进一步地，风道主体朝向风道前盖板的一侧还形成有第二线槽，用于放置风门的导线；风道前盖板和风道主体在第二线槽的四周形成有互相配合的凹凸结构，以封闭第二线槽。
进一步地，用于冰箱的风道***，还包括：接插件，设置于风道主体和风道前盖板之间，用于连通风机的导线和风门的导线；风道主体和风道前盖板上分别形成有容纳接插件的容纳槽。
进一步地，风道主体靠近风门和风机的位置处分别设置有风门线口和风机线口，风门线口和风机线口均贯穿风道主体；风机的导线穿过风机线口进 入第一线槽，风门的导线穿过风门线口进入第二线槽。
进一步地，风道后盖板与风道主体还限定出第三风道，第三风道与第二风道并列设置，均位于风机的上方；并且风道后盖板的侧壁上还形成有一风道开口，用于向冰箱的第二间室送风。
进一步地，用于冰箱的风道***，还包括：风道后饰板，罩扣在风道主体上，遮蔽风道后盖板和风机，并与风道主体限定出第四风道；第四风道位于风机的下方，用于向冰箱的第三间室送风；蒸发器，设置于风道后饰板的外侧，用于冷却流向风机的气流。
进一步地，风机为离心风机，离心风机的进风口与风道后饰板相对，并且风道后饰板与进风口相对的位置处设置有开口，以便于气流通过开口流入离心风机。
本发明还提供了一种冰箱，包括：箱体；以及上述任一种的用于冰箱的风道***，风道***设置于箱体的背部。
本发明的用于冰箱的风道***及冰箱，由于设置风道前盖板和风道主体在第一线槽的四周形成有互相配合的凹凸结构，利用凹凸结构对第一线槽进行封闭，从而提高了第一线槽的密封性，降低了风道***的凝露风险。
进一步地，本发明的用于冰箱的风道***及冰箱，将风机和风道后盖板设置在风道主体远离风道前盖板的一侧，并设置风道后盖板与风道主体形成与第一风道连通的第二风道。风机的导线穿过风道主体进入第一线槽内，第一线槽不与第一风道或第二风道直接接触，从而避免了第一线槽产生内外温差。此外，双层风道的设置，使冷却气流在风机的作用下依次通过第二风道、第一风道到达第一间室，降低了风道前盖板的前后温差，从而降低了风道前盖板的凝露风险。
进一步地，本发明的用于冰箱的风道***及冰箱，由于在第二风道内设置有风门，通过控制风门的开闭程度，从而对流向第一间室的风量进行控制，进而实现了对第一间室的温度控制，使第一间室实现全变温。
进一步地，本发明的用于冰箱的风道***及冰箱中，风道主体朝向风道前盖板的一侧还设置有第二线槽，用于放置风门的导线。通过设置风道主体和风道前盖板在第二线槽的四周同样形成有相互配合的凹凸结构，从而提高了第二线槽的密封性，进一步降低了风道***的凝露风险。
进一步地，本发明的用于冰箱的风道***及冰箱，由于在风道主体和风道前盖板之间设置有接插件，使风机的导线和风门的导线连接至接插件，从而避免了风门或风门的导线过短影响使用。实现了风门和风机的标准化使用，从而提高了生产效率。

以下将结合附图1-17所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。

如图1-17所示，本实施例的方案首先提供了一种用于冰箱的风道***100，一般性地可以包括：风道主体110和风道前盖板130。
其中，风道主体110上设置有风机120。风道前盖板130罩扣在风道主体110的一侧，与风道主体110限定出第一风道131，第一风道131连通至冰箱10的第一间室211。风道主体110朝向风道前盖板130的一侧形成有第一线槽111，用于放置风机的导线121。风道前盖板130和风道主体110在第一线槽111的四周形成有互相配合的凹凸结构，以封闭第一线槽111。
本实施例的方案，通过设置风道主体110和风道前盖板130在第一线槽111的四周形成有互相配合的凹凸结构，利用凹凸结构对第一线槽111进行封闭，从而提高了第一线槽111的密封性。
进一步地，本实施例的方案，通过提高第一线槽111的密封性，避免了冷却气流进入第一线槽111内，从而避免了第一线槽111内的风机的导线121过冷，进而避免了风道前盖板130在靠近第一线槽111的部分的前后温差过大，避免了风道前盖板130产生凝露或结冰，提高了用户的使用体验。
如图9所示，风道前盖板130上沿第一风道131的设置方向(即竖直方向)还可以间隔设置有多个出风口132，第一风道131内的冷却气流通过多个出风口132均匀地流向第一间室211内，从而提高了第一间室211内的温度均匀性，同时避免了风道前盖板130局部过冷产生凝露。
