Electric pressure cooker automatically regulated by pressure limit values

Abstract

The invention discloses an electric pressure cooker automatically regulated by pressure limit values. The electric pressure cooker comprises a cooker cover, a cooker body, a controller, a motor, a transmission piece assembled on the cooker cover, a pressure regulator, a surface cover, an air exhaust pipe and a valve body sleeved on the air exhaust pipe, and is characterized in that, the pressure regulator capable of moving along the axial direction of the air exhaust pipe is movably sleeved at the lower part of the valve body in the air exhaust pipe; the pressure regulator and the motor are connected and interacted through the transmission piece. According to the electric pressure cooker of the invention embodiment, the high-low pressure judging selection of the pressure limit values of the electric pressure cooker and the random switching of the pressure limit values when cooking are automatically realized through cooking functions chosen by consumers, so that the cooking performance of the conventional electric pressure cooker is improved and modified by intelligent methods, and cooked foods have better color, aroma and taste and higher nutritive value.

Description

technical field [0001] The invention relates to the technical field of electric pressure cooker, in particular to an electric pressure cooker whose pressure limit value can be automatically adjusted regardless of the connection mode of the pot cover and the pot body. Background technique [0002] The working pressure of the electric pressure cooker with elastic structure (the pressure when the pressure switch is turned off and the power is turned on) has been set at the factory. In addition to the effect of the thermal inertia of the electric heating plate, no matter what kind of food is cooked, there is only one cooking pressure. , and the working process is carried out without exhaust and without boiling. Therefore, its cooking performance has relatively large defects. For example, when stewing food, the separation of soup materials is clear, and the vision and taste are far inferior to those of conventional utensils. As a result, the lack of cooking is more prominent. Mos...

Problems solved by technology

[0002] The working pressure of the electric pressure cooker with elastic structure (the pressure when the pressure switch is turned off and the power is turned on) has been set at the factory. In addition to the effect of the thermal inertia of the electric heating plate, no matter what kind of food is cooked, there is only one cooking pressure. , and the working process is carried out without exhaust and without boiling. Therefore, its cooking performance has relatively large defects. For example, when stewing food, the separation of soup materials is clear, and the vision and taste are far inferior to those of conventional utensils. As a result, the lack of cooking is more prominent. Most of the time, the cooked rice will turn black due to the "Maillard reaction". , the middle is thin and rotten with three different effects, the bad result is that the rice has different degrees of rawness

[0003] In order to improve the cooking performance defects caused by the single working pressure of the existing electric pressure cooker and cooking without boiling, the patent application number is 201210153760.7 for "electric pressure cooker with automatic switchable pressure limit" and the patent for "adjustable pressure limit value" with application number 201210168683.2 "Electric pressure cooker" patent, application number 201210168696.X "Electric pressure cooker with adjustable pressure limit" patent, with the lowest cost and the most concise technical solution, realizes the high and low pressure compatibility of the electric pressure cooker and low-pressure boiling cooking. The performance of cooking rice has been improved, but a second manual adjustment is required, which not only increases the operation action, but also easily leads to wrong operation.
