本申请主要提出一种线圈盘，主要应用于烹饪炊具中，以增加线圈安装的稳定性和可靠性，同时，避免在线圈的固定过程中使用胶水，避免在线圈盘的使用过程中产生异味。同时，通过设置不同形状的夹线筋形状，使得线圈盘可以适用于不同的工作平台，以对不同的锅具进行加热。通过对夹线间隙中的结构进行改进，使得位于夹线间隙中的线圈绕组800的排列形状、尺寸、相对位置关系等得到想要的改变，以使线圈盘的加热更加均匀。
以下将主要描述线圈盘的具体结构。

具体地，本实施例中，支撑结构300的形状可以有很多，以呈柱状设置为例，支撑结构300的横截面可以为三角形、圆形、椭圆形、方形等等，以呈圆形为例。支撑结构位于线圈盘的中部，则可以理解为将支撑结构设置在线圈盘整体的中部区域，不受线圈盘的具体形状和组成(既可以为整体的线圈盘，也可以为由多个子线圈盘组合而成的线圈盘)的限制。第一夹线筋100和第二夹线筋200设置在支撑结构300的侧壁上。第一夹线筋100和第二夹线筋200和支撑结构300的连接方式可以有很多，可以通过，如通过螺钉连接、卡扣连接、胶粘等，当然，在一些实施例中，也可以将第一夹线筋100和第二夹线筋200与支撑结构300一体成型设置。
第一夹线筋100和第二夹线筋200的形状和结构可以相同，也可以不同，只要在第一夹线筋100和第二夹线筋200之间能形成第一夹线间隙400即可。下面以介绍第一夹线筋100为例，第二夹线筋200有第一夹线筋100配合，以围合形成所需要的第一夹线间隙400。
第一夹线筋100的形状可以有很多，可以根据不同形状的锅具来设置不同的形状，从而使得第一夹线间隙400中的线圈绕组800与锅具的形状适配；第一夹线筋100的形状还可以根据不同的工况需求来设置，本实施例中，以呈长条形设置为例。第一夹线筋100的一端与支撑结构300固定连接，另一端向远离支撑结构300的方向延伸，可以沿垂直于支撑结构300的长度方向延伸，也可以倾斜向上或者倾斜向下延伸，具体的延伸方式根据具体的工况或者实际需求确定。第一夹线筋100和和第二夹线筋200由绝缘的硬质材料制成，与硬质塑料。
为了提高绕线效果，所述第一夹线筋100的数量为多个，多个所述第一夹线筋100沿所述支撑结构300的周向呈辐射状排布；和/或，所述第二夹线筋200的数量为多个，多个所述第二夹线筋200沿所述支撑结构300的周向呈辐射状排布，以使夹线间隙沿所述支撑结构300的周向排布。即多个第一夹线筋100的一端均与支撑结构300连接，另一端以支撑结构300为中心，向四周辐射排列；同理，多个第二夹线筋200的一端均与支撑结构300连接，另一端以支撑结构300为中心，向四周辐射排列。如此，使得第一夹线间隙400沿支撑结构300的周向排布。使得漆包线绕制到第一夹线间隙400中时，可以多个位置被夹持，从而提高漆包线被夹持的稳定性。
关于第一夹线筋100和第二夹线筋200的相对位置关系，第二夹线筋200位于第一夹线筋100的下方可以包括多种情形，可以根据不同的需求设置不同的情形：第一种情形，第二夹线筋200位于第一夹线筋100的正下方，此时的第一夹线间隙400的截面呈倒U形设置；第二种情形，第二夹线筋200的部分位于第一夹线筋100的正下方，部分位于相邻两第一夹线筋100之间的间隙正下方；第三种情形，第二夹线筋200完全位于相邻两第一夹线筋100之间的间隙正下方，此时，第一夹线筋100和第二夹线筋200在水平面内的投影不相交。下面以第三种情形为例进行具体的说明：
相邻的两所述第一夹线筋100之间具有第一间隙110，相邻的第二夹线筋200之间具有第二间隙210，所述第二夹线筋200对应所述第一间隙110位于相邻的两所述第一夹线筋100之间，第一夹线筋100对应第二间隙210位于相邻的两第二夹线筋200之间。当第一夹线筋100、第二夹线筋200和支撑结构300一体注塑成型时，有利于脱模，并且，如此设置，使得线圈绕组800的两侧间隔被支撑(第一夹线筋100和第二夹线筋200交替支撑)，从而使得线圈绕组800更加稳定地被夹持。
关于第一夹线间隙400中漆包线的层数，可以根据需求来设置，具体地，绕制于所述夹线间隙中的线圈绕组800的层数为2～5层。层数太少，不利于提高线圈盘的工作效 率，层数太多，不利于线圈绕组800的绕制的稳定性。关于第一夹线筋100和第二夹线筋200之间的距离，即夹线间隙的高度H为2～20mm。夹线间隙太小，不利于漆包线的进入和绕制，间隙太大，不利于绕制后漆包线的稳定性。
本实施例中，通过在第一夹线筋100和第二夹线筋200的设置，以在第一夹线筋100和第二夹线筋200之间形成第一夹线间隙400，漆包线绕制在绕线间隙中，使得线圈被第一夹线筋100和第二夹线筋200夹持，从而实现对线圈的固定，相较于现有的固定方式，线圈的固定不需要使用胶水，从而在线圈发热时也不会产生异味，有利于用户的使用；另外，通过该种方式绕制和固定线圈的效率大幅增加，绕制后的线圈稳定性的得到大幅增加；值得说明的是，由于第一夹线筋100和第二夹线筋200均具有自由端，使得第一夹线筋100和第二夹线筋200的活动更加灵活，当向第一夹持间隙中绕制线圈时，有利于线圈的进入和夹持，特别是在设置多层线圈时，有利于线圈在第一夹持间隙中的排布。
值得说明的是，在一些实施例中，多个第二夹线筋200与支撑结构300连接后组合形成线圈支架500，以供线圈绕组800安装。在一些实施例中，为了提高线圈支架500的稳定性，相邻的第二夹线筋200之间相互连接，连接的位置可以有很多，以远离支撑结构300的一端为例。
在一些实施例中，为了提高漆包线被夹持的稳定性，所述第一夹线筋100的宽度自所述支撑结构300向外逐渐增加；和/或，所述第二夹线筋200的宽度自所述支撑结构300向外逐渐增加。本实施例中，既可以是第一夹线筋100的宽度得到增加，也可以是第二夹线筋200的宽度得到增加，还可以是第一夹线筋100和第二夹线筋200的宽度同时增加。第一夹线筋100和第二夹线筋200呈片状设置，并且，随着第一夹线筋100和第二夹线筋200距离支撑结构300的距离越远，第一夹线筋100和第二夹线筋200的宽度越大，如此，使得第一夹线筋100和第二夹线筋200夹持线圈绕组800的面积，随着线圈绕组800直径的增加而逐渐增加。如此，有利于增加第一夹线间隙400夹持线圈绕组800的稳定性。
为了提高线圈盘工作的稳定性，降低线圈盘工作时的温度所述第一夹线筋100上开设有第一散热口；和/或，所述第二夹线筋200上开设有第二散热口。第一散热口沿第一夹线筋100的长度方向开设，第二散热口沿第二夹线筋200的长度方向开设。第一散热口和第二散热口的形状可以有很多，如长条形，圆形、多边形等均可。通过第一散热口和第二散热快的设置，使得线圈盘在工作时，热量可以及时的散出，从而避免线圈温度过高而影响线圈盘工作。
在一些实施例中，为了提高结构的紧凑性，所述第二夹线筋200背对所述第一夹线筋100的一侧开设有安装槽，以供磁条600安装。值得说明的是，安装槽的槽宽和/或槽深，沿第一夹线间隙400的延伸方向(自支撑结构300开设)逐渐增加，以使得安装槽可以安装逐渐变宽或者逐渐变厚的磁条600，以在线圈盘的周边部分产生更强的磁场。如此，磁条600可以便捷的安装在线圈盘上，并且与线圈的绕制相适配(通过逐渐增加磁条600的宽度，以减小相邻两磁条600之间的间隙随着线圈盘直径的增加而增加的趋势)，以使线圈盘的加热更加均匀。
第一夹线间隙400可以有不同的形状，以适应不同的公开需求，下面举几个例子进行说明，所述第一夹线筋100和所第二夹线筋200具有平直段，以使所述第一夹线间隙400的径向截面具有平直段；和/或，所述第一夹线筋100和所第二夹线筋200具有阶梯段，以使所述第一夹线间隙400的径向截面具有阶梯段；和/或，所述第一夹线筋100和所第二夹线筋200具有弧形弯曲段，以使所述第一夹线间隙400的径向截面具有弧形弯曲段。
本实施例中，第一夹线间隙400可以全部为平直段，也可以部分为平直段；可以全部为阶梯段，也可以部分为阶梯段；可以全部为弧形弯曲段，也可以部分为弧形弯曲段。 当第一夹线筋100和第二夹线筋200均为平直的夹线筋时，第一夹线间隙400为平直的夹线间隙，当线圈绕制到第一夹线间隙400中时，线圈排列呈平直(线圈层数相同)的圆环。
