In the figure, reference numeral 1 denotes a microwave oven that is made by combining paper as a main material and a heating sheet for cooking by heating in a microwave oven, which will be described later. The microwave heating apparatus 1 includes a heating unit 5 including two sandwiching plates 3 and 4 that are connected to each other through a first folding unit 2 and folded in a spreadable manner so as to have substantially the same shape. The heating unit 5 is formed of a base plate 7 connected to a side opposite to the first folding unit 2 in one clamping plate 4 via a second folding unit 6 and is curved as described later. , And a base portion 8 which becomes a flat bottom in the microwave heating apparatus 1.

  As shown in the developed view of the microwave heating apparatus 1, the two sandwiching plates 3, 4 and the base plate 7 are connected via the first folding portion 2 and the second folding portion 6. Further, a tab 10 is connected to the side of the base plate 7 opposite to the holding plate 4 via a third fold 9. An instrument main body 11 in which the clamping plate 3, the clamping plate 4, the base plate 7, and the knob 10 are connected in series is obtained by punching a paper material. The sandwiching plate 3 is folded on the sandwiching plate 4, and the folded sandwiching plates 3 and 4 are folded together and folded in the same folding direction from the second folding portion 6 to the base plate 7 side. ing. In this way, the holding plate 3 opposite to the side where the base plate 7 of the heating unit 5 is connected is started to be folded, and the heating plate 5 is folded from the holding plate 3 so as to be folded. It is made to overlap with the upper surface side of the base plate 7 which is a terminal end, and the base portion 8 constituted by the base plate 7 serves as a flat bottom to support the heating portion 5. Further, as described later, the first folding portion 2 is placed on the table so that the two sandwiching plates 3 and 4 are in a curved state, that is, the heating portion 5 is maintained in a curved state. The shape that can be locked to the portion 8 is formed by folding.

  Of the facing surfaces 3a and 4a of the sandwiching plate 3 and the sandwiching plate 4 that are folded over by the heating unit 5 and facing each other, the facing surface of the sandwiching plate 4 that is located on the uppermost side in the microwave heating device 1 4a, a heating sheet 12 for cooking by heating with a microwave oven having a size smaller than that of the sandwiching plate 4 is disposed, and the heating unit 5 positions a sheet-like food 13 such as dry seaweed between the sandwiching plates 3 and 4, The microwave-heated cooking sheet 12 is heated by being irradiated with microwaves while the sheet-like food 13 is in contact with the microwave-heated heating sheet 12 and sandwiched between the sandwiching plates 3 and 4. I try to do it. The sandwiching plate 4 is provided with arc-shaped slits 14 at positions corresponding to the opposing side portions of the heating sheet 12 for cooking by heating the microwave oven, and each of the slits 14 is heated by the microwave oven. The side of the cooking heat generating sheet 12 is inserted, and the heat generating sheet 12 for microwave thermosensitive cooking is detachably attached. In addition, attachment of the heat generating sheet 12 for microwave heating cooking is not limited to this example.

  Place the sheet food such as dry seaweed on the heating sheet 12 for cooking by heating in the microwave oven, and place it on the sandwiching plate 3 on the opposite side of the first folding part 2. A convex portion 15 is provided that protrudes outward (a direction along the connecting direction of the sandwiching plates 3 and 4). Further, the second folding part 6 between the sandwiching plate 4 and the above-described base plate 7 on which the sandwiching plate 3 is folded is placed between the pair of creases 16 as shown in the figure. It is made continuous by a notch 17 that is convex toward the side, and has a notch shape that is located on the base plate 7 side from the extended line of the crease 16.

  And the said convex part 15 of the clamping board 3 overlaid so that the heat generating sheet 12 for microwave oven cooking and the sheet-like food 13 may be covered, as shown in FIG. It is provided so as not to overlap the notch 17 while correspondingly located on the extension. That is, the convex portion 15 corresponds to the convex portion 18 formed by projecting from the sandwiching plate 4 to the base plate 7 side by the notch 17, and the heating unit 5 is folded to the base portion 8 side as shown in FIG. Thus, the projection 15 is provided in the opening 19 formed by the projection 18 projecting outward, so that the mutual displacement between the clamping plate 3 and the clamping plate 4 does not increase. Further, since the opening 19 is formed, the water vapor generated from the sheet-like food 13 heated by the heating unit 5 is not only the upper and lower gaps (between the upper and lower sides of the sandwiching plates 3 and 4) of the heating unit 5. In addition, it can be discharged from the opening 19.

  The base plate 7 of the base portion 8 composed of the base plate 7 and the knob 10 has a width dimension in a direction orthogonal to the folding portions 2 and 6 smaller than a width dimension of the heating portion 5 in the same direction. It has been. And the base part 8 has the shape holding means 20 which maintains the heating part 5 in the curved state which becomes circular arc shape in the cross section in the direction orthogonal to the folding parts 2 and 6, and this shape holding means 20 As described above, it is located in the third folding part 9 between the base plate 7 and the knob 10 having a width smaller than the width of the heating part 5.

  As shown in FIG. 2, the third fold portion 9 is formed by connecting the crease 21 divided into three parts with a notch 22 that is convex toward the knob 10 side. As the cut shape located on the knob 10 side from the extension line 21, the knob 10 is folded from the position of the third fold 9 with respect to the base plate 7, thereby forming an opening at the position of the cut 22. Shape holding means 20 is formed.

