上述说明仅是本公开技术方案的概述，为了能够更清楚了解本公开的技术手段，而可依照说明书的内容予以实施，并且为了让本公开的上述和其它目的、特征和优点能够更明显易懂，以下特举本公开的具体实施方式。
附图说明
为了更清楚地说明本公开实施例或相关技术中的技术方案，下面将对实施例或相关技术描述中所需要使用的附图作简单地介绍，附图仅用于示出优选实施方式的目的，而并不认为是对本公开的限制。
图1为本公开实施例中一种烹饪器具的泄压方法的流程图；
图2为本公开实施例中一种烹饪器具的泄压方法的具体实现流程图；
图3为本公开实施例中一种烹饪器具的泄压装置结构图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开实施例中烹饪器具可以为具有快速泄压功能的压力锅、电饭煲等。该烹饪器具可以包括压力传感器、排气控制模块、排气阀、快速泄压模块、温度传感器以及锅体。快速泄压模块可以是风冷冷却泄压、水冷冷却泄压、水雾式风冷冷却泄压等冷却锅内以达到快速泄压的方式。排气控制模块可以是电磁阀控制排气，电磁位移器顶起重锤控制排气等排气控制方式。
图1示出了本公开实施例提出的一种烹饪器具的泄压方法的流程图。如图1所示，本公开实施例提出的烹饪器具的泄压方法包括如下步骤：
S11、当烹饪器具开启快速泄压功能时，获取烹饪器具的内锅压力。
本公开实施例中，烹饪器具的锅内压力可以通过多种方式获取。例如，可以直接通过在烹饪器具内部可以设置压力传感器，通过压力传感器直接检测烹 饪器具的锅内压力。例如，还可以在烹饪器具内部设置温度传感器，可以通过温度换算得到锅内压力。
S12、判断所述内锅压力是否满足预设的进入排气阶段的执行条件。
S13、若所述内锅压力满足所述进入排气阶段的执行条件，控制所述烹饪器具停止执行所述快速泄压功能，并对快速泄压功能的停止时间进行计时。
本公开实施例中，泄压阶段时快速泄压模块持续运行，并实时获取内锅压力，以判断是否满足预设的进入排气阶段的执行条件，在内锅压力满足进入排气阶段的执行条件准备执行排气操作之前，预先控制烹饪器具停止执行快速泄压功能，并对快速泄压功能的停止时间进行计时，以便后续可以在停止时间到达预设的第一时间阈值时，控制所述烹饪器具进行排气，这样可以在排气前平复锅内微沸的状态，避免排气溢出的情况。
S14、当所述停止时间到达预设的第一时间阈值时，控制所述烹饪器具根据与所述内锅压力对应的排气占空比进行排气。
在本公开实施例中，可以预先通过多次实验测试得到锅内压力与排气占空比之间的对应关系。例如，锅内压力与排气占空比之间的对应关系可以为锅内压力与排气占空比的对照表，还可以是锅内压力与排气占空比之间的函数关系式。当然，本公开实施例仅仅是对锅内压力与排气占空比之间的对应关系进行举例说明，对此本公开不作具体限定。
本公开实施例提出的烹饪器具的泄压方法，在每次进入排气阶段前控制快速泄压功能停止运行，并在预设时间后控制所述烹饪器具根据与内锅压力对应的排气占空比进行排气，能够在避免溢出的情况下，充分利用排气与快速冷却功能，进一步缩短快速泄压烹饪器具的泄压时间，同时促进泄压阶段中锅内食物的翻滚沸腾，提升烹饪效果。
本公开实施例提供的烹饪器具的泄压方法还包括：预先将烹饪器具执行快速泄压功能时的内锅压力划分为多个压力区间，其中，将每个压力区间设置为一个对应的排气阶段，各个压力区间对应的排气阶段的排气占空比随着压力区 间的压力降低而增大。
本公开实施例中，预先按照锅内压力由高到低的顺序，设置有多个压力区间，将每个压力区间即为一个对应的排气阶段，再根据压力区间的锅内压力与排气占空比的对应关系，得到每一压力区间与排气占空比之间的对应关系。
例如，在本公开实施例中，若锅内压力P>P1，则通过快速泄压模块降压至P1。
当锅内压力P∈(P2，P1]时，以D1排气占空比排气降压至P2；
当锅内压力P∈(P3，P2]时，以D2排气占空比排气降压至P3；
当锅内压力P∈(P3，P4]时，以D3排气占空比排气降压至P4；
......
依此类推，直至锅内压力P∈(0，Pn]时，以Dn排气占空比排气降压至0。
其中，D1<D2<D3.....<Dn，由于高压时排气更容易溢出，因此排气占空比小，低压时排气不易溢出，因此排气占空比大。
可理解的，在本公开一个可选实施例，还可以根据压力区间的锅内压力与排气频率的对应关系，得到每一压力区间与排气频率之间的对应关系，通过控制排气频率实现烹饪器具的泄压控制，具体对应关系如表1所示：
表1压力区间与排气频率之间的对应关系表
由表1可知，由于高压时排气更容易溢出，因此排气频率小，低压时排气不易溢出，因此排气频率大。
在一些实施方式中，本实施例中步骤S12的判断所述内锅压力是否满足预设的进入排气阶段的执行条件，具体包括：判断所述内锅压力是否到达各个排气阶段的压力区间，当所述内锅压力到达任一排气阶段的压力区间时，判定所述内锅压力满足进入当前排气阶段的执行条件。
在一些实施方式中，本实施例中步骤S14中的控制所述烹饪器具根据与所述内锅压力对应的排气占空比进行排气，具体包括以下附图中未示出的步骤：
S141、在根据所述排气占空比进行排气的每一排气周期中，当前周期排气结束后，控制所述烹饪器具执行所述快速泄压功能，并对进入下一次排气周期的时间进行倒计时；
S142、当距离进入下一次排气周期的计时时间到达第二时间阈值时，控制所述烹饪器具停止执行所述快速泄压功能。
在一个具体实施例中，第一时间阈值可以与第二时间阈值相同。在一些实施方式中，第一时间阈值的取值可以为[1s，20s]。
可理解的是，每次排气前快速泄压功能的停止运行时间t可以不同，但只要皆在[1s，20s]范围内即可。
如图2所示，本公开实施例提供的烹饪器具的泄压方法，在泄压全程，烹饪器具将按照一定逻辑实现快速泄压功能的持续运行，具体如下：
当烹饪器具开启快速泄压功能时，快速泄压功能持续运行，到第一预设排气占空比对应的压力区间或温度时，快速泄压功能停止，预设时间t后进行排气，单次排气结束后，快速泄压功能运行。下次排气的前t秒，快速泄压功能停止，单次排气结束后，快速泄压模块运行，以此类推，直至本排气阶段结束。当到下一预设排气占空比对应的压力区间或温度时，即每次排气占空比改变时，快速泄压模块先停止t秒后开始次排气阶段的第一次排气，按上述排气+快速泄压方式进行泄压，直至泄压完成。
本公开实施例，在每次排气之前预先控制烹饪器具的快速泄压功能停止运行时间t，待排气结束后再继续运行。每次排气占空比改变时，快速泄压模块 先停止t秒后开始次排气阶段的第一次排气。这样通过采用排气泄压与快速冷却功能交替运行的方式，可以在排气前平复锅内微沸的状态，避免排气溢出的情况，进一步缩短快速泄压压力锅的泄压时间，促进锅内食物翻滚，提升烹饪效果。
对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本公开实施例并不受所描述的动作顺序的限制，因为依据本公开实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本公开实施例所必须的。