当第一夹线筋100和/或第二夹线筋200为具有阶梯的板时，第一夹线间隙400为具有阶梯的间隙，此时线圈的层数不同，线圈层数多的位置可以有很多，圆环内侧、中部和外侧均可。以多层设置在外侧为例，如此设置使得线圈盘外侧的线圈较多，如此，可以补偿由于线圈盘外侧平均磁场较弱(随着线圈盘直径的增加，相邻磁条600之间的间隙也逐渐增加，导致磁条600之间的线圈所在的区域，磁场强度逐渐变弱)而导致的加热效率不高，使得线圈盘的内侧和外侧在工作过程中，加热均匀。
使得第一夹线间隙400呈弧形弯曲的第一夹线筋100和第二夹线筋200的形式可以有很多，如第一夹线筋100呈弧形设置(线圈沿第一夹线筋100的长度方向排列)，或者第二夹线筋200呈弧形设置(线圈沿第二夹线筋200的长度方向排列)，或者第一夹线筋100和第二夹线筋200均呈弧形设置(线圈沿第一夹线筋100或者第二夹线筋200的长度方向排列)。以第一夹线筋100和第二夹线筋200均呈弧形设置为例，并且，第一夹线筋100和第二夹线筋200的曲线相当，使得第一夹线间隙400的弯曲延伸方向与第一夹线筋100和第二夹线筋200的延伸方向相同，并且，第一夹线间隙400均匀设置(即整个第一夹线间隙400的宽度相当)，有利于对漆包线的均匀夹持，从而有利于线圈盘的均匀工作。
在一些实施例中，参见图14～16，为了进一步提高线圈盘加热的效率和均匀性，所述第一夹线间隙400包括内弧段850，所述内弧段850自所述支撑结构300向下弯曲延伸。内弧段850的形式可以有很多，如呈凹弧，或者凸弧，或者为凹弧和凸弧同时存在。通过将第一夹线间隙400设为包括内弧段850，绕制在内弧段850的漆包线密度(单位径向尺寸内漆包线的圈数)增加，如此，有利于增加线圈盘中部的效率。通常情况下，线圈盘中间位置的磁场强度较强，此时通过设置多的线圈，以充分利用较强的磁场强度，从而提高线圈盘的工作效率。内弧段850以设置为凹弧为例，使得绕制在内弧段850的漆包线密度(单位径向尺寸内漆包线的圈数)沿线圈盘的径向方向逐渐减小，即在内弧段850内靠近支撑结构300的线圈密度较强，该排列方式与磁场的强度从中部向四周逐渐减弱的趋势相适配，从而进一步充分合理的利用磁场强度。当线圈盘的外侧设置有多层线圈或者设置有大于内侧的磁场强度时，通过增加线圈盘内侧(内弧段850)的加热效率，有利于提高整个线圈盘的加热均匀性。
为了进一步提高线圈盘的工作效率，通过对第一夹线间隙400的形状进行设置，使得绕制在第一夹线间隙400中的线圈绕组800具有聚磁的功能，以充分的利用磁场来提高线圈盘的工作效率。具体地，所述第一夹线间隙400还包括过渡段860和外弧段870；所述内弧段850自所述支撑结构300向下呈凹弧设置，所述外弧段870自所述过渡段860向上呈凹弧设置，所述内弧段850和所述外弧段870通过过渡段860圆弧过渡连接。其中，过渡段860可以为平直段，也可以为凹弧段。通过内弧段850、外弧段870以及过渡段860的设置，使得第一夹线间隙400从支撑结构300(线圈盘中部)向四周延伸的过程中，先逐渐降低然后逐渐增加，也使得绕制与第一夹线间隙400中的线圈密度先逐渐减小，然后逐渐增加。当磁场经过如此设置的线圈绕组800时，将经过线圈的磁场得到充分利用，从而有效的提高线圈盘的工作效率的工作均匀性。
在一些实施例中，参照图10～12，为了进一步的提高线圈盘工作的均匀性，所述线圈盘还包括线圈支架500，所述线圈支架500位于所述第二夹线筋200的下方，所述第二夹线筋200、线圈支架500以及所述支撑结构300之间围合形成第二夹线间隙430；所述夹线间隙和第二夹线间隙430通过开口450连通，在线圈盘的漆包线的绕制过程中，当漆包线经过开口450时，从夹线间隙进入到第二夹线间隙430，或者从第二间隙210进入到夹线间隙，以使漆包线通过开口450在夹线间隙和第二夹线间隙430之间交替绕 制。
具体地，本实施例中，第二夹线筋200位于相邻的两第一夹线筋100之间的间隙的下方，即第一夹线筋100和第二夹线筋200在上下方向上部分重叠或者不重叠。第二夹线筋200与线圈支架500之间具有间隙，并且，由于第二夹线筋200沿支撑结构300的周向间隔分布，使得第一夹线间隙400与第二夹线间隙430通过相邻的两第二夹线筋200之间的间隙连通，即开口450的个数可以有多个。在线圈绕组800的绕制过程中，可以每个开口450处均切换夹线间隙(第一夹线间隙400和第二夹线间隙430之间的切换)，也可以只在同一个开口450处切换夹线间隙。线圈绕组800可以每绕一圈就切换夹线间隙，也可以在绕制多圈后切换至另一夹线间隙，并且在另一夹线间隙中绕制多圈后切换回原来的夹线间隙继续绕制。
以每经过同一开口450处时切换夹线间隙为例，开口450沿所述线圈盘的径向设置，漆包线每次经过该开口450时都从第一夹线间隙400进入到第二夹线间隙430，或者从第二间隙210进入到第一夹线间隙400，以使第一夹线间隙400和第二夹线间隙430中线圈依次交替绕制。以现在第一夹线间隙400中绕制为例，在经过开口450时，线圈从第一夹线间隙400进入到第二夹线间隙430，在第二夹线间隙430中绕制一圈后，通过同一开口450回到第一夹线间隙400中继续绕制，如此交替往复。通过如此绕制线圈绕组800，使得第一夹线间隙400和第二夹线间隙430中的线圈均匀绕制，从而大幅的提高了线圈盘工作的时的均匀性，同时，如此绕制，避免在绕制完一夹线间隙(以第一夹线间隙400为例)后，必须要设置过渡段860才能进入到另一间隙间隙(以第二夹线间隙430为例)中继续绕制，完全避免了过渡段860的存在，使得双层线圈的绕制更加紧凑、规整，工作均匀性更好。
在一些实施例中，为了进一步去的提高线圈盘工作的工作效率和均匀性，所述线圈盘包括内环加热区和外环加热区；所述第一夹线间隙400包括位于所述内环加热区的内夹线间隙410和位于所述外环加热区的外夹线间隙420，所述内夹线间隙410和所述外夹线间隙420向上倾斜设置且倾斜角度不同。值得说明的是，本实施例中仅以两个加热区为例进行说明，在其他的实施例中，可以包括三个、四个甚至更多的加热区，多个加热区之间的位置关系，可以参照本实施例中内环加热区和外环加热区进行合理的推理。应当理解的是，多个加热区的技术方案以本实施例中的两个加热区为基础，应当属于本申请的保护范围。
具体地，本实施例中，线圈盘至少包括两个加热区，一个是位于线圈盘中央的内环加热区，内环加热区可以呈圆形设置，也可以呈圆环形设置；另一个为环设于内环加热区周围的外环加热区，外环加热区呈圆环形设置。内环加热区和外环加热区分别由不同的线圈绕组800进行加热，从而分别设置有内夹线间隙410和外夹线间隙420。
值得说明的是，内夹线间隙410和外夹线间隙420向上倾斜设置的起点为支撑结构300，即从支撑结构300向远离支撑结构300的上方倾斜。倾斜的方式有多种，可以为呈直线倾斜，也可以为呈弧形倾斜，以呈凹弧倾斜为例。通过将内环间隙和外环间隙设置为倾斜角度不同(呈直线倾斜时斜率不同，呈弧形倾斜时曲率不同)，使得线圈盘的线圈与被加热锅具之间的距离具有多样性，从而使得线圈盘的加热具有更高的适应能力(可以适应于多种不同的工况)和更好的均匀性。
在一些实施例中，为了进一步的提高线圈盘工作的适应性和均匀性，所述外夹线间隙420包括呈上下排布的第一绕线间隙421和第二绕线间隙422，所述第一绕线间隙421和第二绕线间隙422的倾斜角度不同。本实施例中，在外环加热区的第一绕线间隙421和第二绕线间隙422层叠设置，并且二者的倾斜角度不同，进一步的丰富了线圈绕组800与锅具之间的距离，提高了适应性和均匀性。
关于倾斜角度的不同，当倾斜的方式为弧形倾斜时，体现为弧形倾斜曲率不同，参照图7～9，图中体现有内夹线间隙410、第一绕线间隙421和第二绕线间隙422所在直 线的延长线，各延长线的曲率R1、R2、R3均不同。
值得说明的是，在线圈盘的使用过程中，第一绕线间隙421和第二绕线间隙422中的线圈绕组800可以串联、并联，也可以相互独立工作。可以根据具体的工况需求，选择性的使用第一绕线间隙421中的线圈绕组800、第二绕线间隙422中的线圈绕组800，串联或者并联的同时使用第一绕线间隙421和第二绕线间隙422中的线圈绕组800。
