First mechanical washing machine used heavy blades

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

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
Drive Mechanism

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
