The specific embodiment

As shown in Figure 1, a kind of multifunctional household electric cooker, form by pot body 1, pot cover 2, steaming ware 7, pot courage, heater, two bladder structures that described pot courage is made up of outer courage 3 and inner bag 4, it is characterized in that: described heater is made up of heat-generating disc 5 and insulation belt 6, heat-generating disc 5 is located at the below of the outer courage 3 in pot body 1, and insulation belt 6 is located at the periphery of the sidewall of outer courage 3; Described inner bag 4 is pot courages in the pottery, and described outer courage 3 is aluminium enamel outer pot courages.On pot cover, be provided with watertight composition 18, between watertight composition 18 and pot cover end face, be provided with magnetic vapour hood 16, thermistor temperature sensor 12, synchronous motor 14, automatic digital display function panel 15.Heat-generating disc top is by the outer courage heat conduction of enamel aluminium, in the handware design with heat-generating disc and enamel aluminium outside courage be fixed together closely, the thermal coefficient of expansion of the metal of reduction has improved heat-transfer effect, test data proves in the experiment: quick heating, be heated evenly.Data show: three-dimensional heater cooking bottom temperature can reach more than 250 ℃ in 2 minutes, can reach in 3 minutes more than 300 ℃, cooked if heat-generating disc directly heats pottery pot courage, can occur because phenomenons such as half-cooked rice, the crust that is burned; Bubble disperses when to boil water, concentrates inadequately.

As shown in Figure 2, heat-generating disc 5 belows are sealed by iron plate, the fast rapid heat dissipation because the iron plate attribute absorbs heat, therefore below iron plate, installed heat-preservation cotton additional, after iron plate and heat-preservation cotton are combined, form complementary, iron plate with heater progressively the unnecessary heat in the temperature-rise period absorb rapidly, heat-preservation cotton, iron plate have formed the energy storage heat-insulation layer, when heating ceramic pot courage 3L water is to boiling water under the 900W power condition, under the situation that does not have the energy storage heat-insulation layer, needing the time is 35 minutes, and after having installed " energy storage heat-insulation layer " additional, be 29 minutes in the following time of similarity condition, save time 20%.

As shown in Figure 3, described steaming ware 7 is by internal layer 8 that is close together and the outer 9 double-metal layer structures of forming, internal layer 8 is different with the thermal coefficient of expansion of outer 9 used metal materials, on internal layer 8 and outer 9, all be provided with a plurality of steam holes 10, and the steam hole 10 interlaced distributions on the steam hole on the internal layer 8 10 and outer 9.The metal material of described double-level-metal face adopts aluminium and iron.

As shown in Figure 4,: described pot cover 2 is provided with magnetic vapour hood 16, described magnetic vapour hood 16 is made of heat conduction aluminium shell 19 and magnetic metal sheet I 20, magnetic metal sheet II 21, be respectively equipped with the small de-air hole 22 of interlaced distribution on magnetic metal sheet I 20, the magnetic metal sheet II 21, heat conduction aluminium shell 19 surfaces become the Bird's Nest shape.

Described pot cover 2 is provided with synchronous motor 14, in the pot courage and be positioned at synchronous motor 14 under be provided with and bake and bank up with earth suspension member, synchronous motor 14 drives bakes and banks up with earth the suspension member rotation.

In the control circuit as shown in Figure 5, thermistor temperature sensor 12, synchronous motor 14 and automatically digital display function panel 15 connect with heat-generating disc 5, hand timer 17 and insulation belt 6 and the pressurized temperature controller 13 that automatically resets is connected.

Described pressurized automatic reset switch 13 is the highest withstand voltage and high-temperature resistant parameters of the product that provides of pottery pot courage producer relatively, shift motion when conversing the relative pressurized under the relative temperature, pressurized automatic reset switch 13 promotes superhigh temperature and can regulate the temperature controller that automatically resets when surpassing the temperature that needs or pressure.

Three-dimensional heating mode, guaranteed that ceramic pot courage is heated evenly, can regulate operating temperature 300 ℃-480 ℃ (optional power is 700W-900W), this multipurpose domestic electric-heating cooking utensil heats 3L water with pottery pot courage, the fastest 23 minutes, the slowest 29 minutes, the traditional electrical pot for cooking rice thermal efficiency is 90%-93% relatively, and during with the dry combustion method of temperature pottery pot courage, the safe working temperature of three-dimensional heating mode is below 480 ℃.In the pot courage, be equipped with toaster, barbecue rack, roast chicken hanger bracket, fried basket, puffed rice to stir annexes such as hanger bracket.During as the need roast food, inner bag is taken out, toaster, barbecue rack, roast chicken hanger bracket are placed in the outer courage and get final product.In boiling, fried, stewed or when baking, produce heat energy simultaneously by the metal heat preservation band on heat-generating disc and the aluminium enamel pot courage, reach three-dimensional and generate heat, and food is heated fast.When boiling, fried, stewed or baking reach certain hour, cut off the heat-generating disc power supply automatically or send out and hold band, at this moment heat-insulation layer continues to carry waste heat energy.

When steaming a small piece of land surrounded by water, be heated and the exhaust that the pot body space is interior is the progressively outer discharging of branch course pot, the internal layer and the skin that steam on the ware are close together, form air-locked steaming ware of sealing, when the steaming ware of double-metal layer is heated to 77 ℃, because thermal coefficient of expansion difference, double-metal layer separates, in making, steam hole conducting on the skin, steam advances to steam in the steam room on ware top by steam hole 10 dischargings, when steam room is heated to 95 ℃, bimetallic vapour hood on the pot cover is opened exhaust, and circuit disconnects simultaneously, transfers heat insulation function to, the interior mean temperature of pottery pot courage is 85 ℃ during heat insulation function, and fluctuation range is at 74 ℃--90 ℃.
