本发明的冷藏冷冻装置具有电磁加热装置，其利用电磁波对待处理物进行加热、解冻等，加热效率高、加热均匀且可保证食物品质。特别地，用于为电磁发生模块供电的供电模块设置在箱体上方的供电盒内，即供电模块位于箱体的外部，不会占用箱体内的储物空间和加热腔室内的加热空间，储物空间及加热空间都比较大，空间利用率较高。
同时，由于供电模块处于箱体外的顶部，其产生的热量不会散发在箱体内而影响储物间室内的储藏温度。更为重要的是，供电盒的盒体上设置散热孔，供电盒内还设有散热风机，可通过散热风机驱动气流流动，促使供电模块产生的热量散发至外部环境空间，从而对供电模块进行快速、有效地降温，杜绝了供电模块连续工作时温度升高导致的寿命及效率的下降，同时杜绝用户无意触摸引起的灼伤隐患。

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的冷藏冷冻装置的示意性结构图；
图2是根据本发明一个实施例的冷藏冷冻装置的示意性剖视图；
图3和图4是根据本发明一个实施例的供电盒处结构的不同方位的示意性剖视图；
图5是根据本发明一个实施例的供电盒的下底壳的示意性结构图。
具体实施方式
本发明提供一种冷藏冷冻装置，该冷藏冷冻装置可以为冰箱、冰柜或其他具有冷藏和/或冷冻功能的储物装置。图1是根据本发明一个实施例的冷藏 冷冻装置的示意性结构图，图2是根据本发明一个实施例的冷藏冷冻装置的示意性剖视图。
参见图1至图2，本发明的冷藏冷冻装置1包括箱体10，箱体10内限定有至少一个储物间室11。进一步地，冷藏冷冻装置1还可以包括门体，用于打开和/或关闭储物间室11。其中一个储物间室11中限定有一用于容纳待处理物的加热腔室，该加热腔室可以对待处理物进行加热、解冻等。具体地，箱体10内可限定有多个储物间室11，例如可包括冷藏间室、冷冻间室和变温间室，以上各个间室的温度互不相同，因此功能各异。加热腔室可形成在冷藏间室、冷冻间室和变温间室中的任一个间室中。
进一步地，冷藏冷冻装置1还包括电磁加热装置，其用于向加热腔室内提供电磁波，以对加热腔室内的待处理物进行加热。电磁加热装置提供的电磁波可以为射频波、微波等具有合适波长的电磁波。这种利用电磁波对待处理物进行加热的方式加热效率高、加热均匀且可保证食物品质。电磁加热装置通常具有用于产生电磁波信号的电磁发生模块21和用于为电磁发生模块21提供电源的供电模块24。由于电磁发生模块21和供电模块24的功率都比较大，产生的热量较多，因此可将电磁发生模块21和供电模块24设置于箱体10的发泡层的外侧，以避免对箱体10内的储物环境造成影响，同时也便于热量的散发。电磁发生模块21例如可设置于箱体10的顶部外侧、背部外侧或者压缩机仓19内等等。
特别地，箱体10的顶部上方设有一供电盒40，供电盒40的盒体上开设有用于连通供电盒40内部和供电盒40所处外部环境的散热孔。供电模块24设置于供电盒40内，供电盒40内还设有散热风机31，用于驱动气流通过上述散热孔在供电盒40内部和供电盒40所处外部环境之间流动，从而对供电模块24进行散热。
用于为电磁发生模块21供电的供电模块24设置在箱体10上方的供电盒40内，即供电模块24位于箱体10的外部，不会占用箱体10内的储物空间和加热腔室内的加热空间，储物空间及加热空间都比较大，空间利用率较高。
同时，由于供电模块24处于箱体10外的顶部，其产生的热量不会散发在箱体10内而影响储物间室内的储藏温度。更为重要的是，供电盒40的盒体上设置散热孔，供电盒40内还设有散热风机31，可通过散热风机31驱动 气流加快流动，促使供电模块产生的热量更加快速地散发至外部环境空间，从而对供电模块24进行快速、有效地降温，杜绝了供电模块24连续工作时温度升高导致的寿命及效率的下降，同时杜绝用户无意触摸引起的灼伤隐患。
图3和图4是根据本发明一个实施例的供电盒处结构的不同方位的示意性剖视图，图3和图4所沿的剖切线相互垂直。参见图1至图4，供电盒40包括设置于箱体10的顶表面的下底壳41和覆盖在下底壳41上方的上盒体42。供电模块24和散热风机31均设置于下底壳41上。也就是说，供电模块24和散热风机31均支撑在下底壳41上，上盒体42从上往下地覆盖在供电模块24、散热风机31和下底壳41上。
在一些实施例中，上盒体42包括顶壁421和由顶壁421的周缘向下延伸的周壁422。顶壁421可向上凸出于箱体10的顶表面10a，即顶壁421高于箱体10的顶表面10a，既不会占用空间，又能够很好地散热。上述散热孔包括开设在周壁422的第一侧壁上的多个进风孔43和开设在周壁422的与其第一侧壁相对设置的第二侧壁上的多个出风孔44，以允许散热风机31驱动的气流由进风孔43进入供电盒40内，并经出风孔44流出，从而对供电模块24进行强制对流散热。也就是说，可将进风孔43和出风孔44设置在上盒体42的两个相对的侧壁上，便于气流形成对流效果，从而增大气流的流速，进一步提高了供电模块24的散热效率。