此外，在一些实施例中，风道前盖板130和风道主体110的周边还可以设置有互相配合的凹凸结构，以进一步提高风道***100的整体密封性，避免冷却气流向风道主体110的两侧溢散，从而降低冰箱10的箱体200的侧 壁的凝露风险。
用于冰箱的风道***100还可以包括：风道后盖板140。
其中，风道后盖板140罩扣在风道主体110的另一侧，与风道主体110限定出第二风道141。风道主体110的顶部还设置有风道连接口115，以连通第一风道131和第二风道141。风机120设置于风道主体110靠近风道后盖板140的一侧，并且风机120位于风道后盖板140的下方。
如图5-6所示，本实施例的方案中，风道前盖板130、风道主体110、风道后盖板140依次堆叠设置，第一风道131和第二风道141分别位于风道主体110的两侧，形成双层风道。第一间室211位于风道前盖板130的前方。风机120位于第二风道141的下方。风道***100内的所有冷却气流均流经风机120，但只有部分冷却气流能够在风机120的作用下，依次通过第二风道141、风道连接口115、第一风道131，最终流向位于风道前盖板130前方的第一间室211。其余冷却气流被损耗或扩散向其他方向(在一些实施例中，冰箱10内可以设置有多个间室，部分冷却气流可以流向除第一间室211外的其它间室)。
风道前盖板130的前壁面(即其朝向第一间室211的壁面)的温度主要受第一间室211的温度影响(即流至第一间室211的部分冷却气流的影响)，风道前盖板130的后壁面的温度在受到流向第一间室211的部分冷却气流的影响的同时，还可能受到其后方所有流经风机120的冷却气流的温度影响。风道前盖板130的前壁面和后壁面的温差越大，风道前盖板130的凝露风险则越高。
本实施例的方案，通过设置风道前盖板130、风道主体110、风道后盖板140依次堆叠设置，第一风道131和第二风道141分别位于风道主体110的两侧，形成双层风道，从而提高了风道***100的整体保温隔热效果。
进一步地，本实施例的方案，将风道前盖板130和风机120分别设置于风道主体110的两侧，增加了风道前盖板130与风机120之间的阻隔距离。使得冷却气流在不流经第一风道131的情况下，向风道前盖板130扩散温度的难度增大。从而减小了风道***100内的所有流经风机120的冷却气流对风道前盖板130的后壁面(即风道前盖板130朝向风机120所在的一侧的壁面)的温度影响。换言之，风道前盖板130的后壁面的温度主要受流至第一风道131的部分冷却气流的影响，从而避免了风道前盖板130的前后壁面的温差过大，避免了风道前盖板130产生凝露或结冰，提高了用户的使用体验。
在一些优选的实施例中，风道前盖板130、风道主体110以及风道后盖板140均可以被配置为泡沫板，以提高风道***100的整体保温隔热效果。可以理解的是，在另一些实施例中，风道前盖板130、风道主体110以及风 道后盖板140还可以被配置为用其它保温隔热效果较好的材料构成，具体的材料选择可以根据实际需求进行设置。
此外，本实施例的方案，将第一线槽111和风机120分别设置于风道主体110的两侧，使风机的导线121位于风道前盖板130和风道主体110的夹层中，从而提高了风机的导线121的密封性，避免风机的导线121过冷导致风道前盖板130的前后温差较大，进而降低了风道前盖板130的凝露风险。
在一些优选的实施例中，第一间室211可以被配置为全变温间室，其温度一般性地可以在5-24℃之间任意调节，风道主体110上的风道连接口115被设置为较大的尺寸，以满足第一间室211的全变温需求。双层风道和第一线槽111的结构的特别设置，提高了风道***100的保温隔热效果，降低了前风道盖板受全部流经风机120的冷却气流的温度影响，避免了前风道盖板的前后温差过大。即使第一间室211的温度较高(如20℃)时，风道前盖板130的温差也依然可以维持在一个较小的范围内，从而避免了风道前盖板130产生凝露或结冰，满足了用户对大容积的全变温间室的需求，进一步提高了用户的使用体验。
用于冰箱的风道***100还可以包括：风门150，设置于第二风道141内，用于调整流向第一间室211的风量。
本实施例的方案，通过在第二风道141内设置风门150，通过控制风门150的开闭程度，对流向第一间室211的风量进行控制，从而实现了对第一间室211的温度控制。
