As shown in figure 11, the operating principle of the present embodiment is as follows:
When using the pressure cooker, first corresponding food materials will be put into interior pot 9, cover pot cover 7, pot cover 7 is filled safely by closing lid
Set 3 lockings.
By combustion gas over-voltage constant pressure valve 21 define the combustion gas of air pressure by the counterbore in the first connected space, by first into
Gas outlet 1503 is flowed into the second air inlet/outlet 1512, and sprays from ignition tube 12 by ignition tube 12, from ignition tube 12
The combustion gas of ejection is ignited the spark ignition that needle 13 is discharged.Simultaneously as the air pressure in interior pot 9 and the space in pot cover 7 is not
Greatly, compression bar 1508 can not be compressed, so combustion gas can also pass through the first air inlet/outlet 1503 and the first gas outlet 1511, is flowed into
It burns in infrared stove head 5, so combustion gas can internally the bottom of pot 9 be heated, so that the food materials in interior pot 9 heat up.
When infrared stove head 5 is lighted a fire, thermocouple 14 is heated to generate electromotive force, and the electromotive force band moving electromagnetic valve 22 of generation acts, can be with
Combustion gas is supplied, so that infrared burner burns.When accident extinguishing occurs, the voltage of 14 lead end of thermocouple drops rapidly quickly
Low, so that the coil losing electricity in solenoid valve 22, solenoid valve 22 under the action of the spring, cuts off rapidly gas valve body access, prevents from firing
Gas is excessive.
When the air pressure in interior pot 9 is larger, compression bar 1508 by the bottom of interior pot 9 pressure (while elastic displacement safety
Device 18 and limit warm safety device 4 also can forced compression), compression bar 1508 compresses Flexible Reset component 1509 and simultaneously moves down, from
And the spool 1505 connecting with compression bar 1508 is driven to move down, the sealing ring 1504 of the root of the locating flange of spool 1505 will
The counterbore of first connected space bottom seals, to close the connection of the first connected space or more, thus by the first gas outlet 1511
Separate with the first air inlet/outlet 1503.Since the movement of spool 1505 can't change the first air inlet/outlet 1503 and the second disengaging
The connection of port 1512 burns away so ignition tube 12 will not die, since ignition tube 12 is relatively small flame, no
Centre heating heat conducting disk 11 can be heated, within air pressure in pot 9 can decline, after dropping to setting value, pressure maintaining assembly
Compression bar 1508 in safety device 15 is jacked up under the action of Flexible Reset component 1509, and band movable valve plug 1505 moves upwards,
So that the first air inlet/outlet 1503 is connected to the first gas outlet 1511, infrared stove head 5 continues to heat, and the air pressure in interior pot 9 is again
Secondary rising.Above-mentioned pass gas is repeated, is depressured, opens gas, igniting, boosting, such cycle operation plays pressure maintaining effect, until timer
20 times arrived, and disconnected solenoid valve 22 and acted on, and closed gas circuit gas supply, and pressure cooker just stops working completely.
Specifically, the air pressure that pressure maintaining assembly safety device 15 can control in interior pot 9 is floated in 1kPa between 5kPa,
1KPa opening gas circuit, 5KPa close gas circuit, and circulation plays pressure maintaining in a certain range back and forth.
If kettle temperature reaches 150 DEG C or dry combustion method, the bimetal leaf in warm safety device 4 is limited because of high temperature, and leads to it
The contact contact of control disconnects, and connection solenoid valve 22 powers off, and cutting gas valve body is logical to play protected by temperature limitation.
