Embodiment
Hereinafter, with reference to accompanying drawing, the preferred embodiment of the present invention is described.
The induction heating vessel 1 of present embodiment possesses: the container body 2 formed by non-conductive material; Be installed on container body 2 and the induction heating body 3 of the induction heating based on electromagnetism cooking pot can be realized. Container body 2 has the sidewall erected, the surrounding of this side walls enclose inner bottom surface 21, the aqueous heating objects such as water can be held wherein, induction heating body 3 is arranged on inner bottom surface 21 side of such container body 2.
Induction heating vessel 1 puts using of the electromagnetism cooking pot commercially sold usually above. It can thus be seen that the inner bottom surface 21 of container body 2, the size of induction heating body 3 of inner bottom surface 21 side that is arranged on container body 2 are not particularly limited, can set according to the size of the electromagnetic induction heating coil that the electromagnetism cooking pot used possesses. Such as, its internal diameter of general electromagnetic induction heating coil that possesses of home-use electromagnetism cooking pot sold on market is about 5cm, external diameter is about 20cm, as long as the coil of work, also there is the coil bigger than this, can suitably determine size according to the electromagnetism cooking pot that imagination uses.
The shape of the inner bottom surface 21 of container body 2 is not defined as illustrated square shape yet. Such as, except being set to rectangular shape, round-shaped except, it is also possible to be set to the polygonal shapes such as triangle, pentagon, hexagon. The shape of the entirety of container body 2 also can be considered grade easy to use and be set to different shape.
The induction heating body 3 being installed on container body 2 is made up of the duplexer of the hot sealing layer (heat-sealinglayer) 31 comprising conductive layer 30 and having heat sealability relative to container body 2, wherein, the high frequency magnetic field that the electromagnetic induction heating coil that conductive layer 30 is possessed by electromagnetism cooking pot etc. produces and induce eddy current, and this conductive layer 30 is by because resistance produces joule heating, the conductive material that generates heat is formed (reference Fig. 5, Fig. 6 and Fig. 7).
As the conductive material forming conductive layer 30, the various conductive materials that such as metals such as aluminium, nickel, gold and silver, copper, platinum, iron, cobalt, tin, zinc or their alloy etc. can be used to generate heat because of the induction heating under high frequency magnetic field effect are formed. It is believed that such as, when aluminium is used as conductive material, it is preferred to use the aluminium foil of 0.10��100 ��m of left and right thickness forms conductive layer 30, it is more preferable to the aluminium foil of 1��40 ��m of left and right thickness can be used to form conductive layer 30.As long as using the tinsels such as aluminium foil to form conductive layer 30, just can when induction heating body 3 be installed on container body 2, the three-dimension process of the sidewall bending etc. easily induction heating body 3 is implemented the inner bottom surface 21 along container body 2, being erected on around inner bottom surface, thus make it suitable for the shape of container body 2.
As long as the material that hot sealing layer 31 respective container main body 2 has heat sealability is not just particularly limited to, suitably can select according to the non-conductive material forming container body 2. Preferably easily formed machining, heat sealability are good and have the resin of suitable thermotolerance, it is particularly preferred to the resin of container body 2 identical type described later. Stacking conductive layer 30 and hot sealing layer 31 directly or can be come by known lamination via suitable tackiness agent. By making induction heating body 3 be configured to duplexer such that it is able to apply the manufacturing technology of known multilayer film, multilayer tablet, so its manufacture will be easy to.
As the non-conductive material forming container body 2, it is possible to be suitable for using the synthetic resins materials such as polyolefin-based resins, polyamide-based resin such as the polyester based resin such as polystyrene resin, polyethylene terephthalate, polypropylene such as polystyrene. Container body 2 can be individual layer or with these resins each other or the multilayered structure that combines of other functional resins. As non-conductive material, it is also possible to make paper using, glass etc., but consider the heat sealability between the hot sealing layer 31 of induction heating body 3, it is preferable that press at internal surface layer or apply aforesaid synthetic resins. By forming container body 2 with these materials, just can realize, to provide at a low price, the induction heating vessel 1 employing the heating cooking of electromagnetism cooking pot.
In the present embodiment, induction heating body 3 has the flat principal part of circular, and is provided with from the fusing function portion 32 (with reference to Fig. 4 and Fig. 8) that such principal part radially erects. For the shape of induction heating body 3, although from the characteristic of the eddy current induced, circular efficiency is best, but can also be set to square shape, rectangular shape etc. corresponding to the shape of container body 2.
