可选地，喷嘴303具有入口3031和出口3032，喷嘴303的入口3031与气流通道301导通，喷嘴303的出口3032的面积小于所述进风口121的面积，可以达到较好的射流、引流效果。
根据本发明又一个实施例的干衣机100包括：壳体组件10、风道组件30和风机20。
具体而言，壳体组件10包括干衣腔123和导通干衣腔123的进风口121，风道组件30设于壳体组件10，且风道组件30包括气流通道301和喷嘴303，风机20设于壳体组件10，用于驱动气流通道301内的气流从喷嘴303喷出。喷嘴303的出口3032和进风口121之间存在间隙。
根据本发明实施例的干衣机100，通过在壳体组件10上设置风道组件30，将风道组件30的喷嘴303设在进风口121处且使喷嘴303的出口3032和进风口121之间存在间隙，可以达到较好的射流、引流效果，有利于提高干衣机100的干衣效率，并且高速的气流吹动干衣机100内的衣物，可以防止褶皱产生以及去除部分褶皱，从而提高干衣 效果。
根据本发明另一个实施例的干衣机100包括：壳体组件10、风道组件30和风机20。
具体而言，壳体组件10包括干衣腔123和导通干衣腔123的进风口121，风道组件30设于壳体组件10，且风道组件30包括气流通道301和喷嘴303，风机20设于壳体组件10，用于驱动气流通道301内的气流从喷嘴303喷出；喷嘴303的出口3032的面积小于进风口121的面积。
根据本发明实施例的干衣机100，通过在壳体组件10上设置风道组件30，将风道组件30的喷嘴303设在进风口121处且使喷嘴303的出口3032面积小于进风口121的面积，可以达到较好的射流、引流效果，有利于提高干衣机100的干衣效率，并且高速的气流吹动干衣机100内的衣物，可以防止褶皱产生以及去除部分褶皱，从而提高干衣效果。
下面参考图1-图10，详细描述根据本发明实施例的干衣机100的一些实施例。
根据本发明的一个实施例，壳体组件10包括出风口122，出风口122和进风口121通过引流通道304导通，并且进风口121和出风口122均与干衣腔123导通。
工作时，喷嘴303处局部射出较高速的射流风，这样会在喷嘴303周围区域形成负压区，从而带动进风口121周围气流沿射流的方向流动，以形成引流风，从而增大了进风口121位置的风量，同时还可以导致引流通道304内的气流被引流出，引流通道304也形成负压区，因此需要外部补充气流，干衣腔123内的部分气流通过出风口122流入该引流通道304，实现气流的内外循环，从而保证气压的平衡。
在一个优选的实施方式中，出风口122位于进风口121的下方，从而更有效的引导气流循环，增加风量。
在一些示例中，风道组件30与壳体组件10之间限定出引流通道304，进风口121和出风口122分别与引流通道304连通。
如图2、图7-图9所示，在一些具体示例中，壳体组件10包括：外壳11和内胆12，内胆12设于外壳11内且具有干衣腔123，风道组件30设于外壳11与内胆12之间且与内胆12之间限定出引流通道304，干衣机100的壳体组件10结构简单、紧凑，组装容易，并且通过设置外壳11与内胆12，可以为风道组件30限定出放置空间，从而提高空间利用率。
根据本发明的一个实施例，风道组件30还包括入风口302，入风口302和风机20连通。风机20工作时，可以将外界空气引入气流通道301内以形成高速气流，然后驱动气流通道301内的气流从喷嘴303喷出，为气流流动的提供动力。
如图9所示，在一些示例中，气流通道301内设有加热模块40，可以对气流进行加 热，从而向干衣腔123内提供加热的气流，进而起到烘干衣物及去除褶皱的作用。
在一些具体示例中，加热模块40在气流流动方向上位于入风口302和邻近入风口302的喷嘴303之间。例如，加热模块40设在气流通道301内且邻近入风口302设置，从而保证每个喷嘴303均可以喷出热气流，起到烘干衣物及去除褶皱的作用。
在一些示例中，风道组件30还包括：蒸汽发生器(未示出)，由此从喷嘴303喷出的高温水蒸气，可以进一步提高去皱效果。
