Combine accompanying drawing below by detailed description of the invention to be described in further detail the application.
Refer to Fig. 1, the application provides a kind of electric pressure cooker, including pressure detection circuit, specifically, this pressure detecting electricity Road includes: the 1st, the magnetic resistance for output detections signal is provided with magnetisable material and triggers the float 2 that magnetic resistance 1 produces induced signal, And be connected with magnetic resistance 1 to sense float gained induced signal according to magnetic resistance 1, it is judged that the control core with pot external pressure relation in pot Piece 3.
In the present embodiment, magnetic resistance 1 is connected with control chip 3 by a current-limiting resistance R.Magnetic resistance 1 one end and control chip 3 Being connected, the other end is grounded.
General, above-mentioned control chip 3 can be PLC control chip or FPGA control chip etc..And magnetisable material can be magnetic Iron or magnetite.
In the present embodiment, float 2 and magnetic resistance 1 interval are arranged, and due to hypertelorism, magnetic resistance 1 cannot sense float The magnetic field that magnetisable material in 2 produces, then magnetic resistance 1 is off state, during the use of electric pressure cooking saucepan, works as Voltage force When the pot inner pressure of pot is more than pot external pressure namely is more than ambient pressure environment, pot inner pressure produces thrust and promotes float 2 close Magnetic resistance 1, when float 2 is close to magnetic resistance 1 certain distance, magnetic resistance 1 senses the magnetic that the magnetisable material in float 2 produces , then magnetic resistance 1 turns on, and now, magnetic resistance 1 forms loop, the then A near magnetic resistance 1 first end with control chip 3 and the earth A low level signal is exported to control chip 3 on point;When the pot inner pressure of electric pressure cooking saucepan is decreased to equal with pot external pressure, Then pot inner pressure cannot produce thrust to promote float 2, then float 2 cannot sense in float 2 away from magnetic resistance 1, magnetic resistance 1 The magnetic field that magnetisable material produces, then magnetic resistance 1 turns off, and now, magnetic resistance 1 cannot form loop with control chip 3 and the earth, then On the A point of magnetic resistance 1 first end, output one high level signal is to control chip 3;Control chip 3 exports according to A point Low and high level signal judges the pot inner pressure of electric pressure cooking saucepan and the magnitude relationship of pot external pressure, when control chip 3 receives A point During the high level signal exporting, then judge that the pot inner pressure of now electric pressure cooking saucepan is equal with pot external pressure;When control chip 3 connects When receiving the low level signal of A point output, then judge that the pot inner pressure of now electric pressure cooking saucepan is more than pot external pressure;Thus, control Chip 3 can make corresponding operation according to the pot inner pressure size of the electric pressure cooking saucepan judged, very in time, and accurately.
First end of magnetic resistance 1 is connected with control chip 3 through current-limiting resistance R, and current-limiting resistance R acts primarily as the effect of current limliting, With avoid because of magnetic resistance 1 turn on when, the loop that magnetic resistance 1 and control chip 3 are formed powers on and flows through big, and causes magnetic resistance 1 and control The situation that chip 3 damages because of larger current, enhances stability and the reliability of circuit, can protect well magnetic resistance 1 and Control chip 3.
So, owing to merely with magnetic resistance and be provided with the float of magnetisable material and carry out pressure detecting, structure is very simple, body Long-pending little, and reaction is fast, can promptly and accurately detect pot inner pressure, reliability is high, long working life.
It should be added that, position being set and distance is set can enter according to actual conditions of above-mentioned float 2 and magnetic resistance 1 Row design.And magnetic resistance 1 one end can be earth-free, and can receive on certain terminal in control chip 3.
In the description of this specification, reference term " embodiment ", " some embodiments ", " an enforcement The description of example ", " some embodiments ", " example ", " specific example " or " some examples " etc. means to combine this embodiment or example The specific features, structure, material or the feature that describe are contained at least one embodiment or the example of the application.In this explanation In book, identical embodiment or example are not necessarily referring to the schematic representation of above-mentioned term.And, the concrete spy of description Levy, structure, material or feature can combine in any one or more embodiment or example in an appropriate manner.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to assert this Shen Being embodied as please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off On the premise of the application conceives, some simple deduction or replace can also be made.
