Description

一种电磁加热模块、制造工艺及衣物处理装置 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、制造工艺及衣物处理装置。
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
同时，现有的电磁加热模块一般在支架上设置固定结构，如绕线槽等，在装配时需将电磁加热线圈，以及起屏蔽磁场作用的磁体通过固定结构安装在支架上。如此导致电磁加热模块的结构复杂，装配工序繁琐，而电磁加热线圈与磁体后期安装于支架上，在衣物处理装置工作过程中产生的震动可能会造成电磁加热线圈或磁体从支架上脱落，影响电磁加热模块的使用。
再者，电磁加热模块应用于洗衣机中时，存在与洗涤水接触的风险，可能导致电磁加热线圈短路故障，甚至造成安全隐患。现有的防水方式多采用塑料外壳将电磁加热线圈完全包覆，然而由于需要将电磁加热线圈放置于塑料外壳内部，塑料外壳均为分体式设置，组装后再对连接处进行密封处理。但长期使用后，密封件容易出现老化而导致密封性能下降甚至失效，进而造成防水性能的丧失，容易导致电磁加热线圈与水接触发生短路故障。
有鉴于此，特提出本发明。

更优地，所述电磁加热模块设置在外筒的筒壁上靠近外筒的筒底的区域。
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，电磁加热线圈与磁体分别设置在板状结构的支架两侧表面，电磁加热线圈的一侧表面直接暴露于空气中，具有良好的散热效果。另一侧的磁体可以起到屏蔽磁场的作用，防止磁场泄露，从而使电磁加热线圈产生的磁场更高效地作用在被加热的盛水容器上，提高加热效率。电磁加热线圈和/或磁体部分嵌入支撑部的表面，增加了电磁加热线圈及磁体与支撑部的接触面积，使得电磁加热线圈和磁体在支撑部上的固定更加牢固，避免了电磁加热线圈或磁体从支撑部上脱落的情况。
本发明中，由料片，例如橡胶料片、预浸树脂的纤维料片、团状或片状模塑料等固化成型形成支架，电磁加热线圈和磁体与料片一同放入模具中，在料片表面材料的固化过程中，电磁加热线圈和磁体可与料片表面的材料粘连为一体，进而在料片固化成型后直接固定在形成的支架表面，省去了复杂的装配工艺，使制造工艺大幅度简化。
本发明中，通过封装体完全包覆电磁加热线圈，避免了电磁加热线圈与水接触的风险，具有可靠的防水效果，从而避免了电磁加热线圈与水接触造成短路故障，影响电磁加热模块工作的情况。电磁加热线圈呈螺旋绕制形成若干同心圆，有利于产生分布较为均匀的磁场，从而在衣物处理装置中，对被加热的盛水容器产生均匀的加热效果。封装体内部的磁体可以起到屏蔽磁场的作用，防止磁场泄露，从而使电磁加热线圈产生的磁场更高效地作用在被加热的盛水容器上，提高加热效率。电磁加热线圈与磁体间隔设置，两者之间被形成封装体的材料填充，避免了磁体与形成电磁加热线圈的导线接触造成影响。电磁加热线圈与磁体分别靠近封装部的表面设置，使电磁加热线圈与磁体在被封装部包覆的情况下尽量接近外部空间，有利于提高电磁加热模块，尤其是内部电磁加热线圈的散热效率。
本发明中，由绝缘材料固化成型形成包覆电磁加热线圈和磁体的封装体，使电磁加热模块可以一体成型，制造工艺简单，无需复杂的装配工序。绝缘材料分多次进行加热处理，使得磁体或电磁加热线圈放入模具中时，已注入模具中的绝缘材料已固化形成固态，从而可以将磁体或电磁加热线圈稳定地放置在已固化的绝缘材料表面，保证磁体与电磁加热线圈在封装体中的嵌入位置，避免绝缘材料未完全固化前磁体或电磁加热线圈在绝缘材料中下沉，未能保持在理想的嵌入位置的情况。
本发明的衣物处理装置中安装电磁加热模块，实现了对内筒中所盛水的无接触加热。电磁加热模块设置在外筒下方，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。另一方面，衣物处理装置工作期间电磁加热模块不与水直接接触，进一步减少了电磁加热线圈与水接触带来的安全隐患。
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4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400，包括板状结构的支架404，支架404的一侧表面上固定设置电磁加热线圈401，另一侧表面上固定设置磁体402。电磁加热线圈401和磁体402在支架404成型过程中固定在支架404的表面。
