  Reference numeral 151 denotes a control unit which is mounted on the control board 23 and operates to cook food according to the contents input from the input unit 71. The state of the food and the state of the heating chamber are detected from each detection unit. Then, each heating means and driving means are operated as necessary.

  The present embodiment is configured as described above. Next, an operation example in the case where okonomiyaki is baked as the cooking object 128 will be described with reference to FIGS. 18 and 19.

  The ingredients to make okonomiyaki are two pieces that can be baked at one time, and the dough is 120 g long (grated), 1 egg, 1 and 1/2 tablespoon soup stock, 50 g flour (soft flour), cabbage (1 cm square chopped) 120 g, 10 g of small onion (small cut), 10 g of tempura, 10 g of red ginger, and 100 g of sliced pork belly.

  As shown in FIG. 5, the metal legs 114 are supported by the resin legs 113 a, the metal legs 114 are folded and stored, and the overhanging portions 119 are placed on the metal tray 112 of the tray 111 that protrudes outside the left and right end surfaces 112 e of the metal tray 112. Arrange two pieces of pork belly with a diameter of about 14 cm and place the dough so that it does not protrude from the pork belly.

  Then, as shown in FIG. 13, the tray 111 on which the object 128 is placed is placed on the shelf upper stage 27 a of the heating chamber 28 by the overhanging portion 119, the door 2 is closed, and cooking is started.

  “Okonomiyaki” is selected by the operation unit 6 and the heating start is operated.

  As shown in FIG. 18, the process 300 is a control for performing a two-stage process including a grill process 301 and a range process 302.

  Generally, the heating time for cooking two okonomiyaki at a time is about 13 minutes for the heating time T1 of the grilling process 301 and about 6 minutes for the heating time T2 of the range process 302. The heating time T1 of the grilling process 301 is a time during which the upper surface 130a of the to-be-cooked item 128 is baked by about 80 to 90%.

  The grilling process 301 is a heating process in which the controller 151 causes the grill heating unit 12 to heat the okonomiyaki upper surface 128 a, which is the object to be cooked 128, with the radiant heat of the grill heating unit 12. As shown to Fig.19 (a), it heats from the upper surface 128a of the to-be-cooked item 128, ie, the surface of dough, gelatinizes wheat flour, and cabbage etc. are heated. Thereafter, the core 128c is gradually heated. As the flour is gelatinized, the vitamins from the cabbage and pork belly are received and cooked without losing the deliciousness and nutrition.

  In addition, the saucer 111 (the portion on which the object to be cooked 128 is not placed) is also heated by the radiant heat from the grill heating means 12, and the lower surface 128b side of the object to be cooked 128 is also heated by the high-frequency heating element 120 on the lower surface of the saucer 111 and heat conduction. Is done.

  At the end of the grilling process 301, the temperature of the portion of the metal dish portion 112 where the item 128 to be cooked is not placed rises as in the heating chamber 28. The upper surface 128a of the okonomiyaki dough is baked to such an extent that it can be gelatinized to give a baked color. At this time, the water content of the item 128 is also greatly reduced.

  Next, the range process 302 is performed. The range step 302 is a control method in which the control unit 151 performs microwave heating of the range heating unit 77. The high-frequency heating element 120 provided on the back surface of the metal dish part 112 of the tray 111 absorbs the microwave radiated from the magnetron 33 and generates heat, thereby transferring heat to the metal dish part 112.

  As shown in FIG. 19 (b), the lower surface 128b of the okonomiyaki is heated from the metal dish portion 112, and the pork belly, which is the lower surface 128b of the okonomiyaki, is cooked and colored.

  Since the dough placed on the upper side of the pork belly is almost lit in the grilling process 301, the range process 302 operates only the range heating means 77, so that the upper surface 128a of the object 128 can be heated unnecessarily. Since the upper surface 128a of the object 128 is not hardened, only the lower surface 128b is heated to the extent that it is not burnt, and the metal dish 112 is heated while cooking the object 128 to be dried. It is a process that improves the texture of the finished finish and maintains the taste and flavor.

