具体实施方式
本实施例首先提供了一种冰箱，图1是根据本发明一个实施例的冰箱的示意框图，该冰箱包括：识别模块10、气体检测模块20、除味模块30以及主控模块40。
识别模块10识别冰箱内部的食物。气体检测模块20检测冰箱内部挥发性有机化合物的浓度值。除味模块30对冰箱内部进行除味操作。主控模块40预先设置包含多种食物的食物列表，判断冰箱内部的食物种类是否存在于食物列表中，并在冰箱内部的食物种类存在于食物列表中时，开启除味模块30对冰箱进行除味操作，在冰箱内部的食物种类均不存在于食物列表中时，根据浓度值的大小，调整除味模块30的工作强度，多种食物包括能够产生挥 发性有机化合物的食物。
主控模块40预先制定并存储一份食物列表，该食物列表中的食物均为在未变质时就能够散发异味或是腐烂气味的食物，比如：榴莲、发酵食物等。这些食物即便没有变质也能够产生异味，污染冰箱内部空气。在检测到冰箱内部的食物含有上述食物列表中的某一种食物时，主控模块40开启除味模块30对冰箱进行除味操作，以防止腐烂气味堆积。
在主控模块40确定冰箱内部不存在食物列表上的食物时，气体检测模块20开启对冰箱内部气体进行检测，气体检测模块20主要用于检测挥发性有机化合物(VOC)，当食物发生变质或腐烂时，会产生大量的VOC气体。气体检测模块20通过检测VOC气体的浓度值来确定食物的腐烂程度，从而设定除味模块30的工作强度，保证将冰箱内部异味除尽。
图2是根据本发明另一个实施例的冰箱的示意框图。在本实施例中，识别模块10包括：摄像模块11、图像识别模块12以及射频识别模块13。摄像模块11设置于冰箱间室内，配置成拍摄冰箱内部的图像。图像识别模块12利用图像对冰箱内部食物进行识别。射频识别模块13利用无线射频识别带有电子标签的食物。
上述摄像模块11可以为摄像机，设置于冰箱间室内部顶部，以全面拍摄间室内部图象。图像识别模块12对拍摄的图像进行识别，以确定冰箱内部食物种类，在一些可选的实施例中，图像识别模块12还可以将图像上传至云服务器，通过网络对图像进行识别。
射频识别模块13可以为RFID读写器。射频识别RFID(Radio Frequency Identification)技术是一种通信技术，可通过无线电讯号识别特定目标并读写相关数据，而无需识别系统与特定目标之间建立机械或光学接触。其最重要的优点是非接触识别，它能穿透雪、雾、冰、涂料、尘垢和条形码无法使用的恶劣环境阅读标签，并且阅读速度极快，大多数情况下不到100毫秒。因此，在智能冰箱中RFID技术具有巨大的应用前景，且能对冰箱的智能化带来无法预知的巨大空间。
在冰箱领域，可通过在冰箱上配置RFID电子标签，以实现在生产、运输、使用过程中对冰箱的管控；还可在冰箱上配置RFID读写器，在存储食物上配置电子标签，实现冰箱对食物的智能管理。存储食物上配置的电子标签可以包含食物的名称、种类、生产日期、保质期、重量等各种食物的基本信息。RFID读写器通过读取电子标签上的食物种类识别食物。
识别模块10将图像识别和射频识别的识别结果进行汇总得到最终识别结果。例如：利用图像识别出冰箱内部包括A、B、C三种食物，利用射频识别出冰箱内部包括A、B、D三种食物，最终汇总后的识别结果为，冰箱内部包括A至D四种食物。由于摄像头未必能够拍摄到冰箱内的全景图像，因此一些食物(如：位于冰箱死角内的食物或是被其他食物遮 挡的食物)不能被识别，同时，并不是所有食物都带有电子标签，因此利用无线射频识别也可能造成识别的遗漏，将两种识别进行结合，提高了识别的准确度。
在本实施例中。除味模块30包括设置于冰箱内部的风扇，风扇将冰箱内部的空气排出至冰箱外部。本实施例中的除味模块30利用风扇排风对冰箱内部进行除味操作，风扇产生的风速越快，其除味能力越强。
