实施例中，定位架610设有与第二过滤组件170定位配合的定位槽612，第二过滤组件170安装于定位槽612内，其安装更加稳定，而且定位槽612具有一定的导向作用，便于第二过滤组件170滑动拆出，提升了用户体验。
参照图10、图13和图14所示，本公开一种实施例的移动空调，包括机壳100和出风壳体200，出风壳体200安装于机壳100内，出风壳体200具有进风孔210和出风孔220，进风孔210处安装有换热器300，出风壳体200在出风孔220处安装有送风机构400，出风壳体200内安装有风轮(图中未示出)，风轮带动室内环境的空气通过换热器300，换热器300对空气进行换热，实现对空气的制冷或加热，换热后的空气进入出风壳体200中，并通过送 风机构400吹出至室内环境中，实现对室内环境温度的调节。
参照图10和图12所示，机壳100包括上壳体110’，上壳体110’开设有第一进风口111，第一进风口111与外界环境连通，第一进风口111为移动空调的主进风口，第一进风口111与换热器300之间连通，并且形成有第一进风通道，作为出风壳体200的主要进风通道，用于供外界环境的空气进入换热器300进行换热。当移动空调制冷运行时，出风壳体200内的风轮转动，带动空气从第一进风口111进入机壳100内，并通过换热器300进行换热，换热后的空气在风轮的引导作用下从送风机构400吹出，对外界环境的温度进行调节。
参照图10、图11和图12所示，本公开一种实施例的移动空调，机壳100还包括下壳体120’，下壳体120’和上壳体110’可采用一体成型的方式制造，例如一体注塑成型。下壳体120’相对于上壳体110’向后凸出设置，下壳体120’的上部设有安装部122，安装部122用于固定风管500。由于本实施例的移动空调的风管500安装位置固定在第一进风口111的后方，因此风管500会对部分第一进风口111进行遮挡，从而影响移动空调的进风量。为了提升移动空调的进风量，下壳体120’开设有第二进风口121，可以理解的是，第二进风口121位于第一进风口111的下方且分隔布置。第二进风口121与外界环境连通，第二进风口121可以作为移动空调的辅助进风口，第二进风口121与换热器300之间连通，并且形成有第二进风通道，作为出风壳体200的补充进风通道，用于供外界环境的补充空气进入换热器300进行换热。第二进风口121与安装部122错开设置，使得安装部122与风管500连接形成的风道与第二进风通道之间相互隔绝，不会发生窜风，影响换热效率。
参照图13和图14所示，从第二进风口121补充的风量通过第二进风通道引导至出风壳体200内，从而增强了换热器300的换热效率，提高了移动空调的换热效果，增大了送风机构400的出风量，使得用户体验感更加。而且，当移动空调靠墙安装时，因为第一进风口111被墙面或风管500阻挡，有效进风面积小，进风量少，此时第二进风口121可以起到补充风量的作用，提升移动空调的能力和实际的换热效果。
可以理解的是，第二进风通道通过机壳100的内部结构之间限定出，第二进风通道的设置方式可以采用每个第二进风口121均独立设置一个第二进风通道，也可以采用多个第二进风口121共用一个第二进风通道，在此不再具体限定。
参照图12和图14所示，在本公开的一些实施例中，移动空调还包括中隔板600，中隔板600位于机壳100内，中隔板600和机壳100之间形成用于容纳出风壳体200的腔体，出风壳体200安装于中隔板600上，第二进风口121位于中隔板600的上方，中隔板600和下壳体120’之间限定出连通第二进风口121和换热器300的第二进风通道，使得第二进风通道的密封性较好，避免第二进风口121的进风气流在机壳100内发生窜风，进而减少第二进风通道的进风风量的损失。另外，第二进风口121通过密封的第二进风通道将补充进风气流汇入至出风壳体200内，从而提高移动空调的换热效率。
参照图14和图15所示，在本公开的一些实施例中，移动空调还包括导风器700，导风器700位于下壳体120’内，导风器700的两端分别连接中隔板600和下壳体120’上用于安装风管500的安装部122，使得移动空调与室外环境换热的风道与第二进风通道隔离且相互密封，避免两者之间发生窜风，从而影响送风机构400的送风效果。另外，参照图15所示，导风器700的外壁呈流线型，导风器700、中隔板600和下壳体120’之间形成第二进风通道，使得第二进风通道的阻力更小，进风更加顺畅，增强了换热器300的换热效率，提高了移动空调的换热效率，而且能有效降低进风噪音，使移动空调运行更加平稳、静音。
参照图10和图11所示，下壳体120’包括顶壁130’和围壁140’，围壁140’环绕于顶壁130’的左端、后端和右端设置。可以理解的是，第二进风口121位于所述围壁140’，即第二进风口121可以布置于围壁140’的左侧 壁面、右侧壁面、左右侧壁面或者后侧壁面，又或者在围壁140’的所有壁面上均有布置。第二进风口121设置于围壁140’上，可以减少风管500对第二进风口121的影响，保证第二进风口121补充风量的效果。
