Abstract

一种无感锅具及灶具。引入无感线圈(12)用于加热，并将无感线圈(12)设置于锅体(11)内；使得热传导的热惰性基本可以忽略，热传导的效果很好；并且，锅体(11)内表面的温度上升也很快，可以对食物或水快速或瞬间加热；另外，由于热传感效率高，从而使得本身不需要太高的温度，正热阻效应不明显；无感线圈(12)中电流处处相等，不像电磁炉给含铁质锅加热一样，在铁质锅上形成若多个涡旋电流；因而无感线圈(12)中的电流处处相等，热分布均匀；由于无感线圈(12)基本没有电抗，从而无功消耗非常低，锅具的功率可以做得很高。

Description

说明书 发明名称：一种无感锅具及灶具
技术领域
[0001] 本发明涉及一种无感锅具及灶具。
背景技术
[0002] 目前厨房中在炒菜煮饭等吋， 加热的技术手段主要有三种。
[0003] 第一、 使用天然气或管道煤气等作为能源来进行加热， 从而炒菜做饭等。 这种 做法是使用明火发热进行加热， 其缺点主要是管道铺设成本非常高， 尤其是对 于一些旧片区的管道铺设改造。
[0004] 第二、 使用电炉加热来炒菜做饭等。
[0005] 电炉通常包括陶瓷等材料制成的容器以及围绕该容器设置的发热丝， 其原理是 发热丝通电后发热， 并传递给被其围绕的容器， 从而实现对该容器内的食材进 行加热的目的。
[0006] 电炉的缺点是： ①由于热传导的热惰性， 使得热传导的效果不好， 制约了最终 对食材进行加热的温度； 反过来， 要达到一个勉强符合的最终加热温度 （例如 3 00度） ， 则需要热源 （如上述发热丝） 本身的温度很高 （例如 1500度） ； ②发热 丝本身还具有正热阻效应， 即发热丝的电阻会随着温度升高而升高， 而由于电 炉使用过程中发热丝的温度很高， 这使得发热丝的正热阻效应越加明显； 又因 为发热丝实际上不可能是理想的处处电阻相等， 因此由于发热丝的正热阻效应 ， 使得发热丝在实际使用过程中各处的电阻可能相差较大， 造成发热丝电阻大 的地方局部明显温度过高， 长期使用， 十分容易出现问题， 例如老化等。
[0007] 第三、 电磁炉上放含铁质的锅具， 来加热进行炒菜做菜等。
[0008] 电磁炉是基于电磁感应现象而发明的， 即利用交变电流通过线圈产生方向不断 改变的交变磁场， 处于交变磁场中的导体的内部将会出现涡旋电流， 这是涡旋 电场推动导体中载流子运动所致； 涡旋电流的焦耳热效应使导体升温， 从而实 现加热； 具体地， 当用含铁质锅具底部放置炉面吋， 锅具即切割交变磁力线而 在锅具底部金属部分产生交变的电流 （即涡流） ， 涡流使锅具底部铁质材料中 的自由电子呈漩涡状交变运动， 通过电流的焦耳热 （P=I2*R) 使锅底发热； 总 结一句话： 电磁炉采用了磁场感应涡流加热原理， 它利用交变电流通过线圈产 生交变磁场， 当磁场内的磁感线传到含铁质锅的底部吋， 即会产生无数强大的 小涡流， 使锅本身自行迅速发热， 然后再加热锅内的食物。
[0009] 电磁炉加热来炒菜做饭， 其缺点是： ①涡流的发热功率与其材料本身的电阻率 成反比， 而含铁质锅同样具有上述提到的正热阻效应， 即随着含铁质锅本身温 度升高， 其电阻升高， 电阻率升高， 使得涡流在含铁质锅中的发热功率具有上 限， 受到制约； ②电磁炉产生的交流磁场是不均匀的， 涡流在锅底的分布是不均 匀的， 锅的材质也不可能是均匀的， 这三个因素都会导致锅底的温度分布不均 匀， 即有些地方温度高， 有些地方温度低， 从而产生热斑效应； 同吋温度高的 地方， 正热阻效应明显， 导致该处的电阻和电阻率明显变大， 从而使该局部又 进一步升温， 热斑效应越加明显， 也加快了锅的老化问题等； ③锅具在放置于电 磁炉产生的交流磁场中， 其产生的电感很大， 从而无功消耗非常高， 这使得锅 具本身的发热功率上限以及效率受到限制。

[0072]
[0073] 实施例 1
[0074] 请参考图 1和图 2， 本发明一实施例中公幵了一种无感锅具， 该无感锅具包括锅 体 11和无感线圈 12， 无感线圈 12被绝缘地设置于锅体 11内， 下面具体说明。
[0075] 锅体 11用于烹煮食物或烧水等。 在一实施例中， 锅体 11是由导热和 /或耐高温 的材料制成的绝缘体。
[0076] 在一实施例中， 锅体 11包括包括底部和围绕底部设置以形成半封闭空间的围绕 部。 在一实施例中， 无感线圈 12设置于锅体 11的底部内。 在一实施例中， 无感 线圈 12设置于锅体 11的围绕部内。 在一实施例中， 无感线圈 12设置于锅体 11的 底部内且伸延至围绕部。
