本公开所提供的干衣机，包括：滚筒，设置有除湿口，以排出所述滚筒内的部分低温高湿风；风道，所述风道的进风端和出风端分别与所述滚筒的两端连通；蒸发器、冷凝器以及加热引风组件，顺次沿所述风道的进风端向所述出风端的方向设置在所述风道内，所述加热引风组件包括加热器以及风机，所述冷凝器和所述加热引风组件之间的风道上设置有新风入口，室外新风通过所述新风入口引入到所述风道内，同所述风道内的工作空气混合后，经所述加热引风组件加热后引入到所述滚筒内，以烘干衣物。
本申请所提供的干衣机，由于该干衣机的引风系统中，与滚筒的两端连通的风道上设置有新风入口，且该新风入口设置在冷凝器和加热引风组件之间的风道上，这样干衣机在使用时，空气新风可通过新风入口进入到干衣机的风道中，同风道内的工作空气混合后，经加热引风组件加热形成高温低湿风，高温低湿风引入到滚筒内，引入到滚筒内的高温低湿风带走滚筒内的衣物的水分，形成低温高湿风。由于滚筒设置有除湿口，滚筒内的低温高湿风的一部分低温高湿风，可通过滚筒的除湿口排至环境中，以带走水分，另一部分低温高湿风引入到风道中，形成工作空气，经蒸发器冷凝出水以及冷凝器加热后，同从新风入口补充到干衣机的风道中的新风汇集，再次被加热引风组件加热形成循环风，以达到对干衣机的滚筒内的衣物干衣的目的。
本公开由于通过在与滚筒的两端连通的风道上设置有补充环境新风的新风入口，可补充引入至干衣机的滚筒内的循环风的风量和温度，另外，可通过设置在滚筒上设置的除湿口将部分低温高湿风排至环境中，这样从滚筒引入到风道的低温高湿风的含水量减少，该部分低温高湿风再经过蒸发器冷凝出水以及冷凝器加热后，同从新风入口补充到干衣机的风道中的新风汇集，再次被加热引风组件加热形成循环风，引入到滚筒内的循环风可具有更多的风量和更高的温度，从而可提高干衣效率，降低干衣时间，具有很好的实用价值。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的 前提下，还可以根据这些附图获得其他的附图。
图1示出了依据本公开一个实施例的干衣机的结构示意图；
图2示出了申请人研发过程中加热器在干衣机上的一种布置示意图；
图3示出了图2所示的干衣机的工作原理示意图；
图4示出了依据本公开一些实施例的干衣机的结构示意图；
图5示出了图4所示的干衣机的引风原理示意图；
图6示出了依据本公开另一些实施例的干衣机的结构示意图；
图7示出了图6所示的干衣机的引风原理示意图。
具体实施方式
为了缩短干衣机的干衣时间，同时使干衣机更加节能，现有市场提出热泵+加热器辅热这种双热源干衣方式，其可以采用两种模式运行：纯热泵模式，更加节能，风温相对均匀，但是热量较少，因此干衣时间比较长；热泵+加热器辅热形式，通过加热器补充了热源，因此干衣时间能够有效降低。
图1示出了依据本公开一个实施例的干衣机的结构示意图，图2示出了申请人研发过程中加热器在干衣机上的一种布置示意图；图3示出了图2所示的干衣机的工作原理示意图。结合图1-图3，加热器100设置在蜗壳200中的风机600的出口处，干衣机的风道1000的进风端和出风端分别和滚筒300的两端连通，蒸发器400、冷凝器500、风机600、加热器100沿风道1000的进风端向出风端的方向依次设置在风道1000内，即构成了干衣机的引风系统，风机600将冷凝器500加热的空气引入到蜗壳200内，通过加热器100加热后，引入到滚筒300内以干燥衣物，通过滚筒 300后的湿空气进一步到达蒸发器400，蒸发器400将从滚筒300出来的湿热空气变成干燥低温空气，湿气变成冷凝水排出，低温干燥空气通过冷凝器500再次加热，即完成了一次风道循环。
由于加热器100设置在蜗壳200中的风机600的出口处，会导致蜗壳200的蜗舌附近出风不均匀，导致风速和温度加热不均匀，进入滚筒300内的风速和温度均不均匀高温风的，这种不均匀，在一定程度上没有能够充分降低干衣时间，同时，导致衣物烘干缩水时间存在差异，褶皱现象严重。
基于上述分析，本公开提供了一种干衣机，旨在至少一定程度上解决干衣机在使用时存在的干衣时间长，衣物受热不均匀导致褶皱现象的技术问题。
