Description

烹饪锅及其锅盖Cooking pot and its lid

本申请要求于2019年11月05日提交的申请号为2019110730268，发明名称为“烹饪锅及其锅盖”的中国专利申请的优先权，其通过引用方式全部并入本申请。This application claims the priority of the Chinese patent application filed on November 05, 2019 with the application number 2019110730268 and the invention title "Cooking Pot and Its Lid", which is fully incorporated into this application by reference.

【技术领域】【Technical Field】

本发明涉及烹饪厨具技术领域，特别涉及一种烹饪锅及其锅盖。The invention relates to the technical field of cooking utensils, in particular to a cooking pot and its lid.

【背景技术】【Background technique】

压力厨具通过液体在较高气压下沸点会提升这一物理现象，对水施加压力，使水可以达到较高温度而不沸腾，以加快炖煮食物的速度；锅内液体受热转成水蒸气，利用密封的锅把水蒸气保留在锅里，空气会因为加热而产生高压，从而可以提升液体的沸点。Pressure cooking utensils will increase this physical phenomenon through the boiling point of liquid at higher pressure. Pressure is applied to water so that the water can reach a higher temperature without boiling, so as to speed up the speed of stewing food; the liquid in the pot turns into water vapor when heated. Use a sealed pot to retain water vapor in the pot, and the air will generate high pressure due to heating, which can increase the boiling point of the liquid.

由于锅内有高压存在，因而锅盖与锅体的扣合对防止高压厨具***起到至关重要的作用。目前主流产品的锅盖与锅体的配合是通过锅盖上的锁扣与锅体上的锅牙相互扣合来承压的，承压的效果较好，但是动作较为繁琐：首先合盖时锅盖要对准锅体，避免锁扣与锅牙干涉；扣上锅盖后，旋转锁扣使其与锅牙重合。开盖则是旋转锁扣使锁扣与锅牙错位，然后提起锅盖，完成开盖动作。Due to the presence of high pressure in the pot, the buckling of the lid and the pot body plays a vital role in preventing the explosion of high-pressure cookware. At present, the cooperation between the lid and the pot body of mainstream products is pressure-bearing through the lock on the lid and the teeth on the pot body. The pressure-bearing effect is better, but the action is more cumbersome: first, when closing the lid The lid should be aligned with the pot body to avoid interference between the lock and the teeth; after closing the lid, rotate the lock so that it coincides with the teeth. To open the lid, the lock is rotated to make the lock and the pot teeth misaligned, and then the lid is lifted to complete the opening action.

The pot cover 100 further includes an upper pressure protection member 60 movably arranged on the lid body 10, and the upper pressure protection member 60 is used to limit the telescopic movement of the lock pin 30 under the action of the pressure in the pot body. In this embodiment, when there is pressure in the pot, the upper pressure protector 60 restricts the telescopic movement of the lock pin 30 under the action of the pressure in the pot, which can prevent the user from misoperation and open the lid when there is pressure in the pot. 100, thereby improving the safety performance of the cooking pot.

其中，在一实施例中，如图1和图5所示，盖体10上开设有安装孔18，锁销件30上开设有锁定孔36，上压保护件60的第一部分穿设于锁定孔36内，上压保护件60的第二部分穿设于安装孔18内，并吊挂在盖体10上，上压保护件60的第二部分在锅体内压力的作用下上升至锁定孔36，进而对锁销件30的伸缩运动进行限制。Among them, in one embodiment, as shown in FIGS. 1 and 5, the cover 10 is provided with a mounting hole 18, the lock pin 30 is provided with a locking hole 36, and the first part of the upper pressure protection member 60 penetrates through the lock In the hole 36, the second part of the upper pressure protector 60 is inserted into the mounting hole 18 and hung on the cover 10, and the second part of the upper pressure protector 60 rises to the locking hole under the action of the pressure in the pot. 36, further restricting the telescopic movement of the lock pin 30.

具体地，当锅体内无压力时，上压保护件60吊挂在盖体10上，锁销件30可以在联动机构40的带动下相对盖体10移动。当锅体内有压力时，上压保护件60在锅体内压力的作用下上升运动，以使第二部分插置在锁定孔36内，当用户提拉手柄20，使得锁销件30有向内收缩的趋势时，上压保护件60的第二部分会抵接于锁销件30，以限制锁销件30收缩进行解锁操作，进而提升产品的安全性能。Specifically, when there is no pressure in the pot, the upper pressure protector 60 is hung on the cover 10, and the lock pin 30 can move relative to the cover 10 under the driving of the linkage mechanism 40. When there is pressure in the pot, the upper pressure protector 60 moves upward under the action of the pressure in the pot, so that the second part is inserted in the locking hole 36. When the user pulls the handle 20, the lock pin 30 is inward. In the shrinking trend, the second part of the upper pressure protection member 60 will abut against the lock pin 30 to limit the lock pin 30 from contracting for unlocking operation, thereby improving the safety performance of the product.

