Electric pressure cooker using angular displacement sensing device

Abstract

The invention relates to the technical field of household appliances in a kitchen, in particular to an electric pressure cooking saucepan adopting an angular displacement sensor. The electric pressure cooking saucepan comprises an inner pot, an outer pot, a pot cover and a shell; the bottom of the inner pot is provided with a heating disk of which the bottom is fixed with a post rod transmitting the pressure displacement of the inner pot; the post rod is connected with the angular displacement sensor arranged on the bottom of the outer pot or the shell through a transmission device; the transmission device having the functions of transforming the up and down displacement of the post rod into a rotation angle and transmitting the rotation angle to the angular displacement sensor is arranged on the bottom of the outer pot or the shell; the angular displacement sensor outputs different electrical signals to a control circuit according to received angular displacement signals; and the control circuit controls the heating disk connected with the angular displacement sensor to adjust the pressure in the inner pot according to different electrical signals sent by the angular displacementsensor. Therefore, the electric pressure cooking saucepan has the characteristics of novel structure and more precise measurement and control of the pressure of the inner pot.

Description

technical field [0001] The invention relates to the technical field of household kitchen appliances for daily life, in particular to an electric pressure cooker using an angular displacement sensing device. Background technique [0002] With the improvement of people's living standards, more and more household appliances have entered thousands of households. Nowadays, electric pressure cookers are widely used by people because of their convenience and speed. In electric pressure cookers, how to accurately measure the inner pot Pressure to better control the pressure has become the key technology of this product. The usual electric pressure cooker fixes the ejector rod on the heating plate at the bottom of the inner pot, and directly measures the vertical displacement of the ejector rod through sensors such as capacitance and voltage to determine the pressure of the inner pot. However, because the vertical displacement of the ejector rod is very small, the data obtained by di...

[0002] With the improvement of people's living standards, more and more household appliances have entered thousands of households. Nowadays, electric pressure cookers are widely used by people because of their convenience and speed. In electric pressure cookers, how to accurately measure the inner pot Pressure to better control the pressure has become the key technology of this product. The usual electric pressure cooker fixes the ejector rod on the heating plate at the bottom of the inner pot, and directly measures the vertical displacement of the ejector rod through sensors such as capacitance and voltage to determine the pressure of the inner pot. However, since the vertical displacement of the ejector rod is very small, the data obtained by direct measurement tends to have large errors. Therefore, how to improve this structure to measure the pressure of the inner pot more accurately and better control the pressure has become an area to be improved.
