技术领域
本公开涉及制冷设备技术领域，尤其涉及排水板、风道组件、箱胆及制冷设备。
背景技术
随着生活品质的提升，消费者对于冰箱内存储空间需求越来越高，冰箱内存储空间的大小也成为消费者的关注点。如何在冰箱体积不变的情况下增大冰箱的存储空间，成为技术人员的一个研发方向。其中，制冷系统的部件需要占用柜体的一部分体积，制冷系统的部件在柜体内的安装位置，会影响柜体的体积以及柜体限制出存储空间的大小。当制冷系统中的蒸发器设置在冰箱的制冷间室的后侧，柜体的厚度较大，柜体深度方向的存储空间不足。当制冷系统中的蒸发器横置在两个间室之间，蒸发器不占用制冷间室后侧的空间，此时，为了保证化霜水的排出，需要将蒸发器向下倾斜较大角度，以使化霜水靠重力排出，受蒸发器影响，蒸发器等部件高度方向落差越大，导致占用的高度空间越大，间室内损失的容积越大，仍会影响冰箱的存储空间，有待优化。

本公开的实施例，结合图1至图13所示，提供一种制冷设备，包括柜体400，柜体400包括箱胆。
制冷设备可以为冰箱、冰柜、展示柜、售卖柜或酒柜等多种设备，制冷设备可用于冷藏或冷冻。
其中，下述实施例中，前后左右上下的方位，与制冷设备的方位一一对应。
本公开的实施例，如图1所示，提供一种箱胆，箱胆包括箱胆本体和风道组件200，箱胆本体内的空间通过风道组件200分隔出相互独立的第一间室410和第二间室420。
风道组件200可起到分隔间室的作用，还可以起到循环送风的作用。需要说明的是，为了保证第一间室410与第二间室420的独立性，风道组件200与箱胆本体的安装处需要保证密封，避免第一间室410与第二间室420之间串风。
本公开的实施例，提供一种风道组件200，风道组件200可将箱胆本体内的全部空间分成第一间室410和第二间室420两部分，或者，风道组件200将箱胆本体内的局部空间分隔成第一间室410和第二间室420两部分。
风道组件200向第一间室410和第二间室420独立送风，第一间室410与第二间室420的功能可相同或不同。当第一间室410与第二间室420的功能不同，也就是第一间室410与第二间室420内的环境温度不同，第一间室410可为冷藏室，第二间室420可为冷冻室，则风道组件200向冷藏室送风的频率低于向冷冻室送风的温 度。当第一间室410与第二间室420的功能相同，如均为冷藏室，两个冷藏室的环境温度可相同或不同，此时，风道组件200向两个冷藏室送风的频率可相同或不同，具体可根据需要设置。当然，风道组件200分隔出的间室，功能不限于冷藏和冷冻，还可以为变温间室或其他功能间室，具体可根据需要设置。
当柜体400连接门体，门体在封闭柜体400的位置，则第一间室410与第二间室420为两个密闭且独立的空间；门体在打开柜体400的位置，则可从第一间室410与第二间室420中的至少一个取放物品。
其中，风道组件200在制冷设备内设置的数量可根据需要设置。
可以理解的是，如图2至图8所示，风道组件200包括隔板部件210、风道部件220、蒸发器230和排水板100，隔板部件210位于风道部件220的上方，隔板部件210与风道部件220构造出第一腔体260、适于与第一腔体260连通的进风口和适于与第一腔体260连通的出风口，第一腔体260内设置蒸发器230与排水板100，排水板100位于蒸发器230的下方。
隔板部件210连接于箱胆本体，并使隔板部件210与箱胆本体的连接处相密封，以将箱胆本体内的空间分隔出相互独立的第一间室410和第二间室420。隔板部件210与风道部件220之间的第一腔体260用于安装蒸发器230、排水板100、加热器240等部件，以满足第一间室410与第二间室420的换热需求。
隔板部件210可固定连接于箱胆本体，如隔板部件210的边缘通过焊接、卡接或紧固件等方式固定于箱胆本体。隔板部件210包括第一板体211和第二板体212，第一板体211与第二板体212之间设置第一保温层213，第一保温层213可为可拆卸设置于第一板体211与第二板体212之间，或第一保温层213与第一板体211和第二板体212一体发泡成型。
