Procedure of

working principle of a washing machine :-

A washing machine by spinning at 800 to 1600 Rpm help and dirt with it to leave the surface of the cloth via Centrifugal force and into outlet pipes hence utilizing centrifugation to both clean and partially dry the cothes loaded in it thus the processes are electrically controlled such as the drum valves pump works to help get rid of the water. The valve lets clean water in again into the drum

Soaking :-

If is used to dip Clothes in detergent water to remove dirt from the clothes in this function customer need to select soak from a panel , soak this function is available with was timer in 42 min of washing 27 min is soak and 15 min machine will wash the clothes

Washing :-

During the washncycle A large plastic green tuns Around moving your clothe through the water when the wash is finished , The piump Drains the water from the pouter drum

Rinsing :-

The dirty ,soapy water is drained then the wasing machine is refilled and your clothes are rewashed in clean water sping. All the water is drainedncompletely then Your clithes are spun very fast and excess water is removed thanks to centrifugal force

Dryer:-

They work by pushing warm dry air through your wet washing to extract moisture, then cooling the now humid air in a heat exchanger to condense the moisture, which is collected in a tank or pumped down the drain. The (now dry) air is reheated and the cycle repeats.

1 :- State flow

systematic solution of a problem is possible with sequential unambiguous and realizable finite process step set . This set is called algoruthm and it is one of the most important part of the Programming languages in flow . in flow diagram based algorithm

CONTROL LOGIC OF A WASHING MACHINE:.

It checks for the extent of dirt and grease, the amount of soap and water to add, direction of spin, and so on. The machine rebalances washing load to ensure correct spinning. Else, it reduces spinning speed if an imbalance is detected. Even distribution of washing load reduces spinning noise.

The two inputs are given for the power and water supply. Once the inputs are given outputs are displayed by the flow chart as per the given sequence. The system are observed for sometime then it is checked and the process is completed by green light as displayed.

2:-GEAR SHIFT LOGIC:

A gear shift mechanism for a manual transmission includes a shaft axially movable for selecting shift planes and rotatable for engaging the gears defining the shift planes. The shaft is held in a reference shift plane by two helical springs.
