Abstract

The invention discloses an electric rice cooker composed of a pot cover 1, an outer pot 2, a middle pot 3, an inner pot 4, a heater 5 and a temperature control system 6; the inner pot is made of steel glass, or quartz glass, or ceramic, or general steel plate; an enamel is burned or a non-sticky coating is sprayed to the surface of the inner pot made of the general steel plate; and the inner pot does not contact the heater. Because the inner pot made of various different materials makes the electric rice cooker obtain the beneficial effects of low price, easy washing, firmness, durableness and the like, the demands of consumers on high cost performance, low price and high quality of such electric rice cooker are ensured.

Description

Electric cooker

The present invention relates to a kind of electric cooker.

Sell on the current market with family in the inner pan of electric cooker of cooking that uses, the overwhelming majority adopts aluminum alloy plate materials to make, the price of aluminum alloy plate materials is more expensive; Production cost is high; The selling price of product is just high, and intensity is also low, easy deformation; Be not durable, can not satisfy the consumer electric cooker cost performance height and cheap and good-quality demand.

The objective of the invention is to break the unicity of inner pan of electric cooker manufacturing materials kind, the various beneficial effects that pot produces in making with various different materials satisfy the consumer to electric cooker cost performance height and cheap and good-quality demand.

For realizing above-mentioned purpose; Electric cooker of the present invention is made up of pot cover, outer pot, middle pot, interior pot, heater and temperature control system, and interior pot is to use safety glass, or uses quartz glass; Or with pottery; Or make with the carbon structural steel steel plate, and interior pot do not contact with heater.

The above-mentioned interior pot outer surface made from the carbon structural steel steel plate has been fired enamel, has perhaps sprayed the Teflon, has perhaps sprayed non-sticking lining.So-called non-sticking lining has nothing in common with each other at the call of each different electric cooker manufacturer, and Su Boer is Tao Jing, and TCL cries black brilliant, and black boring named in the Glanz, and Pentium is named and bores brilliant or silver-colored crystalline substance.

The heater of electric cooker is a heat-generating pipe.

Be equipped with large sealing packing ring between the interior pot edge of the middle pot edge of middle pot and interior pot, the manufacturing materials of large sealing packing ring is a silicon rubber.

Be equipped with small sealing ring between the interior the bottom of a pan of the middle the bottom of a pan of middle pot and interior pot, the manufacturing materials of small sealing ring is a silicon rubber.

The interior pot of electric cooker is used safety glass; Perhaps quartz glass, perhaps pottery is made, or adopts the carbon structural steel steel plate to make to reburn and process enamel; Safety glass, quartz glass all are transparent; Pottery or enamel can be selected pure white color for use, will let the consumer time be easy to see clearly whether wash clean of Chu in washing like this, use relievedly; The manufacturing materials of interior pot adopts after the carbon structural steel, and the carbon structural steel steel plate is more cheap than aluminium sheet, can reduce production costs, and makes the selling price of product cheap, reduces consumer's life spending; The strength ratio aluminium sheet of steel plate is high, and the product of making is durable; Steel are heavier than aluminium, and the interior pot of making is important, make the consumer feel steady and sure at heart in hand held; After interior pot appearance spraying Teflon or the non-sticking lining, both beautiful, antirust again; Glutinous rice not again; Clean easily, the consumer can be willing to accept, so; The different beneficial effect that pot produces in making with various different materials, just satisfied the consumer to the electric cooker cost performance high and cheap and good-quality demand.

When the electric cooker that uses electric hot tray not contact with interior pot is cooked; It is the same in food steamer the inside steamed rice that the heating status of interior pot just is similar to; It is just even relatively to be heated, and has avoided the interior pot of the low material of the various thermal conductivity ratio aluminium alloys of above-mentioned usefulness to boil paste to rice; Also avoided low with thermal conductivity factor, the interior pot of the material of also enbrittling simultaneously produces embrittlement.

The present invention can adopt that heat-generating pipe simple in structure replaces selling on the current market with family in the sort of structure more complicated that all generally adopts of most of electric cookers of using; Processing technology is also complicated; Also to use the heater of the more expensive aluminum alloy materials of price, can further reduce the production cost of electric cooker.

Adopt heater not contact after these technical measures with interior pot, its cost input is 0; And this technology goes for the most cheap fully, the common electric cooker of minimum retaining, therefore, the product of producing, be one can be towards the hugest consumer group, that everybody affords, use comfortablely product.

The application of large sealing packing ring and small sealing ring can reduce heat runs off, and can reach the beneficial effect of energy savings, can save consumer's spending.

Also have, sell on the current market with family in the electric cooker that uses in use because the thermograde of the inside, electric hot tray temperature field is maximum; Temperature Distribution is least uniform; In the heat accepted of the near grain of rice of high-order bit distance of pot the inside and electric hot tray temperature just many, just boiling at first, water absorption is just many; Will make that part of rice boil very mashedly, mouthfeel is bad.When the electric cooker that the present invention uses electric hot tray not contact with interior pot was cooked, it was the same in food steamer the inside steamed rice that the heating status of interior pot just is similar to, and it is just even relatively to be heated; The grain of rice of pot the inside is heated and absorbs water also even; Also just successfully overcome for a long time, electric cooker always has local rice to be boiled very mashedly when cooking, the drawback that mouthfeel is bad; Rice has been fond of eating, and has also just improved consumer's quality of life; Simultaneously, the consumer again needn't worry time that electric cooker uses one long after, the puzzlement that pot temperature field temperature inside skewness was brought in the distortion of the interior pot the bottom of a pan and electric hot tray can make.

Below in conjunction with accompanying drawing and embodiment the present invention is done further explain:

Fig. 1 is the schematic cross sectional views of first embodiment of electric cooker of the present invention.

Fig. 2 is the schematic cross sectional views of another embodiment of electric cooker of the present invention.

Electric cooker shown in Figure 1 is made up of pot cover 1, outer pot 2, middle pot 3, interior pot 4, heater 5 and temperature control system 6; Pot cover 1 flexibly connects with hinge with outer pot 2; Middle pot 3 places outer pot 2 the insides, and interior pot 4 places pot 3 the insides, the heating temperature of the interior pot 4 of temperature control system 6 controls; Heater 5 places between pot 3 and the interior pot 4, does not contact with interior pot 4.

The difference of Fig. 2 and electric cooker shown in Figure 1 be to adopt a heat-generating pipe 7 replace Fig. 1 when shown in, sell on the market with family in the sort of heater 5 that all generally uses of most of electric cookers the inside of using, heat-generating pipe 7 do not contact with interior pot 4 yet; Simultaneously, between the supporting surface of the middle pot edge 31 of middle pot 3 and interior pot 4 interior pot edge 41, be equipped with large sealing packing ring 8; Between the interior the bottom of a pan 42 of middle pot 3 the middle the bottom of a pan 32 and interior pot 4, be equipped with small sealing ring 9.