当第一保温层213与第一板体211和第二板体212一体发泡成型，可先将第一板体211与第二板体212与箱胆本体固定安装，第一保温层213与柜体400的保温层一体发泡成型，隔板部件210与箱胆本体之间的密封性能更好，避免第一间室410与第二间室420之间串风。
隔板部件210还包括第三板体214，第三板体214与第一板体211和第二板体212限制出安装空间，第三板体214位于风道组件200的前方，安装空间位于隔板部件210的前方，安装空间用于安装功能部件，如控制器、照明模块、交互模块以及显示模块等。
风道部件220也连接于箱胆本体，风道部件220支撑排水板100，排水板100位于蒸发器230的下方，排水板100的出口侧设置导水件223，导水件223与排水管290连通，排水板100的出口114排出的水沿导水件223引流到排水管290。
可以理解的是，蒸发器230与水平方向形成的夹角小于或等于预设角度，以减小蒸发器230所占用的高度方向空间，可减小风道组件200的整体高度，达到扩大制冷设备容量的目的。此处，蒸发器230与水平方向形成夹角，可以理解为蒸发器230的底面与水平方向形成夹角，或，蒸发器230的对称面与水平方向形成夹角，蒸发器230的顶面与底面相对于对称面对称。一般情况下，蒸发器230的顶面 与底面相互平行。
其中，结合图9至图13所示的排水板100结构，预设角度可为7°，能够满足蒸发器230的化霜排水要求，同时减小风道组件200的整体高度。此时，排水板100的顶面一般平行于蒸发器230的底面。
可以理解的是，预设角度可为0°，此时，蒸发器230的底面平行于水平面，可理解为蒸发器230水平设置，相对于蒸发器230倾斜设置的情况，水平设置的蒸发器230所需安装空间的高度变小，则风道组件200高度方向尺寸可随之变小，进而风道组件200所占用的箱胆本体内的空间变小，在箱胆本体的外观尺寸不变的情况下，可有效提高箱胆本体的容量，以便提供一种大容量的制冷设备。
此时，并不限定排水板100的安装状态，排水板100的顶面与蒸发器230的底面平行，或，排水板100的顶面相对于蒸发器230的底面从前向后斜向下倾斜。
可以理解的是，排水板100的顶面也平行于水平面，也就是，蒸发器230的底面与排水板100的顶面均水平放置，蒸发器230的底面与排水板100的顶面相平行或相接触，蒸发器230与排水板100之间的间隙变小，可阻止第一腔体260内的风从蒸发器230与排水板100之间的间隙直接流向出风口，有助于风在第一腔体260内充分换热。
需要说明的是，尽量减小蒸发器230与排水板100之间的间隙，减缓风从蒸发器230与排水板100之间的间隙流向出风口的速度，延长风在第一腔体260内停留的时间，以使风在第一腔体260内充分与蒸发器230进行换热再流出，保证换热效率。
可以理解的是，风道组件200的出风口与排水板100的出口114错位设置，阻止随水一同流动到出口114位置的风直接从出风口排出，延长风在第一腔体260内换热的时间，提升换热效果。
当排水板100包括导水部120和排水部110，排水部110构造有出口114，排水板100承接的水沿导水部120向排水部110流动并从出口114排出，与此同时，一部分风也沿着导水部120和排水部110向出口114流动，将出口114与出风口设置为错位，则可阻止流向出口114的风直接从出风口排出，尽量延长风在第一腔体260内换热的时间，提升换热效果。
可以理解的是，风道组件200包括风道盖板251以及连接于风道盖板251的风机252，风机252与排水部110的出口114错位设置，风道盖板251对应于风机252的位置开设出风口，以使第一腔体260内的风通过出风口，在风机252的作用下排出第一腔体260。排水板100的出口114与出风口错位设置，可减少出口114处被风机252抽出的风，延长风在第一腔体260内的换热时间。
