The bottom 21 of the steam generation container 20 can have an arbitrary shape such as a circular shape, a square shape, a rectangular shape, or another polygonal shape. If the induction heating heating element 30 is immersed in the accommodated water 50 when the water 50 is accommodated in the steam generation container 20, a specific form of the steam generation container 20 or the induction heating heating element The attachment means of 30 is not specifically limited.

  Moreover, since the cooking-by-heating container 1 is generally used on a commercially available electromagnetic cooking device, the size of the steam generating container 20 depends on the size of the heating coil provided in the electromagnetic cooking device to be used. Can be set. For example, a general heating coil included in a commercially available home-use electromagnetic cooker has an inner diameter of about 5 cm and an outer diameter of about 20 cm. The size is appropriately determined according to the cooking device.

  On the opening side of the steam generation container 20, a step portion 23 is provided along the entire circumference of the inner peripheral edge of the side wall portion 22. A tray 25 having a large number of steam holes 25 a is supported by the stepped portion 23 so as to cover the opening of the steam generating container 20. As a result, when the induction heating heating element 30 is heated while being immersed in the water 50 accommodated in the steam generation container 20 and the water 50 is boiled, the steam generated by the boiling of the water 50 is drilled in the tray 25. The steam holes 25a are ejected.

In addition, the heating and cooking container 1 includes a plurality of individual containers 40 that can accommodate various foods to be cooked in small portions. The individual container 40 has a container body 41 and a lid body 42, and a steam hole 41 a is formed in the bottom surface of the container body 41, and a steam hole 42 a is formed in the top surface of the lid body 42. Yes. The individual containers 40 are arranged side by side on the tray 25 as shown in the figure, and can be arranged even when stacked one above the other.
In addition, in FIG. 1, illustration of the cooking object accommodated in the separate container 40 is abbreviate | omitted.

  Here, the specific form of the individual container 40 is not limited to the illustrated example. Depending on the cooking object to be accommodated, or considering the convenience and design, the bottom surface of the container body 41 is optional, such as a circular shape, a fan shape, a triangular shape, a square shape, a rectangular shape, or another polygonal shape. It can be made into the shape. Furthermore, it is possible to mix and use individual containers 40 of different heights without making all the individual containers 40 the same height, for example, as a combination of two individual containers 40, Individual containers 40 having different sizes can also be used in a mixed manner.

The steam hole 41a drilled in the bottom surface of the container body 41 of the individual container 40 is a steam hole 25a drilled in the tray 25 so that the steam ejected from the steam hole 25a of the tray 25 is introduced into the individual container 40. Are drilled in the same arrangement pattern.
That is, when arranging the individual containers 40 side by side on the tray 25, the position on the tray 25 where the individual containers 40 are arranged is determined, the steam holes 25a drilled at the positions, and the positions. The position where the individual container 40 is disposed on the tray and the steam hole 25a formed in the tray 25 so that the steam hole 41a formed in the bottom surface of the container body 41 of the individual container 40 is in communication. And the arrangement pattern of the steam holes 41a formed in the bottom surface of the container body 41 of the individual container 40 are set in association with each other.
By doing in this way, the steam spouted from the steam hole 25a drilled in the tray 25 is introduced into the individual container 40, and the cooking object accommodated in the individual container 40 is steamed by the steam so that cooking can be performed. It is.

Further, in the illustrated example, the vapor holes 41a formed in the bottom of the container body 41 of the individual container 40 and the vapor holes 42a formed in the top surface of the lid body 42 are formed in the same arrangement pattern. is doing. When the individual containers 40 are stacked one above the other, the vapor holes 42a drilled in the top surface of the lid 42 of the individual container 40 positioned below, and the container body 41 of the individual container 40 positioned above. The vapor hole 41a drilled in the bottom surface of the slab communicates with the steam hole 41a.
By doing in this way, after the vapor | steam introduce | transduced in the individual container 40 located below is filled in the said individual container 40, it was guide | induced to the individual container 40 located above, and was piled up and down The cooking object accommodated in each individual container 40 can be steamed simultaneously.

In arranging the individual container 40 on the tray 25, positioning means can be provided.
Here, FIGS. 2 to 5 are explanatory diagrams more specifically showing the induction heating cooking container according to the present embodiment, and FIG. 2 is a plan view showing a state in which four individual containers 40 are arranged on the tray 25. 3 is a plan view showing a state where the individual container 40 is removed from the state shown in FIG. 2, and FIG. 4 is a plan view showing a state where the tray 25 is removed from the state shown in FIG. . FIG. 5 is a cross-sectional view taken along the line AA in FIG.

