Description

一种电磁加热模块及衣物处理装置 技术领域
本发明属于衣物处理装置技术领域，具体地说，涉及一种电磁加热模块及衣物处理装置。
背景技术
现有具有加热功能的衣物处理装置，如洗衣机大多采用在外筒底部设置凹陷，并在所述凹陷中安装加热管等加热装置的方式实现加热洗涤水的目的。但加热装置设置在外筒内部，占用了外筒的空间，对洗衣机的容量造成了影响。同时，加热装置位于外筒内部与洗涤水直接接触，因此对其密封性能的要求很高。然而加热装置工作时，其自身与周围长期处于较高温度状态，一定程度上加快了密封件的老化，容易造成密封失效，导致洗涤水渗入加热装置内部，或从外筒上安装加热装置的安装口渗出的情况，进而造成安全隐患。
另一方面，在加热过程中，加热装置附近的局部环境温度相对较高，而洗衣机外壳内部其他位置温度较低，容易在外壳内壁上远离加热装置的位置产生冷凝水。洗衣机外壳的内壁上安装有导线，若长期处于潮湿环境下容易造成导线表面绝缘层的老化，可能造成打火放电的情况，轻则产生焦糊异味，重则造成安装隐患。
近年来，洗衣机行业均进行无孔内筒洗衣机的开发，不同于传统的洗衣机在洗涤过程中通过外筒盛水，内筒盛放衣物，其在内筒上不再设置脱水孔，使得内筒在洗涤过程中可以独立盛放洗涤水。通过上述方式可以避免洗涤过程中内、外筒之间存水的情况，节省了洗涤水的用量，同时也很大程度上避免了内、外筒之间的脏污积累，从而避免了内、外筒之间的脏污进入内筒中污染衣物的情况，实现了洗衣干净卫生。但由于洗涤过程中内筒与外筒之间无水，无法通过传统洗衣机中在外筒内设置加热管的形式对洗涤水进行加热。
为解决上述一系列问题，现有技术中提出了在洗衣机中应用电磁加热模块加热洗涤水的方案。然而电磁加热模块在加热时本身温度较高，若不能实现有效散热，容易导致电磁加热模块过热发生故障，影响使用。目前避免电磁加热模块过热的一种方案是在电磁加热模块内部设置风扇，以加强空气流动，提高散热效率。另一种解决方案是采用高频云母线制成电磁加热线圈，由于高频云母线的耐高温性能较强，可以承受更高的工作温度，从而可以避免电磁加热模块发生过热故障。但上述两种方案均会导致电磁加热模块的制造成本上升，不利于推广应用。
有鉴于此，特提出本发明。

进一步地，还包括外筒，所述内筒设置在外筒内，所述电磁加热模块设置在外筒下方，与外筒的筒壁连接；
优选地，所述外筒的筒壁上设置凸筋，所述电磁加热模块安装于所述凸筋围成的区域内；
更优地，所述安装支架的底壁具有向安装支架的侧壁外周方向延伸形成的安装部，所述安装部上设置安装孔；所述凸筋围成的区域内设置与所述安装孔对应的螺钉柱。
进一步地，所述电磁加热模块具有朝向外筒筒壁的上表面，所述上表面为与所述内筒的筒壁共轴线的圆弧面；
优选地，所述电磁加热模块沿外筒周向的延伸长度大于其沿外筒径向的延伸长度。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明中，第二安装盘上的磁体可以起到屏蔽磁场的作用，防止磁场泄露，提高加热效率。通过设置第一安装盘和第二安装盘，并将线圈与磁体安装在两者相背的表面上，可以增大两者之间的距离，有利于线圈的散热，避免了电磁加热模块出现过热故障。第一安装盘与第二安装盘均具有镂空结构，可以增加线圈与空气的接触面积，同时增强电磁加热模块内部的空气流动，从而提高电磁加热模块的散热效率。环形加强筋的设置使多个线圈支撑部连接为一体，提高了第一安装盘整体的强度。第一安装盘上的线圈支撑部与第二安装盘上的磁体安装部在周向上重合，使得第一安装盘与第二安装盘的镂空区域重合，进一步增强了电磁加热模块内部的空气流通，提高了散热效率。第一安装盘与第二安装盘间隔设置，使得两者相对的表面之间可以存在空气流动，散热效果更好。
本发明中，线圈设置在封装壳体内部以防止与洗涤水直接接触，通过设置散热结构连通封装壳体内外空间，使封装壳体内部可以存在空气流通，从而实现线圈的有效散热。挡水结构环绕散热结构设置，防止水经散热结构进入封装壳体内部，防水效果好，避免了线圈与水接触造成短路故障的情况。散热孔设置在封装壳体的下表面，水从散热孔进入的风险小，下表面局部凸起形成挡水结构，结构简单且挡水效果好。位于散热孔外周的下表面凸起形成挡水结构，封装壳体的下表面上可能存在的水被挡水结构阻挡不会流至散热孔处进入封装壳体内部。封装壳体的下表面外周凸起形成挡水凸缘，封装壳体表面可能存在的水可沿挡水凸缘外侧直接滴落，而不会流动至散热孔所在的下表面，进而也不会经散热孔进入封装壳体内部，可实现有效的防水。
本发明中，在线圈的内周设置屏蔽磁感线的内磁钢，可减少磁感线在镂空区域内的辐射，使电磁加热模块产生的磁场集中向垂直于线圈表面的方向辐射，从而减少了磁场的泄露，提高了加热效率。内磁钢充满线圈内周的镂空区域，还可以对磁场起到均布作用，使镂空区域 处产生更加均匀的磁场，改善加热效果。片状的内磁钢将线圈内侧的镂空区域填满，对磁场的屏蔽效果更好，同时也避免了磁场在镂空区域边缘过度集中的情况。内磁钢与线圈的上表面平齐，使电磁加热模块的上表面整体平整，更容易装配于衣物处理装置中。隔离框架的设置避免了内磁钢与线圈接触造成影响，同时还可以对线圈起到支撑作用。线圈的内周与外周分别贴合于隔离框架的外周与安装支架的侧壁，确保了线圈作用面积的最大化。隔离框架内部的加强筋可防止隔离框架发生变形，使其结构更加稳定。隔离框架通过设置在加强筋两端延伸部上的卡爪固定于安装支架上，不易脱落，整体结构稳定。底面磁钢的设置使线圈产生的磁场集中向线圈一侧表面辐射，更加集中，线圈外周设置的外磁钢可对向线圈外周侧辐射的磁感线起到屏蔽作用，进一步减少了磁场的泄露，使产生的磁场集中辐射至被加热装置。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

