5History of the Machine that Washes Before washing machines people cleaned clothes in the streamThen it’s beat with rocks or they scrubs clothes clean on a washboard.
6History of the Machine that Washes First electronic: American - Alva J. FisherHad Electronic vertical-tube machine with built-in turbo washers or Vertical axle fitted with blade.Alva J. Fisher - “Thor”
7History of Washing Machine Replaced steam boiler and the washtub; wooden bins that was filled with soap hot waterFirst mechanical washing machine used heavy blades
8History of Washing Machine Principle of tossing clothes inside in a rotating cylinderUsed 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
9Inside of a Washing Machine Two Steel TubsOuter = 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
10Inside a Washing Machine There are 3 pulleyOne side of frame moves upOther side frame goes downHas Damping SystemUses friction to absorb force of the dangling pulleys
11Inside a Washing Machine Each four corner has mechanism that:Works like disc brakeAttached to springSqueeze two pads against metal plateAttached to black frame
12Plumbing 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
13Plumbing Hook for two water lines on back Cold Hot Hooked to the body of the solenoid valveSolenoid valveFeed into a single hoseHot valve, cold valve or both valve will open
14PlumbingBefore hose release water into tub, it is send through anti-siphon devicePrevent water from being sucked back into the water lineWhite plastic device has big opening that allows air inSuction would only get air, not water
15Plumbing Water Inlet Water enters that way Nozzle to the right: Overflow portConnected to pipes that dump water onto floorGoes to floor instead of the tub and motor

17Pump Vanes of the bottom layer of the pump: Push water around The pump can reverse directionSpins different way while doing different jobs.
18Pump Clutch is hooked up to pump Drain hose loops all the way to the top of machineOne end is hooked to bottom of tubOpen to atmosphere
19Drive Mechanism A piece of rubber seals the outer tub to the gearbox Has 2 jobsAgitate clothes: Moving them back and forth inside tubSpin Tub to force water outDrive Mechanism
20Inside the Gearbox Pulley Pie-shaped gears has link on it Washer goes to spin cycle - locks up, everything spins at same speedGears - angled teeth
21Control Cycle switch Speed and temp. control switch Water level control switch plumbingDesigned before micro-controllers were being used in appliances
