图4是根据本发明另一个实施例的电饭煲的结构框图。
具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的电饭煲及其控制方法。
在本发明的实施中,电饭煲包括加热器。
图1是根据本发明一个实施例的电饭煲的控制方法的流程图。如图1所示,该电饭煲的控制方法包括以下步骤:
S101,接收用户输入的烹饪指令。
具体地,电饭煲的控制面板上可以设置有米油烹饪选择按键,用户在使用电饭煲烹饪米油粥时,可以通过上述米油烹饪选择按键输入相应的烹饪指令。
S102,根据烹饪指令控制加热器以第一平均功率进行加热。
在本发明的一个实施例中,第一平均功率可以通过第一工作功率和第一调功比计算得到。
具体地,第一平均功率等于第一工作功率和第一调功比的乘积,即第一平均功率=第一工作功率*第一调功比。
其中,第一工作功率的取值范围可以为1200-1600W,如1600W;第一调功比的取值范围可以为14/16-16/16,如15/16,则第一平均功率的取值范围为1050-1600W,如1500W。例如,第一工作功率为1600W和第一调功比为15/16,则第一平均功率为1500W,即加热器以1600*(15/16)=1500W的功率进行加热。
可以理解,在本发明的一些实施例中,加热器可设置在电饭煲的底部,以较好实现对食物的均匀快速加热。
当然,在本发明的另一些实施例中,加热器可以是一个或多个,多个加热器中的部分可设置在电饭煲的底部,多个加热器中的部分还可设置在电饭煲的侧壁。
S103,获取电饭煲内的沸腾检测参数,并判断沸腾检测参数是否达到预设阈值。
在本发明的一个实施例中,沸腾检测参数可以为电饭煲内的蒸汽温度,其对应的预设阈值则为温度阈值。
具体地,检测电饭煲内的蒸汽温度,判断蒸汽温度是否达到预设温度,如果蒸汽温度达到温度阈值,则判断电饭煲内达到沸腾阶段,进行下一步控制。其中,温度阈值的取值范围可以为80-100℃,如85℃。
可选地,可以通过设置在电饭煲上盖的温度传感器检测电饭煲内的蒸汽温度。
在本发明的另一个实施例中,沸腾检测参数还可以为电饭煲内的气泡振动检测值、气泡电极检测值或气泡电容检测值。
具体地,以气泡振动检测值为例,可以在电饭煲内壁设置用于检测振动频率的感应装置,检测电饭煲烹饪时的振动频率,以在振动频率达到频率阈值时,判断电饭煲内存在气泡,即电饭煲内达到沸腾阶段,进行下一步控制。
以气泡电极检测值为例,可以在电饭煲内设置用于检测气泡位置的电极检测装置,根据检测的电极导通状态值判断电饭煲内气泡的位置,在气泡位置达到预设位置,如接近当前烹饪食物的顶部位置时,即可判断电饭煲内达到沸腾阶段,进行下一步控制。
以气泡电容检测值为例,可以在电饭煲内设置用于检测气泡位置的电容检测装置,根据检测的电容值判断电饭煲内气泡的位置,在气泡位置达到预设位置,如接近当前烹饪食物的顶部位置时,即可判断电饭煲内达到沸腾阶段,进行下一步控制。
在本发明的实施例中,加热器以第一平均功率进行加热直至沸腾,即沸腾检测参数达到预设阈值,可以析出米粒中的营养成分。
S104,如果沸腾检测参数达到预设阈值,则控制加热器以第二平均功率和第三平均功率交替进行加热,直至烹饪结束。
其中,第二平均功率大于第三平均功率,且可以进一步设定第二平均功率和第三平均功率均小于第一平均功率。
在本发明的一个实施例中,第二平均功率可以通过第二工作功率和第二调功比计算得到。
具体地,第二平均功率等于第二工作功率和第二调功比的乘积,即第二平均功率=第二工作功率*第二调功比。
其中,第二工作功率的取值范围可以为300-800W,如800W;第二调功比的取值范围可以为4/16-6/16,如6/16,则第二平均功率的取值范围为75-300W,如300W。例如,第二工作功率为800W和第二调功比为6/16,则第二平均功率为300W,即加热器以800*(6/16)=300W的功率进行加热。在本发明的一个实施例中,第三平均功率=第二工作功率*第三调功比。
其中,第二工作功率的取值范围可以为300-800W,如800W;第三调功比的取值范围可以为1/16-3/16,如2/16;则第三平均功率的取值范围为18.75-150W,如100W。
具体地,在接收用户输入的烹饪指令后,根据烹饪指令控制电饭煲的加热器以第一平均功率进行加热,并实时判断电饭煲内沸腾检测参数是否达到预设阈值,即电饭煲内是否达到沸腾阶段,在电饭煲内达到沸腾阶段时,控制加热器以第二平均功率和第三平均功率交替进行加热,直至烹饪结束,由此,能够实现电饭煲烹饪火力的自动控制,满足用户对米油的烹饪需求,且能够有效避免烹饪时的溢出。
在本发明的一个实施例中,控制加热器以第二平均功率和第三平均功率交替进行加热,具体包括以下步骤:
S201,在判断沸腾检测参数达到预设阈值之后开始计时。
S202,判断计时时间是奇数或是偶数。
