如图1所示，本发明提供一种滚筒洗衣机，包括设有衣物投放口13的外壳1和设于外壳1内的内筒3，外壳1上设开闭衣物投放口13的门体14，门体14上设第一风道121，外壳1内设第二风道122，外壳1上设外壳通风口151，第一风道121、外壳通风口151和第二风道122可形成烘干风道12。
本发明的实施例中，通过将门体14上的第一风道121、外壳1上的外壳通风口151和外壳上的第二风道122形成烘干风道12，能够使得形成烘干风道12的第二风道122处于外壳1的外部，减少风道对内筒3前侧与外壳1之间空间的占用，从而增大内筒3的容量。
内筒3可为有孔内筒或无孔内筒，内筒3为有孔内筒时，外筒2为盛水筒，内筒3为无孔内筒时，内筒3为盛水筒；外壳1具有前面板15，外壳通风口151和衣物投放口13设于外壳的前面板15上；
内筒3具有内筒进风口36和内筒出风口37，烘干风道12分别与内通进风口和 内筒出风口37连通，实现内筒内部风的循环，重复利用风的热量；
如图1所示，门体14包括第一部分和/或第二部分，第一部分的径向尺寸大于衣物投放口13的径向尺寸，第二部分的径向尺寸小于衣物投放口13的径向尺寸，第一部分在关门后与前面板15贴合设置，第二部分在关门后经衣物投放口13嵌入外壳1内，具体地，第二风道122设于第一部分上，而非外壳1内，能够减少外壳1内的管路数，以及减少烘干风道12对内筒3前侧和外壳1之间空间的占用。
门体14在关闭衣物投放口13时，第一风道121、第二风道122和外壳通风口151能够形成烘干风道12，烘干风道12向内筒3内供热风，用于对内筒3内衣物进行干燥；门体14在打开衣物投放口13时，第一风道121、第二风道122和外壳通风口151不能够形成烘干风道12，也就是第一风道121与外壳通风口151和第二风道122不相通。
如图1所示，本发明的实施例中，门体14的内部中空形成竖直延伸的第一风道121，第一风道121的进风口设于门体14内侧的顶部，外壳通风口151与第一风道121的进风口的位置对应、且可与第一风道121的进风口重叠、连通。
本发明的实施例中，对于第一风道121而言，第一风道121在门体14内竖直延伸，第一风道121进风口设于门体14内侧，使得第一风道121的进风口在门体14关闭衣物投放口13时能够与外壳通风口151对应，从而才能与外壳通风口151连通；外筒2通风口的延伸尺寸与第一风道121的进风口的延伸尺寸相同，在门体14关闭衣物投放口13时，外筒2通风口与第一风道121的进风口重叠，减少热风从外筒2通风口与第一风道121的进风口之间的间隙泄漏；由于热风一般会在上方流动，因此，第一风道121的进风口设于门体14的顶部，便于热风从第一风道121的进风口进入第一风道121内；
如图2所示，进一步地，第一风道121进风口的外周设一圈定位凹槽19，定位凹槽19内设一圈密封圈17；在第一风道121进风口的外周设密封圈17，密封圈17在门体14关闭衣物投放口13时与外壳前面板15相抵，减少热风从第一风道121进风口与外壳通风口151之间泄露；
为了增加密封圈17的稳定性，避免密封圈17错位移动，提高第一风道121进风口与外壳通风口151之间的密封性，因此，在门体14内侧设定位凹槽19，定位凹槽19内嵌入有密封圈17，至少部分密封圈17外露于定位凹槽19，定位凹槽19的槽口在门体14关闭衣物投放口13时朝向外壳前面板15，外露于定位凹槽19的密封圈17与外壳前面板15相抵，定位凹槽19具体地设置在第一风道121进风口的外周。