本实施例中，固定于支架404上侧表面的电磁加热线圈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。支架404由不受磁场激发的绝缘材料制成，不会在电磁加热线圈401的作用下发热，也不会对电磁加热线圈401产生的磁场造成影响。
支架404下侧表面上固定的磁体402具有屏蔽磁场的作用，可以阻挡大部分向下辐射的磁场，减少了电磁加热线圈401产生的磁场中向下辐射的部分，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。通过支架404将电磁加热线圈401与磁体402隔开，两者互不接触，避免磁体402与形成电磁加热线圈401的导线接触造成影响。
同时，电磁加热线圈401与磁体402分别设置在板状结构的支架404的上、下两侧表面，电磁加热线圈401的上侧表面直接暴露于空气中，从而具有良好的散热效果。支架404为板状结构，使得电磁加热模块400整体具有较小的厚度和较大的加热面积，加热效率高，占用空间小，有利于节省衣物处理装置内部空间。
另一方面，电磁加热线圈401和磁体402在支架404成型的过程中与直接固定在支架404表面，无需设置复杂的安装结构用于固定电磁加热线圈401和磁体402，或者通过额外的工艺步骤对电磁加热线圈401和磁体402进行固定，简化了制造工艺流程。
本实施例的进一步方案中，支架404包括成圆盘结构的支撑部460，电磁加热线圈401在支撑部460一侧表面呈螺旋状绕制，形成若干与支撑部460共圆心的同心圆。磁体402为条形磁体402，沿支撑部460的径向设置，固定在支撑部460的另一侧表面。
具体地，电磁加热线圈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，最外圈铜导线所环绕圆周的直径尽量接近支撑部460的外周直径。
优选地，在支撑部460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电磁加热线圈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。在支撑部460周向上间隔设置多个条形磁体402，可在电磁加热线圈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，电磁加热线圈401部分嵌入支撑部460的一侧表面；和/或，磁体402部分嵌入支撑部460的另一侧表面。
在上述方案中，电磁加热线圈401和/或磁体402部分嵌入支撑部460的表面，可增加电磁加热线圈401及磁体402与支撑部460的接触面积，从而使电磁加热线圈401和磁体402更加牢固地固定在支撑部460上，避免了电磁加热线圈401或磁体402从支撑部460上脱落的情况。
具体地，本实施例中，支架404由料片固化成型制成，电磁加热线圈401和磁体402在料片固化成型前放置于料片两侧合适位置，料片表面的材料在固化前具有一定流动性，可包裹电磁加热线圈401的下表面以及磁体402的上表面，还可以渗透进入电磁加热线圈401中相邻两圈铜导线之间的缝隙。固化成型后，电磁加热线圈401的底部以及磁体402的顶部被形成支架404的材料包裹，从而牢固地固定在支撑部460表面，不易脱落。
本实施例中，支架404还包括固定部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筒壁上，进而通过通入高频交流电激发外筒内的内筒生涡流效应，实现加热洗涤水的目的。
具体地，固定部430设置在支撑部460的外周，从而可以在安装电磁加热模块400时，使电磁加热模块400尽量贴近安装表面，也即外筒的筒壁，进而更加靠近被加热的内筒，具有更高的加热效率。
本实施例中，通过板状结构的支架404固定电磁加热线圈401和磁体402形成电磁加热模块400，电磁加热线圈401和磁体402分别位于支架404两侧表面，电磁加热线圈401的上表面直接暴露于空气中，从而可以达到较高的散热效率，避免电磁加热模块400出现过热故障，影响使用。电磁加热模块400整体为薄板形状，可以在提供一定的加热面积的情况下节省其占用的空间，避免电磁加热模块400的设置影响衣物处理装置内其他元件的安装。
实施例二
如图1至图4所示，本实施例提供了一种上述实施例一所述的电磁加热模块400的制造工艺，包括：
