如图1所示，本申请实施例的烹饪器具可包括底座10、器具本体20和称重装置30，称重装置30用于对器具本体20进行称重，以获取放入器具本体20中的待烹饪食物重量信息。
其中，器具本体20适于搁置在底座10上且相对底座10可分离。底座10可直接连接到市电电源，而器具本体20不直接连接到市电电源。当器具本体20被搁置在底座10上时，底座10可为该器具本体20提供烹饪电源或烹饪热源。具体地，底座10上的加热装置可通过无线供电或端子供电等方式为搁置在底座10上的器具本体20提供烹饪电源，也可通过加热盘加热、微波辐射加热或电磁辐射加热等方式为搁置在底座10上的器具本体20提供烹饪热源。
另外，底座10上可适于分别搁置多个不同类型的器具本体20，通过同一底座10与不同类型的器具本体20配合工作，可组成不同的烹饪器具。其中，不同类型的器具本体20对应不同的烹饪功能。举例而言，具有压力装置的器具本体20与底座10可以组成分体式 电压力锅；具有煮饭装置的器具本体20与底座10可以组成分体式电饭煲等。这样可利用一个底座实现多种不同的烹饪功能，从而能够减少对厨房空间的占用。
为了获取器具本体20的重量信息，且不占用底座的空间，可在器具本体20上设置称重装置30，且在本申请的一个实施例中，称重装置30可包括重量传感器31，例如，可以是光电式重量传感器、电磁力式重量传感器、电容式重量传感器、电阻应变式重量传感器等，具体类别可以根据实际需要进行选择。如图2所示，重量传感器31可为多个，且重量传感器31可对应器具本体20的底部设置。
如图3所示，当器具本体20与底座10构成完整烹饪器具时(即当用户将器具本体20对应放置在底座10上时)，称重装置30可通过重量传感器31对器具本体20进行称重，因此，能够有效地避免对底座进行称重，能够使得称重装置的称重量程减少，从而能够提高称重的精确度。
如图3所示，器具本体20的底部可设有支撑位，重量传感器31对应支撑位设置。其中，支撑位可为四个，四个支撑位分别对应器具本体20的底部四个角设置，重量传感器31可为四个，四个重量传感器31一一对应四个支撑位设置，这样能够使得每个重量传感器31所获得的器具本体20的重量信息基本一致，由此，能够提高称重的精确度。
需要说明的是，上述实施例仅作为本申请的一个具体实施例，还可以通过其他方式实现对器具本体20的称重，具体这里不在赘述。
图4是根据本申请实施例的烹饪器具的保温性能自动调节方法的流程图。如图4所示，本申请实施例的烹饪器具的保温性能自动调节方法，包括以下步骤：
S1，当烹饪器具进入保温状态时，通过称重装置获取器具本体内米饭的初始重量，并对烹饪器具进行开合盖检测以判断烹饪器具在保温过程中是否进行开盖操作。
具体而言，在烹饪器具上电后，烹饪器具进入待机状态，此时用户根据自身需求选择煮米饭功能，在用户选择后，可以提醒用户需要加的米量，并按照提示加入相应的米量和水，然后在用户选择开始按键后，烹饪器具进入开始煮饭。通常在烹饪器具完成煮米饭后，会自动进入保温状态。在烹饪器具进入保温状态后，有可能出现两种情况，一种是在保温的过程中，用户正在用餐，此时需要不停的打开和关闭烹饪器具的上盖，即一段时间内出现频繁打开和关闭烹饪器具上盖的情况；另一种是在保温的过程中，在上下两餐的间隔时间内，用户一直没有打开烹饪器具的上盖，即一段时间内一直未出现打开和关闭烹饪器具上盖的情况。而对于这两种情况，为了使得保温后的米饭的效果就像刚煮好一样，需要使用不同的保温方法。
具体地，当烹饪器具进入保温状态时，通过称重装置获取器具本体内米饭的初始重量， 记为m1，并对烹饪器具进行开合盖检测以判断烹饪器具在保温过程中是否进行开盖操作，其中可以采用现有技术来判断烹饪器具的上盖是否被打开。如果在一段时间(如1小时)内烹饪器具的上盖被打开，则执行与上述第一种情况相对应的开盖保温调节方法；否则，执行与上述第二种情况相对应的未开盖保温调节方法。
S2，如果烹饪器具在保温过程中进行开盖操作，则通过称重装置实时获取器具本体内米饭的实际重量，并判断当前实际重量是否大于初始重量。
