Description

  The present invention relates to an electromagnetic cooker in which food lines are heated and cooked by bringing a magnetic field line generation surface into contact with or close to an upper surface and a lower surface of a metal heating container containing food and heating the heating container up and down simultaneously.

  In a conventional electromagnetic cooker, the magnetic lines generated from the surface of the magnetic lines generate eddy currents on the bottom surface of the heating container made of a metal container, and the eddy currents generate Joule heat by the resistance of the metal, and the heating It is a cooking utensil that heats the bottom of the container. Since the magnetic field lines generated by the magnetic field generating surface are limited to the range extending to the bottom surface of the heating container, the heating container for the electromagnetic cooker only needs to have a metal layer on the bottom surface, and the electromagnetic cooker mainly heats the bottom surface. And heat the food from below. However, depending on the food, heating up and down simultaneously can finish cooking in a short time and is often preferable. Examples of such foods include okonomiyaki.

  Patent document 1 is disclosing the electromagnetic cooker which has arrange | positioned up and down the magnetic force line generation | occurrence | production surface which attached the to-be-heated body (patent document 1 claim etc.). The object to be heated may be “a material that allows magnetic flux to pass through, such as a metal material”, and is probably an iron plate since the exemplified food is okonomiyaki (see Patent Document 1 [0013] and FIG. 3). ). The upper magnetic force line generation surface is configured to be retracted upward by rotating or moving up and down so that food is sandwiched between the heated objects on the upper and lower magnetic force line generation surfaces. The reason for attaching the heated object to the magnetic field generation surface in advance is that multiple okonomiyaki are baked at a time, so use a large iron plate that can sandwich multiple okonomiyaki simultaneously by preparing a heating container for each okonomiyaki Is considered to be preferable.

Japanese Patent Laid-Open No. 2004-047359

  Since the to-be-heated body used as a heating source is previously mounted | worn with the magnetic force line generation | occurrence | production surface, the electromagnetic cooker of patent document 1 needs the foodstuff to contact | adhere to the to-be-heated body. From this, the cooking that can be performed by the electromagnetic cooker of Patent Document 1 is considered to be only baking cooking that is in close contact with the object to be heated, and boiled cooking that requires a heating container is difficult or unsuitable. In this respect, it is clear from Patent Document 1 that no mention is made of boiled food cooking. This means that the electromagnetic cooker of Patent Document 1 can be used only for specific cooking.

  Certainly, since it is necessary to burn the top and bottom of the food for baking, it is most likely to use the electromagnetic cooker of Patent Document 1 that can be heated simultaneously at the top and bottom. It can be said that it is sufficient to increase the amount of magnetic lines of force in order to generate more Joule heat in an electromagnetic cooker commonly used in the past. However, in order to secure the necessary amount of heat, using multiple heat sources is reasonable in that the performance of each heat source can be kept low, and heat is confined to food by heating up and down simultaneously. Brings the advantage of finishing cooking in a short time.

  An electromagnetic cooker is a cooking utensil that uses Joule heat generated by eddy currents generated in the range where magnetic field lines reach by bringing the bottom surface of a metal surface heating container into contact with or close to the magnetic field line generation surface and cooperates with the heating container. Therefore, it is considered to be a cooking utensil that performs better. Therefore, in order to develop an electromagnetic cooker that cooks food by heating the heating container up and down at the same time, bringing the magnetic field lines generation surface into contact with or close to the upper and lower surfaces of a metal heating container containing food. .

  What has been developed as a result of the study, in the electromagnetic cooker that heats and cooks the food by simultaneously heating the heating container containing the food, the flat bottom magnetic field generating surface attached to the surface of the mounting base, An electromagnetic cooker comprising a combination of a flat upper magnetic field line generating surface attached to the lower surface of a movable base that can be moved up and down along a support column erected on a mounting base, a lid having a metal surface, and a heating container made of a container The lid of the heating container has an upper surface including a flat metal layer that is in contact with or close to the upper surface of the magnetic force lines, and the container of the heating container is flat metal that is in contact with or close to the lower surface of the magnetic force lines. It has a bottom surface including a layer. Here, “an upper surface including a flat metal layer” or “a bottom surface including a flat metal layer” means that the lid and the container are made of metal or enamel.