在模具中分别放入磁体402、料片与电磁加热线圈401，使电磁加热线圈401与磁体402分别位于料片的两侧；
所述料片固化成型形成支架404，使磁体402与电磁加热线圈401固定在支架404表面；
脱模，得到电磁加热模块400。
本实施例中，固化成型形成的支架404可能存在飞边、凸起等瑕疵，为提高电磁加热模块400的整体美观度，同时也避免所述瑕疵在后期将电磁加热模块400安装至衣物处理装置中时造成影响，例如固定孔431被封堵影响安装，可通过打磨修正消除所述瑕疵，使电磁加热模块400的表面更加平滑。
在上述方案中，电磁加热线圈401和磁体402与形成支架404的料片一同放入模具中，料片表面的材料，也即其与电磁加热线圈401和磁体402接触的部分在固化过程中与电磁加热线圈401和磁体402粘连为一体，进而在固化完成后可将电磁加热线圈401和磁体402固定在形成的支架404表面。电磁加热模块400在模具中一体成型，不需要后续的装配工序，或进行后续处理以固定电磁加热线圈401和磁体402，使制造工艺大幅度简化。
进一步地，所述料片为橡胶料片，所述橡胶料片经硫化处理后固化成型，形成支架404。
具体地，本实施例采用热硫化方式的使橡胶料片固化成型形成支架404，将未经硫化处理的橡胶料片裁剪成合适的形状与大小，使之与所要得到的支架404的形状与大小相似。然后在模具中依次放入磁体402，橡胶料片，以及电磁加热线圈401，使橡胶料片位于磁体402与电磁加热线圈401之间，合模，进行加热处理，必要时还进行加压处理。保持一定时间后，电磁加热线圈401和磁体402被粘连固定于橡胶料片的两侧表面，橡胶料片自身固化成型形成支架404。脱模后即可得到电磁加热线圈401和磁体402分别固定于支架404两侧表面的电磁加热模块400。
实施例三
如图1至图4所示，本实施例与上述实施例二的区别在于：所述料片为片状预浸料，所述片状预浸料经加热处理后热固化成型，形成支架404。
预浸料是指用树脂基体浸渍连续纤维或织物，制成树脂基体与增强体的组合物，一般作为制造复合材料的中间材料。
具体地，本实施例中，所述树脂基体选用环氧树脂，所述增强体选用碳纤维或玻璃纤维。 也即，所述片状预浸料为预浸环氧树脂的碳纤维或预浸环氧树脂的玻璃纤维。
详细地，以采用碳纤维布为例，对本实施例的制造工艺进行说明。
按照所需支架404的形状和大小进行剪裁，得到多片与支架404形状、大小基本吻合的碳纤维布，并预浸环氧树脂；或者，将碳纤维布预浸环氧树脂后再进行剪裁，得到多片预浸环氧树脂的碳纤维布；
将磁体402放入模具中的特定位置，然后将多片预浸环氧树脂的碳纤维布叠加在一起，放入模具中磁体402的上方；
将电磁加热线圈401放置于多片碳纤维布上方，合模；
对模具进行加热加压处理，使环氧树脂固化成型，将多片碳纤维布以及上、下两侧的电磁加热线圈401和磁体402连接为一体；
脱模，打磨修正，即得电磁加热模块400。
本实施例中，采用碳纤维或玻璃纤维与环氧树脂的复合材料制成支架404，其具有高强度与低密度，可保证电磁加热模块400具有足够的强度，不易损坏，同时电磁加热模块400的质量轻，不会造成衣物处理装置安装电磁加热模块400后重量显著增加。
实施例四
如图1至图4所示，本实施例与上述实施例一的区别在于：所述料片为团状模塑料(Bulk molding compounds,BMC)，所述团状模塑料在模具中经加压与加热处理后热固化成型，形成支架404。
BMC是一种热固定塑料，其中混合了各种惰性填料、纤维增强材料、催化剂、稳定剂和颜料。一般情况下，BMC主要由短切玻璃纤维、不饱和树脂、填料以及各种添加剂经充分混合而成。本实施例所采用的BMC即为玻纤增强不饱和聚酯热固性塑料。
本实施例中，BMC经压制成型工艺形成支架404。具体地，所述模具包括分体设置的两部分，两部分上分别设置容纳电磁加热线圈401和磁体402并对两者进行限位的空间，将磁体402与电磁加热线圈401分别对应放入位置，然后在磁体402上方放置待成型的BMC。合模，使模具的两部分扣合为一体，内部的BMC填充模具内的成型腔，以形成支架404的形状。对模具整体进行加压与加热处理，并在一定压力与温度下保持一定时间，BMC固化成型形成支架404，同时将电磁加热线圈401与磁体402固定在其表面。脱模，打磨修正，即得电磁加热模块400。
实施例五
如图1至图4所示，本实施例与上述实施例四的区别在于：所述料片为片状模塑料(Sheet molding compounds,SMC)，所述片状模塑料在模具中经加压与加热处理后热固化成型，形成支架404。
