があった。Problems to be Solved by the Invention In such conventional electric cookers, although the motor is protected by circuit interruption, the cause of the abnormality is not removed.
For example, in the case of a mixer, it is not possible to restart it as is.
It is necessary to remove the material caught between the knife and the container.
It was inconvenient to use and dangerous. Furthermore, when a fuse is provided, there are problems such as the need to replace parts.

ようにしだものである。Means for Solving the Problems In order to achieve the above object, the present invention includes an overload detection device that detects overload based on the number of rotations of the motor shaft, and a device that detects the rotational direction of the motor based on the output of the overload detection device. The motor rotation direction control device is equipped with a switching motor rotation direction control device, and further limits the number of times the motor is switched between forward and reverse rotation, and then stops the motor.

もし回転数がNoより大きければそのまま正転を継続し
、もし回転数がNoより小さければ再度瞬時逆転する。Operation The present invention has the above-described configuration, so that the number of rotations N counted by the overload detection device is the number of rotations N preset as the overload state of the motor. If it is smaller than , the υ motor rotation direction control device is activated by the output of the overload detection device, the motor instantaneously reverses, then rotates forward again, counts the number of rotations again,
If the number of rotations is greater than No, normal rotation continues, and if the number of rotations is less than No, instantaneous reverse rotation occurs again.
ただし正逆転の切り替え回数が予め設定された回数にな

実施例
以下、本発明の一実施例について第1図および第2図を
参照しながら説明する。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

された回数n。になるとモータ2を停止する。In the figure, when the switch 1 is turned on, the motor 2 first rotates in the normal direction, and the rotation speed N of the motor shaft is detected by the rotation speed detection device 4 via the photoelectric sensor 3, and is set in advance as an overload state by the calculation device 5. The rotation speed N. compared to
If N>No, the motor continues to rotate in the normal direction. However, if N≦No, the motor 2 receives the output of the rotation speed detection device 4 and is instantaneously reversed by the rotation direction control device 6. At the same time, the number n of reverse operations is currented by the calculation device 6, and the motor 2 is rotated forward again. do. And further rotation speed N
is detected, and if N>No, normal rotation continues. Alternatively, if N≦No, instantaneous reversal, counting of the number of reverse rotations, and detection of nine normal rotations are repeated, and the number of reverse rotations n is a preset number n. When this happens, motor 2 is stopped.

全性の高い電動調理器を提供できる。Effects of the Invention As is clear from the above description, the present invention provides a device for detecting overload of a motor, and a motor rotation direction control for switching the rotation direction of the motor in response to the output of the overload detection device. The system also limits the number of times the motor switches between forward and reverse rotation, and then stops the motor, so if an overload is applied to the motor, the motor instantly reverses and then rotates forward for a predetermined number of times. The load (material) causing the overload can be removed repeatedly within the range, improving the usability of an electric cooker such as a mixer, and providing a highly safe electric cooker.
