  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[Induction cooking container]
First, a preferred embodiment of the induction heating cooking container according to the present invention will be described.
In addition, FIG. 1 is explanatory drawing which shows the outline of the induction heating cooking container which concerns on this embodiment, and has shown the container vertical cross section in the position corresponded to the AA cross section of Fig.2 (a) mentioned later.

  The container 1 shown in FIG. 1 is provided with an induction heating heating element 3 so as to face the bottom surface of the container body 2. When the induction heating heating element 3 is heated while being immersed in the injected water 7, 7 is provided with a steam generation chamber 21 in which steam is generated by boiling.

In the example shown in the drawing, the container body 2 has the bottom surface raised and inclined to the bottom, and the leg 2c extending substantially orthogonal to the inclination direction is provided on the grounding surface E side, thereby ensuring the horizontality of the entire container. It is supposed to be.
The container 1 is usually used by being placed on a commercially available electromagnetic cooker. However, by providing the container body 2 with the legs 2c, the container 1 is placed between the container 1 and the grounding surface E on the electromagnetic cooker. A gap 8 as shown is formed. And it is radiated by the air which circulates through this space 8, and heat can not be trapped between the container 1 and the electromagnetic cooker, whereby the temperature control mechanism works and the electromagnetic cooker stops. Or effectively lowering the output, and continuous heating at high output is possible regardless of the type of the electromagnetic cooker.

  Further, in the induction heating heating element 3 attached to the container body 2, an eddy current is induced by a high frequency magnetic field generated from an electromagnetic induction heating coil provided in an electromagnetic cooker or the like, and Joule heat is generated due to its electric resistance, thereby generating heat. Use conductive materials such as aluminum, nickel, gold, silver, copper, platinum, iron, cobalt, tin, zinc, etc., or alloys thereof, or conductive materials such as resin film or paper with conductivity. Can do. More specifically, for example, when aluminum is used as the metal material, the induction heating heating element 3 can be formed using an aluminum foil having a thickness of about 0.10 to 100 μm.

Further, in the illustrated example, the induction heating heating element 3 has a substantially circular shape, and is fixed to support portions 2 d formed to protrude from the bottom surface of the container body 2 at four locations near the outer edge portion. . In order to fix the induction heating heating element 3 to the support portion 2d, as shown in the drawing, the tip end portion of the support portion 2d is protruded from the slits 3b provided at four positions near the outer edge of the induction heating heating element 3, A fastener such as an e-ring or a ceiling may be fixed to the tip portion, but is not limited thereto. For example, in addition to folding or crushing the tip of the support portion 2d protruding from the slit 3b, a fastener such as a screw or scissors may be used, or it may be fixed by heat sealing or an adhesive. . Further, instead of the slit 3b, a cross, a star, or the like may be cut, and the contact area between the induction heating heating element 3 and the support 2d is reduced so that the heat conduction is reduced. Is preferred.
FIG. 2 is a plan view schematically showing a state in which the induction heating heating element 3 is attached to the container body 2.

If the induction heating heating element 3 is attached to the container main body 2 in this way, when the water 7 injected into the container main body 2 is boiled, the induction heating heating element 3 is not vigorously shaken by the generated bubbles. The induction heating heating element 3 can be fixed while applying an appropriate tension.
Further, most of the induction heating heating element 3 fixed to the support portion 2d is in a state of being lifted from the container main body 2 and is not in contact with the container main body 2. Therefore, the four corners of the induction heating heating element 3 are the container. Even if it is in contact with the support portion 2d formed on the main body 2, the influence of heat generated by the induction heating heating element 3 can be ignored, and damage to the container main body 2 due to heat can be prevented.

  Therefore, it is not necessary to consider the damage caused by the heat generated by the induction heating heating element 3 for the material forming the container body 2, and the same material as that conventionally used as a packaging container for frozen or refrigerated foods, etc. More specifically, polystyrene resins such as polystyrene, polyester resins such as polyethylene terephthalate, polyolefin resins such as polypropylene, synthetic resin materials such as polyamide resins, and various general-purpose materials such as paper and glass By forming the container body 2 from the nonmagnetic material, a low-cost induction heating cooking container that can be used in an electromagnetic cooker can be easily provided.

