Clamp are moved in limiting slot 214, since clamp discharge buckling parts 121, pot cover, that is, openable and be detached from pot body 100;Such as Figure 12
Shown, if sealed pot cover again under hot, boss 312 can limit the floating stroke of clamp with 214 bottom surface of limiting slot,
The float cap position under clamp unlocked state is defined, as long as guaranteeing its lower caliper plate when clamp are in float cap position
322 remain to and buckling parts 121 fastens, so that it may avoid the problem that it is hot under can not sealed pot cover, while also avoiding the prior art
It is middle to reset the problem of influencing folding lid feel and closing lid safety using spring auxiliary clamp.
In order to which its lower caliper plate 322 remains to fasten with buckling parts 121 when guaranteeing that clamp are in float cap position, clamp solution
Under lock status, the floating stroke of clamp is limited as H1, under clamp lock state, the floating stroke of clamp is limited as H2, meets H1
< H2.Floating stroke H1 refers to that clamp are floated upwards until boss 312 and 214 bottom surface of limiting slot present position in complete fall
Generated floating distance when offseting, floating stroke H2 refer to that clamp float to lower caliper in present position in complete fall upwards
Plate 322 and buckling parts 121 generated floating distance when fastening;H1 < H2, that is to say, that: unlocked state lower caliper can not float
Position when being fastened to lower caliper plate 322 and buckling parts 121, then blocking under would not also occurring when sealed pot cover 200 under hot
The case where nipper 322 and buckling parts 121 are interfered, and lock state then allows the stroke of clamp floating H2, to guarantee on cooking cavity
Lower caliper plate 322 can be fastened with buckling parts 121 after pressure.
Referring to Fig.1 0, in the present embodiment, before the upper pressure of cooking cavity, between 215 bottom surface of upper surface and escape groove of boss 312
Away from for H4, H4 > H2, that is to say, that the distance of clamp present position floating H4 upwards in complete fall can just make boss 312
Upper surface offsets with 215 bottom surface of escape groove, and in the locked state, only allow the distance of clamp floating H2;Referring to Fig.1 1, due to
H4 > H2, after pressing on cooking cavity, 312 upper surface of boss and escape groove remain a fixed spacing between 215 bottom surface, prevent convex
Platform 312, which compresses cover 212, leads to its deformation.And in the unlocked state, between 214 bottom surface of 312 upper surface of boss and limiting slot
Equipped with gap, clamp normally open and close the contact of 214 bottom surface of Shi Buyu limiting slot, and clamp opening and closing movement is smooth, promote folding feel.
In the present embodiment, the depth of escape groove 215 is greater than the depth of limiting slot 214,215 bottom surface of escape groove and limiting slot
214 bottom surfaces are connected using chamfered transition.Referring to Fig. 9,11, when culinary art terminates to uncap, clamp switch to unlock shape from lock state
During state, the chamfered transition position of 215 bottom surface of escape groove and 214 bottom surface of limiting slot applies pressure on boss 312, to provide clamp
The active force moved downward guarantees clamp reliable reset.
