具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开实施例的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种微波炉的结构方框图，在本实施例中，微波炉可以是具有微波加热功能的微波炉，也可以是兼具微波加热和光波加热功能的光波炉，还可以是集成有微波加热功能的其它家电设备。
如图1所示，该微波炉包括：箱体1，箱体1包括加热舱2，设置在箱体1中的主控板3，主控板3是配置为控制微波炉的各部件进行正常工作的部件。设置在加热舱2中的磁场产生组件4和磁场感应组件5，当磁场产生组件4产生的磁场产生变化时，磁场感应组件5能采集到磁场的变化情况。磁场感应组件5与主控板3电性相连。
可选地，磁场产生组件4设置在加热舱2的入口位置。
可选地，磁场产生组件4为永磁体或与主控板3相连的线圈。也即，磁场产生组件4可以是永磁体，永磁体能够产生磁场。当金属物体进入加热舱2时会切割磁感线，引起磁场变化。磁场产生组件4还可以是与主控板3相连的线圈。线圈里面的电流会在线圈周围产生磁场，当金属物体进入加热舱2时会切割磁感线，引起磁场变化。
可选地，磁场感应组件5设置在加热舱2的入口位置。比如，磁场产生组件4设置在加热舱2的入口下方位置，磁场感应组件5设置在加热舱2的入口上方位置。
磁场感应组件5设置在加热舱2的入口位置，当金属物体经过入口时， 会切割磁感线，磁场感应组件5会采集到磁场变化信号。
可选地，磁场感应组件5是磁阻传感器。磁场感应组件5为一个，或者，磁场感应组件5包括按照规则阵列或者不规则阵列排布的多个。
通常，磁场感应组件5为一个时，即可检测到是否有金属物体进入加热舱，当磁场感应组件5为多个时，主控板3能够根据多个磁场感应组件5采集到的磁场变化情况分析出金属物体的形状及大小。
当磁场感应组件5是磁阻传感器时，磁阻传感器配置为采集磁场产生组件4产生的磁场的磁场变化信号，该磁场变化信号能够表征金属物体的速度(速度方向和速度大小)，并将磁场变化信号发送给主控板3；主控板3配置为根据磁场变化信号检测是否存在金属物体进入加热舱2；在存在金属物体进入加热舱2时，控制加热舱2不进行工作。换句话说，当存在金属物体进入加热舱2时，主控板3对用户触发的加热指令不进行响应，不控制加热舱2进行工作。
可选地，微波炉还包括与主控板3相连的无线通信组件6。可选地，无线通信组件6安装在电源线的插头中。
无线通信组件6包括：WIFI网络组件、蓝牙组件或zigbee组件中的至少一种。
可选地，微波炉还包括与主控板3相连的显示屏7。
显示屏7配置为在磁场感应组件5检测到金属物体进入加热舱2时，在主控板3的控制下显示告警提示。该告警提示用于提示用户取出金属物体。
综上所述，本公开实施例中提供的微波炉，通过包括箱体，箱体包括加热舱，设置在箱体中的主控板，设置在加热舱中的磁场产生组件和磁场感应组件，磁场感应组件与主控板电性相连；解决了目前的微波炉不能检测到进入加热舱的金属物品，用户误将金属物品放入微波炉进行加热时， 容易引起安全隐患的问题；达到了微波炉能够检测出金属物品，并在检测到金属物品进入加热舱时将加热舱停止工作，从而消除了由于对金属物品进行微波加热造成的安全隐患的效果。
图2是根据一示例性实施例示出的一种微波炉控制方法的流程图，如图2所示，本实施例以该微波炉控制方法应用于图1所示的微波炉中举例说明，该微波炉控制方法包括以下步骤。
在步骤202中，通过磁场感应组件采集磁场产生组件产生的磁场的磁场变化信号。
在步骤204中，通过主控板根据磁场变化信号检测是否存在金属物体进入加热舱。
在步骤206中，在存在金属物体进入加热舱时，通过主控板控制加热舱不进行工作。
在主控板判断存在金属物体进入加热舱时，主控板不对用户的输入的操作指令进行响应，不控制加热舱进行工作。
在金属物体被移出加热舱时，由于金属物体移动的方向与进入加热舱时的方向相反，磁阻传感器感应到的磁场变化信号中的方向特性与金属物体进入加热舱时的磁场变化信号中的方向特性相反。所以主控板通过磁场变化信号中的方向特性来识别金属物体是进入加热舱还是移出加热舱。
综上所述，本公开实施例中提供的微波炉控制方法，通过磁场感应组件采集磁场产生组件产生的磁场的磁场变化信号，通过主控板根据磁场变化信号检测是否存在金属物体进入加热舱，在存在金属物体进入加热舱时，通过主控板控制加热舱不进行工作；解决了目前的微波炉不能检测到进入加热舱的金属物品，用户误将金属物品放入微波炉进行加热时，容易引起安全隐患的问题；达到了微波炉能够检测出金属物品，并在检测到金属物品进入加热舱时将加热舱停止工作，从而消除了由于对金属物品进行微波 加热造成的安全隐患的效果。
