如图1所示，本申请一实施例中，提供一种烹饪电器200。在一些实施方式中，烹饪电器200为压力电饭煲。烹饪电器200包括盖体210和锅体230，盖体210相对锅体230可开合设置，以打开或封闭锅体230中的烹饪空间。
盖体210包括本体212及压力调节装置100，压力调节装置100设于本体212，用于调节烹饪电器200的内部压力，通过压力调节装置100能够在烹饪过程中灵活改变锅体230内部压力，满足多种烹饪需求。
如图2-3所示，压力调节装置100装配于盖体210中的本体212上，且包括支架10、加压阀50及减压阀70。其中，加压阀50开启时，烹饪电器200内部开始蓄压，压力增大；减压阀70开启时，烹饪电器200内部开始泄压，压力降低。在一些实施方式中，加压阀50和减压阀70均装配于支架10。
压力调节装置100还包括调压件30，调压件30相对支架10往复移动，加压阀50和减压阀70分布于调压件30的移动路径上。其中，调压件30在移动过程中，可选择地开启加压阀50和减压阀70中的任意一者。
在一些实施方式中，若调压件30在移动过程中开启加压阀50，锅体230内部蓄压，压力增大；若调压件30在移动过程中开启减压阀70，锅体230内部泄压，压力减小。如此，通过调压件30控制加压阀50及减压阀70的启闭，调压件30移动过程中可选择地开启加压阀50或者减压阀70，能够灵活地增加或降低锅体230内的压力，调压范围较大， 能够满足更多的烹饪需求。
调压件30包括主体32和凸出设置于主体32的作动部34，作动部34随主体32移动，并可选择地向加压阀50和减压阀70中的任意一者施加按压力，以通过按压力开启对应的阀门。因为，作动部34凸出主体32设置，作动部34在移动过程中，能够对与其抵接的部件施加按压力。在一些实施方式中，加压阀50和减压阀70位于作动部34的移动路径上，当作动部34经过加压阀50时，作动部34抵接加压阀50并对加压阀50施加按压力，以开启加压阀50，使烹饪电器200内部升压。当作动部34经过减压阀70时，作动部34抵接减压阀70并对减压阀70施加按压力，以开启减压阀70，使烹饪电器200内部降压。
加压阀50形成有第一排气口51且包括加压杆52，减压阀70形成有第二排气口71且包括减压杆72，作动部34随主体32移动时，可选择地抵接加压杆52和减压杆72中的任意一者，通过推动加压杆52或者减压杆72来调节压力。作动部34与加压杆52抵接时，加压杆52向靠近第一排气口51的方向移动，并封闭第一排气口51，以开启加压阀50进行蓄压。作动部34与减压杆72抵接时，减压杆72向远离第二排气口71的方向移动，并打开第二排气口71，以开启减压阀70进行泄压。需要说明的是，加压阀50和减压阀70只要能够实现加压和减压的功能即可，对于加压阀50和减压阀70中的其他部件在此不做赘述。
作动部34包括倾斜面341，倾斜面341相对主体32的移动方向倾斜设置，倾斜面341能够与加压阀50和减压阀70中的任意一者抵接，以开启对应的阀门。在作动部34上设置倾斜面341，一方面通过倾斜面341逐渐按压阀杆，逐渐关闭或打开排气口，使调压过程存在一定的缓冲段，防止烹饪电器200内部压力突然变化，保障使用安全。同时，通过倾斜面341与阀杆的配合，能够将阀杆下压至多种位置处，当阀杆移动至与排气口较近时，阀杆与排气口之间的间隙较小，泄压较慢，蓄压较快；当阀杆移动至与排气口较远时，阀杆与排气口之间的间隙较大，泄压较快，蓄压较慢。如此，通过倾斜面341控制阀杆移动的深度，便能够控制泄压及蓄压的快慢，进而实现多种泄压方式。
作动部34还包括与主体32的移动方向平行设置的水平面343，倾斜面341与水平面343沿主体32的移动方向分布，倾斜面341过渡连接于水平面343和主体32之间，水平面343能够与加压阀50和减压阀70中的任意一者抵接。如此，作动部34上设置水平面343，在调压件30移动时，移动的水平面343能够与阀杆抵接，并在水平面343下压阀杆的过程中，阀杆下压的深度恒定不变，能够使加压阀50或减压阀70处于恒定的调压状态。并且，通过倾斜面341过渡连接水平面343和主体32，过渡面逐渐作动阀杆，使阀杆的位置逐渐变化，保证调压过程的稳定性。
