The appointment time of the electric pressure cooker has nothing to do with the pressure in the cooker, and the appointment function is to complete the function after the "appointment time".

The optional pressure maintaining function of electric pressure cooker is mainly set for the change of taste. Optional pressure maintenance means that after the function is completed, there is still pressure in the pot, and the pressure cooker will naturally cool slowly with the ambient temperature, and the pressure in the pot will decrease with the temperature drop.

Extended data:

The choice of electric pressure cooker can be decided according to personal preference. Mechanical electric pressure cooker and microcomputer electric pressure cooker have different control methods, but the use effect is exactly the same. The former is complicated to operate, while the latter is convenient and intuitive, but the price is higher.

When buying electric pressure cookers, people should be considered. Families with 2-3 people choose 4 liters, families with 3-5 people choose 5 liters, and families with more than 6 people choose 6 liters or 8 liters.

In terms of performance, it is important to check whether the contact between the inner pot and the electric heating plate is good, whether the power supply and heating are normal, and whether the function switch and the touch button are normal. The rotary regulator and timer should be able to move freely, and the heating and insulation indicator lights should be turned on and off accordingly.