  The electromagnetic cooker of the present invention comprises a heating container composed of a cover body and a container, which are separate bodies to be heated, from the upper magnetic force line generation surface and the lower magnetic force line generation surface, and the heating container and the upper magnetic force line generation surface, The combination with the lower magnetic field generating surface enables most cooking including baking and cooking. For this reason, the heating container of the present invention includes a flat metal layer in which the bottom surface of the container is in contact with or close to the lower magnetic field radiation surface, and the upper surface of the lid is in contact with or close to the upper magnetic force radiation surface. The structure includes a flat metal surface layer. Although this heating container is a structure suitable for the electromagnetic cooker of this invention, it can be used also for a gas stove etc. like a conventionally well-known heating container.

  If the movable base moves up and down along the support column, the upper magnetic field radiation surface and the lower magnetic field radiation surface are separated from each other, so that the heating container can be taken in and out between them. However, in order to facilitate the easy heating and unloading, it is desirable that the movable base can be moved up and down along the support column and can be rotated up and down with respect to the mounting base. As a result, the elevation of the movable base can be specialized to adjust the height of the upper magnetic field radiation surface according to the height of the heating container. If the specifications of the heating container to be used are constant, the height of the movable base And the movable base only needs to be moved up and down only when the heating container is taken in and out.

  In the electromagnetic cooker of the present invention that enables cooking of boiled food, boiled juice or the like spills from the heating container, and the upper magnetic field generation surface or the lower magnetic field generation surface may become dirty or may break down in some cases. Therefore, it is preferable that the lower magnetic force line generating surface is detachable from the mounting base, and the upper magnetic force line generating surface is detachable from the movable base. Since the performance (especially the amount of heat) of an electromagnetic cooker depends on the performance of the upper magnetic field generation surface or the lower magnetic field generation surface, the upper magnetic field generation surface or the lower magnetic field generation surface that can be freely attached and detached is There is an advantage that it is possible to exchange a new upper magnetic field line generation surface or a lower magnetic field line generation surface.

  In the present invention, the upper surface of the magnetic field generating line is brought into contact with or close to the upper surface of the lid of the heating container containing the food, and at the same time, the lower surface of magnetic force generating is brought into contact with or close to the bottom of the container of the heating container. An electromagnetic cooker that can be used for most cooking including baking and cooking. In the electromagnetic cooker according to the present invention, the lid and container of the heating container are separated from the upper magnetic force line generating surface and the lower magnetic force line generating surface, and the upper magnetic force line generating surface or the lower magnetic force line generating surface is placed on the base. Alternatively, if the movable base is made detachable, the combination of the lid, the container, the upper magnetic force line generating surface or the lower magnetic force line generating surface can be changed. The Joule heat generated in the heating container is the material or thickness of the lid or container, and the area of the metal surface that is in contact with or close to the upper magnetic force line generation surface or the lower magnetic force line generation surface. It varies depending on the amount or strength of the magnetic field lines created by the lower magnetic field line generation surface. From now on, not only the upper magnetic field generation surface or the lower magnetic field generation surface is electrically controlled, but also by changing the combination of the lid, the container, the upper magnetic field generation surface or the lower magnetic field generation surface. Or there is an advantage which can adjust the calorie | heat amount as an electromagnetic cooker, such as cooking.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of an electromagnetic cooker 1 according to the present invention, FIG. 2 is a perspective view corresponding to FIG. 1 of the electromagnetic cooker 1 showing attachment / detachment of an electromagnetic cooking unit 14, and FIG. FIG. 4 is a partially cutaway side view of the electromagnetic cooker 1 showing the turning up and down of the movable base 13. In each figure, illustration of the power supply unit, the control unit, the cords connecting these with the respective electromagnetic cooking units 14 and the power supply cord for the entire apparatus, which are not directly related to the description of the present invention, is omitted, and the necessary limits for each unit are omitted. I will just explain it.

