Electromagnetic actuator device is coil block, and exhaust steam valve is provided with soft magnetic bodies or permanent magnet, so works as coil groups
Can produce magnetic field during part energising, magnetic field can produce repulsive force or attraction to the soft magnetic bodies on exhaust steam valve or permanent magnet
Power, under the effect of repulsive force or captivation, exhaust steam valve action, steam channel is opened, carries out steam discharge fall
Pressure, so when the size of electrical current or direction difference in coil block, the power in the magnetic field of generation and side
The repulsive force in the magnetic field that soft magnetic bodies in difference, exhaust steam valve or permanent magnet are subject to or captivation size and direction
Different so that the degree that steam channel is opened by exhaust steam valve is different, to realize the control to velocity of exhaust, with
Just at leading portion steam discharge at a slow speed, the back segment speed steam discharge of steam discharge buck stage, thus reach anti-overflow and fast prompt drop simultaneously
The function of pressure.
In second specific embodiment, as shown in Figures 5 to 7, described electromagnetic actuator device is that electromagnetism pushes away
Bar 141.
Further, as shown in Figure 6, described exhaust steam valve 13 is vertically arranged, and may be rotatably mounted at described steaming
In vapour passage, and described exhaust steam valve 13 is provided with plectrum 131；As shown in Figure 6 and Figure 7, described electromagnetism
Push rod 141 is horizontally disposed with, and may act on described plectrum 141, makes described exhaust steam valve 13 rotate.
Further, described exhaust steam valve 13 is additionally provided with reduction torsion spring (not shown).
After entering steam discharge buck stage, electromagnetism push rod is energized so that the push rod of electromagnetism push rod moves, and applies
Thrust, to the plectrum on exhaust steam valve, makes exhaust steam valve rotate, is opened by steam channel, after steam discharge terminates,
Exhaust steam valve, under the effect of reduction torsion spring, automatically resets, and is closed by steam channel；And can be by controlling electromagnetism
The size of the electrical current of push rod and/or direction, control the distance that push rod moves, to realize steam channel
The control of opening degree, and then realize the control to velocity of exhaust, in order to reach anti-overflow and reduction of blood pressure in high-speed simultaneously
Effect.

The control of degree, and then realize the control to velocity of exhaust, in order to reach the anti-overflow and effect of reduction of blood pressure in high-speed simultaneously
Really.
It should be noted that the cooking apparatus described in any of the above-described embodiment of the present invention can be electric pressure cooking saucepan,
Can also be for using other cooking apparatus of pressure cooking, this is no longer going to repeat them.
Below in conjunction with the accompanying drawings, as a example by electric pressure cooking saucepan, illustrate the culinary art that the embodiment of the present invention provides
Utensil carries out the process of steam discharge blood pressure lowering.
The present invention provides a kind of reduction of blood pressure in high-speed method of electric pressure cooking saucepan, as in figure 2 it is shown, described Voltage force
Pot includes upper cover 1 (including cover 10, inner cap 11, pot cover 12) and pot 2, as it is shown on figure 3,
Pot cover 12 top is equipped with gland steam exhauster 15, and gland steam exhauster 15 top is provided with exhaust steam valve 13, pot cover 12 top
It is additionally provided with the electromagnetic actuator device for exhaust steam valve 13；In steam discharge pressure reduction, during beginning, steam in pot
Steam pressure, higher than the spill pressure of exempting from set, is controlled device and is driven by programme-control electromagnetic actuator device
Exhaust steam valve 13 makees continuous micro steam discharge or interval steam discharge action；When the steam pressure in pot is down to exempt to overflow
After pressure, control device control electromagnetic actuator device and drive exhaust steam valve 13 strengthen displacement or extend interval
The persistent period of steam discharge section during steam discharge.
As shown in Figure 4, exhaust steam valve 13 is magnetic force exhaust steam valve, equipped with permanent magnet 130 inside it；Electromagnetism
Driving means is coil block 140, is loaded on the lower section of magnetic force exhaust steam valve, equipped with coil windings inside it
142 and iron core 144, by inputting the current value of different settings to coil assembly 140, magnetic can be controlled
Power exhaust steam valve is under different steam pressures, carry out steam discharge action with different displacements.
Certainly, as shown in Figures 5 to 7, electromagnetic actuator device can also be electromagnetism push rod 141, leans on
Nearly exhaust steam valve 13 is installed, as it is shown in fig. 7, equipped with coil windings 142, iron core 144 and push away inside it
Bar 143.By the current value set to electromagnetism push rod 141 input, exhaust steam valve 13 can be driven to realize
Accomplished continuously or intermittently steam discharge action.
In steam discharge pressure reduction, when in pot steam pressure more than set exempt from spill pressure value (such as:
Time 25kPa), product inputs a less current value to coil block 140 so that it is to exhaust steam valve
The driving force of 13 is more weak, and now exhaust steam valve 13 is with less displacement steam discharge, in preventing electric pressure cooking saucepan
Pressure change is too fast and the excessive pot that causes, it is also possible to by controlling the break-make situation of electric current, the row of driving
Steam valve 13 is made trace and is continued steam discharge or interval steam discharge action (or making the combination of two kinds of steam discharge actions).
In sum, by increasing an electromagnetic actuator device for exhaust steam valve, it is achieved to exhaust steam valve
Control in steam discharge intensity, the temporal active of steam discharge, such that it is able to effectively prevent steam discharge from overflowing, shorten
The time that blood pressure lowering is uncapped.