进一步地，上压保护件60的第一部分的外壁与锁定孔36的内壁之间的活动余量大于或等于锁销件30的最大位移量，上压保护件60的第二部分的外壁与锁定孔36的内壁之间的活动余量设置成小于锁销件30进行解锁所需的位移量。Further, the movable margin between the outer wall of the first part of the upper pressure protector 60 and the inner wall of the locking hole 36 is greater than or equal to the maximum displacement of the lock pin 30, and the outer wall of the second part of the upper pressure protector 60 is locked The movement margin between the inner walls of the hole 36 is set to be smaller than the displacement amount required for the lock pin 30 to unlock.

具体地，上压保护件60的第一部分的外壁与锁定孔36的内壁之间的活动余量指的是：上压保护件60的第一部分穿设在锁定孔36内时，锁销件30可以相对上压保护件60移动的最大距离。锁销件30的最大位移量指的是：锁销件30在联动机构40的带动下的最大移动距离。通过设置锁销件30相对上压保护件60移动的最大距离大于或等于锁销件30的最大位移量，可以避免锁销件30移动的过程中，吊挂在盖体10上的上压保护件60对锁销件30造成干涉。Specifically, the movement margin between the outer wall of the first part of the upper pressure protector 60 and the inner wall of the locking hole 36 refers to: when the first part of the upper pressure protector 60 penetrates the locking hole 36, the lock pin 30 The maximum distance that can be moved relative to the upper pressure protector 60. The maximum displacement of the locking pin 30 refers to the maximum moving distance of the locking pin 30 driven by the linkage mechanism 40. By setting the maximum movement distance of the lock pin 30 relative to the upper pressure protection member 60 to be greater than or equal to the maximum displacement of the lock pin 30, the upper pressure protection hung on the cover 10 during the movement of the lock pin 30 can be avoided The member 60 interferes with the lock pin member 30.

上压保护件60的第二部分的外壁与锁定孔36的内壁之间的活动余量指的是：上压保护件60的第二部分穿设在锁定孔36内时，锁销件30可以相对上压保护件60移动的最大距离。锁销件30解锁所需的位移量指的是：锁销件30相对锅体锁合时的位置与锁销件30刚好相对锅体解锁时的位置之间的距离。通过将上压保护件60的第二部分的外壁与锁定孔36的内壁之间的活动余量设置成小于锁销件30进行解锁所需的位移量，可以避免上压保护件60的第二部分穿设于锁定孔36内时，锁销件30相对锅体解锁。The movement margin between the outer wall of the second part of the upper pressure protector 60 and the inner wall of the locking hole 36 refers to: when the second part of the upper pressure protector 60 is inserted into the locking hole 36, the lock pin 30 can The maximum distance relative to the upper pressure protector 60 to move. The amount of displacement required for unlocking of the lock pin 30 refers to the distance between the position of the lock pin 30 when the lock pin 30 is locked relative to the pot body and the position of the lock pin 30 just when the lock pin 30 is unlocked relative to the pot body. By setting the movement margin between the outer wall of the second part of the upper pressure protector 60 and the inner wall of the locking hole 36 to be less than the displacement required for the lock pin 30 to unlock, the second part of the upper pressure protector 60 can be avoided. When partially inserted into the locking hole 36, the locking pin 30 is unlocked relative to the pot body.

其中，上压保护件60可以设置为一体结构，也可以设置成包括至少两个元件，本发明实施例不做具体限定。在本实施例中，如图5和图6所示，图6是图5中的上压保护件的剖视结构示意图。上压保护件60可以包括活动套62、指示棒64和抵接件66。活动套62穿设于安装孔18内，指示棒64穿设于锁定孔36内，并与活动套62连接，指示棒64上设置有一环形凸缘642，环形凸缘642的外径大于安装孔18的直径，以将活动套62吊挂在盖体10上，抵接件66与活动套62连接，且抵接件66的外径大于安装孔18的直径，其中，在锅体内压力的作用下，活动套62上升至锁定孔36内，进而对锁销件30的伸缩运动进行限制，同时抵接件66与盖体10形成抵接，进而密封安装孔18。Wherein, the upper pressure protector 60 may be provided as an integral structure, or may be provided as including at least two elements, which is not specifically limited in the embodiment of the present invention.

Bottom, the movable sleeve 62 rises into the locking hole 36, thereby restricting the telescopic movement of the locking pin 30, and at the same time, the abutting member 66 abuts against the cover body 10, thereby sealing the mounting hole 18.

具体地，指示棒64的一端与活动套62连接，指示棒64的另一端可在锅体内压力的作用下伸出锅盖100，以用于指示锅体内存在压力。指示棒64上的环形凸缘642的外径大于安装孔18的直径，进而可以将上压保护件60吊挂在盖体10上。抵接件66设置于盖体10背离指示棒64的一侧，用于在活动套62上升时，抵接于盖体10的内侧，防止上压保护件60从安装孔18中脱出。Specifically, one end of the indicator rod 64 is connected to the movable sleeve 62, and the other end of the indicator rod 64 can be extended out of the pot cover 100 under the action of the pressure in the pot to indicate the presence of pressure in the pot. The outer diameter of the annular flange 642 on the indicator rod 64 is larger than the diameter of the mounting hole 18, so that the upper pressure protector 60 can be hung on the cover 10. The abutting member 66 is disposed on the side of the cover body 10 away from the indicator bar 64 for abutting against the inner side of the cover body 10 when the movable sleeve 62 rises to prevent the upper pressure protector 60 from falling out of the mounting hole 18.
