Subsequently, cooking utensils and liquids such as water and milk are put into the work bowl 160. Then, the lid 170 is attached to the work bowl 160. Finally, desired operation buttons 131a to 131d are pressed on the operation panel 131 to start cooking. When cooking is started, the cooking blade 150 rotates to cut the food, or the food is heated by electromagnetic induction heating by the work coil 137.

  Hereinafter, each operation of the food processor when the “drinking soup” button 131b is pressed by the user, the “eat soup” button 131c is pressed, or the “warm and reheat” button 131d is pressed is described in detail. To do. If the user presses the “pause” button 131e after pressing the operation buttons 131b to 131d, the cooking process or the reheating process is paused, and if the “cancel” button 131f is pressed, the cooking process or the reheating process is stopped. Processing is completely stopped. Further, when the cooking container 161 is no longer detected by the cooking container detection sensor 114b, all subsequent processes are automatically canceled.

Operation of the food processor when the “Drinking soup” button is pressed First, when the “Drinking soup” button 131b is pressed by the user, the microcomputer 136A performs a confirmation process, a preliminary heating process, a preliminary cutting process, a finishing process, A 1st heat retention process, a reheating process, and a 2nd heat retention process are performed in order (refer FIG. 6). Hereinafter, the operation | movement aspect of the food processor in each process is explained in full detail.

(1) Checking Step In this step, the microcomputer 136A first acquires information on the temperature of the cooking vessel 161 from the temperature sensor 114a. And if the temperature of the cooking container 161 is below a predetermined threshold value, the microcomputer 136A will rotate the motor 132 at high speed only for t31 seconds. This high-speed rotation is performed in order to confirm whether or not the lid 170 is normally attached. That is, liquid such as water does not leak from the lid 170 when the lid 170 is normally attached, and liquid such as water leaks from the seal portion when the lid 170 is not normally attached. put out. In the latter case, the user remounts the lid 170 or confirms the packing. In such a case, the work coil 137 is not energized for t11 (> t31) seconds from the start of this process. On the other hand, when the temperature of the cooking container 161 exceeds a predetermined threshold value, the microcomputer 136A cancels all subsequent steps.

(2) Preheating step In this step, the microcomputer 136A first applies 100% power to the work coil 137 until t12 seconds elapse from the start of this step with the motor 132 stopped. The ingredients in the cooking container 161 are heated. At this time, the microcomputer 136A performs the emptying detection based on the information on the temperature rise rate. The microcomputer 136A continues to apply 100% electric power to the work coil 137 to heat the ingredients in the cooking container 161 after the previous operation ends, but the temperature value T from the temperature sensor 114a is the first value. This step is terminated when 1 threshold value Ts11 or more is reached, or when t13 seconds have passed since t12 seconds have passed.

  In this step, the heating times t12 and t13 and the first threshold value Ts11 that is the heating stop temperature condition are necessary for the rotary blade 152 to be able to cut the material almost uniformly in the preliminary cutting step.

Then, the microcomputer 136A ends this operation when the temperature value T from the temperature sensor 114a becomes equal to or higher than the third threshold value Ts13 or when t20 seconds have elapsed from the start of this process. Thereafter, the microcomputer 136A supplies 50% of electric power to the work coil 137 with the motor 132 stopped until t21 seconds elapse from the end of the previous operation, and the ingredients in the cooking container 161 are removed. Continue heating.