S3，如果当前实际重量大于初始重量，则在烹饪器具内的温度达到预设的参考保温温度时控制烹饪器具的上盖保温目标温度减小和烹饪器具的上盖加热功率减小，并控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变。
具体而言，在烹饪器具进行保温的过程中，还可以对保温情况做进一步划分，例如，对于第一种情况，在用户用餐的过程中，除了需要不停的打开和关闭烹饪器具的上盖，以从器具本体内盛出米饭的情况，还有可能存在将冷米饭放入器具本体内的情况，即，针对第一种情况，器具本体内的米饭量有可能增加(如，放入冷饭到器具本体内，以在下一餐时吃)，也有可能减少(如，用餐时往外盛饭)。而对于这两种情况，又可以采用不同的保温方法，以使保温后的米饭更加可口。
具体地，如果烹饪器具的上盖在保温的过程被打开，并且通过称重装置实时获取的器具本体内米饭的实际重量m2大于初始重量m1，则先不做任何调节，而是按照正常保温过程来使器具本体内的温度达到预设的参考保温温度(如，现有技术中所达到的保温温度)。然后，当器具本体内的温度达到预设的参考保温温度后，将烹饪器具的上盖保温目标温度减小，并将烹饪器具的上盖加热功率减小，以免米饭表面发干、发黄，同时控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，即维持底部保温温度即可。
进一步地，根据本申请的一个实施例，当烹饪器具在保温过程中进行开盖操作时，如果当前实际重量小于初始重量，则控制烹饪器具的上盖保温目标温度增大和烹饪器具的上盖加热功率增大，并控制烹饪器具的底部加热功率减小，以及控制烹饪器具的底部保温目标温度保持不变。
具体而言，如果烹饪器具的上盖在保温的过程被打开，并且通过称重装置实时获取的器具本体内米饭的实际重量m2小于初始重量m1，则将烹饪器具的上盖保温目标温度增大，并将烹饪器具的上盖加热功率增大，同时控制烹饪器具的底部加热功率减小，以及控制烹饪器具的底部保温目标温度保持不变，这样可以保证上下两端的温差最小，避免冷凝水的产生。
进一步地，图5给出了烹饪器具在保温过程中进行开盖操作时的保温性能自动调节方法的逻辑过程，如图5所示，开盖操作时的保温性能自动调节方法可包括以下步骤：
S101，开始保温。
S102，通过称重装置获取开始保温时器具本体内的米饭的重量，记录为初始重量m1。
S103，通过称重装置持续获取器具本体内的米饭的重量，记录为实际重量m2。
S104，判断是否存在m2＞m1。如果是，执行步骤S105；如果否，执行步骤S108。
S105，先按照正常保温过程来使器具本体内的温度达到参考保温温度。
S106，在达到参考保温温度后，将上盖保温目标温度减小。
S107，将上盖加热功率减小。
S108，判断是否存在m2＜m1。如果是，执行步骤S109；如果否，执行步骤S112。
S109，上盖保温目标温度增大。
S110，上盖加热功率增大。
S111，底部加热功率减小。
S112，判断最近一次开盖时间是否大于1小时。如果是，执行步骤S113；如果否，返回步骤S103。
S113，进入未开盖保温过程。
根据本申请的一个实施例，当烹饪器具在保温过程中无开盖操作时，通过称重装置实时获取器具本体内米饭的实际重量，并获取初始重量与当前实际重量的差值，以及判断初始重量与当前实际重量的差值是否大于第一预设阈值，其中，如果初始重量与当前实际重量的差值大于第一预设阈值，则控制烹饪器具的底部保温目标温度减小和烹饪器具的底部加热功率减小，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变；如果初始重量与当前实际重量的差值小于等于第一预设阈值，则控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变。
具体而言，对于上述的第二种情况，在保温的过程中，如果用户一直没有打开烹饪器具的上盖，则器具本体内一直在循环水分蒸发、上盖冷凝，最终蒸发水回流到器具本体内这样一个过程。而对于其中的水分蒸发和上盖冷凝是两种不同的物理变化过程，所以还可以对这两种情况做进一步区分，即采用不同的保温方法。