[0077] 为了更加地安全， 在一实施例中， 锅体 11的内表面和 /或外表面上设置有绝缘 涂层， 用于密封无感线圈 12。
[0078] 为了具有更好的加热效果， 在一实施例中， 锅体 11的外表面上设置有保温涂层
[0079] 无感线圈 12用于加热。 在一实施例中， 无感线圈 12为导体， 例如铜、 铁、 金和 银等金属。 在一实施例中， 无感线圈 12的头尾对接， 从折合处幵始绕制成圆弧 状， 即圆弧的一端为无感线圈 12的折合处， 另一端为无感线圈 12的头尾两端。
[0080] 在一实施例中， 无感线圈 12首尾相连形成通路， 用于感应变化的磁场以产生电 流来发热。 例如， 图 1中的无感线圈 12就是首尾相连形成通路， 通过感应变化的 磁场来产生电流从而发热。 在一实施例中， 无感锅具还可以包括用于给无感线 圈 12提供变化的磁场的装置。
[0081] 在一实施例中， 本发明还公幵了一种灶具， 其包括上述任一实施例的无感锅具 以及用于给无感锅具提供变化的磁场的装置。
[0082] 在一实施例中， 无感锅具还包括电源接口， 该电源接口设置在锅体上， 无感线 圈 12与电源接口电连接， 用于外接电源来发热。 换句话说， 此吋电源接口外接 电源后， 用于给无感线圈 12供电， 无感线圈 12中具有电流， 从而发热。 例如， 图 3所示为当包括电源接口吋无感线圈 12的示例， 此吋无感线圈 12首尾并不相连 ， 而是用于与电源接口电连接。 图 4为包括电源接口的无感锅具的一种示例。
[0083] 由于无感线圈 12被绝缘地设置于锅体 11内， 因而当无感线圈 12发热吋， 热传导 的热惰性基本可以忽略， 热传导的效果很好； 并且， 锅体 11内表面的温度上升 也很快， 可以对食物或水快速或瞬间加热。 另外， 由于热传感效率高， 从而使 得本身不需要太高的温度 （例如 180度） ， 正热阻效应不明显。
[0084] 无感线圈 12中电流处处相等， 不像电磁炉给含铁质锅加热一样， 在铁质锅上形 成若多个涡旋电流； 因而无感线圈 12中的电流处处相等， 热分布均匀。
[0085] 由于无感线圈 12基本没有电抗， 从而无功消耗非常低， 锅具的功率可以做得很 高。
[0086] 本发明的无感锅具可以为炒锅、 汤锅、 压力锅或电饭锅等。 例如图 1和 2所示的 无感锅具较适合用于炒菜等。
[0087] [0088] 实施例 2:
[0089] 请参考图 5， 本发明一实施例中公幵了一种压力锅， 该压力锅包括锅体 21和无 感线圈 22， 无感线圈 22被绝缘地设置于锅体 21内。
[0090] 锅体 21用于烹煮食物或烧水等。 在一实施例中， 锅体 21是由导热和 /或耐高温 的材料制成的绝缘体。
[0091] 在一实施例中， 锅体 21包括底部和围绕底部设置以形成半封闭空间的围绕部。
在一实施例中， 无感线圈 22设置于锅体 21的底部内。 在一实施例中， 无感线圈 2 2设置于锅体 21的围绕部内。 在一实施例中， 无感线圈 22设置于锅体 21的底部内 且伸延至围绕部。
[0092] 为了更加地安全， 在一实施例中， 锅体 21的内表面和 /或外表面上设置有绝缘 涂层， 用于密封无感线圈 22。
[0093] 为了具有更好的加热效果， 在一实施例中， 锅体 21的外表面上设置有保温涂层
[0094] 无感线圈 22用于加热。 在一实施例中， 无感线圈 22为导体， 例如铜、 铁、 金和 银等金属。 在一实施例中， 无感线圈 22的头尾对接， 从折合处幵始绕制成圆弧 状， 即圆弧的一端为无感线圈 22的折合处， 另一端为无感线圈 22的头尾两端。
[0095] 在一实施例中， 无感线圈 22首尾相连形成通路， 用于感应变化的磁场以产生电 流来发热。 例如， 图 5中的无感线圈 22就是首尾相连形成通路， 通过感应变化的 磁场来产生电流从而发热。
[0096] 在一实施例中， 压力锅还包括电源接口， 该电源接口设置在锅体上， 无感线圈 22与电源接口电连接， 用于外接电源来发热。 换句话说， 此吋电源接口外接电 源后， 用于给无感线圈 22供电， 无感线圈 22中具有电流， 从而发热。 例如， 图 6 所示为当包括电源接口吋无感线圈 22的示例， 此吋无感线圈 22首尾并不相连， 而是用于与电源接口电连接。
[0097] 请参照图 7， 一实施例的压力锅还可以包括压力锅盖 23， 压力锅盖 23上可以设 置放气孔、 安全阀， 并配置有密封胶圈等， 压力锅盖 23与锅体 21配合使用， 将 锅体 21的半封闭空间给封闭起来， 从而当加热吋形成高温高压的环境。
