Abstract
The utility model discloses an electric pressure cooker which comprises a cooker body, an outer cooker, an inner cooker, a cooker cover and a heating disc. A sealing ring is arranged between the cooker cover and the inner cooker; the inner cooker is positioned on the heating disc; and an elastic body is arranged between the heating disc and the bottom part of the outer pot. The electric pressure cooker is characterized in that temperature and pressure control integrated devices are arranged at the bottom of the heating disc and the outer cooker. The electric pressure cooker can be automatically controlled in pressure and temperature through a switch and has the advantages of simple structure, safety and reliability, and low cost.
Description
Technical field
The utility model relates to the pressure cooker technical field, and especially a kind of electric pressure cooking saucepan belongs to the improvement technology that has electric pressure cooking saucepan now.
Background technology
Existing auto-electronic pressure cooker mostly is to control temperature by temperature regulating device independently, by another pressure control device controlled pressure independently.Owing to be to realize temperature-control pressure-control with two independent device, structure is complicated, cost is high.Chinese patent ZL200420046308.1 discloses a kind of auto-electronic pressure cooker temperature-control pressure-control device, better addresses the above problem, but adjusts difficulty, influences production efficiency.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, cost is low, easy to adjust not only electric pressure cooking saucepan of temperature control but also pressure control is provided.
The purpose of this utility model is realized by following technical proposals:
A kind of electric pressure cooking saucepan, comprise a pot body, outer pot, interior pot, pot cover, heat-generating disc, be provided with sealing ring between pot cover and the interior pot, interior pot places on the heat-generating disc, be provided with elastomer between heat-generating disc and the outer pot bottom, it is characterized in that: heat-generating disc bottom and outside pot bottom be provided with the temperature-control pressure-control combined unit.
Further, the temperature-control pressure-control combined unit comprises bimetallic thermostat and pressure-driven mechanism, described bimetallic thermostat comprises flash switch and bimetal leaf, one end of bimetal leaf closely is fixed on the footing of heat-generating disc with flash switch through outer pot, elastomer, and the other end of bimetal leaf joins by the reed of push rod and flash switch; Outside pressure-driven mechanism is fixed on
Portion is not easy to be out of shape the local and corresponding with the position of bimetal leaf of displacement.
Further, also comprise conducting strip, an end of conducting strip is fixed on outer pot bottom, and the other end and bimetal leaf are fixed together.
Further, pressure-driven mechanism comprises support and pressure adjustment screw, and support is provided with and the corresponding screw of pressure adjustment screw, and the pressure adjustment screw is provided with lock nut, and the tip of pressure adjustment screw is over against bimetal leaf.Further, the tip of pressure adjustment screw is near push rod.
Temperature-control pressure-control principle of the present utility model is as follows: when pressure cooker is in the pressure duty, pot inner pressure reaches elastomer through interior pot, heat-generating disc, make elastomer and outer pot produce strain, heat-generating disc is to bottom offset, and drive bimetallic thermostat is to bottom offset.When setting value, the adjustment screw of driving mechanism is touched flash switch, cuts off the electricity supply.Because pressure cooker is when the pressure duty, the temperature of bimetallic thermostat induction is lower than its operating temperature, and this moment, bimetallic thermostat practical function was equal to microswitch.When the anhydrous work of pressure cooker or operating pressure are very low (as the very strong material of culinary art suction time), the bimetallic thermostat to bottom offset apart from deficiency so that the flash switch action, this moment, the bimetallic thermostat played the temperature control effect.When temperature reaches when setting value, the flash switch action power dump, that is to say this temperature-control pressure-control combined unit as long as pressure or temperature one of them just can move when reaching setting value, thereby control the duty of heat-generating disc.
The beneficial effects of the utility model are: just can realize the temperature and pressure of pressure cooker is controlled automatically with a flash switch, and simple in structure, safe and reliable, cost is low, and improved pressure-driven mechanism makes the adjusting of operating pressure more convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified.
As shown in Figure 1, the utility model comprises pot body 1, outer pot 2, interior pot 3, pot cover 7, heat-generating disc 4.Be provided with sealing ring 8 between pot cover 7 and the interior pot 3, interior pot 3 places on the heat-generating disc 4, is provided with elastomer 5 between heat-generating disc 4 and outer pot 2 bottoms.The bimetallic thermostat comprises flash switch 61, adjustment screw 611, bimetal leaf 612, push rod 614.Mixed up the flash switch 61 of operating temperature by adjustment screw 611, be fastened on heat-generating disc 4 footing through conducting strip 62, outer pot 2, elastomer 5, an end 613 of conducting strip 62 1 ends and bimetal leaf 612 joins, and the other end is fixed on outer pot 2 bottoms.Pressure-driven mechanism comprises support 631, pressure adjustment screw 632 and lock nut 633, is arranged at the place that the outer pot bottom is not easy to produce distortion, displacement.Its position just makes its adjustment screw 632 tips near the push rod 614 of bimetallic thermostat.Pressure adjustment screw 632 transfers to desired location, and by lock nut 633 lockings.
In electric pressure cooking saucepan when work, increase with pot inner pressure, and pot inner pressure reaches elastomer 5 through interior pot 3, heat-generating disc 4, makes elastomer 5 and outer pot 2 produce strains, and heat-generating disc 4 is to bottom offset, the bimetallic thermostat along with heat-generating disc 4 to bottom offset.When displacement reached setting value, the pressure adjustment screw 632 of pressure-driven mechanism was touched flash switch 61, disconnects heater circuit.Because this moment, outer pot 2 cooking bottom temperatures were lower than the operating temperature of bimetallic thermostat.At this moment, the effect of bimetallic thermostat is equal to microswitch.When pressure cooker dry combustion method or the very strong material of culinary art water imbibition, when not having pressure or pressure very low in the pot, the bimetallic thermostat do not arrive setting value to bottom offset, this moment, outer pot 2 cooking bottom temperatures constantly rose, temperature is passed to bimetal leaf 12 through conducting strip 62, when temperature reached the operating temperature of bimetallic thermostat, flash switch 61 actions disconnected heater circuit.This moment, the bimetallic thermostat worked as temperature controller.