如图3-图9所示，根据本发明的一个实施例，风道组件30包括：主体部31，主体部31内限定有气流通道301的至少一部分，且主体部31具有入风口302和至少一个喷嘴303，主体部31与壳体组件10限定出引流通道304或者引流通道304的一部分，结构简单、组装方便。
在一些示例中，主体部31的朝向壳体组件10的一侧具有凹部312，凹部312与壳体组件10限定出引流通道304的至少一部分。具体地，主体部31具有沿其周向延伸的挡板311，且挡板311与壳体组件10密封连接，保证主体部31与壳体组件10可以限定出相对较密封的引流通道304，防气流发生泄露。
根据本发明进一步的实施例，风道组件30还包括：分支部32，分支部32内限定有气流通道301的其余部分，且分支部32具有至少一个喷嘴303，通过调整分支部32的位置可以将气流引导至干衣腔123的不同方位。
可选地，分支部32包括两个，两个分支部32的一端分别与主体部31的一端连接，且每个分支部32具有喷嘴303，通过调整分支部32的方位以及分支部32上的喷嘴303位置，可以调整进入干衣腔123内的高温气流的流量，从而提高干衣机100的干衣效率和干衣效果。
如图7-图9所示，在一些示例中，主体部31设于干衣腔123的后部，分支部32设于干衣腔123的顶部，从而在干衣腔123的后部和顶部形成高速气流以吹动衣物。
进一步地，干衣腔123内设有用于挂设衣物的挂杆14，主体部31上的喷嘴303与分支部32上的喷嘴303位于挂杆14的前后两侧。
由此，可以从主体部31的气流通道301引出一部分气流，引导至干衣腔123的顶部以及前部，这样在干衣腔123内既有从后向前的射流风，又有从前向下的射流风，使衣物前后均能吹到热风，使衣物在悬挂状态下完成烘干，并且前后两侧的热风能吹动衣物摆动，保证衣物前后均能受风，防止褶皱产生的同时，还能去除部分褶皱，增加了烘干的均匀性。
如图8所示，在一些示例中，每个喷嘴303具有入口3031和出口3032，进风口121的横截面面积大于喷嘴303的出口3032的横截面面积，且喷嘴303的出口3032在进风 口121所在平面的正投影、位于进风口121的中部，喷嘴303的出口3032在上下方向上的尺寸小于进风口121在上下方向上的尺寸。
由此，喷嘴303设在进风口121处以与进风口121形成文丘里效应，从喷嘴303喷出高速气流时，喷嘴303的周围区域形成负压区，从而带动进风口121处周围气流沿射流的方向流动，以形成引流风，这样就增大了进风口121位置的风量，从而达到更好的射流、引流效果。
根据文丘里效应原理，由于进风口121中除去喷嘴303所占区域的横截面面积B会影响引流风的风速，间接影响射流风的总风量，因此为了达到更好的射流、引流效果，进风口121中除去喷嘴303所占区域的横截面面积B(B1+B2)与喷嘴303的出口3032的横截面面积A的比值为2-50，例如二者的B/A可以为2、20、40或50等，从而达到更好的射流、引流效果。
可选地，喷嘴303的横截面面积在气流流动方向上、从入口3031到出口3032逐渐减小，且喷嘴303的入口3031的横截面面积C与喷嘴303的出口3032的横截面面积A的比值C/A小于等于20，从而能达到较好的射流效果。
优选地，喷嘴303包括多个，且多个喷嘴303中靠近入风口302的喷嘴303的入口3031处设有挡风筋3033。
在一些示例中，挡风筋3033与喷嘴303的内壁面圆弧过渡连接，挡风筋3033可以起到分流的作用，气流通道301内的气流经过挡风筋3033时，一部分改变方向，经由喷嘴303射出，另一部分则继续向前流动，通过调整挡风筋3033的高度和方向，可以调整气流被分流的比例，从而达到控制每个喷嘴303的风量较均匀的目的。
在一些示例中，风道组件30包括多个喷嘴303，多个喷嘴303沿气体流动方向依次设置，气流通道301的横截面积在沿气体流动的方向上逐渐变小。
在图7示出的示例中，气流通道301包括沿上下方向延伸的纵向通道和沿前后方向延伸的横向通道，纵向通道的横截面面积沿上下方向、从下至上逐渐减小，横向通道的横截面面积沿前后方向、从后向前逐渐减小，从而更好地分配每个喷嘴303喷出的气体流量。