实施例一
如图1至图6所示，本实施例提供一种电磁加热模块400和包括该电磁加热模块400的衣物处理装置。
如图1至图5所示，本实施例的电磁加热模块400包括：
第一安装盘410，所述第一安装盘410的上表面设置线圈401；
第二安装盘420，设置在第一安装盘410下方，所述第二安装盘420背向第一安装盘410的表面上安装磁体402。
本实施例中，第一安装盘410上的线圈401可在通入高频交流电时产生高频交变磁场，将其安装于衣物处理装置内部，可通过产生的高频交变磁场在金属材质的衣物处理筒或其他盛水容器中激发涡流效应，使衣物处理筒或其他盛水容器自身发热，从而实现无接触条件下对水的加热。
第一安装盘410和第二安装盘420均由绝缘材料制成，不受磁场的影响。第二安装盘420上的磁体402具有屏蔽磁场的作用，可以阻挡大部分向下辐射的磁场，减少了线圈401产生的磁场中穿透第二安装盘420的部分，使产生的磁场几乎全部向上辐射。如此可以使产生的高频交变磁场更加集中，提高了其对衣物处理筒的加热效率。
将线圈401与磁体402分别安装在第一安装盘410与第二安装盘420相背的表面上，可以增大两者之间的距离，有利于线圈401的散热，避免了电磁加热模块400出现过热故障，影响使用。
本实施例中，第一安装盘410与第二安装盘420均具有圆形外廓，线圈401在第一安装盘410的上表面呈螺旋状绕制，形成若干与第一安装盘410共圆心的同心圆。磁体402为条形磁体402，条形磁体402沿第二安装盘420的径向设置，安装在第二安装盘420的下表面。
具体地，线圈401由表面包覆绝缘层的铜导线绕制形成，相邻两圈铜导线之间接触盘绕或留有细小的间隔，最外圈接近第一安装盘410的外周。
优选地，在第二安装盘420的周向上间隔设置多个条形磁体402，多个条形磁体402在周向上均匀分布。
在上述方案中，螺旋绕制形成若干同心圆的线圈401有利于产生均匀的磁场，从而可以实现对衣物处理筒的均匀加热。在第二安装盘420周向上间隔设置多个条形磁体402，可在线圈401下方起到均匀的屏蔽效果，从而使辐射至衣物处理筒的磁场更加均匀。
本实施例的进一步方案中，第一安装盘410包括第一外环411，以及从第一外环411内侧沿径向延伸设置的若干线圈支撑部412。相邻的线圈支撑部412之间镂空设置。
在上述方案中，线圈支撑部412用于固定线圈401，相邻线圈支撑部412之间的镂空结构使得线圈401位于两个线圈支撑部412之间的部分上、下表面均与空气直接接触，增加了线圈401与空气的接触面积，提高了散热效率。
本实施例中，第一安装盘410的中央部分设置第一固定圆盘413，线圈支撑部412的延伸末端与第一固定圆盘413连接。通过设置第一固定圆盘413用于支撑线圈支撑部412的延伸末端，增强了第一安装盘410的整体强度，避免了线圈支撑部412靠近第一外环411圆心处在外力作用下容易折断的情况。
具体地，第一固定圆盘413与第一外环411共圆心设置，线圈支撑部412的延伸末端所在圆周的直径小于第一固定圆盘413的直径，也即线圈支撑部412延伸至第一固定圆盘413的内部。第一固定圆盘413的上表面与线圈支撑部412延伸末端的底面连接，相较于将线圈支撑部412端部直接固定在第一固定圆盘413外周的连接方式，接触面积更大，连接更加牢固。
本实施例中，为实现线圈401的固定，线圈支撑部412上沿其延伸方向间隔设置若干固定槽417(图中仅示出靠近外端部的固定槽417)，线圈401设置在固定槽417中。
优选地，线圈支撑部412包括沿径向延伸的支撑部底壁415，以及从支撑部底壁415的两侧边沿向上延伸形成的支撑部侧壁416，固定槽417从两侧的支撑部侧壁416上边沿贯通至支撑部底壁415。
更优地，支撑部底壁415靠近第一外环411的一端向上延伸形成支撑部端壁418，支撑部端壁418与第一外环411的内侧表面连接。
在上述方案中，形成线圈401的铜导线呈螺旋状绕制，经过线圈支撑部412时卡入固定槽417中，从而固定在第一安装盘410上。为保证对线圈401的固定效果，固定槽417可与形成线圈401的铜导线过盈配合，也即固定槽417在径向上的宽度略小于铜导线的直径，使得铜导线可以牢固地卡入固定槽417中，不易脱落。
线圈支撑部412垂直于径向的横截面呈U型，相邻两圈铜导线之间通过表面包覆的绝缘层实现绝缘，使得线圈支撑部412上无需设置隔开相邻两圈铜导线的隔板，也即其内部可在延伸方向上贯通，只需在支撑部侧壁416上开设固定槽417即可，线圈支撑部412的结构更加简单。
在线圈支撑部412靠近第一外环411的端部设置支撑部端壁418，用于与第一外环411内侧表面连接，采用面接触的连接方式增大连接面积，连接更加牢固。