下面提供一种实现上面实施例的具体结构方案：
所述支撑结构300包括位于所述内环加热区的内支撑结构310和位于所述外环加热区的外支撑结构320；
所述第一夹线筋100包括第一内夹线筋121和第一外夹线筋122，所述第二夹线筋200包括第二内夹线筋221和第二外夹线筋222；
所述第一内夹线筋121和第二内夹线筋221自内支撑结构310朝外环加热区的方向、向上倾斜设置，以在所述第一内夹线筋121和第二内夹线筋221之间形成内夹线间隙410；
所述第一外夹线筋122和第二外夹线筋222自外支撑结构320朝远离内环加热区的方向、向上倾斜设置，以在所述第一外夹线筋122和第二外夹线之间形成外夹线间隙420。值得说明的是，在其他实施例中，支撑结构的数量可以根据加热区的分区情况进行调整，本实施例中，仅以基础的内、外支撑结构进行说明。应当理解的是，多个支撑结构的技术方案以本实施例中的内、外两个支撑结构为基础，应当属于本申请的保护范围。
其中，内支撑结构310呈柱状设置于线圈盘的中央，外支撑结构320环设在内支撑结构310的外侧，内支撑机构和外支撑结构320之间具有间隙。第一内夹线筋121和第二内夹线筋221从内支撑结构310向外支撑结构320延伸，第一内夹线筋121位于第二内夹线筋221的上方(在上方的形式有多种，包括正对、完全错开和部分错开几种情形，具体地请参见上面的实施例)。第一内夹线筋121和第二内夹线筋221可以呈直线形，也可以呈长条弧形，保证第一内夹线间隙410向上倾斜即可。
同理，第一外夹线筋122和第二外夹线筋222从外支撑结构320向远离内支撑结构310的方向延伸，第一外夹线筋122位于第二外夹线筋222的上方(在上方的形式有多种，包括正对、完全错开和部分错开几种情形，具体地请参见上面的实施例)。第一外夹线筋122和第二外夹线筋222可以呈直线形，也可以呈长条弧形，保证第一外夹线间隙420向上倾斜即可。外支撑结构320呈圆环形设置，多个第一外夹线筋122和第二外夹线筋222沿外支撑结构320的周向排布。
在一些实施例中，参见图17～图20，为了进一步的提高线圈盘的适应性，提高线圈盘对能量的利用率，所述线圈盘包括内环加热区和外环加热区；所述夹线间隙包括位于所述内环加热区的内夹线间隙410和位于所述外环加热区的外夹线间隙420；所述外夹线间隙420包括呈上下排布的第一绕线间隙421和第二绕线间隙422，和/或，所述内夹线间隙410包括呈上下排布的第三绕线间隙411和第四绕线间隙412；所述第一绕线间隙421和第二绕线间隙422分别设置有第一线圈绕组810和第二线圈绕组820；和/或，所述第三绕线间隙411和第四绕线间隙412分别设置有第三线圈绕组830和第四线圈绕组840。
具体地，本实施例中，线圈盘的内环加热区可以为单层，也可以设置为多层，以两层为例，分别设置有第三绕线间隙411和第四绕线间隙412，对应的第三绕线间隙411中绕制有第三线圈绕组830，第四绕线间隙412中绕制有第四线圈绕组840。同理，线圈盘的外环加热区可以为单层，也可以设置为多层，以两层为例，分别设置有第一绕线间隙421和第二绕线间隙422，对应的第一绕线间隙421中绕制有第一线圈绕组810，第二绕线间隙422中绕制有第二线圈绕组820。
其中，关于线圈绕组800之间的关系：
所述第一线圈绕组810与所述第二线圈绕组820相互独立；或者，所述第一线圈绕组810与所述第二线圈绕组820串联；或者，所述第一线圈绕组810与所述第二线圈绕 组820并联。所述第三线圈绕组830与所述第四线圈绕组840相互独立；或者，所述第三线圈绕组830与所述第四线圈绕组840串联；或者，所述第三线圈绕组830与所述第四线圈绕组840并联。当然，在一些实施例中，根据特殊的需求，可以实现第一线圈绕组810和第三线圈绕组830(或者第四线圈绕组840)的串联或者并联，也可以实现第二线圈绕组820和第三线圈绕组830(或者第四线圈绕组840)的串联或者并联。
由于不同层的线圈绕组800距离被加热锅具之间的距离不同，使得不同位置的线圈适应于不同的锅具加热需求。具体地，为了不同的工况需求，可选择的使用内环加热区、外环加热区，内环加热区和外环加热区同时使用。下面从加热的位置和线圈盘大、小功率的角度来具体说明：
当仅中部需要加热时，选择第三线圈绕组830、第四线圈绕组840，或者串联或者并列的同时使用第三线圈绕组830和第四线圈绕组840；使用第三线圈绕组830时功率较大，使用第四线圈绕组840时功率较小，第三线圈绕组830和第四线圈绕组840并联使用时的功率大于单独使用第三线圈绕组830时的功率；
当仅周边需要加热时，选择第一线圈绕组810、第二线圈绕组820，或者串联或者并列的同时使用第一线圈绕组810和第二线圈绕组820；使用第一线圈绕组810时功率较大，使用第二线圈绕组820时功率较小，第一线圈绕组810和第二线圈绕组820并联使用时的功率大于单独使用第一线圈绕组810时的功率。
当中部和周边都需要加热时，在内环加热区和外环加热区各选一组线圈绕组800搭配进行工作，如选择第三线圈绕组830，以及并联使用第一线圈绕组810和第二线圈绕组820。
其中，为了提高线圈绕组800工作的智能化和便捷性控制，所述线圈盘包括控制电路板，所述控制电路板上设置第一切换电路，所述第一切换电路分别与所述第一线圈绕组810和第二线圈绕组820连接，以切换所述第一线圈绕组810和第二线圈绕组820的连接关系；和/或，所述控制电路板上设置第二切换电路，所述第二切换电路分别与所述第三线圈绕组830和第四线圈绕组840连接，以切换所述第三线圈绕组830和第四线圈绕组840的连接关系。本实施例中，通过设置第一切换电路，根据需求控制第一线圈绕组810工作，或者第二线圈绕组820工作，或者第一线圈绕组810和第二线圈绕组820串联或者并联工作。同理，通过设置第二切换电路，根据需求控制第三线圈绕组830工作，或者第四线圈绕组840工作，或者第三线圈绕组830和第四线圈绕组840串联或者并联工作。当然，在一些实施例中，第一切换电路和第二切换电路由控制电路板上的主控电路控制，主控电路可以根据指令或者需求协调第一切换电路和第二切换电路的工作，以使线圈盘的工作按照需求进行工作。
在一些实施例中，为了进一步的提高线圈盘对能量的利用率，和延长控制电路板上IGBT(Insulated Gate Bipolar Transistor，绝缘栅双极型晶体管)的使用寿命，所述线圈盘还包括：
与所述第一线圈绕组810配置的第一电感L1和第一电阻R1；
与所述第二线圈绕组820配置的第二电感L2和第二电阻R2；
与所述第三线圈绕组830配置的第三电感L3和第三电阻R3；
与所述第四线圈绕组840配置的第四电感L4和第四电阻R4；
所述第一电感L1小于所述第二电感L2和/或第四电感L4；
所述第一电阻R1大于所述第二电阻R2和/或第四电阻R4；
所述第三电感L3小于所述第四电感L4和/或第二电感L2；
所述第三电阻R3大于所述第四电阻R4和/或第二电阻R2。
具体地，本实施例中，第一线圈绕组810位于第二线圈绕组820的上方，第三线圈绕组830位于第四线圈绕组840的上方，使得第一线圈绕组810和第三线圈绕组830适合较高功率的工作，第二线圈绕组820和第四线圈绕组840适合较低功率的工作。此时， 需要为第一线圈绕组810配置较小的第一电感L1，较大的第一电阻R1，为第二线圈绕组820配置较小的第二电感L2和较小第二电阻R2，即L1<L2，R1>R2；同理，需要为第三线圈绕组830配置较小的第三电感L1，较大的第三电阻R1，为第四线圈绕组840配置较小的第四电感L4和较小第四电阻R4，即L3<L4，R3>R4。如此设置，使得不同的工作需要可以选择不同的线圈绕组800，并且为不同的线圈绕组800配置有与之适应的电感和电阻，以使得对应的线圈绕组800可以适配工作需求。如此，在充分合理的利用电能的同时，也避免控制电路板上的IGBT产生较高的温度，从而使得IGBT的工作温度，同时有利于延长IGBT的使用寿命。其中，配置电感的方式可以通过设置线圈绕组800的匝数来实现，线圈匝数越多电感越大，线圈匝数越少电感越小。因此，可以将第一线圈绕组810的匝数设置为少于第二线圈绕组820的匝数，第三线圈绕组830的匝数设置为少于第四线圈绕组840的匝数。
