Description

Multipurpose electrothermal pot

The utility model relates to a kind of electric food warmer of domestic cookers.

The domestic electric heating cooker is of a great variety, adopt the most general have electric cooker, electric frying pan, electric chafing dish, electric oven etc., they all are the electric-heating cooking utensil of special purpose basically, promptly be subjected to the restriction of its Mechanical Builds, the function of every kind of pot is corresponding with its title basically to be a kind of special-purpose pot, be applicable to respectively cook rice over a slow fire, cooking, the instant-boiled mutton, baked food, in general can not the phase trans-substitution general.Their structure mainly comprises pot cover, pot body and electric heater unit, and pot cover cooperates with a pot body and is buckled in above pot body, and electric heater unit is installed in the bottom of pot body.Electric heater unit generally adopts electric hot plate, is with electrothermal tube or heating wire and so on heating element heater die casting or is installed in the stone or metal plate for standing a stove on as a precaution against fire, is rigid structure, and heater and pot body are for dividing a body structure.Electric cooker also has a soft magnet temperature regulating device, it by twice temperature control respectively with heating and temperature control below 105 ℃ and 70 ℃.The deficiencies in the prior art part is: 1. electric heater unit is a split-type structural with the pot body, and is rigid member, and both can not well coincide, directly contact, and the corresponding temperature difference is big, and the thermal efficiency is low.2. the moulding and the mode of heating function single with it of pot body adapt, and a kind of pot can only a kind of purposes.3. thermostat generally is to be fixed on the heating plate, and what reflect, control is the temperature of heating plate, with the pot body certain gap is arranged, and not accurate enough, the temperature control amplitude is big.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of have multiple function, electro heating multipurpose pot product that versatility is good are provided.

Can reach the purpose of this utility model by following measure.The pot system becomes the revolving body shell vessel of the bottom of a pan radius much larger than pot body radius; Its heater adopts the open type thin film heater, and links together with the pot body, keeps excellent contact; It also has thermosistor, and thermosistor, pot body, heater three are connected.

Below in conjunction with accompanying drawing, embodiment content of the present utility model is described in further detail.

Fig. 1, electro heating multipurpose pot organigram;

Fig. 2, electro heating multipurpose pot electrical schematic diagram.

Among the figure: (1) pot cover; (2) pot body; (3) thermosistor; (4) thermal sensitive piece; (5) thermal element; (6) thermal insulation board; (7) pressing plate; (8) support; (9) power line; (10) handle; (K ₁) thermosistor (being part 3); (D) neon bulb; (R ₁～R ₃) heating wire in the open type thin film heater; (K ₂) step switch; (R ₄) the neon lamp dropping resistor.

The revolving body shell vessel structure of the bottom of a pan radius much larger than pot body radius taked in the moulding of pot body (2), as radius 1000mm in the bottom of a pan in Fig. 1 example, and pot body radius 60mm; Pot height 60mm, bore 280mm.From the pot figure modelling make that it has frying pan, the general character of cook rice over a slow fire pot, Baking pan, chafing dish etc., general may.Consider many-sided reason, the pot body adopts a ferrous material to be fabricated to, other aluminium, copper, alloy also can, and be coated with the far infrared coating in the pot bottom appearance, improve the thermal efficiency; Its pot cover is similar to the pot shape, is the revolving body shell-like structure of a left-hand thread, to enlarge volume, adapts to the space requirement that steaming and so on food is made.Settle handle then to constitute fixed in pot body bilateral symmetry and use pot more; Handle in this example (10) but be to be the convenience type that demolition is connected with pot body stent to use pot more, setting up handle, removing pot cover is exactly round-bottomed frying pan, removing that handle places on the dining table is chafing dish, other state can be selected arbitrarily as required.

Electric heater unit (5) adopts the open type thin film heater, and links together with the pot body.Thin film heater belongs to soft heater, can adapt to the shape in the bottom of a pan and possible thermal deformation thereof preferably.It is fastened on the bottom of pot body by thermal insulation board (6), pressing plate (7) and press strip and so in this example, even the tabular thin film heater tightly is attached on the bottom of a pan face that scribbles coating, guarantees that the good conduction of heat gives a pot body.Thermal insulation board can adopt the material manufacturing preferably of asbestos board, perlite, rock wool and so on heat-proof quality, and pressing plate, press strip mainly play and compress, be connected and fixed effect, and common metal plate, bar get final product, and is connected with a pot body with screw.

Thermosistor (3) (K in the electrical schematic diagram ₁) adopt that existing product gets final product on the market, its effect is to select, the temperature of control heater.For making temperature control more accurate, between thermosistor, pot body, heater, be provided with thermal sensitive piece (4), effectively the three is coupled together, thermal sensitive piece is the sheet of strip aluminium or copper and so on good heat conductivity, its upper surface pastes mutually with the part in the bottom of a pan, and its lower surface pastes mutually with the part of heater, and an end is connected with thermosistor, make three's temperature accurately consistent, the temperature control amplitude is little.By thermal sensitive piece the temperature of the bottom of a pan, heater is in time passed to thermosistor, when reaching, thermosistor gives when selecting temperature, just auto power off, temperature of boiler drop to give select temperature following after, thermosistor is connected power supply immediately automatically, the switching electricity reaches the constant temperature effect repeatedly, and is provided with indicator lamp (D), in order to instruction heater power on/off situation.Temperature can give choosing, also can in use stepless on demand setting.Generally cooking is optional is adjusted to 250 °～300 ℃; Steamed sweet bun, stewing rice are recruited 105 ℃, and keeping warm mode can be selected 75 ℃ for use; The instant-boiled mutton can be recruited more than 100 ℃, available about 150 ℃ of other pancake, lightly fried dumpling and so on.Available step switch (K ₂Transform power cooperates thermostat to reach optimum efficiency or replaces thermostat realizes the temperature control purpose.

The relative prior art of the utility model has following advantage:

1. strong adaptability, all row are fried in shallow oil, fry, boil in a covered pot over a slow fire, boiled to multi-purpose pot, also has the function of chafing dish, baking pan, uses very convenient.

2. thermal efficiency height, comparable general electric food warmer is energy-conservation about 30%, and temperature control is accurate.

3. simple in structure, handsome in appearance.