  In the illustrated example, the tray 41 is supported at the opening of the steam generation chamber 21 by the step 2 a formed along the inner periphery of the container body 2. Then, two cooking section defining members 42 and 43 are stacked above the tray 41, and further the cover 5 is placed on the upper part, thereby the first cooking section 4a, the second cooking section 4b, and the third cooking section. 4c is arranged so as to be superimposed on the steam generation chamber 21.

  Here, the cooking section defining members 42 and 43 have tray-like top plates 42a and 43a on which cooking targets are placed, and side wall surfaces 42b and 43b depending from the top plate. In the illustrated example, the lower end side of the side wall surface 43b of the cooking section defining member 43 positioned above is supported by the outer peripheral edge of the top plate 42a of the cooking section defining member 42 positioned below the cooking section defining member 43. The lower end side of the side wall surface 42 b of the forming member 42 is supported by the upper end edge of the opening of the container body 2. Further, the outer peripheral edge of the top plate 43 a of the cooking section defining member 43 supports the lid 5.

  Steam generated in the steam generation chamber 21 is guided to the cooking sections 4 a, 4 b, and 4 c arranged on the steam generation chamber 21, and the cooking object 6 a placed on the tray 41 and the cooking section definition The cooking objects 6b and 6c placed on the top plates 42a and 43a of the members 42 and 43 are steamed and cooked.

Here, although not particularly shown, one or more steam holes are formed in the tray 41 and the top plates 42a and 43a of the cooking section defining members 42 and 43, and steam generated by boiling the water 7 is generated. Is distributed throughout the container. Further, the lid 5 may be provided with a steam vent for appropriately releasing the steam generated in the container to the outside.
The tray 41, the cooking section defining members 42 and 43, and the lid 5 can be formed using the same material as that of the container body 2 as described above, but the lid 5 can visually check the heating target 6. Thus, it is preferable to form with a highly transparent material.

When the container 1 as described above is used, the cooking object 6a, 6b, 6c is placed on the container body 2 while placing the cooking objects 6a, 6b, 6c on the tray 41 and the top plates 42a, 43a of the cooking partition defining members 42, 43. Water 7 is injected. Then, the induction heating heating element 3 is operated in a state where the induction heating heating element 3 is immersed in water, and the induction heating heating element 3 is caused to generate heat. Then, the water 7 in contact with the induction heating heating element 3 is heated and boiled, and the cooking objects 6a, 6b, 6c can be steamed and cooked by the steam generated in the container.
In addition, the water 7 poured into the container body 2 may contain a flavoring agent, an oil component, a seasoning liquid, and the like as necessary.

  Thus, the container 1 can be used as a steamer by an electromagnetic cooker simply by injecting water 7 during cooking. If different types of ingredients are used as cooking objects 6a, 6b, 6c and individually stored in each of the cooking sections 4a, 4b, 4c, various steamed dishes can be prepared by steaming and cooking them at the same time. It can be provided simply.

In addition, when arrange | positioning a several cooking division on the steam generation chamber 21, the specific definition means of a cooking division is not restrict | limited in particular. For example, as shown in FIG. 10 , the cooking section defining member 44 having a top plate 44 a about half the size of the tray 41 and having a side wall surface 44 b formed along the outer periphery of the tray 41 is placed on the tray 41. The cooking section defining member 44 is covered with the lid 5 together with the tray 41, and the first cooking section 4a partially covered with the cooking section defining member 44 is defined on the tray 41. In addition, the second cooking section 4 b may be formed on the top plate of the cooking section defining member 44.
Incidentally, FIG. 10 (a), similarly to FIG. 1 shows a container longitudinal section at a position corresponding to A-A cross section of FIG. 2 (a), FIG. 10 (b), the lid 5 It is a container top view of the state removed.