本实施例的进一步方案中，第一安装盘410还包括与多个线圈支撑部412连接的加强部。
具体地，所述加强部为与第一外环411共圆心的环形加强筋414，多个线圈支撑部412的中部通过环形加强筋414连接为一体。
优选地，环形加强筋414从线圈支撑部412的下表面向下延伸形成。
在上述方案中，环形加强筋414的设置将多个线圈支撑部412连接为一体，对线圈支撑部412悬空的中部起到了支撑作用，进一步提高了第一安装盘410整体的强度。
本实施例中，环形加强筋414与第一外环411共圆心设置，位于第一外环411与第一固定圆盘413的外周之间，使得线圈支撑部412的两端及中部均得到了支撑，结构更加稳定。线圈401设置在第一外环411与环形加强筋414之间的区域，除去安装于线圈支撑部412上的部分，其余部分的上、下表面均暴露于空气中，散热效果好。
本实施例中第二安装盘420的结构与第一安装盘410类似。具体地，第二安装盘420包括第二外环421，以及从第二外环421内侧沿径向延伸设置的若干磁体安装部422。相邻的磁体安装部422之间镂空设置。
在上述方案中，第二安装盘420也具有镂空结构，使得电磁加热模块400至少部分区域上下贯通，更有利于空气流通，进一步提高了电磁加热模块400的散热效率。
本实施例的优选方案中，第二安装盘420的中央部分设置第二固定圆盘423，磁体安装部422的延伸末端与第二固定圆盘423连接。具体地，第二固定圆盘423与第二外环421共 圆心设置，磁体安装部422延伸至第二固定圆盘423的内部，第二固定圆盘423的下表面与磁体安装部422延伸末端的顶面连接。采用面接触的方式增大接触面积，连接更加牢固。
本实施例中，磁体安装部422包括沿径向延伸的安装部底壁425，以及从安装部底壁425的两侧边沿向下延伸形成的安装部侧壁426。条形磁体402安装在安装部底壁425与两侧的安装部侧壁426围成的空间内。
磁体安装部422垂直于径向的横截面呈U型，条形磁体402安装于磁体安装部422内，从而在线圈401下方呈放射状分布，对磁场的屏蔽效果好。为确保条形磁体402的稳定安装，条形磁体402可采用过盈配合的方式设置在磁体安装部422内，也即条形磁体402的宽度略大于磁体安装部422朝下开口的宽度。
本实施例的进一步方案中，多个磁体安装部422与线圈支撑部412在周向上至少部分重合设置。
优选地，多个磁体安装部422与线圈支撑部412在周向上一一对应重合。
磁体安装部422与线圈支撑部412在周向上重合，也即第一安装盘410与第二安装盘420上的镂空区域重合设置，使得电磁加热模块400中上下贯通的区域面积最大化，对空气流通的增强效果更好，尽可能提供了更优的散热效果。
本实施例中，第一安装盘410和第二安装盘420可以分体设置，通过连接结构组装为一体。具体地，第一安装盘410上设置连接孔，第二安装盘420上设置连接部424，连接部424插设在所述连接孔中，连接第一安装盘410与第二安装盘420。
优选地，所述连接孔设置在第一固定圆盘413的圆心处，连接部424从第二固定圆盘423的圆心处向上凸起插入所述连接孔中。
本实施例中，连接孔和连接部的设置位置还可以互换，也即第二安装盘上设置连接孔，第一安装盘上设置连接部，也可以实现第一安装盘与第二安装盘的连接。
本实施例的另一种方案中，第一安装盘410和第二安装盘420为一体结构，如采用一体注塑成型的方式制成连接为一个整体的第一安装盘410和第二安装盘420。
本实施例的进一步方案中，第一安装盘410与第二安装盘420相对的表面之间具有一定间隔。将第一安装盘410与第二安装盘420间隔设置，两者之间具有可使空气流通的间隙，可以进一步提高电磁加热模块400的散热效率。
本实施例中，第一安装盘410的下表面设置向下延伸形成的环形加强筋414。若采用分体设置的第一安装盘410和第二安装盘420，当第一安装盘410与第二安装盘420组装为一体时，环形加强筋414止抵于第二安装盘420的上表面，对第二安装盘420进行限位，保证第一安装盘410和第二安装盘420之间留有供空气流通的间隙。
若采用一体注塑成型的方式制成第一安装盘410与第二安装盘420，第一安装盘410与第二安装盘420可通过环形加强筋414一体地连接，且环形加强筋414的高度即为第一安装盘410和第二安装盘420之间的间隙高度。
本实施例中，在第一安装盘410和/或第二安装盘420的外周上设置固定部430，固定部430上开设固定孔431，电磁加热模块400可通过固定部430上的固定孔431安装在衣物处理装置内部，如安装于洗衣机的外筒的筒壁上，进而通过通入高频交流电激发内筒产生涡流效应，实现加热洗涤水的目的。
本实施例的方案中，电磁加热模块400包括分别用于安装线圈401和磁体402的第一安装盘410和第二安装盘420，两者间隔设置，并将线圈401和磁体402安装于相背的表面上，使得线圈401下方可存在空气流动，保证了线圈401的散热效果。第一安装盘410和第二安装盘420均具有镂空结构，使得电磁加热模块400上部分区域上下贯通，进一步提高了线圈401与空气的接触面积，增强了空气流动效果，使得电磁加热模块400具有较高的散热效率，应用于洗衣机中用于加热洗涤水时，不易发生过热故障导致影响使用，改善了用户体验。
