Working Principle of Washing Machine and its types

How does the washing machine work?

  • In watching machines, the mechanical energy of an agitator is used to generate centrifugal force for clockwise and counter-clockwise motions for strong mixing of detergent water and garments in a water drum.
  • The centrifugal force pushes to throw garments at the rough surface of the drum. The strong interaction of detergent water with garments removes dirt and flows in the water.
  • After 10-15 minutes of agitation of the water, dirty water is drained out from the drum

Which washing machine type is more useful?

What’s a semi-automatic washing machine, what’s the difference between semi-automatic and fully automatic washing machines, and why are top-load washing machines better for people with less space in their apartments? Read on to find out!

Semi-automatic washing machines

  • This machine uses some automatic options for washing machines
  • This means that you will need to do some parts manually, like filling up the water in the tub before starting the machine, or if you have a twin-tub semi-automatic washing machine, you’ll need to move the washed clothes into the drying tub
  • These are always going to be top loading

Fully-automatic washing machines

  • This machine does everything at the touch of a button
  • This washing machine comes with a single tub that acts as a washer, and dryer and also rinses the clothes
  • These may come as front and top-load machines, and the programs and efficiency vary between the machines, depending on the brand
  • Advantage of Front loading Machine
    • Less water consumption
    • Large capacity of washing
    • Better cleaning
    • More cycle options
    • More energy efficient
  • The disadvantage of Front loading Machine
    • More costly machine
    • Longer washing time due to long wash cycles
    • More vibration during operation
    • Water may  trap inside to cause malodor

Front-load washing machines

  • A front-load washing machine is a fully-automatic washing machine that loads from the front side
  • These machines usually consume less water and energy, and usually yield better laundry results than their top-load counterparts.

Top loading washing machines

  • Both manual washing machines and fully-automatic washing machines come in a top-load form
  • These kinds of machines are loaded from the top. This is good for people who want a machine in which they don’t need to bend down completely to load the clothes in the machine
  • Fully-automatic top load washing machines usually take up less space, so they’re good for people looking to fit a washing machine into a narrower space.
  • Advantage of Top  loading Machine
    • Less expensive
    • You can add some laundry mid-cycle
    • Shorter washing time
    • Low vibration
    • Simple control panel
    • Easy to operate
  • Disadvantage of Top  loading Machine
    • Lower cleaning performance
    • Uses more water and electricity
    • Smaller capacity
    • Longer drying time

What detergent or washing powder you can select?

  • No matter which type or size of washing machine you can select liquid or any washing powder.
  • Detergent must be mixed with water
  • Using a hand wash detergent in a washing machine can leave you disappointed with your laundry results and can even affect the performance of your washing machine
  • There are many detergents to meet  laundry demands you to have and are uniquely formulated to ensure the best performance inside your washing machine

Which motor is used in the washing machine?

  • Three phases brushless AC motor is used for washing machine
  • The universal brushed motors are used with Triode Alternating Current switch (TRIAC) control. However, with the advent of new electronic devices, these drives are becoming out-of-date
