Technical field
The utility model belongs to the cooker technical field, is specifically related to electromagnetic induction heating and makes electromagnetic induction heating cookers such as the interior pot of electric cooker that heating is cooked or other similar electric pressure cooking saucepan.
Background technology
Electromagnetic induction heating type electric cooker (IH heating electric rice cooker) produces the magnetic line of force by energising back in the solenoid, and electromagnetic induction makes and places the interior pot of pot body to flow through eddy current, and rice is boiled in the pot heating in making.
Induction coil in the electromagnetic induction heating type electric cooker is wound in bobbin, can both thermally equivalent and heating for pot bottom in making and side, improve the mouthfeel of rice and other food, at the outer bottom place and the outer arcuate face place of bobbin.Outer arcuate face place is the spiral bobbin that is wound in of at least two group batch (-type)s; In actual production process, the coiling efficient of outside cambered surface place helical winding at intermittence is low, and coil is through being everlasting around getting loose again to a segment distance; Cause processing repeatedly; Increased processing cost, simultaneously, the potential danger that the product that processes in use also has coil to get loose, upspring.
The utility model content
The defective low for overcoming prior art coil winding efficient, that coil is prone to get loose, processing cost is high, the utility model provide that a kind of coiling efficient is high, coil location firmly, a kind of electromagnetic induction heating electric rice cooker of reducing of processing cost.
To above essential technique problem, the corresponding technical solution scheme of the utility model is:
A kind of electromagnetic induction heating electric rice cooker; Comprise pot body, control circuit, interior pot, bobbin and induction coil; Said bobbin is arranged in said pot body, and said induction coil is wrapped on the said bobbin and through electromagnetic induction and makes said interior pot heating, and said interior pot is placed in the body of stewing; Said induction coil is connected with said control circuit; It is characterized in that said bobbin comprises bottom and side surface part, spiral is wound into said side surface part to said induction coil from said bottom, and the said at least side surface part of said bobbin is provided with some location buckles that are used to locate said induction coil coiling trend.
Further, said induction coil twines two circles at least on said side surface part, and on every circle, distributing is intervally distributed with some said location buckle.
Further, said location buckle comprises horizontal location portion that is used for the coil winding location and the connecting portion that is used for the connecting coil frame.
Above-mentioned location buckle, its horizontal location portion is flat or hook-shaped.
Preferably, the location buckle is L word shape.
Further, from art designs and technological pluses and minuses aspect that processing and manufacturing influenced, said location buckle is the protruding stupefied of the helix shape that forms on the said bobbin, and said coil winding is in the track of said protruding stupefied formation.
Further, be during said coil winding and equidistantly distribute, or the distribution of gradually dredging by bottom coil equidistance, side surface part; Or dredge gradually, close on that side surface part is gradually close to the outer ring from the center by bottom coil, the bottom-up equidistance of side surface part or the distribution of gradually dredging.Distribution mode overcomes the coil kindred effect, and the magnetic field of generation is even, and a pot body is heated evenly.
For reducing the skin effect, induction coil is formed at least two leads.
The lead of coiling induction coil in the utility model, during coiling, it is intermittently spiral between the adjacent wires circle, to leave being called of big gap, and tight or little space are plane formula between the lead.
The utility model is with respect to the electromagnetism heating electric rice cooker of prior art, and its beneficial effect is:
1. at the screw type increase buckle at intermittence of bobbin outside cambered surface, make coil, guaranteed the feasibility of processing greatly and improved efficient whenever around just having corresponding buckle that it is fastened to certain distance.
2. spiral induction coil cooperates the bottom of a pan convex globoidal external form, and the pot heating area increases in making, and the thermal efficiency improves greatly.
3. include intermittently spiral solenoid during the lead coiling, its leave the certain interval radiating effect obviously, low cost of manufacture, work safety, reliable and stable and realize the big heating surface area of pan.
Description of drawings
Fig. 1 is the coil holder structure sketch map;
Fig. 2 is the cut-away view of bobbin;
Fig. 3 is a buckle and the sketch map that is connected of coil.
The specific embodiment
A kind of electromagnetic induction heating electric rice cooker; Comprise pot body, interior pot, bobbin 1 and induction coil; Bobbin is arranged in electric cooker pot body; Induction coil is wrapped on the bobbin and through electromagnetic induction and makes interior pot heating, and interior pot freely is placed in pot body, and induction coil is connected with the electric cooker control circuit.
Said bobbin comprises bottom and side surface part, and spiral is wound into said side surface part to said induction coil from said bottom, and the said at least side surface part of said bobbin is provided with some location buckles 2 that are used to locate said induction coil coiling trend.
Induction coil comprise the bottom coil 3A of bottom faces coiling and the outside cambered surface that is connected on the side surface part coil 3B of coiling form; Spiral is wound into side surface part to induction coil from the bottom, and said side surface part comprises the side that the bottom stretches out into convex globoidal and/or makes progress with the convex globoidal continuity.
Be during said coil winding and equidistantly distribute, or the distribution of gradually dredging by bottom coil equidistance, side surface part; Or dredge gradually, close on that side surface part is gradually close to the outer ring from the center by bottom coil, the bottom-up equidistance of side surface part or the distribution of gradually dredging.