主控模块40在冰箱内部的食物种类存在于食物列表中的情况下，开启风扇，以第一转速运转预设时间。若上述识别结果中存在食物列表中的食物，例如识别出榴莲或是某种发酵类食物，风扇以第一转速开启排风，上述第一转速可以为风扇能够允许达到的最高转速。
在本实施例中，主控模块40当浓度值处于第一数值区段内时，控制风扇以第一转速运转预设时间；当浓度值处于第二数值区段内，控制风扇以第二转速运转预设时间；当浓度值处于第三数值区段内，控制风扇以第三转速运转预设时间；当浓度值处于第四数值区段内，控制风扇停止运转；其中第一数值区段、第二数值区段、第三数值区段和第四数值区段的数值大小依次递减，第一转速、第二转速和第三转速产生的风速大小依次递减。
在本实施例中，检测到VOC气体浓度越高，风扇转速越快以便快速清除冰箱内部的异味气体。上述第一数值区段可以为2000ppm以上，第二数值区段可以为1000～2000ppm，上述第三数值区段可以为500～1000ppm以上，第四数值区段可以为0～500ppm。例如，在本实施例中，风扇具有三个可调节转速，当VOC气体浓度在2000ppm以上时，证明冰箱内部腐烂气体浓度非常高，此时，控制风扇以顶级转速工作，当VOC气体浓度在1000ppm～2000ppm时，冰箱内部腐烂气体浓度较高，此时，控制风扇以中级转速工作，当VOC气体浓度在500ppm～1000ppm时，冰箱内部腐烂气体浓度为中等水平，此时，控制风扇以低级转速工作，当VOC气体浓度在500ppm以下时，冰箱内部腐烂气体浓度在合理范围内，此时，控制风扇停止转动以节省电能。上述预设时间可以根据冰箱内VOC气体浓度下降速度进行设定。
识别模块10还配置成在控制风扇运转预设时间后，重新识别冰箱内部的食物，以重新确定当前冰箱内的食物以及VOC气体浓度。
本实施例还提供了一种冰箱的控制方法，图3是根据本发明一个实施例的冰箱的控制方法的示意图，其包括：
步骤S302，设置包含多种食物的食物列表，多种食物包括能够产生挥发性有机化合物的食物。主控模块40预先制定并存储一份食物列表，该食物列表中的食物均为在未变质时就能够散发异味或是腐烂气味的食物，比如：榴莲、发酵食物等。这些食物即便没有变质也能够产生异味，污染冰箱内部空气。
步骤S304，识别冰箱内部的食物。
步骤S306，判断冰箱内部的食物种类是否存在于食物列表中。
步骤S308，若步骤S306的判断结果为是，开启冰箱的除味模块30对冰箱进行除味操作。在检测到冰箱内部的食物含有上述食物列表中的某一种食物时，主控模块40开启除味模块30对冰箱进行除味操作，以防止腐烂气味堆积。
步骤S310，如果步骤S306的判断结果为否，检测冰箱内部挥发性有机化合物的浓度值，并根据浓度值的大小，调整除味模块30的工作强度。在主控模块40确定冰箱内部不存在食物列表上的食物时，气体检测模块20开启对冰箱内部气体进行检测，气体检测模块20主要用于检测挥发性有机化合物(VOC)的浓度，当食物发生变质或腐烂时，会产生大量的VOC气体。气体检测模块20通过检测VOC气体的浓度值来确定食物的腐烂程度，从而设定除味模块30的工作强度，保证将冰箱内部异味除尽。

步骤S404，拍摄冰箱内部的图像，利用图像识别冰箱内部的食物。在本实施例中，可以通过设置于冰箱间室内部顶部的摄像机，全面拍摄间室内部图象。然后对拍摄的图像进行识别，以确定冰箱内部食物种类，在一些可选的实施例中，还可以将图像上传至云服务器，通过网络对图像进行识别。
步骤S406，利用无线射频识别冰箱内部的食物。在本实施例中，可以通过设置于冰箱上的RFID读写器读取电子标签上的信息从而识别食物种类。
