pressure cooking equipment

Abstract

The invention provides pressure cooking equipment. The pressure cooking equipment comprises an inner pot, an inner cover, a pot cover, at least one through hole, a magnetic pulse generator, an audio receiver and as signal processor, wherein the inner cover and the pot cover are movably connected; the pot cover is buckled on the inner pot; the at least one through hole is formed in the inner cover;the magnetic pulse generator is arranged on the inner cover and is used for generating a first change magnetic field to ensure that the pot cover undergoes electromagnetic induction under the actionof the first change magnetic field so as to generate a second change magnetic field; the pot cover vibrates under the action of pressure in the first change magnetic field, the second change magneticfield and the inner pot so as to generate an audio signal; the audio receiver is arranged on the inner cover and is used for receiving the audio signal; and the signal processor is connected with theaudio receiver and is used for determining a pressure value in the inner pot according to the audio signal after receiving the audio signal sent by the audio receiver. According to the technical scheme, correct non-contact measurement of pressure in the inner pot of the pressure cooking equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to pressure cooking equipment. Background technique [0002] At present, pressure cooking equipment, such as an electric pressure cooker, mainly includes: (1) installing a pressure switch at the bottom of the outer pot of the pressure cooking equipment, and then controlling the pressure cooking by detecting the displacement of the heating plate of the pressure cooking equipment; The on-off of the heating circuit of the equipment, but this method cannot realize the continuous detection of the pressure in the inner pot of the pressure cooking equipment; (2) Install a temperature sensor in the upper cover of the pressure cooking equipment, and measure the temperature in the inner pot , and then convert the measured temperature into the pressure in the inner pot, but this method ignores that the pressure in the inner pot is not only related to the temperature in ...
