[0001] 本申请是以申请号为 201821129682.6， 申请日为 2018年 7月 16日的中国专利申请 为基础， 并主张其优先权， 该申请的全部内容在此作为整体引入本申请中。
[0002] 技术领域
[0003] 本申请属于电加热技术领域， 尤其涉及一种电加热装置和电焰灶。
[0004] 背景技术
[0005] 目前采用电作为能量来源产生热能用来加热的灶具， 具有方便安全等特点在各 种领域得到广泛应用， 电加热灶具主要有 3种类型产品： 1、 电磁灶； 电磁灶采 用电磁感应原理， 电磁炉的炉面是耐热陶瓷板， 铁磁材质锅具放置在耐热陶瓷 上， 下面放置线圈， 电磁灶的控制电路产生交变电流流过线圈从而产生磁场， 磁场的磁力线穿过铁磁材质锅具底部， 铁磁锅底会产生渦流， 令锅底迅速发热 产生高温， 实现加热功能。 2、 电陶炉； 在锅具的下部放置电阻丝， 电阻丝通电 后发热产生高温， 高温电阻丝发热发光， 主要以热辐射形式加热锅具底部。 3、 卤素灯灶； 在锅具的下部放置卤素灯， 卤素灯通电后发光产生红外热辐射原理 ， 加热物品。
[0006] 但现有的电加热方式的灶具存在以下问题： 1、 电磁加热原理要求锅具必须采 用铁磁材质， 否则不能实现加热功能， 对锅具材质有限制， 一些烹饪形式不能 实现 （比如采用陶瓷容器的一些烹饪方式不能用电磁灶加热） 。 另外铁磁锅具 底部只有正对线圈上部的位置才能产生热， 锅具其它地方没有线圈正对就不会 产生热量， 导致锅具加热均匀性不够， 容易出现锅具有些地方高温， 有些地方 却是冷， 对烹饪产生影响， 达不到燃气加热的“火包锅”非常均匀加热效果。 2、 电陶炉和南素灯灶都是通过热辐射的方式来加热锅具， 这两种加热方式虽然对 锅具材质没有限制， 可以加热各种材质的锅具包括陶瓷容器， 但是辐射加热方 式和传统的燃气火焰加热方式还是有很大的不同， 也不能做到传统燃气加热的“ 火包锅”非常均匀的加热效果。

[0045] 如图 1~8所示， 本申请实施例提供一种电加热装置， 电加热装置包括多个用于 产生电弧以将空气击穿形成等离子气流并对厨具 40进行加热的出气组件 50、 用 于将外部空气输送至出气组件 50的抽气组件 10、 用于对出气组件 50排出的等离 子气流进行隔热的第一隔热件 20和第二隔热件 30, 第一隔热件 20与第二隔热件 3 0间隔设置， 出气组件 50的一端插装于第一隔热件 20上， 出气组件 50的另一端插 装于第二隔热件 30上， 抽气组件 10与出气组件 50连通， 第二隔热件 30的底部的 中部设有一用于改变等离子气流方向的吸引件 32。
[0046] 本申请实施例的电加热装置通过出气组件 50产生的电弧可将抽气组件 10输送来 的外部空气击穿形成对等离子气流， 对等离子气流可从出气组件 50的出气端排 出形成等离子火焰， 进而可对厨具 40进行加热， 从而可取代燃气灶使用的气体 燃料， 可大大提高电加热装置的使用安全性； 通过将出气组件 50分别插装于第 一隔热件 20和第二隔热件 30上， 第一隔热件 20与第二隔热件 30间隔设置， 第一 隔热件 20和第二隔热件 30可有效将出气组件 50排出的高温等离子气流与外部空 气隔开， 高温等离子气流受外部空气的影响较小， 高温等离子气流的温度变化 较小， 因而可提高电加热装置的热效率。 再通过提供吸引件 32, 吸引件 32可提 供磁场， 并通过磁场力改变等离子气流的方向， 等离子气流朝向吸引件 32转向 使得可将高温的等离子气流汇集， 提高电加热装置的加热效率。 [0047] 进一步地， 如图 8所示， 在本实施例中， 第二隔热件 30的底板的中部设有固定 凹槽 （图中未示出） ， 吸引件 32包括支撑件 （图中未示出） 以及位于支撑件顶 部的顶部件 321， 支撑件的底部插接于固定凹槽内。 通过设置固定凹槽， 可起到 将吸引件 32固定的作用， 并将吸引件 32设置为由支撑件和顶部件 321形成， 支撑 件用于固定以及支撑顶部件 321， 顶部件 321的尺寸大于支撑件的尺寸， 顶部件 3 21的磁场便会较支撑件更强， 等离子气流汇集方向为顶部件 321处， 而不会出现 磁力过强导致等离子流正对吸引件 32, 使得吸引件 32被等离子流损坏， 可起到 延长吸引件 32的使用寿命的作用。
[0048] 进一步地， 如图 8所示， 在本实施例中， 顶部件 321为圆形结构， 支撑件的顶部 与顶部件 321的圆心处连接。 通过将顶部件 321设置为圆形， 可使得从多个出气 组件 50的出气端排出的等离子气流受到大小较均匀的磁场力， 且方向指向顶部 件 321， 使得可进一步提高电加热装置的加热效率。