下面参考图1-图10，详细描述根据本发明一个具体实施例的柜式干衣机100的工作过程。
如图1和图2所示，根据本发明实施例的柜式干衣机100包括：壳体组件10、风机20和风道组件30。壳体组件10包括外壳11、框架13、内胆12和门体15，外壳11包括位于顶板112、底板113和三个侧板111，顶板112安装于框架13的顶部，底板113安装于框架13的底部，三个侧板111分别安装于框架13的左侧、右侧和后侧，外壳11 具有前侧敞开的腔室。内胆12安装于外壳11的腔室内且具有前侧敞开的干衣腔123、四个进风口121和一个出风口122，出风口122位于四个进风口121的下方，干衣腔123内设有用于挂设衣物的挂杆14。门体15在打开位置和关闭位置之间可活动地安装于框架13以打开和关闭干衣腔123的前侧开口。
如图2-图9所示，风道组件30设于内胆12与外壳11之间且包括主体部31和两个分支部32，主体部31沿竖直方向(如图2所示的上下方向)延伸且设于内胆12的后部，主体部31朝向内胆12的一侧具有凹部312且主体部31的凹部312与内胆12之间限定出引流通道304，引流通道304分别与内胆12上的进风口121和出风口122导通，主体部31具有入风口302和两个沿其长度方向间隔设置的喷嘴303，入风口302适于与风机20连通，每个喷嘴303正对内胆12后部上的进风口121，两个分支部32的一端分别连通至主体部31的上端且至少一部分位于内胆12的顶部，每个分支部32的另一端设有喷嘴303。
如图7-图9所示，每个喷嘴303具有入口3031和出口3032，喷嘴303的横截面面积在气流方向上、从喷嘴303的入口3031到喷嘴303的出口3032逐渐减小，且喷嘴303的入口3031的横截面面积与喷嘴303的出口3032的横截面面积的比值小于等于20。进风口121的横截面面积大于喷嘴303的出口3032的横截面面积，且喷嘴303的出口3032在进风口121所在平面的正投影、位于进风口121的中部，进风口121中除去喷嘴303所占区域的横截面面积与喷嘴303的出口3032的横截面面积的比值为2-50。其中，除去最远离入风口302的喷嘴303外的其余喷嘴303处设有挡风筋3033，挡风筋3033朝向气流通道301延伸，以实现分流效果。
加热模块40设在气流通道301内且邻近入风口302设置，以气流进行加热，从而向干衣腔123内提供加热的气流，以起到烘干衣物及去除褶皱的作用。
如图10所示，通过对风道组件30进行仿真分析，发现喷嘴303处局部射出较高速的射流风，局部的风速可高达20～40m/s，这样会在喷嘴303的出口3032周围形成负压区，从而带动内胆12上的进风口121处周围气流向前沿射流的方向流动，以形成引流风，这样就增大了进风口121位置的风量。
同时，因为文丘里效应，导致气流通道301外部、挡板311内部的空间(即引流通道304)内的气流被引流出，整个引流通道304也变成负压区，因此需要外部补充气流，干衣腔123内的部分气流通过内胆12上的出风口122流入该引流通道304，实现气流的内外循环，从而保证气压的平衡。
衣物可在悬挂状态下完成烘干，且风道组件30可产生较高流速的高温射流风，能吹动衣物摆动，防止褶皱产生的同时，还能去除部分褶皱，同时衣物前后均能受风，增 加了烘干的均匀性。
下面结合图1-图10，详细描述根据本发明实施例的干衣机用风道组件30。
如图1-图10所示，根据本发明实施例的干衣机用风道组件30具有气流通道301、入风口302和至少一个喷嘴303，入风口302与喷嘴303分别与气流通道301导通，喷嘴303的至少一段横截面面积在气流的喷出方向上、逐渐减小。
根据本发明实施例的干衣机用风道组件30，将其应用至干衣机100中，可以达到较好的射流、引流效果，有利于提高干衣机100的干衣效率，并且高速的气流吹动干衣机100内的衣物，可以防止褶皱产生以及去除部分褶皱，从而提高干衣效果。
根据本发明的一个实施例，风道组件30包括：主体部31，主体部31内限定有气流通道301的至少一部分，且主体部31具有入风口302和至少一个喷嘴303。
