Specific embodiment

It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

In the prior art, during screwing pot cover, the operation bite of pot cover is rotated, user experience is poor.

Inventor by long-term research and analysis, the reason of having obtained the generation above problem:

In the ideal situation, there are gaps between pot tooth and corresponding lid teeth, and there is also gaps between liner and retainer.No Crossing is influenced by factors such as the precision of assembly technology and part, is formed between inner pot cover and interior pot and is unevenly contacted, leads to inner pot cover It is unbalanced to be lifted so that some in inner pot cover is close to retainer, the corresponding part in such retainer also with liner Be close to, i.e., inside in the circumferential direction of pot, pot tooth corresponding lid teeth in part is abutted, and the regional area of retainer is abutted with liner, Upper frictional force is generated in this way when rotating pot cover, between liner and retainer, lower frictional force is generated between pot tooth and lid teeth, i.e., mutually Lower frictional force is generated between the pot tooth and lid teeth of abutting, while upper frictional force is generated between the retainer and liner mutually abutted, Under the collective effect of upper frictional force and lower frictional force, the operation bite of pot cover is rotated, will appear when serious can not unscrew pot The phenomenon that lid.

When electric pressure cooking saucepan work, pot cover has been screwed in place.Kettle temperature rises at this time, between interior pot and inner pot cover Sealing ring is heated, and volume increases.The air pressure in sealing ring and interior pot deformed at this time applies to inner pot cover towards liner Thrust, under the action of thrust, inner pot cover drives retainer mobile towards liner.When inner pot cover and retainer move a certain distance Afterwards, the lid teeth of retainer is abutted with the pot tooth of interior pot, and retainer is abutted with liner.Temperature when electric pressure cooking saucepan stops working, in pot Return to normal with air pressure, the volume-diminished of the sealing ring expanded at this time, and air pressure disappears to the active force of inner pot cover, interior pot Covering under the gravity of itself has the tendency that moving towards interior pot.When sealing ring reduces, by the material and knot of sealing ring The influence of the factors such as structure, the diminution of the volume of sealing ring is simultaneously uneven, i.e., some in sealing ring has restored original volume, The other parts of sealing ring are not restored, and still maintain state when expansion.In the position expanded in sealing ring in this way heads on Pot cover.Inside in the circumferential direction of pot, since the partial region in inner pot cover is headed on by sealing ring, the region of inner pot cover could not restore Original position.In this way, the corresponding pot tooth in the region of inner pot cover and lid teeth still abutting contact, retainer and liner remain on to It connects, rotates pot cover at this time, above-mentioned upper frictional force and lower frictional force can be generated, make the operation bite for rotating pot cover.

Currently, to solve the above-mentioned problems, generally using several following solutions:

1, the gap in increasing between pot and inner pot cover, in this way in closing lid, sealing ring jacks up the distance of inner pot cover upwards Reduce, there are gaps between the lid teeth and corresponding pot tooth on retainer, and there is also gaps between retainer and liner, are rotating When pot cover, above-mentioned upper frictional force and lower frictional force will not be generated.The gap but increased between sealing ring and interior pot will lead to The air leakage of product increases, and pot inner pressure does not reach requirement, and influences the performance of complete machine.

2, the hardness for reducing sealing ring weakens effect of the sealing ring to inner pot cover in this way in closing lid, and sealing ring pushes up upwards The distance for playing inner pot cover reduces, and there are gaps between the corresponding pot tooth of lid teeth on retainer, also deposits between retainer and liner In gap, in this way when rotating pot cover, above-mentioned upper frictional force and lower frictional force will not be generated.But which also results in increasing Add air leakage, pot inner pressure does not reach requirement, and influences the performance of complete machine.

3, the height for increasing the lid teeth on retainer, in this way in closing lid, lid teeth and corresponding pot tooth on retainer it Between there are gaps, when screwing pot cover, when will not generate above-mentioned lower frictional force, but screw pot cover, still can exist above-mentioned Upper frictional force, rotate the operation bite of pot cover.

To solve the above-mentioned problems, inventors herein propose it is below the technical solution of the utility model includes:

As shown in Figures 1 to 4, the utility model provides a kind of cooking apparatus.The cooking apparatus of the present embodiment includes pot Body 10, pot cover 20 and ejection position limiting structure 50.Pot body 10 is provided with pot tooth 111 to hold food to be cooked in pot body；Pot cover 20 are arranged in pot body 10, and the lid teeth 231 cooperated with pot tooth 111 is provided on pot cover 20, and pot cover 20 includes cover assembly and sets The inner pot cover 22 below cover assembly is set, lid teeth 231 is arranged on the retainer 23 between cover assembly and inner pot cover 22；Ejection Position limiting structure 50 is arranged between cover assembly and inner pot cover 22, the range that ejection position limiting structure 50 moves upwards inner pot cover 22 It is defined so as to have interval between the lid teeth 231 being correspondingly arranged and pot tooth 111.

In the present embodiment, ejection position limiting structure 50 be arranged between cover assembly and inner pot cover 22, when inner pot cover 22 upward When cap assemblies move, after the mobile pre-determined distance of inner pot cover 22, blocking of the inner pot cover 22 by ejection position limiting structure 50, and ejection limits Blocking of the bit architecture 50 by cover assembly, such inner pot cover 22 cannot be moved to cover assembly, i.e., inner pot cover 22 can only be upward Mobile preset distance, pot tooth 111 and corresponding lid when inner pot cover 22 is moved upwards up to extreme position, in pot body 10 There is interval between tooth 231, is not contacted between the lid teeth 231 being correspondingly arranged and pot tooth 111, during screwing pot cover 20, Frictional force is not generated between lid teeth 231 and pot tooth 111, screwing for pot cover 20 is smooth, better user experience.

In other alternate embodiments, retainer 23 can not also be set in pot body, in this way, directly lid teeth 231 is arranged On inner pot cover 22.Ejection position limiting structure 50 is arranged between cover assembly and inner pot cover 22, and ejection position limiting structure 50 is to inner pot cover 22 ranges moved upwards are defined so as to have interval between the lid teeth 231 being correspondingly arranged and pot tooth 111.In this way, pushing away Under the barrier effect for pushing up position limiting structure 50, inner pot cover 22 can only move up preset distance, when inner pot cover 22 is moved upwards up to When extreme position, have interval between the pot tooth 111 and corresponding lid teeth 231 in pot body 10, the lid teeth 231 being correspondingly arranged with It is not contacted between pot tooth 111, during screwing pot cover 20, does not generate frictional force, pot between lid teeth 231 and pot tooth 111 Screwing for lid 20 is smooth, better user experience.