By the way, when steam is generated in the container, the water 7 injected into the container body 2 is reduced accordingly. In the present embodiment, in the process in which the water 7 decreases and the induction heating heating element 3 is exposed from the water surface, a fuse function part 3a that is preferentially broken is provided in the induction heating heating element 3, and this It is preferable that when the fuse function unit 3a is broken, the electromagnetic cooking device is stopped by operating the safety mechanism.
FIG. 2B shows a state in which the fuse function portion 3a is broken, and a broken portion is indicated by a symbol C in the drawing.

  By providing such a fuse function unit 3a in the induction heating heating element 3, the amount of water injected into the container body 2 during cooking is arbitrarily adjusted according to the time required for cooking, so that induction heating heat generation is achieved. When a predetermined time elapses after the body 3 is heated, the fuse function part 3a is broken by heat, and the cooking can be automatically ended. Moreover, even if the user forgets to inject the water 7, the fuse function unit 3a is preferentially broken, so that it is possible to prevent emptying.

  Moreover, generally the electromagnetic cooker marketed prevents the high frequency magnetic field by an electromagnetic induction heating coil from heating a table, for example, when the table in which an electromagnetic cooker is installed is metal. Therefore, a high frequency magnetic field is controlled by arranging a ferrite core under the electromagnetic induction heating coil, and the generated high frequency magnetic field has a non-uniform magnetic flux density distribution. For this reason, the part where the magnetic flux density distribution is high and the density of the induced eddy current is high breaks before the fuse function part 3a, and in what direction the container 1 is placed on the electromagnetic cooker. Depending on the placement, the fuse function part 3a provided in the induction heating heating element 3 may not break as intended.

For this reason, in this embodiment, when the induction heating heating element 3 is attached to the container body 2 as in the illustrated example, the induction heating heating element 3 is inclined with respect to the horizontal plane, and the outer edge side is in the vertical direction. It is preferable to provide the fuse function part 3a that preferentially breaks in the inclined part by forming the inclined part located in the upper part in the induction heating heating element 3.
The fuse function part 3a provided in this way is exposed from the water surface before other parts, and at the time when a part or all of the fuse function part 3a is exposed from the water surface, most other parts are exposed. It will be immersed in water. Therefore, even if the magnetic flux density distribution of the high-frequency magnetic field is high in a portion other than the fuse function portion 3a, the heat generated in that portion is taken away by the water 7, so that breakage is avoided. On the other hand, the fuse function part 3a is exposed from the water surface, the heat flow to the water 7 is interrupted, and the fuse function part 3a is preferentially broken preferentially.

Thereby, the fuse function part 3a can be functioned more reliably and stably, and the time management from when the induction heating heating element 3 is heated until the fuse function part 3a breaks can be performed more accurately.
Furthermore, since the induction heating heating element 3 (on the outer edge side of the fuse function portion 3a) is located near the water surface, it is possible to reduce the time when steam starts to be generated, and the induction heating heating element 3 is inclined. If there is a site to do, there is also an advantage that it is easy to escape the bubbles generated when the water 7 boils.

  In the illustrated example, the induction heating heating element 3 has a substantially circular shape, and the length from the outer edge side to the center part is made equal between the fuse function part 3a and other parts. However, if the fuse function part 3a can be broken in preference to other parts, the length from the outer edge side to the center part of the fuse function part 3a is longer than the other parts. May be.

  Here, in the example shown in the figure, the induction heating heating element 3 is inclined as a whole by attaching the induction heating heating element 3 to the container body 2 so that the distance from the inclined bottom surface of the container body 1 is substantially constant. However, as long as the induction heating heating element 3 faces the bottom surface of the container body 2, the distance between the induction heating heating element 3 and the inner bottom surface of the container body 2 may not be constant. Therefore, the induction heating heating element 3 can be inclined and attached to the horizontal bottom surface.

Moreover, if the fuse function part 3a can be broken more preferentially, it is not necessary to incline the entire induction heating heating element 3 with respect to the horizontal plane . That is, the induction heating heating element 3 is attached to the container body 2 so that at least a part of the induction heating heating element 3 is inclined with respect to the horizontal plane, and an inclined portion whose outer edge side is positioned higher in the vertical direction is formed. Therefore, if the fuse function unit 3a functions more reliably and stably, the specific mode of attaching the induction heating heating element 3 is not particularly limited.

