[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

[0016]As shown in Fig. 1 to Fig. 3, the utility model provides a kind of electric cooker with enamel inner container, includes pot body 1 and the inner bag 2 of being located in this pot body 1, and described pot body 1 mainly is comprised of the cover 11 that is bonded with each other successively, body 12 and base 13; Wherein, described body 12 inside bottom and be positioned at inner bag 2 belows and be provided be used to the temperature control assembly 14 that hangs down temperature control, and the heat-generating disc 15 that is connected with these temperature control assembly 14 conductings, described temperature control assembly 14 includes low temperature outage control module 141 and temperature sensing unit 142, described low temperature outage control module 141 is connected with heat-generating disc 15 conductings, described temperature sensing unit 142 contacts with heat-generating disc 15, and the temperature of heat-generating disc 15 is carried out Real-Time Monitoring; Described inner bag 2 is enamel inner containers, includes metal inner tube 21 and enamel layer 22, and described metal inner tube 21 is made by carbon steel, alloy, cold-reduced sheet, aluminium sheet or stainless steel material, and described enamel layer covers 22 at metal inner tube 21 surfaces externally and internallies; Described heat-generating disc 15 is made by carbon steel plate or cast iron materials, and described enamel layer 22 covers on metal inner tube 21 inside side walls and the inside bottom surface, and by burning till mutual strong bonded one, when assembling is used, this enamel inner container 2 is installed in the body 12, and the enamel layer 22 that covers inner bag 2 bottom outside surfaces is connected with heat-generating disc 15 contacts.

[0017]During electric cooker work described in the utility model, because the thermal conductivity factor of enamel layer 22 is less than the thermal conductivity factor of metal inner tube 21, be that heat transfer speed is slower than metal inner tube 21, metal inner tube 21 has absorbed amount of heat, when metal inner tube 21 carries out the second heat transmission, outwards transmission then is subject to the enamel layer 22 of outer surface covering and the obstruction of outer air, heat transmission is hindered large, inwardly transmission then can be direct with the water in the heat transferred inner bag 2 and rice through the enamel layer 22 of inner surface, heat transmission is hindered little, according to hot transfer law, heats that metal inner tube 21 absorbs its overwhelming majority all Transmit evenly to the enamel layer 22 of inner surface, avoid the loss of heat, and finish from the bottom with all around to the water in the inner bag 2 and Mi Jinhang heating, the inner surface enamel layer 22 of enamel inner container 2 upper ends also can be passed to heat the air in inner bag 2 upper ends simultaneously, heat from the top to water and Mi Jinhang after making it become hot-air, can realize pot meal that 360 ° of comprehensive heat are transmitted, simple in structure, it is fast to conduct heat, pot meal efficient is fast, it is more even to be heated, the meal of stewing out is better, and the enamel layer that is provided with, and hardness is high, corrosion-resistant, wear-resisting, nontoxic, health, safety, the life-span is long, and the meal of stewing out is sticking pot end and sidewall all around also, can not cause waste, it is also easier to clean.

As shown in Figure 4, a kind of based on the control method with electric cooker of enamel inner container described in the utility model, after rice is boiled in pot, carry out low temperature temperature control control by described temperature control assembly 14, stop to utilize the after-heat of heat-generating disc 15 that enamel inner container 2 is heated to heat-generating disc 15 power supplies, utilize simultaneously the enamel layer 22 on the enamel inner container 2 that has stored heat, realize continuing pot meal, until rice cooker is good.Specifically include following steps:

Steps A. external power source is powered, is heated through 14 pairs of heat-generating discs 15 of described temperature control assembly;

The described temperature sensing of step B. unit 142 Real-Time Monitoring heat-generating discs, 15 temperature judge whether rice boils in pot;

The described temperature control assembly 14 of step C. enters low temperature temperature control control model, finishes pot meal; Be that 141 pairs of heat-generating discs 15 of described low temperature outage control module are stopped power supply, heat-generating disc 15 utilizes self waste heat to continue enamel inner container 2 is heated, utilize simultaneously the enamel layer 22 on the enamel inner container 2 that has stored heat, proceed the meal of stewing, when heat-generating disc 15 reaches the lower limit temperature of low temperature pot meal, continue energising, make heat-generating disc 15 be heated to the ceiling temperature of low temperature pot meal, and then outage, so circulate repeatedly, until rice cooker is good.

[0019]Like this, carry out low temperature temperature control control in pot meal process by the temperature control assembly 14 that is provided with in it, more energy-conservation, more environmental protection also can effectively avoid occurring the burnt phenomenon of pot.

[0020]Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