本实施例所述的衣物处理装置包括但不限于洗衣机、洗干一体机等。如图6所示，本实施例的衣物处理装置包括外筒200和内筒，所述内筒设置在外筒200内，内筒的筒壁由可在 交变磁场中产生涡流的金属材料制成。
优选地，本实施例衣物处理装置的内筒在洗涤时可独立盛放洗涤水。具体地，内筒的筒壁上不设置脱水孔，在洗涤过程中为封闭状态，可以独立盛放洗涤水。内筒的筒壁上设置排水孔，排水孔在洗涤过程中被密封组件封堵，在内筒达到一定转速时，密封组件可以在离心力的作用下打开排水孔，实现洗涤水的排出。外筒200的筒壁上设置与排水结构连通的排水口211，内筒排出的水进入外筒200中，再经由排水口211及排水结构排出衣物处理装置。
内筒的筒壁由金属材质构成，外筒200由在磁场中不激发涡流效应的塑料材质制成。外筒200的外部安装有电磁加热模块400。如图1和图6所示，衣物处理装置启动加热程序后，输入电压，如220V家用交流电，经过桥式整流器转变为直流电，再经过IGBT功率管转变为高频交流电，输入电磁加热模块400后，线圈401可产生高频交变磁场。所述高频交变磁场的电磁感应线可穿透外筒200，作用在金属材质的内筒上，使内筒在电磁感应作用下产生涡流，涡流克服内筒的内阻流动时完成电能向热能的转换，实现内筒发热，从而对其中的洗涤水进行加热。
在加热过程中，控制内筒在外筒200内部旋转，使内筒受热均匀，从而均匀传热给内筒中盛放的洗涤水，加热效果更好。在外筒200的底部设置温度传感器，当温度传感器检测到的温度达到设定温度时，也即洗涤水达到预定的洗涤温度，加热程序停止，电磁加热模块400停止加热。
本实施例的优选方案中，电磁加热模块400设置在外筒200的下方，与外筒200的筒壁连接。图6所示为本实施例衣物处理装置的仰视图，其中外壳100的底部区域被取下，以展示衣物处理装置的内部结构。外壳100的底面四角处设置底脚101，外筒200通过减震器300支撑在外壳100内部。电磁加热模块400的外周设置固定部430，固定部430上开设固定孔431，通过螺钉穿过固定孔431，将电磁加热模块400安装在外筒200的筒壁上。
由于洗涤水在内筒中位于内筒底部区域，也即旋转到底部的内筒与洗涤水直接接触，将电磁加热模块400安装在外筒200下方，可集中对内筒的底部区域进行加热，从而实现直接加热洗涤水的目的，加热效率更高。同时也避免了内筒被加热的区域不与洗涤水接触，温度升高过快，容易造成电磁加热模块400过热故障的问题。
本实施例的进一步优选方案中，电磁加热模块400设置在外筒200的筒壁上靠近外筒200的筒底的区域。
本实施例中，外筒200的筒壁包括靠近筒口一侧的外筒前部210，以及与筒底连接的外筒后部220。排水口211设置在外筒前部210，电磁加热模块400安装在外筒后部220。上述设置方式使得电磁加热模块400和排水口211均可设置在外筒200的筒壁上最低的区域，且两者之间互不干扰。
如图1至图6所示，本实施例中，电磁加热模块400安装时，第一安装盘410所在一侧朝向外筒200的筒壁进行安装。电磁加热模块400工作时，线圈401可产生高频交变磁场，以激发内筒产生涡流效应，进而发热以加热洗涤水。第二安装盘420上的磁体402可对产生的磁场起到屏蔽作用，从而防止磁场朝背向内筒的方向泄露，使得线圈401产生的磁场更加高效地作用在内筒上，提高了加热效率。
本实施例的衣物处理装置通过设置电磁加热模块400实现洗涤水的加热功能，实现了内筒与外筒200之间无水的衣物处理装置的洗涤水加热目的。电磁加热模块400设置在外筒200下方，衣物处理装置工作期间不与洗涤水接触，减少了线圈401接触洗涤水带来的安全隐患，同时可以对内筒底部与洗涤水接触的部分进行加热，加热效率更高。
实施例二
如图7至图9所示，本实施例为上述实施例一的进一步限定，所述的电磁加热模块400还包括设置在第一安装盘410上方的第一遮挡件，用于防止线圈401从第一安装盘410上脱出，以及设置在第二安装盘420下方的第二遮挡件，用于防止磁体402从第二安装盘420上脱出。
进一步地，所述第一遮挡件为覆盖于第一安装盘410上表面的上挡板，所述第二遮挡件为覆盖于第二安装盘420下表面的下挡板。
在上述方案中，通过上、下挡板分别对应覆盖第一安装盘410和第二安装盘420，使得线圈401被夹持于上挡板与第一安装盘410之间，同时磁体402被夹持于第二安装盘420与下挡板之间，对线圈401和磁体402起到夹持固定的作用，避免了线圈401或磁体402发生脱落的情况。
本实施例中，所述电磁加热模块400还包括连接所述上挡板和下挡板的侧壁446，所述上挡板、下挡板和侧壁446形成封装壳体440，将第一安装盘410与第二安装盘420包覆于封装壳体440内部。
具体地，封装壳体440包括第一壳体441和第二壳体442，第二壳体442包括底壁445，以及环绕底壁445一周的侧壁446。第一壳体441为板状，覆盖于第一安装盘410上方，形成所述上挡板。第二壳体442设置在第二安装盘420下方，其底壁445形成所述下挡板。第一壳体441与第二壳体442的侧壁446连接，将第一安装盘410与第二安装盘420包覆于内部。