图4示出了依据本公开一些实施例的干衣机的结构示意图。结合图1以及图4，该干衣机主要包括滚筒300、蒸发器400、冷凝器500、加热器100以及风机600。
结合图1，滚筒300是可转动设置的，滚筒300设置有用于装载衣物的容纳腔，干衣机在使用时，转动的滚筒300可提高装载在容纳腔内的衣物的干衣效率。
结合图1以及4，风道1000具有进风端和出风端，风道1000的进风端和出风端分别和滚筒300的两端连通，蒸发器400、冷凝器500、加热器100以及风机600顺次沿风道1000的进风端向出风端的方向设置在风道1000内，且，蒸发器400、冷凝器500、加热器100并列间隔设置。
图5示出了图4所示的干衣机的引风原理示意图。结合图5，由于该干衣机的风道1000的进风端和出风端分别和滚筒300的两端连通，蒸发 器400、冷凝器500、加热器100以及风机600沿风道的进风端向出风端的方向依次设置在风道1000内，风机600将冷凝器500以及加热器100加热的空气引入滚筒300内以干燥衣物，通过滚筒300后的湿空气进一步到达蒸发器400，蒸发器400将从滚筒300出来的湿热空气变成干燥低温空气，湿气变成冷凝水排出，低温干燥空气通过冷凝器500和加热器100再次加热，即完成了一次风道循环。
本公开所提供的干衣机，由于其引风系统是通过冷凝器500和加热器100依次对干燥空气进行加热，可通过加热器100补充热源，干衣时间能够有效降低；另外，由于蒸发器400、冷凝器500、加热器100并列间隔设置，从滚筒300出来的湿空气可平行地依次经过蒸发器400、冷凝器500以及加热器600形成风速均匀的高温风，且出风温度均匀，进入滚筒300之后的温度以及速度均匀的高温风，可保证滚筒300内的衣物缩水程度一致，避免衣物局部过烘引起的褶皱、干衣慢的情况，具有很好的实用价值。
滚筒300的两端分别为入风口以及出风口，风道1000的进风端和滚筒300的出风口连通，风道1000的出风端和滚筒300的入风口连通。
结合图4，该干衣机还包括底座700，风道1000设置在底座700上，滚筒300可转动地设置在底座700的顶部上方。
结合图4，底座700包括底板701、侧板702以及盖板(图中未画出)，两个侧板702相对设置在底板701上，盖板盖设在两个侧板701上，底板701、两个侧板702以及盖板可围成一个两端敞口的风道。
结合图1以及图4，该干衣机还包括前支撑800，前支撑800用于支撑滚筒300的前端，前支撑800处设置有过滤腔801，该过滤腔801 的顶部敞口，过滤腔801内设置有过滤件900，过滤腔801的内侧设置有引风口802，风道1000的进风端和该引风口802连通，通过滚筒300后的湿空气先进入到过滤腔801中，通过过滤件900将湿空气中的毛屑过滤，过滤后的湿空气到达蒸发器400，蒸发器400将湿热空气变成干燥低温空气，湿气变成冷凝水排出，低温干燥空气通过冷凝器500和加热器100再次加热，形成高温干燥空气。
结合图1以及图4，该干衣机还包括蜗壳200，蜗壳200设置在滚筒300的后端，蜗壳200设置有进风口、容纳腔以及出风口，蜗壳200的进风口和风道的出风端连接，风机600设置在蜗壳200的容纳腔中，蜗壳200的出风口和滚筒300的后端连通，风机600将经过冷凝器500和加热器100再次加热形成的高温干燥空气通过蜗壳200引入到滚筒300内，以对滚筒300内装载的衣物进行干衣。
由于对低温干燥空气再次加热的加热器100并未设置在蜗壳200中的风机600的出口处，从而可避免蜗壳200的蜗舌附近出风不均匀，导致风速和温度加热不均匀的技术问题，以改善干衣时间以及衣物的褶皱现象。
结合图4，滚筒300设置在底座700的上方，蒸发器400、冷凝器500以及加热器100位于和滚筒300的中心轴相平行的同一直线上，即从滚筒300的出风口引入的湿空气可在较短的路径内引入到蜗壳200中，避免湿空气发生紊流的现象。
优选地，加热器100可以为电加热器，当然，其也可以为其他类型的加热器，在此不做限制。
