Embodiment 1

[0025] Embodiment 1: Referring to Fig. 1, a cast iron electric rice cooker for continuous cooking after power failure includes an outer shell, an insulating layer, a cast iron heating plate, a cast iron liner, and an intelligent control system for function keys, wherein the outer shell 5 is provided with an insulating Layer 4 and shell 5 are made of plastic or plastic steel structure. The insulation layer 4 is wrapped with insulation cotton 6 and metal foil film 8 to achieve heat insulation and constant temperature. The cast iron heating plate 1 is cast by melting and casting pig iron metal materials. The cast iron heating plate 1 contains a resistance wire heating tube 7, and the bottom of the cast iron heating plate 1 is wrapped with thermal insulation cotton 6 and a metal foil film 8. The cast iron inner tank 2 is smelted and cast with pig iron. Car processing, two times of spraying ceramic glaze and two times of sintering, each function key control circuit of the function k...

Embodiment 2

[0029] Embodiment 2: refer to figure 2 As shown, the production process steps of the cast iron heating plate 1 are as follows:

[0030] ①Pig iron smelting: use pig iron metal material to smelt at high temperature into molten iron for casting. The temperature of molten iron is about 1600°C, and the harmful elements will be burned at high temperature during smelting;

[0031] ② Pouring blank: when the temperature of the molten iron is lowered to 1400°C, it is poured twice, including the resistance wire heating tube (7) in the cast iron heating plate, which is beneficial to the heat absorption and heat collection function of the cast iron plate;

[0032] ③Tempering and tempering: the cast iron heating plate blank is subjected to high temperature 800°C physical performance tempering to prevent deformation;

[0033] ④Finish turning processing: For the cast iron heating plate blank, after finishing turning, the thickness of the cast iron heating plate is 13-15mm, which is benefici...

Embodiment 3

[0035] Embodiment 3: refer to figure 2 As shown, the production process steps of the cast iron liner 2 are as follows:

[0036] ①Pig iron smelting: use pig iron metal material to smelt at high temperature into molten iron for casting. The temperature of molten iron is about 1600°C, and the harmful elements will be burned at high temperature during smelting;

[0037] ② Pouring blank: When the molten iron cools down to 1450°C, it is poured into shape at one time;

[0038] ③Tempering and tempering: 800°C high-temperature physical performance quenching and tempering of cast iron liner blanks to prevent deformation;

[0039] ④Finish turning processing: the blank of the cast iron liner is processed by finish turning to ensure that the thickness of the side wall of the liner is 2~2.2mm, and the thickness of the bottom wall of the liner is 3.5~3.8mm, which is conducive to a large amount of heat collection and energy storage of the cast iron liner. It is beneficial to the three-dime...

Abstract

The invention discloses an outage continuous cooking cast iron electric rice cooker and a casting process thereof. The outage continuous cooking cast iron electric rice cooker includes an outer shell,an insulation layer, a cast iron heating plate, a cast iron liner, and a function key intelligent control system, the outage continue cooking cast iron electric rice cooker is characterized in that the outer shell is internally provided with the insulation layer, the insulation layer is wrapped with insulation cotton and a metal foil film, thermal insulation and the constant temperature are achieved, the cast iron heating plate is smelted and cast with pig iron metal materials, the cast iron heating plate internally contains a resistance wire heating pipe, the bottom of the cast iron heatingplate is wrapped with the insulation cotton and the metal foil film, the cast iron liner is melted and cast with pig iron to cast an inner hair germ part, and the inner hair germ part is formed by fine car processing, twice ceramic glaze spraying and twice sintering, and each function key control circuit of the function key intelligent control system is matched by a corresponding intelligent control program process technology. The outage continuous cooking cast iron electric rice cooker and the casting process thereof have the advantages of being fast in heating, good in heat preservation, energy saving, maintenance in original taste, delicious in flavor, and good in health.

Description

technical field [0001] The invention belongs to the technical field of smelting and casting of pig iron metal materials, in particular to a cast iron electric rice cooker for continuous cooking after power off and its casting process. Background technique [0002] At present, the rice cookers used are almost all made of aluminum or stainless steel, and there is no real cast iron rice cooker in the market; people agree that rice in an iron pot is delicious, and rice cooked in an iron pot is soft and delicious; therefore, if you create a A cast iron rice cooker that is environmentally friendly, energy-saving, and healthy, will be loved and welcomed by thousands of households. Contents of the invention [0003] The purpose of the present invention is to design and manufacture a cast iron electric rice cooker for continuous cooking when the power is off, which not only saves energy, but also makes the rice cooked in the iron pot soft and delicious, which is definitely popula...
