Automatic control device and control method of rotational force of tray using weight sensor

摘要

The present invention relates to a control method for automatic cooking of a microwave oven. In particular, the tray motor of the microwave oven driving circuit of the tray motor can be prevented by automatically controlling the rotational force of the tray according to the cooking weight of the microwave oven. Install the double structure contact point to change the driving force, and install the tray motor relay to turn on / off the contact point of the double structure.When auto cooking starts, turn on the start relay and output control relay, and then detect the weight. If no weight is detected, turn off the start relay and output control relay after displaying the error because the tray is not inserted bad.If the weight is detected, the detected weight is compared with the reference weight. If the reference weight is greater than the weight, turn on the contact a of the tray motor relay, and the detected weight is greater than the reference weight. In a large case, the present invention relates to a tray torque automatic control device and a control method using a weight sensor that advances cooking until the completion time of cooking after turning on the b contact of the tray motor relay.