风道盖板251固定在箱胆本体上，并与箱胆本体之间围设出第二腔体270，第二腔体270通过出风口与第一腔体260连通。或者，风道盖板251自身围设出的第二腔体270，第二腔体270与第一腔体260连通，风道盖板251固定安装在箱胆本体上。风道盖板251与导水件223之间限制出第三腔体280，第一腔体260内的风通过第三腔体280再被风机252导出。
风道组件200的进风口、第一腔体260、出风口连通，以便进入风道部件220的风换热后排出。风道组件200的进风口分为第一进风口2121和第二进风口2221，风道组件200还设置第一排风口和第二排风口256，第一进风口2121、第一腔体260、出风口、第一排风口与第一间室410连通形成第一循环路径，第二进风口2221、第一腔体260、出风口、第二排风口256与第二间室420连通形成第二循环路径，第一循环路径与第二循环路径中的至少一个连通，以便第一间室410与第二间室420送风。第一进风口2121、第二进风口2221、第一排风口以及第二排风口256的数量和位置不作限定。
如图1所示，第一间室410位于风道组件200的上方，第一间室410被设置为冷藏室，第二间室420位于风道组件200的下方，第二间室420被设置为冷冻室，风道组件200设置有朝向上方的第一排风口和朝向下方的第二排风口；并在第一排风口处设置第一风门255，以便开闭调节，隔板部件210对应位置开设适于安装第一风门255的孔；在第二排风口256处设置第二风门，以便开闭调节。风道组件200靠向前端的位置设置有第一进风口和第二进风口，第一进风口与冷藏室的回风风道连通，第一进风口设置风道组件的左右两侧，第二进风口与冷冻室连通，第二进风口设置在风道组件的前侧或下侧。
风道盖板251设置有第一导风部253和第二导风部254，第一导风部253与第二导风部254配合向第一排风口和第二排风口256导风。
风道部件220包括支撑板以及设于排水板100下方的第二保温层221，支撑板支撑在第二保温层221下方，第二保温层221上表面的形状与排水板100下表面的形状相适配，使得第二保温层221充分为排水板100进行保温，减少冷量向外扩散，保证换热效率。
当排水板100的下表面为曲面，如波浪形，则第二保温层221的上表面为对应的曲面；当排水板100的下表面为平面，则第二保温层221的上表面为平面，具体可根据需要设置。
其中，支撑板包括第一支撑部222和沿第一支撑部222斜向下倾斜的第二支撑部225，第二支撑部225与排水板100的出口114位于风道组件200的同侧，第一支撑部222支撑第二保温层221，第二支撑部225上方设置第三保温层224，第三保温层224上方设置导水件223，第二支撑部225起到支撑第三保温层224和导水件223的作用。
第一支撑部222与第二支撑部225为相互独立的零件，如板件，通过可拆卸连接的方式安装，如插接、卡接及紧固件等方式；或，第一支撑部222与第二支撑部225为一体成型的结构，可减少零件数量，简化装配。在一些情况下，导水件223与排水板100为两个独立的零件，当然，导水件223与排水板100也可成型为一体式结构。
一些情况下，排水板100的上方设置加热器240，也就是，加热器240设置在排水板100与蒸发器230之间，在蒸发器230需要化霜时，开启加热器240，加热器240产生的热量用于加热蒸发器230表面附着的霜。
当然，加热器240不限定于设置在排水板100与蒸发器230之间，此时，加热器240可设置为加热膜，加热膜贴附在排水板100的下表面；或者，加热器240可设置在蒸发器230的换热管之间，如加热器240包括多根直插式加热棒，加热棒插接在两层换热管之间，此时加热棒与换热管以及换热管上的翅片的换热效率更高，还能提高加热化霜的效率。当加热器240不设置在排水板100与蒸发器230之间，蒸发器230可直接设置在排水板100上，可有效减小蒸发器230与排水板100之间的间隙，起到减缓风速的作用，也能起到提高换热效率的作用。
