Problems solved by technology

However, since the temperature sensor adopted is arranged at the bottom of the electric pressure cooker, what it directly senses is the temperature of the heating element at the bottom of the electric pressure cooker, not the temperature of the cooking space, so the air pressure of the cooking space obtained through conversion calculation is inaccurate , affecting the cooking control accuracy

Embodiment 1

[0036] Such as Figure 1-2 As shown, this embodiment relates to an electric pressure cooker, which can be used for cooking different food materials, such as: cooking rice, stewing soup, and the like. As we all know, when using an electric pressure cooker to cook different ingredients, in order to achieve delicious results, the pressure required for cooking different ingredients may be different, and the pressure required for different cooking time stages may also be different. The real-time air pressure in the space is detected, and the state of the electric pressure cooker is controlled according to the detected real-time air pressure indication value, such as: temperature increase, heat preservation, pressure reduction, etc.

[0037] The electric pressure cooker of this embodiment includes a conventional pot cover 1 and a pot body 2 that cooperates with the pot cover 1 to form a cooking space. An inner pot 3 can be placed in the pot body 2, and food materials can be placed i...

Embodiment 2

[0050] Such as Figure 6 As shown, the difference between this embodiment and other embodiments is that in the displacement sensor 4, the follower 43 is the first electrode plate of the variable capacitance C, and the sensing portion 42 is the second electrode plate including the variable capacitance C. oscillator circuit. The oscillator circuit can be used as Figure 5 The RC oscillating circuit shown can also be an LC oscillating circuit. Regardless of whether the RC or LC oscillation circuit is used, the corresponding frequency signal can be obtained, and the frequency signal is the above-mentioned induction signal. Subsequent processing is similar to other embodiments, and will not be repeated here. The RC or LC oscillating circuit with variable capacitance is used to sense the real-time relative position between the follower part 43 and the sensing part 42 , which can reduce the manufacturing cost of the displacement sensor 4 .

Abstract

The invention relates to a displacement sensor, an electric pressure cooker and a cooking control method. A feeling body arranged on the displacement sensor is deformed through medium pressure changesof the feeling body, and drives a following part to move, the relative position between the following part and an induction part is changed accordingly, the induction body can induce the real-time relative position between the induction part and the following part, and real-time medium pressure of the induction body is further reflected. In this way, changes of the relative positions between theinduction part and the following part are related to changes of medium pressure of the induction body, and the obtained real-time medium pressure indicator value accuracy is high after calculation.

Description

technical field [0001] The invention relates to the field of sensor technology, in particular to a displacement sensor, an electric pressure cooker and a cooking control method. Background technique [0002] Electric pressure cooker is an upgraded product of traditional pressure cooker and electric rice cooker. It combines the advantages of traditional pressure cooker and electric rice cooker, can solve the safety problem of traditional pressure cooker, and has high thermal efficiency. [0003] The air pressure in the cooking space in an electric pressure cooker is decisive for the taste of the resulting food. Usually, the temperature in the electric pressure cooker is detected first, and then the detected temperature is converted and calculated to obtain the air pressure in the cooking space. However, since the temperature sensor adopted is arranged at the bottom of the electric pressure cooker, what it directly senses is the temperature of the heating element at the botto...