为了进一步的达到内环加热区和外环加热区的线圈绕组800协调工作的目的，可以对电感和电阻进一步进行限定，L1<L4，R1>R4；L3<L2，R3>R2，如此，使得第一线圈绕组810(外环加热区)可以与第四线圈绕组840(内环加热区)匹配使用，使得第三线圈绕组830(内环加热区)可以与第二线圈绕组820(外环加热区)匹配使用。如此，使得线圈上的线圈绕组800可以任意配置使用，均能满足线圈满节能和延长IGBT使用寿命的需求。
值得说明的是，上述仅以内环加热区和外环加热区各两组线圈绕组800进行距离说明，可以理解的是，可以将上述方案推广到每个加热区设置多组线圈绕组800，也可以推广到设置更多的加热区域。凡属于上述推广的，均属于本申请的发明构思。
在一些实施例中，参照图13，为了使得线圈盘适用于现有的工作平台，不增加线圈盘总高度的情况下设置不同情形的线圈绕组800，位于所述内夹线间隙410内的线圈绕组800的高度h1，和位于外夹线间隙420内的线圈绕组800的高度h2相当。当外环加热区设置两层线圈绕组800时，两层线圈绕组800(上下重叠)的高度，与单层的内环加热区的线圈绕组800的高度相当。反之，当内环加热区设置两层线圈绕组800时，两层线圈绕组800(上下重叠)的高度，与单层的外环加热区的线圈绕组800的高度相当。由于线圈绕组800倾斜设置，可以通过调节线圈绕组800的倾斜角度来实现单层的高度与双层相当。本实施例中，通过将内夹线间隙410中的线圈绕组800的高度h1设置为与外夹线间隙420中的线圈绕组800的高度h2相当，使得线圈盘充分合理的利用空间，避免额外增加线圈盘的高度，从而使得线圈盘可以应用于现有的工作平台上，大幅的降低了烹饪炊具的制造成本。
参见图19，本申请还提出一种烹饪炊具，该烹饪炊具包括底座700和线圈盘，该线圈盘的具体结构参照上述实施例，由于本烹饪炊具采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，线圈盘安装于底座700上。
参照图20至图25，在本申请实施例中，该线圈盘还包括：
线圈支架100，所述线圈支架100具有位于线圈支架100中部的内加热区200和位于线圈支架100周缘外加热区300；
内部磁条500，所述内部磁条500对应所述内加热区200设置；
外部磁条400，所述外部磁条400对应所述外加热区300设置；
所述外部磁条400覆盖外加热区300的面积大于所述内部磁条500覆盖内加热区200的面积。
具体地，本实施例中，线圈支架100的整体外形可以有很多，如三角形、四边形等多边形，椭圆形、圆形等均可，本实施例中，以整体呈圆形设置为例。内加热区200的形状可以有很多，如三角形、四边形、圆形、圆环形等均可，以呈圆形设置为例。外加热区300呈环形设置，套设在内加热区200的外侧。内加热区200主要影响线圈盘中部 的加热效率，外加热区300主要影响线圈盘周边区域的加热效率。
内部磁条500的形状可以有很多，如长条形、圆形、扇形等均可。内部磁条500的数量为多个，多个内部磁条500的一端向内加热区200的中部延伸，另一端向内换热加热区的四周辐射排布。同理，外部磁条400的形状也可以有很多，如长条形、圆形、扇形等均可。外部磁条400的数量为多个，多个外部磁条400的一端向外加热区300与内加热区200的交界处延伸，另一端向外换热加热区的四周辐射排布。
实现外部磁条400覆盖外加热区300的面积大于内部磁条500覆盖内加热区200的面积的方式有多种。在单个外部磁条400的覆盖面积与单个内部磁条500的覆盖面积相当时，增加外部磁条400的数量，增加外部磁条400在外加热区300的排布密度，从而达到增加总的覆盖面积的目的。在外部磁条400的数量与内部磁条500的数量相当时，增加单个外部磁条400的面积，以增加外部磁条400覆盖的总面积。从而达到增强外加热区300的磁场强度的目的。其中，当所述外部磁条400的数量大于所述内部磁条500的数量时，所述外部磁条400与所述内部磁条500相互独立设置，如此，只需要调整磁条的数量，就可以简单的实现增加磁场强度的目的。
值得说明的是，在一些实施例中，内部磁条500和外部磁条400可以一体成型设置，此时，磁条的宽度沿内加热区200到外加热区300的方向逐渐增加，以使单个磁条的磁场长度沿磁条的长度方向逐渐增强。
另外，关于线圈盘上加热区的数量，加热区的数量可以有很多，可以不仅仅包括内加热区200和外加热区300，如三个、四个等等，本实施例中，仅以包括基础的两个加热区为例进行说明。
本实施例中，通过将外部磁条400覆盖外加热区300的面积，设置为大于内部磁条500覆盖内加热区200的面积，使得通过外加热区300的外线圈绕组330的磁场强度得到增加，大幅的减小了外线圈绕组330和内线圈绕组220所在位置的磁场强度差，以使得线圈盘中部和四周的磁场强度相当，从而使得线圈盘对锅具中部和四周的加热效率相当，使得锅具可以得到均匀的加热；同时，通过增加外环线圈的磁场强度，使得外环线圈的利用率得到大幅的增加，有利于提高线圈盘的工作效率。
参照图25至图24，下面分别解释设置于内加热区200和外加热区300的线圈绕组和磁条的结构以及位置关系；
为了进一步提高内加热区200的加热效率，在所述内加热区200绕制有内线圈绕组220，所述内线圈绕组220具有位于内加热区200中部的内平面加热绕组221，和位于边缘且向上倾斜设置内斜面加热绕组222；内部磁条500包括对应所述内平面加热绕组221设置的内平面段510，和对应内斜面加热绕组222设置的内倾斜段520。
具体地，本实施例中，内线圈绕组220的中部呈水平设置，四周的部分自水平的部分向上倾斜延伸。即内线圈绕组220中部的部分排列呈平面(内平面加热绕组221)，内线圈绕组220边缘的部分自平面部分向上排列呈倾斜面(内斜面加热绕组222)。其中，倾斜指的延伸趋势，因此具体的实现方式有很多，如平面倾斜、弧面倾斜、波浪面倾斜等均可。在内线圈绕组220的径向方向上，倾斜部分的线圈密度大于平面部分的线圈密度。通过将内部磁条500设置于内斜面加热绕组222对应的内倾斜段520，使得内倾斜段520补偿内斜面加热绕组222的磁场强度，以使内斜面加热绕组222和内平面加热绕组221所在区域的磁场强度相当，从而有利于均匀加热。另外，通过内斜面加热绕组222的设置，在增加内加热区200边缘加热效率的同时，使得内斜面加热绕组222距离锅具更近，有利于对锅具的加热。
另外，为了提高线圈盘内加热区200的加热均匀性，所述内部磁条500的宽度沿所述内加热区200的中部至边缘的方向逐渐增加。随着内部磁条500宽度的增加，使得磁场强度也随着磁条的延伸方向增加，如此，刚好对面积逐渐增加的内线圈绕组220进行补偿，大幅的减小了相邻两内部磁条500之间的距离差，使得内加热区200的中部和周 边的加热效率相当。
在一些实施例中，为了进一步提高线圈盘中部的加热效率，所述内斜面加热绕组222呈弧形设置，所述内倾斜段520对应所述内斜面加热绕组222呈弧形设置，以使所述内倾斜段520与所述内斜面加热绕组222之间的距离，与内平面段510至内平面加热绕组221之间的距离相当。
本实施例中，将内斜面加热绕组222设置呈凹弧形在不影响内平面加热绕组221工作的情况下，在有限的高度内增加了线圈绕组的数量，从而在有限的高度空间内增加了内斜面加热绕组222的工作效率。通过将内倾斜段520沿内斜面加热绕组222弧形延伸，使得内倾斜段520不仅仅为内斜面加热绕组222提供足够的磁场强度，也保持有相当于内平面段510至内平面加热绕组221之间的距离，使得内斜面加热绕组222和内平面加热绕组221的加热效果相当，有利于均匀加热。
在另一些实施例中，为了提高内加热区200中间位置的加热效率，所述内部磁条500还包括凸出段530，所述凸出段530与所述内平面段510远离所述内倾斜段520的一端连接，所述凸出段530与所述内平面段510垂直。凸出段530沿线圈盘的高度方向设置，集中设置内加热区200中间的位置，如此，大幅的增加了内加热区200中部的磁场强度，从而有利益大幅提高内加热区200中部的加热效率。有利于在有限的空间内提高加热效率，充分合理的利用了空间，提高了结构的紧凑性。
