Description

电磁炉及其线盘 技术领域
本申请涉及家电领域，尤其涉及一种电磁炉及其线盘。
背景技术
目前，电磁炉已经走进千家万户，因为其无明火、加热的快捷方便等优点，已经越来越多受到用户的欢迎。小家小户的人口组成结构逐渐变多，很多用户使用电磁炉的时间相对来说比较短，例如仅利用电磁炉烧一壶开水，或是炒一个小炒菜，而现有的电磁炉线盘，基本上是采用敞开式结构对磁条进行散热，这样结构的磁体经常是在水已烧开或菜已经炒好时，磁体的温度都还没达到60℃，在这样的温度范围下会导致磁体的功率损耗高，也就是电磁炉的能效利用率低；另外也有的采用将磁体包覆在线盘基座中的方式，但因散热性能太差，电磁炉使用过程中，磁体温度很快就会超过100℃以上，磁体的功率损耗也会高。磁体的工作温度过高或过低都很容易加快其损耗速度，使其损坏程度更大，使其使用寿命大大地缩短，进而降低了电磁炉的使用性能和使用寿命。
发明内容
本申请旨在至少在一定程度上解决上述技术问题之一。
根据本申请的第一方面，本申请提供一种电磁炉线盘，包括：线圈、磁体及基座，所述基座一侧开设有容置所述线圈的线圈槽以及通槽，另一侧开设有容置所述磁体的磁体槽，所述通槽与所述磁体槽相连通。

进一步地，所述通槽呈环状且与线圈槽同心间隔设置。
进一步地，所述通槽呈离散的孔状。
进一步地，所述通槽设置于与所述线圈槽重合的位置或非与所述线圈槽重合的位置。
根据本申请的第二方面，本申请提供一种电磁炉，包括：电磁炉线盘，所述电磁炉线盘包括：线圈、磁体及基座，所述基座一侧开设有容置所述线圈的线圈槽以及通槽，另一侧开设有容置所述磁体的磁体槽，所述通槽与所述磁体槽相连通。
进一步地，所述线圈槽呈环状排布于所述基座上。
进一步地，所述通槽呈环状且与线圈槽同心间隔设置。
进一步地，所述通槽呈离散的孔状。
进一步地，所述通槽设置于与所述线圈槽重合的位置或非与所述线圈槽重合的位置。
本申请的有益效果是：
通过提供一种电磁炉及其线盘，线盘包括：线圈、磁体及基座，所述基座一侧开设有容置所述线圈的线圈槽以及通槽，另一侧开设有容置所述磁体的磁体槽，所述通槽与所述磁体槽相连通。这样，通过通槽使基座上设置线圈一侧空气可与设置磁体一侧空气实现交换，从而增强磁体位置处的散热效果，使磁体周围温度可实现稳定在一个比较理想的区域，减少了磁体的损耗，提高了电磁炉的使用性能和使用寿命。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语 在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度小于第二特征。
下面通过具体实施方式结合附图对本申请作进一步详细说明。
请参考图1-4，本实施例提供一种电磁炉，包括：电磁炉线盘，以及设置于该电磁炉线盘周围的电磁炉基本器件，如控制面板、整体支架、连接线缆等。而下面对本实施例重点的线盘部分进行详细说明。
上述电磁炉线盘包括：线圈1、磁体2及基座3，基座3一侧开设有容置线圈1的线圈槽33以及通槽31，另一侧开设有容置磁体2的磁体槽32，通槽31与磁体槽32相连通。[0027]
这样，通过通槽使基座上设置线圈一侧空气可与设置磁体一侧空气实现交换，从而增强磁体位置处的散热效果，使磁体周围温度可实现稳定在一个比较理想的区域，减少了磁体的损耗，提高了电磁炉的使用性能和使用寿命。
一般情况下，线圈槽33呈环状排布于基座3上。这样，通槽31的设计可有至少如下两种设置方式：
第一种设置方式，通槽31呈环状且与线圈槽33同心间隔设置。这样设计的好处，使得线圈一侧空气能均匀地通过通槽31与磁体一侧空气进行热交换，由于线圈发热较均匀，平衡了磁体由中心到周围的温度变化，使得磁体一侧温度较为平均，按照实验室测量结果，可稳定在80-100度之间，从而进一步减少了磁体的损耗，提高了电磁炉的使用性能和使用寿命。
第二种设置方式，通槽31呈离散的孔状均匀分布于基座的整个表面，同样，能实现将线圈一侧空气与磁体一侧空气进行热交换。而通槽31设置于与线圈槽重合的位置或非与线圈槽重合的位置。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换。
