Specific embodiments

As depicted in figs. 1 and 2, the utility model has interior pot (3) and outer pot (5), interior pot is the container of dress food, there are six projections the outer pot upper edge, the outer pot bottom surface connects heat-generating disc (11), be placed with interior pot (3) above the heat-generating disc (11), porose and elasticity connection sensor (7) in the middle of the heat-generating disc (11), electric controller (8) is equipped with in a suitable place in the pot, and electric controller is connected with sensor electrical, when heating is cooked, pot (3) in sealing ring (2) sealing, pressure rises, because pot cover (11) fastens outer pot, pressure rises the interior pot in back (3) to moving down, the bottom of a pan compresses heat-generating disc (6) in making, and interior like this pot pyroconductivity improves, and back pressure is born by the heat-generating disc and the outer the bottom of a pan because the interior the bottom of a pan is stressed, therefore the bottom of a pan need not to do too thickly in, has increased the bottom of a pan heat conduction like this.Littler in the long-term this bottom of a pan, back of using simultaneously than the degree of deformation of domestic and international full electric control electric pressure cooker.Structure therefore of the present utility model is than the structure of full electric control electric pressure cooker is more scientific and reasonable both at home and abroad at present, and comparable full electric control electric pressure cooker is energy-conservation many both at home and abroad at present.Shell (5) is for attractive in appearance, insulation and electric controller parts etc. is installed.

Narrate the complete automatically controlled process of the utility model below.Electric controller (8) can be made separately two, also can be to make one, if control with the chip integrated circuit, generally is to make two; If sensor is a bimetal strip thermostat, then electric controller also can be made one, with sensor is that thermistor is an example, when being heated to 100 ℃ of left and right sides when plugging in, thermistor is experienced the relay normally open contact closure of chip integrated circuit electric controller after this temperature, making the 4th control point (15) become closure state by normally open finishes up to cooking, timing system (14) timing of starting working, after the time of setting, time switch (13) also is that relay contact becomes normally open by normally off, the end of cooking.Here, can set the different timings of cooking according to different food, these timings can be made the various menu key, and a button is promptly represented the time of this menu.

As long as said process is represented to reach about 100 ℃, just can finish said procedure, and in fact the present invention cooks at 115 ℃～120 ℃ left and right sides constant temperature mainly, at this moment this function has been carried out at electric controller second control point.When sensor was experienced 120 ℃ of left and right sides temperature, electric controller made the contact at second control point become normally open by normally off, and kept constant temperature in this temperature range, can make with the fuzzy logic mode of heating to remain in the pot about 120 ℃.After the time that has arrived the timing system setting, the time switch contact also is that relay contact disconnects, and heating stops.Change low temperature insulation program then over to, carried out at the 3rd control point by electric controller and sensor, when the 3rd control point was lower than 70 ℃ of left and right sides temperature, relay contact became normally off by normally open; The closing of contact starts heater circuit when being lower than 70 ℃ of left and right sides temperature.