  As shown in FIGS. 1 to 4, the electromagnetic cooker 1 of the present example includes a flat plate-shaped mounting base 11 having a thickness, a gate-type column 12 erected on the mounting base 11, and the gate-type The main body is composed of a movable base 13 having a unit holding part 131 that can be moved up and down with respect to the support column 12, and the same electromagnetic cooking unit 14 is turned upside down with respect to the mounting base 11 and the unit holding part 131. Are attached (see FIG. 2) and used in combination with a dedicated heating container 15 described later. The electromagnetic cooker 1 of the present invention enjoys the effect of finishing cooking in a short time by combining with the dedicated heating container 15. However, if the specifications are such that the two electromagnetic cooking units 14 are individually operated, for example, only the electromagnetic cooking unit 14 attached to the mounting base 11 is operated in a state where the unit holding part 131 is flipped up, It can also be used like an electromagnetic cooker.

  The mounting base 11 has a front surface, a side surface, and a rear surface that are slightly higher than the electromagnetic cooking unit 14, and a front surface and a bottom surface that are substantially rectangular in shape, which are larger than the electromagnetic cooking unit 14, and is provided with an operation unit 111 on the front surface that is a downwardly inclined surface. A power supply unit, a control unit, etc. (not shown) are housed inside, a fitting recess 112 for fitting the electromagnetic cooking unit 14 is provided on the surface, and a portal column 12 is provided at the left and right rear corners along the back surface. It is a configuration. The bottom surface of the mounting base 11 is provided with rubber feet 113 at the four corners so that the entire electromagnetic cooker 1 is not displaced even when the unit holding part 131 is turned up and down. Thus, the mounting base 11 is a base of the electromagnetic cooking device 1 and is not limited to the configuration of this example as long as the configuration does not shift during use.

  The fitting recess 112 is a substantially square recess having the same planar shape as the electromagnetic cooking unit 14, and the main body side power interface 1121 and the main body side control interface for the electromagnetic cooking unit 14 on the inner peripheral back side (right side in FIG. 1). 1122 is provided (see FIG. 2), and a part of the upper edge on the front side of the inner peripheral surface (left side in FIG. 1) is chamfered to form a cutout portion 1123 that assists in attaching and detaching the electromagnetic cooking unit 14. The electromagnetic cooking unit 14 is inserted obliquely from above into the fitting recess 112, and the front portion is pushed down with the back surface pressed against the inner peripheral surface of the fitting recess 112. The unit-side power interface 142 and the unit-side control interface 143 (see FIG. 8) provided on the back surface portion are fitted into the fitting recess 112 while being connected to the body-side power interface 1121 and the body-side control interface 1122, respectively. Thereby, the magnetic force line generating surface 141 having a circular shape in a plan view provided in the electromagnetic cooking unit 14 becomes a flat lower magnetic force line generating surface 141 attached to the surface of the mounting base 11. The fitting recess 112 of this example is a size that fits the electromagnetic cooking unit 14 in a close contact state, but juice is spilled from the heating container 15 depending on the cooking, or water droplets are generated by the ejection of water vapor described later, For example, the fitting recess 112 having a size that forms a gap with respect to the electromagnetic cooking unit 14 may be used, and the gap may be used as a water droplet pool.