  Further, in order to make the fuse function portion 3a easily break from the outer edge portion toward the center portion, a hole or a slit or the like penetrating the induction heating heat generating member 3 is provided at almost the center of the induction heating heat generating member 3. It is preferable to provide the through portion 3c, and in the illustrated example, a circular hole is provided. By providing the penetration part 3c, convection of the water 7 can be promoted between the front surface side and the back surface side of the induction heating heating element 3, but in addition to such a penetration part 3c or the penetration part 3c, Instead, the induction heating heating element 3 may be provided with one or more convection portions 3d penetrating the induction heating heating element 3.

Here, in order for the fuse function part 3a to function stably, it is preferable to suppress the induction heating heating element 3 from shaking vigorously due to bubbles generated when the water 7 boils. For this purpose, the convection of the water 7 is made good, and bubbles generated during boiling are released from the piercing part 3c and the convection part 3d so that the load on the induction heating heating element 3 is reduced. It is also possible to optimize the shape and arrangement of 3c and the convection part 3d.
FIG. 3 shows an example of the arrangement of the penetrating part 3c and the convection part 3d. In this example, the penetrating part 3c provided at the center of the induction heating heating element 3 has a slit shape.

  Furthermore, in the illustrated example, as described above, the induction heating heating element 3 can be attached to the container main body 2 while applying tension, but by doing so, at least the fuse function unit 3a has the structure shown in FIG. In (a), tension acts in the direction indicated by the arrow Ft. By applying such tension to the fuse function portion 3a, the fuse function portion 3a is promoted to break, and the fuse function portion 3a can be more reliably broken with priority.

  Furthermore, in the example shown in the figure, the convex portion 2b provided at the approximate center of the container main body 2 is inserted into the through-hole 3c formed as a circular punch hole so that the central portion of the tray 41 is supported. Providing such a convex portion 2 b is preferable for preventing the tray 41 from drooping and ensuring the strength of the container body 2.

Further, in the present embodiment, for example, the length from the outer edge portion of the induction heating heating element 3 to the central portion is adjusted for each part, and the outer edge portion side of the induction heating heating element 3 is extended to the central portion. It is also possible to carry out a modification so that the length up to is relatively short in the fuse function part 3a. In the example shown in FIG. 4, the induction heating heating element 3 has a rectangular shape, and its four corners are fixed to a support portion 2 d formed to protrude from the bottom surface of the container body 2.
FIG. 4 is a plan view schematically showing a state in which the induction heating heating element 3 is attached to the container body 2 in the present modification.

  In this way, the eddy current density induced in the induction heating heating element 3 is biased, the eddy current density in the fuse function unit 3a is the highest, and the heat generation amount is increased, thereby ensuring more certainty. The fuse function part 3a can be broken with priority over others.

  Here, in FIG. 4A, a circle having a radius from the outer edge portion to the center portion of the induction heating heating element 3 in the fuse function portion 3a is indicated by a two-dot broken line. In the example shown in the drawing, the length of the induction heating heating element 3 is made different in length and width, and the length from the outer edge to the center is made shorter than other parts, but the induction heating heating element 3 An arbitrary part may be cut out, and the length from the outer edge part to the center part may be shorter than other parts.

In this embodiment, the steam generation chamber 21 is modified as in the example shown in FIG. 5 so that a predetermined amount of water 7 weighed in advance is sealed in the container body 2 and the container 1 is in that state. Can be distributed.
In addition, FIG. 5 is explanatory drawing which shows the modification of the steam generation chamber 21 in the induction heating cooking container which concerns on this embodiment, and the container vertical cross section in the position corresponded to the BB cross section of Fig.9 (a) mentioned later. Shows the surface.

  In this modification, when the induction heating heating element 3 is attached to the container body 2, for example, a rectangular induction heating heating element 3 as shown in FIG. 6 is used. The induction heating heating element 3 has four corners as support portions 3e, and the support portion 3e is supported by a step portion 2a formed along the inner periphery of the container body 2.

