Objective
“To minimize Human Effort in washing
a dish”
About Dishwasher
A dishwasher is an electrically operated automated machine used for washing, rinsing and drying the
dishes.

Software:WPL SoftwareProteusAltium
About PLC
Programmable Logic Controller (PLC) is a digitally operating electronic apparatus that uses a programmable memory for internal
storage of instructions for implementing specific functions.
Advantages of PLC over uC
They are Proven Systems to work in Industrial environments
Direct Interoperability to other industrial devices
Very Rigid compared to microcontroller
No Programming background required
PLC used….
Model No- DVP32ES200R
MPU points: 16 / 20 / 24 / 32 / 40 / 60
Program capacity: 16k stepsBuilt-in with 3 COM ports:
1 RS-232 port and 2 RS-485 ports
Built in with 12-bit 4 A-D/2 D-A
Handy instructions for frequency inverter16 Digital Input (24VDC sink/source) / 16 Digital Output
Specifications of Delta DVP-ES2
Formation of a High Pressure Water Jet:
A high pressure pump sucks water and accelerates it strongly.
The accelerated water runs through the pump system and gets to the high pressure nozzle.
And then nozzle produces the high pressure water jet.
Water Jet
Sensing Distance: Up to 1m
Emitter: 1mW red laser diode
Operating Voltage: DC 4.5 VDC - 5.5VDC
Operating Current: 25mA
Response Time: 2ms
Laser Break Beam Sensor
Motor used for Conveyor Belt
Low-Speed Synchronous AC Motor
Motor rotates with speed proportional with the frequency.
Fluctuation in load does not affects the rotation.
Can be driven in both the directions.
Long rated life of 10,000 hours.
Water Level Indicator
Water Level Indicator
There is no conductive path between the indicating probes and the common probe so it remains in cut off region.
Water Level Indicator
There is a conductive path between the indicating probes and the common probe so BJT goes into active region.
Stationary Brushes
Sprinkler Motor Brushes Water Jet
Utensil
Conveyor Belt