如图1所示，本发明的实施例中，第二风道122包括在内筒3顶部水平延伸的第一子风道1221、和第二子风道1222，第一子风道1221的出风口延伸至内筒3的前侧、且高于外壳通风口151设置，第二子风道1222倾斜设置在内筒3前侧与外壳1之间的空间内、且分别与第一子风道1221的出风口和外壳通风口151连通。
在本发明的实施例中，第二风道122包括第一子风道1221和第二子风道1222，第一子风道1221在内筒3的顶部水平延伸，从内筒3的后侧延伸至内筒3的前侧，第一子风道1221充分利用内筒3顶部与外壳1之间的空间，第一子风道1221的出风口设于内筒3的后侧，第一子风道1221的进风口设于内筒3的前侧，第一子风道1221内设有加热气体的加热装置和为热风流动提供动力的风机；
第一子风道1221的出风口与外壳通风口151和第一风道121的进风口之间具有高度差，第一子风道1221的出风口高于外壳通风口151和第一风道121进风口设置，因此，为了实现第一子风道1221的出风口与外壳通风口151之间的连通、且减少第二子风道1222占用内筒3前侧与外壳1之间的空间，将第二子风道1222 倾斜地设置在内筒3前侧与外壳1之间的空间内，第二子风道1222的出风口与外壳通风口151连通，第二子风道1222的进风口与第一子风道1221的出风口连通，若第二子风道1222并未倾斜设置，而是采用先竖直后水平的排布，则会使得第二子风道1222的设置占用更多的空间。
如图1所示，本发明的实施例中，还包括设于内筒3外的外筒2，外筒2包括筒体25和与筒体25同轴设置的环形凸出部26，环形凸出部26的内周围成外筒筒口241，环形凸出部26的径向尺寸小于筒体25的径向尺寸，第一子风道1221在外筒2的顶部延伸，第一子风道1221的出风口延伸至筒体25的前端与环形凸出部26的前端之间，外壳通风口151设于筒体25的顶部与外筒筒口241的顶部之间。
本发明的实施例中，滚筒洗衣机还包括外筒2，外筒2设于外壳1内，内筒设于内筒3内，外筒2与内筒3同轴设置，外筒筒口241、内筒筒口38与衣物投放口13同轴设置；

本发明的实施例中，在衣物投放口13与外筒筒口241之间设有环形窗垫16，环形窗垫16能够阻挡异物进入外筒2与外壳1之间的空间内，由于外壳通风口高于环形窗垫16与衣物投放口13的连接处，且衣物投放口13的径向尺寸大于外筒筒口241的径向尺寸，环形窗垫16从后向前径向尺寸逐渐增大，因此，可以得出第二子风道1222设于环形窗垫16的外周侧，使得环形窗垫16能够阻挡第二子风道1222内的热量传递至其他与第二子风道1222相隔较远的地方。
本发明的实施例中，第一风道的出风口1211设于门体14的内侧、作为烘干风道12的出风口，第一风道的出风口1211与内筒筒口38的位置对应、且可经衣物投放口13与内筒筒口38连通。

如图3-5所示，本发明的实施例中，阻挡结构4包括外筒内周壁径向凸伸一圈形成的第一环形挡筋，和/或内筒外周壁径向凸伸一圈形成的第二环形挡筋。
本发明的实施例中，阻挡结构4包括第一环形挡筋，第一环形挡筋由外筒内周壁径向凸伸一圈形成，第一环形挡筋可与内筒外周壁相抵，或者可与内筒外周壁之间具有间隙，实现第一环形挡筋对水进行阻挡；
在另外一个实施例中，阻挡结构4包括第二环形挡筋，第二环形挡筋由内筒外周壁径向凸伸一圈形成，第二环形挡筋可与外筒内周壁相抵，或者可与外筒内周壁之间具有间隙，实现第二环形挡筋对水进行阻挡；

如图4和图5所示，进一步地，第一环形挡筋内周侧与内筒外周壁之间具有第一间隙，第二环形挡筋封盖第一间隙，第二环形挡筋外周侧与外筒内周壁之间具有第二间隙，第一环形挡筋封盖第二间隙，通过第一环形挡筋与第二环形挡筋的配合实现对水进行阻挡；其中，第一环形挡筋可与第二环形挡筋在轴向方向上相抵，或者，第一环形挡筋与第二环形挡筋在轴向方向上间隔设置。