上述方案中，封装壳体440由不受磁场激发的绝缘材料制成，对线圈401产生的磁场不产生影响。封装壳体440的设置一方面对线圈401和磁体402起到了固定作用，另一方面，还将线圈401包裹在内部，减少了线圈401与水接触造成短路故障的风险。
本实施例的进一步方案中，封装壳体440上设置连通封装壳体440的内外空间的散热结构，以及环绕所述散热结构设置的挡水结构。所述散热结构连通封装壳体440的内外空间，使封装壳体440的内外空间之间可以存在空气交换，从而提高了线圈401的散热效果。如此避免了封装壳体440的存在导致线圈401难以散热的情况，可防止电磁加热模块400出现过热故障。挡水结构环绕散热结构设置，可将水阻挡于挡水结构外部，防止水经散热结构进入封装壳体440内部，防水效果好，避免了线圈401与水接触造成短路故障的情况。
具体地，所述散热结构为设置在封装壳体400下表面上，也即底壁445上的散热孔443，散热孔443贯通底壁445设置。底壁445局部凸起，形成环绕散热孔443的挡水结构。散热孔443优选设置多个，分布在底壁445上，可进一步提高散热效率。
本实施例的一种方案中，位于散热孔外周的底壁向下凸起形成所述挡水结构。每个散热孔的外周向下凸起形成多个独立的挡水结构，将每个散热孔单独围起，如果有滴落至封装壳体表面的水，可能流至底壁表面，但不会进一步流入散热孔内，防水效果好。
本实施例的另一种方案中，所述挡水结构为从底壁445的外周向下凸起形成的挡水凸缘444。
在上述方案中，底壁445外周凸起形成挡水凸缘444，当有水滴落至封装壳体440表面时，水向封装壳体440的外周流动，进而可沿挡水凸缘444外侧直接向下流动滴落，而不会流动至散热孔443所在的底壁445表面，进而也不会经散热孔443进入封装壳体440内部，结构简单，可实现有效的防水。
本实施例的优选方案中，挡水凸缘444从下表面的外周向下表面的内侧倾斜设置，从而可以减小挡水凸缘444下边沿围成的区域面积，减少了滴落的水从下方飞溅至底壁445表面的可能性。
本实施例的电磁加热模块400装配时，先将安装有线圈401的第一安装盘410和安装有磁体402的第二安装盘整体固定在第一壳体441上，或固定在第二壳体442内部，再将第一壳体441扣合于第二壳体442的上方敞口处，优选在第一壳体441与第二壳体442的侧壁446连接处进行密封处理。
在本实施例中，固定部430可设置在第一壳体441和/或第二壳体442上。具体地，本实施例的固定部430凸起于侧壁446设置。将固定部430设置在封装壳体440的外周，安装时电磁加热模块400可尽量贴近安装表面，如尽量贴近外筒的筒壁安装，进而更靠近内筒，从而实现更高的加热效率。
本实施例中，通过设置封装壳体440将第一安装盘410和第二安装盘420整体包覆在内部，一方面对线圈401和磁体402起到了辅助固定的作用，防止线圈401和磁体402从第一安装盘410和第二安装盘420上脱落，另一方面将线圈401包裹在封装壳体440内部，避免了线圈401与水接触造成短路故障的情况。封装壳体440上开设散热孔443，实现封装壳体440内外的空气流通，从而提高线圈401的散热效果，防止出现过热故障。封装壳体440上还设置挡水凸缘444，挡水凸缘444从封装壳体440的下表面外周凸起形成，将下表面上设置的散热孔443环绕在挡水凸缘444内侧，防止了洗涤水从散热孔443进入封装壳体440内部，造成线圈401短路故障的情况。
如图10所示，本实施例还提供一种包括上述电磁加热模块400的衣物处理装置。本实施例所述的衣物处理装置与上述实施例一相比，区别在于电磁加热模块400的第一安装盘410和第二安装盘420被整体封装于封装壳体440内部，并通过设置在封装壳体440上的固定部430将电磁加热模块400安装在外筒200上，其他结构与实施例一均相同，不再赘述。
具体地，电磁加热模块400安装时，第一壳体441所在一侧朝向外筒200的筒壁进行安装。电磁加热模块400工作时，线圈401可产生高频交变磁场，以激发内筒产生涡流效应，进而发热加热洗涤水。第二安装盘420上的磁体402可对产生的磁场起到屏蔽作用，从而防止磁场朝背向内筒的方向泄露，使得线圈401产生的磁场更加高效地作用在内筒上，提高了加热效率。
散热孔443设置在封装壳体440背向外筒200筒壁的表面上，即使外筒200出现渗水，洗涤水也不容易经散热孔443进入封装壳体440内部。挡水凸缘444从封装壳体440下表面向下凸起，滴落至封装壳体440上的洗涤水向外周流动，进而可以沿挡水凸缘444的外侧表面直接滴落，不会越过挡水凸缘444流至封装壳体440的下表面，从而防止了洗涤水由散热孔443进入封装壳体440内部，造成线圈401短路故障的情况。
本实施例的衣物处理装置中，电磁加热模块400设置在外筒200下方，衣物处理装置工作期间不与洗涤水接触，并通过封装壳体440包裹线圈401，减少了线圈401接触洗涤水带来的安全隐患，同时可以对内筒底部与洗涤水接触的部分进行加热，加热效率更高。封装壳体440下表面设置散热孔443提高散热效率，同时通过挡水凸缘444防止洗涤水从散热孔443流入封装壳体440内部，使电磁加热模块400同时具有良好的散热及防水性能，保证了衣物处理装置加热程序的稳定运行。
