Specific embodiments
As depicted in figs. 1 and 2, the present invention 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, after rising, pressure make interior pot (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 be done 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 invention 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 the electric controller parts is installed.
Narrate the complete automatically controlled process of the present invention 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 ℃ of 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 often opening situation; The closing of contact starts heater circuit when being lower than 70 ℃ of left and right sides temperature.
Above-mentioned is the program of carrying out under general normal condition.When the heating abnormal conditions occurring, make when pot is low to surpass more than 100 ℃ temperature, electric controller made relay contact become normally open by normally off at first control point after sensor was experienced this temperature, cut off heater circuit.
In sum, Fig. 2 is the circuit design equivalence sketch of the simplest science of regulation and control electric pressure cooking saucepan temperature, because food is actually and just begins to boil about 100 ℃, the present invention just connects timing circuit and starts the clock about 100 ℃, like this no matter water, temperature difference different with size of food can both be boiled with a kind of food by the identical time and made food boil to such an extent that just arrive the duration and degree of heating in the pot.Therefore and,, also can make electric pressure cooking saucepan as the effective work of ordinary electric rice cooker even pot gas leakage does not reach 120 ℃ owing to be at 100 ℃ of beginning make contacts, one cuts off heater circuit automatically to setting-up time.
In order to save material and to improve compressive resistance, the present invention preferably uses the thin-walled outer pot.First kind of thin-walled outer pot is as described in 03178567.0 as the patent No., as shown in Figure 3; the pot of thin-walled pot body (17) below the projection of outer pot upper edge welds reinforcement (16) on the body wall, also can as described in another patent 200420008063.3 being welded on pot wall after the anti-limit stretching of outer pot upper edge projection.Here the inventor reintroduces the form of another kind of thin-walled outer pot, and Here it is makes outer pot with the aluminum alloy materials ironing.
The pot body of existing usual pressure pot has and adopts aluminium ironing, electric pressure cooking saucepan pot body also to have to adopt pot material ironing, these pots body all to be used for adorning food, and is very high to the healthy and safe performance requirement of material.And as the outer pan body of electric pressure cooking saucepan, never the someone proposes the scheme of ironing, and also the someone proposes to make outer pot with aluminum alloy materials.
Pot alloy material ironing outer pot of the present invention as shown in Figure 4, big and aluminium alloy that stretch easily is drawn into that the bottom of a pan (20) is thick, limit wall (19) thin intensity, the thick base substrate of upper wall (18), make six in the upper edge and protrude position (21), the bottom of a pan is gone out various holes and is assembled the connection miscellaneous part outside again.Because outer pot is not a dress food, therefore the corrosion resistance to material reaches less demanding to health effects, aluminum alloy materials is more cheap and more corrosion-resistant than common iron plate than stainless steel, and therefore the outer pot made from it has suitable advantage, and it is applicable to all compression type electric pressure cooking saucepans.
