Description

炉头及电焰灶
本申请要求于2019年07月26日在中国专利局提交的、申请号为201921200166.2、发明名称为“炉头及电焰灶”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电加热领域，尤其涉及一种炉头及电焰灶。
 背景技术
电焰灶原理是由高压产生电焰进行工作，具体为通过变压器为离子针提供高压进而在炉头的离子针处产生电焰，其内部具有较多的电子元器件。炉头内的离子针的顶部产生加热电焰，使得炉头具有较高的温度，会对炉头处及电焰灶其他部位的零部件产生影响而影响电焰灶整机性能。为了保证电焰灶的性能及提升使用寿命，需要及时将炉头处的热量向外散发。
 技术问题
本申请实施例的目的之一在于：提供一种炉头，旨在解决，需要及时将炉头处的热量向外散发的问题。
 技术解决方案
为解决上述技术问题，本申请实施例采用的技术方案是：
第一方面，提供了一种炉头，包括开设有容置槽的底座、与所述底座相连的离子针，以及与所述容置槽的槽口相连并封闭所述容置槽的隔离板；所述隔离板与所述容置槽的槽底之间的间隙形成有散热腔，所述底座开设有与所述散热腔相通的进风口及出风口；所述进风口处和/或所述出风口处设有散热风机。
在一个实施例中，当所述进风口处设有所述散热风机时，所述散热风机与所述进风口之间设有分流罩，所述分流罩具有分流入口、第一分流出口及第二分流出口；所述散热风机安装于所述分流入口；所述第一分流出口与所述分流入口相通并与所述进风口相通；所述第二分离出口与所述分流入口相通并与所述底座的底部平齐。
在一个实施例中，所述隔离板开设有让位孔，所述离子针贯穿所述让位孔并与所述容置槽的槽底相连。
在一个实施例中，所述离子针与所述让位孔的内壁之间设有密封环。
在一个实施例中，所述离子针上设有多个散热环，相邻所述散热环之间具有间隙，所述散热环位于所述容置槽内。
在一个实施例中，所述容置槽内设有挡板，所述挡板位于所述离子头与所述出风口之间，所述挡板与所述出风口之间形成有间隙。
在一个实施例中，所述隔离板与所述底座之间设有密封圈。
在一个实施例中，所述进风口及所述出风口均开设于所述容置槽的内侧壁。
在一个实施例中，所述分流罩还包括第三分流出口，所述第二分流出口位于所述第一分流出口与所述第三分流出口之间。
第二方面，提供了一种电焰灶，包括机箱及上述的炉头；所述第三分流出口与所述机箱内相通。
 有益效果
本申请实施例提供的炉头的有益效果在于：炉头工作产生电焰时，散热风机工作，外界的室温空气从进风口进入散热腔内，散热腔内的高温空气从出风口排出，因此炉头内的热量被排出的高温空气及时带走，避免了炉头温度急剧升高，保证电焰灶整机使用时的性能及使用寿命。且由于隔离板封闭了容置槽，因此散热风机工作产生的气流不会对离子头顶部的电焰产生影响，避免了电焰窜动而降低加热效率。

以下结合具体实施例对本申请的实现进行详细的描述。
如图1-图3所示，本申请实施例提出了一种炉头，包括开设有容置槽11的底座1、与底座1相连的离子针2，以及与容置槽11的槽口相连并封闭容置槽11的隔离板3；隔离板3与容置槽11的槽底之间的间隙形成有散热腔4，底座1开设有与散热腔4相通的进风口12及出风口13；进风口12处和/或出风口13处设有散热风机5。
在本申请的实施例中，炉头工作时，散热风机5工作，外界的室温空气从进风口12进入散热腔4内，散热腔4内的高温空气从出风口13排出，因此炉头内的热量被排出的高温空气及时带走，避免了炉头温度急剧升高，保证电焰灶整机使用时的性能及使用寿命。且由于隔离板3封闭了容置槽11，因此散热风机5工作产生的气流不会对离子头顶部的电焰产生影响，避免了电焰窜动而降低加热效率。散热风机5可单独安装于进风口12或出风口13，也可同时在进风口12及出风口13安装，以实现在进风口12、散热腔4及出风口13之间形成连通的风道为准。
进一步地，请参阅图1-图2，作为本申请提供的炉头的另一种具体实施方式，当进风口12处设有散热风机5时，散热风机5与进风口12之间设有分流罩6，分流罩6具有分流入口61、第一分流出口62及第二分流出口63；散热风机5安装于分流入口61；第一分流出口62与分流入口61相通并与进风口12相通；第二分离出口与分流入口61相通并与底座1的底部平齐。散热风机5产生的气流通过第一风流出口进入散热腔4内对底座1的内部也即炉头的内部进行散热，同时通过第二分流出口63向底座1的底部供应气流，也即底座1的表面进行散热，保证底座1内部及外表面的热量均能及时向外排出。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，隔离板3开设有让位孔31，离子针2贯穿让位孔31并与容置槽11的槽底相连。也即离子针2的顶部位于容置槽11的外部，因此隔离板3将散热风机5提供的气流与离子针2的顶部隔离，当电焰灶工作时离子针2顶部产生的电焰不会受到该气流的影响，避免电焰窜动而影响对锅等厨具的加热效果。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，离子针2与让位孔31的内壁之间设有密封环，避免散热风机5产生的气流从离子针2与让位孔31之间的间隙流动至离子针2的顶部。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，离子针2上设有多个散热环21，相邻散热环21之间具有间隙，散热环21位于容置槽11内。离子针2上的散热环21使得离子针2的散热面积增加，提升了对离子针2的散热效率，而离子针2为主要的发热部件，因此有效的提升了对炉头的散热效率。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，容置槽11内设有挡板14，挡板14位于离子头与出风口13之间，挡板14与出风口13之间形成有间隙。由于离子针2与产生高压的变压器电连接，并通过高压产生电焰，将挡板14设于离子头与出风口13之间，避免离子针2的高压对炉头外部产生影响。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，隔离板3与底座1之间设有密封圈7，以密封隔离板3与底座1之间的间隙，避免散热风机5产生的气流从该间隙处穿过而影响离子针2上的电焰。密封圈7可为硅胶圈或者硅胶固定后形成。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，进风口12及出风口13均开设于容置槽11的内侧壁。
进一步地，请参阅图2，作为本申请提供的炉头的另一种具体实施方式，分流罩6还包括第三分流出口64，第二分流出口63位于第一分流出口62与第三分流出口64之间。
本申请实施例提出了一种电焰灶，包括机箱及上述实施例中的炉头。当炉头具有分流罩6时，第三分流出口64与机箱内相通，也即实现了散热风机5对炉头散热的同时还对机箱内供应了散热气流。
可以理解的是，另一种具体实施方式中的方案可为在其他实施例的基础上进一步改进的可实现的实施方案。
显然，本申请的上述实施例仅仅是为了清楚说明本申请所作的举例，而并非是对本申请的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。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，均应包含在本申请权利要求的保护范围之内。
