Abstract
The utility model discloses an electrothermal pot, in particular to an electrothermal tile pot whose heating container is made of heat-resistant insulating materials such as the ceramics or metallic materials coated with a heat-resistant insulating material layer such as the porcelain enamel. The heating body of the utility model adopts a metal conductor fixed on the outer surface of the heating container as an extraction electrode, the electrothermal film liquid is coated, after the air dry, an electric heating membrane is formed, and an insulating protective layer is arranged at the outside of the electric heating membrane. The heating container can be made into various sizes and shapes to make the electrothermal pots with various uses. The electrothermal tile pot reduces the generation of some physical or chemical changes between the metallic material and the food in the process of cooking the food, thus the utility model has the advantages of high quality, long service life, and high safety. The utilizing rate of the electrical energy is high, and the utility model is suitable for cooking the food with the long cooking time, the soup, the thick soup, and the high-grade nutriment.
Description
The present invention relates to a kind of electric food warmer, particularly Electrothermal tile pot.
Existing electric food warmer uses aluminium or some alloy material to make heating container: because these metal materials with food some physics or chemical change do not take place unavoidably in digestion process, to reduce the cooking quality of food usually.So general citizen get used to using the traditional tile pot to digestion time long some soup custard or some senior tonics, to keep the original local flavor of food.
The electric heating body of prior art uses heating wire or usually by its electrothermal tube of making, ribbon heater, adopt mica or quartzy as insulation heat transfer matter, since the heat generation rate low (40～60%) of this electric heating body, service life short (about 1000 hours), complex manufacturing, the cost height.Existing some electric cooker, electric frying pan uses for convenience, makes split or structure, and the conduction of the heat from the electric heating body to the heating container is not direct like this, has reduced utilization rate of electrical.
The object of the present invention is to provide a kind of improved electric food warmer, it can improve the cooking quality of food, improves utilization rate of electrical, increases the service life, and is safe in utilization.
The object of the present invention is achieved like this: it adopts heat-resistant insulation materials such as pottery, glass, enamel to make heating container; the chemical thermo electric material that utilizes Liu Dazhong to succeed in developing recently---Electric radiant Heating Film replaces heating wire; metallic conductor is made extraction electrode on the outer surface of heating container is fixing; coat the air-dry back of Electric radiant Heating Film liquid and become Electric radiant Heating Film, add insulating protective layer.
Electric food warmer of the present invention is owing to make heating container with heat-resistant insulation material, some physics or chemical change that metal material takes place with food have been reduced in the digestion process of food, improved the cooking quality of food, simultaneously owing to use Electric radiant Heating Film to make electric heating body, improved the electric thermal efficiency (80～94%), prolonged the service life (about 8000 hours) of electric food warmer, this electric food warmer can be made various branch body structures easy to use as required, because at this moment Electric radiant Heating Film is the outer surface that directly is attached to heating container, the heat conduction has directly improved utilization rate of electrical greatly.
Fig. 1 is the profile of electric food warmer of the present invention.
The enforcement of electric food warmer of the present invention is described below in conjunction with Fig. 1:
At wall thickness is that high temperature insulation container outer wall (1) between 0.15～0.6 centimetre is gone up metallic conductor admittedly and made extraction electrode (2), coats the air-dry back of Electric radiant Heating Film liquid again and becomes Electric radiant Heating Film (3) (power is 0.1～20 watt/centimetre
2), outside it, add insulating protective layer (4), put shell body.Connect the power connection on the shell body after the control circuit of the electrode that heating container is drawn and prior art and indicating circuit connect again.The using method of this electric food warmer is identical with existing electric food warmer, as long as food is put in the heating container, connects power supply and just can carry out boiling.
Claims (2)
1, electric food warmer; by heater, heating container, control circuit; formations such as shell body; feature of the present invention is that its heating container is made by heat-resistant insulation material; its heater is that metallic conductor is done extraction electrode on the outer surface of heating container is fixing; coat the air-dry back of Electric radiant Heating Film liquid and become Electric radiant Heating Film, add insulating protective layer.
2, according to claim 1,2 described electric food warmers, the wall thickness that it is characterized in that heating container is 0.15～0.6 centimetre.
