本申请的说明书和权利要求书及上述附图中的术语“包括”以及它们任何变形，意图在于覆盖不排他的包含。例如包含一系列步骤或单元的过程、方法或系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
电焰灶包括升压装置、用于向所述升压装置供电的电源组件、利用所述升压装置产生的高压生成火焰的火焰发生装置1和用于驱动所述升压装置的控制器，升压装置将市电升压为万伏的高压，火焰发生装置1利用高压产生火焰，正常使用时，将锅具5放置在火焰发生装置1，火焰发生装置1产生的火焰对锅具5进行加热，但是当锅具5摆放不正确，例如锅具5和火焰发生装置1之间有间隙，万伏的高压有可能使用户造成触电。为了保证用户能够安全使用电焰灶，因此设计了一种具有检锅功能的电焰灶。
如图1所示，具有检锅功能的电焰灶，所述火焰发生装置1上安装有与所述控制器连接的检锅模块，所述检锅模块用于检测锅具5的状态以生成检锅信号，所述控制器根据所述检锅信号向所述升压装置发送驱动信号。
检锅模块可以检测锅具5的状态，判断锅具5是否按照规范要求放置，生成检锅信号传送至控制器，控制器根据检锅信号向升压装置发送驱动信号，控制升压装置工作或停止。当锅具5放置符合要求时，控制器控制升压装置输出高压，火焰发生装置1产生火焰，此时电焰灶正常工作；当锅具5放置不符合要求时，控制器控制升压装置停止工作，没有高压输出，电焰灶停止工作。通过此技术手段可以防止锅具5放置不规范，造成高压伤人的现象，提高装置使用的安全性。
如图2和图3所示，所述检锅模块包括第一信号采集器2、第二信号采集器3、第三信号采集器4和检锅单元，所述第一信号采集器2、所述第二信号采集器3和所述第三信号采集器4分布安装在所述火焰发生装置1上，所述第一信号采集器2连接所述检锅单元的第一输入端，所述第二信号采集器3连接所述检锅单元的第二输入端，所述第三信号采集器4接地，所述检锅单元的输出端连接所述控制器；当所述第一信号采集器2、所述第二信号采集器3和所述第三信号采集器4均与锅具5接触时，所述检锅单元输出第一信号，所述第一信号作为所述检锅信号；当所述第一信号采集器2、所述第二信号采集器3和所述第三信号采集器4中任意一个与锅具5不接触时，所述检锅单元输出第二信号，所述第二信号作为所述检锅信号。
当锅具5按照要求放置在火焰发生装置1上时，锅具5与第一信号采集器2、第二信号采集器3和第三信号采集器4均接触，由于锅具5为金属，因此第一信号采集器2、第二信号采集器3和第三信号采集器4相互导通，又因为第三信号采集器4接地，因此第一信号采集器2和第二信号采集器3采集的信号均为接地信号，检锅单元接收到第一信号采集器2的接地信号和第二信号采集器3的接地信号，输出检锅信号至控制器，此时检锅信号为第一信号，控制器根据第一信号控制升压装置工作，为火焰发生装置1提供需要的高压，此时电焰灶正常工作，为锅具5进行加热。
当锅具5没有按照要求放置在火焰发生装置1上，此时锅具5不能同时与三个信号采集器同时接触，因此造成第一信号采集器2和第二信号采集器3不能够同时接地，检锅单元也不能够同时接受到第一信号采集器2的接地信号和第二信号采集器3的接地信号，此时检锅单元输出的检锅信号为第二信号，控制器根据第二信号控制升压装置停止工作，停止输出高压，不会出现火焰发生装置1和锅具5之间放电的现象，避免用户触电的隐患，提高电焰灶使用的安全性。
作为一种可选的实施方式，所述第一信号采集器2、所述第二信号采集器3和所述第三信号采集器4互成120°。此设计能够实现三个信号采集器规则分布在火焰发生装置1，锅具5正常摆放时，能够与三个信号采集器均实现接触，当出现提锅或锅具5摆放不正确等情况时，锅具5不能够同时与三个信号采集器接触，通过此种手段实现对锅具5摆放是否符合规范的检测。
作为一种可选的实施方式，所述第一信号采集器2、所述第二信号采集器3和所述第三信号采集器4均为金属顶针。当锅具5放置在火焰发生装置1上时，金属顶针能够刺破锅具5的表面油污，实现良好的接触。
所述金属顶针位于所述火焰发生装置1上适配的凹槽内，所述金属顶针能够在所述凹槽内伸缩运动。火焰发生装置1上没有放置锅具5时，金属顶针伸出凹槽内，当将锅具5放置在火焰发生装置1上时，金属顶针受到锅具5的压力，收缩回凹槽中，不影响锅具5在火焰发生装置1的摆放。
作为一种可选的实施方式，所述检锅单元包括三点检锅电路和提锅检测电路；所述三点检锅电路，其第一输入端连接所述第一信号采集器2，其第二输入端连接所述第二信号采集器3，其输出端连接所述提锅检测电路的输入端，所述三点检锅电路用于根据所述第一信号采集器2和所述第二信号采集器3输入的信号，生成中间信号；所述提锅检测电路，其第一输出端连接所述控制器，用于根据所述中间信号，生成所述检锅信号。