参照图11所示，第二进风口121包括多个均匀布置的通孔，通孔的形状并不具体限定，只要满足进风需要的孔径大小即可，多个通孔能够提升补充的风量，提升移动空调的换热效果。举例来说，第二进风口121包括一个或多个长条孔，长条孔可以沿水平方向延伸设置，或沿垂直方向延伸设置，在此不再具体限定；多个长条孔均匀布置于围壁140’上，或者阵列布置于围壁140’上，在此不再具体限定。另外，第二进风口121包括多个圆孔或者多边形孔，多个圆孔或者多边形孔均匀布置于围壁140’上。
可以理解的是，为了进一步增加进风效果，风管500一般安装于顶壁130’上，因此对上壳体110’的第一进风口111会存在一定的阻挡，从而影响出风壳体200的进风量。所以，通过将第二进风口121设置在顶壁130’且沿安装部122的周边设置，能在第一进风口111的附近位置进一步补充进风量，可以有效提高出风壳体200的进风量，而且不会与风管500进行窜风，从而提高了移动空调的换热效率。
参照图11所示，在本公开的一种实施例中，设置于顶壁130’上的第二进风口121的尺寸需要满足一定的要求，例如第二进风口121内部能够形成的最大内接圆的直径为d，所述d满足：0<d≤8mm。需要说明的是，本公开实施例的方案中，第二进风口121内部能够形成的最大内接圆的直径为d，此处最大内接圆可以理解为第二进风口121对应的每个通孔中，通孔的外轮廓轨迹能够形成的最大的内接圆。
举例来说，当第二进风口121为长条孔时，d指的是长条孔较短的一边的长度；当第二进风口121为圆孔时，d指的是圆孔的直径。当d满足上述参数要求的情况下可以避免异物从第二进风口121落入机壳100内，对移动空调的运行造成损伤，便于对下壳体120’进行清洁，而且满足安全规定的要求。
参照图15和图16所示，在本公开的一些实施例中，第一进风口111可拆卸连接有第一过滤组件150，第一过滤组件150通过卡扣151连接于上壳体110’上，卡扣151可以设有多个，多个卡扣151沿第一过滤组件150的周向设置。当然，第一过滤组件150也可以采用其他便于拆卸的方式安装于上壳体110’上，例如螺栓等方式。需要说明的是，第一过滤组件150覆盖在第一进风口111，对第一进风口111进入的空气进行过滤，避免空气对换热器300造成污染，而且还能提升送风机构400吹出的空气的质量，提升了用户体验。
参照图14和图15所示，在本公开的一些实施例中，为了避免第二进风口121的进风气流污染换热器300的表面，下壳体120’内设有第二过滤组件160’，第二过滤组件160’位于第二进风通道内，第二过滤组件160’对第二进风口121的进风气流进行过滤，避免补充进风对换热器300造成污染，而且还能提升送风机构400吹出的空气的质量，提升了用户体验。
参照图15和图16所示，在本公开的一些实施例中，第二过滤组件160’与第一过滤组件150固定连接，用户在拆出第一过滤组件150的同时可以一同拆出第二过滤组件160’，第二过滤组件160’可以和第一过滤组件150一样通过第一进风口111向上抽出，使得第二过滤组件160’的拆装更加方便，便于用户清洗。为了方便第一过滤组件150和第二过滤组件160’可以一同从上往下插入安装或拆卸抽出，第一过滤组件150的下端一般不设置与上壳体110’配合安装的卡扣151。可以理解的是，第二过滤组件160’和第一过滤组件150可以构造为一体件，例如通过一体注塑成型。第二过滤组件150通过将第一过滤组件150向下延伸形成，同样可以便于用户同时拆出第一过滤组件150和第二过滤组件160’。
具体的，参照图16所示，在本公开的一些实施例中，第一过滤组件150包括安装架152和过滤网(图中未示出)，安装架152上设置与机壳100可拆卸连接的结构，例如卡扣151等，方便拆卸清洗，用户操作更加方便。安 装架152上还形成有用于容置过滤网的凹槽(图中未示出)，过滤网可固定于凹槽内；当然，过滤网也可以通过粘接、螺接等方式固定于安装架152上，在此不再具体限定。需要说明的是，安装架152的表面设有格栅153，格栅153之间形成有格栅孔，空气通过安装架152上的格栅孔进入上壳体110’内的第一进风通道前，空气均需要经过过滤网进行过滤，过滤后的空气再进入换热器300进行换热，能有效阻隔空气中的尘埃等微粒，避免换热器300表面积聚杂质，进而影响换热器300的换热效率。
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，在所属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。