  The gate-type support column 12 stands vertically from the mounting base 11, and includes a pair of left and right guide columns 121 for vertically guiding the raising and lowering of the movable base 13, and a reinforcing beam 122 installed horizontally on the upper ends of the pair of left and right guide columns 121. It consists of. For example, the portal column 12 is constructed by standing a pair of left and right mold steel members or angle members on a structural frame built in the mounting base 11, and laying a horizontal mold steel member or angle member on the upper end of the mold steel members or angle members. Thus, each mold steel material or angle material is covered with a decorative cover. Each guide column 121 is provided with a vertical guide groove 123 having a horizontal cross section square on the inner surface facing each other. The movable base 13 has engaging convex portions 132 having the same plan view shape as the vertical guide grooves 123 protruding from the left and right ends toward the vertical guide grooves 123, and the engaging convex portions 132 are projected to the vertical guide grooves 123. By making it fit, it can be moved up and down stably without rattling. Further, when there is a possibility that the movable base 13 may rattle during use due to the rotation of the unit holding part 131, a coil spring is interposed between the upper end (or lower end) of the guide column 121 and the upper surface (or lower surface) of the movable base 13. It is preferable to interpose a damper 133 for preventing rattling (see the phantom line in FIG. 3).

  The movable base 13 is moved up and down along a pair of left and right guide columns 121 constituting the portal column 12, and a unit holding part 131 is attached to the movable base 13 via a hinge 134 and attached to the unit holding part 131. The upper electromagnetic cooking unit 14 is moved up and down. The lifting means of the movable base 13 in this example uses a ball screw 136 that is rotated by a handle 135. The ball screw 136 is vertically supported by the bearing beam 137 built in each of the reinforcing beam 122 of the gate-type column 12 and the mounting base 11, and screwed with a lifting nut 138 built in the center of the movable base 13. . The ball screw 136 is rotated by attaching a detachable handle 135 to an operation bolt at the upper end protruding from the reinforcing beam 122, and the lifting nut 138 moves in the vertical direction according to the rotation of the ball screw 136. The movable base 13 incorporating the nut 138 moves up and down.

  The reason why the movable base 13 is moved up and down is to adjust the height of the upper electromagnetic cooking unit 14 relative to the lower electromagnetic cooking unit 14 according to the height of the heating container 15, but in practice, the movable base 13 is frequently moved. Since 13 is not lifted or lowered, it is sufficient that the ball screw 136 can be appropriately rotated manually using a detachable handle 135 as in this example. However, if there are many types of heating containers 15 and the height of the upper electromagnetic cooking unit 14 is frequently adjusted, for example, a motor 139 is connected to the upper end or lower end of the ball screw 136 to automatically rotate the ball screw 136. (Refer to a virtual line in FIG. 3).

  The movable base 13 is attached to the upper electromagnetic cooking unit 14 from the open front surface of the unit holder 131 that can be moved up and down. This unit holder 131 is located in the range including the fitting recess 112 of the mounting base 11. A front surface and a bottom surface are open with an outer shape similar to the mounting base 11, and a fitting groove portion 1311 extending in the front-rear direction is formed with a cross-sectional shape of the open front surface. Since the unit holding part 131 only needs to expose the magnetic force line generation surface 141 of the attached electromagnetic cooking unit 14, it is sufficient that at least the bottom surface is open. For example, the front surface is closed and the electromagnetic cooking is started from the opened lower surface. The unit 14 may be fitted upward. In this case, it is necessary to provide a means for preventing the electromagnetic cooking unit 14 from dropping on the inner peripheral surface of the opened lower surface.

  The unit holding part 131 of the present example is provided with an opening / closing handle 1312 on the upper edge of the opened front surface in order to manually operate turning up and down. Also, to stabilize the rotation of the unit holding part 131 that is cantilevered with respect to the movable base 13 so that the unit holding part 131 does not fall suddenly when the hand is released from the opening / closing handle 1312, for example. The unit holding part 131 is provided with a rotation restricting damper 1313 including a rack and pinion mechanism. The rack and pinion mechanism is configured by meshing a pinion built in the movable base 13 and an arc-shaped rack from the back surface of the unit holding part 131 toward the movable base 13. In addition, a rotation restricting damper 1314 including a coil spring that urges the unit holding portion 131 upward may be configured (see a virtual line in FIG. 4). The rotation restricting damper 1314 is configured, for example, by bridging a coil spring between the gate-type support 12 and the surface of the unit holding part 131. This rotation restricting damper 1314 made of a coil spring has the function of assisting the force at the time of flipping up the unit holding part 131 with the force of the coil spring in addition to the function of preventing the unit holding part 131 from abruptly falling down. .