在一些优选的实施例中，第一间室211可以被设置为全变温间室，通过控制风门150的开闭实现全变温功能。在第一间室211内或第一风道131通向第一间室211的出风口132处还可以设置有温度传感器，对第一间室211内的温度进行检测。风门150被配置为根据检测温度调整其开闭程度，对流向第一间室211的冷却气流量进行控制，从而使第一间室211达到用户需求的温度。
风道主体110朝向风道前盖板130的一侧还形成有第二线槽112，用于放置风门的导线151。风道前盖板130和风道主体110在第二线槽112的四周形成有互相配合的凹凸结构，以封闭第二线槽112。
本实施例的方案，通过设置风道主体110和风道前盖板130在第二线槽112的四周同样形成有相互配合的凹凸结构，从而提高了第二线槽112的密封性，进一步降低了风道***100的凝露风险。
进一步地，本实施例的方案，通过提高第二线槽112的密封性，避免了冷却气流进入第二线槽112内，从而避免了第二线槽112内的风门的导线151过冷，进而避免了风道前盖板130在靠近第二线槽112的部分的前后温差过 大，进一步降低了风道前盖板130产生凝露或结冰的风险，提高了用户的使用体验。
用于冰箱的风道***100还可以包括：接插件160，设置于风道主体110和风道前盖板130之间，用于连通风机的导线121和风门的导线151。风道主体110和风道前盖板130上分别形成有容纳接插件160的容纳槽114。
如图6和图11所示，风道主体110和风道前盖板130上分别形成有一个容纳槽114，风道前盖板130扣合在风道主体110上时，这两个容纳槽114对接在一起，形成一个用于放置接插件160的容纳空间。风道主体110和风道前盖板130在容纳槽114的四周同样形成有互相配合的凹凸结构，以提高容纳槽114的密封性，进一步降低风道前盖板130的凝露风险。第一线槽111和第二线槽112分别连通至风道主体110上的容纳槽114，以使风机的导线121和风门的导线151连接至接插件160上。
本实施例的方案，通过在风道主体110和风道前盖板130之间设置有接插件160，使风机的导线121和风门的导线151连接至接插件160，从而避免了风机的导线121或风门的导线151过短影响使用。实现了风门150和风机120的标准化使用，从而提高了冰箱的风道***100的生产效率。
如图12和图14所示，风道主体110朝向风道前盖板130的一侧还形成有第三线槽113，用于放置接插件的导线161。第三线槽113一端连通至容纳槽114，一端连通至风道主体110的顶端。
风道主体110和风道前盖板130在第三线槽113的四周同样形成有互相配合的凹凸结构，以提高第三线槽113的密封性，减小第三线槽113对风道前盖板130的温度影响，降低风道前盖板130的凝露风险。
在一些优选的实施例中，为了进一步提高第三线槽113的密封性，可以将第三线槽113设置为Z字形。即第三线槽113在靠近风道主体110的顶端的部分槽段被设置为沿水平方向向前延伸一段距离后，再沿竖直方向向上延伸至风道主体110的顶端。
风道主体110靠近风门150和风机120的位置处分别设置有风门线口116和风机线口117，风门线口116和风机线口117均贯穿风道主体110。风机的导线121穿过风机线口117进入第一线槽111，风门的导线151穿过风门线口116进入第二线槽112。
本实施例的方案，通过在风道主体110上设置风机线口117和风门线口116，使风机的导线121和风门的导线151分别穿过风道主体110进入风道主体110的另一侧形成的第一线槽111和第二线槽112内，从而提高了风机的导线121和风门的导线151的密封效果。并且，第一线槽111和第二线槽112不与第一风道131或第二风道141直接接触，进一步降低了冷却气流进 入第一线槽111或第二线槽112内的可能性，从而避免了风机的导线121和风门的导线151过冷，降低了风道前盖板130的凝露风险。
在一些优选的实施例中，在风机线口117和风门线口116处还可以设置有密封件，如密封圈等，从而进一步提高第一线槽111和第二线槽112的密封效果。
风道后盖板140与风道主体110还限定出第三风道142，第三风道142与第二风道141并列设置，均位于风机120的上方。并且风道后盖板140的侧壁上还形成有一风道开口143，用于向冰箱10的第二间室221送风。
在一些优选的实施例中，第一间室211被配置为全变温间室，第二间室221被配置为冷藏间室。因此，第二风道141的横截面积被配置为大于第三风道142的横截面积，以提高第二风道141的单位时间内的最大送风量，提高第一间室211的降温速度，满足第一间室211的全变温需求。
