The pressure cooker usually has a size of 18-32cm, and the common sizes are 18cm, 20cm, 22cm, 24cm, 26cm and so on. The size of the pressure cooker refers to the size of the inner diameter of the boiler, which is generally selected according to the number of people in the family. For example, a family with 1-2 people can choose a pressure cooker with an inner diameter of 18cm and a capacity of 3L. Families with 2-3 people can choose a pressure cooker with an inner diameter of 20cm and a capacity of 4L. Families with 3-5 people can choose a pressure cooker with a capacity of 22cm and 5L, etc.
Second, what should I pay attention to when choosing a pressure cooker?
1, when choosing a pressure cooker, we should consider the number of people in the family. If the family has a small population, we can choose a small-sized pressure cooker, and if the family has a large population, we should choose a large-sized pressure cooker. For example, a two-person family can choose a 4L pressure cooker, and a three-person family can choose a 5L pressure cooker. When choosing a pressure cooker, if 20cm and 22cm pressure cookers are suitable, everyone should try to choose a large pressure cooker.
2. When buying the pressure cooker, we can check whether the product's trademark, specifications, manufacturer's address, implementation standards and other related information are complete, and whether the pressure cooker has a certificate of approval, warranty, instructions for use, etc. You also need to carefully check whether there is any coating loss, scratches, bumps and other damage on the pressure cooker body, whether its related accessories are complete and firmly installed, and so on.
3. When purchasing a pressure cooker, everyone should pay special attention to whether the safety performance of the pressure cooker is qualified. For example, the vent hole of the pressure cooker should be smooth. If the vent hole of the pressure cooker is uneven, it is prone to safety accidents such as food blocking the vent hole and explosion of the pressure cooker. When purchasing, we should also pay attention to whether the pressure cooker has pressure control safety devices, pressure relief safety devices, anti-blocking safety devices and so on.