实施例三
如图11至图17所示，本实施例提供一种用于衣物处理装置的电磁加热模块600，包括安装支架610，以及设置在安装支架610上的线圈601，线圈601为环形结构，线圈601的内周设有屏蔽线圈601产生磁感线的内磁钢603，内磁钢603充满线圈601内周所围成的镂空区域。
本实施例中，向线圈601中通入高频交流电时，线圈601可产生高频交变磁场，将电磁加热模块600安装于衣物处理装置中，产生的高频交变磁场能够在金属材质的衣物处理筒或其他盛水容器中激发涡流效应，使衣物处理筒或其他盛水容器自身发热，从而实现无接触条件下对水的加热。
安装支架610由不受磁场激发的绝缘材料，如塑料制成，不会对线圈601产生的磁场造成影响。内磁钢603具有磁性，可对磁场起到屏蔽效果，其设置于线圈601的内周侧，可减少从线圈601内周向镂空区域辐射的磁感线，也即减少了在线圈601所在平面上辐射的磁感线。通过内磁钢603的设置减少了磁场的泄露，从而提高了电磁加热模块600的加热效率。
将内磁钢603设置为充满线圈601内周侧的镂空区域，屏蔽效果更强，还可以对磁场起到均布作用。上述方案相比于仅在镂空区域边缘设置一圈磁钢的方案，避免了磁场在镂空区域边缘过度集中的情况，使镂空区域的整体范围内都可以产生较为均匀地向上下方向辐射的磁场，从而使电磁加热模块600产生的磁场更加均匀，有利于提供均匀的加热效果。
本实施例的进一步方案中，内磁钢603为片状结构，具有与所述镂空区域匹配的外廓。
优选地，内磁钢603匹配安装于所述镂空区域内，内磁钢603的上表面与线圈601的上 表面平齐。
在上述方案中，片状的内磁钢603将线圈601内侧的镂空区域填满，对磁场的屏蔽效果更好。内磁钢603与线圈601的上表面平齐，使电磁加热模块600的上表面整体平整，不存在明显的凸起和凹陷，更容易装配于衣物处理装置中。
本实施例中，线圈601的内周与内磁钢603的外周之间还设置隔离框架630，线圈601环绕隔离框架630的外周呈螺旋状绕制，线圈601的内周与隔离框架630的外周贴合。
优选地，内磁钢603的外周与隔离框架630的内周贴合设置。
在上述方案中，线圈601由表面包覆由绝缘层的铜导线绕制形成，隔离框架630的设置进一步避免了内磁钢603与形成线圈601的铜导线接触造成影响，同时还可以对线圈601起到支撑作用，保证线圈601结构的稳定。内磁钢603设置在隔离框架630围成的范围内，与隔离框架630的内周贴合，便于内磁钢603的定位与固定。
本实施例中，安装支架610包括底壁611与侧壁612，线圈601设置在底壁611与侧壁612围成的容纳槽内，优选线圈601的外周与安装支架610的侧壁612内侧贴合。线圈601的内周与外周分别贴合于隔离框架630的外周与安装支架610的侧壁612，可以使线圈601的作用面积最大化，从而进一步提高电磁加热模块600的加热效率。
本实施例的进一步方案中，隔离框架630具有一定长度，隔离框架630的内部设置加强筋631，加强筋631沿垂直于隔离框架630的长度方向延伸设置，两端与隔离框架630连接。
本实施例中的隔离框架630为塑料件，不受磁场影响。隔离框架630的左右两端为圆弧形，前后两侧具有一定延伸长度。为避免隔离框架630的前后两侧由于延伸长度较大，容易发生变形，在前后两侧之间设置若干加强筋631，用于支撑隔离框架630的前后两侧，使其结构更加稳定。线圈601在隔离框架630外周螺旋绕制，形成类似跑道的形状。
本实施例的优选方案中，加强筋631将隔离框架630内侧分隔为至少两个独立区域，内磁钢603包括至少两个磁钢片，一一对应的设置在所述的独立区域内。
如图13所示，在上述方案中，为保证加强筋631的作用效果，加强筋631的高度不低于隔离框架630的高度，使隔离框架630的上边沿至下边沿全部受到加强筋631的支撑，从而使得隔离框架630所围成的区域被加强筋631分隔为多个互不相连的独立区域。相应地，如图12所示，内磁钢603包括多个一一对应地设置在所述独立区域中的磁钢片，其具体包括设置在左右两端的一侧具有圆弧形外廓的两块磁钢片，以及设置在中部的近似矩形的两块磁钢片。
本实施例中，隔离框架630与加强筋631一体成型，制造工艺简单。
本实施例的进一步方案中，加强筋631的前后两端具有向安装支架610的底壁611方向延伸的延伸部632，延伸部632的延伸末端设置卡爪633。安装支架610的底壁611上对应卡爪633的位置设置卡槽613。
通过卡爪633和卡槽613卡接固定，使隔离框架630可固定于安装支架610上，不易脱落，然后再对线圈601与内磁钢603进行装配，电磁加热模块600的整体结构更加稳定。
优选地，安装支架610的底壁611上与加强筋631对应的位置设置条形通孔614，卡槽613设置在条形通孔614的两端。卡爪633插入条形通孔614中与卡槽613卡接固定，使卡爪633从安装支架610下方可视，当电磁加热模块600需要拆卸检修时，可从安装支架610下方经条形通孔614拨动卡爪633，使其与卡槽613脱离，从而取下隔离框架630。