SMC是由树脂糊浸渍纤维或短切纤维毡，并在两边覆盖聚乙烯膜制成的一类片状模压料。使用时，将其按照一定形状与尺寸进行剪裁，然后揭去两侧的聚乙烯膜，叠放于模具中进行加温加压成型，脱模后即可得到所需形貌的制品。
本实施例中，先将磁体402放入模具中特定位置，然后根据支架404的厚度需求将剪裁好的一片或多片SMC放入模具中磁体402上方，最后再在SMC表面放置电磁加热线圈401。合模后，经加压与加热处理，SMC在模具内热固化成型，并将电磁加热线圈401和磁体402粘连固定在表面。脱模并进行打磨修正后，即得电磁加热模块400。
由于支架404本身为板状结构，可剪裁多片形状与尺寸相同的SMC叠放入模具的成型腔 中，使最终所得支架404与预期结构高度吻合。在本实施例中采用SMC作为形成支架404的料片，操作简单。
实施例六
如图5所示，本实施例提供一种衣物处理装置，包括上述实施例一所述的电磁加热模块400。
具体地，本实施例以洗衣机为例进行说明。所述的洗衣机包括外筒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，本实施例洗衣机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及排水结构排出洗衣机。
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5所示，洗衣机启动加热程序后，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中的电磁加热线圈401后，电磁加热线圈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5所示为本实施例洗衣机的仰视图，其中外壳100的底部区域被取下，以展示洗衣机的内部结构。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5所示，本实施例中，电磁加热模块400安装时，电磁加热线圈401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，电磁加热线圈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。电磁加热线圈401下方的磁体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，使得电磁加热线圈401产生的磁场更加高效地作用在内筒上，提高了加热效率。
电磁加热线圈401和磁体402分别固定在支架404的上、下表面，电磁加热线圈401的上侧表面直接暴露于空气中，从而具有良好的散热效果，可避免出现过热故障，影响电磁加热模块400的工作。电磁加热线圈401由表面包覆绝缘层的铜导线绕制形成，且电磁加热模块400安装于外筒200外部，一般情况下不接触洗涤水，即使外筒200出现渗水现象，渗出的水量较少，绝缘层的保护足以避免洗涤水造成短路故障的情况。
本实施例的洗衣机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之间无水的洗衣机的洗涤水加热目的。电磁加热模块400设置在外筒200下方，洗衣机工作期间不与洗涤水接触，电磁加热线圈401可直接设置在支架404朝向外筒200的表面，也即电磁加热线圈401的上表面可暴露与空气中，而不必担心洗涤水导致电磁加热线圈401短路的情况，使得电磁加热线圈401具有良好的散热效果，可有效避免发生过热故障的情况。
实施例七
如图6至图8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400，包括封装体403，以及嵌入封装体403内部的电磁加热线圈401，电磁加热线圈401的表面被封装体403完全包覆。
本实施例中，电磁加热线圈401可在通入高频交流电时产生高频交变磁场，将上述电磁加热模块400安装于衣物处理装置内部，可通过产生的高频交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。封装体403由不受磁场激发的绝缘材料制成，不会在电磁加热线圈401的作用下发热，也不会对电磁加热线圈401产生的磁场造成影响，同时还将电磁加热线圈401完全包覆，避免了电磁加热线圈401与水接触造成短路故障的风险，具有可靠的密封效果，实现了有效的防水。
