具体实施方式
图1是根据本发明一个实施例的加热单元100的示意性结构图；图2是图1所示加热单元100的示意性剖视图，其中电磁发生模块161和供电模块 162被去除。参见图1和图2，加热单元100可包括筒体110、门体120、和电磁发生系统。
筒体110可用于放置待处理物，且其前壁或顶壁可开设有取放口，用于取放待处理物。
门体120可通过适当方法与筒体110安装在一起，例如滑轨连接、铰接等，用于开闭取放口。在图示实施例中，加热单元100还包括用于承载待处理物的抽屉140，抽屉140的前端板设置为与门体120固定连接，两个横向侧板通过滑轨与筒体110活动连接。抽屉140与门体120可为注塑形成的一体件，也可预组装为一体件。
电磁发生系统可设置为至少一部分设置于筒体110内或通达至筒体110内，以在筒体110内产生电磁波来加热筒体110内的待处理物。
筒体110和门体120可分别设置有电磁屏蔽特征，使门体120在关闭状态时与筒体110导电连接，以防止电磁泄露。
在一些实施例中，电磁发生系统可包括电磁发生模块161、供电模块162、和辐射天线150。
供电模块162可设置为与电磁发生模块161电连接，以为电磁发生模块161提供电能，进而使电磁发生模块161产生电磁波信号。辐射天线150可设置于筒体110内并与电磁发生模块161电连接，以根据电磁波信号产生相应频率的电磁波，对筒体110内的待处理物进行加热。
在一些实施例中，筒体110可由金属制成，以作为接收极接收辐射天线150产生的电磁波。在另一些实施例中，筒体110与辐射天线150相对的侧壁可设置有接收极板，以接收辐射天线150产生的电磁波。
图4是本发明一个实施例的电器室112的示意性结构图；图6是本发明另一个实施例的电器室112的示意性结构图。参见图4和图6，辐射天线150的周缘可由平滑曲线构成，以筒体110内电磁波的分布更加均匀，进而提高待处理物的温度均匀性。其中，平滑曲线指曲线方程为一阶导数连续的曲线。在工程中意味着辐射天线150的周缘无尖角。
参见图2和图4，加热单元100还可包括罩壳130，以将筒体110的内部空间分隔为加热室111和电器室112。待处理物和辐射天线150可分别设置于加热室111和电器室112，以将待处理物和辐射天线150分隔开，防止辐射天线150脏污或误触损坏。
在一些实施例中，罩壳130可由绝缘材料制成，以使辐射天线150产生的电磁波可穿过罩壳130加热待处理物。进一步地，罩壳130可由半透明或不透明的PP材料制成，以减少电磁波在罩壳130处的电磁损耗，进而提高对待处理物的加热速率。
罩壳130还可用于固定辐射天线150，以简化加热单元100的装配流程、便于辐射天线150的定位安装。具体地，罩壳130可包括分隔加热室111和电器室112的隔板131、以及与筒体110内壁固定连接的裙部132。其中，辐射天线150可设置为与隔板131固定连接。

辐射天线150可设置于筒体110的1/3～1/2高度处，例如1/3、2/5或1/2，以使加热室111的容积较大的同时，使加热室111内的电磁波具有较高的能量密度，进而使待处理物被快速地加热。
图3是图2中区域A的示意性放大视图。参见图1至图3，电磁发生系统还可包括信号处理及测控电路170。具体地，信号处理及测控电路170可包括检测单元171、控制单元172、和匹配单元173。
检测单元171可串联在电磁发生模块161与辐射天线150之间，并配置 为实时检测经过其的入射波信号和反射波信号的特定参数。
控制单元172可配置为从检测单元171获取该特定参数，根据该特定参数计算入射波和反射波的功率。在本发明中，特定参数可为电压值和/或电流值。检测单元171也可为功率计，以直接测得入射波和反射波的功率。
控制单元172可进一步根据入射波和反射波的功率计算待处理物的电磁波吸收率，并将电磁波吸收率与预设吸收阈值比较，当电磁波吸收率小于预设吸收阈值时向匹配单元173发送调节指令。预设吸收阈值可为60～80％，例如60％、70％、或80％。
匹配单元173可串联在电磁发生模块161与辐射天线150之间，并配置为根据控制单元172的调节指令对电磁发生模块161的负载阻抗进行调节，提高电磁发生模块161的输出阻抗和负载阻抗的匹配度，以在加热室111内放置有固定属性(种类、重量、体积等)不同的食物、或食物在温度变化过程中均有较多的电磁波能量被辐射在加热室111内，进而提高加热速率。
罩壳130与筒体110对应匹配单元173的位置处可分别开设有散热孔，以使匹配单元173工作时产生的热量经散热孔排出。
在一些实施例中，加热单元100可用于解冻。控制单元172还可配置为根据入射波和反射波的功率计算待处理物的介电系数的虚部变化率，并将虚部变化率与预设变化阈值比较，当待处理物介电系数的虚部变化率大于等于预设变化阈值时向电磁发生模块161发送停止指令，使电磁发生模块161停止工作，解冻程序终止。
预设变化阈值可通过测试不同固定属性的食物在-3～0℃时的介电系数的虚部变化率获得，以使食物具有较好的剪切强度。例如当待处理物为生牛肉时，预设变化阈值可设置为2。
在一些实施例中，信号处理及测控电路170可集成于一块电路板，并与辐射天线150平行设置，以便于辐射天线150与匹配模块的电连接。
在一些实施例中，信号处理及测控电路170可设置于辐射天线150的后侧。散热孔可开设于罩壳130和筒体110的后壁。罩壳130的后部可设置为向上凸起，以在其下方形成扩大空间。

控制单元172可设置为与门体检测装置190电连接以接收门体检测装置190的电信号并根据该电信号判断门体120的开闭状态，并配置为在确定门体120处于打开状态时向电磁发生模块161发生停止工作的指令，使电磁发生模块161停止产生电磁波信号，以防止电磁波泄露。
在一些实施例中，门体检测装置190可为行程开关，固定于筒体110的后部，并配置为在门体120处于关闭状态时被抽屉140的后壁触发，控制单元172在行程开关被触发时确定门体120处于关闭状态。
门体检测装置190可固定于罩壳130向上凸起的部分的前壁，以便于门体检测装置190与控制单元172的电连接。
在一些实施例中，金属筒体110可设置为接地，以将其上的电荷导出，提高加热单元100的安全性。
加热单元100还可包括金属支架180。金属支架180可设置为连接电路板与筒体110，以支撑电路板并将电路板上的电荷经由筒体110导出。在一些实施例中，金属支架180可由互相垂直的两部分组成。
