Step S114, judges whether the culinary art timing of the cooking process of electric pressure cooking saucepan execution setting reaches setting time, if It is to then follow the steps S116, if it is not, then returning to step S104.

Step S116 terminates operation.

In this embodiment, electric pressure cooking saucepan is on the basis of retaining folding lid self-locking device, the handle and lid that cover on it Setting includes the power sensing device of resistance strain gage and pedestal between body, when user is when operating handle is uncapped, power sensing device It can detecte the size for acting on the power of uncapping on handle, when the power of uncapping detected is greater than the set value, system is determined as It uncaps by force, signal an alert (light or auditory tone cues), meanwhile, optionally, it is dynamic that relevant safeguard protection response can be started Make, such as: stop heating, starting exhaust to be depressured rapidly, so that when user realizes and uncaps maloperation by force, electric pressure cooking saucepan The generation of maloperation, and timely signal an alert can be automatically detected, warning user stops maloperation, meanwhile, it can also make Corresponding safeguard protection response action, such as: stop heating, starting exhaust etc., reduces rapidly pot inner pressure, avoid safe thing Therefore generation.

The technical solution of the utility model is had been described in detail above with reference to the accompanying drawings, which incudes dress by setting power It sets, can accurately detect the power of uncapping on the handle for the upper cover for acting on pressure cooking equipment, and then reach in the power of uncapping and set Warning reminding is carried out when definite value, so that preventing user to be forced through handle during the cooking process opens the upper of pressure cooking equipment Lid, and the steam of the intracorporal high temperature and pressure of the pot of pressure cooking equipment is caused to spray, the danger for causing user to scald, effectively Ground ensure that pressure cooking equipment using safe.