值得说明的是，内支撑结构230的形状可以有很多，以整体外形呈柱状为例。在一些实施例中，为了提高凸出段530的安装稳定性，同时合理的利用空间，在内支撑结构230的底部开设有安装孔231，以供内部磁条500的凸出段530安装。凸出段530从安装孔231竖直向上延伸***到内支撑结构230内，安装孔231沿内支撑结构230的高度方向贯穿。
为了提高内线圈绕组220的安装稳定性和便捷性，所述内加热区200域的中间设置有内支撑结构230，内支撑结构230上设置有第一内夹线筋210；第一内夹线筋210与线圈支架100之间形成第一内绕线间隙240，所述内线圈绕组220设置于所述第一内绕线间隙240内。其中，第一内夹线筋210的形状可以有很多，以具有平直段和弧形段为例，使得第一内绕线间隙240也可以具有平直段与弧形段，从而与内线圈绕组220的内平面加热绕组221和内斜面加热绕组222对应。
第一内夹线筋210的一端与内支撑结构230固定连接，另一端自内支撑结构230向内加热区200的边缘延伸，使得第一内夹线筋210、内支撑结构230和线圈支架100围合形成第一内绕线间隙240。多个第一内夹线筋210沿支撑结构排列成环形，使得第一内绕间隙排列成环形，如此，有利于内线圈绕组220的绕制。使得内线圈绕组220的形状可以通过调整第一内夹线筋210的排列来实现。内线圈绕组220在绕制过程中，只需要将漆包线夹持与第一内绕线间隙240中即可。使得漆包线可以简单、可靠的绕制在第一内绕线间隙240内。在第一内绕线间隙240中的绕组以密绕为例。
为了提高内加热区200的加热效率，充分合理的利用空间，缩小线圈盘的面积，所述线圈盘还包括第二内夹线筋，所述第二内夹线筋的一端与所述内支撑结构230连接，且位于所述第一内夹线筋210的上方，所述第二内夹线筋和所述第一内夹线筋210之间形成第二内绕线间隙(图未示)，所述内线圈绕组220设置于所述第二内绕线间隙(图未示)内。
具体地，本实施例中，第二内夹线筋的形状与第一内夹线筋210的形状相似，也具有平直段和弧形段。第二内夹线筋对应第一内夹线筋210设置，使得第二内夹线筋和第一内夹线筋210之间形成具有平直段和弧形段的第二内限位间隙。为了提高第二内限位间隙中线圈绕组的稳定性，第一内夹线筋210的宽度大于第二内夹线筋的宽度，第一内夹线筋210的长度大于第二内夹线筋的长度。多个第二内夹线筋沿内支撑结构230的周向，与第一内夹线筋210对应排布，使得第二内限位间隙沿内支撑结构230的周向排列 呈圆环。内线圈绕组220在绕制过程中，只需要将漆包线夹持与第一内绕线间隙240和第二绕线间隙中即可。使得漆包线可以简单、可靠的绕制在第一内绕线间隙240和第二绕线间隙内。在第二内绕线间隙(图未示)中的绕组以密绕为例。通过第二内夹线筋的设置，在线圈绕组的中部形成了双层线圈结构(上、下两层均为密绕)，有利于大幅的提高内加热区200的加热效率。
为了提高内加热区200的加热效率和充分合理的利用空间的同时，简化线圈盘的加工工艺，所述线圈盘还包括内隔离筋，多个所述内隔离筋沿所述第一内夹线筋210的长度方向排列，以在第一内夹线筋210上形成多个沿所述第一内夹线筋210长度方向排列的内绕线槽。
具体地，本实施例中，内隔离筋的横截面的形状可以有多种，如三角形、方形等多边形。内隔离筋可以沿第一内夹线筋210的宽度方向延伸，内隔离筋呈凹弧延伸，以使多个内隔离筋可以围合形成圆环。同一第一内夹线筋210上的内隔离筋沿第一内夹线筋210的长度方向排列，相邻第一内夹线筋210上相同位置的内隔离筋沿内支撑结构230的周向排列，以形成沿内支撑结构230周向延伸的内绕线槽。同一内绕线槽内可以绕制的线圈数量可以根据需求进行设置，如1圈、2圈、3圈等均可。通过内绕线槽形成内线圈绕组220以疏绕为例。第一内夹线筋210、内隔离筋和内支撑结构230之间的连接，可以为相互可拆卸(通过螺钉、卡扣或者胶粘等)连接，也可以一体成型设置。相较于同时设置第一内夹线筋210和第二内夹线筋的方案，设置第一内夹线筋210和内隔离筋的方案更加容易实现。通过内隔离筋的设置，在线圈绕组的中部形成了双层线圈结构(下层为密绕、上层为疏绕)，有利于大幅的提高内加热区200的加热效率。
为了进一步提高外加热区300的加热效率，在所述外加热区300绕制有外线圈绕组330，所述外线圈绕组330具有位于外加热区300中部的外平面加热绕组331，和位于边缘且向上倾斜设置外斜面加热绕组332；外部磁条400包括对应所述外平面加热绕组331设置的外平面段410，和对应外倾斜加热绕组设置的外倾斜段420。
具体地，本实施例中，外线圈绕组330靠近外支撑结构340的部分呈水平设置，四周的部分自水平的部分向上倾斜延伸。即外线圈绕组330中部的部分排列呈平面(外平面加热绕组331)，外线圈绕组330边缘的部分自平面部分向上排列呈倾斜面(外斜面加热绕组332)。其中，倾斜指的延伸趋势，因此具体的实现方式有很多，如平面倾斜、弧面倾斜、波浪面倾斜等均可。在外线圈绕组330的径向方向上，倾斜部分的线圈密度大于平面部分的线圈密度。通过将外部磁条400设置于外斜面加热绕组332对应的外倾斜段420，使得外倾斜段420补偿外斜面加热绕组332的磁场强度，以使外斜面加热绕组332和外平面加热绕组331所在区域的磁场强度相当，从而有利于均匀加热。另外，通过外斜面加热绕组332的设置，在增加外加热区300边缘加热效率的同时，使得外斜面加热绕组332距离锅具更近，有利于对锅具的加热。
另外，为了提高线圈盘外加热区300的加热均匀性，所述外部磁条400的宽度沿所述外加热区300的中部至边缘的方向逐渐增加。随着外部磁条400宽度的增加，使得磁场强度也随着磁条的延伸方向增加，如此，刚好对面积逐渐增加的外线圈绕组330进行补偿，大幅的减小了相邻两外部磁条400之间的距离差，使得外加热区300的中部和周边的加热效率相当。
在一些实施例中，为了进一步提高线圈盘外加热区300域的加热效率，所述外斜面加热绕组332呈弧形设置，所述外倾斜段420对应所述外斜面加热绕组332呈弧形设置，以使所述外倾斜段420与所述外斜面加热绕组332之间的距离，与外平面段410至外平面加热绕组331之间的距离相当。
本实施例中，将外斜面加热绕组332设置呈凹弧形在不影响外平面加热绕组331工作的情况下，在有限的高度外增加了线圈绕组的数量，从而在有限的高度空间外增加了外斜面加热绕组332的工作效率。通过将外倾斜段420沿外斜面加热绕组332弧形延伸， 使得外倾斜段420不仅仅为外斜面加热绕组332提供足够的磁场强度，也保持有相当于外平面段410至外平面加热绕组331之间的距离，使得外斜面加热绕组332和外平面加热绕组331的加热效果相当，有利于均匀加热。
为了提高外线圈绕组330的安装稳定性和便捷性，所述内加热区200域和所述外加热区300域之间的位置设置有外支撑结构340；外支撑结构340上设置有第一外夹线筋310；第一外夹线筋310与线圈支架100之间形成第一外绕线间隙350，所述外线圈绕组330设置于所述第一外绕线间隙350内。其中，第一外夹线筋310的形状可以有很多，以具有平直段和弧形段为例，使得第一外绕线间隙350也可以具有平直段与弧形段，从而与外线圈绕组330的外平面加热绕组331和外斜面加热绕组332对应。
第一外夹线筋310的一端与外支撑结构340固定连接，另一端自外支撑结构340向外加热区300的边缘延伸，使得第一外夹线筋310、外支撑结构340和线圈支架100围合形成第一外绕线间隙350。多个第一外夹线筋310沿支撑结构排列成环形，使得第一外绕间隙排列成环形，如此，有利于外线圈绕组330的绕制。使得外线圈绕组330的形状可以通过调整第一外夹线筋310的排列来实现。外线圈绕组330在绕制过程中，只需要将漆包线夹持与第一外绕线间隙350中即可。使得漆包线可以简单、可靠的绕制在第一外绕线间隙350外。在第一外绕线间隙350中的绕组以密绕为例。
