The difference between pressure cooker and electric pressure cooker is as follows:
1, price
Ordinary pressure cooker is relatively simple, its cost is also relatively low, so there is a certain advantage in terms of plus. If the same brand with the same grade of pressure cooker and electric pressure cooker, then the pressure cooker will be much cheaper. In addition in the process of using, ordinary pressure cooker is with gas, and electric pressure cooker practical electricity.
And the cost of electricity is higher than the cost of gas, so in the later use of the electric pressure cooker incurred costs are relatively high. There is also the fact that if there is a malfunction, the pressure cooker is relatively simple to repair, while the electric pressure cooker has a lot of wiring, maintenance is also more troublesome. So if there is a problem later, in the later maintenance, the electric pressure cooker will also incur a larger cost.
2, safety performance
First of all, the pressure cooker is the use of steam valve to control the pressure of the pot, if the use of pressure cooker in the process of the gas valve and gas valve is blocked, the pressure cooker can continue to heat that may lead to the pot higher than the maximum pressure to withstand the gas pressure, thus triggering an explosion.
If it is an electric pressure cooker, its safety factor will be much higher. Because it is computer-controlled, if there is any malfunction, it will automatically cut off the power. So relatively speaking, it is still the electric pressure cooker safety performance is higher.
3, practicality
Pressure cooker if the gas heating, the heating speed will be faster. In addition, when using the pressure cooker can also continue to use other gas cookers to do different meals.
But the electric pressure cooker is large, high power, if once you turn on the electric pressure cooker, you can not use the kitchen in other electrical equipment. Otherwise, it is easy to appear unstable voltage, short circuit and other phenomena. However, in the process of using or electric pressure cooker is more convenient, with a variety of functions, a key automatic.

Pressure cooker explosion residents kitchen doors and windows were blown away
May 10, 2020 at about 12 o'clock in the afternoon, Hechuan Nanjin Street, a neighborhood of households, is stewing the pressure cooker suddenly exploded, a huge airflow will be blown to the kitchen in a mess, the doors and windows were directly vibration fly, from the third floor fell to the ground floor.
It is understood that normal cooking, the pressure in the pressure cooker is no more than two atmospheres, equivalent to the pressure of a can of Coke. Heating to a certain degree, the pot will rise in air pressure, automatically exhaust from the pressure valve. When the air pressure in the pot continues to rise, the air pressure is vented from the safety valve. When the gas pressure in the pot reaches its limit, the gas is discharged by squeezing the rubber ring.
That is to say, the pressure valve, safety valve and pressure relief tank are the three safety lines of defense for the pressure cooker. When the pressure valve, safety valve or pressure relief tank is blocked, the pressure inside the pot is too high, the pressure continues to rise and exceeds the rated pressure value, it is likely to lead to pressure cooker explosion.
So when using a pressure cooker, be sure to double-check the performance of the lid, gasket, exhaust valve is normal, whether there is a foreign body blocking the situation. At the same time, pay special attention to the pressure cooker is "overdue for service".
Pressure cooker is a certain life, after repeated scrubbing, repeated high-temperature heating, over time will reduce the pressure resistance of the pot, resulting in safety hazards. Therefore, even if the pressure cooker is not often used, once more than the safe use of life, should also stop using.