[0098] 请参照图 8和图 9， 一实施例的压力锅还可以包括压力锅盖 24以及壳体 25， 压力 锅盖 24上可以设置放气孔、 安全阀， 并配置有密封胶圈等； 壳体 25用于容纳以 及放置锅体 21， 锅体 21放置在壳体上后， 再盖上压力锅盖 24， 可以在锅体 21容 纳的空间中形成一个高温高压的环境。 换句话说， 在本实施例中， 锅体 21此吋 是作为压力锅的内胆。 在一实施例中， 壳体 25上设置有用于给无感线圈 21提供 变化的磁场的单元。
[0099] 由于无感线圈 22被绝缘地设置于锅体 21内， 因而当无感线圈 22发热吋， 热传导 的热惰性基本可以忽略， 热传导的效果很好； 并且， 锅体 21内表面的温度上升 也很快， 可以对食物或水快速或瞬间加热。 另外， 由于热传感效率高， 从而使 得本身不需要太高的温度 （例如 180度） ， 正热阻效应不明显。
[0100] 无感线圈 22中电流处处相等， 不像电磁炉给含铁质锅加热一样， 在铁质锅上形 成若多个涡旋电流； 因而无感线圈 22中的电流处处相等， 热分布均匀。
[0101] 由于无感线圈 22基本没有电抗， 从而无功消耗非常低， 锅具的功率可以做得很 高。
[0102]
[0103] 实施例 3
[0104] 请参考图 10， 本发明一实施例中公幵了一种电饭煲， 该电饭煲包括锅体 31和无 感线圈 32， 无感线圈 32被绝缘地设置于锅体 31内。
[0105] 锅体 31用于烹煮食物或烧水等。 在一实施例中， 锅体 31是由导热和 /或耐高温 的材料制成的绝缘体。
[0106] 在一实施例中， 锅体 31包括底部和围绕底部设置以形成半封闭空间的围绕部。
在一实施例中， 无感线圈 32设置于锅体 31的底部内。 在一实施例中， 无感线圈 3 2设置于锅体 31的围绕部内。 在一实施例中， 无感线圈 32设置于锅体 31的底部内 且伸延至围绕部。
[0107] 为了更加地安全， 在一实施例中， 锅体 31的内表面和 /或外表面上设置有绝缘 涂层， 用于密封无感线圈 32。
[0108] 为了具有更好的加热效果， 在一实施例中， 锅体 31的外表面上设置有保温涂层
[0109] 无感线圈 32用于加热。 在一实施例中， 无感线圈 32为导体， 例如铜、 铁、 金和 银等金属。 在一实施例中， 无感线圈 32的头尾对接， 从折合处幵始绕制成圆弧 状， 即圆弧的一端为无感线圈 32的折合处， 另一端为无感线圈 32的头尾两端。
[0110] 在一实施例中， 无感线圈 32首尾相连形成通路， 用于感应变化的磁场以产生电 流来发热。 例如， 图 10中的无感线圈 32就是首尾相连形成通路， 通过感应变化 的磁场来产生电流从而发热。
[0111] 在一实施例中， 电饭煲还包括电源接口， 该电源接口设置在锅体上， 无感线圈 32与电源接口电连接， 用于外接电源来发热。 换句话说， 此吋电源接口外接电 源后， 用于给无感线圈 32供电， 无感线圈 32中具有电流， 从而发热。 例如， 图 1 1所示为当包括电源接口吋无感线圈 32的示例， 此吋无感线圈 32首尾并不相连， 而是用于与电源接口电连接。
[0112] 请参照图 12、 图 13和图 14， 一实施例的电饭煲还可以包括电饭煲盖 33以及壳体 34， 壳体 34用于容纳以及放置锅体 31。
[0113] 在一实施例中， 当无感线圈首尾相连形成通路用于感应变化的磁场以产生电流 来发热吋， 壳体 25上还设置有用于给无感线圈 32提供变化的磁场的单元。
[0114] 由于无感线圈 32被绝缘地设置于锅体 31内， 因而当无感线圈 32发热吋， 热传导 的热惰性基本可以忽略， 热传导的效果很好； 并且， 锅体 31内表面的温度上升 也很快， 可以对食物或水快速或瞬间加热。 另外， 由于热传感效率高， 从而使 得本身不需要太高的温度 （例如 180度） ， 正热阻效应不明显。
[0115] 无感线圈 32中电流处处相等， 不像电磁炉给含铁质锅加热一样， 在铁质锅上形 成若多个涡旋电流； 因而无感线圈 32中的电流处处相等， 热分布均匀。
[0116] 由于无感线圈 32基本没有电抗， 从而无功消耗非常低， 锅具的功率可以做得很 高。
[0117]
[0118] 以上应用了具体个例对本发明进行阐述， 只是用于帮助理解本发明， 并不用以 限制本发明。 对于本领域的一般技术人员， 依据本发明的思想， 可以对上述具 体实施方式进行变化。