其中,计时时间的单位可以为分钟,也可以为时间段,例如30秒为一个时间段。
S203,如果计时时间为奇数,则控制加热器以第二平均功率进行加热,并判断计时时间是否达到第一预设时间。
具体地,加热器以第二平均功率进行加热,可以使米粒沸腾剧烈,促使米粒煮烂。
S204,如果计时时间未达到第一预设时间且计时时间为偶数,则控制加热器以第三平 均功率进行加热。
具体地,加热器以第三平均功率进行加热,可以防止烹饪时的溢出。
当然,在本发明的一个实施例中,控制加热器以第二平均功率和第三平均功率交替进行加热,也可以为:如果计时时间为奇数,则控制加热器以第三平均功率进行加热,并判断计时时间是否达到第一预设时间;如果计时时间未达到第一预设时间且计时时间为偶数,则控制加热器以第二平均功率进行加热。
进一步地,在本发明的一个实施例中,电饭煲还包括设置在上盖的盖加热器。
具体地,在计时时间达到第一预设时间时,控制加热器停止工作,且控制盖加热器以第四平均功率进行加热,直至计时时间达到第二预设时间,以保证没有冷凝水滴在米油上。
其中,第一预设时间小于第二预设时间。
在本发明的一个实施例中,第一预设时间的取值范围可以为30-60分钟,如40分钟;第二预设时间的取值范围可以为60-120分钟,如80分钟。
在本发明的一个实施例中,第四平均功率=第二工作功率*第四调功比。
其中,第二工作功率的取值范围可以为300-800W,如800W;第四调功比的取值范围可以为8/16-16/16,如12/16;则第四平均功率的取值范围可以为150-800W,如600W。
在本发明的一个示例中,在计时时间达到第一预设时间时,还可以发出提示信息以提醒用户打开电饭煲的上盖。
具体地,在计时时间达到第一预设时间时,可以控制设置在电饭煲上的提示装置(如蜂鸣器)发出提示信息(如“嘀嘀嘀”的声音)以提醒用户打开上盖,以保证没有冷凝水滴在米油上。
结合图1、图2,根据本发明的上述实施例,在本发明的一个具体示例中,电饭煲实现米油烹饪过程的原理可如下:
S1,沸腾前阶段:电饭煲开始米油功能烹饪后,首先设置加热系统的工作功率W1(即第一工作功率),然后使用调功比为N1(即第一调功比)进行烹饪,即加热器以第一平均功率进行加热,以析出米粒中的营养成分。
S2,中火沸腾阶段:当设置在上盖的温度传感器检测到的蒸汽温度达到T(即温度阈值)时,切换加热系统的工作功率为W2(即第二工作功率),开启定时器T1,当定时器T1计时分钟数为奇数时,使用调功比为N2(即第二调功比)进行米油烹饪,即加热器以第二平均功率进行加热,以使米粒沸腾剧烈,促使米粒煮烂,其中,N2<N1。
S3,小火沸腾阶段:当定时器T1计时分钟数为偶数时,使用调功比为N3(即第三调功比)进行米油烹饪,即加热器以第三平均功率进行加热,以防止烹饪时的溢出,其中,N3<N2。
S2、S3一直间隔循环。
S4,米油形成阶段:计时器T1计时达到设定值t1(第一预设时间)后,开启定时器 T2,控制设置在电饭煲底部的加热器不工作,控制设置在上盖的盖加热器以调功比N4(即第四调功比)加热,即盖加热器以第四平均功率进行加热,并一直维持S4阶段直至T2计时达到设定值t2(即第二预设时间);或者计时器T1计时达到设定值t1(第一预设时间)后,控制蜂鸣器发出提示信息以提醒用户打开上盖自然冷却。即在t1-t2时间内,加热器不加热,只有盖加热器加热,或者,打开上盖,由此,保证没有冷凝水滴在米油上。
综上,本发明实施例的电饭煲的控制方法,在接收用户输入的烹饪指令后,根据烹饪指令控制电饭煲的加热器以第一平均功率进行加热,并实时判断电饭煲内的沸腾检测参数是否达到预设阈值,即电饭煲内是否达到沸腾阶段,在电饭煲内达到沸腾阶段时,控制加热器以第二平均功率和第三平均功率交替进行加热,并开始计时,计时分钟数小于第一预设时间且为奇数时,控制加热器以第二平均功率进行加热,计时分钟数小于第一预设时间且为偶数时,控制加热器以第三平均功率进行加热,在计时时间达到第一预设时间且小于第二预设时间时,只控制设置在电饭煲上盖的盖加热器以第四平均功率进行加热,直至计时时间达到第二预设时间时,烹饪结束,或者在计时时间达到第一预设时间时,发出提示信息以提醒用户打开上盖自然冷却,由此,能够实现电饭煲烹饪火力的自动控制,满足用户对米油的烹饪需求,且能够有效避免烹饪时的溢出。

其中,接收模块10用于接收用户输入的烹饪指令。判断模块20用于获取电饭煲内的沸腾检测参数,并判断沸腾检测参数是否达到预设阈值。控制模块40分别与接收模块10、判断模块20和计时器30相连,用于根据烹饪指令控制加热器以第一平均功率进行加热,以及在电饭煲内的沸腾检测参数达到预设阈值时控制加热器以第二平均功率和第三平均功率交替进行加热,直至烹饪结束,其中,第二平均功率大于第三平均功率。
可以理解,第二平均功率和第三平均功率均小于第一平均功率。