  The fitting groove portion 1311 is provided with a pair of left and right horizontal guide flanges 1315 each having a bowl-like cross section on each inner side surface, a regulation roller 1316 that can be freely moved in and out near the insertion opening of the horizontal guide flange 1315, and electromagnetic cooking on the inner and rear surfaces A main body side power interface 1317 and a main body side control interface 1318 (see FIG. 8) for the unit 14 are provided. The main body side power supply interface 1317 and the main body side control interface 1318 are connected to the power supply unit built in the mounting base 11 or cords extending from the control unit directly from the mounting base 11 or via the movable base 13. However, in this example, it is omitted for convenience of illustration. The electromagnetic cooking unit 14 is inserted into the fitting groove 1311 from the front while pushing the regulating roller 1316, and a unit-side power interface 142 and a unit-side control interface 143 (see FIG. 8) provided on the back surface of the electromagnetic cooking unit 14 are They are connected to the main body side power interface 1317 and the main body side control interface 1318, respectively, and attached to the unit holding part 131 while restricting unexpected popping out by the restricting roller 1316 protruding again. As a result, the magnetic force line generating surface 141 having a circular shape in plan view provided on the electromagnetic cooking unit 14 becomes a flat upper magnetic force line generating surface 141 attached to the lower surface of the unit holding part 131.

  Next, the cooking procedure by the electromagnetic cooking device 1 of the present invention will be described by taking as an example the cooking of Kansai style okonomiyaki 2 (hereinafter referred to as okonomiyaki 2). FIG. 5 is a perspective view corresponding to FIG. 1 of the electromagnetic cooking device 1 showing a state in which the heating container 15 containing the dough 21 (including the ingredients) is placed on the magnetic force line generating surface 141 under the electromagnetic cooking unit 14. FIG. 7 is a sectional view showing the heating container 15 before cooking, and FIG. 7 is an electromagnetic diagram showing a state in which the movable base 13 is pivoted and lowered to sandwich the heating container 15 with the upper magnetic force line generation surface 141 and the lower magnetic force line generation surface 141. FIG. 8 is a perspective view corresponding to FIG. 1 of the cooking device 1, and FIG. 8 is equivalent to FIG. 3 of the electromagnetic cooking device 1 showing a state where the heating container 15 is sandwiched between the upper magnetic force line generation surface 141 and the lower magnetic force line generation surface 141 and cooked. FIG. 9 is a sectional view showing the heating container 15 during baking cooking, FIG. 10 is a perspective view equivalent to FIG. 1 of the electromagnetic cooker 1 showing the state in which the movable base 13 is rotated and raised after baking cooking, 11 is a perspective view corresponding to FIG. 1 of the electromagnetic cooker 1 showing a state in which the lid 151 of the heating container 15 is attracted to and removed from the magnet 1531 of the handle 153. FIG. 12 is a perspective view corresponding to FIG. 1 of the electromagnetic cooker 1 showing the state in which the container 152 of the heating container 15 is engaged with the hook 1532 of the handle 153, and FIG. It is a perspective view showing the state just before providing 2 to a customer.

  In this example, as shown in FIGS. 5 and 6, a dedicated heating container 15 suitable for cooking okonomiyaki 2 is used. The heating container 15 includes a metal lid 151 and a container 152. The lid 151 has a disc shape and the entire surface is a metal layer. In the lid body 151 of this example, a leaf spring 1512 protruding from the outer peripheral edge 1511 is fixed to the upper surface. The lid 151 is sized to be dropped into the container 152, but the plate spring 1512 is locked to the opening peripheral edge 1521 of the container 152 and is elastically supported by the plate spring 1512. The container 152 has a side surface 1522 that opens toward the opening peripheral edge 1521 having an inner diameter larger than that of the lid 151, and has a cross-sectional shape that is curved from the bottom surface 1523 to the side surface 1522. As a result, the okonomiyaki 2 that has been baked and cooked from the container 152 can be easily removed, and the container 152 can be easily washed. In the lid 151 of this example, the bottom surface 1523 itself is a metal layer.

