Electromagnetic induction heating electric rice cooker
The utility model relates to a kind of cook utensil, specifically a kind of electric cooker.
Traditional electric cooker is equiped with heat-generating disc on base, the pot bottom outside was heated food in the pot by the heat conduction and is boiled in heat-generating disc was close to, and the control of steam pressure in its pot is adopted steam vent is set on pot cover, when in the pot during steam pressure overrate, adopt the exhaust mode decompression.This mode by the conduction heating, its thermal efficiency is not really high; In addition, the food that the concentration that boils is big stops up steam vent unavoidably, and at this moment if do not reduce firepower, pot inner pressure rises, and easily produces and explodes, also power consumption simultaneously.
The purpose of this utility model is to change traditional mode of heating, makes the direct heat food of pot body, to improve the thermal efficiency.
For achieving the above object, the utility model adopts following technical scheme:
Change the mode of heating of traditional electric cooker into electromagnetic induction heating by conduction, this electric cooker comprises pot cover, center, shell, stay-warm case, interior pot, wiring board, display board, control lever, base, temperature limiter, temperature controller, power pack, sealing ring and lid are buckled, interior pot places in the stay-warm case, pot cover is hinged by pivot pin and center, and it is fastened on center and the shell with lid button, buckling surface is provided with sealing ring, the outside, pot bottom center in temperature limiter is close to, control by control lever, wiring board and display board are installed on the shell, power pack, stay-warm case and shell all are installed on the base, center is installed in the shell upper end, temperature controller is installed in the stay-warm case bottom outside, and it also comprises electromagnetic coil, in the interlayer between interior pot bottom and stay-warm case.
The pot bottom outside in described electromagnetic coil is pressed close to, from temperature limiter end face cylindrical joint place to the even coiling of side lower edge.
Described electromagnetic induction heating electric rice cooker also comprises air bleeding valve and the safety valve that is installed on the pot cover.
The utility model and traditional electric cooker have relatively manifested following superiority: 1, owing at interior pot bottom heat-generating disc is set and changes into by the conduction heating and at interior pot bottom electromagnetic coil is set and carries out eddy-current heating traditional, inner pot body is a carrier, it is again heater, thereby reduced thermal loss, improved the thermal efficiency; 2, owing on pot cover, set up air bleeding valve and safety valve, realized adjustable in pressure, used safer; 3, owing to the employing electromagnetic induction heating, homogeneous heating, the energy-and time-economizing, meal flavor is not half-cooked.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the longitudinal section of the utility model electromagnetic induction heating electric rice cooker.
Accompanying drawing has been described an embodiment of the present utility model.As shown in the figure, present embodiment comprises pot cover 1, center 2, shell 3, stay-warm case 4, interior pot 5, wiring board and display plate component 6, control lever 7, base 8, temperature limiter 9, temperature controller 10, electromagnetic coil 11, sealing ring 12, air bleeding valve 13 and safety valve 14, interior pot 5 places in the stay-warm case 4, pot cover 1 is hinged by pivot pin and center 2, and it is fastened on center 2 and the shell 3, buckling surface seals with sealing ring 12, the pot 5 bottom centre outside in temperature limiter 9 is close to, by control lever 7 controls, wiring board and display plate component 6 are installed on the shell 3, stay-warm case 4 and shell 3 all are installed on the base 8, center 2 is installed in the upper end of shell 3, temperature controller 10 is installed in stay-warm case 4 bottom outside, in the interlayer of electromagnetic coil 11 between interior pot 5 bottoms and stay-warm case 4, the bottom outside of pot 5 in pressing close to, the bottom of a pan of pot 5 and temperature limiter end face cylindrical joint place are between the lower edge of side in evenly being wound on, and air bleeding valve 13 and safety valve 14 are installed on the pot cover 1.After connecting power supply, pot 5 eddy-current heating in the electromagnetic coil 11 of pot 5 bottom outside makes in being wound on change traditional electric cooker and at interior pot bottom a heating board are installed, and utilize the mode of heating of pot in the heating board heating.Air bleeding valve 13 is used for a steam pressure in the control pot, and when steam pressure reached specified limit value, the rush to summit spool of air bleeding valve 13 of steam was with spring compression, exhaust step-down.This air bleeding valve 13 can be realized adjustable in pressure, and the method for regulating the specified limit value of pressure often has two kinds: a kind of is the diameter that changes spring; Another kind is the length of regulating spring in valve body.When steam pressure continue to increase, surpass specified limit value, air bleeding valve 13 still is not enough to the exhaust step-down or when breaking down, the fuse piece of safety valve 14 is washed open by steam, pressure release rapidly.
