Pressure-regulating device and pressure-regulating method inside pot and pot

Abstract

The invention provides a pressure-regulating device and a pressure-regulating method inside a pot and the pot. The pressure-regulating device comprises a pressure sensor unit, a treatment unit, a comparing unit and an adjusting unit, wherein the pressure sensor unit is used for acquiring the air pressure value at the position of the pot and acquiring a pressure value inside the pot in real time, the treatment unit is used for calculating the difference between the preset air pressure value and the air pressure value obtained by the pressure sensor unit, so as to obtain a first difference value, and calculating the difference between the pressure value and the air pressure value acquired by the pressure sensor unit so as to obtain a second difference value, the comparing unit is used for comparing the first difference value and the second difference value to obtain a comparison result; and the adjusting unit is used for adjusting the pressure value inside the pot according to the comparison result of the comparing unit, so as to control the difference value between the pressure value inside the pot and the preset air pressure value within the preset range. With the adoption of the technical scheme, the pressure inside the pot can be automatically adjusted so that the pressure value inside the pot is maintained on a balance point.

Description

Technical field [0001] The present invention relates to the technical field of electric rice cookers, in particular to a pressure regulating device in a pot, a pressure regulating method in a pot, and a pot. Background technique [0002] The common rice cookers on the market are mainly divided into ordinary rice cookers and electric pressure cookers. As the altitude increases, the atmospheric pressure gradually decreases, and the boiling point of water also decreases. Therefore, ordinary rice cookers cannot cook rice due to the drop in the boiling point of water in a high altitude environment; and in this environment The electric pressure cooker has obvious advantages. It can keep the air pressure in the pot above the normal pressure, so that the rice can be steamed, but the electric pressure cooker cannot maintain the pressure value in the pot at the equilibrium point, that is, it cannot achieve constant boiling point heating. food. [0003] Therefore, how to adjust the pressure...

Problems solved by technology

As the altitude increases, the atmospheric pressure gradually decreases, and the boiling point of water decreases accordingly, so ordinary rice cookers cannot cook rice due to the decrease in the boiling point of water in an environment with high altitude; The electric pressure cooker has obvious advantages. It can keep the air pressure in the pot above normal pressure, so that the rice can be steamed. However, the electric pressure cooker cannot maintain the pressure value in the pot at the equilibrium point, that is, it cannot achieve constant boiling point heating. food