  The movable base 13 is composed of a magnetic line of force generation surface 141 of the lower electromagnetic cooking unit 14 attached to the mounting base 11 and a magnetic force line generation surface 141 of the upper electromagnetic cooking unit 14 attached to the unit holding part 131 that is tilted and leveled. The height is adjusted in advance so that the interval becomes the thickness of the heating container 15. The height of the movable base 13 may be adjusted every time cooking is performed, but since it is generally considered that the same heating container 15 is used repeatedly, it is preferable to adjust the height in advance. The heating container 15 fills the dough 21 in which the ingredients are sufficiently mixed in the container 152, and closes the container 152 with the lid 151 so as to press against the dough 21. At this time, by making the fabric 21 less than the inner volume of the container 152, the lid 151 can lock the leaf spring 1512 to the opening peripheral edge 1521 of the container 152 and be lightly pressed against the fabric 21 while being elastically supported. (See FIG. 6). Then, when the heating container 15 containing the dough 21 is placed on the magnetic force generation surface 141 of the lower electromagnetic cooking unit 14, preparation for baking cooking is completed.

  In the electromagnetic cooker 1 of this example, the magnetic force line generating surface 141 of the electromagnetic cooking unit 14 attached to the mounting base 11 and the magnetic force line generating surface 141 of the electromagnetic cooking unit 14 attached to the unit holding part 131 have the same shape and a horizontal plane. Are in the same positional relationship. Further, as described above, since the height of the movable base 13 has been adjusted according to the heating container 15, when the unit holding part 131 is tilted with the heating container 15 placed on the lower magnetic force line generation surface 141, FIG. As shown in FIG. 8, the heating container 15 can be sandwiched between the upper and lower lines of magnetic force generation 141, 141. Here, since the lid 151 is dropped into the container 152, it does not come into full contact with the upper magnetic force generation surface 141, but is close to the upper magnetic force generation surface 141 and the magnetic force lines are sufficient. To reach. Further, since the bottom surface 1523 of the container 152 is in contact with the lower magnetic force line generation surface 141, the magnetic force lines are also sufficiently reached here. From this, the heating container 15 sandwiched between the upper and lower magnetic force line generation surfaces 141 can heat the lid 151 and the container 152, respectively, so that the dough 21 placed in the container 152 can be simultaneously heated up and down. Each electromagnetic cooking unit 14 starts to operate from an operation unit 111 provided on the front surface of the mounting base 11.

  At this time, the heating container 15 in which the lid 151 is dropped is in a substantially sealed state filled with only the fabric 21. However, by simultaneously heating up and down, the moisture contained in the dough 21 evaporates to become water vapor, and the air mixed in the dough 21 swells to increase the internal pressure, and as shown in FIG. By pushing up the lid 151, the gap between the side surface 1522 of the container 152 and the outer peripheral edge 1511 of the lid 151 can be increased, and water vapor can be released from the fabric 21 appropriately while releasing the internal pressure. The lid body 151 pushed up by the water vapor or air is restricted from being pushed up by the upper magnetic force line generation surface 141. This demonstrates the same function as baking okonomiyaki 2 while pressing dough 21 with a trowel. As described above, the electromagnetic cooker 1 of this example is used in combination with the dedicated heating container 15 so that water vapor is appropriately released from the dough 21 while pressing the dough 21 with a trowel. The okonomiyaki 2 can be baked in a short time and suitably by heating both sides simultaneously.