  Then, the range process 302 is executed next to the grilling process 301, so that the grilling process 301 generally heats the inside of the article 128 to be cooked, and heats the air in the heating chamber 28 and the metal dish part 112 to a high temperature. The subsequent heating of the high-frequency heating element 120 by microwaves does not require an increase in the temperature of the entire metal dish 112, and heat is not lost from the metal dish 112 to the heating chamber 28. It is only necessary to heat the lower surface 128b of the to-be-cooked item 128 that is generally lit. Therefore, it is not necessary to set the microwave output to a large heating power, and it is not necessary to heat for a long time. As described above, the microwave wraps around the upper surface of the saucer 111, and the upper surface 128a of the object 128 to be cooked unnecessarily. Is not heated, so that the upper surface 128a of the object 128 is not hardened.

  As a result, the surfaces of the upper surface 128a that is the dough 128 to be cooked and the lower surface 128b that is pork belly are heated, the dough is gelatinized and the nutrition is not lost, and the surface is baked to give the core 128c. It is baked nicely with a crisp texture, with a crisp texture.

  As a cooking method, okonomiyaki, which is a typical menu of teppanyaki, has been described as an example, but Chijimi can be baked deliciously in the same process.

  When cooking using the saucer 111, the position of the saucer 111 is properly used depending on the cooking method.

  The cooking method is to use the range heating means 77 mainly at the time of cooking, that is, to cook the food directly by microwave while baking the food by raising the temperature of the heating high-frequency heating element 120 by microwave. This is the case when it is necessary to heat the object. The usage of the tray 111 at that time is performed by folding the metal legs 114 of the tray 111 inward and placing the resin legs 113a of the tray 111 on the table plate 24 as shown in FIG. At this time, as shown in FIG. 11B, the protruding portion 119 is rotated and fitted and fixed to the notch 113k provided in the resin leg portion 113a. When the overhanging portion 119 is fitted and fixed to the notch portion 113k, the overhanging portion 119 is held by friction between the side surface inclined portion 119t of the overhanging portion 119 and the side surface 113s of the notch portion 113k.

  Further, during cooking, the food to be cooked is directly heated by the microwave while baking the food by heating the high-frequency heating element 120 by the grill heating by the grill heating means 12 and the microwave by the range heating means 77. Is necessary. As shown in FIG. 15, the metal tray 114 of the tray 111 is opened and placed on the table plate 24 using the metal legs 114 of the tray 111 for cooking. Also in this case, the overhanging portion 119 is rotated and fitted and fixed to the notch portion 113k provided in the resin leg portion 113a. When the overhanging portion 119 is fitted and fixed to the notch portion 113k, the overhanging portion 119 is held by friction between the side surface inclined portion 119t of the overhanging portion 119 and the side surface 113s of the notch portion 113k.

  Furthermore, it is a case where baking heating by the grill heating means 12 is mainly required during cooking. The usage of the tray 111 at that time is as shown in FIG. 13, in which the overhanging portion 119 provided on the tray 111 is opened and placed on the shelf upper stage 27a for cooking.

  In the above three cooking methods, when the range heating unit 77 is mainly cooked, the microwave is irradiated to the object to be cooked 128 and heated, so the range heating unit 77 is approximately proportional to the mass of the object to be cooked 128. It is necessary to adjust the heating time. Therefore, the heating time can be adjusted by placing the tray 111 on the table plate 24 and detecting the weight of the cooking object 128 using the weight detection means 25.

  When the grill heating means 12 is mainly cooked, it is necessary to prevent the food to be cooked 128 from drying by cooking in a short time with a strong fire with the heater of the grill heating means 12. Therefore, in order to reduce the gap provided between the wall surface of the heating chamber 28 for supplying microwaves to the upper surface of the receiving tray 111 and the receiving tray 111 and improve the heating efficiency above the receiving tray 111, A tray 111 is provided at the position of the shelf 27 projecting inward, and the projecting portion 119 is opened to eliminate a gap between the tray 111 and the shelf 27. Further, by positioning the tray 111 upward, the ratio of the microwave supplied above the tray 111 is weakened to prevent the cooking object 128 from being heated and dried by the microwave.

  As described above, according to the present embodiment, the tray 111 having the high frequency heating element 120 and mounted on the shelf upper stage 27a of the heating chamber 28 and the height of the tray 111 provided with the high frequency heating element 120 and mounted on the uppermost shelf upper stage 27a of the heating chamber 28 are provided. It is equipped with a saucer 111 that measures the weight by placing it at a lower height, and the functions of both saucers, so it saves the trouble of using the saucer separately by cooking, and the saucer 111 can accommodate multiple heights in the heating chamber 28, and vibrates. It is possible to prevent the generation of abnormal noise due to.