本实施例的进一步方案中，封装体403包括呈圆盘结构的封装部450，电磁加热线圈401嵌入封装部450内部。电磁加热线圈401呈螺旋状绕制，形成若干与封装部450共圆心的同心圆。
具体地，电磁加热线圈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，最外圈铜导线所环绕圆周的直径尽量接近封装部450的外周直径。
在上述方案中，螺旋绕制形成若干同心圆的电磁加热线圈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。
本实施例的优选方案中，封装体403还包括固定部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。
具体地，固定部430凸起于封装部450的外周设置。将固定部430设置在封装部450的外周，安装时电磁加热模块400可尽量贴近外筒的筒壁，从而更加靠近被加热的内筒，进而实现更高的加热效率。
本实施例的进一步方案中，封装体403内部还嵌入磁体402，磁体402设置在电磁加热 线圈401下方，磁体402的表面被封装体403完全包覆。
优选地，封装体403具有一定厚度，电磁加热线圈401与磁体402在封装体403的厚度方向上间隔设置。
在上述方案中，电磁加热线圈401下方的磁体402具有屏蔽磁场的作用，可以阻挡大部分向下辐射的磁场，减少了电磁加热线圈401产生的磁场中向下辐射的部分，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。
电磁加热线圈401与磁体402在封装体403内部间隔设置，两者之间被形成封装体403的绝缘材料填充，避免了磁体402与形成电磁加热线圈401的导线接触造成影响。
本实施例中，磁体402嵌入封装体403的封装部450内部，磁体402为条形磁体402，条形磁体402沿封装部450的径向设置。
优选地，在封装部450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，在封装部450周向上间隔设置多个沿径向延伸的条形磁体402，可在电磁加热线圈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，封装部450具有靠近电磁加热线圈401的上表面，以及靠近磁体402的下表面。
电磁加热线圈401的上表面与封装部450的上表面之间的距离小于电磁加热线圈401与磁体402之间的间隔距离，磁体402的下表面与封装部450的下表面之间的距离小于电磁加热线圈401与磁体402之间的间隔距离。
在上述方案中，电磁加热线圈401与磁体402分别靠近封装部450的上、下表面设置，使电磁加热线圈401与磁体402在被封装部450包覆的情况下可以尽量接近外部空间，也即覆盖于电磁加热线圈401上表面，以及覆盖于磁体402下表面的绝缘材料厚度较薄，有利于提高电磁加热模块400，尤其是内部电磁加热线圈401的散热效率。
本实施例中，电磁加热模块400中的电磁加热线圈401被封装体403完全包覆，表面无缝隙，无需任何密封处理即可避免电磁加热线圈401与水接触的风险，且不会出现现有技术中密封件老化导致的密封失效情况，具有可靠的密封性能，能够实现有效的防水。通过对电磁加热线圈401与磁体402在封装体403内部的位置设计，使电磁加热线圈401在被完全包覆的情况下可尽量靠近电磁加热模块400表面，保证了电磁加热线圈401的散热效率，避免了过热故障。
实施例八
如图6至图9所示，本实施例提供了一种上述实施例七所述的电磁加热模块400的制造工艺，包括：
向模具500中注入绝缘材料，并放入电磁加热线圈401；
所述绝缘材料固化成型，形成包覆电磁加热线圈401的封装体403；
脱模，得到电磁加热模块400。
对于包括磁体402的电磁加热模块400，制造时在模具500中还放入磁体402，绝缘材料最终形成的封装体403包覆电磁加热线圈401和磁体402。
具体地，所述绝缘材料为热固性树脂，绝缘材料经加热处理后热固化成型，形成封装体 403。
所述绝缘材料优选为环氧树脂。
在上述方案中，电磁加热模块400在模具500中一体成型，形成封装体403包覆电磁加热线圈401与磁体402的结构，与现有技术相比，省去了电磁加热线圈401与磁体402安装于电磁加热模块400内部的复杂装配工序，很大程度上简化了制造工艺流程。
