Description

烹饪设备及其控制方法和控制装置 技术领域
本发明涉及家用电器技术领域，特别涉及一种烹饪设备的控制方法、一种烹饪设备的控制装置以及一种烹饪设备。
背景技术
目前，电压力锅均通过位移检测压力开关来对电压力锅的加热进行控制。具体控制的方案如下：压力开关闭合，使得发热管通电加热，在加热的过程中，电压力锅内的压力值会增加，从而推动压力开关产生位移，当位移达到一定的距离时，压力开关断开，从而使得发热管停止加热，电压力锅内的压力值会随着温度的下降而减小，当压力值减小到一定的范围时，压力开关会重新闭合，使得发热管继续通电加热，如此循环，能够控制电压力锅内的压力值保持在预定的范围值之内。
当前的控制方案会造成压力开关频繁进行移动，影响压力开关的寿命，从而影响电压力锅的使用寿命，并且由于电压力锅内的压力值与压力开关的位移相关，因此，压力值所能保持的范围值受到压力开关的精度影响；而且由于压力开关容易失效，所以会产生电压力锅内出现异常高压或者泄压的隐患。

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。
在提出本发明实施例之前，首先需要说明的是，由于烹饪设备的内胆体积是不变的，因此，根据理想气体状态方程可以确定烹饪设备内胆的内腔温度值与压力值之间的映射关系，具体地，理想气体状态方程为：pV＝nRT，其中，R是气体常量；p为理想气体压强，单位Pa；V为气体体积，单位m3；n为气体的物质的量，单位mol，T为温度，单位K。从理想气体状态方程可以看出，对于气体来说，由于烹饪设备内胆体积不变，所以在气体体积不变的前提下，气体温度和气体的压强成正比，因此，对于烹饪设备来说，可以得到一个结论：控制内胆的气体压力与控制内胆的气体温度是等价的。基于该结论，提出本发明的以下实施例。
实施例一
参见图1，其示出了本发明实施例提供的一种烹饪设备的控制方法，所述压力烹饪设备包括加热装置、内胆、压力检测装置和温度传感器，所述方法包括以下步骤：
S101：在加热装置的加热过程中，通过压力检测装置检测内胆的内腔压力值；
S102：当检测到的压力值上升至预设的第一压力阈值时，通过温度传感器检测当前对应的第一温度值；
S103：当检测到的压力值从预设的第一压力阈值下降至预设的第二压力阈值时，通过温度传感器检测当前对应的第二温度值；
S104：按照预设的设定策略以及所述第一温度值与所述第二温度值获取温度基准值；
S105：将所述温度传感器检测到的当前温度值与所述温度基准值进行比较，并根据比较结果控制加热装置的开启和关闭。
需要说明的是，图1所示的技术方案可以应用于具有内胆的烹饪设备中，该烹饪设备中可包括有上盖、锅体和内胆；其中，内胆设置于锅体内，上盖设置于锅体上方并与锅体连接，从而使得上盖与锅体闭合时，将内胆进行密封。如图2所示，内胆2的底部21和侧壁22形成内腔23，用于盛放烹饪食材。通过上述针对烹饪设备的描述可以得知，该烹饪设备优选地可以为电压力锅、电饭煲等烹饪器具。
通过图1所示的技术方案，可以看出，由于气体温度和气体的压强成正比，因此，根据压力检测装置检测到的压力值所对应的温度值确定温度基准值之后，可以通过温度传感 器所监测到的温度值来控制烹饪设备的加热装置的开启和闭合，从而减少了压力检测装置的使用频次，避免压力检测装置例如压力开关的损坏，增加了烹饪设备的使用寿命，并且由于通过温度值控制加热装置的开启和闭合，能够更加精准和稳定地控制烹饪设备内胆的压力。
通常来说，烹饪设备的压力检测装置具体可利用浮子上浮用磁性驱动磁敏感元件，或根据理想状态方程利用温度检测来间接检测压力等，在本实施例中，可以为位移检测压力开关，当烹饪设备内胆的内腔压力值上升时，内胆的压力会使得压力开关产生位移，从而通过位移来表征烹饪设备内胆的内腔压力值，当压力值达到一定的阈值时，压力开关的位移较大，会导致压力开关断开，从而使得烹饪设备的加热装置停止加热，而当压力值再减小时，压力开关由于位移又会使得自身闭合，从而使得烹饪设备的加热装置继续加热。
