How a Washing Machine Works LapWoon Keung 2005
What is a Washing Machine A washing machine is an machine that washes clothes, linen Was made to help wash clothes easier
Steps to Cleaning Clothes Decide on: Load size (small, medium, large, x- large) –Temp –How machine should agitate –Time
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.
History of the Machine that Washes Before washing machines people cleaned clothes in the stream Then its beat with rocks or they scrubs clothes clean on a washboard.
History of the Machine that Washes First electronic: American - Alva J. Fisher –Had Electronic vertical-tube machine with built-in turbo washers or Vertical axle fitted with blade. Alva J. Fisher - Thor
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
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 Crank to turn agitator
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
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
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
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
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
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
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
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
Pump Vanes of the bottom layer of the pump: Push water around The pump can reverse direction –Spins different way while doing different jobs.
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
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
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
Control Cycle switch Speed and temp. control switch Water level control switch plumbing Designed before micro-controllers were being used in appliances