上述实时例中，蒸发器230为制冷设备中制冷系统的一部分，制冷系统包括压缩机、冷凝器、节流元件和蒸发器230，制冷系统中的制冷剂在蒸发器230中蒸发吸热，为第一腔体260内的风提供制冷环境。
下面，结合图7至图13所示，提供排水板100的实施例，以排水板100安装于上述的风道组件200内为例，对排水板100的结构进行说明。但排水板100不限于安装在上述的风道组件200内，其他适于安装下述实施例中的排水板100的结构，亦可安装下述的排水板100。
本公开的实施例，结合图9至图13所示，提供一种排水板100，排水板100构造有排水部110和导水部120，排水部110构造有出口114，排水部110相对于排水板100的顶面凹陷；导水部120与排水部110连通，导水部120相对于排水板100的顶面凹陷，导水部120的延伸方向与排水板100上方的出风方向形成第一夹角θ 1。
在使用状态，排水板100设置在蒸发器230的下方，用于承接蒸发器230表面的霜遇热而产生的化霜水。水落入导水部120并沿导水部120的延伸方向导入排水部110，导水部120一般设置多个，各个导水部120承接到的水汇集到排水部110并通过排水部110的出口114排出。
当上述的排水板100与蒸发器230均设置在风道组件200内，风从风道组件200的进风口进入第一腔体260并向出风口的方向流动，第一腔体260内的风会在排水板100与蒸发器230之间的空间以及蒸发器230内部的空间流动。风在排水板100与蒸发器230之间流动时，导水部120与出风方向形成第一夹角θ 1，可抑制风从导水部120直接流向出风口，以延长风在第一腔体260内停留的时间，以使风充分与蒸发器230接触并进行换热，换热后的风再从出风口排出，有助于提升换热效率。
其中，出风方向为进风口向出风口的方向，一些情况下，进风口与出风口仅设置一个，为一一对应的关系，形成一个出风方向；一些情况下，进风口或出风口中的至少一个设置多个，可形成多个出风方向。导水部120的延伸方向与至少一个出风方向形成夹角，可在一个方向上，保证风的换热效率；当然，导水部120的延伸方向与所有的出风方向均形成夹角，则可保证多个流动路径中的风均能有效换热，可保证换热效率。
当进风口分为第一进风口2121和第二进风口2221，第一进风口2121设置在风道组件200的前方，出风口设置在风道组件200的后方，第一进风口2121与出风口的连通路径形成第一出风方向，第一进风口2121对应于蒸发器230靠下的位置， 则风沿从下向上、从前向后的方向流动。本实施例的排水板100，导水部120的延伸方向与第一出风方向形成夹角，也就是导水部120的延伸方向与前后方向形成夹角。第二进风口2221可设置在风道组件200的左右两侧中的至少一个，第二进风口2221与出风口的连通路径形成第二出风方向，导水部120的延伸方向与第二出风方向也形成夹角。导水部120的延伸方向与第一出风方向形成的夹角，导水部120的延伸方向与第二出风方向也形成夹角，均可理解为第一夹角θ 1。
导水部120的延伸方向可以为直线路径或曲线路径。当导水部120的延伸路径为直线路径，导水部120远离排水部110的一端到导水部120连通排水部110的另一端的路径为延伸路径；当导水部120的延伸路径为曲线路径，曲线路径的导水部120可具有多个与排水部110连通的端头，曲线路径可为多段直线路径连通形成的折线路径，或，曲线路径为具有一个或多个曲率半径的曲线，曲线路径的形状可根据需要设置。一个导水部120的延伸方向可与出风方向形成一个或多个夹角，也就是第一夹角θ 1可以为一个或多个角度值，具体可根据需要设置。
图10中排水板上方的实线箭头示意了导水部的延伸方向，虚线箭头示意了出风方向，并标示第一夹角θ 1，图中示意了第一夹角为90°的情况。
需要说明的是，导水部120和排水部110均基于排水板100的顶面凹陷，顶面可以为平面或曲面，顶面可为多条线限制出的面，或多个面限制出的面。与之对应的，导水部120的底部以及排水部110的底部形成排水板100的底面，底面也可以为平面或曲面，底面可为多条线限制出的面，或多个面限制出的面。排水板100的上表面为排水板100朝向上方的全部表面，顶面为上表面的一部分；排水板100的下表面为排水板100朝向下方的全部表面，底面为下表面的一部分。