具体地，当烹饪器具在保温的过程中无开盖操作时，通过称重装置实时获取器具本体内米饭的实际重量，记为m2，并获取初始重量m1与当前实际重量m2的差值，以及判断初始重量m1与当前实际重量m2的差值是否大于第一预设阈值n1(n1可根据整个加热系统预先调节，一般取2～4小时的保温蒸发量)。如果初始重量m1与当前实际重量m2的差值大于第一预设阈值n1，则将烹饪器具的底部保温目标温度减小，并将烹饪器具的底部加热功率减小，以减少器具本体内的水分蒸发量，同时控制烹饪器具的上盖保温目标温度和 烹饪器具的上盖加热功率保持不变；否则，控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变，即维持正常保温过程，不做调节。
进一步地，根据本申请的一个实施例，在控制烹饪器具的底部保温目标温度减小和烹饪器具的底部加热功率减小、以及控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变之后，还获取器具本体内米饭的实际重量变化值，并判断器具本体内米饭的实际重量变化值是否大于第二预设阈值，其中，如果器具本体内米饭的实际重量变化值大于第二预设阈值，则控制烹饪器具的底部保温目标温度增大和烹饪器具的底部加热功率增大，并控制烹饪器具的上盖加热功率增大，以及控制烹饪器具的上盖保温目标温度保持不变；如果器具本体内米饭的实际重量变化值小于等于第二预设阈值，则控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变。
具体而言，在控制烹饪器具的底部保温目标温度减小和烹饪器具的底部加热功率减小、以及控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变之后，通过称重装置实时获取器具本体内米饭的实际重量，记为m3，并计算器具本体内米饭的实际重量变化值即m3-m2，并判断实际重量变化值m3-m2是否大于第二预设阈值n2(n2的取值可为2～4小时内的回流水的重量，具体可根据实际滴白情况进行调整)。如果实际重量变化值m3-m2大于第二预设阈值n2，则将烹饪器具的上盖加热功率增大(如果有侧面加热，还可以适当增大侧面加热功率)，以达到快速蒸发冷凝水的效果，同时将烹饪器具的底部保温目标温度增大，并将烹饪器具的底部加热功率增大，以及控制烹饪器具的上盖保温目标温度保持不变；否则，控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变，即维持正常保温过程，不做调节。
进一步地，图6给出了烹饪器具在保温过程中未进行开盖操作时的保温性能自动调节方法的逻辑过程，如图6所示，未开盖操作时的保温性能自动调节方法可包括以下步骤：
S201，开始保温。
S202，通过称重装置获取开始保温时器具本体内的米饭的重量，记录为初始重量m1。
S203，通过称重装置持续获取器具本体内的米饭的重量，记录为实际重量m2。
S204，判断是否存在m1-m2＞n1。如果是，执行步骤S205；如果否，执行步骤S207。
S205，底部加热功率减小。
S206，底部目标温度减小。
S207，维持正常保温过程，不做调节。
S208，通过称重装置持续获取器具本体内的米饭的重量，记录为实际重量m3。
S209，判断是否存在m3-m2＞n2。如果是，执行步骤S210；如果否，执行步骤S213。
S210，上盖加热功率增大。
S211，底部目标温度增大。
S212，底部加热功率增大，有侧面调功的，侧面加热功率增大。
S213，维持正常保温过程，不做调节。
综上，本申请实施例的烹饪器具的保温性能自动调节方法，在保温的过程中，通过结合器具本体内米饭的重量来对保温温度和功率进行调节，使得米饭保温性能更加精确，有效避免了米饭表面发干、发黄以及表面白的情况，使得米饭的效果就像刚煮好一样，具有较高的使用价值。
