Embodiment Construction

[0018] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0019] A fully automatic washing machine based on PLC control mainly includes a relay group, a programmable controller and a frequency converter. Among them, the relay group is connected with the programmable controller, and the programmable controller is connected with the frequency converter. The relay is the main executive module, and its opening and closing directly control the circuit, realizing the control of the motor.

[0020] The above-mentioned PLC sends digital commands to control the coil work of the relay.

[0021] As the core of the control, the above-mentioned PLC samples various external input signals.

[0022] The above-mentioned PLC uses a timer to record the time of the motor's forward rotation, reverse rotation, drainage, dehydration and alarm, and uses a counter to record the times of the motor's forward rotation, reverse rotation, drainage, ...

Abstract

The invention discloses a full-automatic washing machine based on PLC control. The full-automatic washing machine based on the PLC control mainly comprises a relay set, a programmable controller and a transducer. The relay set is connected with the programmable controller, the programmable controller is connected with the transducer, the relay serves as a main execution module, and the on and off of the relay directly control a circuit to realize the control for the motor. The full-automatic washing machine based on the PLC control overcomes the problems of easiness in damage, large energy consumption and noise generation in working of a traditional relay-controlled washing machine and provides the full-automatic washing machine featured with long life span, small energy consumption, high reliability and fast running speed. According to the control system, the PLC serves as the control core, various outside input signals are sampled, wherein the sampling includes a start button, stop signals, high / middle / low water level detection and the like, and after performing logical operation or data treatment in the PLC, various output signals are provided for controlling the action of a water inlet valve and a water discharge valve and controlling a motor drive device so as to control the forward rotation, reverse rotation and dehydration of the motor.

Description

technical field [0001] The invention relates to a fully automatic washing machine, in particular to a fully automatic washing machine based on PLC control. Background technique [0002] The fully automatic washing machine is to set the whole process of laundry into multiple programs, select one of the programs when washing, turn on the tap and start the washing machine, and the laundry process will be carried out automatically. When the laundry is finished, an alarm will be generated. With the rapid development of society and the acceleration of people's life rhythm, fully automatic washing machines have also achieved relatively rapid development and technological innovation and creation. The emergence of PLC system provides a new platform for the automatic control of fully automatic washing machines. New lines of inquiry were developed. Since the price of other systems is very expensive compared to the PLC system, we can use the PLC system to realize the development of wa...