In the example shown in these drawings, a total of four individual containers 40 are arranged side by side on the tray 25, two vertically and two horizontally. As shown in FIGS. 3 and 5, at the positions on the tray 25 where the individual containers 40 are arranged, the inclined portions 60a and the step portions 61a are arranged radially at equal pitches along the circumferential direction. An uneven shape is formed. On the other hand, the bottom surface of the container body 41 of the individual container 40 is formed with the same uneven shape that engages with the uneven shape formed on the tray 25 side, and by engaging these uneven shapes, the individual container 40 positioning is performed.
Further, as shown in FIGS. 2 and 5, the same uneven shape as the uneven shape formed on the tray 25 is also formed on the top surface of the lid 42 of the individual container 40 by the inclined portion 60b and the step portion 61b. In addition, when the individual containers 40 are stacked one above the other, positioning is performed by engaging the concave and convex shapes of each other.

By providing such positioning means, when the individual container 40 is arranged on the tray 25, the steam hole 25a on the tray 25 side and the steam hole 41a on the individual container 40 side can be easily aligned. In addition, when the individual containers 40 are stacked one above the other, it is easy to align the vapor holes 42a on the individual container 40 side located on the lower side and the vapor holes 41a on the individual container 40 side located on the upper side.
Further, since the concavo-convex shapes are engaged with each other, it is possible to prevent the individual container 40 from being displaced from the tray 25 when transported while the individual container 40 is disposed on the tray 25. In order to effectively prevent such a deviation drop from the tray 25 of the individual container 40, the ridge line formed by the intersection of the inclined portion and the stepped portion is preferably a curved shape as illustrated, Even so, the displacement of the individual container 40 can be sufficiently prevented.

Further, in the illustrated example, when the positioning means as described above is provided on the tray 25 and the lid 42 of the individual container 40, the concave portion 62a is formed at the center of the concave and convex shape including the inclined portions 60a and 60b and the step portions 61a and 61b. 62b, and inclined portions 60a, 60b and stepped portions 61a, 61b are formed so as to protrude around the recessed portions 62a, 62b. The steam holes 25a and 42a are formed at predetermined positions of the inclined portions 60a and 60b every other along the circumferential direction, and are also formed in the recessed portions 62a and 62b (FIG. 2). And FIG. 3).
On the other hand, a similar concave portion is provided on the bottom surface of the container main body 41 of the individual container 40 by denting the center inward of the container. The inclined portion and the stepped portion are formed so as to be relatively raised around the recessed portion, and the vapor holes 41a are formed in the same arrangement pattern as the vapor holes 25a and 42a.

By doing in this way, the vapor | steam which ejects from the vapor hole 25a formed in the recessed part 62a of the tray 25 always becomes the individual container 40 from the vapor hole 41a provided in the recessed part 62b of the bottom face of the container main body 41 of the individual container 40. When the individual container 40 is rotated by shifting by one pitch (that is, one inclined part) along the circumferential direction, the vapor holes provided in the inclined part are closed to each other, and the individual container 40 is introduced. The amount of steam introduced into the interior can be adjusted.
Note that the amount of steam introduced from the individual container 40 positioned below to the individual container 40 positioned above can be adjusted in the same manner between the individual containers 40 stacked one above the other. Further, when the individual container 40 is disposed on the tray 25 or when the individual containers 40 are stacked one above the other, the recessed portions 62a and 62b provided on the tray 25 side or the lid body 42 side of the individual container 40, and the individual containers A constant gap is formed between the 40 recesses provided on the container body 41 side. For this reason, even if there is a deviation in the arrangement pattern of the steam holes drilled in these recesses, it does not hinder the introduction of steam into the individual container 40.

  When using the cooking container 1 as described above, the ingredients to be cooked are accommodated in individual containers 40 and the individual containers 40 are arranged at predetermined positions on the tray 25. Depending on the number of the individual containers 40, the individual containers 40 can be arranged side by side on the tray 25 and then stacked one above the other. However, the heating of the cooking object accommodated in the individual container 40 is required. Depending on the degree, the vertical positional relationship can be adjusted as appropriate.

