– in dishwashers, this rotating 'water fan' recirculates the tankful of
water and detergent solution back over dishes after passing it through a
– section of a dishwasher pump assembly, including the wash impeller
(which see) that is responsible for spraying the dishes. The other
section of the pup, or sometimes a separate pump/motor assembly, is the
drain pump, whose only function is to empty the water form the tank
after the wash cycle is complete.
– refrigerator system that stores a quantity of chilled water, and
delivers, it on demand, to an outlet outside the refrigerator, and
directly into a glass or other container. Saves energy by reducing door
openings. Uses same water supply as the icemaker.
(pressure switch) – in a clothes washer, this switch, usually
adjustable, is activated by the water level in the tank, and turns the
fill valve off and the timer motor on, starting the agitate cycle. See
also 'float switch'.
(fill valve) – a commonly used device in appliances, these valves use
house supply water pressure to open and close. This is done by
valve coil that opens a small pilot hole, allowing water pressure to
lift the valve's diaphragm off the valve seat, allowing water flow.
– unit of power measurement; 1 joule/second; the power dissipated by a
current of 1 ampere flowing across a resistance of 1 ohm; in Ohm's law,
watts = volts x amps
– the common rating of power output in microwave ovens is in watts. To
take a rough measurement of an oven's output, heat one liter of water on
'high' for 2 minutes, 3 seconds, measuring the water's start and finish
temperatures in F. Multiply the difference by 19.4 to return the wattage
output of the microwave's magnetron.
– the assembly using rubber rollers to 'squeeze' water out of laundered
clothes, as opposed to using centrifugal force, as do modern washers.
