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容装槽及盖体处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电磁发生模块、散热片和散热风机组装 后的示意性结构图。
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。
特别地，箱体10的顶部开设有开口向上的容装槽12。容装槽12可由箱体10的顶表面10a向下凹陷形成。容装槽12的开口处覆盖有一盖体13，以在容装槽12和盖体13之间限定出一容装空间14，盖体13上开设有用于连通容装空间14和箱体10所处外部环境的散热孔。电磁发生模块21设置于容装空间14内，容装空间14内还设有散热风机31，用于驱动气流通过散热孔在容装空间14和箱体10所处外部环境之间流动，从而对电磁发生模块21进行散热。
由于电磁加热装置的电磁发生模块21设置在箱体10顶部的容装槽12和盖体13形成的容装空间14内，即电磁发生模块21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，由于功率较大的电磁发生模块21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， 盖体13上设置散热孔，电磁发生模块21产生的热量可通过散热孔散热出去。进一步地，容装空间14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，促使电磁发生模块21产生的热量更加快速地散发至外部环境空间，从而对电磁发生模块21进行快速、有效地降温，提高了加热效率和加热效果、延长其使用寿命。
图3和图4是根据本发明一个实施例的容装槽及盖体处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。图5是根据本发明一个实施例的电磁发生模块、散热片和散热风机组装后的示意性结构图，图5中的曲线箭头表示气流流进散热风机31的方向。参见图1至图5，在一些实施例中，盖体13包括顶壁131和由顶壁131的周缘向下延伸的周壁132。顶壁131可向上凸出于箱体10的顶表面10a，即顶壁131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132的第一侧壁上的多个进风孔133和开设在周壁132的与其第一侧壁相对设置的第二侧壁上的多个出风孔134，以允许散热风机31驱动的气流由进风孔133进入容装空间14，并经出风孔134流出，从而对电磁发生模块21进行强制对流散热。也就是说，可将进风孔133和出风孔134设置在盖体13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，进一步提高了电磁发生模块21的散热效率。
在一些实施例中，容装空间14内还设有多个散热片32，用于对电磁发生模块21进行辅助散热。散热片32的设置可增大电磁发生模块21的散热面积，从而进一步提高电磁发生模块21的散热效率和散热效果。
进一步地，多个散热片32并排且间隔地设置在电磁发生模块21的表面，从而直接与电磁发生模块21热连接，提高了热量自电磁发生模块21至散热片32的热传递效率。多个散热片32的并排方向设置成使得相邻两个散热片32之间的间隙与气流在容装空间14内的流向相吻合，以使得气流流经每相邻两个散热片32之间的间隙后经出风孔134流出。由此，一方面可减小散热片32给气流流动带来的阻力作用，提高气流流速，另一方面，还可保证气流与散热片32的充分接触，从而保证气流带走更多的热量。
具体地，气流在容装空间14内的流向为由进风孔133流向出风孔134。相邻两个散热片32之间的间隙沿由进风孔133指向出风孔134的方向贯通，多个散热片32的并排方向垂直于由进风孔133指向出风孔134的方向。
在一些实施例中，散热风机31和多个散热片32均设置在电磁发生模块 21的上表面，散热风机31位于散热片32的邻近进风孔133的一侧，散热风机31的出风口朝向多个散热片32，以便于促使外界气流流向散热片32。
在一些实施例中，散热风机31的数量为两个，两个散热风机31沿多个散热片32的并排方向并排设置，以确保气流均匀地流过多个散热片32。在一些替代性实施例中，散热风机31的数量还可以为一个或三个以上。
在一些实施例中，盖体13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135，以防止外界的水进入容装空间14内。盖体13本身的设置可以在一定程度上避免电磁发生模块21被水淋或粘灰等，盖体13内还特别地设计有挡水筋135，挡水筋135处于盖体周壁的内侧，因此，可避免箱体10顶部的水浸入容装空间14中造成电磁发生模块21受潮或落灰，甚至造成不必要的安全隐患。具体地，挡水筋135可向下延伸至与箱体10的顶表面10a抵接或向下延伸至与容装槽12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135环绕在电磁发生模块21的四周，也就是说，挡水筋135具有四个依次相连的筋板，以防止水从电磁发生模块21的任一侧进入。挡水筋135的分别与周壁的第一侧壁和第二侧壁相对的筋板上均开设有通孔1351，以允许气流流过，从而确保挡水筋135的设置不会影响气流的正常流动。
在一些实施例中，其中一个储物间室11中放置有具有筒体41和门体42的储物装置40，加热腔室形成在储物装置40中。在进行加热处理时，门体42封闭筒体41，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41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通过预置在箱体10的发泡层中的导线50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。
具体地，信号处理及测控电路23具有从储物装置40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211和第二信号传输接口212，第一射频端口231与第二射频端口211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212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41可具有便于取放物品的取放开口，门体42可包括具有导电性能 的端板，在门体42关闭时，端板封闭筒体41的取放开口，从而封闭筒体41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42处于封闭筒体41的取放开口的关闭状态时与筒体41电性连接，以在门体42处于关闭状态时使得筒体41和门体42形成连续导电的屏蔽体。由此，可确保筒体41与门体42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41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。

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。
