  • Slide 2 - What is a Washing Machine A washing machine is an machine that washes clothes, linen Was made to help wash clothes easier
  • Slide 3 - Steps to Cleaning Clothes Decide on: Load size (small, medium, large, x-large) Temp How machine should agitate Time
  • Slide 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.
  • Slide 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.
  • Slide 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”
  • Slide 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
  • Slide 8 - History of Washing Machine 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. 1915 Crank to turn agitator
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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.
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 21 - Control Cycle switch Speed and temp. control switch Water level control switch plumbing Designed before micro-controllers were being used in appliances
  • Slide 22 - About Me I love music, especially hardcore metal rock. Some bands are: Ill Nino, Dragpipe, Bush, Boiler Room, Brand New, Motograter, Project 86, Powerman 5000, Drowning Pool, Full Devil Jacket, Puya, Adema, Clutch, Coal Chamber, The F-Ups, The Kittie, Korn, SOAD, The Union Underground, Sworn Enemy and Mushroom Head, plus more.
