what happens inside a dishwasher?

Answer 1

Basically, a dishwasher is a robot that cleans and rinses dirty dishes. Humans have to load the dishes, add detergent, set the proper washing cycles and turn it on, but the dishwasher accomplishes a whole series of functions by itself. A dishwasher:
* Fills itself with water
* Heats the water to the appropriate temperature
* Automatically opens the detergent dispenser at the right time
* Shoots the water through jets to get the dishes clean
* Drains the dirty water
* Sprays more water on the dishes to rinse them
* Drains itself again
* Heats the air to dry the dishes off, if the user has selected that setting

Although dishwashers are watertight, they don't actually fill with water. Just a small basin at the bottom fills up. There, heating elements heat the water to 130 to 140 degrees Fahrenheit. Then a pump propels the water up to the water jets, where it is forced out and sprayed against the dirty dishes. Think about a garden hose with no nozzle – if you put your thumb over the end of the hose, decreasing the space for the water to come out, it sprays out more forcefully. The dishwasher's jets work on the same principle. The force of the water also makes the arms that hold the spray jets rotate, just like a lawn sprinkler.

When the washing and rinsing is finished, the water drains down to the basin again, where the pump propels the water out of the dishwasher. Depending on the type of dishwasher, the drain water might go right into the pipes under your sink, or travel up a hose into your sink itself. The final step in a wash cycle is optional – the dry cycle. The heating element at the bottom of the dishwasher heats the air inside to help the dishes dry. Some people just let them dry without heat to save energy.


EXTRA INFO!
Josephine Cochrane invented the modern dishwasher in 1886. Cochrane was a wealthy socialite whose servants kept chipping her fine china while hand washing it. She developed a rack and water jet system that debuted at the 1893 Chicago World Fair. The company she founded eventually became KitchenAid.

Answer 2

Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot (55-65 degrees Celsius or 130-150 degrees Fahrenheit) water on the dishes. First detergent-added water for cleaning purposes, then clean water (though sometimes with a rinsing aid added) to remove the detergent residue. The hot water may be direct from the supply or brought up to temperature by an element. As there is no human contact during the process, strong detergents may be used which would be too alkaline for habitual exposure to the skin. Some dishwashers also contain a heating element to achieve fast drying of the dishes.

Answer 3

Dishes get washed, then sometimes you have to put some back in as dishwashers aren't that reliable, better just DIY

Answer 4

Just envisage an automated car-wash with sealed doors front and back, and that's what happens inside a dishwasher.

Answer 6

When you close the door. A wee man comes ut of the drain at the bottom and starts to scrub all your dishes with a dish mop.

Answer 7

water gets heated to a really high temperature and then the special soap you put in, combines with the water and it gets spun by a fan (usually on the bottom of the washer) and swirled in a hot boiling soup os soap all over your dishes and then rinsed in a layer of just water, while the remains of the soapy water, and later the rinse water, is flushed out.

Answer 8

wet and soapy ( sprays fresh water on the dish's to remove loose particles - drains particles - sprays water on the dishes and the soap container ( recycles the soapy water while adding fresh )- drains the soapy water while rinsing with fresh water - drys with air ( heated on some cycles )

lots of variations depending on the cycles you select

Answer 9

the water heats up the soap makes suds and cleans the dishes and then water comes on and rinses the soap off and then it heats up again and drys the dishes

Answer 10

First you have to get a good looking fella bundle him in the washer, switch it on and then wash the dish!
