Description

压力锅
本实用新型涉及一种厨具压力锅技术领域。
压力锅成为现代家庭中必备厨具之一,深受人们欢迎,但是,我们常用的压力锅以14厘米左右长手柄为主,其缺点是长手柄安装易松动、易折断、使用时放置不方便,并且多占空间,造成包装运输成本提高。另外我们常用压力锅其开合盖安全装置,需上手柄中推板配合使用,就是讲要打开锅盖时,旋转手柄同时附加推板动作,才能开启,这样造成使用上不方便。
本实用新型的目的在于提供一种结构牢靠、使用方便、占空间体积较小、易于包装运输的压力锅。
本实用新型的技术方案是这样实现的。该压力锅包括有锅身、锅盖、密封圈、限压阀、安全阀、开合盖安全装置、手柄,锅盖扣合在锅身的锅牙上,同时锅盖与锅身接触面处设有密封圈,锅盖顶部分别安装有限压阀和安全阀,锅盖、锅身上有上、下手柄,其特征在于:上手柄安装在锅盖顶部,并且手柄整体限于锅盖上方圆周空间内;下手柄为7厘米长范围内的短手柄、大体对称地安装在锅身两侧上。
上述开合盖安全装置为固定在锅盖上的侧手柄内空腔中活动式固定有偏心轮,偏心轮下部设有顶销通过锅盖边沿开孔顶在锅身牙上,偏心轮上通过销子穿过安全板开孔压有安全板,同时安全板有卡脚卡扣在偏心轮上,前部有扣孔与销子之间连有弹簧,锅盖在安全板头部附件内开孔装有可随锅内气压大小而升降的自锁阀。
该压力锅采用长手柄旋合式改为锅盖顶部手握旋合式,开合盖安全装置无需推钮操作,使压力锅开合更加方便容易,手柄固定更加牢靠、不易折断,并且减少压力锅占有空间体积,便于包装运输,外观也美观独特。

下面结合附图说明对本实用新型的实施例作进一步详细描述:
如图所示,该压力锅有锅身2、锅盖15、密封圈17、限压阀21、安全阀18、开合盖安全装置、手柄,上手柄10通过螺钉11与支承座19固连后,固定在锅盖顶部,并且手柄整体限于锅盖上方圆周空间内,其内部呈中空状,装有防暴安全装置,如图4所示,侧部开有出气孔,对应锅盖顶部微凹处开有数个小孔,压有密封垫14和压板13,支承座19也用螺钉20固定在上手柄空腔中锅盖上,  压板与支承座之间顶有弹簧12。锅盖顶部安装有安全阀和限压阀外,还固定有短型侧手柄4,内部空腔内活动式固定有偏心轮5,偏心轮下部设有顶销通过锅盖边沿开孔顶在锅身牙上,偏心轮上通过销子6穿过安全板8的开孔压有安全板8,同时安全板有卡脚卡扣在偏心轮上,前部有扣孔与销子之间连有弹簧7,锅盖在安全板头部附近内开孔装有可随锅内气压大小而升降的自锁阀9,如图8和图2所示。下手柄3为7cm长内的短手柄、大体对称地安装在锅身两侧上。限压阀底部套有自动清理防堵罩22,锅内还可设有蒸箅1附件,锅盖边沿还开有超压泄汽窗16。
其工作原理过程如下:当锅盖、锅身扣合处于初始位置时,对压力锅加热时,由于锅盖和锅身之间的密封圈失去密封作用,锅内不能上压;在锅盖、锅身扣合过程,锅身凸牙使偏心轮偏转带动安全板水平向锅盖中心移动,压住自锁阀使之不能上升而失去密封作用,锅内不能上压;只有到锅身和锅盖扣合到位后,偏心轮处于常态位置,弹簧使安全板后移复位,自锁阀在汽压作用下自由上升,通常自锁阀下部装设的密封圈对锅盖进行密封,压力锅才正常上压工作。当压力锅锅压超过某一值处于危险状态时,气压顶开密封垫和压板,大量泄气降压,使压力锅锅压回复到安全状态。
