Need using complicated logical sum program, it is possible thereby to make that the decision procedure of the pressure control procedure of electric pressure cooking saucepan 1 is simpler, control
Process processed is more directly reliable, avoids to report an error caused by the logic complexity of multiple decision and takes place frequently.
Further, can be so as to because the pressure control procedure of electric pressure cooking saucepan 1 need not use complicated logical sum program
In saving the structure of running the program, so as to be easy to simplify the overall structure of electric pressure cooking saucepan 1, reduce electric pressure cooking saucepan 1 into
This, improves the production efficiency of electric pressure cooking saucepan 1.
Therefore, according to the electric pressure cooking saucepan 1 of the utility model embodiment have pressure control structure simple and reliability height etc.
Advantage.
Below with reference to the accompanying drawings electric pressure cooking saucepan 1 according to the utility model specific embodiment is described.
In some specific embodiments of the present utility model, as depicted in figs. 1 and 2, according to the utility model embodiment
Electric pressure cooking saucepan 1 includes pot body 100, pot cover 200, pressure release part 300, drive device 400 and pressure-detecting device 500.
Specifically, drive device 400 is electromagnetic actuator device.Telecommunications so can be passed through in order to pressure-detecting device 500
Number control drive device 400, and because the electromagnetic actuator device response time is short, mechanical wear is small, can so be improved to electricity
The sensitivity of the pot inner pressure of pressure cooker 1 control and accuracy, improve the reliability of the Stress control of electric pressure cooking saucepan 1.
More specifically, as depicted in figs. 1 and 2, drive device 400 includes electromagnet 410 and iron core 420, electromagnet 410
It is located in pot cover 200 and is electrically connected with pressure-detecting device 500.Iron core 420 is promoting the opening pressure relief opening 210 of pressure release part 300
Movably coordinate in electromagnet 410 between vent position and the pressure position for avoiding pressure release part 300.Iron can so be passed through
Core 420 controls pressure release part 300 to be moved between the vent position and the pressure position, to drive pressure release using iron core 420
Part 300 opens or closes pressure relief opening 210.It is possible thereby to be easy to the switching of the function of pressure release part 300, it is easy to 1 pot of internal pressure of electric pressure cooking saucepan
The control of power.
Further, as depicted in figs. 1 and 2, drive device 400 also includes elastic component 430, elastic component 430 respectively with iron
Core 420 is connected with electromagnet 410 and often driving iron core 420 moves to the pressure position, and electromagnet 410 drives iron when being powered
Core 420 overcomes the elastic force of elastic component 430 to be moved to the vent position.So when electric pressure cooking saucepan 1 is cooked, elastic component is utilized
430 elastic force often drives iron core 410 to be moved to the pressure position, iron core 410 is kept avoiding the state of pressure release part 300, energy
Enough ensure that there is certain pressure all the time in electric pressure cooking saucepan 1, be easy to improve the performance of electric pressure cooking saucepan 1, it is logical in electromagnet 410
Electromagnet 410 is set to overcome elastic force to promote the pressure release of pressure release part 300 after electricity, so as to realize the cooking method of variable pressure in pot.
Further, pressure-detecting device 500 and electromagnet 410 are directly connected to by wire.So electric pressure cooking saucepan 1
Pressure control procedure needs not move through circuit board, can not only simplify the structure of Stress control, reduces the cost of electric pressure cooking saucepan 1, carries
The production efficiency of high voltage power pot 1, and can further avoid because signal by multiple decision structure and caused by frequently
Report an error.
Figures 1 and 2 show that according to electric pressure cooking saucepan 1 of the present utility model.As depicted in figs. 1 and 2, pressure release part 300 is ball

On, pressure release part 300 is rollably located in pressure release part locating slot 220.So pressure release part 300 can be made to be slidably fit into pot
In lid 200, pressure release part 300 is positioned using pressure release part locating slot 220, and pressure release part 300 can be avoided in iron core 420
When, pressure release part 300 is voluntarily fallen after rise under gravity to close pressure relief opening 210.Meanwhile if pressure-detecting device 500
Failure, after causing pressure further to raise, pressure release part 300 can be opened by pressure top and realize pressure release, prevent hypertonia and produce
It is dangerous.
Alternatively, as depicted in figs. 1 and 2, pot cover 200 is provided with locating cover 230, locating cover 230 and pressure release part locating slot
220 limit the movable chamber 240 for the activity of pressure release part 300 jointly, and locating cover 230 is provided with the iron core connected with movable chamber 240
Via 231, iron core 420 are adapted to pass through iron core via 231.So pressure release part 300 can be made movably to coordinate in locating cover 230
It is interior, the mobile space of pressure release part 300 is limited using locating cover 230 and pressure release part locating slot 220, avoids pressure release part 300 from departing from and lets out
Casting die locating slot 220.Meanwhile locating cover 230 can ensure iron core provided with iron core via 231 in order to the setting of iron core 420
420 normal work, it is easy to iron core 420 to be contacted with pressure release part 300, consequently facilitating pressure release part 300 realizes the movement of position.
Advantageously, relief port 210 is located at the center of pot cover 200 in the horizontal direction (the arrow in fore-and-aft direction such as Fig. 1
Shown in B).When so pressure rises to certain value in electric pressure cooking saucepan 1, it is ensured that the pot inner pressure of electric pressure cooking saucepan 1 is uniform, is easy to
Improve the culinary art effect of electric pressure cooking saucepan 1.
Specifically, pressure-detecting device 500 is pressure switch, and pressure of the pressure switch in cooking cavity 240 is more than
The conducting and pressure in cooking cavity 240 is disconnected when being less than predetermined value during equal to predetermined value.It can so be opened using the pressure
The pressure in detection electric pressure cooking saucepan 1 is closed, by the conducting and disconnection of the pressure switch, the change of pressure in control voltage power pot 1
Change scope, so as to improve the control ability of pressure in electric pressure cooking saucepan 1, and because pressure switch only exists two kinds of conducting and disconnection
State, it can further avoid judging complicated and causing pressure control program overall more complicated, so as to further be easy to simplify
Pressure control procedure, improve the reliability of Stress control.Further, since the technology of pressure switch is more ripe and simple in construction,
Stress control can be further avoided to fail and influence the normal work of electric pressure cooking saucepan 1.
The pressure control structure of electric pressure cooking saucepan according to the utility model embodiment is described below.It is real according to the utility model
Applying the pressure control structure of the electric pressure cooking saucepan of example includes pressure release part, and the pressure release part is movably arranged at the pot of the electric pressure cooking saucepan
To open or close the pressure relief opening on the pot cover in lid；Drive device, the drive device are located at the pot of the electric pressure cooking saucepan
It is connected in lid and with the pressure release part；For detecting the pressure-detecting device of the Voltage force pot inner pressure, the pressure
Detection means is located on the pot cover of the electric pressure cooking saucepan, and the drive device is more than in the detected value of the pressure-detecting device etc.
Drive the pressure release part to open the pressure relief opening when predetermined value and be less than predetermined value in the detected value of the pressure-detecting device
When drive the pressure release part to close the pressure relief opening.