为了提高外加热区300的加热效率，充分合理的利用空间，缩小线圈盘的面积，所述线圈盘还包括第二外夹线筋320，所述第二外夹线筋320的一端与所述外支撑结构340连接，且位于所述第一外夹线筋310的上方，所述第二外夹线筋320和所述第一外夹线筋310之间形成第二外绕线间隙360，所述外线圈绕组330设置于所述第二外绕线间隙360内。
具体地，本实施例中，第二外夹线筋320的形状与第一外夹线筋310的形状相似，也具有平直段和弧形段。第二外夹线筋320对应第一外夹线筋310设置，使得第二外夹线筋320和第一外夹线筋310之间形成具有平直段和弧形段的第二外限位间隙。为了提高第二外限位间隙中线圈绕组的稳定性，第一外夹线筋310的宽度大于第二外夹线筋320的宽度，第一外夹线筋310的长度大于第二外夹线筋320的长度。多个第二外夹线筋320沿外支撑结构340的周向，与第一外夹线筋310对应排布，使得第二外限位间隙沿外支撑结构340的周向排列呈圆环。外线圈绕组330在绕制过程中，只需要将漆包线夹持与第一外绕线间隙350和第二绕线间隙中即可。使得漆包线可以简单、可靠的绕制在第一外绕线间隙350和第二绕线间隙外。在第二外绕线间隙360中的绕组以密绕为例。通过第二外夹线筋320的设置，在线圈绕组的中部形成了双层线圈结构(上、下两层均为密绕)，有利于大幅的提高外加热区300的加热效率。
为了提高外加热区300的加热效率和充分合理的利用空间的同时，简化线圈盘的加工工艺，所述线圈盘还包括外隔离筋370，多个所述外隔离筋370沿所述第一外夹线筋310的长度方向排列，以在第一外夹线筋310上形成多个沿所述第一外夹线筋310长度方向排列的外绕线槽371。
具体地，本实施例中，外隔离筋370的横截面的形状可以有多种，如三角形、方形等多边形。外隔离筋370可以沿第一外夹线筋310的宽度方向延伸，外隔离筋370呈凹弧延伸，以使多个外隔离筋370可以围合形成圆环。同一第一外夹线筋310上的外隔离筋370沿第一外夹线筋310的长度方向排列，相邻第一外夹线筋310上相同位置的外隔离筋370沿外支撑结构340的周向排列，以形成沿外支撑结构340周向延伸的外绕线槽371。同一外绕线槽371外可以绕制的线圈数量可以根据需求进行设置，如1圈、2圈、3圈等均可。通过外绕线槽371形成外线圈绕组330以疏绕为例。第一外夹线筋310、外隔离筋370和外支撑结构340之间的连接，可以为相互可拆卸(通过螺钉、卡扣或者胶粘等)连接，也可以一体成型设置。相较于同时设置第一外夹线筋310和第二外夹线筋320的方案，设置第一外夹线筋310和外隔离筋370的方案更加容易实现。通过外隔 离筋370的设置，在线圈绕组的中部形成了双层线圈结构(下层为密绕、上层为疏绕)，有利于大幅的提高外加热区300的加热效率。
参照图35至图45，在本申请实施例中，该线圈盘座100包括：
基盘110，所述基盘110具有绕线区域；
限位片120，所述限位片120设置于所述基盘110上，所述限位片120与所述绕线区域的内侧壁或者外侧壁之间形成供线圈安装的绕线间隙。
具体地，本实施例中，基盘110的形状可以有多种，如呈平板状、弧形板状或者由底部、侧壁等多个部分组成的立体结构等均可。本实施例中，以基盘包括底部及自底部向上延伸的侧壁为例，绕线区域可以设置在基盘110上的任何所需要的区域，如底部，侧壁等。绕线区域为线圈盘座100工作时，使锅具等产生热量的区域，线圈绕制在绕线区域。
限位片120的形状可以有很多，可以根据不同形状的基盘110选择不同形状限位片120，也可以根据不同的工况需求来设置限位片120的形状，本实施例中，以呈长条形设置为例。限位片120的一端与基盘110连接，另一端沿基盘110的延伸方向延伸。限位片120由绝缘材质制成，如硬质塑料等。限位片120与基盘110的连接方式可以有很多，如通过螺钉连接、卡扣连接、胶粘等，当然，在一些实施例中，也可以将限位片120与基盘110一体成型设置。
限位片120可以设置在基盘110的内侧面，也可以设置在外侧面，当限位片120设置于基盘110的内侧面时，限位片120与基盘110的内侧壁之间形成绕线间隙，当限位片120设置于基盘110的外侧面时，限位片120与基盘110的外侧壁之间形成绕线间隙。当线圈绕制到绕线间隙中时，线圈被限位片120和基盘110的侧壁夹紧，使得线圈固定。
本实施例中，通过在基盘110上设置限位片120，以在限位片120和基盘110的内侧壁或者外侧壁之间形成绕线间隙，线圈缠绕在绕线间隙中，使得线圈被基盘110的侧壁和限位片120夹持，从而实现对线圈的固定，相较于现有的固定方式，线圈的固定不需要使用胶水，从而在线圈发热时也不会产生异味，有利于用户的使用；另外，通过该种方式绕制和固定线圈的效率大幅增加，绕制后的线圈稳定性的得到大幅增加。
为了进一步提高线圈安装的稳定性，所述限位片120的数量为多个，多个所述限位片120沿所述基盘110的周向间隔排布。通过将多个限位片120沿基盘110的周向排布，使得多个限位间隙沿基盘110的周向排布，如此，使得线圈在其延伸方向上多处被限位片120和基盘110夹持，从而使得线圈的安装更加稳定可靠。
值得说明的是，在一些实施例中，限位片120的排布形状即为线圈的绕制形状，可以通过设置限位片120的排布形状来实现线圈的形状(第一圈线圈位于限位片120与基盘110的连接处，线圈在此基础上进行绕制)。如此，在制造线圈盘的过程中，更加有利于便捷、可靠的控制线圈的形状。
下面以一种具体的基盘110结构为例，对线圈盘的结构进行具体的说明，所述基盘110具有收容腔，所述绕线区域包括位于所述基盘底部的底部绕线区，和位于所述基盘侧壁112上的周侧绕线区。本实施例中，基盘110包括底部和围设在底部周缘的周侧壁，周侧壁自底部的周缘向底部的一侧延伸，以围合形成供待加热容器(如锅具)安装的收容腔。为了更加均匀的对待加热容器进行加热，或者为了实现更多的加热方式，在基盘的底部和周侧壁上均设置有绕线区域。
为了提高线圈安装的稳定性，所述限位片120包括底部限位片121，所述基盘的底部设置有向所述基盘内部延伸的支撑结构125；所述底部限位片121的一端与所述支撑结构125固定连接，另一端沿所述基盘底面111延伸，以在所述底部限位片121和基盘底面111之间形成底部绕线间隙123。
本实施例中，支撑结构125的形状可以有很多，以呈柱状设置为例，凡是可以为底部限位片121提供连接，并且连接点与基盘底面111之间具有间隙的结构均可。支撑结 构125设置底部中间的位置，并且向基盘的中部延伸，多个底部限位片121自支撑结构125向四周辐射。底部限位片121与支撑结构125连接的位置可以根据绕线的径向尺寸来设置，不同的连接位置，决定着底部绕线间隙123不同的尺寸。绕线的径向尺寸越大，底部绕线间隙123越大，绕线的径向尺寸越小，底部绕线间隙123越小。底部限位片121的另一端沿底面111延伸，使得底部绕线间隙123均匀，当绕线进入到底部绕线间隙123时，不论在哪个位置，绕线均可以被稳定的夹持。另外，通过将支撑结构125和底部限位片121设置在基盘的内部，使得限位片120的工作尽可能少的受到外部环境的干扰，使得限位片120的稳定性得到提高。
在一些实施例中，所述基盘的底部对应所述底部限位片121的位置开设有底部散热口113。底部散热口113的形状和尺寸与底部限位片121的形状和尺寸相当，底部散热口113位于底部限位片121的正下方。通过底部散热口113的设置，使得底部限位片121可以非常好的散热，有利于底部绕线区的稳定工作。同时，通过底部散热口113的设置，使得底部限位片121在与基盘110一体成长的工艺中，降低底部限位片121形成工艺的难度，即底部散热口113的设置有利于底部限位片121的形成。
为了提高侧部线圈安装的稳定性，所述限位片120包括侧壁限位片122，所述基盘侧壁112上设置有向所述基盘110内部延伸的筋条126；所述侧壁限位片122的一端与所述支筋条126固定连接，另一端沿所述基盘的侧壁112自下而上延伸，以在侧壁限位片122和基盘侧壁112之间形成侧壁绕线间隙124。