本实施例中，绝缘材料固化成型后可能存在飞边、凸起等瑕疵，为提高电磁加热模块400的整体美观度，同时也避免所述瑕疵在后期将电磁加热模块400安装至衣物处理装置中时造成影响，可通过打磨修正消除所述瑕疵，使电磁加热模块400的表面更加平滑。
本实施例中，电磁加热模块400的制造工艺具体包括如下步骤：
S101、向模具500内注入绝缘材料；
S102、将磁体402放入模具500中，使绝缘材料没过磁体402的上表面；
S103、将电磁加热线圈401放入模具500中，使绝缘材料没过电磁加热线圈401的上表面；
S104、进行加热处理，使绝缘材料固化成型形成封装体403；
S105、脱模，得到电磁加热模块400。
在上述方案中，向模具500中注入绝缘材料后依次放入磁体402和电磁加热线圈401。磁体402沿模具500中成型腔的径向码放，沿周向放置多个，放置时保证磁体402与模具500的底面之间留有一定距离，保证绝缘材料固化成型后磁体402被完全包覆。电磁加热线圈401放置于磁体402上方，使电磁加热线圈401所在平面与模具500底面平行，同时保证电磁加热线圈401完全浸入绝缘材料中，而不与下方的磁体402接触，以确保电磁加热线圈401与磁体402之间被绝缘材料隔开一定间隔，同时电磁加热线圈401被固化成型后形成的封装体403完全包覆。
本实施例中，形成封装体403的绝缘材料一次性注入模具500中，通过一次加热固化成型即得到电磁加热模块400，制造工艺简单，工艺流程短，易于实现。
实施例九
如图6至图9所示，本实施例与上述实施例八的区别在于：所述的制造工艺具体包括如下步骤：
S201、向模具500内第一次注入绝缘材料，使绝缘材料的深度至少高于磁体402的厚度；
S202、将磁体402放入模具500中，使绝缘材料没过磁体402的上表面；
S203、将电磁加热线圈401放入模具500中；
S204、向模具500内第二次注入绝缘材料，使绝缘材料至少没过电磁加热线圈401的上表面；
S205、进行加热处理，使绝缘材料固化成型形成封装体403；
S206、脱模，得到电磁加热模块400。
在上述方案中，绝缘材料分两次注入模具500中，第一次注入绝缘材料后先放入磁体402，使磁体402完全浸入绝缘材料中。然后再放入电磁加热线圈401，此时电磁加热线圈401可直接放置于绝缘材料的表面，而不用浸没至绝缘材料的液面以下，再通过第二次注入绝缘材料将电磁加热线圈401完全覆盖。
通过上述方式有效地保证了电磁加热线圈401与磁体402之间的间隔距离，避免了采用 上述实施例八的制造工艺，在放入电磁加热线圈401时对磁体402的位置把握不准确，导致两者在成型后的电磁加热模块400中距离过近甚至接触的问题。
本实施例的优选方案中，步骤S202与S203之间还包括步骤S200：进行加热处理，使已注入模具500内的绝缘材料固化成型。
在上述方案中，电磁加热线圈401放入模具500之前先对模具500中的绝缘材料进行加热处理，使其固化成型，再放入电磁加热线圈401时，电磁加热线圈401可以稳定放置于已固化的绝缘材料表面，而不会出现电磁加热线圈401在液态的绝缘材料中下沉，使得最终成型后的电磁加热模块400中，电磁加热线圈401的位置低于预期位置的情况。
本实施例中，绝缘材料分两次注入模具500中，更有利于电磁加热线圈401放置于模具500内合适的高度位置。在放入电磁加热线圈401之间先对模具500内绝缘材料进行加热处理，使其固化成型，电磁加热线圈401放入模具500后不会出现在绝缘材料中下沉的现象，对电磁加热线圈401的位置控制可以更加准确。
实施例十
如图6至图9所示，本实施例与上述实施例八的区别在于：所述的制造工艺具体包括如下步骤：
S301、向模具500内第一次注入绝缘材料，使绝缘材料至少铺满模具500的底面；
S302、将磁体402放入模具500中；
S303、向模具500内第二次注入绝缘材料，使绝缘材料至少没过磁体402的上表面；
S304、将电磁加热线圈401放入模具500中；
S305、向模具500内第三次注入绝缘材料，使绝缘材料至少没过电磁加热线圈401的上表面；
S306、进行加热处理，使绝缘材料固化成型形成封装体403；
S307、脱模，得到电磁加热模块400。
