[specific embodiment]

New ideas of the present invention are not sticking does not stick with paste gruel-cooking cooker, and as shown in Figure 2: comprise pot body portion 30, power unit 40 and temperature show and control section 50.

Wherein, pot body portion 30 comprises a pot body upper surface insulation and thermal insulation layer 31, the inboard insulating heat-conductive layer 32 of pot body; Pot nside eddy current heating interlayer 33 (this interlayer divides two parts, and 75% right and left upper is identical with insulating heat-conductive layer 32 material, and about 25% bottom is an eddy current heating work layer); Be enclosed with the heat-resisting interlayer 34 of insulation of solenoid; Solenoid 35, the external side insulation and thermal insulation layer 36 of pot, bottom of pot body insulation and thermal insulation layer 37 and insulation handle 38;

Power unit 40 comprises power connection 41, power switch 42, cook indicator lamp 43 and insulation indicator lamp 44;

Temperature, time showing and control section 50 comprise temperature sensor 51, temperature, time display screen 52 and temperature, time storage control 53.

The specific embodiment is an energized joint 41, turn on the power switch 42 after, the indicator lamp 43 of cooking lights; Solenoid 35 will can be known that alternating current will produce the identical alternating magnetic field of frequency through alternating current by the law of electromagnetic induction; Alternating magnetic field is during through the very high eddy current interlayer 33 of magnetic conductivity; Meeting produces strong eddy current and generates heat, and heat radiation is passed to the inboard insulating heat-conductive layer of pot body, takes food in the heating kettle.For using water wisely and avoid dry combustion method, the eddy current zone of heating only is arranged on bottom of pot body approximately to 1/4 pot of eminence, and above thus is the insulating heat-conductive layer.During boiling, only need that liquid level is covered 1/4 place more than the bottom of a pan (being provided with the caution waterline at this) and get final product.

The pot wall mode of heating that is adopted, different fully with the bottom of a pan mode of heating of existing gruel-cooking cooker.In the digestion process, food can because be deposited to the bottom of a pan, contact with the high temperature the bottom of a pan as using existing gruel-cooking cooker in the pot, and can't convection current because of the gravity effect, cause food to receive heat continuously and burn, sticking pot.Sidewall mode of heating among the present invention, even contact with food, also the deadweight because of food descends, and stirs and convection current with inhomogeneous generation of heat, so food can not pasted on the pot wall; And heating process is not participated in the bottom of a pan, is not burned even can not burn bottom therefore food is deposited to yet.The temperature sensor 51 that is installed on the bottom of a pan can show the temperature of the bottom of a pan food constantly; Because heat rises the cold physical action that falls; Cooking bottom temperature is the minimum temperature of food, if cooking bottom temperature reach food steaming, boil temperature, just can guarantee that all foods all are in steaming, boil temperature.To different food because required steaming, the temperature of boiling, time are different; Can come to be provided with voluntarily through temperature, time storage control 53; Also can select in temperature, the time storage control 53 default settings of the required temperature and time of the food multiple commonly used of storage; Easy to operate, simple and practical.

Food arrives temperature or the time set after steaming, boiling, and is the same with existing a lot of automation gruel-cooking cookers, will get into keeping warm mode automatically, and insulation indicator lamp 44 lights.

In order to improve safe handling property of the present invention; The pot body adopts: upper surface insulation and thermal insulation layer 31, pot body inboard and eddy current working lining top insulating heat-conductive layer 32, the heat-resisting interlayer 34 of insulation of parcel solenoid; The external side insulation and thermal insulation layer 36 of pot; Bottom of pot body insulation and thermal insulation layer 37, insulation handle 38, and overload is installed at the power connection place, short circuit is insured.These selections and setting had both made the heating heat be difficult for scattering and disappearing, and improved the efficiency of heating surface, and energy-conserving and environment-protective have improved the safety in utilization of pot again.