  In this modification, the step 2a formed on the container body 2 and the outer peripheral edge 41a of the tray 41 supported by the step 2a are fitted to each other, and are provided on the step 2a. The fitting recess 2e and the fitting projection 41b provided on the outer peripheral edge 41a of the tray 41 are fitted. When the outer peripheral edge portion 41a of the tray 41 is fitted to the step portion 2a, the support portion 3e of the induction heating heating element 3 is sandwiched between the step portion 2a and the outer peripheral edge portion 41a of the tray 41. It is like that.

In addition, a plurality of holding pieces 3g are formed at substantially the center of the induction heating heating element 3 by providing the cuts 3f radially. On the other hand, a convex portion 2b having a distal end portion that can be bent and deformed is provided substantially at the center of the container body 2.
And the convex part 2b formed in the container main body 2 is inserted in the center part in which the notch 3f of the induction heating heating element 3 is formed radially, and in that state, the base part side surface of the convex part 2b is covered. The holding piece 3g formed at the center of the induction heating element 3 is bitten and held while the tip of the convex portion 2b is bent and deformed downward (FIGS. 8B and 8C). reference).

  That is, FIG. 8 is an explanatory view showing a procedure for attaching the induction heating heating element 3 and the like to the container body. As shown in the figure, when the convex portion 2b is pushed down from above, a constriction at the center in the height direction is provided. The tip part is deformed so that the base side of the convex part 2b enters into the tip part and covers the side surface of the base part side of the convex part 2b. At this time, the induction heating heating element 3 The holding piece 3g is bitten.

  In addition, as described above, from the cooking section disposed at the upper level, the liquid component (smell component) that has been oozed out by steaming the contained food is steamed through the steam hole, and the cooking is disposed immediately below it. It can be dripped into the compartment. For this reason, as a foodstuff suitable for accommodating in the cooking division arrange | positioned at the upper rank, the foodstuff characterized by flavor like a seafood etc., the foodstuff with much water content, etc. can be illustrated, for example.

  On the other hand, examples of suitable foods to be stored in the cooking section arranged at the lower level include crispy foods such as noodles and fried foods, and foods for removing excess fat such as meat. It is preferable that the liquid component (umami component) oozing out from the food contained in the cooking section arranged at the upper level is dropped and seasoned or flavored.

  By individually storing these ingredients in the upper and lower cooking sections, the ingredients were stored in the upper cooking section while maintaining the texture and texture of the ingredients stored in the lower cooking section. Since the liquid component that has oozed out after the food is sufficiently heated is dropped onto the food stored in the cooking section arranged at the lower level, full-scale cooking can be reproduced.

  Further, in the present embodiment, not only the liquid component that has oozed out of the food material, but also the food material melted and softened by heating may fall into the cooking section disposed below. Examples of such foods include foods that are fluidized by heating, such as melted cheese, sauce, and sauce hardened with gelatin.

  Further, in the present embodiment, the steam holes formed in the tray-like top plates 42a and 43a of the cooking section defining members 42 and 43 are closed with the thermoplastic resin having a melting point of 100 ° C. or lower as described above. You can also. If it does in this way, the timing at which the foodstuff accommodated in the cooking divisions 4b and 4c arrange | positioned in the upper level is steamed, the timing at which the liquid component which exuded from the steamed foodstuff is dripped, Furthermore, foodstuff It is possible to control the timing of the softening and falling. In addition, by closing the steam hole, it is possible to store a fluid food material in the cooking section disposed above the steam hole even in a state before heating, and such a food material has an appropriate timing. And it can also be made to be dripped at a lower cooking division.

  Furthermore, in this embodiment, while adjusting the size of the steam holes or making dedicated drop holes and closing them with a thermoplastic resin having a melting point of 100 ° C. or less, for example, lower cooking Cooking with soup in the compartment, croutons in the upper cooking compartment, and when cooking is advanced to some extent so that the croutons fall into the soup during cooking It can also be dropped into the compartment.

Below, the preferable combination of the foodstuff accommodated in the cooking division located in the upper rank and the foodstuff accommodated in the cooking division located in the lower rank is illustrated.
