[0046] 在本申请中， 除非另有明确的规定和限定， 术语“安装”、 “相连”、 “连接”、 “固 定”等术语应做广义理解， 例如， 可以是固定连接， 也可以是可拆卸连接， 或成 一体； 可以是机械连接， 也可以是电连接； 可以是直接相连， 也可以通过中间 媒介间接相连， 可以是两个元件内部的连通或两个元件的相互作用关系。 对于 本领域的普通技术人员而言， 可以根据具体情况理解上述术语在本申请中的具 体含义。
[0047] 如图 1~9所示， 本申请实施例提供一种电加热装置， 电加热装置包括用于产生 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 流进行隔热的隔热部 （图中未示出） ， 隔热部内形成有密闭的隔热腔 （图中未 示出） ， 隔热腔内完全填充设有隔热体 （图中未示出） ， 出气组件 50插接于隔 热部上， 抽气组件 10与出气组件 50连通， 隔热部开设有贯穿隔热部的顶部与底 部的排气管道。
[0048] 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插装于隔热部 上， 隔热部内形成有密闭的隔热腔， 隔热腔内完全填充设有隔热体， 隔热部可 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， 将空气间隔高温等 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。 再通过在隔热部上开设排气管道， 便可通过排气管道 将等离子气流燃尽后的废气排出， 并通过与排气管道连接的外部废气处理装置 回收废气， 避免废气从电加热装置泄露。
[0049] 进一步地， 如图 9所示， 在本实施例中， 过滤结构 70包括过滤挡板 71， 过滤挡 板 71间开设有容纳腔 711， 容纳腔 711内设有过滤海绵 72， 过滤海绵 72与容纳腔 7 11过盈配合。 通过设置过滤挡板 71， 使得过滤结构 70具有一定的强度， 再通过 在过滤挡板 71内开设容纳腔 711， 可将用于过滤有害气体的过滤海绵 72固定于容 纳腔 711内， 使得在使用过程中过滤结构 70的稳定性较高， 保障过滤结构 70的使 用寿命。
[0050] 进一步地， 如图 9所示， 在本实施例中， 过滤结构 70内开设有多个并排设置的 容纳腔 711， 多个容纳腔 711等间距间隔设置。 通过设置多个容纳腔 711以固定多 个过滤海绵 72, 使得过过滤结构 70的过滤和净化效果更佳。
[0051] 进一步地， 如图 9所示， 在本实施例中， 过滤海绵 72内部吸附有活性炭。 活性 炭可将有害气体和杂质吸附于活性炭上， 使得对废气的过滤与净化效果更佳。
[0052] 进一步地， 如图 2〜 8所示， 在本实施例中， 隔热部包括第一隔热件 20与位于第 一隔热件 20顶部的第二隔热件 30, 第一隔热件 20与第二隔热件 30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， 第一隔热件 20上开设有第一排气孔 24, 第二隔热件 30上开设有第二排 气孔 32, 第一排气孔 24与第二排气孔 32连通形成排气管道， 过滤结构 70设置于 排气管道内并靠近第一排气孔 24处。 具体地， 第一隔热件 20与第二隔热件 30可 拆卸固定， 这样， 便可通过将第一隔热件 20与第二隔热件 30拆卸开进行维检或 清洗， 并可更换设置于隔热腔内的隔热体。 由于等离子气流具有较高的温度， 因此， 将过滤结构 70设置于排气管道内并靠近第一排气孔 24处， 可待废气在隔 热部内降温后再与过滤结构 70接触， 避免因高温损坏， 使得隔热部的使用寿命 更长。
[0053] 进一步地， 如图 2~8所示， 在本实施例中， 隔热部包括第一隔热件 20与位于第 一隔热件 20顶部的第二隔热件 30, 第一隔热件 20与第二隔热件 30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， 第一隔热件 20上开设有第一排气孔 24, 第二隔热件 30上开设有第二排 气孔 32, 第一排气孔 24与第二排气孔 32连通形成排气管道。 具体地， 第一隔热 件 20与第二隔热件 30可拆卸固定， 这样， 便可通过将第一隔热件 20与第二隔热 件 30拆卸开进行维检或清洗， 并可更换设置于隔热腔内的隔热体。
[0054] 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， 第二隔热件 30封盖第一腔室 23形成隔热腔， 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 231， 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。 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***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
[0055] 进一步地， 在本实施例中， 隔热体内开设有排气通路， 排气通路 （图中未示出 ） 具有相对且相互连通的排气入口 （图中未示出） 与排气出口 （图中未示出）
， 排气入口与第二排气孔 32相互连通， 排气出口与第一排气孔 24连通。 在空气 被击穿形成等离子气流燃烧后， 会形成氮氧化物等的废气， 废气先从第二排气 孔 32进入隔热体， 并经由排气通路以及第一排气孔 24将废气排出至外部的废气 收集装置， 起到废气回收的作用。
[0056] 进一步地， 如图 7或图 8所示， 在本实施例中， 第二隔热件 30上开设有多个第二 排气孔 32, 多个第二排气孔 32均设于第二腔室 31的内壁上， 且多个第二排气孔 3 2的高度一致。 在点加热装置工作时， 会持续的产生废气， 且可通过调节出气组 件 50的功率， 使得击穿空气形成等离子气流的速率上升， 导致废气增多甚至废 气淤积， 通过设置多个排气孔 111， 可有效提高通过排气管道排废气的速率。
[0057] 进一步地， 如图 7或图 8所示， 在本实施例中， 多个第二排气孔 32均匀等间距间 隔设置。 通过将排气孔 111等间距设置， 可起到将排气管道从第二腔室 31内的废 气均匀排出的作用， 避免因排气不均匀导致的第二腔室 31会形成定向的流向排 气管道的气流， 导致电加热装置对厨具 40的加热不均匀， 起到使得厨具 40的锅 体被均匀加热的作用。
[0058] 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。
[0059] 进一步地， 如图 4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， 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 件与集气室 11连通。 此处， 抽气件优选为轴流风机、 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， 抽气件也可以为其它抽气的设 备， 在此不作唯一限定。
[0060] 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。
[0061] 如图 1所示， 本申请实施例还提供一种加热灶， 包括上述的电加热装置， 还包 括用于安装电加热装置的灶体。
[0062] 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， 再通过在隔热部上 开设排气管道， 便可通过排气管道将等离子气流燃尽后的废气排出， 并通过与 排气管道连接的外部废气处理装置回收废气， 避免废气从电加热装置泄露。
[0063] 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。