在上述方案中，绝缘材料分三次注入模具500中，三次注入绝缘材料时分别没过模具500底面，磁体402上表面，以及电磁加热线圈401上表面。磁体402和电磁加热线圈401在放入模具500中时，均可以直接放置在当前模具500中已有绝缘材料的表面，而不需要下压以使其浸入绝缘材料中。
通过上述方式可以对磁体402和电磁加热线圈401的放置位置均进行较为准确的控制，避免了磁体402过于接近模具500底面导致未被完全包覆，或者电磁加热线圈401与磁体402之间过于接近甚至产生接触的情况。
本实施例的优选方案中，步骤S301与S302之间，和/或步骤S303和S304之间还包括步骤S300：进行加热处理，使已注入模具500内的绝缘材料固化成型。
最优地，在步骤S301与S302之间，以及步骤S303和S304之间均执行步骤S300。
在上述方案中，磁体402及电磁加热线圈401放入模具500之前先对模具500中的绝缘材料进行加热处理，使其固化成型，然后再放入磁体402或电磁加热线圈401。如此可以将磁体402和电磁加热线圈401稳定放置于已固化的绝缘材料表面，而不会出现磁体402或电磁加热线圈401在液态的绝缘材料中下沉，使得最终成型后的电磁加热模块400中，两者的高度位置与预期的高度位置不符的情况。
本实施例中，绝缘材料分三次注入模具500中，更有利于磁体402及电磁加热线圈401 放置于模具500内合适的高度位置。在放入磁体402或电磁加热线圈401之间均先对模具500内绝缘材料进行加热处理，使其固化成型，磁体402和电磁加热线圈401放入模具500后不会出现在绝缘材料中下沉的现象，对磁体402及电磁加热线圈401的位置控制更加准确。
实施例十一
如图10所示，本实施例提供一种衣物处理装置，包括上述实施例七所述的电磁加热模块400。
具体地，本实施例以洗衣机为例进行说明。所述的洗衣机包括外筒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，本实施例洗衣机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及排水结构排出洗衣机。
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6至图8和图10所示，洗衣机启动加热程序后，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中的电磁加热线圈401后，电磁加热线圈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10所示为本实施例洗衣机的仰视图，其中外壳100的底部区域被取下，以展示洗衣机的内部结构。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6至图8和图10所示，本实施例中，电磁加热模块400安装时，电磁加热线圈401 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，电磁加热线圈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。电磁加热线圈401下方的磁体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，使得电磁加热线圈401产生的磁场更加高效地作用在内筒上，提高了加热效率。
电磁加热线圈401和磁体402嵌入设置在封装体403内部，使电磁加热线圈401和磁体402均被封装体403完全包覆，表面无缝隙。电磁加热线圈401上不存在任何暴露于电磁加热模块400外部的部分，即使外筒200出现渗水滴落至电磁加热模块400表面，也不会与包覆于封装体403内部的电磁加热线圈401接触，避免了电磁加热线圈401接触洗涤水造成短路故障的情况，具有可靠的防水效果。
本实施例的洗衣机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之间无水的洗衣机的洗涤水加热目的。电磁加热模块400设置在外筒200下方，洗衣机工作期间不与洗涤水接触，并通过封装体403完全包覆电磁加热线圈401，完全避免了电磁加热线圈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。
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。