本实施例的排水板100，导水部120与排水部110配合，可将承接的水排出，解决风道组件200内排水的问题，并且，通过将导水部120设置为延伸方向与风道组件200的出风方向形成夹角，可延长风在风道组件200内停留的时间，也就是延长换热时间，以提升换热效率，满足制冷设备的制冷需求；并排水板100的结构简单。
朝向排水部110的方向，导水部120凹陷的深度逐渐增大，其中，导水部120朝向排水部110的方向深度逐渐增大，以使水在重力作用下流向排水部110并从排水部110的出口114排出。
可以理解的是，朝向排水部110的方向，导水部120的底部沿第一方向倾斜，第一方向与排水板100的顶面形成第二夹角θ 2。也就是导水部120的底部倾斜，导水部120内的水沿倾斜路径(第一方向)汇集到排水部110，排水效果好，可避免出现局部积水的问题；并且水能平稳流动。
当排水板100的顶面水平设置，可以理解为，第一方向与水平面形成第二夹角θ 2。沿排水板100的顶面，从远离排水部110的一端向与排水部110连通的位置逐渐向下凹陷形成导水部120。此时，第二夹角θ 2为导水部120的底部与水平面的夹角，第一方向为斜向下的方向。
其中，导水部120的底部，可以为斜线或斜面，一些情况下，导水部120的底 部为斜面，斜面可以为平面或曲面，具体可根据需要选择。
一些情况下，导水部120的底部不形成连续的斜线或斜面，如阶梯状，依然能够满足导水需求。
可以理解的是，第二夹角θ 2小于或等于7°，第二夹角θ 2的角度小，有助于减小排水板100顶面到底面的距离，可实现小角度排水，进而减小风道组件200在高度方向的尺寸，缩小风道组件200所占用的空间，有助于提升制冷设备的储物空间，提供一种大容量的制冷设备。
一些情况下，第二夹角θ 2设置为3°，3°能够满足排水板100的排水需求，还能充分减小排水板100的高度，实现小角度排水。
可以理解的是，多个并列设置在排水部110同侧的导水部120，所对应的排水板100的底面共面，使得排水板100的底面平整性更好，排水板100的外观简洁，且方便定位和安装。
此处的并列设置，可以理解为，在排水部110的延伸方向的一侧，多个导水部120依次排列。一般情况下，排水部110的两侧均并列设置有多个导水部120，也就是，排水部110设置在两列导水部120之间。当然，当排水部110设置在排水板100的端部，则导水部120仅设置在排水部110的一侧。
可以理解的是，导水部120的延伸方向与出风方向相垂直，可有效阻止风从导水部120限制出的空间排出，有效延长风在第一腔体260内停留的时间，以充分换热。
可以理解的是，朝向出口114的方向，排水部110凹陷的深度逐渐增大，以便排水部110内的水在重力作用下流向出口114。
可以理解的是，排水部110的底部沿第二方向倾斜，第二方向与排水板100的顶面形成第三夹角θ 3。也就是排水部110的底部倾斜，排水部110内的水沿倾斜路径(第二方向)汇集到出口114并排出，排水效果好，可避免出现局部积水的问题；并且水能平稳流动。
当排水板100的顶面水平设置，可以理解为，第二方向与水平面形成第三夹角θ 3。沿排水板100的顶面，朝向出口114的位置逐渐向下凹陷形成排水部110。此时，第三夹角θ 3为排水部110的底部与水平面的夹角，第二方向为斜向下的方向。
其中，排水部110的底部，可以为斜线或斜面，一些情况下，排水部110的底部为斜面，斜面可以为平面或曲面，具体可根据需要选择。
一些情况下，排水部110的底部不形成连续的斜线或斜面，如阶梯状，依然能够满足排水需求。
可以理解的是，第三夹角θ 3可小于或等于7°，第三夹角θ 3的角度小，有助于减小排水板100顶面到底面的距离，可实现小角度排水，进而减小风道组件200在高度方向的尺寸，缩小风道组件200所占用的空间，有助于提升制冷设备的储物空间，提供一种大容量的制冷设备。