  In the base part 8, the width dimension of the base plate 7 is provided smaller than the width dimension of the heating part 5, and the shape holding means 20 is provided between the base plate 7 and the knob 10 and is folded down to the base part 8 side. By holding the part of the first folding part 2 of the heating part 5 by the shape holding means 20, the heating part 5 is in a curved state with an arcuate cross section. As shown in FIG. 2, the heating unit 5 is fastened to the shape holding unit 20 by engaging the convex portion 23 formed by cutting at a position corresponding to the shape holding unit 20 in the first folding unit 2. The heating unit 5 is held in a curved state by the detachable locking of the convex portion 23 to the shape holding means 20 shown in FIG. The difference between the width dimension of the base plate 7 and the width dimension of the heating unit 5 is preferably not less than 1 cm when the width dimension of the heating unit 5 is 15 cm, for example. Of course, it is desirable to make it the range which does not impair the flexibility of each clamping board.

  The formation of the convex portion 23 in the first fold portion 2 is the same as that of the second fold portion 6 and the third fold portion 9 described above. The first folding part 2 is formed in a shape connected by a notch 25 having a convex shape on the 3 side, and the convex part 23 is formed at the part of the notch 25 when the first folding part 2 becomes the folding position. Is done. Of course, the locking method to the shape holding means 20 is not limited to this example.

The material which forms the said apparatus main body 11 of the microwave oven 1 should just have the heat resistance which has flexibility and can fully endure the heat_generation | fever of the said heating sheet for microwave heating cooking. If it is a normal paper material used as a general packaging material, it has sufficient flexibility and heat resistance enough to withstand even if it is in contact with a heat-generating sheet for heating by a microwave oven. Therefore, as described above, it is preferable to select a paper material as the material of the appliance main body 11, and if it is a paper material, the appliance main body 11 can be easily folded. The sandwiching operation is also easy. And it can satisfy | fill the conditions which the clamping plates 3 and 4 of the heating part 5 have flexibility and also have heat resistance. As a specific material, card paper “Pearl Card” (350 g / m ² ) manufactured by Mitsubishi Paper Industries Co., Ltd. can be used.

The heating sheet 12 for cooking by heating in the microwave oven shown in the above example is an embossed conductive paper 27 (craft paper, Oji Paper Co., Ltd. “Whale” (100 g / m ² )). ). As the heat generating film 26, a metal vapor deposition such as aluminum vapor deposition is performed on the lower surface (embossed paper side) of the heat resistant film and covered with a protective paper, and when the metal vapor deposition layer is irradiated with microwaves from a microwave oven. It is a layer that generates heat. (Fig. 6)

  As described above, the heating sheet 12 for cooking by heating in the microwave oven includes the embossed paper 27 that has been embossed, and the embossed paper 27 serves as a cushion layer. As described above, the heating sheet 12 for cooking by heating in a microwave oven has a cushion layer on the lower side (on the sandwiching plate 4 side) of the heating portion to be a layer. When sandwiched between the heating parts 5 in a state of being opposed to each other, the embossed paper 27 corresponding to the curved bent part in the thickness direction of the sheet-like food 13 is deformed by being thinned or crushed, and generates heat. The film 26 is provided so as to be in contact with the surface shape of the sheet-like food 13. Therefore, the heating from the heating sheet 12 for microwave cooking can be appropriately applied to the sheet-like food. As an alternative to providing cushioning to the microwave oven cooking sheet 12, the sandwich plate side on which the microwave oven cooking sheet is placed is embossed to elastically heat the microwave heating sheet. It is also possible to make it contact the food product side.

  In addition, since the heating unit 5 itself has a curved shape with a circular arc cross section, the shape does not change even if the heating sheet 12 for microwave heating cooking is heated. Therefore, the sheet-like food is also baked while the deformation due to heating is suppressed and the sheet-like shape is maintained.

  FIG. 7 is a device that makes it easy to take out the microwave heating device 1 heated by microwave irradiation from the inside of the microwave oven, and is cut and raised from the base plate 7 to be positioned on the center line of the microwave heating device. In addition, a pair of knobs 28 projecting outward in the same direction as the direction along the third folding portion 9 of the base portion 8 and opposite to each other are provided. Thus, since the knob piece 28 cut and raised from the side of the base portion 8 is formed in two pieces and protrudes in the opposite direction, the heating that is heated under the influence of the heat generation of the heating sheet for microwave heating cooking is heated. Without touching the part 5, the two pieces 28 can be picked and easily taken out of the microwave oven.

  Similarly, FIG. 7 shows a device for easily discharging water vapor generated from the sheet-like food 13 between the sandwiching plate 3 and the sandwiching plate 4 when the sheet-like food 13 is sandwiched in the heating unit 5 and cooked in a microwave oven. In the heating unit 5, a substantially I-shaped slit 29 is provided in the sandwiching plate 4, which is a plate material on the upper side in the heating unit 5, so that the notch edges are opened by the curvature of the sandwiching plate 4. . If it does in this way, the water vapor | steam which arises from a sheet-like foodstuff at the time of microwave irradiation will be discharge | released outside from the slit 29, and will not remain in a heating part, and it can make it easier to keep the baking state of a sheet-like foodstuff better.

  In the above embodiment, the heating sheet for cooking by heating the microwave oven is positioned on the opposing surface of one of the sandwich plates. However, the heating sheet for heating cooking by the microwave oven is arranged on both opposing surfaces, so that the sheet-like food is disposed. May be heated from both sides.

  In the embodiment shown in FIGS. 1 to 7, the heating unit 5 is shown in a form in which the two sandwiching plates 3 and 4 are connected via the first folding unit 2. The heating unit 5 is not limited to a form in which two sandwiching plates are connected, and three or more sandwiching plates may be connected.
