Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in the structural representation of pressure-controlled type electric pressure pot of the present utility model in Fig. 1, comprise pot cover 1, sealing ring 2, interior pot 3, outer pot 4, heating plate 5, the pressure-detecting device being arranged on the some elastomeric elements between heating plate 5 and outer pot 4 and being arranged on below outer pot 4, heating plate 5, pressure-detecting device is connected with control circuit board, the elasticity realized between outer pot 4 and interior pot 3 by elastomeric element is connected, the line pressure shift of interior pot 3 is converted to the line pressure shift of outer pot 4, and by pressure-detecting device to control circuit board transmission of signal, control the action that heating plate 5 starts heating or closes heating.
Described pot cover 1 is fastened on outer pot 4, pot cover 1, sealing ring 2, interior pot 3, outer pot 4 is in turn connected to form a seal, shown in figure, sealing ring 2 is provided with upper and lower lip, upper lip and pot cover 1 seam portion seal and are adjacent to, lower lips and interior pot 3 seam portion seal and are adjacent to, thus guarantee to form seal chamber between pot cover 1 and interior pot 3, because the sealing effectiveness of upper and lower lip is linear contact lay, sealing property is reliable, when interior pot 3 pressure exceedes setting value, interior pot 3 is excessively to bottom offset, lower lips seal failure is made to produce gap, realize pressure release effect, possesses good security performance.The amount of elastic deformation of elastomeric element is the safety travel providing necessity to bottom offset of interior pot 3.As as shown in Fig. 2 to Fig. 5, described elastomeric element is the disk spring 6 of band open slot, towards inner side, horizontal flange forms upper bracing ring 61 to the miner diameter end of disk spring 6, the bigger diameter end of disk spring 6 forms lower support circle 62, cone wall portion between upper bracing ring 61 and lower support circle 62 forms elastic deformation area, radial through upper bracing ring 61 also extends to cone portion to offer the outline line projected in the horizontal plane is criss-cross open slot 63, notch to the bottom land of open slot 63 is up-small and down-bigly extend out formula structure gradually, adopt the disk spring 6 of special construction design can provide more elastic deformation amount than the tabular elastomeric element generally applied, this provides longer safety travel by for moving down of interior pot 3, safety relief is ensured when hypertonia.And, longer displacement stroke can be provided for the sense contact of pressure-detecting device, be conducive to pressure-detecting device senses change in pressure, thus improve pressure controling precision.Owing to bearing the pressure of alternate load at high temperature under high pressure, the notch of open slot to bottom land is arranged to up-small and down-bigly extend out formula structure gradually, the stress equilibrium of bracing ring 61 bearing load under pressure state can be made and spread downwards gradually via cone wall portion, increasing substantially fatigue resistance and creep-resistant property under HTHP.Upper bracing ring 61 with bore between lower support circle 62 that wall portion is connected by arc transition first bore wall 64 and second and bore wall 65 and form, outside first cone wall 64, the curvature of profile is greater than the curvature of profile outside the second cone wall 65, can make to bore wall portion like this to bear the stress that bracing ring 61 conducts in a compressed state in elastically-deformable process, obtain fast uniform diffusion, improve the creep-resistant property under the condition of high temperature.As a specific embodiment, the radius of curvature ratio of profile outside profile outside the first cone wall 64 and the second cone wall 65 is set to 8.5:10.In order to improve the fatigue resistance under high-temperature high-pressure state, the curvature of profile outside first cone wall 64 can be set to the curvature being greater than profile inside the first cone wall 64, while the diffusion of outside profile compression chord, inner side profile tension stress impact, therefore such curvature setting effectively raises the fatigue resistance of the first cone wall.As a specific embodiment, the radius of curvature ratio that profile and first outside the first cone wall 64 bores profile inside wall 64 is set to 4.3:5.
Disk spring 6 is uniform is as shown in fig. 1 three, the quantity that certainly can set according to practical structures and pressure cooker watt level adjustment disk spring 6 and position adjustment, in embodiment of the present utility model, three disk springs 6 are positioned in same level, the pressure that interior pot 3 is transmitted is kept in balance, and making outer pot 4 bottom even stressed, elastic deformation is uniform and stable.Lower support circle 62 is supported on bottom outer pot 4, and upper bracing ring 61 is resisted against on the leg 51 of heating plate 5, and leg 51 and disk spring 6 are located by connecting integral by hold-down screw 7 and outer pot 4.Make owing to usually adopting thinner material bottom outer pot 4, intensity is little, by extension supporting backing plate 11 between lower support circle 62 and outer pot 4, so both can increase the structural strength bottom outer pot 4, reduce the difference of outer pot bottom 4 deformation quantity everywhere, strong support can be formed to lower support circle 62 again, guarantee under pressure state bottom outer pot 4 that stress equalization is stable and the elastically-deformable linearity keeps good, thus improve pressure controling precision.
Pressure-detecting device can adopt pressure sensor collocation gauge tap, adopts the senser element of the various popularization and application such as inductance sensor, displacement transducer according to practical structures.Select in the present embodiment to adopt conventional microswitch 8, default line pressure shift distance is kept by between the sense contact 9 of microswitch 8 and outer pot 4 exterior bottom, owing to adding elastic deformation amount, be conducive to sense contact 9 senses change in pressure like this, improve pressure controling precision.Also the flat bolster 10 matched with sense contact 9 can be set up in outer pot 4 exterior bottom, structural strength is increased by setting up flat bolster 10, the elastic deformation bottom outer pot 4 can be made to provide the linearity better pressure signal transmission by rigid pressure transmission, be convenient to Stress control.And, on the basis of structural strength keeping outer pot 4 body necessity, also appropriateness can reduce outer pot 4 bottom thickness, bottom guarantee outer pot 4 while favorable elasticity deformation performance, significantly save material cost, promote economic benefit.
The cooking methods of the pressure-controlled type electric pressure pot in the present embodiment, comprises the steps:
1) open electric pressure cooking saucepan switch, microswitch 8 closes, and heating plate 5 heats;
2) when heating plate 5 heats, certain pressure is produced in interior pot 3, because outer pot 4 and pot cover 1 close fastening by sealing ring 2, seal chamber is formed between pot cover 1 and interior pot 3, pressure makes interior pot 3 to bottom offset, produces by disk spring 6 safety travel that elastic deformation gives the displacement of interior pot 3;
3) pressure of interior pot 3 passes to bottom outer pot 4 and produces elastic deformation by the elastic deformation of disk spring 6, sense contact 9 is touched when deformational displacement amount bottom outer pot 4 arrives range of set value, then microswitch 8 disconnects, heating plate stops heating, in interior pot 3, pressure slowly declines, disk spring 6 recovers original state, and microswitch 8 closes again;
4) heating plate 5 re-starts heating, and periodic duty is cooked successively.
The utility model is not limited to above-described preferred embodiment; the known technology can known based on those skilled in the art or to adopt in prior art institute can the various distortion of equivalence replacement and the embodiment of change; every based on spirit of the present utility model or technical conceive, all should be included within protection domain of the present utility model.