在一些实施方式中，作动部34相对主体32的距离最远处为水平面343，当水平面343与阀杆抵接时，阀杆被下压至最深处，例如加压阀50中加压杆52完全密封第一排气口51，减压阀70中减压杆72与第二排气口71之间的间距最大，加压阀50和减压阀70在水平面343作用下到达调节极限。
在一些实施方式中，倾斜面341包括第一倾斜面342和第二倾斜面344，第一倾斜面342和第二倾斜面344分别设于水平面343相对的两侧，且第一倾斜面342和第二倾斜面344由水平面343向相互远离的方向倾斜延伸至主体32，如此第一倾斜面342和第二倾斜面344向相反的方向倾斜，能够通过倾斜方向相反的两个面灵活控制阀杆的升降。例如，当主体32保持沿同一方向移动，第一倾斜面343、水平面343及第二倾斜面344依次经过加压阀50时，第一倾斜面343按压加压阀杆52，第二倾斜面344释放加压阀杆52。或者，能够将作动部34设于加压阀50和减压阀70之间，第一倾斜面342靠近加压阀50，第二倾斜面344靠近减压阀70，若需要增压便带动作动部34向靠近加压阀50的方向移动，并在第一倾斜面342及水平面343的作用下开启加压阀50；若需要降压便带动作动部34向靠近减压阀70的方向移动，并在第二倾斜面344及水平面343的作用下开启减压阀70。同样地，当需要释放阀门时，将与阀门抵接的水平面343，向第一倾斜面342和第二倾斜面344中的任意一者移动，便能够使阀杆逐渐复位。如此，在水平面343两侧设置倾斜方向相反的第一倾斜面342和第二倾斜面344，能够允许调压件30根据压力需求灵活移动。
压力调节装置100还包括驱动机构90，驱动机构90为调压件30提供相对支架10往复移动的驱动力，自动化驱动调压件30移动，进而自动化调压。在一些实施方式中，通过控制驱动机构90来控制调压件30的移动过程，使调压件30根据压力需求移动至合适的位置，并将烹饪电器200内部的大气压调节至需要的压力值。
驱动机构90包括驱动件92及传动组件94，驱动件92设于支架10，传动组件94连接于驱动件92与调压件30之间，传动组件94在驱动件92的驱动下，带动调压件30相对支架10往复移动。在一些实施方式中，驱动件92为电机，传动组件94将电机输出的旋转运动，转化为调压件30的往复移动，进行自动化调压。
传动组件94包括齿轮941和齿条943，齿轮941与驱动件92的输出端连接，齿条943固定于调压件30；齿轮941与齿条943齿牙啮合传动，带动调压件30沿齿条943的延伸方向往复移动。如此，在齿轮941与齿条943的配合下，能够可靠地驱动调压件30往复移动。在其他一些实施例中，传动组件94为丝杆传动等传动方式，在此不做限定。
本申请一实施例中，还提供一种上述压力调节装置100。压力调节装置100装配于盖体210中的本体212上，且包括支架10、加压阀50及减压阀70，加压阀50开启时，烹 饪电器200内部开始蓄压，压力增大；减压阀70开启时，烹饪电器200内部开始泄压，压力降低。在一些实施方式中，加压阀50和减压阀70均装配于支架10。压力调节装置100还包括调压件30，调压件30相对支架10往复移动，加压阀50和减压阀70分布于调压件30的移动路径上。其中，调压件30在移动过程中，可选择地开启加压阀50和减压阀70中的任意一者。在一些实施方式中，若调压件30在移动过程中开启加压阀50，锅体230内部蓄压，压力增大；若调压件30在移动过程中开启减压阀70，锅体230内部泄压，压力减小。如此，通过调压件30控制加压阀50及减压阀70的启闭，调压件30移动过程中可选择地开启加压阀50或者减压阀70，能够灵活地增加或降低锅体230内的压力，调压范围较大，能够满足更多的烹饪需求。
以上所述实施例的各技术特征允许进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还能够做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
