以下基于实施例对本申请进行描述，本领域普通技术人员应当理解，在此提供的附图仅用于结构性示意，与实际比例无关。
除非上下文明确要求，否则整个说明书和权利要求书中的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义；也就是说，是“包括但不限于”的含义。本说明书中涉及到的“多个”是指两个及两个以上。
说明：本申请说明书中涉及到上、下、左、右等方位，以图3中所示的方位为准。
本申请提供了一种进风风道结构，用于向设备的腔室中引入外部干燥气流，所述腔室内使用液体进行工作，比如所述进风风道结构可以设置在洗碗机、洗干一体机等既需要进行洗涤又需要进行干燥的设备中。
下面以应用在洗碗机上的进风风道结构为例，对进风风道结构的具体结构进行详细说明。如图1至图5所示，本申请中的进风风道结构设置在洗碗机的内胆2的外壁面21与洗碗机的壳体(图中未示出)之间，所述进风风道结构具有出风口611，所述内胆2上开设有安装孔(图中未示出)，所述安装孔与所述出风口611对应设置，以使进风风道结构的内部风道与洗碗机的内胆2的内腔连通。在所述风道结构的内部，靠近所述风道结构的出风口611所在位置处设置有挡水结构3，所述挡水结构3靠近所述出风口611的位置沿着气流的流动方向朝向所述出风口611延伸，以将从所述内胆2中飞溅到所述挡水结构3上的水，引流至所述出风口611处，进而流回至内胆中，不易在所述风道结构的风道中产生积水，避免水沿着所述风道结构的内壁向下流动至所述风道结构中设置的电子元器件上，保证使用安全。
进一步地，如图2和图3所示，所述风道结构包括呈倒U形或倒V形的第一风道段61，所述出风口611设置在所述第一风道段61的端部。所述第一风道段61的形状能够进一步防止飞溅到所述风道结构中的水沿着所述风道结构的内壁向下流动，保护风道结构中 设置的电子元件不会因进水发生损坏。所述挡水结构3在与所述内胆2的侧壁平行的风道结构的侧壁上的延伸方向与所述第一风道段61的形状大致相同。所述第一风道段61与所述挡水结构3共同作用，大大减小了进入风道结构中的水量，保持所述风道结构的内部干燥，减少细菌滋生，保证洗碗机中餐具的洁净度。
进一步地，如图2所示，所述挡水结构3包括挡水筋板31，所述挡水筋板31设置在所述第一风道段61的侧壁612上。所述挡水筋板31相对于所述侧壁612垂直延伸，或者，所述挡水筋板31相对所述侧壁612以预定角度延伸。从而保证所述挡水筋板31能够对飞溅到所述风道结构的风道中的水进行有效的阻挡。在一个具体的实施例中，所述挡水筋板31从一个侧壁延伸至与其相对的另个侧壁上，如此，所述挡水筋板31将所述第一风道段61中的风道划分为两个风道。所述风道结构的风道中的气流流动到所述挡水筋板31所在位置处，气流的流速加快，能够对飞溅到风道中的水起到一定的阻挡作用。由于气流流速加快，能够在一定程度上提高干燥效率，加快内胆中餐具的干燥速度。在另一个具体的实施例中，所述风道主体6采用吹塑方式加工成型，所述挡水筋板31随所述风道主体6一起吹塑成型，所述挡水筋板31包括两条子筋板(图中未示出)，两条子筋板分别从一个侧壁延伸至与该侧壁相对的另一侧壁，两条子筋板之间具有一定的夹角，以在多个方向上对飞溅到风道中的水进行阻挡，且更容易吹塑成型。
再进一步地，所述风道结构的侧壁上靠近所述风道结构的出风口611所在位置处设置有导流结构，所述导流结构用于将所述风道结构的侧壁上的液体向所述出风口611方向导流。在一个具体的实施例中，如图1所示，所述第一风道段61包括侧壁612，所述侧壁612包括第一侧壁6121，与所述第一侧壁6121相连接的第二侧壁6122和第三侧壁6123，其中，所述第二侧壁6122和第三侧壁6123是所述第一风道段61在其厚度方向的侧壁。所述第三侧壁6123与所述第二侧壁6122相连，并位于所述第二侧壁6122的下方，所述第三侧壁6123还与所述第一连接结构41相连接。所述第一侧壁6121与所述第二侧壁6122相互垂直，所述第一侧壁6121与所述第三侧壁6123之间具有呈锐角的夹角，所述第三侧壁6123构成所述导流结构，对所述风道结构的侧壁上的液体进行导流，使其从侧壁朝向所述出风口611流动，进而避免其积存在所述风道中。