步骤S408，将两种识别方式的识别结果进行汇总得到最终识别结果。例如：利用图像识别出冰箱内部包括A、B、C三种食物，利用射频识别出冰箱内部包括A、B、D三种食物，最终汇总后的识别结果为，冰箱内部包括A至D四种食物。由于摄像头未必能够拍摄到冰箱内的全景图像，因此一些食物(如：位于冰箱死角内的食物或是被其他食物遮挡的食物)不能被识别，同时，并不是所有食物都带有电子标签，因此利用无线射频识别也可能造成识别的遗漏，将两种识别进行结合，提高了识别的准确度。
步骤S410，判断冰箱内部的食物种类存在于食物列表中。
步骤S412，若步骤S410的判断结果为是，开启除味模块30的风扇，以第一转速运转预设时间。若上述识别结果中存在食物列表中的食物，例如识别出榴莲或是某种发酵类食物，风扇以第一转速开启排风，以防止腐烂气味堆积，上述第一转速可以为风扇能够允许达到的 最高转速。
步骤S414，若步骤S410的判断结果为否，判断冰箱内部挥发性有机化合物的浓度值是否处于第一数值区段内，上述第一数值区段可以为2000ppm以上。
步骤S416，若步骤S414的判断结果为是，控制风扇以第一转速运转预设时间。例如，在本实施例中，风扇具有三个可调节转速，当VOC气体浓度在2000ppm以上时，证明冰箱内部腐烂气体浓度非常高，此时，控制风扇以顶级转速工作，上述预设时间可以根据冰箱内VOC气体浓度下降速度进行设定。
步骤S418，若步骤S414的判断结果为否，判断冰箱内部挥发性有机化合物的浓度值是否处于第二数值区段内，第二数值区段可以为1000～2000ppm。
步骤S420，若步骤S418的判断结果为是，控制风扇以第二转速运转预设时间。当VOC气体浓度在1000ppm～2000ppm时，冰箱内部腐烂气体浓度较高，此时，控制风扇以中级转速工作。
步骤S422，如果步骤S418的判断结果为否，判断浓度值是否处于第三数值区段内。上述第三数值区段可以为500～1000ppm以上。
步骤S424，如果步骤S422的判断结果为是，控制风扇以第三转速运转预设时间。当VOC气体浓度在500ppm～1000ppm时，冰箱内部腐烂气体浓度为中等水平，此时，控制风扇以低级转速工作。
步骤S424，控制风扇停止运转。如果步骤S422的判断结果为否，浓度值位于第四数值区段(0～500ppm)。VOC气体浓度在500ppm以下时，冰箱内部腐烂气体浓度在合理范围内，此时，控制风扇停止转动以节省电能。
本实施例提供了一种冰箱的控制方法，其包括：预先设置包含多种食物的食物列表，识别冰箱内部的食物，判断冰箱内部的食物种类是否存在于食物列表中，若是，开启冰箱的除味模块30对冰箱进行除味操作；若否，检测冰箱内部挥发性有机化合物的浓度值，并根据浓度值的大小，调整除味模块30的工作强度。本实施例的冰箱预先制定并存储一份食物列表，该食物列表中的食物均为在未变质时就能够散发异味或是腐烂气味的食物，比如：榴莲、发酵食物等。这些食物即便没有变质也能够产生异味，污染冰箱内部空气。在检测到冰箱内部的食物含有上述食物列表中的某一种食物时，主控模块40开启除味模块30对冰箱进行除味操作，清除冰箱内部的异味以防止腐烂气味堆积。
进一步地，本实施例的冰箱的控制方法当浓度值处于第一数值区段内，控制风扇以第一转速运转预设时间，当浓度值处于第二数值区段内，控制风扇以第二转速运转预设时间，当 浓度值处于第三数值区段内，控制风扇以第三转速运转预设时间，当浓度值处于第四数值区段内，控制风扇停止运转。本实施例的冰箱的控制方法检测冰箱内部挥发性有机化合物的浓度值，并根据浓度值的大小，调整除味模块30的工作强度，使得冰箱内挥发性有机化合物的浓度值始终处于正常范围值内，同时优化了冰箱的除味操作。
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。