在一些实施例中，散热风机31可位于供电模块24的邻近出风孔44的一侧，散热风机31的进风口朝向供电模块24，以便于促使气流更加快速地从进风孔43流进供电盒40内，并更加快速地从出风孔44流出，提高了气流的流速。
进一步地，散热风机31可为轴流风机。在另一些实施例中，散热风机31还可以为其他类型的风机，例如离心风机、贯流风机等等，只要布置好散热风机在供电盒40内的风路，使其出风口朝向供电模块24即可。
进一步地，散热风机31的数量为一个、两个或三个以上。
在一些实施例中，上盒体42还包括由其顶壁向下延伸，并相邻地位于其周壁内侧的挡水筋45，以防止外界的水进入供电盒40内。供电盒40本身的设置可以在一定程度上避免供电模块24被水淋或粘灰等，供电盒40内还特别地设计有挡水筋45，挡水筋45处于上盒体42周壁的内侧，因此，可避 免箱体10顶部的水浸入容装空间14中造成供电模块24受潮或落灰，甚至造成不必要的安全隐患。具体地，挡水筋45可向下延伸至与下底壳41的底壁抵接，以更好地起到防水的作用。
在一些实施例中，挡水筋45环绕在供电模块24的四周，也就是说，挡水筋45具有四个依次相连的筋板，以防止水从供电模块24的任一侧进入。挡水筋45的分别与周壁422的第一侧壁和第二侧壁相对的筋板上均开设有通孔451，以允许气流流过，从而确保挡水筋45的设置不会影响气流的正常流动。
图5是根据本发明一个实施例的供电盒的下底壳的示意性结构图。参见图5，供电模块24可包括用于集成电源处理电路的PCB电路板241，PCB电路板241上设有用于与供电电源相连的输入端子242和用于与电磁发生模块21相连的输出端子243，以通过PCB电路板241上的电源处理电路将经输入端子242输入的电源电压处理后经输出端子243输出给电磁发生模块21。具体地，输入端子242和输出端子243可分别位于PCB电路板241的相对的两个端部。
在一些实施例中，其中一个储物间室11中放置有具有筒体61和门体62的储物装置60，加热腔室形成在储物装置60中。在进行加热处理时，门体62封闭筒体61，从而形成封闭的加热腔室，避免电磁泄漏。
进一步地，电磁加热装置还包括设置于筒体61中的辐射天线22和信号处理及测控电路23，辐射天线22与信号处理及测控电路23电连接，电磁发生模块21与信号处理及测控电路23电连接，进而与辐射天线22电连接。
更进一步地，电磁发生模块21可设置于箱体10的发泡层的外侧，电磁发生模块21可通过预置在箱体10的发泡层中的导线50与信号处理与测控电路23电连接。具体地，电磁发生模块21可设置于压缩机仓19内。电磁发生模块21与供电模块24之间通过预置在箱体10的发泡层中的电源线相连。
具体地，信号处理及测控电路23具有从储物装置60的后壁上引出的第一射频端口231和第一信号传输接口232，电磁发生模块21具有第二射频端口和第二信号传输接口，第一射频端口231与第二射频端口之间通过预置在箱体10的发泡层中的射频线缆相连，第一信号传输接口232与第二信号传输接口之间通过预置在箱体10的发泡层中的信号传输线缆相连。
筒体61可具有便于取放物品的取放开口，门体62可包括具有导电性能的端板，在门体62关闭时，端板封闭筒体61的取放开口，从而封闭筒体61内的加热腔室。端板可以为由导电金属材料制成的金属端板，也可以为由其他导电材料制成的导电端板。门体41还包括与端板电连接的至少一个导电连接件。导电连接件配置成至少在门体62处于封闭筒体61的取放开口的关闭状态时与筒体61电性连接，以在门体62处于关闭状态时使得筒体61和门体62形成连续导电的屏蔽体。由此，可确保筒体61与门体62之间形成稳定的电连接，从而在加热时形成连续导电的屏蔽体，阻止了电磁波经该间隙射出，有效地屏蔽了电磁辐射、消除了电磁辐射对人体的伤害。筒体61可以为金属筒体，也可以为在其上设置例如可以为导电涂层、导电金属网等的电磁屏蔽特征的非金属筒体。
本领域技术人员应理解，在没有特殊说明的情况下，本发明实施例中所称的“顶”、“底”、“内”、“外”、“横”、“前”、“后”等用于表示方位或位置关系的用语是以冷藏冷冻装置1的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或部件必须具有特定的方位，因此不能理解为对本发明的限制。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