在一些示例中，主体部31的朝向壳体组件10的一侧具有凹部312，凹部312与壳体组件10限定出引流通道304的至少一部分。具体地，主体部31具有沿其周向延伸的挡板311，且挡板311与壳体组件10密封连接，保证主体部31与壳体组件10可以限定出相对较密封的引流通道304，防气流发生泄露。
根据本发明进一步的实施例，风道组件30还包括：分支部32，分支部32与主体部31连接且内限定有气流通道301的其余部分，且分支部32具有至少一个喷嘴303，通过调整分支部32的位置可以将气流引导至干衣腔123的不同方位。
如图7-图9所示，在一些示例中，主体部31设于干衣腔123的后部，分支部32的一部分设于干衣腔123的顶部且分支部31的一端与主体部31连接，从而在干衣腔123的后部和顶部形成高速气流以吹动衣物。
进一步地，干衣腔123内设有用于挂设衣物的挂杆14，主体部31上的喷嘴303与分支部32上的喷嘴303位于挂杆14的前后两侧。
由此，可以从主体部31的气流通道301引出一部分气流，引导至干衣腔123的顶部以及前部，这样在干衣腔123内既有从后向前的射流风，又有从前向下的射流风，使衣物前后均能吹到热风，使衣物在悬挂状态下完成烘干，并且前后两侧的热风能吹动衣物摆动，保证衣物前后均能受风，防止褶皱产生的同时，还能去除部分褶皱，增加了烘干的均匀性。
在一些示例中，喷嘴303的横截面面积在气流流动方向上、从喷嘴303的入口3031到喷嘴303的出口3032逐渐减小，且喷嘴303的入口3031的横截面面积C与喷嘴303的出口3032的横截面面积A的比值C/A小于等于20，从而能达到较好的射流效果。
在一些示例中，喷嘴303包括多个，且多个喷嘴303中在气流方向上、靠近入风口302的喷嘴303的入口3031处设有挡风筋3033。
在一些具体示例中，挡风筋3033与喷嘴303的内壁面圆弧过渡连接，挡风筋3033可以起到分流的作用，气流通道301内的风经过挡风筋3033时，一部分改变方向，经由喷嘴303射出，另一部分则继续向前流动，通过调整挡风筋3033的高度，可以调整气流被分流的比例，从而达到控制每个喷嘴303的风量较均匀的目的。
在一些示例中，喷嘴303包括多个，且多个喷嘴303沿气体流动方向依次设置，气流通道301的横截面积在沿气体流动的方向上逐渐变小，从而更好地分配每个喷嘴喷出的气体流量。
根据本发明进一步的实施例，干衣机100具有干衣腔123和导通干衣腔123的进风口121，喷嘴303设在进风口121处，且喷嘴303的出口3032和进风口121之间存在间隙。
根据文丘里效应原理，由于进风口121中除去喷嘴303所占区域的横截面面积会影响引流风的风速，间接影响射流风的总风量，因此，为了达到更好的射流、引流效果，进风口121中除去喷嘴303所占区域的横截面面积B与喷嘴303的出口3032的横截面面积A的比值B/A为2-50，从而达到更好的射流、引流效果。
在一些示例中，喷嘴303的出口3032在进风口121所在平面的正投影、位于进风口121的中部。也就是说，喷嘴303设在进风口121处以与进风口121形成文丘里效应，从喷嘴303喷出高速气流时，喷嘴303的周围区域形成负压区，从而带动进风口121处周围气流沿射流的方向流动，以形成引流风，这样就增大了进风口121位置的风量，从而达到更好的射流、引流效果。
在一些示例中，干衣机100具有与干衣腔123导通的出风口122，风道组件30适于安装于干衣机100的壳体组件10且与壳体组件10限定出与进风口121、出风口122导通的引流通道304。
工作时，喷嘴303处局部射出较高速的射流风，局部的风速可高达20～40m/s，这样会在喷嘴303的出口3032周围形成负压区，从而带动内胆12上的进风口121处周围气流向前沿射流的方向流动，以形成引流风，这样就增大了进风口121位置的风量。同时，因为文丘里效应，导致引流通道304内的气流被引流出，整个引流通道304也变成负压区，因此需要外部补充气流，干衣腔123内的部分气流通过内胆12上的出风口122流入该引流通道304，实现气流的内外循环，从而保证气压的平衡。