更进一步地，第一环形挡筋凸伸至超出第二环形挡筋的外周侧，第二环形挡筋凸伸至超出第一环形挡筋的内周侧，第一环形挡筋与第二环形挡筋沿轴向有间距地设置。
洗衣机长时间使用后，内筒与外筒2之间会存在污垢，上述污垢包括污水污垢和其他污垢，为了后续便于对外筒2的排水区21和非排水区进行污垢处理，防止外筒的排水区21和非排水区为不能处理的死角区，于是，将第一环形挡筋与内筒外周壁有间隙的设置，第二环形挡筋与外筒内周壁有间隙的设置，第一环形挡筋与第二环形挡筋沿轴向有间距地设置，使得外筒2的排水区21和非排水区能够经间隙进行污垢处理；
阻挡结构4包括第一环形挡筋和第二环形挡筋，第一环形挡筋和第二环形挡筋能够对水流起到双重阻挡作用，加强对排水区21内水流的阻挡强度；其中，第一环形挡筋和第二环形挡筋沿轴向设置，第一环形挡筋设置在第二环形挡筋的前端，或者，第一环形挡筋和第二环形挡筋沿轴向设置，第二环形挡筋设置在第一环形挡筋的前端；

第一环形挡筋凸伸至超出第二环形挡筋的外周侧，第二环形挡筋凸伸至超出第一环形挡筋的内周侧，使得第二环形挡筋径向延伸的尺寸大于第一间隙径向延伸的尺寸，第一环形挡筋径向延伸的尺寸大于第二间隙径向延伸的尺寸，使得第一环形挡筋和第二环形挡筋能够有效地水阻挡。
如图3-5所示，在上述实施例的基础上，具体地，外筒2包括由外筒筒壁211构成的排水区21和外筒两端壁构成的两个非排水区，两个非排水区分别设外筒筒口241和通风口242，外筒筒口241和通风口242作为开口24，阻挡结构4包括靠近外筒筒口241的前第一环形挡筋41和前第二环形挡筋43和靠近通风口242的后第一环形挡筋42和后第二环形挡筋44；
前第一环形挡筋41与内筒外周壁之间具有前第一间隙5，前第二环形挡筋43与外筒内周壁之间具有前第二间隙7，后第一环形挡筋42与内筒外周壁之间具有后第一间隙6，后第二环形挡筋44与外筒内周壁之间具有后第二间隙8。
两个非排水区分别为前非排水区22和后非排水区23，前非排水区22为外筒前端壁221，前非排水区22设外筒筒口241，外筒筒口241作为开口24，后非排水区23为外筒后端壁231，后非排水区23设通风口242，用于连接烘干风道，通风口242作为开口24，为了防止水从外筒筒口241和通风口242泄漏，因此，在靠近外筒筒口241的外筒筒壁211上设前第一环形挡筋41和前第二环形挡筋43，在靠近通风口242的外筒筒壁211上设后第一环形挡筋42和后第二环形挡筋44。并且，由于通风口242连接烘干管道，为了降低热风串入内外筒之间，导致热效率降低，后第一环形挡筋和后第二环形挡筋还具有阻挡热风更多进入排水区的作用。
如图3所示，进一步地，外筒筒壁211沿轴向呈阶梯状，外筒筒壁211包括前筒壁2111和后筒壁2112，后筒壁2112相对前筒壁2111向内凸伸，前第一环形挡筋41设于前筒壁2111的前端，后第一环形挡筋42设于后筒壁2112上、且靠近前 筒壁2111的后端，第一环形挡筋的尺寸由外向内逐渐减小。
第一环形挡筋的尺寸由外向内逐渐减小，使得第一环形挡筋具有一定的倾斜度，当少部分水由排水区21经第一间隙流入至非排水区的过程中，由于第一环形挡筋具有一定的倾斜度，因此，能够避免水积存在第一环形挡筋上。
本发明的实施例中，第一环形挡筋的外周侧设缺口，缺口与外筒内周壁围成轴向延伸的残水孔，残水孔连通排水区21和非排水区，径向卷边向外筒内周壁凸伸至不超出与外筒内周壁相对的缺口的一侧。