当锅具5按照要求放置在火焰发生装置1上时，锅具5与第一信号采集器2、第二信号采集器3和第三信号采集器4均接触，由于锅具5为金属，因此第一信号采集器2、第二信号采集器3和第三信号采集器4相互导通，又因为第三信号采集器4接地，因此第一信号采集器2和第二信号采集器3采集的信号均为接地信号，三点检锅电路收到第一信号采集器2的接地信号和第二信号采集器3的接地信号，输出中间信号，提锅检测电路根据中间信号生成检锅信号，此时检锅信号为第一信号，控制器根据第一信号控制升压装置工作，为火焰发生装置1提供需要的高压，此时电焰灶正常工作，为锅具5进行加热。
当锅具5没有按照要求放置在火焰发生装置1上，此时锅具5不能同时与三个信号采集器同时接触，因此造成第一信号采集器2和第二信号采集器3不能够同时接地，三点检锅电路也不能够同时接受到第一信号采集器2的接地信号和第二信号采集器3的接地信号，输出中间信号，提锅检测电路根据中间信号生成检锅信号，此时检锅信号为第二信号，控制器根据第二信号控制升压装置停止工作，停止输出高压，不会出现火焰发生装置1和锅具5之间放电的现象，避免用户触电的隐患，提高电焰灶使用的安全性。
如图4所示，所述三点检锅电路包括第一继电器U1、第二继电器U2、第一二极管D1、第二二极管D2、第三二极管D3和第四二极管D4；
所述第一继电器U1，其线圈的正极分别连接所述第一二极管D1的阴极和所述第二二极管D2的阴极，其线圈的负极分别连接所述第一信号采集器2和所述第二二极管D2的阳极，其公共端连接所述第二继电器U2的公共端，其常闭触点悬空，其常开触点接地；
所述第二继电器U2，其线圈的正极分别连接所述第三二极管D3的阴极和所述第四二极管D4的阴极，其线圈的负极分别连接所述第二信号采集器3和所述第四二极管D4的阳极，其常闭触点悬空，其常开触点连接所述提锅检测电路的输入端；
所述第一二极管D1的阳极和所述第三二极管D3的阳极均连接继电器电源，继电器电源为12V电源。
第一二极管D1和第三二极管D3起到防浪涌的作用，第二二极管D2和第四二极管D4作用为继电器续流。
当锅具5按照要求放置在火焰发生装置1上时，锅具5与第一信号采集器2、第二信号采集器3和第三信号采集器4均接触，第一信号采集器2和第二信号采集器3均接地，第一继电器U1线圈的负极和第二继电器U2线圈的负极均接地，因此第一继电器U1和第二继电器U2均得电吸合，第一继电器U1的公共端和常开触点接触，第二继电器U2的公共端和常开触点接触，第二继电器U2的常开触点通过第一继电器U1公共端、第二继电器U2公共端和第一继电器U1常开触点接地，因此第二继电器U2的常开触点输出低电平。
当锅具5没有按照要求放置在火焰发生装置1上，此时锅具5不能同时与三个信号采集器同时接触，因此造成第一信号采集器2和第二信号采集器3不能够同时接地，第一继电器U1和第二继电器U2不能同时得电吸合，因此第二继电器U2的常开触点没有输出。
作为一种可选的实施方式，所述三点检锅电路还包括第一旁路电容电路Z1和第二旁路电容电路Z2；
所述第一旁路电容电路Z1，包括N个串联的电容，其一端接地，其另一端连接所述第一信号采集器2，其中，N为大于1的整数；
所述第二旁路电容电路Z2，包括M个串联的电容，其一端接地，其另一端连接所述第二信号采集器3，其中，M为大于1的整数。
第一旁路电容电路Z1和第二旁路电容电路Z2均为多个电容串联组成，能够防止因个别电容失效造成旁路电容电路失效的情况，增强电路的稳定性。
如图5所示，所述提锅检测电路包括光耦U3、第一电阻R1、第二电阻R2、第三电阻R3、第四电阻R4和第一电容C1；
所述第一电阻R1，其一端连接所述光耦U3的正输入端，其另一端分别连接所述三点检锅电路的输出端和电源板控制开关的一端；
所述光耦U3，其负输入端分别连接地和所述电源板控制开关的另一端，其第一输出端接地，其第二输出端连接所述第二电阻R2的一端，所述电源板控制开关的一端带有高电平；
所述第二电阻R2，其另一端分别连接所述第三电阻R3的一端、所述第四电阻R4的一端、所述第一电容C1的一端和所述控制器；
所述第四电阻R4的另一端和所述第一电容C1的另一端均接地，所述第三电阻R3的另一端连接直流电源。
当锅具5按照要求放置在火焰发生装置1上时，三点检锅电路输出低电平，此时光耦U3的两个输出端均为低电平，此时光耦U3的第一输出端和第二输出端不导通，第二电阻R2另一端输出高电平至控制器，控制器控制升压装置工作，为火焰发生装置1提供需要的高压，此时电焰灶正常工作，为锅具5进行加热。此时，电源板控制开关两端分别为高电平和低电平，因此电源板控制开关闭合，电源正常供电，电焰灶正常工作，为锅具5进行加热。
当锅具5没有按照要求放置在火焰发生装置1上，三点检锅电路没有输出，光耦U3的正输入端连接的电源板控制开关带有高电平，因此光耦U3导通，光耦U3的第一输出端和第二输出端导通，第二电阻R2的另一端输出低电平至控制器，控制器控制升压装置停止工作，停止输出高压，不会出现火焰发生装置1和锅具5之间放电的现象，避免用户触电的隐患，提高电焰灶使用的安全性。此时，电源板控制开关两端均为低电平，因此电源板控制开关两端断开，和电源断开，停止供电。