  As for the baking time, the operation time of each electromagnetic cooking unit 14 may be set in advance by a timer using the operation unit 111 provided on the front surface of the mounting base 11. That is, if each electromagnetic cooking unit 14 is deactivated by the operation of the timer, the cooking of the okonomiyaki 2 is completed. After completion of the baking, as shown in FIG. 10, the heating container 15 can be taken out if the unit holding part 131 is flipped up. However, in the heating container 15, the lid 151 and the container 152 are both heated and cannot be directly touched by the hand, and the magnetic field generating surface 141 must be in contact with or close to the lid 151 and the container 152, respectively. Therefore, the heating container 15 cannot be taken out as it is because no handle is provided in any of them. Therefore, in the present example, the handle 151 having the magnet 1531 and the hook 1532 is used so that the lid 151 and the container 152 can be taken out in this order.

  The handle 153 of this example includes a handle 1533 having a hook 1532 that engages with the opening periphery 1521 of the container 152 at the tip, and a flat plate-like magnet 1531 attached to the hook 1532. A perforated hook 1534 for suspending the handle 153 is provided at the rear end of the handle 1533. As shown in FIG. 11, the lid 151 has the magnet 1531 in contact with the handle 153 so that the handle 153 is adsorbed, and is removed from the container 152 with the handle 153. Since the magnet 1531 has a flat plate shape, it can be easily detached from the lid 151 by prying the handle 153. As shown in FIG. 12, the container 152 can be taken out from the lower magnetic force line generation surface 141 with the handle 153 by engaging the hook 1532 with the opening periphery 1521. The baked okonomiyaki 2 is completed at this stage by sprinkling sauce, green paste, bonito, etc., and mayonnaise, red ginger, ketchup (or aurora sauce), etc. according to taste.

  In the case of a restaurant using the electromagnetic cooker 1 of this example, the completed okonomiyaki 2 may be transferred to a separate plate and provided to the customer. However, since the container 152 in this example is a flat dish, for example, hold the handle 153 engaged with the hook 1532 and carry the okonomiyaki 2 in the container 152 to a table or the like, as shown in FIG. As described above, when the container 152 is placed on the table, the handle 153 can be removed, and the okonomiyaki 2 can be provided to the customer while being placed in the container 152. Such a method for providing okonomiyaki 2 has the advantage that the okonomiyaki 2 can be eaten hot without being cooled because the container 152 is heated by the electromagnetic cooker 1.

  The electromagnetic cooker based on this invention was made as an experiment, and the cooking time and cooking conditions required for cooking were confirmed for several types of food. The prototype electromagnetic cooker comprises a mounting base, a support column, a movable base, and a unit holding unit with commercially available frame shelves and angle materials, and the commercially available electromagnetic cooking device is used as an electromagnetic cooking unit for the mounting base and the unit holding unit. Fixed and configured. For this reason, the prototype electromagnetic cooker is configured to individually operate and stop the commercially available electromagnetic cookers that are the upper and lower electromagnetic cooking units, but the overall configuration based on the present invention is the same as the above example. . All of the commercially available electromagnetic cookers used as an electromagnetic cooking unit have a maximum output of 1400 W. When both electromagnetic cookers are used at their maximum output (1400 W + 1400 W), the strength is high. The case where it was used at the output (700W + 700W) was set to “weak”.

  The heating container used has the same configuration as the above example, and the lid and container are each made of iron with a thickness of 1 mm, the lid is a disk with an outer diameter of about 18 cm, and the container has an opening edge of about 18 cm in inner diameter and a depth of about 2 cm. It is a flat dish. The lid is about 20 cm long, about 1.5 cm wide, and 0.5 mm thick, along the diameter. The leaf spring is fixed only at the center of the lid, and both ends of the leaf spring are connected to the outer periphery. It protrudes about 1cm from. The container has a curved cross section from the bottom surface to the side surface, and the effective bottom surface where the bottom surface is in contact with the lower magnetic force line generation surface has a diameter of about 15 cm. Using this heated container, Hiroshima-style okonomiyaki, Kansai-style okonomiyaki, salmon fillet (about 12 mm thick), salmon fillet (about 17 mm thick), and beef steak (about 15 mm thick) were baked.

