Description
【技术领域】
本发明涉及电饭煲技术领域，具体涉及一种IH电饭煲的陶瓷内胆及其制备方法。
【背景技术】
陶瓷煲的最大优点在于受热、散热均匀，可长时间保温，还能更好地保护食材中有保健功能的酚类物质，让食材充分软化、更易消化，且不会刺激肠胃。目前，市面上的陶瓷电饭锅内胆均是采用传统的发热盘加热方式，然而传统的发热盘加热方式是内胆本身不能加热，需要通过热传递这个环节使内胆受热，这种情况下通常出现内胆受热不均匀，导热慢，因此会增加热能损耗，浪费电能，而且煮出来的米饭基本是泡熟的，容易粘锅起锅巴。另一方面，目前市面上的IH电饭煲内胆均是复合多层材料的，虽然导热快，煮出来的米饭也较传统发热盘加热方式的电饭煲香甜可口，但内部都有化工不粘锅涂层，在实际使用过程中，食物与内胆直接接触难免会带有对人体有害物质。
【发明内容】
鉴于以上内容，有必要提供一种IH电饭煲的陶瓷内胆及其制备方法，以解决加热方式受热不均匀、增加热传递，避免有害物质的问题。
为达到上述目的，本发明所采用的技术方案是：一种IH电饭煲的陶瓷内胆，包括有煲体，所述煲体包括有胚体，所述胚体包括有胚身和胚底，其特征在于，所述IH电饭煲的陶瓷内胆还包括有两导磁块，其中一导磁块贴在所述胚身的外表面并位于所述胚身的下部，另一导磁块贴在所述胚底的外表面，所述两导磁块分别包括有内封膜釉、导磁膜及外封膜釉，所述外封膜釉、导磁膜及内封膜釉在指向所述胚体中心的方向上依次排列，并相互紧贴。
优选地，所述胚身上的导磁块绕所述胚身一圈设置，并且与所述胚底的距离为0.8-1.1cm。
优选地，所述煲体还包括有保护层，所述保护层上在所述胚体的内外表面。
优选地，所述保护层为一层釉，由3％高岭土、2％铁、6％锌、12％铝、3％钙、2％钠、10％硅、8％钡、35％锂、7％镍、6％磷、6％铜混合制成。
优选地，所述内封膜釉由10％高岭土、3％铁、4％锌、23％铝、2％钙、3％钠、10％硅、2％钡、36％锂、2％镍、2％磷、3％铜混合制成。
优选地，所述导磁膜由3％铁、4％锌、75％银、8％铜、5％锂、2％镍、3％磷混合制成。
优选地，所述外封膜釉由8％高岭土、2％铁、5％锌、30％铝、3％钙、2％钠、3％硅、2％钡、38％锂、2％镍、5％磷混合制成。
上述IH电饭煲的陶瓷内胆的制备方法包括有以下步骤：
S1：模种制作；
S2：工具模浇注；
S3：加入浆料，压胚，修胚；
S4：烘干后得胚体；
S5：在胚体的内外表面上釉；
S6：第一次上窑，并在1250-1300℃的温度下烧成煲体；
S7：在煲体的外下煲身和煲底涂上内封膜釉，而后第二次上窑，并在830-900℃的温度下烧内封膜釉以使内封膜釉紧贴煲体的外下煲身和煲底；
S8：在内封膜釉的外表面贴上导磁膜，而后第三次上窑，并在830-900℃的温度下烧导磁膜以使导磁膜紧贴在内封膜釉的外表面；
S9：在导磁膜的外表面涂上外封膜釉，而后第四次上窑，并在830-900℃的温度下烧外封膜釉以使外封膜釉紧贴在导磁膜外表面，放凉后即形成IH电饭煲的陶瓷内胆。
优选地，在步骤S6中，在1280℃的温度下烧
优选地，在步骤S7-S9中分别在900℃的温度下烧。
本发明具有以下有益效果：
本发明IH电饭煲的陶瓷内胆底部和侧壁均粘贴导磁膜，使煲胆快速升温，具有很好的热传力和热对流性，当IH电饭煲工作时导磁膜就开始工作，使得内胆自己发热，减少了通过传统加热盘热传递这个环节，从而减少了热能损耗，所以用起来热效率更高，火力也更大，加热更充分，也更省电。本发明是IH系统电饭煲专用的陶瓷内胆，依据IH工作原理，绝对均匀加热，使米饭在煲胆内是持续翻滚的，米饭口感和营养成分都提升到前所未有的高度。

S6：第一次上窑，并在1250-1300℃的温度下烧成煲体；
S7：在煲体的外下煲身和煲底涂上内封膜釉，而后第二次上窑，并在830-900℃的温度下烧内封膜釉以使内封膜釉紧贴煲体的外下煲身和煲底；
S8：在内封膜釉的外表面贴上导磁膜，而后第三次上窑，并在830-900℃的温度下烧导磁膜以使导磁膜紧贴在内封膜釉的外表面；
S9：在导磁膜的外表面涂上外封膜釉，而后第四次上窑，并在830-900℃的温度下烧外封膜釉以使外封膜釉紧贴在导磁膜外表面，放凉后即形成IH电饭煲的陶瓷内胆。
优选地，在步骤S6中，在1280℃的温度下烧。
优选地，在步骤S7-S9中分别在900℃的温度下烧。
本发明IH电饭煲的陶瓷内胆底部和侧壁均粘贴导磁膜，使煲胆快速升温，具有很好的热传力和热对流性，当电饭煲工作时使得内胆自己发热，减少了通过加热盘热传递这个环节，从而减少了热能损耗，所以用起来热效率更高，火力也更大，加热更充分，也更省电。这样，使用本发明电饭煲内胆煮出来的饭，开盖时米饭香扑鼻而来，口感好，有弹性无夹生，米粒看着好，晶莹剔透，粒粒饱满，营养好，释放充分，流失少，味道好，清香甘甜，能让人记忆起童年的柴火饭。
为了更好的说明本发明的特色，使用传统陶瓷电饭煲内胆及本发明IH电饭煲的陶瓷内胆煮相同量的米饭并进行对比分析见表1：
表1传统陶瓷电饭煲内胆的与本发明的煮饭对比
从表1可以看出,比传统的陶瓷电饭煲内胆煮饭时间短、耗电量少，且煮出来的米饭晶莹剔透、有弹性、粒粒饱满、松软、清香甘甜。
上述说明是针对本发明较佳可行实施例的详细说明，但实施例并非用以限定本发明的专利申请范围，凡本发明所提示的技术精神下所完成的同等变化或修饰变更，均应属于本发明所涵盖专利范围。