本实施例的进一步方案中，线圈601与安装支架610的底壁611之间还设置底面磁钢602，底面磁钢602为片状结构，铺设在安装支架610的底壁611上。延伸部632贯穿底面磁钢602，使卡爪633与卡槽613卡接。
优选地，线圈601与底面磁钢602之间设置隔离层620，隔离层620的中部具有与线圈601的镂空区域匹配的贯通孔621。
在上述方案中，底面磁钢602的设置对向线圈601下方辐射的磁感线起到了屏蔽作用，使产生的磁场集中向上侧辐射，从而进一步减少了磁场的泄露，提高了加热效率。片状的底 面磁钢602将线圈601的下方空间铺满，加强了对磁场的屏蔽效果，进一步减少了向电磁加热模块600下方泄露的磁场。在底面磁钢602与线圈601之间设置绝缘复合材料制成的隔离层620，线圈601与底面磁钢602不直接接触，避免干扰。隔离层620中部设置贯通孔621，不影响隔离框架630的安装。
本实施例中，底面磁钢602包括多个铺设在安装支架610的底壁611上的磁钢片，相邻两个磁钢片之间具有一定间隙，延伸部632穿过所述间隙，使卡爪633与卡槽613卡接。
优选地，底壁611上设置插设于所述间隙中的分隔板615，分隔板615上与加强筋631的位置对应的区域具有避让缺口616。
在上述方案中，将底面磁钢602设置为多个独立的磁钢片，装配时在相邻两个磁钢片之间留有供延伸部632穿过的间隙，从而不需要在底面磁钢602上额外开孔，简化了制造工艺。底壁611上的分隔板615可在装配时辅助底面磁钢602的定位，装配更加容易。部分分隔板615上设置避让缺口616，供延伸部632穿过。
本实施例中，底面磁钢602包括六块磁钢片，具体为设置在左右两端的两块一侧具有半圆外廓的磁钢片，以及设置在中间的四块近似矩形的磁钢片。分隔板615在底壁611上等间距的设置五个，中间三个分隔板615与隔离框架630上的加强筋631位置对应并设置避让缺口616。
本实施例的进一步方案中，线圈601的外周设有屏蔽线圈601产生磁感线的外磁钢604。具体地，安装支架610的侧壁612上设置用于安装外磁钢604的安装槽617，外磁钢604放置于安装槽617中。
优选地，侧壁612具有一定厚度，安装槽617设置在侧壁612的内周与外周之间，安装槽617的开口设置于侧壁612的上表面。
在上述方案中，设置在线圈601外周的外磁钢604可对向线圈601外周侧辐射的磁感线起到屏蔽作用，进一步减少了磁场的泄露，使产生的磁场更加集中地向电磁加热模块600上侧辐射。
本实施例中，外磁钢604包括多个磁钢块，具体包括环绕线圈601左右两端圆弧外廓的多个小磁钢块，以及设置在线圈601前后两侧的两个条形磁钢块。为进一步方便加工，两个条形磁钢块还可以设置为由若干长度更短的磁钢块组成。安装支架610上设置与多个磁钢块一一对应的安装槽617。
本实施例中，线圈601连接的接线端子(图中未示出)从安装支架610的侧壁612穿出电磁加热模块600，侧壁612上对应位置开设出线孔(图中未示出)，相应地，与出线孔对应的位置不安装外磁钢604。
本实施例的进一步方案中，电磁加热模块600的上表面为圆弧面，将其应用于衣物处理装置中加热衣物处理筒时，避免了电磁加热模块600左右两端与中部和衣物处理筒之间的距离相差过多，导致加热效率不同的情况，有利于实现更加均匀的加热效果。
底面磁钢602与内磁钢603均由多个磁钢片组合而成，使每个磁钢片可以近似为平板结构，相较于制造一整块具有弧度的磁钢片，多个平板结构的磁钢片更容易加工成型。
本实施例中，安装支架610的底壁611具有向安装支架610的侧壁612外周方向延伸形成的安装部618，安装部618上设置安装孔619。安装部618从侧壁612上圆弧段与近似直线段的连接处向左右两端延伸，使底壁611整体呈近似矩形。电磁加热模块600可通过安装部618上的安装孔619安装在衣物处理装置内部，如安装于洗衣机的外筒的筒壁上，进而通过通入高频交流电激发内筒产生涡流效应，实现加热洗涤水的目的。
本实施例中，电磁加热模块600的各部分均通过模具加工而成。
具体地，安装支架610、隔离层620和隔离框架630分别在不同的模具中一体注塑成型。
底面磁钢602需两套加工模具，分别用于制造两端的磁钢片和中间的多个磁钢片。内磁钢603需两套加工模具，分别用于制造两端的磁钢片和中间的两个磁钢片。外磁钢604也需要两套加工模具，分别用于制造环绕左右两端的多个小磁钢块，以及前后两侧的两个条形磁 钢块。
线圈601也可以在铜导线绕制完成后放入对应的模具中，然后注入封装材料进行封装，脱模后得到线圈601被封装材料完全包覆的环形一体结构，一方面便于后期装配，另一方面也大大提高了线圈601的防水性能。
装配时，先将底面磁钢602铺设在安装支架610的底壁611上，将外磁钢604一一对应地放入各个安装槽617中。然后在底面磁钢602上放置隔离层620，并安装隔离框架630。之后再将线圈601与内磁钢603分别放置与隔离框架630的外侧与内侧，即完成了电磁加热模块600的装配。
进一步地，本实施例中电磁加热模块600的各个部件之间通过胶结固定。具体地，采用工作温度范围约为-50～200℃的硅酮胶粘接各个部件，可以耐受电磁加热模块600工作时的高温环境，使电磁加热模块600中各个部件之间的连接更加牢固。
