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 of cooking okonomiyaki as the object to be cooked 130 will be described with reference to FIGS. 14 to 15.

  The ingredients to make okonomiyaki are 2 pieces that can be baked at one time, the dough is 120g long (grated), 1 egg, 1 and 1/2 tablespoon soup stock, 50g flour (soft flour), cabbage (1cm square chopped) 120g, 10g of small onion (small cut), 10g of tempura, 10g of red ginger, and 100g 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 14cm and place the dough so that it does not protrude from the pork belly.

  Then, as shown in FIG. 10, the tray 111 on which the cooking object 130 is placed is placed on the shelf upper stage 27 a of the heating chamber 28 by the projecting 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. 14, 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 object to be cooked 130 is baked by about 80 to 90%.

  The grilling process 301 is a heating process in which the control unit 151 uses the grill heating unit 12 to heat the okonomiyaki upper surface 130 a, which is the object to be cooked 130, with the radiant heat of the grill heating unit 12. As shown to Fig.15 (a), it heats from the upper surface 130a of the to-be-cooked object 130, ie, the surface of dough, gelatinizes wheat flour, and cabbage etc. are heated. Thereafter, the core 130c 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 tray 111 (the portion where the object 130 is not placed) is also heated by the radiant heat generated by the grill heating means 12, and the lower surface 130b side of the object 130 is also heated by the high-frequency heating element 120 on the lower surface of the tray 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 cooking object 130 is not placed rises as in the heating chamber 28. The upper surface 130a of the okonomiyaki dough is baked to such an extent that it becomes gelatinized and has a baked color. At this time, the water content of the object 130 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. 15 (b), the bottom surface 130b of the okonomiyaki is heated from the metal dish part 112, and the pork belly, which is the bottom surface 130b of the okonomiyaki, is cooked to give a grilled color.

  Since the dough placed on the upper side of the pork belly is substantially lit in the grilling process 301, the range process 302 operates only the range heating means 77, so that the upper surface 130a of the object 130 can be heated unnecessarily. Since there is no such thing, the upper surface 130a of the object 130 is not hardened and only the lower surface 130b is heated to the extent that it is not burnt, and the metal dish portion 112 is heated and cooked while preventing the object 130 from drying. 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 grill process 301, so that in the grill process 301, the inside of the article to be cooked 130 is generally heated, and the air in the heating chamber 28 and the metal dish portion 112 are heated 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 sufficient to heat the lower surface 130b of the object 130 to be cooked, which 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 130a of the object 130 to be cooked unnecessarily. The upper surface 130a of the object 130 is not hardened.

  As a result, the surfaces of the upper surface 130a, which is the dough of the cooked material 130, and the lower surface 130b, which is pork belly, are heated, the dough is gelatinized and the nutrition is not lost, and the surface 130c is colored. 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 object 130 by raising the temperature of the high-frequency heating element 120 by microwave. This is a case where it is necessary to heat the object 130. 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.

  Further, at the time of cooking, the cooking object 130 is directly heated by the microwave while baking the cooking object 130 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. If that is necessary. As shown in FIG. 12, 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.

  Furthermore, it is a case where baking heating by the grill heating means 12 is mainly required during cooking. The usage of the saucer 111 at that time is as shown in FIG. 11, in which the overhanging portion 119 provided on the saucer 111 is opened and placed on the shelf upper stage 27a for cooking.

  In the above-described three cooking methods, when the range heating means 77 is mainly cooked, the microwave is applied to the object to be cooked 130 and heated, so the range heating means 77 is approximately proportional to the mass of the object to be cooked 130. 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 object to be cooked 130 using the weight detection means 25.

  Further, when the grill heating means 12 is mainly cooked, it is necessary to prevent the food to be cooked 130 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 130 from being heated and dried by the microwave.

  As described above, according to the present embodiment, the tray 111 having a height that is provided with the high-frequency heating element 120 and placed on the uppermost shelf 27a of the heating chamber 28, and the uppermost shelf upper stage 27a of the heating chamber 28 that includes the high-frequency heating element 120. It is equipped with a tray 111 that measures the weight by placing it at a height lower than the height placed on the pan, and the function of both pans is provided, eliminating the need to use different pans for cooking, and the pan 111 corresponds to multiple heights in the heating chamber 28 It becomes possible to do it.