用于冰箱的风道***100还可以包括：风道后饰板170和蒸发器180。
风道后饰板170罩扣在风道主体110上，遮蔽风道后盖板140和风机120，并与风道主体110限定出第四风道171。第四风道171位于风机120的下方，用于向冰箱10的第三间室212送风。蒸发器180设置于风道后饰板170的外侧，用于冷却流向风机120的气流。
本实施例的方案，通过设置第一风道131、第二风道141、第三风道142和第四风道171，使冷却气流分别流向三个不同的独立间室，从而足了用户对多个独立间室的需求。此外，三个间室可以被配置为不同的储藏温度，从而同时满足用户对不同温度的储藏环境的需求，进一步提高了用户的使用体验。
如图2-4所示，风道后盖板140的风道开口143朝向第二间室221设置，风道后饰板170在与风道后盖板140的风道开口143相对应的位置处相应设置有缺口173，使第三风道142内的冷却气流能够向第二间室221的方向顺利流动。相应地，第二间室221的侧壁上设置有风口(图中未示出)，风口与风道后盖板140上的风道开口143连通，以使第三风道142内的冷却气流流至第二间室221。
风机120为离心风机120，离心风机120的进风口122与风道后饰板170相对，并且风道后饰板170与进风口122相对的位置处设置有开口172，以便于气流通过开口172流入离心风机120。
本实施例的方案中，风道***100为单蒸发器***，通过设置离心风机120，使得流经蒸发器180的冷却气流在离心风机120的作用下，分别流向离心风机120上方的第二风道141、第三风道142，以及离心风机120下方的第四风道171，从而实现了三个间室的风路的独立控制。此外，将风道系 统100设置为单蒸发器***，不仅所占空间小，而且生产成本低。
如图2-3所示，风道主体110的下方一般性地还可以设置有风道连接组件190，风道连接组件190与第四风道171连通，将第四风道171内的冷却气流送至第三间室212内。
本实施例的方案还提供了一种冰箱10，该冰箱10包括：箱体200；以及上述的任意一种的用于冰箱的风道***100。其中，该风道***100设置于箱体200的背部。
如图1所示，冰箱10一般性地可以包括两个并列设置的内胆，两个内胆限定出三个间室。其中，位于冰箱10左侧的第一内胆210限定出竖直分布的第一间室211和第三间室212，并且第三间室212位于第一间室211的竖直下方。位于冰箱10右侧的第二内胆220限定出第二间室221。
在一些优选的实施例中，与风道前盖板130直接相对的第一间室211被优选地设置为全变温间室，由于特别设置的风道***100降低了第一间室211的后壁面(即风道前盖板130)的凝露和结冰风险，从而满足了用户对于大容积的全变温室的需求，提高了用户的使用体验。容积最大的第二间室221被优选地设置为冷藏室，以满足用户的大冷藏空间的需求。与风道截面积最大的第四风道171连通的第三间室212被优选地设置为冷冻室，以满足用户的冷冻需求。
在一些实施例中，风道前盖板130的前侧还可以设置有风道前饰板133，罩扣在风道前盖板130上，进一步降低第一间室211的凝露风险的同时，提高冰箱10的第一间室211的内部的美观性。
本实施例的方案，通过在风道主体110和风道前盖板130上与第一线槽111、第二线槽112以及第三线槽113相对应的位置处设置相互配合的凹凸结构，从而提高了风道主体110和风道前盖板130的密封性，同时提高了第一线槽111、第二线槽112、第三线槽113的密封效果，避免了第一线槽111、第二线槽112以及第三线槽113线内的导线过冷，从而避免了风道前盖板130的局部温差较大，进而降低了风道***100的凝露风险。
进一步地，本实施例的方案，通过设置双层风道，增加了风道盖板的数量和厚度，从而提高了风道***100的整体保温隔热效果，进一步地降低了风道前盖板130的凝露风险，保障了冰箱10的正常使用，提高了用户的使用体验。
此外，本实施例的方案，将与风道前盖板130相对的第一间室211被配置为全变温室，通过对风道***100的结构进行特别设置，从而在满足用户对于大容积全变温间室的需求的同时，降低了全变温间室内的凝露或结冰风险，进一步提高了用户的使用体验。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
