b. Functions and operates
According to Woodford (2016), automatic washing machine are electrically controlled which consist of inner drum, valves, water pump and heating element. The washing machine working by switching one stage to another stage in a sensible sequence:
1. First put dirty laundry into washing machine and pour detergent either in the drum itself or in detergent tray up above.
2. After that switch on the power and set the program wanted.
3. Washing machine program the water valves so hot or cold water enter the washing machine and fill the outer and inner drums. The water will enters from the top and trickles down through the detergent tray and washing down the detergent into the washing machine.
4. When the water is fill enough …show more content…
After the water is hot enough it will switch off the heater and it will switch on motor to rotate the inner drum back and forth, sloshing the clothes through the soapy water.
7. The detergent work with water pulls out the dirt or stain from the clothes and trap the dirt in the water.
8. After finish wash the washing machine will switch on the water valves to drains from both drums. Then will be rinse mode where the pump is switched on to help empty the water in the drums.
9. Now the microcontroller will invoke the water valves to switches on again to allow clean water enter the drums.
10. The microcontroller invoke the inner drums to rotate back and forth again in order the clean water to rinses the clothes that have detergent. Then will empties the drums again and repeats this process few times to get rid all the soap.
11. After the clothes are rinsed from the detergent then the microcontroller invoke the inner drum rotate in very high speed, speed may reach around 80 mph. All the clothes will flung against the outside edge of the inner drum, then the water contain in the clothes will extract out to through the inner drum tiny holes to the outer drum.
12. Next the he pump drain out the remaining water from the outer drum and wash cycles is
