ULTRASONIC WASHING APPARATUS CAPABLE OF CONTROLLING DUAL FREQUENCY OF ULTRASONIC VIBRATOR AND CONDUCTING IoT-BASED REMOTE CONTROL

摘要

The present invention relates to an ultrasonic washing apparatus capable of controlling a dual frequency of an ultrasonic vibrator and conducting Internet of Things (IoT)-based remote control, which is able to notify a remotely located worker of the inclination status of a dishwasher, thereby allowing the worker to control and check the operation status of the dishwasher from a remote place. According to the present invention, the ultrasonic apparatus comprises: an ultrasonic wave generation means which includes one or more transducers; a frequency generation means which generates and outputs a frequency for oscillation in the shape of a sine wave, which oscillates the transducers; an output value measuring unit which measures and outputs an output value of an ultrasonic wave generated by the ultrasonic wave generation means; an inertia measuring means which measures change values on front, rear, upper, lower, left, and right sides of the ultrasonic washing apparatus to output the values as inclination measurement values of the ultrasonic washing apparatus; a control means which, when the ultrasonic wave output value is not a maximum value within a reference value range, generates an ultrasonic wave generation control signal to generate and output a frequency for oscillation as a maximum value within the reference value range, outputs the ultrasonic wave generation control signal to the frequency generation means, and, when the inclination measurement value for the ultrasonic washing apparatus exceeds the reference value range, generates and outputs a position adjustment notification information of the ultrasonic washing apparatus; and a user interface means which outputs a menu item selection signal to the control means, and receives the status information during operation of the ultrasonic washing apparatus from the control means to output the status information. Accordingly, the present invention enables an administrator or a worker to control the operation of a dishwasher or to check the operation status regardless of his or her position.;COPYRIGHT KIPO 2019