  For Hiroshima-style okonomiyaki, dough and ingredients were placed in a heating container as follows, and baked with a prototype electromagnetic cooker. The heating container is coated with oil on the lid and the container. First, place the dough on the container and place the pork. Place the cabbage on the dough and the pork. Place the raw eggs on the cabbage. A lid was placed. The heating container with the dough and the ingredients is in a state where the lid is lifted from the container by the cabbage, but it is placed on the lower magnetic field generating surface and pushed down by the upper electromagnetic cooking unit. It can be compressed to a state where the lid is covered. That is, the dough is in close contact with the container, and the cabbage and eggs are in close contact with the lid. By baking the dough and the ingredients in the heating container in this way for 3 minutes with “strong” and 5 minutes with “weak”, the thickness is about 2 cm (= corresponding to the depth of the body) with moderate burns on both sides. I was able to bake Hiroshima-style okonomiyaki.

  For Kansai-style okonomiyaki, dough and ingredients were placed in a heating container as follows, and baked with an experimental electromagnetic cooker. The heating container was coated with oil on the lid and the container, and then the dough mixed with cabbage, pork and other ingredients was placed in the container, and the lid was covered. The Kansai-style okonomiyaki is not covered with cabbage like the above-mentioned Hiroshima-style okonomiyaki, so the lid has been placed on the container from the beginning. That is, the cloth and the tool are in close contact with the lid and the container, respectively. By baking the dough and the ingredients in the heating container in this way for 3 minutes with “strong” and 5 minutes with “weak”, the thickness is about 2 cm (= corresponding to the depth of the body) with moderate burns on both sides. I was able to bake Kansai-style okonomiyaki.

  Salmon fillets (about 12mm thick) were placed in a heating container as follows, and baked with a prototype electromagnetic cooker. The heating container was coated with oil on the container, and a salmon fillet was placed on the container and covered with a lid. Since the used salmon fillet is sufficiently lower than the depth of the container, there is no possibility of contact with the lid, and therefore the lid is not oiled. From now on, the salmon fillet is in close contact with the container only. By cooking the salmon fillets in the heating container in this way for 2 minutes with “strong” and 4 minutes with “weak”, the salmon fillets with appropriate burnt on both sides could be baked. It is considered that the burnt surface of the salmon fillet is due to the heat radiation of the heated lid. Further, since the heating container forms a sealed space, the oil scatters in the heating container, and the side surface of the salmon fillet is also burned by the oil.

  Salmon fillets (about 17mm thick) were placed in a heating container as follows, and baked using a prototype electromagnetic cooker. The heating container was coated with oil on the lid and the container, and the salmon fillet was placed on the container and covered with the lid. The salmon fillets used are lower than the depth of the container, but the lid is also oiled because the lid is dropped into the container and may contact the lid. From this, the salmon fillet is in contact with the lid and the container. By cooking the salmon fillets in the heating container in this way for 2 minutes 30 seconds at “strong” and 5 minutes at “weak”, the salmon fillets with moderate burns on both sides could be baked. The burnt surface of the salmon fillet is due to the direct contact of the lid, and the skin was burnt particularly fragrant. Further, as described above, the oil splattered in the heating container, and the side surface of the salmon fillet was burnt with the oil.

  Beef steak (about 15mm thick) was placed in a heating container as follows, and baked with a prototype electromagnetic cooker. The heating container was coated with oil on the lid and the container, and then beef steak was placed on the container and covered with the lid. Although the used beef steak is lower than the depth of the container, the lid is oiled because the lid is dropped into the container and may contact the lid. From this, the beef steak is in contact with the lid and the container. By cooking the beef steak meat in the heating container in this way for 1 minute 40 seconds at “strong” and 3 minutes at “weak”, it was possible to bake beef steak with moderate burns on both sides. The charred surface of the beef steak is due to the direct contact of the lid. Further, as described above, the oil splattered in the heating container, and the side surface of the beef steak was burned with the oil.
