The following description will be given taking as an example the sliding movement of the transmission frame 1:

the first guide structure comprises a first guide part and a second guide part, the first guide part extends from the edge of the cooking container to the second guide part and is butted (namely the first guide part and the second guide part are directly connected without other connecting structures) with the second guide part, the second guide part is parallel to the sliding direction of the transmission frame, and the pressure relief driving part moves along the guide direction of the first guide part.

Wherein, first guide part is along extending to the direction at culinary art courage center from culinary art courage edge, and during encapsulated situation, the first end of pressure release bobble push rod 2 is in the tip near culinary art courage edge, and when the driving frame 1 removed, under the guide of first guide part, pressure release bobble push rod 2 removed to the direction near the central district of culinary art courage to promote pressure release bobble 21 and remove the closure to the pressure release mouth, make cooking utensil pressure release.

Install in first guide structure based on the first end of pressure release driving piece, move along the extending direction of first guide part, at the pressure release in-process, pressure release bobble 21 need keep deviating the state of pressure release mouth, when avoiding the continuous motion of driving frame 1, pressure release bobble push rod 2 moves thereupon, first guide structure still includes the second guide part, the second guide part plays the effect of stepping down, the butt joint of second guide part is close to the one end at culinary art courage center in first guide part, and the route intercommunication of first guide part and second guide part. When pressure release bobble push rod 2 was located the tip that first guide part is close to the culinary art courage center, driving frame 1 continued to move, and pressure release bobble push rod 2 gets into second guide part, and pressure release bobble push rod 2 no longer with driving frame 1 simultaneous movement, avoids driving frame 1 motion to influence the pressure release process.

Preferably, the first guide is provided as a first channel 31 and the second guide is provided as a second channel 32.

Specifically, when the cooking appliance is sealed, the first guide bar 4 is located at an end of the first channel 31 remote from the second channel 32. When the sealing is released, the first guide rod 4 moves towards the direction close to the second channel 32 along the first channel 31, the first guide rod 4 drives the small pressure relief ball push rod 2 to push the small pressure relief ball 21, and the pressure relief opening is opened to relieve the pressure; after the pressure relief is finished, the transmission frame 1 continues to slide, the first guide rod 4 does not move along with the first guide rod, the first guide rod and the second guide rod move relatively, namely the second channel 32 slides relative to the pressure relief small ball push rod 2, and therefore the conflict between the static state of the pressure relief small ball push rod 2 and the continuous movement of the transmission frame 1 is solved.

It should be noted that the pressure relief ball push rod 2 is not limited to provide a pushing force to the pressure relief ball 21, and may provide a pulling force as long as the pressure relief ball 21 is driven to deviate from the pressure relief opening.

Cooking utensil pressure release can guarantee the normal clear of culinary art process to and guarantee cooking utensil's security, can not directly uncap behind the pressure release, lock through the hasp between lid and the culinary art courage. The locking mode of the lock catch is various, and the lock catch comprises a manually adjustable lock catch and a mechanically driven lock catch. When the lock catch is in a manually-adjusted structure, the cover can be opened manually after the pressure relief in the cooking utensil is finished; when the lock catch is of a mechanical driving structure, after pressure relief in the cooking appliance is completed, the internal driving structure drives the lock catch to be opened again.

The related design for opening the latch 20 after venting is given below:
