上述微波炉中，由于导风罩包括文丘里效应腔体，风扇组件经送风口所吹出的气流可进入文丘里效应腔体，使文丘里效应腔体的出风口产生负压，进而可通过通气孔吸出腔体内部的气流。因此，腔体内部的污染物能被及时地排出，保证了微波炉的使用寿命。

请参阅图1，本发明较佳实施例的微波炉100包括腔体102、风扇组件104及导风罩106。
腔体102开设有与该腔本内部相通的通气孔108。请参图2，例如，通气孔108的数量是多个，多个通气孔108排列成矩形形状。每个通气孔108呈较易加工的圆柱形通孔。
风扇组件104设置在该腔体102上，该风扇组件104具有送风口110。
导风罩106设置在该腔体102侧边，请参图4，该导风罩106包括文丘里效应腔体112。请结合图3，该文丘里效应腔体112包括进风口114及出风口116，该进风口114与该送风口110相通，该出风口116与该通气孔108相通。
具体地，文丘里效应腔体112的进风口114较大，出风口116较小。风扇组件104经送风口110吹出的气流由较大的进风口114进入，由较小的出风口116吹出。
因此，在出风口116吹出的气流的流速比进风口114进入的气流的流速要大，出风口116附近产生负压，对出风口116附近的气流产生吸附作用。
进一步地，设置在腔体102侧边的文丘里效应腔体112与腔体102侧边形成更为密封 的通风管，进一步增强了文丘里效应。
该腔体102是用于放置被加热食物。微波炉100工作时，产生的微波被导入至腔体102内对被加热食物进行加热。加热时，被加热食物可能会释放出油烟及/或蒸汽等污染物。
在微波炉100工作的同时，一方面，风扇组件104可对微波炉100的电气件进行冷却。另一方面，风扇组件104的送风口110吹出的气流也可进入文丘里效应腔体112，使文丘里效应腔体112的出风口116产生负压，进而可通过通气孔108吸出腔体102内部的气流。
更进一步地，由于在加热食物的过程中，腔体102内的温度会升高，因此，腔体102内的气体会因温度升高而膨胀，进而通过通气孔108向腔体102外排出。也就是说，腔体102内的气体因腔体102内外的温差，自身也产生向腔体102外流动的趋势。
因此，腔体102内部的污染物在多重作用下能被及时地排出，不会停留或较少停留在腔体102内部，从而保证了微波炉100的使用寿命。
较佳地，在本实施例中，为了增强文丘里效应腔体112的出风口116的吸力，该导风罩106包括与该文丘里效应腔体112连接的吸气腔体118，该吸气腔体118罩设在该通气孔108上，该吸气腔体118连通该通气孔108及该出风口116。
请参图3及图4，具体地，吸气腔体118包括罩设在通气孔108上的进气部120及与出风口116连通的出气部122。
该进气部120呈长方体状，该出气部122呈沿进气部120向出风口116方向逐渐变小的漏斗状。因此，罩设在通气孔108上的进气部120能够最大限度地让腔体102内部的气流经通气孔108全部进入至导风罩106内，同时，呈漏斗状的出气部122也能增加从腔体102内向腔体102外的气流流速，更快地带出腔体102内部的油烟及/或蒸汽等污染物。
较佳地，在本实施例中，为了将导风罩106及腔体102内的气流导向微波炉100的底部出气口123，该导风罩106包括与该文丘里效应腔体112及该吸气腔体118连接的出气腔体124，该出气腔体124用于将气流导向该微波炉100的底部出气口123。
具体地，出气腔体124呈沿远离文丘里效应腔体112的方向逐渐变大的形状，出气腔体124的出气开口126朝向微波炉100的底部。因此，导风罩106及腔体102内的气流能够较快地被导向微波炉100的底部出气口123。
较佳地，在本实施例中，为了将导风罩106固定至腔体102侧边，该导风罩106包括第一固定部128，该第一固定部128设置在该文丘里效应腔体112的侧边。
该腔体102侧边设置有第二固定部130，该第二固定部130与该第一固定部128固接而将该导风罩106固定在该腔体102侧边。
具体地，在本实施例中，第二固定部130与第一固定部128通过螺合的方式固接，第 二固定部130与第一固定部128均开设有螺孔。
可以理解，在其它实施例中，第二固定部与第一固定部也可以通过焊接的方式固接，或通过卡合的方式固接等合适的方式。
另外，微波炉100的微波可由磁控管132产生，磁控管132由供电装置134供电。
具体地，磁控管132及供电装置134均设置该腔体102上，磁控管132电连接供电装置134，由供电装置134向磁控管132提供工作的电压。供电装置134可为变压器或变频器。
对应地，风扇组件104的送风口110包括第一子送风口136及第二子送风口138。该磁控管132位于该第一子送风口136的出风侧。该供电装置134位于该第二子送风口138与该进风口114之间，该第二子送风口138与该进风口114对应设置。
因此，在本实施例中，经第二子送风口138吹出的气流先经过供电装置134，对供电装置134冷却，之后再经进风口114进入导风罩106。
气流在经过供电装置134时，温度升高，温度升高后的气流再进入导风罩106，这使得进入导风罩106的气流流速更快，进而增强了文丘里效应，提高了吸出腔体102内的气流的吸力。
另外，该风扇组件104包括电机140、转动地设置在该电机140相背两侧的第一风扇(图未示)及第二风扇(图未示)。
该第一风扇与该第一子送风口136相对。该第二风扇与该第二子送风口138相对。
因此，分开设置的第一风扇与第二风扇可分别独立地对第一子送风口136及第二子送风口138吹风，相互不影响。
进一步地，为方便用户观察腔体102内被加热食物的状况，该微波炉100包括设置在该腔体102侧边的照明装置142，该照明装置142与该导风罩106间隔设置。
具体地，照明装置142包括炉灯144及反射罩146，炉灯144固定在反射罩146中，反射罩146固定在腔体102侧边。在一种示例中，反射罩146呈U型。
对应于炉灯144的腔体102侧边的位置设有透光部，炉灯144发光的光线能够通过透光部并进入腔体102内部，为用户提供照明。
在本实施例中，该微波炉100包括设置在该腔体102上的控制面板148，该控制面板148通过位于该控制面板148两端的支撑件150稳固在该腔体102上。控制面板148设置有控制按键及控制板，用户通过操作控制按键控制微波炉100的运行。
支撑件150的设置能够避免用户在操作控制面板148时，控制面板148晃动的问题。
具体地，该支撑件150包括第一端部152、第二端部154及连接该第一端部152与该 第二端部154的连接部156。
该第一端部152与该第二端部154相对于该连接部156倾斜设置。该第一端部152沿该连接部156延伸的方向与该第二端部154沿该连接部156延伸的方向相反。
本实施例中，第一端部152与控制面板148通过螺合的方式固接，第二端部154与腔体102通过螺合的方式固接。可以理解，在其它实施例中，第一端部152与控制面板148可通过卡合、铆接或焊接等其它方式固接，第二端部154与腔体102可通过卡合、铆接或焊接等其它方式固接。
综上所述，上述微波炉100中，由于导风罩106包括文丘里效应腔体112，风扇组件104经送风口110所吹出的气流可进入文丘里效应腔体112，使文丘里效应腔体112的出风口116产生负压，进而可通过通气孔108吸出腔体102内部的气流。因此，腔体102内部的油烟及/或蒸汽等污染物能被及时地排出，保证了微波炉100的使用寿命。
