From each detection means, the state of the food and the heating chamber are controlled. Then, each heating means and driving means are operated as necessary.

  This embodiment is configured as described above, and an operation example in the case of steaming six annular steamed donuts as the object to be cooked 130 will be described with reference to FIGS. 14 to 16.

  Steamed donuts are made by mixing ingredients and fermenting to make dough. After resting the dough, the dough is made into a rod-like shape by connecting both ends and placed on an oven sheet 131 and fermented again. The dough that has been fermented is placed on the oven sheet 131, moved to the tray 111 and arranged. Then, as shown in FIG. 11, the steamer 125 in which steamed donuts of the object to be cooked 130 are arranged, the table plate of the heating chamber 28 with the steam port 102 facing the steam outlet 44 as shown in FIG. 24. Then, water is supplied to the water supply tank 50, set in the main body 1, the door 2 is closed, and cooking is started.

  As shown in FIG. 14, when the heating start button is operated, the steamed donut is cooked by the control process 300 including the steam process 301 and the subsequent steam + range process 302. Here, the heating time t1 of the steam process 301 is about 14 minutes 30 seconds, and the heating time t2 of the steam + range process 302 is about 1 minutes 30 seconds.

  The steam process 301 is a heating process in which the steamed donut is steamed using the steam from the steam unit 43a. In this steam process 301, steam at about 100 ° C. is supplied, and the inside of the steamer 125 is filled with water vapor at about 80 ° C., and the tray 111 is heated to about 50 ° C. due to the contact of water vapor. As shown in FIG. 15, the full steam is first steamed on the outer peripheral surface 130 a and the inner peripheral surface 130 b of the steamed donut, and part of the steam is condensed water and is transmitted through the grill pan lid 101 and the oven sheet 131. It collects in 111 and prevents that the surface dries dry. Thereafter, heat is gradually transferred from the outer peripheral surface 130a and the inner peripheral surface 130b to the inside, and steams up to the core 130c. Since the annular steamed donut is heated by water vapor from both the outer peripheral surface 130a and the inner peripheral surface 130b, when the outer peripheral surface 130a and the inner peripheral surface 130b reach a high temperature, heat is quickly transferred to the inner core 130c. FIG. 14 shows an example in which the steam unit 43a continuously supplies water vapor in the steam process 301, but it may be configured to intermittently supply water vapor.

  When the steam process 301 is completed, a steam + range process 302 is performed. The steam + range process 302 is a heating process in which the steam unit 43a and the range heating means 77 driven at about 350 W are used in combination. In this step, as in the steam step 301, the steam is supplied substantially continuously and the cooking of steaming the donut with the steam is continued. At the same time, the high-frequency heating element 120 provided on the back surface of the tray 111 absorbs the microwave supplied from the magnetron 33 and generates heat, and the metal dish part 112 becomes high temperature. Steamed donuts are cooked. Thereby, the temperature of the bottom portion 130d of the steamed donut rises. In this way, the steam + range step 302 is for cooking with heat from the saucer 111 while filling the interior of the steamer 125 with water vapor, so that the end of cooking is prevented while drying the object 130 to be cooked. The texture of the finish can be improved and the taste and flavor can be maintained. And the steam generation means 43 and the range heating means 77 are stopped simultaneously, and cooking is complete | finished.

  In the steam + range process 302, the metal dish 112 is heated by the high-frequency heating element 120, so that the surface temperature of the saucer 111 is about 70 ° C., and the bottom 130d of the placed cooking object 130 is heated. . The heat of the tray 111 heated by the range heating means 77 is also transmitted to the grill pan lid 101, but the grill pan lid 101 is formed of a metal material that does not transmit microwaves. Since the heat of the tray 111 is not easily transmitted by the lid packing 104 provided on the outer periphery of the lower end of the 101, the grill pan lid 101 is not easily heated even when the range heating means 77 is driven. Therefore, since there are few heat rays from the grill pan lid 101, it is suitable for cooking like a steamed donut which heats without baking color.

  The steamed donut cooking in the steam + range process 302 will be described in more detail with reference to FIG. As shown here, in the steam + range step 302, the bottom 111 is attached to the bottom portion 130d of the to-be-cooked item 130 arranged on the receiving plate 111 and the to-be-cooked item 130 is heated by the receiving plate 111. Moisture 133 at the bottom of the inside of the cooking object diverges around the bottom 130d of the cooking object and moves away from the cooking object. And the water | moisture content of the outer peripheral surface 130a of the to-be-cooked object 130 formed in a ring shape, the inner peripheral surface 130b, the bottom part 130d, and the core 130c becomes substantially uniform, and the water wetness of the surface is eliminated. As described above, the temperature of the saucer 111 is about 70 ° C., but at this temperature, the steamed donut is rapidly heated to cause no coloring, and the bottom portion 130d of the cooking object 130 and the surrounding moisture are evaporated. be able to. That is, the steamed donut can be prevented from becoming vicious by the water accumulated on the bottom 130d after adhering to the outer peripheral surface 130a and the inner peripheral surface 130b of the object 130, and the sweetness contained in the steamed donut It prevents the ingredients and fragrances from flowing into the water collected at the bottom.

  Further, the weight of the steamed donut placed on the tray 111 is measured by the weight detection means 25 provided at the bottom of the table plate 24 by the control means 151, and the heating time of the steam process 301 and the heating of the steam + range process 302 are measured. It becomes possible to adjust the time.

  As described above, according to the heating cooker of the present embodiment, the whole cooked food can be uniformly steamed, is not watery, has a texture suitable for confectionery, maintains the taste and flavor, and has a good finish. It becomes possible to do.
