FIG. 3 is a block diagram showing the control system of this embodiment. Reference numeral 30 denotes a control unit which receives a microcomputer board 34 having a microcomputer 32 having a built-in memory 31 and an operation panel 33, a motor drive circuit 35 for driving a motor, a heater drive circuit 36 for driving a heater, and a temperature sensor signal. And a power board 39 provided with a temperature detecting circuit 37 and a buzzer 38 for detecting the temperature. Among these, the motor drive circuit 35 is provided with a speed variable circuit 40 that varies the energization rate to the motor and changes the relative rotational speed, and a load detection circuit 41 that detects the rotational load of the motor. The speed variable circuit 40 intermittently cuts off the energization of the motor in units of power supply cycles, and raises and lowers the relative rotation speed depending on the length of the cut-off cycle. That is, as shown in FIG. 4, when the motor is energized only for the first 3 cycles in the 16 cycles of the power supply waveform and the subsequent 13 cycles are cut off, the motor starts rotating at a lower rotational speed than the fully energized state. . Therefore, the rotational speed can be adjusted by changing the energization cycle and the cutoff cycle in the 16 cycles. The load detection circuit 41 detects an electromotive force generated by the rotation of the motor and determines whether the motor is rotating or stopped. That is, as shown in FIG. 4, if the electromotive force generated by the rotation of the motor during the motor cutoff cycle obtained by the speed variable circuit 40 is equal to or greater than a certain value, the motor is rotating. It is determined that the motor is not in a state, and if it is lower than a certain value, it is determined that the motor is stopped, that is, locked by a load.
[0018]
The operation panel 33 includes an LCD display panel 42, a menu key 43 for selecting a cooking menu, a start key 44 for starting and restarting cooking, a stop key 45 for stopping operation and canceling settings, and a reservation. A reservation timer key 46 for setting the cooking time is provided. On the display panel 42, the cooking time, the number of the cooking menu selected by the menu key 43, and the like are displayed.
[0019]
In this cooking machine, there are various bread menus from kneading to baking, ice cream menus from heating and stirring to cooling, gelato, sherbet, frozen yogurt menu that performs only cooling, and heating and stirring only. The menu includes cream, jelly, pudding, and jam menus, and motor and heater drive data necessary for each menu is written in the memory 31 of the microcomputer 32.
[0020]
Next, the operation of the present invention configured as described above will be described for each menu selected by the menu key 43. First, when various bread making menus are executed, necessary materials are set in the heating container 16 and attached to the cooking chamber 3 by the above method as shown in FIG. When the desired bread making menu is selected with the menu key 43 (setting a reservation timer if necessary) and the start key 44 is input, the motor 4 is driven and the kneading blade 19 rotates to knead the material. In addition, the dough is fermented while the temperature in the cooking chamber 3 is maintained at the fermentation temperature by the heater 13 and the temperature sensor 14, and finally the dough is baked to make bread.
[0021]
When the cooling menu is executed, necessary materials are set in a cooling container 21 that has been frozen in advance as shown in FIG. When the desired cooling menu is selected with the menu key 43 and the start key 44 is input, the motor is driven to rotate the stirring blade 24, the material is cooled while being stirred and frozen, and gelato, sherbet, frozen yogurt, etc. Can be made.
[0022]
Next, a case where the ice cream menu is executed will be described. When making ice cream, it is necessary to first sterilize the milk, sugar, fresh cream, and egg yolk, which are ingredients, at a temperature of about 70 ° C., lower it to a certain temperature, and then cool it. Therefore, first, the material is set in the heating container 16 and attached in the cooking chamber 3. When the ice cream menu is selected with the menu key 43 and the start key 44 is input, the motor 4 is driven to rotate the kneading blade 19 and the inside of the cooking chamber 3 is heated to the sterilization temperature by the heater 13 and the temperature sensor 14. The material is heated and stirred. When this process is finished, the buzzer 38 is turned on, the replacement of the material container is notified, and the apparatus is temporarily stopped. Therefore, the heating container 16 is taken out from the cooking chamber 3, transferred to the cooling container 21 in which the material has been cooled in advance, and the cooling container 21 is attached in the cooking chamber 3. When the start key 44 is input again from this state, the motor 4 is driven and the stirring blade 24 rotates, and the ice cream is made by solidifying the material while freezing.
[0023]
In addition, since the cooking machine of the present invention cooks by using the heating container 16 and the cooling container 21 according to each menu, in order to prevent the wrong material container from being set, The control unit 30 determines whether or not the attached material container corresponds to the selected menu based on the temperature change that occurs until the predetermined time elapses after the start key 44 is pressed.
[0024]
Each menu executed in this way is executed according to the time stored in the memory 31 and the set temperature. Of these, motor drive control during the cooling process will be described with reference to the flowchart of FIG. In the cooling process, the material is gradually solidified from the contact surface with the cold storage agent by slowly stirring the material, so the motor 4 is first driven at a low speed. That is, the motor is driven at the lowest speed L1 by the speed variable circuit 40 of the motor drive circuit 35 (1). When the material hardens, a load is applied to the motor 4, and as a result, the load detection circuit 41 detects an overload state of the motor 4 (2). When an overload of the motor 4 is detected, the speed variable circuit 40 rotates at a speed L2 higher than the speed L1 (3). Such control is repeated, and the speed is increased step by step every time the motor is overloaded. When the motor overload is detected at the speed L5, the operation is ended (4).
[0025]
As a result, the material gradually solidifies, and it is possible to make fine ice cream, and the motor is not locked in a chronic state, and the motor is not burdened. Therefore, it is possible to provide an extremely excellent cooking machine capable of performing cooking that has been performed by using a separate apparatus until now only by replacing the material container with a menu.
[0026]
【The invention's effect】
The present invention is configured as described above, and is provided with a container for heating and cooking and a container for cooling and cooking. Cooling cooking can be performed, and the number of menus that can be implemented is greatly increased, so that it can be used for a wide range of purposes. Moreover, since the material container is simply replaced according to the selected menu, the configuration is simple and easy to use, and anyone can use it easily. Furthermore, in the cooling process of ice cream or the like, the speed of the motor is increased according to how the material is solidified, so that a fine ice cream can be made.
