Description

烹饪器具的盖体结构及烹饪器具 技术领域
本发明涉及厨房用具技术领域，具体涉及一种烹饪器具的盖体结构及烹饪器具。
背景技术
传统的电饭煲，由于通常只是底部加热，使得锅内的温度从下到上逐渐降低，导致煮饭过程中表层的米饭无法充分吸水、沸腾，最终在煮饭结束后，会使得米饭表面偏干、偏硬、周边偏湿，同时也会产生开盖时积水过多的问题。
为解决开盖时积水过多，米饭表面偏干、偏硬、周边偏湿的问题，现有的一种电饭煲，其煲顶结构包括盖合后与内锅直接接触的保温盖板，及位于保温盖板上方的保温座板；该电饭煲是在煲顶增加发热丝，将发热丝与保温座板贴紧后使用双面胶进行固定，发热丝加热后通过将热量传递给保温盖板，使保温盖板可以被加热到一定温度。上述电饭煲虽然可以通过发热丝对保温盖板加热，但是由于发热丝加热的方式会出现局部高温，使得保温盖板受热不均匀，而且发热丝的功率一般相对较小，对米饭的改善效果不大。
公开号为CN202198413U的专利文献公开了一种电磁感应加热电饭煲，包括内锅、煲体和煲盖，煲体和煲盖闭合形成封闭的烹饪腔，内锅位于烹 饪腔中，该电磁感应加热电饭煲还包括位于煲盖下方的顶部加热部件；顶部加热部件为电磁加热装置，并包括顶部绕线盘、电磁诱导线圈和反射板；顶部绕线盘安装于煲盖内，并设置有线槽，电磁诱导线圈缠绕固定在顶部绕线盘的线槽里，反射板与顶部绕线盘将电磁诱导线圈夹紧，作为一个整体固定在煲盖上。上述电磁感应加热电饭煲通过在煲盖上设置电磁加热的顶部加热部件，可以实现对电饭煲上部的加热，进而实现电饭煲上、中、下三维立体均匀加热；但是，上述电磁感应加热电饭煲是将顶部加热部件设置在煲盖下方，即顶部加热部件是整个煲盖结构中最靠近内锅的，这会使得虽然顶部加热部件可以对电饭煲顶部及煲盖进行加热，但是由于顶部加热部件为电磁加热装置，本身是不会发热的，相对于其上方的煲盖及下方的内锅并没有多高的温度，所以直接与内锅腔内接触的顶部加热部件与内锅之间依然存在较大的温差，导致依然存在内锅内的温度从下到上逐渐降低，煮饭过程中表层的米饭无法充分吸水、沸腾，最终在煮饭结束后，会使得米饭表面偏干、偏硬、周边偏湿，同时也会产生开盖时积水过多的问题。
发明内容
因此，本发明要解决的技术问题在于克服现有技术中的烹饪器具烹饪效果不佳，且开盖时易产生较多积水的缺陷，从而提供一种可以有效改善烹饪效果，且开盖时不易产生积水的烹饪器具的盖体结构及烹饪器具。

配合参阅图4，电磁加热装置3包括绕线结构31和导电线圈32。
在本实施例中，导电线圈32安装于绕线结构31靠近锅体的一侧。这样可以使锅腔接触面21处的磁场强度更高，从而获得更好的加热效果。作为可变换的实施方式，导电线圈32也可以安装于绕线结构31远离锅体的一侧。
绕线结构31靠近锅体的一侧设有若干绕线槽311，绕线槽311的槽宽与导电线圈32的外径相匹配，适于对导电线圈32进行单匝卡合。这种单匝卡合的绕线方式，不仅可以使对导电线圈32的绕线更规整，还可以实现自动化绕线，提高绕线效率。
绕线槽311呈环状，且同心设置。在本实施例中，若干同心且等间距设置的绕线槽311形成一环绕线槽结构，绕线结构31上设置有一环绕线槽结构。作为可变换的实施方式，也可以在绕线结构31上设置两环或三环等多环绕线槽结构。这种绕线方式，可以根据空间需求来布置导电线圈32，从而实现在导电线圈32不完全铺满绕线结构31时，也能对所需区域提供足够的磁场强度。
为了便于提高绕线及生产效率，本实施例的绕线结构31上设有绕线工装定位孔312，绕线工装定位孔312处于环状槽结构的圆心处，绕线工装定位孔312可以用于自动绕线工装定位，从而提高绕线及生产效率。
为了使绕线结构31上的走线整洁规范，在本实施例中，绕线结构31上设有第一走线扣位结构313和第二走线扣位结构314；
第一走线扣位结构313设于位置最靠近圆心的绕线槽311的内侧，用于对导电线圈32的引入线或引出线在位置最靠近圆心的绕线槽311内侧进行定位；
第二走线扣位结构314设于位置最远离圆心的绕线槽311的外侧，用于对导电线圈32的引入线和引出线在位置最远离圆心的绕线槽311的外侧进行定位并合并。
为了使盖体上的走线整洁规范，本实施例的盖体上设有可对合并后的导电线圈32的引入线和引出线进行限位的第三走线扣位结构12。在本实施例中，第三走线扣位结构12设置于盖本体1上。
在本实施例中，导电线圈32的引入线与引出线分别与锅体的主板电连接。
本实施例的烹饪器具的盖体结构的工作过程如下：
当烹饪器具通电运行时，导电线圈32通电，产生不断变化的磁场，使导磁的盖板2及其上的锅腔接触面21被高效、均匀地加热，由于锅腔接触面21是在盖体盖合至锅体上时，与锅体内因加热所产生的热蒸汽直接接触的面，所以可以降低甚至消除锅腔接触面21与锅体之间以及与锅体内加热所产生的热蒸汽之间的温差,从而可以改善烹饪效果,同时改善甚至消除烹饪加热后开盖时产生积水的问题。
作为可变换的实施方式，电磁加热装置3也可以同时对盖体和/或锅体的其他需要被加热的结构或部位进行加热。
实施例2
本实施例提供一种烹饪器具，包括实施例1中的烹饪器具的盖体结构，及锅体。
在本实施例中，烹饪器具为电饭煲。通过对电饭煲的与锅体与锅体内因加热所产生的热蒸汽直接接触的锅腔接触面21通过电磁加热装置3进行电磁加热，可以使锅腔接触面21高效、均匀受热,降低甚至消除锅腔接触面21与锅体之间以及与锅体内加热所产生的热蒸汽之间的温差,不仅可以使煮饭过程中上层的米饭可以充分吸水沸腾，避免出现米饭表面偏干、偏硬、周边偏湿的问题,还可以改善甚至消除米饭煮熟后开盖时产生积水的问题。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