本实施例中，筋条126的形状可以有很多，以呈圆环状设置为例，凡是可以为侧壁限位片122提供连接，并且连接点与基盘侧壁112之间具有间隙的结构均可。筋条126设置底部的边缘位置，并且向上延伸，多个侧壁限位片122自筋条126的不同位置沿基盘110的内侧壁延伸。侧壁限位片122与筋条126连接的位置可以根据绕线的径向尺寸来设置，不同的连接位置，决定着侧壁绕线间隙124不同的尺寸。绕线的径向尺寸越大，侧壁绕线间隙124越大，绕线的径向尺寸越小，侧壁绕线间隙124越小。侧壁限位片122的另一端沿基盘110的内侧壁延伸，使得侧壁绕线间隙124均匀，当绕线进入到侧壁绕线间隙124时，不论在哪个位置，绕线均可以被稳定的夹持。另外，通过将筋条126和侧壁限位片122设置在基盘110的内部，使得限位片120的工作尽可能少的受到外部环境的干扰，使得限位片120的稳定性得到提高。
在一些实施例中，所述基盘110的底部对应所述侧壁限位片122的位置开设有侧壁散热口114。侧壁散热口114的形状和尺寸与侧壁限位片122的形状和尺寸相当，侧壁散热口114位于侧壁限位片122的外侧。通过侧壁散热口114的设置，使得侧壁限位片122可以非常好的散热，有利于侧部加热区的稳定工作。同时，通过侧壁散热口114的设置，使得侧壁限位片122在与基盘110一体成长的工艺中，降低侧壁限位片122形成工艺的难度，即侧壁散热口114的设置有利于侧壁限位片122的形成。
值得说明的是，基盘110的内侧壁可以有很多的形状，以呈弧形设置为例，所述基盘110的内侧壁呈凹弧设置，所述侧壁限位片122呈凹弧设置，以使所述侧壁绕线间隙124沿所述侧壁限位片122的长度方向均匀设置。本实施例中，侧壁限位片122的形状和基盘内侧壁的形状相当，并且二者的曲率相当，使得侧壁绕线间隙124非常的均匀，有利于绕线的稳定安装。
在一些实施例中，为了进一步的提高线圈绕线的稳定性，所述基盘110的中部形成有内绕线槽131，所述内绕线槽131的底部开设有内引线310孔以供内引线310穿过，以使内引线310被内绕线槽131中的绕线压紧，和/或，所述基盘110的边缘形成有外绕线槽132，以供绕线结束后的外引线320安装。
本实施例中，内绕线槽131形成的方式有多种，可以直接在基盘110上开设，也可以通过在基盘110上设置零部件来形成，如通过设置多根限位筋条126来围合形成。内绕线槽131的长度可以需求进行设置，如，1/4圆环，1/2圆环，完整的圆环等均可。值 得说明的是，内引线310为绕线的进线端所引出的导线，外引线320为绕线的出线端所引出的导线。内引线310首先自内绕线槽131经过内引线310孔穿出内绕线槽131，绕线再在内绕线槽131内缠绕，缠绕在内绕线槽131中的绕线(绕线至少包括第一绕线圈)，压在内引线310的上方，如此设置，使得内引线310端可以非常稳定的固定，从而避免了绕线在延伸方向上发生位移而导致尺寸误差，有利于提高绕线线圈的精度。值得说明的是，内绕线槽131与底部绕线间隙123之间具有间距，内绕线槽131和底部绕线间隙123之间通过导线的过渡段330连接，如此，既可以保证绕线线圈的位置和数量的准确，又可以根据需求设置内绕线槽131的位置，有利于提高线圈盘座100结构布局的合理性，有利于提高线圈盘座100使用的稳定性。
同理，外绕线槽132的形成方式也可以如内绕线槽131有多种，其长度也可以为1/4圆环，1/2圆环，完整的圆环。外绕线槽132设置在基盘110的边缘，以便绕制结束后的绕线固定。在一些实施例中，为了进一步的便于外引线320的固定，外绕线槽132形成位置高于内绕线槽131的位置，使得外绕线槽132更加的靠近绕线将要完成的位置。在绕制将要结束时，绕线沿外绕线槽132延伸，在外绕线槽132内至少设置有最后一绕线圈，绕线完成之后，外引线320从外绕线槽132延伸出来。
线圈盘通常还包括与线圈盘组配合的盘座200，盘座200与线圈盘组固定连接。当基盘110具有收容腔时，盘座200安装于收容腔中，磁条对应绕制线圈设置。具体地，所述盘座200的底部设置有内限位凸筋210，所述内限位凸筋210远离所述盘座200的一侧安装于基盘110的内绕线槽131内；和/或，所述盘座200的底部设置有外限位凸筋220，所述外限位凸筋220远离所述盘座200的一侧安装于基盘110的外绕线槽132内。在盘座200面向基盘110的一侧，对应内绕线槽131设置有内限位凸筋210，对应外绕线槽132设置有外限位凸筋220。当绕线结束后，内限位凸筋210安装至内绕线槽131中，以压制和限位内引线310，从而达到进一步(对竖直方向进行限位和增加压紧强度)限制内引线310的目的；外限位凸筋220安装至外绕线槽132中，以压制和限位外引线320，从而达到进一步(对竖直方向进行限位和增加压紧强度)限制外引线320的目的。
可以理解的是，在另外一些实施例中，参见图46～图52，还有很多可以固定内引线310和外引线320的方式，以实现对内引线310的进一步的固定。下面举两个例子进行说明：
通过定位孔127的定位，基盘110的底部开设有贯穿所述基盘110的定位孔127，以供内引线310在绕线前穿过紧固。定位孔127的孔径为2～10mm，定位孔127中心与底部绕线间隙123(底部限位间隙123与靠近支撑结构125的位置)之间的距离L为0～6mm，定位孔127位于底部绕线间隙123的内侧；定位孔127上表面与靠近底部绕线间隙123的基盘110表面持平或略低，距离范围0～6mm(如此设置有利于内引线310进入并穿过定位孔127)；定位孔127的底面不超过基盘110的底面，如此设置有利于内引线310从定位孔穿出。
通过扣线槽128固定，基盘110的底部开设有扣线槽128，以供内引线310在绕线前安装紧固。具体地，在底部绕线间隙123的内侧设置一个扣线槽128，扣线槽128开口设置在顺时针方向，线槽挡筋129设置在逆时针方向；线槽挡筋129上表面与靠近底部绕线间隙123的基盘110表面持平或略低距离范围0～6mm(如此设置有利于内引线310进入并穿过扣线槽128)，线槽挡筋129底面不超过基盘110底面，如此设置有利于内引线310从扣线槽128伸出；扣线槽128为开口式的，扣线槽128和线槽挡筋129形状不限于长条形，可为圆形、方形等。
本申请还提出一种线圈盘，该线圈盘包括盘座200和线圈盘座100，该线圈盘座100的具体结构参照上述实施例，由于本线圈盘采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，所述盘座200与所述线圈盘座100连接。
本申请还提出一种烹饪炊具，参照图53至图57，该烹饪炊具包括线圈盘或者线圈盘座100，该烹饪炊具的具体结构参照上述实施例，由于本烹饪炊具采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。值得说明的是，烹饪炊具可以为电饭煲、电磁炉、电烤炉、微波炉、电烤箱等使用线圈电磁加热的烹饪设备。
在一些实施例中，为了提高底座400与线圈盘连接的便捷性，所述烹饪炊具包括底座400，所述底座400上设置有定位柱410；线圈盘座100或者盘座200上对应所述定位柱410设置有定位孔260；所述烹饪炊具还包括紧固件420，所述紧固件420与穿过所述定位孔260的定位柱410固定连接。
具体地，本实施例中，定位柱410竖直向上设置，定位柱410横截面的形状可以有很多，如圆形、椭圆形以及多边形等，以呈圆形设置为例。以定位孔260开设在当线圈盘座100上为例，当线圈盘座100安装至底座400上时，定位孔260套设在定位柱410上。紧固件420与定位柱410固定连接，以防止定位柱410从定位孔260中脱落。如此，大幅的简化了线圈盘座100与底座400之间的装配工艺，有利于提高线圈盘座100的装配效率。
其中，为了更好的对线圈盘座100进行定位，所述定位柱410为阶梯柱，所述定位孔260为阶梯孔，所述定位柱410的阶梯与所述定位孔260的阶梯抵接，以限定所述底座400与所述线圈盘座100或者盘座200的距离。阶梯轴的大径端位于下部，小径端位于上部；阶梯孔的大径端位于下部，小径端位于上部。阶梯轴大径端的顶部与阶梯孔的大径端的顶部抵接，以支撑线圈盘座100，从而可以通过设置阶段的具体尺寸实现底座400与线圈盘座100之间的距离。
