The timer of this electrical heating pressure cooker (24) is selected the FDJ60 type, and overheat protector is selected the RJ-2 type, and RTC-3, RTC-6, RTC-9 type are selected in electrothermal tube (20), (29), (30), and tape light K switch 4, K5, K6 select FCD ₁Type.

When using this electrical heating pressure cooker, put into processed food in the pot thorax (8), tighten pot cover (5) with handle (6), socket (25) is inserted the 220V AC power, plate electro kinetic potential pipe switch (26) successively, (39), (40), can obtain the electrical heating power supply (300W of 6 kinds of power, 600W, 900W, 1200W, 1500W, 1800W), when going out vapour post (3) outlet when emerging steam, go out vapour post (3) and put pressure-bearing cap (1), and timer K2 adjusted the required time of processed food, behind setting time, the electrical heating power supply is cut off in timer K2 automatic disconnection.

In timer K2 setting time; pressure in pot thorax (8) reaches and gives the pot gun pressure power limiting value of adjusting earlier; vapour pressure in the pot thorax (8) is just with pressure-bearing cap (1) jack-up; the vent port (2) of pressure-bearing cap this moment (1) and the outlet that goes out vapour post (3) on the pot cover (5) communicate; steam is discharged from vent port (2); thereby keep keeping constant pressure in the pot thorax (8); just in case pressure-bearing cap (1) is malfunctioning; pot thorax (8) internal pressure surpasses setting valve; meltable neonychium this moment (4) and (7) is successively opened steam bleeding, guarantees that pot thorax (8) internal pressure can not continue to rise.

When temperature in the pot thorax (8) surpasses setting valve; be installed in overtemperature protection moving plate (35) on the calandria base plate (31) because of adding thermal expansion; and it is outwardly-bent; thereby contact (33) and the contact (34) on the overtemperature protection moving plate (35) on the overtemperature protection egative film (32) are separated; be that K3 disconnects; cut off the power supply of 300W electrothermal tube (28) and 900W electrothermal tube (30); 600W electrothermal tube (29) energising is only arranged this moment; the interior temperature of pot thorax (8) descends; when temperature is lower than definite value in the pot thorax (8); overtemperature protection moving plate (35) resiles because of heat reduces, thereby has connected egative film contact (33) and moving plate contact (34), i.e. K ₃Connect, 300W electrothermal tube (28) and 900W electrothermal tube (30) are connected power supply, and the interior temperature of pot thorax (8) rises again.Set screw (36) on the overtemperature protection moving plate (35), the diastrophic temperature value of protection moving plate (35) that is used for adjusting, when screwing set screw (36) inwards, the temperature height of adjusting of overheat protector action, on the contrary the temperature of adjusting of overheat protector is low.The pot wall (7) of this electrical heating pressure cooker body and the seated (12) of calandria (13) are by being threaded, and the turn screw thread can make a pot wall (7) separate with seated (12), is convenient to the cleaning pot body.