另外，将加热器100布局在底座700上，可通过在底座700创造加 热空间，通过减少蒸发器400和冷凝器500的数量实现，具体实现技术可采用通过匹配小热泵系统，减少蒸发器和冷凝器体积，也可通过强化加热器100的性能，减少蒸发器400和冷凝器500体积的方式来实现，对此不作限制。
本公开所提供的干衣机，其通过冷凝器500和加热器100依次对干燥空气进行加热，且蒸发器400、冷凝器500、加热器100位于同一直线上，可提高热风的风速和风温的均匀性，以降低干衣时间，同时减少衣物受热不均匀导致的褶皱现象。
还有，相比于将加热器100安装在蜗壳200中的方案，本公开将加热器100安装的底座700上，其安装也更为简单方便。
申请人在上述干衣机的基础上继续研究，发现现有技术中的干衣机在使用时存在干衣时间长的技术问题，基于此，本公开对此进行改进。
图6示出了依据本公开另一些实施例的干衣机的结构示意图。结合图6，该干衣机包括滚筒300、风道1000、蒸发器400、冷凝器500以及加热引风组件，其中，滚筒300设置有用于排出部分湿气的除湿口301，风道1000具有进风端和出风端，风道1000的进风端和出风端分别与滚筒300的两端连通，加热引风组件包括风机600以及加热器100，蒸发器400、冷凝器500以及加热引风组件顺次沿风道100的进风端向出风端的方向设置在风道1000内，冷凝器500和加热引风组件之间的风道1000上设置有新风入口1200，以用于向风道1000内引入环境新风。
本公开所提供的干衣机，由于该干衣机的引风系统中与滚筒300的两端连通的风道上设置有新风入口1200，且该新风入口1200设置在冷凝器500和加热引风组件之间的风道上，这样干衣机在使用时，新风可 通过新风入口1200进入到干衣机的风道1000中，同风道1000中的工作空气混合后，经加热引风组件加热形成高温低湿风，高温低湿风引入到滚筒300内，引入到滚筒300内的高温低湿风带走滚筒300内的衣物的水分，形成低温高湿风。
由于滚筒300设置有除湿口301，滚筒300内的低温高湿风的一部分低温高湿风，可通过滚筒300的除湿口301排至环境中，以带走水分，另一部分低温高湿风引入到风道1000中，形成工作空气，经蒸发器400冷凝出水以及冷凝器500加热后，同从新风入口补充到干衣机的风道1000中的环境新风汇集，再次被加热引风组件加热形成循环风，以达到对干衣机的滚筒300内的衣物干衣的目的。
本公开由于通过在与滚筒300的两端连通的风道上设置有补充新风的新风入口1200，可补充引入至干衣机的滚筒300内的循环风的风量和温度，另外，可通过设置在滚筒300上除湿口301将部分低温高湿风排至环境中，这样从滚筒300引入到风道的低温高湿风的含水量减少，该部分低温高湿风再经过蒸发器400冷凝出水以及冷凝器500加热后，同从新风入口1200补充到干衣机的风道中的新风汇集，再次被加热引风组件加热形成循环风，引入到滚筒300内的循环风可具有更多的风量和更高的温度，从而可提高干衣效率，降低干衣时间，具有很好的实用价值。
结合图6，加热引风组件中的加热器100和风机600顺次沿风道1000的进风端向出风端的方向设置，即设置有该加热引风组件的风道1000可以为上述风道，加热器100布置在风机600的上游，以进一步降低干衣机的干衣时间，并改善干衣质量。
结合图6，新风入口1200设置在冷凝器400和加热器100之间的风 道1000上，即该新风入口1200可以设置在第一风段1000上，从新风入口1200补充的新风通过风机600引入到加热器100加热处理后形成高温低湿风，高温低湿风再通过蜗壳即引入到干衣机的滚筒300内进行干衣。
图7示出了图6所示的干衣机的引风原理示意图。结合图7，加热引风组件中的风机600和加热器100顺次沿风道的进风端向出风端的方向设置，即加热器100设置在风机600的下游，也可进一步降低干衣机的干衣时间。此种情况下，新风入口1200设置在蜗壳200上，从新风入口1200补充的新风通过风机600引入到加热器100加热处理后形成高温低湿风，高温低湿风再通过蜗壳即引入到干衣机的滚筒300内进行干衣。