其中，紧固件420与固定柱连接的方式可以有很多，如通过卡扣连接，直接卡接、胶粘连接等均可。在一些实施例中，为了进一步提高连接效率，将定位柱410伸出定位孔260，然后在压力和/或高温的作用下，使得伸出的定位柱410发生形变，以使形变部分的尺寸大于定位孔260的孔径，从而实现定位柱410和定位孔260的固定。具体地，所述紧固件420由所述定位柱410伸出所述定位孔260的部分通过挤压和/或熔融的方式变形而成。本实施例中，以热压工艺为例，即对定位柱410伸出的部分同时进行加热和加压。如此，进一步大幅的简化了线圈盘座100与底座400的连接工艺，有利于进一步提高烹饪炊具的装配效率。
本申请提出一种线圈盘，该线圈盘具有不规则形状的加热区，从而能够使得加热效果更均匀。
在本申请一实施例中，如图58和图59所示，该线圈盘包括盘座100和第一线圈绕组200，所述盘座100的周侧壁上设有第一绕线槽，所述第一线圈绕组200沿预设轨迹绕制于所述第一绕线槽中，所述第一线圈绕组200呈异形设置，以提高所述线圈盘加热效果的均匀性。
在此需要说明的是，第一线圈绕组200呈异形设置至少包括如下两方面，第一，第一线圈绕组200在盘座的周侧壁的高度方向上呈异形设置，如此，第一线圈绕组200能够形成具有高度差的多个加热区，进而能够提高线圈盘加热效果的均匀性；第二，第一线圈绕组200的整体形状呈异形设置，例如，第一线圈绕组200可以呈椭圆形设置或呈多边形设置，如此，第一线圈绕组200可以适配椭圆形的加热器具或多边形的加热器具，进而能够使得加热器具与线圈绕组的间距较小，因此能够使得加热器具的加热效果更为均匀。
具体地，如上两方面的效果将在下文的第一实施例和第二实施例中进行详细说明。
在本申请第一实施例中，所述预设轨迹具有峰部和谷部，所述峰部和所述谷部之间具有高度差，以使所述第一线圈绕组200形成具有高度差的多个加热区。
由于本申请提出的线圈盘的第一线圈绕组200沿预设轨迹绕制于所述第一绕线槽中， 所述预设轨迹具有峰部和谷部，所述峰部和所述谷部之间具有高度差，因此能够形成具有高度差的多个加热区，如此，能够将加热区进行分解，即：磁场最强区域由原来的一个中间位置变成了峰部加热区和谷部加热区两个加热位置，峰部加热区的磁场最强区域集中在峰部加热区的中间加热位置，谷部加热区的磁场最强区域集中在谷部加热区的中间加热位置，而峰部加热区和谷部加热区之间具有高度差，两者的中间加热位置高度不同，因此能够进一步地改善线圈盘加热效果的均匀性。
进一步地，请参照图2和图3，现对所述第一线圈绕组200的结构进行说明。本实施例中，所述第一线圈绕组200包括沿所述盘座100的高度方向依次绕制的上半圈绕组210、过渡绕组220和下半圈绕组230；所述上半圈绕组210形成第一加热区，所述过渡绕组220形成第二加热区，所述下半圈绕组230形成第三加热区。由于第一加热区、第二加热区和第三加热区在所述盘座100的高度方向上依次分布，因此，第一加热区、第二加热区和第三加热区的磁场最强区域的高度不同，进而能够使得第一加热区、第二加热区和第三加热区的高温加热区域的高度不同，因此能够改善线圈盘在盘座100的高度方向上加热效果的均匀性。
进一步地，请继续参照图59和图60，为了进一步提高线圈盘加热效果的均匀性，本申请一实施例中，所述上半圈绕组210、所述过渡绕组220和所述下半圈绕组230沿所述盘座100的周向呈错开设置，如此，能够进一步地改善所述第一加热区、所述第二加热区所述第三加热区在盘座100的周向上的加热效果的均匀性。
然本申请的设计不限于此，在其他实施例中，所述第一线圈绕组200还可以包括沿所述盘座100的高度方向依次绕制的N个第一半圈绕组，N为大于等于4的正整数；另外，所述第一线圈绕组200还可以包括沿所述盘座100的周向依次绕制的M个第二半圈绕组，M为大于等于2的正整数。
进一步地，请仍参照图59和图60，现对所述第一线圈绕组200的结构进行详细说明。本实施例中，所述第一线圈绕组200包括多个呈嵌套设置的不规则环形线圈，每一所述不规则环形线圈包括多组依次连接的上段、过渡段和下段；多个所述不规则环形线圈的上段组成所述上半圈绕组210，多个所述不规则环形线圈的过渡段组成所述过渡绕组220，多个所述不规则环形线圈的下段组成所述下半圈绕组230。
具体地，本实施例中，多个所述不规则环形线圈首末端依次相连，每一不规则环形线圈可分割为多组依次连接的上段、过渡段和下段。
进一步地，为了提高第一线圈绕组200的磁感线强度，本申请一实施例中，所述盘座100还包括磁条支架400，所述磁条支架400上设置有磁条500；所述磁条500对应所述上半圈绕组210和/或所述下半圈绕组230设置。
具体地，如图60所示，在第一实施例中，所述磁条500对应所述上半圈绕组210设置；如图61所示，在第二实施例中，所述磁条500对应所述下半圈绕组230设置；如图62所示，在第三实施例中，所述磁条500对应所述上半圈绕组210和下半圈绕组230设置，由于磁条500对应上半圈绕组210和/或下半圈绕组230设置，磁条500对上半圈绕组210和/或下半圈绕组230产生的磁感线具有收束的作用，因此可使磁感线的聚集密度更大，因此能够使得单位面积的加热器具(图未示)接触更多的磁感线，从而能够提高线圈盘的加热速率。
然本申请的设计不限于此，在其他实施例中，所述磁条500还可以对应过渡绕组220设置。
进一步地，请参照图63和图64，所述盘座100的底壁上设有第二绕线槽，所述第二绕线槽中绕制有第二线圈绕组300。如此，底部的第二线圈绕组300与侧壁的第一线圈绕组200能够使得加热器具的底部和侧壁同时受热，如此，能够实现翻滚加热，使得线圈盘加热效果更为均匀。
作为一种优选方式，本申请一实施例中，所述第二线圈绕组300包括多个子线圈绕 组(图未示)。优选地，本实施例中，多个所述子线圈绕组的形状被配置为全面覆盖所述盘座100的底部，例如，本实施例中，盘座100的底部呈圆形，线圈绕组包括两个半圆形的子线圈绕组或四个90°扇形的子线圈绕组。
进一步地，请继续参照图64，本申请一实施例中，所述第二线圈绕组300呈同心圆形，且所述第二线圈绕组300为疏绕线圈绕组，即所述第二线圈绕组300疏绕而成。疏绕和密绕是线圈绕组常见的两种绕制方式，其中，密绕方式的优点是线与线之间紧贴，磁场强，面积大，效率高；密绕方式的缺点是散热差，且漆包线容易产生短路风险。疏绕方式的优点是绕线方便、散热效果好、不易产生短路风险、品质便于管控；疏绕方式的缺点是绕组占用的空间相对于密绕要大些，一方面降低了绕组间的耦合度，漏感会比密绕大；另一方面疏绕的线间分布电容较大，对工作在较高频率的高频变压器损耗也会加大。
本实施例中，所述第二线圈绕组300呈同心圆形，且第二线圈绕组300采用疏绕工艺绕制而成，如此，第二线圈绕组300的散热效果好，品质便于管控。然本申请的设计不限于此，在其他实施例中，如图63所示，所述第二线圈绕组300还可以呈多边形设置，所述第二线圈绕组300可以由疏绕或密绕工艺绕制而成。
进一步地，在本申请第二实施例中，请参照图65至图67，考虑到常规线圈盘的盘座100大多呈碗形设置，因此只能适用圆形的加热器具10(如锅具)，为了使得线圈盘可以适配不同形状的锅具，本实施例中，所述第一线圈绕组200呈椭圆形设置或呈多边形设置，如此，第一线圈绕组200可以适配椭圆形的加热器具或多边形的加热器具，进而能够使得加热器具与线圈绕组的间距较小，因此能够使得加热器具的加热效果更为均匀。本实施例中，所述多边形包括四边形、六边形和八边形等形状。
作为一种优选方式，所述盘座100内设有放置加热器具的容置腔，所述容置腔被配置为与所述加热器具的形状适配；所述第一线圈绕组200绕制在所述容置腔的外周壁上。具体地，本实施例中，所述容置腔可以呈椭圆形或多边形设置。
本申请还提出一种烹饪器具(图未示)，该烹饪器具包括所述线圈盘，该线圈盘的具体结构参照上述实施例，由于本申请提出的烹饪器具采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在此需要说明的是，本实施例中，所述烹饪器具为电饭煲，在其他实施例中，所述烹饪器具还可以为电磁炉、电压力锅、炒菜机、电炖锅、破壁机等。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