因此，当检测到的压力值上升到预设的第一压力阈值时，图1所示的所述方法还可以包括：控制所述加热装置关闭。
需要说明的是，当加热装置关闭后，烹饪设备内胆的气体会自然冷却，温度会逐渐降低，根据理想气体状态方程，内胆的内腔压力值也会随之下降，从而当下降至预设的第二压力阈值时，可以通过所述温度传感器检测当前对应的第二温度值。
此外，当内胆的内腔压力值下降至第二压力阈值时，压力开关开始闭合，此时，图1所示的所述方法还可以包括：控制所述加热装置开启，继续给烹饪设备内胆进行加热。
压力检测装置所检测到的压力值在上升至第一压力阈值时，会关闭加热装置；而在关闭加热装置后，当压力检测装置检测到的压力值下降至第二压力阈值时又会开启加热装置，因此，在烹饪设备的工作过程中，压力检测装置检测到的压力值会不止一次上升至第一压力阈值，也不止一次会下降至第二压力阈值。
因此，对于步骤S102来说，第一温度值可以是检测到的压力值第一次上升到预设的第一压力阈值时进行检测，也可以是第二或第三或以上次上升到预设的第一压力阈值时进行检测，本实施例对此不作具体限定。
相应地，对于步骤S103来说，第二温度值也可以是检测到的压力值在上升到预设的第一压力阈值后第一次下降至预设的第二压力阈值时进行检测，也可以是第二或第三或以上次下降至预设的第二压力阈值时进行检测，本实施例对此不作具体限定。
优选地，在本发明的一个实施例中，对于步骤S104，按照预设的设定策略以及所述第一温度值与所述第二温度值获取温度基准值，在具体实现过程中可以包括：
将所述第一温度值至所述第二温度值的温度值范围内的任一温度值设置为温度基准值，其中，所述温度基准值小于所述第一温度值且不小于所述第二温度值。
优选地，在本发明的另一个实施例中，对于步骤S104，按照预设的设定策略以及所述 第一温度值与所述第二温度值获取温度基准值，在具体实现过程中可以包括：
按照下式获取温度基准值Tm：
Figure PCTCN2017092120-appb-000003
其中，T1为第一温度值，T2为第二温度值，T修正为预设的修正温度值。在本实施例中，T修正可以优选为5摄氏度。
示例性地，对于步骤S105，将所述温度传感器检测到的当前温度值与所述温度基准值进行比较，并根据比较结果控制加热装置的开启和关闭，具体可以包括：
若所述当前温度值大于或等于所述温度基准值，则控制加热装置关闭；
若所述当前温度值小于所述温度基准值，则控制加热装置开启。
此外，需要说明的是，当根据比较结果控制加热装置的开启和关闭之后，烹饪设备的加热装置的开启和关闭是通过温度传感器所检测到的温度与温度基准值之间的比较进行控制，因此，不再是通过压力开关的开启和关闭进行控制，所以能够避免由于压力检测装置的精度影响烹饪设备的压力范围，而且还能够更加稳定的控制产品内部的温度，缩减变化范围。
示例性地，在根据比较结果控制加热装置的开启和关闭之后，还可以对温度基准值进行更新，具体地，所述方法还包括：
当所述检测到的压力值再次上升到预设的第一压力阈值时，通过所述温度传感器检测当前对应的第三温度值；
按照预设的设定策略以及所述第三温度值与所述第二温度值对所述温度基准值进行更新。
具体来说，按照预设的设定策略以及所述第三温度值与所述第二温度值对温度基准值进行更新的实现过程与前述按照预设的设定策略以及所述第一温度值与所述第二温度值获取温度基准值的过程相同，将获取的新的温度基准值代替之前获取的温度基准值，本实施例对此不再赘述。
本实施例提供的烹饪设备的控制方法，通过温度传感器所监测到的温度值来控制烹饪设备的加热装置的开启和闭合，减少了压力检测装置的使用频次，增加了烹饪设备的使用寿命，并且由于通过温度值控制加热装置的开启和闭合，能够更加精准和稳定地控制烹饪设备内胆的压力。
实施例二
基于前述实施例相同的技术构思，本实施例通过以下具体示例对上述实施例的技术方 案进行详细说明。由于压力检测装置所检测到的压力值在上升至第一压力阈值时，会关闭加热装置；而在关闭加热装置后，当压力检测装置检测到的压力值下降至第二压力阈值时又会开启加热装置，因此，在烹饪设备的工作过程中，压力检测装置检测到的压力值会不止一次上升至第一压力阈值，也不止一次会下降至第二压力阈值。