Next, the electromagnetic cooker is operated in a state where the induction heating heating element 30 is immersed in the water 50 accommodated in the steam generating container 20, and the induction heating heating element 30 is caused to generate heat, whereby the water 50 is heated and boiled. Then, the steam generated with the boiling of the water 50 is ejected from the steam hole 25 a formed in the tray 25 and introduced into the individual container 40 arranged on the tray 25. Thereby, the cooking object accommodated in each individual container 40 is steamed with steam, and various steamed dishes can be provided simply.
At this time, when the individual containers 40 are also stacked on the upper and lower sides, after the vapor introduced into the individual container 40 located below fills the individual container 40, the individual container 40 located on the upper side. It is possible to steam the objects to be cooked that are guided in and housed in the individual containers 40 stacked vertically.

The induction cooking container according to the present invention can easily provide steamed dishes as described above. As a more specific distribution form in the market, for example, the following can be considered.
In other words, foods that can be cooked only by steaming, such as cooked prepared foods, semi-cooked products such as raw fish and raw shumai, sweets such as buns, and cooked cold and cooked rice Are stored in individual containers 40 and sold in stores.
And those who have purchased these can simply take steamed dishes with an electromagnetic cooker by simply taking them home or placing the purchased individual containers 40 on the tray 25 of the steam generation container 20 separately prepared in the store. Can be cooked to.

Thus, the induction heating cooking container which concerns on this invention is marketed as a cooking set which can taste various steamed dishes easily with an electromagnetic cooker by accommodating various cooking objects in the individual container 40. It can also be distributed.
And since it distributes to the market as such a cooking set, the object to be cooked is accommodated in the individual containers 40, so there is no concern that the ingredients are biased during transportation unlike conventional commercially available lunch boxes. Further, the purchaser can select foods in various combinations according to his / her preference, and the degree of freedom of selection is remarkably high.
In addition, in this invention, since the cooking object is accommodated in the individual container 40 in small portions, even in a situation where the electromagnetic cooker cannot be used, the purchaser separates the individual container 40 and uses, for example, a microwave oven. It is also possible to cook the object to be cooked using alternative means such as heating.

[Second Embodiment]

However, in this embodiment, the hot water bath container 45 is held on the tray 25 together with the individual container 40, so It can be used for bathing liquids such as sauces, roux, and sake.

  For this reason, in this embodiment, a part of the tray 25 is depressed to form a receiving hole 26, and the receiving hole 26 is used as a hot water bath holding part. A water passage hole 27 as shown in the drawing is provided on the side surface of the receiving hole 26 so that the water level of the water 50 is the same between the inside and the outside of the receiving hole 26.

Such a receiving hole 26 can also be used as a water inlet for water 50. For this reason, as shown in FIG. 7, it is preferable to provide a water level line 51 on the inner surface of the receiving hole 26 with a marking line or the like. By providing the water level line 51, the work of pouring the required amount of water 50 becomes easy.
If the receiving hole 26 is a water inlet, it is not necessary to remove the tray 25 when water 50 is poured. For this reason, by fixing the tray 25 to the steam generation container 20, the induction heating heating element 30 can be made difficult to touch the eyes of the user.

  Further, the hot water bath container holding portion may be an insertion hole 28 as shown in FIG. In this case, a step 45a as illustrated is formed in the hot water bath 45. As a result, the stepped portion 45a is supported by the peripheral portion of the insertion hole 28, and the steam bath 45 can be held on the tray 25 while preventing vapor leakage from the insertion hole 28.

  In forming the hot water bath holding portion as described above on the tray 25, positioning means having the uneven shape as described above may be provided around the receiving hole 26 and the insertion hole 28. By doing in this way, the individual container 40 can be arrange | positioned instead of the water bath container 45. FIG.

  As mentioned above, although the preferable embodiment was shown and demonstrated about the induction heating cooking container which concerns on this invention, this invention is not limited only to above-described embodiment, A various change implementation is possible in the scope of the present invention. Needless to say.

  For example, the induction heating heating element 30 is formed with a portion that selectively generates excessive heat, so that the level of the boiling water 50 is lowered and the induction heating heating element 30 is exposed on the water surface. Sometimes the site can be broken in preference to other sites. By doing so, the induction heating heating element 30 breaks, and the safety mechanism operates to stop the electromagnetic cooker. Therefore, the heating of the object to be heated is automatically terminated after a predetermined time without depending on the operation of the device. It becomes possible to make it.

  As described above, the present invention can be used as a packaging container for foods such as frozen or refrigerated food, and can be easily used as a steamer with a commercially available electromagnetic cooker, and its The cooking set which accommodates a foodstuff in such an induction heating cooking container is provided.