在实际应用中，当用户使用烹饪器具煮饭时，经常会多煮一些用于保温或其他用途，也就是经常会有剩饭，而剩饭不及时处理就容易变质或口感变差，给用户带来不好的影响。为此，在本申请的一个实施例中，在烹饪器具完成烹饪进入保温状态后，根据实时获取的器具本体内米饭的实际重量判断器具本体内是否存在剩余米饭；如果器具本体内存在剩余米饭且持续时间达到第一预设时间，则控制烹饪器具发出剩饭提示信息。
其中，根据实时获取的器具本体内米饭的实际重量判断器具本体内是否存在剩余米饭，包括：根据实时获取的米饭的实际重量获取器具本体内的米饭重量变化情况；根据米饭重量变化情况判断器具本体内的米饭的实际重量在第二预设时间内维持不变且大于等于预设重量时，判断器具本体内存在剩余米饭，其中，第二预设时间小于第一预设时间，具体第一预设时间、第二预设时间和预设重量可根据实际情况进行标定，例如，第一预设时间可以为12h，第二预设时间可以为1h，预设重量可以为100g。
具体地，在烹饪器具完成烹饪进入保温状态后，根据通过称重装置获取器具本体内米饭的初始重量m1和实时获取的器具本体内米饭的实际重量m3，以实时获取器具本体内米饭的重量变化情况。
在实时获取到器具本体内米饭的重量变化情况后，可根据该重量变化情况来判断器具本体内是否存在剩余食物。例如，在煮饭完成后，用户没多久就会开始用餐，在用餐的过程中，器具本体内米饭的重量会不断变化，但在一段时间后，如用户用餐结束后，器具本体内的米饭将不再发生变化，而此时存在两种可能，一种情况是器具本体内已经无米饭，此时获得的重量值接近0g；另一种情况是器具本体内还剩余有米饭，此时获得的重量值将大于0g。所以，可通过判断一段时间内器具本体内米饭的重量是否发生变化，且重量值是否大于一定值来判断器具本体内是否存在剩余食物。
举例而言，假设煮米饭完成时获得的初始重量为1000g，用户用餐时食用了800g，那 么在用户用餐后的一段时间内，器具本体内米饭的重量都将维持在200g(大于预设重量100g)不变，此时可以判断器具本体内存在剩饭。然后在判断出器具本体内有剩饭后开始计时，或者在当前时间的基础上继续计时，当计时时间达到一定值(如12h)时，说明器具本体内的剩饭保留时间比较长，此时控制烹饪器具发出剩饭提示信息。例如，通过蜂鸣器、语音或指示灯对用户进行提醒，以便用户能够及时对剩饭进行处理，防止因用户长时间忘记而未进行处理等，导致剩饭口感变差，甚至是变质发臭，影响用户身体健康。
进一步地，图7是根据本申请一个实施例的烹饪器具的剩饭检测方法的流程图。如图7所示，该烹饪器具的剩饭检测方法可包括以下步骤：
S301，称重数据清零，选择煮饭功能和米种。
S302，提示用户需要添加的米量，用户按照提示加入相应的米量和水。
S303，开始煮饭。
S304，完成煮饭。
S305，保温或结束煮饭。
S306，煮饭完成后，采集称重装置的称重数据，并计算出初始饭量m1。
S307，在用户食用一定饭量m4后，最后剩余的饭量n3＝m1-m4。
S308，判断出n3≥100g且持续一段时间未变化。
S309，判断是否满足剩饭保留时间t≥设定的剩饭保留时间t2。如果是，执行步骤S310；如果否，返回步骤S309。
S310，提醒用户，以便用户能够及时处理。
其中，需要说明的是，由于剩饭保留时间设置的一般都比较长，如上述示例中的12h，而在此期间用户有可能出现用餐的情况，一种是重新煮饭，另一种是食用剩饭。其中，对于前一种情况，直接清除当前记录状态，重新开始即可。而对于后一种情况，由于在食用剩饭时会存在用户在剩饭的基础上进行再次烹饪，所以用户很可能重新选择煮饭，但是利用剩饭进行烹饪的保质期远没有重新烹饪的保质期长，所以此时不对当前记录状态进行清除，而是继续在此基础上进行计时。例如，可以增加一个相应的剩饭再烹饪按键，在用户开始煮饭之前，先按下该按键，以保留当前计时时间，然后开始烹饪，并按照上述方式判断用户用餐后是否仍然有剩饭存在，如果有，则继续在之前的计时时间的基础上进行计时，以防止因使用剩饭进行烹饪而导致的剩饭提醒不可靠的问题，防止剩饭对用户健康造成影响。
