The means 89 and the pump means 87 are controlled. Here, the input means 71 shows the operation unit 6 and the display unit 5.

  The control means 151 is mounted on the control board 23 and operates to cook food according to the contents input from the input means 71. The control means 151 detects the state of the food and the state of the heating chamber from each detection means. Thereafter, each heating means and driving means are operated as necessary.

  The stirring motor 54 rotates the kneading blade 51 of the stirring container 50 to knead the food 57 in the stirring container 50.

  The solenoid 98a operates the yeast charging means 95 and the solenoid 98e operates the material charging means 96.

  The present embodiment has the above-described configuration, and mochi making will be described in detail.

  First, the kneading blade 51 is set in the stirring vessel 50, the glutinous rice (320 g as two portions) and water (280 to 320 mL) are put into the stirring vessel 50, the table plate 24 of the heating chamber 28 is removed, and the bottom of the heating chamber The agitation container 50 is mounted with the mounting guide 56 placed on 28a.

  After setting the stick with the input means 71, the start of cooking is started by inputting a start key (not shown) for starting cooking.

  The rice-making process is roughly divided into a “cooking process” and a “kneading process”, and the “cooking process” includes a “pre-cooking process” and a “post-cooking process”.

  In the “pre-cooking process”, electric power is supplied to both the hot air heater upper 14a and the hot air heater lower 14b of the hot air unit 11, and the hot air 63 heated from both the hot air outlet 30a and the hot air outlet 30b is heated in the heating chamber. 28, the hot air 63 is circulated, and the glutinous rice put in the stirring vessel 50 is cooked. In the cooking control, the temperature of the heating chamber 28 is detected by the control means 151 by the temperature detection means 85 to indirectly capture the temperature of the stirring vessel 50, and the power is controlled to both the hot air heater upper 14a and the hot air heater lower 14b. Heat the glutinous rice to 80 degrees.

  When heated to 80 degrees, the water put in the stirring vessel 50 is absorbed by the glutinous rice and almost disappears, and stickiness appears on the surface of the glutinous rice.

  At this stage, a hard core remains in the center of glutinous rice. Since the stirring container 50 matches the size of the baked bread with the size of a commercially available bread, it has a rectangular parallelepiped with a deep depth, so that it is difficult to cook glutinous rice evenly. Therefore, there is a problem that the surface of the glutinous rice is dried and hardened even if heating is continued until the core disappears in this state.

  Therefore, when the water put in the stirring vessel 50 is absorbed by the glutinous rice and almost disappears and stickiness comes out on the surface of the glutinous rice, the process proceeds to the “post-cooking step” which is the next step.

  The “post-cooking process” is a process in which cooking is continued in order to eliminate the hard core of the remaining glutinous rice. In the cooking of this process, in order to prevent drying of the surface of the rice, the supply of power to the hot air heater upper 14a of the hot air unit 11 is stopped so that hot air does not enter from the opening above the stirring vessel 50, By controlling the power supplied to the hot air heater 14b, hot air 63 heated by the hot air heater 14b from the hot air blowing hole 30b is put into the heating chamber 28 and the lower part of the stirring vessel 50 is heated to dry the rice. Prevention, the stirring motor 54 is driven and the kneading blade 51 is rotated to remove the surface portion of the glutinous rice that has been softened by stirring the glutinous rice so that heat is easily transmitted to the central portion of the glutinous rice.

  When the whole glutinous rice becomes soft, it moves to the next “kneading process”.

  In the “kneading step”, heating of the stirring vessel 50 is stopped, the stirring motor 54 is driven, the kneading blade 51 is rotated, and kneading is performed until the soft glutinous rice becomes glutinous.

  The time required for each process is about 20 minutes for the “pre-cooking process”, about 50 minutes for the “post-cooking process”, and about 10 minutes for the “kneading process”, and the entire process takes about 80 minutes.

  As described above, according to this embodiment, there is an effect of eliminating the uneven cooking of glutinous rice and making good glutinous rice.