The principal part of induction heating body 3 is divided into central part region CF, main heating region HF and region, circumference OF by cutting line 33a, 33e that conductive layer 30 circumferentially cuts into concentric circles. Further, main heating region HF is divided into multiple region (with reference to Fig. 1 and Fig. 6) by same cutting line 33b, 33c, 33d.
By forming such cutting line 33a, 33b, 33c, 33d, 33e, the eddy current induced at conductive layer 30 would not flow through on the direction crossing cutting line 33a, 33b, 33c, 33d, 33e. Thus, in each region that cut-off line 33a, 33b, 33c, 33d, 33e divide out, eddy current is induced.
Eddy current is sensed according to the shape of the electromagnetic induction heating coil of electromagnetism cooking pot, so the eddy current being usually induced at central part region CF is not so strong, sometimes the distribution of current density can be unstable slightly, thus interference flows through the eddy current of more lateral. Therefore, it is divided into central part region CF and main heating region HF by cutting line 33a, it is possible to reduce the impact on main heating region HF.
In addition, the electric current distribution of the eddy current being induced diametrically and uneven one, there is slightly by the position of periphery the peak value of current density than radial central authorities, the position of the correspondence of conductive layer 30 is imposed heat.Therefore, for main heating region HF is divided into multiple region cutting line 33b, 33c, 33d, compared with impartial the situation configuring these cutting lines diametrically, it is preferable that in the position of more outer circumferential side, cutting line is set closelyer, so that eddy current is not concentrated in the position of outer circumferential side. Thus, just can adjust the eddy current induced and realize heating equalization.
Like this, cutting line 33a, 33b, 33c, 33d, the 33e circumferentially conductive layer 30 being cut into concentric circles by being formed, the eddy current that adjustment conductive layer 30 induces, heat impartially, thus suppress heating uneven, the aqueous heating objects such as water can not sharply be heated by local, thus can suppress the prominent generation boiled. Further, the starting point when end edge of cutting line 33a, 33b, 33c, 33d, 33e is the aqueous heating object boilings such as water and produces bubble. Therefore, continue time when heating as put into zeolite to generate a large amount of small bubbles, also have the effect preventing from unexpectedly producing big bubble, also inhibits the prominent generation boiled like this.
Consequently, it is possible to avoid the situation because the prominent heating object boiled and disperse makes user be burnt, or allow to the situation of avoiding electromagnetism cooking pot periphery contaminated.
In addition, the cutting line 34a circumferentially extended diametrically than cutting line 33a central part region CF more in the inner part is divided into multiple. Equally, the cutting line 34c that more more outward than cutting line 33e circumference region OF is circumferentially extended diametrically is divided into multiple. By in a circumferential direction these Region dividing being become multiple, thus can not inducing the strong eddy current at the center of the electromagnetic induction heating coil possessed around electromagnetism cooking pot, each region being divided into multiple zonule would not become so high temperature. Therefore, as long as sealing with the hot sealing layer 32 in these regions CF, OF, induction heating body 3 being installed on container body 2, just can suppress to conduct heat to container body 2, it is possible to prevent the damage of container body 2.
In addition, in the present embodiment, even in the region between cutting line 33b, 33c being formed in main heating region HF, also it is divided into multiple in a circumferential direction by the cutting line 34b extended diametrically, suppress the heating in this region, realize the heat-sealing with container body 2 by the hot sealing layer 32 in this region.
Like this, it is not only the central part region CF and region, circumference OF of induction heating body 3, the region suppressing heating is also form in the region between cutting line 33b, 33c of main heating region HF, realized and the heat-sealing of container body 2 by the hot sealing layer 32 in this region, thus can effectively suppress by the convection current of heating target thing, flowing or and electromagnetic induction heating coil between the floating of induction heating body 3 that causes of repulsion or fluctuation, it is possible to carry out more stable heating.
When forming these cutting lines, it is possible to by cutter from the enforcement hemisection of conductive layer 30 side, or use YAG laser, semiconductor laser etc. optionally to cut off conductive layer 4. Using induction heating body 3 as in the scope had no problem to biding one's time of one, cut-out can feed through to a part for hot sealing layer 31, due to by be set to not cut off hot sealing layer 31 but be connected state using induction heating body 3 as integrally treating, so manufacture time process will be very easy to.
In addition, the fusing function portion 32 radially erected from the principal part of induction heating body 3 is configured to: when carrying out heating cooking, in the process reduced gradually in the boiling of aqueous heating object, when the heating object in container become to become less than not holding heating object during predetermined amount or in container and unrealized heat movement to heating object empty burn state time, optionally generate heat position that is excessive and that rupture. By arranging such fusing function portion 32, it is possible to prevent empty burning, maybe can control heat-up time.