更进一步地，如图1所示，所述风道结构包括相互连接的入风部1、出风部4和风道主体6，气流从所述入风部1输入所述风道主体6，然后从所述风道主体6经所述出风部4输入所述腔室内；其中，所述入风部1和出风部4采用注塑方式加工成形，所述风道主体6采用吹塑方式加工成形。其中，所述第一风道段61形成所述风道主体6的一部分，所述挡水结构3设置在所述风道主体6中，与所述风道主体6一体成形。当然，可以理解的是， 所述挡水结构3和所述风道主体6也可以分别进行加工，然后再通过机械方式固定连接在一起。所述出风部4上设置有第一连接结构41，如图5所示，所述腔室中设置有用于防止液体进入到所述风道结构中的风道内的盖体8，所述盖体8上设置有第二连接结构81，所述第二连接结构81由内向外穿过所述腔室的侧壁，与所述第一连接结构41相连接。
在对所述风道主体6进行吹塑加工过程中，采用注塑方式加工成形的出风部4作为镶件放置到模具中，再对所述风道主体6进行吹塑，以将所述出风部4与所述风道主体6连接在一起。由于所述第一连接结构41比较复杂，所述风道主体6的结构比较简单，将结构复杂的第一连接结构41注塑出来，对结构比较简单的风道主体6采用吹塑的方式进行加工，能够有效提高加工生产效率。现有的风道结构有的是将第一连接结构41和风道主体6分别注塑成型，再通过机械加工方式将两者连接在一起。这样的加工方式容易在连接处形成缝隙，缝隙中容积积聚细菌和昆虫，无法保证风道结构内部的清洁性。本申请中的第一连接结构41作为镶件与所述风道主体6采用吹塑方式成形，两者连接位置处没有缝隙，便于维护，由于没有缝隙死角，因此不容易积灰，不易有小虫子隐藏在其中。其中，所述第一连接结构41和所述第二连接结构81之间为螺纹连接或者卡接，既方便拆装，又能够保证连接可靠性。
更进一步地，所述风道主体6呈竖向设置，所述入风部1包括横向部分11和弯曲或弯折部分12，所述横向部分11通过所述弯曲或弯折部分12与所述风道主体6远离所述出风口611的一端相连接，所述入风部1和风道主体6之间为可拆卸连接。其中，在所述入风部1中设置有气流产生结构和/或加热组件(图中未示出)，优选地，所述气流产生结构和/或所述加热组件设置在所述横向部分11中。在一个优选的实施例中，所述入风部1与所述风道主体6之间通过卡接的方式连接在一起。在另一个较优的实施例中，所述入风部1与所述风道主体6之间通过比如螺栓等紧固件固定连接在一起。进一步地，在所述弯曲或弯折部分12的与所述横向部分11相连接的一端上设置有溢流槽121，所述溢流槽121能够在所述弯曲或弯折部分12的侧壁上有少量液体时，将液体积存在所述溢流槽121中，避免液体沿着所述弯曲或弯折部分12的侧壁流到所述横向部分11中，造成所述横向部分11中的用电器件发生损坏。
如图4和图1所示，为了保证所述内胆2中餐具的洁净性，所述风道结构还包括过滤部件7，所述过滤部件7优选为过滤网71。所述过滤部件7设置在所述出风口611处和/或所述气流产生结构的进风口处，以避免洗碗机外部环境中粉尘、碎屑等杂物随气流进入到所述洗碗机中，保证洗碗机中的餐具不会受到污染。
本申请还提出了一种洗涤设备，包括壳体和设置在所述壳体中的内胆，所述内胆的腔室内使用液体进行工作，所述内胆的侧壁上设置有上述进风风道结构，所述进风风道结构位于所述内胆与所述壳体之间。所述洗涤设备包括洗碗机，洗干一体机等。
由于所述洗涤设备上设置有上述进风风道结构，因此，所述洗涤设备的进风风道结构中不易积水，能够保护所述风道结构中设置的比如加热装置、气流产生结构等电子器件不会因进水而损坏，保证洗涤设备的使用可靠性和安全性。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各优选方案可以自由地组合、叠加。
以上所述仅为本申请的优选实施例，并不用于限制本申请，对于本领域技术人员而言，本申请可以有各种改动和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
