为了更详细的解释本发明所提出的高效热交换保温容器及加热系统， 以下结合附图及具 体实施例， 对本发明进行详细阐述。 应当理解， 此处所描述的实施例仅仅是用以解释本发明 的设计， 并不用于限定本发明。 实施例 1
请参阅图 1和 2所示， 为本发明其中一实施例的结构示意图， 其适合于容器底部 13用电 热盘和电热板加热方式使用， 如家用电饭煲、 电磁炉等。 本发明的高效热交换电加热保温容 器 10， 其容器底部 13采用单层结构， 直接与金属电热盘 21上表面接触， 保温容器 10的四 周侧壁采用双层结构， 容器外层 11与容器内层 12形成一个环形封闭体。 将环形封闭体抽真 空后注入超导热无机混合物液体材料 14， 然后密封； 或者是在容器成形前， 先在容器内层 12 的外表面涂上厚度为 2至 3毫米的超导热有机固体纳米材料 15 (如图 3所示）， 然后抽真空 和密封。
上述高效热交换电加热保温容器 10的底部还设置有电加热装置 20， 电加热保温容器 10 和电加热装置 20构成（电）加热保温系统。上述容器底部 13放置在金属电热盘 21的上表面， 由于受金属加工精度的限制和金属热变形的影响， 两个接触面不可能完全吻合， 所以存在热 量在传导过程中损失。进一步研究， 金属电热盘 21通电后是整体发热， 其四周和下表面不与 容器底部 13接触， 在热交换过程中也存在热量损失。为了解决现有技术存在上述所分析的缺 点， 在金属电热盘 21的下表面增加一个电热盘导热环 22直接与容器环形封闭体下端的吸热 区接触， 形成了一个贮存热量的环形高温空气区 30， 便可提高对金属电热盘 21产生热量的 利用率。
采用上述本发明高效热交换保温容器及加热系统配合使用， 金属电热盘 21通电后整体发 热， 其上表面产生的热量大部分直接传导给容器底部 13， 少部分热量损失被贮存在环形高温 空气区 30内进行二次利用。
进一步， 圆形金属电热盘 21周边产生的热量也被贮存在环形高温空气区 30内进行二次 利用。
进一步， 金属电热盘 21底部下表面产生的热量通过电热盘导热体环 22传递到容器环形 封闭体下端的吸热区， 便于超导热液体材料 14吸收。
进一步， 电热盘导热环下表面设置高热阻材料保温层 23， 以减少热量损失。
超导热液体材料 14吸收金属电热盘 21底部下表面和环形高温空气 30内的热 ft 温度逐 渐升高， 达到设定值时， 变相产生高温蒸汽向上运动， 高温蒸汽被冷却后变成液体， 在重力 和压力的作用下往下流动， 不断地将金属电热盘 21底部下表面和高温空气区 30内的热量传 递到容器内层 12。
金属电热盘 21断电后， 保温容器 10及电加热装置 20处于降温状态， 超导热液体材料 14将已吸收的热量释放出来， 传递到容器内层 12。 当温度降低到设定值时， 超导热液体材料 14的体积收缩， 使保温容器 10的环形封闭体恢复原有的真空状态， 起到了保温的作用。
此款设计用于家用电饭煲行业， 经测试， 可以达到节能减排的有益效果， 它的环形立体 式加热功能不仅可以提高煮饭的均匀度， 还可以有利于在煮饭过程中对加热曲线的调节与控 制。

Figure imgf000006_0001
表 1是两种技术方案处于同一环境中， 在同一单位时间内耗用电量相等和使用同一种电 热元件的条件下所测得的数据。 如表所示， 加热 2000毫升水， 温度到达 70°C时， 现有技术 需要 758秒钟， 本发明只需要 667秒钟； 温度到达 100°C时， 现有技术需要 1225秒钟， 本发 明需要 1104秒钟， 两者之差时 121秒钟。 与现有技术的加热煲相比， 本发明的电加热保温容 器及电加热系统需要的时间少， 因其能吸收电热盘底部的散发的热量的必然结果。 实施例 2
请参阅图 4和 5所示， 为本实用新型又一实施例的结构示意图， 适合于容器底部 44燃烧 天然气、 液化石油气或煤炭等产生高温废气的燃料场合使用。 本实用新型的高效热交换保温 容器 40的容器底部 44采用单层结构， 直接与热源接触， 容器四周侧壁上半部分采用双层结 构， 分别为容器外层 41和容器上内层 42。 容器四周侧壁下半部分采用三层结构， 分别为容 器外层 41、 容器中层 45和容器下内层 43。 其中， 容器中层 45与容器上内层 42连接， 使容 器外层 41、 容器中层 45和容器上内层 42之间形成真空环形封闭体。 该环形封闭体可注入超 导热液体材料 50或其内层壁面涂有厚度为 2至 3毫米的超导热有机固体纳米材料。该环形封 闭体中间部位的外层与内层设有多个环形出气孔 47。 容器中层 45与容器下内层 43之间设有 空隙 46， 与多个出气孔 47连通。 容器四周侧壁下半部分的下内层 43分别与容器底部 44和 上内层 42连接， 形成一个容器。
如图 6所示， 容器外层 41与容器中层 45之间设计成多个封闭体， 多个封闭体与容器四 周侧壁上半部分的环形封闭体的内腔连通。 容器中层 45与下内层 43之间的空隙 46， 延长了 高温废气与内层进行热交换的时间。
当保温容器 40处于升温状态时， 液化石油气产生的燃烧火焰直接加热容器底部 44， 容 器底部 44再将热量传递给容器 40内的待加热物质。 液化石油气在燃烧过程中产生大量高温 废气， 其含量有一氧化碳、 二氧化碳、 二氧化硫等气体随热运动离开容器底部 44， 受到环形 封闭体吸热区容器中层 45的阻挡通过空隙 46向上运动，由环形封闭体中部的出气孔 47排出。 高温废气在运动的过程中加热了容器下内层 43， 超导热液体材料 50吸收高温度废气的热量， 温度升高， 达到设定值时， 变相产生高温蒸汽向上运动， 高温蒸汽被冷却后变成液体， 在重 力和压力的作用下往下流动， 不断地将高温废气的热量传递到容器上内层 42。
所以， 在整个升温过程中， 本实用新型能充分利用液化石油气燃烧时产生的热量， 对保 温容器 40内的待加热物质进行环形立体式加热有利于节能减排， 关掉液化石油气开关， 保温 容器 40和待加热物质的温度逐渐降低， 超导热液体材料 50将已吸收的热量释放出来， 传递 到容器内层； 温度降低到设定值时， 超导热液体材料 50的体积迅速收缩， 使保温容器 40的 环形封闭体恢复原有的真空状态， 对待加热物质起到了保温的作用。

表 2是两种技术方案处于同一环境中， 在同一单位时间内耗用液化石油气相等和使用同 一个燃气炉具的条件下所测得的数据。 如表所示， 加热 2000毫升水， 温度到达 70°C时， 现 有技术需要 340秒钟， 本发明最差效果只需要 301秒钟； 温度到达 100°C时， 现有技术需要 592秒钟， 本实用新型需要 514秒钟， 两者之差时 78秒钟。 与现有技术的加热煲相比， 本实 用新型实施例的热交换保温容器需要的时间少， 因其能吸收液化石油气在燃烧过程中产生高 温废气的热量的必然结果。
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， 故凡是 未脱离本发明技术方案内容， 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，均仍属于本发明技术方案的范围内。