而且，由于剩饭保留时间设置的比较长，可以在烹饪器具内部设置一块电池，通过该 电池对剩饭提醒模块进行供电，以防止市电断电导致无法对用户进行提醒，从而进一步提高剩饭提醒的可靠性。此外，也可以增加相应的设置按键来对第一预设时间和预设重量进行设置，以实现个性化定制，满足不同用户以及不同地区的实际需求。例如，有些用户对于6小时后的剩饭就无法容忍；又如，高温潮湿地区的剩饭保留时间远没有低温干燥地区的保留时间长，所以可以通过相应按键来进行设置，以满足用户实际需求。
进一步地，在本申请的一个实施例中，烹饪器具与移动终端进行无线通信，其中，当器具本体内存在剩余米饭且持续时间达到第一预设时间时，还通过移动终端发出剩饭提示信息。
具体而言，如果烹饪器具与用户的移动终端进行了联网，并且当前处于联网状态，那么此时可以通过移动终端发出剩饭提示信息，以对用户进行实时提醒。例如，对于上班族来说，早上烹饪的食物过多未食用完，而经过了一天的繁忙工作，早已忘记家里还存有米饭，很可能买菜并重新烹饪，但是回家后发现烹饪器具还存有米饭，导致用户不知道该丢弃还是重新烹饪，或者用户已经在外就餐，而忘记家中还有米饭，所以未进行及时处理，当第二天早上想煮米饭时，发现烹饪器具内还存有米饭，此时又需要花费大量时间清理发霉发臭的食物，导致用户心情极度不好，大大降低用户体验。所以，通过移动终端对用户进行实时提醒，不管用户在家中还是外面，都可以实时了解到剩饭情况，这样用户根据剩饭情况就可以自由选择，有效避免上述情况的发生。
在本申请的另一个实施例中，烹饪器具与云服务器进行通信，其中，当器具本体内存在剩余米饭且持续时间达到第一预设时间时，烹饪器具还将剩余米饭信息发送给云服务器，云服务器对剩余米饭信息进行统计和分析，并根据分析结果生成米饭量提醒信息，以及在烹饪器具烹饪时向烹饪器具发送米饭量提醒信息。
具体而言，虽然在用户选择烹饪功能时会对用户所添加的米量和水进行提示，但是这些提示只是给出了米量添加的上限和下限，以及米量和水的比例关系，并非是根据用户的实际食用量来确定的，而且用户自身也无法准确把握实际所需米量，导致每次烹饪之后都有好多剩饭，给用户带来很大的困扰。
而在本申请的实施例中，可以在器具本体内存在剩余食物且持续时间达到第一预设时间时，即烹饪器具发出剩饭提示信息时，将剩余食物信息发送给云服务器，通过云服务器对剩余食物信息进行统计和分析，然后根据分析结果生成烹饪食物量提醒信息。例如，当连续三次的剩饭重量超过一定值(如200g)，则生成烹饪食物量提醒信息，如“剩饭量过多，请注意节约”等，并且在用户重新烹饪时，向烹饪器具发送该提醒信息，以提醒用户如果不是必须保留(如做蛋炒饭，剩饭会更好)，最好适当减少烹饪食物量，避免浪费。
另外，需要说明的是，在上述示例中均是以煮米饭为例，而本申请同样适用于煮粥、炖排骨、煲汤、制作蛋糕和酸奶等，具体这里不再详述。
由此，根据本申请实施例的烹饪器具的剩饭检测方法，在烹饪器具完成烹饪后，通过采集称重装置的称重数据以实时获取器具本体内的烹饪食物重量值，并根据实时获取的烹饪食物重量值判断器具本体内是否存在剩余食物，如果器具本体内存在剩余食物且持续时间达到第一预设时间，则控制烹饪器具发出剩饭提示信息，以提醒用户及时处理，防止因剩饭保留时间过长导致口感变差，甚至是变质发臭，影响用户身体健康。
另外，本申请的实施例还提出了一种非临时性计算机可读存储介质，其上存储有计算机程序，该程序被处理器执行时实现上述的烹饪器具的保温性能自动调节方法。
本申请实施例的非临时性计算机可读存储介质，通过执行上述的烹饪器具的保温性能自动调节方法，能够使得米饭保温性能更加精确，避免米饭表面发干、发黄以及表面滴白的情况，使得米饭的效果就像刚煮好一样。
图8是根据本申请实施例的烹饪器具的保温性能自动调节装置的方框示意图。
在本申请的实施例中，如图1所示，烹饪器具内设有称重装置30，称重装置30用于对器具本体进行称重，具体前面已经详述，这里就不再赘述。
如图8所示，该烹饪器具的保温性能自动调节装置，包括：重量获取模块100、开合盖检测模块200和控制模块300。