结合图6以及图7，除湿口301可设置在滚筒300和风道1000的进风端连通的端部上，即除湿口301设置在滚筒300的出风端上，这样可以利用风道的气流方向将湿气排出，具有较好的湿气排出效率，并可防止湿气进入干衣机的壳体内。
当然，除湿口301还可以设置在滚筒300的周面上，对此不作具体限制。
结合图6以及图7，该干衣机还包括设置在新风入口1200上的第一控制阀1300，通过控制第一控制阀1300的通断，可实现新风入口的开闭，进而可实现不同的干衣模式，具体指令可参考下文描述。
结合图6以及图7，该干衣机还包括设置在除湿口301上的第二控制阀1100，通过控制第二控制阀1100的通断，可实现新风入口的开闭，进而可实现不同的干衣模式，具体指令可参考下文描述。
第一控制阀1300和第二控制阀1100均可以为电磁阀，其可接受外界指令，自动开启或关闭。当然，其也可以为其他类型的控制阀，对此 不作具体限制。
本公开所提供的干衣机的的干衣模式可以包括快速模式、节能模式以及高冷凝模式。
快速模式：此时，第一控制阀1300以及第二控制阀1100开启。
干衣机的快速模式的控制原理为：新风通过新风入口1200进入到干衣机的风道中；进入到干衣机的风道中的新风经加热引风组件加热形成高温低湿风，高温低湿风引入到滚筒300内；引入到滚筒300内的高温低湿风带走滚筒300内的衣物的水分，形成低温高湿风；一部分低温高湿风通过滚筒300的除湿口301排至环境中，以带走水分，另一部分低温高湿风引入到风道中，经蒸发器400冷凝出水以及冷凝器500加热后，同从新风入口补充到干衣机的风道中的新风汇集，再次被加热引风组件加热形成循环风。
快速模式下，通过与滚筒300的两端连通的风道上设置有新风入口1200，可补充引入至干衣机的滚筒300内的循环风的风量和温度，另外，可通过设置在滚筒300上设置的除湿口301将部分低温高湿风排至环境中，这样从滚筒300引入到风道的低温高湿风的含水量减少，该部分低温高湿风再经过蒸发器400冷凝出水以及冷凝器500加热后，同从新风入口1200补充到干衣机的风道中的新风汇集，再次被加热引风组件加热形成循环风，引入到滚筒300内的循环风可具有更多的风量和更高的温度，从而可提高干衣效率，降低干衣时间。
节能模式：此时，第一控制阀1300关闭，第二控制阀1100开启。
干衣机的节能模式的控制原理为：空气经加热引风组件加热形成高温低湿风，高温低湿风引入到滚筒300内；引入到滚筒300内的高温低 湿风带走滚筒300内的衣物的水分，形成低温高湿风；一部分低温高湿风通过滚筒300的除湿口301排至环境中，以带走水分，另一部分低温高湿风引入到风道中，经蒸发器400冷凝出水以及冷凝器500加热后，再次被加热引风组件加热形成循环风。
在该节能模式下，由于新风没有引入到风道中，可在一定程度上减少风机的耗能，还可以将部分低温高湿风排出至风道中，也可以在一定长度上降低干衣时间。
高冷凝模式：此时，第一控制阀1300和第二控制阀1100均关闭。
干衣机的高冷凝模式的控制原理为：空气经加热引风组件加热形成高温低湿风，高温低湿风引入到滚筒300内；引入到滚筒300内的高温低湿风带走滚筒300内的衣物的水分，形成低温高湿风；低温高湿风引入到分路中，经蒸发器400冷凝出水以及冷凝器500加热后，再次被加热引风组件加热形成循环风。
高冷凝模式所示的技术方案中，没有新风没有引入到风道中，若降低干衣时间，需要提高冷凝器的加热效果，加大循环风的温度，故称之为高冷凝模式。
在干衣机上可设置有控制面板，该控制面板上可设置有和上述干衣模式对应的指令，当用户按压或接触该控制面板对应的指令时，即可控制干衣机的不同的干衣模式；或者，也可在干衣机中设置传感器，用户可通过遥控等方式控制各种指令，以实现不同的干衣模式，对此不作具体限制。
尽管已描述了本申请的优选实施例，但本领域内的普通技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。 所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