本实施例的电磁加热模块600在线圈601的下方、内周侧以及外周侧均设置可屏蔽磁场的磁钢，底面磁钢602、内磁钢603和外磁钢604相互配合，可以起到有效的防止磁场泄露的作用，使线圈601产生的磁场集中向电磁加热模块600上方辐射，以提高加热效率。通过对电磁加热模块600的结构设计，使电磁加热模块600的整体结构更加稳定，产生的磁场更加均匀，有利于提供均匀的加热效果。
如图11至图20所示，本实施例还提供一种衣物处理装置，包括上述电磁加热模块600。
本实施例所述的衣物处理装置包括但不限于洗衣机、洗干一体机等。具体地，所述的衣物处理装置包括内筒(图中未示出)，所述内筒的至少部分由可在交变磁场中产生涡流的金属材料制成。
详细地，电磁加热模块600设置在内筒下方，内筒的筒壁至少部分由金属材料制成，金属材料制成的部分筒壁在电磁加热模块600的激发下产生涡流效应而发热，进而对内筒中的洗涤水进行加热。优选地，内筒的筒壁全部由金属材料制成，在内筒转动过程中，筒壁的各个部分转动到靠近电磁加热模块600的位置时，都可受到电磁加热模块600的激发而发热，从而可以实现更高的加热效率。
本实施例的另一种方案中，内筒的筒壁可以由绝缘材料制成，而在内筒的筒壁上设置由金属材料制成的提升筋或其他附加模块，所述提升筋或其他附加模块在电磁加热模块600的激发下发热，对内筒中的洗涤水起到加热作用。
本实施例的衣物处理装置还包括外筒500，所述内筒设置在外筒500内。优选地，本实施例衣物处理装置的内筒在洗涤时可独立盛放洗涤水。具体地，内筒的筒壁上不设置脱水孔，在洗涤过程中为封闭状态，可以独立盛放洗涤水。内筒的筒壁上设置排水孔，排水孔在洗涤过程中被密封组件封堵，在内筒达到一定转速时，密封组件可以在离心力的作用下打开排水孔，实现洗涤水的排出。外筒500与排水结构连通，内筒排出的水进入外筒500中，再经由排水结构排出衣物处理装置。
本实施例中，内筒的筒壁由金属材质构成，外筒500由在磁场中不激发涡流效应的塑料材质制成。外筒500的外部安装电磁加热模块600，向其内部的线圈601通入高频交流电后可产生高频交变磁场。所述高频交变磁场的电磁感应线可穿透外筒500，作用在金属材质的内筒筒壁上，使内筒的筒壁在电磁感应作用下产生涡流，涡流克服内筒筒壁的内阻流动时完成电能向热能的转换，实现内筒筒壁的发热，从而对其中的洗涤水进行加热。
本实施例的进一步方案中，电磁加热模块600设置在外筒500下方，与外筒500的筒壁510连接。
优选地，外筒500的筒壁510上设置凸筋511，电磁加热模块600安装于凸筋511围成的区域内。具体地，凸筋511在外筒500的筒壁510底部围成矩形区域，用于安装电磁加热模块600。
在上述方案中，电磁加热模块600设置在外筒500下方，衣物处理装置工作期间不与洗涤水直接接触，减少了线圈601与水接触带来的安全隐患。另一方面，电磁加热模块600可 集中对内筒的底部区域，也即洗涤水集中的部分加热，加热效率更高。
电磁加热模块600的安装支架610上设置安装部618，安装部618上开设安装孔619。凸筋511围成的区域内设置与电磁加热模块600上的安装孔619对应的螺钉柱512，螺钉柱512具体设置在凸筋511内侧区域的四个顶角处，通过螺钉穿过安装孔619旋入螺钉柱512中，将电磁加热模块600固定在外筒500的筒壁510上。
本实施例的进一步方案中，电磁加热模块600的上表面朝向外筒500的筒壁510安装，所述上表面为与内筒的筒壁共轴线的圆弧面。如此可以使电磁加热模块600的上表面上各处与内筒的筒壁间的距离均相等，进而使内筒的筒壁均匀受热。
本实施例的优选方案中，电磁加热模块600沿外筒500周向的延伸长度大于其沿外筒500径向的延伸长度。电磁加热模块600通过沿外筒500的周向延伸以增大加热面积，从而无需在外筒500径向上占据较大面积。
本实施例中，电磁加热模块600安装在外筒500的筒壁510最低处以实现最优的加热效果，而一些其他结构，如外筒500上的排水口也需要设置在筒壁510的最低处。通过减少电磁加热模块600沿外筒500径向的延伸长度，可避免其在外筒500的筒壁510最低处占用过多空间，影响排水口等结构的设置。而电磁加热模块600在外筒500周向上延伸以提供更大的加热面积，从而可以达到更高的加热效率。
本实施例的衣物处理装置通过设置电磁加热模块600实现洗涤水的加热功能，实现了内筒与外筒500之间无水的衣物处理装置的洗涤水加热目的。电磁加热模块600设置在外筒500下方，衣物处理装置工作期间不与洗涤水接触，减少了线圈601接触洗涤水带来的安全隐患，同时可以对内筒底部与洗涤水接触的部分进行加热，加热效率更高。电磁加热模块600具有朝上的圆弧表面，使上表面与内筒的筒壁表面平行，可以起到均匀的加热效果。电磁加热模块600在外筒500的周向延伸以提供更大的加热面积，在外筒500的径向上不具有过长的延伸长度，避免在外筒500的筒壁510最低处占用过多空间。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