[0049] 进一步地， 如图 6~8所示， 在本实施例中， 第一隔热件 20具有碗杯状的第一腔 室 23 , 第二隔热件 30具有碗杯状的第二腔室 31， 第一腔室 23与第二腔室 31为间 隔设置， 第一腔室 23的周边开设有多个用于支撑各出气组件 50—端的第一通孔 2 31， 第二腔室 31的周边对应开设有多个用于支撑对应出气组件 50另一端的第二 通孔 311， 固定凹槽设于第二腔室 31的底部。 具体地， 各出气组件 50插入第一腔 室 23的第一通孔 231中， 又继续插入第二腔室 31对应的第二通孔 311中。 此结构 ， 第一隔热件 20和第二隔热件 30起到双重隔热作用， 各出气组件 50喷出的高温 空气流汇聚于第二腔室 31中， 并从该第二腔室 31的开口端对厨具 40进行加热。 由于第二腔室 31与外部环境之间被第一隔热件 20和第二隔热件 30隔热阻挡， 使 得高温空气流受外部环境的影响较小， 电加热装置具有较高的热效率。
[0050] 进一步地， 在本实施例中， 固定凹槽 （图中未示出） 设于第二腔室 31的底部的 中部， 且支撑件与固定凹槽螺纹连接。 通过将支撑件与凹槽螺纹连接， 在吸引 件 32使用较长时间后损坏时， 可便于吸引件 32的安装更换， 可迅速根据需求更 换和合适的尺寸的吸引件 32。
[0051] 进一步地， 如图 8所示， 在本实施例中， 支撑件和顶部件 321均为电磁铁件， 且 固定凹槽内设有可与支撑件电性连接的电极 55接头， 电极 55接头与外部的电源 电性连接。 通过将支撑件和顶部件 321均为电磁铁件， 这样， 便可在电极 55接头 的作用下， 与外部的电源导通， 并可根据电源提供的电流大小改变磁场的强度 ， 使得可调整等离子气流的形态及流速， 便于用户使用。
[0052] 进一步地， 如图 3或图 5所示， 在本实施例中， 各出气组件 50还包括用于与抽气 组件 10连通的进风头 51、 套设于喷气管 52—端的盖板 53、 套设于喷气管 52另一 端的离子头和用于与离子头配合形成电弧以击穿空气的电极 55 , 进风头 51具有 用于容置电极 55的容置室 511， 盖板 53盖于容置室 511上， 喷气管 52与容置室 511 连通。
[0053] 进一步地， 如图 5所示， 在本实施例中， 各出气组件 50包括用于与抽气组件 10 连通的进风头 51、 用于将等离子气流排出的喷气管 52、 套设于喷气管 52—端的 盖板 53、 套设于喷气管 52另一端的离子头和用于与离子头配合形成电弧以击穿 空气的电极 55 , 进风头 51具有用于容置电极 55的容置室 511， 盖板 53盖于容置室 511上， 喷气管 52与容置室 511连通。 抽气组件 10将外部空气通过进风通道输送 至容置室 511， 电极 55与离子头配合产生电弧并击穿空气， 以形成等离子气流， 并经喷气管 52排出， 以对厨具 40进行加热。
[0054] 进一步地， 如图 6所示， 在本实施例中， 抽气组件 10包括用于储存空气的集气 室 11和用于将外部空气抽至集气室 11中的抽气件 12, 集气室 11上开设有多个排 气孔 111， 各进风头 51均与一排气孔 111连通。 集气室 11为中空的密封腔室， 抽 气件 12与集气室 11连通。 此处， 抽气件 12优选为鼓风机、 轴流风机、 气泵及风 扇中的任意一种。 集气室 11上均匀分布有多个排气孔 111， 各排气孔 111与对应 的进风通道连通， 进风通道与对应的容置室 511连通。 此结构， 抽气件 12将外部 空气抽至集气室 11内， 通过各排气孔 111均分至各出气组件 50的容置室 511中， 使得各出气组件 50的高温等离子气流均匀一致。 在其它实施例中， 抽气件 12也 可以为其它抽气的设备， 在此不作唯一限定。
[0055] 进一步地， 在本实施例中， 第二隔热件 30上方还架设有用于支撑厨具 40的支撑 架 60。
[0056] 如图 1所示， 本申请实施例还包括一种加热灶， 包括上述的电加热装置、 以及 用于安装电加热装置的灶体。 [0057] 本申请实施例的加热灶， 由于电加热装置的出气组件 50产生的电弧可将抽气组 件 10输送来的外部空气击穿形成对等离子气流， 对等离子气流可从出气组件 50 的出气端排出形成等离子火焰， 进而可对厨具 40进行加热， 再通过提供吸引件 3 2, 通过吸引件 32改变等离子气流的方向， 等离子气流朝向吸引件 32转向使得可 将高温的等离子气流汇集， 提高电加热装置的加热效率。
[0058] 以上仅为本申请的较佳实施例而已， 并不用以限制本申请， 凡在本申请的精神 和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本申请的保护范 围之内。
