M and 53 are control devices including a motor drive unit 55 that drives the motor 14 and a CPU that controls the display of the display devices 21 and 22. The motor drive unit 55 is composed of a power transistor or the like, and drives the motor 14 by supplying a power supply current to the motor 14 via the safety switch S by conduction of the power transistor.

Then, the photodiode 20 and the controller 5
3 and 3 constitutes a rotation speed detecting means for detecting the rotation speed of the cutter 35. The control device 53 also has a function as a stopping unit that stops the motor 14.

Next, the operation of the cooking device 10 of the above embodiment will be described.

First, as shown in FIGS. 1 and 2, the container 30 containing the material to be cooked is placed on the placing portion 12 of the cooker main body 11. Next, the mode switch 26 is operated to enter the set number mode, and the number of rotations for cooking the material to be cooked is set by the setting switches 23a to 23d as desired. The number of rotations set by the setting switches 23a to 23d is displayed on the display 21 and stored in the RAM 51.

Then, the lid 41 mounted on the container 30 is rotated so that the operation projection 42 is inserted into the recess 29a of the tubular portion 29. With this entry, the safety switch S is turned on, and the motor 14 is ready to be driven. Next, when the on / off switch 25 is pressed, the control device 53 causes the motor drive unit 55 to
To drive the motor 14.

The drive shaft 14a is rotated by the drive of the motor 14, and the driven pulley 17 is rotated via the drive pulley 15 and the belt 18. The drive shaft 16 is rotated by the rotation of the driven pulley 17, the rotation shaft 32 of the container 30 is rotated together with the drive shaft 16 via the couplings 16a and 33, and the cutter 35 is rotated together with the rotation shaft 32.
The rotating blade 34 cuts the material to be cooked by the rotation of the cutter 35.

On the other hand, the rotation of the driven pulley 17 causes the photodiode 20 to output a pulsed light receiving signal (pulse). The control device 53 counts the number of the pulses to obtain the rotation speed of the cutter 35. When this number of rotations matches the number of rotations displayed on the display 21, the control device 53 stops the operation of the motor drive unit 55 and causes the motor 1 to operate.
The drive of 4 is stopped.

That is, since the motor 14 is stopped when the number of rotations of the cutter 35 reaches the set number, the number of rotations of the cutter 35 becomes constant regardless of variations in the performance of the motor 14, and as a result, the material to be cooked It will always be possible to cook in a constant state.

When the same material to be cooked is cooked in the same state, a container 30 containing a new material to be cooked is placed as shown in FIG. 2 and only the on / off switch 25 is operated. . By this operation, the cutter 35 is rotated by the number of rotations stored in the RAM 51 and the material to be cooked is cooked in the same state. That is, when the same cooking is repeatedly performed, the number of rotations is first set by the setting switches 23a to 23d, and thereafter, the on / off switch 25 only needs to be operated.

When it is not known how many revolutions the cooked material should be cooked, after placing the container 30 as shown in FIG. 2, the changeover switch 26 is operated to set the continuous mode, and the same procedure as above is performed. The lid 41 is rotated to move the operation protrusion 42 to the tubular portion 29.
Then, the motor 14 is driven by operating the on / off switch 25 while entering the concave portion 29a. The cutter 35 is rotated by driving the motor 14, and the material to be cooked is cooked by the rotation of the cutter 35.

Then, while observing the state in which the material to be cooked is being cooked, the on / off switch 25 is operated and the motor 14 is stopped in anticipation of the fact that the material is in a good state. The rotation speed of the cutter 35 at this time is displayed on the display 21.
Since it is displayed in, the number of rotations should be set from the next time.

Further, as one of the methods of using the continuous mode, the cutter 35 is rotated and the number of revolutions displayed on the display 21 is observed. When this number of revolutions reaches a predetermined number of revolutions, an on / off switch is used. 25 may be operated to stop the driving of the motor 14 to perform predetermined cooking. in this case,
Since the rotation of the motor 14 is 3000 to 5000 revolutions / minute, the numerical value of the display 21 changes in a short time as the motor 14 rotates, but it is possible to visually recognize the numerical value of the second digit or more.

Next, the case where the selection switch 24 is operated will be described.

When the selection switch 24 is operated, the type of the material to be cooked stored in the ROM is read and displayed on the display 22 at each operation, and the number of rotations suitable for the type is also read. Then, the number of rotations is displayed on the display 21. For example, "Sardine" is displayed on the display 22,
For example, “1000” is displayed on the display 21. When it is desired to increase or decrease the number of revolutions "1000" to cook in a desired state, the setting switch 23 is operated.

Then, the on / off switch 25 is operated to drive the motor 14. When the rotation speed of the cutter 35 rotated by the drive of the motor 14 matches the rotation speed displayed on the display 21, the control device 53 causes the motor 14 to rotate.
Is stopped and desired cooking is performed.

As described above, since cooking is performed based on the number of revolutions of the cutter 35, the cooking state can be kept constant regardless of variations in the motor 14.

[0040]

As described above, according to the present invention, the material to be cooked can be cooked with the cutter rotating at a constant speed, so that the material to be cooked can be cooked in a constant state regardless of variations in the performance of the motor. be able to.
