,．． 71 doso° for 1 stirring, 7 kneading/3j processing
The present invention relates to a cooking machine such as a cooker, and relates to a drive control mechanism for a rotating body of the cooking machine driven by the motor of the cooking machine.

BACKGROUND ART For example, Japanese Patent Publication No. 57-28575 discloses an example in which a speed and time data storage unit is provided in a cooking machine according to the present invention, and a motor is controlled and driven based on the data. An example is given in which the rotational speed is increased intermittently in the order of low speed → medium speed → high speed.However, as in this example, if the rotational speed is increased while the motor is resting, the amount of food to be cooked will increase. Due to the load, it is necessary to supply more than necessary force to the motor, and from low to medium speeds, and from medium speeds, the relative speed is large, and the particles are scattered around. It is not possible to collect the wood blocks efficiently near the rotating body, and the finished cooking of the ingredients is not uniform.Also, the scattered ingredients end up in the container and are wasted, and the container itself has to be cleaned. It also makes things troublesome.

Purpose of the Invention The present invention has been made in view of the drawbacks of the prior art as described above, and provides a rotating body that achieves a uniform finish on the material and prevents the material from being wasted by scattering onto the inner surface of the container. The purpose of this invention is to provide a driving process.

According to the invention (1), a cooking container is placed on a main body case containing a built-in motor, and a rotating body such as a cutting blade stored in the cooking container is rotationally driven by the motor, and the motor is connected to the main body. The motor can be driven at different rotational speeds such as low speed, medium speed, and high speed by a control section provided in the case that stores data on rotational speed and operating time and controls the drive of the motor based on the data. The motor is controlled and driven along a series of rotational speeds and operating times, and the rotational speed of the motor is set to low speed → after the start of cooking.
It is characterized in that the rotation speed is continuously increased in the order of medium speed → high speed at fixed time intervals, and then the rotational speed is alternately changed between two arbitrary rotational speeds at fixed time intervals.

Embodiment The cooking machine of the present invention will be explained based on an embodiment of a food processor and with reference to the drawings.