需要说明的是，第三夹角θ 3也可大于7°，由于排水部110所占用排水板100 的面积较少，排水部110向下倾斜的角度稍大，对排水板100的整体体积影响不大，因此，对第三夹角θ 3的角度不做严格限定。
可以理解的是，排水部110的延伸方向与出风方向形成第四夹角，尽量减少风沿排水部110的延伸方向排出，也可延长风在第一腔体260内停留的时间，保证换热效果。
当然，排水部110也可沿出风方向延伸，排水部110的两侧可对称设置导水部120，方便排水部110两侧的导水部120均匀稳定导水。
如图9和图13所示，当排水部110沿出风方向延伸，导水部120与出风方向相垂直，尽量减少进入导水部120的风。
可以理解的是，如图11和图12所示，排水部110凹陷的深度大于或等于导水部120凹陷的深度。也就是，排水部110的最小深度需要大于或等于导水部120的最大深度，以使导水部120的水可汇聚到排水部110，避免导水部120积水。
可以理解的是，如图9、图10以及图13所示，排水部110的两侧均设置多个相平行的导水部120，多个导水部120将不同部位的水导入排水部110。通过设置多个导水部120，也可以理解为，排水部110的两侧均形成波浪形结构，尽量减少排水板100顶面的面积，减少排水板100顶面的积水，使得排水板100所承接的水尽快沿导水部120和排水部110从出口114排出。
可以理解的是，如图9和图10所示，排水部110至少设置两个，两个及以上的排水部110则具有两个及以上的出口114，实现多个位置排水，有助于排水板100上的水快速排出。在排水板面积不变的情况下，排水部110的数量增多，则可缩短导水部120的长度，水尽快进入排水部110。
相邻排水部110为第一排水部111和第二排水部112，第一排水部111和第二排水部112之间构造有位于第一排水部111的一侧的第一导水区130和位于第二排水部112的一侧的第二导水区140，朝向第一排水部111的方向，第一导水区130的导水部120凹陷的深度逐渐增大，朝向第二排水部112的方向，第二导水区140的导水部120凹陷的深度逐渐增大。也就是，第一导水区130与第二导水区140对接位置，导水部120凹陷的深度最小，有助于第一导水区130承接的水导入到第一排水部111，第二导水区140承接的水导入到第二排水部112，缩短导水部120的长度，便于水汇集到排水部110。
当然，如图13所示，排水部110还可设置一个，此时，排水部110的出口114尽量避开出风口。排水部110的两侧均设置多个相平行的导水部120，有助于缩短导水部120的导水路径，以加快水导出。
如图4以及图10至图12所示，排水部110从前向后延伸，开口设置在排水板100后端，导水部120沿左右方向延伸，排水部110的左右两侧形成波浪形结构，波浪板的设置可以利于水聚拢排出，此时蒸发器230无需沿着前后方向倾斜设置。导水部120与排水板100的顶面形成小于7°的夹角，也就是，排水板100的左右方向形成有倾斜延伸的导水部120，导水部120的倾斜角度不影响排水板100前后方向的角度。排水部110从前向后延伸，排水部110从前向后与水平面形成第三夹角θ 3，第三夹角θ 3会影响排水板100前后方向的高度变化，但整体上来看，排水部110设置在排水板100的局部位置，排水部110所占用排水板100的面积较小，排水板100的局部位置倾角稍大，对间室内整体储物空间的影响较小，也能优化间室内的容积。
可以理解的是，参考图12所示，导水部120包括沿导水部120的延伸方向设置的第一导流面121，从排水板100的顶面向底面的方向，第一导流面121向其相对的侧面靠近，也就是，导水部120的纵截面从上向下收拢，以使落在第一导流面121以及顶面的水可汇集到导水部120的底部，再沿导水部120汇集到排水部110。