图3是根据另一示例性实施例示出的一种微波炉控制方法的流程图，如图3所示，本实施例以该微波炉控制方法应用于图1所示的微波炉中举例说明，该微波炉控制方法包括以下步骤。
在步骤302中，通过磁场感应组件采集磁场产生组件产生的磁场的磁场变化信号。
磁场产生组件会在加热舱内产生磁场，当金属物体进入加热舱时会切割磁感线，引起磁场变化。磁场感应组件采集磁场产生组件产生的磁场的磁场变化信号。
在步骤304中，通过主控板根据磁场变化信号检测是否存在金属物体进入加热舱。
磁阻传感器将采集到的磁场变化信号发送给主控板，主控板检测接收到的的磁场变化信号来判断是否存在金属物体进入加热舱。当磁场变化信号的磁场强度逐渐增大或逐渐减小时，则判定存在金属物体进入加热舱；当没有接收到磁场变化信号时，则判定不存在金属物体进入加热舱。
在步骤305中，在不存在金属物体进入加热舱时，通过主控板控制加热舱进行工作。
在步骤306中，在存在金属物体进入加热舱时，通过主控板控制加热舱不进行工作。
在主控板判定存在金属物体进入加热舱时，主控板不对用户输入的操作指令进行响应，不控制加热舱进行工作。可选地，主控板缓存用户输入的操作指令。
在步骤308中，在存在金属物体进入加热舱时，通过主控板控制无线通信组件向移动终端发送告警提示，告警提示用于提示用户取出金属物体。
如图4所示，主控板通过控制无线通信组件向移动终端的应用程序发 送告警提示，提示用户取出金属物体。
可选地，如图5所示，步骤308还可被替换为步骤308A，在存在金属物体进入加热舱时，通过主控板控制显示屏显示告警提示，告警提示用于提示用户取出金属物体。当然也可通过亮灯或者蜂鸣来告警提示用户取出金属物体。
显示屏上显示的告警提示如图6所示，也可以为其它约定形式。本实施例对此不作具体限定。
可选地，如图7所示步骤308之后还可以包括：
在步骤310中，在存在金属物体进入加热舱时，通过主控板控制显示屏显示告警提示，告警提示用于提示用户取出金属物体。
即在存在金属物体进入加热舱时，通过主控板同时控制无线通信组件向移动终端发送告警提示和控制显示屏显示告警提示。
可选地，如图8所示步骤310之后还可以包括步骤312、步骤313和步骤314。
在步骤312中，通过主控板检测是否存在金属物体移出加热舱。
在步骤313中，在没有检测到金属物体移出加热舱时，通过主控板控制加热舱不进行工作。
在步骤314中，在检测到金属物体移出加热舱时，通过主控板控制加热舱进行工作。
可选地，主控板检测是否存在金属物体移出加热舱的方法，包括：在微波炉箱体外壳上设置复位按钮，当检测到用户按下此按钮后即判定为检测到金属物体移出加热舱。
可选地，主控板检测是否存在金属物体移出加热舱的方法，包括：在金属物体被移出加热舱时，由于金属物体移动的方向与进入加热舱时的方向相反，磁阻传感器感应到的磁场强度变化方向与金属物体进入时的磁场 强度变化方向相反，因此当磁阻传感器感应到的磁场强度变化方向与金属物体进入时的磁场强度变化方向相反时，磁阻传感器判定为检测到金属物体移出加热舱。当主控板检测到金属物体已经移出后，主控板根据已经保存的用户操作指令来控制微波炉的加热舱进行工作。
综上所述，本公开实施例中提供的微波炉控制方法，通过磁场感应组件采集磁场产生组件产生的磁场的磁场变化信号，通过主控板根据磁场变化信号检测是否存在金属物体进入加热舱，在存在金属物体进入加热舱时，通过主控板控制加热舱不进行工作；解决了目前微波炉不能检测进入加热舱的金属物品，用户误将金属物品放入微波炉进行加热时，容易引起安全隐患的问题；达到了微波炉检测金属物品，在检测到金属物品时停止工作，并提示用户取出金属物品，消除了由于对金属物品进行微波加热造成的安全隐患的效果。
本领域技术人员在考虑说明书及实践这里公开的发明后，将容易想到本公开实施例的其它实施方案。本申请旨在涵盖本公开实施例的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开实施例的一般性原理并包括本公开实施例未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开实施例的真正范围和精神由下面的权利要求指出。
应当理解的是，本公开实施例并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本公开实施例的范围仅由所附的权利要求来限制。
