A groove and a through hole are arranged on the holding disk (3), and the electric-heating pipe (4) is inlaid in the groove of the uniform-heating plate (3). The utility model is characterized in that whole surfaces of the uniform-heating plate (1) and the holding disk (3) are welded into integration. The utility model has the advantages that the conductive coefficient is more than 190, the heat efficiency is more than 95 percents, the extreme operating temperature is above 600 DEG C, the power is adjustable, etc. The compound electric-heating disk is particularly suitable for the heating element of an electric-pressure cooker.
Description
A kind of combined type electric heating plate belongs to family expenses electric cooking appliance electric heating plate.
Present family expenses electric cooking appliance electric heating plate, mainly contain cast-in, inserted two kinds, cast-in divides cast aluminium formula or cast iron type again, and cast-in moulding process is to be cast on the electric heating tube melting good aluminium or iron after the electric heating tube coiling, again through the cut moulding; Cast aluminium formula conductive coefficient is high by about 140, though fusion temperature is higher than cast iron type at 560-580 ℃ of conductive coefficient, the subject matter that exists is the phenomenon that high temperature high power just is prone to the fusing of aluminium dish, is used in small-power low temperature; Therefore cast iron type occurred, moulding process is with the cast aluminium formula, although realized high temperature resistant high-power use, the subject matter that exists is that conductive coefficient is low by about 50, and pig iron fusion temperature increases technology difficulty up to 1400 ℃, wastes a large amount of energy.Inserted is earlier the aluminium dish to be cast out, and electric heating tube is mounted in the groove of aluminium dish again, and conductive coefficient, fusion temperature, the scope of application are all with the cast aluminium formula.For the problem the applicant's research and design that solves above-mentioned prior art existence goes out electric heating plate, and apply for a patent, its application number: be 91211169, the applying date: 910124, utility model title: electric heating plate, the outstanding problem that solves of electric heating plate of the present utility model is that traditional integral type is changed into combined type, be that the high aluminium sheet of conductive coefficient is adopted on top, the centre is an electric heating tube, the bottom be the compound rivet welding of iron plate together, this electric heating plate has solved effectively that the aluminium dish can not be applied to high temperature high power in the prior art, cast iron type fusion temperature height, the problem that wastes energy, but the subject matter that exists is rivet welding is that the point type welding still has the slit, in conjunction with defective tightness, influences heat-transfer effect.
The purpose of this utility model just is to overcome the deficiencies in the prior art, provide a kind of moulding process to simplify, save a large amount of energy greatly, alleviate labor strength and work situation, have that conductive coefficient is high more than 190, the heat efficiency is up to more than 95%, working temperature limit is more than 600 ℃, and the combined type electric heating plate of adjustable power.
The purpose of this utility model realizes in the following way:
This combined type electric heating plate comprises soaking plate 1, pallet 3, electric heating tube 4, and fluted and through hole on the pallet 3, electric heating tube 4 are embedded in the groove of pallet 3, it is characterized in that: soaking plate 1 is welded as a whole with pallet 3 whole faces.
The purpose of this utility model also can realize in the following way:
Described combined type electric heating plate is characterized in that: electric heating tube 4 is circular double wall electric heating tube under going up of shaping is flat, and the centre is a heating wire, skin is an iron pipe, outermost layer is an aluminum pipe, and aluminum pipe is flat circular down through being shaped as, and soaking plate 1,3 on pallet are coated with solder layer 2.
Described combined type electric heating plate is characterized in that: described soaking plate 1,3 coated solder layers of pallet, 2 the bests are the lead welding bed of material, also can adopt the solder layer of other materials.
Described combined type electric heating plate is characterized in that: described soaking plate 1 is for aluminium sheet, pallet 3 are steel plate, and adopting corrosion resistant plate be the best, processes corresponding grooves according to the group number of electric heating tube on the pallet 3 and terminal is drawn through hole.
Described combined type electric heating plate is characterized in that: there is one or more fixed screw in described pallet 3 outsides.
Described combined type electric heating plate is characterized in that: described electric heating tube 4 can be a group or more.
Combined type electric heating plate of the present utility model, it is improvement to the applicant's 91211169 electric heating plate patents, the outstanding contributions of this combined type electric heating plate are, by changing welding manner, whole the composite welding that has realized soaking plate and pallet is as a whole, solve former rivet welding for the some contact, the slit has still been arranged, influenced the problem of heat-transfer effect; Although this combined type electric heating plate is to have two kinds of materials to be composited, owing to adopt advanced welding procedure, making two kinds of material fusions at soaking plate 1 and 3 coated solder layers of pallet when heating welding is one.This combined type electric heating plate compared with prior art, have: moulding process is simplified, is saved a large amount of energy greatly, alleviates labor strength and work situation, conductive coefficient height (reaching more than 190), heat efficiency height (reaching more than 95%), working temperature limit is more than 600 ℃, and advantages such as adjustable power, can be widely used in electric-heating cooking utensil and make heating element, be used in the heating element of electric pressure cooker especially, be present more satisfactory combined type electric heating plate.
Fig. 1 is that combined type electric heating plate structure of the present utility model is cutd open and shown schematic diagram;
Fig. 2 is that combined type electric heating plate of the present utility model is looked up structural representation;
Among the figure: 1 soaking plate, 2 solder layers, 3 pallets, 4 electric heating tubes, 5 electric heating tube leading-out terminals.
Fig. 1-2 is a combined type electric heating plate most preferred embodiment of the present utility model, below in conjunction with accompanying drawing combined type electric heating plate of the present utility model is described further:
Shown in Fig. 1-2, the moulding process of combined type electric heating plate is: soaking plate 1 adopts aluminium sheet stand-by with the die stamping blanking forming, electric heating tube 4 overcoats are loaded onto aluminum pipe, the machine that bends bends, the shaping of forcing press die pressure, double wall electric heating tube outer wall is made into flat circular stand-by down, behind the soaking plate 3 usefulness corrosion resistant plate die stamping blankings, through extending, punching, indent, after the three processes respectively, electric heating tube 4 is embedded in pallet 3 grooves, and electric heating tube 4 binding posts are drawn from the hole, coated solder layer 2 on the plane that pallet 3 and electric heating tube 4 are formed, solder layer 2 is a kupper solder, the pressure welding moulding of heating above again aluminium pallet 1 being placed on.