示例一
参见图3，本示例所示的控制方法具体流程可以包括：
S301：加热并检测内胆的内腔压力值；
S302：判断检测到的压力值是否大于第一压力阈值P1；若是，则转至S303；否则，转至S301继续加热并检测内胆的内腔压力值；
S303：关闭加热装置并检测内胆的内腔压力值；
可以理解地，当关闭加热装置之后，内胆的温度会逐渐下降，压力值也会随之下降。
S304：判断检测到的压力值是否小于或等于第二压力阈值P2；若是，则转至S305；否则，转至S303继续执行检测内腔压力值；
S305：记录此时的温度值Ton，开启加热装置并检测内胆的内腔压力值；
S306：判断检测到的压力值是否大于第一压力阈值；若是，则转至S307；否则，转至S305，继续执行检测内胆的内腔压力值；
S307：记录此时的温度值Toff，并关闭加热装置；
S308：根据Ton和Toff设定温度基准值Tm，并检测内胆的内腔温度值T；
S309：判断T是否小于Tm；若是，则转至S310；否则，转至S307，保持加热装置关闭；
S310：开启加热装置。
后续的工作过程可以通过执行S309来实现针对内胆温度值进行检测，当T小于Tm则开启加热装置进行加热，否则关闭加热装置。
结合图4所示的烹饪设备工作曲线，在该曲线中，由于烹饪设备内的温度值和压力值呈正比关系，因此，可以结合在同一个曲线中进行说明。通过该曲线可以看出：当内胆的内腔压力值第一次上升至第一压力阈值时，并没有检测此时的温度值，而是在第二次上升至第一压力阈值时检测到Toff；而内胆的内腔压力值第一次下降至第二压力阈值时，检测到Ton，并根据Ton和Toff获取Tm，从而使得后续的工作曲线仅在Tm的附近范围波动，而并非是在第一压力阈值P1和第二压力阈值P2之间波动，因此，针对压力或温度的控制更加的精确和稳定。
通过图3所示的过程，烹饪设备的加热装置在工作过程中通过检测到的温度值控制加热装置的开启和关闭，与现有技术中通过压力开关进行控制的方案相比，能够减少压力开 关的使用频次，更加精准和稳定地控制烹饪设备内胆的压力。
示例二
参见图5，本示例所示的控制方法具体流程可以包括：
S501：加热并检测内胆的内腔压力值；
S502：判断检测到的压力值是否大于第一压力阈值P1；若是，则转至S503；否则，转至S501继续加热并检测内胆的内腔压力值；
S503：记录此时的温度值Toff，关闭加热装置并检测内胆的内腔压力值；
S504：判断检测到的压力值是否小于或等于第二压力阈值P2；若是，则转至S505；否则，转至S503继续保持加热装置关闭且检测内胆的内腔压力值。
S505：记录此时的温度值Ton，开启加热装置并检测内胆的内腔压力值；
S506：根据Ton和Toff设定温度基准值Tm，并检测内胆的内腔温度值T；
S507：判断T是否小于Tm；若是，则转至S508；否则，关闭加热装置；
S508：保持加热装置开启并检测内胆的内腔压力值；
需要说明的是，当加热装置开启时，内胆的内腔压力值还会上升至第一压力阈值，因此，还可以对温度基准值进行更新，因此，还可以包括：
S509：判断检测到的压力值是否小于第一压力阈值P1；若是，则继续加热；否则，转至S510：记录此时的温度值T’off，并根据Ton和T’off设定温度基准值T’m。
后续的工作过程可以针对内腔温度值进行检测，当T小于T’m则开启加热装置进行加热，否则关闭加热装置。
结合图6所示的烹饪设备工作曲线，可以看出，在该曲线中，由于烹饪设备内的温度值和压力值呈正比关系，因此，可以结合在同一个曲线中进行说明。通过该曲线可以看出：当内胆的内腔压力值第一次上升至第一压力阈值时，检测到Toff；并且内胆的内腔压力值第一次下降至第二压力阈值时，检测到Ton，并根据Ton和Toff获取Tm，从而使得后续的工作曲线仅在Tm的附近范围波动，而并非是在第一压力阈值P1和第二压力阈值P2之间波动，因此，针对压力或温度的控制更加的精确和稳定
