  3. Steps to Cleaning Clothes • Decide on: Load size (small, medium, large, x-large) • Temp • How machine should agitate • Time

  4. Steps to Cleaning Clothes • Fill tub with clothes; Fills with water; Agitator starts to spin; • After agitating • Drains water • Spins clothes • Refills; agitates more • Drains • Spins more.

  5. History of the Machine that Washes • Before washing machines people cleaned clothes in the stream • Then it’s beat with rocks or they scrubs clothes clean on a washboard.

  6. History of the Machine that Washes • First electronic: American - Alva J. Fisher - 1901 • Had Electronic vertical-tube machine with built-in turbo washers or Vertical axle fitted with blade. Alva J. Fisher - “Thor”

  7. History of Washing Machine • Replaced steam boiler and the washtub; wooden bins that was filled with soap hot water • First mechanical washing machine used heavy blades

  8. History of Washing Machine 1915 Crank to turn agitator • Principle of tossing clothes inside in a rotating cylinder • Used in 1850 in a English laundry. • Used in 1840 by the French: Industrial model, double sheathing, 4 compartments, driven by a crank.

  9. Inside of a Washing Machine • Two Steel Tubs • Outer = Seals water. Mounted so that inner can move without banging. • Inner = Holds clothes and with the agitator in the middle with holes around the side of the tub. Attached to gearbox

  10. Inside a Washing Machine • There are 3 pulley • One side of frame moves up • Other side frame goes down • Has Damping System • Uses friction to absorb force of the dangling pulleys

  11. Inside a Washing Machine • Each four corner has mechanism that: • Works like disc brake • Attached to spring • Squeeze two pads against metal plate • Attached to black frame

  12. Plumbing • Jobs • Fills washing machine with correct temperature of water • Re-circulate water from bottom of the wash tub back to the top, during wash cycle

  13. Plumbing • Hook for two water lines on back • Cold • Hot • Hooked to the body of the solenoid valve • Solenoid valve • Feed into a single hose • Hot valve, cold valve or both valve will open

  14. Plumbing • Before hose release water into tub, it is send through anti-siphon device • Prevent water from being sucked back into the water line • White plastic device has big opening that allows air in • Suction would only get air, not water

  15. Plumbing • Water Inlet • Water enters that way • Nozzle to the right: Overflow port • Connected to pipes that dump water onto floor • Goes to floor instead of the tub and motor

  16. Pump • Re-circulates water and drains it • Has 2 separate pump in one • Bottom half: Hooked to drain line • Top half: Re-circulates wash water

  17. Pump • Vanes of the bottom layer of the pump: Push water around • The pump can reverse direction • Spins different way while doing different jobs.

  18. Pump • Clutch is hooked up to pump • Drain hose loops all the way to the top of machine • One end is hooked to bottom of tub • Open to atmosphere

  19. Drive Mechanism • A piece of rubber seals the outer tub to the gearbox • Has 2 jobs • Agitate clothes: Moving them back and forth inside tub • Spin Tub to force water out

  20. Inside the Gearbox • Pulley • Pie-shaped gears has link on it • Washer goes to spin cycle - locks up, everything spins at same speed • Gears - angled teeth

  21. Control • Cycle switch • Speed and temp. control switch • Water level control switch plumbing • Designed before micro-controllers were being used in appliances
