Abstract
The utility model relates to a composition type electric heating disc, which is composed of a metal tray 1, tubular electric heating elements 2, 4, filling materials 3, a lead-out bar 5, and a fixing screw 6. The tubular electric heating elements 2, 4, are fixed in the metal tray in a suspending mode by a screw 6. The filling materials 3 are filled around the electric heating elements 2, 4, and are pressed into form. The upper surface is a flat surface or a cambered surface which is suitable for tightly contacting with various electric heating cookers. One layer of far infrared coating or a metallic layer 7 with low melting point can be sprayed. The electric heating disc has the advantages of high thermal efficiency, long service life, a lot of power shifts, low cost, and suitability for mechanized mass production. The utility model is the electric heating disc used on electric heating appliances, such as electric heating cookers, electric heating warmers, electric heating desicators, etc.
Description
The utility model relates to a kind of electric hot tray, especially for the electric hot tray of electric-heating cooking utensil.
The existing electric hot tray that is used for electric-heating cooking utensil, a kind of is that tubular electrothermal element at high temperature is cast in aluminium alloy or the cast iron base, processes through machine cut, brill pincers again.Another kind is to become blank with aluminium alloy or cast iron casting earlier, again the tubular electrothermal element embedding is pressed into groove and forms after machine cut fine finishining.Adopt above method moulding electric hot tray cost height, percent defective is big, the life-span is low, more be unfavorable for producing in enormous quantities.
The purpose of this utility model provides a kind of heat efficiency height, the life-span is long, cost is low, many power, and raw materials consumption is few, and is beneficial to the combined type electric hot tray of production in enormous quantities.
For reaching above-mentioned purpose, the utility model is realized in the following way, metallic plate punching is become the pallet similar to the electric hot tray shape, tubular electrothermal element is outstanding solid in pallet by screw, add inserts all around based on metal dust, repressed moulding, its upper surface is suitable plane or the cambered surface that closely contacts with various electric-heating cooking utensils.
The combined type electric hot tray of the utility model is compared with common electric hot tray, and have the following advantages: 1, cost is low, is convenient to produce in enormous quantities.Because the combined type electric hot tray of the utility model mainly is to adopt cast iron powder, fire clay, adhesive to mix compacting and moulding, need not machine cut, bore pincers processing and can obtain qualified finished product, thereby, processing and fabricating convenience, no waste product, cost are very low, only being 1/4th of aluminium alloy electric heating dish cost, is 1/2nd of embedding pressure type cast iron electric hot tray cost.
2, product heat efficiency height, the life-span is long.Because the electric hot tray of the utility model adopts the metal dust compacting to form, the contacted upper surface of electric hot tray and electric-heating cooking utensil can accurately be pressed into different shape, it is contacted well with electric-heating cooking utensil pot body, heat conduction is good, thereby heat efficiency height, simultaneously, avoided the influence of high temperature casting to the product electric property, thereby life of product is long, and electric property is stable.
3, the variable power class is many, and is easy to use.Because this electric hot tray is easy to process, can unsettled compacting advance 1-3 root tubular electrothermal element in the pallet, thereby can regulate many grades of power with the need arbitrarily.
Below, in conjunction with the accompanying drawings and embodiments the utility model structure is described further.Fig. 1 (a) and (b): the combined type electric hot tray structural representation that is applicable to the electric frying pan product.
Fig. 2: the combined type electric hot tray structural representation that is applicable to products such as electric rice cooker, electric food warmer, electric cup.
Fig. 3: the combined type electric hot tray structural representation that is applicable to electric frying pan and flat electric food warmer.
Embodiment one
A kind of combined type electric hot tray that is applicable to the electric frying pan product.As shown in Figure 1, this kind combined type electric hot tray is by metal tray 1, tubular electrothermal element 2,4, inserts 3, hold-down screw 6 constitutes, the metal tray 1 of present embodiment strikes out as shown in Figure 1 pallet shape by steel plate, high-power tubulose electric heating element 2, small-power tubulose electric heating element 4 is by 6 uniform unsettled being fixed in the metal tray 1 of screw, add on every side with cast iron powder and so on metal dust, fire clay and binding agent etc. mix the inserts of forming 3, compression moulding, make its upper surface be and the corresponding to concaved circular cambered surface of electric frying pan the bottom of a pan cambered surface, tubular electrothermal element 2,4 eduction rod 5 is fixed on the electric hot tray bottom, connects power circuit and uses.
Embodiment two
A kind of electric rice cooker, electric food warmer, electric chafing dish, electric cups etc. of being applicable to have the combined type electric hot tray of automatic temp controller product, its structure as shown in Figure 2, partly title, effect, mutual alignment concern identical with embodiment one for each, institute's difference is that metal tray 1 is hollow garden dish type, the upper surface of its electric hot tray is a hollow dimpling garden arcwall face, and hollow is partly placed the temperature-sensing element of automatic temp controller just.
Embodiment three:
A kind of combined type electric hot tray that is applicable to electric frying pan and so on frying pan, its structure as shown in Figure 3, each component names among the figure, effect, architectural feature are identical with embodiment one.The upper surface of different the is combined type electric hot tray of compression moulding is the plane.
As a kind of conversion of each embodiment of the utility model, the upper surface of described combined type electric hot tray is coated with one deck far ultrared paint or low-melting-point metal layer 7.(referring to Fig. 1,2,3)
As another conversion of the present utility model, described combined type electric hot tray also can make shapes such as garden shape except that embodiment one, two, three described various types, square, octangle, ellipse.The also available aluminium sheet of metal tray 1, zinc-plated plate stamping are made.Skin also can be coated antirusting paint 9.
The combined type electric hot tray of the utility model also can be used as the electric hot tray of electric boiling plate required on pharmacy industry, rubber manufacturing industry, the hot pressing hydraulic press, the electric thermal desiccator on the medicine equipment, electric heating device except that the electric hot tray that can be used as various electric-heating cooking utensils.