其中，重量获取模块100用于在烹饪器具进入保温状态时，通过称重装置30获取器具本体内米饭的初始重量；开合盖检测模块200用于在烹饪器具进入保温状态时对烹饪器具进行开合盖检测以判断烹饪器具在保温过程中是否进行开盖操作；控制模块300用于在烹饪器具在保温过程中进行开盖操作时，通过重量获取模块100实时获取器具本体内米饭的实际重量，并判断当前实际重量是否大于初始重量，其中，如果当前实际重量大于初始重量，则在烹饪器具内的温度达到预设的参考保温温度时控制烹饪器具的上盖保温目标温度减小和烹饪器具的上盖加热功率减小，并控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变。
根据本申请的一个实施例，控制模块300还用于当烹饪器具在保温过程中进行开盖操作时，如果当前实际重量小于初始重量，则控制烹饪器具的上盖保温目标温度增大和烹饪器具的上盖加热功率增大，并控制烹饪器具的底部加热功率减小，以及控制烹饪器具的底部保温目标温度保持不变。
根据本申请的一个实施例，控制模块300还用于当烹饪器具在保温过程中无开盖操作时，通过重量获取模块100实时获取器具本体内米饭的实际重量，并获取初始重量与当前实际重量的差值，以及判断初始重量与当前实际重量的差值是否大于第一预设阈值，其中， 如果初始重量与当前实际重量的差值大于第一预设阈值，则控制烹饪器具的底部保温目标温度减小和烹饪器具的底部加热功率减小，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变；如果初始重量与当前实际重量的差值小于等于第一预设阈值，则控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变。
根据本申请的一个实施例，控制模块300还用于在控制烹饪器具的底部保温目标温度减小和烹饪器具的底部加热功率减小、以及控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变之后，通过重量获取模块100获取器具本体内米饭的实际重量变化值，并判断器具本体内米饭的实际重量变化值是否大于第二预设阈值，其中，如果器具本体内米饭的实际重量变化值大于第二预设阈值，则控制烹饪器具的底部保温目标温度增大和烹饪器具的底部加热功率增大，并控制烹饪器具的上盖加热功率增大，以及控制烹饪器具的上盖保温目标温度保持不变；如果器具本体内米饭的实际重量变化值小于等于第二预设阈值，则控制烹饪器具的底部保温目标温度和烹饪器具的底部加热功率保持不变，并控制烹饪器具的上盖保温目标温度和烹饪器具的上盖加热功率保持不变。
根据本申请的一个实施例，控制模块300，还用于，在烹饪器具完成烹饪进入保温状态后，根据实时获取的器具本体内米饭的实际重量判断器具本体内是否存在剩余米饭，其中，
如果器具本体内存在剩余米饭且持续时间达到第一预设时间，则控制烹饪器具发出剩饭提示信息。
根据本申请的一个实施例，控制模块300进一步用于，根据实时获取的器具本体内米饭的实际重量获取器具本体内的米饭重量变化情况，并根据米饭重量变化情况判断器具本体内的烹饪米饭的实际重量在第二预设时间内维持不变且大于等于预设重量时，判断器具本体内存在剩余米饭，其中，第二预设时间小于第一预设时间。
进一步地，根据本申请的一个实施例，如图9所示，控制模块300与移动终端400进行无线通信，其中，当器具本体内存在剩余米饭且持续时间达到第一预设时间时，控制模块300还将剩饭提示信息发送给移动终端400，以通过移动终端400进行提示。
进一步地，根据本申请的另一个实施例，如图9所示，控制模块300还与云服务器500进行通信，其中，当器具本体内存在剩余米饭且持续时间达到第一预设时间时，控制模块300还将剩余米饭信息发送给云服务器500，云服务器500对剩余米饭信息进行统计和分析，并根据分析结果生成米饭量提醒信息，以及在烹饪器具烹饪时向烹饪器具发送米饭量提醒信息。
需要说明的是，本申请实施例的烹饪器具的保温性能自动调节装置中未披露的细节，请参照本申请实施例的烹饪器具的保温性能自动调节方法中所披露的细节，这里不再赘述。