导水部120沿其延伸方向的两侧侧面中，至少一个侧面设置为第一导流面121。导水部120纵截面的形状可为倒三角形或倒梯形。参考图12所示，导水部120延伸方向的两侧侧面均为第一导流面121，导水部120的两侧均可进行导流。
可以理解的是，参考图11所示，排水部110包括沿排水部110延伸方向设置的第二导流面113，从排水板100的顶面向底面的方向，第二导流面113向其相对的侧面靠近，以使排水部110的纵截面从上向下收拢，落在第二导流面113及顶面的水可汇集到排水部110的底部，再从出口114排出。
排水部110沿其延伸方向的两侧侧面中，至少一个侧面设置为第二导流面113。排水部110纵截面的形状可为倒三角形或倒梯形。参考图11所示，排水部110延伸方向的两侧侧面均为第二导流面113，排水部110的两侧均可进行导流。
如图11和图12所示，导水部120设置第一导流面121，排水部110设置第二导流面113，充分导流，以便排水板100所承接的水尽快从出口114排出。
上述实施例中，第一导流面121与第二导流面113可为平面或曲面，具体可根据需要选择。
可以理解的是，导水部120延伸方向的第一预设截面，朝向排水部110的方向导水部120的宽度逐渐减小。还可以理解为，朝向排水部110的方向，导水部120呈逐渐收拢的状态，以使导水部120内的水汇聚，有助于导水部120内的水进入排水部110。
此处的第一预设截面，可以理解为，平行于排水板100顶面的截面，排水板100处于安装状态的水平截面。导水部的宽度可以理解为导水部120延伸方向的两个侧壁之间的距离，也就是两个第一导流面121之间的距离。逐渐减小一般为连续减小，但不排除阶梯减小。
可以理解的是，排水部110延伸方向的第二预设截面，朝向出口114的方向排水部110的宽度逐渐增大。多个导水部承接的化霜水向排水部110汇聚，排水部110的出口114的位置水量最大，排水部110的宽度增大，可提供更大的排水空间，有助于水稳定排出。
此处的第二预设截面，可以理解为，平行于排水板100顶面的截面，排水板100处于安装状态的水平截面。排水部的宽度可以理解为排水部110延伸方向的两个侧壁之间的距离，也就是两个第二导流面113之间的距离。增大一般为连续增大，但不排除阶梯增大。
第一预设截面与第二预设截面平行，也可共面。
可以理解的是，如图9所示，排水板100的边缘向上翻折构造出翻边150，翻边150环绕排水板100且在对应于出口114的位置设置有开口。翻边150起到阻隔排水板100上表面的水向外溢流的作用，以使排水板100上表面的水均沿出口114排出，进而保证风道组件200内的水均从排水管290排出。
翻边150的局部位置向上延伸形成定位部151，相邻两个定位部151用于限位排水板100上方的加热器240，加热器240的固定方式简单，且排水板100的结构简单。
上述实施例中，排水板100的形状与蒸发器230以及风道组件200的形状相关，排水板100的形状不作限定。排水板100的形状可以为矩形、梯形圆形或其他形状。排水板100的上表面与下表面的形状相同。
上述实施例中的排水板100应用于风道组件200中，也就是，排水板100设于蒸发器230的下方，从前向后的方向，蒸发器230无需向下倾斜，解决了蒸发器230具有倾斜角度会损失间室内容积的问题，在保证风道组件200内换热效率的情况下，实现了小角度化霜排水，以及减小了风道组件200高度方向落差，有助于间室内容积最大化。
当然，在实际使用中，蒸发器230也可稍微向下倾斜，但即使蒸发器230不向下倾斜，也不会影响排水效果。
当上述实施例中的排水板100应用于上述的风道组件200、箱胆以及制冷设备，则上述的风道组件200、箱胆以及制冷设备具有上述排水板100的有益效果。
以上实施方式仅用于说明本公开，而非对本公开的限制。尽管参照实施例对本公开进行了详细说明，本领域的普通技术人员应当理解，对本公开的技术方案进行各种组合、修改或者等同替换，都不脱离本公开技术方案的精神和范围，均应涵盖在本公开的权利要求范围中。