进入前非排水区22的水可经前残水孔9回流至排水区内，进入后非排水区23的水可经后残水孔10回流至排水区21内，残水孔的增设能够避免非排水区积存过多的水；
前缺口与外筒内周壁围成前残水孔9，后缺口与外筒内周壁围成后残水孔10，使得前残水孔9和后残水孔10处于最低的位置，使得水能够比较容易地经残水孔回流至排水区21。
外筒的后筒壁2112相对前筒壁2111向内凸伸，后筒壁2112高于前筒壁2111设置，使得后筒壁2112与前筒壁2111之间具有高度差，后第一环形挡筋42设于后筒壁2112的前端，使得水从后筒壁2112的高位置经后残水孔10流入前筒壁2111的低位置，加快水的回流。
径向卷边向外筒内周壁凸伸至不超出与外筒内周壁相对的缺口的一侧，使得径向卷边不影响对水回流的残水孔的大小。
本发明的实施例中，内筒包括端部开口24的筒体和封堵筒体端部开口24的 法兰，法兰的外周向外筒内周壁径向凸伸形成包裹第二环形挡筋的径向卷边，径向卷边的外周侧与外筒内周壁之间具有第二间隙。
本发明的实施例中，法兰的外周设径向卷边，径向卷边对第二环形挡筋进行包裹，增加法兰与内筒之间的装配强度，同时提高第二环形挡筋的结构强度，增加第二环形挡筋对水流进行阻挡的强度；
如图3-5所示，具体地，内筒包括筒体和筒体两端分别设有的封堵前端开口24的前法兰32和封堵后端开口24的后法兰33，前法兰32设有前径向卷边34，后法兰33设有后径向卷边35，前径向卷边34设于前第一环形挡筋41的前端，后径向卷边35设于后第一环形挡筋42的后端。
内筒的筒体两端分别开口24，分别为前端开口24和后端开口24，前法兰32封堵前端开口24，后法兰33封堵后端开口24，前法兰32和后法兰33为圆盘状，筒体为圆筒状，前法兰32、后法兰33与筒体同轴设置；
如图4所示，对于前法兰32和前第二环形筋而言，前法兰32的外周先向前轴向延伸形成前第一翻边，前第一翻边与内筒的内周壁相抵，前第一翻边的前端向外筒2再径向延伸形成前第二翻边，前第二翻边靠近外筒内周壁的一端再向后轴向延伸形成前第三翻边，前第三翻边再向内筒径向延伸形成前第四翻边，前第四翻边靠近内筒的一端再向后轴向延伸形成前第五翻边，前第五翻边与内筒外周壁相抵，前第二翻边、前第三翻边和前第四翻边形成前径向卷边34；前第二翻边、前第三翻边和前第四翻边分别与对应的前第二环形挡筋43的侧边相抵，实现对前第二环形挡筋43的包裹。前第三翻边为圆弧状，前第三翻边向外筒2凸伸，减少水经过该位置时出现湍急的程度，避免水溅。
如图5所示，对于后法兰33与后第二环形筋而言，后法兰33的外周先向后轴向延伸形成后第一翻边，后第一翻边与内筒的内周壁相抵，后第一翻边的后端 向外筒2再径向延伸形成后第二翻边，后第二翻边靠近外筒内周壁的一端再向前轴向延伸形成后第三翻边，后第三翻边再向内筒径向延伸形成后第四翻边，后第四翻边靠近内筒的一端再向前轴向延伸形成后第五翻边，后第五翻边与内筒外周壁相抵，后第二翻边、后第三翻边和后第四翻边形成后径向卷边35；后第二翻边、后第三翻边和后第四翻边分别与对应的后第二环形挡筋44的侧边相抵，实现对后第二环形挡筋44的包裹。后第三翻边为圆弧状，后第三翻边向外筒2凸伸，减少水经过该位置时出现湍急的程度，避免水溅。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，上述实施例中的实施方案也可以进一步组合或者替换，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
